Auditory Brainstem Response in Children with Thalassemia Major under Chelating Therapy.

The present study compared the Auditory Brainstem Response (ABR) of children with thalassemia major and typically developing children. A total of 16 children participated in this study. Group I included 8 children with thalassemia major regularly undergoing blood transfusions and chelating therapy. Group II included 8 age and gender-matched typically developing children. All children in both groups had hearing sensitivity within normal limits. The Auditory Brainstem Response (ABR) was recorded monaurally for click stimuli from both ears. Results showed that the mean latencies of peaks of ABR were similar in both groups. The mean peak amplitude of peaks I and V of the ABR were different between groups, but it was not statistically significant. The present study showed no abnormality in the latency and amplitude of peaks of the ABR in children with thalassemia major with hearing sensitivity within normal limits.
