脓毒症休克患者血清视黄醇结合蛋白、β2微球蛋白水平与病情、疾病转归的关系

Correlation of serum retinol-binding protein andβ2-microglobulin levels with disease and disease outcome in patients with septic shock

目的 分析脓毒症休克患者血清视黄醇结合蛋白(RBP)、β2微球蛋白(β2-MG)水平与病情、疾病转归的关系。方法 选取2020年11月至2022年11月在钦州市中医医院收治的120例脓毒症患者作为研究对象,按照病情严重程度分为脓毒症组76例和脓毒症休克组44例。另选同期该院体检健康者96例为对照组。根据脓毒症休克组患者28 d疾病转归情况分为死亡患者10例(恶化组)、生存患者34例(转归组)。所有对象入院后24 h内采用免疫比浊法检测血清RBP、β2-MG水平。比较各组血清RBP、β2-MG水平,采用受试者工作特征曲线(ROC)评估血清RBP、β2-MG对脓毒症休克患者疾病转归的预测价值,采用多因素Logistic回归分析影响脓毒症休克患者疾病转归的相关因素。结果 脓毒症休克组白细胞计数、降钙素原、C反应蛋白水平及急性生理学与慢性健康状况评分系统Ⅱ评分、序贯器官衰竭评估(SOFA)评分均高于脓毒症组、对照组,血小板计数低于脓毒症组、对照组,差异有统计学意义(P<0.05)。脓毒症休克组血清RBP、β2-MG水平均高于脓毒症组、对照组,差异有统计学意义(P<0.05)。恶化组血清RBP、β2-MG水平均高于转归组,差异有统计学意义(P<0.05)。ROC曲线分析显示,血清RBP、β2-MG联合评估脓毒症休克疾病转归的曲线下面积为0.910(95%CI:0.865~0.955)。多因素Logistic回归分析发现,血清RBP、β2-MG及C反应蛋白、SOFA评分均为影响脓毒症休克患者疾病转归的危险因素(P<0.05)。结论 脓毒症休克患者血清RBP、β2-MG水平均升高,二者水平变化与疾病转归有关,联合应用对脓毒症休克患者疾病转归具有更好的预测价值。

Objective To explore the correlation between serum levels of retinol-binding protein(RBP)andβ2-microglobulin(β2-MG)levels with the disease and disease outcome in patients with septic shock.Methods A total of 120 patients with sepsis admitted to Qinzhou Hospital of Traditional Chinese Medicine from November 2020 to November 2022 were selected as research objects,and divided into sepsis group(76 cases)and septic shock group(44 cases)according to the severity of the disease.A total of 96 healthy subjects were selected as control group.According to the 28-day disease outcome of sepsis shock group,10 patients died(worsening group)and 34 patients survived(outcome group).Serum RBP andβ2-MG levels were detected by immunoturbidimetry within 24 h after admission.Serum RBP andβ2-MG levels were compared among all groups.Receiver operating characteristic curve(ROC)was used to evaluate the predictive value of serum RBP andβ2-MG on the disease outcome of patients with septic shock.Multivariate Logistic regression was used to analyze the related factors affecting the disease outcome of patients with septic shock.Results WBC count,procalcitonin,C reactive protein level,acute physiology and chronic health status score systemⅡscore,sequential organ failure assessment(SOFA)score in sepsis shock group were higher than those in sepsis group and control group,and platelet count was lower than those in sepsis group and control group,the difference was statistically significant(P<0.05).Serum RBP andβ2-MG levels in sepsis shock group were higher than those in sepsis group and control group,and the difference was statistically significant(P<0.05).The levels of serum RBP andβ2-MG in the worsening group were higher than those in the outcome group,and the difference was statistically significant(P<0.05).ROC curve analysis showed that the area under the curve of serum RBP andβ2-MG combined to evaluate the outcome of septic shock disease was 0.910(95%CI:0.865-0.955).Multivariate Logistic regression analysis showed that serum RBP,β2-MG,C reactive protein and SOFA score were all risk factors affecting the disease outcome of septic shock patients(P<0.05).Conclusion The serum levels of RBP andβ2-MG in patients with septic shock are increased,and the changes of both levels are related to the disease outcome.The combined application has a better predictive value for the disease outcome in patients with septic shock.
