妊娠合并极重度血小板减少26例临床分析

Objective To investigate the etiology and perinatal outcome of pregnancies complicated with extremely severe thrombocytopenia [ at least two times of platelets count (PLT) < 10 × 109/L during pregnancy]. Methods Clinical data, including basic information, etiology, management and outcomes of pregnant women with extremely severe thrombocytopenia, admitted to Peking University People's Hospital from January 2004 to March 2009, were retrospectively collected. The management of these cases varied according to different etiology and the symptoms: (1) PLT were maitained > 20 × 109/L and hemoglobulin> 70 g/L in those women without spontaneous bleeding; (2) PLT transfusion would be required when PLT< 10 × 109/L or bleeding occur and RBC would be supplied when hematocrit <25% and hemoglobulin <70g/L; (3) Hemoglobulin should be > 70 g/L and PLT >30 × 109/L before cesarean section or delivery;(4) Predinisone and/or intravenous immunoglobulin G (IVIG) would be given in women complicated with idiopathic thrombocytopenic purpura (ITP) when PLT < (20-30) × 109/L or bleeding. PLT would be given if all the above management were failed, or PLT < 10 × 109/L, or bleeding. Women without bleeding would be closely monitored and delivery would be planned. Results (1) Twenty-six cases were identified among 9302 deliveries during the study period (0.28%), with an average of maternal age of 29. Seventeen were diagnosed before conception and 9 during pregnancy. Among the 26 women, half received regular prenatal check in our hospital and the average gestations at diagnosis was 24 weeks and the other half without regular prenatal visits and the average gestations at diagnosis was 32 weeks. Etiology was identified in 24 out of the 26 women, including 14(54%) ITP, 5 myelodysplastic syndrome (MDS), 4 chronic aplastic anaemia(CAA) and 1 systemic lupus erythematosus (SLE). (2) Management: All of the 26 women received blood products. Among the 14 ITP cases, 6 received predinisone and IVIG and 8 only took predinisone. Nine of the 26 patients (35%) had pregnant complications, among which 6 (6/9) were preeclampsia. The overall average gestation at delivery was 36 weeks. Only 2 delivered vaginally with the average blood loss of 83 ml and 23 cesarean sections were performed with the average blood loss of 410 ml. (3) Perinatal outcomes:There were 26 perinatal babies, among which 1 died intrauterine and 25 were born alive (12 preterm infants). The average birth weight was 2877 g. Neonatal severe thrombocytopenia presented in 2 newborns whose mother complicated with ITP. Conclusions The main cause of extremely severe thrombocytopenia during pregnancy is ITP, managed mainly by predinisone and IVIG, followed by CAA and MDS, which may require supportive treatment. Pregnancy complicated with extremely severe thrombocytopenia is not an indication of termination. Better maternal and fetal outcomes can be achieved through proper treatment based on the etiology, intensive care in prevention and management of complications and cesarean section.     

妊娠期血小板减少程度对母儿结局的影响

Objective To investigate the perinatal outcomes of pregnancies complicated with varying degrees of thrombocytopenia.Methods Clinical data of 305 pregnant women with thrombocytopenia,who admitted to Peking University People's Hospital from January 1,2000 to January 31,2010 were retrospectively analyzed.The etiological diagnosis of them were gestational thrombocytopenia (GT),idiopathic thrombocytopenic purpura (ITP) or undetermined.The patients were divided into 4 groups according to the minimal level of platelets in pregnancy ( platelets count was lower than 100 ×109/L at least twice) : groupⅠ,(50-100) ×109/L (n=101) ; group Ⅱ,(30-50) × 109/L (n = 85); group Ⅲ,(10-30) × 109/L (n = 87); group Ⅳ,< 10 × 109/L (n = 32).Demographic data such as pregnancy complications,treatment,neonates and follow-up results of the patients in each group were compared with ANOVA,Spearman rank correlation analysis,Chirsquare test and Chi-square trend test in SPSS 17.0.Results Medical complications in pregnancy of these patients included hypertensive disorder complicating (n = 35,11.48%) and abnormal glucose metabolism (n=23,7.54%),no difference was found in the incidence of these diseases among the four groups.There were 68 patients complicated with anemia (22.30%),40 preterm delivery (13.11%),60 postpartum hemorrhage (19.67%); there were significant differences in the incidence among the four groups (P＜0.05),the incidence increased with the aggravation of thrombocytopenia (P＜0.05).There were 2 cases of puerperal infection (0.66%),no maternal deaths.Fifty-one patients (16.72%) accepted treatment of corticosteroids or Gamma globulin during pregnancy.There were 116 cases (38.03%) of vaginal delivery and 189 cases (61.97%) of cesarean section.The postpartum bleeding amount within 24 hours increased with the aggravation of thrombocytopenia.Two hundred and eleven (69.18%) patients were followed up and platelet count regained normal,among which 152 cases recovered within six months after delivery.The recovery rates were 90.59% (77/85),82.36% (42/51),46.16% (24/52) and 39.13% (9/23) from group Ⅰ to group Ⅳ,as declined with the aggravation of thrombocytopenia in pregnancy ( x2trend = 42.616,Ptrend =0.000).Among the 306 perinatal fetuses,neonatal outcomes included 301 live births,5 fetal deaths,4 early neonatal deaths,4 low birth-weight infants after term birth,1 intracranial hemorrhage and 18 (5.98%) neonatal thrombocytopenia cases.Incidence of neonatal thrombocytopenia increased with the aggravation of maternal thrombocytopenia.Sixteen cases of neonatal thrombocytopenia recovered at 3-8 weeks after birth,but two cases did not recover within three years during followed up.Conclusions The perinatal outcomes are different in pregnancies complicated with varying degrees of thrombocytopenia.As thrombocytopenia in pregnancy become worse,the risk of anemia,premature delivery,postpartum hemorrhage and neonatal thrombocytopenia increases.While,perinatal outcomes may be better under close perinatal care.

妊娠期肝内胆汁淤积症发生死胎的临床因素分析

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.

细胞因子信号传导负调控因子3在妊娠期肝内胆汁淤积症孕妇胎盘组织中的表达及其意义

Objective To detect the expression and significance of suppressor of cytokine signaling 3(SOCS3) in the placentas of pregnant women with intrahepatic cholestasis of pregnancy (ICP). Methods Totally, 44 ICP gravidas, including 21 severe ICP and 23 mild ICP who delvered through cesarean section at the Second Xiangya Hospital of Central South University from April 2008 to January 2009, were selected as the ICP group, and another 25 healthy pregnant women were chosen as control. Placentas of the above gravidas were collected and the expression and localization of SOCS3 were determined by immunohistochemical peroxidase streptomyces-avidin link (SP) method (indicated by the percentage ofpositive cells and average gray scale) and the levels of interleukin-10 (IL-10) and interferon-γ (IFN-γ)from placenta homogenation were measured by enzyme linked immunoadsorbent assay (ELISA). Results(1) SOCS3 were expressed in placentas of both groups mainly in the intracytoplasma of trophocyte.However, weakly positive, positive, and strongly positive expressions were found in the severe ICP, mild ICP and the control group, respectively. Almost no expression was detected in membrane and nucleus of the trophoblasts. (2) The percentage of SOCS3 positive cells in the severe ICP group was significantly lower than in the control and the mild ICP group, respectively [ (0.15±0.08)% vs (0.69±0.12)% and (0.42±0.09) % , P < 0.01 ]. The average gay SOCS3 in placental tissue in the severe ICP group was significantly higher than that in control and mild ICP group, respectively (204 ±7 vs 81 ±7 and 147 ± 7, P <0.01 ).(3) Significant lower level of IL-10 in placenta homogenation was found in the severe ICP group than in the control and mild ICP group [ ( 1.16 ± 0.68) μg/L, vs ( 1.39 ± 0.08) μg/L and ( 1.22 ± 0.75 ) μg/L,P < 0.01 ]. (4) The opposite results were found in the level of IFN-γin trophoblasts and the ratio of IFN-γ/IL-10 [ severe ICP group: ( 16.8 ± 0.7 ) μg/L and 16.02 ± 2.79; control group: ( 10.5 ± 0.3 ) μg/L and8.56 ±0.14; mild ICP group: ( 13.4 ±0.5) μg/L and 8.56 ±0.14, P <0.01]. (5) Negative correlation was shown between the percentage of SOCS3 positive cells in trophoblasts and the ratio of IFN-γ/IL-10 ( r =-0.685 and -0.702, P < 0.01 ), and the average gay SOCS3 was positively correlated with the ratio of IFN-γ/IL-10 (r=0.621 and 0.891, P<0.01) in both mild and severe ICP group. Conclousions SOCS3 may participate in the pathogenesis of ICP and its expression may affected by the severity of ICP, and SOCS3may also play a role in the immunological regulation in ICP patients.

妊娠合并甲状腺功能减退症或亚临床甲状腺功能减退症77例临床分析

Objective To investigate the maternal and fetal outcomes of pregnant women with hypothyroidism or subclinical hypothyroidism. Methods From Jan. 2005 to Mar. 2008, clinical records of 77 women with hypothyroidism (n=57) or subclinical hypothyroidism (n = 20) during pregnancy who delivered at Peking Union Medical College Hospital were reviewed. The basic information, maternal complications and neonatal outcomes of the patients were compared with 79 healthy women who delivered during the same period. Results The prevalence of maternal hypothyroidism during the study period was 0.74% ,and that of maternal subclinical hypothyroidism was 0.26%. The mean neonatal birth weight of women with hypothyroidism was lower than that of the control [(3191.8±659.47 g) vs (3301.9±423. 1 g), P<0.05], the incidence of abnormal glucose metabolism was higher (24.6% vs 11.4% ,P<0.05), and small for gestational age infants were more common than in the control group (12. 3% vs 2. 5%, P<0. 05). The maternal and fetal outcomes of women with subclinical hypothyroidism during pregnancy showed no difference compared with the control. Conclusions Early screening for the high risk women and appropriate management are important to improve the neonatal and fetal outcomes of women with hypothyroidism and subclinical hypothyroidism during pregnancy.

Conclusions Early screening for the high risk women and appropriate management are important to improve the neonatal and fetal outcomes of women with hypothyroidism and subclinical hypothyroidism during pregnancy.
