A New Case of Congenital Malabsorptive Diarrhea and Diabetes Secondary to Mutant .

Congenital diarrheal disorders are a group of rare enteropathies that often present with life-threatening diarrhea in the first weeks of life. Enteric anendocrinosis, characterized by a lack of intestinal enteroendocrine cells due to recessively inherited mutations in the () gene, has been described as a cause of congenital malabsorptive diarrhea. Diabetes mellitus also is typically associated with mutations, be it early onset or a later presentation.

Celiac disease screening by immunochromatographic visual assays: results of a multicenter study.

Objective: To assay the efficiency for celiac disease (CD) screening of 2 immunochromatographic visual stick assays based on human recombinant tissue transglutaminase (tTG). One was the antitissue transglutaminase antibodies (AtTGA) stick for IgA/G antibodies to tTG detection, the other was the AtTGA/antigliadin antibodies (AGA) stick for IgA antibodies for tTG and/or gliadins.

Patients And Methods: In a prospective multicenter study, 4 pediatric gastroenterology units from Spain and 2 from Latin America enrolled 72 control children with a normal small bowel mucosa and 113 untreated patients with CD with Marsh type 3 lesions.
