ABSTRACT

Se estudiaron 18 pacientes con sida, que presentaban síntomas gastrointestinales altos o lesiones en la cavidad oral sugestivos de candidiasis. Se obtuvieron datos clínicos, muestras de la cavidad oral, biopsias y cepillado esofágico, así como suero de todos los pacientes. El síntoma que principalmente se observó en la candidiasis esofágica fue la disfagia; la candidiasis oral se comportó de forma asintomática. Candida albicans fue la especie que más se aisló con predominio del serotipo A. Se analizaron por la técnica de electroforesis en gel de poliacrilamida los perfiles proteicos de las 12 cepas pertenecientes a esta especie, se observó identidad de sus patrones de peso molecular, lo que sugiere que sea la misma cepa la que se halla en la cavidad oral y en el esófago. Se evaluó la respuesta de anticuerpos anti-C. albicans, no resultó útil la inmunodifusión doble para el diagnóstico de candidiasis esofágica.


18 AIDS patients who presented high gastrointestinal symptoms or lesions in the oral cavity suggestive of candidiasis were studied. Clinical data, specimen of the oral cavity, biopsies and esophageal brushing, as well as serum from all patients were obtained. Dysphagia was the main symptom observed in the esophageal candidiasis. Candida albicans was the most isolated species with a predominance of serotype A. The protein profiles of 12 strains belonging to this species were analyzed by the polyacrylamide gel electrophoresis, and it was found that their molecular weight patterns were identical, which indicates that the same strain is in the oral cavity and in the esophagus. The response of the anti-C. albicans antibodies was evaluated. The double immunodiffussion was not useful for the diagnosis of esophageal candidiasis.
