Suitable Interpretation of Skin Prick Test and Biomedical Guidance Leads to a Better Clinical State in Atopic Individuals with High Indoor Permanence: Possible Therapeutic Implications

Abstract

Indoor conditions contribute to allergen sensitization and multiple allergens reactivity, mainly for inhaled allergens. This study analyzes if Skin Prick Test (SPT) combined with efficient individual biomedical guidance about allergy development’s social, biological, and environmental aspects can yield a better clinical state with therapeutic implications for atopic individuals with high indoor permanence. We recruited atopic and non-atopic volunteers (clinically and in vitro diagnosed) with indoor permanence above 15 h per day and without previous SPT evaluation. The SPT and serum anti-allergen IgE analyses were performed individually in person, demonstrated, and discussed by the practitioners. Six months after, SPT and specific IgE titers determination were repeated, and a questionnaire to evaluate the effectiveness of the practitioner’s orientation was performed. After six months, 14% of atopic volunteers reported changes in their social habits, 30% said that they avoid the development of allergies clinical symptoms, and 68% reported a substantial improvement in their health after being informed mentored about their allergen reactivity. The control non-atopic group, as expected, reported no changes in social habits, the maintenance of total avoidance of allergic symptoms, and almost no improvement of their health. Reduced SPT and serum allergen-specific IgE titers were detected in the atopic individuals corroborating with questionnaire results. Our results indicated that SPT, followed by an individual and efficient discussion about the main biomedical aspects of allergy development, could exert a pronounced therapeutic role in allergy development by high indoor permanence individuals.
