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...

AIM To evaluate the long-term effects of anti-tumor necrosis factor-alpha (TNF-α) therapy on patients with chronic hepatitis B and C infections. METHODS Rheumatoid arthritis, ankylosing spondylitis and Crohn's disease patients administered anti-TNF-α therapy for at least 36 months were retrospectively reviewed for hepatitis B or C serology, liver function tests, viral load, genotype and liver...

Introduction: Prison, as the most important place for the transmission of infectious diseases, has particular importance, and prison populations are at high risk for infectious diseases like Hepatitis B & C. This study aimed to determine the prevalence of Hepatitis B & C among male inmates in six prisons of different provinces in Iran in 2012. Methods: In...

background: recently, some new viruses have been identified for their association with hepatitis which torque teno mini virus being among them. the aim of this study was to determine the frequency of torque teno mini virus in healthy individuals and hepatitis b and c patients in isfahan, iran. materials and methods: one hundred serum samples of healthy individuals from isfahan blood transfusion...

Background. Viral hepatitis is still one of the important health problems all over world today. Hepatitis B a life-threatening liver infection that can cause chronic infections. It increases risk death from cirrhosis and hepatocellular carcinoma. One most factors in or acute age infection. The earlier virus encountered, greater chronicity disease. Prevention perinatal transmission disease great...

Repeated administration of an intravenous immunoglobulin containing antibody to hepatitis B e antigen (anti-HBe) and antibody to hepatitis B core antigen (anti-HBc) but free of antibody to hepatitis B surface antigen (anti-HBs) before and after the inoculation of 10(4.9) 50% chimpanzee infective doses of hepatitis B virus (HBV) markedly prolonged the incubation period of HBV in experimentally i...

Two hepatitis B core proteins bearing the immunodominant region of the hepatitis E virus (HEV) capsid protein, one at the C terminus of hepatitis B virus core antigen (HBcAg) and the other within the HBcAg immunodominant loop, were constructed. Both chimeric proteins exhibited HEV reactivity, but only the first construct retained HBcAg reactivity. The second construct was used to develop an ant...

conclusions being a barber alone is not a potential risk factor for hbv infection, while hcv infection is still an occupational health hazards for barbers. we suggest more extensive case-control studies with regard to rates of hepatitis b and c markers among barbers in other iranian cities to assess the incidence of hepatitis b and c infections among this population. background hepatitis b viru...

METHODS We included 29 neonates with clinical signs and symptoms suggesting congenital infections, along with their mothers. The control group comprised 29 healthy neonates and their mothers. Laboratory evaluations were performed for each sample for liver function profiles and virological studies f...
