BACKGROUND The occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the sera or in the liver biopsy and the absence of hepatitis B surface antigen (HBsAg) by serological test. OBJECTIVES The current study aimed to evaluate the occult HBV infection by polymerase chain reaction (PCR) and determine HBV genotyping among the patients with abnormal alanine...
background occult hepatitis b virus infection (obi) is defined as the presence of hepatitis b virus (hbv) dna in the liver and/or in the serum of patients with negative results of hepatitis b s antigen (hbsag) test with or without serological markers of previous viral exposure. the impact of obi in patients with chronic hepatitis c (chc) is still unclear. objectives the aim of this study was to...

The hepatitis B virus (HBV) is one of the most frequently transmitted agents in dialysis units. Occult hepatitis B is characterized by HBV infection without detectable surface antigen (HBsAg) in the patient's serum, a positive or negative HBV DNA marker result in the serum and a positive result in the liver tissue, which leads to the potential risk of transmission during renal replacement thera...
Although occult hepatitis B virus (HBV) infections in individuals without detectable hepatitis B surface antigen (HBsAg) may occur and have been reported to be common in patients with chronic hepatitis C, the clinical relevance remains controversial. We searched for serum HBV DNA in 210 HBsAg-negative patients with hepatitis C virus (HCV)-related liver disease (110 patients with chronic hepatit...
In the recent issue of Middle East Journal of Digestive Diseases, we read with great interest the article by Bahari et al.1, “Significance of response to hepatitits B vaccine in subjects with isolated antibody to hepatitis B core antigen”. We wanted to specify some important matters related to the article. Initially, definition of occult hepatitis B virus infection is the existence of hepatitis...
