Nebulized amphotericin B deoxycholate (n-ABD) is used to prevent Aspergillus infection in lung transplantation. Nebulized liposomal amphotericin B (n-LAB) is another option; however, no clinical data are available on the results of n-LAB for this purpose. In an observational study performed in 2 centers to assess the feasibility, tolerability, and outcomes of n-LAB prophylaxis, 104 consecutive patients undergoing prophylaxis with n-LAB were compared with 49 historical controls who received n-ABD. Patient follow-up lasted 12 months. The n-LAB prophylaxis regimen was 25 mg thrice weekly starting on the first post-operative day and continuing to 60 days, 25 mg once weekly from 60 to 180 days, and the same dose once every 2 weeks thereafter. Aspergillus infection developed in 8 of 104 patients (7.7%) with n-LAB prophylaxis (5 colonization, 1 simple tracheobronchitis, 1 ulcerative tracheobronchitis, and 1 invasive pulmonary infection). Ulcerative tracheobronchitis and invasive pulmonary aspergillosis were regarded as invasive disease; hence, the rate of invasive disease was 1.9% (2 patients). The control group had similar rates of Aspergillus infection (10.2%; p = 0.6) and invasive disease (4.1%; p = 0.43). In 3 patients (2.9%), n-LAB was withdrawn due to bronchospasm in 2 and nausea in 1. In the control group, prophylaxis was stopped in 2 patients (4.1%) because of bronchospasm (p = 0.7). At the dose and frequency described, n-LAB seems effective, safe, and convenient for the prevention of Aspergillus infection in lung transplant patients.
