[Cytomegalovirus disease in patients with acquired immunodeficiency syndrome. Report of 63 cases].

BACKGROUND

The aim of the present was to study the clinical and therapeutic characteristics of patients with the human immunodeficiency virus (HIV) with disease by the cytomegalovirus (DCMV) observed between 1984-1990. Some concrete aspects such as viremia by the cytomegalovirus (CMV) without focal disease or the profitability of cultures of different samples as predictors of DCMV were analyzed.

METHODS

The clinical records of the patients diagnosed with DCMV as well as cultures of blood, saliva, and urine CMV of the global collective of patients with HIV were retrospectively studied.

RESULTS

Sixty-three episodes of DCMV were collected in 41 patients corresponding to 29 episodes of retinitis by CMV (46%), 8 with digestive involvement (13%), 7 with lung involvement (11%), 18 with fever without focality and viremia by CMV 9 (29%) and 1 of encephalitis by CMV (1.5%). Eighty percent of the patients had been previously diagnosed of AIDS. The mean of CD4 lymphocytes was 43 cells/mm3 and the estimated probability of survival at 12 month was 18%. In 89% of the episodes of retinitis and 87% with digestive involvement improvement was achieved with treatment. Retinitis developed a posteriori in 38% of the patients with viremia without focality. During the period studied, 105/244 (43%) of the patients with the HIV showed some sample positive for CMV. Sixty-four percent of the patients with positive cultures in urine and/or saliva did not present DCMV after prolonged follow up.

CONCLUSIONS

Cytomegalovirus disease is produced in advanced phases of infection by the human immunodeficiency virus. Response to treatment was good in cases of retinitis, digestive involvement and symptomatic viremia without focality. The symptomatic viremia by cytomegalovirus constitutes a predictor of localized disease. Positivity of urine and saliva cultures has slight predictive value for cytomegalovirus disease in patients with the human immunodeficiency virus.
