title: [The epidemiology and acquired immunodeficiency syndrome--status and trends].
abstract: Up to June 1991 a total of 6,604 AIDS cases were reported to the central AIDS-registry at the Federal Health Office. As typical for "pattern I" countries most of the AIDS-cases are homo/bisexual men (70%), followed by i.v. drug users (IDU, 13%). However, the proportion of homo/bisexual men is constantly decreasing since 1986 while the proportion of IDU's is increasing. As also observed in other industrialized countries a flattening off in the AIDS incidence curve is seen since 1989. Probable reasons for this observation are a decrease of new infections since 1984/85 (due to early saturation of the populations at highest risk and to the early onset of prevention campaigns in these populations) and improved therapeutic strategies in the prevention of AIDS indicating diseases. However, since about 60,000 people are estimated to be HIV infected in the FRG today AIDS incidence will remain on a stable level for the next years regardless the number of new infections occurring today. Since 1988 major changes in the distribution of AIDS indicating diseases are seen. While Kaposi's sarcoma is constantly decreasing non Hodgkin lymphomas, HIV encephalopathy and wasting syndrome are increasing. Due to the effective primary prophylaxis of pneumocystis carinii pneumonia (PCP) by pentamidine the proportion of PCP as AIDS-indicating opportunistic infection decreased from more than 60% in 1988 to 41% in 1991. The second most frequent opportunistic infection is now toxoplasmosis (19%). The changes in the distribution of AIDS-indicating diseases and the increasing proportion of IDU's have major implications on patient care as well as diagnostic and therapeutic procedures.
