[PMID: 38946716 PMCID: PMC11212557 DOI: 10.1080/20018525.2024.2372901] [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: 11/27/2023] [Accepted: 06/04/2024] [Indexed: 07/02/2024] Open
Abstract
Background Bronchiectasis is a disease with predominantly neutrophilic inflammation. As a readily available biomarker, there is little evidence to support the use of blood neutrophil-to-lymphocyte ratio (NLR) to predict bronchiectasis exacerbation severe enough to warrant hospitalization. Methods A registry-based retrospective cohort study was conducted at a in Hong Kong. Chinese patients with non-cystic fibrosis (CF) bronchiectasis were retrospectively reviewed and subsequently followed up to investigate the association of NLR and the need for hospitalization for bronchiectasis exacerbation. Data on the NLR for patients in a clinically stable state in 2018 were collected and patients followed up from 1 January 2019 to 31 December 2022. The primary outcome was the need for hospitalization due to bronchiectasis exacerbation over the next 4 years. Results We reviewed 473 Chinese patients with non-CF bronchiectasis, of whom 94 required hospitalization for bronchiectasis exacerbation during the 4-year follow-up period. Multi-variable logistic regression adjusted for E-FACED score (Exacerbation, Forced expiratory volume in 1 s (FEV1), Age, Chronic colonization, Extension, and Dyspnea score), gender, age, smoking status, and presence of co-existing chronic obstructive pulmonary disease (COPD) was conducted to compare patients with highest and lowest quartile NLR. Results revealed that those with NLR at the highest quartile were at increased risk of hospitalization for bronchiectasis exacerbation with an adjusted odds ratio (aOR) of 2.02 (95% confidence interval = 1.00-4.12, p = 0.05). Conclusion Blood NLR may serve as a marker to predict the need for hospitalization due to bronchiectasis exacerbation.

[PMID: 38818499 PMCID: PMC11139531 DOI: 10.1155/2024/8884030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 01/22/2024] [Accepted: 05/11/2024] [Indexed: 06/01/2024] Open
Abstract
Methods Participants underwent respiratory muscle training for 24 weeks. The main results were changes in respiratory muscle strength and pulmonary function indices (forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC, peak expiratory flow rate (PEF), forced expiratory flow 25-75% (FEF25-75%), and maximal midexpiratory flow 75/25 (MMEF75/25)) before, 12 weeks after, and 24 weeks after the intervention. The secondary outcomes were changes in the exercise load and work rate, exercise work, Leicester Cough Questionnaire (LCQ) scale, and Fatigue Severity Scale (FSS). Results Compared with before the intervention, after 24 weeks of respiratory muscle training, the maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were significantly enhanced (P < 0.05), while FVC, FEV1, and PEF were significantly increased (P < 0.01). FEF25-75 and MMEF75/25 values showed significant improvement compared to those before training (P < 0.05). The exercise loading, work, and exercise work rate of expiratory muscle training were significantly improved compared to those before intervention (P < 0.05). The LCQ score increased significantly (P < 0.001), and the FSS score decreased significantly (P < 0.001). Conclusion Incremental load respiratory muscle training effectively improved children's lung function over the long term, improved the strength of their inspiratory and expiratory muscles, and improved their quality of life.

Abstract
INTRODUCTION Bronchiectasis is a worldwide chronic lung disorder where exacerbations are common. It affects people of all ages, but especially Indigenous populations in high-income nations. Despite being a major contributor to chronic lung disease, there are no licensed therapies for bronchiectasis and there remain relatively few randomised controlled trials (RCTs) conducted in children and adults. Our RCT will address some of these unmet needs by evaluating whether the novel mucoactive agent, erdosteine, has a therapeutic role in children and adults with bronchiectasis.Our primary aim is to determine in children and adults aged 2-49 years with bronchiectasis whether regular erdosteine over a 12-month period reduces acute respiratory exacerbations compared with placebo. Our primary hypothesis is that people with bronchiectasis who regularly use erdosteine will have fewer exacerbations than those receiving placebo.Our secondary aims are to determine the effect of the trial medications on quality of life (QoL) and other clinical outcomes (exacerbation duration, time-to-next exacerbation, hospitalisations, lung function, adverse events). We will also assess the cost-effectiveness of the intervention. METHODS AND ANALYSIS We are undertaking an international multicentre, double-blind, placebo-RCT to evaluate whether 12 months of erdosteine is beneficial for children and adults with bronchiectasis. We will recruit 194 children and adults with bronchiectasis to a parallel, superiority RCT at eight sites across Australia, Malaysia and Philippines. Our primary endpoint is the rate of exacerbations over 12 months. Our main secondary outcomes are QoL, exacerbation duration, time-to-next exacerbation, hospitalisations and lung function. ETHICS AND DISSEMINATION The Human Research Ethics Committees (HREC) of Children's Health Queensland (for all Australian sites), University of Malaya Medical Centre (Malaysia) and St. Luke's Medical Centre (Philippines) approved the study. We will publish the results and share the outcomes with the academic and medical community, funding and relevant patient organisations. TRIAL REGISTRATION NUMBER ACTRN12621000315819.

Abstract
BACKGROUND Elevation of systemic inflammatory markers were found to correlate with increased disease extent, reduced lung function and higher risk of future severe exacerbations in patients with bronchiectasis. Although a significant correlation of circulating hs-CRP levels with HRCT scores and resting oxygen saturation in patients with stable-state non-cystic fibrosis (CF) bronchiectasis was suggested, there is little data on the relationship between hs-CRP and the prognosis of bronchiectasis and a lack of data on the role of hs-CRP in predicting bronchiectasis exacerbation. METHODS A prospective study was conducted on Chinese patients with non- CF bronchiectasis from 1st October to 31st December 2021. Baseline serum hs-CRP were obtained at stable-state. The follow-up period lasted for one year. Co-primary endpoints were the development of any bronchiectasis exacerbation and hospitalized bronchiectasis exacerbation. RESULTS Totally 123 patients were included. Higher hs-CRP was associated with increased risk to develop any bronchiectasis exacerbation, adjusted odds ratio (aOR) of 2.254 (95% CI = 1.040-4.885, p = 0.039), and borderline significantly increased hospitalized bronchiectasis exacerbation with aOR of 1.985 (95% CI = 0.922-4.277, p = 0.080). CONCLUSION Baseline serum hs-CRP level at stable-state can predict risk of bronchiectasis exacerbation, which is reflecting chronic low-grade inflammation in bronchiectasis.

Phenotypic Features of Pediatric Bronchiectasis Exacerbations Associated With Symptom Resolution After 14 Days of Oral Antibiotic Treatment. Chest 2023; 164:1378-1386. [PMID: 37437879 DOI: 10.1016/j.chest.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 06/12/2023] [Accepted: 07/01/2023] [Indexed: 07/14/2023] Open
Abstract
BACKGROUND Respiratory exacerbations in children and adolescents with bronchiectasis are treated with antibiotics. However, antibiotics can have variable interindividual effects when treating exacerbations. RESEARCH QUESTION Can phenotypic features associated with symptom resolution after a 14-day course of oral antibiotics for a nonsevere exacerbation of bronchiectasis be identified? STUDY DESIGN AND METHODS Combining data from two multicenter randomized controlled trials, we identified 217 children with bronchiectasis assigned to at least 14 days of oral antibiotics to treat nonsevere (nonhospitalized) exacerbations. Univariable and then multivariable logistic regression were used to identify factors associated with symptom resolution within 14 days of commencing antibiotics. Identified associations were re-evaluated by mediation analysis. RESULTS Of the 217 study participants (52% male patients), 41% were Indigenous (Australian First Nations, New Zealand Māori, or Pacific Islander). The median age was 6.6 years (interquartile range, 4.0-10.1 years). By day 14, symptoms had resolved in 130 children (responders), but persisted in the remaining 87 children (nonresponders). Multivariable analysis found those who were Indigenous (adjusted OR [AOR], 3.59; 95% CI, 1.35-9.54) or showed new abnormal auscultatory findings (AOR, 3.85; 95% CI, 1.56-9.52) were more likely to be responders, whereas those with multiple bronchiectatic lobes at diagnosis (AOR, 0.66; 95% CI, 0.46-0.95) or higher cough scores when starting exacerbation treatment (AOR, 0.55; 95% CI, 0.34-0.90) were more likely to be nonresponders. Detecting a respiratory virus at the beginning of an exacerbation was not associated with antibiotic failure at 14 days. INTERPRETATION Children with Indigenous ethnicity, milder bronchiectasis, mild exacerbations (low reported cough scores), or new abnormal auscultatory signs are more likely to respond to appropriate oral antibiotics than those without these features. These patient and exacerbation phenotypes may assist clinical management and development of biomarkers to identify those whose symptoms are more likely to resolve after 14 days of oral antibiotics.

[PMID: 37237074 DOI: 10.1038/s41390-023-02591-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 03/16/2023] [Accepted: 03/20/2023] [Indexed: 05/28/2023]
Abstract
BACKGROUND This study summarized the available randomized controlled trials (RCTs) to assess the efficacy and safety of macrolides on pathogens, lung function, laboratory parameters, and safety in children with bronchiectasis. METHODS PubMed, EMBASE, and the Cochrane Library were searched for available papers published up to June 2021. The outcomes were the pathogens, adverse events (AEs), and the forced expiratory volume in one second (FEV1%) predicted. RESULTS Seven RCTs (633 participants) were included. The long-term use of macrolides reduced the risk of the presence of Moraxella catarrhalis (RR = 0.67, 95% CI: 0.30-1.50, P = 0.001; I2 = 0.0%, Pheterogeneity = 0.433), but not Haemophilus influenza (RR = 0.19, 95% CI: 0.08-0.49, P = 0.333; I2 = 57.0%, Pheterogeneity = 0.040), Streptococcus pneumonia (RR = 0.91, 95% CI: 0.61-1.35, P = 0.635; I2 = 0.0%, Pheterogeneity = 0.515), Staphylococcus aureus (RR = 1.01, 95% CI: 0.36-2.84, P = 0.986; I2 = 61.9%, Pheterogeneity = 0.033), and any pathogens present (RR = 0.61, 95% CI: 0.29-1.29, P = 0.195; I2 = 80.3%, Pheterogeneity = 0.006). Long-term macrolides had no effect on FEV1% predicted (WMD = 2.61, 95% CI: -1.31, 6.53, P = 0.192; I2 = 0.0%, Pheterogeneity = 0.896). Long-term macrolides did not increase the risk of AEs or serious AEs. CONCLUSION Macrolides do not significantly reduce the risk of pathogens present (except for Moraxella catarrhalis) or increase FEV1% predicted among children with bronchiectasis. Moreover, macrolides were not associated with AEs. Considering the limitations of the meta-analysis, further larger-scale RCTs are needed to confirm the findings. IMPACT Macrolides do not significantly reduce the risk of pathogens present (except for Moraxella catarrhalis) among children with bronchiectasis. Macrolides do not significantly increase FEV1% predicted among children with bronchiectasis. This meta-analysis reports on the efficacy and safety of macrolides in the treatment of children with bronchiectasis, providing evidence for the management of children with bronchiectasis. This meta-analysis does not support the use of macrolides in the management of children with bronchiectasis unless the presence of Moraxella catarrhalis is provenor suspected.

Abstract
INTRODUCTION The current study aims to investigate the etiology spectrum and the clinical characteristics of bronchiectasis in Chinese children. METHODS The study is designed as a multicenter retrospective study. 193 cases were enrolled in 13 centers in China between 2008 and 2017. The inclusive cases must meet the clinical as well as the HRCT criteria. Only if both two radiologists confirmed the diagnosis, the case could be enrolled. The cases that could not provide clinical and imageology data were excluded. The data were entered into the specialized system and then analyzed. RESULTS One hundred sixty-nine cases (87%) were found to have the underlying etiology. Post-infective (46%), primary immunodeficiency (14%), and PCD (13%) were the common causes. All cases came from 28 provinces in Mainland China. The median age of symptom onset was 5.8 (2.0, 8.9) years. The median age of diagnosis was 8.4 (4.5, 11.6) years. The main symptoms were cough, sputum expectoration, and fever during the exacerbation. Nineteen percent of patients suffered from limited exercise tolerance. Clubbing was found in 17% of cases. Nearly 30% of patients presented growth limitations. On the HRCT findings, 126 cases had diffused bronchiectasis, and bilateral involvement was found in 94 cases. The lower lobes and right middle lobes were most commonly involved. Approximately 30% of cultures of sputum and bronchoalveolar lavage were positive. CONCLUSION A majority of cases could be found the underlying etiology. Post-infective, primary immunodeficiency, and PCD were the most common causes. Some clinical figures might indicate a specific etiology.

Abstract
Bronchiectasis is a pathologic state of conducting airways manifested radiographically by evidence of bronchial dilation and clinically by chronic productive cough. Considered an "orphan disease" for long, it remains a major contributor to morbidity and mortality in both developed and underdeveloped countries. With the advances in the medical field accompanied by widespread access to vaccines and antibiotics, improved health services and better access to nutrition, the incidences of bronchiectasis have markedly decreased, particularly in developed countries. This review summarizes the current knowledge pertaining to the clinical definition, etiology, clinical approach and management related to pediatric bronchiectasis.

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

Abstract
OBJECTIVE To discuss surgery for non-cystic fibrosis [CF] bronchiectasis in children and adolescents. SOURCES Non-systematic review including articles in English, mainly from the last 5 years. SUMMARY OF FINDINGS In this review, we present that in low- and middle-income countries [LMIC] clinical treatment fails in around 20% of cases due to low socioeconomic status and poor adherence. This causes the disease to progress and require surgery. We emphasize that the indications for surgery are not well defined and must be considered on an individual basis. The surgical treatment of bronchiectasis in children may be indicated in selected cases; especially in localized disease with frequent exacerbations despite an optimized clinical approach. Surgery can improve quality of life [QoL] and reduce exacerbations. It has few postoperative complications and low morbidity and mortality. Finally, we propose an algorithm for managing bronchiectasis, which takes into account LMIC settings with limited resources. CONCLUSION We conclude that in LMICs, surgery is a treatment strategy for selected children/adolescents with bronchiectasis.

Abstract
The global burden of bronchiectasis in children and adolescents is being recognised increasingly. However, marked inequity exists between, and within, settings and countries for resources and standards of care afforded to children and adolescents with bronchiectasis compared with those with other chronic lung diseases. The European Respiratory Society (ERS) clinical practice guideline for the management of bronchiectasis in children and adolescents was published recently. Here we present an international consensus of quality standards of care for children and adolescents with bronchiectasis based upon this guideline. The panel used a standardised approach that included a Delphi process with 201 respondents from the parents and patients' survey, and 299 physicians (across 54 countries) who care for children and adolescents with bronchiectasis. The seven quality standards of care statements developed by the panel address the current absence of quality standards for clinical care related to paediatric bronchiectasis. These internationally derived, clinician-, parent- and patient-informed, consensus-based quality standards statements can be used by parents and patients to access and advocate for quality care for their children and themselves, respectively. They can also be used by healthcare professionals to advocate for their patients, and by health services as a monitoring tool, to help optimise health outcomes.

Abstract
Bronchiectasis, characterised by chronic wet/productive cough with recurrent respiratory exacerbations and abnormal bronchial dilatation on computed tomography scans, remains an increasingly recognised but often neglected chronic pulmonary disorder in children and adolescents. An early diagnosis combined with optimal management offers the prospect, at least in some patients, of curing a condition previously considered irreversible. However, unlike in adults, until now no international paediatric guidelines existed. The recently published European Respiratory Society clinical practice guidelines for the management of children and adolescents with bronchiectasis attempts to address this clinical information gap. The guidelines were formulated by panel members comprised of experts from several relevant health fields, the European Lung Foundation and parents of children with bronchiectasis. Systematic reviews and the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach guided the nature and strength of recommendations. The recommendations are grouped into clinically relevant topics: diagnosis, evaluating for underlying causes, defining exacerbations, management, systematic care, monitoring, reversibility and prevention. The guidelines seek to achieve: 1) optimal lung growth, 2) preserved lung function, 3) enhanced quality of life, 4) minimal exacerbations, 5) few or no complications, and 6) if possible, reversal of lung injury for each child/adolescent with bronchiectasis. This review presents example cases that highlight the recommendations of the clinical practice guidelines. An international guideline for managing children/adolescents with bronchiectasis is now availablehttps://bit.ly/3A3XYnN

Abstract
Bronchiectasis (not related to cystic fibrosis) is a chronic lung disease caused by a range of etiologies but characterized by abnormal airway dilatation, recurrent respiratory symptoms, impaired quality of life and reduced life expectancy. Patients typically experience episodes of chronic wet cough and recurrent pulmonary exacerbations requiring hospitalization. Early diagnosis and management of childhood bronchiectasis are essential to prevent respiratory decline, optimize quality of life, minimize pulmonary exacerbations, and potentially reverse bronchial disease. Disease monitoring potentially allows for (1) the early detection of acute exacerbations, facilitating timely intervention, (2) tracking the rate of disease progression for prognostic purposes, and (3) quantifying the response to therapies. This narrative review article will discuss methods for monitoring disease progression in children with bronchiectasis, including lung imaging, respiratory function, patient-reported outcomes, respiratory exacerbations, sputum biomarkers, and nutritional outcomes.

Abstract
Bronchiectasis (BE) is a chronic condition affecting the bronchial tree. It is characterized by the dilatation of large and medium-sized airways, secondary to damage of the underlying bronchial wall structural elements and accompanied by the clinical picture of recurrent or persistent cough. Despite an increased awareness of childhood BE, there is still a paucity of data on the epidemiology, pathophysiological phenotypes, diagnosis, management, and outcomes in Africa where the prevalence is mostly unmeasured, and likely to be higher than high-income countries. Diagnostic pathways and management principles have largely been extrapolated from approaches in adults and children in high-income countries or from data in children with cystic fibrosis. Here we provide an overview of pediatric BE in Africa, highlighting risk factors, diagnostic and management challenges, need for a global approach to addressing key research gaps, and recommendations for practitioners working in Africa.

Abstract
INTRODUCTION Bronchiectasis is no longer considered rare or irreversible in children, yet it remains relatively under-researched and neglected in respiratory health globally. Bronchiectasis (including chronic suppurative lung disease) causes substantial morbidity for patients and significant impact on caregivers, especially during acute respiratory exacerbations. In other chronic respiratory diseases (eg, asthma), empowering consumers with an individualised plan for management of acute exacerbations improves clinical outcomes. However, in the absence of any such data specific to bronchiectasis, action management plans are rarely currently used in children or adults with bronchiectasis. We hypothesise that providing an individualised bronchiectasis action management plan (BAMP) to children with bronchiectasis reduces non-scheduled doctor consultations, compared with not having a BAMP. METHODS AND ANALYSIS This multicentre, parallel, double-blind, randomised trial involving three urban Australian hospitals commenced in June 2018 and will include 198 children, aged <19 years with bronchiectasis who had 2 or more exacerbations in the previous 18 months. Children will be randomised to having an individualised BAMP or standard care (a decoy clinic letter). Primary caregivers will then be followed up monthly for 12 months. The primary outcome is the rate of acute non-scheduled doctor visits for respiratory exacerbations by 12 months. The main secondary outcomes are cough-specific quality of life scores at 6 and 12 months, overall exacerbation rate over 12 months, and proportion of children who received timely influenza vaccination by 30 May annually. ETHICS AND DISSEMINATION The Human Research Ethics Committees of the Northern Territory Department of Health and Menzies School of Heath Research and Queensland Children's Hospital approved the study. The results of the trial will be submitted for publication and the BAMP made available free online. TRIAL REGISTRATION NUMBER Australia and New Zealand Clinical Trials Register ACTRN12618000604202.

Abstract
Bronchiectasis is a neglected chronic respiratory condition. In children optimal appropriate management can halt the disease process, and in some cases reverse the radiological abnormality. This requires many facets, including parental/carer bronchiectasis-specific knowledge, for which there is currently no such published data. Further, the importance of patient voices in guiding clinical research is becoming increasingly appreciated. To address these issues, we aimed to describe the voices of parents of children with bronchiectasis relating to (a) burden of illness and quality of life (QoL), (b) their major worries/concerns and (c) understanding/management of exacerbations. The parents of 152 children with bronchiectasis (median age = 5.8 years, range 3.5-8.4) recruited from the Queensland Children's Hospital (Australia) completed questionnaires, including a parent-proxy cough-specific QoL. We found that parents of children with bronchiectasis had impaired QoL (median 4.38, range 3.13-5.63) and a high disease burden with median 7.0 (range 4.0-10.0) doctor visits in 12-months. Parental knowledge varied with only 41% understanding appropriate management of an exacerbation. The highest worry/concern expressed were long-term effects (n = 42, 29.8%) and perceived declining health (n = 36, 25.5%). Our study has highlighted the need for improved education, high parental burden and areas of concern/worry which may inform development of a bronchiectasis-specific paediatric QoL tool.

Effect of azithromycin on incidence of acute respiratory exacerbations in children with HIV taking antiretroviral therapy and co-morbid chronic lung disease: a secondary analysis of the BREATHE trial. EClinicalMedicine 2021; 42:101195. [PMID: 34820609 PMCID: PMC8599092 DOI: 10.1016/j.eclinm.2021.101195] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2021] [Revised: 10/23/2021] [Accepted: 10/25/2021] [Indexed: 11/03/2022] Open
Abstract
BACKGROUND In the BREATHE trial weekly azithromycin decreased the rate of acute respiratory exacerbations (AREs) compared to placebo among children and adolescents with HIV-associated chronic lung disease (CLD) taking antiretroviral therapy (ART). The aim of this analysis was to identify risk factors associated with AREs and mediators of the effect of azithromycin on AREs. METHODS The primary outcome of this analysis was the rate of AREs by study arm up to 49 weeks. We analysed rates using Poisson regression with random intercepts. Interaction terms were fitted for potential effect modifiers. Participants were recruited from Zimbabwe and Malawi between15 June 2016 and 4 September 2018. FINDINGS We analysed data from 345 participants (171 allocated to azithromycin and 174 allocated to placebo). Rates of AREs were higher among those with an abnormally high respiratory rate at baseline (adjusted rate ratio (aRR) 2.08 95% CI 1.10-3.95 p-value 0.02) and among those with a CD4 cell count <200 cells/mm3 (aRR 2.71; 95% CI 1.27-5.76; p-value 0.008). We found some evidence for variation in the effect of azithromycin by sex (p-value for interaction=0.07); males had a greater reduction in the rate of ARE with azithromycin treatment than females. We found that azithromycin had a greater impact on reducing AREs in participants with chronic respiratory symptoms at baseline, those on 1st line ART, with a FEV1 score >-2 and participants without baseline resistance to azithromycin. However, there was no statistical evidence for interaction due to low statistical power. INTERPRETATION These may represent subgroups who may benefit the most from treatment with weekly azithromycin, which could help guide targeted treatment. FUNDING There was no funding source for this post hoc analysis.

Abstract
The limited resources and the practice of social distancing during the COVID pandemic create a paradigm shift in the utilization of telemedicine in healthcare. However, the implementation of best practices is hampered in part by a lack of literature devoted to telehealth in bronchiectasis. In this commentary, we examine multiple approaches to structuring of telemedicine care for patients with bronchiectasis, highlight current evidence-based interventions that can be incorporated into the management of bronchiectasis, and describe our experience with telemedicine at the University of Connecticut Center for Bronchiectasis Care during the COVID-19 pandemic. The structural model must be adapted to different local dynamics and available technologies with careful attention to patient characteristics and access to technology to avoid the potential paradoxical effects of increasing patients’ burden and healthcare disparities in underserved populations.

Factors associated with "Frequent Exacerbator" phenotype in children with bronchiectasis: The first report on children from the Australian Bronchiectasis Registry. Respir Med 2021; 188:106627. [PMID: 34592538 DOI: 10.1016/j.rmed.2021.106627] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 09/16/2021] [Accepted: 09/23/2021] [Indexed: 10/20/2022]
Abstract
INTRODUCTION In adults with bronchiectasis, multicentre data advanced the field including disease characterisation and derivation of phenotypes such as 'frequent exacerbator (FE)' (≥3 exacerbations/year). However, paediatric cohorts are largely limited to single centres and no scientifically derived phenotypes of paediatric bronchiectasis yet exists. Using paediatric data from the Australian Bronchiectasis Registry (ABR), we aimed to: (a) describe the clinical characteristics and compare Indigenous with non-Indigenous children, and (b) determine if a FE phenotype can be identified and if so, its associated factors. METHODS We retrieved data of children (aged <18-years) with radiologically confirmed bronchiectasis, enrolled between March 2016-March 2020. RESULTS Across five sites, 540 children [288 Indigenous; median age = 8-years (IQR 6-11)] were included. Baseline characteristics revealed past infection/idiopathic was the commonest (70%) underlying aetiology, most had cylindrical bronchiectasis and normal spirometry. Indigenous children (vs. non-Indigenous) had significantly more environmental tobacco smoke exposure (84% vs 32%, p < 0.0001) and lower birth weight (2797 g vs 3260 g, p < 0.0001). FE phenotype present in 162 (30%) children, was associated with being younger (ORadjusted = 0.85, 95%CI 0.81-0.90), more recent diagnosis of bronchiectasis (ORadjusted = 0.67; 95%CI 0.60-0.75), recent hospitalization (ORadj = 4.51; 95%CI 2.45-8.54) and Pseudomonas aeruginosa (PsA) infection (ORadjusted = 2.43; 95%CI 1.01-5.78). The FE phenotype were less likely to be Indigenous (ORadjusted = 0.14; 95%CI 0.03-0.65). CONCLUSION Even within a single country, the characteristics of children with bronchiectasis differ among cohorts. A paediatric FE phenotype exists and is characterised by being younger with a more recent diagnosis, PsA infection and previous hospitalization. Prospective data to consolidate our findings characterising childhood bronchiectasis phenotypes are required.

Abstract
BACKGROUND Noncystic fibrosis bronchiectasis (NCFB) is still considered an "orphan disease" in pediatric age. OBJECTIVE The study describes the clinical and functional features, the instrumental, and microbial findings of a large cohort of patients with NCFB, followed in a single tertiary level hospital. METHODS Children and adolescents diagnosed with NCFB from January 1, 2010 to December 31, 2019 were included. Data from the diagnosis and during the years of follow-up were recorded retrospectively. RESULTS One hundred and thirty-eight patients were enrolled. The most common cause of NCFB was postinfectious (33%), followed by primary ciliary dyskinesia (PCD) (30%), esophageal atresia (EA) (9.5%), and secondary immunodeficiency (9.5%). Chronic cough was the most frequent symptom. The median age of symptoms presentation was 3 years (interquartile age [IQR]: 12-84), with a precocious onset in PCD and EA groups. The median age of CT diagnosis was 9 years for all groups but PCD patients who were diagnosed at older age. Lingula, medium, upper, and lower lobes were more involved in PCD group, while diffuse distribution was observed in the postinfectious one. Microbial exams showed Pseudomonas aeruginosa colonization higher in PCD patients (22%). Despite microbial differences in airways colonization, no difference in respiratory exacerbation rate was recorded among groups. Lung function tests demonstrated the stability of forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) over time, except for the secondary immunodeficiency group. CONCLUSIONS The role of infections in developed countries should not be underestimated and a major effort to obtain an earlier identification of bronchiectasis should be taken. A prompt diagnosis of NFCB could help to reduce the frequency of exacerbations and improve the stability of lung function over time.

Abstract
The global burden of children and young people (CYP) with bronchiectasis is being recognised increasingly. They experience a poor quality of life and recurrent respiratory exacerbations requiring additional treatment, including hospitalisation. However, there are no published data on patient-driven clinical needs and/or research priorities for paediatric bronchiectasis. Parent/patient-driven views are required to understand the clinical needs and research priorities to inform changes that benefit CYP with bronchiectasis and reduce their disease burden. The European Lung Foundation and the European Respiratory Society Task Force for paediatric bronchiectasis created an international roadmap of clinical and research priorities to guide, and as an extension of, the clinical practice guideline. This roadmap was based on two global web-based surveys. The first survey (10 languages) was completed by 225 respondents (parents of CYP with bronchiectasis and adults with bronchiectasis diagnosed in childhood) from 21 countries. The parent/patient survey encompassed both clinical and research priorities. The second survey, completed by 258 health practitioners from 54 countries, was limited to research priorities. The two highest clinical needs expressed by parents/patients were: having an action management plan for flare-ups/exacerbations and access to physiotherapists. The two highest health practitioners’ research priorities related to eradication of airway pathogens and optimal airway clearance techniques. Based on both surveys, the top 10 research priorities were derived, and unanimous consensus statements were formulated from these priorities. This document addresses parents'/patients' clinical and research priorities from both the parents'/patients' and clinicians' perspectives and will help guide research and clinical efforts to improve the lives of people with bronchiectasis. This document is an international roadmap on parents’/patients’ clinical and research priorities from both the parents’/patients’ and clinicians’ perspectives to help guide research and clinical efforts to improve the lives of people with bronchiectasishttps://bit.ly/3xoonwi

Comparison of Profiles of First Nations and Non-First Nations Children With Bronchiectasis Over Two 5-Year Periods in the Northern Territory, Australia. Chest 2021; 160:1200-1210. [PMID: 33964302 DOI: 10.1016/j.chest.2021.04.057] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Revised: 03/11/2021] [Accepted: 04/16/2021] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Although the burden of bronchiectasis is recognized globally, pediatric data are limited, particularly on trends over the years. Also, no published data exists regarding whether vitamin D deficiency or insufficiency and human T-cell lymphotropic virus type 1 (HTLV-1) infection, both found to be related to severe bronchiectasis in First Nations adults, also are important in children with bronchiectasis. RESEARCH QUESTION Among children with bronchiectasis, (1) have the clinical and BAL profiles changed between two 5-year periods (period 1, 2007-2011; period 2, 2012-2016) and (b) are vitamin D deficiency or insufficiency, HTLV-1 infection, or both associated with radiologic severity of bronchiectasis? STUDY DESIGN AND METHODS We analyzed the data from children with bronchiectasis prospectively enrolled at Royal Darwin Hospital, Australia, at the first diagnosis; that is, no child was included in both periods. Data collected include demographics, BAL, bloods, and high-resolution CT scan of the chest evaluated using the Bhalla and modified Bhalla scores. RESULTS The median age of the 299 children was 2.2 years (interquartile range, 1.5-3.7 years). One hundred sixty-eight (56%) were male and most were First Nations (92%). Overall, bronchiectasis was high over time, particularly among First Nations children. In the later period, numbers of non-First Nations children more than tripled, but did not reach statistical significance. In period 2 compared with period 1, fewer First Nations children demonstrated chronic cough (period 1, 61%; period 2, 47%; P = .03), were younger, First Nations children were less likely to have received azithromycin (period 1, 42%; period 2, 21%; P < .001), and the BAL fluid of First Nations children showed lower Haemophilus influenzae and Moraxella catarrhalis infection. HTLV-1 infection was not detected, and vitamin D deficiency or insufficiency did not correlate with severity of bronchiectasis. INTERPRETATION Bronchiectasis remains high particularly among First Nations children. Important changes in their profiles that arguably reflect improvements were present, but overall, the profiles remained similar. Although vitamin D deficiency was uncommon, its role in children with bronchiectasis requires further evaluation. HTLV-1 infection was nonexistent and is unlikely to play any role in First Nations children with bronchiectasis.

[PMID: 33921227 PMCID: PMC8069972 DOI: 10.3390/ijerph18084024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 03/26/2021] [Accepted: 04/09/2021] [Indexed: 12/05/2022]
Abstract
BACKGROUND Hederacoside C from ivy leaf dry extracts (HH) and berberine from Coptidis rhizome dry extracts (CR) can be combined (HHCR) as a herbal product. Previous studies have demonstrated that HHCR has antitussive and expectorant effects in animal models of respiratory disease. However, the therapeutic effects of HHCR on respiratory diseases in humans have not been well-studied. Therefore, we aimed to clarify the effectiveness of HHCR in patients with chronic bronchitis and bronchiectasis. METHODS This was a multicenter (10 university teaching hospitals), open-label, prospective, single-arm, observational study. Consecutive patients with chronic bronchitis and bronchiectasis were included. Patients were orally treated with HHCR daily for 12 weeks. St. George's Respiratory Questionnaire (SGRQ) scores and bronchitis severity scores (BSS) were measured at baseline and at the end of the 12-week study. RESULTS In total, 376 patients were enrolled, of which 304 were finally included in the study, including 236 males and 68 females with a median age of 69 years (range: 37-88 years). After 12 weeks of HHCR treatment, there was a significant improvement in SGRQ score (baseline, 32.52 ± 16.93 vs. end of study, 29.08 ± 15.16; p < 0.0001) and a significant reduction in BSS (baseline, 7.16 ± 2.63 vs. end of study, 4.72 ± 2.45; p < 0.0001). During the study, 14 patients concomitantly used an inhaled corticosteroid and 83 patients used an inhaled bronchodilator. HHCR also had significant positive effects on these patients in terms of SGRQ score and BSS. No serious adverse drug reactions occurred during HHCR treatment. CONCLUSIONS treatment with HHCR improved the SGRQ score and BSS in patients with chronic bronchitis and bronchiectasis. HHCR may be a new therapeutic option for chronic bronchitis and bronchiectasis. Large-scale, randomized, double-blind, placebo-controlled clinical trials are warranted.

J Paediatr Child Health 2021; 57:548-553. [PMID: 33185946 DOI: 10.1111/jpc.15264] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 10/04/2020] [Accepted: 10/24/2020] [Indexed: 11/29/2022]
Abstract
AIM To determine whether the transfer of young people with cystic fibrosis (CF) or bronchiectasis from paediatric to adult services is associated with changes in service engagement and/or health outcomes. METHODS Young people aged ≥15 years of age with CF or bronchiectasis who transferred from the Auckland-based paediatric service (Starship Children's Hospital) to one of three Auckland-based District Health Boards between 2005 and 2012 were identified and included if they had 3 years care both pre-transfer and post-transfer care. Transfer preparation, service engagement (clinics scheduled, clinics attended) and health outcomes (lung function, hospitalisations) were collected per annum. RESULTS Fifty-seven young people transferred in this period with 46 meeting inclusion criteria (CF n = 20, bronchiectasis n = 26). The CF group had better transfer documentation, were transferred at an older age (11 months older P < 0.0001 95%CI: 6.7 months, 14.7 months), were 20 times more likely to attend clinics (P < 0.0001, 95%CI: 7.8, 66.1) and had 3-4 more clinics scheduled pre-transfer (P < 0.0001, 95%CI: 3.4, 4.9) and post-transfer (P < 0.0001, 95%CI: 2.4, 3.8) despite having less severe respiratory disease as measured by FEV1 for each year (P < 0.01, 95%CI: 0.34, 1.22). CONCLUSION The transfer of young people with CF to adult services did not affect health engagement or outcomes, in contrast to those with bronchiectasis. Use of a formalised transfer process, more clinic appointments offered and greater resources for CF may be responsible for this difference. Comprehensive transition with purposeful, planned movement and developmentally appropriate care is a key goal.

Abstract
There is increasing awareness of bronchiectasis in children and adolescents, a chronic pulmonary disorder associated with poor quality-of-life for the child/adolescent and their parents, recurrent exacerbations and costs to the family and health systems. Optimal treatment improves clinical outcomes. Several national guidelines exist, but there are no international guidelines.The European Respiratory Society (ERS) Task Force for the management of paediatric bronchiectasis sought to identify evidence-based management (investigation and treatment) strategies. It used the ERS standardised process that included a systematic review of the literature and application of the GRADE approach to define the quality of the evidence and level of recommendations.A multidisciplinary team of specialists in paediatric and adult respiratory medicine, infectious disease, physiotherapy, primary care, nursing, radiology, immunology, methodology, patient advocacy and parents of children/adolescents with bronchiectasis considered the most relevant clinical questions (for both clinicians and patients) related to managing paediatric bronchiectasis. Fourteen key clinical questions (7 "Patient, Intervention, Comparison, Outcome" [PICO] and 7 narrative) were generated. The outcomes for each PICO were decided by voting by the panel and parent advisory group.This guideline addresses the definition, diagnostic approach and antibiotic treatment of exacerbations, pathogen eradication, long-term antibiotic therapy, asthma-type therapies (inhaled corticosteroids, bronchodilators), mucoactive drugs, airway clearance, investigation of underlying causes of bronchiectasis, disease monitoring, factors to consider before surgical treatment and the reversibility and prevention of bronchiectasis in children/adolescents. Benchmarking quality of care for children/adolescents with bronchiectasis to improve clinical outcomes and evidence gaps for future research could be based on these recommendations.

Abstract
Background The prevalence of non-cystic fibrosis (CF) bronchiectasis is increasing in both developed and developing countries in recent years. Although the main features remain similar, etiologies seem to change. Our aim was to evaluate the clinical and laboratory characteristics of our recent non-CF bronchiectasis patients and to compare these with our historical cohort in 2001. Methods One hundred four children with non-CF bronchiectasis followed between 2002 and 2019 were enrolled. Age of diagnosis, underlying etiology and microorganisms in sputum culture were recorded. Clinical outcomes were evaluated in terms of lung function tests and annual pulmonary exacerbation rates at presentation and within the last 12 months. Results Mean FEV1 and FVC %predicted at presentation improved compared to historical cohort (76.6 ± 17.1 vs. 63.3 ± 22.1 and 76.6 ± 15.1 vs. 67.3 ± 23.1, respectively; p < 0.001). There was a significant decrease in pulmonary exacerbation rate from 6.05 ± 2.88 at presentation to 3.23 ± 2.08 during follow-up (p < 0.0001). In 80.8% of patients, an underlying etiology was identified. There was an increase in primary ciliary dyskinesia (PCD) (32.7% vs. 6.3%; p = 0.001), decrease in idiopathic cases (19.2% vs. 37.8%; p = 0.03) with no change in postinfectious and immunodeficiencies as underlying etiology. Sputum cultures were positive in 77.9% of patients which was 46.9% in the historical cohort (p = 0.001). Conclusion Baseline pulmonary function tests were better and distribution of underlying etiology had changed with a remarkable increase in diagnosis of PCD in the recent cohort.

Abstract
AIM Protracted bacterial bronchitis (PBB) is considered a potential precursor to bronchiectasis (BE) in some children. We previously showed that alveolar macrophages (AM) from children with PBB or BE have a similar significant defect in phagocytic capacity, with proinflammatory associations. We hypothesized that the mechanisms responsible for this defect involve dysregulation of the sphingosine-1-phosphate (S1P) signaling pathway, as we have found in adult inflammatory lung diseases. METHOD We employed a Custom TaqMan OpenArray to investigate gene expression of S1P-generating enzymes: sphingosine kinases (SPHK) 1/2, S1P phosphatase 2 (SGPP2), S1P lyase 1 (SGPL1), S1P receptors (S1PR) 1/2/4/5; proinflammatory cytokines TNF-α (TNF) and IFNγ (IFNG), the cytotoxic mediator granzyme B (GZMB), and inflammasomes AIM2 and NLRP3, in bronchoalveolar lavage from 15 children with BE, 15 with PBB and 17 age-matched controls, and determined association with clinical/demographic variables and airway inflammation. RESULT Significantly increased expression of S1PR1, S1PR2, and SPHK1 was noted in PBB and BE AM vs controls with increased SGPP2 only in PBB. TNF, IFNG, AIM2, and NLRP3 were significantly increased in both disease groups with increased GZMB only in PBB. There were no significant differences in the expression of any other S1P-related mediator between groups. There were significant positive associations between Haemophilus influenzae growth and expression of S1PR1 and NLRP3; between S1PR1 and S1PR2, NLRP3 and IFNG; between S1PR2 and AIM2, SPHK1, and SPHK2; and between SPHK1 and GZMB, IFNG, AIM2, and NLRP3. CONCLUSION Children with PBB and BE share similar S1P-associated gene expression profiles. AM phagocytic dysfunction and inflammation in these children may occur due to dysregulated S1P signaling.

Pediatric Patients of Outreach Specialist Queensland Clinics Have Lung Function Improvement Comparable to That of Tertiary Pediatric Patients. Chest 2020; 158:1566-1575. [PMID: 32387516 DOI: 10.1016/j.chest.2020.03.084] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Revised: 03/04/2020] [Accepted: 03/28/2020] [Indexed: 01/15/2023] Open
Abstract
BACKGROUND Inequitable access to quality health care contributes to the known poorer outcomes of people living in regional/remote areas (compared with urban-based), especially for First Nations people. Integration of specialist outreach services within primary care is one strategy that can reduce the inequity when modeled to the needs and available resources of target communities. RESEARCH QUESTION To evaluate whether respiratory outreach clinics in regional and remote Queensland are as effective as tertiary respiratory services at improving the lung function of children. STUDY DESIGN AND METHODS From existing databases, we obtained spirometry data of children (aged 3-18 years) seen at Indigenous-focused outreach clinics in regional and remote Queensland and Brisbane-based pediatric tertiary hospitals over the same contemporary period (October 2010 to July 2019). We compared the change in spirometry z scores (Δz) at follow-up for both groups of children. RESULTS Lung function significantly improved in both groups: Tertiary hospital (n = 2,249; ΔzFEV1 = 0.22, 95% CI, 0.17 to 0.27; ΔzFVC = 0.23, 95% CI, 0.18 to 0.28); outreach (n = 252; ΔzFEV1 = 0.35, 95% CI, 0.22 to 0.48; ΔzFVC = 0.36, 95% CI, 0.23 to 0.50). No significant intergroup differences were found in ΔzFEV1 (0.13; 95%CI, -0.02 to 0.28; P = .10) or ΔzFVC (0.14; 95% CI, -0.02 to 0.29; P = .08) improvement from baseline. In both groups, the proportion of children with zFEV1 > 0 at follow-up (hospital = 31.7%; outreach = 46.8%) significantly increased (hospital P = .001; outreach P = .009) from baseline (hospital = 27.2%; outreach = 35.3%). Numbers of children with zFEV1 > 0 significantly increased for asthma and bronchiectasis outreach subgroups, and for children with asthma in the hospital-based group. INTERPRETATION Comparable significant lung function improvement of children was seen in Indigenous-focused outreach remote/regional clinics and paediatric tertiary hospitals. This suggests that effective clinical care is achievable within the outreach setting.

Abstract
BACKGROUND AND OBJECTIVE Despite paediatric bronchiectasis being recognized increasingly worldwide, prior reports of hospitalization costs for bronchiectasis in children are lacking. This study aimed to (i) identify health service costs of hospitalizations and (ii) factors associated with these costs in children admitted to an Australian paediatric hospital following an acute exacerbation of their bronchiectasis. METHODS Demographic and hospital resource use data were prospectively recorded for 100 hospitalizations in 80 children aged <18 years admitted consecutively to the QCH, Brisbane, Australia. Costs (2016 AUD) were obtained from the hospital's Finance Department. Linear regressions, with bootstrap resampling to quantify uncertainty, were used to estimate factors affecting cost of hospitalization. RESULTS The 100 hospitalizations (48 males) had a median (IQR) age of 6.04 (4.04-9.85) years. Their mean (SD) LOS was 12.30 (4.60) days. The mean (SD) direct health service cost was AUD 30 182 (13 998) per hospitalization. The greatest contributor to costs was health professional wages, accounting for 70% of the cost per episode. LOS, younger age at admission and number of bronchiectatic lobes affected were associated with higher costs, whilst HITH service was associated with lower cost. The cost to families on average was AUD 2669.50 (SD: 991.50) per hospitalization when accounting for lost wages and opportunity cost. CONCLUSION The per episode healthcare cost burden of hospitalizations for paediatric bronchiectasis exacerbations is substantial. Interventions that prevent hospitalized exacerbations and reduce severity of childhood bronchiectasis with even moderate effectiveness are likely to result in substantial hospital costs savings.

Abstract
BACKGROUND AND OBJECTIVE Children with bronchiectasis have recurrent exacerbations and may require hospitalization. "Hospital in the home (HITH)" is used as an alternative to hospitalization for children with cystic fibrosis (CF) but to date, there is no published data on children without CF. We describe our experience of HITH (intravenous [IV] antibiotics and at least once-daily physiotherapy-treated airway clearance therapy) in a cohort of children with bronchiectasis, comparing outcomes between hospital and HITH-based pathways. METHODS Medical records were retrospectively reviewed in children with bronchiectasis who were hospitalized in our center from July 2016 to July 2018. We compared treatment duration, symptom resolution, adverse events, oral antibiotic prescription on discharge and "time-to-next hospitalization" between children managed with the two treatment pathways. RESULTS Exacerbations in 63 children (median age = 6 years [range: 1-17]; females = 33, indigenous = 8) with bronchiectasis treated with IV antibiotic therapy were analyzed (HITH n = 45, 71.5%). Duration of treatment and symptom resolution was similar between groups (hospital: median = 14 days [interquartile range {IQR}: 14-14] and 12/18 [66.6%], respectively vs HITH: 14 [14-15.5] and 31/45 [69%]; P = .53 and .85, respectively). There was no significant difference in adverse events (16.6% vs 9%), prescription of oral antibiotics on discharge (44% vs 24%), or "time-to-next hospitalization" (median 42 [IQR: 24-100] vs 67 [IQR: 32-95] weeks) between hospital and HITH groups, respectively. CONCLUSIONS In children with bronchiectasis treated for a severe exacerbation, receiving treatment in the home setting with HITH does not compromise short-term clinical outcomes compared to hospital only treatment. Prospective studies are required to provide more robust evidence in this under-researched area.

A decade on: Follow-up findings of indigenous children with bronchiectasis. Pediatr Pulmonol 2020; 55:975-985. [PMID: 32096916 DOI: 10.1002/ppul.24696] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Accepted: 02/08/2020] [Indexed: 12/25/2022]
Abstract
OBJECTIVE The sole prospective longitudinal study of children with either chronic suppurative lung disease (CSLD) or bronchiectasis published in the current era was limited to a single center. We sought to extend this study by evaluating the longer-term clinical and lung function outcomes and their associated risk factors in Indigenous children of adolescents from Australia, Alaska, and New Zealand who participated in our previous CSLD or bronchiectasis studies during 2004-2010. METHODS Between 2015 and 2018, we evaluated 131 out of 180 (72.8%) children of adolescents from the original studies at a single follow-up visit. We administered standardized questionnaires, reviewed medical records, undertook clinical examinations, performed spirometry, and scored available chest computed tomography scans. RESULTS Participants were seen at a mean age of 12.3 years (standard deviation: 2.6) and a median of 9.0 years (range: 5.0-13.0) after their original recruitment. With increasing age, rates of acute lower respiratory infections (ALRI) declined, while lung function was mostly within population norms (median forced expiry volume in one-second = 90% predicted, interquartile range [IQR]: 81-105; forced vital capacity [FVC] = 98% predicted, IQR: 85-114). However, 43 out of 111 (38.7%) reported chronic cough episodes. Their overall global rating judged by symptoms, including ALRI frequency, examination findings, and spirometry was well (20.3%), stable (43.9%), or improved (35.8%). Multivariable regression identified household tobacco exposure and age at first ALRI-episode as independent risk factors associated with lower FVC% predicted values. CONCLUSION Under our clinical care, the respiratory outcomes in late childhood or early adolescence are encouraging for these patient populations at high-risk of premature mortality. Prospective studies to further inform management throughout the life course into adulthood are now needed.

Abstract
BACKGROUND Chronic inflammation, innate immune activation, T-cell imbalance and endothelial activation have been linked with lung diseases. We sought to determine whether markers of these pathophysiologic pathways were associated with spirometry and chest computed tomography (CT) abnormalities among adolescents living with HIV (ALWH). SETTING Coptic Hope Center for Infectious Diseases in Nairobi, Kenya. METHODS We performed a cross-sectional study of ALWH (10-19 years old). Participants underwent chest CT, spirometry, and venipuncture for serum biomarkers. We also collected demographic, anthropometric, T-cell subset, antiretroviral therapy, and exposure data. We compared characteristics and biomarkers by airflow obstruction [postbronchodilator FEV1/FVC z-score (zFEV1/FVC) < -1.64]. We used multivariable linear regression to determine associations of log10-transformed biomarkers and chest CT abnormalities with lower postbronchodilator zFEV1/FVC (airflow limitation). We performed exploratory principal components analysis on biomarkers, and determined associations of factors with postbronchodilator zFEV1/FVC and chest CT abnormalities. RESULTS Of 47 participants with acceptable quality spirometry, 21 (45%) were female, median age was 13 years and 96% had perinatally-acquired HIV. Median CD4 was 672 cells/µL. Overall, 28% had airflow obstruction and 78% had a chest CT abnormality; airflow obstruction was associated with mosaic attenuation (P = 0.001). Higher endothelial activation (sVCAM-1, sICAM-1), inflammation and innate immune activation (serum amyloid-A, sTREM-1, sCD163), and T-cell imbalance (lower CD4/CD8) markers were associated with airflow limitation. Factors comprising endothelial and innate immune activation were associated with airflow limitation. CONCLUSIONS Endothelial activation, innate immune activation, T-cell imbalance, and chronic inflammation are associated with airflow limitation and obstruction, providing insights into chronic lung disease pathophysiology among ALWH.

Culturally Appropriate Outreach Specialist Respiratory Medical Care Improves the Lung Function of Children in Regional and Remote Queensland. Lung 2020; 198:361-369. [PMID: 32078041 DOI: 10.1007/s00408-020-00332-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 01/20/2020] [Indexed: 12/16/2022]
Abstract
BACKGROUND AND OBJECTIVES Indigenous Respiratory Outreach Care (IROC) is a culturally appropriate specialist respiratory service established to deliver multidisciplinary respiratory care to regional and remote Queensland communities. Our objective was to evaluate the impact of an outreach specialist respiratory service on the spirometry of children attending IROC clinics, particularly Indigenous children with asthma and bronchiectasis. METHODS Retrospective single-arm cohort study of 189 children who performed spirometry at twelve sites across regional and remote Queensland between October 2010 and December 2017. Each child's baseline spirometry was compared to their best spirometry at follow-up visit occurring within (1) 12 months of their most recent visit with at least 12 months of specialist care and; (2) each year of their first 3 years of care. RESULTS Forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) z-scores improved significantly across the whole group from baseline to follow-up (change in z-scores (Δz) of FEV1 = 0.38, 95% CI 0.22, 0.53; ΔzFVC = 0.36, 95% CI 0.21, 0.51). In subgroup analyses, lung function significantly improved in Indigenous children (n = 141, ΔzFEV1 = 0.37, 95% CI 0.17, 0.57; ΔzFVC = 0.36, 95% CI 0.17, 0.55) including those with asthma (n = 117, ΔzFEV1 = 0.41, 95% CI 0.19, 0.64; ΔzFVC = 0.46, 95% CI 0.24, 0.68) and bronchiectasis (n = 38, ΔzFEV1 = 0.33, 95% CI 0.07, 0.59; ΔzFVC = 0.26, 95% CI - 0.03, 0.53). Significant improvements in FEV1 and FVC were observed within the first and second year of follow-up for Indigenous children, but not for non-Indigenous children. CONCLUSION The IROC model of care in regional and remote settings leads to significant lung function improvement in Indigenous children with asthma and bronchiectasis.

Abstract
PURPOSE OF REVIEW a)We conducted a review of the current evidence relating to antibiotic duration in the short and long-term management of non-cystic fibrosis bronchiectasis. RECENT FINDINGS b)In non-cystic fibrosis pulmonary exacerbations, evidence is primarily based on expert consensus and recent guidelines recommend antibiotic durations of approximately 14 days. Chronic antibiotics (oral or inhaled) are recommended in patients with frequent exacerbations or with chronic Pseudomonas aeruginosa airways infection. Macrolides are the best studied therapies for long-term use with evidence for effect limited to a 12 month duration. Encouragingly, there are increased efforts to develop registries and conduct larger population level studies to improve patient care. SUMMARY c)There is a paucity of evidence for optimal antibiotic strategies in exacerbations and chronic maintenance in persons with non-cystic fibrosis bronchiectasis. Rationally designed studies which utilize a registry and population-based approach will be critical to build evidence-based strategies to optimize management of non-cystic fibrosis bronchiectasis.

Abstract
While once thought to be rare, bronchiectasis has been increasing globally over the last 15 years. Bronchiectasis is a major contributor to chronic lung morbidity and mortality but remains a neglected disease in respiratory health globally. Currently, few high-level evidence-based management strategies are available for children with bronchiectasis. Strategies to improve clinical outcomes associated with exacerbations are important. In other respiratory conditions such as asthma and chronic obstructive pulmonary disease, use of personalized written management plans have been shown to improve clinical outcomes. Personalized management plans have also been recommended as part of treatment plans in adults with bronchiectasis. We thus undertook a review of the current literature to determine available evidence, and to establish whether a personalized written bronchiectasis action management plan (BAMP) improves clinical outcomes in children with bronchiectasis. Our search identified 43 articles; 16 duplicates were removed and a further 23 were excluded on titles and abstracts alone. Four full-text articles were reviewed but excluded. In the absence of any published studies, it remains unknown whether the use of BAMP is beneficial for improving clinical outcomes for children with bronchiectasis. These results have highlighted this clinical gap and identified the need for high-quality research to inform practice. Until high-quality evidence is available, clinicians are advised to adhere to current national and/or international guidelines.

Abstract
When children have a wet cough, it suggests the presence of secretions in their airways. This often has an infectious aetiology which is usually a self-limiting viral infection requiring no investigation or treatment. In those with acute wet cough it is, however, important to identify features suggestive of community acquired pneumonia or an inhaled foreign body as these causes require specific management. When there is chronic wet cough, the most common diagnoses are protracted bacterial bronchitis (PBB) and bronchiectasis. The relationship between these two conditions is complex as the development of bronchiectasis manifests as a clinical continuum in which the early features of which are indistinguishable from PBB. It is therefore important to identify PBB and chronic cough endotypes which are associated with an increased risk of bronchiectasis. This article offers a pragmatic approach to the investigation and treatment of children with wet cough. It is hoped this will limit unnecessary investigations whist aiding the prompt diagnosis of conditions needing treatment to reduce symptom burden and prevent further lung damage.

Abstract
INTRODUCTION Alaska Native (AN) children from the Yukon Kuskokwim (YK) Delta region have high rates of chronic suppurative lung disease (CSLD), including bronchiectasis. We characterized the clinical progress of an AN adolescent cohort with CSLD/bronchiectasis, and estimated bronchiectasis prevalence trends in this region. METHODS The original cohort comprised 41 AN children (originally aged 0.5-8 years) with CSLD/bronchiectasis, recruited between 2005 and 2008, with follow-up in 2015-2016. Clinical assessments, lung function, radiography, medical chart review, and spirometry were obtained. We also conducted data queries of bronchiectasis diagnoses in YK individuals born between 1990 and 2010 to estimate prevalence. RESULTS Thirty-four (83%) of the original cohort aged 7.3-17.6 years were reviewed, of whom 14 (41%) had high-resolution computed tomography (HRCT)-confirmed bronchiectasis, eight (24%) had no evidence of bronchiectasis on HRCT scans, while 12 (35%) had not undergone HRCT scans. Annual lower respiratory tract infection (LRTI) frequency decreased with age, although 27 (79%) still had respiratory symptoms, including all with HRCT-confirmed bronchiectasis, who were also more likely than those without confirmed bronchiectasis to have recent wheeze (80 vs 25%, P = 0.005), auscultatory crackles (60 vs 0%, P < 0.001), and lower mean forced expiratory volume in 1-second/forced vital capacity ratio (73 vs 79%, P = 0.03). The bronchiectasis prevalence for YK AN people born during 2000-2009 was 7 per 1000 births, which was lower than previously reported. CONCLUSION Despite reduced LRTI frequency, most AN children with CSLD/bronchiectasis had symptoms/signs of underlying lung disease as they entered adolescence. Close clinical follow-up remains essential for managing these patients as they transition to adulthood.

Abstract
Bronchiectasis is a chronic lung disease associated with structurally abnormal bronchi, clinically manifested by a persistent wet/productive cough, airway infections and recurrent exacerbations. Early identification and treatment of acute exacerbations is an integral part of monitoring and annual review, in both adults and children, to minimize further damage due to infection and inflammation. Common modalities used to monitor disease progression include clinical signs and symptoms, frequency of exacerbations and/or number of hospital admissions, lung function (forced expiratory volume in 1 s (FEV1 )% predicted), imaging (radiological severity of disease) and sputum microbiology (chronic infection with Pseudomonas aeruginosa). There is good evidence that these monitoring tools can be used to accurately assess severity of disease and predict prognosis in terms of mortality and future hospitalization. Other tools that are currently used in research settings such as health-related quality of life (QoL) questionnaires, magnetic resonance imaging and lung clearance index can be burdensome and require additional expertise or resource, which limits their use in clinical practice. Studies have demonstrated that cross-infection, especially with P. aeruginosa between patients with bronchiectasis is possible but infrequent. This should not limit participation of patients in group activities such as pulmonary rehabilitation, and simple infection control measures should be carried out to limit the risk of cross-transmission. A multidisciplinary approach to care which includes respiratory physicians, chest physiotherapists, nurse specialists and other allied health professionals are vital in providing holistic care. Patient education and personalized self-management plans are also important despite limited evidence it improves QoL or frequency of exacerbations.

Abstract
BACKGROUND Chronic respiratory conditions are major causes of mortality and morbidity. Children with chronic health conditions have increased morbidity associated with their physical, emotional, and general well-being. Acute respiratory exacerbations (AREs) are common in children with chronic respiratory disease, often requiring admission to hospital. Reducing the frequency of AREs and recurrent hospitalisations is therefore an important goal in the individual and public health management of chronic respiratory illnesses in children. Discharge planning is used to decide what a person needs for transition from one level of care to another and is usually considered in the context of discharge from hospital to the home. Discharge planning from hospital for ongoing management of an illness has historically been referral to a general practitioner or allied health professional or self management by the individual and their family with limited communication between the hospital and patient once discharged. Effective discharge planning can decrease the risk of recurrent AREs requiring medical care. An individual caseworker-assigned discharge plan may further decrease exacerbations. OBJECTIVES To evaluate the efficacy of individual caseworker-assigned discharge plans, as compared to non-caseworker-assigned plans, in preventing hospitalisation for AREs in children with chronic lung diseases such as asthma and bronchiectasis. SEARCH METHODS We searched the Cochrane Airways Group Specialised Register of Trials, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, trials registries, and reference lists of articles. The latest searches were undertaken in November 2017. SELECTION CRITERIA All randomised controlled trials comparing individual caseworker-assigned discharge planning compared to traditional discharge-planning approaches (including self management), and their effectiveness in reducing the subsequent need for emergency care for AREs (hospital admissions, emergency department visits, and/or unscheduled general practitioner visits) in children hospitalised with an acute exacerbation of chronic respiratory disease. We excluded studies that included children with cystic fibrosis. DATA COLLECTION AND ANALYSIS We used standard Cochrane Review methodological approaches. Relevant studies were independently selected in duplicate. Two review authors independently assessed trial quality and extracted data. We contacted the authors of one study for further information. MAIN RESULTS We included four studies involving a total of 773 randomised participants aged between 14 months and 16 years. All four studies involved children with asthma, with the case-planning undertaken by a trained nurse educator. However, the discharge planning/education differed among the studies. We could include data from only two studies (361 children) in the meta-analysis. Two further studies enrolled children in both inpatient and outpatient settings, and one of these studies also included children with acute wheezing illness (no previous asthma diagnosis); the data specific to this review could not be obtained. For the primary outcome of exacerbations requiring hospitalisation, those in the intervention group were significantly less likely to be rehospitalised (odds ratio (OR) 0.29, 95% confidence interval (CI) 0.16 to 0.50) compared to controls. This equates to 189 (95% CI 124 to 236) fewer admissions per 1000 children. No adverse events were reported in any study. In the context of substantial statistical heterogeneity between the two studies, there were no statistically significant effects on emergency department (OR 0.37, 95% CI 0.04 to 3.05) or general practitioner (OR 0.87, 95% CI 0.22 to 3.44) presentations. There were no data on cost-effectiveness, length of stay of subsequent hospitalisations, or adherence to medications. One study reported quality of life, with no significant differences observed between the intervention and control groups.We considered three of the studies to have an unclear risk of bias, primarily due to inadequate description of the blinding of participants and investigators. The fourth study was assessed as at high risk of bias as a single unblinded investigator was used. Using the GRADE system, we assessed the quality of the evidence as moderate for the outcome of hospitalisation and low for the outcomes of emergency department visits and general practitioner consultations. AUTHORS' CONCLUSIONS Current evidence suggests that individual caseworker-assigned discharge plans, as compared to non-caseworker-assigned plans, may be beneficial in preventing hospital readmissions for acute exacerbations in children with asthma. There was no clear indication that the intervention reduces emergency department and general practitioner attendances for asthma, and there is an absence of data for children with other chronic respiratory conditions. Given the potential benefit and cost savings to the healthcare sector and families if hospitalisations and outpatient attendances can be reduced, there is a need for further randomised controlled trials encompassing different chronic respiratory illnesses, ethnicity, socio-economic settings, and cost-effectiveness, as well as defining the essential components of a complex intervention.

Lancet 2018; 392:1197-1206. [PMID: 30241722 PMCID: PMC7159066 DOI: 10.1016/s0140-6736(18)31723-9] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2018] [Revised: 07/20/2018] [Accepted: 07/20/2018] [Indexed: 12/29/2022]
Abstract
BACKGROUND Although amoxicillin-clavulanate is the recommended first-line empirical oral antibiotic treatment for non-severe exacerbations in children with bronchiectasis, azithromycin is also often prescribed for its convenient once-daily dosing. No randomised controlled trials involving acute exacerbations in children with bronchiectasis have been published to our knowledge. We hypothesised that azithromycin is non-inferior to amoxicillin-clavulanate for resolving exacerbations in children with bronchiectasis. METHODS We did this parallel-group, double-dummy, double-blind, non-inferiority randomised controlled trial in three Australian and one New Zealand hospital between April, 2012, and August, 2016. We enrolled children aged 1-19 years with radiographically proven bronchiectasis unrelated to cystic fibrosis. At the start of an exacerbation, children were randomly assigned to oral suspensions of either amoxicillin-clavulanate (22·5 mg/kg, twice daily) and placebo or azithromycin (5 mg/kg per day) and placebo for 21 days. We used permuted block randomisation (stratified by age, site, and cause) with concealed allocation. The primary outcome was resolution of exacerbation (defined as a return to baseline) by 21 days in the per-protocol population, with a non-inferiority margin of -20%. We assessed several secondary outcomes including duration of exacerbation, time to next exacerbation, laboratory, respiratory, and quality-of-life measurements, and microbiology. This trial was registered with the Australian/New Zealand Registry (ACTRN12612000010897). FINDINGS We screened 604 children and enrolled 236. 179 children had an exacerbation and were assigned to treatment: 97 to amoxicillin-clavulanate, 82 to azithromycin). By day 21, 61 (84%) of 73 exacerbations had resolved in the azithromycin group versus 73 (84%) of 87 in the amoxicillin-clavulanate group. The risk difference showed non-inferiority (-0·3%, 95% CI -11·8 to 11·1). Exacerbations were significantly shorter in the amoxicillin-clavulanate group than in the azithromycin group (median 10 days [IQR 6-15] vs 14 days [8-16]; p=0·014). Adverse events were attributed to the trial medication in 17 (21%) of 82 children in the azithromycin group versus 23 (24%) of 97 in the amoxicillin-clavulanate group (relative risk 0·9, 95% CI 0·5 to 1·5). INTERPRETATION By 21 days of treatment, azithromycin is non-inferior to amoxicillin-clavulanate for resolving exacerbations in children with non-severe bronchiectasis. In some patients, such as those with penicillin hypersensitivity or those likely to have poor adherence, azithromycin provides another option for treating exacerbations, but must be balanced with risk of treatment failure (within a 20% margin), longer exacerbation duration, and the risk of inducing macrolide resistance.

Abstract
Interest in bronchiectasis has increased over the past two decades, as shown by the establishment of disease-specific registries in several countries, the publication of management guidelines and a growing number of clinical trials to address evidence gaps for treatment decisions. This review considers the evidence for defining and treating pulmonary exacerbations, the approaches for eradication of newly identified airway pathogens and the methods to prevent exacerbations through long-term treatments from a pragmatic practice-based perspective. Areas for future studies are also explored. Watch the video abstract.

Abstract
Bronchiectasis is conventionally defined as irreversible dilatation of the bronchial tree. Bronchiectasis unrelated to cystic fibrosis is an increasingly appreciated cause of chronic respiratory-related morbidity worldwide. Few randomised controlled trials provide high-level evidence for management strategies to treat the children affected by bronchiectasis. However, both decades-old and more recent studies using technological advances support the notion that prompt diagnosis and optimal management of paediatric bronchiectasis is particularly important in early childhood. Although considered to be of a non-reversible nature, mild bronchiectasis determined by radiography might be reversible at any age if treated early, and the lung function decline associated with disease progression could then be halted. Although some management strategies are extrapolated from cystic fibrosis or adult-based studies, or both, non-cystic fibrosis paediatric-specific data to help diagnose and manage these children still need to be generated. We present current knowledge and an updated definition of bronchiectasis, and review controversies relating to the management of children with bronchiectasis, including applying the concept of so-called treatable traits.
