Pseudo-Bartter syndrome in children with cystic fibrosis.

Cystic fibrosis (CF) is an autosomal recessive genetic disorder. We report a case of a boy aged 4.5 years with cystic fibrosis, presenting under-weightness, hypocalcemia, metabolic alkalosis, hypokalemia, and hyponatremia. Sweat analysis of the patients concluded pseudo-Bartter syndrome, which was successfully treated using antibiotics, physiotherapy, fluids, vitamin supplements, and pancreatic enzyme therapy.
