Abstract
BACKGROUND In the majority of current therapeutic regimens for chronic obstructive pulmonary disease (COPD), bronchodilators are coupled with inhaled corticosteroids (ICS) to lower the inflammatory response and improve symptoms. This study aims to evaluate the safety of ICS in the treatment of COPD. METHODS Randomized controlled trials related to ICS for COPD that were eligible up to 1 June 2023 were searched in PubMed, EMBASE, and Cochrane. We searched and screened eligible studies for the occurrence of total adverse events, cardiovascular events, upper respiratory tract infections (URTI), pneumonia, oral Candida infections, and musculoskeletal disorders, and finally analyzed them by Review Manager 5.4.1. RESULTS The results showed that ICS increased the incidence of adverse reactions in COPD patients (RR = 1.06, 95% CI: 1.03-1.10, P = .0004); ICS treatment did not increase the risk of cardiovascular events in COPD patients (RR = 0.95, 95% CI: 0.88-1.02, P = .14); ICS increased the incidence of URTI in COPD patients (RR = 1.29, 95% CI: 1.02-1.62, P = .03); ICS increased the incidence of pneumonia in patients with COPD (RR = 2.09, 95% CI: 1.63-2.69, P < .00001); ICS treatment significantly increased the incidence of oral Candida in patients with COPD (RR = 2.96, 95% CI: 1.99-4.41, P < .00001); ICS increased the incidence of musculoskeletal disorders in patients with COPD (RR = 2.87, 95% CI: 1.51-5.45, P = .001). CONCLUSION ICS does not increase the risk of cardiovascular events in patients with COPD, but it does increase the risk of URTI, pneumonia, oral Candida infections, and musculoskeletal disorders in patients with COPD.

Abstract
Both communicable and non-communicable chronic respiratory conditions have accorded for suffering of millions of people of all ages and stated to be leading cause of death, morbidity, economic and social pressures, and disability-adjusted life-years (DALYs) worldwide. These illnesses impair patient's health and negatively impacts families and society, particularly in low and middle-income countries. Chronic respiratory diseases (CRDs) affect different organs of respiratory system, involving airways, parenchyma, and pulmonary vasculature. As the number of respiratory diseases are exponentially escalating but still the stakeholders are not paying attention towards its serious complications. Currently, the treatment being used primarily focusses only on alleviating symptoms of these illness rather delivering the therapeutic agent at target site for optimal care and/or prevention. Lately, extensive research is being conducted on airways and systemic inflammation, oxidative stress, airway, or parenchymal rehabilitation. From which macrophages, neutrophils, and T cells, as well as structural cells as fibroblasts, epithelial, endothelial, and smooth muscle cells have been found to be active participants that are involved in these chronic respiratory diseases. The pathogenesis of all these chronic respiratory diseases gets caused differently via mediators and proteins, including cytokines, chemokines, growth factors and oxidants. Presently, the target of prescription therapies is to reduce the inflammation of airways and relieve the airway contraction. In all studies, cytokines have been found to play an imperative role in fostering chronic airway inflammation and remodelling. Owing to the limitations of conventional treatments, the current review aims to summarize the current knowledge about the chronic respiratory disease and discuss further about the various conventional methods that can be used for treating this ailment. Additionally, it also highlights and discusses about the advanced drug delivery system that are being used for targeting the interleukins for the treatment of CRDs.

Risk of Cardiovascular Events Associated with Inhaled Corticosteroid Treatment in Patients with Chronic Obstructive Pulmonary Disease: A Meta-Analysis. Can Respir J 2018; 2018:7097540. [PMID: 30123392 PMCID: PMC6079461 DOI: 10.1155/2018/7097540] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 06/27/2018] [Indexed: 11/18/2022] Open
Abstract
Background The cardiovascular (CV) safety of inhaled corticosteroids (ICSs) in chronic obstructive pulmonary disease (COPD) is controversial because different studies have suggested that ICSs either increase or reduce the risk of CV events in COPD patients. In this meta-analysis, we assess the CV safety of ICS therapy in COPD. Methods A meta-analysis of randomized, double-blind, parallel-group, placebo-controlled trials of ICS treatment for COPD that include at least 4 weeks of follow-up was performed. A random-effects model was used to evaluate the effects of ICS treatment on CV events. CV events were documented in each trial, and the relative risk (RR) and 95% confidence intervals (CIs) for ICSs were estimated. Results Thirty-one trials were included in this meta-analysis. The risk of CV events was not different between ICS-treated and control groups (RR: 0.99; 95% CI: 0.93 to 1.06; P=0.801). In a subgroup analysis, there were no significant differences in CV events between an ICS combined with long-acting β2 agonist (LABA) (ICS + LABA) group and an LABA-only group (RR: 1.00; 95% CI: 0.90 to 1.10; P=0.930), as well as between a combination group (ICS + LABA) and a long-acting muscarinic antagonist (LAMA) combined with LABA (LAMA + LABA) group (RR: 0.78; 95% CI: 0.39 to 1.55; P=0.473). In addition, there was no difference in the risk of CV events between ICS treatment and control groups (RR: 0.99; 95% CI: 0.90 to 1.09; P=0.872). Conclusions These results demonstrate that ICSs do not increase the risk of CV events in COPD patients.

Abstract
Inhaled formoterol is a long-acting selective beta2-adrenoceptor agonist, with an onset of action of 5 minutes postdose and a bronchodilator effect that lasts for at least 12 hours. Statistically significant and clinically relevant (>120 ml) improvements in lung function [assessed using standardized/normalized area under the forced expiratory volume in 1 second (FEV1) versus time curve (AUC FEV1)] were observed with inhaled formoterol 12 microg twice daily (the approved dosage in the US) compared with placebo in 12-week and 12-month, randomized, double-blind trials in patients with chronic obstructive pulmonary disease (COPD). The bronchodilator efficacy of formoterol 12 microg twice daily was greater than that of oral slow-release theophylline (individualized dosages) in a 12-month trial or inhaled ipratropium bromide 40 microg four times daily in a 12-week trial. Improvement in AUC FEV1 with formoterol, but not theophylline, compared with placebo was observed in patients with irreversible or poorly-reversible airflow obstruction. Formoterol also significantly improved health-related quality of life compared with ipratropium bromide or placebo and significantly reduced symptoms compared with placebo. Combination therapy with formoterol 12 microg twice daily plus ipratropium bromide 40 microg four times daily was significantly more effective than albuterol (salbutamol) 200 microg four times daily plus the same dosage of ipratropium bromide in a 3-week, randomized, double-blind, double-dummy, crossover trial. Inhaled formoterol was well tolerated in clinical trials. The incidence of investigator-determined drug-related adverse events with inhaled formoterol 12 microg twice daily was similar to that with placebo and inhaled ipratropium bromide 40 microg four times daily but lower than that with oral slow-release theophylline (individualized dosages). Importantly, there were no significant differences between formoterol and placebo or comparator drugs in cardiovascular adverse events in patients with COPD and corrected QT interval values within the normal range. In conclusion, inhaled formoterol improved lung function and health-related quality of life and reduced symptoms relative to placebo in clinical trials in patients with COPD. The drug had greater bronchodilator efficacy than oral slow-release theophylline or inhaled ipratropium bromide and showed efficacy in combination with ipratropium bromide. The adverse events profile (including cardiovascular adverse events) with formoterol was similar to that with placebo. Thus, inhaled formoterol may be considered as a first-line option for the management of bronchoconstriction in patients with COPD who require regular bronchodilator therapy for the management of symptoms.

Abstract
BACKGROUND The role of inhaled corticosteroids (ICS) in chronic obstructive pulmonary disease (COPD) has been the subject of much controversy. Major international guidelines recommend selective use of ICS. Recently published meta-analyses have reported conflicting findings on the effects of inhaled steroid therapy in COPD. OBJECTIVES To determine the efficacy and safety of inhaled corticosteroids in stable patients with COPD, in terms of objective and subjective outcomes. SEARCH METHODS A pre-defined search strategy was used to search the Cochrane Airways Group Specialised Register for relevant literature. Searches are current as of July 2011. SELECTION CRITERIA We included randomised trials comparing any dose of any type of inhaled steroid with a placebo control in patients with COPD. Acute bronchodilator reversibility to short-term beta(2)-agonists and bronchial hyper-responsiveness were not exclusion criteria. The a priori primary outcome was change in lung function. We also analysed data on mortality, exacerbations, quality of life and symptoms, rescue bronchodilator use, exercise capacity, biomarkers and safety. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We collected adverse effects information from the trials. MAIN RESULTS Fifty-five primary studies with 16,154 participants met the inclusion criteria. Long-term use of ICS (more than six months) did not consistently reduce the rate of decline in forced expiratory volume in one second (FEV(1)) in COPD patients (generic inverse variance analysis: mean difference (MD) 5.80 mL/year with ICS over placebo, 95% confidence interval (CI) -0.28 to 11.88, 2333 participants; pooled means analysis: 6.88 mL/year, 95% CI 1.80 to 11.96, 4823 participants), although one major trial demonstrated a statistically significant difference. There was no statistically significant effect on mortality in COPD patients (odds ratio (OR) 0.98, 95% CI 0.83 to 1.16, 8390 participants). Long-term use of ICS reduced the mean rate of exacerbations in those studies where pooling of data was possible (generic inverse variance analysis: MD -0.26 exacerbations per patient per year, 95% CI -0.37 to -0.14, 2586 participants; pooled means analysis: MD -0.19 exacerbations per patient per year, 95% CI -0.30 to -0.08, 2253 participants). 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, 2507 participants). Response to ICS was not predicted by oral steroid response, bronchodilator reversibility or bronchial hyper-responsiveness in COPD patients. There was an increased risk of oropharyngeal candidiasis (OR 2.65, 95% CI 2.03 to 3.46, 5586 participants) and hoarseness. 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 1.56, 95% CI 1.30 to 1.86, 6235 participants). The long-term studies that measured bone effects generally showed no major effect on fractures and bone mineral density over three years. AUTHORS' CONCLUSIONS Patients and clinicians should balance the potential benefits of inhaled steroids in COPD (reduced rate of exacerbations, reduced rate of decline in quality of life and possibly reduced rate of decline in FEV(1)) against the potential side effects (oropharyngeal candidiasis and hoarseness, and risk of pneumonia).

Abstract
INTRODUCTION A modified prescription-event monitoring (PEM) study was conducted to examine the safety of the introduction of the metered dose inhaler (MDI) Flixotide Evohaler (fluticasone with the propellant HFA 134a). METHODS Patients were identified from the first NHS prescriptions dispensed in England for Flixotide Evohaler. Postal questionnaires were sent to the prescribing doctor, requesting information including: demographic characteristics, severity of indication, concomitant medication, event data 3 months prior to and 3 months after the first prescription, and any reasons for stopping Flixotide. Pregnancies, deaths and selected events were followed up. Incidence density ratios (IDRs) were calculated to compare event rates 3 months before and 3 months after the introduction of Flixotide Evohaler. RESULTS The cohort comprised 13 413 patients that were prescribed Flixotide Evohaler. The response rate was 64.0%. When the pre- and post-exposure periods were compared fewer patients had events in the post-exposure period, and there was no significant difference in the length of courses of oral steroid use. Eighteen patients experienced an event within 1 hour of using Flixotide Evohaler; these were minor with the exception of one case of angioneurotic facial oedema. Six of these events were assessed as possibly related to Flixotide Evohaler. During the study period there were an additional 13 patients with events assessed as possibly related to Flixotide Evohaler, including two reports of allergic reactions. DISCUSSION The results suggest that the transition to Flixotide Evohaler was generally well tolerated. The modified methodology has contributed to the risk management of the introduction of this product.

Major international guidelines recommend selective use of ICS. Recently published meta-analyses have reported conflicting findings on the effects of inhaled steroid therapy in COPD. OBJECTIVES The objective of the review is to determine the efficacy of regular use of inhaled corticosteroids in patients with stable COPD. SEARCH STRATEGY A pre-defined search strategy was used to search the Cochrane Airways Group specialised register for relevant literature. Searches are current as of October 2006. SELECTION CRITERIA We selected randomised trials comparing any dose of any type of inhaled steroid with a placebo control in patients with COPD.

DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Forty-seven primary studies with 13,139 participants met the inclusion criteria. Medium term use of ICS (> two months and up to six months) resulted in a small improvement in FEV1 in some studies. Long term use of ICS (> six months) did not significantly reduce the rate of decline in FEV1 in COPD patients (weighted mean difference (WMD) 5.80 ml/year with ICS over placebo, 95% CI -0.28 to 11.88, 2333 participants). There was no statistically significant effect on mortality in COPD patients (OR 0.98, 95% CI 0.83 to 1.16, 8390 participants).

There was an increased risk of oropharyngeal candidiasis (OR 2.49, 95% CI 1.78 to 3.49, 4380 participants) and hoarseness. The few long term studies that measured bone effects generally showed no major effect on fractures and bone mineral density over 3 years. AUTHORS' CONCLUSIONS Patients and clinicians should balance the potential benefits of inhaled steroids in COPD (reduced rate of exacerbations, reduced rate of decline in quality of life), against the known increase in local side effects (oropharyngeal candidiasis and hoarseness). The risk of long term adverse effects is unknown.

Abstract
Parkinson's disease (PD) affects one in every 100 persons above the age of 65 years, making it the second most common neurodegenerative disease after Alzheimer's disease. PD is a disease of the central nervous system that leads to severe difficulties with body motions. The currently available therapies aim to improve the functional capacity of the patient for as long as possible; however they do not modify the progression of the neurodegenerative process. The need for newer and more effective agents is consequently receiving a great deal of attention and consequently being subjected to extensive research. This review concisely compiles the limitations of currently available therapies and the most recent research regarding neuroprotective agents, antioxidants, stem cell research, vaccines and various surgical techniques available and being developed for the management of PD.

Abstract
OBJECTIVE To examine nonvertebral fracture risk in relation to inhaled corticosteroid (ICS) exposure among adults with respiratory disease. DESIGN AND PATIENTS Nested case-control study within a cohort of 89,877 UnitedHealthcare members aged > or = 40 years with physician insurance claims for COPD or asthma, enrolled for > or = 1 year from January 1, 1997 to June 30, 2001. METHODS Cases (n = 1,722) represented patients with a first treated nonvertebral fracture (the index date is the first fracture claim). Control subjects (n = 17,220) were randomly selected from the person-time and assigned a random index date. ICS exposure was ascertained 1 month, 3 months, 6 months, and 12 months before the index date, with estimated cumulative dose through 0 to 6 months, 7 to 12 months, and 0 to 12 months. Covariates included demographics, oral corticosteroid and other medication exposure, comorbidities, and indicators of respiratory disease severity. Odds ratios (ORs) adjusted for all covariates were estimated by logistic regression. RESULTS No increased fracture risk with ICS exposure as a class or with fluticasone propionate alone was detected. ORs for exposure in the preceding 30 days were 1.05 (95% confidence interval [CI], 0.89 to 1.24), 1.13 (95% CI, 0.90 to 1.40), and 0.97 (95% CI, 0.78 to 1.21) for all ICS, fluticasone propionate, and other ICS, respectively. No dose-response effect was present. Among patients with COPD only (n = 6,932), no increased risk was found for recent ICS exposure (OR, 0.86; 95% CI, 0.59 to 1.25). CONCLUSIONS Concern about nonvertebral fracture risk should not strongly influence the decision to use recommended doses of ICS for adult patients with asthma or COPD in managed-care settings in the United States. This study could not evaluate very-high ICS dose, long-term ICS exposure, or vertebral fracture risk.

Abstract
This article reviews available data on the drug therapy armamentarium for the acute exacerbation of chronic obstructive pulmonary disease (COPD). Summaries of studies and therapeutic issues for bronchodilators, antibiotic therapy, corticosteroid use, and a few miscellaneous agents are presented. Many controversies exist in the criteria defining the acute exacerbation, in defining appropriate outcome parameters for assessment, and, consequently, in developing specific consistent recommendations for drug therapy. Five published guidelines assist the clinician in therapeutic drug management of the acute exacerbation of COPD, and each differs in its recommendations for drug therapy prescription. The article includes synopses for drug therapy recommendations from the guidelines.

Abstract
BACKGROUND The impact of long-term inhaled corticosteroid (ICS) therapy on bone mineral density (BMD) is poorly understood. OBJECTIVE To evaluate the impact of long-term ICS use on BMD. METHODS Random-effects meta-analysis. Published and unpublished literature were identified by searches of MEDLINE and EMBASE databases and consultation with experts. Studies reporting BMD among adult asthma and chronic obstructive pulmonary disease (COPD) patients using ICS and non-ICS controls were identified. Studies selected for review included at least 1 year of follow-up. Two independent reviewers evaluated studies; data from those meeting specified inclusion criteria were abstracted for inclusion in the meta-analysis. RESULTS Fourteen (5.3%) of 266 reviewed studies met specified inclusion criteria. Sufficient data were available to perform meta-analysis on 3 measures for ICS-using patients (lumbar, femoral neck, and major trochanter BMD) and 1 measure (lumbar BMD) for non-ICS-using controls. Using current National Asthma Education and Prevention Program definitions, the majority of studies (12 of 14) included patients receiving moderate to high doses of ICSs. Among ICS users, annual changes from baseline in lumbar, femoral neck, and major trochanter BMD (-0.23%, -0.17%, and +1.46%, respectively) were not statistically significant. Mean changes in lumbar BMD were also not significantly different from controls (-0.02%). Further, annual changes in lumbar BMD were not statistically significant for subgroups of patients with asthma or COPD. CONCLUSIONS Long-term use of ICSs in patients with asthma or COPD was not associated with significant changes in BMD.

BACKGROUND During the last decades, there has been increased concern about the association between oral corticosteroid (OC) therapy and osteoporosis. OBJECTIVE The question currently discussed is whether inhaled corticosteroids (ICs) in recommended doses have any clinically relevant effects on bone mineral density (BMD). METHODS We compared BMD in postmenopausal women exposed to corticosteroids only in inhaled form (IC group, n = 106) with that in women not exposed to corticosteroids (unexposed group, n = 674). BMD was also studied in 49 women exposed to OCs, intra-articular injections, or both in addition to ICs (OC group). The women were recruited from a population-based prospective cohort study. METHODS We used a dietary survey, bone density measurement of the forearm, and a health questionnaire including an interview about past and present medication use. RESULTS Mean BMD did not significantly differ between the IC group (0.434 g/cm2) and the unexposed group (0.429 g/cm2). The mean duration and dose of ICs was 8.2 +/- 5.03 years and 853 microg daily. Within the IC group, BMD stratified for cumulative dose of IC, duration, or current dose greater than or less than 1000 microg did not differ. BMD in the OC group was lower than that in the IC group (0.408 vs 0.434 g/cm2). CONCLUSION No difference in BMD was noted between the IC group and unexposed control subjects, nor was any dose-response relationship observed between IC therapy and BMD.
