Abstract:
Objective:To investigate the human cytomegalovirus(HCMV)infection and hearing impairment in infants with congenital and perinatal diseases of the Bo′ai Hospital in Zhongshan City, and to explore the risk factors of hearing impairment and clinical outcomes.Methods:A total of 243 cases of infants with congenital and perinatal HCMV infection were collected from Bo′ai Hospital from January 2016 to December 2018.Clinical data and brainstem auditory evoked potential(BAEP)results were analyzed retrospectively.Logistic regression analysis was performed to identify the risk factors of hearing impairment.The children with hearing loss were followed up in out-patient.Results:Positive rates of congenital and perinatal HCMV infection in infants were 4.56%(121/2654), 2.76%(74/2686)and 3.15%(85/2701)from 2016 to 2018 in our hospital respectively.In 243 cases, there were 107 cases with normal hearing(44%), 33 cases with suspicious hearing impairment(14%)and 103 cases with hearing impairment(42%). Multivariate logistic regression analysis showed that the age less than 1 month( P=0.034)and CMV-DNA positive( P=0.003)were independent risk factors for hearing impairment.The manifestations of hearing impairment were various.Twenty cases with suspected hearing impairment were not treated with ganciclovir, in which 19 cases BAEP became normal.Sixty-seven cases with hearing impairment were followed up, of whom 47 cases received standardized ganciclovir antiviral therapy: 30 cases returned to normal, and 12 cases improved, and 3 cases showed no significant changes, and 2 cases aggravated.Twenty cases did not received the antiviral therapy: 5 cases returned to normal, and 8 cases improved, and 3 cases showed no significant changes, and 4 cases aggravated. Conclusion:There was a high rate of HCMV infection of congenital and perinatal infants in our hospital.Infected infants have a higher proportion of hearing impairment.Infants less than 1 month and CMV-DNA positive are more likely to suffer from hearing impairment.It can be considered for clinical observation for the cases with slightly elevated hearing threshold.Standardized ganciclovir antiviral therapy has obvious effect on hearing improvement.
