Aspergillosis is an infection or an allergic response
caused by a fungus of the Aspergillus type. It may play a role in allergy, but
is best known for causing serious pulmonary infections in immunocompromised
patients
It causes illness in three ways:
as an allergic reaction in people with asthma
as a colonization and growth in a lung injury (such as from
tuberculosis or lung abscess)
as an invasive systemic infection with pneumonia, nasal
necrosis or aural inflammation and necrosis that is spread to other parts of the
body by the bloodstream (pulmonary aspergillosis - invasive type).

Symptoms involving specific organs
Brain: meningitis
Eye: blindness or visual
impairment
Sinuses: sinusitis
Heart: endocarditis
Signs and tests
Abnormal chest X-ray or CT scan
Sputum stain and culture showing Aspergillus
Tissue biopsy (see bronchoscopy with transtracheal biopsy)
for aspergillosis
Aspergillus antigen skin test
Aspergillosis precipitin antibody or galactomannan
positivity
Elevated serum total IgE (immunoglobulin)
Peripheral eosinophilia with allergic disease
Treatment
intravenous amphotericin B, an antifungal medication.
Itraconazole can also be used, or its newer counterpart
voriconazole.
Caspofungin may be tried when other drug therapy has
failed.
Endocarditis caused by Aspergillus is treated by surgical
removal of the infected heart valves and long-term amphotericin B therapy.
Allergic aspergillosis is treated with oral prednisone.
