PREVALENCE OF OCCULT HEPATITIS B INFECTION IN IRANIAN CANCER PATIENTS BEFORE CHEMOTHERAPY TREATMENT.

Background: Occult hepatitis B infection is characterized by negative hepatitis B surface antigen (HBsAg) and also detectable hepatitis B virus (HBV) -DNA, with or without hepatitis B core antibody (anti-HBc). HBV reactivation in individuals under immunosuppressive therapy is critical, occurring in occult HBV.

Objective: In this study, we aimed to determine the prevalence of occult HBV infection among hepatitis B surface antigen negative in cancer patients before receiving chemotherapy.

Effect of different doses of furazolidone with amoxicillin and omeprazole on eradication of Helicobacter pylori.

Background: Resistance to metronidazole is one of the most common reasons for Helicobacter pylori treatment failure with classic triple therapy. In contrast, the clarithromycin-based regimen is not cost-effective for developing countries. Furazolidone is a very good substitute for metronidazole and clarithromycin, but its many side-effects limit widespread use.
