Abstract
- Congenital chloride diarrhea is a serious autosomal recessive disease, and defect of intestinal electrolyte absorption that involves, specifically, Cl-/HCO3- exchange in the distal part of the ileum and colon. The clinical feature is dominated by profuse, watery diarrhea containing high concentrations of chloride(> 90 mmol/L) and sodium. The chloride loss results in severe dehydration with a hypochloremic alkalosis. The molecular pathology involves an epithelial Cl - /HCO3 - exchanger protein. Mucosal ion transport is affected to differing degrees and the severity of the disease may thus vary. Recently, a gene defect on chromosome 7 has been identified. However, there was a deficit in replacement of fluid and electrolyte, abdominal distension remained and the character of stools was watery. We report a case of congenital chloride diarrhea in a premature female who presented with watery diarrhea containing high concentrations of chloride and abdominal distension.
