Objective To analyze the effect of benralizumab in severe eosinophilic asthma (SA) and chronic rhinosinusitis with polyps (CRSwP). Methods Retrospective review of patients with both SA and CRSwP that were treated with benralizumab. Asthma controlled test (ACT), pulmonary function metrics (FEV1), Meltzer endoscopic polyp scores, SNOT-22 scores, were collected before and after at least 4 months of benralizumab therapy. Results 23 patients were included. The mean age at the time of enrollment into benralizumab therapy was 50.47 ± 17.3 years and majority (65.2%, n = 15) were males. Pulmonary Effects: In comparison to baseline ACT, scores at four months showed significant improvement (p = 0.03). In those with pre and post spirometry measurements, mean FEV1 showed significant increase following benralizumab therapy (p = 0.04) with a mean increase of 547 mL ± 597 mL following therapy. Sinonasal Effects: 78.5% of subjects on benralizumab had a significant improvement in sinonasal symptoms (p = 0.009) based on their SNOT-22 scores. Additionally, there was an improvement in endoscopic polyp scores, although not statistically significant, following benralizumab therapy (p = 0.2) with 54.5% patients showing improvement. Conclusion Usage of benralizumab in patients with SA and CRSwNP can lead to significantly improved asthma control, lung function, and sinonasal quality of life. Additionally, in this patient population, there was a subset of patients that showed a significant reduction in polyp burden.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
