The aim of the present study was to analyze the main clinical and evolutive characteristics of a series of 10 patients diagnosed with sepsis by Candida tropicalis over a 5-year period in a Hematology Unit. The mean age of the 10 patients was 23 years (range 13-66 years) with 6 males and 4 females. Eight patients had acute leukemia, 1 non-Hodgkin's lymphoma and another patient had severe bone marrow aplasia. All the patients presented intense granulocytopenia (< 0.5 x 10(9)/L), had intravenous catheters and were receiving wide spectrum antibiotics as treatment for bacterial infection. The diagnosis of the fungal infection was based on the growth of C. tropicalis in blood cultures together with the evidence of tissue involvement by the fungus. Fever (> 38 degrees C) was the initial symptom of the infection in all the patients, being accompanied by myalgia in 5 cases, pleuritic pain in 2 and septic shock in 1. Violaceous erthymatomous pustules disseminated over the trunk and limbs, the histologic study of which demonstrated the presence of C. tropicalis were observed in 9 patients. Septic metastasis were found in the liver (2 cases), serosae (2 cases), the psoas muscle and the brain (1 case), respectively. Eight patients underwent treatment with amphotericin B which was complemented with 5-fluorocytosin in 6, with death occurring in the remaining 2 patients prior to the start of treatment. Three patients died with active fungal infection (2 by cerebral hemorrhage and 1 by septic shock). In 2 patients the infection evolved to chronic systemic candidiasis and in the remaining 5 patients infection was resolved with hemoperipheral values returning to normal. Sepsis by Candida tropicalis is a severe complication in patients with granulocytopenia, being mainly characterized by fever, cutaneous papulae and, to a lesser extent, muscle pain. Amphotericin B alone, or in combination with 5-fluorocytosin constitute a treatment of choice in this infection, which nonetheless is associated with an undisdainful mortality.
本研究的目的是分析血液科5年间确诊的10例热带念珠菌败血症患者的主要临床和演变特征。10例患者的平均年龄为23岁(范围13 - 66岁),其中男性6例,女性4例。8例患者患有急性白血病,1例患有非霍奇金淋巴瘤,另1例患有严重骨髓再生障碍。所有患者均出现严重粒细胞减少(< 0.5×10⁹/L),均有静脉导管且正在接受广谱抗生素治疗细菌感染。真菌感染的诊断基于血液培养中热带念珠菌的生长以及真菌组织受累的证据。发热(> 38℃)是所有患者感染的初始症状,5例伴有肌痛,2例伴有胸膜炎性疼痛,1例伴有感染性休克。9例患者躯干和四肢出现紫罗兰色红斑脓疱,组织学研究显示存在热带念珠菌。分别在肝脏(2例)、浆膜(2例)、腰大肌和脑(1例)发现感染性转移。8例患者接受了两性霉素B治疗,其中6例联合5-氟胞嘧啶,其余2例在治疗开始前死亡。3例患者死于活动性真菌感染(2例死于脑出血,1例死于感染性休克)。2例患者感染演变为慢性系统性念珠菌病,其余5例患者感染得到解决,外周血象恢复正常。热带念珠菌败血症是粒细胞减少患者的严重并发症,主要特征为发热、皮肤丘疹,肌肉疼痛相对较轻。单独使用两性霉素B或与5-氟胞嘧啶联合使用是这种感染的首选治疗方法,尽管如此,其死亡率仍不容小觑。
