A Study of the Association between Diabetes Mellitus and Chronic Hepatitis B Virus Infection

West Indian med. j; 68 (2), 2019
ABSTRACT Background: Hepatitis B virus (HBV) infection and diabetes mellitus are major health problems associated with significant morbidity and mortality. The published literature suggests an association of diabetes mellitus with liver disease. However, the role of HBV infection in diabetes aetiology i...

Serum regucalcin is a useful indicator of liver injury severity in patients with hepatitis B virus-related liver diseases

Braz. j. med. biol. res; 52 (10), 2019
Regucalcin is a soluble protein that is principally expressed in hepatocytes. Studies of regucalcin have mainly been conducted in animals due to a lack of commercially available kits. We aimed to develop an enzyme-linked immunosorbent assay (ELISA) to quantify serum regucalcin in patients with hepatitis ...

HBV epidemiology and genetic diversity in an area of high prevalence of hepatitis B in southern Brazil

Braz. j. infect. dis; 22 (4), 2018
ABSTRACT Background Hepatitis B virus (HBV) infection is a major public health problem in Brazil. HBV endemicity is usually moderate to low according to geographic regions, and high prevalence of this virus has been reported in people of some specific Brazilian counties, including those with a strong in...

Identification of hepatitis B virus A1762T/G1764A double mutant strain in patients in Southern Brazil

Braz. j. infect. dis; 21 (5), 2017
Abstract Infection by hepatitis B virus (HBV) is a worldwide public health problem. Chronic HBV infection with high viral replication may lead to cirrhosis and/or hepatocellular carcinoma. Mutant HBV strains, such as the HBV A1762T/G1764A double mutant, have been associated with poor prognosis and higher...

Basal core promoter and precore mutations among hepatitis B virus circulating in Brazil and its association with severe forms of hepatic diseases

Mem. Inst. Oswaldo Cruz; 112 (9), 2017
BACKGROUND In Brazil, few studies have investigated the prevalence of infection with the precore (PC) and basal core promoter (BCP) mutants of the hepatitis B virus (HBV). OBJECTIVES This study aimed to analyse the frequency of PC and BCP mutations among patients infected with HBV and to evaluate the ...

Distribution of HBV subgenotypes in Ribeirão Preto, Southeastern Brazil: a region with history of intense Italian immigration

Braz. j. infect. dis; 21 (4), 2017
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 pre...

Influence of Treg cells and HBV genotype on sustained response and drug resistance in the treatment with nucleoside drugs

Braz. j. med. biol. res; 50 (3), 2017
We aimed to investigate the influence of regulatory T cells including CD4+CD25+, CD8+CD28- and hepatitis B virus (HBV) genotype on sustained virological response and tolerance of nucleoside drugs. One hundred and thirty-seven patients were enrolled. Lamivudine was administered to 84 patients. Entecavir w...

Prevalence of mutations in HBV DNA polymerase gene associated with nucleos(t)ide resistance in treatment-naive patients with Chronic Hepatitis B in Central China

Braz. j. infect. dis; 20 (2), 2016
Abstract Objective There are a lot of disagreements in the studies on hepatitis B virus (HBV) DNA polymerase mutation rate associated with nucleos(t)ide analogues (NAs) in treatment-naive chronic hepatitis B (CHB) patients. This is the first study aimed to investigate the prevalence of spontaneous HBV r...
