The mother states his pediatrician first noticed impaired growth around 12 months of age. The mother also noticed his abdomen looked more distended over the last few months and he is more irritable than usual. She describes a vague history of looser stools without overt hematochezia. Pediatric gastroenterology was consulted and sent blood work which was remarkable for mild anemia and positive anti-tissue transglutaminase immunoglobulin A antibodies (TTG IgA). The patient underwent an upper endoscopy with biopsies, which was visually remarkable for erythematous duodenal mucosa with scalloping of the intestinal folds (Figures 60-1 and 60-2).
