NCWS or IBS/FD in Relatives of CD Patients

Summary

Over 50% of non-celiac wheat sensitivity (NCWS) patients are HLA DQ2/DQ8 positive and often have a Celiac Disease (CD) family history. Studies have identified a subgroup of NCWS patients whose clinical and immunological features are closer to CD than to irritable bowel syndrome/functional dyspepsia (IBS/FD) ('inflammatory subgroup'). The investigators hypothesized that among CD patient's relatives, there might be a high number of NCWS subjects, who hypothetically belong to the 'inflammatory subgroup'. Therefore, the aim of this multi-step project is to identify the prevalence of both self-reported NCWS and IBS/FD not related to wheat ingestion among CD patient's relatives (parents, grandparents, siblings and sons).

Conditions

  • Non Celiac Wheat Sensitivity
  • IBS (Irritable Bowel Syndrome)
  • Functional Dyspepsia
  • Celiac Disease

Interventions

OTHER

Wheat-Free Diet

Patients, identified at T1, will undergo a 6-week long strict WFD (preliminary dietician consul will be granted to all subjects), at the end of which (T2) they will fill-out an online form including a WFD adherence questionnaire (i.e. modified 'Biagi' score) and the questionnaires reported in WP1. Patients reporting a reduction ≥30% in at least one questionnaire after WFD will be identified as self-reported NCWS, all the others will be identified as IBS/FD not related to wheat intake.
