Background/Aim: Tufting enteropathy (TE) is a rare cause of congenital intractable diarrhea in children. It often results in an irreversible intestinal failure and total parenteral nutrition (TPN) dependency; eventually, intestinal transplantation may be necessary. Data on TE from the Middle East are scarce; therefore, our aim of conducting this study was to clarify the clinical, histopathologic, and molecular features of TE in Saudi children. Patients and Methods: This was a retrospective chart review of four children with TE who presented between January 2011 and December 2013 to King Fahad Specialist Hospital-Dammam (KFSH-D). The diagnosis of TE was suspected based on characteristic histopathologic intestinal biopsy findings and confirmed by EpCAM gene testing. Results: Molecular testing identified two novel mutations in the EpCAM gene in our patients. These mutations were associated with severe phenotype of the disease characterized by very early onset (median of 2 weeks of life), TPN dependency, and death during early childhood. Two patients died due to central line-related complications. Two patients were referred for intestinal transplantation due to loss of intravenous access in one and progressive liver disease in the other. Conclusion: Mutations in EpCAM gene in Saudi children are characterized by severe phenotype and poor outcome. |
