Aspergillosis in liver transplant recipients: successful treatment and improved survival using a multistep approach.

摘要

BACKGROUND: Invasive aspergillosis is a life-threatening complication in liver transplant recipients, with a reported mortality rate of more than 90%. Treatment is difficult, and no single agent is uniformly effective in treating this patient population. METHODS: We retrospectively reviewed all fungal cultures from 200 liver transplant patients between 1996 and 1999 at a single tertiary referral center. RESULTS: A diagnosis of aspergillosis was made in 6 patients. Five patients had pulmonary involvement; 1 presented with an inguinal mass. Time from transplant to infection ranged from 1 week to 34 months. Treatment included surgical intervention and medical treatment. All patients infected with Aspergillus fumigatus were treated with a sequential protocol of lipid complex amphotericin followed by itraconazole. The major side effect of treatment was worsening renal function. One patient died of intracranial hemorrhage during treatment. CONCLUSION: Successful treatment of aspergillosis in liver transplant recipients should include early diagnosis, sequential medical treatment with lipid amphotericin B and itraconazole, and surgical intervention for invasive disease.
