Abstract
Objective: To evaluate the efficacy of subcutaneous specific immunotherapy (SCIT) for allergic rhinitis (AR) combined with asthma.
Methods: A retrospective analysis of clinical data from 93 patients with AR combined with asthma admitted to our hospital from January 2022 to January 2023 was conducted. Based on the treatment interventions received, the patients were divided into a control group (n=46, receiving sublingual specific immunotherapy [SLIT]) and an observation group (n=47, receiving SCIT). Clinical treatment response, lung function, levels of immune indicators, levels of inflammatory indicators, and occurrence of adverse reactions were compared between the two groups.
Results: The total response rate was 95.74% in the observation group and 84.78% in the control group (P > 0.05). In terms of scores for symptom assessment, Total Nasal Symptom Score (TNSS), Depression Anxiety Stress Scale (DASS), and Nasal Allergy Symptom Score (NASS) scores in both groups decreased after treatment, with greater decreases in the observation group (P < 0.05). In addition, lung function was improved in both groups after treatment as reflected by increased Forced Expiratory Volume in one second to Forced Vital Capacity ratio (FEV1/FVC) and Peak Expiratory Flow (PEF) levels, with greater increases found in the observation group (P < 0.05). Among the immune and inflammatory indicators, Cluster of Differentiation 14 (CD14) and Interleukin-33 (IL-33) levels decreased, while Secretory Protein D-1 (SPD-1), serum Immunoglobulin G4 (sIgG4), Interferon-γ (INF-γ), and Interleukin-27 (IL-27) levels increased in both groups after treatment, with greater changes observed in the observation group (P < 0.05). There was no significant difference in the incidence of adverse reactions between the observation group (14.89%) and the control group (21.74%) (P > 0.05).
Conclusion: In the treatment of AR combined with asthma, SCIT can better alleviate clinical symptoms, improve lung function, regulate immune and inflammatory responses in patients, and does not increase the risk of adverse reactions compared to SLIT.
