ABSTRACT

INTRODUCCIÓN: en los últimos años se ha incrementado el número de pacientes cubanos infectados con VIH con un rápido deterioro clínico e inmunológico. OBJETIVO: determinar posibles factores asociados a progresión rápida a sida. MÉTODOS: se realizó un estudio de tipo caso-control. Se estudiaron 26 pacientes con progresión rápida a sida, atendidos en el Instituto de Medicina Tropical "Pedro Kourí", entre septiembre de 2007 y agosto de 2008, y 2 grupos controles A y B de 20 pacientes cada uno. Se analizaron variables sociodemográficas, clínicas y de laboratorio. Se determinó por análisis logístico multivariado la asociación entre las variables de exposición y la progresión rápida a sida. RESULTADOS: las variables asociadas con progresión rápida a sida por el estimado puntual del OR ³ 2 fueron: sexo femenino (OR: 17,0), no uso de condón (OR: 3,24), valor de linfocitos TCD4+ al momento del diagnóstico de VIH£ 25 por ciento (OR: 8,0) y £ 400 células/mm³ (OR: 3,27), candidiasis oral (OR: 66,20), y una carga viral > 10 000 UI/mL al momento del diagnóstico de VIH (OR: 4,62). La edad mayor de 30 años al diagnóstico de VIH, los hábitos tóxicos, el síndrome de retrovirosis aguda sintomático y el resto de las coinfecciones no se asociaron con progresión rápida a sida. CONCLUSIONES: además de factores virales e inmunológicos, existen otros de carácter clínico y epidemiológico asociados con progresión rápida a sida, que deben tenerse en cuenta en la evaluación inicial del paciente como son sexo femenino, no uso de condón, candidiasis oral, valor de linfocitos T CD4+ y carga viral al diagnóstico.


INTRODUCTION: in the last few years, the number of HIV Cuban patients expressing rapid clinical and immunologic deterioration has increased. OBJECTIVE: to find out the possible factors associated to rapid progression to AIDS. METHODS: a case-control study was carried out with the objective of determining possible factors associated with rapid progression to AIDS. Twenty six patients with rapid progression to AIDS, who were seen at "Pedro Kourí" Institute of Tropical Medicine from September 2007 to August 2008 together with two 20- patient control groups (A and B) were involved in the study. Social, demographic, clinical and laboratory variables were analyzed. By means of multivariate logistic analysis, the association between the exposure variables and the rapid progression to AIDS was determined. RESULTS: the variables associated with rapid progression to AIDS using the punctual estimate of the Odds ratio (OR³ 2) were: female (OR: 17.0), non-use of condom (OR: 3.24), percentage of TCD4+ lymphocytes at the moment of HIV diagnosis £25 percent (OR: 8.0) and the absolute count £ 400 cel/mm3 (OR: 3.27), oral candidiasis (OR: 66.20), and an HIV viral load >10 000 UI/ml at the moment of the diagnosis (OR: 4.62). The age older than 30 years at HIV diagnosis, the toxic habits, the symptomatic syndrome of acute retrovirosis and the rest of the co-infections were not associated with rapid progression to AIDS. CONCLUSIONS: besides those well-known viral and immunologic factors, there are other clinical and epidemiological factors associated with rapid progression to AIDS such as being female, non-use of condon, oral candiasis, T cell CD4+ count and viral load. All of them must be taken into account at the moment of initial patient assessment.
