Abstract

Amphotericin B remains the treatment of choice for systemic fungal infections, but amphotericin B is toxic and is often not effective in treating disseminated infections. Liposome intercalation of amphotericin B reduces the toxicity associated with amphotericin B and targets reticuloendothelial tissues most heavily involved in fungal infections. The targeted delivery and reduced toxicity of liposomal amphotericin B improves the therapeutic index of amphotericin B. Although liposomes have been shown to effectively treat a variety of experimental and human fungal infections, the optimal composition of liposomal amphotericin has not been established. Vesicle type, lipid content, size, and conditions of storage markedly affect toxicity, therapeutic efficacy, and tissue distribution. In vitro studies have been poor predictors of in vivo efficacy and toxicity. Animal models can be used to evaluate in vivo the optimal liposome preparation. Liposomal amphotericin B appears to be an improved means of amphotericin B delivery and may improve the treatment of patients with systemic fungal infections.

两性霉素B脂质体在治疗全身真菌感染中的作用。
两性霉素B仍然是全身性真菌感染的治疗选择,但两性霉素B是有毒的,通常对治疗播散性感染无效。两性霉素B的脂质体嵌入降低了两性霉素B的毒性,并靶向与真菌感染最密切相关的网状内皮组织。两性霉素B脂质体的靶向递送和毒性的降低提高了两性霉素B的治疗指数。尽管脂质体已被证明能有效治疗多种实验和人类真菌感染,但两性霉素脂质体的最佳组成尚未确定。囊泡类型、脂质含量、大小和储存条件显著影响毒性、治疗效果和组织分布。体外研究不能很好地预测体内疗效和毒性。动物模型可用于体内评价脂质体的最佳制备方法。两性霉素B脂质体似乎是两性霉素B递送的一种改进手段,并可能改善全身性真菌感染患者的治疗。
