【摘要】目的探討T淋巴細(xì)胞內(nèi)三磷酸腺苷T cell-iATP)水平預(yù)測(cè)膿毒癥并發(fā)急性腎損傷(AKI)患者預(yù)后的價(jià)值。方法前瞻性選擇2013年7月—2014年12月于麗水市中心醫(yī)院ICU、感染科及腎內(nèi)科住院的膿毒癥并發(fā)AKI患者69例為研究對(duì)象,分別于入組0、48、96 h檢測(cè)患者T cell-iATP水平。根據(jù)腎功能臨床轉(zhuǎn)歸情況將患者分為腎功能完全恢復(fù)組(18例)、腎功能部分恢復(fù)組(38例)、依賴透析組(4例)和死亡組(9例)。結(jié)果各組eGFR、功能衰竭臟器數(shù)量、AKI分期及0、48 hT cell-iATP水平比較,差異有統(tǒng)計(jì)學(xué)意義(P<0.05)。多分類Logistic回歸分析結(jié)果顯示,相對(duì)于預(yù)后不良(依賴透析或死亡),eGFR、功能衰竭臟器數(shù)量和48 hT cell-iATP水平為腎功能完全恢復(fù)、腎功能部分恢復(fù)的影響因素(P<0.05)。ROC曲線分析顯示,48 hT cell-iATP水平預(yù)測(cè)膿毒癥并發(fā)AKI患者預(yù)后的ROC曲線下面積為0.926(P<0.01),取48 hT cell-iATP臨界點(diǎn)為344.2 μg/L時(shí),靈敏度為92.3%,特異度為87.5%。結(jié)論T cell-iATP水平低的膿毒癥患者腎功能恢復(fù)良好,膿毒癥患者早期T cell-iATP水平是腎功能轉(zhuǎn)歸的預(yù)測(cè)指標(biāo)。

1對(duì)象與方法
1.1研究對(duì)象前瞻性選擇2013年7月—2014年12月于麗水市中心醫(yī)院ICU、感染科及腎內(nèi)科住院的膿毒癥并發(fā)AKI患者69例為研究對(duì)象,均符合2001年美國(guó)胸科醫(yī)師學(xué)會(huì)(ACCP)和重癥醫(yī)學(xué)會(huì)(SCCM)膿毒癥的診斷標(biāo)準(zhǔn)[4];根據(jù)急性腎損傷網(wǎng)絡(luò)(AKIN)工作小組標(biāo)準(zhǔn)[5],1期25例,2期20例,3期24例。排除標(biāo)準(zhǔn):(1)年齡<18歲;(2)有慢性腎臟病史;(3)合并免疫缺陷性疾病、惡性腫瘤。
1.2方法
1.2.1臨床資料測(cè)量患者身高、體質(zhì)量,計(jì)算體質(zhì)指數(shù)(BMI)。檢測(cè)血清肌酐(Scr)水平,根據(jù)腎臟病飲食修正公式(MDRD)估算腎小球?yàn)V過(guò)率(eGFR),eGFR=186-1.154×Scr×年齡-0.203(女性則×0.742),記錄高血壓史、糖尿病史、細(xì)菌培養(yǎng)、功能衰竭臟器數(shù)及腎功能轉(zhuǎn)歸等臨床資料。
1.2.3治療患者在治療原發(fā)病基礎(chǔ)上予抗感染、液體復(fù)蘇、控制血糖、營(yíng)養(yǎng)支持等綜合對(duì)癥治療,出現(xiàn)呼吸衰竭者予機(jī)械通氣治療,出現(xiàn)難治性高血鉀癥、Scr>3 mg/dl和/或尿素氮>100 mg/dl、尿量減少導(dǎo)致的液體超負(fù)荷中的1項(xiàng)及以上者予血液凈化治療。
1.2.4腎功能臨床轉(zhuǎn)歸的判定患者入組后28 d進(jìn)行腎功能轉(zhuǎn)歸的判斷,eGFR正常判定為腎功能完全恢復(fù),eGFR持久下降但不需腎臟替代治療判定為腎功能部分恢復(fù),eGFR持久下降且需長(zhǎng)期腎臟替代治療判定為需依賴透析。根據(jù)腎功能臨床轉(zhuǎn)歸情況將患者分為腎功能完全恢復(fù)組(18例)、腎功能部分恢復(fù)組(38例)、依賴透析組(4例)和死亡組(9例)。

【Abstract】ObjectiveTo investigate the value ofT cell-iATP level in the prediction of the prognosis of sepsis patients complicated with acute kidney injury (AKI).MethodsFrom July 2013 to December 2014,a total of 69 sepsis inpatients complicated with AKI in the ICU,the Department of Infectious Disease and Nephrology in Lishui Center Hosipital were enrolled in this prospective study.The levels ofT cell-iATP at 0 h,48 h and 96 h after onset of SIAKI were detected.According to the prognosis of acute kidney injury (AKI),the subjects were divided into four groups:complete renal recovery group(18 cases),partial renal recovery group(38 cases),dialysis dependency group(4 cases) and death group (9 cases).ResultsThe four groups were significantly different in estimated glomerular filtation rate(eGFR),the number of visceral organs with function failure,and numbers of patient in each stage of AKI and the levelsT cell-iATP at 0 and 48 h (P<0.05).Multivariable Logistic regression analysis indicated that eGFR,the number of visceral organ with function failure and the levels ofT cell-iATP(48 h)were influencing factors for the complete recovery and partial recovery of renal function (P<0.05),compared with unfavorable prognosis (dialysis dependency or death).ROC curve analysis showed that the AUC ofT cell-iATP(48 h) predicting the prognosis of sepsis patients complicated with AKI was 0.926(P<0.01),with a sensitivity and a specificity as 92.3% and 87.5% respectively at a critical point of 344.2 μg/L forT cell-iATP(48 h) level.ConclusionSepsis patients with lowerT cell-iATP level have better recovery of renal function,andT cell-iATP level of patients with early-stage sepsis may serve as a predictor for the renal function outcome.
