RESUMO
Infections from herpes virus play a key role in post-transplantation pathology, so it is indispensable to characterize the group of would-be renal transplant recipients. IgG antibody titers were detected by indirect immunofluorescence to Herpes simplex virus, Epstein Barr virus (EBV) and cytomegalovirus (CMV) in 100 patients treated with hemodialysis in the Nephrology Institute. The prevalence of antibodies to cytomegalovirus and to Herpes simplex and Epstein Barr viruses was 100 and 95 respectively. Average geometric titers (AGT) of antibodies to CMV were significantly higher. There was no correlation between AGT and sex, age, time of disease remission, number of blood transfusions and number of transplants.

Se utilizó la técnica de reacción en cadena de la polimerasa (RCP) múltiple para detectar, en un solo tubo de reacción, la presencia del virus de herpes simple (VHS), citomegalovirus (CMV), virus de Epstein Barr (VEB), virus de la varicela zóster (VVZ) y/o el virus del herpes humano 6 (VHH6). Cincuenta líquidos cefalorraquídeos de pacientes con el síndrome de inmunodeficiencia adquirida y con sospecha clínica de meningoencefalitis por el VHS, recibidos en el Laboratorio de Enfermedades de Transmisión Sexual del Departamento de Virología del Instituto de Medicina Tropical "Pedro Kourí" entre los años 1993 y 1996 fueron analizados; de estos,4 resultaron positivos al VHS, 3 a CMV, 2 al VVZ y 1 al VHH6, para 20 por ciento de positividad. Se correlacionaron los resultados de la RCP con los hallazgos clínicos que presentaban los pacientes en el momento que se les realizó la punción lumbar. La introducción de esta técnica en el laboratorio permite contar con una herramienta útil, por su sencillez y rapidez para el diagnóstico de las meningoencefalitis por herpesvirus

We have standardized an indirect ultramicro ELISA assay for detecting antibodies to human Cytomegalovirus (CMV) using human serum samples (UMELISA CMV). The optimal concentration of coating antigen (30 ug/ml), serum dilution (1:40) and anti-human conjugate working dilution (1:1500), were determined by a check board titration method. The UMELISA CMV was compared with the latex agglutination test for antibodies to CMV (Dupont de Nemours) and with an indirect immunofluorescent method. The results have showed the high coincidence, sensitivity and especificity of the proposed assay regarding the two methods compared with, and supporting its use either for a blood donors screening or in the serological diagnosis of this infection by paired serum samples.
