Abstract
BACKGROUND: Limited comparative data are available on the impact of systemic corticosteroid (SCS) use in children and adolescents. OBJECTIVE: To determine if asthmatic children and adolescents treated with SCS have a higher likelihood of developing complications versus those not receiving SCS and to examine health care resource utilization (HCRU) in this population. METHODS: A retrospective study of data from children and adolescents with persistent asthma retrieved from the MarketScan database, a large US health claims data set, for the period 2000 to 2017 was performed. Propensity score matching was used to pair patients in the SCS and control cohorts. For complications, SCS subgroups (≥4 or 1-3 annual prescriptions) were compared with asthmatic controls without SCS using logistic regression, and for HCRU, cohorts were compared using negative binomial regression. RESULTS: A total of 67,081 patients were included (SCS: 23,898; control: 43,183). The odds of having a complication were 2.9 (95% confidence interval [CI], 2.5-3.2; P < .001) and 1.6 (95% CI, 1.6-1.7; P < .001) times higher in the ≥4 and 1 to 3 SCS groups, respectively, in the first year of follow-up versus controls. For asthma-related hospitalizations, the incidence rate ratio (IRR) was 6.9 (95% CI, 5.6-8.6) and 3.1 (95% CI, 2.8-3.4) times greater in the ≥4 SCS and 1 to 3 SCS groups, respectively, versus controls; for asthma-related emergency department visits, IRR was 5.0 (95% CI, 4.4-5.6) and 2.9 (95% CI, 2.7-3.0) times greater, respectively, versus controls (all P < .01). CONCLUSION: Children and adolescents receiving SCS for persistent asthma have an increased risk of developing complications and have greater HCRU in the first year of follow-up versus those without SCS exposure.

Abstract
Objective To investigate the clinical and health care burden of chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) in the United States. Study Design Retrospective, cross-sectional design with analyses of patient visits from 2 databases. Setting National Ambulatory Medical Care Survey (NAMCS, 2012-2016) and State Ambulatory Surgery and Services Databases (SASD, 2012-2015) in available states. Methods In each analysis, we identified patients (≥18 years old) with a diagnosis of CRSwNP (ICD-9-CM: 471.x; ICD-10-CM: J33.x) in the visit record during the study period. CRS patients without polyps (CRSsNP: ICD-9-CM: 473.x, ICD-10-CM: J32.x; without CRSwNP codes) were identified for comparison. In the SASD, we focused on visits involving relevant sinus procedures. Outcomes included comorbidities, diagnostic testing, and prescribed medication (NAMCS) and surgery visit characteristics (SASD). Results We identified 2272 NAMCS records from physician offices (183 CRSwNP, 2089 CRSsNP). Most visits were for patients aged <65 years (78.8%, 80.6%) and privately insured (67.7%, 61.5%); CRSwNP visits had a male majority (56.3%, 35.4%). CRSwNP vs CRSsNP visits more often reported asthma (40.2%, 10.3%), allergic rhinitis (14.0%, 8.7%), and congestion (22.0%, 21.1%), with the use of glucocorticoids (21.0%, 17.7%) and nasal allergy medication (26.2%, 10.2%). In the SASD, 427,306 surgery visits were identified (71,195 CRSwNP, 356,111 CRSsNP); demographics were similar to NAMCS. CRSwNP surgeries involved more sinus types (59.3%, 41.4%). Surgeries were mostly elective (>99%) and completed quickly (<2 hours), without perioperative complications (>99%), followed by routine discharge (>91%); follow-up visits were common (14.9%, 13.9%). Conclusion CRSwNP compared to CRSsNP patients have a distinct clinical experience, with moderately higher medication need and more extensive surgery.

Abstract
Background: Although clinical trials documented omalizumab's efficacy in U.S. patients with chronic idiopathic urticaria (CIU), the real-world evidence on its long-term effectiveness is lacking. Objective: To assess omalizumab use and the long-term response in a large sample of U.S. real-world patients. Methods: Patients with CIU and ≥ 12 years old who were initiated on omalizumab (index date) and with ≥ 6 months of postindex data were identified in an electronic medical record system (2007-2018). Omalizumab use was described. Provider assessments of disease control and course, and patient-reported symptoms were compared at 6-month intervals postindex versus baseline in the patients with values available at both time points. Results: A total of 1096 patients (mean age, 44.1 years; 74.7% women) were followed up for a mean of 19 months postindex. Patients, predominantly initiated on a 300-mg dose, received a mean of 15 omalizumab administrations and were treated continuously for a mean of 14.2 months. At 6 months postindex versus baseline, the patients (n = 708) were more likely to be well controlled (odds ratio [OR] 31.68 [95% confidence interval {CI}, 17.20-58.36]) with an improved disease course (OR 15.73 [95% CI, 11.33-21.85]). Moreover, the patients (n = 373) were less likely to report itching (OR 0.39 [95% CI, 0.21-0.76]), rash (OR 0.59 [95% CI, 0.45-0.78]), and swelling (OR 0.46 [95% CI, 0.36-0.59]). Benefits associated with omalizumab treatment were sustained through month 24 and beyond. Conclusion: This real-world study showed that the patients who received a mean of 15 omalizumab administrations over a mean of 14.2 months experienced, starting at 6 and through 24 months after omalizumab initiation and beyond, improved CIU control, course, and symptoms.

Abstract
Objective: To estimate the health-related quality of life (HRQoL) and health utilities among asthma patients with and without comorbid allergies in a managed care population.Methods: This was a retrospective analysis of patient survey responses and pharmacy claims from the Observational Study of Asthma Control and Outcomes (OSACO). Patients ≥12 years-old with persistent asthma received four identical surveys between April-2011 and December-2012. The presence of allergy was identified by a positive response to a survey question about hay fever/seasonal allergies and ≥1 diagnosis-related ICD-9-CM code(s) for allergic conditions. HRQoL instruments included generic utility (EQ-5D-3L [including VAS]), asthma-specific utility (AQL-5D) and asthma-specific health status (Mini Asthma Quality of Life Questionnaire [MiniAQLQ]). Median regression was used for utility scores and Least Squares regression for MiniAQLQ, adjusting for sociodemographic characteristics and smoking.Results: Of the 2681 asthmatics who completed the first survey in the OSACO study, 971 had comorbid allergies. After adjusting for covariates, asthma patients with comorbid allergies had significantly lower MiniAQLQ scores than patients without allergies (-0.489 [95% CI -0.570, -0.409]; p < 0.01), with the greatest decrement/impairment observed for the environmental stimuli domain (-0.729 [95% CI -0.844, -0.613]; p < 0.01). Utility scores were also statistically significantly lower for asthma patients with comorbid allergies compared to those without allergies (EQ-5D, -0.031 [95% CI -0.047, -0.015]; AQL-5D, -0.036 [95% CI -0.042, -0.029]; p < 0.01 each).Conclusions: The presence of allergies with persistent asthma is associated with a significant deleterious impact on several different measures of HRQoL.

Abstract
Background: Approximately two-thirds of people with asthma have some evidence of allergy; their condition differs from nonallergic asthma in terms of predominant symptoms and clinical outcomes. Objective: To compare asthma control and medication use among patients with persistent asthma with evidence of allergy (PA-EA) and patients with persistent asthma with no evidence of allergy (PA-NEA). Methods: A retrospective analysis of survey responses and medication claims data from the Observational Study of Asthma Control and Outcomes study, a prospective survey linked to retrospective claims-based analysis of patients ages ≥ 12 years with persistent asthma in a U.S. health maintenance organization. Evidence of allergy was defined as both a positive response to a survey question about hay fever and/or seasonal allergies and one or more medical diagnostic codes for atopic conditions. Regression models were used to compare asthma control (Asthma Control Questionnaire [ACQ] scores) and asthma medication use between PA-EA and PA-NEA. Results: Adjusted data showed that, versus the patients with PA-NEA (n = 312), patients with PA-EA (n = 971) had higher (worse) 5-item and 6-item ACQ (ACQ-5 and ACQ-6) scores (by 0.34 [95% confidence interval {CI}, 0.24-0.44]; and 0.31 [95% CI, 0.21-0.40], respectively), were more likely to have poorly controlled asthma (ACQ-5 score ≥ 1.5: odds ratio 3.37 [95% CI, 2.07-5.50]; ACQ-6 score ≥ 1.5: odds ratio 3.46 [95% CI, 2.13-5.62]) and less likely to have well-controlled asthma (ACQ-5 score ≤ 0.75: odds ratio 0.21 [95% CI, 0.13-0.34]; ACQ-6 score ≤ 0.75: odds ratio 0.21 [95% CI, 0.13-0.35]). Patients with PA-EA also had greater asthma medication use, most notably 2.5 times more prescriptions of high-dose inhaled corticosteroid in a 4-month period (95% CI, 1.21-5.16) and 16.15 times higher odds of chronic oral corticosteroid use (95% CI, 1.50-174.09) versus PA-NEA. Conclusion: The patients with PA-EA versus PA-NEA had worse asthma control and greater medication use. These patients may need more vigilant clinical oversight and treatment management to ensure adequate asthma control.

Abstract
Objective: To compare healthcare resource utilization (HCRU), healthcare expenditures, and work productivity and activity impairment within a general asthma population with persistent asthma and evidence of allergy (PA-EA) and persistent asthma with no evidence of allergy (PA-NEA).Methods: We conducted a retrospective analysis of survey responses and claims from the Observational Study of Asthma Control and Outcomes (OSACO) study. Eligible patients with persistent asthma aged ≥12 years were sent four surveys over 15 months. Regression models were used to assess the association between: (1) PA-EA (defined as a positive response to a survey question about hay fever/seasonal allergies AND ≥1 diagnostic code for atopic conditions) and HCRU and expenditures; and (2) PA-EA and Work Productivity and Activity Impairment (WPAI)-Asthma questionnaire scores (vs. PA-NEA).Results: Adjusted data showed that, vs. PA-NEA (n = 312), patients with PA-EA (n = 971) incurred 1.34-times more all-cause prescriptions (95% confidence interval [CI], 1.20-1.48), $132.79 higher prescription costs (95% CI, $22.03-243.56), and $926.11 higher all-cause total healthcare costs (95% CI, $279.67-1572.54), per 4-month period. Patients with PA-EA were 4.1% less productive while working (95% CI, 3.75-4.48%) and experienced a 6.5% reduction in all activities (95% CI, 6.11-6.88%) vs. those with PA-NEA.Conclusions: Patients with PA-EA had greater HCRU, healthcare expenditures, and lower productivity compared with those patients with PA-NEA. These results highlight the burden of atopy in patients with persistent asthma and underscore the importance of allergic endotype identification for more vigilant disease management.

Abstract
Administration in complete Freund's adjuvant of encephalitogenic protein (EP), derived from central nervous tissue to guinea pigs, regularly results in the development of experimental allergic encephalitis (EAE) which leads to the death of the animals. Administration of EP in incomplete Freund's adjuvant at an appropriate time will completely suppress the clinical development of disease. Results reported herein show that animals receiving suppressive injections of EP for 7 days show depression of lymphocyte DNA synthesis and macrophage migration inhibition, but not of skin reactivity, in response to EP immediately following the injections, and subsequently show recovery of lymphocyte reactivity but do not develop clinical manifestations of EAE. Humoral or other factors may prevent the development of disease in these animals. Guinea pigs receiving injections of EP for 14 days show profound and prolonged depression of lymphocyte reactivity to EP and macrophage migration inhibition. Possible mechanisms for these results include a diminished number or function of reactive cells or activity of a population of cells with the capacity to suppress cellular immune responses. Nonspecific suppression of reactivity to an unrelated antigen during the suppressive injections was not observed.
