NCT01485341

Brief Summary

The idea is to evaluate if the so called "Gluten Sensitivity" is a real clinical entity. Gluten sensitive (GS) persons are defined as those patients, being neither celiac or allergic to weat, who develop symptoms following gluten consumption. This will be achieved by evaluating a global symptom score in GS patients receiving gluten compared to those receiving placebo (primary end point). Symptoms to be evaluated: gastrointestinal (Gastrointestinal Symptom Rating Scale, GSRS); not-gastrointestinal (specifically built evaluation scale); VQV scale, built to evaluate quality of life. Gluten or placebo will be administered daily (10 g) for 15 days; for the 15 days before and 15 after all patients will stay on Gluten Free Diet (GFD). Besides clinical evaluation (each week for 6 weeks), intestinal permeability testing and blood sampling will be requested for the identification of possible markers (serological, gut barrier function, immunological and expression of tight junctions constitutive proteins) that may be of help to differentiate the condition of gluten sensitivity (GS) from that of Celiac Disease (CD)(secondary end point). Inclusion and exclusion criteria for patients enrolling are strictly dependant on the given "Gluten sensitivity" definition. We expect to experience a worsening of gastrointestinal and extra-gastrointestinal symptoms, from hours to days, with an increase in the overall symptom score, above the cut off, in at least 45% of GS subjects enrolled and that have received gluten compared to GS who received placebo.

Outcome Measures

Primary Outcomes (1)

  • Symptoms evaluation according to 3 scales: score after 2 weeks of gluten ingestion

    The evaluation will be made according to the score calculated on the basis of three evaluation scales: "Gastrointestinal Symptom Rating Scale "(GSRS), modified, provides a score ranging MIN=15/MAX=60; Extra-gastrointestinal symptoms evaluation scale, proposed on the basis of the symptoms most frequently observed in GS patients, provides a score ranging MIN=9/MAX=34; VQV scale proposed to evaluate the quality of life, provides a score ranging MIN=16/MAX=64. Total score can be no less than 37 (MIN) and not more than 146 (MAX), with a cut-off of 55.

    Change from baseline at 2 weeks

Secondary Outcomes (2)

  • Bio-Markers to differentiate GS and CD

    Change from baseline at 2 weeks

  • Symptoms evaluation according to 3 scales: scores 2 weeks after completion of intervention

    Return to baseline values at 4 weeks
