Celiac disease is a condition in which the small intestine is damaged by gluten, the storage protein of wheat and similar proteins in barley and rye. The disease can cause different symptoms such as diarrhea, bloating, abdominal pain and weight loss. The majority of patients respond to a gluten-free diet. However some patients (5-30%) have persistent symptoms and are considered to be poor responders to the diet. Bacterial overgrowth in the small intestine accounts for some of the refractory patients.
This study seeks to determine if antibiotic therapy with rifaximin relieves the symptoms of patients who are poorly responsive to a gluten-free diet and whether this impacts their breath test results.
A symptom questionnaire will be administered at study initiation, 2 weeks and 12 weeks. Patients will undergo a breath test which involves drinking a sugar (lactulose) solution and breathing into a machine. This technique will identify the presence of bacteria in the small intestine. They will be randomly selected to receive either an antibiotic (rifaximin) or placebo three times a day for 10 days to treat their bacterial overgrowth.

This study is to see if a high response to the TTG screening test for celiac disease is as accurate as the current method of diagnosing celiac disease which entails a general anesthetic an...
Background/Aim: Celiac disease is a common immune-mediated disorder, and the only currently available treatment is a gluten-free diet. Recent studies have shown several probiotics to carry...

A complex network of nerve fibers including sympathetic and parasympathetic efferents and visceral afferents. The celiac plexus is the largest of the autonomic plexuses and is located in the abdomen surrounding the celiac and superior mesenteric arteries.
Simple protein, one of the prolamines, derived from the gluten of wheat, rye, etc. May be separated into 4 discrete electrophoretic fractions. It is the toxic factor associated with CELIAC DISEASE.
Human immune-response, D-related antigen encoded by the D locus on chromosome 6 and found on lymphoid cells. It is in linkage disequilibrium with HLA-A1 and HLA-B8. The HLA-DR3 antigen is strongly associated with celiac disease, Grave's disease, dermatitis herpetiformis, early-age onset myasthenia gravis, systemic lupus erythematosus, juvenile diabetes, and opportunistic infections in AIDS.
Human immune-response, D-related antigen encoded by the D locus on chromosome 6 and found on lymphoid cells. It is strongly associated with celiac disease and psoriasis vulgaris.
A malabsorption syndrome that is precipitated by the ingestion of GLUTEN-containing foods, such as wheat, rye, and barley. It is characterized by INFLAMMATION of the SMALL INTESTINE, loss of MICROVILLI structure, failed INTESTINAL ABSORPTION, and MALNUTRITION.
