背景

在一般成年人中,淋巴细胞减少与住院感染风险增加和感染相关死亡有关。不同手术方式的围手术期淋巴细胞减少与死亡率/发病率之间的相关性的证据质量和强度尚未通过系统回顾或Meta分析进行检验。

方法

检索MEDLINEEmbaseWeb of ScienceGoogle ScholarCochrane数据库,收集从建库到2020629日研究成人淋巴细胞计数和住院死亡率相关性的观察研究。术前淋巴细胞减少定义为淋巴细胞计数1.0-1.5×109L-1。使用固定或随机效应模型进行Meta分析。使用纽卡斯利-渥太华量表进行质量评估。用I2指数对异质性进行检验。主要观察指标是住院死亡率和30天内的死亡率。

结果

8项研究符合Meta分析的纳入标准,包括4811名患者(年龄范围,46-91岁;女性,20-79%)。这些研究只检查了术前淋巴细胞计数。总体来说,研究的质量为中到高等,纽卡斯利-渥太华标准等级>7。术前淋巴细胞减少与死亡率增加3倍(风险比(RR)=3.22;95%可信区间(CI),2.19-4.72;P<0.01,I2=0%)和更频繁的主要术后并发症(RR=1.33;95%CI,1.21-1.45;P<0.01,I2=25%)有关,包括心血管并发症(RR=1.77;95%CI,1.45-2.15;P<0.01,I2=0%)、感染(RR=1.45;95%CI,1.19-1.76;P<0.01,I2=0%)和急性肾功能不全(RR=2.66;95%CI,1.49-4.77;P<0.01,I2=1%)。

结论

术前淋巴细胞减少与死亡和并发症的发生率更高有关,与手术类型无关。

英文摘要 Abstract  


Preoperative lymphopaenia, mortality, and morbidity after elective surgery: systematic review and meta-analysis


Background: In the general adult population, lymphopaenia is associated with an increased risk for hospitalisation with infection and infection-related death. The quality of evidence and strength of association between perioperative lymphopaenia across different surgical procedures and mortality/morbidity has not been examined by systematic review or meta-analysis.


Methods: We searched MEDLINE, Embase, Web of Science, Google Scholar, and Cochrane databases from their inception to June 29, 2020 for observational studies reporting lymphocyte count and in-hospital mortality rate in adults. We defined preoperative lymphopaenia as a lymphocyte count 1.0-1.5×109L-1. Meta-analysis was performed using either fixed or random effects models. Quality was assessed using the NewcastleeOttawa Scale. The I2 index was used to quantify heterogeneity. The primary outcome was in-hospital mortality rate and mortality rate at 30 days.


Results: Eight studies met the inclusion criteria for meta-analysis, comprising 4811 patients (age range, 46-91 yr; female,20-79%). These studies examined preoperative lymphocyte count exclusively. Studies were of moderate to high quality overall, ranking >7 using the Newcastlee Ottawa Scale. Preoperative lymphopaenia was associated with a threefold increase in mortality rate (risk ratio [RR]=3.22; 95% confidence interval [CI], 2.19-4.72; P<0.01, I2=0%) and more frequent major postoperative complications (RR1.33; 95% CI, 1.21-1.45; P<0.01, I2=6%), including cardiovascular morbidity (RR=1.77; 95% CI, 1.45-2.15; P<0.01, I2=0%), infections (RR=1.45; 95% CI, 1.19-1.76; P<0.01, I2=0%), and acute renal dysfunction (RR=2.66; 95% CI, 1.49-4.77; P<0.01, I2=1%).


Conclusion: Preoperative lymphopaenia is associated with death and complications more frequently, independent of the type of surgery.
