Society for the Study of Celiac Disease position statement on gaps and opportunities in coeliac disease.

Progress has been made in understanding coeliac disease, a relatively frequent and underappreciated immune-mediated condition that occurs in genetically predisposed individuals. However, several gaps remain in knowledge related to diagnosis and management. The gluten-free diet, currently the only available management, is not curative or universally effective (some adherent patients have ongoing duodenal injury). Unprecedented numbers of emerging therapies, including some with novel tolerogenic mechanisms, are currently being investigated in clinical trials. In March 2020, the Celiac Disease Foundation and the Society for the Study of Celiac Disease convened a consensus workshop to identify high-yield areas of research that should be prioritized. Workshop participants included leading experts in clinical practice, academia, government and pharmaceutical development, as well as representatives from patient support groups in North America. This Roadmap summarizes key advances in the field of coeliac disease and provides information on important discussions from the consensus approach to address gaps and opportunities related to the pathogenesis, diagnosis and management of coeliac disease. The morbidity of coeliac disease is often underestimated, which has led to an unmet need to improve the management of these patients. Expanded research funding is needed as coeliac disease is a potentially curable disease.

Tax-deductible provisions for gluten-free diet in Canada compared with systems for gluten-free diet coverage available in various countries.

Celiac disease affects 1% of the North American population, with an estimated 350,000 Canadians diagnosed with this condition. The disease is triggered by the ingestion of gluten, and a lifelong, strict gluten-free diet (GFD) is the only currently available treatment. Compliance with a strict GFD is essential not only for intestinal mucosal recovery and alleviation of symptoms, but also for the prevention of complications such as anemia, osteoporotic fractures and small bowel lymphoma. However, a GFD is difficult to follow, socially inconvenient and expensive. Different approaches, such as tax reduction, cash transfer, food provision, prescription and subsidy, have been used to reduce the additional costs of the GFD to patients with celiac disease. The current review showed that the systems in place exhibit particular advantages and disadvantages in relation to promoting uptake and compliance with GFD. The tax offset system used in Canada for GFD coverage takes the form of a reimbursement of a cost previously incurred. Hence, the program does not help celiac patients meet the incremental cost of the GFD - it simply provides some future refund of that cost. An ideal balanced approach would involve subsidizing gluten-free products through controlled vouchers or direct food provision to those who most need it, independently of 'ability or willingness to pay'. Moreover, if the cost of such a program is inhibitive, the value of the benefits could be made taxable to ensure that any patient contribution, in terms of additional taxation, is directly related to ability to pay. The limited coverage of GFD in Canada is concerning. There is an unmet need for GFD among celiac patients in Canada. More efforts are required by the Canadian medical community and the Canadian Celiac Association to act as agents in identifying ways of improving resource allocation in celiac disease.

The chronic gastrointestinal consequences associated with campylobacter.

Campylobacteriosis is a leading cause of acute infectious diarrhea in the developing world, where it causes considerable mortality, and in developed countries, where it accounts for significant healthcare and other costs. Evidence has emerged from basic science, clinical, and epidemiological domains that suggests that Campylobacter infection is not limited to acute illness but is also involved in the development of well-described extraintestinal sequelae, such as the Guillain-Barré syndrome and reactive arthritis, and may also contribute to the pathogenesis of chronic gastrointestinal conditions. This review will focus on the role of Campylobacter infection as a risk factor for the development of chronic gastrointestinal sequelae, such as functional gastrointestinal disorders, with which irritable bowel syndrome has been most frequently associated, inflammatory bowel disease, and celiac disease.
