This is the first report of Aureobasidium (A.) pullulans as an, opport
unistic pulmonary infection in a liver transplant recipient. A 46-year
-old caucasian man. had an orthotopic liver transplant in 1988. His li
ver disease was primary sclerosing cholangitis. He required 2 subseque
nt liver re-transplants for primary graft non-function and acute rejec
tion. The patient had been living in the California desert for two mon
ths prior to admission and presented with ventilator-dependent acute r
espiratory failure and hemodialysis-dependent acute renal failure. Ima
ging studies revealed severe bilateral infiltrates. His initial bronch
oalveolar Lavage (BAL) and brushings gl ew A. pullulans. Pancultures,
including sputum and throat cultures, were negative for bacterial or o
ther fungal organisms. The patient responded to pulmonary support and
aggressive systemic antifungal agents while being maintained on cyclos
porine and prednisone for immunosuppression, He was discharged to a sh
illed nursing facility 37 days after hospitalisation. Delay in dischar
ge was primarily due to severe malnutrition and renal impairment. Oppo
rtunistic fungal infections continue to be a major problem in. immunos
uppressed patients including liver transplant recipients. Here we repo
rt a pulmonary infection with. Coccidioides (C.) immitis and superinfe
ction with A. pullulans Opportunistic infections such as A. pullulans
can be treated successfully with systemic fluconazole when, amphoteric
in B is not well tolerated.
