Subclass of:
Malabsorption Syndrome
Definitions related to collagenous sprue:
-
A malabsorption syndrome characterized by collagenous mucosal lesions of the SMALL INTESTINE, atrophy of MICROVILLI, severe malabsorption, diarrhea, and MALNUTRITION often refractory to a gluten-free diet.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
-
A rare disorder affecting the digestive tract. Its cause is unclear but may be attributed, in part, to increased collagen synthesis without adequate fibrolysis. It is characterized histologically by atrophy of mucosal villi and crypts with extensive subepithelial collagen deposition. Clinical signs include nausea, vomiting, diarrhea and weight loss. Unlike celiac sprue (celiac disease), a gluten-free diet does not predict a certain regression of the disease. The clinical course follows a progression of malabsorption leading to nutritional deficiencies, small bowel ulceration/perforation, lymphoma and infection. Prognosis is usually dismal.NCI ThesaurusU.S. National Cancer Institute, 2021
