Prevalence

52/100000 adults in US (Weycker clin pulm med 2005) Clinical Practice Research database 500/100000 (Quint ERJ 2015)

•Morbidity

321 clinic attendances from 100pts in 6/12 (Kelly et al E J Int

Med 2003)

greater inpatient stay and annual cost/pt than other chronic diseases (CCF, DM) (Weycker clin pulm med 2005)

Morbidity and mortality

•Mortality

UK 12 yr survival 68.3% (Loebinger et al ERJ 2009)

UK 4yr survival 89.8% (Chalmers et al ARJCCM 2014)

Spain 5 yr survival 81.2% (Martinez-Garcia et al ERJ 2014)

Turkey 4 yr survival 58% (Onen et al Respir med 2007)

•Increasing mortality (Roberts et al Respir Med 2010)

Aetiology

Exacerbation definition

A person with bronchiectasis with a deterioration in three or more of the

following key symptoms for at least 48 hours:

1) Cough

2) Sputum volume and / or consistency

3) Sputum purulence

4) Breathlessness and / or exercise tolerance

5) Fatigue and / or malaise

6) Haemoptysis

AND a clinician determines a change in bronchiectasis treatment is

required*

Pulmonary Exacerbation in Adults with Bronchiectasis: A Consensus

Definition from the First World Bronchiectasis Conference

14 days of antibiotics (conditional recommendation, very low quality

of evidence).

Microbiology and Treatment

• Treat underlying cause

• Physiotherapy

• Mucolytics/ HTS

Longer term management

• Treat underlying cause

• Physiotherapy

• Mucolytics/ HTS– Mannitol Ph3 (Bilton 2014 Thorax)

– HTS small studies varied results

(Kellett 2005 – 1 dose, 2011-3/12; Nicholson – 12/12 2012)

Management – airway clearance

• Treat underlying cause

• Physiotherapy

• Mucolytics/ HTS

• Antibiotics

– Long term

– Nebulised

– Oral

– Cyclical IVs

Management – long term antibiotics

Bacterial load (CFU/ml)

141 patients 08-09

≥ 1 exacerbation

500mg MWF 6/12 then 6/12 no treatment

83 patients 08-10

≥ 3 exacerbation

250mg od 12/12, 90/7 run out

117 patients 08-11

≥ 2 exacerbation

400mg bd erythromycin 11/12, 1/12 wash

out

• Colistin - ↓ exacerb in PP (Haworth et al ARJCCM 2014)

• AZLI – no change in QoLB(Barker et al Lancet Resp Med 2014)

• Gentamicin - ↓bacterial, exacerbations,↑QoL(Murray et al 2011 AJRCCM)

Management – long term inhaled

Oral CSx• No evidence

Inhaled CSx • 6RCTs Cochrane • Some ↓ sputum and i0 markers• No good evidence

Statins• ↓ LCQ

NSAIDs• Inhaled indomethacin 25pt • Some ↓ sputum and SOB• No good evidence

Development• CXCR2 antags / N0 elastase inhibs / PDE4 inhibs

Management – alternative anti-inflammatories

• Well as child

• Cough at sputum age 14

• Referred to local hospital at 17 – CT

• LLL and lingula lobectomy

Case 1 RL 20 female

• Well but relapse few months later

• 2/3 pot green sputm

• 4-5 infection/yr

• 2011 repeat CT scan

• Referred to RBH

• IgG <2, A<0.1, M<0.3g/L

• Normal B and T subsets almost absent memory B cells

• Diagnosed with CVID

• Started azithromycin

• IVIG (when trough 7.2 azithro discontinued)

• Case 1 underlying diagnosis

Case 1 RL 20 female

• Asthma as child

• Cough and sputum late 40s

• Bronchiectasis diagnosed 2009

• Idiopathic

• Pseudomonas

• Relatively stable 1-2 infection/yr

Case 2 VR 63 female

• Deterioration last couple of years

• More sputum

• More SOB

• More infections

• Limited effect of antibiotics

• Treated with steroids

• Case 2 additional diagnosis

Case 2 VR 63 female

• Well as child, young adult

• 8 yr history of productive cough

• 6 infections/yr

• Widespread bronchiectasis

• Host defence screen unremarkable

• Some reflux symptoms

• PPI

• Physio review,

Acapella, HTS, positive pressure

• Significant improvement

• 2 infections/yr

• Case 3 - optimisation

Case 3 EM 78 female

• Primary Ciliary Dyskinesia

• Deterioration age 40

• Multiple infections - Pseudomonas

• PSA eradication unsuccessful

• Colomycin nebulised

• Some stabilisation but increased infections

• Increased physiotherapy

• Addition of azithromycin

Case 4 JW 53 female

• More recently repeated need for antibiotics

• Needing several admissions for IV therapy per year

• Anxiety and Depression

• All management optimised

• Cyclical intravenous antibiotics

• Case 4 additional therapies

Case 4 JW 53 female
