Celiac sprue, also celiac disease (abbreviated CD), is a common pathology that affects the duodenum.
It should not be confused with tropical sprue.
An introduction to gastrointestinal pathology is in the gastrointestinal pathology article. It covers basic gastrointestinal histology.
General
- Considered an autoimmune disease.
- The typical individual with celiac disease has a normal weight or is underweight.
Epidemiology
Associated with:
- Dermatitis herpetiformis - skin condition.[2]
- Tx: dapsone.
- IgA deficiency - 10-15X more common in celiac disease vs. healthy controls.[3]
- Risk factor for gastrointestinal T cell lymphoma - known as: enteropathy-associated T cell lymphoma (EATL).
- IgA nephropathy is associated with an increased frequency of celiac disease.[4]
- Esophageal squamous cell carcinoma - increased risk.[5]
- Small bowel adenocarcinoma - increased risk.[6][7]
- Thought to be related to the very rare collagenous sprue - controversial.[8][9]
- Lymphocytic gastritis - seen in ~10% of individuals with celiac disease.[10]
Variants of celiac sprue
- Latent celiac sprue.
- ONLY intraepithelial lymphocytes.
- NO villous arch. change.
- Refractory celiac sprue.
- Subclassified - see microscopic.
- Collagenous sprue.
- Abundant mucosal collagen - see microscopic.
Clinical
Treatment
- Gluten free diet.
- Mnemonic: BROW = barley, rye, oats, wheat.
Serologic testing
- Anti-tissue transglutaminase (TTG) antibody -- >10 U/mL considered positive.[11]
- Alternative test: anti-endomysial antibody.
- Anti-gliadin antibodies.[12]
- IgA deficiency - associated with celiac sprue.
Microscopic
Features:[13]
- Intraepithelial lymphocytes (IELs) - key feature.
- Loss of villi - important feature.
- Normal duodenal biopsy should have 3 good villi.
- Plasma cells - abundant (weak feature).
- Macrophages.
- Mitosis increased (in the crypts).
- +/-Collagen band (pink material in mucosa) - "Collagenous sprue"; must encompass ~25% of mucosa.
Notes:
- If you see acute inflammatory cells, i.e. neutrophils, consider Giardiasis and other infectious etiologies.
- Biopsy should consist of 2-3 sites. In children it is important to sample the duodenal cap, as it is the only affected site in ~10% of cases.
- Flat lesions without IELs are unlikely to be celiac sprue.
- Mucosa erosions are rare in celiac sprue; should prompt consideration of an alternate diagnosis (infection, medications, Crohn's disease).
- Biagi et al.[14] count twenty cells in five (villi) tips.
DDx
- Giardiasis.
- Have giardia organisms.
- Always consider Giardiasis and especially on exams.
- Crohn's disease.
- Helicobacter gastritis.[17]
- Cryptosporidiosis.[17]
- Whipple's disease (very rare).
- Abundant macrophages should make one suspicious.
- Autoimmune enteropathy - pediatric population.
- Super duper rare.
- Drugs - e.g. olmesartan.[18]
- Morbid obesity.[19]

CD - low mag. (WC/Nephron)
CD - intermed. mag. (WC/Nephron)
CD - high mag. (WC/Nephron)
CD - very high mag. (WC/Nephron)
Celiac sprue. (WC)
Refractory sprue
- Type I: CD3 ~= CD8.
- Type II: CD3 20% + less than CD8.
Grading
Many pathologists do not grade celiac sprue.
Marsh
The Marsh system, also Marsh-Oberhuber:[15]
| Marsh score | Descriptors | Villi | Intraepithelial lymphocytes (IELs) |
Crypts |
| Normal (Marsh 0) | normal | normal villi | < 40 / 100 epithelial cells | normal crypts |
| Marsh 1 | IELs increased | normal villi | > 40 / 100 epithelial cells | normal crypts |
| Marsh 2 | hypertrophic crypts, IELs | normal villi | > 40 / 100 epithelial cells | hypertrophic crypts |
| Marsh 3a | partial villous atrophy / blunted villi (mild) | mild atrophy | > 40 / 100 epithelial cells | hypertrophic crypts |
| Marsh 3b | moderate-to-marked villous atrophy / blunted villi (moderate-to-marked) |
marked atrophy | > 40 / 100 epithelial cells | hypertrophic crypts |
| Marsh 3c | total villous atrophy, flattened mucosa | absent; flat as a pancake | > 40 / 100 epithelial cells | hypertrophic crypts |
Simplified Marsh/Corazza
A simplified Marsh system - based (only) on villous architecture:[16]
| Grade | Similar Marsh grade | Descriptors | Alternate descriptors |
| A | Marsh 1 | well-formed villi, IELs > 25/100 enterocytes | normal villous architecture |
| B1 | Marsh 3a | partial villous atrophy; villous-crypt ratio < 3:1 | blunted villi |
| B2 | Marsh 3c | total villous atrophy | flattened mucosa |
Notes:
- Villous atrophy can be assessed endoscopically.[20]
IHC
- CD3 -- marks the IELs.[14]

Micro
The sections show small bowel mucosa with Brunner's glands. Increased numbers of intraepithelial lymphocytes are present ~ 50 lymphocytes/100 epithelial cells. The villous architecture is within normal limits (no apparent villous blunting).
Neutrophils are present in the lamina propria; however, they are not found intraepithelial.
The epithelium matures normally to the surface (no dysplasia).
