RESUMO
Objective To study the clinical characteristics and outcome of cytomegalovirus(CMV) infection in infants.Methods All data including time of infection,clinical characteristics,laboratory tests and outcome of CMV infections in hospitalized infants were collec-(ted) and analyzed from January,1994 to July,2004.Results In 87 infected infants,congenitally infected newborns,perinatal infection in infants and postnatal infection in infants accounted for 27.6%,62.0%,16.6%,respectively.CMV hepatitis was the most frequent type of disease with the incidence of 41.3%,in which the incidence of splenomegaly was 10.3%.Most of CMV hepatitis infants had a good prognosis with the improved rate 80.5%.Central nervous system abnormality(including abnormal intension of muscle,convulsion,ocular and hearing abnormalities) occurred only in congenital and perinatal infection with the incidence of 20.4%.Generalized infection,the incidence of congenital infection and perinatal infection was 16.7%,1.8%,respectively.It did not occur in postnatal infection.The mortality rate of congenital infection and perinatal infection were 12.5% and 1.85%,respectively.Conclusions CMV infection is the main cause of infant hepatitis and it can also cause neurologic sequelae.The outcome of generalized infection in congenital infection is bad and the mortality rate is high.
