ABSTRACT
Introduction: Aging causes the immune system to undergo significant changes, a phenomenon called immunosenescence. However, studies in aged adults are few and no strong conclusions exist as to whether atopy, determined by positive skin tests, decreases with age or does not.Objective: To assess skin sensitivity to mites in aged patients with allergic respiratory disease.
Methods: A case-control study was carried out, between January 2018 and January 2019, with aged patients diagnosed with allergic respiratory disease, all from the protocolized allergy consultations of Hermanos Ameijeiras Clinical-Surgical Hospital. The study population consisted of 60 patients divided into two groups: group A, aged over 60 years old; and group B, aged 18-40 years old. For statistical processing, the variables were compared using the chi-square and Student's t tests.
Results: In both groups, the female sex predominated. The mean age of group A was 67.5±5.6 years. Mild perennial allergic rhinitis (30.0%) and mild persistent asthma (30.0%) were the most frequent diagnoses in group B, while moderate persistent asthma (30.0%) was in group A. In group A, the sensitization profile was described concerning Blomia tropicalis (26.7%), Dermatophagoides Pteronyssinus (23.3%), and Dermatophagoides Siboney (20%); while in group B, the sensitization profile is considered as significantly higher, accounting for 60%, 43.3% and 36.7%, respectively. Regarding histamine values, the characteristics between groups was the same, accounting for 4.5 mm in group A compared to 5.8 mm in group B.
Conclusions: Skin sensitivity to mites in aged patients with allergic respiratory disease was lower than that found in younger patients.
