Abstract
Background Bronchiectasis is a chronic lung disease characterized by permanent bronchial wall dilatation. Although it has been known as an orphan disease, it has recently gained attention because of registry-based studies and drug research. Aims We aimed to use a multicenter database to analyze and compare data regarding the etiology, associated comorbidities, microbiological characteristics, and preventive strategies of bronchiectasis in Türkiye to those of other countries. Study Design A multicenter prospective cohort study. Methods The multicenter, prospective cohort study was conducted between March 2019 and January 2022 using the Turkish Adult Bronchiectasis Database, in which 25 centers in Türkiye participated. Patients aged > 18 years who presented with respiratory symptoms such as cough, sputum, and dyspnea and were diagnosed with non-cystic fibrosis bronchiectasis using computed tomography were included in the study. Demographic information, etiologies, comorbidities, pulmonary functions, and microbiological, radiological, and clinical data were collected from the patients. Results Of the 1,035 study participants, 518 (50%) were females. The mean age of the patients was 56.1 ± 16.1 years. The underlying etiology was detected in 565 (54.6%) patients. While postinfectious origin was the most common cause of bronchiectasis (39.5%), tuberculosis was identified in 11.3% of the patients. An additional comorbidity was detected in 688 (66.5%) patients. The most common comorbidity was cardiovascular disease, and chronic obstructive pulmonary disease (COPD) and bronchiectasis was identified in 19.5% of the patients. The most commonly detected microbiological agent was Pseudomonas aeruginosa (29.4%). Inhaled corticosteroids (ICS) were used in 70.1% of the patients, and the frequency of exacerbations in the last year was significantly higher in patients using ICS than in nonusers (p < 0.0001). Age [odds ratio (OR): 1.028; 95% confidence interval (CI): 1.005-1.051], cachexia (OR: 4.774; 95% CI: 2,054-11,097), high modified medical research council dyspnea scale score (OR: 1,952; 95% CI: 1,459-2,611), presence of chronic renal failure (OR: 4,172; 95% CI: 1,249-13,938) and use of inhaled steroids (OR: 2,587; 95% CI: 1,098-6,098) were significant risk factors for mortality. Mortality rates were higher in patients with COPD than in those with no COPD (21.7-9.1%, p = 0.016). Patients with bronchiectasis and COPD exhibited more frequent exacerbations, exacerbation-related hospitalizations, and hospitalization in the intensive care unit in the previous year than patients without COPD. Conclusion This is the first multicenter study of bronchiectasis in Türkiye. The study results will provide important data that can guide the development of health policies in Türkiye on issues such as infection control, vaccination, and the unnecessary use of antibiotics and steroids.

Abstract
BACKGROUND Improving health-related quality of life (HRQOL) has emerged as a priority in the management of nontuberculous mycobacterial pulmonary disease (NTM-PD). We aimed to evaluate HRQOL and its changes after 6 months' treatment in patients with NTM-PD. METHODS The NTM-KOREA is a nationwide prospective cohort enrolling patients initiating treatment for NTM-PD in 8 institutions across South Korea. We conducted the Quality of Life-Bronchiectasis (QOL-B) at 6-month intervals and evaluated baseline scores (higher scores indicate better quality of life) and changes after 6 months' treatment. Multivariate logistic regression was performed to identify factors associated with improvement in the QOL-B physical functioning and respiratory symptoms domains. RESULTS Between February 2022 and August 2023, 411 patients were included in the analysis. Baseline scores (95% confidence interval [CI]) for physical functioning and respiratory symptoms were 66.7 (46.7-86.7) and 81.5 (70.4-92.6), respectively. Among 228 patients who completed the QOL-B after 6 months' treatment, improvements in physical functioning and respiratory symptoms were observed in 61 (26.8%) and 71 (31.1%) patients, respectively. A lower score (adjusted odds ratio; 95% CI) for physical functioning (0.93; 0.91-0.96) and respiratory symptoms (0.92; 0.89-0.95) at treatment initiation was associated with a greater likelihood of physical functioning and respiratory symptom improvement, respectively; achieving culture conversion was not associated with improvement in physical functioning (0.62; 0.28-1.39) or respiratory symptoms (1.30; 0.62-2.74). CONCLUSIONS After 6 months of antibiotic treatment for NTM-PD, HRQOL improved in almost one-third, especially in patients with severe initial symptoms, regardless of culture conversion. CLINICAL TRIALS REGISTRATION ClinicalTrials.gov identifier: NCT03934034.

Abstract
BACKGROUND A validated 4-point sputum colour chart can be used to objectively evaluate the levels of airway inflammation in bronchiectasis patients. In the European Bronchiectasis Registry (EMBARC), we tested whether sputum colour would be associated with disease severity and clinical outcomes. METHODS We used a prospective, observational registry of adults with bronchiectasis conducted in 31 countries. Patients who did not produce spontaneous sputum were excluded from the analysis. The Murray sputum colour chart was used at baseline and at follow-up visits. Key outcomes were frequency of exacerbations, hospitalisations for severe exacerbations and mortality during up to 5-year follow-up. RESULTS 13 484 patients were included in the analysis. More purulent sputum was associated with lower forced expiratory volume in 1 s (FEV1), worse quality of life, greater bacterial infection and a higher bronchiectasis severity index. Sputum colour was strongly associated with the risk of future exacerbations during follow-up. Compared to patients with mucoid sputum (reference group), patients with mucopurulent sputum experienced significantly more exacerbations (incident rate ratio (IRR) 1.29, 95% CI 1.22-1.38; p<0.0001), while the rates were even higher for patients with purulent (IRR 1.55, 95% CI 1.44-1.67; p<0.0001) and severely purulent sputum (IRR 1.91, 95% CI 1.52-2.39; p<0.0001). Hospitalisations for severe exacerbations were also associated with increasing sputum colour with rate ratios, compared to patients with mucoid sputum, of 1.41 (95% CI 1.29-1.56; p<0.0001), 1.98 (95% CI 1.77-2.21; p<0.0001) and 3.05 (95% CI 2.25-4.14; p<0.0001) for mucopurulent, purulent and severely purulent sputum, respectively. Mortality was significantly increased with increasing sputum purulence, hazard ratio 1.12 (95% CI 1.01-1.24; p=0.027), for each increment in sputum purulence. CONCLUSION Sputum colour is a simple marker of disease severity and future risk of exacerbations, severe exacerbations and mortality in patients with bronchiectasis.

Abstract
Introduction: Patients with chronic lung disease (CLD) experience a heavy symptom burden at the end of life, but their uptake of palliative care is notably low. Having an understanding of a patient's prognosis would facilitate shared decision making on treatment options and care planning between patients, families, and their clinicians, and complement clinicians' assessments of patients' unmet palliative needs. While literature on prognostication in patients with chronic obstructive pulmonary disease (COPD) has been established and summarized, information for other CLDs remains less consolidated. Summarizing the mortality risk factors for non-COPD CLDs would be a novel contribution to literature. Hence, we aimed to identify and summarize the prognostic factors associated with non-COPD CLDs from the literature. Methods: We conducted a scoping review following published guidelines. We searched MEDLINE, Embase, PubMed, CINAHL, Cochrane Library, and Web of Science for studies published between 2000 and 2020 that described non-COPD CLD populations with an all-cause mortality risk period of up to three years. Only primary studies which reported associations with mortality adjusted through multivariable analysis were included. Results: Fifty-five studies were reviewed, with 53 based on interstitial lung disease (ILD) or connective tissue disease-associated ILD populations and two in bronchiectasis populations. Prognostic factors were classified into 10 domains, with pulmonary function and disease being the largest. Older age, lower forced vital capacity, and lower carbon monoxide diffusing capacity were most commonly investigated and associated with statistically significant increases in mortality risks. Conclusions: This comprehensive overview of prognostic factors for patients with non-COPD CLDs would facilitate the identification and prioritization of candidate factors to predict short-term mortality, supporting tool development for decision making and to identify high-risk patients for palliative needs assessments. Literature focused on patients with ILDs, and more studies should be conducted on other CLDs to bridge the knowledge gap.

Abstract
BACKGROUND Asthma is commonly reported in patients with a diagnosis of bronchiectasis. OBJECTIVE The aim of this study was to evaluate whether patients with bronchiectasis and asthma (BE+A) had a different clinical phenotype and different outcomes compared with patients with bronchiectasis without concomitant asthma. METHODS A prospective observational pan-European registry (European Multicentre Bronchiectasis Audit and Research Collaboration) enrolled patients across 28 countries. Adult patients with computed tomography-confirmed bronchiectasis were reviewed at baseline and annual follow-up visits using an electronic case report form. Asthma was diagnosed by the local investigator. Follow-up data were used to explore differences in exacerbation frequency between groups using a negative binomial regression model. Survival analysis used Cox proportional hazards regression. RESULTS Of 16,963 patients with bronchiectasis included for analysis, 5,267 (31.0%) had investigator-reported asthma. Patients with BE+A were younger, were more likely to be female and never smokers, and had a higher body mass index than patients with bronchiectasis without asthma. BE+A was associated with a higher prevalence of rhinosinusitis and nasal polyps as well as eosinophilia and Aspergillus sensitization. BE+A had similar microbiology but significantly lower severity of disease using the bronchiectasis severity index. Patients with BE+A were at increased risk of exacerbation after adjustment for disease severity and multiple confounders. Inhaled corticosteroid (ICS) use was associated with reduced mortality in patients with BE+A (adjusted hazard ratio 0.78, 95% CI 0.63-0.95) and reduced risk of hospitalization (rate ratio 0.67, 95% CI 0.67-0.86) compared with control subjects without asthma and not receiving ICSs. CONCLUSIONS BE+A was common and was associated with an increased risk of exacerbations and improved outcomes with ICS use. Unexpectedly we identified significantly lower mortality in patients with BE+A.

Abstract
BACKGROUND Bronchiectasis is a heterogeneous, neglected disease with few multicentre studies exploring the causes, severity, microbiology, and treatment of the disease across Europe. This aim of this study was to describe the clinical characteristics of bronchiectasis and compare between different European countries. METHODS EMBARC is an international clinical research network for bronchiectasis. We report on a multicentre, prospective, observational, non-interventional, cohort study (the EMBARC registry) conducted across 27 European countries and Israel. Comprehensive clinical data were collected from adult patients (aged ≥18 years) at baseline and annual follow-up visits using electronic case report form. Data from individual countries were grouped into four regions (the UK, northern and western Europe, southern Europe, and central and eastern Europe according to modified EU EuroVoc classification). Follow-up data were used to explore differences in exacerbation frequency between regions using a negative binomial regression model. FINDINGS Between Jan 12, 2015, and April 12, 2022, 16 963 individuals were enrolled. Median age was 67 years (IQR 57-74), 10 335 (60·9%) participants were female and 6628 (39·1%) were male. The most common cause of bronchiectasis in all 16 963 participants was post-infective disease in 3600 (21·2%); 6466 individuals (38·1%) were classified as idiopathic. Individuals with bronchiectasis experienced a median of two exacerbations (IQR 1-4) per year and 4483 (26·4%) patients had a hospitalisation for exacerbation in the previous year. When examining the percentage of all isolated bacteria, marked differences in microbiology were seen between countries, with a higher frequency of Pseudomonas aeruginosa and lower Haemophilus influenzae frequency in southern Europe, compared with higher H influenzae in the UK and northern and western Europe. Compared with other regions, patients in central and eastern Europe had more severe bronchiectasis measured by the Bronchiectasis Severity Index (51·3% vs 35·1% in the overall cohort) and more exacerbations leading to hospitalisations (57·9% vs 26·4% in the overall cohort). Overall, patients in central and eastern Europe had an increased frequency of exacerbations (adjusted rate ratio [RR] 1·12, 95% CI 1·01-1·25) and a higher frequency of exacerbations leading to hospitalisations (adjusted RR 1·71, 1·44-2·02) compared with patients in other regions. Treatment of bronchiectasis was highly heterogeneous between regions. INTERPRETATION Bronchiectasis shows important geographical variation in causes, microbiology, severity, and outcomes across Europe.

Abstract
BACKGROUND Long term macrolide treatment has been found beneficial in bronchiectasis (BE) -pathogical bronchial dilatation- possibly due to a combined anti-bacterial and immunomodulatory effect. The exact mechanism of inflammatory response is unknown. Here, we investigated the effect of maintenance macrolide treatment on the inflammatory response in BE. In addition, we assessed the inflammatory profile in BE in relation to disease severity. METHODS During the BAT randomized controlled trial (investigating the effect of 1 year of azithromycin (AZM) in 83 BE patients), data on BE severity, lung function and sputum microbiology was collected. For the current study, a wide range of inflammatory markers were analysed in 3- monthly sputum samples in all participants. RESULTS At baseline, marked neutrophilic but also eosinophilic inflammation was present in both groups, which remained stable throughout the study and was not affected by AZM treatment. Significant upregulation of pro-inflammatory markers correlated with FEV1 < 50% (TNFα, ECP, IL-21, IL-1, p = 0.01- 0.05), H. influenzae (HI) colonization (MPO, ECP, MIP-1, TNFα, IL-21, Il-8, IL-1, IL-1α, p < 0.001 - 0.04) and number of exacerbations (MPO, ECP, VEGF, MMP-9, p = 0.003 - 0.01). Surprisingly, colonization with P. aeruginosa (PA) was found to correlate with an attenuated inflammatory response compared to non-PA colonized. In placebo-treated patients, presence of an infectious exacerbation was reflected by a significant excessive increase in inflammation as compared to a non-significant upregulation in the AZM-treated patients. CONCLUSION One year of AZM treatment did not result in attenuation of the inflammatory response in BE. Increasing disease severity and the presence of an exacerbation were reflected by upregulation of pro-inflammatory markers.

Abstract
Vitamin D is important because it has roles in maintaining musculoskeletal health, redox homeostasis, and the immune system; however, it is commonly dysregulated by endocrine disrupting chemicals, particularly phthalates and bisphenol A (BPA). Continuous exposure to phthalates and BPA may alter the endogenous metabolite profiles associated with vitamin D activity, although the specific metabolites are yet to be identified. In this study, we identified the endogenous metabolites altered by phthalates and BPA exposure through untargeted metabolic profiling and investigated the role of these metabolites in vitamin D activity. Plasma metabolic profiling using liquid chromatography-mass spectrometry was performed in two groups: severe 25-hydroxyvitamin D (25(OH)D) deficiency and high exposure to phthalates and BPA (Group A) and 25(OH)D deficiency and low exposure to phthalates and BPA (Group B). Multivariate analysis revealed a distinct separation between the two groups. A total of six metabolites were annotated, of which levels of two were significantly different between the two groups: platelet-activating factor (PAF) C16 or lysophosphatidylcholine (lysoPC) 18:0, and 11Z-eicosenamide. Plasma levels of PAF C16 or lysoPC 18:0 were increased in Group A and exhibited an area under the curve of 0.769 with an accuracy of 74.4% in a receiver operating characteristic curve analysis. These metabolites are generated as byproducts of lipid peroxidation, which supports the fact that phthalates and BPA induce oxidative stress in cells. Furthermore, PAF C16 and lysoPC 18:0 may be involved in the network that interferes with the antioxidant activity of vitamin D upon exposure to phthalates and BPA. This study results provide useful information on how the activity of vitamin D on the antioxidant system is inhibited when exposure to phthalates and BPA.

Abstract
Bronchiectasis is a heterogenous disease with multiple aetiologies resulting in inflammation and dilatation of the airways with associated mucus production and chronic respiratory infection. The condition is being recognised ever more frequently as the availability of computed tomography increases. It is associated with significant morbidity and healthcare-related costs. With new understanding of the disease process, varying endotypes, identification of underlying causes and treatable traits, the management of bronchiectasis can be increasingly personalised.

Abstract
BACKGROUND Identifying risk factors for poor outcomes can help with risk stratification and targeting of treatment. Risk factors for mortality and exacerbations have been identified in bronchiectasis but have been almost exclusively studied in European and North American populations. This study investigated the risk factors for poor outcome in a large population of bronchiectasis patients enrolled in India. METHODS The European Multicentre Bronchiectasis Audit and Research Collaboration (EMBARC) and Respiratory Research Network of India (EMBARC-India) registry is a prospective observational study of adults with computed tomography-confirmed bronchiectasis enrolled at 31 sites across India. Baseline characteristics of patients were used to investigate associations with key clinical outcomes: mortality, severe exacerbations requiring hospital admission, overall exacerbation frequency and decline in forced expiratory volume in 1 s. RESULTS 1018 patients with at least 12-month follow-up data were enrolled in the follow-up study. Frequent exacerbations (≥3 per year) at baseline were associated with an increased risk of mortality (hazard ratio (HR) 3.23, 95% CI 1.39-7.50), severe exacerbations (HR 2.71, 95% CI 1.92-3.83), future exacerbations (incidence rate ratio (IRR) 3.08, 95% CI 2.36-4.01) and lung function decline. Coexisting COPD, dyspnoea and current cigarette smoking were similarly associated with a worse outcome across all end-points studied. Additional predictors of mortality and severe exacerbations were increasing age and cardiovascular comorbidity. Infection with Gram-negative pathogens (predominantly Klebsiella pneumoniae) was independently associated with increased mortality (HR 3.13, 95% CI 1.62-6.06), while Pseudomonas aeruginosa infection was associated with severe exacerbations (HR 1.41, 95% CI 1.01-1.97) and overall exacerbation rate (IRR 1.47, 95% CI 1.13-1.91). CONCLUSIONS This study identifies risk factors for morbidity and mortality among bronchiectasis patients in India. Identification of these risk factors may support treatment approaches optimised to an Asian setting.

Abstract
BACKGROUND Infection by SARS-CoV-2 has unquestionably had an impact on the health of patients with chronic respiratory airway diseases, such as COPD and asthma, but little information is available about its impact on patients with bronchiectasis. The objective of the present study was to analyze the effect of the SARS-CoV-2 pandemic on the state of health, characteristics, and clinical severity (including the number and severity of exacerbations) of patients with non-cystic fibrosis bronchiectasis. METHODS This study was multicenter, observational, and ambispective (with data collected before and during the SARS-CoV-2 pandemic), and included 150 patients diagnosed with non-cystic fibrosis bronchiectasis. RESULTS A significant drop was observed in the number and severity of the exacerbations (57% in all exacerbations and 50% in severe exacerbations) in the E-FACED and BSI multidimensional scores, in the pandemic, compared with the pre-pandemic period. There was also a drop in the percentage of sputum samples positive for pathogenic microorganisms in general (from 58% to 44.7%) and, more specifically, Pseudomonas aeruginosa (from 23.3% to 13.3%) and Haemophilus influenzae (from 21.3% to 14%). CONCLUSIONS During the SARS-CoV-2 period, a significant reduction was observed in the exacerbations, severity, and isolations of pathogenic microorganisms in patients with bronchiectasis.

Abstract
Purpose Patients with bronchiectasis (BE) who suffer frequent exacerbations are likely to experience negative effects on quality of life (QoL) and require more healthcare utilization. We aimed to discover, in a cohort of Finnish BE patients, those risk factors that influence QoL. Methods Non-cystic fibrosis BE patients of a Helsinki University Hospital cohort were examined with high-resolution computed tomography (HRCT) of the chest. They completed a disease-specific quality of life-bronchiectasis (QoL-B) questionnaire in Finnish translation. We considered scores in the lowest quarter (25%) of that QoL-B scale to indicate poor QoL. The bronchiectasis severity index (BSI), FACED score, and modified Medical Research Council (mMRC) dyspnoea scale were used. Results Overall, of 95 adult BE patients, mean age was 69 (SD ± 13) and 79% were women. From the cohort, 82% presented with chronic sputum production and exacerbations, at a median rate of 1.7 (SD ± 1.6). The number of exacerbations (OR 1.7), frequent exacerbations (≥3 per year) (OR 4.9), high BSI score (OR 1.3), and extensive disease (≥3 lobes) (OR 3.7) were all predictive of poor QoL. Frequent exacerbations were associated with bronchial bacterial colonisation, low forced expiratory volume in 1 s (FEV1), and radiological disease severity. Based on the BSI, 34.1% of our cohort had severe disease, with 11.6% classified as severe according to their FACED score. The mMRC dyspnoea score (r = −0.57) and BSI (r = −0.60) correlated, in the QoL-B questionnaire, negatively with physical domain. Conclusion The strongest determinants of poor QoL in the cohort of Finnish BE patients were frequent exacerbations, radiological disease severity, and high BSI score. Neither comorbidities nor BE aetiology appeared to affect QoL. Reduced physical capacity correlated with dyspnoea and severe disease.

Abstract
OBJECTIVES Bronchiectasis is a chronic respiratory disease characterized by sputum production, cough, and several bronchial infections. Lung function is an important parameter to evaluate and study in patients with bronchiectasis. This study aimed to evaluate the annual changes in forced expiratory volume in one second (FEV1) and related factors in patients with with noncystic fibrosis bronchiectasis. METHODS A total of 529 patients who were diagnosed as having bronchiectasis using computed tomography and followed at the bronchiectasis unit of the Cerrahpasa Medical Faculty at Istanbul University between 1996 and 2018 were included in this retrospective study. A total of 153 patients were included in the study. RESULTS The mean age of the patients was 58.6 ± 16.8 years and 61% (n = 93) were female. The annual change of FEV1 and forced vital capacity was -39 ± 82 (minimum: -585, maximum: 355, median: -26) mL and - 44 ± 91 (minimum: -517, maximum: 303, median: -31) mL, respectively. There was no correlation in FEV1 decline between those with and without Pseudomonas colonization (P = 0.65). No correlation was found between the etiologic factors and the decline of FEV1. A correlation existed only between the first FEV1 and the decline of FEV1 (for the first FEV1%, P = 0.038 [R = -0.17]; for the first FEV1 [mL] P = 0.026 [R = -0.18]). CONCLUSIONS An annual mean FEV1 loss of 39 mL was found in adult patients with noncystic fibrosis bronchiectasis. The annual mean FEV1 decline was found to be associated with the baseline FEV1 value. Physicians should exercise caution in this regard in patients with bronchiectasis with low FEV1 values.

Abstract
OBJECTIVE The objective of this study was to evaluate the quality of life of patients with noncystic fibrosis bronchiectasis during a 1-year follow-up by using the EuroQol - 5 Dimensions - 3 Levels (EQ-5D-3L) questionnaire. METHODS A cohort study was conducted with 100 patients with noncystic fibrosis bronchiectasis and followed up with face-to-face visits or by telephone contact every 3 months for 1 year. All patients were recruited from a single referral center for bronchiectasis. At the time of recruiting and at the end of 1 year, the EQ-5D-3L questionnaire was applied to evaluate the patients' quality of life. Variables, such as exacerbation, emergency care, comorbidities, hemoptysis, colonization, and hospitalization, were assessed. RESULTS Of the 100 patients, 99 completed the study and 72% were women. There were no marked limitations in the mobility and self-care domains during the follow-up. At the end of the follow-up, 32 patients were extremely anxious or depressed. The quality of life assessed by using EQ-5D-3L had an initial mean score of 0.545 and of 0.589 after 1 year, which was statistically significant (p=0.011). CONCLUSION Patients with noncystic fibrosis bronchiectasis have a poor quality of life, and the EQ-5D-3L questionnaire may be a tool for monitoring patients with bronchiectasis.

Abstract
Bronchiectasis is a radiological diagnosis made using computed tomographic (CT) imaging. Although visual CT assessment is necessary for the diagnosis of bronchiectasis, visual assessment of disease severity and progression is challenging. Computer tools offer the potential to improve the characterization of lung damage in patients with bronchiectasis. Newer imaging techniques such as MRI with hyperpolarized gas inhalation have the potential to identify early forms of disease and are without the constraints of requiring ionizing radiation exposure.

Abstract
Background and objective Many bronchiectasis patients suffer dyspnea, decreased exercise tolerance,
and low body mass index. Chest wall muscles play a special role in
respiratory movement and make up parts of skeletal muscles. This study aimed
to examine the chest wall muscle thickness and their relationship with
disease severity in bronchiectasis. Methods We retrospectively included 166 patients with bronchiectasis and 62 patients
with pneumonia as comparators. The thickness of chest wall muscle as
determined in chest CT, pulmonary function, and Bronchiectasis Severity
Index (BSI) score were recorded. We compared the thickness of the chest wall
muscle in two groups and assessed the relationships among chest wall muscle
thickness, pulmonary function, and BSI score. Results Chest wall muscle thickness of the anterior midclavicular line and posterior
exterior scapula were thinner in bronchiectasis patients than comparators
both above the aortic arch level and at the aortic arch window level. Muscle
thickness of the posterior interior scapula above the aortic arch level was
significantly thinner in bronchiectasis patients. Chest wall muscle
thickness at the anterior midclavicular line both the above aortic arch
level and at the level of the aortic arch window were related to diffuse
capacity in bronchiectasis patients. Anterior chest wall muscle thickness
above the aortic arch was found to be a risk factor of disease severity. Conclusion Anterior chest wall muscles in the upper and middle chest were thinner in
bronchiectasis patients than in comparators, and had relationship with
spirometry and diffuse compacity factors. We provide another method to
conveniently assess bronchiectasis severity.

Abstract
This study aims to investigate the risk factors associated with impaired pulmonary diffusing capacity among patients with noncystic fibrosis bronchiectasis (NCFB) and compare the predictive value of several scoring systems for the impairment in these patients. Between July 2019 and June 2021, patients who were admitted to the hospital and diagnosed with NCFB were included in this study. Clinical data were collected and analyzed retrospectively. A total of 175 NCFB patients were included in the analysis. Multivariate logistic regression analysis revealed that impaired pulmonary diffusing capacity diagnosed by carbon monoxide diffusing capacity (DLCO) <80% prediction was associated with age, Reiff score, body mass index (BMI), comorbid chronic obstructive pulmonary disease (COPD), and interstitial lung disease (ILD). Disease duration, frequency of exacerbation, hemoglobin level, and COPD were independent risk factors for impaired pulmonary diffusing capacity diagnosed by DLCO/alveolar volume (VA) <80% prediction. Age, Reiff score, and smoking status were independent risk factors for decreased VA diagnosed by VA <80% prediction. The areas under the curve (AUC) for discrimination of DLCO <80% prediction were 0.822 (0.760-0.885) for Bronchiectasis Severity Index (BSI), 0.787 (0.718-0.856) for FACED, 0.795 (0.729-0.863) for E-FACED, and 0.767 (0.694-0.839) for modified Medical Research Council (mMRC) scores; the AUC for discrimination of DLCO/VA <80% prediction was 0.803 (0.727-0.880) for BSI, 0.752 (0.669-0.835) for FACED, 0.757 (0.676-0.839) for E-FACED, and 0.762 (0.679-0.845) for mMRC, respectively. The BSI had the largest AUC, but the differences between those scoring systems had no statistical significance (P=0.181 for DLCO <80% prediction and P=0.105 for DLCO/VA <80% prediction). The mMRC score (up to 2 grades) showed a high specificity for discriminating diffusing dysfunction (88.3% for DLCO <80% prediction and 76.1% for DLCO/VA <80% prediction). In NCFB patients, several factors such as age, Reiff score, BMI, exacerbation frequency, disease duration, and comorbid COPD and ILD were associated with impaired pulmonary diffusing capacity, which requires more attention in managing those patients. In addition, several scoring methods, including a simple index of mMRC, showed a comparable and moderate performance for predicting pulmonary diffusing impairment and would facilitate the systematic evaluation of the diffusing capacity of NCFB patients.

Abstract
OBJECTIVE Bronchiectasis is a chronic suppurative lung disease that significantly impacts the patients' quality of life. Aim of this study is to evaluate the relationship between life of quality and patient's psychological status and bronchiectasis disease severity indexes in patients with non-Cystic Fibrosis (CF) bronchiectasis. We also aimed to investigate the validity and reliability of Turkish version of Quality-of-Life Questionnaire-Bronchiectasis (QoL-B V3.1) in Turkish adult bronchiectatic patients. MATERIAL AND METHODS 90 stable non-CF bronchiectatic adult patients were enrolled into this study. At baseline, dyspnea score, BMI, lung function tests, sputum cultures, number of exacerbations and hospital admissions, disease severity indexes were recorded. All of the participants underwent quality of life assessment using both QoL-B V3.1 and of Short-Form (SF)-36 questionnaires, psychological status was evaluated by using HADS (Hospital Anxiety and Depression Scale). RESULTS In all study participants, anxiety was diagnosed in 27/90 (30%) of patients and depression was diagnosed in 37/90 (41%) of patients. Patients with anxiety and depression had lower quality of life scores in various domains (p:0.026-p:0.001) and HADS scores negatively correlated with several quality-of-life domains (r=-0.216 - r=- 0.343). Female patients had higher risk for depression (55% vs 22%, p:0.002) and worse quality of life than males (p:0.016-p:0.038). Several life quality scores of both instruments were worse in patients with moderate-severe disease severity indexes when compared with those of mild groups. Moreover, Turkish version of newly described QoL-B V3.1 questionnaire was found to be reliable and valid instrument to evaluate the quality of life. CONCLUSION These results emphasize the importance of mental health and disease severity as significant determinants of the life quality in patients particularly female patients with non-CF bronchiectasis.

Abstract
Introduction: Noncystic fibrosis bronchiectasis (NCFB) is a neglected debilitating condition with scarce epidemiological literature explaining its geographical heterogeneity, especially in lower and middle-income countries. This study aimed to assess and correlate the functional profile of NCFB patients and evaluate the correlation of body mass index (BMI) with several disease variables. Methods: This mixed-method retrospective research study was conducted on 124 radiologically confirmed NCFB patients in terms of various qualitative and quantitative variables. Results: Restrictive ventilatory defect was the most common type with the preponderance of male former smokers. Mean platelet lymphocyte ratio (PLR; 104.08 ± 73.59) revealed certain degree of systemic inflammatory burden with a slightly higher mean peripheral leukocyte count (10665.19 ± 4268.81 cell/mm3) and eosinophilia of >2%. Almost all patients had periodontal disease with a higher prevalence of chronic periodontitis (54.83%). Moderately severe and predominantly cystic radiological type was encountered with 61.2% patients positive for Pseudomonas aeruginosa. Bronchiectasis aetiology comorbidity index (BACI) i.e., 2.34 ± 2.37 represented an intermediate mortality risk in our patients. On basis of BMI, majority were young underweights with poor pulmonary functions while PLR skewed toward overweight patients (nonsignificant P > 0.05). Forced expiratory volume/forced vital capacity displayed a negative weak moderately significant correlation with BACI (r = −0.24; P = 0.008). Peripheral lymphocyte count demonstrated a weak negative but significant correlation with modified Reiff score (r = −0.20; P = 0.023) while serum neutrophil count had a weak negative moderately significant correlation with hemoglobin (r = −0.20; P = 0.023). Conclusions: NCFB bears great heterogeneity with distinct geographical phenotypes and should be correlated thoroughly in terms of peripheral leukocytes count, pulmonary functions, radiology, BMI, and coexisting comorbidities for adequate management.

Abstract
BACKGROUND The bronchiectasis severity index (BSI) and FACED score are currently used in predicting outcomes of non-cystic fibrosis bronchiectasis (NCFB). Distance-saturation product (DSP), the product of distance walked, and lowest oxygen saturation during the 6-min walk test showed strong predictive power of mortality in non-CF bronchiectasis patients. This study aimed to compare the efficacy of these scores and DSP in predicting mortality. METHODS AND PATIENTS Our retrospective study included NCFB patients from January 2004 to December 2017. We recorded the basic data, pulmonary function, radiologic studies, sputum culture results, acute exacerbations (AE), emergency department (ED) visits, hospitalization, and mortality. RESULTS A total 130 NCFB patients were analysed. The mean BSI score, FACED score, and DSP were 8.8 ± 4.9, 3.4 ± 1.7, and 413.1 ± 101.5 m%, respectively. BSI and FACED scores had comparable predictive power for AE (p=.011; p=.010, respectively). The BSI score demonstrated a significant correlation with ED visits (p=.0003). There were 12 deaths. Patients were stratified using a DSP cut-off value of 345 m% according to the best area under receiver operator characteristic curve (AUC) value in mortality. DSP was not correlated with AE and ED visits. BSI, FACED scores, and DSP demonstrated statistically significant correlations with hospitalization (p<.0001; p<.0001; p=.0007, respectively). The AUC for overall mortality was similar for BSI, FACED score, and DSP (0.80 versus 0.85, p=.491; 0.85 versus 0.83, p=.831). CONCLUSION DSP had comparable predictive power for mortality as the well-validated BSI and FACED scores and is relatively easy to use in clinical practice.KEY MESSAGEDistance-saturation product (DSP) comprised with the product of distance walked, and lowest oxygen saturation during the 6-min walk test, which is common used in clinical practice.DSP demonstrated strong and comparable predictive power of mortality as the well-validated BSI and FACED scores in non-CF bronchiectasis patients.

Abstract
Currently, there is much controversy surrounding the therapeutic approach to pulmonary function abnormalities in patients with bronchiectasis and, consequently, whether and when to use bronchodilators in these patients. National and international guidelines on the treatment of bronchiectasis in adults do not recommend the routine use of bronchodilators because there is no evidence that a significant response to a bronchodilator or the presence or hyperresponsiveness of the airway are good predictors of future effective clinical response. However, some guidelines recommend them in the presence of airway obstruction and/or special conditions, which vary according to the guideline in question, although there are no recommendations on optimal dosing and bronchodilator treatment combined with or without inhaled corticosteroids. Nonetheless, in contrast with guideline recommendations, bronchodilators are overused in real-world patients with bronchiectasis even in the absence of airway obstruction, as demonstrated by analysis of national and international registries. This overuse can be explained by the awareness of the existence of a solid pharmacological rationale that supports the use of bronchodilators in the presence of chronic airway obstruction independent of its aetiology. We performed a systematic review of the literature and were able to verify that there are no randomised controlled trials (apart from a small study with methodological limitations and a very recent trial involving a not-very-large number of patients), or any long-term observational studies on the short- or long-term effect of bronchodilators in patients with bronchiectasis. Therefore, we believe that it is essential and even urgent to evaluate the effects of bronchodilators in these patients with appropriately designed studies.

Abstract
Introduction Bronchiectasis is characterised by excessive neutrophilic inflammation. Lipid mediators such as prostaglandins and leukotrienes have crucial roles in the inflammatory response. Further characterisation of these lipids and understanding the interplay of anti-inflammatory and proinflammatory lipid mediators could lead to the development of novel anti-inflammatory therapies for bronchiectasis. Aim The aim of our study was to characterise the lipids obtained from serum and airways in patients with bronchiectasis in the stable state. Methods Six healthy volunteers, 10 patients with mild bronchiectasis, 15 with moderate bronchiectasis and 9 with severe bronchiectasis were recruited. All participants had 60 mL of blood taken and underwent a bronchoscopy while in the stable state. Lipidomics was done on serum and bronchoalveolar lavage fluid (BALF). Results In the stable state, in serum there were significantly higher levels of prostaglandin E2 (PGE2), 15-hydroxyeicosatetranoic acid (15-HETE) and leukotriene B4 (LTB4) in patients with moderate–severe disease compared with healthy volunteers. There was a significantly lower level of lipoxin A4 (LXA4) in severe bronchiectasis. In BALF, there were significantly higher levels of PGE2, 5-HETE, 15-HETE, 9-hydroxyoctadecadienoic acid and LTB4 in moderate–severe patients compared with healthy volunteers. In the stable state, there was a negative correlation of PGE2 and LTB4 with % predicted forced expiratory volume in 1 s and a positive correlation with antibiotic courses. LXA4 improved blood and airway neutrophil phagocytosis and bacterial killing in patients with bronchiectasis. Additionally LXA4 reduced neutrophil activation and degranulation. Conclusion There is a dysregulation of lipid mediators in bronchiectasis with excess proinflammatory lipids. LXA4 improves the function of reprogrammed neutrophils. The therapeutic efficacy of LXA4 in bronchiectasis warrants further studies.

Abstract
INTRODUCTION Recent randomised clinical trials (RCTs) in Bronchiectasis have failed to reach their primary endpoints, suggesting a need to reassess how we measure treatment response. Exacerbations, quality of life (QOL) and lung function are the most common endpoints evaluated in bronchiectasis clinical trials. We aimed to determine the relationship between responses in terms of reduced exacerbations, improved symptoms and lung function in bronchiectasis. METHODS We evaluated treatment response in 3 RCTs that evaluated mucoactive therapy (inhaled Mannitol), an oral anti-inflammatory/antibiotic (Azithromycin) and an inhaled antibiotic (Aztreonam). Treatment response was defined by absence of exacerbations during follow-up, an improvement of QOL above the minimum clinically important difference (MCID) and an improvement in FEV1 of ≥100 mL from baseline. MEASUREMENTS AND MAIN RESULTS Cumulatively the three trials included 984 patients. Changes in FEV1, QOL and exacerbations were heterogeneous in all trials analysed. Improvements in QOL were not correlated to changes in FEV1 in the azithromycin and aztreonam trials (r=-0.17, p=0.1 and r=0.04, p=0.4) and weakly correlated in the mannitol trial (r=0.22, p<0.0001). An important placebo effect was observed in all trials, especially regarding improvements in QOL. Clinical meaningful lung function improvements were rare across all trials evaluated, suggesting that FEV1 is not a responsive measure in bronchiectasis. CONCLUSIONS Improvements in lung function, symptoms and exacerbation frequency are dissociated in bronchiectasis. FEV1 is poorly responsive and poorly correlated with other key outcome measures. Clinical parameters are poorly predictive of treatment response suggesting the need to develop biomarkers to identify responders.

Abstract
Background Persistent cough and large amounts of purulent sputum affects many bronchiectasis patients. No studies have evaluated the efficacy and safety of bronchoscopic airway clearance therapy and bronchoalveolar lavage (B-ACT) for non-cystic fibrosis bronchiectasis patients with acute exacerbation. Methods A randomised controlled trial was conducted to explore the efficacy and safety of B-ACT among 189 bronchiectasis inpatients from February 1, 2018 to February 28, 2019. The primary outcome was the time to first acute exacerbation. Secondary outcomes included changes of health-related scores, length of hospital stay, hospitalization expenses and incidences of adverse events. Findings B-ACT therapy significantly prolonged the median days to first acute exacerbation when compared with control group (198 vs 168 days, HR 0·555 (0·322-0·958), p=0·012; effect size(r)= 0·94). Further analysis showed that B-ACT therapy was more beneficial for these patients with severe disease and greater symptoms. COPD Assessment Test (CAT) scores improved significantly on the third day (5·45 vs 4·85, 0·60 (0·09-1·11), p=0·023), and Leicester Cough Questionnaire (LCQ) scores improved obviously on the third and seventh days (1·53 vs 1·23, 0·30 (0·05-0·55), p=0·044; 1·66 vs 1·32, 0·34 (0·08-0·60), p=0·022; respectively) after B-ACT therapy. Adverse events associated with B-ACT were mostly transient and mild. Differences of the lengths of hospital stay and hospitalization expenses in both group was not significant. Interpretation B-ACT therapy significantly prolonged the time to first acute exacerbation after discharge, highlighting the importance of B-ACT therapy focused on symptom improvements in preventing exacerbation.

Abstract
In this review paper, we discuss the characteristics that define severe bronchiectasis and which may lead to deterioration of noncystic fibrosis bronchiectasis. These characteristics were used to establish the current severity scores: bronchiectasis severity index (BSI), FACED, and E-FACED (exacerbation frequency, forced expiratory volume in 1 second, age, colonization, extension and dyspnea score). They can be used to predict mortality, exacerbation rate, hospital admission, and quality of life. Furthermore, there are different treatable traits that contribute to severe bronchiectasis and clinical deterioration. When present, they can be a target of the treatment to stabilize bronchiectasis.One of the first steps in treatment management of bronchiectasis is evaluation of compliance to already prescribed therapy. Several factors can contribute to treatment adherence, but to date no real interventions have been published to ameliorate this phenomenon. In the second step, treatment in deteriorating patients with bronchiectasis should be guided by the predominant symptoms, for example, cough, sputum, difficulty expectoration, exacerbation rate, or physical impairment. In the third step, we evaluate treatable traits that could influence disease severity in the deteriorating patient. Finally, in patients who are difficult to treat despite maximum medical treatment, eligibility for surgery (when disease is localized), should be considered. In case of end-stage disease, the evaluation for lung transplantation should be performed. Noninvasive ventilation can serve as a bridge to lung transplantation in patients with respiratory failure.

Abstract
INTRODUCTION Bronchiectasis is a growing global health problem. OBJECTIVE AND METHODS To evaluate the functional status of stable bronchiectasis patients recruited from a terciary hospital in Fortaleza, Brazil.The patients were submitted to spirometry, six minute walking test (6MWT), step test (6MST), measurement of fibrinogen,E-FACED scores(incorporates FEV1 ,age,colonisation by Pseudomonas,radiological extension, dyspnoea and exarcebation) and Duke Activity Status Index(DASI) test.Each item of DASI scored proportionally to the metabolic equivalentes(METs). The sum of DASI scores was applied for an estimation of oxygen consumption(VO2). RESULTS The sample comprised 101 patients.Patients with post-tuberculosis bronchiectsis had the lowest level of functional parameters than those with others etiologies[DASI(19.9 ±10.9 vs 31.2±14.4 p<0.001); VO2 (18.1 ± 4.7 vs 23.1 ± 6.1 p< 0.001 respectively)]. DASI scores and estimated VO2 correlated with E-FACED(r= -0.44 p=0.001; and r= -0.44 p=0.001 respectively) and 6MST r= 0.37 p<0.001 and r=0.40 p<0.001 respectively). CONCLUSION After multivariate analysis , bronchiectasis post-TB , E-FACED and 6MWT explained the impact on performance in bronchiectasis patients.

Abstract
Background Patients with bronchiectasis are at increased risk of developing non-tuberculous mycobacteria lung disease (NTM-LD), and published guidelines recommend regular testing for NTM infection in this patient population. Objective This study aimed to survey physicians managing patients with bronchiectasis to understand the perceived risk of NTM to their patients, perceived disease severity and frequency of testing for NTM. Methods The study comprised an online survey of hospital-based physicians in the UK, Germany, Italy, France and the Netherlands. The target group were hospital-based physicians who had managed at least 10 adult patients with bronchiectasis over the preceding 12 months. Results In total, 280 physicians completed the survey. Most (87%) thought their patients to be at particular risk of NTM, although it was perceived as a moderate risk versus other respiratory pathogens. Most perceived NTM-LD to impact patient morbidity (84%), and 61% indicated that NTM-LD significantly impacted mortality. 68% of all respondents did not test for NTM prior to initiating macrolide monotherapy, despite guidelines recommending testing. The perceived risk of and screening for NTM varied among countries. Conclusions The study demonstrates that physicians understand the risk of NTM-LD and associated morbidity in patients with bronchiectasis; however, a minority do not perceive that NTM-LD significantly affects mortality. Greater awareness of the need to test for NTM infection before initiating macrolide monotherapy for bronchiectasis is essential due to potential emergence of drug-resistant NTM.

Abstract
INTRODUCTION A number of multidimensional scoring systems, including the Bronchiectasis Severity Index (BSI), the FACED score, and the Exacerbation-FACED (Exa-FACED, a derivative of FACED), have been proposed and validated to assess the severity and prognosis in patients with bronchiectasis. Although these metrics have been validated through large multicenter efforts in Europe and Latin America, there have been no attempts at external validation in other populations. OJECTIVES The aim of this study was to validate specific multidimensional grading scales (BSI, FACED, and Exa-FACED) in predicting mortality, future exacerbations, and hospitalizations among Saudi patients with bronchiectasis. METHODS A prospective observational cohort study was conducted at a tertiary care centre. The three multidimensional grading scales (BSI, FACED, and Exa-FACED) were calculated for each patient. Future frequent acute exacerbations (≥2/year) and severe acute exacerbations leading to hospitalization were recorded for 1 year, and all-cause mortality was monitored for up to 5 years. RESULTS A total of 301 patients with bronchiectasis (mean age of 60±17 years and 66% female) were include. All Grading scales performed well in predicting 5-year survival. Area under the curve (AUC) values for BSI (0.86, 95% CI: 0.82-0.90), FACED (0.81, 95% CI: 0.76-0.85), and Ex-FACED (0.83, 95% CI: 0.78-0.87). The BSI (AUC=0.98, 95% CI: 0.96-0.99) performed better than FACED scoring (AUC=0.77, 95% CI: 0.71-0.81; P<0.0001) in predicting hospitalization. Exa-FACED scoring (AUC=0.84, 95% CI: 0.80-0.88) improved upon FACED scores in predicting hospitalization. The BSI (AUC=0.95, 95% CI: 0.91-0.97) fared significantly better than FACED scoring (AUC=0.76, 95% CI: 0.70-0.80; p<0.0001) in predicting frequent acute exacerbations (≥2/year). Again, Exa-FACED scoring (AUC=0.85, 95% CI: 0.81-0.89) improved upon FACED scores in predicting frequent acute exacerbations (≥2/year). CONCLUSIONS All scoring systems performed adequately in 5-year mortality projections. Although Exa-FACED scoring improved upon FACED scores in predicting forthcoming frequent acute exacerbations and hospitalization, the BSI outperformed both in this regard.

Abstract
We evaluated serum albumin as an index for predicting respiratory hospitalization in patients with bronchiectasis. We retrospectively reviewed the medical records of 177 patients with bronchiectasis, categorized them into low and normal albumin groups, and compared their clinical characteristics. The prediction of respiratory hospitalization by factors such as serum albumin level, bronchiectasis severity index (BSI), and FACED score (an acronym derived from five variables of forced expiratory volume in 1 s; FEV1, age, chronic colonization of Pseudomonas aeruginosa, extent of bronchiectasis, and dyspnea) was assessed. There were 15 and 162 patients categorized in the low and normal albumin groups, respectively. The low albumin group had lower body mass index and forced expiratory volume in 1 s, and higher age, frequency of previous respiratory hospitalization, percentage of Pseudomonas colonization, number of affected lobes, BSI and FACED scores, and C-reactive protein (CRP) level, than the normal albumin group. The areas under the receiver operating characteristic curve of serum albumin level and BSI and FACED scores for predicting respiratory hospitalization were 0.732 (95% confidence interval (CI), 0.647-0.816), 0.873 (95% CI, 0.817-0.928), and 0.708 (95% CI, 0.618-0.799), respectively. Albumin level, CRP, modified Medical Research Council score, and chronic Pseudomonas aeruginosa (and other organisms) colonization were independent risk factors for respiratory hospitalization. Low serum albumin level was associated with worse clinical condition, higher severity scores, and respiratory hospitalization in patients with bronchiectasis.

Abstract
Background/aim Two different scoring systems were developed to determine the severity of bronchiectasis: FACED scoring and the bronchiectasis severity index (BSI). In this study, we aim to compare these 2 scoring systems according to the 6-min walking distance test and a disease-specific health status questionnaire in patients with noncystic fibrosis bronchiectasis (NCFB). Materials and methods Smoking history, emergency and hospital admissions, and body mass index were obtained from NCFB patients admitted to our hospitals’ pulmonary rehabilitation unit between 2013 and 2018. Detailed pulmonary function tests were performed for all participants. Dyspnea perceptions were determined according to the mMRC dyspnea scale. The 6-min walking test was used to determine exercise capacity. The Saint George respiratory questionnaire (SGRQ) was applied to determine health status. Both FACED and BSI scores were calculated for all participants. Results There were a total of 183 participants, 153 of whom were men. A significant and strong correlation was found between FACED and BSI scores. As the severity of bronchiectasis increased, walking distance was significantly decreased and health status was significantly worse in both FACED and BSI scoring. A statistically significant but weak negative correlation was found between FACED score and walking distance. There was a significant negative correlation between BSI and walking distance, a stronger negative correlation than with FACED. Similarly, there was a significant negative correlation between health status and both FACED and BSI, but this correlation was stronger in the BSI score. Conclusion Although both FACED and BSI scores were negatively correlated with walking distance and health status in patients with NCFB, BSI was more strongly associated.

Abstract
Background: Bronchiectasis is a multidimensional lung disease characterized by bronchial dilation, chronic inflammation, and infection. The FACED (Forced expiratory volume in 1 s (FEV1), Age, Chronic colonization, Extension, and Dyspnea) score and Bronchiectasis Severity Index (BSI) are used to stratify disease risk and guide clinical practice. This meta-analysis aimed to quantify the accuracy of these two systems for predicting bronchiectasis outcomes. Methods: PubMed, Embase, and the Cochrane Database of Systematic Reviews were searched for relevant studies. Quality of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) criteria. Pooled summary estimates, including sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and diagnostic odds ratio (DOR) were calculated. Summary receiver operating characteristic curves were constructed, and the area under the curve (AUC) was used to evaluate prognostic performance. Results: We analyzed 17 unique cohorts (6525 participants) from ten studies. FACED scores with a cut-off value ≥ 5 predicted all-cause mortality better than BSI with a cut-off value ≥ 9, based on pooled sensitivity (0.34 vs 0.7), specificity (0.94 vs 0.66), PLR (4.76 vs 2.05), NLR (0.74 vs 0.48), DOR (6.67 vs 5.01), and AUC (0.87 vs 0.75). Both FACED scores with a cut-off value ≥ 5 (AUC = 0.82) and BSI scores with a cut-off value ≥ 5 or 9 (both AUC = 0.80) help to predict hospitalization. Conclusions: At a cut-off value ≥ 5, FACED scores can reliably predict all-cause mortality and hospitalization, while BSI scores can reliably predict hospitalization with a cut-off of ≥5 or ≥9. Further studies are essential to validate the prognostic performance of these two scores.

Abstract
Introduction Bronchiectasis is a chronic respiratory disease that can affect patients of all ages and significantly impact the quality of life (QOL) in patients who suffer from it. In spite of its widespread prevalence, and the significant impact on QOL, data on the quantitative impact of bronchiectasis on QOL is lacking. The Quality of Life-Bronchiectasis (QOL-B) is a self-administered patient-reported outcome measure, that was recently developed as a response to the emergent need for such measurement tools to study the impact of bronchiectasis on QOL. Methods We conducted a single-center cross-sectional study to study the correlation between QOL and various other outcome parameters such as exercise capacity, lung functions, co-morbidities, inflammatory markers, and body mass index (BMI). The secondary outcome was to find out various determinants of quality of life in non-cystic fibrosis bronchiectasis (NCFB). Results Forty-four patients who determined the pre-determined criteria for NCFB were enrolled in this study. This study demonstrated a significant impact on the QOL of NCFB patients based on the QOL-B scoring system. Almost all domains of QOL-B were found to be adversely impacted as measured by one or more of the outcome parameters but the FEV1, age, colonization, extension, dyspnea (FACED) score, bronchiectasis severity index (BSI) score, six-minute walk test (6MWD), and FEV1 showed associations across most scales while the other outcome parameters showed varying associations. Conclusions The QOL is significantly reduced in NCFB and it may be quantified using the QOL-B questionnaire. The impact on QOL in NCFB may be assessed using validated tools such as the FACED and BSI scoring systems, as well as other well-established outcome parameters like 6MWD and FEV1 predicted.

Abstract
Introduction: Comorbidities in patients with bronchiectasis are common and have a significant impact on clinical outcomes, contributing to lower quality of life, lung function, and exacerbation frequency. At least 13 comorbidities have been associated with a higher risk of mortality in bronchiectasis patients. Nonetheless, the kind of relationship between bronchiectasis and comorbidities is heterogeneous and poorly understood.Areas covered: different biological mechanisms leading to bronchiectasis could have a role in the development of the associated comorbidities. Some comorbidities could have a causal relationship with bronchiectasis, possibly through a variable degree of systemic inflammation, such as in rheumatic disorders and bowel inflammatory diseases. Other comorbidities, such as COPD or asthma, could be associated through airway inflammation and there is an uncertain cause-effect relationship. Finally, shared risk factors could link different comorbidities to bronchiectasis such as in the case of cardiovascular diseases, where the known link between chronic systemic inflammation and pulmonary infection could play a significant role.Expert opinion: Although different tools have been developed to assess the role of comorbidities in bronchiectasis , we believe that the implementation of current strategies to manage them is absolutely necessary and could significantly improve long-term prognosis in patients with bronchiectasis.

Abstract
BACKGROUND Bronchiectasis is predominantly a neutrophilic inflammatory disease. There are no established therapies that directly target neutrophilic inflammation because little is understood of the underlying mechanisms leading to severe disease. Neutrophil extracellular trap (NET) formation is a method of host defence that has been implicated in multiple inflammatory diseases. We aimed to investigate the role of NETs in disease severity and treatment response in bronchiectasis. METHODS In this observational study, we did a series of UK and international studies to investigate the role of NETs in disease severity and treatment response in bronchiectasis. First, we used liquid chromatography-tandem mass spectrometry to identify proteomic biomarkers associated with disease severity, defined using the bronchiectasis severity index, in patients with bronchiectasis (n=40) in Dundee, UK. Second, we validated these biomarkers in two cohorts of patients with bronchiectasis, the first comprising 175 patients from the TAYBRIDGE study in the UK and the second comprising 275 patients from the BRIDGE cohort study from centres in Italy, Spain, and UK, using an immunoassay to measure NETs. Third, we investigated whether pathogenic bacteria had a role in NET concentrations in patients with severe bronchiectasis. In a separate study, we enrolled patients with acute exacerbations of bronchiectasis (n=20) in Dundee, treated with intravenous antibiotics for 14 days and proteomics were used to identify proteins associated with treatment response. Findings from this cohort were validated in an independent cohort of patients who were admitted to the same hospital (n=20). Fourth, to assess the potential use of macrolides to reduce NETs in patients with bronchiectasis, we examined two studies of long-term macrolide treatment, one in patients with bronchiectasis (n=52 from the UK) in which patients were given 250 mg of azithromycin three times a week for a year, and a post-hoc analysis of the Australian AMAZES trial in patients with asthma (n=47) who were given 500 mg of azithromycin 3 times per week for a year. FINDINGS Sputum proteomics identified that NET-associated proteins were the most abundant and were the proteins most strongly associated with disease severity. This finding was validated in two observational cohorts, in which sputum NETs were associated with bronchiectasis severity index, quality of life, future risk of hospital admission, and mortality. In a subgroup of 20 patients with acute exacerbations, clinical response to intravenous antibiotic treatment was associated with successfully reducing NETs in sputum. Patients with Pseudomonas aeruginosa infection had a lessened proteomic and clinical response to intravenous antibiotic treatment compared with those without Pseudomonas infections, but responded to macrolide therapy. Treatment with low dose azithromycin was associated with a significant reduction in NETs in sputum over 12 months in both bronchiectasis and asthma. INTERPRETATION We identified NETs as a key marker of disease severity and treatment response in bronchiectasis. These data support the concept of targeting neutrophilic inflammation with existing and novel therapies.

Abstract
Background Currently, the prognosis of bronchiectasis is based on different prognostic indicators, like BSI and FACED score, founded on clinical-demographic, functional and radiological criteria. Both scoring systems include the number of lobes involved in bronchiectasis, which represents an adverse prognostic index. Our study aimed to investigate the prognostic role of the clinical-functional parameters and the number of involved lobes ratio in adult bronchiectasis. Methods The study was conducted on 52 patients diagnosed with non-cystic fibrosis bronchiectasis (NCFB) between 2015 and 2017 who attended the Pneumology Unit of Monaldi Hospital in Naples, Italy. Correlations between clinical- functional parameters (BMI, smoking history, number of exacerbations in the previous year, spirometry, DLCO, ABG test, and 6MWT) and number of involved lobes were investigated. Results At baseline, the number of exacerbations in the previous year had a statistically significant association with the number of involved lobes. Furthermore, at baseline, the radiological criterion was also negatively associated with some functional parameters (FEV1/FVC ratio e FEF25-75%). Statistical significance was lost during the follow up, demonstrating the effectiveness of the therapy. Conclusions Imaging extension represents a promising biomarker of disease severity as well as a helpful follow up tool for non-Cystic Fibrosis bronchiectasis (NCFB).

Abstract
Bronchiectasis, which is an abnormal and irreversible dilation of one or several bronchial segments, causes significant morbidity and impaired quality of life to patients, mainly as the result of recurrent and chronic respiratory infections. Staphylococcus aureus is a microorganism known for its high infectious potential related to the production of molecules with great pathogenic power, such as enzymes, toxins, adhesins, and biofilm, which determine the degree of severity of systemic symptoms and can induce exacerbated immune response. This review highlighted the clinical significance of S. aureus colonization/infection in bronchiectasis patients, since little is known about it, despite its increasing frequency of isolation and potential serious morbidity.

Abstract
BACKGROUND Similar to six-minute walk test (6MWT), sit-to-stand test (STST) is a self-paced test which elicits sub-maximal effort; therefore, it is suggested as an alternative measurement for functional exercise capacity in various pulmonary conditions including COPD and cystic fibrosis. We aimed to investigate the association between 30-second STST (30s-STST) and 6MWT in both children with bronchiectasis (BE) and their healthy counterparts, as well as exploring cardiorespiratory burden and discriminative properties of both tests. METHODS Sixty children (6 to 18-year-old) diagnosed with non-cystic fibrosis BE and 20 age-matched healthy controls were included. Both groups performed 30s-STST and 6MWT. Test results, and heart rate, SpO2 and dyspnea responses to tests were recorded. RESULTS Univariate analysis revealed that 30s-STST was able to explain 52% of variance in 6MWT (r = 0.718, p<0.001) in BE group, whereas 20% of variance in healthy controls (r = 0.453, p = 0.045). 6MWT elicited higher changes in heart rate and dyspnea level compared to 30s-STST, indicating it was more physically demanding. Both 30s-STST (21.65±5.28 vs 26.55±3.56 repetitions) and 6MWT (538±85 vs 596±54 m) were significantly lower in BE group compared to healthy controls (p<0.01). Receiver operating characteristic (ROC) curve analysis revealed an area under the ROC curve (UAC) of 0.765 for 30s-STST and 0.693 for 6MWT in identifying the individuals with or without BE (p<0.05). Comparison between AUCs of 30s-STST and 6MWT yielded no significant difference (p = 0.466), indicating both tests had similar discriminative properties. CONCLUSIONS 30s-STST is found to be a valid alternative measurement for functional exercise capacity in children with BE.

Abstract
Objective The aim of this study was to assess the clinical characteristics and outcomes of patients with post-tuberculosis (post-TB) bronchiectasis. We also evaluated the performance of various multidimensional severity score systems to predict mortality, future exacerbation, and hospitalization. Methods We conducted a prospective observational cohort study to evaluate the etiology of bronchiectasis in 301 patients. Patients fell into three groups: post-TB (129 [43%]), idiopathic (76 [25%]), and other (96 [32%]) etiologies of bronchiectasis. Four multidimensional grading scales, including the Bronchiectasis Severity Index (BSI), the FACED score, and two derivative versions of the FACED score, Exacerbation (Exa-FACED and E-FACED), were calculated and compared for each patient. Results Patients with post-TB bronchiectasis were predominantly female (61%) with a mean age of 68±11 years. Moreover, 26% of post-TB bronchiectasis patients were colonized with Pseudomonas aeruginosa. At baseline, patients with post-TB bronchiectasis were older, had higher severity scores, and were more likely to have experienced severe exacerbations that required hospitalization compared to patients with idiopathic bronchiectasis or bronchiectasis arising from other causes. During follow-up, 52% of patients required hospitalization, 58% had frequent (≥2 per year) acute exacerbations, and the overall 5-year mortality rate was 30%. Five-year survival was efficiently predicted by each of the grading scales. Although the modified variations of the FACED outperformed the original FACED scale in predicting forthcoming frequent acute exacerbations and hospitalization, the BSI outperformed all three systems in this regard. Conclusion Patients with post-TB bronchiectasis had higher severity scores than patients with idiopathic bronchiectasis or bronchiectasis arising from other causes. In addition, all scoring systems performed adequately in 5-year mortality projections. BSI and the modified versions of the FACED outperformed the FACED in predicting forthcoming exacerbations and hospitalizations.

Abstract
PURPOSE Coronary artery calcification (CAC) on thoracic computed tomography (CT) can identify patients at risk of coronary artery disease (CAD) mortality. However, the overlap between bronchiectasis and CAC severity for predicting subsequent outcomes is unknown. MATERIALS AND METHODS CT images from 362 patients (mean age 66±14 y, 38% male) with known bronchiectasis were assessed. Bronchiectasis severity was assessed using the Bronchiectasis Severity Index (0 to 4, mild; 5 to 8, moderate; and ≥9, severe). CAC was assessed with a visual ordinal score (0, none; 1, mild; 2, moderate; 3, severe) in each of the left main stem, left anterior descending, left circumflex, and right coronary arteries. Vessel CAC scores were summed and categorized as none (0), mild (1 to 3), moderate (4 to 8), and severe (9 to 12). RESULTS Patients with severe bronchiectasis were older (P<0.001), but were not more likely to have a history of CAD, hypertension, or smoking. CAC was present in 196 (54%). Over a mean of 6±2 years, 59 (16%) patients died. Patients with moderate or severe CAC were 5 times more likely to die than patients without CAC (hazard ratio: 5.49, 95% confidence interval: 2.82-10.70, P<0.001). Patients with severe bronchiectasis were 10 times more likely to die than patients with mild bronchiectasis (hazard ratio: 10.11, 95% confidence interval: 4.22-24.27, P<0.001). CAC and bronchiectasis severity were independent predictors of mortality, but age, sex, smoking, and history of CAD or cerebrovascular disease were not. CONCLUSIONS CAC is common in patients with bronchiectasis, and both CAC and bronchiectasis severity are independent predictors of mortality.

Abstract
INTRODUCTION Inhaled antibiotics may improve symptom scores, but it is not known which specific symptoms improve with therapy. Item-level analysis of questionnaire data may allow us to identify which specific symptoms respond best to treatment. METHODS Post hoc analysis of the AIR-BX1 studies and two trials of inhaled aztreonam versus placebo in bronchiectasis. Individual items from the quality of life bronchiectasis (QOL-B) respiratory symptom scale, were extracted as representing severity of nine distinct symptoms. Generalised linear models were used to evaluate changes in symptoms with treatment versus placebo from baseline to end of first on-treatment cycle and mixed models were used to evaluate changes across the full 16-week trial. RESULTS Aztreonam improved cough (difference 0.22, 95% CI 0.08-0.37; p=0.002), sputum production (0.30, 95% CI 0.15-0.44; p<0.0001) and sputum colour (0.29, 95% CI 0.15-0.43; p<0.0001) versus placebo equating to a 20% improvement in cough and 25% improvement in sputum production and colour. Similar results were observed for cough, sputum production and sputum purulence across the trial duration (all p<0.05). Patients with higher sputum production and sputum colour scores had a greater response on the overall QOL-B (difference 4.82, 95% CI 1.12-8.53; p=0.011 for sputum production and 5.02, 95% CI 1.19-8.86; p=0.01 for sputum colour). In contrast, treating patients who had lower levels of bronchitic symptoms resulted in shorter time to next exacerbation (hazard ratio 1.83, 95% CI 1.02-3.28; p=0.042). CONCLUSION Baseline bronchitic symptoms predict response to inhaled aztreonam in bronchiectasis. More sensitive tools to measure bronchitic symptoms may be useful to better identify inhaled antibiotic responders and to evaluate patient response to treatment.

Abstract
OBJECTIVE To characterize a population of patients with bronchiectasis, correlating clinical, radiological, and functional aspects with the severity of dyspnea. METHODS This was a cross-sectional study involving adult patients with HRCT-confirmed bronchiectasis, categorized according to the severity of dyspnea (as being mildly or severely symptomatic, on the basis of the modified Medical Research Council scale). We correlated the severity of dyspnea with clinical parameters, functional parameters (spirometry values, lung volumes, and DLCO), and CT parameters. RESULTS We evaluated 114 patients, 47 (41%) of whom were men. The median age (interquartile range) was 42 years (30-55 years). The most common form was idiopathic bronchiectasis. Of the 114 patients, 20 (17.5%) were colonized with Pseudomonas aeruginosa and 59 (51.8%) were under continuous treatment with macrolides. When we applied the Exacerbation in the previous year, FEV1, Age, Colonization, Extension, and Dyspnea score, the severity of dyspnea was categorized as moderate in 54 patients (47.4%), whereas it was categorized as mild in 50 (43.9%) when we applied the Bronchiectasis Severity Index. The most common lung function pattern was one of obstruction, seen in 95 patients (83.3%), and air trapping was seen in 77 patients (68.7%). The prevalence of an obstructive pattern on spirometry was higher among the patients with dyspnea that was more severe, and most functional parameters showed reasonable accuracy in discriminating between levels of dyspnea severity. CONCLUSIONS Patients with bronchiectasis and dyspnea that was more severe had greater functional impairment. The measurement of lung volumes complemented the spirometry data. Because bronchiectasis is a complex, heterogeneous condition, a single variable does not seem to be sufficient to provide an overall characterization of the clinical condition.

Abstract
BACKGROUND Bronchiectasis is a common but neglected chronic lung disease. Most epidemiological data are limited to cohorts from Europe and the USA, with few data from low-income and middle-income countries. We therefore aimed to describe the characteristics, severity of disease, microbiology, and treatment of patients with bronchiectasis in India. METHODS The Indian bronchiectasis registry is a multicentre, prospective, observational cohort study. Adult patients (≥18 years) with CT-confirmed bronchiectasis were enrolled from 31 centres across India. Patients with bronchiectasis due to cystic fibrosis or traction bronchiectasis associated with another respiratory disorder were excluded. Data were collected at baseline (recruitment) with follow-up visits taking place once per year. Comprehensive clinical data were collected through the European Multicentre Bronchiectasis Audit and Research Collaboration registry platform. Underlying aetiology of bronchiectasis, as well as treatment and risk factors for bronchiectasis were analysed in the Indian bronchiectasis registry. Comparisons of demographics were made with published European and US registries, and quality of care was benchmarked against the 2017 European Respiratory Society guidelines. FINDINGS From June 1, 2015, to Sept 1, 2017, 2195 patients were enrolled. Marked differences were observed between India, Europe, and the USA. Patients in India were younger (median age 56 years [IQR 41-66] vs the European and US registries; p<0·0001]) and more likely to be men (1249 [56·9%] of 2195). Previous tuberculosis (780 [35·5%] of 2195) was the most frequent underlying cause of bronchiectasis and Pseudomonas aeruginosa was the most common organism in sputum culture (301 [13·7%]) in India. Risk factors for exacerbations included being of the male sex (adjusted incidence rate ratio 1·17, 95% CI 1·03-1·32; p=0·015), P aeruginosa infection (1·29, 1·10-1·50; p=0·001), a history of pulmonary tuberculosis (1·20, 1·07-1·34; p=0·002), modified Medical Research Council Dyspnoea score (1·32, 1·25-1·39; p<0·0001), daily sputum production (1·16, 1·03-1·30; p=0·013), and radiological severity of disease (1·03, 1·01-1·04; p<0·0001). Low adherence to guideline-recommended care was observed; only 388 patients were tested for allergic bronchopulmonary aspergillosis and 82 patients had been tested for immunoglobulins. INTERPRETATION Patients with bronchiectasis in India have more severe disease and have distinct characteristics from those reported in other countries. This study provides a benchmark to improve quality of care for patients with bronchiectasis in India.

Abstract
Non-cystic fibrosis (non-CF) bronchiectasis is a chronic pulmonary disease that can lead to malnutrition. Serum prealbumin and albumin level are related to inflammatory and nutritional status. Thus, we aimed to confirm our hypothesis that low serum albumin and prealbumin level, as well as body mass index (BMI), is correlated to severe non-CF bronchiectasis. We conducted a retrospective cross-sectional study of 128 patients, including 75 patients with prealbumin test and 79 patients with albumin test. Detailed medical history was recorded, including pulmonary function tests and high-resolution computed tomography. bronchiectasis severity index (BSI) and FACED scores were calculated. Leicester Cough Questionnaire, Quality of Life Questionnaire-Bronchiectasis, chronic obstructive pulmonary disease (COPD) assessment test and Patient Health Questionnaire-9 questionnaires were used to assess patients' clinical symptoms. Correlation analysis showed that BSI score was more correlated to patients' clinical symptoms than FACED. Thus, patients were divided into three groups of different severity based on BSI score. Albumin, prealbumin and BMI showed a significant difference between three groups. Correlation and multivariable linear regression analysis showed that serum albumin and prealbumin level were correlated to BSI, FACED and questionnaires. The analysis between three indices and PFT/high-resolution computed tomography (HRCT) showed that prealbumin, albumin and BMI could reflect the PFT and modified Reiff score in non-CF bronchiectasis. In conclusion, BMI, albumin and prealbumin showed a significant correlation with the BSI, FACED, as well as patients' clinical symptoms. Among them, serum albumin was the indicator most strongly associated with the BSI and questionnaires, while prealbumin could better reflect lung function decline and radiological severity.

Abstract
Plasma drug concentrations, spectrum of antibacterial activity and minimum inhibitory concentration (MIC) had been widely considered as markers of the efficacy of antibiotics. Nonetheless, in several cases, antibiotics characterized by all these features were ineffective for the treatment of respiratory tract infections. A typical paradigm represented the case of patients with bronchiectasis who do not always benefit from antibiotics and thus experiencing increased sputum production, worse quality of life, more rapid forced expiratory volume in the first second (FEV1) decline, more frequent exacerbations and increased mortality rates, especially those with Pseudomonas aeruginosa (P. aeruginosa) chronic infection. Subsequently, penetrance of antibiotics in the epithelial lining fluid has gradually emerged as another key factor for the outcome of antibiotic treatment. Given that a plethora of antibiotics presented with poor or intermediate penetrance in the epithelial lining fluid, inhaled antibiotics targeting directly the site of infection emerged as a new option for patients with respiratory disorders including patients with bronchiectasis. This review article intends to summarize the current state of knowledge for the penetrance of antibiotics in the epithelial lining fluid and present results from clinical trials of inhaled antibiotics in patients with bronchiectasis of etiology other than cystic fibrosis.

Abstract
BACKGROUND Objective assessment of symptoms in bronchiectasis is important for research and in clinical practice. The COPD Assessment Test (CAT) is a short, simple assessment tool widely used in COPD. The items included in the CAT are not specific to COPD and also reflect the dominant symptoms of bronchiectasis. We therefore performed a study to validate the CAT as an outcome measure in bronchiectasis. METHODS The CAT was administered to two cohorts of bronchiectasis patients along with other quality of life questionnaires. Patients underwent comprehensive clinical assessment. One cohort had repeated questionnaires collected before-and-after treatment of acute exacerbations. We analyzed convergent validity, repeatability, and responsiveness of the score and calculated the minimum clinically important difference (MCID) using a combination of distribution and anchor-based methods. RESULTS In both cohorts there were positive correlations between the CAT and the St. George's Respiratory Questionnaire (r = 0.90, P < .0001 and r = 0.87, P < .0001). There was an inverse relationship between CAT and Quality of Life - Bronchiectasis Respiratory Symptoms Scale (r = -0.75, P < .0001) and Leicester Cough Questionnaire score (r = -0.77, P < .0001). Patients with more severe disease, based on the bronchiectasis severity index, had significantly higher CAT scores. CAT also correlated with FEV1 % predicted and 6-min walk distance (6MWD). CAT increased significantly at exacerbation and fell at recovery. The intraclass correlation coefficient for two measurements four-weeks apart while clinically stable was 0.88 (95% CI, 0.73-0.95, P < .0001). An MCID of 4 was most consistent. CONCLUSIONS CAT is a valid, responsive symptom assessment tool in bronchiectasis. The MCID is estimated as 4 points.
