Viral hepatitis A and B in hemodialysed patients

In 113 hemodialysed patients, 167 hospitalized patients, and 143 outpatients the frequency of HAV and HBV markers were studied by testing HBsAg, anti-HBs, anti-HBc, HBeAg, anti-HBe, and anti-HAV. The hemodialysis patients in a dialysis-center had significantly more often HBV markers (85.7%) than those maintained on home-dialysis (46.5%). 29.9% of the hospitalized patients and 32.1% of the outpatients had HBV markers. By the anti-HBc test up to 41% of additional HBV infections could be detected.--The prevalence of anti-HAV was very high in all groups. Significant differences between the hemodialysis patients and the control groups existed only in the age groups up to 39 years.--The frequencies of HAV and HBV markers were related to age, duration of dialysis treatment, transfusional frequency, and transaminases. The HBV appeared as the clinically important hepatitis agent in dialysis.
