Reduced Content of Gluten Diet on Patients With Irritable Bowel Syndrome (Pro.Ali.Fun.) (PROALIFUN)
August 15, 2018 updated by: Ruggiero Francavilla, University of Bari
Effect of Wheat Bread and Pasta With Reduced Content of Gluten on Patients With Irritable Bowel Syndrome: Randomized Controlled Cross Over Study
This study aim to manufacture bread and pasta with an reduced content of gluten and to assess the impact of reducing the daily intake of gluten by 50% in irritable bowel syndrome (IBS) patients.
Fungal proteases and selected sourdough lactic acid bacteria will be used for making wheat bread and pasta with a reduced content of gluten (RG) (-50% of traditional products).
From a technological point of view, the chemical, structural and sensory features of the RG products approached those of the bread and pasta made with normal level of gluten.
The efficacy and safety of new products will be compared to traditional bread and pasta by using a double blind randomized, crossover-controlled trial in IBS patients with persistent gastrointestinal symptoms.
Patients will follow two weeks of a GFD diet containing RG bread and pasta and two weeks of GFD diet containing Normal Gluten bread and pasta Symptoms severity will be assessed by Irritable Bowel Syndrome Severity Score (IBS-SS), Visual Analogue Scale (VAS), Hospital Anxiety and Depression Scale (HADS) and Irritable Bowel Syndrome Quality of Life (IBS-QoL).

ACTIVE_COMPARATOR: Reduced Gluten-Normal Gluten
|
Pasta with low gluten (50% of the normal) content achieved by optimization of techological parameters such as dough yield, time of fermentation and concentration of fungal proteases The gluten reduction is obtained without any other intervention of wheat breeding or the endogenous proteolytic enzymes of flours.

Measure Description |
Time Frame |
---|---|---|
Change in Severity of IBS symptoms measured by Irritable Bowel Syndrome-Severity Score (IBS-SS)
Time Frame: two weeks of each different diet interspersed by one week of wash out. The questionnaire will be completed ones a week.
|
Change in IBS Severity Score (IBS-SS) between reduced gluten content diet and standard gluten content diet.
Mild, moderate and severe cases were indicated by scores of 75 to 175, 175 to 300 and "300 respectively.
Mild, moderate and severe cases are indicated by scores of 75 to 175, 175 to 300, and >300, respectively.
|
two weeks of each different diet interspersed by one week of wash out. The questionnaire will be completed ones a week.
|
Change of IBS severity measured by Visual analogue scale (VAS)
Time Frame: Two weeks of each different diet interspersed by one week of wash out. The scale will be completed ones a day.
|
Change of severity of IBS symptoms measured by Visual analogue scale (VAS) between reduced gluten content diet and standard gluten content diet.
The 0-10 mm VAS scale (0 no pain, 10 worst possible pain) included a horizontal color gradient (green-red).
|
Two weeks of each different diet interspersed by one week of wash out. The scale will be completed ones a day.
