Celiac Disease

Celiac disease is a chronic, systemic, autoimmune-mediated enteropathy triggered by the ingestion of dietary gluten (a protein found in wheat, rye, and barley) in genetically susceptible individuals. It primarily affects the small intestine, leading to mucosal inflammation, villous atrophy, and subsequent nutrient malabsorption.

• Genetic Susceptibility: Strongly linked to human leukocyte antigen (HLA) class II molecules, specifically HLA-DQ2 (95% of patients) and HLA-DQ

• Environmental Trigger: Ingestion of gluten-derived peptides, particularly gliadin.
• Immunological Factors: Autoimmune response coordinated by both innate and adaptive immune systems.

Upon ingestion, gluten is partially digested into proline- and glutamine-rich peptides like the 33-mer gliadin peptide. These peptides cross the lamina propria of the small intestine, where they are deamidated by the enzyme tissue transglutaminase (tTG). Deamidated gliadin possesses a high affinity for HLA-DQ2 and HLA-DQ8 molecules on antigen-presenting cells. Presentation to CD4+ T helper cells triggers an inflammatory cascade characterized by the release of pro-inflammatory cytokines (such as interferon-gamma and IL-15). This process drives intraepithelial CD8+ T-cell infiltration, crypt hyperplasia, and progressive enterocyte destruction (villous atrophy), diminishing the absorptive surface area of the duodenum and jejunum.

• Prevalence: Approximately 1% of the global population.
• Age: Can manifest at any age, from infancy (following gluten introduction) to late adulthood.
• Gender: More frequently diagnosed in females (ratio approximately 2:1).

• First-degree relative with celiac disease
• Type 1 diabetes mellitus
• Autoimmune thyroid disease (Hashimoto's or Graves' disease)
• Down syndrome, Turner syndrome, or Williams syndrome
• Selective IgA deficiency

• General: Cachexia, muscle wasting, or pallor (secondary to anemia).
• Oral Cavity: Aphthous ulcers or dental enamel defects.
• Abdomen: Mild to moderate distension, diffuse tenderness without rebound or guarding.
• Skin: Symmetrical pruritic papulovesicles on the elbows, knees, buttocks, or scalp (dermatitis herpetiformis).

• Clinical Assessment: History of gastrointestinal distress and extraintestinal symptoms.
• Laboratory Testing: Serology and nutritional screening.
• Imaging Studies: Upper endoscopy with biopsy remains the gold standard.
• Biopsy Findings: Duodenal biopsy showing increased intraepithelial lymphocytes, crypt hyperplasia, and villous atrophy (Marsh classification).
• Genetic Testing: HLA-DQ2/DQ8 typing (high negative predictive value).
• Differential Diagnosis: Irritable bowel syndrome (IBS), non-celiac gluten sensitivity (NCGS), tropical sprue, Crohn’s disease.

tTG-IgA (Tissue Transglutaminase IgA)

• Type: Blood Test


• Purpose: Primary screening test for celiac disease.


• Expected Findings: Elevated titers in active disease.


• Interpretation: High sensitivity and specificity; must be performed while on a gluten-containing diet. Total Serum IgA


• Type: Blood Test


• Purpose: Rule out selective IgA deficiency, which can cause false-negative tTG-IgA results.


• Expected Findings: Normal IgA levels.


• Interpretation: If deficient, IgG-based serology (e.g., tTG-IgG or DGP-IgG) must be utilized.

• Upper Gastrointestinal Endoscopy: Used to visualize the duodenum. Typical findings include scalloping of the duodenal folds, fissuring (mosaic pattern), and loss of mucosal folds.
• Clinical Importance: Guided duodenal biopsies (at least 4-6 samples, including the bulb) must be obtained during endoscopy to histologically confirm the diagnosis.

• Irritable Bowel Syndrome (IBS): Presents with bloating and diarrhea but lacks histopathological enteropathy and specific serology.
• Non-Celiac Gluten Sensitivity: Symptomatic response to gluten without positive serology, genetic markers, or villous atrophy.
• Crohn's Disease: Characterized by transmural, patchy inflammation that can affect any segment of the GI tract, unlike the continuous mucosal involvement of celiac disease.

• Refractory Celiac Disease (RCD)
• Osteoporosis and osteomalacia
• Enteropathy-associated T-cell lymphoma (EATL)
• Infertility and low birth weight

The majority of patients achieve complete symptomatic relief and mucosal healing within 3 to 12 months of initiating a strict gluten-free diet. The long-term prognosis is excellent with dietary compliance.

There are no established primary prevention strategies. Secondary prevention focuses on screening high-risk individuals (e.g., type 1 diabetics) to prevent long-term complications.
