    Abstract:
    The use of high-dose chemotherapy and the subsequent prolonged neutropenia in patients with haematological diseases has resulted in an increased incidence of fungal infections. The only drug with proven efficacy in the treatment of deep seated fungal infections or invasive aspergillosis is amphotericin B. Unfortunately, this drug has adverse side effects, most importantly dose dependent nephrotoxicity. Furthermore, some patients fail to show a response to amphotericin B. We have treated 40 patients undergoing myeloablative chemotherapy and or bone marrow transplantation for haematological diseases with liposomal amphotericin for proven or suspected fungal infections. All patients had failed treatment with conventional Amphotericin B. Fourteen patients received liposomal amphotericin (AmBisome) due to progression of infection on conventional amphotericin B. Twenty six patients received liposomal amphotericin due to nephrotoxicity caused by conventional Amphotericin B. Nine patients had mycologically proven fungal infection and of these, 7 patients (78%) showed a complete response to liposomal amphotericin. Thirty one patients received liposomal amphotericin due to suspected fungal infection. Eleven of these 31 patients (35%) showed a complete clinical response to liposomal amphotericin. However in the patients with suspected fungal infections 14 patients had no response and 6 patients could not be evaluated for response to liposomal amphotericin. Overall, of the 18 patients showing a response to liposomal amphotericin, 15 patients had either recovered their neutrophil count (> 0.5 x 10(9)/l) or achieved remission from their underlying haematological disease. Recovery from fungal infection in this group of patients occurred when there was complete remission of underlying disease and recovery of neutrophil counts, when concurrently treated by liposomal amphotericin.
