目的:擬通過(guò)檢測(cè)慢性腎臟病患者血清Hs-CRP及肌酐、尿素氮,初步探討慢性腎臟病患者微炎癥反應(yīng)狀態(tài)與腎功能的相關(guān)性。方法:我院住院治療且診斷明確的1-4期CKD 患者100 例、在體檢中心行健康體檢者20 例( 正常組) 作為研究對(duì)象。收集受試對(duì)象的外周血標(biāo)本,檢測(cè)Hs-CRP及肌酐、尿素氮。結(jié)果:兩組患者年齡無(wú)明顯差異,兩組間BUN,Cr, Hs-CRP有顯著性差異,CKD組BUN,Cr,CRP明顯高于正常對(duì)照組(P<0.05)。結(jié)論:Hs-CRP作為炎癥反應(yīng)的重要細(xì)胞因子, 可能參與了慢性腎臟病患者的微炎癥反應(yīng), 微炎癥因子在慢性腎臟病發(fā)生及病情進(jìn)展中發(fā)揮重要作用。
微炎癥反應(yīng)狀態(tài),慢性腎臟病,腎功能
慢性腎臟病在全球范圍內(nèi)的患病率為 10.2%-13.0%。在我國(guó),CKD的發(fā)病率每年以7%的速度上升。近年來(lái)研究證實(shí),微炎癥狀態(tài)是慢性腎臟病患者動(dòng)脈硬化、心血管疾病(CVD) 并發(fā)癥的關(guān)鍵因素。CRP等炎癥細(xì)胞因子、急性時(shí)相蛋白等釋放為中心的緩慢發(fā)生和持續(xù)存在的輕微炎性反應(yīng), 是通過(guò)實(shí)驗(yàn)室檢測(cè)才被發(fā)現(xiàn)的特殊狀態(tài), 即“微炎癥反應(yīng)狀態(tài)”。超敏 C反應(yīng)蛋白是檢測(cè)慢性腎功能衰竭患者微炎癥狀態(tài)的重要指標(biāo)[1-3]。因此本課題擬通過(guò)對(duì)慢性腎臟病患者血清炎性因子Hs-CRP和肌酐、尿素氮等聯(lián)合檢測(cè),初步探討慢性腎臟病患者微炎癥反應(yīng)狀態(tài)與腎功能的相關(guān)性。
1.1 一般資料:選取在我科住院治療且診斷明確的1-4期CKD患者100 例、在體檢中心行健康體檢者20 例( 正常組) 作為研究對(duì)象。CKD 的診斷及分期標(biāo)準(zhǔn)參照第7 版內(nèi)科學(xué),患者腎小球?yàn)V過(guò)率( GFR)的計(jì)算采用中國(guó)人簡(jiǎn)化MDRM 公式。
1.2 采集外周血樣本及相應(yīng)指標(biāo)的檢測(cè):患者入院后第二天采取靜脈血,-80度冰箱保存。分別檢測(cè)Hs-CRP、肌酐、尿素氮等指標(biāo)。
應(yīng)用SPSS 17. 0統(tǒng)計(jì)軟件進(jìn)行統(tǒng)計(jì)。數(shù)據(jù)采用均數(shù)±標(biāo)準(zhǔn)差表示, 組間比較采用單因素方差分析。以P<0.05表示有統(tǒng)計(jì)學(xué)意義。
100例CKD患者男性57例,女性43例,正常對(duì)照組男女各10例。兩組患者年齡無(wú)明顯差異,CKD組BUN,Cr,Hs-CRP明顯高于正常對(duì)照組,兩組間比較有顯著性差異(P<0.05)。詳見(jiàn)表1。

臨床上關(guān)于 CRP 的研究已經(jīng)具有 70 多年的歷史,傳統(tǒng)的觀(guān)點(diǎn)認(rèn)為CRP 是一種非特異的炎癥標(biāo)志物, 但是經(jīng)過(guò)近十幾年的研究,CRP 本身也是一種促炎癥介質(zhì)并主動(dòng)參與炎癥過(guò)程本身。本研究結(jié)果表明兩組間BUN,Cr,Hs-CRP有顯著差異,CKD組BUN,Cr,CRP明顯高于正常對(duì)照組。研究表明慢性腎臟病患者普遍存在微炎癥狀態(tài), 即使在腎臟損害早期, 炎癥介質(zhì)也已明顯增高。微炎癥狀態(tài)標(biāo)志物從一定程度上可以較好地反應(yīng)出慢性腎臟病患者的微炎癥狀態(tài)。Hs-CRP作為炎癥反應(yīng)的重要細(xì)胞因子, 可能參與了慢性腎臟病患者的微炎癥反應(yīng), 微炎癥因子在慢性腎臟病發(fā)生及病情進(jìn)展中發(fā)揮重要作用。

Objective: To study the correlation between serum Hs-CRP, creatinine and urea nitrogen in patients with chronic kidney disease, and to explore the relationship between the micro inflammatory reaction and renal function in patients with chronic kidney disease.Methods: in our hospital, 100 cases of CKD patients with clear diagnosis of 1-4 and 20 cases of healthy physical examination in the physical examination center were used as the research objects. Peripheral blood samples were collected to detect Hs-CRP, creatinine and urea nitrogen.Results: there were no significant differences in age between the two groups, BUN, Cr, Hs-CRP, CKD, BUN, Cr, CRP in the two groups was significantly higher than that in the control group (P< 0.05).Conclusion: Hs-CRP is an important cytokine in the inflammatory response, which may play an important role in the occurrence and progression of chronic kidney disease in patients with chronic kidney disease.
