[Hepatitis B and non-B in our case reports of post-transfusional hepatitis]

The Authors examined 52 patients with post-transfusional hepatitis admitted in the Insitute of Infectious Diseases in Perugia, from 1971 to 1977. 30 (57.7%) patients had "B" hepatitis, 22 (42.3%) "non B" hepatitis. The incidence of anti-HBs antibodies in the two groups of patients suggests that they are partially protective against "B" hepatitis. "B" and "non B" hepatitis resulted clinically different only in the incubation period, 95.6 days (mean) for "B" hepatitis and 62.1 days (mean) for the "non B" hepatitis.
