RESUMEN
Background: In patients with persistent fever and netropenia, amphotericin B is administered empirically for early treatment and prevention of systemic fungal infections. Despite this treatment, there are chances of breakthrough fungal infections and drug is also toxic. Materials and Methods: A multicentric, randomized, controlled clinical trial was conducted to compare liposomal amphotericin B two doses with conventional amphotericin B as empirical antifungal therapy. Results: The average body weight of patients was 26.4±14.8 (n=22), 32.9±19.4 (n=23) and 37.9±20.0 (n=20) kg in 1 mg, 3 mg Fungisome (liposomal amphotericin B) and 1 mg/kg/day conventional amphotericin B group, respectively. The mean age was 16.2±13.4, 16.0±10.9 and 22.7±16.2 yrs in 1 and 3 mg/kg/day Fungisome and 1 mg/kg/day conventional AMP B group, respectively. The average duration of treatment with 1 mg and 3 mg/kg/day Fungisome and 1 mg/kg/day conventional amphotericin B was 17±9.8, 16.2±8.3, and 14.7±10.7 days, respectively. The time to resolve fever was 13.3±10.2, 10.9±7.1, 10.1±6.7 days, and for absolute neutrophil count (ANC) to be above 500 cells per microliter, it took 13.4±9.6, 10.6±7.6 and 7.3±3.4 days, respectively. Liposomal formulations were well-tolerated compared to conventional amphotericin B. Conclusions: This small randomized study showed that the indigenous liposomal formulation Fungisome TM appears to be equally efficacious and safer than conventional amphotericin B. Also, the lower dose Fungisome (1 mg/kg/day) appears to be equally efficacious and was well-tolerated as compared to higher dose Fungisome (3 mg/kg/day). Treatment cost would be a major factor for limiting use of higher dose of Fungisome.
