【摘要】 目的:探討血清胱抑素C(Cys-C)和視黃醇結合蛋白(RBP)聯合檢測在慢性腎臟病(CKD)早期腎功能損傷中的診斷價值。方法:將筆者所在醫院2018年1-12月收治的52例CKD早期腎功能損傷患者設為觀察組,將同期在筆者所在醫院體檢中心進行體檢的健康者52例設為對照組,研究血清Cys-C、RBP診斷價值。結果:觀察組血清Cys-C、RBP水平高于對照組(P<0.05);CKD早期腎功能損傷患者中聯合檢測陽性率高于單獨檢測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(P<0.05)。結論:血清Cys-C聯合RBP在CKD早期腎功能損傷患者的診斷應用中,其陽性檢出率高于任一單項檢測,二者具有相關性,具有臨床診斷價值。

[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.
慢性腎臟病(CKD)是指各種原因引起的慢性腎臟結構及功能障礙,且腎功能損傷病史超過3個月,內容包括腎臟不正常的病理損傷、血液或尿液檢查成分異常等,患者多表現為食欲不振、惡心、嘔吐等[1]。對CKD早期腎功能損傷的發現和干預,可以降低患者的多種并發癥發生率,提高患者的生存率[2]。目前臨床對CKD早期腎功能損傷的診斷指標雖然多,但是對CKD早期腎功能損害指標的多數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)和視黃醇結合蛋白(RBP)檢測應用于CKD早期腎功能損傷的診斷中,并分析其臨床應用價值,現報告如下。
1 資料與方法
1.1 一般資料
納入標準:(1)臨床或個人資料完整;(2)無嚴重心腦血管疾病;(3)認知功能正常,無精神類障礙。排除標準:(1)糖尿病、高血壓等慢性疾病者;(2)嚴重肝臟類疾病;(3)急性感染者。參與此次研究人員均為自愿,且簽署知情同意書。選取筆者所在醫院2018年1-12月收治的52例CKD早期腎功能損傷患者設為觀察組,其中,男30例,女22例;年齡24~72歲,平均(50.6±2.8)歲,均符合CKD早期腎功能損傷的臨床診斷標準及影像學檢查結果。選取同期在筆者所在醫院體檢中心進行體檢的健康者52例設為對照組,其中,男32例,女20例;年齡23~70(50.2±3.1)歲。兩組性別、年齡比較,差異無統計學意義(P>0.05),有可比性。
1.2 檢測方法
采集受檢者晨起空腹靜脈血3 ml,分離血清,保存溫度
-20 ℃;使用全自動生化分析儀(北京普朗新技術有限公司,型號:SMT100)進行檢測:采用血清Cys-C檢測試劑盒(上海酶聯生物科技有限公司)檢測血清Cys-C,正常參考區間為0.56~1.22 mg/L;采用RBP檢測試劑盒(上海通蔚科技有限公司)檢測RBP,正常參考區間為25~70 mg/L。檢測方法均為免疫比濁法。
