RESUMEN

Para determinar las características epidemiológicas de portadores nasales de Staphylococcus aureus en una muestra de pacientes con VIH/SIDA, se realizó un estudio seccional con 50 pacientes que acudieron a la Consulta de Inmunología, del Hospital “Julio Criollo Rivas” (Municipio Heres, Estado Bolívar, Venezuela), Centro de Referencia Regional, durante enero a diciembre de 2004. Para ello, se tomaron muestras de exudado nasal. Las cepas fueron identificadas mediante la tinción de Gram, catalasa, coagulasa y producción de desoxirribonucleasa. Se encontraron 29 personas portadoras de la bacteria (58%), afectando más al grupo de edad de 33 a 37 años (24.12%), aunque no se obtuvieron diferencias estadísticamente significativas. No hubo predilección por el sexo (p› 0.05). El patrón heterosexual (89.66%), el contacto sexual como vía de transmisión del virus (51.72%), la hipertensión arterial (20.69%), el contaje linfocitario T CD4 mayor a 200 cel/mm³ (75.86%) y la presencia de infecciones estafilocócicas previas (11%) fueron las características epidemiológicas frecuentes en los portadores de la bacteria. Sólo se observó predilección cuando se demostró el contacto sexual y la hipertensión arterial (p›0.05). Se concluye que la cifra de portadores nasales de S. aureus fue alta en este grupo de pacientes.
