Antiviral therapy
-
Congenital cytomegalovirus (CMV) infection is one of the most common infectious causes of congenital sensorineural hearing loss. To date, a safe and effective therapy for CMV-induced hearing loss does not exist. We hypothesize that the antiviral cidofovir (CDV) can be delivered to the inner ear via intratympanic (IT) injections to safely and effectively mitigate CMV-induced hearing loss. ⋯ We provide promising evidence demonstrating both the efficacy and safety of IT CDV in the guinea pig animal model. This research further establishes a sound framework upon which ongoing investigations into drug delivery mechanisms for CMV-induced hearing loss will be based.
