{Abstract}: Hearing impairment in patients with chronic kidney disease (CKD), can affect the quality of life. At present, hearing dysfunction does not have an approved pharmacologic therapy. This study aimed to investigate the protective effects and possible mechanisms of curcumin as a therapeutic agent on hearing impairment in patients with chronic kidney disease. We conducted a randomized controlled trial of 40 chronic kidney disease patients not on dialysis with hearing impairment. Participants were randomly divided into two groups. One group received curcumin daily and the other received a placebo for 12 weeks. The interval between III and V waves, latency of wave V, auditory brain stem response (ABR) threshold, speech reception threshold (SRT), and speech discrimination score (SDS) were evaluated and analyzed before and after the intervention. After treatment, in the curcumin group, III-V waves interval and the latency of wave V were significantly reduced (P value < 0.0001), also ABR threshold was demonstrated a significant improvement (P value < 0.0001). In the trial group, the SDS was increased (P = 0.001) and the SRT was attenuated (P < 0.0001). We had either significant deterioration due to the course of the disease or insignificant changes in the placebo group. Daily administration of curcumin, can significantly improve hearing impairment in CKD patients. Accordingly, curcumin should be considered as a therapeutic option for treating hearing impairment in patients with chronic kidney disease.
