Mechanism:Mechanism:
Body attacks normal tissue resulting in damage to lining of small intestinal villi
Villi contain blood vessels which absorb nutrients
Villi increase area for absorption of nutrients

Digested nutrients are carried away by circulating blood
If villi are damaged, vitamins, minerals, calcium, carbohydrates, protein, and fats are not absorbed well

In this subset of patients, research shows that IgG-EMA and IgG-TTG can be detected and are as sensitive and as specific for the diagnosis of celiac disease.

Pathology:Pathology:
many mucosal enzymes are altered due to the damage to the absorptive cells
decrease in disaccharides, peptidases, alkaline phosphatase, ATPase, and esterase Length of small intestine varies from patient to patient
correlates with severity of clinical symptoms
usually proximal small intestine more severely involved

Pathology:Pathology:
Loss of normal villous structure
increase in the number of intraepithelial lymphocytes and gamma/delta T cells
These changes decrease the amount of epithelial surface available for digestion and absorption in the involved bowel

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.
