Tufting Enteropathy: A Review of Clinical and Histological Presentation, Etiology, Management, and Outcome

الملخص EN

Congenital tufting enteropathy (CTE), also named intestinal epithelial dysplasia, is a rare, autosomal recessive enteropathy with persistent and life-threatening intractable diarrhea early in life.

Intractable diarrhea is present independent of breast or formula feeding.

Most CTE patients require total parenteral nutrition (TPN), and in severe cases, small bowel transplantation is needed.

In the last decade, we have seen remarkable progress in certain aspects, such as the pathogenesis and diagnostic methods of the disease.

Rapidly developing molecular analysis techniques have improved the diagnostic methods for CTE and reduced invasive and expensive procedures.

Mutations in the gene encoding human epithelial cell adhesion molecule (EpCAM) were identified in the typical form of CTE, which usually exhibits isolated refractory diarrhea.

Moreover, the syndromic form of CTE features anal and choanal atresias as well as ophthalmologic signs, which are associated with mutations in the gene encoding Serine Peptidase Inhibitor Kunitz Type 2 (SPINT2).

This article reviews CTE disease based on its clinical and histological presentation, etiology and pathogenesis, and management and outcome.
