Amongst 310 recipients of live related renal transplants, systemic fungal infections were observed in 19 patients (6.1%). These included cryptococcosis in eight (42%), candidiasis in seven (37%), mucormycosis in two (11%), aspergillosis in one (5.5%), and a mixed cryptococcal and Aspergillus infection in one patient (5.5%). Infections occurred within 12 months of transplantation in seven patients and after 13-37 months in the remaining patients. Prolonged fever not responding to antibiotics was the most common presentation. Central nervous system was involved in all patients with cryptococcosis, while Candida infection primarily involved the urinary tract. Both patients with mucormycosis exhibited signs and symptoms of florid rhinocerebral disease and a rapid downhill course. Pulmonary manifestations were the most prominent features of patients with aspergillosis. Parenteral amphotericin B with or without 5-fluorocytosine was started in all, but three patients could receive the therapy only for 1-3 weeks. Three patients with cryptococcosis developed amphotericin-related complications and were changed to oral fluconazole. Seven patients recovered and 12 (63%) died. None of the patients had cytomegalovirus infection preceding the onset of fungal disease. The high frequency of fungal infections amongst our allograft recipients could not be ascribed to over immunosuppression, since 16 patients (84%) were only on maintenance doses of immunosuppressive drugs and in 13 (68.4%) graft function was normal at the time of diagnosis. The high frequency of fungal infections in our patients was most probably related to the poor hygienic and sanitary conditions which continue to be prevalent in the tropical environment of third-world countries. Delays in the diagnosis and late institution of therapy result in a high mortality.(ABSTRACT TRUNCATED AT 250 WORDS)
在310例亲属活体肾移植受者中,有19例(6.1%)发生了系统性真菌感染。其中8例(42%)为隐球菌病,7例(37%)为念珠菌病,2例(11%)为毛霉菌病,1例(5.5%)为曲霉菌病,1例患者(5.5%)为隐球菌与曲霉菌混合感染。7例患者在移植后12个月内发生感染,其余患者在13 - 37个月后发生感染。抗生素治疗无效的持续发热是最常见的表现。所有隐球菌病患者的中枢神经系统均受累,而念珠菌感染主要累及泌尿系统。2例毛霉菌病患者均表现出严重鼻脑疾病的体征和症状,且病情迅速恶化。肺部表现是曲霉菌病患者最突出的特征。所有患者均开始使用含或不含5-氟胞嘧啶的静脉两性霉素B治疗,但3例患者仅接受了1 - 3周的治疗。3例隐球菌病患者出现了两性霉素相关并发症,改为口服氟康唑治疗。7例患者康复,12例(63%)死亡。在真菌病发病前,所有患者均无巨细胞病毒感染。我们的同种异体移植受者中真菌感染的高发生率不能归因于免疫抑制过度,因为16例患者(84%)仅接受维持剂量的免疫抑制药物治疗,13例(68.4%)在诊断时移植肾功能正常。我们患者中真菌感染的高发生率很可能与第三世界国家热带环境中普遍存在的恶劣卫生条件有关。诊断延迟和治疗开始较晚导致了高死亡率。(摘要截选至250字)
