【摘要】 目的:探討血清胱抑素C(Cys-C)和視黃醇結(jié)合蛋白(RBP)聯(lián)合檢測(cè)在慢性腎臟?。–KD)早期腎功能損傷中的診斷價(jià)值。方法:將筆者所在醫(yī)院2018年1-12月收治的52例CKD早期腎功能損傷患者設(shè)為觀察組,將同期在筆者所在醫(yī)院體檢中心進(jìn)行體檢的健康者52例設(shè)為對(duì)照組,研究血清Cys-C、RBP診斷價(jià)值。結(jié)果:觀察組血清Cys-C、RBP水平高于對(duì)照組(P<0.05);CKD早期腎功能損傷患者中聯(lián)合檢測(cè)陽(yáng)性率高于單獨(dú)檢測(cè)Cys-C、RBP(P<0.05);且CKD早期腎功能損傷患者血清Cys-C與RBP水平呈正相關(guān)(P<0.05)。結(jié)論:血清Cys-C聯(lián)合RBP在CKD早期腎功能損傷患者的診斷應(yīng)用中,其陽(yáng)性檢出率高于任一單項(xiàng)檢測(cè),二者具有相關(guān)性,具有臨床診斷價(jià)值。

[Abstract] Objective: To investigate the diagnostic value of serum cystatin C (Cys-c) and retinol binding protein (RBP) in early renal injury in chronic kidney disease (CKD). Method: A total of 52 patients with early renal impairment of CKD admitted to our hospital from January to December 2018 were set as the observation group, and 52 healthy patients who underwent physical examination in the physical examination center of our hospital during the same period were set as the control group. The diagnostic value of serum Cys-c and RBP levels were studied. Result: Serum levels of Cys-c and RBP were higher in the observation group than those in the control group (P<0.05). The positive rate of combined detection in patients with early renal function injury of CKD was higher than the positive rate of single detection of Cys-C or RBP (P<0.05). Moreover, serum Cys-c was positively correlated with RBP level in patients with early renal impairment of CKD (P<0.05). Conclusion: In the diagnosis and application of serum Cys-c combined with RBP in patients with early renal function injury of CKD, the positive detection rate is higher than that of any single test. And they are correlated, which has clinical diagnostic value.
慢性腎臟?。–KD)是指各種原因引起的慢性腎臟結(jié)構(gòu)及功能障礙,且腎功能損傷病史超過(guò)3個(gè)月,內(nèi)容包括腎臟不正常的病理?yè)p傷、血液或尿液檢查成分異常等,患者多表現(xiàn)為食欲不振、惡心、嘔吐等[1]。對(duì)CKD早期腎功能損傷的發(fā)現(xiàn)和干預(yù),可以降低患者的多種并發(fā)癥發(fā)生率,提高患者的生存率[2]。目前臨床對(duì)CKD早期腎功能損傷的診斷指標(biāo)雖然多,但是對(duì)CKD早期腎功能損害指標(biāo)的多數(shù)敏感性及檢出率仍有不足[3]。因此,本文將血清胱抑素C(Cys-C)和視黃醇結(jié)合蛋白(RBP)檢測(cè)應(yīng)用于CKD早期腎功能損傷的診斷中,并分析其臨床應(yīng)用價(jià)值,現(xiàn)報(bào)告如下。
