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...

Hepatitis B virus (HBV) recurrence after liver transplantation for HBV-associated liver diseases results in decreased patient and graft survival. Herein we have reported two cases of HBV recurrence following relapse of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT). Both cases had LDLT for end-stage liver disease secondary to HBV infection with nodules of HCC exc...

Introduction: Hepatitis B and C are major health problems in many countries, especially developing areas. The frequency of hepatitis B is less than 0.8%, and chronic hepatitis C is less than 0.5% in the general population of Yazd in the center of Iran. Large vehicle drivers have some risk factors for acquiring hepatitis B and C infection. This is important because viral hepatitis complications,...

Primary biliary cirrhosis (PBC) is a slowly progressive cholestatic autoimmune liver disease characterized by progressive bile duct injury. The most common symptoms of this disease include fatigue and pruritus. The diagnosis of PBC is based on cholestatic biochemical liver tests, presence of antimitochondrial antibodies, and characteristic histological biopsy findings. We report a case of a pat...

Immunosuppressive drugs are the milestone of treatment of autoimmune diseases, but they can lead to serious complications, including hepatitis B virus reactivation in HBV carriers as well as in patients with occult HBV infection (OBI). A 36-year-old man with OBI was diagnosed with pemphigus vulgaris. He was prescribed prednisolone and his hepatitis B surface antigen turned positive. Viral repli...

BACKGROUND Previous studies have documented a high prevalence of hepatitis E among patients undergoing maintenance hemodialysis. Available studies reporting on the seroprevalence of hepatitis E in hemodialysis patients in Iran, an endemic region for the disease, are sparse. OBJECTIVES The present study aimed to determine the prevalence rate of anti-hepatitis E antibody in hemodialysis patient...

conclusions hbv vaccination in infancy is effective at preventing chronic hbv infection but is less effective at preventing occult hbv infection. similar studies examining the efficacy of adult hbv vaccination in preventing occult hbv have not been performed. this case highlights the importance of carefully determining the hbv status of high-risk individuals, as vaccination history and the pres...

Hepatitis B often progresses to decompensated liver cirrhosis requiring orthotopic liver transplantation (OLT). Although newer nucleos(t)ide analogues result in >90% viral and hepatitis activity control, severely decompensated patients still need OLT because of drug-resistant virus, acute exacerbation, or hepatocellular carcinoma. Acute hepatitis B is also an indication for OLT, because it can ...
