Introduction: Acute hepatitis has several causes. Transfusion of non-infected blood to the virus and avoidance of undesirable social contacts have reduced the prevalence of hepatitis B and C transmission. Improved socioeconomic status and access to healthy food and water have also reduced the prevalence of hepatitis E and A. The transition from Hyper Endimicity to Intermediate or Low Endimicity...

Abstract Background: Mannose-binding lectin (MBL) is a constituent of the human innate immune system which may play an important role in combating a variety of infectious diseases and thus may be important for determining hepatitis B virus (HBV) persistence. In this study, we determined MBL genotypes in chronic hepatitis B subjects, spontaneously recovered subjects and healthy controls. Me...
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 these v...
background: sen virus (senv) is the latest virus proposed as a cause of unknown hepatitis cases. among nine detected genotypes of the virus, genotypes d and h are more frequent in hepatitis cases of unknown origin. the aim of this study was to determine the frequency of senv-d and senv-h genotypes in the sera of healthy individuals and hepatitis b and c patients. methods: totally, 200 serum sam...
