[Compliance and withdraw reason of sublingual immunotherapy in 245 patients with allergic rhinitis].

Abstract

Objective:To investigate the compliance of patients with allergic rhinitis（AR） receiving sublingual immunotherapy and its influencing factors. Methods:The clinical data of 291 AR patients who received sublingual immunotherapy for dust mites at the First Hospital of Peking University from January 2016 to January 2018 were retrospectively analyzed, and their outpatient or telephone follow-up was conducted. For patients whose treatment time was less than 2 years, the time and reason for the loss were recorded, and the factors affecting their compliance were discussed from the aspects of gender, age, and education. Results:Among the 291 patients, 245 cases（84.2%） were successfully followed up, and 193 cases（78.8%） fell off midway（treatment time<2 years）. The overall compliance rate was 21.22%（52/245）. The compliance rate of children is higher than that of adults（χ²=21.306, P<0.05）, and gender and education level have no significant effect on the compliance rate. The time period for the largest number of shedding was 6-<12 months after treatment（68 cases, 27.8%）. The main cause of shedding was symptom relief, which was considered cured（16.7%）. Secondly, within 3 months after treatment, a total of 61 patients（24.9%） fell off, of which 34 cases（13.9%） fell off because of troublesome medication, often missed medication, and simply stopped taking the drug. Statistics on the overall reasons for shedding in 193 patients, the top three shedding reasons were: cured after symptom relief（59 cases, 30.6%）, troublesome medication, discontinuation after missed dose（44 cases, 22.8%）, slow onset or ineffectiveness（26 cases, 13.5%）. Conclusion:The overall compliance of sublingual immunotherapy in patients with allergic rhinitis is poor, and the compliance of children is better than that of adults. Clinicians should focus on the reasons for patients to fall off at various times, strengthen patient education, enhance patient confidence in treatment, and improve the compliance of patients.
