CHARACTERISTICS AND PREVALENCE OF OCCULT HEPATITIS B VIRUS INFECTION IN PATIENTS WITH HEPATITIS C IN IRAN
ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...
متن کاملOccult hepatitis B virus infection: clearance or disguise?
Occult hepatitis B virus (HBV) infection is defined as presence of HBV DNA in the liver regardless of serum HBV DNA detectability in HBsAg-negative patients. Occult HBV infection is not uncommon in Korea because the prevalence of occult HBV infection depends on the HBsAg carrier rate. The underlying mechanisms for occult HBV infection is not fully understood yet, but both viral and host factors...
متن کاملUpdate on occult hepatitis B virus infection
The event of mutations in the surface antigen gene of hepatitis B virus (HBV) results in undetectable hepatitis B surface antigen with positive/negative anti-hepatitis B core (anti-HBc) antibody status in serum and this phenomenon is named occult hepatitis B infection (OBI). The presence of anti-HBc antibody in serum is an important key for OBI tracking, although about 20% of OBI cases are nega...
متن کاملOccult Hepatitis B Virus Infection in Chronic Hemodialysis Patients in Panje-Azar Hospital, Gorgan
Abstract Background and objectives: Hepatitis B virus infection is a major health problem in worldwide. The prevalence of Occult and chronic HBV in hemodialysis patients is higher than standard in developing countries. People with occult HBV are negative for HBV surface antigen (HBsAg) but positive for HBV-DNA. We aimed to evaluate occult hepatitis B infection in patients under hemodialysis in ...
متن کاملRole of hepatitis B virus genotype D & its mutants in occult hepatitis B infection
BACKGROUND & OBJECTIVES Non-detection of hepatitis B virus (HBV) envelope protein (hepatitis B surface antigen, HBsAg) in a chronically HBV infected individual has been described as occult infection. One possible reason for this phenotype is alteration in large (L-HBsAg) to small (S-HBsAg) envelope protein ratio associated with reduced or non secretion of HBsAg. This results in quantitative lev...
