Triggers for celiac disease: One possible answer

Triggers for celiac disease: One possible answer

Updated 5/2016

triggerWhat triggers celiac disease? How can someone who has eaten gluten their entire life suddenly become ill after ingesting it? Researchers at the University of Chicago Celiac Disease Center may be close to finding an answer to these questions.  This is exciting news, as the discovery of potential triggers may lead to the development of therapies for the prevention of celiac disease.

Genes + Gluten + Trigger = Celiac Disease

In order to have celiac disease, three factors must be present:

Gluten: First, you must be ingesting gluten for the immune reaction to occur. If you never ate gluten, a protein that occurs naturally in wheat, rye and barley, you would never develop celiac disease. The majority of westernized countries are heavily dependent on wheat.  Irrespective of the popularity of the gluten-free diet, the vast majority of Americans consume wheat every day.

Gene: Second, you must carry at least one of two genes (HLA alleles) associated with celiac disease for it to occur. But, having one (or both) of these genes does not guarantee you will get celiac disease.  Thirty to forty percent of the general population carries one of the two genetic markers for celiac disease, but the condition is only triggered in five percent of the people who have a gene for it.

Trigger: The third factor needed for celiac disease to occur is an environmental trigger. Something must activate celiac disease in a person who is consuming gluten and carries the appropriate gene. There is very little data on the environmental factors that may be the trigger(s) for celiac disease but over time researchers have identified some possibilities: pregnancy, illness, menopause, antibiotic use, the anti-acne drug isotretinoin (marketed in the United States under the brand name Accutane until 2009), prolonged use of non-steroidal anti-inflammatories such as ibuprofen, and gastrointestinal infections.

Viral infections as a trigger for celiac disease

virus sickAnother possible trigger not listed above is being investigated at the University of Chicago Celiac Disease Center. Researchers there are evaluating whether or not certain viruses trigger immune reactions that lead to celiac disease in susceptible individuals. The study is ongoing, but what they have found so far is interesting:

• Certain viruses can cause the immune system to “overreact.” If this reaction is prolonged or repeated, it may cause someone to lose the ability to tolerate gluten.

• Different celiac patients had different immune responses to the same infection. This may help explain why symptoms vary so much from one person with celiac disease to another.

• Certain viruses, such as rotavirus, are more likely to trigger these particular immune responses.

Why this information matters to you

If viruses are found to contribute to the development of celiac disease, the discovery could open up avenues for prevention.  We may be able to vaccinate against these viruses and prevent the onset of celiac disease in certain individuals. This may be of particular importance to relatives of people with celiac disease. They are at higher risk for developing the disease. Treatments such as this may sound far off, but a vaccination already exists for rotavirus. If this virus is found to be one of the triggers for celiac disease, a simple vaccination may help prevent celiac disease in susceptible individuals.

Looking ahead

futureAlthough the University of Chicago’s research is not yet published, it appears the authors felt the findings are significant enough to do a preliminary release of their data.   A 2015 review paper also discusses the role that infections and the gut microbiome may play in the onset of celiac disease. This is promising news for the celiac community, as it focuses attention on prevention of celiac disease for future generations. While we are lucky to have the gluten-free diet as a treatment, this may be an important step to a cure.

Testimonials

“I have been a patient of Dr. Amy Burkhart for several years. I suffer from Crohn’s disease and was having difficulty in my daily life. After visiting many doctors, all of whom were unable to help me, Dr. Burkhart took the time and patience to create a plan which brought me back to health. I still follow her plan to this day and have been living a normal healthy life. Dr. Burkhart listened to my symptoms along with listening to me, she took her time in preparing a plan which led me to the road for recovery. I cannot thank Dr. Burkhart enough, and I would recommend her to anyone.”

Just stopped by Project juice for the first time. I was in the Castro in San Francisco but there are many locations. 100% Gluten free juices, bowls, salads, grab and go foods and baked goods. A word of caution: the baked goods are made elsewhere in a non-dedicated facility. GF certified paleo muffins were however available and terrific! Loved the place!
