A comparison of the progression rate to acquired immunodeficiency syndrome between intravenous drug users and homosexual men.

In order to study differences in progression to Acquired Immunodeficiency Syndrome (AIDS) between risk groups, 205 homosexual men and 185 intravenous drug users (IVDUs) were followed from diagnosed seropositivity for Human Immunodeficiency Virus Type-1 (HIV) for a mean period of 46 months (range 1-88 months). Seven (4%) IVDUs and 55 homosexual men (27%) were diagnosed with AIDS during the follow-up period. The probability of being AIDS-free four years after diagnosed HIV positivity was 0.

Slow progression to AIDS in intravenous drug users infected with HIV in Norway.

Study Objective: To study the rate of progression to AIDS and to death, and the causes of death among intravenous drug users in Norway.

Design: This was a prospective study. The study population was followed from diagnosis of HIV seropositivity until death or the end of the study period.

[Mortality and causes of death among intravenous drug addicts in Oslo].

In order to study mortality and causes of death among intravenous drug users in Oslo, 1,009 (829 HIV negative and 180 HIV positive) intravenous drug users were followed from their first HIV test for a mean period of 36 months (range 1-67 months). 87 (55 HIV negatives and 32 HIV positives) died during the follow-up period. Compared with the general population with the same age and sex distribution, the relative risk of death for the intravenous drug users was 31.

Differences in mortality rates and causes of death between HIV positive and HIV negative intravenous drug users.

In order to study differences in mortality and causes of death between HIV positive and HIV negative intravenous drug users (IVDU), 1009 (180 HIV positive and 829 HIV negative) IVDU in Oslo, Norway, were followed from their first HIV test for a mean period of 36 months (range 1-67 months). Eighty-seven (55 HIV negatives and 32 HIV positives) died during the follow-up period. The risk of death for IVDU was 31 times higher than for the general population.

Hepatitis B antibodies in HIV-infected homosexual men are associated with more rapid progression to AIDS.

Objective: To study the influence of previous or present hepatitis B virus (HBV) infection on HIV disease progression.

Design: A prospective study of HIV-positive individuals from HIV diagnosis to diagnosis of AIDS or to the end of the follow-up period on 1 January 1991. Mean follow-up time was 62 months.
