Abstract
INTRODUCTION Up-to-date systematic reviews (SRs) are essential for making evidence-based decisions. During the 2019 coronavirus (COVID-19) pandemic, there was a particular need for up-to-date evidence, making the living systematic review (LSR) approach an appropriate review type. However, this approach poses certain challenges. OBJECTIVE AND OUTLINE We aim to provide practice insights and report challenges that we faced while conducting two Cochrane LSRs on COVID-19 treatments with (i) convalescent plasma and (ii) systemic corticosteroids. We address our objective with an experience report and share challenges of the following components based on Iannizzi et al. (2022): study design, publication types, intervention/comparator, outcomes, search strategy, review updates and transparent reporting of differences between review updates. RESULTS Regarding the study design, the plasma LSR included different study designs because RCT data were not available at the beginning of the pandemic, whereas for the corticosteroids LSR, which started several months later, RCT data were already available. The challenges in both LSRs included the publication types (preprints were included with caution) and the intervention/comparator, for instance the unavailability of standard of care for either LSR, or SARS-CoV-2 variants occurrence. Further challenges in both LSRs occurred in the components "outcome sets" (which had to be adjusted) and "literature search". The decision criteria for updating were based on important studies and available resources in both LSRs and policy relevance in the plasma LSR. Transparent reporting of the differences between the various update versions were discussed for both LSRs. DISCUSSION AND CONCLUSION In summary, there are similarities and differences regarding challenges of review components for both LSRs. It is important to keep in mind that the two LSR examples presented here were conducted in the wake of the COVID-19 pandemic. Therefore, many of the challenges are attributable to the pandemic and are not specific to LSRs, such as constant adjustments of the outcome sets or changes in the database search. Nevertheless, we believe that some of these aspects are helpful for LSR authors and are applicable to other LSRs outside the pandemic context, particularly in areas where new evidence is rapidly emerging.

Abstract
BACKGROUND Idiopathic chronic eosinophilic pneumonia (ICEP) is a rare disease characterized by pulmonary radiological alterations, peripheral eosinophilia, and demonstrated pulmonary eosinophilia. Oral steroids (OSs) are the standard management, but relapses occur in up to 50% of patients during the decrease or suspension of steroids, usually requiring reinitiation of treatment, exposing patients to secondary events derived from the management. Management with monoclonal antibodies has been proposed in these cases to control the disease and limit the secondary effects. The objective is to describe the extent and type of evidence regarding the use of monoclonal antibodies for ICEP. METHODS A panoramic review of the literature was performed. Observational and experimental studies of pediatric and adult populations that managed recurrent ICEP with monoclonal antibodies were included. Data search, selection, and extraction were performed by two independent reviewers. RESULTS 937 studies were found. After applying the inclusion and exclusion criteria, 37 titles remained for the final analysis: a retrospective, observational, real-life study, two case series publications, and 34 case reports published in academic poster sessions and letters to the editor. In general, the use of monoclonal antibodies approved for severe asthma could be useful for the control of ICEP, since most of the results show a good response for clinical and radiological outcomes. Biological drugs seem to be a safer option for controlling relapses in ICEP, allowing lowering/suspension of OSs, and sometimes replacing them in patients intolerant to them, patients with significant comorbidities, and patients who have already developed adverse events. CONCLUSION The extent of the evidence supporting management of ICEP with monoclonal antibodies against IL-5 and IgE (omalizumab) is limited, but it could be promising in patients who present frequent relapses, in cortico-dependent individuals, or in patients in whom the use of steroids is contraindicated. The extent of the evidence for management with dupilumab is more limited. Studies with better design and structure are needed to evaluate quality of life and outcomes during a clear follow-up period. To our knowledge, this is the first scoping review of the literature showing the extent of the evidence for the management of ICEP with monoclonal antibodies.

Abstract
BACKGROUND Systemic corticosteroids (SCSs) are associated with short- and long-term adverse effects. OBJECTIVE To assess mepolizumab efficacy according to prior SCS use and characterize mepolizumab's SCS-sparing capabilities, in patients with severe chronic rhinosinusitis with nasal polyps. METHODS In the randomized, double-blind, phase III SYNAPSE trial (NCT03085797), adults with severe chronic rhinosinusitis with nasal polyps eligible for repeat sinus surgery despite standard of care treatment received mepolizumab (100 mg subcutaneously) or placebo every 4 weeks for 52 weeks. The impact of prior SCS courses (0/1/>1) on mepolizumab versus placebo treatment responses (changes from baseline in total endoscopic nasal polyp [week 52], nasal obstruction visual analog scale [weeks 49-52], and 22-item Sino-Nasal Outcome Test total [week 52] scores) was analyzed post hoc. To characterize mepolizumab's SCS-sparing capabilities, time-to-first SCS course for nasal polyps (prespecified) and total prednisolone-equivalent oral corticosteroid dose by patient baseline characteristics (post hoc, in patients with ≥1 SCS course during SYNAPSE) were assessed up to week 52. RESULTS Mepolizumab versus placebo improved treatment responses, irrespective of prior SCS use. By week 52, the probability of requiring SCSs for nasal polyps (Kaplan-Meier estimate [95% CI]) was lower with mepolizumab (25.4% [20.0-32.1]) versus placebo (37.5% [31.1-44.6]). In patients requiring 1 or more dose of SCSs, total (mean ± SD mg/y) prednisolone-equivalent oral corticosteroid dose was lower with mepolizumab (438.9 ± 350.40) versus placebo (505.2 ± 455.091), overall and irrespective of prior sinus surgeries, blood eosinophil count, or comorbidities. CONCLUSIONS Mepolizumab is associated with clinical benefits in patients with severe chronic rhinosinusitis with nasal polyps regardless of prior SCS use and has an SCS-sparing effect.

Abstract
Purpose When first-line chronic rhinosinusitis (CRS) treatment fails, patients can either be treated with oral or injected systemic corticosteroids. Although the EPOS and international guidelines for CRS do not mention injected corticosteroids, it is commonly used by ear, nose, and throat specialists. While the risks of systemic corticosteroids, in general, are known, the pros and cons of injected and oral corticosteroids (OCS) in CRS treatment are unclear. Methods A systematic review of studies that report the effects and/or side effects of injected and oral corticosteroids in the treatment of CRS was made according to the PRISMA guidelines. Results Altogether, 48 studies were included, only five studies reported on injected corticosteroids, and five attended with side effects. Three studies found beneficial effects of OCS perioperatively on sinus surgery, while four articles found no effect. Nineteen articles reported that OCS resulted in an improvement in symptoms. Two articles presented a longer-lasting effect of injected corticosteroids than OCS. Three studies reported adverse side effects of systemic corticosteroids, while two studies showed no adverse side effects. One study showed less adrenal suppression after injected corticosteroids compared to OCS. The evidence is not strong but shows a positive effect of systemic corticosteroids that lasts longer with injections. Conclusion Although systemic corticosteroids are widely used to treat CRS, there is a lack of studies comparing the OCS and injected corticosteroids. The evidence is sparse, however, injected steroids show longer effects with fewer side effects. An RCT study is needed to compare OCS and injected corticosteroids.

Abstract
Systemic corticosteroids (SCS) are a highly effective treatment for acute exacerbations and long-term symptom control in asthma. Long-term SCS use is highly prevalent across all asthma severities, occurring in over 20% of patients with severe or uncontrolled disease globally. It is now well known that exposure to both long-term and repeated acute courses of SCS is associated with a high risk of serious adverse effects (AEs), such as osteoporosis, and metabolic and cardiovascular complications, especially when prescribed onto a background of other corticosteroids. The aim of this call-to-action article, endorsed by the World Allergy Organization and the Respiratory Effectiveness Group, is to review the accumulating evidence on the burden of SCS on patients with asthma and provide an overview of potential strategies for implementing SCS Stewardship. Primary prevention of exacerbations and improvement of asthma control is a key first step in achieving SCS Stewardship, by optimizing maintenance asthma medications and addressing modifiable risk factors, such as adherence and inhaler technique. Other key elements of SCS Stewardship include increasing appropriate specialist referrals for multidisciplinary review, assessment of biomarkers, and consideration of oral corticosteroid-sparing add-on therapies (eg, biologics). In cases where SCS use is deemed clinically justified, it should be tapered to the lowest possible dose. In addition, patients receiving long-term SCS or frequent acute courses should be closely monitored for emergence of SCS-related AEs. Because of the extensive data available on the costly and burdensome AEs associated with SCS use, as well as the range of treatment options now available, there is a need for healthcare providers (HCPs) to carefully evaluate whether the benefits of SCS outweigh the potential harms, to adopt SCS-sparing and Stewardship strategies, and to consider alternative therapies where possible. Development of a structured and collaborative SCS Stewardship approach is urgently required to protect patients from the potential harm of SCS use.

Abstract
OBJECTIVES The objective of the present study was to determine the use of systemic corti-costeroids (SCs) in patients with bronchial asthma using big data analysis. METHODS We performed an observational, retrospective, noninterventional study based on secondary data captured from free text in the electronic health records. This study was per-formed based on data from the regional health service of Castille-La Mancha (SESCAM), Spain. We performed the analysis using big data and artificial intelligence via Savana® Manager version 3.0. RESULTS During the study period, 103 667 patients were diagnosed with and treated for asthma at different care levels. The search was restricted to patients aged 10 to 90 years (mean age, 43.5 [95%CI, 43.4-43.7] years). Of these, 59.8% were women. SCs were taken for treatment of asthma by 58 745 patients at some point during the study period. These patients were older, with a higher prevalence of hypertension, dyslipidemia, diabetes, ob-esity, depression, and hiatus hernia. SCs are used frequently in the general population with asthma (31.4% in 2015 and 39.6% in 2019). SCs were prescribed mainly in primary care (59%), allergy (13%) and pulmonology (20%). The frequency of prescription of SCs had a direct impact on the main associated adverse effects. CONCLUSION In clinical practice, SCs are frequently prescribed to patients with asthma, especially in primary care. Use of SCs is associated with a greater number of adverse events. It is necessary to implement measures to reduce prescription of SCs to patients with asthma, especially in primary care.

Abstract
Introduction The administration of systemic corticosteroids is a key strategy for improving COVID-19 outcomes. However, evidence is lacking on combination therapies of antiviral agents and systemic corticosteroids. The objective of this study was to investigate the efficacy and safety of the combination therapy of favipiravir and methylprednisolone in preventing respiratory failure progression in patients with COVID-19 and non-critical respiratory failure. Methods We conducted a multicenter, open-label, single-arm phase II study. The patients received favipiravir 3600 mg on the first day, followed by 1600 mg for a total of 10–14 days. Methylprednisolone was administered intravenously at 1 mg/ideal body weight (IBW)/day from days 1 to 5, followed by 0.5 mg/IBW/day from days 6 to 10 if clinically indicated. The primary endpoint was the proportion of patients requiring mechanical ventilation (MV) (including noninvasive positive pressure ventilation) or those who met the criteria for tracheal intubation within 14 days of the study treatment initiation (MVCTI-14). Results Sixty-nine patients were enrolled and underwent the study treatment. Of them, the MVCTI-14 proportion was 29.2% (90% confidence interval 20.1–39.9, p = 0.200). The proportion of patients who required MV or who died within 30 days was 26.2%, and 30-day mortality was 4.9%. The most significant risk factor for MVCTI-14 was a smoking history (odds ratio 4.1, 95% confidence interval 1.2–14.2). The most common grade 3–4 treatment-related adverse event was hyperglycemia, which was observed in 21.7%. Conclusion The MVCTI-14 proportion did not reach a favorable level in the clinical trial setting with the threshold of 35%. However, the proportion of MV or death within 30 days was 26.6%, which might be close to the findings (28.1%) of the RECOVERY trial, which showed the efficacy of dexamethasone for patients with COVID-19 and non-critical respiratory failure. Further evaluation of this combination therapy is needed. Clinical Trial Registration Japan Registry of Clinical Trials (jRCT) identifier jRCTs041200025.

Abstract
BACKGROUND Atrioventricular conduction delays (AVCD) are common after transcatheter aortic valve implantation (TAVI) and frequently require implantation of a permanent pacemaker (PPM). Autopsy studies demonstrated the role of ischemia, inflammation, and oedema in the pathogenesis of AVCD. Corticosteroids (CS) reduce inflammation and oedema and hence might lead to a lower rate of AVCD. METHODS Based on a prospective single-center registry, we performed a propensity score (PS) matched analysis of subjects treated with or without systemic CS (>2.5 mg prednisolone-equivalent per day) at the time of TAVI. The primary endpoint was a composite of PPM-implantation and new-onset left bundle branch block (LBBB) within 30 days after TAVI. RESULTS Among 2213 consecutive patients undergoing TAVI (51.5% female, mean age 82.1 ± 6.1 years) 89 patients were treated with systemic CS, of which 87 were included in the PS matched analysis. At 30 days, rates of the composite of PPM and LBBB were comparable between patients with versus without CS both in the overall cohort (33.7% versus 33.0%, p = 0.89) and the PS matched cohort (34.5% versus 40.2%, p = 0.443). There were no differences in a composite of major or minor vascular complications and major or life-threatening bleeding events between patients with versus without CS in the overall cohort (34.8% versus 26.6%, p = 0.088) or the PS matched cohort (33.3% versus 33.3%, p ≥ 0.999). CONCLUSION In this exploratory study, intake of systemic CS among patients undergoing TAVI was not associated with differences in rates of AVCD, vascular complications, or bleeding events after TAVI.

Abstract
BACKGROUND Hashimoto's encephalopathy, also known as steroid responsive encephalopathy, is associated with thyroid antibodies (SREAT) and is a rare but serious form of encephalopathy. In this paper, we describe the signs, symptoms, outcome, and treatments as noted in the case reports reviewed. METHODS We searched PubMed, Embase, and the Cochrane library for articles in which cases of Hashimoto's encephalopathy were described. The case description had to include the diagnosis, age, sex, presenting symptoms, and diagnostic tests. RESULTS We retrieved 360 articles and 65 fulfilled the inclusion criteria. These articles gave reports of 100 cases, with a mean age of 10.9 (range 2.8-19), 78 of whom were female. Epilepsy (79) - including epileptic state [24] - behavioural problems [36], hallucinations [21], headache [21], and decline in school performance [19] were most often reported. Antithyroid peroxidase (aTPO) was reported elevated in all patients. Most children [70] recovered fully, however 16 had late sequelae, mostly epilepsy. Therapies used include steroids, intravenous gammaglobulines, and cytostatics. CONCLUSIONS Epilepsy, behavioural problems, decline in school performance, and hallucinations are frequent symptoms of Hashimoto's encephalopathy. Steroids are the basis of treatment, although other immunomodulatory drugs seem to be successful. About one in ten children will experience late sequelae. In any child with unexplained neurological, psychiatric, or psychological dysfunction, serum anti-thyroidperoxidase (aTPO) should be determined.

Abstract
The aim of this study was to clarify the clinical and microbiological characteristics of Corynebacterium bacteremia in hematological patients. We retrospectively reviewed the medical records of patients with Corynebacterium bacteremia from April 2013 to June 2018. The causative Corynebacterium species were identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Drug susceptibility tests were performed using the broth microdilution method recommended by the Clinical and Laboratory Standards Institute. In total, 147 cases of Corynebacterium bacteremia were identified during the study period. Corynebacterium striatum was the most frequent pathogen. Catheter-related bloodstream infection was diagnosed in 19.7% of all patients, and moderate/severe oral or severe gastrointestinal mucosal impairment was detected in 19.7%. Polymicrobial infection was found in about 20% of cases, with Enterococcus faecium being the most frequent isolate. The overall 30-day mortality was 34.7% (51/147). Multivariate analysis showed that E. faecium co-infection (odds ratio (OR) 9.3; 95% confidence interval (CI) 2.1-40), systemic corticosteroids (OR 3.6; 95% CI 1.4-8.9), other immunosuppressive drugs (OR 0.32; 95% CI 0.13-0.76), and a Pitt bacteremia score ≥4 (OR 12; 95% CI 3.9-40) were significant risk factors for overall 30-day mortality. The drug susceptibility rates for beta-lactam antimicrobial agents were quite low. All isolates were susceptible to glycopeptides and linezolid. However, some C. striatum isolates were resistant to daptomycin. Corynebacterium bacteremia can occur in the presence of several types of mucosal impairment. Our drug susceptibility data indicate that Corynebacterium bacteremia in hematological patients could be treated by glycopeptides or linezolid.

Abstract
BACKGROUND The impact of prior exposure to systemic corticosteroids on COVID-19 severity in patients hospitalized for a SARS-CoV-2 pneumonia is not known. The present study was designed to answer to this question. METHODS The population study was the Covid-Clinic-Toul cohort which records data about all hospitalized patients with a positive reverse transcriptase polymerase chain reaction for a SARS-CoV-2 infection at Toulouse University hospital, France. Exposure to systemic corticosteroids was assessed at hospital admission. A propensity score (PS) according to corticosteroid exposure was calculated including comorbidities, clinical, radiological and biological variables that impact COVID-19 severity. The primary outcome was composite, including admission to intensive care unit, need of mechanical ventilation and death occurring during the 14 days after hospital admission. Logistic regression models adjusted for the PS (overlap weighting) provided odds ratios (ORs) and their 95% confidence intervals (95% CIs). RESULTS Overall, 253 patients were included in the study. Median age was 64 years, 140 patients (59.6%) were men and 218 (86.2%) had at least one comorbidity. Seventeen patients (6.7%) were exposed to corticosteroids before hospital admission. Chronic inflammatory disease (n = 8) was the most frequent indication. One hundred and twenty patients (47.4%) met the composite outcome. In the crude model, the OR of previous exposure to systemic corticosteroids was 1.64; 95% CI: 0.60-4.44. In the adjusted model, it was 1.09 (95% CI: 0.65-1.83). CONCLUSION Overall, this study provide some evidences for an absence of an increased risk of unfavorable outcome with previous exposure to corticosteroids in the general setting of patients hospitalized for COVID-19.

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
Since their introduction many decades ago, systemic corticosteroids have become a mainstay treatment for asthma. Despite being a highly effective therapy, corticosteroids can cause significant adverse effects in patients. This results in a "double hit" for some patients as they suffer the burden of disease as well as the burden of treatment-induced morbidity.This article aims to raise awareness of the potential, harmful side effects of prolonged or repeated exposure to systemic corticosteroids in asthma. It also highlights the importance of referral of the appropriate patients with asthma from primary care for specialist assessment once other considerations such as adherence, inhaler technique and co-morbidity have been evaluated. We propose a simple decision step that may help busy primary care physicians and general practitioners to identify patients who could benefit from specialist assessment.Our decision step suggests that a patient with asthma should be reviewed at least once by an asthma specialist if he/she (i) has received ≥2 courses of oral corticosteroids in the previous year; asthma remains uncontrolled despite good adherence and inhaler technique; or (ii) has attended an emergency department or was hospitalized for asthma care.Such referral could facilitate wider access to diagnostic tools, in-depth assessment of confounding comorbidities, and non-corticosteroid-based therapies as needed, which may be unavailable in primary practice.

Abstract
Bronchopulmonary dysplasia (BPD) is the most common serious complication associated with preterm birth. Infants with severe BPD often require prolonged and intensive pulmonary care. Among those with the most severe lung disease, this care may include tracheostomy and long-term invasive mechanical ventilation. Although there is a plethora of data on long term respiratory and developmental outcomes of BPD survivors, relevant information on BPD survivors requiring chronic respiratory failure are limited. When compared to those born at term gestation, infants with BPD requiring chronic ventilation are at increased risk of hospitalizations and develop more frequent lower respiratory infections. In childhood and young adulthood, spirometry often shows an obstructive flow pattern. From a neurodevelopmental standpoint, the short-term outcomes appear optimistic, with improvement in growth and increased participation in development-promoting activities. Nonetheless, children born prematurely are vulnerable for long term cognitive, educational and behavioral impairments. BPD is an additional risk factor which exacerbates these deficits, thus contributing to lifelong neurodevelopmental impairments of prematurity.

Abstract
BACKGROUND Asthma exacerbations are a common and important cause of attendance at emergency departments (ED) and subsequent hospital admissions. Despite previous reviews reporting that in acute settings the risk of hospital admission is reduced with the use of high doses of inhaled corticosteroids (ICS), this evidence has not changed clinical practice. OBJECTIVE To estimate the efficacy of ICS in the treatment of acute asthma in ED. METHODS Randomized controlled trials were identified using PubMed, The Cochrane Library, and EMBASE. The primary outcome was hospital admission rates. The primary comparison was between administration of ICS in addition to systemic corticosteroids (SCS) and to SCS alone. Secondary comparisons were ICS alone compared with SCS alone and ICS compared with placebo. RESULTS There were 25 studies involving 2733 participants. For the primary comparison, ICS in addition to SCS reduced the risk of hospital admission compared with SCS; fixed-effects odds ratio (95% confidence interval) 0.73 (0.57-0.94). Lung function was poorly reported. There was moderate evidence of an improvement in clinical scores and vital signs with ICS in addition to SCS. Relatively few studies reported adverse events. CONCLUSION There is moderate evidence that high doses of ICS, in addition to SCS, reduce the risk of hospital admission in ED treatment of moderate-to-severe asthma exacerbations. Further research is required to determine their optimal role in both ED and outpatient settings.

Abstract
Introduction: Systemic corticosteroids (SCS) are effective anti-inflammatory therapies for patients with severe or persistent asthma. Use of SCS reduces blood eosinophil counts; the magnitude and duration of reduction in real-world settings needs further investigation. Objective: To examine the SCS effect on blood eosinophil counts over time among patients with asthma in a real-world setting. Methods: This retrospective study used Reliant Medical Group (Worcester, MA) electronic medical records between January 2011 and December 2015. Patients aged ≥12 years with ≥1 SCS prescription (first: index date), ≥1 asthma diagnosis, and ≥1 eosinophil count in each 12-month pre- and post-index periods were included for the study. Endpoints included SCS treatment patterns, time to SCS discontinuation, and changes in index blood eosinophil counts (≥150, ≥300, and ≥400 cells/µL) with SCS initiation and discontinuation. Results: At index visit, 642 of 1198 included patients had a blood eosinophil count ≥150 cells/µL. After an average initial SCS prescription of 35 mg/day, mean (% change) eosinophil counts at month 1 in the ≥150, ≥300, and≥400 cells/µL subgroups decreased from index by 112 (-30%), 202 (-34%), and 290 (-36%) cells/µL, respectively. Of the patients with an eosinophil count ≥150 cells/µL at index, who discontinued SCS within 7, 14, or 21 days after the index date, 21%, 26%, and 25% had an eosinophil count <150 cells/µL 1-month post-index, respectively. Conclusion: Blood eosinophil counts decreased following initiation of SCS therapy and had not returned to index levels several weeks after SCS discontinuation. The time frame of SCS discontinuation is an important consideration when identifying patients with eosinophilic asthma.

Abstract
Guideline-based management of asthma focuses on disease severity and choosing the appropriate medical therapy to control symptoms and reduce the risk of exacerbations. However, irrespective of asthma severity and often despite optimal medical therapy, patients may experience acute exacerbations of symptoms and a loss of disease control. Asthma exacerbations are most commonly triggered by viral respiratory infections, particularly with human rhinovirus. Given the importance of these events to asthma morbidity and health care costs, we will review common inciting factors for asthma exacerbations and approaches to prevent and treat these events.

Abstract
All definitions of bronchopulmonary dysplasia (BPD) have limitations and a new definition for the purpose of clinical research, benchmarking, and prognostic prediction is needed. Different inhaled and systemic drugs are currently used to prevent or treat BPD. Despite some positive effects on BPD, more information about the effects of inhaled corticosteroids is required to assess overall efficacy and associated risks. One needs to balance the risks of neurodevelopmental impairment owing to systemic corticosteroids against those of BPD itself. Future studies should, therefore, focus on infants with a very high risk of developing BPD and include pharmacokinetics and long-term developmental outcomes.

Abstract
PURPOSE To investigate the long-term efficacy and safety of interferon alpha-2a (IFNα-2a) in Chinese patients with Behçet's uveitis (BU) refractory to conventional therapy. METHODS In a prospective observational cohort study, 127 patients were treated with an initial dosage of 3 million units per day in the first three months, followed by gradual tapering of the dose. RESULTS After 3 months of treatment, IFNα-2a was shown to be effective in 115 cases (91%). At the end of the 1-year follow-up, the frequency of ocular relapses decreased to 1.59 ± 1.68 per year (ranging 0-6) (p < 0.001), as compared to 5.09 ± 2.51 per year (ranging 3-15). Moreover, the frequency of oral ulcer relapses also decreased to 2.49 ± 1.84 per year (ranging 0-6) (p < 0.001), as compared to 8.20 ± 3.72 per year (ranging 2-10). Visual improvement or stability was observed in 32 patients (59%) in these 54 patients. During a mean follow-up of 11 months (range 3-33), the mean final VA (logMAR) had progressed from 1.0 logMAR to 0.8 logMAR in all treated patients. CONCLUSIONS Long-term low dose of IFNα-2a is useful in treating Chinese BU patients who do not respond adequately to conventional therapy.

Abstract
Background The most commonly applied treatment for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) is a 5-day course of high-dose systemic corticosteroids. However, this treatment has not been shown to reduce mortality and can potentially have serious side effects. Recent research has shown that, presumably, only a subgroup of COPD patients identifieable by blood eosinophil count benefit from a rescue course of prednisolone. By applying a biomarker-guided strategy, the aim of this study is to determine whether it is possible to reduce the use of systemic corticosteroids in AECOPD without influencing the outcome. Methods This is an ongoing prospective multicenter randomized controlled open label trial comprising 320 patients with AECOPD recruited from four hospitals in Denmark. The patients are randomized 1:1 to either standard care or eosinophil-guided corticosteroid-sparing therapy where prednisolone is not administered if the daily blood sampling reveals an eosinophil level below 0.3 × 109 cells/L. The primary endpoint is length of hospital stay within 14 days after recruitment. The secondary endpoints are treatment failure, 30-day mortality rate, COPD related re-admission rate, change in FEV1, and a number of adverse effect measures obtained within 3 months after the index hospitalisation date related to corticosteroid usage. Discussion This will be a very large RCT providing knowledge about the effectiveness of individualized biomarker-guided corticosteroid therapy in hospitalised patients with AECOPD.

Abstract
Background Asthma is the most common chronic disease in childhood and places a significant burden on public and private health systems. This retrospective cohort analysis utilised administrative healthcare claims data (US Clinformatics™ Multiplan database; compliant with the US Department of Health & Human Services Health Insurance Portability and Accountability Act) to characterise asthma exacerbations requiring intervention in a US paediatric patient population. Methods Patients aged > 1–17 years with a recorded asthma diagnosis and receiving treatment were identified in the US Clinformatics™ Multiplan database over a 9-year period (2004–2012). Both incident and prevalent cases of asthma were included, with the most recently recorded asthma diagnosis designated as the index date. The 12-month period following the index date was analysed for asthma exacerbations, defined as an event requiring treatment with systemic corticosteroid or resulting in an asthma-related hospitalisation or emergency department visit. Results Data from 734,114 children with asthma (41.5 % females, 58.5 % males) were analysed, of this cohort 34.4 % experienced ≥ 1 exacerbation during the follow-up period. The proportion who experienced ≥ 1 exacerbation increased from 28.9 % in 2004 to 36.3 % in 2012, based on the reported index date. Their mean annual exacerbation frequency was 1.4; 85.8 % of exacerbations were defined by systemic corticosteroids use. A consistent trend of increased exacerbation incidence in the fall and early winter was observed, in particular exacerbations defined by systemic corticosteroid use. A greater proportion of asthma-related hospitalisations were associated with younger age. Conclusions Approximately one-third of children experienced ≥ 1 exacerbation in real-world clinical practice. A targeted treatment approach with a focus on those with a history of recurrent exacerbations is recommended to improve asthma control. This targeted approach could also minimise the frequent systemic corticosteroid exposure particularly at an early age when side effects of systemic corticosteroids are more pronounced.

Abstract
BACKGROUND Many patients with severe asthma require maintenance treatment with systemic corticosteroids (SCSs) to control daily symptoms and prevent serious acute exacerbations, but chronic SCS use is associated with complications. OBJECTIVE We sought to evaluate the risk of SCS-related complications by SCS exposure and quantify the associated health care costs and resource use in patients with severe asthma. METHODS We performed a longitudinal, open-cohort, observational study using health insurance claims data (1997-2013: Medicaid) from Florida, Iowa, Kansas, Missouri, Mississippi, and New Jersey. Eligible patients were 12 years old or older with 2 or more asthma diagnoses and had more than 6 months of continuous SCS use. An open-cohort approach was used to classify patients' follow-up into low, medium, and high SCS exposure (≤ 6, >6-12, and >12 mg/d, respectively). Multivariate generalized estimating equation models were used to estimate the adjusted risk of SCS-related complications for patients with medium and high exposure compared with patients with low exposure and quantify the resulting health care resource use and costs. RESULTS The study included 3628 patients (mean age, 57.6 years; 68% female). Patients with medium and high SCS exposure had significantly higher risks of SCS-related complications, including infections and cardiovascular, metabolic, psychiatric, ocular, gastrointestinal, and bone-related complications (odds ratio, 1.23-2.12 by complication; P < .05 for all but one) versus those with low (reference group) SCS exposure. Medium and high SCS exposure were also associated with significantly more emergency department visits (incidence rate ratios, 1.31 [P = .0004] and 1.78 [P < .0001]) and inpatient visits (incidence rate ratios, 1.25 [P < .0001] and 1.59 [P < .0001]) versus low SCS exposure. CONCLUSIONS A significant dose-response relationship was demonstrated between chronic SCS use and risk of SCS-related complications in patients with severe asthma. Effective SCS-sparing strategies might reduce the burden associated with SCS-related complications in patients with severe asthma.

Abstract
Purpose Changes in sputum microbiology following antibiotic treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD), including patterns of bacteriological relapse and superinfection are not well understood. Sputum microbiology at exacerbation is not routinely performed, but pathogen presence and species are determinants of outcomes. Therefore, we determined whether baseline clinical factors could predict the presence of bacterial pathogens at exacerbation. Bacterial eradication at end of treatment (EOT) is associated with clinical resolution of exacerbation. We determined the clinical, microbiological and therapeutic factors that were associated with bacteriological eradication in AECOPD at EOT and in the following 8 weeks. Methods Sputum bacteriological outcomes (i.e., eradication, persistence, superinfection, reinfection) from AECOPD patients (N = 1352) who were randomized to receive moxifloxacin or amoxicillin/clavulanate in the MAESTRAL study were compared. Independent predictors of bacterial presence in sputum at exacerbation and determinants for bacteriological eradication were analyzed by logistic regression and receiver operating characteristic (ROC) analyses. Results Significantly greater bacteriological eradication with moxifloxacin was mainly driven by superior Haemophilus influenzae eradication (P = 0.002, EOT). Baseline clinical factors were a weak predictor of the presence of pathogens in sputum (AUCROC = 0.593). On multivariate analysis, poorer bacterial eradication was associated with antibiotic resistance (P = 0.0001), systemic steroid use (P = 0.0024) and presence of P. aeruginosa (P = 0.0282). Conclusions Since clinical prediction of bacterial presence in sputum at AECOPD is poor, sputum microbiological analysis should be considered for guiding antibiotic therapy in moderate-to-severe AECOPD, particularly in those who received concomitant systemic corticosteroids or are at risk for infection with antibiotic-resistant bacteria.

Abstract
There is a potential for significant complications from the medical and surgical treatment of rhinosinusitis because of the intimate relationship between the paranasal sinuses and surrounding vital structures. Familiarity with the complex anatomic relationships between the skull base and other critical structures and knowledge of pharmacologic properties of commonly used medical therapies are essential for preventing serious and harmful seqsuelae. The authors hope that this review represents a valuable addition to the otolaryngologist-in-training's therapeutic armamentarium, and also serves as a reminder of the potential pitfalls for the experienced sinus surgeon.
