Widespread HIV counseling and testing linked to a community-based tuberculosis control program in a high-risk population

The aim of the work reported here was to evaluate community-wide screening for HIV infection that was linked to a tuberculosis control program in a population at high risk for both infections. Between May 1990 and August 1992, adults in Cité Soleil, Haiti, were recruited by community health workers at their homes and in clinics for individual, clinic-based counseling and testing for HIV and tuberculosis. All of the screened subjects were offered post-test HIV counseling. Those with active tuberculosis received treatment, while those with latent tuberculosis and HIV infection were offered an opportunity to participate in a trial of antituberculosis chemoprophylaxis. The 10 611 individuals screened for HIV represented 10.0 percent of the adult population in Cité Soleil. HIV infection was detected in 1 629 (15.4 percent) and active tuberculosis in 242 (2.3 percent). Latent M. tuberculosis infection was found in 4 800 (67.5 percent) of 7 309 community residents who completed tuberculosis screening, 781 (16.3 percent) of whom were coinfected with HIV. The high prevalence of HIV infection found in this screened population, as compared to other groups undergoing HIV screening in the same community, suggests that people at high risk for HIV infection selectively sought or accepted tuberculosis clinic screening. Also, many people with active tuberculosis were identified earlier in the course of their disease than they would have been in the absence of a screening program. Overall, the results indicate that community-based screening for HIV infection within a tuberculosis control program can result in effective targeting of screening for both infections

Servicio de orientacion y deteccion de VIH vinculado a un programa comunitario antituberculoso en una poblacion de alto riesgo / Wide-spread HIV counseling and testing linked to a community based tuberculosis control program in a high-risk population

La finalidad del trabajo que aqui se describe fue evaluarel tamizaje comunitario para la deteccion de los casos de infeccion por VIH vinculado a un programa de lucha anticuberculosa en una poblacion de alto riesgo de ambas infecciones. De mayo de 1990 a agosto de 1992, trabajadores de salud comunitarios se comunicaron con adultos en domicilios y dispensarios de Cite Soleil, Haiti, para ofrecerles servicios institucionales de asesoramiento individual y de deteccion de VIH y de tuberculosis. A todas las personas que aceptaron la prueba se les dio asesoramiento posterior sobre VIH. Las que tenian tuberculosis activa recibieron tratamiento y a las que tenian enfermedad latente mas infeccion por VIH se les dio la oportunidad de participar en un ensayo clinico sobre quimioprofilaxis antituberculosa. La elevada prevalencia de infeccion por VIH en la poblacion examinada, al compararsela con otros grupos sometidos a tamizaje en la misma comunidad, indica que las personas en alto riesgo de infeccion por VIH buscaron selectivamente o aceptaron someterse a las pruebas de tamizaje ofrecidas en los dispensarios de tuberculosis. Asimismo, a muchas personas se les diagnostico tuberculosis activa en una fase mas temprana de la enfermedad de lo que hubiera sido posible sin un programa de tamizaje. En general, los resultados indican que cuando el tamizaje comunitario para la deteccion de VIH es parte de un programa de lucha antituberculosa, el resultado puede ser una mejor focalizacion de destinatarios para las pruebas de deteccion de ambas infecciones
