Abstract

Gluten-related disorders have recently been reclassified with an emerging scientific literature supporting the concept of non-celiac gluten sensitivity (NCGS). New research has specifically addressed prevalence, immune mechanisms, the recognition of non-immunoglobulin E (non-IgE) wheat allergy and overlap of NCGS with irritable bowel syndrome (IBS)-type symptoms. This review article will provide clinicians with an update that directly impacts on the management of a subgroup of their IBS patients whose symptoms are triggered by wheat ingestion.
Keywords:

1. Introduction

Non-celiac gluten sensitivity (NCGS), sometimes referred as gluten sensitivity, gluten intolerance, or non-celiac wheat sensitivity, was already described in 1978 but did not receive much recognition from clinicians until the 21st century [1]. It is characterized by intestinal and extra-intestinal symptoms related to the ingestion of gluten-containing food, in subjects that are not affected by either celiac disease (CD) or wheat allergy (WA). This is the original definition based on the Salerno Experts’ Criteria [2]. However, our understanding has evolved since that time and we recognized that the spectrum of symptoms, which occur maybe due not just to the ingestion of gluten proteins but potentially other wheat-related components. In clinical practice, it is crucial to exclude CD in patients who present in this way. A recent PubMed search using the Medical Subject Headings (MeSH) index term of NCGS demonstrates 125 publications prior to 2000 but 490 since the start of the new millennium. Public and commercial interest in a gluten free diet (GFD) has galvanized the scientific community into undertaking research beyond the previously recognized gluten-related disorders such as celiac disease or dermatitis herpetiformis.
Irritable bowel syndrome (IBS) is a common intestinal disorder causing abdominal pain, bloating, gas, diarrhea and constipation. IBS-like complaints are often part of the NCGS clinical picture. Conversely, recent studies support the hypothesis that gluten and other wheat components may trigger IBS symptoms. Due to this overlap and lack of IBS/NCGS biomarkers, and there is a confusing situation for both the primary care physician and the general audience. This review article is aimed to present (1) an update on the complex relationship between NCGS and IBS and (2) the experts’ opinion on this hot topic.
