Rare confluence: clinically diagnosed Bartter syndrome with sensorineural hearing loss in a young endosulfan-exposed patient

Bartter syndrome, a rare autosomal recessive disorder (1 in 1 000 000), causes salt wasting due to defects in the ion channels of the loop of Henle. In this case report, a young adolescent girl, who is a known case of Bartter syndrome and a recognised endosulfan exposure victim, presented with sensorineural hearing loss and multiple episodes of vomiting. She was treated with intravenous fluids, potassium supplementation and indomethacin. This case highlights the importance of early recognition and routine biochemical investigations to prevent complications of inherited tubulopathies.
