A hereditary autoimmune disorder in which the mucosal lining of the small intestine becomes inflamed as a response to the ingestion of gluten, a protein found in wheat and other common food products. The result of the inflammatory reaction is blocked nutritional absorption by the small intestine.
Celiac Disease affects primarily caucasians of northern European descent. It is thought to affect 1st degree relatives at a rate of 10%-20%. The prevalence is estimated to be 1/300 Europeans and 1/250 Americans, with 70% of reported cases occurring in women.
Celiac Disease is commonly manifested in infancy or childhood, with the introduction of food products containing gluten. However, it is not uncommon for the disease to manifest itself into early adulthood. Primary symptoms include diarrhea, chronic diarrhea, abdominal cramping, bloating, indigestion, weight loss, gastric ulceration, and reduced fertility for both men and women. Secondary symptoms, due to malnutrition, include fatigue, depression, nausea, muscle atrophy, changes in bone mineral density, and joint pain. If the problem persists long enough without treatment, excessive nocturnal reabsorption of intestinal fluids can occur, causing nocturia (excessive night time urination). In addition to nocturia, if the condition is severe enough, a gluten-related skin disorder may also be present (dermatitis herpetiformis). Celiac Disease is commonly found in adjunct with Diabetes, Down Syndrome, Turner Syndrome, William Syndrome, Sjogren Syndrome, autoimmune thyroid disorder, autoimmune hepatitis, congenital heart defects, and Addison Disease.
Co-morbidities for Celiac Disease include dermatitis herpetiformis, diabetes mellitus, pernicious anemia, dehydration, hypotension, lymphoma, bowel cancer, microscopic colitis, systemic lupus erythematosus, scleroderma, autoimmune hepatitis, primary biliary cirrhosis, and osteopenia/osteoporosis.
Since the first line of treatment for Celiac Disease is to maintain a gluten free diet, the disease can often result in vitamin and mineral deficiencies from a lack of ingestion of those nutrients from dietary sources. Depending on which nutritional deficiency is present, a person may take over the counter supplements in order to meet personal daily nutritional needs. Hematinics may also be prescribed to stimulate red blood cell volume and to increase hemoglobin availability in order to address blood volume deficiencies. If primary means of treatment prove to be ineffective, corticosteroids can be utilized in order to reduce the inflammatory processes present in the small intestine. 
Diagnostic Tests/Lab Tests/Lab Values
A biopsy from the second portion of the duodenum can verify the presence of pathology in the region, but cannot specifically indicate the presence of Celiac Disease. An abnormal biopsy presents with either histologic changes to surrounding epithelial tissue or by the presence of villous atrophy. Serologic marker testing can also be utilized in order to confirm the presence of Celiac Disease. Anti-tissue transglutaminase antibody (AGA) and anti-endomysial antibody (EMA is an antibody against an intestinal connective tissue protein) are both tested and each have sensitivity and specificity of greater than 90%. A complete blood count (CBC) to test for iron deficiency anemia or folate deficiency anemia is also another common test implemented in the diagnosis and treatment of Celiac Disease. Normal Hematocrit levels include the following values: 36%-40% for children, 40%-50% for males, and 38%-47% for females. Normal Hemoglobin values are indicated as the following: children 11-13 g/dl, adult males 13-18 g/dl, and adult females 12-16 g/dl. Normal platelet levels are between a count of 150,000-450,000 per serum sample. A Schilling test may also be implemented to detect the presence of pernicious anemia (vitamin B-12 deficiency). Urinating out greater than or equal to 9% of the radioactive vitamin B-12 is considered an abnormal value. A basic metabolic profile (BMP) is often implemented in the diagnosis of Celiac disease to ascertain information about blood electrolyte chemistry. This lab profile reveals information pertaining to pathology concerning dehydration and malabsorption by the small intestine. Normal values are as follows: 135-145 mEq/L for Sodium, 96-105 mEq/L for chlorine, 10-25 mEq/L for blood urea nitrogen, 3.5-5.2 mEq/L for potassium, 22-27 mEq/L for carbon dioxide, 0.8-1.2 mEq/L for creatinine, and 70-120 mEq/L for glucose (note: the unit of mEq/L is milliequivalent of indicated compound per liter of total serum sample). The d-xylose absorption test can also be performed to help differentiate intestinal mucosal disease from pancreatic disease. This test reveals information about the integrity of the intestinal mucosal lining. Abnormal absorption is indicated if serum d‑xylose is less than 20 mg/dL or less than 4 g of d-xylose is present in a urine sample. This test is 91% sensitive and specific for detecting small intestine malabsorption. Other tests include a colonoscopy, a barium xray test to detect the presence of malabsorption along the gastrointestinal tract, and a direct stool sample analysis of fat content can also be implemented to detect the presence of steatorrhea (abnormally high fat content contained within expelled fecal matter). Fecal fat greater than 7 grams per day is considered abnormal.
Researchers believe changes in genes HLA-DQ2 and DQ8 to be related to predisposing a person to Celiac Disease, although they believe there are still more genes involved in the development of this disease. In people with the genetic propensity for a gluten reaction, the ingestion of foods containing gluten stimulates gluten sensitive T-cells in the small intestine. The T-cells trigger an inflammatory process in the small intestine which changes the histological makeup of the cells that line the lumen of the small intestine and it causes the villi (hair like projections within the lumen of the small intestine involved in nutrient absorption) to atrophy and eventually to be destroyed.
The small intestine is the primary organ targeted for systemic involvement of Celiac Disease. Abdominal distention, abdominal cramping, nausea, and indigestion are all direct results of systemic involvement of Celiac Disease affecting the small intestine. Malabsorption of ingested nutrients and changes in dietary habits however, can manifest dysfunction throughout the entire systemic system. Changes in bowel and bladder habits are commonly associated with the presence of Celiac Disease. Explosive acute diarrhea, chronic diarrhea, steatorrhea (increased fraction of fecal fat), and nocturia (increased urination at night) are among the symptoms that can occur pertaining to changes in bowel and bladder function related to Celiac Disease. Changes in blood volume can result from malabsorption problems of the small intestine. Hypotension and anemia can often manifest from pathologic changes of blood volume related to malabsorption problems. Fatigue (both central command and peripheral) and an ability to focus conscious attention can result from the brain and entire body not receiving daily nutritional requirements from blocked absorption at the small intestine. In some cases of Celiac Disease, hypertension has also been reported.The issues related to blood volume can vary from person to person, depending on family history, dietary habits, and lifestyle choices of the indvidual. An associated reaction of the epidermis may also be involved. A skin rash known as Dermatitis Herpetiformis can form commonly at the buttocks, knees, or elbows as a direct consequence of Celiac Disease. Other systemic conditions such as polyneuropathy, dilatative cardiomyopathy, psoriasis, and vasculitis may also result from malabsorption.
Medical Management (current best evidence)
The primary treatment for Celiac Disease is maintaining a life long regimen of a gluten free diet. Nutritional supplements are also commonly used in adjunct to maintaining a gluten free diet. This is done in order to make up for nutritional deficiencies that are often present when following a gluten free dietary regimen. The nutritional insufficiencies may vary depending on the dietary habits of the individual. Corticosteroid treatments may also be utilized if the traditional means of treating Celiac Disease are unsuccessful.
Physical Therapy Management (current best evidence)
Celiac Disease is derived solely from pathology involving the enteric system. Physical therapy interventions are designed to address impairments and functional limitations of the musculoskeletal system. There is currently no evidence to support the implementation of physical therapy as a direct interventional method for the treatment of Celiac Disease. However, physical therapy may be implemented in order to treat secondary musculoskeletal conditions that may accompany Celiac Disease. Such conditions include joint pain, muscle atrophy, and osteoporosis/osteopenia. Physical therapists could also assist in educating patients on topics pertaining to physical fitness, dietary recommendations, lifestyle choices, and community resources with refrence to patient needs.
Alternative/Holistic Management (current best evidence)
One alternative approach to treating Celiac Disease is through herbal supplements. Robert's Formula is thought to create a mucosal lining along the lumen of the small intestine that reverses histological lumen changes and villous atrophy. Robert's Formula is advised to be taken intermittently (2 weeks on and 2 weeks off) for a period of up to 2 months. There are also a line of supplements that also can be taken to reduce the local inflammation of the small intenstine caused by Celiac Disease. Turkish rhubarb tea, slippery elm, burdock, sheep sorrel, and pickled ginger are among a few products that posess anti-inflammatory properties that help to reduce the inflammation caused by Celiac Disease. Silica-rich horsetail tea (3 cups) or 15 drops of tincture in liquid three times daily will also help to reduce local small intestine inflammation and strengthen and rebuild connective tissue. Yellow dock herbal teas,dandelion, and saffron are also recommended to purify and nourish circulating blood.
Below is a list of conditions that should be considered in the alternative diagnosis of Celiac Disease. A complete medical history (both subjective and objective), a thorough clinical exam, and extensive laboratory testing should be implemented in the differential diagnosis of Celiac Disease.
