摘要
目的观察2型糖尿病(T2DM)对脓毒症患者外周血单核细胞表面人白细胞DR抗原(HLA-DR)表达水平的影响。方法选取首都医科大学附属北京朝阳医院2021年3月至2022年2月收治的65例脓毒症合并T2DM(脓毒症合并T2DM组)、67例脓毒症未合并T2DM(脓毒症组)、60例T2DM患者(T2DM组)作为研究对象,以45例同期本院健康体检志愿者作为健康对照组。收集受试者性别、年龄、既往史、糖化血红蛋白(HbAlc)、入院时血糖、白细胞计数(WBC)淋巴细胞计数(LYM)超敏C-反应蛋白(hs-CRP)、主要感染部位,入院24h内进行序贯器官衰竭评分(SOFA)。采用流式细胞术检测外周血HLA-DR+CD14^(+)细胞表达百分比及平均荧光强度(MFI);并随访28d,观察T2DM对脓毒症患者28d预后的影响,比较不同预后患者HLA-DR^(+)CD14^(+)水平的差异。结果T2DM组HLA-DR^(+)CD14^(+)细胞表达百分比和MFI均明显低于健康对照组[HLA-DR^(+)CD14^(+)细胞表达百分比:87.72%(76.18%,93.64%)比94.86%(92.91%,95.70%),HLA-DR^(+)CD14^(+)MFI:10.80(8.45,14.45)比12.40(1.45,15.28)],脓毒症合并T2DM组和脓毒症组HLA-DRCD14^(+)细胞表达百分比和MFI均较健康对照组及T2DM组进一步降低[HLA-DR^(+)CD14^(+)细胞表达百分比:70.78%(42.22%,84.73%)、68.95%(44.95%,87.00%)比94.86%(92.91%,95.70%)、87.72%(76.18%,93.64%),HLA-DR^(+)CD14^(+)MFI:5.50(3.81,9.20)、5.29(3.35,9.59)比12.40(1.45,15.28)、10.80(8.45,14.45),均P<0.05]。脓毒症组和毒症合并T2DM组两组HLA-DR^(+)CD14^(+)细胞表达百分比和MFI、SOFA评分、28d病死率比较差异均无统计学意义(均P>0.05)。脓毒症组和脓毒症合并T2DM组死亡者的年龄明显大于生存者[岁:脓毒症组为68(60,74)比61(52,69),脓毒症合并T2DM组为66(64,73)比60(53,68),均P<0.05],SOFA评分明显高于生存者[分:脓毒症组为14(11,16)比8(5,11),脓毒症合并T2DM组为12(9,16)比8(6,11),均P<0.05],死亡组的HLA-DR^(+)CD14^(+)百分比和HLA-DR^(+)CD14^(+)MFI均明显低于生存组[HLA-DR^(+)CD14^(+)细胞表达百分比:脓毒症组为44.94%(28.01%,64.45%)比77.14%(47.41%,88.35%),脓毒症合并T2DM组为40.68%(34.83%,66.64%)比73.46%(58.44%,85.31%);HLA-DR^(+)CD14^(+)MFI:脓毒症组为3.92(2.30,5.44)比7.07(3.39,10.55),脓毒症合并T2DM组为3.90(3.34,6.04)比6.81(4.41,9.32),均P<0.05]。相关性分析显示:T2DM组、脓毒症组和脓毒症合并T2DM组HLA-DR^(+)CD14^(+)细胞表达百分比与hs-CRP均呈负相关(r值分别为-0.448、-0.628、-0.457,均P<0.001),MFI与hs-CRP亦呈负相关(r值分别为-0.289、-0.540、-0.323,均P<0.05)。脓毒症组和脓毒症合并T2DM组的HLA-DR^(+)CD14^(+)百分比与SOFA评分均呈负相关(r值分别为-0.520、-0.558,均P<0.001),MFI与SOFA评分也均呈负相关(r值分别为-0.327、-0.482,均P<0.01)。结论仑HLA-DR^(+)CD14^(+)水平在T2DM和脓毒症时均下降,但当脓毒症合并T2DM时,HLA-DR+CD14^(+)水平未发现进一步下降。
Objective To investigate the effect of type 2 diabetes mellitus(T2DM)on the expression of human leukocyte antigen-DR(HLA-DR)on the peripheral blood monocytes in patients with sepsis.Methods From March 2021 to February 2022,65 cases of sepsis with T2DM(sepsis with T2DM group),67 cases of sepsis without T2DM(sepsis group),and 60 cases of T2DM patients(T2DM group)admitted to Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects.A total of 45 healthy volunteers who underwent physical examination during the same period were enrolled as the healthy control group.Gender,age,past medical history,glycated hemoglobin(HbAlc),blood glucose at admission,white blood cell count(WBC),lymphocyte count(LYM),hypersensitivity C-reactive protein(hs-CRP)and major infection sites were collected,sequential organ failure assessment(SOFA)score was performed within 24 hours after admission.The levels of HLA-DR^(+)CD14^(+)in peripheral blood were detected by flow cytometry,expressed as a percentage and mean fluorescence intensity(MFI).The patients were followed up for 28 days.The effect of T2DM on the prognosis of sepsis patients at 28 days was observed,and the diference of HLA-DR^(+)CD14^(+)levels between the survivor group and the non-survivor group was compared.Results The percentage and MFI of HLA-DR^(+)CD14^(+)expressions in T2DM group were significantly lower than those in the healthy control group[the percentage of HLA-DR^(+)CD14^(+)expression:87.72%(76.18%,93.64%)vs.94.86%(92.91%,95.70%),HLA-DR^(+)CD14^(+)MFI:10.80(8.45,14.45)vs.12.40(1.45,15.28)],the sepsis with T2DM group and sepsis group were further reduced than those in healthy control group and T2DM group[the percentage of HLA-DR^(+)CD14^(+)expression:70.78%(42.22%,84.73%),68.95%(44.95%,87.00%)vs.94.86%(92.91%,95.70%),87.72%(76.18%,93.64%),MFI of HLADRCD14t:5.50(3.81,9.20),5.29(3.35,9.59)vs.12.40(1.45,15.28),10.80(8.45,14.45),all P<0.05].There was no significant difference in the percentage and MFI of HLA-DR^(+)CD14^(+)expressions,SOFA score,and 28-day mortality between sepsis group and sepsis with T2DM group(P>0.05).The age of the non-survivor group of sepsis patients with and without T2DM was significantly higher than that of the survivor group[years:sepsis group was 68(60,74)vs.61(52,69),sepsis with T2DM group was 66(64,73)vs.60(53,68),both P<0.05],and SOFA score was significantly higher than that of the survivor group[sepsis group:14(11,16)vs.8(5,11),sepsis with T2DM group:12(9,16)vs.8(6,11),both P<0.05],the percentage of HLA-DR^(+)CD14^(+)and HLA-DR^(+)CD14^(+)MFI in the non-survivor group were significantly lower than those in the survivor group[the percentage of HLA-DR^(+)CD14^(+)was 44.94%(28.01%,64.45%)vs.77.14%(47.41%,88.35%)in sepsis group and 40.68%(34.83%,66.64%)vs.73.46%(58.44%,85.31%)in sepsis with T2DM group,the MFI of HLA-DR^(+)CD14^(+)was 3.92(2.30,5.44)vs.7.07(3.39,10.55)in sepsis group and 3.90(3.34,6.04)vs.6.81(4.41,9.32)in sepsis with T2DM group,all P<0.05].Correlation analysis showed that the percentage of HLA-DR^(+)CD14^(+)in T2DM group,sepsis group,and sepsis with T2DM group was negatively correlated with hs-CRP(r values were-0.448,-0.628 and-0.457,all P<0.001),MFI was also negatively associated with hs-CRP(r values were-0.289,-0.540,-0.323,all P<0.05).The percentage of HLA-DR^(+)CD14^(+)in sepsis group and sepsis with T2DM group was negatively correlated with SOFA score(r values were-0.520 and-0.558,all P<0.001),and MFI was also negatively correlated with SOFA score(r values were-0.327 and-0.482,all P<0.01).Conclusion The levels of HLA-DR^(+)CD14^(+)decreased in both T2DM and sepsis patients,however,there was no further decrease in those patients with sepsis who also had T2DM.
