Frequent Allergy symptoms in Pediatric Atopic Dermatitis, Eosinophilic Esophagitis Sufferers in Puerto Rico


A latest research in Puerto Rico assessed tendencies amongst pediatric sufferers with atopic dermatitis (AD) and eosinophilic esophagitis (EoE) together with regional tendencies, comorbidities, and customary allergens.

As a persistent pruritic inflammatory pores and skin illness, AD is called essentially the most frequent dermatologic dysfunction for youngsters. EoE, alternatively, is an antigen-mediated, persistent esophageal illness identified to affect 43 of each 100,000 pediatric sufferers within the US.

Flare-ups of EoE and AD may result from dietary and environmental components, which is why they have been seen as vital to evaluate. The research was led by Vylma Velázquez MD, FAAP, FACAAI, from the Centro Medici Episcopal San Lucas.

“This pilot research makes an attempt to establish and examine frequent allergic reactions in pediatric sufferers with AD or EoE,” Velázquez and colleagues wrote. “The aim is to supply physicians with extra outlined knowledge on the connection between allergic reactions and these illnesses in Puerto Rico and the way to apply ambient publicity modifications and dietary restrictions to the Puerto Rican weight loss program.”


The research concerned reviewing the medical information of 138 sufferers in Ponce, Puerto Rico at a selected allergist/immunologist outpatient clinic. The investigators included sufferers who matched the next inclusion standards:

  • RAST IgE-specific or epicutaneous allergy assessments
  • Ages 1 to 18 years
  • Information assessed between December 2016 – 2021

The investigators assessed the presence of each qualitative and quantitative variables in research contributors. They then in contrast the collected knowledge to that of AD and EoE sufferers within the US.


The investigators discovered concerning comorbidities that AD sufferers confirmed statistical significance of allergic rhinitis presence in comparison with EoE, 30.4% and 72.7% respectively. In addition they famous medical relevance of allergic conjunctivitis and bronchial asthma in each teams.

The analysis workforce reported that the allergic reactions with essentially the most statistical significance have been nuts, peanuts, soya beans and walnuts, with prevalence in EoE sufferers versus AD sufferers. The most typical allergens for AD sufferers have been eggs at 36.0%, milk at 32.8%, and wheat at 16.8%. EoE sufferers’ most typical meals allergens have been peanuts at 36.4%, soya beans at 27.3%, and eggs, almonds, nuts, and wheat with equal affected person percentages of 18.2%.

Moreover, the investigators famous that amongst environmental allergic reactions, essentially the most statistically important was cat allergy with prevalence in EoE sufferers in comparison with AD. AD sufferers’ most predominant allergic reactions have been to mud mites, yeast and canine, and EoE sufferers’ most predominant have been mud mites, cats, and pollen.

“When our knowledge was analyzed and in comparison with that of the USA, atopic dermatitis confirmed the identical development as reported throughout the states. In distinction, the prevalence of sensitivities to the most typical allergens have been reported otherwise in our research in sufferers with EoE. Extra sufferers of EoE will probably be evaluated to reassess meals sensitivities and related meals exacerbations.”

The research, “Prevalence of allergic reactions on Pediatric Sufferers with Atopic Dermatitis and Eosinophilic Esophagitis,” was offered at ACAAI 2022.
