1. Qual a conduta após teste rápido positivo para hepatite C?
Deve-se solicitar o exame de carga viral do HCV (HCV-RNA, realizado por técnica de PCR (polymerase chain reaction) para confirmar a infecção pelo vírus da hepatite C.
O teste rápido dosa o próprio anti-HCV com excelente acurácia, não sendo necessária sua repetição por outro método. Pacientes com anti-HCV reagente por método tradicional

2. GENES EXPRESSION AND SERUM BIOMARKERS FOR DIAGNOSIS OF HEPATOCELLULAR CARCINOMA, CIRRHOSIS AND HEPATITIS C
RESUMO Contexto: Carcinoma hepatocelular (CHC) é o tipo mais comum de câncer de fígado. Os fatores de risco para CHC incluem infecção pelo vírus da hepatite C (VHC) e B (VHB), cirrose alcoólica e alterações genéticas que podem afetar diversas vias celulares. Objetivo: Este estudo teve como objetivo analisar a expressão gênica e proteica sérica

3. IMMUNOHISTOCHEMICAL ASSESSMENT OF LYMPHATIC VESSELS IN HUMAN LIVERS WITH CHRONIC HEPATITIS C - RELATION TO HISTOLOGICAL VARIABLES
RESUMO Contexto A hepatite C é um relevante problema de saúde pública. A doença pode permanecer clinicamente silenciosa tanto na forma aguda como na crônica e as infecções crônicas podem progredir para doenças avançadas, tais como cirrose e carcinoma hepatocelular (CHC), requerendo tratamentos dispendiosos, comprometendo a qualidade de vida do pac

4. Causes of death and mortality trends related to hemophilia in Brazil, 1999 to 2016
ABSTRACT Introduction Multiple cause of death methodology enhances mortality studies beyond the traditional underlying cause of death approach. Aim: This study aims to describe causes of death and mortality issues related to haemophilia with the use of multiple-cause-of-death methodology. Methods: Annual male haemophilia mortality data was extracted from

6. [PROVISIONAL] Resistance mutations of NS3 and NS5b in treatment-naïve patients infected with Hepatitis C virus in Santa Catarina and Rio Grande do Sul States, Brazil
Abstract Hepatitis C virus (HCV) infection is a worldwide health problem. Nowadays, direct-acting antiviral agents (DAAs) are the main treatment; however, the high level of variability of HCV lead to development of resistance-associated variants (RAVs). Thus, look into the RAVs among infected patients is an important tool for monitoring the efficacy of the t

7. Molecular epidemiology of Hepatitis delta virus infection in Minas Gerais state from Brazil, an area outside the hyperendemic region of the Amazon Basin
BACKGROUND Hepatitis delta virus (HDV) infections in hepatitis B virus (HBV) carriers are the most severe form of viral hepatitis. HDV prevalence is high in the Brazilian Amazon, but studies in other regions of the country are still scarce and often underestimated its prevalence by including a small numbers of individuals. OBJECTIVE This study aimed to de

8. Phylogenetic analysis and genotype distribution of Hepatitis B Virus (HBV) in Roraima, Brazil
ABSTRACT Hepatitis B virus (HBV) infection is a serious global health problem. HBV has a high viral genetic diversity, with 10 genotypes recognized. In Brazil, the Roraima State is the third in the Northern region regarding the number of hepatitis B cases. On the other hand, few data on HBV genotyping and phylogenetic analysis are available. The purpose of t

9. Atypical crusted scabies in a patient with chronic liver disease caused by hepatitis B and D viruses
Abstract: Crusted scabies is a less common variant of scabies that is highly contagious, difficult to treat and involves infestation by Sarcoptes scabiei var. hominis. The classical clinical presentation includes crusted, scaly and generally non-pruritic lesions usually located on the head, neck, palmar, plantar and periungual region. It was first described

10. Prevalence of Hepatitis B and C virus infection among alcoholic individuals: importance of screening and vaccination
ABSTRACT Drug users have been reported to have an increased risk for acquisition of viral hepatitis. This study aims to evaluate the prevalence of HBV and HCV infection and usefulness of saliva for HBsAg and anti-HCV detection in alcoholic patients.A total of 90 alcoholic patients were recruited in 2013. HBsAg and anti-HCV were tested in serum and saliva, an

11. Distribution of HBV subgenotypes in Ribeirão Preto, Southeastern Brazil: a region with history of intense Italian immigration
Abstract Hepatitis B virus (HBV) is distributed worldwide, with geographical variations regarding prevalence of the different genotypes. The aim of this study was to determine the HBV genotypes and subgenotypes circulating in Southeast Brazil and compare the genetic sequences found with HBV sequences previously described in the world. Sequences from 166 chro

12. Detection and molecular characterisation of a diagnosis escape variant associated with occult hepatitis B virus in Brazil
BACKGROUND Many studies have identified mutations in the hepatitis B surface antigen (HBsAg) as important factors limiting the ability of commercial serological assays to detect this viral antigen. However, an association between mutations in the HBsAg gene and the occurrence of occult HBV infection (OBI) in patients has not been established. OBJECTIVES
