Mountain R, Duan KI, Johnson KM. Benefit-Harm Analysis of Earlier Initiation of Triple Therapy for Prevention of Acute Exacerbation in Patients with Chronic Obstructive Pulmonary Disease. Ann Am Thorac Soc 2024; 21:1139-1146. [PMID: 38578813 DOI: 10.1513/annalsats.202311-990oc] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 04/04/2024] [Indexed: 04/07/2024] Open
Abstract
Rationale: Reducing the risk of exacerbation is a fundamental goal in managing stable chronic obstructive pulmonary disease (COPD). Guidelines recommend triple therapy (inhaled corticosteroids, long-acting muscarinic antagonists, and long-acting β-agonists) only as a stepup from dual therapy (long-acting muscarinic antagonists and long-acting β-agonists) for patients at continued high risk of exacerbation, because of the trade-off of an increased risk of pneumonia associated with inhaled corticosteroid-containing therapies. However, there is little evidence on the optimum timing of initiating triple therapy. Objectives: To perform a benefit-harm analysis to evaluate the net benefit of earlier initiation of triple therapy for the prevention of acute exacerbations in patients with COPD compared with standard timing recommended in current guidelines. Methods: We used a validated whole-disease microsimulation model of COPD in the Canadian general population aged ⩾40 years to determine the benefit versus harm of earlier initiation of triple therapy over a 20-year time horizon compared with standard care. We assessed net change in quality-adjusted life-years (QALYs) from the reduction in risk of acute exacerbations and the increased risk of treatment-related pneumonia in subgroups of patients with COPD defined by exacerbation history, symptoms, and disease severity. Model parameters were determined from clinical trials and other published literature. Key parameters were varied in one-way sensitivity analysis. Results: In patients at high risk of acute exacerbation (54.7% female; mean age, 74.0 yr; 68% Global Initiative for Chronic Obstructive Lung Disease grades I and II), earlier initiation of triple therapy was associated with a net QALY gain of 4.8 per 100 patients with COPD over 20 years compared with standard care. The net QALY gain increased to 5.9 per 100 patients in the subgroup of patients with a high symptom burden (modified Medical Research Council dyspnea scale score, >1). Earlier initiation remained net beneficial in all subgroup and sensitivity analysis scenarios. Conclusions: Modeling suggests that earlier initiation of triple therapy is likely to be net beneficial for patients at high risk of acute exacerbation, with an even greater benefit to patients with a high symptom burden. Further clinical research is needed to verify these findings in empirical studies.

Abstract
BACKGROUND Within primary care there exists a cohort of patients misdiagnosed with Chronic Obstructive Pulmonary Disease (COPD). Misdiagnosis can have a detrimental impact on healthcare finances and patient health and so understanding the factors leading to misdiagnosis is crucial in order to reduce misdiagnosis in the future. The objective of this study is to understand and explore the perceived causes of COPD misdiagnosis in primary care. METHODS A sequential mixed methods study, quantifying prevalence and features of patients misdiagnosed with COPD in primary care followed by a qualitative analysis to explore perceived causes of misdiagnosis. Quantitative data was collected for 206 patients identified as misdiagnosed with COPD within the INTEGR COPD study (NCT03482700). Qualitative data collected from 21 healthcare professionals involved in providing COPD care and 8 misdiagnosed patients who were recruited using a maximum variation purposive sampling. RESULTS Misinterpretation of spirometry results was the prevailing factor leading to patients initially being misdiagnosed with COPD, affecting 59% of misdiagnosed patients in this cohort. Of the 99 patients who were investigated for their underlying diagnosis; 41% had normal spirometry and 40% had asthma. Further investigation through qualitative methodology uncovered reluctance to challenge historical misdiagnoses and challenges in differential diagnosis as the underlying explanations for COPD misdiagnosis in this cohort. CONCLUSIONS Patients historically diagnosed with COPD without spirometric evidence are at risk of remaining labelled and treated for COPD despite non-obstructive respiratory physiology, leading to a persistent cohort of patients misdiagnosed with COPD in primary care. The lack of spirometry services during and after the COVID19 pandemic in primary care risks adding to the cohort of misdiagnosed patients. Support from respiratory specialists can potentially help to reduce the prevalence of COPD misdiagnosis in primary care. TRIAL REGISTRATION NCT03482700.

Abstract
Purpose To determine the risk of coronavirus disease 2019 (COVID-19) infection, hospitalization, and death in the era of COVID-19 vaccination among patients with noninfectious uveitis (NIU) taking immunosuppressive therapies. Design Retrospective cohort study from July 1, 2021, to June 30, 2022, using data from the Optum Labs Data Warehouse (OLDW) de-identified claims database. Participants Patients with a diagnosis of NIU from January 1, 2017, and who had ≥ 1 year of continuous enrollment in the OLDW. Methods Incidence rates (IRs) were calculated for each COVID-19 outcome. Unadjusted and adjusted hazard ratios (HRs) were estimated for each variable and COVID-19 outcome using Cox proportional hazards models with time-updated dichotomous indicators for outpatient immunosuppressive medication exposure. To assess the dose-dependent effect of systemic corticosteroid (SC) exposure, the average daily dose of prednisone over the exposed interval was included in the adjusted models. Main Outcome Measures Hazard ratios and IRs for COVID-19 infection, hospitalization, and death. Results This study included 62 209 patients with NIU. A total of 12 895 (20.7%) were exposed to SCs during the risk period. Incidence rates were increased when exposed to SCs versus unexposed for all COVID-19 outcomes. Incidence rates were also increased for all COVID-19 outcomes when exposed to SCs without COVID-19 vaccination versus exposed to SCs with ≥ 1 vaccination. In adjusted models, SCs were associated with increased risk of COVID-19 infection (HR, 3.57; 95% confidence interval [CI], 3.24-3.93; P < 0.0001), hospitalization (HR, 2.75; 95% CI, 2.07-3.65; P < 0.0001), and death (HR, 2.49; 95% CI 1.29-4.82; P = 0.007). Incremental increases in SC dose were associated with a greater risk for all outcomes. Disease-modifying anti-rheumatic drugs were associated with a decreased risk of infection (HR, 0.84; 95% CI, 0.74-0.96; P = 0.01), and tumor necrosis factor-α inhibitors were associated with an increased risk of infection (HR, 1.18; 95% CI, 1.01-1.39; P = 0.04). Conclusions Systemic corticosteroid exposure continues to be associated with greater risk of COVID-19 infection, hospitalization, and death among patients with NIU in an era of widespread COVID-19 vaccination. Unvaccinated individuals who are exposed to immunosuppressive treatments have a greater risk of severe outcomes. Coronavirus disease 2019 vaccination should be strongly encouraged in these patients.

Abstract
Chronic obstructive pulmonary disease (COPD) is a frequent, often progressive, chronic disease of the lungs. Patients with COPD often have impaired immunity; therefore, they are prone to chest infections, such as pneumonia or bronchitis. Acute exacerbations of COPD are major events that accelerate disease progression, contributing to its symptoms' burden, morbidity, and mortality. Both pneumonia and acute exacerbations in COPD are caused by bacteria against which there are effective vaccinations. Although the number of randomised controlled studies on bacterial vaccinations in COPD is limited, national and international guidelines endorse specific vaccinations in patients with COPD. This review will summarise the different types of vaccinations that prevent pneumonia and COPD exacerbations. We also discuss the results of early phase studies. We will mainly focus on Streptococcus pneumoniae, as this bacterium was predominantly investigated in COPD. However, we also review studies investigating vaccinations against Haemophilus influenzae, Moraxella catarrhalis, and Bordetella pertussis.

Abstract
Inhaled corticosteroids are known to be relatively safe for long-term use in inflammatory respiratory diseases and it has been repurposed as one of the potential therapies for outpatients with coronavirus disease 2019 (COVID-19). However, inhaled corticosteroids have not been accepted for COVID-19 as a standard therapy because of its lack of proven benefits. Therefore, this study aimed to evaluate the effectiveness of inhaled corticosteroids in patients with COVID-19. Randomized controlled trials comparing the efficacy of inhaled corticosteroid treatment in patients with COVID-19 were identified through literature electronic database searches up to March 10, 2023. Meta-analyses were conducted for predefined outcomes, and the certainty of evidence was graded using the grading of recommendations, assessment, development, and evaluation approach. Overall, seven trials (eight articles) were included in this systematic review. Compared with usual care, inhaled corticosteroids was associated with significantly improved clinical recovery at 7 and 14 days in patients with COVID-19. In subgroup analysis, only budesonide showed significant efficacy in clinical recovery, whereas no significant benefit was observed for ciclesonide. Moreover, inhaled corticosteroids use was not significantly associated with all-cause hospitalization, all-cause mortality, admission to intensive care unit, or the use of mechanical ventilation. Our systematic review used evidence with very low to moderate certainty. Although based on limited evidence, our results suggest that inhaled corticosteroids treatment, especially budesonide, improves the clinical recovery of patients with COVID-19. More trials and meta-analyses are needed to assess the efficacy of inhaled corticosteroids for COVID-19 treatment.

Abstract
Introduction: The use of steroids has been proposed as a pharmacological approach to treat the SARS-CoV-2 infection to improve outcomes. However, there are doubts about safety against the development of superinfections and their worse outcomes. Objective: To establish the relative frequency of superinfection associated with using steroids in patients with SARS-CoV-2 infection. Materials and methods: We conducted a systematic literature review and meta-analysis using PRISMA standards in 5 databases (PubMed/Scopus/Cochrane/EMBASE/Google Scholar). The search was carried out between February 2020 and May 2023. The search terms were 'steroids' or 'superinfection' 'and' followed by 'SARS-CoV-2' or 'COVID-19'. Results: We found 77 studies, but only 10 with 3539 patients were included in the systematic review. All patients developed severe disease. The documented OR for superinfection through the meta-analysis was 1.437 (95% IC 0.869-2.378) with a p-value of 0.158 without showing a risk attributed to steroids and the development of superinfections. In the Funnel-plot analysis, no publication biases were found. Conclusion: No relationship was found between using steroids and superinfection in patients with SARS-CoV-2.

Abstract
OBJECTIVE The present study aimed to evaluate HRQOL and to explore the factors associated with poor HRQOL among patients with COPD. METHODS In the present cross-sectional study, the validated St George's Respiratory Questionnaire for COPD patients (SGRQ-C) was used to evaluate HRQOL among 702 patients with COPD at two major hospitals in Jordan in the period between January and April 2022. Quantile regression analysis was used to explore the factors associated with HRQOL among the study participants. RESULTS According to SGRQ-C, the HRQOL of the study participants was greatly impaired with a total SGRQ of 55.2 (34-67.8). The highest impairment in the HRQOL was in the impact domain with a median of 58.7 (29-76.3). Increased number of prescribed medications (β = 1.157, P<0.01), older age (β = 0.487, P<0.001), male gender (β = 5.364, P<0.01), low education level (β = 9.313, P<0.001), low and moderate average income (β = 6.440, P<0.05, and β = 6.997, P<0.01, respectively) were associated with poorer HRQOL. On the other hand, being married (β = -17.122, P<0.001), living in rural area (β = -6.994, P<0.01), non-use of steroids inhalers (β = -3.859, P<0.05), not receiving long acting muscarinic antagonists (LAMA) (β = -9.269, P<0.001), not receiving LABA (β = -8.243, P<0.001) and being adherent to the prescribed medications (β = -6.016, P<0.001) were associated with improved HRQOL. Furthermore, lower disease severity (stage A, B, and C) (β = -23.252, -10.389, and -9.696 respectively, P<0.001), and the absence of comorbidities (β = -14.303, P<0.001) were associated with better HRQOL. CONCLUSIONS In order to maximize HRQOL in patients with COPD, future COPD management interventions should adopt a multidisciplinary approach involving different healthcare providers, which aims to provide patient-centered care, implement personalized interventions, and improve medication adherence, particularly for patients who are elderly, males, have low socioeconomic status, receive multiple medications and have multiple comorbid diseases.

Abstract
Few studies have directly compared the incidence of pneumonia in patients on common chronic obstructive pulmonary disease (COPD) treatments such as long-acting muscarinic antagonists (LAMA) with those on inhaled corticosteroids and long-acting β2-agonist (ICS/LABA). Moreover, risk factors for pneumonia in COPD are still unclear. We aimed to compare the incidence of pneumonia in COPD patients on LAMA and those on ICS/LABA and explored the risk factors associated with pneumonia. This nationwide cohort study used Korean National Health Insurance claim data from January 2002 to April 2016. Patients who received COPD medication, either LAMA or ICS/LABA, with the COPD diagnostic code, were selected. We enrolled patients with good compliance (medication possession ratio ≥ 80%). The primary outcome was pneumonia in COPD patients initiating LAMA or ICS/LABA. We investigated the risk factors associated with pneumonia, including the sub-types of ICS treatments. After propensity score matching, the incidence rate per 1000 person-years of pneumonia was 93.96 for LAMA (n = 1003) and 136.42 for ICS/LABA (n = 1003) patients (p < 0.001). The adjusted hazard ratio (HR) for pneumonia in patients on fluticasone/LABA was 1.496 (95% confidence interval [CI] 1.204-1.859) compared with LAMA (p < 0.001). In multivariable analysis, a history of pneumonia was a risk factor associated with pneumonia (HR 2.123; 95% CI 1.580-2.852; p < 0.001). The incidence of pneumonia was higher in COPD patients on ICS/LABA compared with those on LAMA. It is recommended that ICS use be avoided in COPD patients with high pneumonia risk.

Abstract
BACKGROUND The role of inhaled corticosteroids (ICS) in chronic obstructive pulmonary disease (COPD) has been the subject of much uncertainty. COPD clinical guidelines currently recommend selective use of ICS. ICS are not recommended as monotherapy for people with COPD, and are only given in combination with long-acting bronchodilators due to greater efficacy of combination therapy. Incorporating and critiquing newly published placebo-controlled trials into the monotherapy evidence base may help to resolve ongoing uncertainties and conflicting findings about their role in this population. OBJECTIVES To evaluate the benefits and harms of inhaled corticosteroids, used as monotherapy versus placebo, in people with stable COPD, in terms of objective and subjective outcomes. SEARCH METHODS We used standard, extensive Cochrane search methods. The latest search date was October 2022. SELECTION CRITERIA We included randomised trials comparing any dose of any type of ICS, given as monotherapy, with a placebo control in people with stable COPD. We excluded studies of less than 12 weeks' duration and studies of populations with known bronchial hyper-responsiveness (BHR) or bronchodilator reversibility. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. Our a priori primary outcomes were 1. exacerbations of COPD and 2. quality of life. Our secondary outcomes were 3. all-cause mortality, 4. lung function (rate of decline of forced expiratory volume in one second (FEV1)), 5. rescue bronchodilator use, 6. exercise capacity, 7. pneumonia and 8. adverse events including pneumonia. ]. We used GRADE to assess certainty of evidence. MAIN RESULTS Thirty-six primary studies with 23,139 participants met the inclusion criteria. Mean age ranged from 52 to 67 years, and females were 0% to 46% of participants. Studies recruited across the severities of COPD. Seventeen studies were of duration longer than three months and up to six months and 19 studies were of duration longer than six months. We judged the overall risk of bias as low. Long-term (more than six months) use of ICS as monotherapy reduced the mean rate of exacerbations in those studies where pooling of data was possible (generic inverse variance analysis: rate ratio 0.88 exacerbations per participant per year, 95% confidence interval (CI) 0.82 to 0.94; I2 = 48%, 5 studies, 10,097 participants; moderate-certainty evidence; pooled means analysis: mean difference (MD) -0.05 exacerbations per participant per year, 95% CI -0.07 to -0.02; I2 = 78%, 5 studies, 10,316 participants; moderate-certainty evidence). ICS slowed the rate of decline in quality of life, as measured by the St George's Respiratory Questionnaire (MD -1.22 units/year, 95% CI -1.83 to -0.60; I2 = 0%; 5 studies, 2507 participants; moderate-certainty evidence; minimal clinically importance difference 4 points). There was no evidence of a difference in all-cause mortality in people with COPD (odds ratio (OR) 0.94, 95% CI 0.84 to 1.07; I2 = 0%; 10 studies, 16,636 participants; moderate-certainty evidence). Long-term use of ICS reduced the rate of decline in FEV1 in people with COPD (generic inverse variance analysis: MD 6.31 mL/year benefit, 95% CI 1.76 to 10.85; I2 = 0%; 6 studies, 9829 participants; moderate-certainty evidence; pooled means analysis: 7.28 mL/year, 95% CI 3.21 to 11.35; I2 = 0%; 6 studies, 12,502 participants; moderate-certainty evidence). ADVERSE EVENTS in the long-term studies, the rate of pneumonia was increased in the ICS group, compared to placebo, in studies that reported pneumonia as an adverse event (OR 1.38, 95% CI 1.02 to 1.88; I2 = 55%; 9 studies, 14,831 participants; low-certainty evidence). There was an increased risk of oropharyngeal candidiasis (OR 2.66, 95% CI 1.91 to 3.68; 5547 participants) and hoarseness (OR 1.98, 95% CI 1.44 to 2.74; 3523 participants). The long-term studies that measured bone effects generally showed no major effect on fractures or bone mineral density over three years. We downgraded the certainty of evidence to moderate for imprecision and low for imprecision and inconsistency. AUTHORS' CONCLUSIONS This systematic review updates the evidence base for ICS monotherapy with newly published trials to aid the ongoing assessment of their role for people with COPD. Use of ICS alone for COPD likely results in a reduction of exacerbation rates of clinical relevance, probably results in a reduction in the rate of decline of FEV1 of uncertain clinical relevance and likely results in a small improvement in health-related quality of life not meeting the threshold for a minimally clinically important difference. These potential benefits should be weighed up against adverse events (likely to increase local oropharyngeal adverse effects and may increase the risk of pneumonia) and probably no reduction in mortality. Though not recommended as monotherapy, the probable benefits of ICS highlighted in this review support their continued consideration in combination with long-acting bronchodilators. Future research and evidence syntheses should be focused in that area.

Abstract
Background Chronic respiratory disease may be associated with severity of coronavirus disease 2019 (COVID-19) infection. We review a case of chronic obstructive pulmonary disease (COPD) patient who developed acute breathlessness post COVID-19 infection, also focusing on the diagnostic approach. Case A 69-year-old gentleman with background history of COPD GOLD D and ischemic heart disease was admitted with severe COVID-19 infection. He required high-flow nasal cannula upon presentation. A computed tomography pulmonary angiography (CTPA) thorax at day 10 of illness revealed moderate organizing pneumonia (OP) with emphysematous changes, without pulmonary embolism. He received oral baricitinib and intravenous methylprednisolone for 3 days, which was then followed by tapering prednisolone starting dose of 1 mg/kg/day (60 mg/day) with reduction of 10 mg prednisolone every 3 days. COPD pharmacotherapy was optimized with early utilization of dual bronchodilators and inhaled corticosteroid was withheld. He underwent inpatient pulmonary rehabilitation and was discharged with home oxygen therapy. Unfortunately, he was re-admitted after 2 weeks with shortness of breath and fever for 3 days. Blood results revealed leucocytosis with raised C-reactive protein. A repeat CTPA showed increase reticulations and crazy paving pattern with reduction in lung volume. Multidisciplinary team discussion concluded it as interstitial pneumonia with COVID-19 OP and fibrosis progression. Prednisolone was stopped and he responded well with antibiotics. A follow-up at 3 months post COVID-19 infection showed improvement of clinical symptoms with radiological resolution of ground glass changes. Conclusion Corticosteroid inhaler should be cautioned in this case, in view of recent pneumonia and non-elevated serum eosinophil count. These groups of patients should be closely followed up to unmask interstitial lung disease that may present prior to COVID-19 and worsen post-infection. Optimizing pre-existing medical conditions should be the paramount intervention.

Withdrawal of inhaled corticosteroids from patients with COPD with mild or moderate airflow limitation in primary care: a feasibility randomised trial. BMJ Open Respir Res 2022; 9:9/1/e001311. [PMID: 36041773 PMCID: PMC9438092 DOI: 10.1136/bmjresp-2022-001311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 08/01/2022] [Indexed: 11/17/2022] Open
Abstract
Background Inhaled corticosteroids (ICS) are frequently prescribed outside guidelines to patients with chronic obstructive pulmonary disease (COPD) with mild/moderate airflow limitation and low exacerbation risk. This primary care trial explored the feasibility of identifying patients with mild/moderate COPD taking ICS, and the acceptability of ICS withdrawal. Methods Open feasibility trial. Outcome measures included prevalence of suitable participants, feasibility of their identification, their willingness-to-accept open randomisation to ICS withdrawal or continuation over 6 months follow-up. Results 392 (13%) of 2967 patients with COPD from 20 practices (209 618 population) identified as eligible for ICS withdrawal by electronic search algorithm. After individual patient record review, 243 (62%) were excluded because of: severe airflow limitation (65, 17%); one or more severe or two or more moderate COPD exacerbations in the previous year (86, 22%); asthma (15, 4%); and severe comorbidities (77, 20%). After exclusion, 149 patients with COPD were invited to participate and 61 agreed to randomisation. At clinical assessment, 10 patients exhibited undocumented airflow reversibility (forced expiratory volume in 1 s (FEV1) reversibility >12% and >200 mL); 2 had suffered two or more undocumented, moderate exacerbations in the previous year; 7 had severe airflow limitation; and 2 had normal spirometry. Finally, 40 were randomised. One patient died and one was lost to follow-up. 18 (45%) of the 38 (10 withdrawal and 8 usual care) exhibited previously undocumented FEV1 variability suggestive of asthma, supported in the withdrawal group by significant associations with elevated fractional exhaled nitric oxide (p=0.04), elevated symptom score (p=0.04), poorer quality of life (p=0.04) and atopic status (p=0.01). Conclusions Identifying primary care patients with mild/moderate COPD suitable for ICS withdrawal is feasible but requires real-time verification because of unreliable recording of exacerbations and lung function. Suitable patients accepted randomisation to ICS withdrawal or continuation for the purposes of future studies. Follow-up compliance was high. Nearly 50% of participants with a diagnosis of mild/moderate COPD demonstrated previously undocumented FEV1 variability during follow-up, mandating monitoring for at least 6 months following withdrawal to exclude undiagnosed asthma.

Abstract
OBJECTIVES The objective of this study was to model the clinical and economic impact of adapting current clinical practice in the management of patients with chronic obstructive pulmonary disease (COPD) to treatment according to national and international guideline recommendations. DESIGN Treatment mapping was undertaken to hypothetically redistribute patients from current clinical practice, representing actual prescribing patterns in the UK, to an alternative recommendation-based treatment scenario, representing prescribing in accordance with either National Institute for Health and Care Excellence (NICE) guidance [NG115] or Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020 strategy. SETTING Primary care practices in the UK (1-year time horizon). PARTICIPANTS Adults with COPD undergoing long-acting inhaler maintenance therapy in the UK (N=1 067,531). INTERVENTIONS Inhaler maintenance therapy. OUTCOME MEASURES Costs and clinical outcomes (type of treatment, rates of moderate and/or severe exacerbations, and mild-to-moderate and/or severe pneumonia events) were modelled for the two alternative pathways. RESULTS Compared with current clinical practice, treating patients according to NICE guidance resulted in an estimated annual reduction in expenditure of £46.9 million, and an estimated annual reduction in expenditure of over £43.7 million when patients were treated according to GOLD 2020 strategy. Total cost savings of up to 8% annually could be achieved by treatment of patients according to either of these recommendations. Cost savings arose from a reduction in the rates of pneumonia, with an associated decrease in costs associated with antibiotic use and hospitalisation. Savings were achieved overall despite a small increase in the rate of exacerbations due to the redistribution of certain patients currently undergoing triple inhaled therapy to therapies not containing inhaled corticosteroids. CONCLUSION Redistribution of patients with COPD from current clinical practice to treatment according to published recommendations would provide substantial cost savings over the first year.

Abstract
Treatment of the cigarette smoke-associated lung disease has largely focused on broad-spectrum anti-inflammatory therapies. However, these therapies, such as high-dose inhaled corticosteroids, enhance patient susceptibility to lung infection and exacerbation. Our objective was to assess whether the host-defense peptide, human beta-defensin 2 (hBD-2), can simultaneously reduce pulmonary inflammation in cigarette smoke-exposed mice while maintaining immune competence during bacterial exacerbation. Mice were exposed to cigarette smoke acutely (4 days) or chronically (5 days/week for 7 weeks) and administered hBD-2 intranasally or by gavage. In a separate model of acute exacerbation, chronically exposed mice treated with hBD-2 were infected with non-typeable Haemophilus influenzae prior to sacrifice. In the acute exposure model, cigarette smoke-associated pulmonary neutrophilia was significantly blunted by both local and systemic hBD-2 administration. Similarly, chronically exposed mice administered hBD-2 therapeutically exhibited reduced pulmonary neutrophil infiltration and downregulated pro-inflammatory signaling in the lungs compared to vehicle-treated mice. Finally, in a model of acute bacterial exacerbation, hBD-2 administration effectively limited neutrophil infiltration in the lungs while markedly reducing pulmonary bacterial load. This study shows that hBD-2 treatment can significantly attenuate lung neutrophilia induced by cigarette smoke exposure while preserving immune competence and promoting an appropriate host-defense response to bacterial stimuli.

Ophthalmology 2022; 129:1096-1106. [PMID: 35588945 PMCID: PMC9110065 DOI: 10.1016/j.ophtha.2022.05.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 04/15/2022] [Accepted: 05/04/2022] [Indexed: 11/28/2022] Open
Abstract
Purpose To determine the dose-dependent risk of systemic corticosteroids (SCs) and the risk of other immunosuppressive therapies on coronavirus disease 2019 (COVID-19) infection, hospitalization, and death in patients with noninfectious uveitis (NIU). Design A retrospective cohort study from January 20, 2020, to December 31, 2020 (an era before widespread COVID-19 vaccination), using the Optum Labs Data Warehouse, a US national de-identified claims database. Participants Patients who had at least 1 NIU diagnosis from January 1, 2017. Methods Unadjusted and adjusted hazard ratios (HRs) were estimated for each variable and COVID-19 outcome using Cox proportional hazards models, with time-updated dichotomous indicators for outpatient immunosuppressive medication exposure. To assess the dose-dependent effect of SC exposure, the average daily dose of prednisone over the exposed interval was included in the adjusted models as a continuous variable, in addition to the dichotomous variable. Main Outcome Measures Incidence rates of COVID-19 infection, COVID-19–related hospitalization, and COVID-19–related in-hospital death. Results This study included 52 286 NIU patients of whom 12 000 (23.0%) were exposed to immunosuppressive medications during the risk period. In adjusted models, exposure to SCs was associated with increased risk of COVID-19 infection (HR, 2.66; 95% confidence interval [CI], 2.19–3.24; P < 0.001), hospitalization (HR, 3.26; 95% CI, 2.46–4.33; P < 0.001), and in-hospital death (HR, 1.99; 95% CI, 0.93–4.27; P = 0.08). Furthermore, incremental increases in the dosage of SCs were associated with a greater risk for these outcomes. Although tumor necrosis factor-α (TNF-α) inhibitors were associated with an increased risk of infection (HR, 1.48; 95% CI, 1.08–2.04; P = 0.02), other immunosuppressive treatments did not increase the risk of COVID-19 infection, hospitalization, or death. Conclusions This study from an era before widespread COVID-19 vaccination demonstrates that outpatient SC exposure is associated with greater risk of COVID-19 infection and severe outcomes in patients with NIU. Future studies should evaluate the impact of immunosuppression in vaccinated NIU patients. Limiting exposure to SCs and use of alternative therapies may be warranted.

Inhaled Corticosteroids Selectively Alter the Microbiome and Host Transcriptome in the Small Airways of Patients with Chronic Obstructive Pulmonary Disease. Biomedicines 2022; 10:biomedicines10051110. [PMID: 35625847 PMCID: PMC9138653 DOI: 10.3390/biomedicines10051110] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/06/2022] [Accepted: 05/09/2022] [Indexed: 12/13/2022] Open
Abstract
Background: Patients with chronic obstructive pulmonary disease (COPD) are commonly treated with inhaled corticosteroid/long-acting ß2-agonist combination therapy. While previous studies have investigated the host–microbiome interactions in COPD, the effects of specific steroid formulations on this complex cross-talk remain obscure. Methods: We collected and evaluated data from the Study to Investigate the Differential Effects of Inhaled Symbicort and Advair on Lung Microbiota (DISARM), a randomized controlled trial. Bronchoscopy was performed on COPD patients before and after treatment with salmeterol/fluticasone, formoterol/budesonide or formoterol-only. Bronchial brush samples were processed for microbial 16S rRNA gene sequencing and host mRNA sequencing. Longitudinal changes in the microbiome at a community, phylum and genus level were correlated with changes in host gene expression using a Spearman’s rank correlation test. Findings: In COPD patients treated with salmeterol/fluticasone, the expression levels of 676 host genes were significantly correlated to changes in the alpha diversity of the small airways. At a genus level, the expression levels of 122 host genes were significantly related to changes in the relative abundance of Haemophilus. Gene enrichment analyses revealed the enrichment of pathways and biological processes related to innate and adaptive immunity and inflammation. None of these changes were evident in patients treated with formoterol/budesonide or formoterol alone. Interpretation: Changes in the microbiome following salmeterol/fluticasone treatment are related to alterations in the host transcriptome in the small airways of patients with COPD. These data may provide insights into why some COPD patients treated with inhaled corticosteroids may be at an increased risk for airway infection, including pneumonia. Funding: The Canadian Institute of Health Research, the British Columbia Lung Association, and an investigator-initiated grant from AstraZeneca.

Abstract
Chronic obstructive pulmonary disease (COPD) is associated with a poor prognosis in patients with non-small cell lung cancer (NSCLC). However, the impact of COPD treatment on the survival of patients with advanced NSCLC remains uncertain. We retrospectively investigated COPD patients among patients newly diagnosed with advanced NSCLC between September 2005 and August 2019 at a university hospital. The clinical characteristics, lung function, and survival outcomes were analyzed and compared between patients who did and did not receive COPD treatment. Among 221 patients with advanced NSCLC and COPD, 124 patients received treatment for COPD and 97 patients did not receive treatment for COPD. Forced expiratory volume in 1 s (FEV1) % predicted value was greater in the no-treatment group than in the COPD treatment group (p < 0.001). The median overall survival (OS) of the treatment group was 10.7 months, while that of the no-treatment group was 8.7 months (p = 0.007). In the multivariate analysis, COPD treatment was independently associated with improved OS (hazard ratio 0.71, 95% confidence interval 0.53−0.95, and p = 0.021). COPD treatment was associated with improved OS in patients with advanced NSCLC and COPD. Therefore, pretreatment spirometry and maximal treatment for COPD may offer a chance of optimal management for patients with advanced NSCLC.

Abstract
Introduction Inhaled corticosteroids (ICSs) play an important role in lowering the risk of acute exacerbation of chronic obstructive pulmonary disease (COPD). However, ICSs are known to increase the risk of pneumonia. Moreover, previous studies have shown that the incidence rate of pneumonia varies depending on the type of ICS. In this study, the risk of pneumonia according to the type of ICS was investigated in a population-based cohort. Methods A retrospective cohort study was conducted using claims data of the entire population from the Korean National Health Insurance Service. Patients who were newly diagnosed with COPD and prescribed fluticasone propionate or budesonide were enrolled as study subjects. Cumulative doses of ICSs were classified into categorical variables to analyze the risk of pneumonia within identical ICS doses. Results A total of 47,473 subjects were identified and allocated as 14,518 fluticasone propionate and 14,518 budesonide users through 1:1 propensity score matching. Fluticasone propionate users were more likely to develop pneumonia than budesonide users (14.22% vs 10.66%, p<0.0001). The incidence rate per 100,000 person-years was 2,914.77 for fluticasone propionate users and 2,102.90 for budesonide users. The hazard ratio (HR) of pneumonia in fluticasone propionate compared to budesonide was 1.34 (95% CI 1.26–1.43, p<0.0001). The risk of pneumonia for fluticasone propionate compared to budesonide increased with higher ICS cumulative doses: 1.06 (0.93–1.21), 1.41 (1.19–1.66), 1.41 (1.23–1.63), and 1.49 (1.33–1.66) from the lowest to highest quartiles, respectively. Conclusion ICS types and doses need to be carefully considered during treatment with ICSs in patients with COPD.

BACKGROUND The observation of patients hospitalized for coronavirus disease (COVID-19) led us to note a lower prevalence of patients affected by chronic respiratory disease, in particular asthmatic patients, compared to the general population. Therefore, the aim of this paper is to evaluate the possible protective role of corticosteroid therapy in patients with chronic lung disease, regarding the risk of contracting severe COVID-19. MAIN BODY SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) receptors to enter the cells. Considering the high number of these receptors in patients affected by asthma and chronic obstructive pulmonary disease (COPD), the evidence that these patients do not have a high risk of hospitalization for COVID-19 needs further study to understand what the possible protective "factors" are in these patients. In particular, the finding in some studies of reduced coronavirus replication in cell lines treated with steroids, molecules commonly used for treating chronic lung diseases, needs further attention. SHORT CONCLUSION The hypothesis that corticosteroids, commonly used in treating airways diseases, might modify the severity of SARS-CoV-2 disease has become a key point and a possible predictive factor of a positive outcome of COVID-19 in patients treated everyday with these molecules.

Abstract
INTRODUCTION Patients with chronic obstructive pulmonary disease (COPD) with frequent exacerbations (ExCOPD) are commonly treated with inhaled corticosteroids (ICS) and are at risk of infections caused by potential pathogenic bacteria (PPB) including Pseudomonas aeruginosa (PsA). OBJECTIVES To investigate the association between the use of ICS and PsA infection among ExCOPD. METHODS Case-control study with longitudinal follow-up that recruited ExCOPD after a hospitalisation due to exacerbation between 2012 and 2020. Patients with isolation of PsA (COPD-PsA) in sputum either during admission or follow-up were compared with those with other or no PPB. Clinical, functional characteristics, DDD, use of ICS and survival were evaluated. Cox regression analysis was performed to evaluate the risk factors associated to PsA infection and mortality. RESULTS 358 patients (78% male, mean age 73±9 years) were enrolled and followed up for a median of 4 years (IQR=3-8). 173 patients (48.3%) had at least a positive culture for PsA. COPD-PsA had more frequent exacerbations, more severe airflow limitation and higher mortality (69.4% vs 46.5%, p<0.001). There were no differences in the use of ICS between groups but the dose of ICS was significantly higher among COPD-PsA (median of 500 µg fluticasone propionate equivalents (IQR=250-1000) vs 400 µg (IQR=200-1000), p=0.007). Blood eosinophil count (BEC) was not different between ICS users and non-users. In multivariate analysis, the dose of ICS was an independent risk factor for PsA infection and mortality but not ICS use. CONCLUSIONS ICS dose, but not its use, could be a risk factor for PsA infection in patients with severe COPD regardless of BEC.

Abstract
Literature regarding trends of incidence, mortality, and complications of acute exacerbation of chronic obstructive pulmonary disease (COPD) in the emergency departments (ED) is limited. What are trends of COPD exacerbation in ED? Data were obtained from the Nationwide Emergency Department Sample (NEDS) that constitutes a 20% sample of hospital-owned EDs and inpatient sample in the US. All ED encounters were included in the analysis. Complications of AECOPD were obtained by using ICD codes. Out of 1.082 billion ED encounters, 5,295,408 (mean age 63.31 ± 12.63 years, females 55%) presented with COPD exacerbation. Among these patients, 353,563(6.7%) had AECOPD-plus (features of pulmonary embolism, acute heart failure and/or pneumonia) while 4,941,845 (93.3%) had exacerbation without associated features or precipitating factors which we grouped as AECOPD. The AECOPD-plus group was associated with statistically significantly higher proportion of cardiovascular complications including AF (5.6% vs 3.5%; p < 0.001), VT/VF (0.14% vs 0.06%; p < 0.001), STEMI (0.22% vs 0.11%; p < 0.001) and NSTEMI (0.65% vs 0.2%; p < 0.001). The in-hospital mortality rates were greater in the AECOPD-plus population (0.7% vs 0.1%; p < 0.001). The incidence of both AECOPD and AECOPD-plus had worsened (p-trend 0.004 and 0.0003) and the trend of mortality had improved (p-trend 0.0055 and 0.003, respectively). The prevalence of smoking for among all COPD patients had increased (p-value 0.004), however, the prevalence trend of smoking among AECOPD groups was static over the years 2010-2018. There was an increasing trend of COPD exacerbation in conjunction with smoking; however, mortality trends improved significantly. Moreover, the rising burden of AECOPD would suggest improvement in diagnostics and policy making regarding management.

Abstract
RATIONALE Inhaled corticosteroids (ICS) are commonly prescribed with long-acting beta-2 agonists (LABA) in COPD. To date, the effects of ICS therapy on the airway microbiome in COPD are unknown. OBJECTIVES To determine the effects of ICS/LABA on the airway microbiome of COPD patients. METHODS Clinically stable COPD patients were enrolled into a 4-week run-in period during which ICS was discontinued and all participants were placed on formoterol 12 µg twice daily (BID). The participants were then randomized to: budesonide/formoterol (Bud + Form; 400/12 µg BID), fluticasone/salmeterol (Flu + Salm; 250/50 µg BID) or formoterol only (Form; 12 µg BID) for 12 weeks. Participants underwent bronchoscopy before and after the 12-week treatment period. The primary endpoint was the comparison of changes in the airway microbiome over the trial period between the ICS/LABA and LABA-only groups. MEASUREMENTS AND MAIN RESULTS 63 participants underwent randomization: Bud + Form (n=20), Flu + Salm (n=22) and Form (n=21) groups; 56 subjects completed all visits. After the treatment period, changes in alpha diversity were significantly different across groups, especially between Flu + Salm and Form groups (Δ richness: p = 0.02; Δ Shannon Index: p = 0.03). Longitudinal differential abundance analyses revealed more pronounced microbial shifts from baseline in the fluticasone (vs. budesonide or formoterol only) group. CONCLUSIONS Fluticasone-based ICS/LABA therapy modifies the airway microbiome in COPD, leading to a relative reduction in alpha diversity and a greater number of bacterial taxa changes. These data may have implications in patients who develop pneumonia on ICS. Clinical trial registration available at www.clinicaltrials.gov, ID:NCT02833480.

Abstract
Selective phosphodiesterase (PDE) inhibitors are a class of nonsteroid anti-inflammatory drugs for treating chronic inflammatory diseases. Modulation of systemic and airway inflammation is their pivotal mechanism of action. Furthermore, PDE inhibitors modulate cough reflex and inhibit airway mucus secretion. Roflumilast, a selective PDE4 inhibitor, has been extensively studied for the efficacy and safety in chronic obstructive pulmonary disease (COPD) patients. According to the mechanisms of action, the potential roles of PDE inhibitors in treating chronic respiratory diseases including severe asthma, asthma-COPD overlap (ACO), noncystic fibrosis bronchiectasis, and chronic cough are discussed. Since roflumilast inhibits airway eosinophilia and neutrophilia in COPD patients, it reduces COPD exacerbations in the presence of chronic bronchitis in addition to baseline therapies. The clinical studies in asthma patients have shown the comparable efficacy of roflumilast to inhaled corticosteroids for improving lung function. However, the clinical trials of roflumilast in severe asthma have been limited. Although ACO is common and is also associated with poor outcomes, there is no clinical trial regarding its efficacy in patients with ACO despite a promising role in reducing COPD exacerbation. Since mucus hypersecretion is a result of neutrophil secretagogue in patients with chronic bronchitis, experimental studies have shown that PDE4s are regulators of the cystic fibrosis transmembrane conductance regulator (CFTR) in human airway epithelial cells. Besides, goblet cell hyperplasia is associated with an increased expression of PDE. Bronchiectasis and chronic bronchitis are considered neutrophilic airway diseases presenting with mucus hypersecretion. They commonly coexist and thus lead to severe disease. The role of roflumilast in noncystic fibrosis bronchiectasis is under investigation in clinical trials. Lastly, PDE inhibitors have been shown modulating cough from bronchodilation, suppressing transient receptors potential (TRP), and anti-inflammatory properties. Hence, there is the potential role of the drug in the management of unexplained cough. However, clinical trials for examining its antitussive efficacy are pivotal. In conclusion, selective PDE4 inhibitors may be potential treatment options for chronic respiratory diseases apart from COPD due to their promising mechanisms of action.

Abstract
BACKGROUND The effect of inhaled corticosteroids (ICS) on risk of hyperglycemia in patients with chronic obstructive pulmonary disease (COPD) remains ambiguous. The aim of this study is to evaluate the association between ICS use and the incidence of hyperglycemia related adverse effects in COPD patients. METHODS Medline/PubMed, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov were searched from inception to 25 May 2020. Randomized controlled trials (RCTs) of ICS versus control (non-ICS) treatment for COPD patients reporting on risk of hyperglycemia were included. The Mantel-Haenszel method with fixed-effects modeling was used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs). RESULTS Seventeen RCTs with 43,430 subjects were included in the meta-analysis. Pooled results suggested that there was no statistically significant difference in the risk of hyperglycemia between the ICS group and the control group (RR 1.02, 95% CI 0.90-1.16, P = 0.76). In addition, no significant difference was noted in the effect on glucose level (RR 1.20, 95% CI 0.79-1.82, P = 0.40), risk of diabetes progression (RR 0.84, 95% CI 0.20-3.51, P = 0.81) and new onset diabetes mellitus (RR 1.0, 95% CI 0.88-1.15, P = 0.95) between the ICS group and the control group. These findings also were consistent across all subgroup analyses. CONCLUSIONS Use of ICS does not have an effect on the blood glucose and is not associated with the risk of new onset diabetes mellitus and diabetes progression in patients with COPD. Further RCTs exploring the association between ICS use and risk of hyperglycemia in COPD patients are still needed to verify our results of this analysis.

Abstract
BACKGROUND The aim of this work was to investigate the safety and efficacy of single-inhaler triple therapy with 12.5 μg glycopyrronium (GB)/12 μg formoterol fumarate (FF)/250 μg fluticasone propionate (FP), compared to 50 μg GB co-administered with a fixed dose of 12 μg FF/250 μg FP in subjects with COPD. METHODS This was a phase 3, randomised, double-blind, active-control, parallel-group, noninferiority study conducted at 20 sites across India. COPD patients aged ≥40 to ≤75 years, with forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) <0.70, using mono/dual therapy with inhaled corticosteroids (ICSs), long-acting muscarinic antagonists (LAMAs), or long-acting β-agonists (LABAs) for ≥1 month, were included. Subjects were randomised 1:1 to GB/FF/FP or GB+FF/FP for 12 weeks. The primary efficacy end-point was the change from baseline in trough FEV1 at the end of 12 weeks. The study is registered with the Clinical Trials Registry of India (identifier number: CTRI/2019/01/017156). RESULTS Between 23 March 2019 and 14 February 2020, 396 subjects were enrolled, with 198 patients each in the fixed-triple (GB/FF/FP) and open-triple (GB+FF/FP) groups. The difference in least-square mean (LSM) changes in pre-dose FEV1 from baseline at 12 weeks was noninferior between the groups (p<0.05). The LSM change from baseline in post-dose FEV1 was comparable (p=0.38). A superiority test showed comparable efficacy (p=0.12) for the difference in mean change from baseline in trough FEV1 between the groups. Adverse events (mild or moderate) were recorded in 25.3% and 24.9% of subjects in the GB/FF/FP and GB+FF/FP groups. CONCLUSIONS Fixed triple therapy with GB/FF/FP provides comparable bronchodilation and lung function improvement as open-triple therapy. It is safe and well tolerated in symptomatic COPD patients with a history of exacerbations.

Abstract
BACKGROUND It was reported that inhaled corticosteroids (ICS) treatment may affect local immunity and microbial community of the airway. However, whether ICS treatment increases the risk of influenza in patients with asthma remains unclear. This meta-analysis aimed to compare the risk of influenza between ICS and non-ICS treatment in patients with asthma. METHODS PubMed, Embase, Cochrane Library and Clinical Trials.gov were searched from inception until November 2019. Randomized controlled trials (RCTs) were included that compared ICS treatment with non-ICS treatment on the risk of influenza in patients with asthma. Meta-analyses were conducted by the Peto approach and Mantel-Haenszel approach with corresponding 95% CIs. RESULTS Nine trials involving 6486 patients were included in this meta-analysis. The risk of influenza was not different between ICS treatment and the control groups (Peto OR: 1.01, 95% CI 0.74-1.37, P = 0.95). The results of subgroup analyses based on durations (long-term and short-term treatment), doses (high-, medium- and low-dose treatment) and types (fluticasone and budesonide treatment) of ICS were consistent with the above pooled results. Moreover, subgroup analysis based on patients' age also revealed that use of ICS did not increase the risk of influenza. Results of the two meta-analysis approaches were similar. CONCLUSIONS Use of ICS does not increase the risk of influenza in patients with asthma. This study adds to safety evidence of ICS as a regular controller treatment for patients with asthma.

Abstract
Background: Whether all types of inhaled corticosteroids (ICSs) would increase the pneumonia risk in patients with chronic obstructive pulmonary disease (COPD) remains controversial. We aimed to assess the association between ICSs treatment and pneumonia risk in COPD patients, and the impact of medication details and baseline characteristics of patients on the association. Methods: Four databases (PubMed, Embase, Cochrane Library, and Clinical Trials.gov) were searched to identify eligible randomized controlled trials (RCTs) comparing ICSs treatment with non-ICSs treatment on the pneumonia risk in COPD patients. Pooled results were calculated using Peto odds ratios (Peto ORs) with corresponding 95% confidence intervals (CIs). Results: A total of 59 RCTs enrolling 103,477 patients were analyzed. All types of ICSs significantly increased the pneumonia risk (Peto OR, 1.43; 95% CI, 1.34–1.53). Subgroup analysis showed that there was a dose-response relationship between ICSs treatment and pneumonia risk (low-dose: Peto OR, 1.33; 95% CI, 1.22–1.45; medium-dose: Peto OR, 1.50; 95% CI, 1.28–1.76; and high-dose: Peto OR, 1.64; 95% CI, 1.45–1.85). Subgroup analyses based on treatment durations and baseline characteristics (severity, age, and body mass index) of patients were consistant with the above results. Subgroup analysis based on severity of pneumonia showed that fluticasone (Peto OR, 1.75; 95% CI, 1.44–2.14) increased the risk of serious pneumonia, while budesonide and beclomethasone did not. Conclusions: ICSs treatment significantly increased the risk of pneumonia in COPD patients. There was a dose-response relationship between ICSs treatment and pneumonia risk. The pneumonia risk was related with COPD severity.

Abstract
OBJECTIVES It is well established in international literature that respiratory viruses can trigger asthma exacerbations. However, not all viruses affect patients in the same manner and extent. The pandemic of the SARS CoV-2 virus has brought interest to study the association of this novel virus on patients with mild-moderate and severe asthma in terms of susceptibility, severity and treatment. DATA SOURCES – STUDY SELECTION We performed an extensive search of current literature in the databases PubMed, Scopus and Google Scholar for original articles. We decided to include all types of articles, except for case studies, published until the end of February 2021 focusing on the effects of COVID-19 on the respiratory system and the main treatment recommendations up to date for patients with bronchial asthma. RESULTS Until now there is no clear evidence that asthmatics have a higher risk of experiencing exacerbations when infected, nor higher mortality rates than the general population. Nevertheless, our knowledge on molecular pathways behind asthma phenotypes in the past decades is growing, and it underlines the need to predict the unique response each patient may have to infection from the novel coronavirus. It is not clear yet if certain sub-populations of asthmatics are at higher risk than others. CONCLUSION Despite the lack of evidence for higher susceptibility and/or mortality in relation to COVID-19, all asthmatic patients, whether treated with inhaled bronchodilators/corticosteroids or even biologics, should maintain their controller therapy without making any alterations.

Real-world effectiveness of early intervention with fixed-dose tiotropium/olodaterol vs tiotropium in Japanese patients with COPD: a high-dimensional propensity score-matched cohort analysis. Respir Res 2021; 22:180. [PMID: 34140019 PMCID: PMC8212527 DOI: 10.1186/s12931-021-01776-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 06/10/2021] [Indexed: 11/18/2022] Open
Abstract
Background Escalation to triple therapy (long-acting muscarinic antagonist/β2-agonist, inhaled corticosteroid [ICS]) in chronic obstructive pulmonary disorder (COPD) is recommended for patients on LAMA/LABA combinations with frequent exacerbations and severe symptoms. An extended time-to-escalation to triple therapy suggests patients are in a stable condition and is an indicator of treatment effectiveness. No studies in Japanese clinical practice have compared the effectiveness of LAMA/LABA fixed-dose combination therapies with LAMA monotherapy in terms of time-to-escalation to triple therapy. The primary objective of this real-world study in Japan was to compare time-to-escalation to triple therapy among new users of tiotropium/olodaterol or tiotropium monotherapy for COPD without asthma. Methods In this active-comparator cohort study, new users of tiotropium/olodaterol (n = 1436) and tiotropium monotherapy (n = 5352) were identified from a large Japanese hospital-based database (Medical Data Vision Co., Ltd., Tokyo; prespecified study period: 1 April 2015 to 31 March 2019); patients in each group were matched 1:1 using high-dimensional propensity scores (hdPS). The primary outcome was time-to-escalation to triple therapy. Results For the prespecified study period in the hdPS-matched cohort, escalation to triple therapy was infrequent among new users of tiotropium/olodaterol (n = 1302, 7 escalation events) and tiotropium monotherapy (n = 1302, 8 escalation events). The difference in time-to-escalation to triple therapy between groups was not statistically significant (median [interquartile range]: 28 days [15.0–139.2] for tiotropium monotherapy vs 193 days [94.5–302.0] for tiotropium/olodaterol; hazard ratio: 0.89; 95% CI: 0.32–2.46). Similar findings (hazard ratio: 0.71; 95% Cl: 0.36–1.40) were observed in a post hoc analysis, which extended the study period by 1 year to 31 March 2020. Risks of first moderate and/or severe COPD exacerbation were lower for tiotropium/olodaterol than tiotropium monotherapy (between-group differences not significant). There were no significant between-group differences for the risks of all-cause inpatient mortality, major adverse cardiovascular events, and first use of home oxygen therapy. Conclusions ICS monotherapy or ICS/LABA added to tiotropium or tiotropium/olodaterol is limited in Japanese clinical settings. The number of escalations to triple therapy was very limited in the dataset and there was insufficient power to detect differences between the treatment groups in the primary hdPS-matched cohort.

Dual bronchodilator versus inhaled corticosteroid/long-acting β 2-agonist in patients with chronic obstructive pulmonary disease: A meta-analysis of randomized controlled trials. Int Immunopharmacol 2021; 93:107447.

Abstract
BACKGROUND Long-acting muscarinic antagonist/long-acting β2-agonist (LAMA/LABA, also known as dual bronchodilator) and inhaled corticosteroid/LABA (ICS/LABA) are the cornerstone of maintenance treatment for stable chronic obstructive pulmonary disease (COPD) patients. We aimed to comprehensively compare the efficacy and safety of the two maintenance treatment in COPD patients. METHODS We searched the database Embase, Cochrane Library, PubMed, and Clinical Trials.gov systematically (from inception until September 2020). Randomized controlled trials (RCTs) comparing dual bronchodilator with ICS/LABA in the treatment of COPD were included. Efficacy and safety endpoints were pooled as mean differences (MDs) and risk ratios (RRs) with 95% confidence intervals (CIs). This meta-analysis was registered with PROSPERO prospectively # CRD42020203314). RESULTS Fourteen RCTs including 21,496 patients were included. Dual bronchodilator showed a greater improvement in both trough FEV1 (MD = 0.06 L, 95% CI: 0.04-0.07, P < 0.001) and FVC (FVC: MD = 0.12 L, 95% CI: 0.07-0.16, P < 0.001), and a lower risk of pneumonia (RR = 0.62, 95% CI: 0.53-0.72, P < 0.001) in patients with COPD. There were no significant differences neither in the improvement of exacerbations, symptoms, and quality of life, nor in the incidence of cardiovascular events, serious adverse events, all-cause mortality, and withdrawals due to adverse events of treatment between these two maintenance treatments. CONCLUSIONS Dual bronchodilator is superior to ICS/LABA in improving lung function and is associated with a lower risk of pneumonia in patients with COPD. There are no significant differences in other efficacy and safety profiles between these two maintenance treatments.

Abstract
Background Inhaled corticosteroids (ICS) are widely used and recommended to treat chronic obstructive pulmonary disease (COPD). While generally considered safe, several studies demonstrated an increased risk of pneumonia with the use of ICS in COPD patients. Although all ICS indicated for COPD carry the class labeling warning of increased pneumonia risk, evidence suggests an intraclass difference in the risk of pneumonia between inhaled budesonide and fluticasone. To date, systematic reviews of direct-comparison studies have not been performed to assess if an intraclass difference exists. Research Question This review investigated whether there is an intraclass difference in risk of pneumonia between inhaled fluticasone and budesonide, the 2 most commonly used ICS in COPD. Study Design and Methods A search of the medical literature was conducted in PubMed and Embase for the time period of 01/01/69-05/31/19. The search strategy combined terms that defined the patient/disease type, exposures, outcome, and the study/publication type. Descriptive and comparative statistics reported for fluticasone- and budesonide-containing products in each study, including data for pneumonia event subgroups, were extracted and reported by dose, seriousness, or practice setting. Controlled clinical trials and observational studies meeting the inclusion criteria were assessed for methodologic quality by using the appropriate tool from the list of study quality assessment tools developed by the National Institutes of Health. Results The summary relative risk (RR) ratio across 5 included studies (57,199 patients) was 1.13 (95% CI: 1.09-1.19), representing a 13.5% increased risk of pneumonia among fluticasone users compared to budesonide users. Similarly, summary RR ratio for serious pneumonia implied a 14.4% increased risk of serious pneumonia among fluticasone users compared to budesonide users (pooled RR: 1.14; 95% CI: 1.09-1.20). Interpretation There is likely a clinically important intraclass difference in the risk of pneumonia between fluticasone- and budesonide-containing inhaled medications in COPD.

Abstract
BACKGROUND Pneumonia is a major complication leading to death after stroke. The risk factors of pneumonia in convalescent patients who have experienced stroke remain poorly defined. METHODS To identify the risk factors of pneumonia, we applied logistic regression as a statistical method using SPSS23.0 statistical software, based on a sample of 380 patients. And statistical description method was used to analyze pathogens' characteristics and drug resistance. RESULTS Ultimately, the obtained logistic model has statistical significance (χ2(13) = 91.560, P <0.0005). The sensitivity of the model is 41.7%, the specificity is 97.6%, the positive predictive value is 76.9%, and the negative predictive value is 89.8%. The Barthel index (BI) (OR=1.97, 95% CI: 1.01-3.87), basic lung diseases (OR=4.24, 95% CI: 1.02-17.61), trachea ventilation (OR=6.56, 95% CI: 1.18-36.34), feeding tube (OR=6.06, 95% CI: 2.59-14.18), and hypoproteinemia (OR=3.97, 95% CI: 1.56-10.10) were statistically significant (P<0.05). Among patients who have pneumonia, the proportion of gram-positive bacteria, gram-negative bacteria and fungal infection is 10.00%, 54.29%, 5.71% respectively. The study most frequently isolated Pseudomonas aeruginosa (18.57%), followed by Acinetobacter baumannii (10.00%,) and Klebsiella pneumoniae (10.00%). The drug resistance rate of Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae to different antibiotics ranged from 0.00-37.77%, 0.00-85.71% and 0.00-57.14%, respectively. CONCLUSIONS The lower BI scores, basic lung diseases, trachea ventilation, tube feeding, and hypoproteinemia are independent risk factors of pneumonia among convalescent patients with stroke. The main pathogens that caused pneumonia were gram-negative bacteria, and such organisms have different degrees of resistance to drugs.

Abstract
Currently, chronic obstructive pulmonary disease (COPD) patients and their physicians face a number of significant clinical challenges, one of which is the high degree of uncertainty related to chronic bronchial infection (CBI). By reviewing the current literature, several challenges can be identified, which should be considered as goals for research. One of these is to establish the bases for identifying the biological and clinical implications of the presence of potentially pathogenic microorganisms in the airways that should be more clearly elucidated according to the COPD phenotype. Another urgent area of research is the role of long-term preventive antibiotics. Clinical trials need to be carried out with inhaled antibiotic therapy to help clarify the profile of those antibiotics. The role of inhaled corticosteroids in patients with COPD and CBI needs to be studied to instruct the clinical management of these patients. Finally, it should be explored and confirmed whether a suitable antimicrobial treatment during exacerbations may contribute to breaking the vicious circle of CBI in COPD. The present review addresses the current state of the art in these areas to provide evidence which will enable us to progressively plan better healthcare for these patients.

Abstract
The potential detrimental effects of steroids on the immune system to fight viral infections had always been a concern for patients on long term steroids in chronic conditions. A recent warning from WHO on systemic corticosteroid use amid COVID-19 raised suspicion among public and healthcare professionals regarding the safety of steroid use during the SARS-CoV-2 pandemic. The corticosteroids (inhaled and oral) are commonly prescribed in the management of asthma and COPD patients and any unsolicited changes in medications use may lead to potentially severe exacerbations and may risk patient lives. This article provides a critical review of clinical evidence and offers a detailed discussion on the safety and efficacy of corticosteroids in asthma and COPD patients, both with and without COVID-19.

Abstract
In chronic obstructive pulmonary disease (COPD), treatment with inhaled corticosteroids (ICSs) in combination with long acting beta-2-agonists (LABA) or LABA/long-acting muscarinic antagonists (LAMA) is used in order to reduce exacerbations. Treatment with ICS is, however, associated with side effects such as oropharyngeal candidiasis, skin thinning or easy bruising and pneumonia. The aim of this review was to investigate when to use ICS in COPD and to compare the effectiveness and safety of different ICSs. Studies comparing the effect of ICS/LABA and LABA/LAMA on exacerbations have shown divergent results, whereas most studies comparing ICS/LABA/LAMA (triple therapy) with LABA/LAMA have reported fewer exacerbations with triple therapy. Several investigations have shown that the number of eosinophils in blood predicts whether a patient will benefit from treatment with ICS. There is also data indicating that ICS has a small but significant positive effect on lung function decline and decrease mortality. There are four observational studies showing a better effect on exacerbations with budesonide/formoterol than fluticasone propionate/salmeterol and three observational studies showing less risk of pneumonia with budesonide than fluticasone propionate. Studies comparing the effect and safety of other ICSs such as fluticasone furoate and beclomethasone are too few to draw firm conclusions from. In conclusion, ICS together with LABA or LABA/LAMA reduces the risk of exacerbations in COPD. The indication of using ICS in COPD is stronger if the patient has increased blood eosinophils levels. There are data indicating that the choice of ICS matters, with studies showing a better effect-safety profile with budesonide compared to fluticasone propionate whereas it is not possible to make benefit-risk comparisons between the other licensed ICSs.
