Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia Clinical Trials Data presented on Clinical Trials Search is not meant to be a substitute for qualified medical advice, visits or professional assistance with a genuine dr.. We are not doctors. Always consult your mD about Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia Clinical research trials and Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia medical trials take place in many of places throughout the U.S.A.. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the effectiveness of new does drugs. The purpose of the studies / projects is to solve specific human healthcare questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to find cures for all varieties of conditions, like Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia. Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia Clinical Trials and other clinical trials allow for volunteers to have health treatment options before they are available to the masses. Many times the human subjects acquire professional assistance for free of charge, and sometimes they are compensated for their time. Occasionally there is a cost for a Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia clinical trial. Test subjects typically obtain the finest healthcare available for their Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia condition. Dangers are a reality, nevertheless, and might include additional or frequent doctor trips, medical dangers (possibly life-jeopardising), and/or the treatment being ineffectual. Trials are federally regulated with strict guidelines to protect clinical trials patients.

Gluten-Free Diet in Patients with Gluten Sensitivity and Cerebellar Ataxia
For Condition: Healthy,Cerebellar Ataxia,Celiac Disease
Status: Completed
Sponsor(s): National Institute of Neurological Disorders and Stroke (NINDS) ,
Synopsis: This study will screen patients with cerebellar ataxia to check for antibodies that indicate allergy to gluten (wheat protein) and will study the effect of a gluten-free diet in patients with these antibodies. Patients with cerebellar ataxia have problems with coordination, resulting in "clumsiness" and unsteadiness of posture and walking. There are many known causes of cerebellar ataxia, but in many patients the cause is unknown and there are no available treatments. Cerebellar ataxia has been recognized as a complication of celiac disease, a syndrome characterized by sensitivity to gluten. Recognizing gluten sensitivity in patients with cerebellar ataxia would be important for two reasons: it would be one of the rare causes of the disease that are potentially treatable, and it would identify patients at risk for developing gastrointestinal cancers, particularly intestinal lymphoma. Patients with cerebellar ataxia of known or unknown cause and normal healthy volunteers of any age are eligible for this study. All participants will have a medical history, physical examination, blood drawn (30 milliliters, or 2 tablespoons) to check for celiac disease antibodies, and possibly other lab tests. This completes the participation of normal volunteers. All patients will have magnetic resonance imaging (MRI) of the brain. This diagnostic tool uses a strong magnetic field and radio waves instead of X-rays to show structural and chemical changes in tissues. During the scanning, the patient lies on a table in a narrow cylinder containing a magnetic field. He or she can speak with a staff member via an intercom system at all times during the procedure. Scanning times vary from 20 minutes to 2 hours. Patients who have celiac disease antibodies will have an upper gastrointestinal (GI) endoscopy intestinal biopsy. For this procedure, a flexible tube is inserted into the mouth and down the throat into the stomach and duodenum (the upper part of the small intestine), where a small tissue sample is taken for microscopic examination. Patients with these antibodies will be put on a gluten-free diet and will be followed at NIH every 3 months for 12 months. On the first visit, patients will have their ataxia evaluated using NINDS's ataxia scale and will meet with a dietitian for instructions for a gluten-free diet. On the second through fifth visits (after 3, 6, 9 and 12 months, respectively, on the gluten-free diet), patients will have their ataxia evaluated, speak with a dietitian to assess their nutritional status, weight, and compliance with the diet, and provide a blood sample for celiac disease antibody testing. At the completion of the study, patients may choose to continue or stop the gluten-free diet. If the ataxia assessments show improvement, patients will be advised to continue the gluten-free diet permanently.
Details: In many patients with cerebellar ataxia, the etiology is unknown. Sensitivity to gluten (wheat protein) has been suggested as a cause for cerebellar ataxia even in the absence of malabsorption symptoms or intestinal pathology. However, the prevalence of gluten sensitivity in patients presenting with cerebellar ataxia is unknown and the effect of gluten-free diet on gluten sensitivity-associated cerebellar ataxia has not been systematically studied. The aim of this project is: 1) To identify gluten sensitive cerebellar ataxia patients attending the Human Motor Control Clinic at the NIH using tests for celiac disease antibodies as a screening method. 2) To conduct open-label controlled clinical trial to assess the efficacy of gluten-free diet in the patients identified using a detailed cerebellar ataxia scale as an objective clinical measure.
