Invasive aspergillosis is a severe complication in the immunocompromised patient. Despite antifungal treatment the mortality rate is higher than 90% if the immunity deficiency is not corrected. The use and dosage of conventional amphotericin B (deoxycholate-suspended formulation) is limited by its toxicity, especially nephrotoxicity. To reduce these untoward effects, amphotericin B has been formulated in liposomes. Better tolerance and lower nephrotoxicity in the liposomal formulations allow higher doses to be given safely, even in the presence of renal failure. Liposomal encapsulated amphotericin B (LAmB) is a safe and effective alternative to conventional formulations for antifungal therapy. We present a case of a 60-year-old man affected by chronic lymphocytic leukaemia. In the course of his disease and after chemotherapy treatment, he presented an invasive aspergillosis of the lung and paransal sinuses. The rhino-sinusal lesion had progressed despite surgical debridement and treatment with amphotericin B in a dosage of 50 mg per day. Moreover, renal impairment caused by conventional amphotericin was detected. Then, LAmB was started at a dose of 150 mg per day. Treatment with LAmB has resulted in clinical recovery and radiologic ressolution.
侵袭性曲霉病是免疫功能低下患者的一种严重并发症。如果免疫缺陷得不到纠正,尽管进行了抗真菌治疗,死亡率仍高于90%。传统两性霉素B(脱氧胆酸盐悬浮制剂)的使用和剂量受到其毒性的限制,尤其是肾毒性。为了减少这些不良反应,两性霉素B已制成脂质体剂型。脂质体制剂具有更好的耐受性和更低的肾毒性,即使在存在肾衰竭的情况下也能安全地给予更高剂量。脂质体包裹的两性霉素B(LAmB)是抗真菌治疗中传统制剂的一种安全有效的替代药物。我们报告一例60岁男性慢性淋巴细胞白血病患者。在其病程中及化疗后,出现了肺部和鼻窦的侵袭性曲霉病。尽管进行了手术清创并每天使用50mg两性霉素B治疗,但鼻窦病变仍有进展。此外,检测到传统两性霉素导致的肾功能损害。然后,开始每天使用150mg的LAmB治疗。LAmB治疗导致了临床康复和影像学改善。
