PORPHYRIA-CUTANEA-TARDA ASSOCIATED WITH HUMAN-IMMUNODEFICIENCY-VIRUS INFECTION

Since 1987, about 60 cases of porphyria cutanea tarda (PCT) associated with human immunodeficiency virus (HIV) have been reported. The respe ctive roles of HIV and toxic hepatic factor in PCT remain unclear. We report 10 new cases and analyse the following toxic hepatic factors: h epatitis C and B, alcoholism, drugs. The route of HIV transmission to these 10 men were: IV drugs abuse (3), home/bisexuality (4), heterosex uality (1), and unknown (2). When PCT was diagnosed, their average age was 38 years (29-54) and the HIV-infection had been established for 4 .8 years (0.33-9). Seven men had HIV-related symptoms and a CD4(+) lym phocyte count below 200/mm(3). Cutaneous signs and urinary porphyrin c ount were characteristic. Alcohol abuse was present in 8/10 patients. AST, ALT and/or gamma GT were high in 9/10 patients; 5/10 patients had HCV antibodies (4 were HCV-PCR positive). HBs antigenemia was negativ e among the 5/8 patients with HBV antibodies; 10/10 patients took pres cribed hepatotoxic drugs. Our series confirms the presence of toxic he patic factors in PCT of HIV-positive patients. Hepatitis C, alcoholism and hepatotoxic drug consumption seem to be triggers for the appearan ce of PCT in HIV-positive patients.
