[摘要] 目的 探讨妊娠高血压综合征患者血清胱抑素C(Cys C)的水平变化及其他肾功能指标的临床意义。 方法 选择2011年1月~2012年10月鄂州市妇幼保健院健康妊娠妇女113例,分为早期妊娠组(35例)、中期妊娠组(40例)和晚期妊娠组(38例),另选择住院妊娠高血压综合征患者42例为妊娠高血压组,同时选择健康未孕体检妇女32例为对照组。对5组均进行血清Cys C、尿素氮(BUN)及肌酐(SCr)检测。 结果 与对照组[(0.59±0.15)mg/L]比较,血清Cys C水平在早期妊娠组[(0.62±0.09)mg/L]、中期妊娠组[(0.75±0.13)mg/L]升高不明显(P > 0.05),晚期妊娠组[(1.05±0.32)mg/L]、妊娠高血压组[(1.25±0.28)mg/L]明显升高(均P < 0.05)。各组BUN、SCr升高均不明显(P > 0.05)。妊娠高血压组Cys C与BUN、SCr无相关性(r = 0.25、0.16,P > 0.05)。 结论 妊娠高血压综合征患者Cys C能提示早期肾脏损伤,及时诊断,改善妊娠预后。

[Abstract] Objective To investigate clinical effect of serum cystatin C (Cys C) and other renal indexes in patients with pregnancy hypertension syndrome. Methods From January 2011 to October 2012, in the Maternal and Child Health Care Hospital of Ezhou City, 113 normal pregnancy women were selected and divided into early pregnany group (35 cases), middle pregnany group (40 cases) and late pregnancy group (38 cases). 42 patients with pregnancy hypertension syndrome were selected as pregnancy hypertension syndrome group, and 32 healthy women without pregnancy were selected as control group. The Cys C, BUN and SCr of five groups were detected. Results Compared with control group [(0.59±0.15) mg/L], the Cys C levels of early pregnany group [(0.62±0.09) mg/L], middle pregnany group [(0.75±0.13) mg/L] were higher ,but the differences were not statistically significant (P > 0.05), those of normal late pregnancy group [(1.05±0.32) mg/L] and pregnancy hypertension syndrome group [(1.25±0.28) mg/L] were significantly higher (P < 0.05). The levels of BUN, SCr of five groups were compared, the differences were not statistically significant (P > 0.05). There was no correlation between BUN, SCr and Cys C in pregnancy hypertension syndrome group (r = 0.25, 0.16, P > 0.05). Conclusion The serum Cys C of patients with pregnancy hypertension syndrome can indicate early renal damage, help to make timely diagnosis, and improve pregnancy outcome.

妊娠高血压综合征属于产科常见病、多发病,在全部妊娠产妇中占到5%~10%。肾脏损害也是该病最常见的病理改变,常造成不同程度的肾功能改变,可出现蛋白尿,甚至肾功能不全,是引起流产、早产、甚至死胎的原因之一,所以对妊娠期肾功能的变化要引起足够的重视。研究显示胱抑素C(Cys C)较血清肌酐(SCr)有更高的灵敏度和特异性,是反映肾小球滤过率(GFR)较为理想的内源性指标[1],也是提示肾脏早期损害指标[2],临床上广泛应用于各类患者肾损伤的早期诊断。本文通过比较正常妊娠与妊娠高血压综合征孕妇的血清Cys C和其他肾功能相关指标变化,评价其对妊娠高血压综合征早期肾损害的诊断价值。
