Bloodstream infections from Candida species are associated with an increased length of stay, increased hospital costs, and higher mortality when compared with bacterial bloodstream infections. Delayed or inappropriate therapy in candidemia leads to increased mortality, thus early recognition becomes paramount. With biomarkers showing promise, blood cultures still remain the gold standard but require 24 to 72 hours for growth. The reliance on epidemiologic risk factors for the initiation of empiric antifungal therapy therefore provides the best method for early appropriate therapy. Shorr and colleagues have devised a risk score to identify patients with early-onset candidemia as defined by positive blood cultures within 2 days of admission, thus allowing for the initiation of early appropriate antifungal therapy.
与细菌性血流感染相比,念珠菌属引起的血流感染与住院时间延长、住院费用增加和死亡率升高有关。念珠菌血症治疗延迟或不当会导致死亡率增加,因此早期识别至关重要。由于生物标志物显示出前景,血液培养仍然是金标准,但需要 24 至 72 小时才能生长。因此,依靠流行病学危险因素来启动经验性抗真菌治疗是早期进行适当治疗的最佳方法。肖尔和同事设计了一个风险评分,以识别在入院后 2 天内血培养阳性的早发性念珠菌血症患者,从而可以开始早期适当的抗真菌治疗。
