Abstract
The prevalence of asthma among the elderly population has witnessed a notable rise, presenting unique challenges in diagnosis and management. Biologic therapies, such as omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, and tezepelumab, have demonstrated efficacy in targeting specific pathways associated with severe asthma in elderly individuals. However, a significant research gap exists in the application of these therapies in elderly asthma patients. Despite the considerable size of the elderly asthma population and the social and economic burden that this specific demographic imposes on society, the available body of research catering to this group is limited. Notably, no RCTs have been expressly designed for the elderly across all asthma biologic therapies. Moreover, most RCTs have set upper age cutoffs, commonly 75 years old, and exclusion criteria for common comorbidities in the elderly, thus marginalizing this group from pivotal research. This underscores the crucial need for intentional inclusion of elderly participants in separately designed clinical trials and more researches, aiming to augment the generalizability of findings and enhance therapeutic outcomes. Given the distinct physiological changes associated with aging, there may be a concern regarding the efficacy and safety of biologic therapies in the elderly compared to non-elderly adults, posing a barrier to their use in this population. However, observational studies have shown similar benefits of these therapies in elderly individuals as seen in non-elderly adults. Other anticipated challenges related to initiating biologic therapy in elderly people with asthma including dosing consideration and monitoring strategies, which are important areas of investigation for optimizing asthma management will be discussed in this review. In summary, this review navigates the current landscape of biologic therapies for elderly asthma, offering valuable insights for various stakeholders, including researchers, healthcare providers, and policymakers, to advance asthma care in this vulnerable population. We propose that future research should concentrate on tailored, evidence-based approaches to address the undertreatment of elderly asthma patients.

Abstract
Glucocorticoids (GCs) are widely used by several specialties for the treatment of a variety of diseases and conditions. The unfavorable effect of oral GCs on bone health is well-documented. The ensuing from their use glucocorticoid-induced osteoporosis (GIOP) is the most common cause of medication-induced osteoporosis and fractures. It is uncertain, however, if, and in what extent, GCs administered by other routes affect the skeleton. In the present review, we quote current evidence on the effect of inhaled GCs, epidural and intra-articular steroid injections, and topical GCs on bone outcomes. Although evidence is limited and weak, it seems that a small proportion of the administered GCs may be absorbed, enter the systemic circulation, and adversely affect the skeleton. Potent GCs, higher doses, and longer treatment duration seem to infer the greater risk for bone loss and fractures. There are scarce data, and only for inhaled GCs, regarding the efficacy of antiosteoporotic medications in patients receiving GCs through routes other than oral. Further studies are needed to clarify the relationship between GC administration through these routes and bone outcomes and to help establishing guidelines for the optimal management of such patients.

Abstract
The widespread use of glucocorticoids (GCs) contributes to the effective management of several diseases and conditions. However, it comes at a price in the case of the bones causing glucocorticoid-induced osteoporosis (GIOP), the most common cause of secondary osteoporosis and fractures. Several scientific societies have issued comprehensive guidelines on the optimal management of patients receiving GCs with the aim of providing answers to three fundamental questions, namely, whom to treat, when to treat, and how to treat. Both common ground and different approaches exist among them. General preventive measures should start along with GC initiation, and the duration of GC therapy should be limited to the minimal effective range. A pre-existing fracture, age, gender, menopausal status, dose, and duration of GC treatment are key factors in the decision to initiate antiosteoporotic medication. Oral bisphosphonates are typically regarded as the first-line treatment choice for GIOP partly due to their cost-effectiveness. Denosumab is another valid option, but an "exit strategy" should be considered before its initiation due to the risk of rebound-associated vertebral fractures upon its discontinuation. Since impaired bone formation represents the main mechanism by which GCs negatively affect skeletal health, osteoanabolic therapies appear to be pathophysiologically the more appropriate and appealing option, although cost considerations currently limit their use to selected severe cases. Regardless of the agent selected to mitigate the impact of GCs on the skeleton, what is most crucial is that the treating physician correctly stratifies the risk and intervenes at the right time.

Abstract
Chronic inflammatory respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis, present ongoing challenges in terms of effective treatment and management. These diseases are characterized by persistent inflammation in the airways, leading to structural changes and compromised lung function. There are several treatments available for them, such as bronchodilators, immunomodulators, and oxygen therapy. However, there are still some shortcomings in the effectiveness and side effects of drugs. To achieve optimal therapeutic outcomes while minimizing systemic side effects, targeted therapies and precise drug delivery systems are crucial to the management of these diseases. This comprehensive review focuses on the role of drug delivery systems in chronic inflammatory respiratory diseases, particularly nanoparticle-based drug delivery systems, inhaled corticosteroids (ICSs), novel biologicals, gene therapy, and personalized medicine. By examining the latest advancements and strategies in these areas, we aim to provide a thorough understanding of the current landscape and future prospects for improving treatment outcomes in these challenging conditions.

Abstract
Nintedanib is a tyrosine kinase inhibitor of fibroblast growth factor-, vascular endothelial growth factor-, and platelet-derived growth factor receptors. These three receptors promote new blood vessel formation and maintenance, which is essential for tumor growth and spread. Several trials have shown that nintedanib plays a substantial role in treating patients with non-small cell lung cancer (NSCLC) and idiopathic pulmonary fibrosis. Recently, several clinical trials of nintedanib to treat NSCLC have been reported. In this review, we focus on our current understanding of nintedanib treatment for advanced NSCLC patients and summarize the literature on using nintedanib in radiation-induced lung toxicity and the efficacy and tolerability of nintedanib.

Syst Rev 2023; 12:131. [PMID: 37525235 PMCID: PMC10388527 DOI: 10.1186/s13643-023-02289-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2022] [Accepted: 07/14/2023] [Indexed: 08/02/2023] Open
Abstract
BACKGROUND Overviews (i.e., systematic reviews of systematic reviews, meta-reviews, umbrella reviews) are a relatively new type of evidence synthesis. Among others, one reason to conduct an overview is to investigate adverse events (AEs) associated with a healthcare intervention. Overviews aim to provide easily accessible information for healthcare decision-makers including clinicians. We aimed to evaluate the clinical utility of overviews investigating AEs. METHODS We used a sample of 27 overviews exclusively investigating drug-related adverse events published until 2021 identified in a prior project. We defined clinical utility as the extent to which overviews are perceived to be useful in clinical practice. Each included overview was assigned to one of seven pharmacological experts with expertise on the topic of the overview. The clinical utility and value of these overviews were determined using a self-developed assessment tool. This included four open-ended questions and a ranking of three clinical utility statements completed by clinicians. We calculated frequencies for the ranked clinical utility statements and coded the answers to the open-ended questions using an inductive approach. RESULTS The overall agreement with the provided statements was high. According to the assessments, 67% of the included overviews generated new knowledge. In 93% of the assessments, the overviews were found to add value to the existing literature. The overviews were rated as more useful than the individual included systematic reviews (SRs) in 85% of the assessments. The answers to the open-ended questions revealed two key aspects of clinical utility in the included overviews. Firstly, it was considered useful that they provide a summary of available evidence (e.g., along with additional assessments, or across different populations, or in different settings that have not been evaluated together in the included SRs). Secondly, it was found useful if overviews conducted a new meta-analysis to answer specific research questions that had not been answered previously. CONCLUSIONS Overviews on drug-related AEs are considered valuable for clinical practice by clinicians. They can make available evidence on AEs more accessible and provide a comprehensive view of available evidence. As the role of overviews evolves, investigations such as this can identify areas of value.

Abstract
OBJECTIVES To investigate reporting and methodological characteristics of overviews on adverse (drug-associated) events (AEs) of pharmacological interventions. STUDY DESIGN AND SETTING We searched MEDLINE, Embase, Epistemonikos, and the Cochrane Database of Systematic Reviews from inception to May 17, 2021 for overviews exclusively investigating AEs of pharmacological interventions. We extracted general, reporting, and methodological characteristics and analyzed data descriptively. RESULTS We included 27 overviews, 70% of which were published in 2016 or later. The most common nomenclature in the title was "overview" (56%), followed by "umbrella review" (26%). The median number of included systematic reviews (SRs) in each overview was 15 (interquartile range 7-34). Study selection methods were reported in 52%, methods for data extraction in 67%, and methods for critical appraisal in 63% of overviews. An assessment of methodological quality of included SRs was performed in 70% of overviews. Only 22% of overviews reported strategies for dealing with overlapping SRs. An assessment of the certainty of the evidence was performed in 33% of overviews. CONCLUSION To ensure methodological rigor, authors of overviews on AEs should follow available guidance for the conduct and reporting of overviews.

Abstract
OBJECTIVES This systematic review aimed to discuss the prevalence and the risk factors of the musculoskeletal pain in chronic obstructive pulmonary disease (COPD). DATA SOURCE AND STUDY SELECTION Four databases were analysed (Scopus, PubMed, Cochrane and EMBASE). We excluded systematic reviews, meta-analyses, conference abstracts and case reports. Two authors independently checked for the eligibility of the relevant articles. The risk of bias was evaluated using the Newcastle Ottawa Quality Assessment Scale and the Joanna Briggs Institute critical appraisal checklist. The selection and evaluation of studies followed the PRISMA guidelines. RESULTS Twenty studies were retrieved, including from 21 to 7952 patients with COPD. The prevalence of pain was highly heterogeneous across studies: 7-89.7%. Pain was mostly reported in the lumbar (7-69%) and cervical spine (11-48.3%) and the chest (44-82.8%). The main risk factors for developing pain were old age, sex (female), level of physical activity (low) and comorbidities. CONCLUSION Pain is a very common symptom in patients with COPD. Despite this, few clinical trials have investigated the pain. It appears to be located primarily in the lumbar, cervical and thoracic regions and facilitated by being a female, a low level of physical activity, comorbidity(ies) and old age.

Abstract
Chronic inflammation induces proinflammatory cytokine cascades. In addition to systemic inflammation, hypoxemia, hypercapnia, a catabolic metabolism, gonadal or thyroid dysfunction, musculoskeletal dysfunction and inactivity as well as vitamin D deficiency contribute to an increased risk of fragility fractures. Iatrogenic causes of osteoporosis are long-term use of inhaled or systemic glucocorticoids (GC). Inhalative GC application in asthma is often indicated in childhood and adolescence, but interstitial lung diseases such as chronic organizing pneumonia, COPD, sarcoid or rheumatic diseases with lung involvement are also treated with inhalative or oral GC. In patients with cystic fibrosis, malabsorption in the context of pancreatic insufficiency, hypogonadism and chronic inflammation with increased bone resorption lead to a decrease in bone structure. After lung transplantation, immunosuppression with GC is a risk factor.The underlying pneumological diseases lead to a change in the trabecular and cortical bone microarchitecture and to a reduction in osteological formation and resorption markers. Hypercapnia, acidosis and vitamin D deficiency can accelerate this process and thus increase the individual risk of osteoporotic fragility fractures.A bone mineral density measurement with a T‑Score < -2.5 is a threshold value for the diagnosis of osteoporosis; in contrast the vast majority of all osteoporotic fractures occur with a T‑Score > -2.5. A history of low-trauma fracture indicates osteological therapy.All antiresorptive or anabolic drugs approved in Austria for the treatment of osteoporosis are also indicated for pneumological patients with an increased fragility fracture risk of bone fractures in accordance with the national reimbursement criteria.

Abstract
PURPOSE OF REVIEW Chronic obstructive pulmonary disease (COPD) imposes a large burden on the global population and even more so for the elderly who face significant obstacles in the diagnosis, management, and psychosocial effects of the disease. This review describes the current challenges and key points in the management of COPD in the elderly. RECENT FINDINGS Lower limit rather than fixed cut off of the FEV1/FVC ratio can improve the diagnosis and better predict COPD mortality. High relative to standard dose influenza vaccination reduces confirmed cases of influenza overall and reduces hospitalizations in older nursing home residents. Simple interventions that include electronic health record tracking can significantly improve vaccination rates. Although many inhaler and nebulized medications are available for the elderly, the final regimen is usually determined by a combination of expense, issues with proper device use (from difficulty with coordination, hand grip, inspiratory flows or cognitive function) and the side effect profile. Fortunately, the switch to cheaper or better covered alternatives can be well tolerated with improvement in adherence and exacerbations of COPD. Finally, caution should be made against ageism, which may be a factor in the recommendation of rehabilitation or palliative care in the elderly COPD patient, as both are underused despite evidence of benefit. SUMMARY Although care for the elderly COPD patient can be difficult, we summarize key points that the physician should be cognizant of to provide comprehensive care.

Abstract
BACKGROUND This meta-analysis aimed to systematically estimate the prevalence of comorbid bronchiectasis in patients with asthma and to summarize its clinical impact. METHODS Embase, PubMed, and Cochrane Library electronic databases were searched to identify relevant studies published from inception until March 2020. STUDY SELECTION Studies were included if bronchiectasis was identified by high-resolution computed tomography. Outcomes included the prevalence of bronchiectasis and its association with demographic characteristics and indicators of asthma severity, including results of lung function tests and the number of exacerbations. RESULTS Five observational studies with 839 patients were included. Overall, the mean prevalence of bronchiectasis in patients with asthma was 36.6% (307/839). Patients with comorbid bronchiectasis had lower forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) (MD: -2.71; 95% CI: -3.72 to -1.69) and more frequent exacerbations (MD: 0.68; 95% CI: 0.03 to 1.33) than those with asthma alone, and there was no significant difference of sex, duration of asthma and serum levels of immunoglobulin(Ig)Es between asthmatic patients with or without bronchiectasis. CONCLUSION The presence of bronchiectasis in patients with asthma was associated with greater asthma severity. There are important therapeutic implications of identifying bronchiectasis in asthmatic patients.

[PMID: 33268342 PMCID: PMC7713222 DOI: 10.1136/bmjresp-2020-000756] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 10/08/2020] [Accepted: 10/19/2020] [Indexed: 12/17/2022] Open
Abstract
Background Oral corticosteroid use increases the risk of systemic adverse effects including osteoporosis, bone fractures, diabetes, ocular disorders and respiratory infections. We sought to understand if inhaled corticosteroid (ICS) use in asthma is also associated with increased risk of systemic effects. Methods MEDLINE and Embase databases were searched to identify studies that were designed to investigate ICS-related systemic adverse effects in people with asthma. Studies were grouped by outcome: bone mineral density (BMD), respiratory infection (pneumonia or mycobacterial infection), diabetes and ocular disorder (glaucoma or cataracts). Study information was extracted using the PICO checklist. Risk of bias was assessed using the Cochrane Risk of Bias tool (randomised controlled trials) and Risk of Bias In Non-randomised Studies of Interventions-I tool (observational studies). A narrative synthesis was carried out due to the low number of studies reporting each outcome. Results Thirteen studies met the inclusion criteria, 2 trials and 11 observational studies. Study numbers by outcome were: six BMD, six respiratory infections (four pneumonia, one tuberculosis (TB), one non-TB mycobacteria), one ocular disorder (cataracts) and no diabetes. BMD studies found conflicting results (three found loss of BMD and three found no loss), but were limited by study size, short follow-up and lack of generalisability. Studies addressing infection risk generally found positive associations but suffered from a lack of power, misclassification and selection bias. The one study which assessed ocular disorders found an increased risk of cataracts. Most studies were not able to fully adjust for known confounders, including oral corticosteroids. Conclusion There is a paucity of studies assessing systemic adverse effects associated with ICS use in asthma. Those studies that have been carried out present conflicting findings and are limited by multiple biases and residual confounding. Further appropriately designed studies are needed to quantify the magnitude of the risk for ICS-related systemic effects in people with asthma.

Abstract
OBJECTIVE To determine if the use of inhaled corticosteroid (ICS) therapy affects glycemic control in patients with chronic obstructive pulmonary disease (COPD) and type 2 diabetes mellitus (T2DM). BACKGROUND Studies have shown mixed evidence on the association between ICS use and worsening glycemic control in patients with preexisting diabetes. METHODS Data were recorded from electronic medical records of veteran patients aged 18 to 80 with COPD and T2DM on at least 2 oral antiglycemic medications from January 1, 2000, to December 31, 2017, at the Veterans Affairs (VA) North Texas Health Care System (VANTHCS). The primary outcome was the rate of A1c progression >10% at 12 months and 5 years. RESULTS This study included 127 (64 in the ICS group and 63 in the non-ICS group) patients; baseline characteristics between groups were similar with the exception of age and tobacco use. No statistically significant difference was found between groups with regard to the primary outcome. More patients in the non-ICS group had antiglycemic medications initiated at 12 months (P = .009) and 5 years (P = .003) compared to the ICS group. CONCLUSION Inhaled corticosteroids did not negatively impact glycemic control among veterans with comorbid COPD and T2DM.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is associated with multiple comorbidities, which impact negatively on patients and are often underdiagnosed, thus lacking a proper management due to the absence of clear guidelines. Purpose To elaborate expert recommendations aimed to help healthcare professionals to provide the right care for treating COPD patients with comorbidities. Methods A modified RAND-UCLA appropriateness method consisting of nominal groups to draw up consensus recommendations (6 Spanish experts) and 2-Delphi rounds to validate them (23 Spanish experts) was performed. Results A panel of Spanish internal medicine experts reached consensus on 73 recommendations and 81 conclusions on the clinical consequences of the presence of comorbidities. In general, the experts reached consensus on the issues raised with regard to cardiovascular comorbidity and metabolic disorders. Consensus was reached on the use of selective serotonin reuptake inhibitors in cases of depression and the usefulness of referring patients with anxiety to respiratory rehabilitation programmes. The results also showed consensus on the usefulness of investigating the quality of sleep, the treatment of pain with opioids and the evaluation of osteoporosis by lateral chest radiography. Conclusion This study provides conclusions and recommendations that are intended to improve the management of the complexity of patients with COPD and important comorbidities, usually excluded from clinical trials.

Abstract
PURPOSE OF REVIEW The presence of bronchiectasis has been described in about 30% of severe asthma patients. The coexistence of these two respiratory conditions poses new challenges from both clinical and research perspectives. We will review the available literature on this topic to discuss the existance of a specific clinical phenotype of asthma. RECENT FINDINGS Despite the paucity of literature, the presence of bronchiectasis with severe asthma is associated with older age, chronic bronchial expectoration, rhinosinusitis, more frequent and severe exacerbations, neutrophilic airway inflammation and poor response to usual treatment. Conversely, asthma features are also described in bronchiectasis patients even in the absence of an appropriate diagnosis of asthma. In both cases, there is some evidence supporting the use of bronchodilators, macrolides and respiratory physiotherapy, while the use of inhaled corticosteroids and antibiotics is controversial. SUMMARY Based on available evidence on the association between (severe) asthma and bronchiectasis, its pathophysiology, certain clinical aspects and prognosis are largely unclear. Although specific management appears to be required in most cases, in our opinion there is still insufficient evidence to consider it a distinct phenotype of severe asthma. Hopefully, future research will shed more light on this topic and define the best therapeutic approach.

Abstract
CONTEXT Epidural steroid injections (ESIs) are a common, effective treatment of lumbar radiculopathy and sciatica. Although the negative skeletal effects of oral glucocorticoids are well established, little is known about the impact of ESI on bone quality. OBJECTIVE To investigate the relationship between ESI exposure and volumetric bone mineral density (vBMD) at the lumbar spine (LS) using central quantitative CT. DESIGN Retrospective study. SETTING University hospital outpatient facility. PATIENTS All patients had CT scans of the LS between 2011 and 2016. Cases received at least three ESIs prior to the date of CT (n = 121). Controls were matched for age and sex (n = 121). MAIN OUTCOME MEASURES Cumulative ESI dose was calculated. vBMD was measured at T12 through L5 using QCT Pro phantomless software (MindWays). RESULTS Mean age of subjects was 65 ± 14 years, and 49% were women. Median number of ESIs was 4 (range: 3 to 16). Median cumulative ESI dosage was 340 mg of triamcinolone or equivalent (range: 150 to 1400 mg). Compared with controls, ESI subjects had lower vBMD at each vertebral level. Higher cumulative dose was associated with lower mean vBMD at T12 to L5 (r = -0.22, P = 0.02). CONCLUSIONS Greater cumulative ESI dose was related to lower vBMD at the LS. To our knowledge, this is the first study to measure vBMD in patients treated with ESIs. Prospective studies are needed to confirm these findings and to help identify the best strategies for preventing bone loss in this population.

Abstract
Objective: This study aims to systematically evaluate the efficacy and safety of catgut implantation at acupoints (CIA) treating asthma, extracting data from the published clinical trials. Methods: The Cochrane Library, PubMed, Chinese Biomedical Database (CBM), CNKI, WANFANG and VIP databases were searched up to February 2017. Randomized controlled trials (RCTs) involving CIA or CIA plus conventional medicine treatment (CMT) were selected with CMT as control. We assessed the methodological quality of RCTs using the Cochrane Handbook for Systematic Review of Interventions. The outcome data of trials were analyzed using RevMan5.3. Results: A total of 12 studies ([Formula: see text]) were included. Most of the included studies were assessed to have high risk of bias with low quality of methodology. CIA application significantly improved the overall therapeutic efficacy ([Formula: see text]) and pulmonary function (forced expiratory volume in 1[Formula: see text]s (FEV1) and FEV1%, [Formula: see text] and [Formula: see text]) and reduced the overall scores of TCM symptoms ([Formula: see text]). Further, it significantly relieved several TCM symptoms including shortness of breath, chest distress and cough ([Formula: see text]). However, CIA only exerted a protective tendency for expectoration and wheezing without significant difference and had no effects on recurrence rate (all [Formula: see text]). Conclusions: CIA treatment could improve the overall efficacy and pulmonary function and relief several symptoms. However, the evidence remains weak. Rigorous and larger trials will be the basis of the effectiveness and long-term effects of CIA therapies.

Abstract
: Chronic obstructive pulmonary disease (COPD) is a prevalent and disabling disorder in the United States, especially affecting older individuals, women, and those with a history of smoking. Studies show that COPD may be underrepresented, underdiagnosed, and undertreated in elderly patients residing in long-term care (LTC) facilities. The quality of care for LTC residents with COPD is heterogeneous in regard to both the facility and the patient. For LTC facilities, care should be driven by staff education, interstaff communication, and interfacility communication. From the perspective of the LTC patient, choice of medication and device should be based on appropriate diagnosis, comorbidities, ability to perform treatment, and patient preferences. Nebulization is currently underutilized in LTC settings, although it would benefit older patients with low peak inspiratory flow, cognitive impairment, and/or physical impairment, which may preclude them from using other inhalation devices. Authors developed a COPD treatment algorithm that focuses on three primary patient aspects to consider when deciding on respiratory device in patients in LTC facilities: inspiratory flow, hand dexterity and coordination, and cognitive capacity.

Abstract
The most effective anti-inflammatory drugs used to treat patients with airways disease are topical glucocorticosteroids (GCs). These act on virtually all cells within the airway to suppress airway inflammation or prevent the recruitment of inflammatory cells into the airway. They also have profound effects on airway structural cells to reverse the effects of disease on their function. Glucorticosteroids act via specific receptors-the glucocorticosteroid receptor (GR)-which are a member of the nuclear receptor family. As such, many of the important actions of GCs are to modulate gene transcription through a number of distinct and complementary mechanisms. Targets genes include most inflammatory mediators such as chemokines, cytokines, growth factors and their receptors. GCs delivered by the inhaled route are very effective for most patients and have few systemic side effects. However, in some patients, even high doses of topical or even systemic GCs fail to control their disease. A number of mechanisms relating to inflammation have been reported to be responsible for the failure of these patients to respond correctly to GCs and these provide insight into GC actions within the airways. In these patients, the side-effect profile of GCs prevent continued use of high doses and new drugs are needed for these patients. Targeting the defective pathways associated with GC function in these patients may also reactivate GC responsiveness.

Abstract
Comorbidities are common in elderly individuals with chronic respiratory diseases. They can affect disease manifestations and severity and can even impact management. Comorbidities can affect the treatment of the lung disease, particularly because of the interaction with the respiratory drugs. Thus, a multidimensional approach with multidisciplinary intervention is suggested for elderly respiratory patients, switching from a disease-oriented scheme to a dysfunction-oriented approach. Unfortunately, older individuals are often excluded from clinical trials because of advanced age and comorbidities. This article reviews the role of comorbidities in the management of respiratory diseases in the elderly.

Abstract
BACKGROUND Regular use of inhaled corticosteroids (ICS) in patients with obstructive lung diseases has been associated with a higher risk of pneumonia, particularly in COPD. The risk of pneumonia has not been previously evaluated in relation to ICS particle size and dose used. METHODS Historical cohort, UK database study of 23,013 patients with obstructive lung disease aged 12-80 years prescribed extra-fine or fine-particle ICS. The endpoints assessed during the outcome year were diagnosis of pneumonia, acute exacerbations and acute respiratory events in relation to ICS dose. To determine the association between ICS particle size, dose and risk of pneumonia in unmatched and matched treatment groups, logistic and conditional logistic regression models were used. RESULTS 14788 patients were stepped-up to fine-particle ICS and 8225 to extra-fine ICS. On unmatched analysis, patients stepping-up to extra-fine ICS were significantly less likely to be coded for pneumonia (adjusted odds ratio [aOR] 0.60; 95% CI 0.37, 0.97]); experience acute exacerbations (adjusted risk ratio [aRR] 0.91; 95%CI 0.85, 0.97); and acute respiratory events (aRR 0.90; 95%CI 0.86, 0.94) compared with patients stepping-up to fine-particle ICS. Patients prescribed daily ICS doses in excess of 700 mcg (fluticasone propionate equivalent) had a significantly higher risk of pneumonia (OR [95%CI] 2.38 [1.17, 4.83]) compared with patients prescribed lower doses, irrespective of particle size. CONCLUSIONS These findings suggest that patients with obstructive lung disease on extra-fine particle ICS have a lower risk of pneumonia than those on fine-particle ICS, with those receiving higher ICS doses being at a greater risk.

Abstract
BACKGROUND Worldwide, chronic obstructive pulmonary disease (COPD) is a highly prevalent chronic lung disease with considerable clinical and socioeconomic impact. Pharmacologic maintenance drugs (such as bronchodilators and inhaled corticosteroids) play an important role in the treatment of COPD. The cost effectiveness of these treatments has been frequently assessed, but studies to date have largely neglected the impact of treatment sequence and the exact stage of disease in which the drugs are used in real life. OBJECTIVE We aimed to systematically review recently published articles that reported the cost effectiveness of COPD maintenance treatments, with a focus on key findings, quality and methodological issues. METHODS We performed a systematic literature search in Embase, PubMed, the UK NHS Economic Evaluation Database (NHS-EED) and EURONHEED (European Network of Health Economics Evaluation Databases) and included all relevant articles published between 2011 and 2015 in either Dutch, English or German. Main study characteristics, methods and outcomes were extracted and critically assessed. The Quality of Health Economic Studies (QHES) instrument was used as basis for quality assessment, but additional items were also addressed. RESULTS The search identified 18 recent pharmacoeconomic analyses of COPD maintenance treatments. Papers reported the cost effectiveness of long-acting muscarinic antagonist (LAMA) monotherapy (n = 6), phosphodiesterase (PDE)-4 inhibitors (n = 4), long-acting beta agonist/inhaled corticosteroid (LABA/ICS) combinations (n = 4), LABA monotherapy (n = 2) and LABA/LAMA combinations (n = 2). All but two studies were funded by the manufacturer, and all studies indicated favourable cost effectiveness; however, the number of quality-adjusted life-years (QALYs) gained was small. Less than half of the studies reported a COPD-specific outcome in addition to a generic outcome (mostly QALYs). Exacerbation and mortality rates were found to be the main drivers of cost effectiveness. According to the QHES, the quality of the studies was generally sufficient, but additional assessment revealed that most studies poorly represented the cost effectiveness of real-life medication use. CONCLUSIONS The majority of studies showed that pharmacologic COPD maintenance treatment is cost effective, but most studies poorly reflected real-life drug use. Consistent and COPD-specific methodology is recommended.

CLINICAL RESPIRATORY JOURNAL 2016; 12:659-665.

Abstract
INTRODUCTION Prolonged use of systemic corticosteroids leads to reduced bone mineral density and osteoporosis, in turn increasing the risk of minimal trauma fractures with their associated morbidity and mortality in elderly populations. However, the effect of inhaled corticosteroids on bone mineral density has been debated in the medical literature. OBJECTIVES We aimed to determine the effect of inhaled corticosteroids on bone mineral density measured using calcaneal quantitative ultrasonography in a cohort of older Australians. METHODS Data was collected from the Hunter Community Study, a longitudinal cohort of Australians aged 55-85. Simple and multiple linear regression methods were used to test the cross-sectional association between inhaled corticosteroids and calcaneal bone mineral density measured with quantitative ultrasound at baseline. A causal diagram was used to determine the minimally sufficient number of co-variates necessary to determine the unconfounded effect of inhaled corticosteroids on bone mineral density; these included gender, body mass index, smoking, asthma, alcohol use, age, physical activity, and diet. RESULTS There were 152 (6.8%) patients on inhaled corticosteroids and 2098 (93%) controls. Simple and multiple linear regression methods showed a non-significant effect of inhaled steroids on BMD with slight decrease of BMD -0.010 g/cm2 (95% CI -0.042 to 0.022, P = .55) and -0.013 g/cm2 (95% CI -0.062 to 0.036, P = .61) respectively. Age, gender, body mass index, and smoking were stronger predictors of BMD. CONCLUSIONS No statistically significant relationship was detected between the use of inhaled corticosteroids and reduced bone mineral density in this observational study of a cohort of older Australians.

[PMID: 27808096 PMCID: PMC5093405 DOI: 10.1038/npjpcrm.2016.61] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Accepted: 06/19/2016] [Indexed: 12/11/2022] Open
Abstract
Clinical guidelines recommend long-acting bronchodilators as first maintenance therapy for chronic obstructive pulmonary disease (COPD), with inhaled corticosteroids (ICS) reserved for patients with more severe disease and exacerbations. The aim of this analysis was to examine real-life prescribing of first maintenance therapy for COPD in the UK. Data were extracted from the UK Optimum Patient Care Research Database for patients with a first prescription for COPD maintenance therapy between 2009 and 2012 and a diagnosis of COPD at or before the date of the first prescription for COPD maintenance therapy. Routine clinical data including demographics, disease history and symptoms, comorbidities, therapy, hospitalisation rate and exacerbation rate were collected and used to characterise patients stratified by disease severity and Global Initiative for Chronic Obstructive Lung Disease (GOLD) group (A–D). The analysis population included 2,217 individuals (55.4% male, 45.2% smokers). Long-acting muscarinic antagonists (LAMA) as monotherapy were prescribed as first maintenance therapy for 40.2% of patients. ICS were prescribed as ICS/long-acting beta-agonists combination for 29.1% of patients or as monotherapy for 15.5%. ICS (alone or in combination) were prescribed to >40% of patients in each GOLD group. ICS-containing regimens were prescribed to patients with a history of pneumonia and comorbid conditions for whom the risks of ICS therapy may outweigh the benefits. The clinical reality of prescribing indicates that ICS are often prescribed outside current guideline recommendations for many patients newly diagnosed with COPD in the UK. Encouragingly, LAMAs are increasingly being prescribed as first maintenance therapy for these patients.

Abstract
Background Management guidelines for chronic obstructive pulmonary disease (COPD) recommend that inhaled corticosteroids (ICS) are prescribed to patients with the most severe symptoms. However, these guidelines have not been widely implemented by physicians, leading to widespread use of ICS in patients with mild-to-moderate COPD. Of particular concern is the potential risk of worsening diabetic control associated with ICS use. Here we investigate whether ICS therapy in patients with COPD and comorbid type 2 diabetes mellitus (T2DM) has a negative impact on diabetic control, and whether these negative effects are dose-dependent. Methods and Findings This was a historical matched cohort study utilising primary care medical record data from two large UK databases. We selected patients aged ≥40 years with COPD and T2DM, prescribed ICS (n = 1360) or non-ICS therapy (n = 2642) between 2008 and 2012. The primary endpoint was change in HbA1c between the baseline and outcome periods. After 1:1 matching, each cohort consisted of 682 patients. Over the 12–18-month outcome period, patients prescribed ICS had significantly greater increases in HbA1c values compared with those prescribed non-ICS therapies; adjusted difference 0.16% (95% confidence interval [CI]: 0.05–0.27%) in all COPD patients, and 0.25% (95% CI: 0.10–0.40%) in mild-to-moderate COPD patients. Patients in the ICS cohort also had significantly more diabetes-related general practice visits per year and received more frequent glucose strip prescriptions, compared with those prescribed non-ICS therapies. Patients prescribed higher cumulative doses of ICS (>250 mg) had greater odds of increased HbA1c and/or receiving additional antidiabetic medication, and increased odds of being above the Quality and Outcomes Framework (QOF) target for HbA1c levels, compared with those prescribed lower cumulative doses (≤125 mg). Conclusion For patients with COPD and comorbid T2DM, ICS therapy may have a negative impact on diabetes control. Patients prescribed higher cumulative doses of ICS may be at greater risk of diabetes progression. Trial Registration ENCePP ENCEPP/SDPP/6804

Pheretima aspergillum decoction suppresses inflammation and relieves asthma in a mouse model of bronchial asthma by NF-κB inhibition. JOURNAL OF ETHNOPHARMACOLOGY 2016; 189:22-30. [PMID: 27184188 DOI: 10.1016/j.jep.2016.05.028] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/07/2015] [Revised: 02/19/2016] [Accepted: 05/11/2016] [Indexed: 06/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE AND AIM OF THE STUDY Guang-Pheretima, the live form of the earthworm Pheretima aspergillum, is a traditional Chinese medicine commonly used for the treatment of asthma, cough, stroke, epilepsy and other diseases due to its anti-inflammatory, anti-asthmatic, anti-seizure, thrombolytic and diuretic properties. Although Guang-Pheretima is effective in the relief of asthma, its pharmacological activity and the underlying molecular mechanisms are not fully understood. Hence, we investigated the effects of a Pheretima aspergillum decoction (PAD) against inflammation in a model of ovalbumin (OVA)-induced asthma in BALB/c mice, as well as the nuclear factor-κB (NF-κB) pathway involved in this process. MATERIALS AND METHODS OVA was used to sensitize and challenge the airway of the mice, and PAD was administrated by gavage. We measured airway hyperresponsiveness (AHR) in the mice 24h following a final methacholine challenge with whole-body plethysmography. The bronchoalveolar lavage fluid (BALF), serum and pulmonary tissues were collected 48h after the last challenge. The levels of inflammatory factors and the related mRNAs were determined by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (RT-PCR), respectively. The number of differential inflammatory cells in the BALF was counted. Serum total and OVA-specific IgE levels were measured with ELISA. The activation of NF-κB signaling in the lung was detected by western blotting. In addition, the lung tissues were stained with hematoxylin and eosin or periodic acid Schiff stain for histopathological examination. RESULTS PAD treatment significantly alleviated AHR in the asthmatic mice, decreased the mRNA and protein levels of IL-4, IL-5 and IL-13 and downregulated IgE. In addition, PAD treatment attenuated mucus secretion and infiltration of inflammatory cells in the lung while inhibiting the activation of NF-κB signaling. CONCLUSIONS PAD effectively inhibited the activation of NF-κB signaling in the lungs of mice with OVA-induced asthma, and mitigated AHR and Th2 type inflammatory reactions. Therefore, PAD may serve as a drug candidate for asthma treatment.

Abstract
The skeletal effects of inhaled glucocorticoids are poorly understood. Children with asthma treated with inhaled glucocorticoids have lower growth velocity, bone density, and adult height. Studies of adults with asthma have reported variable effects on BMD, although prospective studies have demonstrated bone loss after initiation of inhaled glucocorticoids in premenopausal women. There is a dose-response relationship between inhaled glucocorticoids and fracture risk in asthmatics; the risk of vertebral and non-vertebral fractures is greater in subjects treated with the highest doses in the majority of studies. Patients with COPD have lower BMD and higher fracture rates compared to controls, however, the majority of studies have not found an additional detrimental effect of inhaled glucocorticoids on bone. While the evidence is not conclusive, it supports using the lowest possible dose of inhaled glucocorticoids to treat patients with asthma and COPD and highlights the need for further research on this topic.

Abstract
Asthma is a heterogeneous disease with many phenotypes, and age at disease onset is an important factor in separating the phenotypes. Most studies with asthma have been performed in patients being otherwise healthy. However, in real life, comorbid diseases are very common in adult patients. We review here the emerging comorbid conditions to asthma such as obesity, metabolic syndrome, diabetes mellitus type 2 (DM2), and cardiac and psychiatric diseases. Their role as risk factors for incident asthma and whether they affect clinical asthma are evaluated. Obesity, independently or as a part of metabolic syndrome, DM2, and depression are risk factors for incident asthma. In contrast, the effects of comorbidities on clinical asthma are less well-known and mostly studies are lacking. Cross-sectional studies in obese asthmatics suggest that they may have less well controlled asthma and worse lung function. However, no long-term clinical follow-up studies with these comorbidities and asthma were identified. These emerging comorbidities often occur in the same multimorbid adult patient and may have in common metabolic pathways and inflammatory or other alterations such as early life exposures, systemic inflammation, inflammasome, adipokines, hyperglycemia, hyperinsulinemia, lung mechanics, mitochondrial dysfunction, disturbed nitric oxide metabolism, and leukotrienes.

Abstract
Bronchiectasis and asthma are common respiratory diseases worldwide. However, the influence of asthma on bronchiectasis remains unclear. The objective of this study is to analyse the effects of asthma on bronchiectasis exacerbation.Data from inpatients diagnosed with bronchiectasis with or without asthma at Shanghai Pulmonary Hospital (Shanghai, China) between January 2013 and December 2014 were retrospectively collected and analysed. 249 patients with only bronchiectasis and 214 patients with both bronchiectasis and asthma were included in the study. Follow-up records were used to evaluate the effect of asthma on bronchiectasis exacerbation.The variables found to be independently associated with bronchiectasis exacerbations were age (OR 1.07, 95% CI 1.03-1.11; p<0.001), duration of symptoms (OR 1.06, 95% CI 1.03-1.09; p<0.001), the presence of asthma (OR 2.6, 95% CI 1.15-5.88; p=0.021), forced expiratory volume in 1 s <50% predicted (OR 4.03, 95% CI 1.75-9.26; p=0.001), isolation of Pseudomonas aeruginosa in sputum (OR 2.41, 95% CI 1.00-5.79; p=0.05) and lung lesion extension to more than two lobes (OR 2.73, 95% CI 1.16-6.45; p=0.022).The existence of asthma was associated with an independent increase in risk of bronchiectasis exacerbation.

Abstract
Inhaled corticosteroids (ICSs) are widely used in the treatment of patients with chronic obstructive pulmonary diseases. However, high-dose regimens and long-term use of ICSs have the potential to cause a variety of local and systemic side effects such as candidiasis, cataracts, glaucoma, and osteoporosis. The use of ICSs can also be associated with the risk of bone fractures, diabetes mellitus and pneumonia. These ICS-related side effects are of particular importance in elderly patients due to the presence of comorbidities and age-related behavioral, cognitive, and psychological problems, which can all interact with inhaled treatment. We reviewed the available literature on the clinically relevant side effects of ICSs in the elderly to provide practical measures to properly monitor and manage the risk of ICSs in the geriatric population. Inspection of the mouth, monitoring of ocular pressure, and use of bone-protective drugs may be necessary in patients on prolonged ICS therapy. Above all, the use of the lowest possible ICS dose and a careful re-assessment of the inhalation procedure should be recommended. Taken together, these observations suggest that physicians should use ICSs appropriately for those patients in whom the benefit will outweigh the risk, especially chronic obstructive pulmonary disease (COPD) patients with previous frequent exacerbations. Given the paucity of information on the topic and the need to extrapolate the results from studies with broader age ranges, we strongly encourage the design of specifically tailored clinical studies in the elderly.

Abstract
Background Low health literacy is a common problem among older adults. It is often suggested to be associated with poor adherence. This suggested association implies a need for effective adherence interventions in low health literate people. However, previous reviews show mixed results on the association between low health literacy and poor adherence. A systematic meta-review of systematic reviews was conducted to study the association between health literacy and adherence in adults above the age of 50. Evidence for the effectiveness of adherence interventions among adults in this age group with low health literacy was also explored. Methods Eight electronic databases (MEDLINE, ERIC, EMBASE, PsycINFO, CINAHL, DARE, the Cochrane Library, and Web of Knowledge) were searched using a variety of keywords regarding health literacy and adherence. Additionally, references of identified articles were checked. Systematic reviews were included if they assessed the association between health literacy and adherence or evaluated the effectiveness of interventions to improve adherence in older adults with low health literacy. The AMSTAR tool was used to assess the quality of the included reviews. The selection procedure, data-extraction, and quality assessment were performed by two independent reviewers. Seventeen reviews were selected for inclusion. Results Reviews varied widely in quality. Both reviews of high and low quality found only weak or mixed associations between health literacy and adherence among older adults. Reviews report on seven studies that assess the effectiveness of adherence interventions among low health literate older adults. The results suggest that some adherence interventions are effective for this group. The interventions described in the reviews focused mainly on education and on lowering the health literacy demands of adherence instructions. No conclusions could be drawn about which type of intervention could be most beneficial for this population. Conclusions Evidence on the association between health literacy and adherence in older adults is relatively weak. Adherence interventions are potentially effective for the vulnerable population of older adults with low levels of health literacy, but the evidence on this topic is limited. Further research is needed on the association between health literacy and general health behavior, and on the effectiveness of interventions.

Abstract
Asthma affects older adults to the same extent as children and adolescents. However, one is led to imagine that asthma prevalence decreases with aging and becomes a rare entity in the elderly. From a clinical perspective, this misconception has nontrivial consequences in that the recognition of the disease is delayed and the treatment postponed. The overall management of asthma in the elderly population is also complicated by specific features that the disease develops in the most advanced ages, and by the difficulties that the physician encounters when approaching the older asthmatic subjects. The current review article aims at describing the specific clinical presentations of asthma in the elderly and highlights the gaps and pitfalls in the diagnostic and therapeutic approaches. Relevant issues with regard to the clinical management of asthma in the elderly are also discussed.

Abstract
OBJECTIVES Fluticasone furoate (FF; inhaled corticosteroid) combined with vilanterol (VI; long-acting beta(2) agonist) is a once-daily therapy for asthma and chronic obstructive pulmonary disease. This 12-week phase III study compared the efficacy and safety of once-daily (evening dosing) FF/VI 100/25 mcg versus FF 100 mcg (primary objective) and FF/VI 100/25 mcg versus FF/VI 200/25 mcg (descriptive comparison only) in patients (n = 1039) ≥12 years with moderate-to-severe persistent asthma. METHODS The primary end point was weighted mean (wm) 0-24-h serial forced expiratory volume in 1 s (FEV(1)) at week 12. Secondary end points (change from baseline) were trough FEV(1) and the proportion (%) of rescue-free 24-h periods (both powered), the proportion (%) of symptom-free 24-h periods, and morning and evening peak expiratory flow (PEF). Safety data (adverse events, AEs) were collected throughout. RESULTS Compared with FF 100 mcg, FF/VI 100/25 mcg significantly improved wmFEV(1) (p < 0.001), trough FEV(1) (p = 0.014), % rescue-free (p < 0.001), % symptom-free (p = 0.002) 24-h periods, and morning and evening PEF (p < 0.001). FF/VI 200/25 mcg produced small numerical improvements versus FF/VI 100/25 mcg for all end points. Incidence of AEs was similar across groups. CONCLUSIONS FF/VI 100/25 mcg resulted in significant improvements in all primary and secondary end points versus FF 100 mcg. Numerical improvements occurred with FF/VI 200/25 mcg versus FF/VI 100/25 mcg. All treatments were well tolerated.

Abstract
Inhaled corticosteroids (ICSs) are widely used in the treatment of patients with chronic obstructive pulmonary diseases. However, high-dose regimens and long-term use of ICSs have the potential to cause a variety of local and systemic side effects such as candidiasis, cataracts, glaucoma, and osteoporosis. The use of ICSs can also be associated with the risk of bone fractures, diabetes mellitus and pneumonia. These ICS-related side effects are of particular importance in elderly patients due to the presence of comorbidities and age-related behavioral, cognitive, and psychological problems, which can all interact with inhaled treatment. We reviewed the available literature on the clinically relevant side effects of ICSs in the elderly to provide practical measures to properly monitor and manage the risk of ICSs in the geriatric population. Inspection of the mouth, monitoring of ocular pressure, and use of bone-protective drugs may be necessary in patients on prolonged ICS therapy. Above all, the use of the lowest possible ICS dose and a careful re-assessment of the inhalation procedure should be recommended. Taken together, these observations suggest that physicians should use ICSs appropriately for those patients in whom the benefit will outweigh the risk, especially chronic obstructive pulmonary disease (COPD) patients with previous frequent exacerbations. Given the paucity of information on the topic and the need to extrapolate the results from studies with broader age ranges, we strongly encourage the design of specifically tailored clinical studies in the elderly.

Abstract
Despite the 2007 National Asthma Education and Prevention Program Expert Panel 3 guidelines for the treatment of uncontrolled asthma, many patients with poorly controlled asthma still continue to tax the health care system. Controlling asthma symptoms and preventing acute exacerbations have been the foundation of care. Using long-term controller treatments such as inhaled corticosteroids (ICS) and inhaled long-acting beta2-agonists (LABAs) is a common approach. While patient responses to recommended pharmacotherapy may vary, poor adherence to therapy also contributes to poor asthma control. A once-daily combination inhaler, such as fluticasone furoate, an ICS, in combination with vilanterol, a LABA, offers increased convenience and potential improved adherence, which should result in enhanced clinical outcomes and reduced exacerbations. The ICS/LABA combination inhaler of fluticasone furoate and vilanterol is currently approved in the United States for use in the maintenance of chronic obstructive pulmonary disease and to reduce exacerbations. This paper reviews the expanding literature on the efficacy of fluticasone furoate and vilanterol in treating asthma.
