Bronchiectasis - Comorbidities • Common among bronchiectasis patients at any stage of the disease • Limited data regarding prevalence and impact on disease outcomes • Single disease approach ineffective • Given ageing population, number of comorbidities likely to increase • Associated increase in healthcare costs Adapted from Do. H document: A framework of principles for system wide action on comorbidity
Bronchiectasis - Derivation cohort • 4 European Centres – Galway (Ireland), n=280 – Dundee (Scotland), n=286 – Leuven (Belgium), n= 190 – Monza (Italy), n=230 • Total study population (n=986)

Asthma phenotypes ØAllergic / Non-allergic (intrinsic) ØInflammatory phenotypes: eosinophilic, neutrophilic, paucigranulocytic ØAsthma in obese adults ØSevere asthma § Adult onset asthma § Adult-onset obese female preponderant asthma § Adult-onset non-atopic, inflammation-predominant phenotype with fixed airflow limitation § Adult-onset mild asthma § Smoking-related asthma Laforest L, et al. Eur Respir J 2006; 27: 42 -50. de Nijs S, Venekamp LN, Bel EH. Eur Respir Rev 2013; 22: 44 -52.
Why is it important to differentiate between asthma phenotypes? • Treatment – Corticosteroids • Disease progress – Fixed airflow obstruction • Genetics of asthma – More accurate disease classification • Aetiology – Causal exposures

Minimal Diagnostic Criteria for ABPA-Central Bronchiectasis • Asthma • Central bronchiectasis • Immediate cutaneous reactivity to Aspergillus species or A. fumigatus • Elevated total serum Ig. E (>417 k. U/L) - 512 k. U/L • Elevated serum Ig. E-A. fumigatus and or Ig. G-A. fumigatus compared to sera from prick positive patients with asthma • Inspisated mucus difficult to remove during bronchoscopy.
Classification of ABPA • ABPA with central bronchiectasis …. . ABPA-CB • ABPA without bronchiectasis…………. ABPA-S • ABPA with “other radiologic findings”. . ABPA-ORF • ABPA is classified into 5 stages for ABPA-CB and 4 stages for ABPA-Seropositive • Patients can change stages over time in either direction except if stage 5 (end stage- fibrocavitary) Ricketti AJ, Greenberger PA et al Arch Int Med 1983; 143: 1553
Treatment Options • Oral Corticosteroids • Anti-fungals • Immunomodulators • TREAT the ASTHMA and CO-MORBIDITIES • CONSIDER ENVIRONMENTAL SOURCES Cochrane Review Wark PAB et al 2004
Prednisone as Monotherapy • 0. 5 mg/kg/each am for 2 weeks then on alterate mornings for 2 months…. Tapered prednisone • Repeat HRCT examination • Repeat total Ig.

Antifungals • Oral (itraconazole, voriconazole, posaconazole) • Adverse effects of itraconazole… – gastrointestinal intolerance, – lfts, – headache, – peripheral neuropathy, – sleep disturbance…. and – inhibition of cyp 3 a 4 dependent hepatic metabolism (increases concentration of prednisolone (not prednisone) and inhaled budesonide and fluticasone causing HPA suppression) Ricketti AJ, Greenberger PA et al Arch Int Med 1983; 143: 1553 ---Cochrane Review Wark PAB et al 2004

The link between fungi and severe asthma: a summary of the evidence ABPA • Asthma (usually severe) • Aspergillus sensitization(Ig. E) • Eosinophilia • • SAFS • Severe Asthma • Fungal sensitisation (Ig. E) • Eosinophilia + / - Aspergillus sensitization (Ig. G) Very high Ig. E level Pulmonary Infiltrates Central bronchiectasis Denning DW et al. Eur Respir J 2006; 27: 615 -626
The Fungal Asthma Sensitization Trial (FAST) study • Atopy to fungal and non-fungal allergens is very common in severe asthma in North West England • SPT and RAST tests can identify fungal sensitisation • At present, it remains necessary to undertake both tests to identify all cases of fungal sensitisation • This may have therapeutic implications (ABPA and SAFS) Denning DW et al Am J Resp Crit Care Med 2008; In press
