Hepatitis B Reactivation in HBsAg Negative Renal Transplant Patients with Evidence of Previous HBV Infection: A Not Neglectable Occurrence

Prevalence of Occult Hepatitis B Infection among HBsAg Negative Blood Donors in Golestan Province

Background and Aims: Occult hepatitis B virus infection (OBI) is known as an important source of hepatitis B virus (HBV) infection. It is categorized as Hepatitis B surface antigen (HBsAg) not being present and low DNA viral load in serum. In this study, an attempt was made to investigate the outbreak of anti-HBc and OBI among the HBsAg-negative donors in Golestan province. Materials and Metho...

Reactivation of Hepatitis B Virus in HBsAg-Negative Patients with Hepatocellular Carcinoma

BACKGROUND & AIMS Despite increasing attention to hepatitis B virus (HBV) reactivation in hematologic settings, information on reactivation in hepatitis B surface (HBsAg)-negative patients with hepatocellular carcinoma (HCC) remains unknown. This study aimed to determine the incidence and risk factors of HBV reactivation in HBsAg-negative patients undergoing transarterial chemoembolization (TAC...

Detection of HBV DNA in Cerumen and Sera of Hbsag Negative Patients with Chronic Hepatitis B Infection

Dear Editor, Chronic carriers of hepatitis infection are living throughout the world mostly in the South East of Asia. Recent studies have shown that some HBsAg negative individuals may develop some sort of chronic hepatitis B which is detectable employing some new laboratory diagnosis techniques such as molecular tests. In human during decades, HBV had many mutations by which this virus has be...

Hepatitis B virus genotype, HBsAg mutations and co-infection with HCV in occult HBV infection.

BACKGROUND The association between mutations in the hepatitis B surface antigen (HBsAg) gene and the occurrence of occult HBV (OBI) in patients has not been studied adequately to determine if the two are correlated. The current study was aimed to investigate HBsAg mutations, the genotype of HBV and co-infection with HCV in OBI in the central part of Iran to determine any possible associations. ...
