Đặc điểm dị ứng thuốc qua test lẩy da tại Khoa Răng Hàm Mặt, Bệnh viện Bạch Mai 2025 - 2026

Abstract

This retrospective cross-sectional study was conducted to describe the epidemiological characteristics, the distribution of allergic conditions, and drug allergy profiles determined via skin prick testing (SPT) at the Department of Odonto-Stomatology, Bach Mai Hospital, between January 1, 2025, and March 18, 2026. Age, gender, drug classes tested, and pharmacological reactions recorded during SPT served as the primary study variables. Results indicated that among 14,151 patients presenting to the department during the study period, 173 individuals (1.19%) had a clinical history of allergy and were indicated for SPT, with an overall SPT positivity rate of 0.09%. A higher prevalence of allergic history was observed in females compared to males (p < 0.05), and the 18 – 39 age group showed the highest frequency of identified allergies (p < 0.05). Notably, among patients with positive SPT results within the same age group, the positive SPT response was observed in 7.5% of the study population. Females exhibited an allergy risk 0.58 times of males. Within the same gender group, there was no significant difference observed across various age categories, with no statistical significance (p > 0.05).
