Summary

Osteogenesis Imperfecta-related hearing loss usually occurs in individuals with mild (type I) OI and is much earlier in onset than age-related hearing loss, with the majority of individuals experiencing some minor hearing loss in their 20s. Bisphosphonates have been successfully used to treat otosclerosis, a common cause of hearing loss similar to OI-related hearing loss. As many individuals with OI-related hearing loss also present with otosclerosis and because of their mechanistic similarities, the investigators propose studying the effects of bisphosphonate treatment on individuals diagnosed with both OI type I and hearing loss, thereby determining its effectiveness as a potential treatment for hearing loss.

The investigators will enroll 50 individuals diagnosed with type I OI, ages 18-100, who have documented hearing loss. The investigators will enroll 25 children (6-17 years of age) diagnosed with OI who are currently receiving bisphosphonate treatment as part of their care for orthopedic symptoms. The investigators will also observe 25 children (6-17 years of age) diagnosed with OI who are NOT currently receiving bisphosphonate treatment. The study duration is 63 months (approximately 5 years). Enrollment is anticipated to begin in November 2019.
