Abstract
Cystic Fibrosis (CF) is the most common autosomal recessive genetic multisystemic disease. In Germany, it affects at least 8000 people. The disease is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene leading to dysfunction of CFTR, a transmembrane chloride channel. This defect causes insufficient hydration of the airway epithelial lining fluid which leads to reduction of the mucociliary clearance.Even if highly effective, CFTR modulator therapy has been available for some years and people with CF are getting much older than before, recurrent and chronic infections of the airways as well as pulmonary exacerbations still occur. In adult CF life, Pseudomonas aeruginosa (PA) is the most relevant pathogen in colonisation and chronic infection of the lung, leading to further loss of lung function. There are many possibilities to treat PA-infection.This is a S3-clinical guideline which implements a definition for chronic PA-infection and demonstrates evidence-based diagnostic methods and medical treatment in order to give guidance for individual treatment options.

Long-term Azithromycin in Children With Bronchiectasis Unrelated to Cystic Fibrosis: Treatment Effects Over Time. Chest 2023; 163:52-63. [PMID: 36030839 DOI: 10.1016/j.chest.2022.08.2216] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 07/11/2022] [Accepted: 08/12/2022] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Following evidence from randomized controlled trials, patients with bronchiectasis unrelated to cystic fibrosis receive long-term azithromycin to reduce acute respiratory exacerbations. However, the period when azithromycin is effective and which patients are likely to most benefit remain unknown. RESEARCH QUESTIONS (i) What is the period after its commencement when azithromycin is most effective? and (ii) Which factors may modify azithromycin effects? STUDY DESIGN AND METHODS A secondary analysis was conducted of our previous randomized controlled trial involving 89 indigenous children with bronchiectasis unrelated to cystic fibrosis. Semi-parametric Poisson regression identified the azithromycin efficacy period. Multivariable Poisson regression identified factors that modify azithromycin effect. RESULTS Azithromycin was associated with fewer exacerbations per child-week during weeks 4 through 96, with the most effective period observed between weeks 17 and 62. Eleven factors were associated with different azithromycin effects; four were significant at the P < .05 level. Compared with their counterparts, higher reduction in exacerbations was observed in children with nasopharyngeal carriage of bacterial pathogens (incidence rate ratio [IRR] = 0.81 [95% CI, 0.57-1.14] vs 0.29 [0.20-0.44]; P < .001); New Zealand children (IRR = 0.73 [0.51-1.03] vs 0.39 [0.28-0.55]; P = .012); and those with higher weight-for-height z scores (interaction IRR = 0.82 [0.67-0.99]; P = .044). Compared with their counterparts, lower reduction was observed in those born preterm (IRR = 0.41 [0.30-0.55] vs 0.74 [0.49-1.10]; P = .012). INTERPRETATION Regular azithromycin is best used for at least 17 weeks and up to 62 weeks, as these periods provide maximum benefit for indigenous children with bronchiectasis unrelated to cystic fibrosis. Several factors modified azithromycin benefits; however, these traits need confirmation in larger studies before being adopted into clinical practice.

The effect of N-acetylcysteine in patients with non-cystic fibrosis bronchiectasis (NINCFB): study protocol for a multicentre, double-blind, randomised, placebo-controlled trial. BMC Pulm Med 2022; 22:401. [PMCID: PMC9639270 DOI: 10.1186/s12890-022-02202-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 10/24/2022] [Indexed: 11/09/2022] Open
Abstract
Abstract
Background
N-acetylcysteine (NAC), which is specifically involved in airway mucus clearance and antioxidation, is recommended by the treatment guideline for non-cystic fibrosis bronchiectasis (NCFB). However, there is little clinical evidence of its long-term efficacy concerning quality of life (QoL) and exacerbation in patients with NCFB. In addition, the influences of NAC on airway bacterial colonization, chronic inflammation and oxidative stress in NCFB are also unclear.
Methods
NINCFB is a prospective, multicentre, double-blind, randomised, placebo-controlled trial that will recruit 119 patients with NCFB and randomly divide them into an NAC group (n = 79) and a control group (n = 40). Participants in the NAC group will receive 600 mg oral NAC twice daily for 52 weeks, while patients in the control group will receive 600 mg placebo twice daily for 52 weeks. The information at baseline will be collected once participants are enrolled. The primary endpoints are the changes in St George’s Respiratory Questionnaire scores and the number of exacerbations in 52 weeks. The secondary endpoints are the 16S rRNA of sputum and the levels of inflammatory factors and oxidative stressors in sputum and serum. Other data related to radiography, lung function tests, number of oral and/or intravenous antibiotic therapies and adverse events (AEs) will also be analysed. Further subgroup analysis distinguished by the severity of disease, severity of lung function, airway bacterial colonization and exacerbation frequency will be performed.
Discussion
The objective of this study is to determine the long-term efficacy of NAC on QoL and exacerbation of NCFB and to explore the effectiveness of NAC for antibiosis, anti-inflammation and antioxidation in NCFB. The study results will provide high-quality clinical proof for the revision and optimization of treatment guidelines and for expert consensus on NCFB treatment.
Trial registration
The trial was registered on the Chinese Clinical Trial Register at April 11, 2020 (chictr.org.cn, ChiCTR2000031817).

Safety, Tolerability, and Pharmacokinetic Evaluation of Single and Multiple Doses of the Dipeptidyl Peptidase 1 Inhibitor Brensocatib in Healthy Japanese and White Adults. Clin Pharmacol Drug Dev 2022; 11:832-842. [PMID: 35411669 PMCID: PMC9322451 DOI: 10.1002/cpdd.1094] [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: 10/19/2021] [Accepted: 02/28/2022] [Indexed: 12/02/2022]
Abstract
Brensocatib, an investigational first‐in‐class, small‐molecule, orally bioavailable, selective, and reversible dipeptidyl peptidase 1 inhibitor that blocks activation of neutrophil serine proteases, is currently under clinical development for the treatment of bronchiectasis and other chronic inflammatory diseases. In a 2‐part phase 1 study, the safety, tolerability, and pharmacokinetics of brensocatib were evaluated in healthy Japanese and White adults. In part A, participants received single and multiple once‐daily doses of brensocatib (10, 25, or 40 mg) or placebo after an overnight fast. In part B, participants received a single oral dose of brensocatib 40 mg on days 1 and 8, with or without food in a crossover fashion. Following a single dose and at steady state, brensocatib exposure was dose dependent, with low to moderate interindividual variability; systemic exposure between Japanese and White participants was similar. Elimination half‐life of brensocatib ranged from 22 to 28 hours, resulting in ≈2‐fold accumulation in maximum plasma concentration and area under the plasma concentration–time curve at steady state. In both ethnic groups, the presence of food slightly delayed brensocatib absorption with time to maximum plasma concentration increased by 0.7 to 1.7 hours, but it had no significant effect on brensocatib exposure (maximum plasma concentration and area under the plasma concentration–time curve). Brensocatib was well tolerated in Japanese and White participants. The most frequently reported treatment‐emergent adverse events were headache and skin exfoliation. No clinically significant vital signs, laboratory abnormalities, or evidence of renal toxicity were observed. The results from this study demonstrate that brensocatib can be administered with or without food and that dose adjustment is unnecessary for Japanese patients when receiving brensocatib treatment.

EVALUATING THE EFFICACY OF HUMAN BRONCHIECTASISBASED ANTIBIOTIC THERAPY IN THE TREATMENT OF ORANGUTAN RESPIRATORY DISEASE SYNDROME. J Zoo Wildl Med 2022; 52:1205-1216.

Abstract
Unique among apes, orangutans (Pongo spp.) develop a chronic respiratory disease called orangutan respiratory disease syndrome (ORDS). The authors define ORDS as intermittent bacterial infection and chronic inflammation of any region or combination of regions of the respiratory tract, including the sinuses, air sacs, cranial bones, airways, and lung parenchyma. Infection in any of these areas can present acutely but then becomes recurrent, chronic, progressive, and ultimately fatal. The closest model to this disease is cystic fibrosis (CF) in people. We hypothesized that use of a 4-8-wk course of combined oral antibiotics used in the treatment of bronchiectasis in CF patients would lead to prolonged symptomatic and computed tomography (CT) scan improvement in orangutans experiencing early signs of ORDS. Nine adult Bornean orangutans (Pongo pygmaeus, eight males, one female, 18-29 yr of age) diagnosed with early ORDS-like respiratory disease underwent CT scan before initiation of treatment. Each animal received a combined course of azithromycin (400 mg 3/wk, mean 7 mg/kg) and levofloxacin (500 mg PO q24h, mean 8.75 mg/kg) for a period of 4-8 wk. CT scan was repeated 6-14 mon after completion of antibiotic treatment. Pretreatment CT showed that six of nine animals had lower respiratory pathology (airway disease, pneumonia, or both). All six orangutans had concurrent sinusitis, mastoiditis, airsacculitis, or a combination of these conditions. Upper respiratory disease alone was observed in three animals. CT showed improvement or resolution in four of five sinusitis cases, improvement in one of two instances of mastoiditis, resolution in five of six instances of airsacculitis, improvement or resolution in six of six instance of lower airway disease (P = 0.03, 95% CI 0.54-1.0], and resolution in five of five cases of pneumonia. Resolution of pretreatment clinical signs was observed in all nine animals. Two developed signs not present at pretreatment. These results show that combination antibiotic therapy with azithromycin and levofloxacin provides improvement in clinical signs and CT evidence of ORDS-related pathology, resulting in symptom-free status in some animals for up to 33 mon.

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
Since its emergence in Wuhan, China, covid-19 has spread and had a profound effect on the lives and health of people around the globe. As of 4 July 2021, more than 183 million confirmed cases of covid-19 had been recorded worldwide, and 3.97 million deaths. Recent evidence has shown that a range of persistent symptoms can remain long after the acute SARS-CoV-2 infection, and this condition is now coined long covid by recognized research institutes. Studies have shown that long covid can affect the whole spectrum of people with covid-19, from those with very mild acute disease to the most severe forms. Like acute covid-19, long covid can involve multiple organs and can affect many systems including, but not limited to, the respiratory, cardiovascular, neurological, gastrointestinal, and musculoskeletal systems. The symptoms of long covid include fatigue, dyspnea, cardiac abnormalities, cognitive impairment, sleep disturbances, symptoms of post-traumatic stress disorder, muscle pain, concentration problems, and headache. This review summarizes studies of the long term effects of covid-19 in hospitalized and non-hospitalized patients and describes the persistent symptoms they endure. Risk factors for acute covid-19 and long covid and possible therapeutic options are also discussed.

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

Abstract
Pseudomonas aeruginosa (PA) in patients with bronchiectasis (BE) is associated with a poor outcome and quality of life, and its presence is considered a marker of disease severity. This opportunistic pathogen is known for its ability to produce biofilms on biotic or abiotic surfaces and to survive environmental stress exerted by antimicrobials, inflammation, and nutrient or oxygen depletion. The presence of PA biofilms has been linked to chronic respiratory infection in cystic fibrosis but not in BE. There is considerable inconsistency in the reported infection/eradication rates of PA and chronic PA. In addition, inadequate antimicrobial treatment may potentiate the progression from intermittent to chronic infection and also the emergence of antibiotic resistance. A better comprehension of the pathophysiology of PA infections and its implications for BE is urgently needed. This can drive improvements in diagnostic accuracy, can move us toward a new consensus definition of chronic infection, can better define the follow-up of patients at risk of PA, and can achieve more successful eradication rates. In addition, the new technological advances regarding molecular diagnostics, -omics, and biomarkers require us to reconsider our traditional concepts.

Exacerbations and Changes in Physical Activity and Sedentary Behaviour in Patients with Bronchiectasis after 1 Year. J Clin Med 2021; 10:jcm10061190. [PMID: 33809173 PMCID: PMC7998500 DOI: 10.3390/jcm10061190] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/03/2021] [Accepted: 03/10/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Low physical activity and high sedentary behaviour in patients with bronchiectasis are associated with hospitalisation over one year. However, the factors associated with longitudinal changes in physical activity and sedentary behaviour have not been explored. We aimed to identify clinical and sociodemographic characteristics related to a change in physical activity and sedentary behaviour in patients with bronchiectasis after one year. Methods: This was a prospective observational study during which physical activity measurements were recorded using a SenseWear Armband for one week at baseline and at one year. At each assessment point, patients were classified as active or inactive (measured as steps per day) and as sedentary or not sedentary (measured as sedentary time). Results: 53 patients with bronchiectasis were analysed, and after one year, 18 (34%) had worse activity and sedentary levels. Specifically, 10 patients became inactive and sedentary. Multivariable analysis showed that the number of exacerbations during the follow-up period was the only outcome independently associated with change to higher inactivity and sedentary behaviour (odds ratio (OR), 2.19; 95% CI, 1.12 to 4.28). Conclusions: The number of exacerbations in patients with bronchiectasis was associated with changes in physical activity and sedentary behaviour. Exacerbation prevention may appear as a key factor in relation to physical activity and sedentary behaviour in patients with bronchiectasis.

Network Pharmacology Analysis of the Therapeutic Mechanisms Underlying Beimu-Gualou Formula Activity against Bronchiectasis with In Silico Molecular Docking Validation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:3656272. [PMID: 33488758 PMCID: PMC7803403 DOI: 10.1155/2021/3656272] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 12/14/2020] [Accepted: 12/19/2020] [Indexed: 01/05/2023]
Abstract
Background The classical Chinese herbal prescription Beimu-Gualou formula (BMGLF) has been diffusely applied to the treatment of respiratory diseases, including bronchiectasis. Although concerning bronchiectasis the effects and mechanisms of action of the BMGLF constituents have been partially elucidated, it remains to be determined how the formula in its entirety exerts therapeutic effects. Methods In this study, the multitarget mechanisms of BMGLF against bronchiectasis were predicted with network pharmacology analysis. Using prepared data, a drug-target interaction network was established and subsequently the core therapeutic targets of BMGLF were identified. Furthermore, the biological function and pathway enrichment of potential targets were analyzed to evaluate the therapeutic effects and pivotal signaling pathways of BMGLF. Finally, virtual molecular docking was performed to assess the affinities of compounds for the candidate targets. Results The therapeutic action of BMGLF against bronchiectasis involves 18 core target proteins, including the aforementioned candidates (i.e., ALB, ICAM1, IL10, and MAPK1), which are assumed to be related to biological processes such as drug response, cellular response to lipopolysaccharide, immune response, and positive regulation of NF-κB activity in bronchiectasis. Among the top 20 signaling pathways identified, mechanisms of action appear to be primarily related to Chagas disease, allograft rejection, hepatitis B, and inflammatory bowel disease. Conclusion In summary, using a network pharmacology approach, we initially predicted the complex regulatory profile of BMGLF against bronchiectasis in which multilink suppression of immune/inflammatory responses plays an essential role. These results may provide a basis for novel pharmacotherapeutic approaches for bronchiectasis.

Front Pharmacol 2019; 10:1409. [PMID: 31849665 PMCID: PMC6895570 DOI: 10.3389/fphar.2019.01409] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 11/05/2019] [Indexed: 01/14/2023] Open
Abstract
Background: To determine the effects of bronchodilator, steroid, and anti-arrhythmia drug use on the risk of heart disease/stroke (HDS) in patients with bronchiectasis–chronic obstructive pulmonary disease overlap syndrome (BCOS). Methods: We retrospectively enrolled patients with BCOS (BCOS cohort, n = 1,493) and patients without bronchiectasis and chronic obstructive pulmonary disease (COPD) (non-BCOS cohort, n = 5,972). The cumulative incidence of HDS was analyzed through Cox proportional regression. We calculated adjusted hazard ratios (aHRs) and their 95% confidence intervals (CIs) for HDS after adjustments for sex, age, comorbidities, long-acting β2-agonist or long-acting muscarinic antagonist (LABAs/LAMAs) use, short-acting β2-agonist or short-acting muscarinic antagonist (SABAs/SAMAs) use, oral steroid (OSs) or inhaled corticosteroid steroid (ICSs) use, and anti-arrhythmia drugs use. Results: The aHR (95% CI) for HDS was 1.08 (0.28–4.06) for patients using LAMAs compared with those not using drugs. Regarding drug use days, the aHRs (95% CIs) were 32.2 (1.79–773.0), 1.85 (1.01–3.39), and 31.1 (3.25–297.80) for those with recent SABAs use, past ICSs use, and past anti-arrythmia drugs use, respectively. Regarding cumulative drug dose, the aHRs (95% CIs) were 2.12 (1.46–3.10), 3.48 (1.13–10.6), 3.19 (2.04–4.99), 28.1 (1.42–555.7), 2.09 (1.32–3.29), 2.28 (1.53–3.40), and 1.93 (1.36–2.74) for those with a low dose of SABAs, medium dose of SABAs, low dose of SAMAs, low dose of ICSs, medium dose of ICSs, low dose of OSs, and medium dose of OSs, respectively. Conclusions: Compared with patients without bronchiectasis and COPD, BCOS patients with recent SABAs, past ICSs, and past anti-arrhythmia drugs use; a low or medium SABAs ICSs, and OSs dose; and a low SAMAs dose had a higher risk of HDS. LAMAs were not associated with HDS.

Abstract
BACKGROUND Current guidelines for the management of bronchiectasis (BE) highlight the lack of evidence to recommend mucoactive agents, such as hypertonic saline (HTS) and carbocisteine, to aid sputum removal as part of standard care. We hypothesise that mucoactive agents (HTS or carbocisteine, or a combination) are effective in reducing exacerbations over a 52-week period, compared to usual care. METHODS This is a 52-week, 2 × 2 factorial, randomized, open-label trial to determine the clinical effectiveness and cost effectiveness of HTS 6% and carbocisteine for airway clearance versus usual care - the Clinical and cost-effectiveness of hypertonic saline (HTS 6%) and carbocisteine for airway clearance versus usual care (CLEAR) trial. Patients will be randomised to (1) standard care and twice-daily nebulised HTS (6%), (2) standard care and carbocisteine (750 mg three times per day until visit 3, reducing to 750 mg twice per day), (3) standard care and combination of twice-daily nebulised HTS and carbocisteine, or (4) standard care. The primary outcome is the mean number of exacerbations over 52 weeks. Key inclusion criteria are as follows: adults with a diagnosis of BE on computed tomography, BE as the primary respiratory diagnosis, and two or more pulmonary exacerbations in the last year requiring antibiotics and production of daily sputum. DISCUSSION This trial's pragmatic research design avoids the significant costs associated with double-blind trials whilst optimising rigour in other areas of trial delivery. The CLEAR trial will provide evidence as to whether HTS, carbocisteine or both are effective and cost effective for patients with BE.

Clinical Factors Associated with a Shorter or Longer Course of Antibiotic Treatment in Patients with Exacerbations of Bronchiectasis: A Prospective Cohort Study. J Clin Med 2019; 8:jcm8111950. [PMID: 31726739 PMCID: PMC6912316 DOI: 10.3390/jcm8111950] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 11/07/2019] [Accepted: 11/11/2019] [Indexed: 12/19/2022] Open
Abstract
Background: Bronchiectasis exacerbations are often treated with prolonged antibiotic use, even though there is limited evidence for this approach. We therefore aimed to investigate the baseline clinical and microbiological findings associated with long courses of antibiotic treatment in exacerbated bronchiectasis patients. Methods: This was a bi-centric prospective observational study of bronchiectasis exacerbated adults. We compared groups receiving short (≤14 days) and long (15–21 days) courses of antibiotic treatment. Results: We enrolled 191 patients (mean age 72 (63, 79) years; 108 (56.5%) females), of whom 132 (69%) and 59 (31%) received short and long courses of antibiotics, respectively. Multivariable logistic regression of the baseline variables showed that long-term oxygen therapy (LTOT), moderate–severe exacerbations, and microbiological isolation of Pseudomonas aeruginosa were associated with long courses of antibiotic therapy. When we excluded patients with a diagnosis of community-acquired pneumonia (n = 49), in the model we found that an etiology of P. aeruginosa remained as factor associated with longer antibiotic treatment, with a moderate and a severe FACED score and the presence of arrhythmia as comorbidity at baseline. Conclusions: Decisions about the duration of antibiotic therapy should be guided by clinical and microbiological assessments of patients with infective exacerbations.

Management of Australian Adults with Bronchiectasis in Tertiary Care: Evidence-Based or Access-Driven? Lung 2019; 197:803-810. [PMID: 31691027 DOI: 10.1007/s00408-019-00280-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2019] [Accepted: 10/15/2019] [Indexed: 02/08/2023]
Abstract
PURPOSE Australian data regarding the management of patients with bronchiectasis is scarce. We sought to compare the management of adults with bronchiectasis attending tertiary Australian centres with recent national and international guidelines. METHODS The Australian Bronchiectasis Registry is a centralised database of patients with radiologically confirmed bronchiectasis unrelated to cystic fibrosis recruited from 14 tertiary Australian hospitals. We excluded children (<18 years) and those with incomplete data, leaving 589 adults for cross-sectional analyses. We compared the proportion of patients receiving certain therapies, as compared to the proportion eligible for those treatments according to the current guidelines and baseline clinical information available from the registry. RESULTS Pulmonary rehabilitation was attended by 22%, although it was indicated in 67% of the cohort. Airway clearance was undertaken in 52% of patients, although 71% reported chronic productive cough. Sputum bacterial culture results were available for 59%, and mycobacterial culture results were available for 29% of the cohort. Inhaled antibiotics were used in half of potentially eligible patients. Despite guideline recommendations against routine use, inhaled corticosteroids were used in 48% of patients. Long-term macrolides were used in 28% of participants. CONCLUSIONS Discrepancies exist between guideline recommendations and real-world treatment of bronchiectasis in Australia, even in tertiary centres. These findings suggest the need for increased patient referral to pulmonary rehabilitation, increased attention to airway clearance, increased collection of sputum samples (especially for mycobacterial culture) and rationalisation of inhaled corticosteroid use. These findings encourage a review of treatment access and will inform ongoing education to promote evidence-based care for people living with bronchiectasis.

THE LANCET RESPIRATORY MEDICINE 2019; 7:791-801. [PMID: 31427252 PMCID: PMC7172658 DOI: 10.1016/s2213-2600(19)30254-1] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Revised: 05/29/2019] [Accepted: 06/06/2019] [Indexed: 12/13/2022]
Abstract
Background Bronchiectasis guidelines recommend antibiotics for the treatment of acute respiratory exacerbations, but randomised placebo-controlled trials in children are lacking. We hypothesised that oral amoxicillin–clavulanate and azithromycin would each be superior to placebo in achieving symptom resolution of non-severe exacerbations in children by day 14 of treatment. Methods In this multicentre, three-arm, parallel, double-dummy, double-blind, randomised placebo-controlled trial at four paediatric centres in Australia and New Zealand, we enrolled children aged 1–18 years with CT-confirmed bronchiectasis unrelated to cystic fibrosis, who were under the care of a respiratory physician and who had had at least two respiratory exacerbations in the 18 months before study entry. Participants were allocated (1:1:1) at exacerbation onset to receive oral suspensions of amoxicillin–clavulanate (45 mg/kg per day) plus placebo azithromycin, azithromycin (5 mg/kg per day) plus placebo amoxicillin–clavulanate, or both placebos for 14 days. An independent statistician prepared a computer-generated, permuted-block (size 2–8) randomisation sequence, stratified by centre, age, and cause. Participants, caregivers, study coordinators, and investigators were masked to treatment assignment until data analysis was completed. The primary outcome was the proportion of children with exacerbation resolution by day 14 in the intention-to-treat population. Treatment groups were compared using generalised linear models. Statistical significance was set at p<0·0245 to account for multiple comparisons. This trial is registered with the Australian New Zealand Clinical Trials Registry (ACTRN12612000011886) and is completed. Findings Between April 17, 2012, and March 1, 2017, 604 children were screened and 252 were enrolled. Between July 31, 2012, and June 26, 2017, 197 children were allocated at the start of an exacerbation (63 to the amoxicillin–clavulanate group, 67 to the azithromycin group, and 67 to the placebo group). Respiratory viruses were identified in 82 (53%) of 154 children with available nasal swabs on day 1 of treatment. Primary outcome data were available for 196 (99%) children (one child with missing data [placebo group] was recorded as non-resolved according to criteria defined a priori). By day 14, exacerbations had resolved in 41 (65%) children in the amoxicillin–clavulanate group, 41 (61%) in the azithromycin group, and 29 (43%) in the placebo group. Compared with placebo, relative risk for resolution by day 14 was 1·50 (95% CI 1·08–2·09, p=0·015; number-needed-to-treat [NNT] 5 [95% CI 3–20]) in the amoxicillin–clavulanate group and 1·41 (1·01–1·97, p=0·042; NNT 6 [3–79]) in the azithromycin group. Adverse events were recorded in 19 (30%) children in the amoxicillin–clavulanate group, 20 (30%) in the azithromycin group, and 14 (21%) in the placebo group, but no events were severe or life-threatening. Interpretation Amoxicillin–clavulanate treatment is beneficial in terms of resolution of non-severe exacerbations of bronchiectasis in children, and should remain the first-line oral antibiotic in this setting.

Australian adults with bronchiectasis: The first report from the Australian Bronchiectasis Registry. Respir Med 2019; 155:97-103. [PMID: 31326739 DOI: 10.1016/j.rmed.2019.07.016] [Citation(s) in RCA: 38] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/18/2019] [Revised: 07/02/2019] [Accepted: 07/15/2019] [Indexed: 12/19/2022]
Abstract
BACKGROUND /objective: There are no large, multi-centre studies of Australians with bronchiectasis. The Australian Bronchiectasis Registry (ABR) was established in 2015 to create a longitudinal research platform. We aimed to describe the baseline characteristics of adult ABR participants and assess the impact of disease severity and exacerbation phenotype on quality of life (QoL). METHODS The ABR is a centralised database of patients with radiologically confirmed bronchiectasis unrelated to cystic fibrosis. We analysed the baseline data of adult patients (≥18 years). RESULTS From March 2016-August 2018, 799 adults were enrolled from 14 Australian sites. Baseline data were available for 589 adults predominantly from six tertiary centres (420 female, median age 71 years (interquartile range 64-77), 14% with chronic Pseudomonas aeruginosa infection). Most patients had moderate or severe disease based on the Bronchiectasis Severity Index (BSI) (84%) and FACED (59%) composite scores. Using Global Lung function Initiative-2012 reference equations, the majority of patients (48%) had normal spirometry; only 34% had airflow obstruction (FEV1/FVC < LLN). Disease severity scores (BSI and FACED) were negatively correlated with QoL-Bronchiectasis domain scores (rs between -0.09 and -0.58). The frequent exacerbator phenotype (≥3 in the preceding year) was identified in 23%; this group had lower scores in all QoL-B domains (p ≤ 0.001) and more hospitalisations (p < 0.001) than those with <3 exacerbations. CONCLUSIONS The largest cohort of Australian adults with bronchiectasis has been described. Using contemporary criteria, most patients with bronchiectasis did not have airflow obstruction. The frequent exacerbation trait connotes poorer QoL and greater health-care utilisation.
