description

• Coeliac disease is a genetically-determined chronic inflammatory intestinal disease induced by an environmental precipitant, gluten.• Patients with the disease might have mainly non-gastrointestinal symptoms, and as a result patients present to various medical practitioners.• Epidemiological studies have shown that coeliac disease is very common and affects about one in 250 people.• The disease is associated with an increased rate of osteoporosis, autoimmune diseases, and malignant disease, especially lymphomas.• The mechanism of the intestinal immune-mediated response is not completely clear, but involves an HLA-DQ2 or HLA-DQ8 restricted T-cell immune reaction in the lamina propria as well as an immune reaction in the intestinal epithelium.

Fallow Up:Fallow Up:

Serologic markers (serum IgA tTG) used to monitor compliance with a gluten-free diet

Antibody levels return to normal within three to 12 months of starting a gluten-free diet.

A repeat small bowel biopsy three to four months after initiation of a gluten-free diet is not necessary if the patient responds appropriately to therapy.

If the patient does not respond as expected despite adherence to a gluten-free diet, the physician should consider diseases that may mimic celiac disease.

Summary:Summary:

People with celiac disease cannot tolerate gluten, a protein in wheat, rye, and barley.

Untreated celiac disease damages the small intestine and interferes with nutrient absorption.

Without treatment, people with celiac disease can develop complications such as osteoporosis, anemia, and cancer.

A person with celiac disease may or may not have symptoms.

Summary:Summary:

Celiac disease is treated by eliminating all gluten from the diet. The gluten-free diet is a lifetime requirement.

A dietitian can teach a person with celiac disease about food selection, label reading, and other strategies to help manage the disease.

If villi are damaged, vitamins, minerals, calcium, carbohydrates, protein, and fats are not absorbed well

Diagnosis involves blood tests and, in most cases, a biopsy of the small intestine.
