Clinical and demographic features of HIV infection in El Salvador

Abstract

Objective. To understand some of the clinical and demographic features of the epidemic of infection by HIV in El Salvador prior to the availability of antiretroviral therapy in that country. Methods. We conducted a retrospective review of HIV-infected individuals who were admitted to Hospital Rosales, which is a large public teaching hospital in San Salvador, El Salvador, during the 5-year period of 1994 through 1998. Chart abstraction was done of 194 out of the 208 individuals admitted to the Infectious Diseases Unit at Hospital Rosales (14 charts could not be located). We also carried out a sampling of other HIV-infected adults treated in other parts of the hospital. Results. Of the 250 patients whose records we reviewed, 67% were men and 86% were from an urban area. The mean age at HIV diagnosis was 34 years. In terms of occupation, 50% of the men were day laborers; 76% of the women were housewives, and 8% of the women were commercial sex workers. All the women studied listed only heterosexual contact as their risk behavior. Of the men, 9% of them said they had sex only with men, 17% said with both men and women, and 65% said with female commercial sex workers. In terms of drug use, 2% of the patients reported they had used injection drugs at some point. At their initial medical visit to Hospital Rosales, over half of the 250 patients presented with a respiratory complaint or with diarrhea, 6% had pulmonary tuberculosis (TB), and 5% had extrapulmonary TB. Of the 250 patients, 177 of them (71%) had AIDS at the first medical visit. Of the 250, 138 of them (55%) were lost to follow-up. Of the remaining 112 persons, 81 of them (72%) were known to have died. Of those 81, 38 of them (47%) died of unknown causes and 21 (26%) died of TB. Conclusions. The HIV-infected adults treated at the Hospital Rosales during the 1994-1998 period were usually infected through heterosexual sex, were symptomatic at the time of presentation, and were often lost to follow-up. Utilizing the results of our study and of other research, efforts to expand early intervention, counseling and testing, and targeted prevention activities should be strengthened.
