The rate of progression to new AIDS defining events has
been reduced considerably since the introduction of potent
antiretroviral combination therapy.
1 2
It is unclear,
however, whether the reduction has been the same for all opportunistic
infections and malignancies, or whether the effect has been greater for
some conditions than for others. We examined this question in the Swiss HIV Cohort Study, a large community cohort of adults with HIV infection.

The study methods are described in detail elsewhere. 1 3 The cohort includes the majority of people with advanced HIV infection in Switzerland. Potent antiretroviral combination therapy (triple combinations including at least one protease inhibitor) was gradually introduced from 1995 onwards. By mid-1997, 70% of patients with a history of CD4 cell counts below 200 × 106/l were receiving this treatment.
The incidence of all new AIDS conditions fell from 157 events
(95% confidence interval 148 to 166) per 1000 person-years in 1992 to
1994 (before combination therapy) to
