The value of combined detection of sFIt-1, PLGF and Survivin in the diagnosis of early-onset preeclampsia / 中国医师进修杂志

s] Objective To analyze the diagnostic value of combined detection of sFIt-1, PLGF and Survivin in early onset preeclampsia. Methods From January 2017 to January 2018, 100 patients with early-onset PE were selected as observation group and 100 healthy pregnant women as control group in Tangshan Maternal and Child health Hospital Gynecology and Obstetrics. The expression levels of sFIt-1, PLGF and Survivin in serum were detected by enzyme-linked immunosorbent assay (ELISA), and the diagnostic value of each index was analyzed separately and jointly. Results The levels of sFIt-1 in the observation group were significantly higher than those in the control group: (36.58 ± 18.34) μg/L vs. (28.43 ± 3.28) μg/L (P<0.05), and the levels of PLGF and Survivin in the observation group were significantly lower than those in the control group: (213.18 ± 48.23) ng/L vs. (398.17 ± 41.19) ng/L, (0.72 ± 0.29) μg/L vs. (1.43 ± 0.32) μg/L (P<0.05); 103 cases of positive sFIt-1, 108 cases of positive PLGF, 107 cases of positive Survivin, 121 cases of positive parallel combined diagnosis and 121 cases of positive series combined diagnosis were found. The sensitivity and negative predictive value of parallel combined diagnosis were significantly higher than those of individualized diagnosis (P<0.05), and the specificity and positive predictive value of series combined diagnosis were significantly higher than those of individualized diagnosis (P < 0.05). Conclusions The combined detection of sFIt-1, PLGF and Survivin in serum can effectively improve the diagnostic accuracy of early-onset preeclampsia and has high clinical value.

Comparison of the diagnostic accuracy of early screening for Preeclampsia by NICE guidelines, ACOG guidelines and comprehensive first trimester screening using maternal characteristics, ultrasonographic findings and maternal serum biochemical markers in the prediction of the development of Preeclampsia in a tertiary hospital / Philippine Journal of Obstetrics and Gynecology

Introduction@#Preeclampsia remains to be a major cause of both fetal and maternal morbidity and mortality, particularly in severe forms leading to preterm birth. There is a lack of consensus, however, on the preferred screening test for early diagnosis with the aim of reducing the prevalence and morbidity of the disease. @*Objective@#To compare the performance of the comprehensive first trimester screening using maternal characteristics, ultrasonographic findings and serum biochemical markers, with the NICE and ACOG guidelines in predicting the development of preeclampsia. The study also aims to determine the compliance rate of clinicians in giving aspirin prophylaxis using the different screening tests. Methodology: This is a retrospective, analytical, cross sectional study of all pregnant patients between 11 to 13 6/7 weeks referred for comprehensive first trimester screening for preeclampsia from January 2014 to January 2018. Maternal factors were assessed to determine the risk of preeclampsia using NICE guidelines, ACOG guidelines and comprehensive first trimester screening. The compliance on aspirin administration for high-risk patients was also determined. The outcome measure was diagnosis of preeclampsia and the detection rate (DR) of the three screening tests were compared. @*Results@#A total of 202 women were included in the analysis where 24 (11.9%), 11 (5.4%) and 13 (6.4%) developed preeclampsia, early-onset preeclampsia (EO-PE) and late-onset preeclampsia (LO-PE) respectively. The NICE and ACOG guidelines were able to detect preeclampsia with an accuracy of 76.73% (Sn 75%, Sp 77% PPV 30.5%) and 43.07% (Sn 83.3%, Sp 37.6% PPV 15.3%) respectively. The comprehensive first trimester screening was able to detect preeclampsia with an accuracy of 89.60% (Sn 83.3%, Sp 90.5% PPV 54.1%). EO-PE and LO-PE were detected with an accuracy of up to 97.2% using the comprehensive screening (Sn 90.9%, Sp 97.9% PPV 71.4%), compared with the NICE guideline (up to 74.26%, Sn 81.8%, Sp 73.8% PPV 15.3%) and the ACOG guideline (up to 39.6%, Sn 90.9%, Sp 36.6, PPV 7.63%). Compliance with the NICE and ACOG recommendation on aspirin administration was only 42.37% and 33.33%, respectively, and this increased to up to 62% when comprehensive first trimester screening was used. @*Conclusion@#This study confirmed that the performance of screening for PE, and therefore appropriate selection of the patients that would benefit from prophylactic use of aspirin and closer surveillance, is by far superior if the comprehensive first trimester screening is used than the method advocated by ACOG and NICE.

Research on maternal blood lipid,free fatty acid content and the neonatal lactic acid and myocardial enzyme levels in early-onset pre-eclampsia complicated gestational diabetes mellitus patients / 中国综合临床

Objective To study the changes of maternal serum lipid,free fatty acid levels and the neonatal arterial blood gas,lactic acid and myocardial enzyme levels in the patients with early-onset pre-eclampsia(EOPE) combine with gestational diabetes mellitus(GDM).Methods One hundred and fifty cases EOPE patients were divided into EOPE+GDM group(observation group,n=67) and normal glucose tolerance EOPE group(control group,n=83) according to international association of diabetic pregnancy study group standard.The maternal BMI,serum lipid(TC,TG,LDL-C,very low density lipoprotein cholesterol(VLDL-C)),free fatty acid(FFA),HbA1c levels and the blood routine and biochemical tests were compared between two groups.The neonatal peripheral arterial blood-gas,lactate(LAC) and myocardial enzymes(creatine kinase(CK),lactate dehydrogenase(LDH),creatine kinase isoenzyme(CK-MB)) levels within 1 h after birth were measured and compared between two groups.Pearson correlation analysis was used to explore the impact of maternal glucose/lipid metabolic index,the birth condition on the neonatal LAC and CK-MB levels in EOPE patients.Results (1)In observation group,the patients had significantly higher BMI((32.66±4.23) kg/m2 vs.(29.98±5.44) kg/m2,t=4.904),TC((7.28±1.34) mmol/L vs.(6.65±0.76) mmol/L,t=5.760),TG((4.10±1.26) mmol/L vs.(3.51±0.71) mmol/L,t=4.199),LDL-C((4.85±1.24) mmol/L vs.(3.77±0.82) mmol/L,t=5.292),VLDL-C((1.91±0.37) mmol/L vs.(1.26±0.48) mmol/L,t=4.498),HbA1c((5.95±0.41)% vs.(5.20±0.37)%,t=8.821) levels than control group(P<0.05),and the patients had significantly elevating levels of LAC((5.76±3.32) mmol/L vs.(3.89±1.53) mmol/L,t=5.348) and CK((419.03±198.29) U/L vs.(323.22±154.38) U/L,t=6.632),CK-MB((218.97±86.74) U/L vs.(142.18±60.12) U/L,t=5.562),LDH((723.22±180.16) U/L vs.(584.57±139.81) U/L,t=4.987)(P<0.05).(2)Stepwise multiple regression showed that in patients with early-onset preeclampsia,maternal HbA1c(β=70.821,t=5.461),FFA levels(β=88.590,t=4.990),the gestational age (β=-8.776,t=-4.901) and the neonatal LAC levels(β=5.948,t=4.047) were the independent factors of newborn's CK-MB level.Conclusion In patients with early-onset preeclampsia combine with GDM,the disorders in glucose and lipid metabolism are more severe.And the metabolic disturbance will further interfere with the perinatal material metabolism,resulting in the elevating levels of lactic acid and the potential myocardial injury in neonates.

Analysis of clinical characteristics and perinatal outcomes in pre-pregnancy obesity patients with early-onset preeclampsia / 天津医药

Objective To explore clinical characteristics and the perinatal effects of multiple systems in pre-pregnancy obesity patients with early-onset preeclampsia. Methods A total of 111 cases with early-onset preeclampsia in our Inpatient Obstetric Department were reviewed in this study. According to pre-pregnancy body mass index (BMI), patients were divided into normal before pregnancy group (BMI<28 kg/m2, n=56) and obese before pregnancy group (BMI≥28 kg/m2, n=55) . The body weight, BMI, weight gain during pregnancy, risk factors, clinical features, and clinical features of neonatal index were compared between two groups. The correlation between maternal and neonatal indexes and glucose and lipid indexes were compared. Results Obese before pregnancy was more prone to blood concentration and disorders of lipid metabolism. The serum levels of lipid, glycosylated hemoglobin (HbA1c), hematocrit, platelet and fibrinogen were significantly higher in obese before pregnancy group than than those of normal group. The induced neonatal acidosis and other organ damage, newborn Apgar score, pH, glucose were significantly lower in obese before pregnancy group than those of normal group. The residual alkali (BE), lactic acid (LAC), creatine kinase (CK) and creatine kinase (CKMB) were higher in obese before pregnancy group than those of normal before pregnancy group. Correlation analysis showed that maternal low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), three acyl glycerol (TG) and HbA 1c were negatively correlated with neonatal Apgar score and pH, and which were positively correlated with neonatal LAC and CKMB. Both differences were significant (P<0.05 or P<0.01). Conclusion The dyslipidaemia in early onset preeclampsia in obesity patients before pregnancy is closely related with maternal and perinatal outcomes.

Preeclampsia de inicio temprano y tardío: una antigua enfermedad, nuevas ideas

Las importantes diferencias que existen entre las manifestaciones de la preeclampsia, antes (inicio temprano) y después de la semana 34 (inicio tardío), plantean la posibilidad que se trate de dos enfermedades distintas. Basada en diferencias genéticas, epidemiológicas y placentarias, esta hipótesis cobra fuerza. Sin embargo, recientes estudios nos muestran la posibilidad de una continuidad clínico temporal entre ambos fenotipos. En este contexto los fenómenos antiangiogénicos y su relación con el feto podrían ser determinantes para esclarecer la interrogante.

Significant differences between preeclampsia manifestations before (early-onset) and after 34 weeks (late-onset) raise the possibility that these are two different diseases. This hypothesis is strengthened based on genetic, epidemiological and placental differences. However, recent studies show the possibility of temporal continuity between both clinical phenotypes. In this context antiangiogenic phenomena and their relation with the fetus may be crucial in clarifying this unanswered question.
