Cystic fibrosis in Saudi Arabia.

Cystic fibrosis (CF) is generally believed to be rare or nonexistent in Saudi Arabia. The aim of this report is to document the occurrence of CF in Saudi Arabia. Thirteen Saudi children were diagnosed as having CF, evidenced by typical clinical features and elevated sweat chloride concentrations (greater than 60 mmol/l). Duration of symptoms prior to diagnosis varied from 1 month-5 years (mean 23 months). The main clinical manifestations of the children were abdominal distention, failure to thrive, steatorrhoea, hepatomegaly, rectal prolapse and recurrent respiratory infections, often with Pseudomonas aeruginosa. In addition, eight patients with symptoms and a family history highly suggestive of CF, but without confirmatory sweat test results are presented. We hope that this report will increase the awareness of CF and ensure an earlier diagnosis of the disease in Saudi Arabia.
