Analysis of Allergen Detection Results and the Pattern of Allergic Disease Visits in Patients with Suspected Allergic Diseases

Abstract

Objective: With the development of social material civilization, the change of living environment and diet structure, the number of allergic disease visits is increasing gradually. Seeking patient of medical treatment for allergen disease visits is necessary. To analyze the pattern of allergy-related hospital visits and the characteristics of allergen distribution in patients with suspected allergic diseases. Methods: A total of 1584 patients with suspected allergic diseases who underwent allergen testing in the outpatient clinic of the Third Medical Center of Chinese People’s Liberation Army (PLA) General Hospital between January 2018 and December 2020 were enrolled. Serum-specific immunoglobulin E (sIgE) antibodies to multiple allergens and total immunoglobulin E (TIgE) were determined in each patient’s serum using a domestic chemiluminescence instrument. Results: The number of allergic disease visits indicated a bimodal pattern for three consecutive years, with the highest number of visits being between March and May and between August and October. The results of the allergen tests were ranked as follows: Artemisia pollen was the most common seasonal inhalant allergen, dust mites were the most common perennial inhalant allergen, and the three most common food allergens were sea fish/sea crab, milk, and sea shrimp. Conclusions: Based on the distribution characteristics of allergens in this study, most of the allergic disease visits are currently in passive medical mode. It is planned to adjust the patient’s treatment mode to active treatment before the occurrence of allergic symptoms give preventive measures and medication guidance to reduce patients’ allergic symptoms.
