bull E-cigarettes improve smoking cessation but at what cost

bull We need to think about asthma phenotypes (split rather than lump)

bull We should target inhaled steroids in COPD to those who will benefit (high eosinophils)

bull Macrolides beneficial in bronchiectasis but caution with side effects (refer to secondary care)

bull There are new antifibrotics for IPF that halt progression

bull There are mortality benefits of lung cancer screening but we need to adapt to NZ population

Antifibrotics in IPF

Ascend study

bull NEJM 2014 3702093-2101

bull TGF-beta inhibitor

bull N=555 pirfenidone 2403mg (801mg TDS) or placebo per day 52 weeks

bull FVC 50-90 DLCO 30-90

bull Primary FVC fall gt10 or death

bull Secondary 6MWD PFS

Inpulsis study

bull NEJM 2014 3702071-2082

bull Triple kinase inhibitor

(PAGF EGF VEGF)

bull N=1066 nintedanib 150mg bd placebo 32 52 weeks
