HIV infection in intravenous drug abusers in Berlin: risk factors and time trends.
To investigate the epidemiology of HIV infection among intravenous drug abusers (IVDA) in Berlin (West), from October 1984 to October 1988, 741 heterosexual IVDA were recruited from facilities for drug treatment and counseling. In this group 22.8% were seropositive for antibodies against HIV, representing 21.1% of the females and 23.5% of the males. Seroprevalences of hepatitis B, hepatitis A, and lues were 67.7%, 40.1%, and 4.0%, respectively. Seropositivity for HIV antibodies correlated with positive seromarkers for hepatitis B and A, and with certain behavioral and social features such as sharing of injection equipment, imprisonment, and intravenous drug use in prison. The crude time trend of HIV seroprevalence shows an increase from 17.1% in those subjects who discontinued i.v. drug abuse in 1983 or earlier to 31.5% in 1985, and a decrease over the past 3 years to 14.1% in 1988. After adjusting for temporary changes in the study group, the estimated HIV seroprevalence odds show an almost steady increase and were significantly higher for those who were injecting drugs in 1987 and 1988 compared with those who stopped i.v. drug use before 1984. Thus IVDA with a persistent risk profile are at a still-increasing risk of acquiring HIV infection.
