Multi-country estimate of different manifestations of aspergillosis in cystic fibrosis.

Aspergillus spp. can lead to allergic bronchopulmonary aspergillosis (ABPA), Aspergillus sensitisation and Aspergillus bronchitis in CF. The relative frequencies of these entities have recently been ascertained in a large UK adult CF cohort. We have used this data to estimate the burden of aspergill...

National and international CF registry data was accessed and assessed for completeness and age distribution. Published proportions of ABPA (17.7%), Aspergillus sensitisation (14.6%) and Aspergillus bronchitis (30%) in CF were applied to those >18 years and compared with notified ABPA cases.

The ABPA diagnosis rate compared with estimated rates varies by country from 101% (France) to 14.5% (Greece), although genetic variation could account for genuine differences compared with the UK. Aspergillus bronchitis is not currently recognised or recorded in CF registries but there are an anticipated 10,988 adult cases. Aspergillus sensitisation, associated with increased bronchiectasis and reduced FEV1, affects an anticipated 5,506 patients without ABPA or Aspergillus bronchitis. Together ABPA and Aspergillus bronchitis are estimated to affect 17,989 adults, 47.7% of the adult CF population. ABPA also occurs in children and teenagers and 984 cases were documented in registries. Diagnosed ABPA rates by age were available for the ECFS registry, USA, UK, Ireland, Belgium and Netherlands.
