Background: A growing number of individuals reports symptoms related to the ingestion of gluten-containing food in the absence of celiac disease. Yet the actual prevalence is not well established. Methods: Between April 2015 and March 2016, unselected adults visiting marketplaces, dental practices and a university in The Netherlands were asked to complete a modified validated questionnaire for self-reported gluten sensitivity (srGS). Results: Among the 785 adults enquired, two had celiac disease. Forty-nine (6.2%) reported symptoms related to the ingestion of gluten-containing food. These individuals were younger, predominantly female and lived more frequently in urban regions compared with the other respondents. Symptoms reported included bloating (74%), abdominal discomfort (49%) and flatulence (47%). A total of 23 (47%) srGS individuals reported having had tried a gluten-free or gluten-restricted diet. Abdominal discomfort related to fermentable oligosaccharide, disaccharide, monosaccharide and polyol (FODMAP)-containing food was more often reported in srGS individuals compared with the other respondents (73.5% vs. 21.7%, p < 0.001). Conclusion: Self-reported GS is common in The Netherlands, especially in younger individuals, females and urban regions, although the prevalence was lower than in a comparable recent UK study. It cannot be excluded that FODMAPs are in part responsible for these symptoms.
A small subset of patients with coeliac disease become refractory to a gluten-free diet with persistent malabsorption and intestinal villous atrophy. The most common cause of this condition is inadvertent gluten exposure, but concomitant diseases leading to villous atrophy should also be considered and excluded. After exclusion of these conditions, patients are referred to as having refractory coeliac disease, of which two categories are recognized based on the absence (type I) or presence (type II) of a clonal expansion of premalignant intraepithelial lymphocyte population with a high potential for transformation into an overt enteropathy-associated T-cell lymphoma. Type I disease usually has a benign course that can be controlled by mild immunosuppressive treatment, but type II can be more severe with cladribine with or without autologous stem cell transplantation effective as treatment. Patients who fail to respond to cladribine therapy, however, still have a high risk of malignant transformation. Insights into the immunophenotype of these cells and the recognition that type II disease is a low-grade, no-mass lymphoma opens avenues for new treatment strategies, including chemotherapeutic and immunomodulating strategies. This Review will provide an overview of refractory coeliac disease, discussing mechanisms, diagnosis and management.
Enteropathy‐associated T‐cell lymphoma (EATL) is a T‐cell Non‐Hodgkin Lymphoma which is highly associated with celiac disease. The prognosis of EATL has been considered poor and there are no standardized treatment protocols. Here, we evaluate treatment response and survival of EATL patients in a large multicenter cohort. A total of 61 patients diagnosed with EATL were analyzed. Various treatment regimens were applied in EATL during the past fifteen years including either monotherapy consisting of chemotherapy or resection, or combination therapy with both aforementioned regimens whether or not combined with stem‐cell transplantation (SCT). Overall, 50/61 patients (82%) died after a median of 7.4 months. One‐ and five‐year overall survival was 40 and 11%, respectively. Median follow‐up in the survivors was 26 months. Patients treated with the most aggressive treatment, that is, resection, chemotherapy and autologous SCT, showed the most favourable outcome with complete remission in all patients, the lowest relapse rate and one‐ and five‐year overall survival of 100 and 33%, respectively, although overall survival in this group was not significantly better as compared to patients treated with surgery and chemotherapy. This study indicates that combination treatment is superior compared to monotherapy. Whether or not consolidation therapy with autologous SCT may improve survival needs to be substantiated in a larger randomized international trial. Am. J.

A percentage of ≥14% CD3TCRγδ IEL has a high specificity for CD diagnosis and can be of diagnostic help in cases where diagnosis is not straightforward.
A small subset of coeliac disease (CD) patients experiences persisting or recurring symptoms despite strict adherence to a gluten-free diet (GFD). When other causes of villous atrophy have been excluded, these patients are referred to as refractory celiac disease (RCD) patients. RCD can be divided in two types based on the absence (type I) or presence (type II) of an, usually clonal, intraepithelial lymphocyte population with aberrant phenotype. RCDI usually runs a benign course and may be difficult to be differentiated from uncomplicated, slow responding CD. In contrast, RCDII can be defined as low-grade intraepithelial lymphoma and frequently transforms into an aggressive enteropathy associated T-cell lymphoma with dismal prognosis. This paper describes the clinical characteristics of RCDI and RCDII, diagnostic approach, and the latest insights in treatment options.
