Bronchiectasis is gaining recognition as an important chronic lung disease of increasing prevalence

Summary

 

  • Once neglected in research and underappreciated in practice, there is renewed interest in bronchiectasis unrelated to cystic fibrosis.
  • Bronchiectasis is a chronic lung disease characterised by chronic cough, sputum production and recurrent pulmonary exacerbations. It is diagnosed radiologically on high resolution computed tomography chest scan by bronchial dilatation (wider than the accompanying artery).
  • The causes of bronchiectasis are diverse and include previous respiratory tract infections, chronic obstructive pulmonary disease, asthma, immunodeficiency and connective tissue diseases. A large proportion of cases are idiopathic, reflecting our incomplete understanding of disease pathogenesis.
  • Progress in the evidence base is reflected in the 2017 European management guidelines and the 2015 update to the Australian guidelines.
  • Effective airway clearance remains the cornerstone of bronchiectasis management. This should be personalised and reviewed regularly by a respiratory physiotherapist.
  • There is now robust evidence for the long term use of oral macrolide antibiotics in selected patients to reduce exacerbation frequency.
  • The routine use of long term inhaled corticosteroids and/or long-acting bronchodilators should be avoided, unless concomitant chronic obstructive pulmonary disease or asthma exists.
  • The evidence for nebulised agents including hypertonic saline, mannitol and antibiotics is evolving; however, access is challenging outside tertiary clinics, and nebulising equipment is required.
  • Smokers should be supported to quit. All patients should receive influenza and pneumococcal vaccination. Patients with impaired exercise capacity should attend pulmonary rehabilitation.
  • There is an important minority of patients for whom aetiology-specific treatment exists.
  • The prevalence of bronchiectasis is increasing worldwide; however, the burden of disease within Australia is not well defined. To this end, the Australian Bronchiectasis Registry began recruitment in 2016 and is interoperable with the European and United States bronchiectasis registries to enable collaborative research.
  • The recent addition of a bronchiectasis diagnosis-related group to the Australian Refined Diagnostic Related Group classification system will allow definition of the disease burden within the Australian hospital system.

 

Bronchiectasis is a chronic lung disease of diverse aetiology, characterised by a clinical syndrome of chronic cough, sputum production and recurrent pulmonary exacerbations. It is defined radiologically by abnormal bronchial dilatation.1

The reported prevalence of bronchiectasis continues to increase worldwide,2-4 with recent prevalence estimates in the United Kingdom of 566 per 100 000 women and 485 per 100 000 men.3 Females, the elderly,2-4 and Indigenous populations5 are more frequently affected. Notably, Indigenous children in Australia’s Northern Territory have an extremely high disease prevalence of 14.7 per 1000 children;6 however, no large study examining the prevalence of bronchiectasis in Australia has been conducted. The economic burden of bronchiectasis is significant; a recent study conducted in New Zealand reported an annual hospitalisation cost of NZD$5.34 million.7 Quality of life impairment in patients with bronchiectasis is equivalent to the impairment seen in patients with severe chronic obstructive pulmonary disease (COPD).1

Historically, bronchiectasis not due to cystic fibrosis has been neglected in research. This is reflected in the absence of licensed medications for bronchiectasis across Australia, the United States and Europe. Encouragingly, within the past 5 years, research has gained worldwide momentum with the establishment of bronchiectasis registries in Europe and the United States. On a national level, the Australian Bronchiectasis Registry began recruitment in 2016 and a bronchiectasis-specific code was added to the Australian Refined Diagnostic Related Group classification system in 2016.8 Moreover, where there was an absence of high quality evidence to guide bronchiectasis management, in recent years Australian and New Zealand researchers have contributed significantly to the now robust evidence in support of maintenance macrolide antibiotics to reduce pulmonary exacerbations.9,10 Developments in the evidence base are reflected in the 2017 European Respiratory Society bronchiectasis management guidelines1 and in the recently updated Australian guidelines.11

This article reviews the management of bronchiectasis in adults, which is timely given the evolving evidence base and the increasing prevalence and recognition of the disease in clinical practice. Citations were derived from PubMed, Scopus and the Cochrane Library using the terms “non-cystic fibrosis bronchiectasis” or “bronchiectasis” and “treatment” or “management” or “antibiotic” or “inhaled” or “nebul*” or “physiotherapy”, as well as from searching the bibliographies of recent review articles and guidelines.

Pathogenesis and diagnosis

Radiological bronchiectasis is diagnosed using a high resolution computed tomography chest scan when the bronchial diameter exceeds that of the adjacent vessel (broncho-arterial ratio > 1).12 However, the broncho-arterial ratio may be affected by age, and studies indicate that 20–40% of the healthy population over 65 years of age have abnormally high ratios.13,14 Hence, the term “clinically significant bronchiectasis” is used when the radiological diagnosis accompanies the syndrome of cough, sputum, and recurrent respiratory infection. Further recommendations refer to clinically significant bronchiectasis. In addition to airway dilation, a high resolution computed tomography chest scan may show mucus plugging and thickened airway walls, and is important to document disease extent and location, and guide airway clearance manoeuvres.

A diverse range of conditions (Box 1) lead to the common pathological endpoint of bronchiectasis,15 through a cycle of impaired mucus clearance, bacterial colonisation, inflammation, and structural damage occurring in the airways (Box 2).1 On a finer mechanistic level, disease pathogenesis remains incompletely understood; an interplay between genetic susceptibility, immune dysregulation, increased airway neutrophils and neutrophil elastase, and bacterial infection are implicated.16 Idiopathic bronchiectasis is probably relatively rare, but tests of the many subtle abnormalities of immune function are not robust or readily accessible,16 nor is patient recall of past infective illnesses necessarily reliable.

It is important to identify those minority of cases for which specific treatment exists. Box 3 describes the minimum tests recommended for all adult bronchiectasis patients.1,11 Abnormal test results should prompt specialist referral for further investigation and management (Box 4).1,11,12,17,18

General recommendations

The objectives of treatment in bronchiectasis are to improve symptoms and quality of life, reduce exacerbations, and limit disease progression.1 Treatable causes must be identified and specifically addressed (Box 3 and Box 4), however even when a treatable cause is present, the following recommendations apply.

The majority of patients with bronchiectasis produce sputum on a daily basis.19 Augmentation of sputum clearance is critical and should be the cornerstone of daily treatment. Airway clearance makes physiological sense, is safe, inexpensive, and improves quality of life and sputum expectoration.20 All patients should be referred to a specialised respiratory physiotherapist, who can personalise an airway clearance regimen.17 This may include a combination of aerobic exercise, active cycle of breathing, positive expiratory pressure devices and postural drainage.1,11

Smokers should be supported to quit and all patients should receive influenza and pneumococcal vaccination. Patients with impaired exercise capacity should attend pulmonary rehabilitation.11 Surgery is considered rarely for those with localised disease and frequent exacerbations despite optimal management.1 Selected patients with severe disease may be suitable for lung transplant, although there is a paucity of outcome data.12 Excellent resources for patients and clinicians are available from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia.21,22

Many patients may be maintained with an exercise and airway clearance regimen. However, the following medications may be required and prescribed in collaboration with a respiratory physician (Box 5). The indications for specialist review are outlined in Box 6.12

Antibiotics

Patients with bronchiectasis may require antibiotics in four main situations:1,11,23

  • to treat pulmonary exacerbations;

  • to attempt eradication of new Pseudomonas aeruginosa in sputum;

  • as long term treatment to reduce exacerbation frequency and symptoms; or

  • to treat non-tuberculous mycobacterial pulmonary disease.

 

The choice of antibiotic should be guided by the goal of therapy, clinical severity, airway microorganisms and their antibiotic susceptibility (obtained from sputum or bronchoscopy samples), prior antibiotic response, allergies and drug interactions.1,11 High quality evidence to guide antibiotic approach in bronchiectasis is limited. At the time of writing, there are at least four Cochrane Reviews underway investigating aspects of antibiotic use in bronchiectasis.24-27

It should be noted that bronchiectasis patients often have positive sputum culture results.28 With the exception of an exacerbation and/or new isolation of P. aeruginosa, positive cultures alone do not mandate antibiotics.1

Treatment of exacerbations

An exacerbation is defined as deterioration from baseline in three or more of the following symptoms for at least 48 hours, and which a clinician decides requires a change in treatment:29 cough, sputum volume and/or consistency, sputum purulence, breathlessness and/or exercise tolerance, fatigue and/or malaise, and haemoptysis.

The severity of an exacerbation is judged on clinical grounds (eg, significantly deranged vital signs compared with the patient’s baseline would indicate a severe exacerbation).

At the onset of an exacerbation, a sputum sample should be sent for microscopy, culture and sensitivity. If available, previous airway culture and sensitivity results should guide antibiotic choice, otherwise empirical therapy is commenced while culture results are awaited. Box 7 and Box 8 outline a suggested approach to empirical therapy.17,30

Based on low quality evidence and consensus opinion, the recommended duration of antibiotics for an exacerbation is 14 days.1 In practice, antibiotics for 7–14 days are usually prescribed, depending on the clinical situation. Intravenous antibiotics for severe exacerbations are usually continued for at least 5 days, and often followed by oral antibiotics for a total duration of 10–14 days.11

Eradication of Pseudomonas aeruginosa

New isolation of P. aeruginosa in sputum should prompt consideration of antibiotics for eradication,1,11,12,31 as this pathogen confers a worse prognosis. The optimal eradication regime has not been determined, however common practice is to prescribe two weeks of oral ciprofloxacin and then repeat the sputum culture. If the culture remains positive for P. aeruginosa, treatment may be escalated to intravenous or inhaled antibiotics.1,11,12,31 Specialist advice is recommended. There is currently no evidence to support eradication of other organisms.1

Long term antibiotics to reduce exacerbation frequency and symptoms

Under specialist supervision, long term antibiotics (inhaled and/or oral) should be considered in patients who continue to have recurrent or severe exacerbations despite optimal management (good airway clearance regimes, underlying causes treated). Long term macrolide antibiotics currently have the highest level of evidence for reducing exacerbations.1

Long term inhaled antibiotics

Inhaled antibiotics (eg, gentamicin, tobramycin, colistin, ciprofloxacin) may be trialled in selected patients with bacterial colonisation and recurrent exacerbations. Inhaled antibiotics have theoretical advantages in the ability to deliver a high concentration of drug to the airway while markedly reducing systemic absorption and toxicity. There is clear evidence that inhaled antibiotics reduce sputum bacterial load,32-34 and reduced bacterial load has been shown to reduce airway inflammation.35

The use of inhaled antibiotics is challenging however due to the difficulty in accessing these medications for the (non-cystic fibrosis) bronchiectasis population and the incidence of bronchospasm which approximates 10–30% with nebulised aminoglycosides.1,11 Moreover, large trials demonstrating significant improvement in hard clinical endpoints (such as reduced exacerbation frequency) are limited.

Inhaled tobramycin solution was shown in a small phase 2 trial to reduce bacterial density after 28 days treatment, at the expense of increased cough, dyspnoea, wheeze and chest pain.36 A phase 3 trial of tobramycin inhalation solution for bronchiectasis is currently recruiting (NCT02657473), as is a phase 1 trial of dry powder tobramycin (NCT02712983).

A small randomised controlled trial (RCT) of gentamicin nebulised for 12 months demonstrated reduced bacterial density and reduced exacerbations. 22% of participants experienced wheeze, which did not result in withdrawal from the trial, and no ototoxicity or nephrotoxicity was reported.37

A phase 3 trial of colistin nebulised for 6 months showed a trend towards increased time to first exacerbation; this finding was statistically significant when the adherent subgroup was analysed. This trial also demonstrated improvements in quality of life.38 A second phase 3 trial of inhaled colistin is currently recruiting (NCT03093974).

Recent phase 3 trials of aztreonam inhaled for 28 days did not meet their primary endpoint of improved quality of life, and dropouts mainly due to cough and dyspnoea were significantly elevated in the treatment groups.39

Large phase 3 studies of inhaled ciprofloxacin are now complete. RESPIRE 1 and 240,41 (dry powder ciprofloxacin, on-off treatment cycles for 48 weeks, in patients with positive sputum culture at screening for one of seven predefined organisms) and ORBIT 3 and 4 (liposomal ciprofloxacin, on-off treatment cycles for 48 weeks, in patients with chronic P. aeruginosa)42 both used time to first exacerbation and frequency of exacerbations as primary endpoints. RESPIRE 1 and 2 showed trends towards reduced exacerbations, which only met significance in one of two treatment arms (14 days on/off) of the RESPIRE 1 trial. Similarly, ORBIT 4 met the primary endpoints but ORBIT 3 did not. In the ORBIT pooled analysis there was a significant reduction in exacerbation frequency. These large trials showed that inhaled ciprofloxacin is well tolerated (40-42). Promotion of ciprofloxacin resistance with long term use is of concern, particularly as ciprofloxacin is the only oral treatment available for exacerbations in P. aeruginosa colonised patients. The RESPIRE trials reported an increased percentage of sputum pathogens with elevated minimal inhibitory concentrations in the treatment arms compared with placebo arms.40,41 Additional studies will be required to determine ciprofloxacin efficacy and monitor resistance.

The evidence base for long term inhaled antibiotics is emerging. In specialist practice, inhaled antibiotics are prescribed “month on, month off” for carefully chosen patients with recurrent exacerbations, usually with P. aeruginosa colonisation, who tolerate inhaled antibiotics and show a clinical improvement on therapy.31

Long term oral antibiotics

Long term oral antibiotics can also be considered for patients with recurrent exacerbations who are otherwise optimally managed, but should not be prescribed routinely.1,11

Macrolides exert immunomodulatory and antibiotic effects. They have been shown to reduce exacerbation frequency in three well-conducted RCTs of 6–12 months duration. The BAT43 and EMBRACE10 trials used azithromycin, whereas the Australian BLESS trial used erythromycin.9 Reduced exacerbation frequency has been confirmed in meta-analyses which included smaller studies, alternative macrolides, and paediatric data.44-46 Patients with P. aeruginosa colonisation may derive greater benefit;9 however, airway colonisation with P. aeruginosa or other airway pathogens is not a prerequisite for consideration of macrolide treatment.

Patient selection is important. Under specialist supervision, a therapeutic trial (12–24 months) of maintenance macrolide therapy should be considered in patients with recurrent and/or severe exacerbations who are otherwise optimally managed. Prior to macrolide commencement, non-tuberculous mycobacteria (NTM) should be excluded, and a normal QT interval corrected for heart rate on electrocardiogram should be confirmed.1,11

The benefits of macrolides must be weighed against the risk of resistance and side effects. Reduced exacerbation frequency comes at the expense of an increase in macrolide resistance organisms in the oropharynx9 and sputum;43 however, the significance of this is unclear at present. Macrolide monotherapy may induce resistance in NTM, which has implications as macrolides are often used in combination therapy for NTM pulmonary disease. Further, macrolides prolong the QT interval and may increase adverse cardiac events,47 although this was not observed in the three small bronchiectasis RCTs.9,10,43 Macrolide therapy has been associated with hearing decrements in the COPD population; discussion with patients and clinical monitoring is prudent; baseline audiometry could be considered.47

Other long term oral antibiotics (eg, doxycycline or amoxicillin) can be considered in cases of macrolide contraindication or intolerance;1 however, the evidence for alternative antibiotic classes is limited to small historical trials showing reduced sputum purulence and less days off work with oxytetracycline48 and amoxicillin.49,50

Treatment of non-tuberculous mycobacterial pulmonary disease

NTM are ubiquitous environmental organisms that are emerging as increasingly prevalent lung pathogens that can cause or complicate bronchiectasis.23 Progressive inflammatory lung disease (NTM pulmonary disease) must be distinguished from asymptomatic infection or transiently positive sputum cultures. Treatment of NTM pulmonary disease relies on prolonged multidrug regimens with significant side effects and variable success. A decision to treat is not undertaken lightly. Readers are referred to recent NTM pulmonary disease guidelines.23

Mucoactive agents

Nebulised saline and mannitol increase hydration of the airway surface, alter mucus rheology and increase mucociliary clearance.51 They may be trialled in patients who have a substantial sputum burden, difficulty expectorating sputum, poor quality of life and/or frequent exacerbations despite standard airway clearance techniques.1,11

It is unclear whether hypertonic saline is superior to isotonic saline in the non-cystic fibrosis bronchiectasis population. The evidence is limited to two small, randomised trials with conflicting results. In 28 patients undertaking a single-blind crossover study of nebulised 7% saline and 0.9% saline for 3 months, Kellett and colleagues found improvements in lung function, quality of life and health care utilisation when participants were receiving hypertonic saline.52 However, in a 12-month double-blind randomised trial comparing 0.9% and 6% nebulised saline in 40 patients, Nicolson and colleagues found that both groups showed improvements in exacerbations, quality of life, lung function and sputum colonisation compared with baseline.53

The randomised double-blind placebo-controlled trials of inhaled dry powder mannitol failed to meet their primary endpoints. In the first, inhaled mannitol for 3 months in 343 patients failed to show a difference in quality of life, and demonstrated a reduction in 24-hour sputum weight in the placebo group which was associated with increased antibiotic use in this group.54 The subsequent trial in 461 patients over 12 months also failed to meet its primary endpoint of reduced exacerbations, but did show an increased time to first exacerbation.55

Notably, recombinant human deoxyribonuclease is contraindicated in bronchiectasis without cystic fibrosis. The large multicentre randomised double-blind, placebo-controlled trial of deoxyribonuclease in non-cystic fibrosis bronchiectasis found a deleterious effect on lung function and exacerbation frequency.56

Bronchodilators and corticosteroids

Short-acting bronchodilators are recommended before inhalation of mucoactive agents and/or inhaled antibiotics, particularly in those with symptomatic bronchoconstriction, to improve drug tolerability and deposition.1,11

The widespread use of inhaled long-acting bronchodilators (LABD) and corticosteroids in bronchiectasis is driven by extrapolation from the asthma and COPD literature and is not supported by any high level evidence. A Cochrane review of inhaled corticosteroid (ICS) use in bronchiectasis concluded that the evidence did not support routine use of ICS and posed a risk of adverse effects.57 Evidence for long term use of inhaled long-acting β-agonists (LABA) in stable bronchiectasis is limited to one unblinded trial in 40 subjects, comparing combined ICS/LABA (budesonide 640 μg and formoterol 18 μg) with high dose ICS (budesonide 1600 μg).58 Patients who received ICS/LABA had less dyspnoea and more cough-free days after 3 months of treatment than those on ICS alone, with no difference in lung function or exacerbations. However, these findings were potentially the result of a harmful control group; the ICS group predictably had increased adverse events, which were incompletely described. The evidence for long-acting muscarinic receptor antagonists (LAMA) in the bronchiectasis population is extremely limited. A recent RCT of tioptropium versus placebo in 90 stable bronchiectasis patients with airflow obstruction reported very modest improvements in forced expiratory volume in 1 second, but did not report improvements in exacerbation rates, symptoms, or quality of life.59

The routine use of LABD and/or ICS for bronchiectasis is not recommended. However, in the case of concomitant reactive airways disease or COPD, ICS and/or LABD should be prescribed as appropriate for these conditions. Guidelines also make a weak recommendation based on low quality evidence that LABD can be trialled in very breathless bronchiectasis patients on an individual basis.1,11

Conclusion

Bronchiectasis is gaining recognition as an important chronic lung disease of increasing prevalence, which places a significant burden on the health care system and the individual. The goals of therapy are to improve symptoms, reduce exacerbations and limit progression of disease, and the mainstay of treatment is effective airway clearance. The evidence base for the management of this once neglected disease is evolving. The evidence for macrolide antibiotics is robust, and recent European and Australian management guidelines recommend the use of prophylactic macrolides to reduce exacerbation frequency in selected patients with recurrent and/or severe exacerbations. The ecological consequences of long term macrolide use with respect to bacterial resistance have yet to be fully investigated. Data from the Australian Bronchiectasis Registry and the addition of an Australian Refined Diagnostic Related Group bronchiectasis code will provide insight into the burden of disease and patterns of care in Australia.
