Autoimmune and Allergic Disorders are More Common in People With Celiac Disease or on a Gluten-free Diet in the United States

GOALS

We analyzed demographics, lifestyle patterns, and clinical characteristics of people with celiac disease (CD) and people without CD avoiding gluten (PWAG) to better understand associations with medical conditions and consumer behavior.

BACKGROUND

Clinical significance of CD and gluten avoidance in the general population is incompletely understood. Recently, a high incidence of CD in adolescents with susceptibility genotypes, similar to other autoimmune or allergic disorders, and regional differences in consumer practices of gluten avoidance were reported.

METHODS

Among 22,277 participants in the National Health and Nutrition Examination Survey 2009-2014, we identified persons with CD by testing CD serology or by both a health care provider diagnosis and adherence to a gluten-free diet. Similarly, PWAG were defined as adherent to a gluten-free diet without a CD diagnosis. Consumer behavior and characteristics of both groups, CD and PWAG were compared with those without these conditions, using survey-weighted generalized logistic regression.

RESULTS

Participants with CD considered nutrition very important when grocery shopping and tended to have more constipation and thyroid disease. PWAG tended to spend more money on groceries, purchase organic foods, and check food labels more frequently during grocery shopping. They also reported having more food allergies, asthma, and thyroid disease.

CONCLUSIONS

Our study confirms that CD and PWAG share comorbidities of autoimmune nature. PWAG had more autoimmune/allergy-related disorders that may be associated with non-celiac gluten sensitivity a self-justifiable reason to be on the diet.

The Revival of the Battle between David and Goliath in the Enteric Viruses and Microbiota Struggle: Potential Implication for Celiac Disease

The human gut is inhabited by overcrowded prokaryotic communities, a major component of which is the virome, comprised of viruses, bacteriophages, archaea, eukaryotes and bacteria. The virome is required for luminal homeostasis and, by their lytic or synergic capacities, they can regulate the microbial community structure and activity. Dysbiosis is associated with numerous chronic human diseases. Since the virome can impact microbial genetics and behavior, understanding its biology, composition, cellular cycle, regulation, mode of action and potential beneficial or hostile activities can change the present paradigm of the cross-talks in the luminal gut compartment. Celiac disease is a frequent autoimmune disease in which viruses can play a role in disease development. Based on the current knowledge on the enteric virome, in relation to celiac disease pathophysiological evolvement, the current review summarizes the potential interphases between the two. Exploring and understanding the role of the enteric virome in gluten-dependent enteropathy might bring new therapeutic strategies to change the luminal eco-event for the patient’s benefit.
