概括

在Candida血流感染中,较短的血培养时间到阳性 (TTP) 表明死亡率更高. 快速诊断和治疗至关重要,特别是在Candida auris感染时.

科学领域:

医学微生物学医学微生物学
传染性疾病传染性疾病
临床诊断临床诊断临床诊断

背景情况:

菌相关的血流感染 (CRBSI) 是一个重大的临床挑战,特别是在重症监护室 (ICU) 中,患有中央静脉导管 (CVC) 的患者.
血液培养物的时间到阳性 (TTP) 反映了真菌负载,可能表明感染严重程度和预后.

研究的目的:

为了评估TTP在Candida血流感染中的预后价值.
评估TTP对患者结局的影响,包括30天死亡率.

主要方法:

一项涉及怀疑患有候选血症的ICU患者的横截面观察研究.
使用BacT/ALERT 3D系统处理的血液培养物,记录Candida阳性培养物的TTP.
通过MALDI-TOF MS进行物种识别,并进行特定物种的30天死亡率分析.

主要成果:

在57名白血病患者中,与幸存者 (25小时,p=0.001) 相比,较短的TTP中位数 (24小时) 与死亡率相关.
黄菌的死亡率很高 (56.25%),平均TTP为16.5小时,相比之下,白菌没有死亡率 (平均TTP为28.5小时).
较短的TTP始终与Candida物种的死亡率增加相关.

结论:

TTP是Candida血流感染的有价值的预后标志物,较短的TTP预测了更高的死亡率.
快速诊断和积极的治疗是必不可少的,特别是在高风险物种,如白 Candida auris和白 Candida glabrata.
需要进一步的研究来优化TTP的临床应用,并指导有针对性的治疗策略.

Cryptococcal Meningitis

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Candidiasis

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
