Can Celiac Disease Be Treated?

Yes, celiac disease can be effectively treated with strict, lifelong adherence to a gluten-free diet, which is the only accepted treatment and serves as the "drug of choice" for this condition. 1, 2

Core Treatment: The Gluten-Free Diet

Medical nutrition therapy through a strict gluten-free diet (GFD) for life is the sole accepted treatment for celiac disease. 1 This requires complete elimination of storage proteins found in wheat, rye, barley, and their hybrids such as kamut and triticale. 1, 3

What Must Be Eliminated

• Wheat, barley, and rye must be completely avoided in all forms, including as ingredients, hidden components, and sources of cross-contamination. 3, 4
• Historically, rice, corn, and potatoes served as substitutes, but today nutrient-dense alternatives include buckwheat, amaranth, quinoa, millet, and sorghum. 1, 3

Controversial Foods

• Oats remain controversial but may be acceptable for most patients with celiac disease and can improve nutritional quality. 1, 3 However, oats are not widely recommended in the United States due to concerns about commercial contamination. 1
• Pure oats should be introduced slowly with monitoring for adverse reactions if used. 3

Essential Components of Treatment

Multidisciplinary Team Approach

A registered dietitian must be part of the healthcare team to monitor nutritional status and compliance regularly. 1, 3 Consultation with an experienced dietitian, referral to support groups, and clinical follow-ups for compliance are all recommended. 1

Nutritional Management

Treatment of nutritional deficiency states is essential at diagnosis and during follow-up. 1, 3 Common deficiencies include:

• Iron, folate, vitamin B12 1, 3
• B vitamins, calcium, vitamin D 1, 2
• Zinc, magnesium, and fiber 1

Bone mineral density determination to assess for osteoporosis is recommended as part of initial evaluation. 1, 3

Expected Benefits of Treatment

Compliance with a GFD is protective against development of non-Hodgkin's lymphoma in celiac disease. 1, 3

Treatment results in substantial improvements including:

• Resolution of gastrointestinal symptoms and nutritional deficiencies 1, 5
• Increased bone mineral density, with greatest improvements in the first years of treatment 1, 3
• Improvements in body weight, body mass index, fat mass, bone mass, and biochemical status 1
• Enhanced iron absorption and overall nutritional parameters 1

Monitoring and Follow-Up

Regular follow-up with a healthcare team including physician and dietitian is necessary to confirm diagnosis by objective response and detect noncompliance. 1, 3

Monitoring Methods

• History and serologic testing (tTG-IgA or EMA) to assess adherence is the recommended approach. 1, 2, 3
• Serologic testing is sensitive for major but not minor dietary indiscretions. 1
• In children, histologic improvement occurs quickly; in adults, mucosal healing is slower and less complete. 1
• Verification that clinical abnormalities detected initially have normalized should be confirmed. 3

Management of Non-Responsive Disease

When symptoms persist despite a GFD, systematic evaluation is required:

1. Review dietary history thoroughly for inadvertent gluten ingestion (most common cause). 1, 3

2. Check serologic testing to confirm adherence. 3

3. Search for associated conditions including:

   • Microscopic colitis 1, 3
   • Pancreatic exocrine insufficiency 1, 3
   • Bacterial overgrowth 1, 2
   • Disaccharidase deficiency 1, 2
   • Lactose or fructose intolerance 2

4. Consider complications such as intestinal lymphoma, small bowel strictures, or refractory sprue in persistently febrile or very ill patients. 1

Critical Pitfalls to Avoid

• Never initiate a GFD before completing diagnostic testing (serology and biopsy), as this leads to false-negative results. 2
• Always test for IgA deficiency when performing celiac serology to avoid false-negative results. 2, 3
• Ensure adequate biopsy specimens (multiple samples from duodenum) to avoid missing patchy mucosal lesions. 2
• Monitor for weight gain and obesity, as this has become increasingly common in celiac patients following a GFD. 1, 4

Future Therapeutic Developments

Currently, no pharmacologic alternatives to the GFD are approved for clinical use. 6, 7 Novel treatments including immunotherapy, glutenases, and tight junction regulators are being explored in research phases but remain investigational. 6 Patients should be informed that strict adherence to a GFD remains the only effective treatment available. 6
