Abstract:
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(HbA1c),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 difference 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 HLA-DR+CD14+: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(rvalues 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.
