孕妇血清中可溶性endoglin水平变化与重度子痫前期及子痫患者发病的关系

摘要

目的 探讨孕妇血清中可溶性endoglin水平变化与重度子痫前期及子痫发病的关系.方法 2005年12月至2007年12月在北京大学第一医院分娩的重度子痫前期孕妇42例和子痫孕妇4例为研究组,孕(35±4)周,年龄(29.3±5.7)岁,体系指数(30.1±4.1)ks/m2;其中早发型子痫前期25例,晚发型子痫前期21例,并发胎儿生长受限(FGa)8例,并发溶血、肝酶升高和低血小板计数(HELLP)综合征5例.选择同期妊娠结局正常的29例孕妇为对照组,孕(33±4)周,年龄(30.7±3.4)岁,体重指数(27.2±2.2)ks/m2.采用酶联免疫吸附试验检测两组孕妇血清中可溶性endoglin水平,分析血清中可溶性endoglin水平变化与孕周的相关性.结果 (1)对照组孕妇在27～37孕周血清中可溶性endoglin水平与孕周有正相关关系(r=0.79,P<0.05),研究组无明显相关性(r=0.31,P>0.05).(2)研究组孕妇血清中可溶性endoglin水平为(14.2 ±5.6) μg/L,高于对照组的(10.9±4.2)μg/L,两组比较,差异有统计学意义(P<0.01).(3)研究组中早发型子痫前期孕妇血清中可溶性endoglin水平为(14.3±5.7)μg/L,晚发型子痫前期孕妇为(13.6±5.0)μg/L,两者比较,差异无统计学意义(P>0.05).(4)并发HELLP综合征孕妇血清中可溶性endoglin水平为(10.1±2.9)μg/L,无HELLP孕妇为(14.4±5.4)μg/L,两者比较,差异无统计学意义(P>0.05).(5)并发FGR孕妇血清中可溶性endoglin水平为(17.3±6.1)μg/L,无FGR孕妇为(13.0±4.8)μg/L,两者比较.差异有统计学意义(P<0.05).结论 孕妇血清中可溶性endoglin水平升高,可能与重度子痫前期及子痈、FGR的发病有关,但与发病时间无明显关系.%Objective To discuss the serum endoglin expression in severe pre-eclampsia and eclampsia women and their relationships. Methods Forty-two severe pre-eclamptic patients and 4 eclamptic patients in Peking University First Hospital from Dec. 2005 to Dec. 2007 were enrolled in the study group, with the mean gestational week of 35 ± 4, the mean age of 29.3 ± 5.7 and the mean BMI (30.1 ± 4.1 ) kg/ m2. This group included 25 cases of early onset pre-eclampsia, 21 cases of late onset pre-eclampsia, 8 cases of fetal growth restriction and 5 cases of HELLP syndrome. The control group included 29 cases of normal pregnant women during the same period, with the mean gestational week of 33±4, the mean age of 30.7± 3.4 and the mean BMI(27.2±2. 2) kg/m2. Peripheral serum endoglin was determined by ELISA in these two groups. Results (1)There is positive correlation between serum soluble endoglin level and the gestational weeks during 27 to 37 gestational weeks in the control group (r=0.79, P<0.05), but there is no distinct relationship in the study group (r=0.31, P>0.05). (2) Serum endoglin level of severe pre-eclampsia group was higher than the normal group [(14.2±5.6)μg/L vs. ( 10.9 ± 4.2 ) μg/L, P<0.05]. (3) Serum endoglin level of early onset group did not differ from late onset group [(14.3±5.7)μg/L vs. (13.6±5.0)μg/L, P >0.05]. (4) No difference of serum endoglin between HELLP group and non-HELLP group was found [(10.1±2.9) μg/L vs. ( 14.4±5.4) μg/L, P>0.05 ]. (5) Serum endoglin level of FGR sub group was higher than non-FGR sub group [(17.3±6.1) μg/L vs. (13.0±4.8) μg/L, P < 0.05] in the stady group. Conclusion The elevated peripheral serum endoglin level may contributes to the pathogenesis of severe pre-eclampsia and FGR, but not the week of the onset of the disease.
