Summary

Non-celiac gluten sensitivity (NCGS) or 'wheat sensitivity' (NCWS) is included in the spectrum of gluten-related disorders. No data are available on the prevalence of oral lesions in NCWS. Our study aims to evaluate the prevalence of oral lesions in NCWS patients and search for correlations with other clinical characteristics. This prospective observation study will include 90 NCWS patients with irritable bowel syndrome (IBS)- like symptoms, 90 IBS and 90 celiac controls. Patients will be recruited at the Internal Medicine and at the Gastroenterology Units of the University of Palermo. Elimination diet and double-blind placebo controlled (DBPC) wheat challenge proved the NCWS diagnosis. All subjects underwent oral examination to assess the presence or not of oral soft and hard tissue lesions potentially associated to NCWS and CD.

Detailed description

Celiac disease (CD) has been reported to increase the risk of oral lesions. More recently, it has been reported that a consistent percentage of the general population consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have CD or wheat allergy. This clinical condition has been named Non-Celiac Gluten Sensitivity' (NCGS). In a previous paper the investigators suggested the term 'Non-Celiac Wheat Sensitivity' (NCWS), since it is not known what component of wheat causes the symptoms in NCGS patients, and the investigators also showed that these patients had a high frequency of coexistent multiple food hypersensitivity. That previous study also showed a percentage of NCWS patients had weight loss and anemia: whether these depended on the intestinal malabsorption or not remains unclear. As yet no data are available on the presence and prevalence of oral lesions in NCWS patients. The aims of the present study is: 1) to investigate the presence and prevalence of oral lesions in NCWS patient and 2) to search for a possible correlation between oral lesions and other clinical characteristics of NCWS patients.
