Survival of AIDS patients according to type of AIDS-defining event. The AIDS in Europe Study Group
Abstract
There are known to be wide differences in the prognosis of patients with a diagnosis of AIDS. In this study of 6578 patients with AIDS form 17 European centres, we develop a ranking of AIDS-defining illnesses, and determine how well this ranking holds after adjustment for potential confounding variables. Survival from each AIDS-defining event was calculated and ranked using Kaplan-Meier estimation of median survival. Cox proportional hazards models with each disease modelled as a time dependant covariate were used to determine the risk of death after each diagnosis, before and after adjustment for potential confounders. Median survival after an initial AIDS-defining diagnosis of progressive multifocal leukoencephalopathy and malignant lymphoma was particularly poor (2 and 5 months respectively), while the longest median survival occurred after initial AIDS-defining illnesses of Kaposi's sarcoma and extrapulmonary tuberculosis (17 and 22 months respectively) Patients diagnosed with a primary brain lymphoma had shorter median survival times than patients with a peripheral lymphoma (median survival of 1 month and 4 months respectively P < 0.0001). In general, median survival in patients with cutaneous Kaposi's sarcoma (skin, oral)...Continue Reading
