Three hundred and two intravenous drug addicts (IVDA) from five towns in Northeastern Italy were studied. Of the males, 37/249 (14.8%) were homosexuals and of the females, 29/53 (54.7%) were prostitutes; 118 (39.0%) were alcoholics. AST levels were abnormal in 31.8%, ALT in 45.7%, GTP in 36.4%, and bilirubin in 14.6%. The prevalence of HBsAg (13.9%) and HBeAg (21.4% of HBsAg positive) was significantly higher than in 2,983 controls (4.2% and 6.3%, p less than .001 and p less than .02, respectively). Of the HBsAg positive subjects, 51.7% had anti-HDV antibodies. Among 260 HBsAg negative cases, 146 (56.2%) were anti-HBs and anti-HBc positive, 76 (29.2%) were anti-HBc positive and anti-HBs negative (25 anti-HBe positive and 51 anti-HBe negative), and 38 had no HBV markers. Anti-HIV ELISA positive subjects came to 70.5% (triplicate determination with absolute concordance) and Western blot analysis confirmed the results in 99.1% of ELISA positive and 100% of ELISA negative subjects. The prevalence of anti-HIV was significantly higher in anti-HBc positive than negative cases (p less than .02), even excluding HBsAg positive subjects. Cases negative for HIV and HBV had a significantly lower median duration of drug abuse than those with past or present infection (36 vs 60 months, p less than .001). HIV-related diseases were present in 56.3% of the cases (120/213; PGL in 94, ARC in 24, and AIDS in two).(ABSTRACT TRUNCATED AT 250 WORDS)

HBV, HDV and HIV infections in 242 drug addicts: Two-year follow-up

et al. 1988

View full text Add to dashboard Cite

Of 242 north Italian heroin addicts, 24 (9.9%) were HBsAg positive. HBeAg was positive in two of them (8.3%), anti-HBe in 16 (66.6%) and anti-HDV in 21 (87.5%). Of the 218 HBsAg negative, 182 (83.5%) had anti-HBc, 72 (33.0%) anti-HBe and 97 (44.5%) anti-HBs. One-hundred-eighty-five drug addicts were anti-HIV positive (76.4%); 77 of these (41.6%) were asymptomatic, 93 (50.3%) had PGL and 15 (8.1%) ARC. T4+ cell count was significantly lower in subjects with ARC as was T4+/T8+ ratio in subjects with PGL and ARC. During a median follow-up of 9.5 months (range 4-25), we observed three new cases of hepatitis (two caused by NANBV and one by HBV with HDV coinfection) and one new HIV infection. Ten anti-HIV positive subjects developed PGL and one AIDS.
