Abstract

Congenital chloride diarrhea is a rare cause of severe infantile diarrhea with excessive chloride excretion. Mutations in the SLC26A3 gene cause congenital chloride diarrhea. It generally becomes apparent in the neonatal period and is characterized by electrolyte imbalances, metabolic alkalosis and failure to thrive. The congenital chloride diarrhea diagnosis is based on detecting excessive chloride in the stool (90 mmol/l). We report about the Turkish neonate with congenital chloride diarrhea whose sibling has the same disease. The newborn was born by cesarean delivery. Diarrhea, womiting and weight loss started soon after birth. She was diagnosed with congenital chloride diarrhea based on its typical clinical sign and a high concentration of stool chloride and was confirmed by genetic analysis. She was treated by means of salt supplementations and lansaprazole. Since the disease is inherited autosomal recessive, family history may play an important role in the early diagnosis.
