Abstract

MENESIA, Elisa Ortuzar et al. Survival of AIDS patients in a city in southeastern Brazil. Rev Panam Salud Publica [online]. 2001, vol.10, n.1, pp. 29-36. ISSN 1020-4989.  http://dx.doi.org/10.1590/S1020-49892001000700005.

Objective. To assess survival in patients diagnosed with AIDS in the city of Ribeirão Preto, Brazil, between 1986 and 1997. Methods. The epidemiological records of 2 214 patients diagnosed during the study period were retrospectively reviewed. From those, 1 231 patients with at least 30 days of follow-up after the date of diagnosis were included in the study. Information concerning deaths was obtained from hospitals and vital-records offices. Results. Survival for the group as a whole was 310 days (10.3 months) over the period of 1986 through 1997. Median survival was 362 days for 1986 to 1990, 260 days for 1991 to 1995, and 864 days for 1996 and 1997. The Kaplan-Meier survival curves and the log-rank test showed significant differences for the following variables: sex, age, period when diagnosis was made, and presence of candidiasis and of cerebral toxoplasmosis. Cox's regression showed an association between reduction of survival and the following variables: age (in comparison to individuals younger than 15 years, hazard ratio = 1.435 for age between 15 and 34 years, and 1.681 for age above 35 years); period of diagnosis (in comparison to the period of 1996 and 1997, hazard ratio = 1.682 for the period from 1986 to 1990, and 2.324 for the period from 1991 to 1995); and presence of candidiasis (hazard ratio = 1.391). The hazard ratio for the presence of cerebral toxoplasmosis was 1.063, with a probability value close to the limit of significance. Conclusions. Our results show a striking increase in survival in 1996 and 1997, coinciding with the availability and utilization of highly active antiretroviral drugs.
