Prevalence of sensitization to inhalant allergens in a immunology department from Tegucigalpa, Honduras, 2016

Abstract

Background: Allergic diseases are a public health problem; estimates indicate that between 30% and 40% of the world population is affected by some allergy. Knowing the prevalence of allergen sensitization allows for adequate diagnoses and treatments to be offered. In Honduras there are no studies available in pediatric patients. Objectives: The purpose of this research was to identify the most common types of sensitization in children and their correlation with the most common allergic diseases in patients on immunotherapy at the Maria Hospital of Pediatric Specialties. Methods: Cross-sectional, descriptive, retrospective study in which medical records and databases of patients on allergic immunotherapy at the Maria Hospital of Pediatric Specialties were reviewed between January 2015 and June 2016. Results: 215 children on immunotherapy were assessed; ages ranged from 3 to 18 years, with a mean of 10.8 years. Aeroallergen-positive epicutaneous tests were identified in 73.02%. The most common aeroallergens were Dermatophagoides farinae and Dermatophagoides pteronyssinus mix (96.74%), American cockroach 37.21%, and Aspergillus fumigatus and Homodenderum cladosporioides (16.28%). Conclusions: House dust mites and American cockroach were the most common causes of sensitization in patients on immunotherapy.
