Sensitization Profile to Allergens in Patients using Multi-Test II

Introduction: The medical practice of intervention in allergies actually has broadened its perspective, also focusing on the quality of life of patients. The first step to be instructed to patients, before using pharmacotherapy agents, is to avoid the causal agent.

Objectives: This study aims to analyze the profile of sensitization of patients with allergic complaints and identify possible specific characteristics of each age group and gender.

Materials and Methods: A descriptive cross-sectional study, with data collected from medical records (from Multi-Test^® II database), 1,912 patients underwent skin prick test during period March to October in 2013. Patients were organized and analyzed according to gender, age, and the results of the subtypes tested allergens.

Results: The study was composed of 1,912 patients, 60% male and 40% female, with ages between 3 and 87 years. The positive tests were more prevalent in quantity and intensity, with the mites D. pteronyssinus and D. farinae, each with 60% of the total analyzed. In second place, pollens, especially D. glomerata and F. pratensis.

Conclusion: The female and male genders are also atopic. Fungi and epithelia of dog and cat are also considered potential aeroallergens, but with a not extensive sensitization. Mites have been shown to be frequent in Curitiba, Paraná, followed by pollens with a lower frequency. However, further studies regarding the pollens are needed, since divergences were found about frequency of some species. In addition to that, more studies are necessary in other regions to suit the allergic profile in Brazil.
