The serological status for both hepatitis B, C and D viruses was analy
zed for 500 HIV seropositive patients and for 1037 of a control group.
The prevalence was 31.4% for anti HCV, 13.8% for HBs Ag and 69.0% for
one or more HBV markers in HIV positive patients and respectively 2.5
%, 2.7% and 13.1% in control group. The markers for hepatitis D were f
ounded among 21% of the HBs Ag carriers (patients and control group),
correlated with drug IV use. The prevalence of anti-HCV was 71.6% in s
ubjects who had blood-borne HIV infection and 1.5% in those with sexua
lly acquired infection. The prevalence in control group was 10.2% and
1.7% respectively according to the same risk factors. The prevalence o
f HBs Ag was higher among HIV positive patients with sexual risk (17.5
%) than with blood exposition (9.9%) and a variation in the same direc
tion is observed in control group (3% vs 1%). The relation between hep
atitis B and hepatitis C was negative.
