RESUMEN

Objetivo: dar a conocer antecedentes de la prevalencia de infección por Helicobacter pylori entre sujetos adultos con VIH/sida, en el Hospital de Infectología, Centro Médico Nacional La Raza.
Material y métodos: durante los primeros seis meses de 1993 se estudiaron sujetos portadores de VIH/sida, mayores de 16 años de edad, sin administración de antimicrobianos ni de com-puestos de bismuto durante las cuatro semanas previas, y que autorizaron la endoscopia. Se investigó uso de agua corriente, ingesta de alimentos fuera de su hogar, conducta sexual, uso de antiácidos, síntomas gastrointestinales, motivo de visita al hospital y cuenta de linfocitos T CD4+. Se les realizó biopsias gástricas, de antro, cuerpo y duodeno, para obtener muestras para cultivo de Helicobacter pylori.
Resultados: Se analizaron 49 individuos, 87 % del sexo masculino; la edad media fue de 36 ± 10 años; la mayoría ingería agua corriente (69 %) y alimentos callejeros (75 %). Sólo 24 % aceptó exposición oroanal; 76 % presentaba síntomas, especialmente diarrea y fiebre; la cuenta de linfocitos T CD4+ fue ≤ 200/mm3 en 77 %. Se identificó Helicobacter pylori en 24 individuos (48.9 %).
Conclusión: la prevalencia de Helicobacter pylori en sujetos con VIH/sida fue elevada, a pesar del avanzado estado de inmunosupresión.
