Unique Identifier : AIDSLINE ICA10/94369589 AB OBJECTIVE: To identify temporal trends of AIDS associated Kaposi's sarcoma (KS) in Spain. METHODS: Data from 18.256 AIDS cases reported to the Spanish AIDS Registry from 1981 to 1992 and data from a retrospective cohort of AIDS patients from three different Autonomous Communities (Madrid, Baleares and Catalonia) were used. Follow-up data included both clinical outcome and death. A total of 3.945 AIDS patients followed for 6.296 person years were included in the cohort. RESULTS: Starting in 1985 and for each subsequent year the KS presenting percentage was as follows: 14.4, 11.04, 9.28, 6.4, 6.2, 6.0, 6.3 and 6.2 in 1992. No significant trends were identified after the introduction of the 1987 CDC AIDS definition criteria (p = 0.43, 0.35 and 0.29 for all cases, IVDUs and homosexual men respectively). Annual incidence rates by cohort of diagnosis showed a slight but non significant decrease in the first year, but a slight and non significant increase in the second year after AIDS diagnosis. DISCUSSION: In our setting, although KS has not decreased as an AIDS presenting form, it tends to increase as a subsequent AIDS diagnosis. Natural history of HIV have changed, and the assessment of KS trends over time should take in account follow-up data and specific local features like the prevalence of other opportunistic infections, as tuberculosis.
