A Low FODMAPs Diet in Celiac Patients With Persistent Gastrointestinal Symptoms

Not Applicable

• Conditions: Celiac Disease

• Registration Number: NCT02946827
• Lead Sponsor: Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico

Brief Summary

FODMAPS (fructose, oligosaccharides, monosaccharides, disaccharides and polyols) are characterised as fermentable but poorly absorbed carbohydrates which enter the colon and are utilised by colonic bacteria. During fasting colonic nutrients are scarce but ingesting FODMAPS causes a rapid increase in carbohydrate which can overwhelm the microbiota's ability to utilise substrate. The excess reducing equivalents will generate hydrogen or methane. The principal symptoms are diarrhoea and abdominal distension. Patients with irritable bowel syndrome appear to benefit by restricting intake, possibly because they are hypersensitive to intestinal distension.

The focus of the study is to evaluate if in celiac patients with persistent abdominal symptoms and with a correct gluten free diet, a low FODMAPs diet can improve their symptoms. Moreover the study would like to observe if a dietary restriction in FODMAPs carries the risk of nutritional inadequacy.

Primary Outcome Measures

Name	Time	Method
Improvement of VAS (psychometric response scale level continuous line between two end-points 0-10) values of globel well-being in patients undergoing a balanced Gluten Free/low FODMAPs diet compared to patients in balanced gluten free diet.	21 days

Secondary Outcome Measures

Name	Time	Method
Improvement of VAS values of IBS symptoms in patients undergoing a balanced Gluten Free/low FODMAPs diet compared to patients undergoing only a balanced gluten free diet.	21 days	Evaluated IBS symptoms are: abdominal pain, bloating, satisfaction with stool consistency, epigastric pain, postprandial fullness, early satiety.
Improvement of psychological problems and symptoms of psychopathology through the symptom checklist 90 R (SCL 90 R) in patients undergoing a balanced Gluten Free/low FODMAPs diet compared to patients undergoing only a balanced gluten free diet.	21 days
Evaluation of the dietary intake in micro and macro-nutrients before and after a Low FODMAP diet or a balanced Gluten Free diet through questionnaire.	21 days
Improvement of quality of life assessed through SF-36 questionnaire (eight scale scores) in patients undergoing a balanced Gluten Free/low FODMAPs diet compared to patients undergoing only a balanced gluten free diet.	21 days
