ICDS Sorrento Postponed to October 19-22, 2022

Following the discussion we had at the last Board meeting, considering the epidemiological uncertainties, the likely difficulties in travelling, the numerous requests received, after further considerations and contacts, the LOC has decided to postpone the Sorrento ICDS to October 19-22, 2022 to ensure the largest possible attendance in person. We invite the Presidents representing SSCD and ESSCD in the Board to inform the members of their Societies. At the next Board meeting we will discuss the impact this may have on the dates of the following ICDS.
It has been a very difficult decision, we hope for the benefit of our scientific community.

Thank you very much for your support.

SSCD STATEMENT ON COVID-19 VACCINATION

With the recent news that the Food and Drug Administration has granted Emergency Use Authorization for a vaccine against SARS-CoV-2, the virus that causes Covid-19, patients with celiac disease are asking for guidance about the advisability of this and other Covid-19 vaccines in the context of celiac disease, an immune-mediated condition. As scientists and clinicians who care for people with celiac disease, we urge people with celiac disease to receive a Covid-19 vaccine that has met government regulatory approval. This includes agents comprised of RNA (a vaccine technology that has been in development and has undergone safety testing for years) and peptide (protein) vaccines.

During the onset of the Covid-19 pandemic, there was initial concern that people with celiac disease might be at a slightly increased risk of severe outcomes from SARS-CoV-2 infection, given prior studies suggesting risks related to pneumonia and viral infections. Studies thus far, including the international registry www.covidceliac.org, have indicated no increased risk of severe outcomes. Even though the risk among people with celiac disease is comparable to that of the general population, we have seen that Covid-19 can nevertheless have devastating effects, and we share in the consensus belief by the public health community that mass vaccination is crucial. As the safety and efficacy data on Covid vaccination has emerged, there is no evidence to suggest that people with celiac disease would be more prone to an adverse effect of vaccination. Celiac disease is not considered an allergy, and by itself does not prompt additional precaution when proceeding with vaccination. Patients with concerns about vaccination and their particular circumstance should speak with their health care provider. We will undergo Covid-19 vaccination as soon as it is offered to us, and we urge our patients to do so.

The advantage of a high-tryptophan diet
Although 40% of the worldwide population express celiac disease susceptibility genes, only 1% will develop the disorder, suggesting a role for environmental factors, including the gut microbiota. Lamas et al. show that celiac disease is associated with an impaired capacity of the gut microbiota to metabolize tryptophan into aryl hydrocarbon receptor (AhR) ligands in patients with celiac disease. Gluten-induced immunopathology in mice expressing a celiac disease susceptibility gene was ameliorated after AhR pathway activation by a high-tryptophan diet, or by treatment with a pharmacological AhR agonist or bacteria producing AhR ligands. AhR pathway modulation by the gut microbiota may have potential as a therapeutic strategy for treating celiac disease.

2021 SSCD ANNUAL BUSINESS MEETING AND GENERAL ASSEMBLY

The SSCD Annual Business meeting will be virtual in 2021. Elections will be held via email ballots. Please check back for the date of this meeting.

To amend the Federal Food, Drug, and Cosmetic Act

On December 11, 2019, Senator Richard Blumenthal [D-CT] introduced S.3021, to the Senate floor. This bill is meant to amend the Federal Food, Drug, and Cosmetic Act to require the label of a drug that is intended for human use and contains an ingredient that is derived directly or indirectly from a gluten-containing grain to identify each such ingredient, and for other purposes. It will also be known as the Gluten in Medicine Disclosure Act of 2019 and uses the same language as H.R. 2074, the bill Representative Tim Ryan [D-OH] introduced to the House in April.

If passed, the bill would amend the Federal Food, Drug, and Cosmetic Act to require gluten be labeled in all medications.

Read the bill.

How You Can Help

Beyond Celiac encourages you to support the Gluten in Medicine Disclosure Act of 2019 by contacting your representatives and encouraging them to cosponsor this bill. A list of those currently cosponsoring this bill can be found here.

1. Call, write, email, or send a message to your Senators and Congressional reps urging them to cosponsor this and the corresponding House bill. Include a personal story.

2. Set up district meetings as Senators are back home during recesses.

3. Attend local events and talk to their your Senators and their staff at the events urging them to cosponsor.

NANOPARTICLES SHOW PROMISE AS A TREATMENT FOR CELIAC DISEASE

New study suggests gluten could be prevented from triggering the damaging immune reaction

By Amy Ratner, Medical and Science Research News Analyst

A potential treatment for celiac disease in which nanoparticles act like a Trojan horse and carry a hidden component of gluten to reprogram the immune system not to react has shown positive early results in a new clinical trial.

Commentary: Safety of Adding Oats to a Gluten-free Diet for Patients with Celiac Disease: Systematic Review and Meta-analysis of Clinical and Observational Studies

It can be difficult to follow a strict gluten-free diet after being diagnosed with celiac disease. Oats, compared to other cereals like wheat, are a source of good quality proteins, vitamins and minerals and they improve palatability and the texture of gluten-free food. For a person diagnosed with celiac disease, adding oats to a gluten-free diet could not only increase food options, but also help them follow a better gluten-free diet and have a higher quality of life. However, issues have been raised regarding potential adverse reactions to oats by celiac patients and this has reduced the enthusiasm of adding oats to the gluten-free diet in many cases. For this reason, SSCD members decided to perform a meta-analysis to evaluate the evidence regarding the safety of adding oats to a gluten-free diet in celiac disease.

The study, published in Gastroenterology (April 18, 2017, article/S0016-5085(17)35474-4), found no evidence that addition of oats to a gluten-free diet affects symptoms or activates celiac disease. However, it is very important to stress that there were few studies in some of the analyses, the quality of the studies was low and most of them were conducted outside of North America. This means that although the [general] consensus is that pure (not contaminated with gluten) oats are safe for most patients with celiac disease, contamination with other cereal sources that may contain gluten, needs to be avoided. The purity of oats will depend on the country of origin and local regulations and, therefore, we were surprised to see that most recommendations in North America are still based on studies performed in Europe. The study raises the need for well-controlled studies in North America, using locally sourced oats.
