Title: Epidemiology of ABPA | Jindal Chest Clinic


1
Epidemiology of ABPA
2
ABPA prevalence
  • Prevalence of ABPA quoted as 1-2 in asthma and
    2-15 in cystic fibrosis in most reviews
  • Two unpublished questionnaire-based surveys and
    one published study
  • Ireland study - catchment area of 0.5 million -
    14 patients with ABPM in 1390 referrals - period
    prevalence of 1 Donnelly et al. Ir J Med Sci
    1991 160 288290

3
ABPA prevalence
  • Two questionnaire based studies
  • Orange County, California - 2.4 million people -
    143 cases of ABPA
  • AAAAI survey - survey among members of the
    academy - 703 ABPA Novey et al. Immunol Allergy
    Clin North Am 1998 18 641653
  • Both of the above surveys in the US - total ABPA
    in 1991 to be around 11,000 (total population -
    260 million) - 1 of the estimated 12 million
    asthma patients in the US

    patients
  • ABPA - 155 patients (20.6)
  • Serologic ABPA 37 (23.9) patients
  • ABPA with CB 118 (76.1) patients
