Chronic Pulmonary Aspergillosis
RUL cavity - Patient RW
December 1991
Thought to have lung carcinoma as
smoker
RU lobectomy
2-cm cavity with necrotic contents
associated with local bronchiectasis and
thickening of the pleura.
Surrounding lung showed severe
emphysema with fibrosis. The cavity
was in an area of cystic bronchiectasis.
The cavity contained a fungus ball
without invasion or tissue eosinophilia.
One necrotizing granuloma seen. AFB
stains negative and cultures negative
for TB: Fungal cultures not done.
He was thought cured because the
whole lesion was resected.

CPA and surgery
• Single aspergillomas are amenable to surgery
• CCPA (complex aspergilloma) has a high complication
rate with surgery (mortality >5%, morbidity >30%)
• Haemoptysis, chronic ill-health and contraindications or
intolerance of azole antifungal therapy reasonable
indications
• Azole resistance also a new indication

Treatment
Antifungal therapy
IDSA guidelines. Walsh et al. Clin Infect Dis 2008;46:327
CPA and haemoptysis
• Minor haemoptysis common
• Manageable with tranexamic acid
orally
• Bronchial embolisation a good
option, if vessel can be embolised
& patient can lie flat for 2-3
hours

CPA treatment - principles
• Important defects in innate immunity so long term (i.e.
life-long) antifungal treatment, if possible
• Some patients appear not to progress, but should to be
kept under observation, as progression may be
subclinical
• Minimise other causes of lung infection with
immunisation and antibiotics
• Itraconazole, voriconazole and posaconazole all
effective, but adverse events
• Amphotericin B useful for oral azole therapy and
failure
• Gamma IFN helpful in some cases
• Monitor for azole resistance

ABPA/SAFS treatment - principles
• Variable natural history, so individualise therapy
• Short term goal is minimise symptoms and impact of
activities of life
• Long term goal is to prevent or minimise complications
of bronchiectasis and chronic pulmonary aspergillosis
and fibrosis
• Concurrent or additional bacterial and/or viral
infections common, especially if bronchiectasis present.
• Inhaled and/or oral corticosteroids important for
exacerbations, but should be minimised between
episodes
• Azithromycin and hypertonic saline often helpful
• Antifungal therapy response may be dramatic, but some
issues with therapy
