Celiac Sprue • Autoimmune disorder precipitated by the ingestion of gluten, found in wheat, barley, and rye • Affects approximately 1% of the population • Immune response to gliadin causes inflammatory reactions, mostly in the upper small intestine • Also called gluten-sensitive enteropathy and nontropical sprue also called gluten-sensitive enteropathy and nontropical sprue
Clinical Manifestations • In adults, women>men • Diarrhea • Abdominal pain or discomfort • Iron-deficiency anemia • Osteoporosis • Others – constipation, neurologic symptoms, dermatitis herpetiformis, hypoproteinemia, hypocalcemia
Diagnosis • Serologic testing (ELISA for IgA) • Antigliadin antibodies (33% PPV) • Antiendomysial antibodies (100% PPV) – endomesium is smooth muscle connective tissue (presence pathognemonic) • Anti tissue transglutaminase antibodies (autoantigen compontent of endomesium) - highly sensitive (95%) and specific (94%) • Small bowel biopsy • Intraepithelial lymphocytosis, mucosal inflammation • Crypt hyperplasia • Villous atrophy • Response to gluten-free diet
Diagnosis • Gold-standard for diagnosis is endoscopic intestinal bx with characteristic features PLUS CD assoc positive serologies World Gastroenterology Organisation (WGO-OMGE). WGO-OMGE practice guideline: celiac disease. Paris (France): World Gastroenterology Organisation (WGO-OMGE); 2007. 18 p.
Treatment • Nutritional therapy (gluten-free diet) • Assess for vitamin deficiencies • Osteoporosis screening
Complications • Intestinal adenocarcinoma • Enteropathy associated T-cell lymphoma • Refractory sprue
