In this cross-sectional study, 207 hepatitis B surface antigen (HBsAg)-negative kidney transplant recipients were evaluated based on demographic and epidemiological data and on the levels of serological markers of hepatitis B virus (HBV) and hepatitis C virus infection and liver enzymes. Patients with HBV or human immunodeficiency virus infection were excluded. Sera were analysed for the presen...

OBJECTIVES We investigated the prevalence of hepatitis B virus (HBV) markers and occult HBV infection in a general adult population in Korea. METHODS HBsAg, anti-HBs and anti-HBc were analyzed on 1,091 samples of routine medical check-up examinees by chemiluminescence immunoassay. Nucleic acid amplification test (NAT) was performed on 1,047 HBsAg-negative samples by multiplex real-time polyme...

In this issue of the Iranian journal of Kidney Diseases, the case report of “Successful Pregnancy in a Kidney Transplant Recipient With Chronic Hepatitis B Virus Infection” by Kashif and colleagues1 confronts us to different challenging topics in nephrology. First, hepatitis B virus (HBV) infection has been discovered after kidney transplantation with a negative report of hepatitis B surface an...

objective: occult hepatitis b infection is a form of hepatitis in which despite of absence of detectable hbsag, hbv-dna is present in peripheral blood of patients. this clinical form of b hepatitis creates some problems for the iranian blood transfusion services. therefore, the aim of this study was the evaluation of status of occult hepatitis b infection in the rafsanjanese blood donors. mate...

Occult hepatitis B virus (HBV) infection is defined as persistence of HBV DNA in liver tissues, with or without detectability of HBV DNA in the serum, in individuals with negative serum HBV surface antigen (HBsAg). Despite accumulating evidence suggesting its important clinical roles, the molecular and virological basis of occult hepatitis B remains unclear. In an attempt to establish new hepat...

BACKGROUND Occult hepatitis B virus (HBV) infection (OBI) is characterized by HBV DNA persistence even though the pattern of serological markers indicates an otherwise resolved HBV infection. Although OBI is usually clinically silent, immunocompromised patients may experience reactivation of the liver disease. CASE PRESENTATION We report the case of an individual with human immunodeficiency v...
