【摘要】:背景 隨著醫(yī)療保障制度的完善和血液凈化技術(shù)的進(jìn)展,更多終末期腎臟病(End-stage renal disease,ESRD)患者可以接受腎臟替代治療,并可以依靠血液透析長期維持生命,但隨之而來的各種并發(fā)癥,尤其是心腦血管并發(fā)癥,卻成為了他們死亡的首要原因。在尿毒癥患者中,導(dǎo)致心血管疾病發(fā)病率升高的原因除了傳統(tǒng)的危險因素外,還包括:容量超負(fù)荷導(dǎo)致的高血壓和左心室肥厚、尿毒癥毒素、鈣磷代謝紊亂導(dǎo)致的血管鈣化、慢性炎癥狀態(tài)等。 由于ESRD患者腎功能的喪失和替代治療的間斷性,他們中大部分人都存在容量超負(fù)荷,所以如何降低尿毒癥患者心血管疾病的發(fā)病率和死亡率,控制其容量平衡使干體重達(dá)標(biāo)是關(guān)鍵因素。如果干體重設(shè)定過高,就有可能導(dǎo)致透析患者出現(xiàn)高血壓、充血性心力衰竭、左心室肥厚、體腔積液和水腫等臨床表現(xiàn),增加患者心腦血管疾病的發(fā)生率。如果干體重設(shè)定過低,會使患者出現(xiàn)透析相關(guān)低血壓,嚴(yán)重的還會導(dǎo)致休克、心肌梗塞、短暫性腦缺血的發(fā)生,影響透析患者的依從性。因此,如何準(zhǔn)確的評估尿毒癥患者的干體重成為了臨床醫(yī)生所面臨的難題。 腦鈉肽(Brain natriuretic peptide,BNP)是在心室壁受到牽拉刺激時由心肌細(xì)胞產(chǎn)生的一種多肽。在以往的研究中證實(shí),BNP或NT-proBNP(N-terminalpro-brain natriuretic peptide)的水平與慢性腎臟。–hronic kidney disease,CKD)患者的左心室肥厚和左室舒張功能紊亂有較強(qiáng)的相關(guān)性,一般用其來預(yù)測正常人群或CKD患者心血管疾病的發(fā)病情況。最近有學(xué)者提出,BNP或NT-proBNP水平可能與透析患者的細(xì)胞外液量相關(guān),但在排除了存在左心室肥厚或收縮功能障礙的患者后,上述假設(shè)卻并沒有得到證實(shí),所以BNP或NT-proBNP能否用來評估透析患者的容量狀況存在著爭議。生物電阻抗技術(shù)作為評估透析患者干體重的一種方法,已經(jīng)經(jīng)過同位素示蹤法的驗(yàn)證,本研究中我們選擇126例維持性血液透析(Maintenance hemodialysis,MHD)患者作為研究對象,應(yīng)用生物電阻抗技術(shù)作為標(biāo)準(zhǔn),分析NT-proBNP在非顯性水腫MHD患者容量狀態(tài)評價中的意義。目的 1.應(yīng)用生物電阻抗技術(shù),了解非顯性水腫MHD患者的容量狀況; 2.通過用生物電阻抗技術(shù)作為標(biāo)準(zhǔn),來探討NT-proBNP在非顯性水腫MHD患者容量狀態(tài)評價中的意義。方法 研究對象:選擇2013年6月到2013年10月于鄭州大學(xué)第一附屬醫(yī)院血液凈化中心就診的維持性血液透析患者作為研究對象,根據(jù)篩選條件,,共入選126例患者,其中男性62例,女性64例。 實(shí)驗(yàn)分組:選擇周中短透析間期時,透析前采用人體成分分析儀(Bodycomposition monitor,BCM)評估透析患者容量負(fù)荷情況,獲得overhydration(OH)值,根據(jù)OH值(OH值=OH值-間期體重增加量)進(jìn)行分組,以O(shè)H值≤1L為干體重達(dá)標(biāo)組, OH值1L為容量超負(fù)荷組。 實(shí)驗(yàn)內(nèi)容:0月時,于透析前采用人體成分分析儀評估透析患者的容量狀況,同時測量透前NT-proBNP的濃度,并搜集其臨床資料,依據(jù)上述分組標(biāo)準(zhǔn),分別對兩組的NT-proBNP水平進(jìn)行比較,并分析其與OH值的相關(guān)性。在3月內(nèi),對容量超負(fù)荷組患者的干體重進(jìn)行調(diào)整,3月后再次測量這部分研究對象的OH值和NT-proBNP濃度,仍然依據(jù)上述分組標(biāo)準(zhǔn)進(jìn)行分組,比較兩組的NT-proBNP水平,并分析其與OH值的相關(guān)性,同時與0月時的OH值和NT-proBNP濃度進(jìn)行比較。最后,以O(shè)H值≤1L作為透析患者容量負(fù)荷控制合理的標(biāo)準(zhǔn),判斷NT-proBNP對非顯性水腫MHD患者的診斷效能。結(jié)果 1.0月時,126例患者的基線資料:干體重達(dá)標(biāo)組患者為36例,容量超負(fù)荷組患者為90例,干體重達(dá)標(biāo)率為28.57%。容量超負(fù)荷組患者的收縮壓要高于干體重達(dá)標(biāo)組(152.5±14.86mmHg VS136.4±12.53mmHg,P0.001),同時其舒張壓也顯著高于干體重達(dá)標(biāo)組(87.1±6.31mmHg VS76.3±7.64mmHg,P0.001),差異均有統(tǒng)計學(xué)意義。而性別、年齡、BMI、體重間的差異均無統(tǒng)計學(xué)意義。 2.0月時,所有研究對象的血漿NT-proBNP水平均高于正常范圍(0-100pg/ml),四分位數(shù)間距為615.50-2061.75pg/ml。容量超負(fù)荷組患者的NT-proBNP水平顯著高于干體重達(dá)標(biāo)組,差異有統(tǒng)計學(xué)意義(717.00-3154.25pg/ml VS450.50-873.00pg/ml,P0.001)。相關(guān)性分析結(jié)果示:NT-proBNP與OH值呈正相關(guān)(r=0.801,P0.001)。 3.3月時,90例容量超負(fù)荷的患者,經(jīng)調(diào)整干體重后,共有41例患者干體重達(dá)標(biāo),達(dá)標(biāo)率為45.56%。90例研究對象的血漿NT-proBNP水平仍高于正常范圍(0-100pg/ml),四分位數(shù)間距為572.25-1936.75pg/ml。容量超負(fù)荷組患者的NT-proBNP水平仍顯著高于干體重達(dá)標(biāo)組,差異有統(tǒng)計學(xué)意義(982.50-2500.50pg/ml VS422.50-988.50pg/ml,P0.001)。相關(guān)性分析結(jié)果示:NT-proBNP與OH值仍呈正相關(guān)(r=0.684,P0.001)。 4.3月時,90例容量超負(fù)荷患者的OH值與NT-proBNP水平均較3個月前顯著下降,分別為1.24±0.79L VS2.06±0.83L (t=11.710, P0.001),572.25-1936.75pg/ml VS717.00-3154.25pg/ml(Z=5.627,P0.001),差異均有統(tǒng)計學(xué)意義。 5.以O(shè)H值的變化作為診斷標(biāo)準(zhǔn), OH≤1L為干體重達(dá)標(biāo)。NT-proBNP對非顯性水腫MHD患者容量狀態(tài)評價的ROC曲線下面積(AUC)為0.818(95%CI0.733-0.904,P0.001)。根據(jù)ROC曲線預(yù)測NT-proBNP對非顯性水腫MHD患者容量狀態(tài)評價的臨界點(diǎn)是962.5pg/ml,靈敏度為79.6%,特異度為73.2%。 結(jié)論 1.在非顯性水腫的MHD患者中,容量超負(fù)荷仍普遍存在; 2.NT-proBNP可以用來評估非顯性水腫MHD患者的容量狀況,幫助其調(diào)整干體重。
