Abstract: Invasive fungal infections are a serious consequence of organ transplantation. We observed an increase in Aspergillus infections at our institution among lung transplantation recipients in the year 2000. Records of patients undergoing lung transplantation between 1999 and 2001 were analyzed for evidence of Aspergillus colonization or infection, and potential risk factors for infection were identified. Twenty Aspergillus infections were identified in 103 lung transplant recipients. Thirteen patients had tracheobronchitis, and 7 had invasive pulmonary aspergillosis. Nineteen patients were colonized with Aspergillus. One half of all Aspergillus infections occurred during 2000. There were no differences in demographic or surgical variables, underlying medical illness or postoperative care in association with Aspergillus infection. Factors classically associated with aspergillosis were not found to correlate with an increased risk of infection. Only a specific period of transplantation was significantly associated with Aspergillus infection, suggesting an increased environmental exposure during that period.
