摘要

Abstract Background Moderate‐to‐severe allergic rhinitis ( AR ) may increase the risk of developing or worsening asthma, whereas treatment of AR with subcutaneously or sublingual allergen immunotherapy ( SLIT ) may slow this progression. Methods In a retrospective real‐world analysis, prescription fulfilment data were gathered from French retail pharmacies between 1 March 2012 and 31 December 2016. Using linear regression analyses, patients having received at least two prescriptions of grass pollen SLIT tablets over at least 2 successive years were compared with control patients having received symptomatic medications only. Results A total of 1099 SLIT patients and 27?475 control patients were included in the main analysis. With regard to symptomatic AR medication dispensing, we observed a 50% decrease in the pre‐index/follow‐up ratio in the SLIT group, a 30% increase in the control group without age matching ( P ??0.0001 vs SLIT ) and a 20% increase in the control group with age matching ( P ??0.0001 vs SLIT ). During the follow‐up, 11 (1.8%) and 782 (5.3%) patients initiated asthma treatment in the SLIT and control groups, respectively. The relative risk of medication dispensing for new asthma was lower in the SLIT group (by 62.5% [29.1%‐80.1%] without age matching ( P ?=?0.0025) and by 63.7% [31.5%‐80.7%] with age matching; P ?=?0.0018). SLIT was also associated with slower progression of asthma medication dispensing during the follow‐up period, relative to the control group (regression coefficient: ?0.58 [?0.74 to 0.42] without age matching ( P ??0.0001) and ?0.61 [?0.76 to ?0.46] with age matching; P ??0.0001). Conclusion Prescription of grass pollen SLIT tablets reduced the dispensing of AR and asthma medications in real life.
