ABSTRACT
KEY POINTS: This study examines the impact of dupilumab on medication use for chronic rhinosinusitis with nasal polyposis (CRSwNP) and asthma patients. Patients on dupilumab had a reduction in oral/inhaled/topical steroids, antibiotics, and leukotriene receptor antagonists (LTRAs). The reduction in medication use had no impact on total polyp or SNOT-22 scores.

BACKGROUND: U.S. guidelines recommend that patients with severe asthma be referred to specialists (allergists/immunologists or pulmonologists) for systematic assessment or comanagement; however, contemporary, real-world data on the frequency and impact of specialist care among U.S. severe asthma patients are lacking. OBJECTIVES: To quantify the frequency of asthma specialist visits among U.S. patients with severe asthma, identify patient demographic and clinical characteristics associated with specialist visits and describe health outcomes following specialist care. METHODS: Severe asthma patients aged 6 years or older were identified between January 1, 2015, and December 31, 2017, in the IQVIA PharMetrics® Plus database of commercially insured individuals, based on Healthcare Effectiveness Data and Information Set (HEDIS) criteria and Global Initiative for Asthma (GINA) step 4 or 5 treatment regimens. The frequency of asthma specialist (allergist/immunologist or pulmonologist) visits was described over 2 years. Patient characteristics associated with having 1 or more specialist visits were analyzed using multivariate regressions. Asthma exacerbations and health care resource utilization before and after specialist visit were compared. RESULTS: Of 54,332 patients identified, 38.2% had 1 or more specialist visits over 2 years. Patient characteristics predictive of specialist visits were asthma exacerbation frequency, younger age, and allergy/respiratory comorbidity burden (all P < .001). Among patients with 1 or more specialist visits, a lower prevalence of asthma exacerbations and rescue inhaler use was observed following the first observed specialist visit. CONCLUSIONS: Specialist care was observed in fewer than half of U.S. patients with severe asthma and was least frequent among older adult patients and those with more nonrespiratory comorbidities. Increased specialist involvement in managing severe asthma may help improve care and patient outcomes.

BACKGROUND: It is unknown how active asthma management influences symptom control among inner-city pregnant women who have unique exposures and socioeconomic limitations affecting their care. OBJECTIVE: To assess the impact of an integrated subspecialty intervention composed of education and monitoring on asthma control among underserved women in an antenatal clinic setting. METHODS: We conducted a prospective cohort study of pregnant asthmatic patients participating in a subspecialty clinic integrated into routine prenatal care. We compared baseline characteristics and objective measurements of asthma control between women at an initial visit and those who were evaluated in at least one follow-up. For follow-up, we measured symptom control at successive visits and the incidence of asthma-related complications. RESULTS: Among 85 women enrolled, 53 (62.4%) returned for at least one follow-up visit. Mean baseline Asthma Control Test scores were similarly low (≤19) between groups (one or more follow-up and no follow-up), as were self-administered Asthma Quality of Life Questionnaire scores (<4.7). A total of 72 women had inadequate asthma control resulting in step-up therapy after the initial visit (84.7%). There was a significant increase in ACT scores between the initial and first follow-up visits. For those with an intervening self-administered Asthma Quality of Life Questionnaire, there was also a significant increase by 1.39 ± 0.67 (P = .0003). CONCLUSIONS: We found that uncontrolled asthma is common among urban women seeking routine obstetric care. Our results suggest that even one interventional visit can result in significant improvement in asthma control. Further investigation into mechanisms for optimizing treatment strategies may improve the quality of asthma care during pregnancy in this underserved population.

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.

Asthma is a heterogeneous disease characterized by chronic airway inflammation which has been further elucidated over the last 30 years. This has led to a revolution of pharmacologic targets and the recognition of several biomarkers that have allowed for a more personalized approach to asthma. Up to 20% of asthmatics are considered to be refractory despite adequate maintenance inhaled therapy with frequent exacerbations and poor symptom control Vianello et al. (2019). Newly developed therapies targeting cytokines in the asthma inflammatory pathways have led to reduced exacerbations and improved symptom control and lung function in a subgroup of severe asthmatics. Further upstream targets may provide similar improvement for a broader spectrum of asthmatics.
