Abstract:
Previous studies reported that the hepatitis C virus (HCV) could help disseminate the hepatitis D virus (HDV) in vivo through the unrelated hepatitis B virus (HBV), but with essentially inconclusive results. To try to shed light on this still-debated topic, 146 anti-HCV-positive subjects (of whom 91 HCV/HIV co-infected, and 43 with prior HCV eradication) were screened for anti-HDV antibodies (anti-HD), after careful selection for negativity to any serologic or virologic marker of current or past HBV infection. One single HCV/HIV co-infected patient (0.7%) tested highly positive for anti-HD, but with no positive HDV-RNA. Her husband, in turn, was a HCV/HIV co-infected subject with a previous contact with HBV. While conducting a thorough review of the relevant literature, the authors attempted to exhaustively describe the medical history of both the anti-HD-positive patient and her partner, believing it to be the key to dissecting the possible complex mechanisms of HDV transmission from one subject to another, and speculating that in the present case, it may have been HCV itself that behaved as an HDV helper virus. In conclusion, this preliminary research, while needing further validation in large prospective studies, provided some further evidence of a role of HCV in HDV dissemination in humans.

Abstract:
Introduction This study was conducted with an objective to analyze prevalence and risk factors associated with co-infection of hepatitis B virus (HBV) and hepatitis C virus (HCV) in HIV-positive patients with reference to their CD4+ T cell status. Materials and methods HIV-positive patients visiting the HIV clinic for CD4+ T cells testing at B.P. Koirala Institute of Health Sciences were tested for Hepatitis B and Hepatitis C. Data regarding age, gender, mode of HIV transmission, duration of HIV diagnosis, antiretroviral therapy status, antiretroviral therapy duration, hepatitis B or C status, and CD4+ T cells count were collected via face-to-face interview, and hospital records. The data were entered in Microsoft Excel 2019 v16.0 (Microsoft, WA, USA) and statistical analysis was performed by using statistical package for social sciences, IBM SPSS® v21 (IBM, Armonk, New York). Results Out of 474 HIV-positive patients, HIV-HBV, HIV-HCV, and HIV-HBV-HCV co-infections were seen in 2.95% (14/474), 18.14% (86/474), and 2.53% (12/474) respectively. The primary route of infection was intra-venous drug use (IVDU) in those co-infected with HBV only (8, 57.14%), HCV only (46, 53.49%), and both HBV and HCV (8, 66.67%). HIV patients infected via IVDU were 2.40 times more likely to have HIV-HCV co-infection as compared to those infected via sexual route (AOR 2.40, 95% CI: 1.49,3.86). Similarly, HIV patients with CD4+ T cells count less than 350 cells/mm3 were more likely to have HIV-HBV-HCV co-infection as compared to those with CD4 count equal to and more than 350 cells/mm3 (AOR 13.84, 95% CI: 2.90,66.10). Conclusion HIV-positive patients are at high risk of hepatitis B and/or hepatitis C co-infection. Intravenous drug use, and lower CD4+T cells count are the most important risk predictors of co-infection. All HIV-positive patients should be carefully screened with hepatitis B and hepatitis C tests during their follow-up.

Abstract:
Co-infection with hepatitis B and C is one of the major challenges in the management of HIV since access to antiretroviral drugs has improved in Africa. The aim of this study was to determine the seroprevalence HIV/Hep B and C co-infection in patients treated at the Al Nadjma multi-purpose centre in N'Djamena, Chad. This prospective study was conducted from June 2023 to May 2024 on 3,430 patients seen at the laboratory of the Al Nadjma multi-purpose Center in N'Djamena for screening for both HIV and hepatitis B and C. HIV was detected by immuno-chromatography using specific kits. The detection of hepatitis B and C by detection of HBsAg and HCV AC was carried out by immunochromatography using specific kits. The mean age of the patients was 38 years, with extremes of 18 and 60 years. Males were predominant (71.2%), with a sex ratio (M/F) of 1.22. The most common age was 31 to 40 (38.48%). The prevalence of HIV, hepatitis B and hepatitis C was 4.84%, 4.46% and 0.93% respectively. The prevalence of HIV/HBV, HIV/HCV and HIV/HBV/HCV co-infections was 4.17%, 0.79% and 0.09% respectively. This study shows that HIV and hepatitis B seroprevalence are high in N'Djamena. On the other hand, hepatitis C virus and HIV/HCV and HIV/HBV/HCV co-infections are relatively low compared with most of the data reported in other Sub-Saharan African countries. However, HIV/HBV co-infection could be considered a public health problem, requiring early diagnosis by organizing awareness and screening campaigns in the population, thus enabling better management of co-infected patients (HIV/HBV) by dual antiretroviral and anti-hepatitis B treatment.

Abstract:
Background/Aims: We report on the rates of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) in 1,313 clients entering heroin-assisted treatment (HAT) in Switzerland from 2003 to 2013. We identify predictors of HCV infection. Methods: Data were collected using questionnaires within 2 weeks of clients' first entry into HAT. Prevalence of HAV, HBV, HCV and HIV was calculated using laboratory test results collected at entry or using reports of older test results. Predictors of HCV status were identified through multiple logistic regression analysis. Results: Results show stable rates of HIV-positive clients and decreasing proportions of HAV- and HBV-infected clients. In 2013, there were 12% (n = 8) HIV-, 20% (n = 12) HAV-, 20% (n = 12) HBV- and 52% HCV- (n = 34) positive clients. Vaccination against HAV and HBV had become more frequent. Predictors of positive HCV status included older age, female gender, earlier year of entry, having spent 1 month or more in detention or prison, use of injected heroin and more years of intravenous use. Conclusion: Our results highlight the fact that efforts to prevent and test for infections and to promote vaccination against HAV and HBV in heroin users need to be continued.

Abstract:
Viruses of parenteral hepatitis HBV, HCV and human immunodeficiency (HIV) are characterized by similar transmission routes and risk groups, in which the probability of acquiring two or more of these infections at once is increased. The aim of the research is to study the prevalence and determine the genotypes of hepatitis B and C virus circulating among HIV-infected people. The results of the studies show a high prevalence of HCV markers (HCV – 45% and HBV- 16%) among HIV-infected people. Co-infected patients had high viral replication of HBV (60%) and HCV (62.7%). Аlso by molecular genetic method, HBV DNA was detected among HBsAg negative and HCV RNA in the absence of anti- HCV. Among those co-infected with HIV+HCV, genotype 1b of hepatitis C virus prevailed so the proportion of the total number was 45.7%. Among those co-infected with HIV+HBV, genotype D of the hepatitis B virus prevailed, which amounted to 70%. The genetic diversity of variants of hepatitis B and C viruses among HIV-infected people is similar to the diversity observed in the general population of the republic.

Abstract:
Background. Hepatitis B virus (HBV) infection remains a global public health problem. Objective – to analyze the prevalence of viral coinfections with human immunodefciency virus (HIV), hepatitis C virus (HCV), hepatitis delta virus (HDV), TT-viruses and SENV in patients with chronic hepatitis B (CHB) and to assess their influence on liver disease severity. Material and methods. The observational cross-sectional study included 287 patients with chronic hepatitis B virus (HBV) – those with monoinfection and coinfected with HIV, HCV, HDV. Routine hematological and biochemical tests were performed, serum HBV DNA level as well as liver fbrosis stage were measured. Blood samples from 62 patients for Torque teno virus (TTV), Torque teno mini virus, Torque teno midi virus, SENV (D and H genotypes) DNAs were examined by polymerase chain reaction. Results. Among patients with CHB the prevalence of coinfection HBV + HIV is 6.6%, HBV + HCV – 6.3%, HBV + HDV – 3.8% and HBV + HDV + HCV – 1.7%. CHB patients coinfected with HIV, HCV, HDV had more pronounced biochemical differences and higher proportion of liver cirrhosis vs. HBV-monoinfected ones. The detection rate of TT viruses and their various combinations in patients with CHB is 91.9%, SENV – 66.1%. Conclusion. Coinfection with HIV, HCV, HDV in CHB patients is associated with more severe forms of chronic liver disease as compared to HBV-monoinfection. TT viruses and SENV are widespread and don’t affect the severity of liver disease in patients with CHB.

Abstract:
Viral hepatitis is a global public health problem of epidemic proportions that caused 1.34 million deaths in 2015 a number comparable to deaths caused by tuberculosis and higher than those caused by HIV. Infection can be caused by the five known hepatitis viruses - A, B, C, D and E HAV, HBV, HCV, HDV and HEV . Many of these infections are preventable. Hepatitis B and C are responsible for 96 of overall hepatitis mortality. In India, the estimated burden of hepatitis is very high, necessitating focus on prevention and control measures to mitigate morbidity and mortality arising out of hepatitis.

Abstract:
Introduction HIV co-infection with hepatitis B (HIV-HBV) and hepatitis C (HIV-HCV) is known to affect treatment outcomes of antiretroviral therapy (ART); however, its magnitude is not well documented. We aimed to determine the magnitude of HIV-HBV and HIV-HCV co-infections simultaneously in people living with HIV (PLHIV) enrolled in ART care in Addis Ababa. Methods We reviewed the medical records of adults ≥15 years who were receiving ART care in three high burden hospitals in Addis Ababa. Baseline clinical and laboratory test results were extracted from medical records. Co-infection was determined based on hepatitis B surface antigen (HBsAg) and hepatitis C virus antibody (anti-HCV) tests obtained from the medical records. A multivariable logistic regression model was used to identify the risk factors for hepatitis B and C co-infections. Results A total of 873 HIV-positive participants were included in this study. The median age of the participants was 37.5 years, and 55.7% were women. Overall, HIV-HBV co-infection was 5.96% (95% CI: 4.56–7.74), and HIV-HCV co-infection was 1.72% (95% CI: 1.03–2.83). The multivariable logistic regression showed that the male sex was the most independent predictor for viral hepatitis B co-infection with an odds ratio of 2.42(95% CI:1.27–4.63). However, HIV-HCV co-infection did not show a significant association in any of the sociodemographic data of the participants. Conclusion HIV co-infection with hepatitis B was moderately high in individuals enrolled in ART care in Addis Ababa. Men had significantly higher HIV-HBV co-infection. HIV co-infection with hepatitis C was relatively low. Strengthening integrated viral hepatitis services with HIV care and treatment services should be emphasized to improve patient care in health facilities.

Abstract:
Background: Human immunodeficiency virus (HIV) positive population is at higher risk of getting infected with hepatitis B virus (HBV) or hepatitis C virus (HCV) or both. Co-infection with HBV/HCV may possibly complicate the clinical course of HIV in infected patients. Aim and objectives of the study were intended to determine clinical, haematological and biochemical profile of HIV patients co infected with hepatitis B and/or C.Methods: All consecutive patients presented with HIV infection who were coinfected with either Hepatitis B, C or both presenting to immunodeficiency or Gastroenterology OPD Base Hospital Delhi, were included in the study. It was a prospective, observational study.Results: HIV impacts the progression of HCV and increases the likelihood of subsequent liver damage as it is apparent in study by significant raised liver enzymes and hypoalbuminemia in HIV-HCV co infection compare to HIV–HBV. Conclusions: These coinfections are more common in younger and lesser educated people. Biochemical parameters could serve as pointers for early detection of liver disease as result of hepatitis co infections in HIV patients. Prompt diagnosis of HCV and HBV co-infection in HIV patients has both individual and public health benefits.

Abstract:
The cost effectiveness of using novel HCV treatment option, telaprevir and boceprevir, should depend on patients’ respond to conventional PEG-INFα and ribavirin therapy. The study of pharmacogenomics, interleukin-28B (IL-28B) polymorphisms, accompanied with the information of HCV genotypes are suggested to have the strongest predictive value of treatment outcomes and prognosis of disease in individuals infected with HCV who are undergoing conventional PEG-INFα and ribavirin therapy. It is extremely valuable in HCV/HIV co-infected patients as these groups of patients require a complex treatment regimen and demonstrate poor sustained viral response (SVR) rate. The development of a fast and promising IL-28B genotyping assay is urgently needed. A total of 47 blood samples randomly selected from HCV and HIV co-infected patients were used in this investigation. The aims of this study are to evaluate and compare the performance of newly developed IL-28B HybProbe real-time PCR assay using LightCycler® system against Sanger Sequencing method in determining IL-28B polymorphisms on rs12979860 and rs8099917 and to estimate the prevalence of IL-28B polymorphisms among HCV/HIV co-infected patients in Hong Kong. In addition, the genotypic distribution of HCV among the same patient group is identified by using in-house Sanger Sequencing method. It was found that the newly developed IL-28B real-time HybProbe assay resulted in 100% concordance with the traditionally used Sanger Sequencing method. The allele frequencies of C and T were 96% and 4% in rs12979860 and T and G were 97% and 3% in rs8099917 respectively. The CC and TT wild type are predominating in rs12979860 and rs8099917 with frequencies of 93.62% and 95.74% respectively. The most favorable compound genotype CC/TT with both homozygous wild types on both SNPs was the most predominant type with a high prevalence of 93.61%. Among all the samples, 50% samples were found to be HCV genotype 1, 41.18% were genotype 6 and 8.82% were genotype 3. A simple and efficient IL-28B real-time HybProbe assay was developed in this study and proved to show excellent performance on IL-28B genotyping although further optimization is suggested before it can be applied in the clinical setting. The favourable wild type genotypes of rs12979860 and rs8099917 accounted for the most predominant genotypes which is similar to other findings obtained from an Asian population. A comparatively high prevalence of HCV genotype 6 was found in the HCV/HIV co-infected group. Future study with the information of treatment outcomes (HCV viral load) can further evaluate the predictive value of IL-28B polymorphisms on SVR in different HCV genotypes.<br>published_or_final_version<br>Medical Sciences<br>Master<br>Master of Medical Sciences

Abstract:
Hepatitis C (HCV) infection is associated with high rates of mortality and morbidity. Interferon alpha based treatment for HCV offers a good rate of viral clearance, however the associated neuropsychiatric side effects increase the risk of treatment interruption and disease progression. The HIV/HCV coinfection is of particular interest due to association with higher rates of HCV treatment side effects and earlier treatment discontinuation when compared with HCV mono-infection. Therefore, the aim of the thesis was to further explore the effect of coinfection on mood and cognition and how HCV interferon based treatment influences neuropsychiatric side effects in mono and co-infected samples. Firstly a meta-analysis was performed to explore cognitive impairment and depression in HIV HCV co-infection. The results suggested that there was consistent literature indicating that the coinfected group were more cognitively impaired and more likely to be depressed than the HCV and HIV monoinfected groups. Secondly empirical studies were conducted to analyse the profile of depression during interferon-based treatment, and explore potential risk factors, such as gender and immune profile. Co-infected patients appeared less vulnerable to the emergence of depressive symptoms during HCV treatment than HCV mono-infected patients. Additionally, neither female gender nor immune response were associated with increased vulnerability to depression. Finally, a longitudinal study investigating cognitive performance during interferon-based treatment was conducted. A significant effect of treatment on information processing speed level of executive function was observed. Overall the research reported in this thesis further clarifies the nature of interferon induced depression and cognitive effects differences between mono and coinfected groups. Having identified a neurovegetative symptom profile and speed of processing impairment of executive function during HCV treatment, the discussion considers the potential of targeted interventions via psychotropic medication and cognitive interventions to minimise the impact of these treatment effects and optimise outcomes in this clinical group.

Abstract:
A hepatite C, causada pelo vírus da hepatite C (HCV), afeta milhões de pessoas no mundo. A transmissão do HCV é semelhante ao HIV, justificando a alta taxa de prevalência da coinfecção. Pacientes coinfectados HCV/HIV apresentam maior taxa de progressão da fibrose hepática e da mortalidade, em comparação aos pacientes monoinfectados com HCV. Assim, o estudo de genes e/ou moléculas que controlam a resposta imune é pertinente. No presente estudo, avaliamos o papel do antígeno leucocitário humano G (HLA-G), molécula com reconhecida atividade imunomoduladora, capaz de inibir a ativação das células T e a atividade citotóxica das células Natural Killers (NK) e linfócitos T CD8+, além de induzir a formação células T reguladoras. Nós investigamos 216 pacientes monoinfectados pelo HCV, 135 pacientes coinfectados HCV-HIV e 152 indivíduos não infectados. A variabilidade do gene HLA-G foi avaliada por sequenciamento de Sanger e a expressão hepática da molécula por imunoistoquímica. A expressão de HLA-G foi observada somente no tecido hepático dos pacientes, principalmente nos hepatócitos. O aumento de expressão de HLA-G foi associado com avanço da fibrose e da atividade necroinflamatória no fígado de ambos os grupos de pacientes. Idade igual ou superior a 40 anos e a cor de pele não-branca também foram associados com aumento da expressão hepática da molécula nos pacientes HCV. Outros fatores do hospedeiro analisados como gênero e genótipo do HCV não foram associados com o nível de expressão de HLA-G no fígado. A frequência do alelo HLA-G*01:01:01:01 estava aumentada nos pacientes HCV e do alelo G*01:05N diminuída nos pacientes coinfectados HCV-HIV, porém, não houveram associações significantes entre a variabilidade genética de HLA-G e a expressão hepática de HLA-G. O presente estudo contribui para a ampliar os conhecimentos acerca da participação da molécula HLA-G na hepatite C crônica, associado ou não com infecção pelo HIV.<br>Hepatitis C, caused by the hepatitis C virus (HCV), affects millions of people worldwide. The transmission of HCV is similar to HIV, which explains the high prevalence of coinfection. HCV-HIV coinfected patients have higher rate of liver fibrosis progression and mortality when compared to HCV monoinfected patients. Thus, the study of genes and/or molecules that control the immune response is relevant. In the present study, we evaluated the role of human leukocyte antigen G (HLA-G), a molecule known by its immunomodulatory activity, which is capable to inhibit T cell activation and cytotoxic activity of natural killer (NK) cells and CD8+ T cells, in addition to inducing the formation of regulatory T cells. We studied 216 HCV patients, 135 HIV-HCV coinfected patients and 152 uninfected individual. The variability of the HLA-G gene was evaluated by Sanger sequencing and the hepatic expression of the molecule by immunohistochemistry. The HLA-G expression was observed only in liver tissue of patients, mainly in hepatocytes. The increased HLA-G expression was associated with increased liver fibrosis and necroinflammatory activity in both groups of patients. The age greater than or equal to 40 years and the non-white skin color were also associated with increased hepatic expression of the molecule in the HCV patients. Other host factors analyzed as gender and HCV genotype were not associated with the level of HLA-G expression in the liver. The frequency of HLA-G*01:01:01:01 allele was increased in HCV patients and G*01:05N decreased in HCV-HIV coinfected patients, however, there was no significant association between the genetic variability of HLA-G and HLA-G liver expression. The present study contributes to expand the knowledge regarding the participation of HLA-G in chronic C hepatitis, associated or not with the HIV infection.

Abstract:
Após anos de debates, o teste de detecção de ácidos nucleicos (NAT) para HIV e HCV na triagem de sangue foi implementado de forma obrigatória no Brasil em 2013, e HBV, em 2016. Um dos motivos citados sobre o atraso em sua implementação foi o custo elevado que seria adicionado à sorologia e, até o momento, uma ampla avaliação econômica em saúde (AES) a respeito de sua eficiência no país não está disponível. Diversos artigos já demonstraram que a razão incremental de custo-utilidade (ICUR) do NAT em relação à sorologia varia de 0,21 a 8,84 milhões de dólares americanos (US$) para cada QALY ganho. Esta grande variação dá-se, principalmente, por diferenças entre a idade média dos receptores de sangue (RS), incidência/prevalência dos vírus entre os doadores de sangue (DS), custo dos testes e tratamentos médicos, cobertura da vacina contra o HBV e sensibilidade do teste utilizado. Assim, faz-se necessária uma avaliação abrangente desta tecnologia e sua efetividade para o cenário brasileiro. Objetivos: Realizar uma revisão sistemática (RevS) de estudos econômicos completos sobre o uso do NAT para HIV, HCV e/ou HBV no mundo; realizar a AES sobre o NAT sob a perspectiva pública brasileira; caracterizar as doações de sangue em janela imunológica no país. Métodos: Metodologia Cochrane de RevS das bases de dados Medline, Embase, LILACS, CRD, BVS ECO, Google Scholar e IDEAS; questionário aplicado aos bancos de sangue e modelo econômico on-line da International Society of Blood Transfusion (ISBT) para cálculo da ICUR do \"NAT em mini-pool de seis amostras individuais\" (MP6) versus \"testes sorológicos\" (SR) no Brasil. Resultados: Quatorze estudos de dezesseis diferentes países foram avaliados. O NAT apresentou a maior relevância nos países de baixa renda, onde há as maiores prevalências e incidências virais, menores taxas de doadores de repetição (DR) e RS mais jovens. A maioria dos estudos concluiu que o NAT, independente do vírus analisado, não é custo-efetivo. As principais diferenças entre as características dos estudos foram relacionadas aos custos médicos e idade dos RS. O maior desvio dos padrões de uma RevS foram: não incluir o racional para definição dos desfechos e o modelo utilizado e não ter claro o conflito de interesse dos autores; para esta AES, o MP6 versus SR apresentou um ICUR de US$ 231.630,00/QALY, ou seja, 26,2 vezes o PIB per capita nacional) e um ICER de US$ 330.790,00/Ano de vida ganho (AVG). A análise de sensibilidade univariada do modelo demonstrou que somente a taxa de desconto, idade do RS, custo do NAT e epidemiologia dos vírus alteraram de forma significativa o ICUR obtido, variando desde US$ 76.957,00/QALY a US$ 933.311,00/QALY; a maioria dos casos de janela imunológica no Brasil são jovens, média de 29 anos, do sexo masculino, com pelo menos o ensino médio completo e mesmo com a obrigatoriedade do Anti-HBc no Brasil, o NAT-HBV é o que apresentou o maior rendimento. Conclusões: Os jovens, principalmente, ainda buscam os bancos de sangue como locais de testagem após comportamento de risco e é de extrema importância a revisão do custo real e completo do teste NAT no Brasil para ampla abordagem da tecnologia nacional incorporada e, se necessário, revisar a forma e modelo de reembolso da mesma e permitir a defesa do bem-estar da população e do bem público.<br>After years of discussion, nucleic acid (NAT) testing in the blood screening for HIV and HCV was implemented in Brazil in 2013 and HBV in 2016. One of the reasons cited for the delay in its implementation was the high cost that would be added to serology screening and a comprehensive economic assessment of its efficiency in the country is not yet available. Several articles have already shown that the incremental cost-utility ratio (ICUR) of NAT versus serology ranges from 0.21 to 8.84 million American dollars (US$) for each QALY gained. This large variation is mainly due to differences between the mean age of the blood recipient, viruses\' incidence / prevalence among donor population, cost of medical tests and treatments, HBV vaccine coverage, and sensitivity of the test used. Thus, a comprehensive evaluation of this technology and its effectiveness under the perspective of the Brazilian public health system (SUS) is needed. Objectives: Development of a systematic review (RevS) of complete economic studies about the use of NAT for HIV, HCV and / or HBV in the world. Conduct an economic evaluation of NAT under SUS perspective; characterize Brazilian blood donations in the serology \"window period\". Methods: Cochrane RevS Methodology of the Medline, Embase, LILACS, CRD, CRD ECO, Google Scholar and IDEAS databases; Questionnaire applied to blood banks and online economic model from the International Society of Blood Transfusion (ISBT) to calculate the ICUR for \"NAT in mini-pool of six individual samples\" (MP6) versus \"Serology Tests\" (SR) in Brazil. Results: Fourteen studies from sixteen different countries were assessed. NAT was most relevant in low-income countries, where there are the highest prevalences and viral incidences, lower rates of repeat donors and younger recipients of blood (RS). Most of the studies concluded that NAT, regardless of the virus evaluated, is not cost-effective. Differences in the characteristics of the studies were related to the costs and age of RS. The major deviations from RevS standards were: not including the rationale for selecting the outcomes and the model used and not being clear about the authors\' conflict of interest; MP6 vs SR showed an ICUR of US$ 231.630,00/QALY, 26,2 times Brazilian GND per capita) and an ICER of US$ 330.790,00/Life year gained (AVG). The univariate sensitivity analysis of the model demonstrated that only changes on discount rate, NAT cost, RS age and viruses\' epidemiology significantly altered the ICUR in a range between US$ 76.957,00/QALY and US$ 933.311,00/QALY; Most RS window period cases in Brazil are young, average of 29 years old, male, with at least high school education completed and even with the requirement of Anti-HBc in Brazil, NAT-HBV is the one that presented the highest yield. Conclusions: Young people, mainly, still seek blood banks as testing sites, especially after a risk behavior. It is extremely important to reveal the real and complete cost of the Brazilian NAT to fully evaluate its efficiency and, if needed, reassess its current reimbursement model, allowing the wellbeing defense of the population and public interest.

The advent of potent antiretroviral therapy has resulted in a significant reduction in the incidence of opportunist infections, and thus greater life expectancy for HIV positive patients. However, the liver disease appears as a major cause of morbidity and mortality among these patients, especially those related to hepatitis C virus. Co-infection with HCV/HIV induces a worse prognosis for both infections, which may lead to the development of AIDS, a faster rapid evolution to chronic active hepatitis and / or liver cirrhosis and death. This study aimed to investigate the epidemiology and molecular profile HCV infection in HIV-infected individuals with no prior antiretroviral therapy, seen in the referral hospital for the treatment of infectious diseases (Hospital for Tropical Diseases - Anuar Auad / HDT) in Goiania, Goiás. A total of 505 treatment naïve individuals and were referred to the HDT, from April 2009 to April 2010 were interviewed and underwent blood collection. All sera were tested for antibodies to HCV (anti-HCV) and for HCV RNA by polymerase chain reaction (PCR). Genotyping was performed by reverse hybridization by the Line Probe Assay (LiPA) method. The prevalence of anti-HCV was 4.6% (95% CI: 3.0 to 6.8). The viral RNA was detected in 65.2% (15/23) of anti-HCV positive samples. The genotypes identified were 1 (subtypes 1a and 1b) and 3 (subtype 3a). The age > 40 years, living in other states or Goiania city, surgery, injecting and non-injecting drug and anti-HBc positive (antibody to core antigen of hepatitis B virus) were associated with HCV infection after logistic regression. The data presented shows the vulnerability of the HIV sropositive population to acquisition of infectious diseases such as HCV infection. Thus, the information obtained will be essential for planning public health interventions, preventing and control of hepatitis C in this population.<br>Os vírus da hepatite C (HCV) e da imunodeficiência humana (HIV) causam infecções crônicas no hospedeiro. O advento da terapia antiretroviral potente trouxe uma redução da incidência de infecções oportunistas, e consequentemente, uma maior expectativa de vida aos pacientes HIV soropositivos. No entanto, as hepatopatias surgem como uma das principais causas de morbimortalidade entre esses pacientes, principalmente aquelas relacionadas ao vírus C. A coinfecção HCV/HIV induz a um pior prognóstico de ambas as infecções, podendo levar ao desenvolvimento da Aids, evolução mais rápida para hepatite crônica ativa e/ou cirrose hepática e morte. Este estudo teve como objetivo investigar o perfil epidemiológico e molecular da infecção pelo HCV em indivíduos infectados pelo HIV, sem tratamento antiretroviral prévio, atendidos no Hospital de referência para o tratamento de doenças infecciosas (Hospital de Doenças Tropicais - Anuar Auad / HDT) em Goiânia, Goiás. Um total de 505 indivíduos, virgens de tratamento, encaminhados ao HDT, no período de abril/2009 a abril/2010, foram entrevistados e submetidos à coleta de sangue. As amostras (soros) foram testadas para a detecção de anticorpos para o HCV (ELISA/LIA) e submetidas à identificação do RNA-HCV pela reação em cadeia da polimerase (PCR). A genotipagem foi realizada por hibridização reversa, pelo método Line Probe Assay (LiPA). A prevalência para anti-HCV foi de 4,6% (IC 95%: 3,0-6,8). O RNA viral foi detectado em 15 amostras, sendo todas elas anti-HCV positivas. Foram identificados os genótipos 1 e 3, com predomínio do subtipo 1a, seguido dos subtipos 1b e 3a. As variáveis idade superior a 40 anos, ser procedente de Goiânia ou outros estados, cirurgia, uso de drogas injetáveis e não-injetáveis, história de prisão e positividade ao anti-HBc foram associados à infecção pelo vírus da hepatite C, após regressão logística. Os dados apresentados revelam a vulnerabilidade da população HIV soropositiva à aquisição de doenças infecciosas como a infecção pelo HCV. Assim, as informações obtidas serão essenciais para o planejamento de ações de saúde pública para a prevenção e controle da hepatite C nessa população.

Abstract:
Introdução: A hepatite C é um problema de saúde pública, com maior prevalência em pacientes com doença renal crônica. Objetivo: Conhecer a relação do vírus da hepatite C em pacientes hemodialisados. Métodos: Foi realizada uma revisão bibliográfica, com abordagem qualitativa. A busca artigos ocorreu em março de 2019. Foram selecionados artigos no idioma de português e inglês, extraídos de sites de coleção como LILACS, SciELO, PubMed, EBSCO e Ministério da Saúde, no período de 2009-19 e utilizados os seguintes descritores em português: HCV, hepatite C, hemodiálise, doença renal, diálise. E, em inglês: hepatitis c, hemodialysis, renal disease, dialysis. Ao todo, neste estudo foram incluídos oito artigos. Resultados: A hepatite C é causada por um vírus com genoma de fita simples ácido ribonucleico, envelopado, com um diâmetro que varia de 55 a 65 nm, da família Flaviviridae, do gênero Hepacivirus. O Brasil registrou 24.460 casos de hepatite C em 2017, sendo Porto Alegre (RS) a capital com as maiores taxas (90,7 casos/100 mil habitantes). A proporção de infecções por via sexual foi de 9,2%, relacionadas ao uso de drogas, 8,1%, e as infecções por via transfusional, 6,8%. Pacientes com a doença renal crônica são predispostos a contaminação pelo vírus. As principais formas de contágio de pacientes em hemodiálise têm sido as diversas transfusões sanguíneas, resultados falso-negativos, fazendo uma disseminação por equipamento, objetos compartilhados pelos pacientes e quebra de biossegurança dos próprios profissionais. O teste de hepatite C deve ser feito em todos os pacientes que iniciarem o programa de hemodiálise, com confirmação utilizando-se os testes moleculares. Conclusão: A infecção em pacientes com doença renal crônica em hemodiálise vem aumentando ao longo do tempo. Fazem-se necessários maiores cuidado e prevenção nos centros de hemodiálise para que haja redução da contaminação pelo vírus da hepatite C em pacientes com doença renal crônica.

Abstract:
INTRODUCTION Sexually transmitted infections (STI’s) are a public health threat. Syndromic approaches based on clinical symptoms have been suggested as having poor diagnostic performance, particularly in the type of settings where MSF is operational. We assessed the burden of STI’s and the diagnostic performance of a syndromic approach within an MSF-supported HIV/STI project in Eswatini. METHODS We conducted a cross-sectional study, enrolling adults accessing routine HIV testing and antiretroviral care services in six clinics in Shiselweni, from July 2022 to January 2023. HIV testing counselors performed HIV testing and nurses assessed patients for STI’s. Laboratory investigations included antibody-based rapid diagnostic tests (RDT’s) for Treponema pallidum (TP), hepatitis B (HBV) and hepatitis C (HBC). The molecular platform Xpert was used to test urine samples for Chlamydia trachomatis (CT), Neisseria gonorrhoea (NG), Trichomonas vaginalis (TV), Mycoplasma genitalium (MG), vaginal/anal swabs for human papillomavirus (HPV), and plasma for HIV viraemia to test for acute HIV infection (HIV). We calculated the prevalence of STI’s, and assessed diagnostic performance of a syndromic approach to diagnose male urethritis (MUS) and vaginal discharge (VDS) syndromes, versus laboratory-based testing. ETHICS This study was approved by the Eswatini Health and Human Research Review Board and by the MSF Ethics Review Board. RESULTS Of 1,041 study participants, 682 were women (65.5%), and the median age was 30 (interquartile range, IQR, 24-38) years. Overall, 280 (26.9%) were known HIV-positive and of 755 with unknown HIV status, 30 (4.0%) were newly diagnosed with HIV, of whom seven (23.3%) had AHI. 308 (29.6%) patients had at least one of the following three pathogens identified: NG 121 (11.6%); CT 155 (14.9%); TV 109 (10.5%). MG was detected in 33/330 participants (10.0%). In addition, 105 (10.1%) had antibodies against TP, 49 (4.7%) against HBV, and three (0.3%) against HCV. HPV prevalence was higher in tested women (104/196; 53.1%) versus men (5/27; 18.5%; p=0.001). Prevalence of NG/CT/TP was highest in newly-diagnosed HIV cases (48.2%) versus known HIV-positive cases (26.8%, p=0.019). Based on the syndromic approach, 188/634 (29.7%) had a VDS, and 97/334 (29.0%) a MUS. Diagnostic performance of the syndromic approach was better in men (MUS: sensitivity: 66.7%, specificity 87.5%; positive predictive value, PPV, 70.1%, negative predictive value, NPV, 85.7%), versus women (VDS: sensitivity 35.9%, specificity 72.9%; PPV 35.1%, NPV 73.5%). CONCLUSION A high burden of STI’s in Eswatini and poor diagnostic ability of the syndromic approach in this setting, calls for new approaches for STI care in MSF-supported sexual and reproductive health programmes in resource-poor settings.

Abstract:
Early detection and treatment of sexually transmitted infections, HIV, and hepatitis B and C are vital to minimise the harm they cause. This Evidence Check aimed to identify effective initiatives that engage and support GPs and the GP clinic workforce in NSW to increase testing for these conditions. It also aimed to identify effective modifications to practice management software to increase GP engagement in screening and care for these conditions. Sixty-two articles were found in total. The most effective initiatives used multiple interventions, particularly provider education and quality improvement. They involved both GPs and other health workers, and offered clinic-level initiatives to help identify patients at higher risk (e.g. software-generated alerts) and engage them in testing (e.g. through self-collected specimens). Models of care that used nurse-led testing or links to specialist services offered a way to increase capacity to carry out testing. The quality of evidence was mixed—there were few randomised controlled trials, and little evidence about the sustainability of the initiatives over time, highlighting the need for further high-quality research.

Abstract:
The objective of this study was to track trends in the signs of higher-quality addiction treatment as defined by the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Addiction, and the Substance Abuse and Mental Health Services Administration. We analyzed the National Survey of Substance Abuse Treatment Services from 2007 through 2017 to determine the percent of facilities having the characteristics of higher quality. We analyzed the percent by state and over time. • We found improvements between 2007 and 2017 on most measures, but performance on several measures remained low. • Most programs reported providing evidence-based behavioral therapies. • Half or fewer facilities offered medications for opioid use disorder; mental health assessments; testing for hepatitis C, HIV, and sexually transmitted diseases; self-help groups; employment assistance; and transportation assistance. • There was significant state-level variation across the measures.

Abstract:
Hepatitis B virus (HBV) infection is a major public health problem, with more than 400 million HBV carriers estimated worldwide. Chronic HBV infection is associated with a diverse clinical spectrum of liver damage ranging from asymptomatic carrier status, chronic hepatitis, cirrhosis, and hepatocellular carcinoma (HCC). There have been increasing lines of evidence to indicate influences of HBV genotypes and mutations on the outcome of liver disease, particularly the development of HCC. The project is aimed to study the prevalence and clinical significance of genotypes and mutations in Precore/core and X regions of HBV in Thai patients. Our study demonstrate that genotype C and B were the predominant strains, accounting for approximately 75 and 20% of patients, respectively. Patients with HBV genotype C, compared to those with genotype B, had a higher positive rate of HBeAg and exhibited earlier progression of cirrhosis and HCC. However, there was no difference in the risk of developing HCC and its prognosis between patients with genotypes B and C. Furthermore, certain X gene mutations and, particularly, CP mutations in young patients may contribute to the development of HCC As the genetic variability of HBV differs geographically and the data available in Thailand are still limited, our study will provide useful information regarding the epidemiology and clinical relevance of HBV genotypes and mutations in Thai populations.
