If you take dapsone, you'll need regular blood tests to check for side effects. If you have refractory celiac disease, your small intestine won't heal. Then you'll likely need to be evaluated in a specialized center. Refractory celiac disease can be quite serious, and there is currently no proven treatment.

If you've been diagnosed with celiac disease, you'll need to avoid all foods that contain gluten. Ask your doctor for a referral to a dietitian, who can help you plan a healthy gluten-free diet.
Avoid packaged foods unless they're labeled as gluten-free or have no gluten-containing ingredients, including emulsifiers and stabilizers that can contain gluten.
In addition to cereals, pastas and baked goods, other packaged foods that can contain gluten include:. Pure oats aren't harmful for most people with celiac disease, but oats can be contaminated by wheat during growing and processing.
Ask your doctor if you can try eating small amounts of pure oat products. It can be difficult, and stressful, to follow a completely gluten-free diet. Your physician should be able to order genetic testing. Genetic testing can be done by blood test, saliva test or cheek swab. Genetic testing is expensive with the cost running in the hundreds of dollars, but may be covered by some insurance plans.
First-degree family members unsure about the expense should weigh this against the time and expense of undergoing life-time serologic testing. Gluten-Free Gluten-Free Recipes.
Who should get screened? Children older than 3 and adults experiencing symptoms of celiac disease should be tested First-degree relatives of people with celiac disease — parents, siblings and children have a 1 in 10 risk compared to 1 in in the general population Any individual with an associated autoimmune disorder or other condition, especially type 1 diabetes mellitus, autoimmune thyroid disease, autoimmune liver disease, Down syndrome, Turner syndrome, Williams syndrome, and selective immunoglobulin A IgA deficiency.
The Gluten Challenge If you are currently on a gluten-free diet, your physician may recommend a gluten challenge to allow antibodies to build in your bloodstream prior to testing. Who should have Celiac HLA testing? Related Links Icon. These villi eventually become inflamed and flattened villous atrophy.
Malabsorption of nutrients such as iron, folate, calcium, fat-soluble vitamins A, D, E, and K, and protein can occur, leading to nutritional deficiencies e. The poorly-functioning villi may decrease their production of lactase, an enzyme necessary for digesting lactose, the sugar found in milk. This may result in temporary lactose intolerance. Additional complications of untreated celiac disease include infertility in women and men, miscarriage, lymphoma, and the possible development of other autoimmune diseases.
Symptoms of celiac disease can appear at any age from infancy well into senior adulthood. In the Canadian Celiac Health Survey 1 of 2, adults with biopsy-proven celiac disease, the mean age at diagnosis was 46 years. A gastrointestinal or viral infection, surgery, pregnancy, or severe stress can sometimes trigger onset of the disease.
Medical scientists now recognize that while celiac disease clearly affects the gastrointestinal system, it also affects the musculoskeletal, hematological, endocrine, neurological, cutaneous, and reproductive systems. The symptoms of celiac disease are highly variable depending on age, the duration, and extent of the disease, and the presence of extra intestinal manifestations. Celiac disease may also be associated with other conditions including type 1 diabetes, autoimmune hepatitis, autoimmune thyroid disease, Down syndrome, and Turner syndrome.
The varied presentations of celiac disease and similarities of its symptoms with other diseases often lead to misdiagnoses such as irritable bowel syndrome , diverticular disease , gastric ulcers , allergies, chronic fatigue syndrome, or fibromyalgia. Individuals frequently see numerous physicians before receiving a correct diagnosis. Children with celiac disease may present with gastrointestinal symptoms, such as diarrhea, abdominal pain, vomiting, constipation, abdominal distention, and failure to thrive.
Several extraintestinal symptoms appear to be unique to childhood, and include short stature and delayed puberty. Most patients with celiac disease have a silent form of the illness, lacking examination findings. However, patients occasionally have profound malabsorption with a number of associated clinical findings, such as weight loss and muscle wasting, pallor, stomatitis, or easy bruising.
As previously mentioned, the examination finding most suggestive of celiac disease is dermatitis herpetiformis. The diagnosis of celiac disease is made using a combination of serologic tests, small bowel biopsy, and response to a gluten-free diet Figure 1. The test for endomysial antibodies has higher sensitivity and specificity, but is also more expensive. Tissue transglutaminase tTG testing is of similarly high sensitivity and specificity, but is not as costly.
Thus, IgA tTG is currently the test of choice for serologic diagnosis and monitoring of celiac disease. Algorithm for the diagnosis of celiac disease. Information from references 1 , 2 , 6 , 42 , and When a range is given for sensitivity and specificity, the midpoint was used for the calculations.
Information from references 42 , 44 , and Deaminated gliadin peptide is a newer test for patients who also have IgA deficiency, which is 10 to 15 times more common in patients with celiac disease than in the general population.
Many individuals have detectable but low levels of IgA, and for these persons, the accuracy of IgA-based serologies is thought not to be affected in celiac disease. Serologic tests alone are typically not sufficient to diagnose celiac disease. A small bowel biopsy is required, and persons with a positive serologic test result should be referred for esophagogastroduodenoscopy, as should those with initially negative results in whom there is high suspicion.
Because of the possibility of false-negative results, these tests need to be performed before the initiation of dietary gluten restriction. Many patients initiate a gluten-free diet on their own before a conclusive diagnosis of celiac disease is reached. In severe celiac disease, the effect on serologies and biopsy findings is likely minimal if testing is performed within two months of initiating a gluten-free diet.
Persons with positive serology results who have a diagnosis of celiac disease on intestinal biopsy typically have normal results six to 12 months after the introduction of a gluten-free diet.
Testing results can also be masked when individuals are taking immunosuppressants. The finding of villous atrophy on biopsy is not specific for celiac disease. Therefore, if a patient is not responding to a gluten-free diet, the diagnosis of celiac disease needs to be reconsidered.
Table 5 lists some possible alternative diagnoses. Celiac disease. N Engl J Med. Removing the antigenic substance responsible for the abnormal immune reaction typically reverses the manifestations of celiac disease. Therefore, treatment is a lifelong gluten-free diet 1 , 2 , 6 , 8 , 43 Table 6 3. The dietary threshold to promote healing of intestinal inflammation in celiac disease has been found to be less than 50 mg of gluten per day.
Barley includes malt , rye, wheat includes kamut, semolina, spelt, triticale. Sources of gluten-free starches that can be used as flour alternatives. Cereal grains: amaranth, buckwheat, corn, millet, quinoa, sorghum, teff, rice, montina. Legumes: chickpeas, kidney beans, lentils, navy beans, pea beans, peanuts, soybeans. Dietary education should focus on identifying hidden sources of gluten, planning balanced meals, reading labels, grocery shopping, dining out, and dining during travel.
In addition, appropriate vitamin and mineral replacement may need to be incorporated into the diet. There can be an increased cost associated with this regimen. The Internet has provided easier access to companies selling gluten-free foods, and many grocery stores are focusing on gluten-free substitutes. Meats, dairy products, fruits, and vegetables are gluten free. Oats were once thought to be a trigger for celiac disease; however, investigation has shown that moderate amounts of oats can be safely tolerated, and their introduction can be beneficial in the dietary management of celiac disease.
Not all patients will need each component e. An empiric trial of a gluten-free diet without a biopsy is not recommended because symptoms of other disorders e. Support groups could be helpful with diet maintenance. Repeat endoscopies are not routinely needed, but antibodies can be followed every three to six months until normalization.
