          Abstract

          ABSTRACT Introduction: Infections caused by the hepatitis B virus (HBV) and hepatitis C virus (HCV) are a major public health problem. Objectives: The study aimed to detect HBsAg, anti-HBc, anti-HBs and anti-HCV among health professionals and users of the Brazilian Unified Health System [Sistema Único de Saúde (SUS)] in the city of Resende, Rio de Janeiro, and to describe the sociodemographic profile and background of exposure. Methods: A total of 585 samples were collected between May and June 2014, obtained from the Brazilian Notifiable Diseases Surveillance System [Sistema de Informação de Agravos de Notificação (SINAN)] data, which were tested for HBsAg, anti-HBc, anti-HBs and anti-HCV. Results: The predominant age group observed was 30-44 years (n = 277; 47.3%), 54.87% (n = 321) were female and 271 (46.32%) self declared skin colour/ethnicity white. The married participants were 262 (44.78%), 42.22% graduated from high school (n = 247) and 174 were health professionals (29.74%). Four participants were anti-HCV reagents and 18 were anti-HBc reagents. From these, 15 participants were reactive for anti-HBs antibodies. Among health professionals, 68.8% were anti-HBs positive. And 63.9% of participants declared to be vaccinated against hepatitis B. Conclusion: The prevalence of 0.68% for HCV and 3.08% for anti-HBc are below that detected in the Southeast region from the last census in the capitals of Brazil. There is still a reduced acceptance among health professionals for HBV and HCV screening.

          RESUMO Introdução: As infecções causadas pelo vírus da hepatite B (VHB) e C (VHC) constituem grave problema de saúde pública. Objetivos: O estudo visou detectar os marcadores HBsAg, anti-HBc, anti-HBs e anti-VHC em profissionais de saúde e usuários do Sistema Único de Saúde (SUS) no município de Resende, Rio de Janeiro, bem como descrever o perfil sociodemográfico e os antecedentes de exposição. Métodos: Foram avaliadas 585 amostras entre maio e junho de 2014, obtidas dos dados do Sistema de Informação de Agravos de Notificação (SINAN). Elas foram testadas para HBsAg, anti-HBc, anti-HBs e anti-VHC. Resultados: A faixa etária predominante observada foi de 30-44 anos (n = 277; 47,3%); 54,87% (n = 321) eram do sexo feminino e 271 (46,32%) se autodeclararam de cor da pele/etnia branca. Os participantes casados foram 262 (44,78%); 42,22% tinham o ensino médio (n = 247) e 174 eram profissionais de saúde (29,74%). Quatro participantes eram anti-VHC reagentes e 18, reagentes para anti-HBc. Destes, 15 eram anti-HBs reagentes (aHBs+). Nos profissionais de saúde, 68,8% possuem aHbs+. Em relação à vacinação contra hepatite B, 63,9% declararam possuí-la. Conclusão: As prevalências 0,68% de VHC e de 3,08% de anti-HBc estão abaixo da detectada na região Sudeste no último censo nas capitais do Brasil. Há ainda reduzida adesão dos profissionais de saúde à testagem para VHB e VHC.

          Epidemiology of hepatitis B and C viruses: a global overview.

          This article reviews the prevalence, disease burden, genotype distribution, and transmission patterns of hepatitis B virus (HBV) and hepatitis C virus in the 6 World Health Organization regions. The global epidemiology of hepatitis B and C demonstrates a predominantly declining prevalence of the diseases. Improvement in the control of hepatitis B has been largely achieved with implementation of a more universal HBV vaccine program, although a large gap still remains in the effort toward global prevention of hepatitis B. The transmission of hepatitis C has been greatly impacted by mandatory screening of blood donors in most countries in the world, although intravenous drug use continues to be a major source of infection. Public education regarding the risks of exposure to infected paraphernalia as well as household items such as razors is necessary in the continuing effort to curb this disease. (c) 2010 Elsevier Inc.

            Natural history of acute and chronic hepatitis C.

            Hepatitis C virus (HCV) infection remains a major global health burden. Hepatitis C causes significant liver-related morbidity and mortality due to hepatic decompensation and development of hepatocellular carcinoma. In addition, extra-hepatic manifestations of hepatitis C are frequent. There is a very large interindividual variability in the natural history of both acute and chronic hepatitis C which can be explained in part by a combination of various host, viral and environmental factors. Successful antiviral treatment can prevent short- and long-term complications of HCV infection in many patients. Still, the relative contribution of distinct risk factors for disease progression in different phases of HCV infection needs to be better defined. Personalized treatment approaches for HCV infection should consider individual risk profiles to avoid both under- and over-treatment - which will remain important also in upcoming era of interferon-free treatment of hepatitis C.

              Epidemiology and natural history of hepatitis C virus infection.

              Hepatitis C virus (HCV) affects 130-210 million people worldwide and is one of the major risk factors for hepatocellular carcinoma. Globally, at least one third of hepatocellular carcinoma cases are attributed to HCV infection, and 350000 people died from HCV related diseases per year. There is a great geographical variation of HCV infection globally, with risk factors for the HCV infection differing in various countries. The progression of chronic hepatitis C to end-stage liver disease also varies in different study populations. A long-term follow-up cohort enrolling participants with asymptomatic HCV infection is essential for elucidating the natural history of HCV-caused hepatocellular carcinoma, and for exploring potential seromarkers that have high predictability for risk of hepatocellular carcinoma. However, prospective cohorts comprising individuals with HCV infection are still uncommon. The risk evaluation of viral load elevation and associated liver disease/cancer in HCV (REVEAL-HCV) study has followed a cohort of 1095 residents seropositive for antibodies against hepatitis C virus living in seven townships in Taiwan for more than fifteen years. Most of them have acquired HCV infection through iatrogenic transmission routes. As the participants in the REVEAL-HCV study rarely receive antiviral therapies, it provides a unique opportunity to study the natural history of chronic HCV infection. In this review, the prevalence, risk factors and natural history of HCV infection are comprehensively reviewed. The study cohort, data collection, and findings on liver disease progression of the REVEAL-HCV study are described.
