[Acquired cytomegalovirus infections in immunocompetent adults: 116 cases].

OBJECTIVE

To analyse retrospectively the clinical, biological and epidemiological features of cytomegalovirus (CMV) infection in the immunocompetent host.

PATIENTS AND

METHODS

A retrospective study was conducted in 116 cases of CMV infection (74 inpatients, 42 out-patients) collected from 1981 to 1997 in a university hospital. Diagnostic was established on serological criteria in all cases.

RESULTS

Fever was observed in all cases but one (mean duration: 21 days). The most frequent symptoms were headache (51%) and myalgia (46%). Splenomegaly was the most frequent sign (36%). Pulmonary interstitial opacities on chest x-ray were found in 8.5% of patients. Pulmonary (1 case) and neurological (2 cases) complications occurred. Concomitant HIV primary infection was observed in 2 patients. Mononucleosis and ALAT and LDH elevations were observed in 95%, 85% and 95% of cases respectively. Viremia was positive in 79% (30/38). pp65 antigenemia was useful to establish the diagnosis in 9 patients. Antibiotics were prescribed in 46% before diagnosis was established.

CONCLUSION

CMV infection in the immunocompetent host is a frequent and rarely complicated disease. pp65 antigenemia should be evaluated more in this setting. Most hospitalizations due to this affection could be avoided.
