RESUMEN
Background: Aspirin exacerbated respiratory disease (AERD) is an inflammatory condition that consists of eosinophilic asthma, chronic rhinosinusitis with nasal polyps, and respiratory reactions to cyclooxygenase-1 inhibitors. Aspirin therapy after aspirin desensitization (ATAD) is the most extensively studied treatment paradigm for AERD. Objective: The objective was to identify which time point of ATAD was most predictive of long-term outcomes as measured by the 22-item Sino-Nasal Outcome Test (SNOT-22). Methods: A retrospective chart review was conducted of patients at a single institution who underwent endoscopic sinus surgery, followed by ATAD, and had remained on ATAD for 2 consecutive years. SNOT-22 scores were recorded at predesensitization as well as at the 3-, 6-, 12-, and 24-month postdesensitization time points. The patients were separated into two cohorts at each of the data collection time points based on whether their SNOT-22 scores were < 20 (responders) or ≥ 20 (nonresponders). Responder status was compared between each time point and at 24-month postdesensitization. The odds ratios (OR) were then calculated between the two groups at each of the following time points: postsurgery/predesensitization, and 3-, 6-, and 12-month postdesensitization. Results: There were 70 patients who met the inclusion criteria of having 24-month postdesensitization SNOT-22 scores available. Responder status at 6 months after surgery had the most predictive OR 16.5 (95% confidence interval, 3.71-73.44) for long-term outcomes at 24 months. Conclusion: The SNOT-22 scores after 6 months of ATAD showed the greatest predictive value for long-term quality-of-life outcomes and, therefore, poor 6-month SNOT-22 scores could serve as a basis for consideration of alternative therapies.

Aspirin-exacerbated respiratory disease (AERD) is characterized by the clinical triad of chronic rhinosinusitis with nasal polyps, asthma, and an intolerance to medications that inhibit the cycloxgenase-1 enzyme. Patients with AERD on average have more severe respiratory disease compared with patients with chronic rhinosinusitis with nasal polyps and/or asthma alone. Although patients with AERD traditionally develop significant upper and lower respiratory tract symptoms on ingestion of cycloxgenase-1 inhibitors, most of these same patients report clinical benefit when desensitized to aspirin and maintained on daily aspirin therapy. This Work Group Report provides a comprehensive review of aspirin challenges, aspirin desensitizations, and maintenance aspirin therapy in patients with AERD. Identification of appropriate candidates, indications and contraindications, medical and surgical optimization strategies, protocols, medical management during the desensitization, and recommendations for maintenance aspirin therapy following desensitization are reviewed. Also included is a summary of studies evaluating the clinical efficacy of aspirin therapy after desensitization as well as a discussion on the possible cellular and molecular mechanisms explaining how this therapy provides unique benefit to patients with AERD.

Background: Only a fraction of patients with allergic rhinitis receive allergen-specific immunotherapy (AIT). AIT is most commonly delivered subcutaneously in a series of injections over 3-5 years. Common obstacles to completing this therapy include cost and inconvenience. Intralymphatic immunotherapy (ILIT) has been proposed as a faster alternative, which requires as few as three injections spaced 4 weeks apart. Objective: This systematic review and meta-analysis evaluated the current evidence that supports the use of ILIT for allergic rhinitis. Methods: Clinical trials were identified in the published literature by using an electronic search strategy and were evaluated by using a risk of bias tool. Treatment outcome (symptom scores, medication scores, and combined symptom and medication scores) and provocation testing results (nasal provocation and skin-prick testing) were included in a meta-analysis of standardized mean difference with subgrouping by using a random-effects model. Overall adverse event rates were tabulated, and overall risk ratios were calculated by using a random-effects model. Results: We identified 17 clinical trials that met eligibility criteria. The standardized mean difference of ILIT on the symptom and medication score was -0.72 (95% confidence interval [CI], -0.98 to -0.46; p < 0.0001) (n = 10). The standardized mean difference of ILIT on nasal provocation and skin-prick testing was -1.00 (95% CI, -1.38 to -0.61; p < 0.0001) (n = 7) and -0.73 (95% CI, -0.99 to -0.47; p < 0.0001) (n = 7), respectively. No statistically significant heterogeneity was detected. The overall adverse event rate was 39.5% for ILIT and 23.5% for placebo. Also, 98.4% of adverse events were mild. Conclusion: Our meta-analysis demonstrated that ILIT was safe, conferred desensitization to seasonal and nonseasonal allergens, alleviated allergic rhinitis symptoms, and reduced medication use. A larger randomized, double-blind, placebo controlled trial will be necessary for wider adaptation of this form of AIT.

Background: Aspirin therapy and/or type 2 (T2) biologics are used in the management of aspirin-exacerbated respiratory disease (AERD). Objective: To identify the number of patients with AERD who tolerated aspirin therapy, yet due to persistent symptoms, incorporated T2 biologic management. Methods: A retrospective review was performed between July 2016 and June 2019. Patients with AERD and who underwent endoscopic sinus surgery (ESS), aspirin desensitization (AD), and at least 6 months of aspirin therapy (ATAD) after AD, and who remained biologic-naive up through this timepoint were included in the study. Introduction of a T2 biologic while on ATAD was the primary outcome. The secondary outcome was a change in a validated patient-reported outcome measure for chronic rhinosinusitis score between the postoperative predesensitization timepoint, and the 6-month postdesensitization timepoint, presented as means and compared by using the Student's t-test. Results: A total of 103 patients met inclusion criteria. Two patients (1.9%) ultimately supplemented ATAD with a T2 biologic. The mean outcomes measure test score after 6 months of ATAD for patients who received biologics was 40.5 versus 15 in those who did not receive biologics (p = 0.02). The mean differences between the postoperative predesensitization test score and the 6-month postdesensitization test score for patients who went on to receive biologics was an increase of 13 versus a decrease of 10 for those patients who did not receive biologics (p = 0.12). Conclusion: ESS, coupled with AD and ATAD, was successful in the long-term management of the majority of the patients with AERD, which rarely required the incorporation of T2 biologics. Patient questionnaires, such as outcomes measure test score, may identify aspirin therapy failures and help guide the practitioner in deciding when to introduce T2 biologics into the patient's treatment regimen.

PURPOSE: This study evaluated whether stratified preoperative, pre- aspirin desensitization (AD) sinonasal symptom scores predict postoperative, post-AD outcomes in Aspirin exacerbated respiratory disease (AERD). MATERIALS AND METHODS: Retrospective chart review of patients with aspirin challenge-proven AERD who underwent endoscopic sinus surgery followed by AD was performed. Preoperative, postoperative/pre-AD, and postoperative/post-AD sinonasal symptom scores were collected (22-item Sino-Nasal Outcomes Test, SNOT-22). A longitudinal linear mixed-effects model was used for data analysis. RESULTS: Forty-seven patients (59.6% female) aged 48.0 ± 13.2 were included. Average time from surgery to AD was 70.0 ± 52.8 days. Preoperative SNOT-22 scores (n = 47) were divided into tertiles (cutoffs of 36 and 54 indicating mild [22.5 ± 13.7], moderate [44.3 ± 12.2], and severe [72.9 ± 19.7] disease). This corresponded to 12 (25.5%), 18 (38.3%), and 17 (36.2%) subjects being categorized into mild, moderate, and severe tertiles, respectively. Postoperative, pre-AD SNOT-22 in all disease groups decreased and were not significantly different (12.3 ± 13.7, 11.1 ± 12.2, 22.7 ± 19.7; p = 0.074). At short-term post-AD, only the severe group worsened (35.0 ± 20.3, p < 0.001), whereas other groups demonstrated negligible change (9.3 ± 14.3 and 14.4 ± 12.2). At long-term post-AD, all groups redemonstrated convergence in symptom scores (23.7 ± 20.9, 19.4 ± 15.4, and 31.0 ± 27.6, p = 0.304). CONCLUSION: Preoperative SNOT-22 scores may be used as a predictor of postoperative, post-AD patient-reported outcomes in AERD. Patients with mild and moderate disease may derive benefit from surgery and AD alone, while those with severe disease may require additional interventions (e.g., biologics).

BACKGROUND: Patients with chronic rhinosinusitis with nasal polyps (CRSwNP) generally have a high symptom burden and poor health-related quality of life, often requiring recurring systemic corticosteroid use and repeated sinus surgery. Dupilumab is a fully human monoclonal antibody that inhibits signalling of interleukin (IL)-4 and IL-13, key drivers of type 2 inflammation, and has been approved for use in atopic dermatitis and asthma. In these two studies, we aimed to assess efficacy and safety of dupilumab in patients with CRSwNP despite previous treatment with systemic corticosteroids, surgery, or both. METHODS: LIBERTY NP SINUS-24 and LIBERTY NP SINUS-52 were two multinational, multicentre, randomised, double-blind, placebo-controlled, parallel-group studies assessing dupilumab added to standard of care in adults with severe CRSwNP. SINUS-24 was done in 67 centres in 13 countries, and SINUS-52 was done in 117 centres in 14 countries. Eligible patients were 18 years or older with bilateral CRSwNP and symptoms despite intranasal corticosteroid use, receiving systemic corticosteroids in the preceding 2 years, or having had sinonasal surgery. Patients in SINUS-24 were randomly assigned (1:1) to subcutaneous dupilumab 300 mg or placebo every 2 weeks for 24 weeks. Patients in SINUS-52 were randomly assigned (1:1:1) to dupilumab 300 mg every 2 weeks for 52 weeks, dupilumab every 2 weeks for 24 weeks and then every 4 weeks for the remaining 28 weeks, or placebo every 2 weeks for 52 weeks. All patients were randomly assigned centrally with a permuted block randomisation schedule. Randomisation was stratified by asthma or non-steroidal anti-inflammatory drug-exacerbated respiratory disease status at screening, previous surgery at screening, and country. Patients with or without comorbid asthma were included. Coprimary endpoints were changes from baseline to week 24 in nasal polyp score (NPS), nasal congestion or obstruction, and sinus Lund-Mackay CT scores (a coprimary endpoint in Japan), done in an intention-to-treat population. Safety was assessed in a pooled population of both dupilumab groups in SINUS-52 up to week 24 and the dupilumab group in SINUS-24 and the placebo groups in both studies until week 24. The trials are complete and registered at ClinicalTrials.gov, NCT02912468 and NCT02898454. FINDINGS: Between Dec 5, 2016, and Aug 3, 2017, 276 patients were enrolled in SINUS-24, with 143 in the dupilumab group and 133 in the placebo group receiving at least one study drug dose. Between Nov 28, 2016, and Aug 28, 2017, 448 patients were enrolled in SINUS-52, with 150 receiving at least one dose of dupilumab every 2 weeks, 145 receiving at least one dose of dupilumab every 2 weeks for 24 weeks and every 4 weeks until week 52, and 153 receiving at least one dose of placebo. Dupilumab significantly improved the coprimary endpoints in both studies. At 24 weeks, least squares mean difference in NPS of dupilumab treatment versus placebo was -2·06 (95% CI -2·43 to -1·69; p<0·0001) in SINUS-24 and -1·80 (-2·10 to -1·51; p<0·0001) in SINUS-52; difference in nasal congestion or obstruction score was -0·89 (-1·07 to -0·71; p<0·0001) in SINUS-24 and -0·87 (-1·03 to -0·71; p<0·0001) in SINUS-52; and difference in Lund-Mackay CT scores was -7·44 (-8·35 to -6·53; p<0·0001) in SINUS-24 and -5·13 (-5·80 to -4·46; p<0·0001) in SINUS-52. The most common adverse events (nasopharyngitis, worsening of nasal polyps and asthma, headache, epistaxis, and injection-site erythema) were more frequent with placebo. INTERPRETATION: In adult patients with severe CRSwNP, dupilumab reduced polyp size, sinus opacification, and severity of symptoms and was well tolerated. These results support the benefits of adding dupilumab to daily standard of care for patients with severe CRSwNP who otherwise have few therapeutic options.

There is currently interest regarding CRSsNP patients with refractory symptomatology following functional endoscopic sinus surgery, and which of these patients can derive benefit from low-dose macrolide therapy. In the present study, we analyze a cohort of over fifty CRSsNP patients on macrolide therapy; structured histopathological findings at the time of surgery were analyzed against the success of macrolide treatment. Independently, fibrosis, absence of squamous metaplasia, absence of eosinophilia, presence of neutrophilic infiltrate, and lymphoplasmocytic predominance were all associated with objective success of macrolide treatment; these findings may allow clinicians to more appropriately select patients for this therapy.

Aspirin desensitization is a treatment option for patients with aspirin-exacerbated respiratory disease (AERD). Some patients with an excellent history of aspirin or nonsteroidal anti-inflammatory drug (NSAID) reactions have negative aspirin challenges/desensitization. This study discusses the clinical entity of silent desensitization in AERD and the dilemma that this presents to the practicing allergist/immunologist. We discuss a series of patients with a strong history of NSAID reactions who initially underwent a negative challenge/silent desensitization. These patients were subsequently proven to have AERD after a second positive aspirin challenge. Silent desensitization is an uncommon but important outcome to recognize in AERD. Clinicians performing aspirin desensitization should understand that this can occur and consider a second confirmatory aspirin challenge in some patients.

BACKGROUND: Succinate, although most famous for its role in the Krebs cycle, can be released extracellularly as a signal of cellular distress, particularly in situations of metabolic stress and inflammation. Solitary chemosensory cells (SCCs) express SUCNR1, the succinate receptor, and modulate type 2 inflammatory responses in helminth and protozoal infections in the small intestine. SCCs are the dominant epithelial source of interleukin-25, as well as an important source of cysteinyl leukotrienes in the airway, and have been implicated as upstream agents in type 2 inflammation in chronic rhinosinusitis (CRS) and asthma. METHODS: In this study, we used scRNAseq analysis, live cell imaging of intracellular calcium from primary sinonasal air-liquid interface (ALI) cultures from 1 donor, and measure antimicrobial peptide release from 5 donors to demonstrate preliminary evidence suggesting that succinate can act as a stimulant of SCCs in the human sinonasal epithelium. RESULTS: Results from scRNAseq analysis show that approximately 10% of the SCC/ionocyte cluster of cells expressed SUCNR1 as well as a small population of immune cells. Using live cell imaging of intracellular calcium, we also demonstrate that clusters of cells on primary sinonasal ALI cultures initiated calcium-mediated signaling in response to succinate stimulation. Furthermore, we present evidence that primary sinonasal ALI cultures treated with succinate had increased levels of apical beta-defensin 2, an antimicrobial peptide, compared to treatment with a control solution. CONCLUSION: Overall, these findings demonstrate the need for further investigation into the activation of the sinonasal epithelium by succinate in the pathogenesis of CRS.

BACKGROUND: Patients with aspirin-exacerbated respiratory disease (AERD) are among the most challenging rhinologic patients to treat. AERD has a complex inflammatory milieu of lipid mediators and cytokines. In this study we evaluated cytokine differences in the complex AERD environment at the mucus, epithelial, and tissue levels. METHODS: Samples were acquired at the time of sinus surgery from 21 patients (seven steroid-treated, 14 untreated) with aspirin challenge-confirmed AERD. Three methods (sponge adsorption, epithelial brushing, tissue biopsy) were used to acquire samples from the respective sinus sampling sites (mucus, polyp epithelium, and full-thickness polyp) of each patient. We measured and compared 16 cytokine concentrations in AERD patients with or without prednisone treatment using the Luminex platform. RESULTS: In most sampling sites, IL-5, IL-6, IL-10, IL-13, IL-33, CCL20, and TNF-α were detected at higher concentrations than IFN-γ, IL-1ß, IL-17A, IL-4, IL-22, IL-17E/IL25, and GM-CSF. Each sampling site had a different pattern of cytokine levels, and except for IL-5 and IL-25 there was no correlation among sampling methods for each cytokine tested. The most notable and significant decreases in cytokines from those treated with prednisone were observed in the epithelium for IL-5, IL-10, IL-33, and IFN-γ. CONCLUSIONS: In the epithelial samples, type 2-associated cytokines IL-5 and IL-33, the anti-inflammatory cytokine IL-10, and IFN-γ were lower in AERD patients treated with prednisone. This work serves as a basis to assess therapeutic-induced mucosal cytokine responses in AERD and indicates that the site of cytokine measurement is an important consideration when assessing results.

BACKGROUND: Solitary chemosensory cells (SCCs) in the murine nasal epithelium are discrete specialized cells that respond to irritants and activate trigeminal nerve fibers through the release of acetylcholine (ACh), resulting in local neurogenic inflammation. In addition to releasing ACh, SCCs are the exclusive epithelial source of interleukin (IL)-25. In humans, SCCs are significantly expanded in sinonasal polyps (NPs). However, the SCC-trigeminal synapse has yet to be demonstrated in human sinonasal epithelium. METHODS: Immunofluorescence for trigeminal nerve fiber markers, nicotinic ACh receptors (nChR), and SCC markers was performed in vibratome sections from polyp and healthy turbinate tissue. Quantitative polymerase chain reaction and immunofluorescence of cultured epithelial cells were used to evaluate the expansion of SCCs. Last, intracellular calcium imaging was used to demonstrate cholinergic signaling in sinonasal epithelial cells. RESULTS: Calcitonin gene-related peptide (CGRP) immunostaining was used to identify cholinergic nerve endings, which were only evident in sections from the inferior turbinate and intertwined with SCCs (α-gustducin-positive cells). CGRP-positive nerve endings were not identified in sections from NPs. Human SCCs expressed nChR as well as the ACh synthetic enzyme choline acetyltransferase. Live cell calcium imaging demonstrated functionally active cholinergic signaling in discrete sinonasal epithelial cells, consistent with SCCs. Finally, SCC-specific genes were dramatically upregulated with pretreatment with IL-13 and nicotinic agonists. CONCLUSION: SCCs are innervated by trigeminal nerve endings in healthy turbinate tissue but not in NPs. SCCs express ACh receptors as well as choline acetyltransferase and, in the setting of a type 2 inflammatory environment, denervated SCCs dramatically expand with nicotinic stimulation.

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) is optimally managed by endoscopic sinus surgery (ESS) followed by aspirin therapy after desensitization (ATAD). Most AERD quality of life (QOL) studies use the 22-item Sinonasal Outcomes Test (SNOT-22), which focuses predominantly on sinonasal outcomes. OBJECTIVE: This study seeks to assess QOL outcomes in AERD patients after ESS and ATAD via the 12-item Short Form Survey (SF-12), a well-validated QOL measure for general health status of chronic conditions. METHODS: Retrospective review of 112 AERD patients who underwent ESS followed by ATAD at our institution between 2016 and 2019. SF-12 was collected preoperatively, postoperatively/pre-AD, and serially post-AD (1-3, 4-6, 7-12, and >12 months). Optum® PRO CoRE software was used to compare data to national norms. ANOVA was performed comparing physical component summary (PCS), mental component summary (MCS) and eight health domains (physical functioning, role physical, general health, bodily pain, vitality, social functioning, role emotional, and mental health). RESULTS: AERD patients showed improvement in PCS scores across all timepoints after ESS and ATAD (p = 0.004). When stratified by gender, women demonstrated an improvement in PCS scores (p = 0.004). Within the domains, there were significant improvements in social functioning (SF), role physical (RP), and bodily pain (BP) at all timepoints (SF: p = 0.006; RP: p = 0.005; BP: p < 0.001). CONCLUSIONS: AERD patients undergoing ESS and ATAD show improvement in physical QOL and 3 of the 8 health domains as measured by the SF-12. Future studies can use the SF-12 to study the impact of AERD treatment versus other chronic diseases and health demographics.

BACKGROUND: Treatment of aspirin-exacerbated respiratory disease (AERD) includes endoscopic sinus surgery (ESS) and aspirin desensitization (AD) with aspirin therapy after desensitization (ATAD). The objective of this study was to determine the rate of major complications associated with aspirin use that resulted in the discontinuation of aspirin therapy. METHODS: This study was a retrospective chart review of patients with AERD who underwent ESS, AD, and ATAD at a single AERD tertiary center between July 2016 and February 2019. Complications associated with aspirin that resulted in the discontinuation of aspirin therapy were analyzed via analysis of variance and logistic regression. RESULTS: In total, 109 AERD patients underwent ESS with subsequent AD. Ten patients (9.2%) discontinued therapy after AD, before starting ATAD. Eight patients (7.3%) discontinued therapy after starting ATAD. There were 91 patients (83.5%) with no complications throughout ATAD. Reasons for discontinuation included gastritis, upper gastrointestinal (GI) bleed, anaphylaxis, persistent sinonasal symptoms, recurrent epistaxis, asthma exacerbation, and a nummular rash. There was no significant correlation between complication rate and (1) aspirin doses (analysis of variance [ANOVA] F: 0.69; p = 0.51), (2) gender (odds ratio [OR] 0.56; 95% confidence interval [CI], 0.19 to 1.65; p = 0.30), (3) age (OR 1.04; 95% CI, 0.96 to 1.09; p = 0.06), or (4) race/ethnicity (OR 1.12; 95% CI, 0.88 to 1.44; p = 0.36). CONCLUSION: AD with ATAD was associated with only a 0.92% incidence of a clinically significant GI bleed, and only a 0.92% incidence of anaphylaxis. A remaining 16 patients (14.7%) discontinued aspirin therapy due to minor clinical sequelae. These findings demonstrate that the majority of AERD patients tolerate AD with ATAD without any major complications.

BACKGROUND: Chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP), and aspirin-exacerbated respiratory disease (AERD) have varying levels of inflammation and disease severity. Solitary chemosensory cells (SCCs) are enriched in nasal polyps, are the primary source of interleukin 25 (IL-25) in upper airways, leading to type 2 inflammation, and are activated by bitter-tasting denatonium benzoate (DB). Thus, we sought to evaluate DB taste perception at a range of concentrations in order to identify 1 that most differentiates CRS subgroups from controls. METHODS: CRSsNP (n = 25), CRSwNP (n = 26), and AERD (n = 27) patients as well as controls (n = 25) tasted 6 DB concentrations in a fixed, random order, rating on a category scale of 0 (no intensity) to 12 (extremely intense). Sinonasal epithelial cultures were treated with and without denatonium and analyzed for IL-25 via flow cytometry. RESULTS: CRSsNP patients rated DB as significantly less intense than did controls at all concentrations: 5.62 × 10-9 M, 1.00 × 10-8 M, 1.78 × 10-8 M, 3.16 × 10-8 M, 5.62 × 10-8 M, and 1.00 × 10-7 M (all p < 0.0083). CRSwNP patients did not show significant differences from controls. AERD patients rated DB as significantly more intense than did controls at concentrations of 1.00 × 10-8 M and 3.16 × 10-8 M (p < 0.0083). In vitro data demonstrated significant increase in IL-25-positive cells after denatonium stimulation (n = 5), compared to control (n = 5) (p = 0.012). CONCLUSION: Our findings link in vitro DB stimulation of sinonasal tissue with increased IL-25 and show differential DB taste perception in CRS subgroups relative to the control group, with CRSsNP being hyposensitive and AERD being hypersensitive. We propose a concentration of 3.16 × 10-8 M for future study of clinical utility.

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) is an aggressive respiratory tract inflammatory disorder manifesting as asthma, chronic rhinosinusitis with nasal polyposis, and a respiratory sensitivity to aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). Corticosteroids, both systemic and topical/inhaled, are used to treat inflammation of the upper and lower airways. Our objective was to examine the potential impact of complete endoscopic sinus surgery (ESS) and aspirin desensitization (AD) on short-term and long-term corticosteroid use. METHODS: For this pilot study, a retrospective chart review of all patients with AERD who underwent ESS followed by AD was performed. Daily prednisone use, average daily prednisone dose, and inhaled corticosteroid use were analyzed at the following time points: preoperative, postoperative/pre-AD, and 2 to 3 months, 4 to 6 months, 7 to 12 months, and 13 to 24 months following AD. RESULTS: A total of 125 patients underwent ESS followed by AD. Compared to preoperatively, patients who underwent ESS and AD were less likely to be on daily prednisone at all time points and upon long-term follow-up (32% preoperatively vs 10% at 13 to 24 months, McNemar's test = 9.00, p = 0.009). Average daily prednisone dose decreased from 10.6 ± 7.9 mg preoperatively to 3.8 ± 2.6 mg at 13 to 24 months following AD (Mann-Whitney U; W = 122, p = 0.01). Similarly, high-dose and medium-dose inhaled corticosteroid use decreased from 18% to 7% and from 36% to 22% respectively (Pearson's chi-square = 8.06, p = 0.05). CONCLUSION: In our AERD cohort who underwent ESS followed by AD, there was an observed decrease in overall systemic and topical/inhaled corticosteroid use. These findings can have implications for treatment given the potentially hazardous side effects of corticosteroid use.
