ABSTRACT INFORMATION
Title: 'Sensorineural Hearing Loss in Children with Asymptomatic Congenital Cytomegalovirus Infection Identified through Newborn Screening Followed for up to 18 Years - The Houston Congenital Cytomegalovirus Longitudinal Study' Track: 1 - EHDI Program Enhancement Keyword(s): CMV, asymptomatic, late onset hearing loss, progressive, audiologic follow up Learning Objectives: Describe the proportion of children with asymptomatic congenital CMV infection who are diagnosed with SNHL shortly after birth Describe the proportion of children with asymptomatic congenital CMV infection who are diagnosed with SNHL after a time span of 18 years Abstract: Newborns with asymptomatic cCMV identified through hospital-based screening (positive CMV urine culture within 3 days of life) during 1982-1992 were evaluated using auditory brainstem response, behavioral audiometry, and tympanometry. Sensorineural hearing loss (SNHL) was defined as ?25dB threshold in any frequency, and characterized as progressive or fluctuating-progressive (overall deterioration with intermittent improvement) based on changes ?20dB in any frequency, or ?10dB in the 4-pure-tone-average of 0.5, 1, 2, and 4 kHz, or across any 2 or 3 frequencies in consecutive exams, without middle ear disorder. Of 92 children with asymptomatic cCMV, 82 (89%) were last evaluated at age 9-18 years, of which, 20 (24%) children had SNHL. Nine (45%) children had congenital SNHL, 1 bilaterally and 8 unilaterally; 5 were first evaluated ?3 months and 4 between 4-10 months. Of 8 children who initially had congenital SNHL unilaterally, 5 (63%) developed delayed-onset SNHL in the normal hearing ear, diagnosed at age 6 months in 1 child and between 4-10 years in 4 (80%). Eleven children with initial normal hearing had delayed-onset SNHL, 3 bilaterally and 8 unilaterally; 1 (9%) diagnosed at age 1 year, 4 (36%) between 5-8 years, 5 (45%) between 9-14 years, and 1 (9%) at 17 years. SNHL was progressive in 10 children and fluctuating-progressive in 2. Progression to SNHL >90dB in the worse ear was observed in 9 children. At last evaluation, 2 (2%) of 92 children with asymptomatic cCMV had bilateral SNHL between 40-70dB and 2 (2%) at >70dB. Asymptomatic cCMV is associated with congenital and delayed-onset SNHL that may manifest and progress throughout adolescence. Ongoing long-term audiological follow-up is needed to provide timely interventions and better understanding on the burden of CMV-related SNHL.
