Can Congenital CMV-related Hearing Loss be Evaluated Without Systematic Neonatal CMV Screening?
Background: The contribution of congenital CMV infection (cCMV) for permanent hearing loss (HL) may be underestimated without universal cCMV screening. We aimed to determine the contribution of cCMV to permanent neonatal HL in a highly seropositive population, and to verify the proportion of cCMV-related neonatal HL that can be detected by targeting infants who fail universal hearing screening (UNHS) for cCMV testing.
Study design: A total of 11,861 neonates had UNHS and were screened for cCMV by saliva PCR and confirmed by testing urine within 3 weeks of age. Hearing loss was defined by follow up diagnostic audiological evaluation.
Results: Among 11,861 infants, 67 (6 per 1000 live births; 95%CI:4-7 per 1000) were identified with cCMV. Of the 97 (8 per 1000 live births) infants who failed UNHS, 22 (1.8 per1000 live births; 95%CI:1.1-2.8 per 1000) were confirmed with HL. cCMV occurred in 8/22 (36.4%; 95%CI:17.2-59.3) with permanent HL. Among infants who failed UNHS, 9 were CMV-infected; 7 had SNHL, one infant had normal hearing and one did not undergo a hearing evaluation. Of the 11,764 infants (58 with cCMV) who passed UNHS, one with cCMV was confirmed with HL at 21 days. Overall, UNHS identified 7/8 (87.5%; 95%CI:47.3-99.7) infants with cCMV-related HL and missed 1/8(12.5%). The prevalence of cCMV-related HL among CMV-infected infants was 8/66(12.12%). No late onset of HL was detected during a median follow-up of 18 months (range:12-48 months).
Conclusions: One-third of all permanent HL identified by UNHS was related to cCMV. Integrating targeted cCMV screening among infants who fail UNHS will likely identify the majority of CMV-related neonatal HL in this population. However, all infants with delayed onset CMV-related HL may not have been identified because the shorter follow-up.
- To determine the contribution of congenital CMV infection to overall neonatal permanent hearing loss
- To verify the importance of congenital CMV infection as a cause of hearing loss in a highly seropositive population
- To determine the proportion of congenital CMV-related hearing loss that can be detected by targeting infants who fail universal hearing screening for CMV testing.
