We describe an exceptional case of Candida tropicalis sepsis in a patient submitted to allogeneic BMT; the diagnosis was made on a peripheral blood smear, when the pt was neutropenic and only mildly febrile. The combination of GM-CSF to accelerate hematological recovery and the possibility of administering large doses of a liposomal form of Amphotericin B were the contributing factors to the resolution of the infection.

Eight patients with acute leukemia (AL) and invasive pulmonary aspergillosis (IPA) developing during previous antileukemic therapy underwent BMT (autologous in 6 cases and allogeneic 2). IPA was treated prior to BMT with full doses of amphotericin B, associated with surgical resection in three cases. One patient was treated with amphotericin B and itraconazole. Prior to BMT, seven patients had minimal residual pulmonary lesions. All patients received amphotericin B (0.5 mg/kg/day) during the aplastic period prior to engraftment. One patient died of Gram-negative septic shock before engraftment. Seven patients achieved complete hematological engraftment without any evidence of IPA reactivation. Amphotericin B was well tolerated with only minimal transient renal dysfunction in three patients. Later pulmonary complications related to IPA were observed in only one patient who developed a self-limited episode of hemoptysis. One patient died of CMV pneumonitis and two of leukemia relapse. Four patients survive disease-free and without complications related to IPA. We conclude that the reactivation of correctly treated IPA can be successfully prevented in BMT patients by use of prophylactic amphotericin B. With this approach, prior IPA is not a contraindication to BMT.

Amphotericin B colloidal dispersion (ABCD, AMPHOTEC, AMPHOCIL), a lipid complex of amphotericin B, was developed to reduce the nephrotoxicity of amphotericin B while retaining its antifungal efficacy. In this retrospective review, the efficacy and safety of ABCD were evaluated in 220 BMT recipients (167 allogeneic; 53 autologous) with suspected or documented life-threatening fungal infections (primarily Candida or Aspergillus species). Patients were treated in five open-label clinical trials of ABCD therapy. ABCD was administered intravenously once daily, median dose of 4 mg/kg, for up to 409 days (mean 23 days, median 16 days). Successful therapeutic response to treatment (complete or partial) was reported in 52% of the 99 evaluable patients with proven infection, and in 40% of all 220 patients. In the evaluable population, the response and mortality rates were 51% and 73%, respectively, in the allogeneic BMT patients, compared to 52% and 48% in the autologous BMT patients. The response rate for evaluable patients with Candida spp was 65%, 38% for patients with Aspergillus spp, and 42 % for patients with other or multiple fungal infections. In this patient population at high risk of nephrotoxicity due to concomitant cyclosporine and/or other nephrotoxic agents, ABCD did not cause renal dysfunction. Although the majority of patients had pre-existing renal impairment (median baseline serum creatinine 1.8 mg/dl), there was no trend towards increasing serum creatinine. No unexpected toxicities were observed. In conclusion, ABCD appears to be safe and effective for the treatment of severe fungal infections in BMT patients.
