【摘要】：目的探討高遷移率族蛋白1(HMGB1)對膿毒癥及相關急性腎損傷(AKI)的診斷和預后的評估價值。方法選取2014年10月—2015年3月武漢大學人民醫(yī)院確診的膿毒癥患者40例,根據(jù)病情嚴重程度分為普通膿毒癥組12例和嚴重膿毒癥組28例。將嚴重膿毒癥組患者根據(jù)28 d病情轉歸情況分為惡化亞組13例和好轉亞組15例;又根據(jù)是否并發(fā)AKI分為嚴重膿毒癥AKI亞組18例,嚴重膿毒癥非AKI亞組10例,同樣根據(jù)28 d病情轉歸情況將18例嚴重膿毒癥AKI患者進一步分為惡化亞組11例和好轉亞組7例。另選取同期健康志愿者5例為對照組。收集患者入組24 h內的臨床資料并采集血、尿標本。酶聯(lián)免疫吸附法(ELISA)檢測血及尿HMGB1水平。采用SPSS 17.0軟件進行統(tǒng)計學分析。結果 (1)40例膿毒癥患者的血及尿HMGB1水平均高于對照組(P0.01)。嚴重膿毒癥組血HMGB1水平高于普通膿毒癥組,差異有統(tǒng)計學意義(P=0.027)。當以血HMGB1水平為1 225.1 ng/L作為鑒別嚴重膿毒癥與普通膿毒癥截斷點時,靈敏度與特異度分別為67.9%和75.0%,ROC曲線下面積為0.74〔95%CI(0.56,0.91),P=0.020〕。(2)Pearson相關分析結果顯示,血HMGB1水平與尿HMGB1水平、白細胞計數(shù)(WBC)及降鈣素原(PCT)呈正相關(r=0.472、0.597、0.473,P=0.011、0.001、0.011),尿HMGB1水平與估算腎小球濾過率呈正相關(r=0.480,P=0.010),與急性生理與慢性健康狀況評分系統(tǒng)Ⅱ(APACHEⅡ)評分、血肌酐水平呈負相關(r值分別為-0.506和-0.397,P值分別為0.006和0.038)。多元線性回歸分析結果顯示,尿HMGB1水平、WBC、PCT是嚴重膿毒癥組血HMGB1水平的影響因素,清蛋白與APACHEⅡ評分是尿HMGB1水平的影響因素(P0.05)。(3)當以尿HMGB1水平為961.0 ng/L作為截斷點時,鑒別嚴重膿毒癥惡化與好轉的靈敏度與特異度分別為73.3%和92.3%,ROC曲線下面積為0.84〔95%CI(0.69,0.99),P=0.002〕。(4)當以尿HMGB1水平為1 025.5 ng/L作為截斷點時,診斷膿毒癥AKI的靈敏度、特異度分別為70.0%和83.3%,ROC曲線下面積為0.73〔95%CI(0.53,0.93),P=0.046〕。(5)當以尿HMGB1水平為875.6 ng/L作為截斷點時,預測膿毒癥AKI預后的靈敏度、特異度分別為71.4%和90.9%,ROC曲線下面積為0.90〔95%CI(0,0.99),P=0.006〕。(6)采用二元Logistic回歸分析膿毒癥AKI患者疾病轉歸與血、尿HMGB1水平及臨床指標的相關性,結果顯示尿HMGB1水平及APACHEⅡ評分是膿毒癥患者AKI病情惡化的相關因素(b分別為0.010和-0.353,P值分別為0.037和0.046)。結論血、尿HMGB1在膿毒癥及相關AKI患者中均明顯升高,血HMGB1對膿毒癥病情嚴重程度有鑒別價值,尿HMGB1有助于診斷膿毒癥AKI并評估嚴重膿毒癥及膿毒癥AKI患者的預后。
[Abstract]:Objective to evaluate the value of high mobility group protein (HMGB1) in the diagnosis and prognosis of sepsis and associated acute renal injury (AKI). Methods Forty patients with sepsis diagnosed in the people's Hospital of Wuhan University from October 2014 to March 2015 were selected. According to the severity of the disease, the patients were divided into common sepsis group (n = 12) and severe sepsis group (n = 28). The patients in severe sepsis group were divided into worsening subgroup (n = 13) and improvement subgroup (n = 15). According to whether the patients were complicated with AKI, they were divided into severe sepsis AKI subgroup (18 cases) and severe sepsis non AKI subgroup (10 cases). According to the outcome of 28 days, 18 patients with severe sepsis AKI were further divided into deterioration subgroup (n = 11) and improvement subgroup (n = 7). Five healthy volunteers were selected as control group. Bed data and blood collection, Urine samples. Enzyme linked immunosorbent assay (Elisa) was used to detect HMGB1 levels in blood and urine. SPSS 17.0 software was used for statistical analysis. Results the serum and urine HMGB1 levels in 40 patients with sepsis were higher than those in control group (P 0.01). The serum HMGB1 level in severe sepsis patients was high. In the common sepsis group, When the blood HMGB1 level was 1 225.1 ng/L as the cut-off point for distinguishing severe sepsis from common sepsis, the sensitivity and specificity were 67.9% and 75.0%, respectively. There was a positive correlation between serum HMGB1 level and urinary HMGB1, leukocyte count and procalcitonin (PTC). There was a positive correlation between urinary HMGB1 level and glomerular filtration rate, and with acute physiological and chronic health scoring system 鈪，
