 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

background and aims: end-stage renal disease patients treated by hemodialysis (hd) are more susceptible for infection by viral hepatitis and human immunodeficiency virus (hiv) infections. infection by these viruses is promoted by the characteristic immunological dysfunction that develops in renal failure and interferes with the patient's ability to eliminate these viruses. prevalence of th...

Background & Aims: Hepatitis B infection is a global health problem. Hepatitis B virus can escape from the innate immune system, however adaptive immune system mainly acts against it. Transforming growth factor (TGF-) has three isoforms in mammals. Several studies have recently shown that TGF-1 suppresses replication of hepatitis B virus. Moreover, high expression of this factor is effective in...
