background and objective: presence of hepatitis b core antibody (anti-hbc) in the absence of hepatitis b surface antigen (hbsag) and hepatitis b surface antibody (anti-hbs) is defined, as isolated anti-hbc. little is known about the clinical significance of the isolated anti-hbc in hepatitis b virus (hbv) infections. the aim of this study was to assess the significance of anti-hbc as the only m...

Hepatitis B virus (HBV) is an etiological agent of hepatitis B infection. Hepatitis B is a life-threatening disease that affects the liver. The clinical outcomes of the disease are varied from asymptomatic disease to serious complication such as cirrhosis and hepatocellular carcinoma (HCC). Despite availability of the vaccine and appropriate treatment, hepatitis B infection still remains a majo...

OBJECTIVE The prevalence of hepatitis B and hepatitis C in a sexually transmitted disease (STD) clinic population was studied, along with the prevalence of various STD agents, in an attempt to identify possible STD markers for the hepatitis C virus and help delineate the role of hepatitis C as an STD. The hepatitis C antibody rates found in the STD clinic were also compared with those found amo...

BACKGROUND AND OBJECTIVES The relationship between hepatocyte expression of hepatitis B virus (HBV) antigens, liver histology and viral replication in asymptomatic subjects with incidental detection of hepatitis B surface antigen (HBsAg) remains unclear. We evaluated the histological activity index (HAI) and hepatocyte expression of viral antigens with replicative status in asymptomatic chronic...

Background and Aims: Recently, a novel DNA virus was isolated from the serum of a patient with post-transfusion non A-G hepatitis and named TT virus. The aim of this study was to determine the prevalence TT virus among cirrhotic patients due to hepatitis B & C in infection Ahwaz. Methods: The prevalence of TTV infection was studied in 41 patients with liver cirrhosis. TTV DNA was detected ...

OBJECTIVES Health care workers, including dentists, are at the front line for acquiring blood-borne virus infections. This study aimed to investigate the prevalence of hepatitis B, hepatitis C and human immunodeficiency viruses among Iranian dentists. MATERIAL AND METHODS The survey included 1628 dental health care workers who attended the 51st annual Congress of the Iranian Dental Associatio...

A 51-year-old man who was hepatitis B surface antigen (HBsAg)-negative and positive for anti-hepatitis B surface antigen (anti-HBs) and anti-hepatitis B core antigen (anti-HBc), during rituximab therapy for chronic Lymphocytic leukemia, developed reactivation of hepatitis B virus (HBV) infection with hepatitis that proceeded towards hepatic failure and death in spite of lamivudine therapy. HBsA...

background: different studies have demonstrated that a small proportion of healthy individuals receiving the hepatitis b (hb) vaccine do not produce protective levels of anti-hb antibody, a phenomenon which could be linked to certain human leukocyte an-tigen (hla) class-ii alleles or haplotypes. objectives: the present study was under-taken to determine the frequency of hla class-ii alleles in ...
