Prevalence of congenital adrenal hyperplasia in Kuwait.

Between 1978 and 1988 congenital adrenal hyperplasia (CAH) was diagnosed in 60 children in Kuwait with an estimated prevalence of 1:9,000 livebirths, which is higher than that reported from Europe and Canada. In addition, there was presumptive evidence of CAH resulting in the death of 20 other children, giving a prevalence figure of 1:7000. There were 41 girls (68%) and 19 boys (32%). Thirty-one of the girls (75.6%) and 11 of the boys (57.9%) were saltlosers. Fifty-four patients (90%) were diagnosed as 21-hydroxylase deficient, 3 patients (5%) had a deficiency of the 3 beta-hydroxy-steroid dehydrogenase enzyme, and 3 patients (5%) showed a deficiency of 11 beta-hydroxylase.
