title: Persistent generalized lymphadenopathy in Northeastern Italy: increased frequency of HLA-DR 5.
abstract: We undertake a study of Italian intravenous drug abusers and male homosexuals with the prolonged generalized lymphadenopathy syndrome (PGL). 75% of the subjects had the HLA-DR 5 antigen (relative risk 3.25). Only one patient was DR 2 positive. 14/20 subjects had anti-HTLV III antibodies and immunological malities were a rather constant finding.
