conclusions the mutation ratio difference between genotypes b and c in children was higher than that of adults and several combined mutations were exclusively detected in children with chronic hbv genotype c infection associated with higher viral load. objectives the aim of this study was to assess the mutation profiles of bcp and precore regions in different hbv genotypes in chronically infect...

conclusions this study showed that cccdna can be detected in the plasma specimen of 17.9% of iranian treatment-naive patients with chronic hepatitis b infection. therefore, designing prospective studies focusing on the detection of cccdna in these patients would provide more information. results the mean (sd) age of the patients was 41.1 ± 12.4 years (range, 20 - 62 years). from a total of 106 ...

abstract one of the best reliable markers of hepatitis b virus infection is antibodies to the core antigen (anti-hbc). a first-time blood donor with hbsag positivity was identified as an hbv carrier that was anti-hbc negative. the patient was followed for 24 months in order to investigate the evolution of his hbv serological profiles and hbvdna (pcr). in the follow-up for 24 months, hbsag, hbea...

Although the risk of acquisition of hepatitis B or hepatitis C virus through blood products has considerably reduced since the last decade, some infected patients are candidates to stem cell transplantation. Others may have no alternative than an infected donor. In all these cases, recipients of transplant are prone to short and long term liver complications. The evolution of liver tests under ...

BACKGROUND & AIMS Quantitative HBsAg has been recognized to assist in the management of chronic hepatitis B virus (HBV) infection. However, its role in disease monitoring of HBeAg-negative patients remains unclear. We aimed to investigate the longitudinal HBsAg change in HBeAg-negative carriers with HBV genotype B or C infection. METHODS This is a retrospective cohort study conducted in a uni...

BACKGROUND AND AIMS There is lack of a practical biomarker to predict sustained virological response (SVR) in chronic hepatitis B (CHB) patients undergoing peginterferon alfa-2a (PEG-IFN). The aim of this pilot study was to identify immunological features associated with SVR. METHODS Consecutive 74 CHB patients receiving 24 weeks (for hepatitis B e antigen (HBeAg)-positive) or 48 weeks (for H...

UNLABELLED The serum level of the human cathelicidin-LL37, an immunomodulatory vitamin D-induced peptide was less studied in viral hepatitis. The aim of this study was to analyse the cathelicidin-LL37 and vitamin D serum level in hepatitis B virus (HBV) and hepatitis C virus (HCV) infections and their correlations. METHODS A total of 52 patients with HBV and HCV hepatitis and 22 controls were...

BACKGROUND To investigate dynamic fluctuations of serum viral load and peripheral T-lymphocyte subpopulations of chronic hepatitis B patients and their correlation during entecavir therapy. METHODS Fifty-five patients received entecavir 0.5 mg/d therapy. Serum HBV DNA load was measured by Real-Time-PCR, and the levels of peripheral T-lymphocyte subpopulations by flow cytometry biweekly, every...

BACKGROUND Little is known about the risk of hepatitis B virus (HBV) reactivation in patients receiving interferon (IFN)-free direct-acting antiviral agents (DAAs) for hepatitis C virus (HCV). METHODS Patients who were seropositive for HBV core antibody and who received IFN-free DAAs for HCV were enrolled. Hepatitis B virus reactivation was defined as reappearance of serum HBV deoxyribonuclei...

Chronic hepatitis B virus (HBV) infection is associated with lower prevalence of hyperlipidemia (HLP). However, occult HBV infection (OBI) in HLP patients has not yet been explored. OBI is defined as the presence of detectable HBV DNA in serum or liver tissue but undetectable HBV surface antigen in serum. In this study, 1,036 HLP patients and 1,134 replacement blood donor controls were recruite...
