摘要 目的分析异常凝血酶原(PIVKA-Ⅱ)联合唾液酸(SA)诊断慢性肾功能不全(CRF)的临床价值。方法选择2017年3月至2018年3月该院诊治的70例CRF患者作为CRF组,另选择同期体检健康者50例作为对照组。根据慢性肾脏病(CKD)标准将CRF患者分为CKD-1至CKD-5共5个亚组。测定血清PIVKA-Ⅱ、SA水平,观察PIVKA-Ⅱ、SA单独及联合检测诊断CRF的临床价值。结果CRF组患者血清PIVKA-Ⅱ、SA水平分别为(27.45±4.43)、(78.79±11.37)mAU/mL,明显高于对照组[(22.52±3.26)、(54.35±8.84)mAU/mL],差异有统计学意义(P<0.05)。CRF患者CKD-1期与CKD-2期的血清PIVKA-Ⅱ、SA水平与对照组比较,差异无统计学意义(P>0.05),CKD-3期、CKD-4期、CKD-5期患者血清PIVKA-Ⅱ、SA水平较对照组均明显升高(P<0.05)。PIVKA-Ⅱ单独检测CRF的灵敏度、特异度为48.57%、91.43%;SA单独检测CRF的灵敏度、特异度为68.57%、92.85%;PIVKA-Ⅱ联合SA检测CRF的灵敏度、特异度为82.65%、97.15%。结论PIVKA-Ⅱ联合SA检测能明显提高检测灵敏度、特异度,极大提升诊断CRF的准确率。
