Full textThe alimentary allergies in dogs represent about 1% of the dogs dermatosis, it is an illness little known with regard to its etiopathic, diagnosis and treatment.The general objective is to analyze the bibliography since 1990 up to 2003 and to raise the current position of the art on "Alimentary Allergy in dogs". Bibliographical revision was carried out consulting system data-base CAB Abstracts (Commonwealth Agriculture Bureau) and AGRIS. We use for key words: "Dog", "sensitivity", "hypersensitivity", "food" and "allergy". Altogether, 160 works of CAB and 58 of the AGRIS had been collected, adding 218 works. Of these 218 works, 74 writings in other languages, that not in English or Portuguese, and 38 works that had been found in CAB in AGRIS had been left out. Of the 106 remaining studies, 21 had been chosen to be added in this work of revision based on: title of the work, author, sample size, drawing of clear-cut study, impact factor of the publication magazine and subject directly related to the objective of the present study. As for the study drawing had been collected: 10 clinical assays, nine revisions and two surveys. Of the 21 works, 13 had been published in the United States, five in the United Kingdom, two in New Zealand and one in Australia. The years that had more number of publications had been: 1992, 1994 and 2002. The studies had been divided in six subjects to better approach them: definition of concepts, use of atopic dogs as study model, diagnosis and treatment, diets tests, pseudo-allergic reactions and immunological mechanisms. Several times the terminologies is used in wrong way, confusing the true alimentary allergies (IgE mediated) and the adverse reactions to foods, compromising the diagnostic, treatment and prevention of the illness. The immunological mechanisms still are not total defined. Discussion concerning on the "Epidemiological Transition" or on the "Hygienes Hypothesis" had not been found and it was not possible to verify with the analyze of the selected works the possible relation between the brusque change of feeding that the dogs had suffered in finish decade and the probable increase of the number of cases of alimentary allergy in dogs.

The main aim of the thesis is to evaluate type I hypersensitivity reaction cases in dogs in small animal veterinary practice using clinical and laboratory methods. The study was carried out in veterinary practise “Pas pumą” in 2012 – 2013. 38 cases of dogs associated with type I hypersensitivity reaction were registered and a detailed medical history was collected from these dogs owners. Haematological examination was performed. Blood samples were collected from 13 dogs with type I hypersensitivity and from 12 healthy dogs. Immunological test ELISA was done to evaluate canine serum IgE levels concentration. Testing was performed in Lithuanian University of Health Sciences , Faculty of Veterinary Anatomy and Physiology, Department of Immunology laboratory. The analysis of clinical findings has shown the most common type I hypersensitivity clinical presentation among dogs is atopic dermatitis (63.2 percent). The most common clinical features were pruritus (57.9 percent) mainly of the ears and the ventral abdominal wall. Dog gender and breed had no significant effect on type I hypersensitivity reactions. The analysis showed that first signs of allergy for dogs commonly occur from 6 months until 2 years of age (62.5 – 78.57 percent of dogs). Allergies had a higher incidence of recurrence in dogs up...

Resumo: O objetivo deste trabalho foi verificar o efeito do tratamento com 1400W, inibidor seletivo da NOS induzível (iNOS), na adesão in vitro a VCAM-1 e ICAM-1 e na expressão das selectinas VLA-4, Mac-1 e LFA-1 nos eosinófilos da medula óssea e do sangue periférico. A produção das citocinas sintetizadas pelos linfócitos T, Th1 e Th2, também foi avaliada nos homogenatos dos pulmões. Verificamos que o conteúdo de eosinófilos estava aumentado nos pulmões dos camundongos não tratados (controles) a partir de 48h após o desafio com OVA. O tratamento dos camundongos alérgicos com 1400W causou redução no infiltrado de eosinófilos somente em 48h. O tratamento com 1400W aumentou a adesão in vitro dos eosinófilos obtidos da medula óssea a ICAM-1 em 24h-48h, enquanto que a adesividade a VCAM-1 estava diminuída em 48h. Nos eosinófilos do sangue, o 1400W diminuiu a adesão a VCAM-1 em 24h-48h. Na análise por citometria de fluxo não foram observadas alterações na expressão do CD11a sobre os eosinófilos da medula óssea ou do sangue periférico obtidos de ambos os grupos. Um aumento da expressão do CD11b nos eosinófilos da medula óssea dos controles foi verificada em 48h, enquanto que, neste período, CD11b e CD49d estavam diminuídas nos eosinófilos do sangue. O tratamento com 1400W aumentou a expressão do CD11b dos eosinófilos da medula óssea em 24h e 48h e provocou efeitos contrários nas células do sangue ao diminuir sua expressão em 24h e aumentar em 48h. Do mesmo modo, efeitos inversos do 1400W sobre a CD49d foram detectados no sangue quando reduziu sua expressão em 24h, aumentando-a em 48h. O desafio com OVA provocou em 24h aumento nos níveis de todas citocinas nos pulmões dos controles. Não foram observadas outras variações significativas nos níveis de IFN-y e TNF-a em nenhum dos grupos. A eotaxina mostrou pico de produção em 48h-72 horas nos animais controles, quando o tratamento com 1400W reduziu sua síntese nos pulmões. A IL-4, IL-5, IL-10 e IL-13 estavam aumentadas nos camundongos controles em 24h, sendo que picos de IL-4 e IL-13 foram detectados em 24h e 48h, respectivamente. Níveis elevados de IL-5 foram observados em 24-48h. O tratamento com 1400W reduziu os níveis de IL-4 no pulmão em 24h-48h após o desafio com OVA, assim como os de IL-5 em 48h e de IL-13 em 48h-72h. Somente em 72h o 1400W diminuiu o nível da IL-10 no pulmão. Em conclusão, nossos resultados sugerem que o envolvimento do NO na modulação da secreção de citocinas derivadas dos linfócitos Th2 e da eotaxina nos pulmões, bem como na expressão das moléculas de adesão nos eosinófilos da medula óssea e do sangue periférico, pode influenciar a migração celular para os pulmões dos camundongos alérgicos. O NO produz um efeito temporal na expressão/função do Mac-1, sugerindo ser esta a principal molécula de adesão envolvida no efluxo dos eosinófilos da medula óssea em 24h, enquanto o Mac-1 e o VLA-4 estão envolvidos na mobilização dos eosinófilos do sangue periférico para o pulmão em 48h após o desafio antigênico.
Abstract: The aim of this study was investigated the effectiveness of treatment with 1400W, a selective inhibitor of inducible NOS (iNOS) in in vitro adhesion to VCAM-1 and ICAM-1 and VLA-4, Mac-1 and LFA-1 expression in eosinophils from bone marrow and peripheral blood. The cytokines synthesized by T lymphocytes, Th1 and Th2 cells, was evaluated in lungs homogenates. As a result we found that the eosinophils were increased from 48h after OVA challenge in lungs of untreated mice (controls). Treatment of allergic mice with 1400W caused a reduction in eosinophils infiltration only after 48h. 1400W increased between 24-48h the in vitro adhesion of bone marrow eosinophils to ICAM-1, whereas adhesion to VCAM-1 was decreased after 48h. In the blood eosinophils, 1400W decreased adhesion to VCAM-1 between 24-48h. Flow cytometric analysis showed no significant changes in the expression of CD11a on bone marrow and peripheral blood eosinophils obtained from both groups. An increased expression of CD11b on bone marrow eosinophils of controls was observed after 48h, while on that period, CD11b and CD49d expression were reduced in blood eosinophils. In the bone marrow eosinophils, treatment with 1400W increased CD11b expression in both 24h and 48h, but in the blood cells caused adverse effects by decreasing expression after 24h and increase after 48h. Similarly, the opposite 1400W effect was detected in the blood cells when CD49d expression had been reduced after 24h and increased after 48h. The OVA challenge resulted in increasing the levels of all cytokines in the control lungs after 24h. There were no other significant variations in the IFN-y and TNF-a levels in both groups. In control animals, the eotaxin showed peak production between 48-72h, while 1400W treatment reduced its synthesis in the lungs. IL-4, IL-5, IL-10 and IL-13 were increased in control mice after 24 hours, with peaks of IL-4 and IL-13 were detected after 24h and 48h, respectively. Elevated levels of IL-5 were observed between 24-48h. Treatment with 1400W reduced the levels of IL-4 in lung between 24h-48h after OVA challenge, as well as IL-5 in 48 hours and IL-13 in 48h-72h. Only after 72h 1400W decreased the level of IL-10 in the lung. In conclusion, our results suggest that the involvement of NO in modulating the secretion of cytokines derived from Th2 lymphocytes and eotaxin in the lungs, as well as in the adhesion molecules expression in bone marrow and peripheral blood eosinophils may influence cell migration to the lungs of allergic mice. NO produces a temporal effect on the expression / function of Mac-1, suggesting that the main adhesion molecule involved in the efflux of bone marrow eosinophils after 24h, while Mac-1 and VLA-4 were involved in the mobilization of peripheral blood eosinophils to the lungs in 48 h after antigen challenge.

Abstract: Horse respiratory diseases is second most commom cause of poor performance and premature retirement, which the one are musculoskeletal disorders. The stabling and poor quality feedings may the favor predispose of diseases in airways. In order we measure the influence of the types of bedding used in the horse stalls about responses allergic airway. Three groups of five horses each are formated, two groups kept in stables but each group with a different type of bedding (autoclaved wood- MA shaving and sawdust-SE) . The third group is the control and stays at pasture. The groups remained in this condition for 45 days with biweekly reviews (D0, D15, D30 and D45). It was realize the physical examination, venous and arterial blood samples collection to realize hemogram and hemogasometry analysis, the bronchoalveolar lavage samples was colected to realize the cytological analysis and to measure alkaline phosphatase. In addition, samples of the beds (clean and dirty) and haylage was collected to realize mycological analysis. In the physical examination was noticed higher intensity of coughing and sneezing at SE group. Hematological analysis remained within the normal standards. Findings of hemogasometric analysis were observed the biggest pH values at horses to pasture (7.47 ± 0.02). At stables horses was observed smaller values of partial pressure dioxide (D15 to D45), (values between 38.3 to 43.7 mmHg) to horses to pasture (values between 43.7 to 46.5 mmHg).

Resumo: As afecções do sistema respiratório são a segunda causa de queda de desempenho e afastamento dos equinos do esporte ou trabalho, as quais estão atrás somente das desordens musculoesqueléticas. A estabulação e alimentação a base de fenos predispõe os equinos a inalação de grande número de agentes irritantes as vias aéreas. No intuito de mensurar a influência dos tipos de cama utilizado em baias de equinos nas respostas alérgicas das vias aéreas estudou-se 3 grupos com 5 equinos cada sendo dois mantidos em cocheiras com diferentes tipos de forração à base de madeira (maravalha de pinus autoclavada-MA e serragem-SE) e por último um grupo controle à pasto por 45 dias com avaliações quinzenais (D0, D15, D30 e D45). Foi realizado nestes momentos o exame físico, coleta de amostras de sangue venoso e arterial para realização de hemograma e hemogasometria respectivamente, lavado broncoalveolar com análise citológica e mensuração de fosfatase alcalina, além de amostras das camas (limpa e suja) e feno pré-secado para análise micológica. No exame físico foi notado tosse e espirros em maior intensidade e número nos equinos do grupo SE. A análise hematológica permaneceu dentro dos padrões de normalidade. Já nos achados hemogasométricos os maiores valores de pH foram observados nos equinos à pasto (7,47 ± 0,02). Nos grupos embaiados foi observado valores de pressão parcial de dióxido, de D15 à D45, inferiores (valores entre 38,3 a 43,7 mmHg) ao grupo a pasto (valores entre 43,7 a 46,5 mmHg)...

Full textABSTRACT - Allergen immunotherapy is a well-established treatment for canine atopic dermatitis (CAD), but new non-invasive, safe, effective and at-home easy-to-use vaccine-delivery routes that promote compliance are needed. Epicutaneous immunotherapy (EPIT) is a new promising alternative route that takes advantage of the skin’s unique immunological features and high accessibility. Our goal was to assess the feasibility, efficacy, and safety of EPIT in CAD. Sixteen dogs (9 French bulldog (FB) and 7 labrador retriever (LR) dogs) with spontaneous non seasonal CAD and positive allergen-specific IgE (sIgE) serology for domestic mites (HDM) were enrolled for a weekly, 12-hour allergen-containing patch application, over 12 weeks. A costume-made 3D-printed device was developed to incorporate the allergen-based formulation, which included a tailor-made vehicle to enhance allergen penetration into the skin. The primary efficacy outcomes were the owner-assessed pruritus manifestations (PVAS10), veterinarian-assessed skin lesions (2D-IGA), and the owner’s perceived treatment efficacy (OGATE and OGES). Secondary efficacy outcomes were the quality-of-life (QoL), sIgE and IL 10 concentrations. The EPIT safety evaluation considered both local and systemic adverse reactions. Treatment efficacy was defined by the primary outcome measures’ success, according to the ICADA’s COSCAD’18 recommendations. EPIT was deemed safe if no severe local and systemic side-effects occurred. The owner’s compliance with the proposed protocol and required study appointments were monitored and their overall satisfaction was estimated. One LR dog dropped out. All dogs improved their pruritus scores, and 13/15 dogs (86.67%) were successful in the terms considered for this study [FB=8/9 (88.89%); LR=5/6 (83.33%)]. Moreover, 8/12 dogs [66.67%; FB=5/8 (62.5%); LR=3/4 (75%)] reached the level considered successful in the skin lesions’ sore. The response to EPIT was rated as good-to-excellent by 13/15 owners (86.67%) in the OGATE survey and by 11/15 owners (73.33%) in the OGES survey. An improvement in the QoL scores was reported by 13/15 owners (86.67%), with a percentage mean improvement of 54.58%. sIgE values overall decreased in 10/15 dogs (66.67%) and 2/15 dogs (13.33%) desensitised to all HDM to which they were previously allergic. Non-conclusive IL-10 results were obtained. No systemic or local severe adverse events were recorded. EPIT was well received by the owners of the 15 dogs, who fully complied with the proposed protocol. This pilot study emphasizes the EPIT’s great potential as an effective and safe CAD treatment, supporting further investigation on this novel therapy.
RESUMO - Imunoterapia epicutânea como uma nova via de administração de alergénios em cães com dermatite atópica : uma prova de conceito - A imunoterapia com alergénios é um tratamento bem estabelecido para a dermatite atópica canina (CAD), mas são necessárias novas vias não invasivas, seguras, eficazes e de fácil administração em casa que promovam a adesão à terapia. A imunoterapia epicutânea (EPIT) é uma via promissora que beneficia da grande acessibilidade e das características imunológicas únicas da pele. O objetivo deste estudo foi avaliar a praticabilidade, eficácia e segurança da EPIT na CAD. Foram recrutados dezasseis cães (9 cães bouledogue francês (FB) e 7 labrador retriever (LR)) com CAD espontânea não sazonal e com serologia de IgE alergénio-específica (sIgE) positiva para ácaros domésticos (HDM) para a aplicação semanal de um penso de 12 horas, durante 12 semanas. Para o efeito foi impresso um dispositivo em 3D para incorporar a formulação alergénica, a qual incluía um veículo desenvolvido para aumentar a penetração dos alergénios na pele. A avaliação da eficácia utilizou parâmetros primários – a avaliação do prurido pelo titular do cão (PVAS10), das lesões cutâneas pelo veterinário (2D-IGA) e a perceção dos titulares sobre a eficácia da terapêutica (OGATE e OGES) – e parâmetros secundários – grau de qualidade de vida e concentrações de sIgE e IL-10. Para a avaliação da segurança foram consideradas reações sistémicas e locais. A eficácia da EPIT foi definida pelo sucesso dos parâmetros primários, de acordo com as recomendações COSCAD’18 do ICADA. A EPIT foi considerada segura se não ocorressem reações sistémicas ou locais graves. Foram ainda registados o cumprimento do protocolo, a comparência dos titulares às consultas do estudo e a sua satisfação global com o tratamento. Um titular de LR desistiu do estudo. Todos os cães melhoraram o grau de prurido, dos quais 13 (86.67%) alcançaram o nível considerado de sucesso [FB=8/9 (88.89%); LR=5/6 (83.33%)]. Além disso, 8 dos 12 cães [66.67%; FB=5/8 (62.5%); LR=3/4 (75%)] alcançaram o nível considerado de sucesso no parâmetro de lesões cutâneas. A resposta à EPIT foi classificada como boa-a-excelente por 13 titulares (86.67%) no OGATE e por 11 titulares (73.33%) no OGES. Verificou-se ainda uma melhoria da qualidade de vida em 13 cães (86,67%), com uma melhoria percentual média de 54.58%. Os valores de sIgE diminuíram globalmente em 10 cães (66.67%) e 2 deles (13.33%) dessensibilizaram a todos os HDM aos quais eram alérgicos. Os resultados da IL-10 foram inconclusivos. Não se verificaram quaisquer reações sistémicas nem locais graves. A EPIT foi bem recebida pelos titulares dos 15 cães, os quais cumpriram criteriosamente o protocolo. Este estudo piloto destaca o potencial da EPIT como um tratamento eficaz e seguro para a CAD e encoraja a investigação futura nesta nova terapia.

Full textThe aim of this work was to study the effects of endotoxin during sensitization with Blomia tropicalis extract (Bt). To induce experimental allergic airways, mice were sensitized s.c. with Bt with or without LPS co-adsorbed onto alum, and challenged i.n. with Bt. Wild type mice sensitized and challenged with HDM showed eosinophilic lung inflammation, Arway hyperactivity (AHR), mucus hyperproduction, increased levels of type 2 cytokines in the bronchoalveolar lavage (BAL) fluid, and augmented total IgE. When LPS was added at the sensitization, we observed an inhibition of eosinophil influx and an increase in neutrophil counts in the BAL. Moreover, LPS inhibited IL-4 and IL-5 production and increased IFN-g and IL-17 production. Surprisingly, LPS did not affect AHR or IgE production. Using knockout mice, we found that the eosinophilic inhibition induced by LPS was dependent on IFNg and MyD88, while the neutrophilic increase was independent of IFNg and dependent on TLR2, TLR4 and CD14 signaling. Moreover, in the absence of TLR2, TLR4 or CD14, LPS suppressed AAD. In conclusion, our results indicate that mice sensitized with Bt and LPS co-adsorbed to alum develop a non-classical asthma-like phenotype that is dependent on TLR signaling.

Thesis, Halmstad University, School of Social and Health Sciences (HOS), 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:hh:diva-3722.
Full textTuberkulos (tbc) är en luftburen droppsmitta orsakad av mykobakterium tuberkulosis. Tbc är den sjukdom som efter AIDS orsakar flest dödsfall, trots att botande behandling finns. Behandlingen är krävande för den tbc-smittade att genomgå och bygger på en kombination av en rad antibiotika som måste intas under minst sex månader. Ett avvikande i behandlingen kan resultera i att mykobakterium tuberkulosis blir resistent mot de ordinerade antibiotika. Följsamhet av långtidsbehandlingar som tbc-behandling graderas till 50 %. Syftet med litteraturstudien var att ur ett globalt perspektiv beskriva hur sjuksköterskan kan påverka följsamhet vid tbc-behandling i syfte att minska resistensutvecklingen av mykobakterium tuberkulosis. Studien genomfördes som en litteraturstudie där 12 vetenskapliga artiklar granskades och analyserades. Resultatet visar tydligt att specifika faktorer påverkar följsamhet och därigenom resistensutvecklingen. Faktorerna innefattar patientundervisning, behandlingsstrategier, omgivningens påverkan och stöd. Undervisningen resulterar i att patienten får ökad förståelse för behandlingen. För att minska stigmatiseringen och det lidande den innebär för den tbc-smittade är även omgivningen i behov av ökad kunskap och information om tbc. Ett flertal studier visar att DOTS-strategin är betydelsefull för ökad följsamhet vid antituberkulos behandling. Litteraturstudien medför ett förslag om att sjuksköterskeprogrammet ska öka fokuseringen på följsamhet vid läkemedelsanvändning. Sjuksköterskan är i behov av att redan under grundutbildningen få kunskap om ansvarsfull antibiotikahantering som leder till en följsamhetsomtanke.
Tuberculosis (TB) is an airborne droplet infection caused by mycobacterium tuberculosis. TB is the disease after AIDS that is most deadly, even though curative treatment exists. The treatment is demanding for the TB-infected to undergo and consists of a combination of a number of antibiotics that must be administered for at least six months. A dissenting in anti-tuberculosis treatment might result in mycobacterium tuberculosis strains that are resistant to antibiotics. As adherence to long-term treatment is graded at a low percentage (50 %) the aim of the literature study was from a global perspective to develop a working-strategy for nurses that promote compliance in TB-treatment in order to reduce resistance development of mycobacterium tuberculosis. The study was conducted as a literature study where 12 research articles were reviewed and analyzed. The results describe specific factors that are essential to compliance. These factors comprise patient education, treatment strategies, social influences and support. As knowledge gives the patient a better understanding for the treatment it provokes compliance. The social environment of the TB-infected patient demands increased knowledge in order to reduce stigma. Several studies show that the DOTS strategy is important for increasing compliance in anti-tuberculosis treatment. The literature study results in a proposal for the nursing program to focus more on compliance in taking medication. The nursing program’s attendants need to gain knowledge about prudent antibiotic treatment that leads to a compliance concern.

Full textA dermatite atópica canina (DAc) é uma doença de incidência elevada e crescente na população canina. A par da evicção alergénica, frequentemente inviável, a imunoterapia alergénio-específica (ITAE) é o único tratamento passível de modificar o curso natural da doença a longo prazo, mesmo após a sua suspensão. A via de administração tradicional de ITAE é a injeção subcutânea; no entanto, a via sublingual (SLIT) tem vindo a ganhar cada vez mais adeptos na comunidade médica devido à sua proclamada maior segurança, praticabilidade e conforto na aplicação. O principal objetivo deste estudo retrospetivo centrou-se na avaliação da eficácia de um protocolo inicial de 7 meses de SLIT em 22 canídeos atópicos. Numa primeira fase procedeu-se a análise epidemiológica dos painéis alérgicos de 72 canídeos diagnosticados clinicamente com DAc e submetidos a provas alergológicas serológicas. Destes, 16,7% resultaram num painel alérgico negativo a todos os aeroalergénios testados. Na amostra analisada não houve predomínio de género e a raça indeterminada e o Retriever do Labrador foram as mais prevalentes. O grupo de alergénios mais frequentemente envolvido no processo alérgico foi o dos ácaros, nomeadamente as espécies Dermatophagoides farinae, Acarus siro e Tyrophagus putrescentiae. Na segunda fase, analisou-se a resposta à terapêutica em 22 canídeos atópicos submetidos a um protocolo de 7 meses de SLIT, face a um grupo de controlo de 22 canídeos atópicos tratados exclusivamente com medicação antialérgica sintomática. Esta análise foi feita através de um questionário aplicado aos donos dos animais e através do grau de redução da necessidade de medicação antialérgica concomitante para controlo dos sinais clínicos de DAc. Obteve-se uma redução estatisticamente significativa dos níveis de prurido no grupo de estudo face ao grupo de controlo. Ainda, 31,8% dos animais conseguiram controlar os sinais clínicos de DAc com recurso apenas à SLIT ou, em alguns casos, combinada com champô hipoalergénico. De forma geral, 86,4% dos animais responderam positivamente ao tratamento com SLIT. No entanto, o período de 7 meses de tratamento foi insuficiente para prevenir recidivas após a suspensão, pelo que o mesmo deve ser alargado. Este estudo, apesar das suas limitações, contribui assim para o crescente volume de bibliografia que atesta a eficácia e segurança da SLIT, constituindo uma alternativa válida para o tratamento da DAc.
ABSTRACT - Results of a sublingual allergenic-specific immunotherapy protocol in atopic dogs in Oeiras, Portugal: a pilot study - Canine atopic dermatitis (cAD) is a disease with a high and increasing incidence in the canine population. Only allergenic avoidance, which is frequently not viable, and allergenspecific immunotherapy (ASIT) can affect the natural course of allergic diseases, even after treatment interruption. Subcutaneous injections are the traditional route of ASIT administration; however the medical community’s interest in sublingual administration (SLIT) is growing due to its high safety profile, practicability and more comfortable administration. The main purpose of this retrospective study was to evaluate the response to a 7-month SLIT protocol executed upon 22 atopic dogs. Initially (stage 1), we conducted an epidemiological analysis on the allergenic results of 72 dogs diagnosed with cAD, both clinically and through serological testing. From these, 16,7% had negative results to all allergens tested. In our sample, no sex predisposition was found, plus crossbreed dogs and Labrador retrievers were the most frequently affected out of the sample. Mites constituted the group of allergens mostly involved in the allergic pathway, specifically Dermatophagoides farinae, Acarus siro and Tyrophagus putrescentiae. In a second stage, we analyzed the treatment response of 22 atopic dogs that endured a 7- month SLIT protocol in comparison to a control group of 22 atopic dogs submitted only to an anti-allergic symptomatic drug treatment. This analysis was conducted using questionnaires presented to the dog’s owners and through the medical records, which allowed us to evaluate the need for anti-allergic medication in order to control the pruritus. We observed a significant statistical reduction in the level of pruritus in the study group, compared to the control group. Furthermore, in 31,8% of the dogs it was possible to control the clinical signs merely using SLIT or, in some cases, SLIT combined with a hypoallergenic shampoo. Overall, 86,4% of the dogs positively responded to SLIT. However, we concluded that the 7- month treatment period is not enough to prevent relapses after SLIT’s discontinuation and, therefore, the period of treatment should be longer. Despite the limitations, this study contributes to the growing body of evidence that supports the efficacy and safety of SLIT and considers it a viable alternative treatment in AD patients.

Full textEmbora raramente se associem com complicações graves, as rinossinusopatias acarretam grande morbidade, absenteísmo laboral e escolar e grande custo financeiro. Em nível local, há poucos estudos clínicos descritivos sobre manifestações clínicas, otimização de métodos e critérios diagnósticos e sobre o perfil de comorbidade segundo a etiopatogênese (estrutural, funcional, alérgica ou infecciosa). Objetivo: descrever comparativamente os achados clínicos, do transporte mucociliar, citopatológicos, do teste cutâneo para alérgenos, endoscópicos e imaginológicos. Casuística e métodos: 212 casos recrutados dentre 2549 pacientes atendidos no Hospital da Polícia Militar e no Centro de Otorrinolaringológico, em Vitória, ES, entre 3 de janeiro de 2005 e 11 de maio de 2006; 10 tabagistas e 10 não tabagistas sem queixas rinossinusais foram adicionalmente recrutados para comparação. Os achados foram sumarizados como freqüências absoluta e relativa simples de acordo com o grupo etiopatogênico. Resultados: anormalidade estrutural foi identificada em 10 (4,7%), funcional em 11 (5,2%), alérgica em 28 (13,2%), infecciosa em 13 (6,1%), mais de uma das precedentes em 136 (64,1%) e outras doenças em 14 (6,6%). Dentre as 612 comparações analisadas, 19% mostraram freqüência com incremento direto maior que 20% entre os grupos: rinossinusite, rinite alérgica, anormalidade anatômica e funcional. Conclusão: estes resultados demonstram que a comorbidade é a regra e os achados, similares e sobrepostos entre as várias rinossinusopatias, demandam, para a sua distinção, a consideração concomitante dos aportes da história clínica, citopatologia, transporte mucociliar, endoscopia nasal e imaginologia.
Rhinosinusal illnesses are associated with a great morbidity, high costs for the patients and high tax of labor and school absenteeism. Even though these illnesses are well known, there is few descriptive studies about the clinical manifestations, the optimization of the diagnostic criteria and the distribution of comorbidity according to the etiopathogenic types (structural, functional, allergic and infectious) at a local level. Objective: to carry through a comparative description of the clinical, mucociliary clearance, citopathologic, endoscopic and imaginologic findings of the rhinosinusal illness at local doctors office. Patients and methods: 232 of a universe of 2549 patients taken care at two otorrhinolaringologic clinics at Vitória citty, Espírito Santo State, Brazil, from January, 3rd of 2005 to May, 11th of 2006. Of 232, 212 were patients with some rhinosinusal complaints and 20 citizens without rhinosinusal complaints (10 smokers and 10 nonsmokers) were used as control group. The absolute and relative frequency of clinical and laboratory findings were compared between the ethiopathogenic types of rhinosinusal illness. Results: structural abnormalities was present in 10 (4,7%), functional abnormalities in 11 (5,2%), allergy in 28 (13,2%) and infection in 13 (6,1%); in 136 (64,1%) there is more than one of these conditions. Among the 612 findings analised, 19% shows direct increment of frequency higher than 20% between the rhinosinusal types: rhinosinusitis, allergic rhinitis, structural and functional abnormalities. Conclusion: these results show that comorbidity is high and that there is great overlapping of findings between the various types of rhinosinusal illness. To discriminate between them is necessary to take account of concommitant contribution of the clinical history, cytopathology, mucociliary clearance, endoscopic and imaginologic findings.

Full textHaptens are endowed with pro-inflammatory and antigenic properties responsible for activation of both innate and acquired immunity leading to irritant and allergic contact dermatitis, respectively. Although it has been established that the frequency with which individuals develop allergic contact dermatitis directly correlates with the pro-inflammatory properties of haptens, the pathophysiological mechanisms linking irritancy and allergy are still not known precisely. In the first part of the thesis, we show that the development and severity of allergic contact dermatitis depends on the ability of haptens to deliver non specific inflammatory signals during sensitization, leading to: i) irritant contact dermatitis, ii) recruitment of dendritic cell precursors into the skin, iii) migration rate of dendritic cells to the lymph nodes where T cell activation occurs and, iv) T cell recruitment into the skin. The second part of this work concerns the study of the role of Toll-like receptor-2 (TLR-2), an innate immune receptor, in the development of allergic contact dermatitis. We demonstrate that the absence of TLR-2 in sensitized mice leads to an exacerbate allergic contact dermatitis, indicating that TLR-2 is involved in the down-regulation of the skin inflammation. Collectively, our results demonstrate that irritancy conditions the magnitude of allergic responses. Therefore, molecules able to decrease the pro-inflammatory properties of haptens could be new preventive or curative treatments of both irritant and allergic contact dermatitis

Full textThe goal of this study was to elucidate which of the soy protein fractions is more allergenic by using enzyme immunoassays and passive cutaneous anaphylactic activity test. Furthermore, monoclonal antibodies were obtained in order to standardize immunoassays to detect soy protein fractions in commercial soy-derived products. Purification of 2S, 7S and 11S fractions from soy was based on previous studies which were adapted to our experimental conditions. Purity of the isolated fractions was determined by polyacrilamide gel electrophoresis (7-15%). The subunits α (63,17 KDa) α\' (58,06 KDa) and β (42,09 KDa), corresponding to 7S fraction as well as the acid (38,8 KDa) and basic (21,04 Kda) subunits of 11S fraction were visualized. The 2S fraction showed a 20 KDa band only. Data showed that the 7S and 11S soy fractions are immunogenic as they elicited IgM and IgG antibodies in BALB/c mice. In contrast, the 2S fraction was not immunogenic in this specie. The passive cutaneous anaphylactic activity test showed that 7S fraction is allergenic as it elicited IgE production in BALC mice. However, this test was negative for 2S and 7S fractions. No IgE reactive against the 2S, 7S e 11S was found in sera of patients (n=5) presenting previous food allergy symptoms. However, either these patients or controls (n=5) showed IgG reactive against 2S and 7S fractions in their sera. The four monoclonal antibodies obtained in this study were reactive up to 1/8000 (2A8 and 1H4) and 1/10000 (1F9) against 7S fraction, and up to 1/12000 (3F2) for 11S fraction. Immunoblot analysis showed that the monoclonal antibodies anti-7S fraction (1H4, 2A8 e 1F9) recognized the α α\' and β (1F9), α\' and β (1H4) and α (2A8) subunits. The monoclonal antibody anti-11S fraction (3F2) reacted with the basic subunit of this fraction only. By using ELISA and the monoclonal antibodies anti-7S and anti-11S it was possible to detect especifically these soy protein fractions in commercial soy-derived products. In conclusion, data suggest that 7S and 11S soy protein fractions are immunogenic in mice while 2S and 7S fraction are immunogenic in humans. The IgE response to 7S fraction in BALB/c mice showed by the passive cutaneous anaphylactic activity test indicates that this soy protein fraction is allergenic in this experimental model. Finally, the monoclonal antibodies anti-7S and anti-11S obtained in this study did not react with other vegetable or animal proteins being suitable to be used in ELISA for detection of these proteins in commercial soy-derived products.

Full textUsing model of coinfection allergy and tuberculosis (TB / OVA), our group showed that coinfected BALB/c showed a significant decrease in the number of bacilli, associated with a decrease in granulomatous infiltrate the lung, increased production of leukotriene B4 and the number of cells CD8+, compared to the group infected with Mycobacterium tuberculosis (TB). To evaluate the mechanisms involved in reducing the growth of bacilli in group TB/OVA, were used four strategies: I) To assess the role of CD8+ lymphocytes in model TB/OVA, we used mice deficient for the molecule CD8 (CD8KO).We was observed that the number of bacilli in the lungs of animals in the group CD8KO-TB/OVA and WT-TB/OVA was similar. However, the lungs of animals WT-TB/OVA growth of bacillus was higher compared to WT animals, TB, unlike what was previously observed with background genetic BALB/c. To evaluate the role of leukotrienes, we use the following strategies: II) strain 129Sv mice treated with MK886, an inhibitor of the enzyme 5-lipoxygenase (5LO), involved in the synthesis of lipid mediators, III) 129Sv animals deficient for the expression of 5LO (5LOKO). We observed that treatment with MK886 did not affect the number of bacilli in the lung of the coinfected group TB/OVA. Moreover, unlike what was previously observed in animals BALB/c mice, coinfected 129Sv were more susceptible than the animals infected 129Sv. On the contrary, 5LOKO-TB/OVA animals were more resistant than mice WT-TB/OVA. To assess whether changes in granulomatous infiltrates were related to macrophages, we use the fourth strategy: IV) quantification of macrophage populations M1 and M2. We observed that M2 population in animals TB/OVA showed increased lung. The decrease in bacilli growth of animals TB/OVA was dependent on macrophage M2, since animals deficient for the expression of IL-33 protocol submitted to coinfected protocol had decreased macrophage population M2, and were susceptible to infection. These results show that the reduction in growth of bacilli in coinfected animals TB/OVA is dependent increase in macrophage population M2.

Full textAn increased prevalence of asthma and allergic symptoms, exercise-induced bronchoconstriction (EIB) and bronchial hyperresponsiveness (BHR) has been observed in elite and endurance athletes, especially winter sports athletes and swimmers. However, the occurrence of allergy symptoms and the inflammatory mechanisms involved in the EIB that occurs in long distance runners remains poorly known. Objectives: the aims of the present study were to assess the prevalence of symptoms of asthma and allergy in long distance runners and to investigate possible inflammatory mediators involved in the EIB that occurs in those without asthma history. Methods: This cross sectional study was performed in two phases. In Phase I, the prevalence of symptoms of asthma and allergy was assessed in 201 long distance runners using ISAAC and AQUA© questionnaires. In Phase II, 40 athletes were randomly selected among those who did not present asthma history and they performed the following measurements: induced sputum, cardiopulmonary exercise testing, methacholine bronchoprovocation challenge, exhaled nitric oxide (FeNO), urinary collection to quantify LTE4 and 9alfa, 11beta-PGF2 metabolites and eucapnic voluntary hyperventilation test (EVH). Results: The prevalence of asthma and allergy symptoms was 6.5% and 60.5%, respectively. In addition, we observed a high frequency of EIB symptoms (62.3%) and rhinitis (56.6%). Allergy symptoms were not associated with anthropometric characteristics, running experience, weekly training volume and best half-marathon and marathon performance. The prevalence of EIB was 27.5% and no difference in baseline lung function, anthropometric data as well as training and performance characteristics was observed between athletes with (EIB+) and without (EIB-) EIB. EIB+ athletes reported more allergy symptoms (p=0.03) and were more resposive to methacholine (p=0.01) than EIB- athletes. A higher percentage of eosinophils in the induced sputum (p=0.03) and levels of FeNO (p < 0.001*) were observed in EIB+ athletes. However, there was no difference in the urinary levels of LTE4 and 9alfa, 11beta-PGF2 either at baseline or after EVH test. Conclusions: Long distance runners have a high prevalence of allergy symptoms and EIB and a low prevalence of asthma symptoms. Moreover, EIB+ athletes report more symptoms of allergy and present airway hyperresponsiveness, eosinophilic inflammation and increased levels of exhaled nitric oxide, without difference in the baseline levels of mast cell metabolites

Full textA dermatite atópica canina (cDA) é a doença atópica mais frequentemente diagnosticada no cão e pensa-se que o número de casos seja cada vez maior. A imunoterapia específica para alergénios (ITAE) consiste na administração de quantidades, gradualmente crescentes, de um alergénio, de forma a atenuar os sinais clínicos de cDA. A fim de se alcançar uma maior eficácia, esta terapêutica deve ser ajustada para cada caso. Assim, a escolha dos alergénios a incluir e do protocolo a seguir deve ser criteriosamente efectuada, tendo em conta a história clínica, o ambiente e a reacção individual de cada paciente. Este estudo teve como objectivo caracterizar a utilização da ITAE por parte dos Médicos Veterinários (MV) e tentar esclarecer se os conceitos acima descritos são aplicados na prática clínica corrente. Pretendeu-se também avaliar os proprietários dos pacientes alérgicos em relação aos seus conhecimentos sobre a ITAE e à vontade que demonstraram em aderir a esta terapêutica. No caso dos proprietários de animais que já realizaram ITAE durante um período mínimo de 6 meses, analisou-se o seu grau de satisfação com o tratamento. Para tal, foram realizados inquéritos a MVs, a proprietários de animais com cDA e a proprietários de animais que já realizaram ITAE. Concluiu-se que o conceito de ajustamento da ITAE a cada paciente não se encontra ainda bem esclarecido na classe Médico Veterinária. De facto, a maioria dos MVs não opta por ajustar o protocolo de administração e elegem os alergénios a incluir no tratamento exclusivamente com base nos resultados positivos das provas alergológicas. Os proprietários de pacientes com cDA têm uma opinião positiva sobre a ITAE e estão dispostos a aderir a esta. O nível de informação e de satisfação dos proprietários cujos animais já foram submetidos a este tratamento é elevado. Verificaram-se, assim, algumas lacunas na utilização da ITAE, pelo que se sugere que haja uma maior educação dos MVs sobre os aspectos práticos desta terapêutica, uma vez que estes se reflectem directamente na sua eficácia, sendo no entanto pouco valorizados pela generalidade dos clínicos. É também importante apostar na informação dos proprietários, com o intuito de aumentar a cooperação por parte destes e de obter melhores resultados clínicos.
ABSTRACT - Allergen specific immunotherapy as a treatment of canine atopic dermatitis – present situation of Veterinarian´s and owner´s knowledge on the subject - Canine atopic dermatitis is the most frequently diagnosed atopic disease in dogs and it seems to be increasing in the canine population. Allergen specific immunotherapy is based on the administration of gradually increasing doses of allergens, with the purpose of alleviating the clinical signs of canine atopic dermatitis. In order to achieve a greater effectiveness, this treatment should be tailored individually to each patient. Therefore, the allergens included and the protocol followed should be chosen carefully, taking into account the medical history, the environment and the individual reaction of each animal. The objective of this study was to analyze the use of immunotherapy by Veterinary clinicians and to verify if the above criteria are applied in current clinical practice. We also evaluated how much owners of allergic dogs know about this treatment and how willing they are to adhere to it. In those owners whose dogs had been submitted to immunotherapy for a period of at least six months, we wanted to know if they were satisfied with this treatment. Therefore, surveys were carried out to Veterinarians and owners of dogs which suffer from atopic dermatitis and which have undergone specific immunotherapy. We conclude that immunotherapy is not being individualized to each patient by most clinicians. In most cases the choice of the allergens is based on the positive titles of the serum-based tests, regardless of seasonality of clinical signs. The owners of dogs with atopic dermatitis have a good opinion of immunotherapy and are willing to adhere to it. Also the owners of dogs that have done this treatment demonstrated high levels of information and satisfaction. It is suggested that Veterinarians should pursue higher levels of education regarding the practical aspects of immunotherapy, which reflect on its effectiveness and are nonetheless not being taken into account in clinical practice. . It is also suggested to invest in the information of the owners as we also believe that client education is paramount to increase their cooperation and achieve better clinical results.

As afecções do sistema respiratório são a segunda causa de queda de desempenho e afastamento dos equinos do esporte ou trabalho, as quais estão atrás somente das desordens musculoesqueléticas. A estabulação e alimentação a base de fenos predispõe os equinos a inalação de grande número de agentes irritantes as vias aéreas. No intuito de mensurar a influência dos tipos de cama utilizado em baias de equinos nas respostas alérgicas das vias aéreas estudou-se 3 grupos com 5 equinos cada sendo dois mantidos em cocheiras com diferentes tipos de forração à base de madeira (maravalha de pinus autoclavada-MA e serragem-SE) e por último um grupo controle à pasto por 45 dias com avaliações quinzenais (D0, D15, D30 e D45). Foi realizado nestes momentos o exame físico, coleta de amostras de sangue venoso e arterial para realização de hemograma e hemogasometria respectivamente, lavado broncoalveolar com análise citológica e mensuração de fosfatase alcalina, além de amostras das camas (limpa e suja) e feno pré-secado para análise micológica. No exame físico foi notado tosse e espirros em maior intensidade e número nos equinos do grupo SE. A análise hematológica permaneceu dentro dos padrões de normalidade. Já nos achados hemogasométricos os maiores valores de pH foram observados nos equinos à pasto (7,47 ± 0,02). Nos grupos embaiados foi observado valores de pressão parcial de dióxido, de D15 à D45, inferiores (valores entre 38,3 a 43,7 mmHg) ao grupo a pasto (valores entre 43,7 a 46,5 mmHg), sendo os valores de pressão parcial de oxigênio inversamente proporcionais (MA e SE: valores entre 103,6 a 127,78 mmHg e à pasto: 88,2 a 103,6 mmHg). Os principais achados no lavado broncoalveolar basearam-se na contagem de células nucleadas totais no que apresentou maiores valores em todos os momentos nos animais à pasto (251,0 a 336,8 x 103/ µL), seguido do grupo SE (197,0 a 248,6 x 103/ µL) e por último o MA (140,6 à 270,2 x 103/ µL). Dentre as células nucleadas os macrófagos representaram maior porcentagem seguidos dos linfócitos (51,2 a 80,8% e 6,6 a 33,2% respectivamente). Um padrão inesperado foi observado na população de neutrófilos, os quais com os passar dos momentos houve decréscimo, com excessão do grupo MA que apresentou um pico no D30 (35%), relacionado ao pico de fosfatase alcalina (27,6 ± 14,98 UI/L) neste mesmo momento. Foram identificados cerca de 12 gêneros fúngicos em ambas camas e 17 no alimento volumoso, sendo neste último encontrado gêneros patogênicos como Aspergillus (0,85 ± 2,2%), Fusarium (5,35 ± 9,23%) e Penicílium (4,81 ± 9,53%), porém em baixas porcentagens. A principal diferença entre as camas baseou-se na capacidade da produção e dispersão de partículas finas passíveis de inalação, a qual foi maior para a serragem (MA: 15,29 % e SE: 18,28%). Concluiu-se que a cama de maravalha além de ter manejo mais fácil, apresentou menor capacidade irritativa das vias aéreas superiores do que a serragem. As condições de manejo e estabulações utilizadas foram ideais, servindo de modelo quanto a ventilação e higienização das baias.
Horse respiratory diseases is second most commom cause of poor performance and premature retirement, which the one are musculoskeletal disorders. The stabling and poor quality feedings may the favor predispose of diseases in airways. In order we measure the influence of the types of bedding used in the horse stalls about responses allergic airway. Three groups of five horses each are formated, two groups kept in stables but each group with a different type of bedding (autoclaved wood- MA shaving and sawdust-SE) . The third group is the control and stays at pasture. The groups remained in this condition for 45 days with biweekly reviews (D0, D15, D30 and D45). It was realize the physical examination, venous and arterial blood samples collection to realize hemogram and hemogasometry analysis, the bronchoalveolar lavage samples was colected to realize the cytological analysis and to measure alkaline phosphatase. In addition, samples of the beds (clean and dirty) and haylage was collected to realize mycological analysis. In the physical examination was noticed higher intensity of coughing and sneezing at SE group. Hematological analysis remained within the normal standards. Findings of hemogasometric analysis were observed the biggest pH values at horses to pasture (7.47 ± 0.02). At stables horses was observed smaller values of partial pressure dioxide (D15 to D45), (values between 38.3 to 43.7 mmHg) to horses to pasture (values between 43.7 to 46.5 mmHg). The values oxygen partial pressure it was inversely proportional to partial pressure dioxide (MA and SE: values between 103.6 to 127.78 mmHg and pasture: 88.2 to 103.6 mmHg). It was observate higher values of nucleated cells of bronchoalveolar lavage, at all times, in animals to pasture (251.0 to 336.8 x 103 / mL), followed by the SE group (197.0 to 248.6 x 103 / mL) and finally MA group (140.6 to 270.2 x 103 / mL). The macrophages cells represented the biggest percentage of nucleates cells on bronchoalveolar lavage followed by lymphocytes (51.2 to 80.8% and 6.6 to 33.2% respectively). An unexpected pattern was observed in percentange of neutrophils cells, that it was a decrease over the time. One exception it was with MA group that had the biggest percentage values in D30 (35%), it was related to alkaline phosphatase peak at same time (27.6 ± 14.98 IU / L). Were identified about 12 fungi genres in both beds and 17 fungi genres at haylage. We indentified pathogenic genres in haylage as Aspergillus (0.85 ± 2.2%), Fusarium (5.35 ± 9.23%) and Penicillium (4 , 81 ± 9.53%), however in lower percentages. It was observate a difference production capacity and fine particle dispersion between the bed, that the biggest it was notice at sawdust (MA: 15.29% and SE: 18.28%). It was concluded that wood shavings bed is easier to use and showed less irritative capacity upper airway to que sawdust. As management and stabling conditions used were ideals and it was a ideal model of stables.

Resumo: Diversos estudos descrevem o perfil clínico-epidemiológico e os resultados dos testes de contato das populações atendidas com suspeitas de dermatite alérgica de contato. Alguns evidenciam a provável relação causal com o trabalho; outros alertam para a necessidade de repetição do teste quando ocorrem múltiplas reações, principalmente nas demandas trabalhistas. O objetivo foi analisar o perfil clínico-epidemiológico e os resultados dos testes de contato dos pacientes com suspeita de dermatite alérgica de contato ocupacional atendidos no Ambulatório de Medicina do Trabalho da Universidade Estadual de Campinas. Foi realizado um estudo descritivo transversal retrospectivo com pacientes atendidos entre 1 de janeiro de 1999 e 31 de dezembro de 2008, envolvendo as seguintes variáveis: idade, cor, sexo, ocupação, tempo na ocupação, agente referido como sensibilizante, local inicial do eczema, origem do encaminhamento, resultados dos testes de contato e nexo causal. Foram analisados 180 prontuários e os resultados mostraram que o perfil clínicoepidemiológico foi semelhante àqueles referidos na literatura, mas os índices desensibilização foram proporcionalmente maiores: 85% dos pacientes tiveram pelo menos uma reação positiva no primeiro teste de contato, a média de reações positivas por teste foi 3,38 e 68% dos testes positivos apresentaram mais de duas reações positivas. Os elevados índices de sensibilização e a existência simultânea de múltiplas reações na maioria dos pacientes podem ser explicados por condições predisponentes para polissensibilização - dermatite nas mãos cronificadas por repetidas exposições ocupacionais - e/ou pela interpretação de reações irritativas como reações positivas. Foi sugerida, então, uma Ficha de Coleta de Dados, a ser preenchida durante as avaliações clínicas e a repetição dos testes de contato quando ocorrerem mais de 2 reações positivas relevantes a substâncias não correlacionada
Abstract: Several studies describe the clinical and epidemiological profile and the results of patch tests of the targeted population with suspected allergic contact dermatitis. Some evidence the probable causal relationship to work; others warn of the need to repeat tests when multiple reactions occur, especially in the lawsuits. The objetive was to analyze the clinical and epidemiological profile and the results of patch tests of patients with suspected allergic contact dermatitis treated at the Campinas State University's Occupational Medicine Clinic. We conducted a retrospective cross-sectional study with patients treated between January 1, 1999 and December 31, 2008 involving the following variables: age, race, sex, occupation, time in occupation, sensitizing agent, eczema locus, referral source, results of patch tests and causal relationship. We analyzed 180 medical records and the results show that clinical and epidemiological profile was similar to those reported in the literature, but the rates of awareness were proportionally larger: 85% of patients had at least one positive reaction in the first patch test, the average of positive reactions per test was 3.38 and 68% dos positive tests had more than two positive reactions. High levels of sensitization and the simultaneous existence of multiple reactions in most patients can be explained by predisposing factors to polysensization - cronic dermatitis on the hands caused by repeated occupational exposure - and/or by the interpretation of irritant reactions as positive reactions. It has been suggested then a sheet data collection to use in the clinic evaluation that includes the repetition of tests when more than 2 relevant positive reactions occurred to substances not correlated

Root bark infusions of the plant Cissampelos sympodialis Eichl (Menispermaceae) are used in folk medicine, in Northeast Brazil, for the treatment of diseases of the respiratory and digestive tracts. Previous studies showed that the hydroalcoholic extract of the leaves (AFL) of the plant and warifteine (W), alkaloid bisbenzylisoquinolinic, presented anti-inflammatory and anti-allergic effects. This study evaluated the effect of the oral treatment of mice with W and methyl warifteine (MW) in the paw edema formation induced by phlogistic agents, vascular leakage and cell migration in acute inflammatory models and the effect of oral treatment with AFL and its alkaloids (W and MW) in chronic inflammation represented by the experimental model of food allergy (BALB / c mice sensitized with ovalbumin - OVA). Oral treatment with W reduced the paw edema induced by carrageenan, histamine and prostaglandin E2, an effect not presented in MW treatment. The warifteine and methyl-warifteine also reduced the vascular leakage, however without inhibiting cell migration associated with inflammation. In the experimental model of food allergy the treatment with W induced weight gain in animals with decreased of diarrhea. Methylation of warifteine did not induce weight gain nor inhibited allergic diarrhea during the allergen challenge. However treatment with AFL did not induce weight gain nor inhibited allergic diarrhea. In contrast, treatment with the AFL or its alkaloids reduced the IgE specific for ovalbumin (OVA) titer, increased the proportion of CD4 + or CD8+ T lymphocytes in mesenteric lymph nodes. The proportion of regulatory T lymphocytes in the mesenteric lymph nodes was also increased by the treatments. In vitro experiments, with cells from mesenteric lymph nodes of sensitized animals, demonstrated that W and MW inhibited the secretion of interleukin (IL-) 12 and IL-10 with no change in the interferon-γ (IFN-γ) and IL- 13 levels. These results demonstrated that the oral treatment with warifteine presented anti-inflammatory activity by inhibiting the action of mediators of inflammation and the methylation of the molecule did not improve this effect. Also, the treatment with AFL, W and MW showed immunomodulatory effects in food allergy with increased of Treg cells and decreased of cytokines derived from cells of the innate immune mechanism independent of that of the adaptive immune mechanism.
Infusões das raízes da planta Cissampelos sympodialis Eichl (Menispermaceae) são utilizadas, pela medicina popular, no Nordeste Brasileiro, para o tratamento de doenças do trato respiratório e digestório. Estudos prévios demonstram que o extrato hidroalcoólico das folhas (AFL) da planta e a warifteina (W), alcaloide bisbenzilisoquinolínico, apresentam efeitos anti-inflamatórios e antialérgicos. Esse estudo avaliou, portanto, o efeito do tratamento oral de camundongos com W e a metil-warifteina (MW) na formação do edema de pata induzido por agentes flogísticos, no extravasamento vascular e na migração celular em modelos de inflamação aguda e o efeito do tratamento oral com a AFL e seus alcaloides (W e MW) na inflamação crônica representada pelo modelo experimental de alergia alimentar (camundongos BALB/c sensibilizados com ovalbumina - OVA). O tratamento com a W reduziu o edema de pata induzido por carragenina, por histamina ou prostaglandina E2, efeito esse não observado com o tratamento com MW. A warifteina e a metil-warifteina também reduziram o extravasamento vascular, contudo sem inibir a migração celular associada à inflamação. No modelo experimental de alergia alimentar o tratamento com W induziu ganho de peso dos animais com diminuição da diarreia. A metilação da warifteina, embora não tenha induzido o ganho de peso diminuiu a diarreia durante os desafios com o alérgeno. Todavia o tratamento com AFL não induziu o ganho de peso e nem inibiu a diarreia alérgica. Diferentemente, os tratamentos com o AFL e com os alcaloides reduziram os títulos de IgE específica para ovalbumina (OVA), aumentaram a proporção de linfócitos T CD4+ e CD8+ no linfonodo mesentérico. A proporção de linfócitos T reguladores foi aumentada no linfonodo mesentérico pelos tratamentos em estudo. Os experimentos in vitro, com células do linfonodo mesentérico de animais sensibilizados, demonstraram que W e MW inibiram a secreção de interleucina (IL-)12 e IL-10, sem alteração nos níveis de interferon-γ (IFN-γ) e IL-13. Esses resultados demonstraram que o tratamento oral com warifteina apresentou atividade anti-inflamatória por inibir a ação de mediadores da inflamação e que a metilação da molécula não potencializou seu efeito. Também, os tratamentos com AFL, W e MW apresentaram efeitos imunomoduladores na alergia alimentar com aumento de células Treg e com diminuição de citocinas oriundas de células do mecanismo imune inato independente das do mecanismo imune adaptativo.

Full textThis study aim to protect the rights to health and adequate food of the population with food allergy, estimated at about 8% of children and 3% to 5% of adults, arguing there is a need for the provision of information about allergens on product labels, as well as along consumers service assistance (such as electronic websites and phone numbers). It is pointed the interrelationship between the right to health and right to life as well as that between the right to health and the right to adequate food, rights whose effective protection depend on the consumers access to information. The relevance of the topic regarding the right to information about the presence of allergens and feasibility of the proposal of the obligation of allergens labeling are demonstrated through the analysis of existing standards relating to food labeling in Brazil, as well as which treatment given to the issue of labeling of allergens in comparative law. Finally, on the premise that people with food hypersensitivity need to maintain a diet that excludes the presence of allergens, as a way to ensure their well-being and their life with dignity, it is pointed to the State's responsibility to protect the rights to health and to adequate food of this portion of the Brazilian population, with the regulating of the duty of providing information about the presence (or absence) of such substances in food available for consumption for part of the food industry, although this presence give up unintentionally (traces), which depends on compliance with good manufacturing practices for food products and careful risk assessment
Este trabalho objetiva tutelar os direitos à saúde e à alimentação adequada da população com alergia alimentar, estimada em cerca de 8% das crianças e entre 3% e 5% dos adultos, sustentando a necessidade de que haja a disponibilização de informações a respeito de substâncias alérgenas nos rótulos dos produtos, assim como junto aos canais de atendimento ao consumidor (como sítios eletrônicos e telefones). Como fundamentação, aponta para a inter-relação existente entre o direito à saúde e o direito à vida, assim como aquela existente entre o direito à saúde e o direito à alimentação adequada, direitos cuja tutela efetiva dependem do acesso à informação por parte dos consumidores. A relevância do tema, atinente ao direito à informação quanto à presença de alérgenos e a viabilidade da proposta de rotulagem obrigatória, é demonstrada a partir da análise das atuais normas relacionadas à rotulagem de alimentos no Brasil, assim como qual o tratamento conferido ao tema da rotulagem de alérgenos no direito comparado. Por fim, partindo da premissa de que as pessoas com hipersensibilidade alimentar necessitam manter uma dieta que exclua a presença de alérgenos, como forma de se garantir o seu bem-estar e sua existência digna, aponta-se a responsabilidade do Estado em proteger os direitos à saúde e à alimentação adequada desta parcela da população brasileira, através da regulamentação do dever de disponibilização de informações quanto à presença (ou ausência) de tais substâncias nos alimentos disponibilizados ao consumo por parte das indústrias alimentícias, ainda que tal presença se dê de forma involuntária (traços), o que depende da observância de boas práticas de produção de produtos destinados à alimentação e criteriosa avaliação de riscos

Full textIntroduction: It is estimated that 10% of asthma patients have symptoms and important limitations such as frequent exacerbations or persistent reduction of resiratory function, despite the use of corticosteroids. The alterations of distal lung parenchyma have been recently evaluated on asthma pathophysiology, particulary in patients with refractory asthma and difficcult to control. These patients have increased oxidative stress responses, mainly with significant activation of iNOS. Aims: We evaluated the effects of montelukast or dexamethasone treatments associated or not to an iNOS inhibitor (1400W) on eosinophilic response, extracellular matrix remodeling, oxidative stress, actin content, IL4, IL5, MMP9, TIMP1, IFN gama, TGF beta positive cells of distal lung parenchyma in guinea pigs with chronic alergic inflammation. Methods: Guinea Pigs were inhaled with ovalbumin (OVA group) twice a week for four weeks. After 4th inhalation, GP were treated with montelukast (OVAM group-10mg/Kg/PO/day) or dexamethasone (OVAD group-5mg/Kg/IP/day). The treatment with iNOS inhibitor 1400W (OVAW group-1mg/kg/day) was given daily in the last 4 days (OVAW, OVADW and OVAMW groups). After 72 hours of 7th inhalation, GP were anesthetized, lung strips were retired and submitted to histopathological evaluation. Results: There was an increase in eosinophilic infiltrate, in the number of positive cells for IL4, IL5, TIMP1, MMP9, iNOS, IFN gama TGF beta, actin, isoprostane PGF2 alpha, elastic and collagen fiber contents in OVA animals comparing to SAL group (p<0,05). There was a decrease in the number of eosinophils, IL4, IL5, MMP9, TIMP1, IFN gama, TGF beta positive cells, collagen, actin and isoprostane PGF2 alpha content in all treated groups compared to OVA animals (p<0.05), but the treatment with montelukast did not reduce the positive cells for IFN gama, compared to OVA (p>0.05). Elastic fiber content were reduced only in OVAMW, OVADW and OVAW groups compared to OVA animals (p<0.05). The association of 1400W and montelukast treatments potentiated the reduction of actin, elastic fibres and isoprostane PGF2 alpha contents and the number of IL4, IL5, TIMP1, IFN gama, TGF beta and iNOS positive cells compared to montelukast group (p<0.05). The treatments with 1400W and dexamethasone contributed to a greater reduction of elastic fibers, actin and isoprostane PGF2 alpha contents and the number of IL4, IL5, IFNgama and TIMP1 positive cells compared to dexamethasone group (p<0.05). Conclusions: Corticosteroid treatment associated to iNOS inhibition contributes to a greater reduction of extracellular matrix remodeling, decreases the oxidative stress, and also is efficient to attenuate the Th2 inflammatory response in distal lung parenchyma. On the other hand, montelukast treatment associated to iNOS inhibition showed a higher efficacy to reduce elastic fibres content, oxidative stress activation, actin content and IL4 and IL5 expression in distal lung parenchyma. These associations may represent future pharmacological tools for controlling distal pulmonary histopathological alterations induced by chronic inflammation

Full textThe aerobic training (AT) promotes benefits for asthmatics, but the anti-inflammatory mechanisms are not known. Experimental studies of asthma have shown that AT reduces the pulmonary allergic chronic inflammation (PACI) and response Th2, however no study has ever explained when the protective effects are initiated and which is the main anti-inflammatory pathway triggered. Aim: To evaluate the effect of AT over time in a murine model of asthma to identify when the anti-inflammatory effects is started and reverse bronchial remodeling (BR). Methods: BALB/c (160 mice) were divided into 4 groups: Control (CT): not induced to PACI and untrained; Aerobic Training (TA): not induced to PACI and trained; OVA: induced to PACI and untrained; OVA + TA: induced to PACI and trained. After that were created others subgroups 1, 3, 7, 15 and 30 days AT, that is, each group was repeated 5 times to investigate the effect of AT over time. The OVA groups were sensitized with i.p. OVA (OVA+AlumHidrox), and then the mice were induced after the PACI with aerosol of OVA (1-3%) started on the 21st day (3 x week, 30 min./Session). Adaptation to TA was held between 21-23, on the 25th day the physical test was performed, and on day 28 AT was begun (50% intensity, frequency x 5 for 4 weeks). Twenty four hours of the after last session of AT (1, 3, 7, 15 and 30 days) the mice were anesthetized, euthanized and the bronchoalveolar lavage fluid was collected (BALF) (Total and differential cell count) and blood was used to quantify immunoglobulins (IgE and IgG1) by passive cutaneous anaphylaxis reaction (PCA) technique, the pulmonary tissue was removed and used to evaluate the mediators IL-4, IL-5, eotaxin, RANTES, ICAM-1, VCAM-1, TGF-b, VEGF, osteopontin (OPN), NF-kB, FOXP3, glucocorticoid receptor (GR), and antiinflammatory IL-10 and IL-1ra (immunohistochemistry and quantified by morphometry), was also the quadriceps muscle to assess the expression of myokines (IL-10, IL-1ra and IL-6) (by immunohistochemistry and image analyses). The BR (smooth muscle, epithelium, collagen and elastic fibers deposition, and mucus production) was also evaluated by image analysis. Results: It was not observed any production of myokines (p>0.05). The levels of IgE and IgG1, cell migration, production of inflammatory mediators, and the BR were increased in the OVA groups (p<0.05); that still showed a decreased production of the GR (p<0.05). The AT promoted an increase of GR in the airway smooth muscle from the 3rd day, the production of IL-10 and IL- 1ra were increased from day 7 for cells peribronchial, while NF-kB, IL-4, IL-5, eotaxin, RANTES, ICAM-1, VCAM-1, VEGF, eosinophil counting in BALF were reduced, and reversed the smooth muscle thickening, epithelium and deposition of collagen fibers too (p<0.05). Interestingly, the decreasing of TGF-b occurred in the 3rd day, and OPN, elastic fibers, mucus occurred after 15 days of AT, while IgE and IgG1, and neutrophils were reduced only after 30 days (p<0.05). Conclusion: The anti-inflammatory mechanism by increasing the GR on the smooth muscle of the airways was initiated from the 3rd day of the AT, followed by an increase of IL-10 and IL-1ra and a reduction of NF-kB from the 7th day of the AT, reversed the effects of chronic allergic inflammation and bronchial remodeling

Full textAllergic rhinitis (AR) is the most common disease mediated by IgE, affecting approximately 500 million people worldwide. The AR is the clinical expression of the link between the IgE-antibodies and antigens in the nasal mucosa resulting in inflammation. Such antibodies were detected in nasal secretions of allergic rhinitis patients. As treatment for this morbidity there is specific immunotherapy (IT) as only immunomodulatory specific antigen approach. It was demonstrated that IT generates a decrease in the late response to the allergen both in the skin and in the mucosa of the respiratory tract and this reduction correlates with the decrease in the number of infiltrating cells and in the amount of inflammatory mediators. Objective: To determine the local response of specific IgE and IgG4 in nasal lavage fluids of patients with allergic rhinitis before and after treatment with specific allergen immunotherapy to house dust mite for a period of 6 months; determine the standard inflammatory response of Th1 / Th2 / Th17 and evaluate symptom score and cell counts in nasal lavage. Method: We selected patients sensitized to Dermatophagoides pteronissinus diagnosed with persistent allergic rhinitis. Nasal symptoms were assessed by Nasal Index Score, and before treatment, allergen nasal challenge and collection of nasal lavage fluid were performed. After 6 months of treatment or placebo, the patients were reevaluated. IgE specific for Der p 1 and 2, total IgE and IgG4 specific for Der p 1, total cell count were determined as well as Th1 / Th2 and Th17 cytokines. Results: We analyzed 19 patients in the immunotherapy group and 17 in the placebo group. The evaluation of symptoms by NIS scale after 6 months of intervention showed significant differences in favor of the immunotherapy group. The concentration of the extract used in the nasal challenge was higher in the immunotherapy group after 6 months of treatment but without statistical significance. The total IgE decreased after the intervention as well as the total cell count in nasal lavage. The dosage of the free cytokines in nasal lavage fluid did not change significantly. In the nasal provocation we observe an increasing in IL-13 and IL-10 in both treatment groups. Conclusion: We observed no local changes in specific IgG4 or specific IgE response in nasal lavage fluid of patients with allergic rhinitis before and after treatment with specific allergen immunotherapy to house dust mite for a period of 6 months. There was an improvement in symptom scores and a decreased of total IgE and cell counts in nasal lavage

Full textReacções Alimentares Adversas (RAA) são definidas como reacções associadas à ingestão de um alimento ou aditivo alimentar. As RAA podem ter uma base imunológica ou não imunológicas e têm carácter não sazonal. O objectivo deste estudo consistiu em caracterizar a abordagem europeia dos especialistas em dermatologia, no que respeita a RAA no cão. Neste sentido recorreu-se ao método de diagnóstico mais utilizado e a sua duração, à percentagem de pacientes que responde à dieta de eliminação, à percentagem de casos em que se chega a um diagnóstico definitivo e as suas principais falhas, e qual o maneio a longo prazo mais utilizado. Este estudo teve ainda como objectivo caracterizar os pacientes de acordo com as suas características individuais, tais como sexo, raça, idade e sinais clínicos. O presente trabalho baseou-se na elaboração de um inquérito sobre “Reacções Alimentares Adversas em cães”, de forma a analisar as respostas dos Médicos Veterinários europeus, dos quais se obteve 65 respostas. As principais raças afectadas são o Labrador Retriever, o West Highland White Terrier e o Pastor Alemão, não existindo predisposição sexual. Ao contrário do esperado, os primeiros sinais clínicos aparecem entre o primeiro e o terceiro ano de idade, sendo eles a piodermatite superficial, a sintomatologia gastrointestinal e a dermatite por Malassezia. Para diagnosticar a RAA, deverá ser feita uma dieta de eliminação durante 8 semanas, à base de proteínas hidrolisadas, embora estudos defendam a utilização de uma dieta caseira. Posteriormente deverá ser realizada a dieta de provocação, sendo a dieta original a escolha mais adequada. No entanto, apenas uma baixa percentagem chega ao diagnóstico definitivo, sendo esta explicada pelo incumprimento das dietas, por parte dos proprietários. Uma vez confirmado o diagnóstico, cinquenta por cento dos médicos veterinários inquiridos recomenda fazer a dieta de eliminação como dieta de manutenção a longo prazo, sendo que os restantes clínicos referem que a escolha irá depender do paciente e do proprietário. Este estudo mostrou-se inovador e proveitoso, uma vez que estudos semelhantes são ainda inexistentes na literatura veterinária.
Adverse Food Reactions (AFR) are defined as reactions associated with the ingestion of food or food supplement. The AFR can be of immunologic or non-immunologic nature and have no seasonal character. The aim of the research reported in this study was to document the dermatology experts’ European approach concerning the impact of AFR in dogs. As such the investigation focused upon the most common used diagnosis method and its duration, the percentage of patients that respond to the elimination diet, the percentage of cases where a concluding diagnosis is found and main faults are identified, and the most widely used long-term management. The aim of this research was also to characterize the patients according to their individual features, such as gender, breed, age and clinical signs. The investigation focused upon the elaboration and application of a enquire on “Adverse Food Reactions in dogs” to european Veterinarians. Reported here are the findings from a sample of 65 european Veterinarians. The main breeds affected are the Labrador Retriever, the West Highland White Terrier and the German Shepherd, with absence of sexual predisposition. Unexpected findings where revealed, the first clinical signs appear between the first and the third year of age. Those are superficial pyoderma, gastrointestinal symptoms and Malassezia dermatitis. In order to diagnose AFR, dogs should be submitted to an elimination diet based on hydrolysed proteins for 8 weeks, although some studies suggest the use of a homemade diet. Subsequently the dog should be submitted to a provocation diet, being the original diet the most adequate. However, only a small percentage achieves a concluding diagnosis. This fact is explained by the owners’ inability to comply with the established diet. The results suggest that once the diagnose is confirmed, fifty per cent of the inquired veterinarians recommend the elimination diet as a long-term maintenance diet, while the other fifty per cent suggest that the choice will depend on the patient and its owner. The findings and insights gathered in this study suggest its relevance, proving to be innovative and useful, since there are no other similar studies in the veterinary literature.

Full textO grande número de casos de Reações Alimentares Adversas em cães, nos últimos anos, é um problema crescente e tem determinado a necessidade de mais estudos, para se conseguir obter um diagnóstico exato e um tratamento eficiente. As RAA estão associadas à ingestão de um alimento ou aditivo alimentar. Apesar de ser um tipo de distúrbio bastante comum, a sua apresentação clínica varia muito, dependendo da sua gravidade, o que dificulta não só o diagnóstico, mas também o tratamento. A anamnese detalhada com registo exato da dieta e dos sintomas é o principal indicador para suspeita de RAA. Pretendeu-se com esta tese caracterizar a perspetiva dos Médicos Veterinários portugueses, analisar as suas respostas no que concerne à etiologia, patogenia, sintomas, diagnóstico, tratamento, alimentos alergizantes e tipos de dietas para chegar a conclusões acerca do tema. Este estudo teve também como objetivo saber qual o método de diagnóstico mais utilizado em Portugal, que percentagem de pacientes responde à dieta de eliminação, qual o número de casos com diagnóstico definitivo, que maneio é escolhido a longo prazo e caracterizar os pacientes de acordo com as suas características (género, raça, idade) e sinais clínicos. De modo a obter um resultado sólido, para suportar esta tese, procedeu-se a um questionário que foi enviado a 623 Médicos Veterinários espalhados por todos os 18 distritos de Portugal Continental. Desses 623 enviados responderam 189. Este estudo permite a atualização dos dados nacionais e obtenção de referências atualizadas em relação ao tipo de diagnósticos diferenciais, diagnósticos e tratamento.
The large number of cases related to Adverse Feeding Reactions in dogs is an growing problem and to mitigate the problem it is required the need for further studies in order to obtain an accurate diagnosis that will result in a more efficient treatment. RAA is associated with the ingestion of a certain food or food additives. Although it is a fairly common type of disorder, its clinical presentation varies greatly depending on the severity, which makes it difficult not only to diagnose but also for the treatment itself. Detailed anamnesis with an accurate diet and symptom registration is the main indicator to suspected RAA. The objective of this thesis was to characterize the perspective of the Portuguese Veterinary Doctors, to analyze their responses regarding etiology, pathogenesis, symptoms, diagnosis, treatment, allergenic foods, types of diets, type of aliment in order to reach conclusions about the topic. In addition, this study had also another objectives such as, understand which method is most used to diagnose RAA in Portugal, which percentage of patients responds well to the elimination diet, the amount of cases with definitive diagnosis, what management is chosen in the long term and characterize patients according to characteristics (gender, race, age) and clinical signs. In order to obtain a solid result to support my thesis, a questionnaire was sent to 623 veterinarians spread throughout all 18 districts of Continental Portugal. Of those 623, 189 responded. This study allows an update of available national data and references regarding the type of differential diagnoses, diagnoses and treatment.

Full textO cuidado acrescido por um bom estado de saúde, por parte da população mundial, tem vindo a aumentar. Para isso, os consumidores devem encontrar-se informados face aos géneros alimentícios que compõem a sua dieta alimentar. O consumidor tem como direito ser esclarecido em relação aos géneros alimentícios que adquire. Atualmente, na União Europeia, existem doze indicações a considerar num rótulo, nomeadamente a denominação de venda, a quantidade líquida, entre outras. Relevante é a lista de ingredientes: a composição do produto é determinante para uma escolha informada por parte do consumidor, sobretudo a inclusão de substâncias que provocam alergias. Para todos os produtos não pré-embalados disponíveis para comercialização nas secções de Padaria/Pastelaria, Charcutaria e Livre Serviço (Queijos) é necessário transpor a informação para as etiquetas colocadas no ponto de venda diariamente, tendo sido definido como o objetivo principal da presente tese. Destacam-se os potenciais alergénios e incluem-se indicações legalmente obrigatórias, como as condições de conservação. Para se proceder à realização deste objetivo é imprescindível a consulta do Regulamento (UE) nº 1169/2011 do Parlamento Europeu e do Conselho de 25 de Outubro de 2011 relativo à prestação de informação aos consumidores sobre os géneros alimentícios. A passagem da informação entre fornecedor e cliente torna-se essencial, mas fundamental é também a informação interna na empresa, entre todos os colaboradores. As restantes tarefas a realizar durante o período de estágio incidiram na revisão e atualização da documentação no âmbito do sistema HACCP implementado (Fichas Técnicas de produtos elaborados na secção Talho; Rotulagem de produtos de marca própria da empresa; Procedimentos Internos de Boas Práticas de Higiene e de Funções; Questionários online de avaliação de Fornecedores e de satisfação de Clientes). Foram ainda atualizadas as Instruções Gerais de Segurança no âmbito do Sistema de Segurança e Higiene no Trabalho, com referências explicitas ao cumprimento das Normas de Segurança Internas.
An increasing demand for good health by the world’s population has been increasing significantly. Therefore, with that being said, the customers should be conscious of what the foodstuffs that constitute their diets are made of. The consumer has the right to be enlightened regarding the acquired food. In nowadays, inside the European Union, there are twelve signs to consider on a label, including the product name, net value, among others. The list of ingredients is imperative: the product composition is critical for a conscious choice made by consumers, particularly the addition of substances that might cause allergies. For all non pre-packed products commercialized in their respective sections of Bakery/Confectionery, Charcuterie and Free Service (Cheeses) it is essential to transpose the information for the labels placed on points of daily sales, something that was established as the focal point of this dissertation. Moreover, should be given special emphasis to the potential allergens and include legally binding statements such as storage conditions. To proceed with the accomplishment of this goal, it is vital to check the Regulation (EU) nº 1169/2011 of the European Parliament and the Council 25 of October of 2011 concerning the information given to the consumers on foodstuff. The information sharing between supplier and consumer is very important as well as the internal communication among all employees inside the same company. The remain tasks to be undertaken, during the stage period, were focused on the revision and updating of the documentation under the implemented HACCP system (Data Sheets of products produced in the butchery section; Labeling of private label products of the company; Good Hygiene Practices and Internal Procedures and Functions, online survey about the Supplier and Customer satisfaction). The general safety instructions under the health safety and safety at work system were also updated, with explicit references to the fulfillment of the Internal Security Standards.
