Few cases of cryptococcal infection following umbilical cord blood transplantation (UCBT) have been reported. We report a case, where cryptococcal infection occurred soon after rapidly reducing the dose of tacrolimus in a UCBT recipient who received micafungin prophylaxis during the early phase of transplantation. The etiology of cryptococcal infection following allogeneic hematopoietic stem cell transplantation (allo-HSCT), including UCBT, might be associated with rapid dose-reduction of calcineurin inhibitors, such as tacrolimus during early phase of allo-HSCT. To our knowledge, this is the first English-language report to describe in detail a case of cryptococcal meningitis with fungemia during early phase of UCBT. 相似文献

隐球菌病是由隐球菌感染人体引起的一种侵袭性真菌病,是艾滋病患者及实体器官移植者中常见的感染和致死原因.10年来,隐球菌病的诊断方法 已从真菌培养、墨汁染色,到目前的隐球菌荚膜抗原(cryptococcal capsular antigen,CrAg)检测.CrAg检测操作简便快速,花费少,敏感性及特异性高,因此在世界范... 相似文献

肺隐球菌病是一种吸入隐球菌孢子而引起的肺急性、亚急性或慢性真菌病,易播散至中枢神经系统而导致隐球菌性脑膜炎,病死率和致残率高。近年肺隐球菌病的发病率呈增长趋势。肺隐球菌病的临床症状及体征、肺部影像学及实验室检查均缺乏特异性,因此极易漏诊、误诊。河北省胸科医院病理科近期会诊一例肺隐球菌病并发纵隔淋巴结结核患者,曾在外院就诊时经影像学及临床检查误诊为肺癌,术后病理误诊为肺结核,经我院会诊其病理切片及进行辅助检查(特殊染色、结核分枝杆菌核酸检测)后最终明确诊断。现结合相关文献回顾性分析其临床、影像及病理特点,以期提高其诊断水平,避免误诊误治。 相似文献

Cryptococcosis is a fungal infection of the central nervous system predominantly caused by Cryptococcus neoformans in immunocompromised patients. In several countries worldwide, up to 50% of isolates show in vitro resistance to clinically used antifungals including fluconazole. No prospective data on susceptibility to antifungal drugs are available for Germany. In this study, we characterised all C. neoformans isolates collected from individual patients’ samples at the German reference laboratory for cryptococcosis 2011 and 2017 (n = 133) by multi-locus sequence typing and phenotypic drug susceptibility testing. We identified serotype A/genotype VNI isolates belonging to clonal complexes previously described from Europe, Africa, Asia and South America as the most prevalent agents of cryptococcosis in Germany. Overall, we observed minimal inhibitory concentrations (MICs) above the epidemiological cut-offs (ECVs) in 1.6% of isolates regarding fluconazole and 2.3% of isolates regarding 5-flucytosine. Here, two C. neoformans var. grubii isolates displayed decreased drug susceptibility to fluconazole, one of them additionally to 5-flucytosine. We also found 5-flucytosine MICs above the ECV for two C. neoformans var. neoformans isolates. We identified a novel mutation in the ERG11 gene which might be associated with the elevated fluconazole MIC in one of the isolates. The clinical importance of the detected in vitro resistance is documented by patient histories showing relapsed infection or primary fatal disease. Of note, sertraline demonstrated antifungal activity comparable to previous reports. Systematic collection of susceptibility data in combination with molecular typing of C. neoformans is important to comprehensively assess the spread of isolates and to understand their drug resistance patterns. 相似文献

The incidence of systemic fungal infections that has risen dramatically over the past three decades has propelled a continuous need for more potent antifungal drugs. The purpose of this research was to evaluate the chemotherapeutic activity of a new heptaene polyene macrolide antibiotic (SJA-95) and liposomal incorporated SJA-95 (lip. SJA-95) in a mouse model of aspergillosis and cryptococcosis respectively. Lip. SJA-95 was prepared in our laboratory by the proliposome method involving incorporation of the antifungal into the proliposome mixture and its subsequent conversion into a liposomal dispersion by a simple dilution step. Treatment with free SJA-95 and lip. SJA-95, both in aspergillosis and cryptococcosis, progressively prolonged the survival time and decreased the fungal loads in vital organs respectively. A higher LD50 value of lip. SJA as compared to that of free SJA-95 was indicative of reduced toxicity of lip. SJA-95. Our findings suggest lip. SJA-95 treatment results in prolonged survival time, effective microbiological clearance and reduced toxicity that might help to establish its usefulness as a chemotherapeutic agent in systemic fungal infections with fewer adverse reactions. 相似文献

While studies in kidney recipients have found meningitis to be the most common clinical manifestation of cryptococcosis (Cry), it is unclear if the clinical presentation of Cry differs among various solid-organ transplant (SOT) recipients and whether the serum cryptococcal antigen (SCA) might predict the site of infection. We report the clinical manifestations and the correlation with a positive SCA among 55 consecutive SOT recipients diagnosed with Cry at the University of Pittsburgh Medical Center. These included: heart (n=13), lung (n=4), liver (n=28), kidney (n=9) and small bowel (n=1) recipients. While there were no significant differences in the manifestations of Cry in heart and lung recipients, kidney recipients had disseminated disease as the most common presentation (P=0.02). In contrast, pneumonia (P=0.003) and meningitis (P=0.02) were more frequent than disseminated disease in liver recipients. Positive SCA was higher in patients with disseminated disease and meningitis than in patients with isolated pneumonia (P=0.0001). Significant differences in the manifestations of Cry were observed among types of SOT populations. A positive SCA may be predictive of dissemination and meningitis, but it may not be sensitive for pulmonary disease. 相似文献
