Abstract (EN): Background: Fabry disease (FD) is a lysosomal storage disorder (LSD) that involves the cochleovestibular system. Tinnitus and progressive sensorineural hearing loss are frequent complains. A stabilization of hearing function has been reported with enzyme replacement therapy (ERT). This study aims to characterize the inner ear involvement, identify factors associated to hearing loss and evaluate the effect of ERT on the hearing function of FD patients. Methods: We reviewed the clinical records of patients with confirmed diagnosis of FD followed in a Reference Centre on LSD in the North of Portugal. Results: We included a total of 122 patients with a mean age of 47.1 +/- 17.6 years and 48.3% males. Hearing loss was reported by 26.2% of the patients and 23.0% mentioned tinnitus. Pure tone audiometry revealed sensorineural hearing loss in 36.9% of the cases. FD patients presented worse age-adjusted hearing thresholds in all analysed frequencies compared to the normal population (p = .001). Patients with hearing loss presented a significantly higher value of microalbuminuria (p = .001) and a higher frequency of acroparesthesias (p = .032). Patients presented a comparable hearing level one year after starting ERT (p = .384). Conclusions: In FD, hearing loss is common and age-matched hearing thresholds by frequency are worse than in the general population. Hearing loss was associated to the presence of acroparesthesias and higher values of microalbuminuria. Hearing loss stabilized in patients under ERT. A careful cochleo-vestibular evaluation should be part of the clinical assessment of FD.
