Abstract
Bronchiectasis, particularly in children, is an increasingly recognised yet neglected chronic lung disorder affecting individuals in both low-to-middle and high-income countries. It has a high disease burden and there is substantial inequity within and between settings. Furthermore, compared with other chronic lung diseases, considerably fewer resources are available for children with bronchiectasis. The need to prevent bronchiectasis and to reduce its burden also synchronously aligns with its high prevalence and economic costs to health services and society. Like many chronic lung diseases, bronchiectasis often originates early in childhood, highlighting the importance of reducing the disease burden in children. Concerted efforts are therefore needed to improve disease detection, clinical management and equity of care. Modifiable factors in the causal pathways of bronchiectasis, such as preventing severe and recurrent lower respiratory infections should be addressed, whilst also acknowledging the role played by social determinants of health. Here, we highlight the importance of early recognition/detection and optimal management of bronchiectasis in children, and outline our research, which is attempting to address important clinical knowledge gaps discussed in a recent workshop. The research is grouped under three themes focussing upon primary prevention, improving diagnosis and disease characterisation, and providing better management. Our hope is that others in multiple settings will undertake additional studies in this neglected field to further improve the lives of people with bronchiectasis. We also provide a resource list with links to help inform consumers and healthcare professionals about bronchiectasis and its recognition and management.

Abstract
Bronchiectasis is a clinical-radiological condition composed of irreversible bronchial dilation due to inflammation and infection of the airways, which causes respiratory symptoms, usually productive cough and infectious exacerbations. Bronchiectasis can have multiple causes, both pulmonary and extrapulmonary, and its clinical presentation is very heterogenous. Its prevalence is unknown, although up to 35-50% of severe COPD and 25% of severe asthma present them, so their underdiagnosis is evident. Chronic bacterial bronchial infection is common, and Pseudomonas aeruginosa is the pathogen that has been found to imply a worse prognosis. Treatment of bronchiectasis has three fundamental characteristics: it must be multidisciplinary (involvement of several specialties), pyramidal (from primary care to the most specialized units) and multidimensional (management of all aspects that make up the disease).

Abstract
Background The denomination of noncystic fibrosis bronchiectasis (NCFB) includes several causes, and differences may be expected between the patient subgroups regarding age, comorbidities, and clinical and functional evolution. This study sought to identify the main causes of NCFB in a cohort of stable adult patients and to investigate whether such conditions would be different in their clinical, functional, and quality of life aspects. Methods Between 2017 and 2019, all active patients with NCFB were prospectively evaluated searching for clinical data, past medical history, dyspnea severity grading, quality of life data, microbiological profile, and lung function (spirometry and six-minute walk test). Results There was a female predominance; mean age was 54.7 years. Causes were identified in 82% of the patients, the most frequent being postinfections (n = 39), ciliary dyskinesia (CD) (n = 32), and chronic obstructive pulmonary disease (COPD) (n = 29). COPD patients were older, more often smokers (or former smokers) and with more comorbidities; they also had worse lung function (spirometry and oxygenation) and showed worse performance in the six-minute walk test (6MWT) (walked distance and exercise-induced hypoxemia). Considering the degree of dyspnea, in the more symptomatic group, patients had higher scores in the three domains and total score in SGRQ, besides having more exacerbations and more patients in home oxygen therapy. Conclusions Causes most identified were postinfections, CD, and COPD. Patients with COPD are older and have worse pulmonary function and more comorbidities. The most symptomatic patients are clinically and functionally more severe, besides having worse quality of life.

Abstract
The term "destroyed lung" signifies the complete degradation of lung tissues, typically due to chronic or recurring lung infections, with tuberculosis often identified as a primary culprit. This condition, when occurs after tuberculosis and is known as post-tubercular destroyed lung syndrome, poses considerable difficulties, especially in areas where tuberculosis is prevalent. This paper outlines a case study involving a 50-year-old Indian man afflicted with destroyed lung syndrome. Despite having undergone tuberculosis treatment three years earlier, the patient exhibited symptoms such as a dry cough, coughing up blood, and difficulty breathing. A comprehensive clinical evaluation and radiological assessments confirmed the diagnosis of destroyed lung syndrome, leading to the commencement of appropriate treatment.

Abstract
Post-tuberculosis lung disease (PTLD) has only recently been put in the spotlight as a medical entity. Recent data suggest that up to 50% of tuberculosis (TB) patients are left with PTLD-related impairment after completion of TB treatment. The presence of residual cavities in the lung is the largest risk factor for the development of chronic pulmonary aspergillosis (CPA) globally. Diagnosis of CPA is based on four criteria including a typical radiological pattern, evidence of Aspergillus species, exclusion of alternative diagnosis, and a chronic course of disease. In this manuscript, we provide a narrative review on CPA as a serious complication for patients with PTLD.

Abstract
Chronic Pseudomonas aeruginosa (PA) infection significantly contributes to morbidity and mortality in bronchiectasis patients. Initiating antibiotics early may lead to the eradication of PA. Here we outline the design of a trial (ERASE; NCT06093191) assessing the efficacy and safety of inhaled tobramycin, alone or with oral ciprofloxacin, in bronchiectasis patients with a new isolation of PA. This multicentre, 2×2 factorial randomised, double-blind, placebo-controlled, parallel-group trial includes a 2-week screening period, a 12-week treatment phase (with a combination of ciprofloxacin or a placebo at initial 2 weeks) and a 24-week follow-up. 364 adults with bronchiectasis and a new PA isolation will be randomly assigned to one of four groups: placebo (inhaled saline and ciprofloxacin placebo twice daily), ciprofloxacin alone (750 mg ciprofloxacin and inhaled saline twice daily), inhaled tobramycin alone (inhaled 300 mg tobramycin and ciprofloxacin placebo twice daily) or a combination of both drugs (inhaled 300 mg tobramycin and 750 mg ciprofloxacin twice daily). The primary objective of this study is to assess the proportion of patients successfully eradicating PA in each group by the end of the study. Efficacy will be evaluated based on the eradication rate of PA at other time points (12, 24 and 36 weeks), the occurrence of exacerbations and hospitalisations, time to first pulmonary exacerbations, patient-reported outcomes, symptom measures, pulmonary function tests and the cost of hospitalisations. To date no randomised trial has evaluated the benefit of different PA eradication strategies in bronchiectasis patients. The ERASE trial will therefore generate crucial data to inform future clinical guidelines.

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 Bronchiectasis, once rarely encountered, appears to be increasing in prevalence in South Africa (SA) and globally. There is a lack of published data on non-cystic fibrosis (CF) bronchiectasis, specifically in low- to middle-income countries, despite the high rates of risk factors such as HIV, pulmonary tuberculosis, and other infections. Objectives Given this lack of data, to review the characteristics of adult patients with non-CF bronchiectasis at a tertiary academic hospital in Johannesburg, SA. Methods This was a single-centre, retrospective record review, including all cases of non-CF bronchiectasis that were in the records of the adult pulmonology clinic at Charlotte Maxeke Johannesburg Academic Hospital as of April 2017. Results There were 197 patients, with a slight predominance of males, and the patients were generally young. The HIV rate was higher than the national average (34.8% v. 13.7%), and the HIV-positive patients had a high TB prevalence (86.9%). Pseudomonas spp. were cultured from sputum in 15.3% of cases. Fewer than half of the cohort had the diagnosis of bronchiectasis confirmed by high-resolution chest tomography. Airway obstruction (forced expiratory volume in 1 second/forced vital capacity ratio <70%) was observed in 47.0% of patients. Treatment with a short-acting beta-2-agonist was prescribed in 62.9%, a long-acting beta-2-agonist in 43.6% and inhaled corticosteroids in 51.3%. Antibiotic therapy during exacerbations was used in 44.2%, mainly amoxycillin-clavulanate (66.7%). Conclusion While single centre and retrospective, this study adds to the data on non-CF bronchiectasis in sub-Saharan Africa and should encourage further research to increase our understanding of adult non-CF bronchiectasis in SA. Study synopsis What the study adds. This study adds to published data detailing the clinical characteristics of adult non-cystic fibrosis (CF) bronchiectasis in low- and middle-income countries (LMICs).Implications of the findings. As a retrospective descriptive study, the findings summarise the characteristics of adults with non-CF bronchiectasis in a cohort from Johannesburg, South Africa. The findings suggest that the characteristics of bronchiectasis in this region appear to be similar in several ways to those in other LMICs, but quite different from those in the developed world.

Abstract
Bronchiectasis is the third leading chronic inflammatory disease of the airway caused by dozens of pulmonary and extra-pulmonary diseases. Infection by pathogenic microorganisms is very common. We aimed to analyze, for the first time in the literature, the etiology of bronchiectasis throughout the world via data published in national and international registries. A bibliographic search was carried out in PubMed and Web of Science. Seven studies were included, with a total of 27,258 patients from 33 countries of four continents. The most frequent cause of bronchiectasis was post-infectious: 30.5% (range: 19.1-40.4%), followed by idiopathic: 28.7% (18.5-38.1%). Post-tuberculous bronchiectasis accounted for 14.1% (1.8-35.5%), while etiologies associated with COPD and asthma comprised 7% (3.4-10.9%) and 5.2% (2.5-7.8%). In conclusion, there was a high degree of heterogeneity in the relative percentages of the main causes of bronchiectasis in the world, although post-infectious and idiophatic bronchiectasis continue to be the most frequent causes.

Abstract
Background Bronchiectasis is a chronic lung disorder that affects the lives of many South Africans. Post-tuberculosis (TB) bronchiectasis is an important complication of previous pulmonary TB and a common cause of bronchiectasis in South Africa (SA). No previous statements on the management of bronchiectasis in SA have been published. Objectives To provide a position statement that will act as a template for the management of adult patients with bronchiectasis in SA. Methods The South African Thoracic Society appointed an editorial committee to compile a position statement on the management of adult non-cystic fibrosis (CF) bronchiectasis in SA. Results A position statement addressing the management of non-CF bronchiectasis in adults in SA was compiled. This position statement covers the epidemiology, aetiology, diagnosis, investigations and various aspects of management of adult patients with non-CF bronchiectasis in SA. Conclusion Bronchiectasis has largely been a neglected lung condition, but new research has improved the outlook for patients. Collaboration between interprofessional team members in patient management is important. In SA, more research into the epidemiology of bronchiectasis, especially post-TB bronchiectasis and HIV-associated bronchiectasis, is required. Abstract The South African Thoracic Society mandated a multidisciplinary team of healthcare providers to compile a position statement on the management of non-cystic fibrosis bronchiectasis in South Africa (SA). International guidelines on the management of bronchiectasis were reviewed and used as a basis from which the current position statement was compiled. This is the first position statement on the management of adult non-cystic fibrosis bronchiectasis in SA. A description of the epidemiology and aetiology of bronchiectasis is provided, as well as guidance on its diagnosis and management. The position statement provides guidance on the management of bronchiectasis to healthcare providers, policymakers and regulatory authorities.

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.

Residual respiratory disability after successful treatment of pulmonary tuberculosis: a systematic review and meta-analysis. EClinicalMedicine 2023; 59:101979. [PMID: 37205923 PMCID: PMC10189364 DOI: 10.1016/j.eclinm.2023.101979] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 04/05/2023] [Accepted: 04/12/2023] [Indexed: 05/21/2023] Open
Abstract
Background Pulmonary tuberculosis (PTB) can result in long-term health consequences, even after successful treatment. We conducted a systematic review and meta-analysis to estimate the occurrence of respiratory impairment, other disability states, and respiratory complications following successful PTB treatment. Methods We identified studies from January 1, 1960, to December 6, 2022, describing populations of all ages that successfully completed treatment for active PTB and had been assessed for at least one of the following outcomes: occurrence of respiratory impairment, other disability states, or respiratory complications following PTB treatment. Studies were excluded if they reported on participants with self-reported TB, extra-pulmonary TB, inactive TB, latent TB, or if participants had been selected on the basis of having more advanced disease. Study characteristics and outcome-related data were abstracted. Meta-analysis was performed using a random effects model. We adapted the Newcastle Ottawa Scale to evaluate the methodological quality of the included studies. Heterogeneity was assessed using the I2 statistic and prediction intervals. Publication bias was assessed using Doi plots and LFK indices. This study is registered with PROSPERO (CRD42021276327). Findings 61 studies with 41,014 participants with PTB were included. In 42 studies reporting post-treatment lung function measurements, 59.1% (I2 = 98.3%) of participants with PTB had abnormal spirometry compared to 5.4% (I2 = 97.4%) of controls. Specifically, 17.8% (I2 = 96.6%) had obstruction, 21.3% (I2 = 95.4%) restriction, and 12.7% (I2 = 93.2%) a mixed pattern. Among 13 studies with 3179 participants with PTB, 72.6% (I2 = 92.8%) of participants with PTB had a Medical Research Council dyspnoea score of 1-2 and 24.7% (I2 = 92.2%) a score of 3-5. Mean 6-min walk distance in 13 studies was 440.5 m (I2 = 99.0%) in all participants (78.9% predicted, I2 = 98.9%) and 403.0 m (I2 = 95.1%) among MDR-TB participants in 3 studies (70.5% predicted, I2 = 97.6%). Four studies reported data on incidence of lung cancer, with an incidence rate ratio of 4.0 (95% CI 2.1-7.6) and incidence rate difference of 2.7 per 1000 person-years (95% CI 1.2-4.2) when compared to controls. Quality assessment indicated overall low-quality evidence in this field, heterogeneity was high for pooled estimates of nearly all outcomes of interest, and publication bias was considered likely for almost all outcomes. Interpretation The occurrence of post-PTB respiratory impairment, other disability states, and respiratory complications is high, adding to the potential benefits of disease prevention, and highlighting the need for optimised management after successful treatment.

Abstract
A destroyed lung pertains to the complete destruction of the lung. This is an irreversible condition and is an outcome of chronic or recurrent lung infections. Tuberculosis is widely reported to be a cause of destroyed lungs, and post-tubercular destroyed lung syndrome is a major issue, especially in countries with a high burden of tuberculosis. Herein, a case of destroyed lung syndrome in a 22-year-old Indian male is presented. He had a history of irregular treatment for tuberculosis and reported complaints of dry cough, fever, and dyspnea. A detailed clinical, radiological, and lab workup established the diagnosis of destroyed lung syndrome, and he was reinitiated on anti-tubercular treatment.

Abstract
Abstract
Background
Bronchiectasis is a chronic pulmonary disease characterized by widened, malformed bronchi, with profuse expectoration and impaired quality of life. COPD and ILD are common co-morbidities with bronchiectasis.
Methods
The present study evaluated the clinical, laboratory& radiological characteristics of COPD and ILD with/without bronchiectasis. A hospital-based, retrospective study was conducted for 1 year.
Results
A total of 101 patients were analyzed, 60 patients had COPD, 34 had ILD and 7 patients had bronchiectasis without COPD or ILD. It was noticed that, out of the analyzed 60 COPD patients, 10 patients developed bronchiectasis (16.7%) versus10 patients of 34 ILD patients (29.4%). In COPD and ILD accompanied by bronchiectasis, the incidence of hemoptysis was significantly higher in comparison to those without bronchiectasis. Moreover, they showed a significant increase in partial pressure of carbon dioxide (PCO2) in comparison to those without bronchiectasis, as well as in comparison to bronchiectasis only. Sputum culture revealed that COPD with bronchiectasis were significantly associated with Staphlococcus aureus (77.8%), more than ILD with Bronchiectasis (33.3%). While S. pneumoniae were more evident in cases of ILD with bronchiectasis (22.2%). The bilateral, peripheral bronchiectasis was more common than the unilateral, central bronchiectasis among cases of COPD with bronchiectasis followed by ILD with bronchiectasis more than bronchiectasis only.
Conclusion
Patients with COPD /ILD with bronchiectasis can be associated with serious clinical manifestations as hemoptysis. Their sputum cultures detected more positive organisms than negative in comparison to cases of bronchiectasis only. Screening of COPD and ILD patients using HRCT Scanning is a recommended preventive measure for early detection of bronchiectasis.

Airway clearance treatments in bronchiectasis: feasibility of linking survey results to registry data and a survey of patients' and physiotherapists' practices. ERJ Open Res 2023; 9:00540-2022. [PMID: 36949967 PMCID: PMC10026005 DOI: 10.1183/23120541.00540-2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Accepted: 11/21/2022] [Indexed: 12/24/2022] Open
Abstract
Background and objective There are limited data on airway clearance treatment (ACT) practices. This study aimed to: 1) assess the feasibility of collecting online surveys on ACTs from patients and physiotherapists and linking the patient survey data to outcome data in the Bronch-UK/EMBARC Registry; 2) assess the association between ACT practices and outcome data; and 3) ascertain the factors affecting physiotherapist ACT practices. Methods Survey methodology was used to collect data from patients with bronchiectasis and physiotherapists in Northern Ireland. Associations between patient survey data and linked Bronch-UK/EMBARC Registry patient outcome data were explored. Results It was feasible to conduct an online survey with patients with bronchiectasis and link the data to the Bronch-UK/EMBARC Registry. 13% of patients did not perform ACTs. ACTs were used more often by patients who were symptomatic/had more severe disease compared to those with milder symptoms/disease. Patients used ACTs when they were symptomatic rather than as a preventative management strategy. Physiotherapists generally followed the bronchiectasis guidelines, using the stepwise approach to management. Conclusion Our survey provided information about the feasibility of linking online survey and patient registry data. This study provides up-to-date information on ACT practice throughout the course of the disease trajectory as well as insight into the implementation of bronchiectasis guidelines by physiotherapists. Future work should explore how to optimise ACT data collection to maximise the use of real-world ACT data in bronchiectasis research and inform priority ACT research questions.

Abstract
Bronchiectasis is a complex and heterogeneous disease. Its pathophysiology is poorly understood, but chronic bronchial infection plays an important role in its natural history, and is associated with poor quality of life, more exacerbations and increased mortality. Pseudomonas aeruginosa, Haemophilus influenzae and Staphylococcus aureus are the most common bacteria related to chronic bronchial infection. Non-tuberculous mycobacteria, fungi and respiratory viruses are also present during clinical stability, and may increase the risk of acute exacerbation. Chronic inflammation is present in bronchiectasis, especially neutrophilic inflammation. However, macrophages and eosinophils also play a key role in the disease. Finally, airway epithelium has innate mechanisms such as mucociliary clearance and antibacterial molecules like mucins and antimicrobial peptides that protect the airways from pathogens. This review addresses how the persistence of microorganisms in the airways and the imbalance of the immune system contribute to the development of chronic bronchial infection in bronchiectasis.

Abstract
Introduction Among chronic respiratory diseases, bronchiectasis is one of the important causes of mortality and morbidity in developing countries. Objective This study aimed to assess the clinical, radiological, microbiological, and pulmonary function profiles of adult patients with post-tubercular bronchiectasis. Methods We enrolled 138 patients with bronchiectasis confirmed by high-resolution CT scans from July 2017 to August 2018. Results A total of 138 patients with bronchiectasis were enrolled. The data from 132 patients were analyzed; six patients were excluded from the study. The mean age of post-TB bronchiectasis (post-tuberculosis bronchiectasis) patients was 36.08±13.08, which was lower than the non-tuberculosis bronchiectasis group. The proportion of the male population was more in the post-TB bronchiectasis group (54.55% vs. 37.88%, p=0.48). Smoking prevalence was high in post-TB bronchiectasis (27.27% vs. 12.12%, p=0.04). The predominant symptom was cough in the post-tubercular bronchiectasis group (48.5% vs. 41.7%, p=0.019). The history of the recurrent common cold was seen most frequently in non-post-tubercular bronchiectasis (40.9% vs. 12.9%, p=0.001). The most common radiological variant of bronchiectasis found in all patients was a cystic type (75%). The most common site of involvement was the left lower lobe, followed by the lingula in all patients and post-tuberculosis bronchiectasis patients. Pulmonary function on spirometry revealed obstructive, restrictive, and mixed patterns in 55%, 25%, and 15%, respectively. Patients with post-tuberculosis bronchiectasis had lower lung function post-FEV1/FVC (forced expiratory volume in one second/forced vital capacity) ratio (70.31±15.56 vs. 76.85±11.82, p=0.015). Binary multivariate logistic regression analysis showed that only recurrent cough cold was a significant independent risk factor for post-TB bronchiectasis. Conclusion Post-tuberculosis, and bronchiectasis followed by post-infectious causes, were the most common causes of bronchiectasis and poor lung function.

Abstract
BACKGROUND Physiotherapy-led airway clearance interventions are indicated for some people with chronic lung conditions. This study describes Australian clinical models for the provision of adult airway clearance services. METHODS This cross-sectional national study recruited public and private health care providers (excluding cystic fibrosis-specific services) identified by a review of websites. Providers were invited to complete an electronic 61-item survey with questions about airway clearance service context, referral demographics, service provision and program metrics. Data were reported descriptively with differences between metropolitan and non-metropolitan services explored with chi-square tests. RESULTS Between October-December 2019, the survey was disseminated to 131 providers with 91 responses received (69% response rate; 87 (96%) public (34 metropolitan; 53 non-metropolitan) and 4 (4%) private). Intent (chronic condition self-management) and types of intervention provided (education, breathing techniques, exercise prescription) were common across all services. Geographic location was associated with differences in airway clearance service models (greater use of regular clinics, telephone/telehealth consultations and dedicated cardiorespiratory physiotherapists in metropolitan locations versus clients incurring service and device provision costs in non-metropolitan regions). CONCLUSIONS While similarities in airway clearance interventions exist, differences in service models may disadvantage people living with chronic lung conditions, especially in non-metropolitan regions of Australia.

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
To identify the risk factors associated with all-cause mortality in patients with noncystic fibrosis bronchiectasis (NCFB). This prospective cohort study included 120 adult patients with NCFB, who were regularly treated at a specialized outpatient clinic of a university hospital between January 2017 and June 2020. All patients were diagnosed using high-resolution computed tomography. Demographic and clinical data, pulmonary function tests, and the Euro-quality-of-life 5-domain 3-level questionnaire were analyzed. The factors associated with death were determined using the Cox proportional hazards model. The all-cause mortality rate at 41 months was 10.8%. Adjusted multivariate analysis showed that the main contributing predictors for mortality were female sex, smoking, diabetes, chronic obstructive pulmonary disease, emergency visits, use of antibiotics due to exacerbation, secretion color change, exacerbation, predicted forced expiratory volume in 1 second, predicted forced vital capacity, lack of respiratory physiotherapy, absence of vaccination against pneumococci, and mobility domain. Multiple factors contribute to unfavorable outcomes in patients with NCFB, and early recognition of these factors may improve care management.

Abstract
BackgroundRisk factors for COPD in high-income settings are well understood; however, less attention has been paid to contributors of COPD in low-income and middle-income countries (LMICs) such as pulmonary tuberculosis. We sought to study the association between previous tuberculosis disease and COPD by using pooled population-based cross-sectional data in 13 geographically diverse, low-resource settings.MethodsWe pooled six cohorts in 13 different LMIC settings, 6 countries and 3 continents to study the relationship between self-reported previous tuberculosis disease and lung function outcomes including COPD (defined as a postbronchodilator forced expiratory volume in one second (FEV1)/forced vital capacity (FVC) below the lower limit of normal). Multivariable regressions with random effects were used to examine the association between previous tuberculosis disease and lung function outcomes.ResultsWe analysed data for 12 396 participants (median age 54.0 years, 51.5% male); 332 (2.7%) of the participants had previous tuberculosis disease. Overall prevalence of COPD was 8.8% (range 1.7%–15.5% across sites). COPD was four times more common among those with previous tuberculosis disease (25.7% vs 8.3% without previous tuberculosis disease, p<0.001). The adjusted odds of having COPD was 3.78 times higher (95% CI 2.87 to 4.98) for participants with previous tuberculosis disease than those without a history of tuberculosis disease. The attributable fraction of COPD due to previous tuberculosis disease in the study sample was 6.9% (95% CI 4.8% to 9.6%). Participants with previous tuberculosis disease also had lower prebronchodilator Z-scores for FEV1(−0.70, 95% CI −0.84 to −0.55), FVC (−0.44, 95% CI −0.59 to −0.29) and the FEV1:FVC ratio (−0.63, 95% CI −0.76 to −0.51) when compared with those without previous tuberculosis disease.ConclusionsPrevious tuberculosis disease is a significant and under-recognised risk factor for COPD and poor lung function in LMICs. Better tuberculosis control will also likely reduce the global burden of COPD.

Abstract
Due to their potent anti-inflammatory capacity (particularly in predominantly eosinophilic inflammation) and immunosuppressive properties, inhaled corticosteroids (ICSs) are widely used in asthmatic patients and also in individuals with chronic obstructive pulmonary disease (COPD) who suffer multiple exacerbations or have peripheral eosinophilia. However, there is little evidence for their use in non-cystic fibrosis bronchiectasis (hereafter, bronchiectasis). According to data extracted from large databases of bronchiectasis in adults, ICSs are used in more than 50% of patients without any scientific evidence to justify their efficacy and contrary to the recommendations of international guidelines on bronchiectasis that generally advise against their use. Indeed, bronchiectasis is a disease with predominantly neutrophilic inflammation and a high likelihood of chronic bacterial bronchial infection. Furthermore, it is known that due to their immunosuppressive properties, ICSs can induce an increase in bacterial infections. This manuscript aims to review the basic properties of ICSs, how they impact bronchiectasis in adults, the current position of international guidelines on this treatment, and the current indications and future challenges related to ICS use in bronchiectasis.

Abstract
BACKGROUND Bronchiectasis is a chronic pulmonary disease characterized by progressive and irreversible bronchial dilatation. The present study aimed to assess the clinical, demographic, microbiological, and radiological features of patients with bronchiectasis. METHODS The study population included 60 subjects with bronchiectasis diagnosed by HRCT, who attended the Department of Respiratory Medicine a tertiary care teaching center. A single examiner examined all the 60 participants. Pulmonary function assessment was done on all the subjects on a spirometer, and early-morning sputum samples were taken for culture and sensitivity. Descriptive analysis was carried out by mean and standard deviation for quantitative variables, frequency, and proportion for categorical variables. Categorical outcomes were compared between study groups using the chi-square test. P value <0.05 was considered statistically significant. Co-Guide was used for statistical analysis. RESULT The majority of the participants were males (62%). The most common sign observed was crepitations (75%). Pseudomonas aeruginosa (36%) was the primary pathogen isolated from sputum, followed by Klebsiella pneumonia (20%). Drug resistance was highest for ampicillin (56%), and imipenem (100%) was the most sensitive drug. CONCLUSION Bronchiectasis is a heterogeneous entity with varied etiologies and multifarious clinic-radiological patterns. The information on etiology and the causative microorganism and antibiotic sensitivity and resistance aids in providing early treatment and thereby improving the lung function of affected individuals.

Abstract
Neisseria species are frequently identified in the bronchiectasis microbiome, but they are regarded as respiratory commensals. Using a combination of human cohorts, next-generation sequencing, systems biology, and animal models, we show that bronchiectasis bacteriomes defined by the presence of Neisseria spp. associate with poor clinical outcomes, including exacerbations. Neisseria subflava cultivated from bronchiectasis patients promotes the loss of epithelial integrity and inflammation in primary epithelial cells. In vivo animal models of Neisseria subflava infection and metabolipidome analysis highlight immunoinflammatory functional gene clusters and provide evidence for pulmonary inflammation. The murine metabolipidomic data were validated with human Neisseria-dominant bronchiectasis samples and compared with disease in which Pseudomonas-, an established bronchiectasis pathogen, is dominant. Metagenomic surveillance of Neisseria across various respiratory disorders reveals broader importance, and the assessment of the home environment in bronchiectasis implies potential environmental sources of exposure. Thus, we identify Neisseria species as pathobionts in bronchiectasis, allowing for improved risk stratification in this high-risk group.

Identification of Enterocytozoon bieneusi in an HIV-negative bronchiectasis patient with respiratory infection based on metagenomic next-generation sequencing: A case report. Indian J Med Microbiol 2022; 42:97-99. [PMID: 36114063 DOI: 10.1016/j.ijmmb.2022.07.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 04/24/2022] [Accepted: 07/29/2022] [Indexed: 11/21/2022]
Abstract
Bronchiectasis is often caused by serious infections. Infections caused by Enterocytozoon bieneusi (E. bieneusi) is most common in the immunocompromised host, such as HIV-positive patients. Herein, we reported an HIV-negative patient with bronchiectasis infected with E. bieneusi, which diagnosed by mNGS and validated by Sanger sequencing. During the treatment of albendazole, the patient gradually recovered. This is the first report of a case of respiratory E. bieneusi infection in a bronchiectasis patient. This finding highlights the efficacy of mNGS for pathogen diagnosis in bronchiectasis patients and the potential treatment option of albendazole for bronchiectasis patients with E. bieneusi infection.

Abstract
BACKGROUND/AIMS Patients with bronchiectasis often present with respiratory symptoms caused by chronic rhinosinusitis (CRS). However, studies on the prevalence of CRS and its relationship with bronchiectasis are limited. METHODS The baseline characteristics of patients with bronchiectasis recruited from the Korean Multicenter Bronchiectasis Audit and Research Collaboration were analyzed. CRS diagnosis was determined by a physician, on the basis of medical records, upper airway symptoms, and/or radiologic abnormalities. Questionnaires for quality of life, fatigue, and depression were administered when patients were stable for a minimum of 4 weeks after the bronchiectasis exacerbation. RESULTS The prevalence of CRS was 7.1% (66/931). Patients with CRS were significantly younger than those without CRS (60.5 ± 10.7 years vs. 64.6 ± 9.3 years, p = 0.001). Idiopathic bronchiectasis was more common in patients with CRS compared to those without CRS (53.0% vs. 36.0%, p = 0.006). Lung function, inflammatory markers, exacerbations, bronchiectasis severity, and scores for quality of life, fatigue, and depression did not differ between the two groups. In a logistic regression analysis, CRS was associated with age of bronchiectasis diagnosis (odds ratio [OR], 0.96; 95% confidence interval [CI], 0.94 to 0.99; p = 0.003) and idiopathic bronchiectasis (OR, 1.95; 95% CI, 1.12 to 3.34; p = 0.018). CONCLUSION The prevalence of CRS was relatively low. CRS was not associated with the severity or clinical outcomes of bronchiectasis. Early diagnosis and idiopathic etiology were associated with CRS. Our findings reflect the low recognition of CRS in the clinical practice of bronchiectasis and highlight the need for awareness of CRS by adopting objective diagnostic criteria.

Proportionate clinical burden of respiratory diseases in Indian outdoor services and its relationship with seasonal transitions and risk factors: The results of SWORD survey. PLoS One 2022; 17:e0268216.

Abstract
Background The Global Burden of Disease data suggest that respiratory diseases contribute to high morbidity in India. However, the factors responsible for high morbidity are not quite clear. Therefore, the Seasonal Waves Of Respiratory Disorders (SWORD) study was planned to estimate the point prevalence due to respiratory diseases in Indian OPD services and its association with risk factors and change in seasons. Methods In this point prevalence observational multicenter study conducted during 2017–18, participating physicians recorded information of consecutive patients in response to a questionnaire. The study was conducted on four predetermined days representing transition of Indian seasons i.e., February (winter), May (summer), August (monsoon), and November (autumn). Results The eligible number of patients from across 302 sites in India was 25,177. The mean age of study population was 46.1±18.1 years, 14102(56.0%) were males and 11075(44.0%) females. The common diagnoses were: asthma(29.8%), chronic obstructive pulmonary disease (COPD),15.6%, respiratory tract infections (RTIs),11.3%, and tuberculosis(8.7%). All these conditions showed significant seasonal trends (Asthma 31.4% autumn vs. 26.5% summer, COPD 21.1% winter vs. 8.1% summer, RTIs 13.3% winter vs. 4.3% summer, and tuberculosis 12.5% autumn vs. 4.1% summer, p<0.001 for each respectively). After adjustment for risk factors, asthma was significantly associated with exposure to molds (OR:1.12,CI:1.03–1.22), pet animals (OR:1.07,CI:1.01–1.14), recent-travel (OR:1.22,CI:1.13–1.32), and rain-wetting (OR:1.27,CI:1.15–1.40); and RTIs with rain-wetting (OR:1.53,CI:1.34–1.74), and recent-travel (OR:1.17,CI:1.05–1.30). Conclusions The SWORD study showed wide seasonal variations in outpatient attendance of patients with common respiratory conditions. Novel risk-factors associated with respiratory diseases were also identified.

BMC Pulm Med 2022; 22:309. [PMID: 35962350 PMCID: PMC9372940 DOI: 10.1186/s12890-022-02101-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 08/01/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Tuberculosis (TB) is one of the main infectious diseases that seriously threatens global health, while diagnostic delay (DD) and treatment dramatically threaten TB control. METHODS Between 2005 and 2017 in Shandong, China, we enrolled pulmonary tuberculosis (PTB) patients with DD. DD trends were evaluated by Joinpoint regression, and associations between PTB patient characteristics and DD were estimated by univariate and multivariate logistic regression. The influence of DD duration on prognosis and sputum smear results were assessed by Spearman correlation coefficients. RESULTS We identified 208,822 PTB cases with a median DD of 33 days (interquartile range (IQR) 18-63). The trend of PTB with DD declined significantly between 2009 and 2017 (annual percent change (APC): - 4.0%, P = 0.047, 2009-2013; APC: - 6.6%, P = 0.001, 2013-2017). Patients aged > 45 years old (adjusted odds ratio (aOR): 1.223, 95% confidence interval (CI) 1.189-1.257, 46-65 years; aOR: 1.306, 95% CI 1.267-1.346, > 65 years), farmers (aOR: 1.520, 95% CI 1.447-1.596), and those with a previous treatment history (aOR: 1.759, 95% CI 1.699-1.821) were prone to developing long DD (> 30 days, P < 0.05). An unfavorable outcome was negatively associated with a short DD (OR: 0.876, 95% CI 0.843-0.910, P < 0.001). Sputum smear positive rate and unfavorable outcomes were positively correlated with DD duration (Spearman correlation coefficients (rs) = 1, P < 0.001). CONCLUSIONS The DD situation remains serious; more efficient and comprehensive strategies are urgently required to minimize DD, especially for high-risk patients.

Abstract
OBJECTIVE To accurately estimate the global prevalence of non-tuberculous mycobacteria (NTM) in adults with non-cystic fibrosis (non-CF) bronchiectasis and to determine the proportion of NTM species and subspecies in clinical patients from 2006 to 2021. DESIGN Systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SOURCES Medline, Embase, Cochrane Library and Web of Science were searched for articles published between 2006 and 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES We included all the prospective or retrospective studies without language restrictions and all patients were adults (≥18 years of age) with non-CF bronchiectasis. The studies estimated the effect size of the prevalence of NTM with a sample size ≥40, and patients were registered in and after 2006. DATA EXTRACTION AND SYNTHESIS Two reviewers screened the titles, abstracts and full texts independently. Relevant information was extracted and curated into tables. Risk of bias was evaluated following the Cochrane Collaboration's tool. Meta-analysis was performed with software R Statistics V.3.6.3 using random effect model with 95% CI. I2 index and Q statistics were calculated to assess the heterogeneity, and mixed-effects meta-regression analyses were performed to identify the sources of heterogeneity. The proportions of NTM subspecies were examined using Shapiro-Wilk normality test in R. RESULTS Of all the 2014 studies yielded, 24 met the inclusion criteria. Of these, 14 were identified to be randomised controlled studies and included for an accurate estimation. The global prevalence of NTM in adults with non-CF bronchiectasis from 2006 to 2021 was estimated to be approximately 10%, with great variations primarily due to geographical location. Mycobacterium avium complex was the most common subspecies, followed by Mycobacterium simiae and Mycobacterium gordonae. CONCLUSIONS The prevalence of NTM in adults with non-CF bronchiectasis has been on the rise and the most common subspecies changed greatly in recent years. More cohort studies should be done in many countries and regions for future estimates. PROSPERO REGISTRATION NUMBER CRD42020168473.

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
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
Rationale: Bronchiectasis is classically considered a neutrophilic disorder, but eosinophilic subtypes have recently been described. Objectives: To use multiple datasets available through the European Multicentre Bronchiectasis Audit and Research Collaboration to characterize eosinophilic bronchiectasis as a clinical entity focusing on the impact of eosinophils on bronchiectasis exacerbations. Methods: Patients were included from five countries to examine the relationships between blood eosinophil counts and clinical phenotypes after excluding coexisting asthma. 16S rRNA sequencing was used to examine relationships between eosinophil counts and the sputum microbiome. A post hoc analysis of the PROMIS (Inhaled Promixin in the Treatment of Non-Cystic Fibrosis Bronchiectasis) phase 2 trial was used to examine the impact of blood eosinophil counts on exacerbations in patients with Pseudomonas aeruginosa infection. Measurements and Main Results: A relationship between sputum and blood eosinophil counts was demonstrated in two cohorts. In analysis of 1,007 patients from five countries, 22.6% of patients had blood eosinophil counts of ⩾300 cells/μl. Counts of <100 cells/μl were associated with higher bronchiectasis severity and increased mortality. There was no clear relationship with exacerbations. Blood eosinophil counts of ⩾300 cells/μl were associated with both Streptococcus- and Pseudomonas-dominated microbiome profiles. To investigate the relationship of eosinophil counts with exacerbations after controlling for the confounding effects of infection, 144 patients were studied in a clinical trial after treatment with antipseudomonal antibiotics. Compared with patients with blood eosinophil counts of <100 cells/μl (reference), elevated eosinophil counts of 100-299 cells/μl (hazard ratio, 2.38; 95% confidence interval, 1.33-4.25; P = 0.003) and ⩾300 cells/μl (hazard ratio, 3.99; 95% confidence interval, 2.20-7.85; P < 0.0001) were associated with shorter time to exacerbation. Conclusions: Eosinophilic bronchiectasis affects approximately 20% of patients. After accounting for infection status, raised blood eosinophil counts are associated with shortened time to exacerbation.

Abstract
BACKGROUND Guidelines aim to standardize and optimize diagnosis and management. We evaluated the quality of evidence supporting recommendations from different international adult guidelines on bronchiectasis, and classified with the GRADE system. METHODS Quality of eligible clinical practice guidelines was assessed for six domains using the AGREE II tool, with ≥ 80% rating as excellent. RESULTS Seven guidelines (283 recommendations) were analyzed, and four of them were considered "recommended for use" (three reported after 2017 as excellent). Overall, 144 (50.9%) recommendations were based on low-quality evidence, representing 81.5% in diagnosis and 36.2% in therapy. In contrast, 5/92 (5.4%) and 40/191 (20.9%) recommendations regarding diagnostic and treatment (respectively) were based on high-quality evidence. Quality agreement ratings were significantly (p< 0.05) higher for guidelines delivered after 2015, progressing from 27.7% to 58.3%, qualifying as excellent. Highest scores were documented in the domains of "scope and purpose" followed by "clarifying of presentation" and "editorial independence". CONCLUSION Updated guidelines reported after 2017 improved quality, although well-designed randomized clinical trials remain an unmet need. AGREE II quality assessment identified four guidelines qualified as recommended for use. Improvements are required in stakeholder involvement and applicability.

Abstract
Background Pulmonary impairment after tuberculosis treatment is seen in 40%-75% of patients despite bacteriological cure. Study aimed to find prevalence of structural and functional pulmonary impairment in a group of previously fit serving soldiers at the end of supervised institutional treatment for pulmonary tuberculosis. Methods Descriptive cross-sectional study was conducted in a tertiary care center on 375 newly diagnosed patients of pulmonary tuberculosis completed treatment. They underwent spirometry and chest X ray (CXR) at end of treatment. Their lung function was classified as normal or abnormal (obstructive, restrictive, or mixed pattern). Chest radiographs were reported as normal/abnormal. Logistic regression models were used to explore the factors associated with abnormal lung function. Results Functional impairment was present in 145/375 (38.7%). 115/375 (30.66%) had restrictive, 24/375 (6.4%) had mixed, and 6/375 (1.6%) had obstructive pattern on spirometry, respectively. Out of the 115 patients having restrictive pattern, 103 (89.56%) had mild restriction, 11(9.56%) had moderate restriction, and 1 (0.86%) had severe restriction. Structural impairment on CXR was present in 309/375 (82.4%) of patients. Significant factors associated with pulmonary impairment in our study were time to diagnosis (>1 month) adj odds ratio (OR) = 1.71, 95% confidence interval (CI) 1.07-2.74, sputum conversion of >2 months, Adj OR 2.52, 95% CI 1.25-5.07, and sputum/culture positivity Adj OR 1.57, 95% CI 1.02-2.42. CXR abnormality was significantly associated with sputum and/culture positivity Adj OR 4.54, 95% CI 2.28-9.03. Conclusion Despite successful treatment, pulmonary impairment was present in 38.7% of patients, and structural changes evident on CXR was present in 82.4% of patients.

Abstract
Chronic lung diseases are the third leading cause of death worldwide and are increasing in prevalence over time. Although much of our traditional understanding of health and disease is derived from study of the male of the species - be it animal or human - there is increasing evidence that sex and gender contribute to differences in disease risk, prevalence, presentation, severity, treatment approach, response and outcomes. Chronic obstructive pulmonary disease, asthma and bronchiectasis represent the most prevalent and studied chronic lung diseases and have key sex- and gender-based differences which are critical to consider and incorporate into clinical and research approaches. Mechanistic differences present opportunities for therapeutic development whereas behavioural and clinical differences on the part of patients and providers present opportunities for greater education and understanding at multiple levels. In this review, we seek to summarise the sex- and gender-based differences in key chronic lung diseases and outline the clinical and research implications for stakeholders.

Abstract
Bronchiectasis is a debilitating chronic suppurative airway disease that confers a substantial burden globally. Despite the notable prevalence, research on bronchiectasis in mainland China remains in its infancy. Nevertheless, there has been a significant leap in the quantity and quality of research, which has contributed to the ever-improving clinical practice. A nationwide collaborative platform has been established to foster multicentre studies, which will help increase the level of evidence further. Here, we summarise the status quo of clinical management and consider the research priorities for bronchiectasis that have been published previously. We also highlight the efforts of the Chinese medical communities to outline the core tasks that need to be addressed within the next decade. The remarkable progress made in bronchiectasis research has revolutionised clinical practice in mainland Chinahttps://bit.ly/3K8kQYr

Abstract
SummaryHabitual cough suppression leading to non-tuberculous mycobacteria infections and bronchiectasis has been reported. We present a case of a 55-year-old woman with a chronic history of cough with mild expectoration and frequent lower respiratory tract infections, remitting with antibiotic therapy and other supportive measures. She also reported habitual cough suppression for several years. She was eventually diagnosed with Mycobacterium avium complex (MAC) positive right middle lobe bronchiectasis-Lady Windermere syndrome and obstructive sleep apnoea (OSA), causing disabling symptoms limiting her daily activities. We aim to highlight two key issues-diagnosing MAC infections in a tuberculosis endemic country, and OSA and its long-term clinical implications.

Abstract
Bronchiectasis refers to both a clinical disease and a radiological appearance that has multiple causes and can be associated with a range of conditions. Disease heterogeneity and the absence of standardised definitions have hampered clinical trials of treatments for bronchiectasis and are important challenges in clinical practice. In view of the need for new therapies for non-cystic fibrosis bronchiectasis to reduce the disease burden, we established an international taskforce of experts to develop recommendations and definitions for clinically significant bronchiectasis in adults to facilitate the standardisation of terminology for clinical trials. Systematic reviews were used to inform discussions, and Delphi processes were used to achieve expert consensus. We prioritised criteria for the radiological diagnosis of bronchiectasis and suggest recommendations on the use and central reading of chest CT scans to confirm the presence of bronchiectasis for clinical trials. Furthermore, we developed a set of consensus statements concerning the definitions of clinical bronchiectasis and its specific signs and symptoms, as well as definitions for chronic bacterial infection and sustained culture conversion. The diagnosis of clinically significant bronchiectasis requires both clinical and radiological criteria, and these expert recommendations and proposals should help to optimise patient recruitment into clinical trials and allow reliable comparisons of treatment effects among different interventions for bronchiectasis. Our consensus proposals should also provide a framework for future research to further refine definitions and establish definitive guidance on the diagnosis of bronchiectasis.
