Filter by:Non-celiac gluten sensitivity (NCGS) is a condition characterized by gastrointestinal and extraintestinal symptoms which are triggered by gluten ingestion in the absence of celiac disease (CD) and wheat allergy. In the last years studies suggested that wheat components other than gluten can be responsible of symptom's triggering, thus the term "non-celiac wheat sensitivity" (NCWS) has been proposed as a more appropriate label. To date, different pathogenetic mechanisms have been proposed, but no conclusive data have been reported; among these, some study groups a possible role of innate immunity and of Natural Killer (NK) cells. KIR (Killer Immunoglobulin-like Receptors) regulate the activation of NK cells through their interaction with Human Leucocyte Antigens (HLA). Both KIR and HLA loci are highly polymorphic, and, in the case of KIR, two main haplotypes have been identified: A and B. Haplotype A is the simplest and correlates mainly with NK inhibition, while haplotype B has a variable number of genes, most of which activate NK cells. The investigators hypothesis is that the genetic variants of KIR, which define the haplotype "inhibitor" or "activator", can affect the development and the course of NCWS too. Thus, the researchers aimed to:1. Identify putative KIR genetic variants in NCWS patients (50 subjects) respect to celiac disease patients (50 subjects) and blood donors (50 subjects); 2. Evaluate the possible association of KIR genetic variants with specific clinical manifestations of patients with NCWS.
Self-reported food hypersensitivity is common, particularly in women, with a reported prevalence of about 20% in the UK community. A wide range of gastrointestinal and systemic symptoms may be experienced related to consumption of the intolerant food(s). In addition, patients demonstrate considerably more generalized subjective health complaints in comparison with healthy controls. In this context, 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 celiac disease 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. In a previous study, the investigators demonstrated, in a population of teenagers, a frequency of self-reported NCWS of about 12%; the frequency of GFD use was 2.9%, which was much higher than the percentage of known CD in the same population (1.26%). The aims of this study were 1) to determine the prevalence of self-perceived wheat and/or gluten-sensitivity in patients undergoing digestive endoscopy, irrespective to the motivations of the test, and 2) to evaluate the demographic and clinical differences between patients self-reporting wheat and/or gluten sensitivity and patients not reporting food hypersensitivity.
In recent years, a new gluten- or wheat-related disease has emerged, a condition labelled "non-celiac gluten sensitivity" (NCGS) or "non-celiac wheat sensitivity" (NCWS). Given the lack of a diagnostic biomarker, NCGS/NCWS mostly remains a diagnosis of exclusion, especially respect to CD and WA, so a confirmatory test is required. The Salerno experts suggested the double-blind, placebo-controlled (DBPC), cross-over, gluten/wheat challenge as the gold standard test to discriminate true NCGS/NCWS patients. There are conflicting data about the real mechanisms which induce symptoms in NCGS/NCWS patients after wheat ingestion. Some Authors suggested a prevalent role for Fermentable Oligosaccharides-Disaccharides-Monosaccharides and Polyols (FODMAPs), rather than gluten in determining the symptoms. Other studies underlined the activation of mechanisms of both innate and acquired immunity in NCWS patients, after wheat ingestion. In the present study, we included a group of consecutive NCWS patients, diagnosed with DBPC wheat challenge, to evaluate a) the frequency of autoimmune diseases, b) the frequency and pattern of serum ANA and other non-organ-specific and/or organ-specific autoantibodies, and c) the possible correlations between autoimmune diseases and serum autoantibodies presence and other NCWS-related disease characteristics, in comparison with age- and sex- matched healthy blood donors and IBS patients unrelated to NCWS.
In the last few years, a new clinical entity has emerged which includes patients who consider themselves to be suffering from problems caused by wheat and/or gluten ingestion, even though they do not have celiac disease (CD) or wheat allergy. This clinical condition has been named non-celiac gluten sensitivity (NCGS), although in a recent article, the investigators suggested the term "non-celiac wheat sensitivity" (NCWS), because it is not known to date what component of wheat actually causes the symptoms. The clinical picture of NCWS is characterized by combined gastrointestinal (bloating, abdominal pain, diarrhea and/or constipation, nausea, epigastric pain, gastroesophageal reflux, aphthous stomatitis) and very different extra-intestinal and systemic manifestations (headache, depression, anxiety, 'foggy mind,' tiredness, dermatitis or skin rash, fibromyalgia-like joint/muscle pain, leg or arm numbness, and anemia). Nowadays, there no data about a possible relationship between gynaecological disorders and food ingestion and food allergy/intolerance. Therefore, the aims of the present study are to investigate 1) the prevalence and characteristics of gynaecological disorders in NCWS patients compared to CD and irritable bowel syndrome (IBS) controls, and 2) the modification of such disorders in NCWS patients after a gluten (wheat)-free diet.

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. Nowadays only few data are available on the histological characteristic of duodenal and rectal biopsies of NCWS patients. The researchers have just demonstrated a significant eosinophils infiltration of the duodenal and colon mucosa, and a significant infiltration of CD45+/CD3-CD14- cells in the rectal mucosa of NCWS patients upon wheat challenge, thus configuring a diffuse gastrointestinal "inflammatory/immunologic" pattern. The aims of the present study are: 1) to investigate the histological characteristics in duodenal and rectal biopsies between NCWS and irritable bowel syndrome (IBS) patients, and 2) to evaluate which site (i.e. duodenal or rectal) shows "inflammatory/allergic" features useful for NCWS histological diagnosis.

Nowadays no data are available on the characteristic of 'rheumatologic' symptoms of NCWS patients. Therefore, the aims of the present study are: 1) to investigate the prevalence of fibromyalgia-like joint/muscle pain in NCWS patient, 2) to search for possible ultrasonographic alterations (i.e. synovitis) of hands and feet joints of NCWS patients, and 3) to evaluate modification of fibromyalgia-like joint/muscle pain in NCWS patients after a gluten free diet period of almost 6 months.
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 celiac disease 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. To our knowledge, there are very few studies which assessed the prevalence of self-reported gluten-related symptoms in the community and analyze diagnostic outcomes in those referred to secondary gastrointestinal care. In one of these, performed in UK, the authors showed that gluten-related symptoms are self-reported by 13% of the population, with 3.7% consuming a gluten-free diet, despite only 0.8% being aware that they have a formal diagnosis of celiac disease. Of those patients presenting to the gastroenterology department, the majority do not have CD but NCWS. No data are available for boys and girls. Therefore, the aims of this study were 1) to determine the prevalence of self-perceived gluten-sensitivity in a population of high-school students, and 2) to evaluate the demographic and clinical differences between students self-reporting gluten sensitivity and students not reporting food hypersensitivity.

Nowadays no data are available on the abdominal ultrasonographic features of NCWS patients. Therefore, the aim of the present study is to evaluate the abdominal ultrasonographic features of NCWS patients in comparison with patients affected with celiac disease.

Lactose intolerance and cow's milk protein allergy (CMPA) are two medical conditions with a very high prevalence in the general population, and there is a large overlap between NCWS symptoms and lactose intolerance and CMPA symptoms. Therefore, the aims of the present study are to investigate 1) the prevalence of positive lactose breath test and DBPC cow's milk protein challenge in NCWS patients with self-reported gastrointestinal symptoms related to milk and/or milk derivates ingestion, 2) the clinical, serological, and histological characteristics of NCWS patients with lactose intolerance and CMPA in comparison to NCWS patients without lactose intolerance and CMPA.
Non-Celiac Gluten Sensitivity (NCGS) has been recently included among the gluten-related diseases. Patients suffering from NCGS are diagnosed after carefully excluding celiac disease (CD), and immunoglobulin E (IgE)-mediated wheat allergy. Then, in the absence of sensitive and specific diagnostic biomarkers for NCGS, a monitoring of the patient during elimination and re-introduction of wheat by a double-blind placebo controlled (DBPC) challenge method has been suggested as diagnostic hallmark. Some studies seem to suggest that wheat components other than gluten can cause the symptoms, and therefore the term "non-celiac wheat sensitivity" (NCWS) has been proposed instead of NCGS. While it is well known that CD is a long-life condition and a strict adherence to the gluten-free diet must be maintained, it is unknown whether this is valid for NCWS. On the year 2012, the researchers published a retrospective study, including 276 patients with irritable bowel syndrome (IBS)-like symptoms who had been diagnosed with NCWS using a DBPC challenge during a ten-years period (2001-2011). The present prospective study aimed to evaluate: A) how many of these patients are still following a wheat-free diet, and B) which percentage was still suffering from NCWS, diagnosed by DBPC wheat challenge, in a subgroup of that cohort.
