RESUMO
Objective:To investigate the effects of peripartum administration of low-dose corticosteroids or intravenous immunoglobulin (IVIG) on delivery outcomes in pregnant patients with primary immune thrombocytopenia (ITP).Methods:This prospective cohort study involved pregnant women (≥34 gestational weeks) who were diagnosed with ITP in Peking University People's Hospital from January 2017 to December 2021. Their platelet counts were between 20×10 9/L to 50×10 9/L without bleeding and none of them had been treated with any medications. All patients were divided into medication group (prednisone or IVIG) and platelet transfusion group based on their preference. Differences in vaginal delivery rate, postpartum hemorrhage rate and platelet transfusion volume between the two groups were compared using t-test, Wilcoxon rank sum test and Chi-square test. Binary logistic regression was used to investigate the factors influencing the rates of vaginal delivery and postpartum hemorrhage. Multiple linear regression was used to analyze the factors influencing the platelet transfusion volume. Results:A total of 96 patients with ITP were recruited with 70 in the medication group and 26 in the platelet transfusion group. The vaginal delivery rate in the medication group was higher than that in the platelet transfusion group [60.0% (42/70) vs 30.8% (8/26), χ 2=6.49, P=0.013]. After adjusted by the proportion of multiparae and the gestational age at delivery, binary logistic regression showed that the increased vaginal delivery rate in patients undergoing the peripartum treatment ( OR=4.937, 95% CI: 1.511-16.136, P=0.008). The incidence of postpartum hemorrhage in the two groups was 22.9% (16/70) and 26.9% (7/26), respectively, but no significant difference was shown ( χ 2=0.17, P=0.789). The median platelet transfusion volume was lower in the medication group than in the platelet transfusion group [1 U(0-4 U) vs 1 U(1-3 U), Z=－2.18, P=0.029]. After adjustment of related factors including the platelet count at enrollment, obstetrical complications and anemia, multiple linear regression showed that the platelet transfusion volume was also lower in the medication group (95% CI:0.053-0.911, P=0.028). Ninety-six newborns were delivered without intracranial hemorrhage. The overall incidence of neonatal thrombocytopenia was 26.0% (25/96). There was no significant difference in birth weight, and incidence of neonatal asphyxia or thrombocytopenia between the two groups. Conclusion:Peripartum therapy in ITP patients may increase vaginal delivery rate and reduce platelet transfusion volume without causing more postpartum hemorrhage.
RESUMO
Objective:To understand the progress, maternal morbidity, and maternal and infant outcomes in pregnant women with non-severe primary immune thrombocytopenia (ITP) during two consecutive pregnancies.Methods:This study retrospectively analyzed the clinical data of 40 patients with non-severe ITP who had two pregnancies and were treated at Peking University People's Hospital between June 2010 and June 2020. Platelet counts at different stages of pregnancy, treatments, maternal complications and neonatal outcomes were compared with Chi-square test, Fisher's exact test, paired sample t-test, non-parametric Wilcoxon signed rank test, independent sample t-test or non-parametric Mann-Whitney U test. Results:Among the 40 patients, 18 were diagnosed before and 22 were first diagnosed during the first gestation. Platelet counts and treatments in the 18 patients prior to their first conception were not significantly different from those in the 40 patients before their second pregnancy (all P>0.05). No significant difference in the average platelet count and thrombocytopenia severity at each stage of pregnancy, and maternal bleeding score or drug treatment was observed between the two pregnancies (all P>0.05), neither in the incidence of gestational hypertension, gestational diabetes, premature rupture of membranes, premature delivery, or anemia (all P>0.05). The incidences of postpartum hemorrhage and severe postpartum hemorrhage in the second pregnancy were 30.0%(12/40) and 22.5%(9/40), respectively, which were both higher than those in the first gestation [(7.5%(3/40) and 5.0%(2/40); χ2=6.64, 5.17; P=0.010, 0.023]. The amount of postpartum hemorrhage was higher in the second pregnancy than in the first [500 ml(213-795 ml) vs 300 ml(163-400 ml), Z=－2.34, P=0.019]. There was no significant difference in birth weight, the incidence of passive ITP or intracranial hemorrhage, or mortality between the neonates of the first and second pregnancy group (all P>0.05). The lowest platelet count in neonates within one week after birth in the second pregnancy group was (202.2±106.7)×10 9/L, which was lower than that of the first [(222.5±91.8)×10 9/L, Z=－2.04, P=0.041]. Conclusions:Non-severe ITP is not worse in the second pregnancy than in the first. In women with non-severe ITP, the incidence of maternal complications is not increased in the second pregnancy, but the risk of postpartum hemorrhage and the incidence of neonatal passive immune thrombocytopenia are raised.
RESUMO
Objective:To explore the progression of paroxysmal nocturnal hemoglobinuria (PNH) during pregnancy and treatment for improving maternal and infant outcomes.Methods:Nine pregnant women with PNH were admitted to the Obstetrics Department of Peking University People's Hospital from September 2010 to September 2020. The clinical data of these patients were retrospectively collected and analyzed. Relevant literature was reviewed to summarize the progression, treatment, complications, perinatal outcomes, and follow-up of PNH during pregnancy. Descriptive methods were used for statistical analysis.Results:Among the nine patients, six were classic PNH, and three combined with bone marrow failure disease. Eight cases received blood transfusion/low-dose corticosteroids or combination therapy during pregnancy, and four of them were also received anticoagulants. In seven out of the eight patients diagnosed prenatally, the disease worsened during pregnancy. Complications were noted in eight patients during pregnancy, including fetal growth restriction in seven cases, hypertension and premature delivery in four cases each, thrombosis and intrauterine fetal death in one case each. No maternal deaths were reported, with a live birth rate of 8/9 between 33-38 gestational weeks, with the median at 37 weeks. The median time of postpartum follow-up was 50 months (4-92 months), during which the patients' conditions were all stable, and no abnormalities were found in the growth and development of the babies.Conclusions:Pregnant women with PNH tend to worsen with an increased incidence of perinatal complications and adverse outcomes. Multidisciplinary management is recommended for this population may help improve maternal and infant outcomes.
RESUMO
Objective@#To analyze the maternal and fetal outcomes of pregnancies complicated by aplastic anemia (AA) and to investigate the underlying risk factors.@*Methods@#In this retrospective case control study, we retrieved medical records of 85 singleton gravidas with AA (AA group) who were admitted to Peking University People's Hospital from January 2003 to January 2016, and another 340 singleton gravidas (case∶control=1∶4) without blood system or immune system diseases who gave birth at the same period were selected as the control group. Differences in general condition and the incidence of maternal and neonatal complications were compared between the two groups. AA group were further divided into adverse outcome subgroup (n=33) and non-adverse outcome subgroup (n=52), and relevant factors were also analyzed. Statistical analysis was performed using t-test, Chi-square test and logistic regression.@*Results@#No maternal deaths occurred in all 85 cases of AA group, 81 of them gave live birth [one neonate died and the others survived with a mean gestational age of 36+5 weeks (30+2-40+5 weeks)], and 45 developed maternal or fetal adverse outcomes. Compared with the control group, AA group had higher incidences of hypertensive disorders of pregnancy [20.0% (17/85) vs 6.2% (21/340)], acute heart failure [7.1% (6/85) vs 0.0% (0/340)], postpartum hemorrhage [5.9% (5/85) vs 0.9% (3/340)], puerperal infection [2.4% (2/85) vs 0.0% (0/340)], preterm birth [22.3% (19/85) vs 5.6% (19/340)], small for gestational age [11.7% (10/85) vs 0.9% (3/340)], fetal growth restriction [8.2% (7/85) vs 1.2% (4/340)], intrauterine fetal death [4.7% (4/85) vs 0.0% (0/340)] and neonatal death [1.2% (1/85) vs 0.0% (0/340)] (all P<0.05). After adjusting for age, pregnancy history and the time of diagnosis, we found that low median (OR=0.88, 95%CI: 0.83-0.95), mean (OR=0.85, 95%CI: 0.79-0.93) and minimal (OR=0.87, 95%CI: 0.82-0.93) values of hemoglobin concentration during pregnancy, and low median (OR=0.96, 95%CI: 0.92-1.00), mean (OR=0.96, 95%CI: 0.92-1.00) and minimal (OR=0.95, 95%CI: 0.90-0.99) values of platelet counts during pregnancy were risk factors for adverse maternal and fetal outcomes of gravidas with AA (all P<0.05).@*Conclusions@#Maternal and fetal complications are more common in pregnant women with AA and maintain hemoglobin and platelet counts at a certain level may improve the outcomes.

RESUMO
Objective To explore the pregnancy outcomes of women with pancytopenia and the risk factors for the adverse perinatal outcomes.Methods A total of 106 pregnant women with pancytopenia were admitted to Peking University People's Hospital from Jan.2005 to Sep.2014.The clinical data and the pregnancy outcomes were reviewed retrospectively to investigate the risk factors for the adverse perinatal outcomes.Results (1)Eighty-four patients were found pancytopenia before pregnancy while 22 were found for the first time during pregnancy.Sixty-four patients were diagnosed as aplastic anemia;30 as myelodysplastic syndrome;2 as paroxysmal nocturnal hemoglobinuria;4 as hypersplenism,and 1 as anti-phospholipid syndrome.Diagnoses of the remaining 5 patients were uncertain.(2)Sixty-nine patients received at least one time blood transfusion before delivery.(3) As for the complications,nine women developed gestational diabetes;twenty-two suffered severe preeclampsia (SPE);two were diagnosed as anemic heart disease and three experienced respiratory tract infection.The postpartum blood loss ranged from 50 ml to 3 800 ml,with the median of 400 ml.And six women had the blood loss more than 1 000 ml.The gestational age at delivery ranged from 24 weeks to 40 weeks,with the median of 37.0 weeks.(4)Thirty-one patients suffered adverse perinatal outcomes,including 3 cases of intrauterine death,4 therapeutic labor induction before 28 gestational weeks,6 premature delivery before 34 weeks.There were 2 neonates complicated with intracranial hemorrhage,2 with neonatal respiratory distress syndrome,3 with hypoxic-ischemic encephalopathy,2 with severe asphyxia and death,and 14 with small for gestational age.Among the patients with adverse perinatal outcomes,26 women received blood transfusion during pregnancy and 17 developed SPE.The maximum and the minimum value of their white cell count (WBC),hemoglobin concentration (Hb) and blood platelet count (BPC) were (4.9± 1.4)× 109/L,(2.9±0.8)× 109/L,(88.6± 14.9) g/L,(57.9 ± 14.5) g/L,(47.7±27.4)× 109/L and (11.9 ± 12.3)× 109/L,respectively.For those patients without adverse perinatal outcomes,43 received blood transfusion during pregnancy and 5 developed SPE.The maximum and the minimum value of their WBC,Hb and BPC were (5.2±1.5)×109/L,(3.2±0.9)×109/L,(101.4±16.2) g/L,(71.9 ± 14.5) g/L,(52.3 ± 24.0)× 109/L and (19.0 ± 12.1)× 109/L,respectively.The multivariate regression analyses indicated that SPE,Hb less than 70 g/L and BPC less than 20× 109/L were the independent risk factors for the poor perinatal outcomes in pregnant women with pancytopenia (P＜0.05).Conclusions The incidence of adverse perinatal complications increased dramatically in pregnant women with pancytopenia.Concurrent SPE,minimum Hb less than 70 g/L and minimum BPC less than 20 × 109/L may be the independent risk factors for the adverse perinatal outcomes.
RESUMO
Objectives To summarize the maternal and fetal outcomes of patients with essential thrombocythemia (ET), and tentatively propose possible solutions for different clinical scenarios.Methods We retrospectively studied the clinical data, treatment, outcomes and follow-up status in 18 consecutive cases of young women with ET visited Peking University People's Hospital, among whom 22 pregnancies occurred from March 2005 to January 2015.Rank-sum test, Chi-square test or Fisher exact test were applied for statistics.Results (1) Out of the total 22 pregnancies, 17 (77％) were successful (term live births) and five (23％) ended in miscarriages, among which four were spontaneous abortion in first trimester.(2) Six pregnancies did not received any therapy, while 16 received various treatments before and/or during pregnancy, including oral Aspirin(single/joint), Hydroxyurea, Interferon-α (IFN-α) and platelet apheresis.(3) Treatments before/during pregnancy improved the live birth rate significantly (15/16 vs 2/6, P=0.009).Platelet (PLT) count of the newborns were all normal till the time at follow-up.(4) The median PLT count in those patients before Aspirin therapy was 761 × 109/L[(448-1 213) × 109/L, and 639× 109/L[(283-1 908) × 109/L] thereafter, which showed no significant difference (Z=-0.405, P=0.686).(5) The PLT counts in those patients before combination therapy of Aspirin and IFN-α was 989 × 109/L[(435-1 504) × 109/L], and 498 × 109/L[(186-559) × 109/L] thereafter, which decreased significantly (Z=-2.366, P=0.018).Conclusions (1) First-trimester spontaneous abortion is the most common complication of ET in pregnancy.(2) A specific treatment strategy may improve the pregnant outcomes without long-term harmful effect up to now.(3) IFN-α and/or Aspirin might be the first-line therapy in women with ET during pregnancy.
RESUMO
Objective To investigate the effect of collaborative ward rounds of doctors and nurses.Methods The department of cardiovascular diseases was involved in the trial. The conventional nursing ward rounds from January to June 2012 were set as control group(before collaborative ward rounds)and the collaborative rounds were as the experiment group from July to December 2012(after collaborative ward rounds). The degree of satisfaction of doctors and patients with nurses in the department was investigated before and after the implementation.Result The level of satisfaction of doctors and patients with nurses after the implementation was significantly higher than that before the implementation(P<0.05).Conclusion Collaborative clinical rounds can improve the quality of holistic nursing and raise the level of satisfaction of doctors and patients with nurses.
RESUMO
Objective To investigate the perinatal outcomes and management of pregnancy with leukemia.Methods From June 1,1980 to July 31,2011,23 pregnant women with leukemia,were admitted to the Department of Obstetrics of Peking University People's Hospital.Clinical data of these women were collected and analyzed retrospectively.Among the 23 cases,nine were diagnosed before pregnancy including four with acute myeloid leukemia (AML) and five with chronic myeloid leukemia (CML),and 14 diagnosed during pregnancy including eight with acute leukemia (AL) [seven with AML and one with acute lymphocytic leukemia (ALL)] and six with CML.The prognosis of the mothers and infants were followed up.Results (1)Managements during pregnancy:For the four cases with AML,two were completely recovered and the other two had completed chemotherapy five years before pregnancy,and no relapse was reported during pregnancy.The other five cases with CML were stable during pregnancy although the results of blood routine tests were abnormal.Among them,one case was treated with hydroxyurea and one with imatinib during pregnancy,while the other three women received no treatment.For those 14 cases diagnosed during pregnancy,all were recorded with abnormal white blood counts,and nine complicated with anemia and abnormal platelet count and four with either anemia or abnormal platelet count.Among the eight cases with AL,six received chemotherapy during pregnancy and two did not due to intrauterine fetal death and 40 weeks of gestation on admission,respectively.For the six CML women,two received hydroxyurea,one took imatinib,one took leukapheresis and one accepted plateletpheresis during pregnancy,but one woman received no treatment due to regular contractions on admission.(2) Perinatal outcomes:The average gestational weeks on delivery was (38.3±2.3) weeks,and the average birth weight of newborns was (2 755 ±486) g.There were two cases of disseminated intravascular coagulation,five pre-eclampsia and one placental abruption during pregnancy.Five women were complicated with postpartum hemorrhage [average bleeding volume was (1 200± 751) ml] and two cases of puerperal infection.One pregnant woman died.Among the 23 perinatal infants,there were four premature infants,four low birth weight infants,two still births,one with congenital malformations,and two infants had abnormal blood routine tests.Eight babies were delivered by caesarean section,12 through vagina and two required forceps assistants.(3) Follow-ups:Except for one woman died during pregnancy,four of the other 22 cases were lost.Among the rest 18 cases with the follow-up from three months to 13 years,11 women survived and seven died due to leukemia.All newborns were healthy.Conclusions Pregnancy with leukemia is an extremely high-risk obstetric condition,but for patients with bearing requirement,better perinatal outcome might be achieved under proper management.
RESUMO
Objective To investigate maternal risk factors for fetal congenital heart diseases (CHD). Methods A case-control study was conducted on 16 645 pregnant women who underwent cardiovascular malformation screening for fetal cardiovascular system,whose pregnancy outcomes were recorded,and whose newborns were scanned by an echocardiography in Peking University People's Hospital,Haidian,Changping,Mentougou and Daxing Maternal and Child Health Hospital from Nov.2006 to Oct.2009.One hundred and twelve pregnant women whose babies were found to be CHD (40 severe CHD and 72 simple CHD) before or after delivery were taken as study group.Women in control group (n =304) were randomly selected from those pregnant women who had infants without CHD.Logistic regression analysis and x2 test were used to analyze the maternal risk factors for fetal CHD. Results (1) The average age of women whose infants had severe CHD was 28.3 years (21-40 years),and it was 29.9 years (22-39 years) for women whose infants had simple CHD.There were no significant differences between the control group (29.5 years,20-44 years) and the above two groups (t=1.511 and -0.826,P=0.138 and 0.410 respectively).(2) Single factor analysis:during first trimester,the rate of upper respiratory infection (18/39,46.2 ％) and exposure to certain chemicals (13/40,32.5％) of severe CHD group were higher than those of control group [(14.9％ (45/303) and 2.0％ (6/304)] (x2 =22.399 and 62.678,OR=4.895 and 23.753,95％CI:2.419-9.905 and 8.358-67.506,P =0.000 respectively).Compared with control group (0.0％,0/304),the rate of pregnant women with CHD family history in simple CHD group was significantly higher (4.2％,3/72)(Fisher exact test,P=0.007).(3) Logistic regression analysis:maternal upper respiratory infections (OR =5.120,95％CI:2.340-11.206,P =0.000) and exposure to certain chemicals (f)R=23.030,95％CI:7.506-70.665,P=0.000) during first trimester were risk factors for fetal severe CHD. Conclusions Upper respiratory infection and exposure to certain chemicals during first trimester might play important roles in the occurrence of fetal severe CHD.Maternal family history of CHD might associate with fetal simple CHD.
RESUMO
Objective To investigate the pregnancy opportunity and outcome of patients with sysmetic lupus erythematosus (SLE).Methods We carried out a retrospective analysis of the clinical information of patients who suffered from SLE complicated with pregnancy and were hospitalized to People's Hospital of Peking University from December of 1992 to February of 2012.Chi-square test were used for statistical analysis.Results Forty-nine cases of patients with SLE complicated with pregnancy had 52 pregnancies in total.In 27 cases of planned pregnancies,24 cases(89％ )resulted in live births and 5 cases( 18％ ) had flares during pregnancy.Of the 24 live births,3 cases( 12％)were premature deliveries and 4 cases(17％) had low birth weight infants.In 25 cases of unplanned pregnancies,12 cases (48％) resulted in live births and 20 cases (80％) had flares during pregnancy.Of the 12 live births,6 cases(50％ ) were premature deliveries and 6 cases (50％) were low birth weight infants.The patients in the planned pregnancy group tended to have flares during pregnancy more frequently than those in the unplanned group (P＜0.01),the former were more likely to have live births than the latter (P＜0.01) and were less likely to have premature delivery (P＜0.05).Conclusion Patients with SLE should have planned pregnancy and need collaborative supervision of both rheumatology and immunology department and obstetric department to improve live birth rate,decrease premature delivery and the activity of SLE during pregnancy.
RESUMO
Objective To investigate the risk factors for preeclampsia (PE) in pregnancies complicated with chronic aplastic anemia ( CAA ) by analyzing the obstetric management and pregnancy outcome.Methods Retrospectively review the clinical data including the obstetric management,the laboratory findings and the pregnancy outcome of 41 pregnant women complicated with CAA,all of whom were hospitalized in Peking University People's Hospital from May 2002 to February 2011.Multiple logistic regression was used to explore the risk factors associated with PE.Results ( 1 ) Twenty-eight patients were diagnosed before conception while 13 were diagnosed during gestation.Eleven patients including all the 7 who were categorized as severe CAA presented with mild bleeding in the third trimester.( 2 ) The medians of white blood cell counts,hemoglobin concentrations and platelet counts were 5.0 × 109/L,66.0 g/L and 12.0 × 109/L respectively.(3) The obstetric management consisted of strict assessment, intensive surveillance and follow-up,appropriate supportive measures,timely recognition of complications,and delivery when necessary.Twenty-one patients received supportive transfusions.Ten patients developed PE,all of whom were diagnosed as severe PE( SPE).Twelve patients suffered postpartum hemorrhage,and 3 of them had blood loss more than 1000 mL All were conservatively treated in success.(4) The median gestational age of delivery was 37 weeks.Sixteen cases delivered before 37 weeks and 5 delivered before 34 weeks.Two patients developed SPE at 29 weeks and 30 weeks respectively,and both of the neonates died for severe asphyxia.The birth weight of the live neonates ranged from 1500 to 3660 g.(5) The postpartum follow-up period ranged from 6 months to 7 years.Thirty-three patients got improvement without dependence on transfusions.Four achieved no remission and still needed intermittent transfusions.Four were lost in followup.(6) Significant differences were found in the bleeding tendency,the platelet counts and the delivery weeks when comparing the patients developing PE and those without PE.No differences were found with regard to the age,the gestational age of first visit,the percentage of patients diagnosed before conception,the percentage of severe CAA,the choice of treatment,the white blood cell counts and the hemoglobin level.The Multiple logistic regression showed that the platelet count less than 10 × 109/L was an independent risk factor for CAA patients developing PE (P =0.006).Conclusions Most pregnancies complicated with CAA could achieve good maternal and fetal outcome, when intensive prenatal care and supportive management are provided SPE is the most common complication.The platelet count less than 10 × 109/L is perhaps an independent risk factor for CAA patients developing PE.
RESUMO
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.
RESUMO
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.
RESUMO
Objective To investigate the perinatal outcomes of pregnancy with chronic myeloid leukemia (CML) and how to manage it during pregnancy. Methods To retrospectively analyse the clinical datas about the perinatal outcome and the obstetric management of the 16 cases of pregnancy with CML during the last 30 years in a single center. Results ( 1 ) Management ang perinatal outcomes: among the 16 pregnancies nine ended with therapeutic abortion during the first or second trimester and no CML complications were observed. The average gestation week was 7 weeks(5 - 13 weeks)when they came to our hospital. Seven pregnancies gave birth, among which CML was diagnosed during pregnancy in four patients and pregnancy was confirmed during CML in three patients. The average gestation week was 36 weeks (27 -40 weeks +2)when they came to our hospital. Among the seven women three were treated with hydroxyurea (one became pregnant while she was on hydroxyurea and she elected to continue her pregnancy and continued to use hydroxyurea), one with leukapheresis twice after her 40 weeks of gestation, one with plateletpheresis and three hadn't any treatment. In the seven pregnacies three developed severe preeclampsias, including the two had hydroxyurea during the gestation. The average delivery gestational week was 38 weeks (33 weeks +4 -41 weeks), two were premature birth. Two caesarean sections, three vaginal deliveries and two forceps deliveries. There were two postpartum hemorrhage, during the 24 hours the amount of bleeding was 1500 - 1800 ml and secondary disseminated intravascular coagulation happened. Seven patients gave birth to seven infants whose average birth weight was 2469 g( 1820 - 2810 g), of whom two were premature infants, two low birth weight infants, one had congenital malformation and two had abnormal blood routine examinations. (2) Management after delivery and prognosis: during the nine patients who ended pregnancy with therapeutic abortion during the first or second trimester four withdraw, one died whose course of disease was 3 years and the other four were alive during 5 months to 72 months, among which one had stem cell transplantation, two are taking imatinib mesylate and one takes hydroxyurea. Among the seven patients who deliveried two withdraw, two died and three are alive. Among the seven infants two withdraw,the other five have normal development following 4 months to 9 years. Conclusions CML patient may have successful pregnancy and delivery, and it is not the absolute indication for terminating pregnancy. On the other hand, CML and the treatment during pregnancy can have side effect on the mother and the fetus, so the patients should be monitored and treated in tertiary hospitals.
RESUMO
Objective To investigate the clinical characteristics, the antenatal management, the outcome and prognosis of chronic myeloproliferative disorders (CMPD) complicating pregnancy. Methods Retrospectively analyze the clinical data of eleven patients with CMPD complicating pregnancy hospitalized in Peking University People' s Hospital from 2000 to 2009, including five patients with essential thrombocythemia, one with primary myelofibrosis and five with chronic myeloid leukemia. Results (1)Five pregnancies had periodic antenatal care and laboratory monitorings like full blood count. Reasonable anti-coagulation therapy was given to prevent the complications. One patient with PMF diagnosed before conception had her first pregnancy ended with mild pre-eclampsia and intrauterine death at the gestational age of 32 weeks. During the first trimester of her second pregnancy two years later, the test for anti-β2 glycoprotein antibody was positive. She received low-dose aspirin and low-molecular-weight heparin as anticoagulants. An uneventful course was obtained and she delivered a healthy term infant. (2) Five pregnancies had occasional antenatal examination, including two patients with ET and three patients with CML One patient with ET developed severe pre-eclampsia at the gestational age of 25 weeks. Umbilical artery Doppler showed reversed end-diastolic velocity. The management with anti-convulsants, antihypertensives and anti-coagulants showed no effect. An emergency cesarean section had to be performed because of the aggressive hypertension and placental abruption, with still birth as a result. Two pregnancies never had an antenatal care. Both of them were admitted on labor and the diagnoses of CML were made. (3)Four pregnancies developed oligohydramnios and three developed preelampsia(two severe pre-eclampsia and one mild pre-eclampsia). There was no other hemorrhage and thrombosis event. (4) Eight pregnancies reached full-term with four cesarean sections and four vaginal births. Two preterm cesarean sections were performed because of a progressive oligohydramnios. The ten live neonates weighed 1820 - 3600 g. All were appropriate for gestational age, except one fetal growth retardation (FGR) developed in one patient with severe pre-eclampsia. (5) As for the CMPD, the eleven patients were all in stable conditions. Three patients with CML received hydroxyurea in the third trimester, four with ET and one with CML had plateletpheresis before delivery with favorable effect. All patients were uneventful postpartum, except one with CML who died in 5 months after childbirth. Conclusions The pregnancy outcomes for patients with CMPD are mostly good. However, antenatal care should pay more attention to the complications such as thromboembolic accidents, pre-eclampsia, still birth and fetal growth retardation. Management including reasonable anticoagulation therapy should be considered, which may help improve the prognosis.
RESUMO
Objective To investigate the effect of general anesthesia on pregnancy women with thrombocytopenia and neonate during cesarean section(CS). Methods Sixty-five singleton pregnant women with low platelet count (<50×10~9/L) and gestation >35 weeks were allocated into general anesthesia group (35 cases) and local anesthesia group (30 cases) randomly. The time from skin incision to fetal delivery, the oxyhemoglobin saturation(SO_2) before and after anesthesia, the blood loss during operation, Apgar scores at 1 min, birth weight, umbilical cord blood gas analysis were recorded. Results The mean time from anesthesia induction to fetal delivery was (9.7±3.5) minutes in general anesthesia group. The time from skin incision to fetal delivery in general anesthesia group [(7.7±2.5) minutes] was shorter than that in local anesthesia group [(12.5±3.0) minutes, P<0.01], while the operation time had no significant differences. There were no significant difference for the value of SO_2 before and after general anesthesia or local anesthesia(P>0.05). There was no significant difference for the blood loss [(471±245)ml vs. (452±213 )ml, P>0.05], Apgar scores at 1 minute, birth weight and umbilical cord blood gas analysis between the two groups (P>0.05). There had two infants with blue asphyxia in local anesthesia group while no infant with asphyxia in general anesthesia group. Conclusion General anesthesia is safe to pregnant women with thrombocytopenia during CS.
RESUMO
Objective To evaluate the diagnosis and the optimal management of idiopathic thrombocytopenic purpura(ITP) with pregnancy and the related high risk factors with neonatal passive immune thrombocytopenia(PIT) occurring in infants born to mothers with ITP. Methods Medical records of 40 pregnant women with ITP and their neonatal outcomes were reviewed retrospectively from 1992.2 to 2001.8 in our hospital. Results The incidence of pregnancy with ITP was 3.4‰. The maternal complications included pregnancy-induced hypertension syndrome (17.5%), postpartum hemorrhage (15%), preterm labor (12.5%), gestational diabetes(7.5%) and FGR (7.5% ). One mother died at 36 weeks of gestational age. There were 13 cases delivered by vagina and 27 cases delivered by cesarean section. Nine neonates(28.1%)had neonatal PIT, Among them three neonates (9.3%) had severe PIT, One neonate(2.5%) had an intracranial hemorrhage(ICH) and two perinatal death (5%)occured in 40 neonates. No significant correlation was found between neonatal platelet counts and maternal platelet counts, maternal PAIgG values and maternal treatments respectively. Conclusion The prognosis of mothers and neonates in pregnancy with ITP are better. The incidence of severe fetal or neonatal PIT is low and not related to maternal platelet counts, maternal treatments and PAIgG values.
