Abstract:
Introduction: During physical exercise, the level of haematological parameters changes depending on the intensity and duration of exercise and the individual's physical fitness. Research results, based on samples taken before and after exercise, suggest that haematological parameters increase during incremental exercise. The purpose of the research work was to evaluate the acute effect of continuous running on Red Blood Cell (RBC), Red blood cell distribution width (RDW) and Packed Cell Volume (PCV)of physically trained boys has been aimed. Methods: Ten (10) physical education male students with an average age of 23.16±1.85 years participated in this study on voluntary basis. Red blood cell (RBC), Red blood cell distribution width (RDW) and Packed Cell volume (PCV) of the students were analyzed before running (BR) and just after 35 minutes of continuous running (AR). To find out the effect of contentious running ‘t’ test was calculated for each variable. In order to determine all those hematological parameters, blood samples with 5 ml EDTA were taken from the forearm antecubical area before and after contentious running, and analyzed in laboratory with using auto-analyzer (Sysmex XP- 100). Result: Measurement results were presented as average and standard deviation. Student T-test for dependent samples was used in order to make a comparison between BE and AE values. P<-0.01 value was considered to be significant. The result of the study revealed that, the increase in AR than BR values for Red Blood Cell (RBC) and packed cell volume (PCV) significantly but no significant changes shown in case of Red Blood Cell distribution width (RDW). Conclusion: Conclusively Red blood cell (RBC) and Packed Cell Volume (PCV) displayed significant incensement and insignificant decrease of RBC distribution width (RDW) in relation to acute effect of continuous running.

Abstract:
Abstract Red blood cell distribution width (RDW) measures erythrocyte size variability and strongly predicts cardiovascular disease (CVD) morbidity and mortality. Our prior cross-sectional analysis showed that inflammation, metabolic rate, and body habitus are independently associated with RDW. To better understand determinants of RDW, we performed a longitudinal analysis associating changes in RDW within the normal range (11.5 - 15.0%) with age, sex, race, and changes in other erythrocyte properties, major CVD risk factors, and other physiologic measures. Data were from 452 men and 482 women, aged 50 to 94 years enrolled in the Baltimore Longitudinal Study of Aging. For each participant and each predictor, change was the regression coefficient of time from a linear model. Coefficients of candidate correlates were then used to predict change in RDW in multiple linear regression models that were reduced by backward selection. In the final model, increasing erythrocyte number (STβ=1.4980, P< 0.001), mean platelet volume (STβ=0.2019, P< 0.001), anion gap (STβ=0.1754, P< 0.001), blood urea nitrogen (STβ=0.0684, P=0.0395), urine albumin-creatinine ratio (STβ=0.1007, P=0.0015), alanine transaminase (STβ=0.1580, P< 0.001), interleukin-6 (STβ=0.2338, P< 0.001), and diastolic blood pressure (STβ=0.0769, P=0.0107) and decreasing glucose (STβ=-0.2425, P< 0.001), vitamin B12 (STβ=-0.1310, P< 0.001), and C-reactive protein (STβ=-0.1801, P< 0.001) were associated with increasing RDW. The association of age with increasing RDW was independently explained by decreasing glucose (STβ=-0.2310, P< 0.001). Taken together, these findings suggest that rising RDW may reflect accelerated aging. Studies in larger, more diverse populations are necessary to confirm these findings and determine their role in mechanisms leading to age-associated increases in RDW.

Abstract:
Background Red cell distribution width (RDW) is a hematological parameter routinely obtained as part of the complete blood count. Recently, RDW has emerged as a potential independent predictor of clinical outcomes in adults with sepsis. However, RDW as a mortality predictor in pediatric populations has not been well established.Objective To determine the relationship between RDW value and mortality outcomes in pediatric sepsis patients.Methods We performed a cross-sectional study of 40 consecutive pediatric patients with sepsis admitted to the PICU from December 2013 to March 2014. All patients’ RDW were collected within 24 hours of sepsis diagnosis. We determined the association between RDW and hemoglobin (Hb) using Spearman’s correlation. The RDW values of 11.5-14.5% were considered to be normal while those > 14.5% were considered to be elevated. We compared mortality and PICU length of stay (LoS) between the normal and elevated RDW groups using Chi-square and Mann-Whitney tests.Results The median age of patients was 34 months (range 2 months to 17 years). There were 28 (70%) male subjects. Subjects’ median RDW was 14.8% (range 11.2-27.8%) and was not correlated with Hb (r=0.056; P=0.73). Mortality rates in the normal and elevated RDW groups were 40% and 45%, respectively. There were no significant associations between RDW group and mortality (P=0.749) or PICU LoS (P=0.350).Conclusion Unlike in adults, RDW values are not correlated with mortality in pediatric sepsis patients.

Abstract:
Abstract Red blood cell distribution width (RDW) describes the amount of variation in blood cell volume and size and increases with age. Higher RDW predicts all-cause mortality, metabolic syndrome, diabetes, and markers of glycemic control, such as glycosylated hemoglobin. However, mechanisms that connect high RDW with these health outcomes are unknown. Thus, identification of high risk in these patients cannot be addressed. This study aims to identify metabolites and pathways that are associated with high levels of RDW in community-dwelling older adults. Using data from the Baltimore Longitudinal Study of Aging, we identified 1,004 cognitively normal participants (mean age: 67.1±13, 48% women, 26% black) with concurrent data on RDW and comprehensive targeted plasma metabolites by Biocrates p500. Participants were grouped into RDW quartiles (Q1:14%). Associations of metabolites with quartiles of RDW were examined using multivariable linear regression with Q1 being the reference group. Models were adjusted for age, sex, and race. Compared to Q1, Q4 had higher concentrations of SM(OH)C14:1, PC ae C30:2, and hypoxanthine, and lower concentrations of DHEAS, Cortisol, Tryptophan, and Hex2Cer(d/18:1/24:0) (all p<0.01). These metabolites are critical components of sphingolipid metabolism and steroid hormone biosynthesis pathways. Elevated RDW was associated with metabolites derived from classes of hormones, amino acids, ceramides, sphingomyelins, PCs, and nucleobases. Individuals with elevated RDW (i.e. ≥14%) may have disrupted sphingolipid metabolism and steroid hormone biosynthesis. These pathways can be targeted for prevention.

Abstract:
Abstract Red cell distribution width (RDW) is a measure of erythrocyte size variability. Recent studies have shown that RDW is a predictive, and prognostic marker of mortality and cardiovascular (CVD) events in the general population and in CVD patients. This study aimed to investigate the association between RDW and CVD risk in a large sample of adults. A subsample of CVD free participants of the ELSA-Brasil cohort were included (n=4,481). In the cross-sectional approach, multiple regression analysis was used to investigate the association between RDW and the Framingham Risk Score (FRS). Linear mixed effect model evaluated whether baseline RDW predicted changes in CVD risk after about four-year follow up. Cross-sectional analysis showed that RDW was independently associated with FRS, participants in the fourth-quartile of RDW distribution had a 29% higher FRS than those in the first-quartile RDW (p<0.001). A longitudinal analysis revealed that RDW remained associated with increased FRS. In this large cohort of adult Brazilians, RDW was independently associated with increased CVD risk, as measured by the FRS, both at baseline and after four-year follow-up. However, RDW did not predict change in CVD risk in this short-term follow up.

Abstract:
Atrial fibrillation (AF) is the most frequent arrhythmia encountered in clinical practice and is a major health problem associated with remarkable morbidity, mortality and has considerable healthcare costs. Red blood cell distribution width (RDW) reflects the heterogeneity of the volume and size of red blood cells. It is an easily measured and inexpensive index that has been associated with several cardiovascular disease states. Accumulating evidence suggests that RDW is a prognostic marker of AF in various clinical settings. In this article, we review the available data regarding the prognostic role of RDW in AF development and perpetuation in diverse disease states as well as its role on the prediction of adverse outcomes.

Abstract:
Background: The red blood cell distribution width (RDW) is a simple measure of red blood cell size heterogeneity. A high degree of anisocytosis, expressed by RDW >15%, is observed in certain anemias, but also in other disorders, where RDW >15% is associated with worse prognosis. We questioned whether the RDW/hemoglobin ratio (RDW/Hb) might closer relate to disease severity than RDW. Design: Cross sectional study Patients: 76 residents of two Department of Comprehensive Nursing Care. Method: Physicians classified the patients according to their clinical status in three groups: "stable", “severe-unstable”, and "intermediate". An outside observer extracted from the patients' files the results of RDW (elevated if >15%), hemoglobin, iron, and transferrin. The RDW (%)/Hb (g/dL) ratio and tansferrin saturation (TSAT) were computed. The associations between RDW, RDW/Hb, TSAT, and the patients' clinical status were assessed. Results: In residents of Department A, RDW >15% was found in 33% of 19 stable patients, in 58% of 10 patients with intermediate severity, and in 81% of 10 patients classified severe-unstable. The RDW/Hb ratio >1.4 was found in 24% of stable patients, in 73% with intermediate severity, and in 93% of the severe-unstable patients. In Department B, 36 out of 38 patient's were classified stable: in 61.2 % the RDW was >15% and in 38% the RDW/Hb was >1.4. Conclusions: In a heterogenic population presenting multimorbidity, the RDW and to a higher degree the RDW/Hb (p <0.00001), correlated with the patients' disease severity.

Abstract:
Introdução: A pré-eclâmpsia é uma das principais causas de mortalidade materna e perinatal em todo o mundo. A relação entre a amplitude de distribuição das hemácias (Red Cell Distribution Width - RDW) e hipertensão arterial já está bem documentada, porém há uma escassez de dados relacionando RDW com pré-eclâmpsia. Material e métodos: Estudo observacional analítico retrospectivo, realizado no período de 2014 e 2015, composto por 108 participantes no grupo de estudo (50 pré-eclâmpsia leve e 58 pré-eclâmpsia grave) e 101 participantes no grupo controle. A hemoglobina, RDW, plaquetas e outros índices hematológicos foram medidos como parte do hemograma automatizado. Resultados: Não houve diferença no RDW entre as gestantes do grupo controle e grupo com pré-eclâmpsia leve (14,68 ± 1,64 vs. 14,22 ± 1,87; p=0,385), grupo controle e grupo com pré-eclâmpsia grave (14,68 ± 1,64 vs. 14,24 ± 1,78; p=0,386) e grupo controle e grupo com pré-eclâmpsia (14,68 ± 1,64 vs. 14,23 ± 1,81; p=0,063). Conclusão: Os níveis de RDW sérico materno não estão associados com a presença da pré-eclâmpsia e os graus de gravidade da doença.<br>Introduction: Preeclampsia is one of the main causes of the maternal and perinatal mortality all over the world.

Abstract:
Conselho Nacional de Desenvolvimento Científico e Tecnológico<br>Ischemic heart diseases stands out among the diseases that affect the cardiovascular system due to its high prevalence and its impact on mortality in the general population. Ischemic heart disease is the leading worldwide cause of mortality. Fenomenum that also happens in the Americas and Brazil. The term acute coronary syndrome (ACS) is used to describe a heterogeneous spectrum of clinical conditions associated with acute myocardial ischemia, including unstable angina and acute myocardial infarction (AMI). The plurality in its clinical presentation represents a diagnostic challenge for clinicians. Moreover, appropriate risk stratification is mandadatory in all patients with ACS. Some clinical tools such as physical examination, electrocardiographic observations and risk scores are extremely usefull to identify patients at high risk of unfavorable clinical outcomes. Scores of risk stratification, among those the Global Registry of Acute Coronary Events (GRACE), are widely used in the prognostic evaluation of patients with ACS.Some plasma biomarkers have also been used to improove risk stratification. The GRACE score is a fundamental part of the assessment of patients with ACS and may even prevent or minimize adverse consequences in these individuals. Nevertheless, the search for new potential prognostic parameters that could add information to these establised scores has been the subject of intense research. In this context, stands out the use of routine hematological tests , since the complete blood count is readily available for clinical use and has a good cost-benefit relationship. Recent studies have investigated the potential role of some of red cell indices, especially anemia and red cell distribution width (RDW), in the prognostic evaluation of patients with several cardiovascular conditions. The presence of anemia and elevated RDW in patients with ACS have been independently associated with increased risk of adverse events such as heart failure, recurrent ischemic events, and death. We have hipotezazed that the addition of the hemalological indices to the GRACE score would improve its ability to stratify patients.The main objective of this study was to investigate whether inclusion of anemia or RDW, assessed at admission, in the GRACE score model to predic in-hospital mortality, could improve the discrimination and calibration of these model, as well as risk stratification in patients with ACS. For this, a cohort study, including 109 patients with AMI was carried out. Cox regression models including the variables of the GRACE score and RDW or anemia were constructed. Measures of calibration and discrimination, and reclassification of patients were also calculated for the new models. The new models, either with the inclusion of anemia, or the addition of RDW showed adequate calibration and discrimination. Furthermore, the addition of these parameters to the original model allowed adequate reclassification of patients in different categories of risk. The red cell indices, anemia and RDW showed potential prognostic for use in risk assessment of patients with ACS, allowing the improvement of risk stratification performed through the GRACE score.<br>A cardiopatia isquêmica destaca-se entre as doenças que acometem o sistema cardiovascular, devido à sua alta prevalência e a seu impacto sobre a mortalidade na população em geral. As doenças isquêmicas do coração são a principal causa de mortalidade mundial, nas Américas e no Brasil. O termo SCA é usado para descrever um espectro heterogêneo de condições clínicas associadas com isquemia aguda do miocárdio, incluindo angina instável e infarto agudo do miocárdio (IAM). A diversidade na apresentação clínica de pacientes com esta patologia representa um desafio para os clínicos em termos de diagnóstico e de estratificação de risco apropriada. Algumas ferramentas clínicas como exame físico, observações eletrocardiográficas e escores de risco, são de extrema relevância na identificação de pacientes com alto risco de desfechos clínicos desfavoráveis. Além disso, alguns biomarcadores plasmáticos também vêm sendo utilizados com este propósito e a busca por novos parâmetros com potencial prognóstico tem sido alvo de intensas pesquisas. Neste contexto, destaca-se a utilização dos testes hematológicos de rotina na estratificação de risco, uma vez que o hemograma é um exame amplamente disponível para uso clínico e possui uma boa relação custo benefício. Estudos recentes tem investigado o potencial papel de alguns dos índices hematimétricos, especialmente anemia e amplitude de distribuição dos eritrócitos (RDW), na avaliação prognóstica de pacientes apresentando diversas condições cardiovasculares. A presença de anemia, bem como valores elevados de RDW em pacientes com SCA tem sido independentemente associados com maior risco de eventos adversos como mortalidade, desenvolvimento de insuficiência cardíaca e ocorrência de eventos isquêmicos recorrentes. Os escores de estratificação de risco, principalmente o Global Registry of Acute Coronary Events (GRACE), são amplamente utilizados na avaliação prognóstica de pacientes com SCA. No entanto, os modelos disponíveis atualmente não incluem os índices hematimétricos na determinação do risco do paciente. Considerando que a estratificação de risco é parte fundamental da avaliação de pacientes com SCA, podendo evitar ou mesmo minimizar consequências adversas nestes indivíduos, o principal objetivo deste estudo foi investigar se a inclusão de anemia ou RDW, avaliados na admissão hospitalar, ao escore GRACE para a predição de mortalidade durante o período de internação hospitalar, podem melhorar a calibração e discriminação do modelo, bem como a estratificação de risco em pacientes com SCA. Para isso, um estudo de coorte, incluindo 109 pacientes com IAM, foi realizado. Modelos de regressão de Cox incluindo as variáveis do escore GRACE e o RDW ou a anemia foram construídos. Medidas de calibração e discriminação também foram calculadas, bem como o percentual de reclassificação dos pacientes para os novos modelos propostos. Os novos modelos, tanto com a inclusão de anemia, quanto com a adição de RDW, apresentaram adequada calibração e discriminação. Além disso, a adição destes parâmetros ao modelo original permitiu uma adequada reclassificação dos pacientes em diferentes categorias de risco. Os índices hematimétricos, anemia e RDW, demonstraram potencial prognóstico para utilização na avaliação de risco de pacientes com SCA, permitindo o aprimoramento da estratificação de risco realizada através do escore GRACE.

Abstract:
Introdução: Os parâmetros hematológicos, nomeadamente o coeficiente de variação da amplitude de distribuição dos glóbulos rubros e o desvio padrão da amplitude de distribuição dos glóbulos rubros, têm demonstrado em vários estudos uma forte correlação com eventos cardiovasculares adversos major e morte após cirurgia. Este estudo tem como objetivo investigar a associação entre os parâmetros hematológicos no pré-operatório e a ocorrência de eventos adversos no pós-operatório, incluindo enfarte do miocárdio e mortalidade. Métodos: Todos os doentes adultos submetidos a cirurgia vascular arterial eletiva desde Janeiro até Abril de 2015 num hospital universitário foram incluídos neste estudo coorte observacional prospetivo. O outcome primário foi morte após 30 dias desde o dia da cirurgia. O outcome secundário foi enfarte do miocárdio após 30 dias desde o dia da cirurgia. Resultados: Na análise univariada de mortalidade, a prevalência de fibrilação auricular, doença renal crónica e estado funcional dependente foi superior em doentes falecidos. Após a análise multivariada, a idade (OR ajustado de 1.08, 95%CI 1.01-1.15, p=0.027) e o desvio padrão da amplitude de distribuição dos glóbulos rubros (OR ajustado 1.08, 95%CI 1.01-1.16, p=0.032) subsistiram como fatores independentes de mortalidade.

Abstract:
Introdução: Os parâmetros hematológicos, nomeadamente o coeficiente de variação da amplitude de distribuição dos glóbulos rubros e o desvio padrão da amplitude de distribuição dos glóbulos rubros, têm demonstrado em vários estudos uma forte correlação com eventos cardiovasculares adversos major e morte após cirurgia. Este estudo tem como objetivo investigar a associação entre os parâmetros hematológicos no pré-operatório e a ocorrência de eventos adversos no pós-operatório, incluindo enfarte do miocárdio e mortalidade. Métodos: Todos os doentes adultos submetidos a cirurgia vascular arterial eletiva desde Janeiro até Abril de 2015 num hospital universitário foram incluídos neste estudo coorte observacional prospetivo. O outcome primário foi morte após 30 dias desde o dia da cirurgia. O outcome secundário foi enfarte do miocárdio após 30 dias desde o dia da cirurgia. Resultados: Na análise univariada de mortalidade, a prevalência de fibrilação auricular, doença renal crónica e estado funcional dependente foi superior em doentes falecidos. Após a análise multivariada, a idade (OR ajustado de 1.08, 95%CI 1.01-1.15, p=0.027) e o desvio padrão da amplitude de distribuição dos glóbulos rubros (OR ajustado 1.08, 95%CI 1.01-1.16, p=0.032) subsistiram como fatores independentes de mortalidade. Na análise univariada de enfarte do miocárdio, a prevalência de diabetes, doença renal crónica, estado funcional dependente, estado físico ASA IV e medicação com insulina foi mais elevada em doentes com episódio de enfarte no pós-operatório. Na análise multivariada de enfarte do miocárdio, o estado funcional dependente (OR ajustado de 4.8, 95%CI 1.6-15.0, p=0.007), a medicação com insulina (OR ajustado de 4.4, 95%CI 1.5-12.6, p=0.007), e o desvio padrão da amplitude de distribuição dos glóbulos rubros (OR ajustado de 1.1, 95%CI 1.02-1.19, p=0.020) foram preditores independentes.

Abstract:
博士<br>國立中興大學<br>轉譯醫學博士學位學程<br>106<br>Although red cell distribution width (RDW) has emerged as a biomarker of clinical prognostic value across a variety of clinical settings in the last two decades, limited evidence is available for its role in pre-dialysis chronic kidney disease (CKD) as well as in end-stage renal disease patients undergoing continuous ambulatory peritoneal dialysis (CAPD). We conducted two retrospective observational cohort studies，one of 1075 stage 3-5 CKD patients and the other of 313 CAPD patients in a medical center in central Taiwan. The patients’baseline information for adjustments included demographic data, laboratory values, medications, and comorbid conditions. The outcome of interests in our studies was patient mortality. Multivariate Cox regression analysis was used to test the independent role of RDW in predicting mortality. The results showed that in CAPD patients the adjusted hazard ratios for the high RDW group versus the low RDW group were 2.58 (95% confidence interval (CI)=1.31-5.09，p=0.006) and 3.48 (95% CI=1.44-8.34, p=0.006) for all-cause and cardiovascular disease (CVD)-related mortality, respectively. And in pre-dialysis CKD patients the high RDW group was correlated with hazard ratios of 2.19 (95% CI=1.53-3.09, p＜0.001), and 2.28 (95% CI=1.14–4.25, p=0.019) for overall mortality and CVD-related mortality, respectively, as compared with the low RDW group. Given that RDW is a readily available hematological parameter without the need for additional cost, we suggest that it can be used as a valuable index to stratify the risk of mortality in CKD patients beyond a diagnosis of anemia.

Abstract:
Red blood cell (RBC) indices not only assess anemia but also play a crucial role in predicting and evaluating significant health issues, such as cardiovascular morbidity and mortality from cancer, cardiovascular disease, and infection. Ongoing research is expected to further elucidate these associations. Factors associated with RBC indices and red blood cell distribution width (RDW) beyond the normal range include nutritional imbalances, underlying chronic disease conditions, oxidative stress, chronic inflammation, and insulin resistance. Compared to studies related to outcomes, research on factors that lead to changes in RBC indices is limited, indicating the need for further investigation. Some RBC parameters, such as hemoglobin/RDW and mean corpuscular volume, are highlighted as promising, cost-effective, and readily accessible prognostic and diagnostic tools for cardiovasulcar disease, cancer, and all-cause mortality. Their versatility, along with insights into the underlying physiological changes, suggests they warrant further exploration and validation through prospective studies. This could represent a significant advancement in prognosis and patient management for some diseases.

Abstract:
A amplitude de distribuição eritrocitária (RDW, do inglês Red Blood Cell Distribution Width), é um parâmetro simples e barato, obtido a partir do hemograma, que representa as variações de tamanho e heterogeneidade dos eritrócitos. No entanto, os valores do RDW podem apresentar variações na técnica analítica utilizada, assim como pelos algoritmos utilizados na obtenção do resultado, nos equipamentos hematológicos. O objetivo principal do estudo foi avaliar as possíveis variações nos resultados do RDW, assim como outros parâmetros do hemograma associados, obtidos dos analisadores hematológicos Sysmex XN 350® e Hemacounter 60-RT 7600®. Foram analisadas amostras biológicas de sangue venoso da rotina diária do Laboratório Universitário de Análises Clínicas (LUAC), da Universidade Estadual de Ponta Grossa, Paraná. As amostras biológicas foram processadas no analisador hematológico XN 350® e em seguida, no contador hematológico Hemacounter 60-RT 7600®. Os parâmetros hematológicos analisados foram: contagem de eritrócitos, hematócrito (HCT), Volume Corpuscular Médio (VCM) e RDW. Foram analisados e avaliados 89 hemogramas nos dois equipamentos, bem como a concordância entre os analisadores hematológicos. Para o parâmetro hematológico RDW, assim como para os parâmetros associados, houve concordância entre os dois equipamentos, não apresentando alteração no ponto de vista clínico. Esses resultados demonstram a importância de cada laboratório clínico analisar a compatibilidade entre os equipamentos utilizados, com a finalidade de aumentar e garantir a confiança na entrega dos resultados dos testes hematológicos, e consequentemente contribuir para o diagnóstico e prognóstico do paciente.

Abstract:
Brachycephalic obstructive airway syndrome (BOAS) is a conformation-related respiratory disorder of dog breeds with congenitally flattened facial and skull anatomy. BOAS is characterized by chronic shortness of breath and subsequent difficulty in exercising, a tendency to overheat, increased and abnormal respiratory noise, and low oxygen levels. The aim of our retrospective study was to inves-tigate the level of red blood cell distribution width (RDW), a biomarker of chronic hypoxemia, in groups of BOAS patients with different degrees of BOAS and a group of healthy non-brachycephalic dogs. Red blood cell distribution width provides information on the variability in the red blood cell volume. It is a simple and inexpensive variable included in the complete blood count report. Seventy-two BOAS patients and 24 non-brachycephalic dogs were included in this retrospective study. Pa-tients with BOAS were classified into grade 1 (13 dogs), grade 2 (27 dogs), and grade 3 (32 dogs) according to the severity of the disease. In our study, a significantly (p &lt; 0.05) higher RDW was found in all groups of BOAS patients compared to the non-brachycephalic dog group. However, we found no significant difference in RDW between the groups of BOAS patients. Thus, we may conclude that BOAS patients have increased variability in the size of red blood cells compared with healthy non-brachycephalic dogs. Our results warrant further studies to determine the potential utility of RDW in BOAS and to clarify the role of RDW in BOAS patients in relation to the severity of BOAS and cardiovascular risk.

Abstract:
Thyroid hormones play a crucial role in regulating metabolism and energy production. The cross-sectional study aimed to determine some hematological and hormonal parameters in thyroid dysfunctions patients. A total of 86 subjects were included in the study and grouped into three groups depend on thyroid stimulating hormone (TSH) concentration: Group 1 (12 healthy subjects as control), Group 2 (37 untreated hyperthyroid patients), Group 3 (Hypothyroid). Thyroid hormones, hematological parameters and hormonal parameters such as erythropoietin (EPO), leptin hormones and insulin-like growth factor-1 (IGF-1) were measured. The results of hematological analysis showed significant reduction in mean cell volume (MCV), mean cell hemoglobin (MCH), red cell distribution width (RDW) in hypothyroid patients as compared to control group. Significant decrease was seen in MCV and MCH in hypothyroidism patients as compared to hyperthyroidism patients. The absolute value of granulocyte increased significantly in hypothyroid patients as compared to hyperthyroid patients, but this increase was not significant as compared to control. Plateletcrit (PCT) significantly increased in hypothyroidism patients when compared to control. In conclusion this study revealed that serum erythropoietin (EPO) was decreased significantly in both hyperthyroidism and hypothyroidism compared to control. Moreover, significant decrease was observed in serum leptin and insulin-like growth factor-1 (IGF-1) in hypothyroidism patients as compared with control subjects.

Abstract:
Objetivo: Os autoanticorpos de aglutinina, imunoglobulinas predominantemente da classe IgM, interferem na interpretação da concentração dehemoglobina corpuscular média (CHCM) ao causarem aglutinação de eritrócitos em temperaturas abaixo de 37°C. Para eliminar essa interferência, as amostras são tradicionalmente aquecidas a 37°C por 15 minutos. Este estudo avaliou um método alternativo com menor tempo de banho. Método: Foram selecionadas 15 amostras com CHCM&gt;36 g/dL a 36,7°C, ponto de corte estabelecido pelo laboratório para a realização do banho a 37°C, e realizadas duas condições de banho: a 36°C por 15 minutos e a 56°C com imersões consecutivas, de 12 a 15 vezes. Conclusão: A mesma taxa de correção (73%) dos valores da concentração de hemoglobina corpuscular média foi encontrada tanto no banho a 37°C quanto no banho a 56°C. No entanto, algumas correções ocorreram em uma temperatura de banho que não foram observadas na outra. Um paciente não apresentou correção dos valores de concentração de hemoglobina corpuscular média em ambos os banhos, esta amostra apresentava esferócitos no esfregaço de sangue. Após a realização do teste t e da correlação de Pearson, observou-se que os maiores impactos, além da concentração de hemoglobina corpuscular média, ocorreram nos parâmetros: contagem de hemácias, Ht (hematócrito), HCM (hemoglobina corpuscular média) e RDW (Red Cell Distribution Width) de forma semelhante nas duas técnicas utilizadas. A utilização dessa técnica alternativa e o procedimento de banho a 56°C podem ser considerados como alternativas nos casos em que não houver resolução da interferência pelo método convencional. O presente estudo mostra-se importante com o intuito de guiar futuros estudos para melhor compreensão e estruturação da técnica, bem como aplicação com maior número de amostras, a fim de avaliar melhor o seu impacto.
