ABSTRACT INFORMATION
Title: 'Hearing Loss in Children with Congenital Cytomegalovirus (CMV) Infection: Findings of Houston Congenital CMV Longitudinal Study' Track: 2 - Audiological Services Keyword(s): Congenital CMV infection, cytomegalovirus, sensorineural hearing loss, longitudinal CMV study Learning Objectives: describe the incidence of hearing loss in a longitudinal study of a cohort of CMV positive children with >10 years of follow-up describe the characteristics of the sensorineural hearing loss pattern among children with congenital CMV infection over a >10-yr period describe the type of audiologic testing used in this longitudinal study Abstract: An estimated 15-20% of cases of bilateral moderate to profound sensorineural hearing loss (SNHL) are attributable to congenital CMV infection. Approximately half of the identified hearing loss cases due to congenital CMV infection are late-onset or progressive. Consequently they are not often detected at birth through newborn hearing screening. We will describe a longitudinal study of 186 infants enrolled in the Houston Congenital CMV Longitudinal Study with more than 10 years of follow-up. Most CMV longitudinal studies are 4 to 5 years long. This study is unique because of the long follow up duration of >10 years. The presentation will report types of data collected, incidence of hearing loss, age of onset, and hearing loss pattern over the study period.
