Bumetanide, a Diuretic That Can Help Children with Autism Spectrum Disorder.

BACKGROUND

Autism Spectrum Disorder (ASD) is a common child neurodevelopmental disorder, whose pathogenesis is not completely understood. Until now, there is no proven treatment for the core symptoms of ASD. However, some evidence indicates a crucial link between this disorder and GABAergic signals which are altered in ASD. Bumetanide is a diuretic that reduces chloride, shifts gamma-amino-butyric acid (GABA) from excitation to inhibition, and may play a significant role in the treatment of ASD.

OBJECTIVE

The objective of this study is to assess the safety and efficacy of bumetanide as a treatment for ASD.

METHODS

Eighty children, aged 3-12 years, with ASD diagnosed by Childhood Autism Rating Scale (CARS), ⩾ 30 were included in this double-blind, randomized, and controlled study. Group 1 received Bumetanide, Group 2 received a placebo for 6 months. Follow-up by CARS rating scale was performed before and after 1, 3, and 6 months of treatment.

RESULTS

The use of bumetanide in group 1 improved the core symptoms of ASD in a shorter time with minimal and tolerable adverse effects. There was a statistically significant decrease in CARS and most of its fifteen items in group 1 versus group 2 after 6 months of treatment (p-value <0.001).

CONCLUSION

Bumetanide has an important role in the treatment of core symptoms of ASD.
