Celiac Disease Flashcards
What is celiac disease
- autoimmune disorder that occurs in genetically predisposed people of all ages from middle infancy onward
- gluten-sensitive enteropathy, (protein in wheat, rye, barley)
What dose Celiac disease lead to?
Celiac disease leads to a truncating of the villi lining the small intestine (called villous atrophy) and secondary
to the malabsorption syndrome
Celiac disease - essential factors:
3 essential factors of CD:
- Gluten
- Genetic susceptibility
- Mysterious trigger
Celiac disease - Clinical features:
- Distention and bloating of the stomach
- Loose and greasy stool (steatorrhea)
- Weight loss or failure to gain weight
- Growth failure
- Depression, irritability
- Loss of fat tissue

Celiac disease - Diagnostics:
- Antibody testing
- Small bowel biopsy
- Patho - mechanism - genotype
Celiac disease - Diagnostics: Patho - mechanism - genotype:
- HLA DQ2 in 95% celiac patients
- HLA DQ8 in 5% of celiac patients other family members
- HLA DQ2 / DQ8 in 30-40% of general population
- High impact of negative predictive
^Negative score- DQ2/DQ8 excludes celiac diagnose in 99%
- High impact of negative predictive
Celiac disease - Diagnostics: Small bowel biopsy:
Marsh Staging
1 - increased number of intraepithelial lymphocytes, usually exceeding 20 per 100 enterocytes
2 - proliferation of the crypts of Lieberkuhn
3 - partial or complete villous atrophy
Food allergy diagnosis:
- Patient history
- Food challenge
○ open
○ blind
○ double blind - Skin tests
- Total & specific IgE
Celiac disease - Treatment
- gluten- free diet
○ allowed: corn, rise, buckwheat, millet, potato flour, oats - no gluten for the lifelong (lymphoma prophylaxis)
- additionally milk and lactose free at the beginning (4-6 weeks)
- Manage micronutrient deficiencies (Fe, B1, B6, folate, B12, Zinc)
Celiac disease - Differentials:
- Tropical sprue
- Whipple disease
Celica disease - Complications
- clinical features of malabsorption
- Secondary lactase deficiency
- Adenocarcinoma of the small bowel
- Infertility - potentially in untreated/diagnosed disease
- Osteopenia/ osteoporosis- potentially in untreated/diagnosed disease
Celica disease - Prognosis:
Therapy response
○ Clinical remission: Immediate
○ Serologic response: Weeks-months
○ Mucosal healing: 6-24 months
