Unique Identifier : AIDSLINE ICA10/94370469 AB OBJECTIVE: To describe the changing spectrum of AIDS index diseases in Canada from 1981 to 1991. METHODS: The present analysis was based on the AIDS index diseases reported to the Bureau of HIV/AIDS Epidemiology as of March 1993. Analysis was restricted to persons aged 15-64 years who were diagnosed prior to December 31, 1991. The annual number of AIDS cases were adjusted for reporting delay; disease-specific incidence rates were calculated by standardizing rates to the 1991 Canadian population. Linear regressions were performed to test the changes in annual incidence rates for each index disease. Reported p-values are two-sided. RESULTS: A total of 6,641 adult AIDS cases were examined: 6,304 (94.9%) males, 337 (5.1%) females. As seen in the figure, the incidence of PCP peaked in 1989 with a rate of 3.18 per 100,000, declining to 2.74 per 100,000 in 1991 (p = 0.894). Similarly the rate of KS stabilized during this interval from 1.06 per 100,000 in 1987 to 1.14 per 100,000 in 1991 (p = 0.189). In contrast, the rates of all other AIDS defining illnesses increased from 1.48 per 100,000 in 1987 to 3.43 per 100,000 in 1991 (p = 0.001). Significant rate increases were observed for esophageal candidiasis, cytomegalovirus diseases, wasting syndrome, toxoplasmosis, and Mycobacterium avium complex disease. Changes in incidence over this period were especially marked for esophageal candidiasis where rates increased from 0.11 to 1.27 per 100,000 (p < 0.001), and for CMV where rates increased from 0.01 to 0.40 per 100,000 (p = 0.002). CONCLUSIONS: These findings highlight the importance of developing specific strategies to deal with emerging AIDS-associated diseases. Our data provide a cautionary note to practicing clinicians with regard to the relative widening of the spectrum of HIV index diseases. TABULAR DATA, SEE ABSTRACT VOLUME.
