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
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]

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]
Sign out
TTG result not available
Duodenum, Biopsy: - Small bowel mucosa with increased intraepithelial lymphocytes, villous architecture and crypt architecture within normal limits, see comment. - Brunner's glands present. - NEGATIVE for acute duodenitis. - NEGATIVE for dysplasia. Comment: Focally, there are approximately 50 lymphocytes/100 enterocytes. Increased intraepithelial lymphocytes is a nonspecific finding that may be seen in a number of conditions, including infections (e.g. Helicobacter gastritis), obesity, and autoimmune disorders (e.g. Crohn's disease). It is seen in celiac disease; correlation with serology is suggested, if not done.

COMMENT: There are approximately 45 lymphocytes/100 enterocytes. Increased intraepithelial lymphocytes is a nonspecific finding.

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).
