Association between bronchiectasis exacerbations and longitudinal changes in FEV 1 in patients from the US bronchiectasis and NTM research registry. Respir Med 2024; 228:107660. [PMID: 38734153 DOI: 10.1016/j.rmed.2024.107660] [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: 12/10/2023] [Revised: 04/30/2024] [Accepted: 05/06/2024] [Indexed: 05/13/2024]
Abstract
BACKGROUND This study aimed to evaluate the association between the number of non-cystic fibrosis bronchiectasis (bronchiectasis) exacerbations during baseline and follow-up (objective 1) and to identify longitudinal changes in FEV1 associated with exacerbation frequency (objective 2). METHODS This was a retrospective cohort study of adult patients enrolled in the US Bronchiectasis and Nontuberculous Mycobacteria Research Registry September 2008 to March 2020. Objective 1 outcome was association between exacerbations during baseline (24 months) and 0-to-24 month and 24-to-48 month follow-up windows. Objective 2 outcomes were change in FEV1 and FEV1 % predicted over 24 months stratified by baseline exacerbation frequency. RESULTS Objective 1 cohort (N = 520) baseline frequency of any exacerbations was 59.2%. Overall, 71.4% and 75.0% of patients with ≥1 baseline exacerbations had ≥1 exacerbations during the 0-to-24 and 24-to-48 month follow-ups. Having ≥1 exacerbation during baseline was significantly associated with ≥1 exacerbation during the 0-to-24 month (P = 0.0085) and 24-to-48 month follow-ups (P=<0.0001). Objective 2 cohort (N = 431) baseline FEV1 was significantly lower in patients who had more exacerbations; however, decline in FEV1 from baseline was not significantly different between patients with 0, 1, and ≥2 exacerbations. In patients with more baseline exacerbations, FEV1 % predicted was significantly lower at baseline (P < 0.0001) and at 12 (P = 0.0002) and 24 month follow-ups (P < 0.0001). CONCLUSIONS Patients with frequent bronchiectasis exacerbations may be more likely than those with less frequent exacerbations to experience disease progression based on future exacerbation frequency and lower FEV1 at baseline, although FEV1 decline may not differ by baseline exacerbation frequency.

Lei C, Zeng Z, Chen F, Guo Y, Liu Y. Eosinophilic bronchiectasis increases length and cost of hospitalization: a retrospective analysis in a hospital of southern China from 2012 to 2020. BMC Pulm Med 2024; 24:98. [PMID: 38408986 PMCID: PMC10895853 DOI: 10.1186/s12890-024-02912-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Accepted: 02/16/2024] [Indexed: 02/28/2024] Open
Abstract
BACKGROUND The concept of eosinophilic bronchiectasis has received clinical attention recently, but the association between blood eosinophil count (BEC) and hospital characteristics has rarely been reported yet. We aim to investigate the clinical impact of BEC on patients with acute bronchiectasis exacerbation. METHODS A total of 1332 adult patients diagnosed with acute exacerbation of bronchiectasis from January 2012 to December 2020 were included in this retrospective study. A propensity-matched analysis was performed by matching age, sex and comorbidities in patients with high eosinophil count (≥ 300 cell/µL) and low eosinophil count (< 300 cell/µL). Clinical characteristics, length of hospital stay (LOS), hospitalization cost and inflammatory markers were compared between the two groups. RESULTS Eosinophilic bronchiectasis occurred in approximately 11.7% of all patients. 156 propensity score-matched pairs were identified with and without high eosinophil count. Eosinophilic bronchiectasis presented with a longer LOS [9.0 (6.0-12.5) vs. 5.0 (4.0-6.0) days, p < 0.0001] and more hospitalization cost [15,011(9,753-27,404) vs. 9,109(6,402-12,287) RMB, p < 0.0001] compared to those in non-eosinophilic bronchiectasis. The median white blood cell (WBC), lymphocyte, platelet (PLT) and C-reactive protein (CRP) levels in eosinophilic bronchiectasis were significantly increased. Multivariate logistic regression analysis confirmed that the high levels of eosinophil count (OR = 13.95, p < 0.0001), worse FEV1% predicted (OR = 7.80, p = 0.0003) and PLT (OR = 1.01, p = 0.035) were independent prognostic factors for length of hospital (LOS) greater than 7 days. CONCLUSION Eosinophilic bronchiectasis patients had longer length of hospital stay and more hospitalization cost compared to those in non-eosinophilic bronchiectasis group, which might be associated with the stronger inflammatory reaction.

Chest 2023; 164:1396-1421. [PMID: 37423293 DOI: 10.1016/j.chest.2023.06.040] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 04/20/2023] [Accepted: 06/19/2023] [Indexed: 07/11/2023] Open
Abstract
BACKGROUND Bronchiectasis, a previously neglected condition, now has renewed research interest. There are a few systematic reviews that have reported on the economic and societal burden of bronchiectasis in adults, but none have reported on children. We undertook this systematic review to estimate the economic burden of bronchiectasis in children and adults. RESEARCH QUESTION What is the health care resource utilization and economic burden of bronchiectasis in adults and children? STUDY DESIGN AND METHODS We performed a systematic review identifying publications from Embase, PubMed, Web of Science, Cochrane (trials, reviews, and editorials), and EconLit about the economic burden and health care utilization in adults and children with bronchiectasis between January 1, 2001, and October 10, 2022. We used a narrative synthesis approach and estimated aggregate costs for several countries. RESULTS We identified 53 publications reporting on the economic burden and/or health care utilization of people with bronchiectasis. Total annual health care costs per adult patient ranged from 2021 $3,579 to $82,545 USD and were predominantly driven by hospitalization costs. Annual indirect costs including lost income because of illness (reported in only five studies) ranged from $1,311 to $2,898 USD. Total health care costs in children with bronchiectasis were $23,687 USD annually in the one study that estimated them. Additionally, one publication found that children with bronchiectasis missed 12 school days per year. We estimated aggregate annual health care costs for nine countries, ranging from $101.6 million per year in Singapore to $14.68 billion per year in the United States. We also estimated the aggregate cost of bronchiectasis in Australian children to be $17.77 million per year. INTERPRETATION This review highlights the substantial economic burden of bronchiectasis for patients and health systems. To our knowledge, it is the first systematic review to include the costs for children with bronchiectasis and their families. Future research to examine the economic impact of bronchiectasis in children and economically disadvantaged communities, and to further understand the indirect burden of bronchiectasis on individuals and the community, is needed.

Abstract
Background Patients with bronchiectasis experience persistent symptoms and frequent pulmonary exacerbations; this study investigated the frequency of exacerbations and all-cause hospitalisation. Methods This longitudinal, retrospective, claims database study (IBM® MarketScan®) identified patients aged ≥18 years from 1 July 2015 through 30 September 2018. Exacerbations were identified by bronchiectasis inpatient claim or a healthcare interaction, followed by antibiotic prescription within 7 days. Patients with ≥36 months of continuous health plan enrolment (12 months preceding the first bronchiectasis claim, i.e., baseline period and ≥24 months of follow-up) were included. Patients with cystic fibrosis at baseline were excluded. A multivariable logistic regression model identified baseline factors associated with having ≥2 exacerbations over the 2-year follow-up period. Results In total, 14 798 patients with bronchiectasis were identified; 64.5% were female, 82.7% were aged ≥55 years and 42.7% had ≥2 exacerbations at baseline. Having ≥2 exacerbations after 2 years was positively associated with chronic macrolide use, long-acting β2 agonist use, gastro-oesophageal reflux disease, heart failure and Pseudomonas aeruginosa. Frequent exacerbations (≥2) at baseline were significantly associated with greater likelihood of experiencing ≥2 exacerbations during the first and second year's follow-up (unadjusted odds ratios 3.35 (95% CI 3.1-3.6) and 2.96 (95% CI 2.8-3.2), respectively). The proportion of patients experiencing ≥1 all-cause hospitalisation cumulatively increased from 41.0% in the first year of follow-up to 51.1% over 2 years' follow-up. Conclusion Frequent exacerbations in patients with bronchiectasis may increase the likelihood of future exacerbations over 2 years of follow-up, with increased hospitalisation rates over time.

Abstract
BACKGROUND People with cystic fibrosis (CF) routinely suffer from recurrent sinopulmonary infections. Such infections require frequent courses of antimicrobials and often involve multidrug-resistant organisms. The goal of this study was to identify real-world evidence for the effectiveness of elexacaftor-tezacaftor-ivacaftor (ELX/TEZ/IVA) in decreasing infection-related visits and antimicrobial use in people with CF. METHODS Using IBM MarketScan data, we identified 389 enrollees with CF who began taking ELX/TEZ/IVA before 1 December 2019 and were enrolled from 1 July 2019 to 14 March 2020. We also identified a comparison population who did not begin ELX/TEZ/IVA during the study period. We compared the following outcomes in the 15 weeks before and after medication initiation: total healthcare visits, inpatient visits, infection-related visits, and antimicrobial prescriptions. We analyzed outcomes using both a case-crossover analysis and a difference-in-differences analysis, to control for underlying trends. RESULTS For the case-crossover analysis, ELX/TEZ/IVA initiation was associated with the following changes over a 15-week period: change in overall healthcare visit dates, -2.5 (95% confidence interval, -3.31 to -1.7); change in inpatient admissions, -0.16 (-.22 to -.10); change in infection-related visit dates, -0.62 (-.93 to -.31); and change in antibiotic prescriptions, -0.78 (-1.03 to -.54). Results from the difference-in-differences approach were similar. CONCLUSIONS We show a rapid reduction in infection-related visits and antimicrobial use among people with CF after starting a therapy that was not explicitly designed to treat infections. Currently, there are >30 000 people living with CF in the United States alone. Given that this therapy is effective for approximately 90% of people with CF, the impact on respiratory infections and antimicrobial use may be substantial.

Abstract
BACKGROUND Patients with non-cystic fibrosis bronchiectasis have an increased risk of lung cancer, followed by higher mortality in this population. Because the risk factors of lung cancer have not been well identified, this study aimed to investigate the risk factors of lung cancer in individuals with newly diagnosed bronchiectasis. METHODS This cohort study using the Korean National Health Insurance Service database identified 7425 individuals with incident bronchiectasis among those who participated in the health screening exam in 2009. The cohort was followed from baseline to the date of incident: lung cancer, death, or until the end of the study period. We investigated the risk factors of lung cancer in participants with bronchiectasis using the Cox-proportional hazard models. RESULTS During median 8.3 years of follow-up duration, 1.9% (138/7425) developed lung cancer. In multivariable analyses, significant factors associated with increased risk of incident lung cancer included: males (adjusted hazard ratio [HR] = 3.54, 95% confidence interval [CI] = 2.17-5.79) than females, the overweight (adjusted HR = 1.55, 95% CI = 1.03-2.35) than the normal weight, current smokers (adjusted HR = 3.10, 95% CI = 2.00-4.79) than never smokers, participants living in the rural area (adjusted HR = 2.54, 95% CI = 1.68-3.85) than those living in the metropolitan area. Among comorbidities, chronic obstructive pulmonary disease was associated with an increased risk of lung cancer (adjusted HR = 1.46, 95% CI = 1.01-2.13) in participants with bronchiectasis. In contrast, mild alcohol consumption was associated with reduced risk of lung cancer (adjusted HR = 0.47, 95% CI = 0.29-0.74) in those with bronchiectasis. CONCLUSION This Korean population-based study showed that males, current smoking, overweight, living in rural areas, and comorbid chronic obstructive pulmonary disease are associated with increased risk of lung cancer in individuals with bronchiectasis.

Abstract
INTRODUCTION Bronchiectasis is a chronic condition that is becoming a global health concern. OBJECTIVE To examine the effects of pulmonary rehabilitation (PR) on systemic inflammation, exercise capacity, and quality of life in participants with bronchiectasis. METHODS Participants were randomized to receive PR (outpatient, three weekly sessions for 3 months) or control intervention (usual care + airway clearance therapy + breathing exercises). Data on laboratory (fibrinogen level) and patient-centered outcomes such as physical fitness [6-min walk test (6MWT)] and quality of life were collected. RESULTS A total of 41 participants were evaluated (20 in the intervention group and 21 in the control group). The magnitude of change between baseline and the end of study was greater in the PR group than in the control group-the 6MWT distance increased by a mean of 54 m (54 vs 12 m; p < 0.01), fibrinogen showed a significant reduction (fibrinogen - 92.8 versus - 47.1 mg/dl; p < 0.01), and quality of life improved according to Saint George's Respiratory Questionnaire (SGRQ) (- 7.5 vs 3.2; p < 0.01), which exceeded the minimal clinically important difference of 4 points. CONCLUSION PR effectively improved physical fitness, quality of life, and the degree of systemic inflammation, as reflected by changes in 6 MWT, fibrinogen levels and SGRQ scores. This study supports the inclusion of people with bronchiectasis in supervised PR programs.

Abstract
Rationale It remains unclear whether non-cystic fibrosis bronchiectasis increases the risk of lung cancer, because smoking history was not considered in previous studies. Objectives To evaluate whether participants with bronchiectasis have a higher risk of incident lung cancer than those without bronchiectasis with information on smoking status. Methods This was a population-based cohort study of 3,858,422 individuals who participated in the 2009 National Health Screening Program. We evaluated the incidence of lung cancer in participants with bronchiectasis (n = 65,305) and those without bronchiectasis (n = 3,793,117). We followed the cohort up until the date of lung cancer diagnosis, date of death, or December 2018. Cox proportional hazard regression models were used to evaluate the relative risk of lung cancer between participants with bronchiectasis and those without bronchiectasis. Results The incidence of lung cancer in participants with bronchiectasis was significantly higher than in those without bronchiectasis (2.1 vs. 0.7 per 1,000 person-years; P < 0.001), with an adjusted hazard ratio (aHR) of 1.22 (95% confidence interval [CI], 1.14–1.30) in the model adjusting for potential confounders and accounting for the competing risk of mortality. Regardless of smoking status, the risk of lung cancer was significantly higher in participants with bronchiectasis than in those without bronchiectasis (aHR, 1.28 [95% CI, 1.17–1.41] for never-smokers; aHR, 1.26 [95% CI, 1.10–1.44] for ever-smokers). Although bronchiectasis did not increase the risk of lung cancer among participants with chronic obstructive pulmonary disease (COPD), it significantly increased the risk of lung cancer in participants without COPD (aHR, 1.19 [95% CI, 1.09–1.31]). Conclusions The presence of bronchiectasis was associated with a higher risk of lung cancer after considering the smoking status.

Abstract
BACKGROUND Bronchiectasis is a common but under-diagnosed chronic disorder characterised by permanent dilation of the airways arising from a cycle of recurrent infection and inflammation. Symptoms including chronic, persistent cough and productive phlegm are a significant burden for people with bronchiectasis, and the main aim of treatment is to reduce exacerbation frequency and improve quality of life. Prophylactic antibiotic therapy aims to break this infection cycle and is recommended by clinical guidelines for adults with three or more exacerbations a year, based on limited evidence. It is important to weigh the evidence for bacterial suppression against the prevention of antibiotic resistance and further evidence is required on the safety and efficacy of different regimens of intermittently administered antibiotic treatments for people with bronchiectasis. OBJECTIVES To evaluate the safety and efficacy of intermittent prophylactic antibiotics in the treatment of adults and children with bronchiectasis. SEARCH METHODS We identified trials from the Cochrane Airways Trials Register, which contains studies identified through multiple electronic searches and handsearches of other sources. We also searched trial registries and reference lists of primary studies. We conducted searches on 6 September 2021, with no restriction on language of publication. SELECTION CRITERIA We included randomised controlled trials (RCTs) of at least three months' duration comparing an intermittent regime of prophylactic antibiotics with placebo, usual care or an alternate intermittent regimen. Intermittent prophylactic administration was defined as repeated courses of antibiotics with on-treatment and off-treatment intervals of at least 14 days' duration. We included adults and children with a clinical diagnosis of bronchiectasis confirmed by high resolution computed tomography (HRCT), plain film chest radiograph, or bronchography and a documented history of recurrent chest infections. We excluded studies where participants received high dose antibiotics immediately prior to enrolment or those with a diagnosis of cystic fibrosis, allergic bronchopulmonary aspergillosis (ABPA), primary ciliary dyskinesia, hypogammaglobulinaemia, sarcoidosis, or a primary diagnosis of COPD. Our primary outcomes were exacerbation frequency and serious adverse events. We did not exclude studies on the basis of review outcomes. DATA COLLECTION AND ANALYSIS We analysed dichotomous data as odds ratios (ORs) or relative risk (RRs) and continuous data as mean differences (MDs) or standardised mean differences (SMDs). We used standard methodological procedures expected by Cochrane. We conducted GRADE assessments for the following primary outcomes: exacerbation frequency; serious adverse events and secondary outcomes: antibiotic resistance; hospital admissions; health-related quality of life. MAIN RESULTS We included eight RCTs, with interventions ranging from 16 to 48 weeks, involving 2180 adults. All evaluated one of three types of antibiotics over two to six cycles of 28 days on/off treatment: aminoglycosides, ß-lactams or fluoroquinolones. Two studies also included 12 cycles of 14 days on/off treatment with fluoroquinolones. Participants had a mean age of 63.6 years, 65% were women and approximately 85% Caucasian. Baseline FEV1 ranged from 55.5% to 62.6% predicted. None of the studies included children. Generally, there was a low risk of bias in the included studies. Antibiotic versus placebo: cycle of 14 days on/off. Ciprofloxacin reduced the frequency of exacerbations compared to placebo (RR 0.75, 95% CI 0.61 to 0.93; I2 = 65%; 2 studies, 469 participants; moderate-certainty evidence), with eight people (95% CI 6 to 28) needed to treat for an additional beneficial outcome. The intervention increased the risk of antibiotic resistance more than twofold (OR 2.14, 95% CI 1.36 to 3.35; I2 = 0%; 2 studies, 624 participants; high-certainty evidence). Serious adverse events, lung function (FEV1), health-related quality of life, and adverse effects did not differ between groups. Antibiotic versus placebo: cycle of 28 days on/off. Antibiotics did not reduce overall exacerbation frequency (RR 0.92, 95% CI 0.82 to 1.02; I2 = 0%; 8 studies, 1695 participants; high-certainty evidence) but there were fewer severe exacerbations (OR 0.59, 95% CI 0.37 to 0.93; I2 = 54%; 3 studies, 624 participants), though this should be interpreted with caution due to low event rates. The risk of antibiotic resistance was more than twofold higher based on a pooled analysis (OR 2.20, 95% CI 1.42 to 3.42; I2 = 0%; 3 studies, 685 participants; high-certainty evidence) and consistent with unpooled data from four further studies. Serious adverse events, time to first exacerbation, duration of exacerbation, respiratory-related hospital admissions, lung function, health-related quality of life and adverse effects did not differ between study groups. Antibiotic versus usual care. We did not find any studies that compared intermittent antibiotic regimens with usual care. Cycle of 14 days on/off versus cycle of 28 days on/off. Exacerbation frequency did not differ between the two treatment regimens (RR 1.02, 95% CI 0.84 to 1.24; I2 = 71%; 2 studies, 625 participants; moderate-certainty evidence) However, inconsistencies in the results from the two trials in this comparison indicate that the apparent aggregated similarities may not be reliable. There was no evidence of a difference in antibiotic resistance between groups (OR 1.00, 95% CI 0.68 to 1.48; I2 = 60%; 2 studies, 624 participants; moderate-certainty evidence). Serious adverse events, adverse effects, lung function and health-related quality of life did not differ between the two antibiotic regimens. AUTHORS' CONCLUSIONS Overall, in adults who have frequent chest infections, long-term antibiotics given at 14-day on/off intervals slightly reduces the frequency of those infections and increases antibiotic resistance. Intermittent antibiotic regimens result in little to no difference in serious adverse events. The impact of intermittent antibiotic therapy on children with bronchiectasis is unknown due to an absence of evidence, and further research is needed to establish the potential risks and benefits.

[PMID: 34708114 PMCID: PMC8542960 DOI: 10.1183/23120541.00334-2021] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Accepted: 07/16/2021] [Indexed: 11/05/2022] Open
Abstract
Background and objective Little is known about the epidemiology and cost of bronchiectasis in Asia. This study describes the disease burden of bronchiectasis in Singapore. Methods A nationwide administrative dataset was used to identify hospitalisations with bronchiectasis as a diagnosis. Population statistics and medical encounter data were used to estimate the incidence, mortality, prevalence and direct medical costs associated with bronchiectasis requiring hospitalisation. Results There were 420 incident hospitalised bronchiectasis patients in 2017, giving an incidence rate of 10.6 per 100 000. Age-standardised incidence declined on average by 2.7% per year between 2007 and 2017. Incidence rates increased strongly with age in both men and women. Tuberculosis was a secondary diagnosis in 37.5% of incident hospitalisations in 2007, but has declined sharply since then. Patient survival was considerably lower in both men (5-year relative survival ratios (RSR) 0.63, 95% CI 0.59–0.66) and women (5-year RSR 0.75, 95% CI 0.72–0.78). The point prevalence of bronchiectasis was 147.1 per 100 000 in 2017, and increased sharply with age, with >1% of people aged ≥75 years having bronchiectasis. Total first-year costs among incident bronchiectasis patients in 2016 varied widely, with a mean±sd USD 7331±8863. Approximately 10% of the patients admitted in 2016 had total first-year costs of more than USD 14 380. Conclusion Bronchiectasis is common and imposes a substantial burden on healthcare costs and survival rates of patients in Singapore. Bronchiectasis is common, with a prevalence >1% in older persons, and imposes a substantial burden on healthcare costs and survival rates of patients living with bronchiectasis in Singaporehttps://bit.ly/3iErV79

Impact of non-cystic fibrosis bronchiectasis on critically ill patients in Korea: a retrospective observational study. Sci Rep 2021; 11:15757. [PMID: 34345008 PMCID: PMC8333349 DOI: 10.1038/s41598-021-95366-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Accepted: 07/26/2021] [Indexed: 11/26/2022] Open
Abstract
This study investigated the impact of bronchiectasis on patients admitted to the intensive care unit (ICU) at a hospital in Korea. Patients with bronchiectasis were diagnosed using results of chest computed tomography performed before ICU admission. The severity of bronchiectasis was based on the number of affected lobes, and patients with ≥ 3 bronchiectatic lobes were classified into the severe bronchiectasis group. Overall, 823 patients were enrolled. The mean age was 66.0 ± 13.9 years, and 63.4% were men. Bronchiectasis and severe bronchiectasis were present in 148 (18.0%) and 108 (13.1%) patients, respectively. The increase in the number of bronchiectatic lobes was related to the rise in ICU mortality (P for trend = 0.012) and in-hospital mortality (P for trend = 0.004). Patients with severe bronchiectasis had higher odds for 28-day mortality [odds ratio (OR) 1.122, 95% confidence interval (CI) 1.024–1.230], ICU mortality (OR 1.119, 95% CI 1.023–1.223), and in-hospital mortality (OR 1.208, 95% CI 1.092–1.337). The severe bronchiectasis group showed lower overall survival (log-rank P < 0.001), and the adjusted hazard ratio was 1.535 (95% CI 1.178–2.001). Severe bronchiectasis had a negative impact on all-cause mortality during ICU and hospital stays, resulting in a lower survival rate.

Increased mortality in patients with non cystic fibrosis bronchiectasis with respiratory comorbidities. Sci Rep 2021; 11:7126. [PMID: 33782457 PMCID: PMC8007811 DOI: 10.1038/s41598-021-86407-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Accepted: 03/15/2021] [Indexed: 11/13/2022] Open
Abstract
There are limited data regarding whether mortality is higher in patients with non cystic fibrosis bronchiectasis (bronchiectasis) than in those without bronchiectasis. Using 2005–2015 data from the Korean National Health Insurance Service, we evaluated hazard ratio (HR) for all-cause mortality in the bronchiectasis cohort relative to the matched cohort. The effect of comorbidities over the study period on the relative mortality was also assessed. All-cause mortality was significantly higher in the bronchiectasis cohort than in the matched cohort (2505/100,000 vs 2142/100,000 person-years, respectively; P < 0.001). Mortality risk was 1.15-fold greater in the bronchiectasis cohort than in the matched cohort (95% confidence interval [CI] 1.09–1.22); mortality was greatest among elderly patients (HR = 1.17, 95% CI 1.10–1.25) and men (HR = 1.19, 95% CI 1.10–1.29). Comorbidities over the study period significantly increased the risk of death in the bronchiectasis cohort relative to the matched cohort: asthma (adjusted HR = 1.20, 95% CI 1.11–1.30), chronic obstructive pulmonary disease (adjusted HR = 1.24, 95% CI 1.15–1.34), pneumonia (adjusted HR = 1.50, 95% CI 1.39–1.63), lung cancer (adjusted HR = 1.85, 95% CI 1.61–2.12), and cardiovascular disease (adjusted HR = 1.34, 95% CI 1.23–1.45). In contrast, there were no significant differences in the risk of death in patients without bronchiectasis-related comorbidities and the matched cohort, except in the case of non-tuberculous mycobacterial infection. In conclusion, all-cause mortality was higher in patients with bronchiectasis cohort than those without bronchiectasis, especially in elderly patients and men. Comorbidities over the study period played a major role in increasing mortality in patients with bronchiectasis relative to those without bronchiectasis.

Abstract
The persistent isolation of Pseudomonas aeruginosa in the airways of non-cystic fibrosis bronchiectasis (NCFB) patients is associated with a worsening of the symptoms, increase of exacerbations, poor quality of life and functional impairment. The objective of this study was the analysis of the eradication rate of P. aeruginosa in the sputum of patients with NCFB treated with inhaled colistin and the effects of the treatment in the exacerbations. This was a prospective, cohort, study of 67 NCFB patients treated with inhaled colistin at the Hospital of A Coruña (Spain). We recorded dyspnoea, exacerbations, lung function and sputum cultures of P. aeruginosa in the patients. The mean age of the patients was 67.25 ± 14.6 years (59.7% male). The percentages of eradication of P. aeruginosa in sputum at 3, 6, 9 and 12 months were 61.2%, 50.7%, 43.3% and 40.3%, respectively. We observed a significant decrease in exacerbations after 1 year of colistin treatment (1.98 ± 3.62) versus the previous year (3.40 ± 4.21, p < 0.001). We conclude that treatment with inhaled colistin in patients with NCFB and P. aeruginosa in sputum can achieve high rates of eradication even in patients with several previous positive cultures, as well as a significant decrease of exacerbations and hospital admissions.

Abstract
INTRODUCTION The prevalence of bronchiectasis in the general population and in individuals undergoing lung cancer screening with low dose computed tomography (LDCT) is unknown. The aim of this study is to estimate the prevalence and impact of bronchiectasis in a screening lung cancer program. METHODS 3028 individuals participating in an international multicenter lung cancer screening consortium (I-ELCAP) were selected from 2000 to 2012. Patients with bronchiectasis on baseline CT were identified and compared to selected controls. Detection of nodules, need for additional studies and incidence of cancer were analyzed over the follow-up period. RESULTS The prevalence of bronchiectasis was 11.6%(354/3028). On the baseline LDCT, the number of subjects with nodules identified was 189(53.4%) in patients with bronchiectasis compared to 63(17.8%) in controls (p<0.001). The occurrence of false positives was higher in subjects with bronchiectasis (26%vs17%;p = 0.003). During follow-up, new nodules were more common among subjects with bronchiectasis (17%vs.12%; p = 0.008). The total number of false positives during follow-up was 29(17.06%) for patients with bronchiectasis vs. 88(12.17%) for controls (p = 0.008).The incidence rate of lung cancer during follow-up was 6.8/1000 and 5.1/1000 person-years for each group respectively (p = 0.62). CONCLUSIONS Bronchiectasis are common among current and former smokers undergoing lung cancer screening with LDCT. The presence of bronchiectasis is associated with greater incidence of new nodules and false positives on baseline and follow-up screening rounds. This leads to an increase need of diagnostic tests, although the lung cancer occurrence is not different.

Abstract
BACKGROUND All-cause mortality risk and causes of death in bronchiectasis patients have not been fully investigated. The aim of this study was to compare the mortality risk and causes of death between individuals with bronchiectasis and those without bronchiectasis. METHODS Patients with or without bronchiectasis determined based on chest computed tomography (CT) at one centre between 2005 and 2016 were enrolled. Among the patients without bronchiectasis, a control group was selected after applying additional exclusion criteria. We compared the mortality risk and causes of death between the bronchiectasis and control groups without lung disease. Subgroup analyses were also performed according to identification of Pseudomonas or non-tuberculous mycobacteria, airflow limitation, and smoking status. RESULTS Of the total 217,702 patients who underwent chest CT, 18,134 bronchiectasis patients and 90,313 non-bronchiectasis patients were included. The all-cause mortality rate in the bronchiectasis group was 1608.8 per 100,000 person-years (95% confidence interval (CI), 1531.5-1690.0), which was higher than that in the control group (133.5 per 100,000 person-years; 95% CI, 124.1-143.8; P < 0.001). The bronchiectasis group had higher all-cause (adjusted hazard ratio (aHR), 1.26; 95% CI, 1.09-1.47), respiratory (aHR, 3.49; 95% CI, 2.21-5.51), and lung cancer-related (aHR, 3.48; 95% CI, 2.33-5.22) mortality risks than the control group. In subgroup analysis, patients with airflow limitation and ever smokers showed higher all-cause mortality risk among bronchiectasis patients. Therefore, we observed significant interrelation between bronchiectasis and smoking, concerning the risks of all-cause mortality (P for multiplicative interaction, 0.030, RERI, 0.432; 95% CI, 0.097-0.769) and lung cancer-related mortality (RERI, 8.68; 95% CI, 1.631-15.736). CONCLUSION Individuals with bronchiectasis had a higher risk of all-cause, respiratory, and lung cancer-related mortality compared to control group. The risk of all-cause mortality was more prominent in those with airflow limitation and in ever smokers.

Abstract
Bronchiectasis is a condition that has been increasingly diagnosed by chest HRCT. In the literature, bronchiectasis is divided into bronchiectasis secondary to cystic fibrosis and bronchiectasis not associated with cystic fibrosis, which is termed non-cystic fibrosis bronchiectasis. Many causes can lead to the development of bronchiectasis, and patients usually have chronic airway symptoms, recurrent infections, and CT abnormalities consistent with the condition. The first international guideline on the diagnosis and treatment of non-cystic fibrosis bronchiectasis was published in 2010. In Brazil, this is the first review document aimed at systematizing the knowledge that has been accumulated on the subject to date. Because there is insufficient evidence on which to base recommendations for various treatment topics, here the decision was made to prepare an expert consensus document. The Brazilian Thoracic Association Committee on Respiratory Infections summoned 10 pulmonologists with expertise in bronchiectasis in Brazil to conduct a critical assessment of the available scientific evidence and international guidelines, as well as to identify aspects that are relevant to the understanding of the heterogeneity of bronchiectasis and to its diagnostic and therapeutic management. Five broad topics were established (pathophysiology, diagnosis, monitoring of stable patients, treatment of stable patients, and management of exacerbations). After this subdivision, the topics were distributed among the authors, who conducted a nonsystematic review of the literature, giving priority to major publications in the specific areas, including original articles, review articles, and systematic reviews. The authors reviewed and commented on all topics, producing a single final document that was approved by consensus.

Abstract
Abstract Non-Cystic Fibrosis Bronchiectasis (NCFB) are characterised by abnormal, permanently damaged and dilated bronchi due to the innapropiate clearence of various microorganisms and recurrent chronic infections.The diagnosis is suggested by the clinical presentation and is confirmed by multiple investigations. There are some comorbidities associated with bronhciectasis, such as chronic obstructive pulmonary disease (COPD), cardiovascular disorders, gastro-esophageal reflux disease (GERD), psychological illnesses, pulmonary hypertension, obstructive apnea syndrome(OSA). The condition has a substantial socioeconomic impact because it requests a multidisciplinary management and periods of exacerbations are common. The aims of the management of bronchiectasis are to reduce symptoms (such as sputum volume and purulence, cough and dyspnea), reduce the frequency and severity of exacerbations, preserve lung function and improve health-related quality of life. The multidisciplinary approach of bronchiectasis patients require along with the medical treatment, a specific plan of nonphamarcological strategies, including balneological intervention. There are a lot of techniques improving the airway clearence, such as: active cycle of breathing techniques (which include breathing control, thoracic expansion exercises, forced expiratory technique), oscilatting possitive expiratory pressure, autogenic drainage, gravity-assisted-positioning, modified postural drainage. Together with specific medication, these techniques can diminuate symptoms and improve the quality of life. Key words: NCFB, airway clearence, physiotherapy,

Abstract
Recent research suggests that bronchiectasis (BE) may be more common than
previously believed and that comorbid chronic obstructive pulmonary disease
(COPD) is widespread in this patient population. Little is known about the
economic burden among patients with BE, and less is known about the burden among
those with comorbid BE + COPD. A retrospective matched-cohort design and data
from a US health-care claims repository were employed. From the source
population comprising adults who had comprehensive medical/drug benefits for ≥1
day in 2013 (i.e. the referent year) and evidence of BE and/or COPD at any time
from 2009 to 2013, patients with BE + COPD were age/sex-matched (1:1:1) to
patients with BE only and patients with COPD only. For each matched subgroup,
annualized levels of respiratory-related and all-cause health-care utilization
and expenditures in 2013 were summarized. Source population included 679,679
patients; among those with BE (n = 31,027), 50% had comorbid
COPD. Mean (95% CI) annual levels of respiratory-related utilization and
expenditures among matched patients with BE + COPD (n = 11,685)
were higher by 2.4–3.5 times versus patients with BE only and 2.0–2.5 times
versus patients with COPD only: hospitalizations, 0.39 (0.37–0.41) versus 0.11
(0.09–0.12) and 0.16 (0.14–0.17); ambulatory encounters, 16.5 (16.1–16.9) versus
6.8 (6.6–7.0) and 8.2 (7.9–8.4); and total expenditures, US$15,685
(14,693–16,678) versus US$5605 (5059–6150) and US$6262 (5655–6868).
Respiratory-related utilization and expenditures are high among patients with BE
or COPD receiving medical care in US clinical practice and are especially high
among those with comorbid BE + COPD receiving medical care, emphasizing the
importance of identifying and treating this unique patient population. Funding
for this research was provided by RespirTech to Policy Analysis Inc. (PAI).

Abstract
Background The increasing prevalence and recognition of bronchiectasis in clinical practice necessitates a better understanding of the economic disease burden to improve the management and achieve better clinical and economic outcomes. This study aimed to assess the economic burden of bronchiectasis based on a review of published literature. Methods A systematic literature review was conducted using MEDLINE, Embase, EconLit and Cochrane databases to identify publications (1 January 2001 to 31 December 2016) on the economic burden of bronchiectasis in adults. Results A total of 26 publications were identified that reported resource use and costs associated with management of bronchiectasis. Two US studies reported annual incremental costs of bronchiectasis versus matched controls of US$5681 and US$2319 per patient. Twenty-four studies reported on hospitalization rates or duration of hospitalization for patients with bronchiectasis. Mean annual hospitalization rates per patient, reported in six studies, ranged from 0.3–1.3, while mean annual age-adjusted hospitalization rates, reported in four studies, ranged from 1.8–25.7 per 100,000 population. The average duration of hospitalization, reported in 12 studies, ranged from 2 to 17 days. Eight publications reported management costs of bronchiectasis. Total annual management costs of €3515 and €4672 per patient were reported in two Spanish studies. Two US studies reported total costs of approximately US$26,000 in patients without exacerbations, increasing to US$36,00–37,000 in patients with exacerbations. Similarly, a Spanish study reported higher total annual costs for patients with > 2 exacerbations per year (€7520) compared with those without exacerbations (€3892). P. aeruginosa infection increased management costs by US$31,551 to US$56,499, as reported in two US studies, with hospitalization being the main cost driver. Conclusions The current literature suggests that the economic burden of bronchiectasis in society is significant. Hospitalization costs are the major driver behind these costs, especially in patients with frequent exacerbations. However, the true economic burden of bronchiectasis is likely to be underestimated because most studies were retrospective, used ICD-9-CM coding to identify patients, and often ignored outpatient burden and cost. We present a conceptual framework to facilitate a more comprehensive assessment of the true burden of bronchiectasis for individuals, healthcare systems and society.

Abstract
BACKGROUND Bronchiectasis is a chronic pulmonary disease characterized by progressive and irreversible bronchial dilatation. The aim of the present study was to investigate the etiologies and clinical features of bronchiectasis in Korean children. METHODS We performed a retrospective review of the medical records for children diagnosed with bronchiectasis between 2000 and 2017 at 28 secondary or tertiary hospitals in South Korea. RESULTS A total of 387 cases were enrolled. The mean age at diagnosis was 9.2 ± 5.1 years and 53.5% of the patients were boys. The most common underlying cause of bronchiectasis was preexisting respiratory infection (55.3%), post-infectious bronchiolitis obliterans (14.3%), pulmonary tuberculosis (12.3%), and heart diseases (5.6%). Common initial presenting symptoms included chronic cough (68.0%), recurrent pneumonia (36.4%), fever (31.1%), and dyspnea (19.7%). The most predominantly involved lesions were left lower lobe (53.9%), right lower lobe (47.1%) and right middle lobe (40.2%). No significant difference was observed in the distribution of these involved lesions by etiology. The forced expiratory volume in 1 s (FEV1) levels were lowest in cases with interstitial lung disease-associated bronchiectasis, followed by those with recurrent aspiration and primary immunodeficiency. CONCLUSIONS Bronchiectasis should be strongly considered in children with chronic cough and recurrent pneumonia. Long-term follow-up studies on pediatric bronchiectasis are needed to further clarify the prognosis and reduce the disease burden in these patients.

Abstract
PURPOSE The objectives of this study were to analyze the characteristics of male and female patients hospitalized with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD) during 2006-2014 according to the presence or absence of bronchiectasis and to study the factors associated with in-hospital mortality (IHM) in patients hospitalized with AE-COPD and concomitant bronchiectasis. METHODS We used the Spanish National Hospital Database to analyze patients admitted with AE-COPD as their primary diagnosis. Patients included in the study were stratified according to the presence or absence of bronchiectasis as their secondary diagnosis. RESULTS We identified 386,646 admissions for AE-COPD, of which 19,679 (5.09%) involved patients with concomitant bronchiectasis. When patients with and without bronchiectasis were compared, we observed that the incidence of infection by Pseudomonas aeruginosa was substantially higher in the former, as were the mean stay, cost, and percentage of readmissions, although IHM and comorbidity were lower. The course of patients with AE-COPD and bronchiectasis was characterized by a gradual increase in prevalence and mean age among men and no differences in prevalence or lower mean age in women. Mortality was 4.24% and 5.02% in patients with and without bronchiectasis, respectively, although significance was lost after a multivariate adjustment (OR 0.94; 95% CI, 0.88-1.01). The factors associated with IHM were older age, higher comorbidity, isolation of P. aeruginosa, mechanical ventilation and readmission. CONCLUSIONS The prevalence of admission with AE-COPD and bronchiectasis increased in men but not in women during the study period. In patients hospitalized with AE-COPD, we did not find differences in mortality when comparing the presence and absence of bronchiectasis. The analysis of temporal trends revealed a significant reduction in mortality from 2006 to 2014 in male patients with COPD and concomitant bronchiectasis, but not among women. It is important to consider the factors associated with IHM such as age, comorbidity, isolation of P. aeruginosa, mechanical ventilation and readmission to better identify those patients who are at greater risk of dying during hospitalization.

Abstract
Estimates of healthcare costs for incident bronchiectasis patients are currently not available for any European country.Out of a sample of 4 859 013 persons covered by German statutory health insurance companies, 231 new bronchiectasis patients were identified in 2012. They were matched with 685 control patients by age, sex and Charlson Comorbidity Index, and followed for 3 years.The total direct expenditure during that period per insured bronchiectasis patient was EUR18 634.57 (95% CI EUR15 891.02–23 871.12), nearly one-third higher (ratio of mean 1.31, 95% CI 1.02–1.68) than for a matched control (p<0.001). Hospitalisation costs contributed to 35% of the total and were >50% higher in the bronchiectasis group (ratio of mean 1.56, 95% CI 1.20–3.01; p<0.001); on average, bronchiectasis patients spent 4.9 (95% CI 2.27–7.43) more days in hospital (p<0.001). Antibiotics expenditures per bronchiectasis outpatient (EUR413.81) were nearly 5 times higher than those for a matched control (ratio of mean 4.85, 95% CI 2.72–8.64). Each bronchiectasis patient had on average 40.5 (95% CI 17.1–43.5) sick-leave days and induced work-loss costs of EUR4230.49 (95% CI EUR2849.58–5611.20). The mortality rate for bronchiectasis and matched non-bronchiectasis patients after 3 years of follow-up was 26.4% and 10.5%, respectively (p<0.001). Mortality in the bronchiectasis group was higher among those who also had chronic obstructive lung disease than in patients with bronchiectasis alone (35.9% and 14.6%, respectively; p<0.001).Although bronchiectasis is considered underdiagnosed, the mortality and associated financial burden in Germany are substantial.

Abstract
Bronchiectasis refers to abnormal dilatation of the bronchi. Airway dilatation can lead to failure of mucus clearance and increased risk of infection. Pathophysiological mechanisms of bronchiectasis include persistent bacterial infections, dysregulated immune responses, impaired mucociliary clearance and airway obstruction. These mechanisms can interact and self-perpetuate, leading over time to impaired lung function. Patients commonly present with productive cough and recurrent chest infections, and the diagnosis of bronchiectasis is based on clinical symptoms and radiological findings. Bronchiectasis can be the result of several different underlying disorders, and identifying the aetiology is crucial to guide management. Treatment is directed at reducing the frequency of exacerbations, improving quality of life and preventing disease progression. Although no therapy is licensed for bronchiectasis by regulatory agencies, evidence supports the effectiveness of airway clearance techniques, antibiotics and mucolytic agents, such as inhaled isotonic or hypertonic saline, in some patients. Bronchiectasis is a disabling disease with an increasing prevalence and can affect individuals of any age. A major challenge is the application of emerging phenotyping and endotyping techniques to identify the patient populations who would most benefit from a specific treatment, with the goal of better targeting existing and emerging treatments and achieving better outcomes.

Abstract
BACKGROUND The diagnosis of bronchiectasis is defined by abnormal dilation of the airways related to a pathological mechanism of progressive airway destruction that is due to a 'vicious cycle' of recurrent bacterial infection, inflammatory mediator release, airway damage, and subsequent further infection. Antibiotics are the main treatment option for reducing bacterial burden in people with exacerbations of bronchiectasis and for longer-term eradication, but their use is tempered against potential adverse effects and concerns regarding antibiotic resistance. The comparative effectiveness, cost-effectiveness, and safety of different antibiotics have been highlighted as important issues, but currently little evidence is available to help resolve uncertainty on these questions. OBJECTIVES To evaluate the comparative effects of different antibiotics in the treatment of adults and children with bronchiectasis. SEARCH METHODS We identified randomised controlled trials (RCTs) through searches of the Cochrane Airways Group Register of trials and online trials registries, run 30 April 2018. We augmented these with searches of the reference lists of published studies. SELECTION CRITERIA We included RCTs reported as full-text articles, those published as abstracts only, and unpublished data. We included adults and children (younger than 18 years) with a diagnosis of bronchiectasis by bronchography or high-resolution computed tomography who reported daily signs and symptoms, such as cough, sputum production, or haemoptysis, and those with recurrent episodes of chest infection; we included studies that compared one antibiotic versus another when they were administered by the same delivery method. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial selection, data extraction, and risk of bias. We assessed overall quality of the evidence using GRADE criteria. We made efforts to collect missing data from trial authors. We have presented results with their 95% confidence intervals (CIs) as mean differences (MDs) or odds ratios (ORs). MAIN RESULTS Four randomised trials were eligible for inclusion in this systematic review - two studies with 83 adults comparing fluoroquinolones with β-lactams and two studies with 55 adults comparing aminoglycosides with polymyxins.None of the included studies reported information on exacerbations - one of our primary outcomes. Included studies reported no serious adverse events - another of our primary outcomes - and no deaths. We graded this evidence as low or very low quality. Included studies did not report quality of life. Comparison between fluoroquinolones and β-lactams (amoxicillin) showed fewer treatment failures in the fluoroquinolone group than in the amoxicillin group (OR 0.07, 95% CI 0.01 to 0.32; low-quality evidence) after 7 to 10 days of therapy. Researchers reported that Pseudomonas aeruginosa infection was eradicated in more participants treated with fluoroquinolones (Peto OR 20.09, 95% CI 2.83 to 142.59; low-quality evidence) but provided no evidence of differences in the numbers of participants showing improvement in sputum purulence (OR 2.35, 95% CI 0.96 to 5.72; very low-quality evidence). Study authors presented no evidence of benefit in relation to forced expiratory volume in one second (FEV₁). The two studies that compared polymyxins versus aminoglycosides described no clear differences between groups in the proportion of participants with P aeruginosa eradication (OR 1.40. 95% CI 0.36 to 5.35; very low-quality evidence) or improvement in sputum purulence (OR 0.16, 95% CI 0.01 to 3.85; very low-quality evidence). The evidence for changes in FEV₁ was inconclusive. Two of three trials reported adverse events but did not report the proportion of participants experiencing one or more adverse events, so we were unable to interpret the information. AUTHORS' CONCLUSIONS Limited low-quality evidence favours short-term oral fluoroquinolones over beta-lactam antibiotics for patients hospitalised with exacerbations. Very low-quality evidence suggests no benefit from inhaled aminoglycosides verus polymyxins. RCTs have presented no evidence comparing other modes of delivery for each of these comparisons, and no RCTs have included children. Overall, current evidence from a limited number of head-to-head trials in adults or children with bronchiectasis is insufficient to guide the selection of antibiotics for short-term or long-term therapy. More research on this topic is needed.

Abstract
INTRODUCTION Non-cystic fibrosis bronchiectasis (NCFB) results from a permanent and progressive destruction of the airways leading to poor lung function. NCFB is characterized by recurrent lung infection, sputum production, and cough, often requiring long-term antibiotic therapy and hospitalization. At present, there are no approved therapies available. Clinical trials of inhaled antibiotics have shown promise against sputum bacterial load, but mixed results on clinical outcomes. Areas covered: The objective of this review is to provide an overview of NCFB and critically evaluate the evidence supporting the outcome measures used in recent clinical trials of inhaled antibiotics. These include quantitative changes in bacterial load, sputum purulence and yield, inflammatory markers, and lung function, as well as clinical changes in exacerbations, exacerbation frequency, hospitalizations, and health-related quality of life. Expert commentary: Recently completed large trials of inhaled antibiotics in NCFB did not consistently meet pre-specified end points, suggesting that we have not yet found the best enrollment criteria or outcome measures to evaluate efficacy, although reduced exacerbation frequency may be clinically most meaningful. Future trials may focus on specific patient populations at high risk with new information obtained through analyses of large international patient registries.

Abstract
BACKGROUND Bronchiectasis is a chronic airway disease characterised by a destructive cycle of recurrent airway infection, inflammation and tissue damage. Antibiotics are a main treatment for bronchiectasis. The aim of continuous therapy with prophylactic antibiotics is to suppress bacterial load, but bacteria may become resistant to the antibiotic, leading to a loss of effectiveness. On the other hand, intermittent prophylactic antibiotics, given over a predefined duration and interval, may reduce antibiotic selection pressure and reduce or prevent the development of resistance. This systematic review aimed to evaluate the current evidence for studies comparing continuous versus intermittent administration of antibiotic treatment in bronchiectasis in terms of clinical efficacy, the emergence of resistance and serious adverse events. OBJECTIVES To evaluate the effectiveness of continuous versus intermittent antibiotics in the treatment of adults and children with bronchiectasis, using the primary outcomes of exacerbations, antibiotic resistance and serious adverse events. SEARCH METHODS On 1 August 2017 and 4 May 2018 we searched the Cochrane Airways Review Group Specialised Register (CAGR), CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, and AMED. On 25 September 2017 and 4 May 2018 we also searched www.clinicaltrials.gov, the World Health Organization (WHO) trials portal, conference proceedings and the reference lists of existing systematic reviews. SELECTION CRITERIA We planned to include randomised controlled trials (RCTs) of adults or children with bronchiectasis that compared continuous versus intermittent administration of long-term prophylactic antibiotics of at least three months' duration. We considered eligible studies reported as full-text articles, as abstracts only and unpublished data. DATA COLLECTION AND ANALYSIS Two review authors independently screened the search results and full-text reports. MAIN RESULTS We identified 268 unique records. Of these we retrieved and examined 126 full-text reports, representing 114 studies, but none of these studies met our inclusion criteria. AUTHORS' CONCLUSIONS No randomised controlled trials have compared the effectiveness and risks of continuous antibiotic therapy versus intermittent antibiotic therapy for bronchiectasis. High-quality clinical trials are needed to establish which of these interventions is more effective for reducing the frequency and duration of exacerbations, antibiotic resistance and the occurrence of serious adverse events.

Abstract
BACKGROUND Bronchiectasis is a chronic respiratory disease characterised by abnormal and irreversible dilatation and distortion of the smaller airways. Bacterial colonisation of the damaged airways leads to chronic cough and sputum production, often with breathlessness and further structural damage to the airways. Long-term macrolide antibiotic therapy may suppress bacterial infection and reduce inflammation, leading to fewer exacerbations, fewer symptoms, improved lung function, and improved quality of life. Further evidence is required on the efficacy of macrolides in terms of specific bacterial eradication and the extent of antibiotic resistance. OBJECTIVES To determine the impact of macrolide antibiotics in the treatment of adults and children with bronchiectasis. SEARCH METHODS We identified trials from the Cochrane Airways Trials Register, which contains studies identified through multiple electronic searches and handsearches of other sources. We also searched trial registries and reference lists of primary studies. We conducted all searches on 18 January 2018. SELECTION CRITERIA We included randomised controlled trials (RCTs) of at least four weeks' duration that compared macrolide antibiotics with placebo or no intervention for the long-term management of stable bronchiectasis in adults or children with a diagnosis of bronchiectasis by bronchography, plain film chest radiograph, or high-resolution computed tomography. We excluded studies in which participants had received continuous or high-dose antibiotics immediately before enrolment or before a diagnosis of cystic fibrosis, sarcoidosis, or allergic bronchopulmonary aspergillosis. Our primary outcomes were exacerbation, hospitalisation, and serious adverse events. DATA COLLECTION AND ANALYSIS Two review authors independently screened the titles and abstracts of 103 records. We independently screened the full text of 40 study reports and included 15 trials from 30 reports. Two review authors independently extracted outcome data and assessed risk of bias for each study. We analysed dichotomous data as odds ratios (ORs) and continuous data as mean differences (MDs) or standardised mean differences (SMDs). We used standard methodological procedures as expected by Cochrane. MAIN RESULTS We included 14 parallel-group RCTs and one cross-over RCT with interventions lasting from 8 weeks to 24 months. Of 11 adult studies with 690 participants, six used azithromycin, four roxithromycin, and one erythromycin. Four studies with 190 children used either azithromycin, clarithromycin, erythromycin, or roxithromycin.We included nine adult studies in our comparison between macrolides and placebo and two in our comparison with no intervention. We included one study with children in our comparison between macrolides and placebo and one in our comparison with no intervention.In adults, macrolides reduced exacerbation frequency to a greater extent than placebo (OR 0.34, 95% confidence interval (CI) 0.22 to 0.54; 341 participants; three studies; I2 = 65%; moderate-quality evidence). This translates to a number needed to treat for an additional beneficial outcome of 4 (95% CI 3 to 8). Data show no differences in exacerbation frequency between use of macrolides (OR 0.31, 95% CI 0.08 to 1.15; 43 participants; one study; moderate-quality evidence) and no intervention. Macrolides were also associated with a significantly better quality of life compared with placebo (MD -8.90, 95% CI -13.13 to -4.67; 68 participants; one study; moderate-quality evidence). We found no evidence of a reduction in hospitalisations (OR 0.56, 95% CI 0.19 to 1.62; 151 participants; two studies; I2 = 0%; low-quality evidence), in the number of participants with serious adverse events, including pneumonia, respiratory and non-respiratory infections, haemoptysis, and gastroenteritis (OR 0.49, 95% CI 0.20 to 1.23; 326 participants; three studies; I2 = 0%; low-quality evidence), or in the number experiencing adverse events (OR 0.83, 95% CI 0.51 to 1.35; 435 participants; five studies; I2 = 28%) in adults with macrolides compared with placebo.In children, there were no differences in exacerbation frequency (OR 0.40, 95% CI 0.11 to 1.41; 89 children; one study; low-quality evidence); hospitalisations (OR 0.28, 95% CI 0.07 to 1.11; 89 children; one study; low-quality evidence), serious adverse events, defined within the study as exacerbations of bronchiectasis or investigations related to bronchiectasis (OR 0.43, 95% CI 0.17 to 1.05; 89 children; one study; low-quality evidence), or adverse events (OR 0.78, 95% CI 0.33 to 1.83; 89 children; one study), in those receiving macrolides compared to placebo. The same study reported an increase in macrolide-resistant bacteria (OR 7.13, 95% CI 2.13 to 23.79; 89 children; one study), an increase in resistance to Streptococcus pneumoniae (OR 13.20, 95% CI 1.61 to 108.19; 89 children; one study), and an increase in resistance to Staphylococcus aureus (OR 4.16, 95% CI 1.06 to 16.32; 89 children; one study) with macrolides compared with placebo. Quality of life was not reported in the studies with children. AUTHORS' CONCLUSIONS Long-term macrolide therapy may reduce the frequency of exacerbations and improve quality of life, although supporting evidence is derived mainly from studies of azithromycin, rather than other macrolides, and predominantly among adults rather than children. However, macrolides should be used with caution, as limited data indicate an associated increase in microbial resistance. Macrolides are associated with increased risk of cardiovascular death and other serious adverse events in other populations, and available data cannot exclude a similar risk among patients with bronchiectasis.

Abstract
Non-cystic fibrosis bronchiectasis (NCFBE) is a rare, chronic lung disease characterized by bronchial inflammation and permanent airway dilation. Chronic infections with P. aeruginosa have been linked to higher morbidity and mortality. To understand the impact of P. aeruginosa in NCFBE on health care costs and burden, we assessed healthcare costs and utilization before and after P. aeruginosa diagnosis. Using data from 2007 to 2013 PharMetrics Plus administrative claims, we included patients with ≥2 claims for bronchiectasis and >1 claim for P. aeruginosa; then excluded those with a claim for cystic fibrosis. Patients were indexed at first claim for P. aeruginosa and were required to have >12 months before and after the index P. aeruginosa. The mean differences in utilization and costs were assessed using paired Student's t-tests for statistical significance. Mean total healthcare costs per patient were $36,213 pre-P. aeruginosa diagnosis versus $67,764 post-P. aeruginosa, an increase of 87% (p < 0.0001). Inpatient costs represented the largest proportion of total healthcare costs post-P. aeruginosa (54%) with an increase of four hospitalizations per patient (p < 0.0001). NCFBE patients with evidence of P. aeruginosa incur substantially greater healthcare costs and utilization after P. aeruginosa diagnosis. Future research should explore methods of earlier identification of NCFBE patients with P. aeruginosa, as this may lead to fewer severe exacerbations, thereby resulting in a reduction in hospitalizations and healthcare costs.

Abstract
BACKGROUND Home-based pulmonary rehabilitation is a promising intervention that may help patients to overcome the barriers to undergoing pulmonary rehabilitation. However, home-based pulmonary rehabilitation has not yet been investigated in patients with bronchiectasis. OBJECTIVES To investigate the effects of home-based pulmonary rehabilitation in patients with bronchiectasis. METHODS An open-label, randomized controlled trial with 48 adult patients with bronchiectasis will be conducted. INTERVENTIONS The program will consist of three sessions weekly over a period of 8 weeks. Aerobic exercise will consist of stepping on a platform for 20min (intensity: 60-80% of the maximum stepping rate in incremental step test). Resistance training will be carried out using an elastic band for the following muscles: quadriceps, hamstrings, deltoids, and biceps brachii (load: 70% of maximum voluntary isometric contraction). CONTROL The patients will receive an educational manual and a recommendation to walk three times a week for 30min. All patients will receive a weekly phone call to answer questions and to guide the practice of physical activity. The home-based pulmonary rehabilitation group also will receive a home visit every 15 days. MAIN OUTCOME MEASURES incremental shuttle walk test, quality of life, peripheral muscle strength, endurance shuttle walk test, incremental step test, dyspnea, and physical activity in daily life. The assessments will be undertaken at baseline, after the intervention, and 8 months after randomization. DISCUSSION The findings of this study will determine the clinical benefits of home-based pulmonary rehabilitation and will contribute to future guidelines for patients with bronchiectasis.

Abstract
OBJECTIVES Despite its low prevalence, cystic fibrosis (CF) may have a considerable impact on healthcare system expenditures in terms of direct healthcare costs and lost productivity. This study was aimed at calculation of costs associated with CF treatment in Poland, as well as at comparison of average costs of treatment of CF patients in selected countries, taking into account the purchasing power parity. STUDY DESIGN Retrospective study. METHODS The researchers undertook a retrospective study of adult patients with CF taking into account the broadest social perspective possible. Medical and non-medical direct costs as well as indirect costs were calculated. CF costs estimated by researchers from other countries over the last 15 years were also compared. RESULTS Total annual treatment cost per one CF patient in Poland was on average EUR 19,581.08. Costs of treatment of CF patients over the last 15 years varied between the countries and ranged from EUR 23,330.82 in Bulgaria to EUR 68,696.42 in the United States. CONCLUSIONS CF is an international problem. The data in this study could be the baseline for integrated and harmonised approaches for periodical assessment of the future impact of new public policies and interventions for rare diseases at the national and international levels.

Abstract
Introduction Giant cell arteritis (GCA) is a chronic vasculitis affecting approximately 230,000 Americans. Limited data exist on the healthcare resource utilization and costs attributable to GCA. The objective of this study was to estimate the cost of illness in patients with GCA in the US. Methods A cohort of patients with a new GCA diagnosis was identified from a large US claims database between 1 January 2008 and 31 December 2012. Newly diagnosed GCA patients were defined by two claims with GCA (ICD-9 446.5) as one of the listed diagnoses during the study period and no GCA diagnosis in the 12 months prior. Subjects without a GCA diagnosis were matched 5:1 to cases. One-year healthcare costs were compared among cases and controls, adjusting for covariates using generalized linear models. Results A cohort of 1293 GCA patients and 6465 controls was identified. The mean age was 73 years, and 69% were females. Mean Charlson Comorbidity Index was 1.9 for GCA patients and 1.0 for controls. Mean 1-year cost for GCA patients was $34,065 [standard deviation (SD) $52,411], and mean 1-year cost for controls was $12,890 (SD $37,345). After multivariate adjustment, the difference in 1-year cost between GCA patients and controls was $16,431 (95% CI $13,821–$19,041). Conclusions Patients with GCA experience substantially higher healthcare costs in the first year following diagnosis compared to patients without GCA. These results add to the limited evidence available to inform researchers, clinicians, and policymakers on the cost burden of GCA in the US. Funding Genentech Inc.

Abstract
Respiration and gas exchange require coordination between the chest wall, lungs, central nervous system, and pulmonary circulation. A disruption within any one of these systems or a change in the relationship between systems can result in impairments of ventilation, perfusion, or gas exchange. These disruptions can result in debilitating acute and chronic respiratory disorders. This chapter discusses the etiology, epidemiology, clinical presentation, diagnostic criteria, management, and notable public health implications of respiratory system disorders not addressed in prior chapters. Topic areas covered include acute respiratory distress syndrome (ARDS), pulmonary hypertension, pneumothorax, pleural effusion, interstitial lung disease, bronchiectasis, atelectasis, and pulmonary sarcoidosis.

Abstract
BACKGROUND Patients with bronchiectasis often have concurrent comorbidities, but the nature, prevalence, and impact of these comorbidities on disease severity and outcome are poorly understood. We aimed to investigate comorbidities in patients with bronchiectasis and establish their prognostic value on disease severity and mortality rate. METHODS An international multicentre cohort analysis of outpatients with bronchiectasis from four European centres followed up for 5 years was done for score derivation. Eligible patients were those with bronchiectasis confirmed by high-resolution CT and a compatible clinical history. Comorbidity diagnoses were based on standardised definitions and were obtained from full review of paper and electronic medical records, prescriptions, and investigator definitions. Weibull parametric survival analysis was used to model the prediction of the 5 year mortality rate to construct the Bronchiectasis Aetiology Comorbidity Index (BACI). We tested the BACI as a predictor of outcomes and explored whether the BACI added further prognostic information when used alongside the Bronchiectasis Severity Index (BSI). The BACI was validated in two independent international cohorts from the UK and Serbia. FINDINGS Between June 1, 2006, and Nov 22, 2013, 1340 patients with bronchiectasis were screened and 986 patients were analysed. Patients had a median of four comorbidities (IQR 2-6; range 0-20). 13 comorbidities independently predicting mortality rate were integrated into the BACI. The overall hazard ratio for death conferred by a one-point increase in the BACI was 1·18 (95% CI 1·14-1·23; p<0·0001). The BACI predicted 5 year mortality rate, hospital admissions, exacerbations, and health-related quality of life across all BSI risk strata (p<0·0001 for mortality and hospital admissions, p=0·03 for exacerbations, p=0·0008 for quality of life). When used in conjunction with the BSI, the combined model was superior to either model alone (p=0·01 for combined vs BACI; p=0·008 for combined vs BSI). INTERPRETATION Multimorbidity is frequent in bronchiectasis and can negatively affect survival. The BACI complements the BSI in the assessment and prediction of mortality and disease outcomes in patients with bronchiectasis. FUNDING European Bronchiectasis Network (EMBARC).

Abstract
Bronchiectasis is a chronic airway infection syndrome, distinct from cystic fibrosis that is rising in prevalence and is associated with significant morbidity and mortality. It can be caused by many etiologies including post-infectious effects or be seen in common lung diseases such as chronic obstructive pulmonary disease (COPD) or severe asthma. Bronchiectasis is associated with many Aspergillus-associated syndromes: allergic bronchopulmonary aspergillosis (ABPA) may complicate asthma, thus leading to bronchiectasis as part of the diagnostic criteria of ABPA or can complicate preexisting bronchiectasis due to another etiology. Aspergilloma can develop in areas of lung damage seen in patients with bronchiectasis, whereas fungal bronchitis may lead to later bronchiectasis. Invasive aspergillosis, perhaps more commonly viewed as a consequence of significant immunosuppression, is also seen in the absence of immunosuppression in those with underlying lung diseases including bronchiectasis. The pathogenesis and treatments of these diverse Aspergillus-associated diseases in bronchiectasis are discussed.

Abstract
OBJECTIVE To analyze changes in the incidence, diagnostic procedures, comorbidity, length of hospital stay (LOHS), costs and in-hospital mortality (IHM) for patients with bronchiectasis who were hospitalized in Spain over a 10-year period. METHODS We included all admissions for patients diagnosed with bronchiectasis as primary or secondary diagnosis during 2004-2013. RESULTS 282,207 patients were admitted to the study. After controlling for possible confounders, we observed a significant increase in the incidence of hospitalizations over the study period when bronchiectasis was a secondary diagnosis. When bronchiectasis was the primary diagnosis we observed a significant decline in the incidence. In all cases, this pathology was more frequent in males, and the average age and comorbidity increased significantly during the study period (p<0.001). When bronchiectasis was the primary diagnosis, the most frequent secondary diagnosis was Pseudomonas aeruginosa infection. When bronchiectasis was the secondary diagnosis, the most frequent primary diagnosis was COPD. IHM was low, tending to decrease from 2004 to 2013 (p<0.05). The average LOHS decreased significantly during the study period in both cases (p<0.001). The mean cost per patient decreased in patients with bronchiectasis as primary diagnosis, but it increased for cases of bronchiectasis as secondary diagnosis (p<0.001). CONCLUSIONS Our results reveal an increase in the incidence of hospital admissions for patients with bronchiectasis as a secondary diagnosis from 2004 to 2013, as opposed to cases of bronchiectasis as the primary diagnosis. Although the average age and comorbidity significantly increased over time, both IHM and average LOHS significantly decreased.

Abstract
Patients with bronchiectasis (BE) present exacerbations that increase with severity of the disease. We aimed to determine the annual cost of BE treatment according to its severity, determined by FACED score, as well as the parameters associated with higher costs. Multicentre historical cohorts study with patients from six hospitals in Spain. The costs arising during the course of a year from maintenance treatment, exacerbations, emergency visits and hospital admissions were analysed. In total, 456 patients were included (56.4% mild BE, 26.8% moderate BE and 16.9% severe BE). The mean cost was €4671.9 per patient, which increased significantly with severity. In mild BE, most of the costs were due to bronchodilators and inhaled steroids; in severe BE, most were due to exacerbations and inhaled antibiotics. Forced expiratory volume in 1 second (FEV1%), age, colonization by Pseudomonas aeruginosa and the number of admissions were independently related to higher costs. The highest costs were found in patients with BE associated with chronic obstructive pulmonary disease, with the most exacerbations and with chronic bronchial colonization by Pseudomonas aeruginosa (PA). In conclusion, BE patients gave rise to high annual costs, and these were doubled on each advance in severity on the FACED score. FEV1%, age, colonization by PA and the number of admissions were independently related to higher costs.

Abstract
Gram-negative organisms comprise a large portion of the pathogens responsible for lower respiratory tract infections, especially those that are nosocomially acquired, and the rate of antibiotic resistance among these organisms continues to rise. Systemically administered antibiotics used to treat these infections often have poor penetration into the lung parenchyma and narrow therapeutic windows between efficacy and toxicity. The use of inhaled antibiotics allows for maximization of target site concentrations and optimization of pharmacokinetic/pharmacodynamic indices while minimizing systemic exposure and toxicity. This review is a comprehensive discussion of formulation and drug delivery aspects, in vitro and microbiological considerations, pharmacokinetics, and clinical outcomes with inhaled antibiotics as they apply to disease states other than cystic fibrosis. In reviewing the literature surrounding the use of inhaled antibiotics, we also highlight the complexities related to this route of administration and the shortcomings in the available evidence. The lack of novel anti-Gram-negative antibiotics in the developmental pipeline will encourage the innovative use of our existing agents, and the inhaled route is one that deserves to be further studied and adopted in the clinical arena.

Abstract
Background This study aimed to determine the societal economic burden and health-related quality of life (HRQOL) of cystic fibrosis (CF) patients in the UK. Methods A bottom-up cost-of-illness, cross-sectional, retrospective analysis of 74 patients was conducted aiming to estimate the economic impact of CF. Data on demographic characteristics, health resource utilisation, informal care, productivity losses and HRQOL were collected from questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D) instrument. Results Using unit costs for 2012 we found that the average annual cost for a CF patient was €48,603, with direct health care costs amounting to €20,854 (42.9 % of total costs), direct non-health care costs being €21,528 (44.3 %) and indirect costs attributable to productivity losses being €6,222 (12.8 %). On average, the largest expenditures by far were accounted for by informal care (44.1 %), followed by medications (14.5 %), acute hospitalisations (13.9 %), early retirement (9.1 %) and outpatient and primary health care visits (7.9 %). Sharp differences existed depending on whether CF patients were in need of caregiver help (€76,271 versus €26,335). In adult CF patients, mean EQ-5D index scores were 0.64 (0.93 in the general population) and mean EQ-5D visual analogue scale scores were 62.23 (86.84 in the general population); among caregivers, these scores were 0.836 and 80.85, respectively. Discussion Our analysis highlights the importance of the economic and quality of life consequences of CF from a societal perspective. The results highlight that beyond conventional costs such as acute hospitalisations, medication and outpatient and primary care visits, indirect costs related to informal care and early retirement, have significant societal implications. Similarly, our analysis showed that the average EQ-5D index score of adult CF patients was significantly lower than in the general population, an indication that a methodological bias may exist in using the latter in economic analyses. Conclusion CF poses a significant cost burden on UK society, with non-health care and indirect costs representing 57 % of total average costs, and HRQOL being considerably lower than in the general population.

Abstract
PURPOSE OF REVIEW In 2010, the British Thoracic Society published a guideline for the care of patients with noncystic fibrosis (non-CF) bronchiectasis; other recent clinical review articles and original scientific manuscripts have also studied the use of antibiotics in bronchiectasis. This review will summarize the current literature on the indications and options for antibiotic treatment in bronchiectasis. RECENT FINDINGS Since 2012, a number of manuscripts have been published that provide evidence to support the use of antibiotics in non-CF bronchiectasis, including macrolide antibiotics, inhaled aminoglycosides and inhaled fluoroquinolone therapies. However, data remain preliminary and there are phase 3 trials underway to further investigate the efficacy and safety of antibiotics in non-CF bronchiectasis. SUMMARY Although there are currently no U.S. Food and Drug Administration (FDA)-approved antibiotics for the treatment of patients with bronchiectasis, this review will highlight the current state of the science with regard to antibiotics that may be effective in non-CF bronchiectasis as well as highlighting those in development to treat this complex disease.
