Among recipients of intra-abdominal solid-organ transplants, bloodstream infections (BSIs) are a major cause of mortality. We undertook a retrospective cohort study of recipients of kidney, pancreas, and/or liver transplants with BSIs at a single center over an 11-year period. Multivariate analysis using logistic regression was used to determine independent predictors of 15-day mortality and clinical cure, with a focus on the use of statins. Three hundred and eleven recipients of solid-organ transplants had 604 episodes of BSI. Forty-four (14%) died within 15 days of BSI. Sixteen percent did not achieve clinical cure. In the multivariate model, each one point increase in the APACHE score was associated with a 1.09-fold increased risk of death (95% confidence interval [CI] 1.00-1.18, P = 0.03). The lack of appropriate antibiotic therapy was associated with a four-fold higher risk of death within 15 days (odds ratio [OR] 4.65, 95% CI 1.46-14.78, P = 0.009). Statin use was protective (OR 0.18, 95% CI 0.04-0.78). Patients with high APACHE scores, nosocomial rather than community source of BSI, lack of appropriate antibiotic therapy, and mental status changes were less likely to achieve clinical cure of their BSIs. In conclusion, appropriate antibiotic therapy and statin use are associated with lower risk of mortality from BSIs in this patient population.
在接受腹腔内实体器官移植的患者中,血流感染(BSI)是导致死亡的主要原因。我们对在一家中心接受肾、胰腺和/或肝移植并在 11 年内发生 BSI 的患者进行了回顾性队列研究。使用逻辑回归进行多变量分析,以确定 15 天死亡率和临床治愈率的独立预测因素,重点是他汀类药物的使用。311 名接受实体器官移植的患者发生了 604 次 BSI。44 例(14%)在 BSI 发生后 15 天内死亡。16%的患者未达到临床治愈。在多变量模型中,APACHE 评分每增加 1 分,死亡风险增加 1.09 倍(95%置信区间 [CI] 1.00-1.18,P=0.03)。抗生素治疗不当与 15 天内死亡风险增加四倍相关(比值比 [OR] 4.65,95%CI 1.46-14.78,P=0.009)。他汀类药物的使用具有保护作用(OR 0.18,95%CI 0.04-0.78)。APACHE 评分高、医院来源而非社区来源的 BSI、抗生素治疗不当和精神状态改变的患者,其 BSI 的临床治愈率较低。总之,在该患者群体中,适当的抗生素治疗和他汀类药物的使用与降低 BSI 死亡率的风险相关。
