title: [Permeability of dialysis membranes for hepatitis-B virus: on the prophylaxis of hepatitis in a haemodialysis centre (author's transl)].
abstract: Dialysis fluids of two hepatitis-Bs (HBs) antigen-positive dialysis patients were tested for hepatitis-B virus. Total dialysate volume of 5.5 litres each - as obtained on haemodialysis with the Redy-recirculation system - was concentrated by ultrafiltration and trap and rate-zonal ultracentrifugation, followed by fractionation, and purified. Electron-microscopic evidence of permeability of an intact dialysis membrane for hepatitis-B was obtained. Concentration of hepatitis-B virus was at least 10(3) to 10(4) particles per total volume. Because of the potential infectiousness of the dialysis apparatus by effective heat sterilisation after every dialysis is essential.
