TURCHI, Marília Dalva et al. Cytomegalovirus infection in AIDS patients: clinical, virological and histopathological correlations. Rev. Inst. Med. trop. S. Paulo [online]. 1991, vol.33, n.4, pp.243-250. ISSN 1678-9946.

Between April 1986 and June 1987, 50 patients meeting the CDC criteria for AIDS were studied for serological and virological evidence of CMV infection. Attempts for virus isolation from peripheral blood, urine and saliva were performed in cell culture lines of human foreskin fibroblasts and CMV specific IgG and IgM were assayed by IFI and IgG by ELISA. A total of 121 blood, 119 urine and 96 saliva samples were collected. During the study period viremia was noted at least once in 12,5%, viruria in 23,2%, and excretion in saliva in 21,9%. When admitted in the study, 20% (10/50) of the patients had anti-CMV IgM antibodies and 100% (50/50) of them had IgG anti-CMV antibodies (IFI). Five of the 40 patients IgM negative at admission presented anti-CMV IgM antibodies during the study, suggesting CMV reactivation or reinfection. Active CMV infection based on virus isolation and/or IgM positivity was demonstrated in 60% of the patients. Histopathological studies were performed in 24 patients. CMV was found in 50% of the autopsies, mainly in the digestive system, lungs and adrenals. There was no correlation between clinical, virological (serology and isolation) and histopathological diagnosis.
