妊娠期肝内胆汁淤积症(ICP)是妊娠中、晚期特发性肝脏疾病。由于血清胆汁酸升高,在临床上表现为以皮肤瘙痒和黄疸为特征,主要危害胎儿,出现胎儿窘迫、死胎、早产及其他新生儿并发症。ICP的病因和发病机制尚不明确。本文从遗传、激素和环境因素方面探讨了ICP的发病机制,通过胆汁酸对胎儿的影响,了解其对胎儿危害的机制,为临床上治疗ICP奠定基础。 相似文献

目的 探讨妊娠期肝内胆汁淤积症(ICP)孕妇发生胎儿死亡的临床特点、实验室指标及胎儿监护手段.方法 对1999年1月至2010年12月浙江大学医学院附属妇产科医院收治的发生死胎的21例ICP孕妇的临床资料进行回顾性分析.结果 (1)21例ICP孕妇的平均年龄(30.2±4.6)岁,其中>35岁者4例;经产妇6例,1例2年前因ICP发生死胎而引产1次;20例单胎妊娠,1例双胎妊娠.(2)21例ICP孕妇的死胎均发生在孕晚期,胎儿死亡的孕周为29~41周,平均(33.8±4.2)周.12例发生在孕29~37周,9例发生在孕37周后.9例为门诊B超检查时确诊胎死宫内;9例因诊断ICP入院治疗期间发生胎心消失;2例临产后胎心消失;1例胎心监护提示V型减速,拟行急诊刮宫产术于麻醉期间胎心消失.在所有ICP孕妇中围产儿死亡率为0.148%(21/14 184).(3)21例ICP孕妇均有皮肤瘙痒,其中11例有全身皮肤瘙痒.10例在发生死胎前自觉胎动减少或消失.21例ICP孕妇血清甘胆酸水平均升高,其中21.49~64.48 μmol/L 11例,t≥64.48 μmol/L 10例.血清总胆汁酸水平升高16例(另5例未检查),最高达270μmoL/L.血清丙氨酸氨基转移酶和天冬氨酸氨基转移酶水平升高14例,总胆红素>21μmol/L 7例,直接胆红素升高12例.21例ICP孕妇中,重度15例,轻度6例.(4)9例孕妇门诊即确诊宫内死胎未做胎心监护,其余12例住院检查结果 为:胎心监护结果 可疑2例,无应激试验(NST)提示胎心轻度V型减速1例,B超提示脐动脉舒张期血流缺如3例,胎儿生物物理指标评分低值1例.(5)21例ICP孕妇均经阴道分娩.6例为自然宫缩娩出死胎,其余15例予米非司酮配合依沙吖啶羊膜腔注射或缩宫素引产,14例在48 h内成功娩出死胎,仅1例追加地诺前列酮栓后引产成功.所有死胎外观无异常,脐带长度均在正常范围,有4例脐带绕颈或绕体.胎盘胎膜外观无异常,18例羊水Ⅲ度胎粪污染,2例合并羊水过少.10例行死胎及胎盘病理检查,其中1例合并多发畸形,其余死胎病理检查未见明显异常,10例胎盘病理检查均有绒毛膜周围或底蜕膜、大血管周围的纤维蛋白沉积,同时伴有钙化、退行性变、红色梗死及局灶性合体细胞结节增多.结论 ICP孕妇发生死胎的孕周常在孕晚期,时间常在正常宫缩后,ICP重度可能是发生死胎的关键因素;尚无有效的胎儿监护指标可预测死胎的发生.因此,应综合评估病情,加强胎儿监护,适时终止妊娠.Abstract: Objective To investigate the clinical features,critical laboratory parameters,and fetal monitoring methods in intrahepatic cholestasis of pregnancy(ICP).Methods A retrospective analysis of 21 cases of ICP suffered with fetal death in Women's hospital.School of Medicine.Zhejiang University from January 1999 to December 2010 were discussed.Results(1)The average age of ICP patients suffered with fetal death were(30.2±4.6)years old.Among them,4 cases were older than 35 years,six cases were multipara.oneo of them suffered stillbirth 2 year before.Twenty cases were singleton pregnancies and 1 cage was twin pregnancy.(2)All 21 cases of fetal death occurred in the third trimester,12 cases occurred before 37 weeks,9 cases after 37 weeks.Nine cases were diagnosed by ultrasound in outpatient clinics,fetal heart beat disappeared in 9 patients after admission because of ICP, two disappeared after labor, one during anesthesia before emergent surgery. Perinatal mortality rate of ICP was 0. 148% (21/14 184), and fetal death occurred from 29 to 41 weeks with an average gestational age of ( 33.8 ± 4. 2 ) weeks, ( 3 ) Puritus occurred in all 21 cases while 11 of them had pruritus all over the body. Ten pregnant women felt the fetal movement decreased or disappeared before diagnosis of fetal death. The glycocholic acid levels increased in all of the 21 cases. Among them, glycocholic acid levels in 11 cases were (21.49 -64. 48) μmol/L, while in 10 cases were ≥64. 48 μmol/L Serum bile acid levels elevated in 16 cases which had been analyzed ( the other 5 cases had not been checked ), and the highest level reached 270 μmol/L Serum alanine aminotransferase and aspartate aminotransferase were increased in 14 cases. Seven cases had their total bilirubin >21 μmoL/L, and 12 cases had their direct bilirubin levels significantly elevated. Among the 21 cases of ICP, 15 cases were in severe status, while the other 6 cases were mild. (4) Nine patients had no antepartum surveillance since fetal death were diagnosed before admission. The results of antepartum surveillance were as follows: 2 cases had nonreassuring nonstress test (NST), one had mild "V" type deceleration. Absence of diastolic flow in umbilical artery were found in 3 cases, and low fetal biophysical score was got in one case. ( 5 ) All 21 patients had vaginal delivery. Six of them delivered after natural contraction, and the remaining 14 cases delivered after oral intake of mifepristone and amniotic injection of ethacridine, or oxytocin induced labor within 48 hours, only one case delivered after additional dinoprostone suppositories. The appearance of fetus, placentas and membranes were normal, the lengths of umbilical cord were average. Four cases were found with cords binding the necks or the bodies. Eighteen cases had grade Ⅲ amniotic fluid with meconium-stained, and 2 cases complicated by oligohydramnios. Ten cases had their fetuses and placentas examined by pathologist. Among them, one case had multiple malformations, no more obvious pathological abnormalities were found in other fetuses. Pathologic examination showed that fibrin deposited around chorion and deciduas basalis, large vessels accompanied by calcification, degeneration,hemorrhagic infarction, and increased focal syncytial nodules could be seen in all of the ten placentas. Conclusions Fetal death in pregnant women with ICP of ten occurs after the contractions, Severe ICP may be a key factor that involved in the occurrence of fetal death. Up to now, there is no valid indicators in fetal monitoring, which can predict fetal death. Extensive assessment of the severity and careful antepartum surveillance should be achieved before timely termination of pregnancy. 相似文献

近20年妊娠肝内胆汁瘀积症诊断及处理的变化 总被引:15,自引:0,他引:15
目的探讨近20年妊娠肝内胆汁瘀积症(ICP)发病率及诊断、处理方法的变化.方法按每5年为1个时间段回顾性分析我院1980年1月至1999年12月间240例ICP的诊治情况,结果①ICP的发病率由1980年至1984年的0.27%上升为1995年至1999年的5.37%(P<0.05).②诊断技术的改进,诊断规范化,特别是胆酸升高为ICP的特异性生化指标,使ICP确诊时间提前,当胆酸升高>40 mg/L时,羊水粪染率明显增加(P<0.01).③虽ICP发病率明显上升,但胎儿宫内窘迫发生率并未随之增加(P>0.05).④分娩方式由阴道分娩逐渐过渡到以剖宫产结束分娩(P<0.01).虽剖宫产率明显增高,但产后出血发生率并未增加,新生儿窒息率明显下降.结论ICP发生率增高,诊断规范化,血清胆酸检查辅以肝功能检查,缩短了确诊时间,剖宫产术是目前ICP终止妊娠的主要手段. 相似文献

OBJECTIVE: To explore the effect of deficiency of blood selenium and placental selenium on the damage of histomorphology of the placentas in ICP. METHODS: We measured the selenium concentration by a catalytic polorographic method in blood and placenta and glutathione peroxidase (GSH-Px) activity by a 5,5'-dithionbis (2-nitrobenzoic acid) direct method in blood in 30 women with ICP (ICP group) and 30 normal pregnant women (control group). Furthermore, the features of the placentas (10 from control group and 10 from ICP group) pathologic changes were observed microscopically. RESULTS: (1) The selenium concentrations in blood (0.0389 +/- 0.0090) mg/L and placenta (0.3770 +/- 0.0964) mg/kg and the activity of GSH-Px (59.31 +/- 11.42) U in ICP group were found to be significantly lower than those in blood (0.0477 +/- 0.0094) mg/L and placenta (0.4554 +/- 0.0626) mg/kg and the activity of GSH-Px (68.48 +/- 10.47) U in control group, respectively (P < 0.002). (2) The activity of GSH-Px had a significant positive correlation with selenium concentration in blood in ICP group (r = 0.05498, P < 0.001) and in control group (r = 0.06234, P < 0.001). There was a positive correlation between blood and placental selenium concentrations in ICP group (r = 0.6473, P < 0.001). On the other hand, there was not correlation in women with normal pregnancies. (3) Placentas obtained from women with ICP had swelling and fibrinoid necrosis of villi, increasing number of syncytial sprouts, thickening of vasculo-syncytial membrane (VSM) and decreasing size of the intervillous space under light microscopy. Placentas from control group did not show the pathologic changes as mentioned above. CONCLUSIONS: As selenium constitutes the active part of GSH-Px, these results suggest that the placental selenium deficiency may lead to reduced placental GSH-Px activity and the antioxidative defence may have been defective which may be associated with the damage of histomorphology of the placentas in ICP. 相似文献
