Benzaken,Adele Schwartz; Girade,Renato; Catapan,Elisa; Pereira,Gerson Fernando Mendes; Almeida,Elton Carlos de; Vivaldini,Simone; Fernandes,NeideABSTRACT Introduction and aim: Hepatitis C is a key challenge to public health in Brazil. The objective of this paper was to describe the Brazilian strategy for hepatitis C to meet the 2030 elimination goal proposed by World Health Organization (WHO). Methods: A mathematical modeling approach was used to estimate the current HCV-infected Brazilian population, and to evaluate the relative costs of two different ...
Hepatitis B viremia in HIV-coinfected individuals under antiretroviral therapy
Weissmann,Leonardo; Picone,Camila de Melo; Gouvêa,Michele Soares Gomes; Ferreira,Paulo Roberto Abrão; Viana,Mônica Salum Valverde BorsoiABSTRACT Background: Antiretroviral therapy (ART) has decreased AIDS incidence and mortality, rendering comorbidities, such as hepatitis B more relevant for people living with human immunodeficiency virus (HIV). Since antiretroviral drugs may also inhibit hepatitis B virus (HBV) replication, analyzing the impact of ART on management of hepatitis B in this population is important. Objective: To assess HBV viremi...
Characteristics of an outpatient chronic hepatitis B virus infection cohort
Assis,Danyenne Rejane de; Tenore,Simone de Barros; Pinho,João Renato Rebello; Lewi,David Salomão; Ferreira,Paulo Roberto AbrãoABSTRACT Objective: To characterize a chronic hepatitis B cohort based on initial and follow-up clinical evaluations. Methods: A retrospective and descriptive analysis of clinical and laboratory data from chronic HBsAg adult carriers, without HIV, unexposed to treatment, with at least two outpatient visits, between February 2006 and November 2012.

The clinical effectiveness of pegylated interferon and ribavirin for the treatm...
Ferreira,Paulo Roberto Abrão; Silva,Mariliza Henrique da; Brandão-Melo,Carlos Eduardo; Rezende,Rosamar Eulira; Gonzalez,Mário; Reuter,TâniaIntroduction: in Brazil, chronic hepatitis C in patients coinfected with the human immunodeficiency virus (HIV) is treated with pegylated interferon (Peg-IFN) and ribavirin (RBV). However, few studies have evaluated the effectiveness of this treatment in this particular population. The identification of the factors that predict sustained virological response (SVR) under current clinical practice would enable clin...
Disease burden of chronic hepatitis C in Brazil
Ferreira,Paulo Roberto Abrão; Brandão-Mello,Carlos Eduardo; Estes,Chris; Gonçales Júnior,Fernando Lopes; Coelho,Henrique Sérgio Moraes; Razavi,HomieBackground: Hepatitis C virus infection is a major cause of cirrhosis; hepatocellular carcinoma; and liver transplantation. The aim of this study was to estimate hepatitis C virus disease progression and the burden of disease from a nationwide perspective.Methods: Using a model developed to forecast hepatitis C virus disease progression and the number of cases at each stage of liver disease; hepatitis C virus-i...
Response predictors to treatment with pegylated interferon in chronic hepatitis B
Ferreira,Paulo Roberto Abrão; Tenore,Simone de BarrosThe clinical and epidemiological importance of chronic B hepatitis is currently unquestionable as a cause of end-stage liver disease and hepatocellular carcinoma. Recently, predictors of treatment response of this disease have been studied, both before and during the course of medication. Therapy stopping rules have been proposed, which may be useful in patients presenting poor treatment tolerance. This review ...
