Risk of developing EoE high when other allergic conditions factored in

Among allergic conditions, food allergy had the highest risk of developing EoE

BOSTON (Oct. 24, 2024) – Eosinophilic Esophagitis (EoE), a disorder of the esophagus, is increasingly recognized as a major cause of swallowing difficulties in children and adults. It affects about one in 2,000 people and is part of a spectrum of allergic conditions. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston investigated the probability of patients with certain atopic (allergic) conditions developing EoE.

“We did a separate analysis of four common allergic conditions – asthma, allergic rhinitis, atopic dermatitis and food allergy – to determine the probability of pediatric patients ages 1-18 years with the conditions also developing EoE,” says pediatric resident, Catherine Haber, MD, lead author of the study and ACAAI member. “For each of these atopic conditions, we compared the likelihood of developing EoE with a control group of patients who did not have these allergic or atopic conditions. We found that each of these conditions was  associated with an increased risk of developing EoE. We also found that food allergy had the highest risk of developing EoE among the atopic conditions studied.”

The breakdown for each condition was as follows:

Asthma – 1,885 patients developed EoE versus 726 in the control group who did not Allergic rhinitis – 1,444 patients developed EoE versus 829 in the control group who did not Atopic dermatitis – 533 patients developed EoE versus 307 in the control group who did not Food allergies – 1,098 patients developed EoE versus 166 in the control group who did not The cohort and control groups were matched in terms of sex, race, and ethnicity. Additionally, they were matched for the other atopic conditions included in this study: asthma, allergic rhinitis, atopic dermatitis, and food allergy.

RISK OF DEVELOPING EOSINOPHILIC ESOPHAGITIS WITH PREEXISTING ASTHMA, ALLERGIC RHINITIS, ATOPIC DERMATITIS, OR FOOD ALLERGY
C. Haber*, T. Al-Shaikhly, P. Jhaveri, Hershey, PA.

Introduction: Eosinophilic esophagitis (EoE) is a chronic antigen-mediated disorder of the esophagus leading to esophageal dysfunction that is frequently seen in atopic patients. We investigated the probability of various atopic conditions developing EoE.

Methods: This retrospective cohort study utilized TriNetX US Collaborative Network to identify pediatric patients ages 1-18 years with a diagnosis of asthma, allergic rhinitis, atopic dermatitis, or food allergies from 2016 to 2018. Separate analyses were run for each diagnosis. The control population consisted of patients without the atopy diagnosis who had any documented ICD-10 diagnosis. The cohorts were matched for age at index, sex, race, ethnicity, and the other atopic conditions. The three-year hazard ratio (HR) of developing EoE relative to the controls was calculated.

Results: For the asthma group, there were 1,885 patients that developed EoE versus 726 in the control group (HR 2.35; 95% CI 2.16 – 2.56; p-value <0.001). For the allergic rhinitis group, there were 1,444 patients that developed EoE versus 829 in the control group (HR 1.45; 95% CI 1.34 - 1.58; p-value <0.001). For atopic dermatitis, there were 533 patients that developed EoE versus 307 patients in the control group (HR 1.53; 95% CI 1.33 - 1.76; p-value <0.001). For patients with food allergies, there were 1,098 patients that subsequently developed EoE versus 166 in the control group (HR 6.31; 95% CI 5.36 - 7.43; p-value <0.001).

Conclusion: All atopic risk factors studied were associated with an increased risk of developing EoE. Food allergy had the highest risk of developing EoE.

BOSTON (Oct. 24, 2024) – People have heard for years that climate change is having a significant impact on plant vegetation patterns and influencing how pollen and mold produce. A new study being presented at this year’s American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting in Boston showed that, in Chicago, there has been a significant increase in sensitization to pollens and molds in patients with nasal allergies. “Our goal was to analyze changes in pollen sensitization patterns ...

Pistachios may help improve eye health, new study finds

Pistachios may help improve eye health, new study finds
2024-10-24
A new study1 from researchers at the Friedman School of Nutrition Science and Policy at Tufts University has found that consuming pistachios daily may significantly improve eye health by increasing macular pigment optical density (MPOD), due to the plant pigment lutein, a key factor in protecting the eyes from blue (visible) light and age-related damage. The randomized controlled trial showed that compared to eating a usual diet alone, eating 2 ounces (57 grams) of pistachios per day for 12 weeks as part of a usual diet resulted in a significant increase in MPOD in otherwise healthy middle-aged to older adults. MPOD is an important indicator of eye health, ...

Transcriptomic landscape analysis reveals a persistent DNA damage response in metabolic dysfunction-associated steatohepatitis post-dietary intervention
2024-10-24
Background and Aims Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more advanced form, metabolic dysfunction-associated steatohepatitis, have emerged as the most prevalent liver diseases worldwide. Currently, lifestyle modification is the foremost guideline-recommended management strategy for MASLD. However, it remains unclear which detrimental signals persist in MASLD even after disease remission. Thus, we aimed to examine the persistent changes in liver transcriptomic profiles following ...

Ion-pairing: A new approach to lyotropic chromonic liquid crystal assembly

Ion-pairing: A new approach to lyotropic chromonic liquid crystal assembly
2024-10-24
Self-assembling molecules into organized structures is highly valuable for developing new materials. One notable class of these materials is lyotropic chromonic liquid crystals (LCLCs), which are molecular assemblies of amphiphilic π-electronic molecules, with water-absorbing and water-repelling parts. The term “lyotropic” refers to liquid crystal phases that depend on the concentration of the molecules in a solvent, while “chromonic” indicates that these molecules are stacked into columnar assemblies. In a solvent, these structures are stabilized by π–π interactions and hydrophobic effects. Examples of ...

Popular diabetes and weight-loss drug may reduce risk of Alzheimer’s disease

Popular diabetes and weight-loss drug may reduce risk of Alzheimer’s disease
2024-10-24
CLEVELAND—Researchers at the Case Western Reserve School of Medicine have found that, when compared to seven other anti-diabetic drugs, semaglutide, a popular diabetes and weight-loss drug, may lower the risk of Alzheimer’s disease in people with type 2 diabetes (T2D). Alzheimer’s disease is a brain disorder that slowly destroys memory and thinking skills. According to the Alzheimer’s Association, nearly 7 million Americans 65 and older are living with the disease, and there are more deaths from Alzheimer’s than breast and prostate cancer combined. The study, published ...

Feeding practices play a central role in infants’ rapid weight gain, UNC Greensboro researchers find

2024-10-24
A UNC Greensboro (UNCG) study following 299 women and their infants from pregnancy to toddlerhood examined mul ple psychological, biological, and social factors in the context of infants’ rapid weight gain. They found infant feeding practices associated with obesity, known as obesogenic practices, are strongly correlated with rapid infant weight gain.   Examples of obesogenic practices described in their recent Pediatric Obesity paper include watching television while feeding a baby, formula feeding, and supplementing a bottle with additional foods.   “The key take ...

New AI tool predicts protein-protein interaction mutations in hundreds of diseases

2024-10-24
Scientists from Cleveland Clinic and Cornell University have designed a publicly-available software and web database to break down barriers to identifying key protein-protein interactions to treat with medication. The computational tool is called PIONEER (Protein-protein InteractiOn iNtErfacE pRediction). Researchers demonstrated PIONEER’s utility by identifying potential drug targets for dozens of cancers and other complex diseases in a recently published Nature Biotechnology article. Genomic research is key in drug discovery, but it is not always enough on its own, says Feixiong Cheng, PhD, study co-lead author and director of Cleveland Clinic’s Genome Center. When ...
