Clinical significance of extra-pulmonary involvement of invasive aspergillosis: a retrospective autopsy-based study of 107 patients.

Disseminated aspergillus infection has a poor prognosis, but few reports have been published on extra-pulmonary involvement in aspergillosis. We reviewed 107 autopsy records of patients with invasive aspergillosis. Fifty-five patients had extra-pulmonary aspergillosis. Organs involved included heart, kidney, central nervous system, gastrointestinal tract, spleen, liver, thyroid gland and pancreas. Extra-pulmonary aspergillosis produces different manifestations according to involved organs. Risk factors associated with dissemination included cytotoxic chemotherapy within a month of death (P=0.0087). Lack of response to empiric or preemptive treatment of amphotericin B predicted IA dissemination (P=0.0328). To improve prognosis of IA, it is important to recognize clinical features of extra-pulmonary aspergillosis and to institute the aggressive anti-fungal treatment.
