Abstract

Background: Sepsis accounts for a significant proportion of global deaths and has limited treatment options. Cancer patients are at a higher risk of sepsis and experience worse outcomes, highlighting the complex interplay between sepsis and cancer on immune cell function and clinical prognosis.

Methods: Between July and December 2023, we prospectively enrolled 30 sepsis patients and 10 healthy controls, categorizing the patients into sepsis with non-cancer and sepsis with cancer based on established clinical diagnostics. Multi-color flow cytometry was used to monitor changes in the expression of surface molecules of monocyte and neutrophil subsets, phagocytic activity and cytokine-producing capacity.

Results: Compared with sepsis with non-cancer, the sepsis with cancer group demonstrated elevated 28-day mortality rates, increased CD177+ activated band neutrophil and HLA-DRlowCCR2low classical monocyte, and attenuated phagocytic activity of immature neutrophil and monocyte. Further, HLA-DRlowCCR2low classical monocytes and CD177+ myelocytes may serve as immunological predictors of adverse outcomes in sepsis. The HLA-DRlowCCR2low classical monocyte and CD177+ myelocytes exhibit significant correlations with internal environment and coagulation markers.

Conclusion: In septic patients, particularly those patients with cancer, attenuated phagocytic activity of immature neutrophil (myelocytes, metamyelocytes, band neutrophils) and monocyte, and HLA-DRlowCCR2low classical monocyte and CD177+ myelocytes may serve as immunological predictors of poor prognosis.

脓毒症伴癌以骨髓细胞区室失调为标志:一项初步研究。
背景:脓毒症在全球死亡中占很大比例,治疗选择有限。癌症患者脓毒症的风险更高,预后更差,这突出了脓毒症和癌症之间对免疫细胞功能和临床预后的复杂相互作用。方法:2023年7月至12月,前瞻性纳入30例脓毒症患者和10例健康对照,根据已建立的临床诊断将患者分为非癌性脓毒症和癌性脓毒症。采用多色流式细胞术监测单核细胞和中性粒细胞亚群表面分子表达、吞噬活性和细胞因子产生能力的变化。结果:与非癌性脓毒症组相比,癌性脓毒症组28天死亡率升高,CD177+活化带中性粒细胞和HLA-DRlowCCR2low经典单核细胞增多,未成熟中性粒细胞和单核细胞吞噬活性减弱。此外,HLA-DRlowCCR2low经典单核细胞和CD177+髓细胞可能作为败血症不良结局的免疫学预测因子。HLA-DRlowCCR2low经典单核细胞和CD177+髓细胞与内环境和凝血标志物有显著相关性。结论:在脓毒症患者,特别是癌症患者中,未成熟中性粒细胞(髓细胞、化髓细胞、带状中性粒细胞)和单核细胞、HLA-DRlowCCR2low经典单核细胞和CD177+髓细胞的吞噬活性减弱可能是不良预后的免疫学预测因子。
