INTRODUCTION: Although amphotericin was the gold standard in the treatment of invasive aspergillosis in transplant recipients, nephrotoxicity and lack of efficacy often limits its use. Itraconazole is better tolerated but less efficacious and influences immunosuppressant trough levels significantly. We report our first clinical experience with the use of caspofungin as first-line therapy in heart and lung transplant recipients with invasive aspergillosis. METHODS: Caspofungin was administered at 50 to 70 mg/day in heart and lung transplant recipients with renal impairment while invasive aspergillosis was diagnosed and classified. Aspergillus serology, serologic inflammatory markers, and X-rays were taken to monitor infectious activity. Creatinine and immunosuppressant trough levels were monitored closely. RESULTS: Invasive aspergillosis was diagnosed by chest X-ray, serology, and positive sputum in 1 heart-lung, 7 heart, and 4 single-lung transplant recipients, and caspofungin was administered for a mean time of 21 +/- 9 days. Basic immunosuppressants were tacrolimus in 9 patients or cyclosporine in 3. Complete remission was achieved in 10 patients (83%). Adverse effects of caspofungin were fever in 6, diarrhea in 3, and neutropenia in 1. Renal function remained stable (3.2 +/- 1 mg/dl before vs 2.3 +/- 0.9 mg/dl after, p = 0.07). Trough levels of all immunosuppressants did not change significantly during caspofungin treatment (10.9 +/- 4.1 ng/ml before vs 9.9 +/- 4.0 ng/ml after [p = 0.31] for tacrolimus; 214 +/- 98 ng/ml before vs 229 +/- 88 ng/ml after [p = 0.41] for cyclosporin A), while the administered dosage remained stable. CONCLUSION: In heart and lung transplant recipients with invasive aspergillosis, caspofungin seemed to be an effective anti-fungal agent with a promising safety profile. Further prospective randomized trials are needed to investigate an advantageous role of caspofungin in the treatment of invasive aspergillosis.
