EP01.07: Clinical Relevance of Angiogenic Factors in Late Onset Pre‐eclampsia
Ultrasound in Obstetrics and Gynecology(2019)
摘要
The clinical significance of sFlT1:PlGF ratio in late onset pre-eclampsia is unclear. The aim of the present study was to evaluate the relationships of this parameter with maternal and perinatal outcomes. This is a pilot prospective case-control study. In total 45 pregnant women, 16 with late onset pre-eclampsia (> 34 weeks) (8 mild and 8 severe) and 29 controls were studied. sFlT1, PlGF and ratio sFlT1:PlGF ratio was measured by immunoassay (Roche Corp). Patients were classified in mild and severe pre-eclampsia. Relationships with hematological, biochemical, Doppler parameters and perinatal outcomes were studied. Student t test, ANOVA test and Pearson's coefficient correlation were used. Statistical significance was set at 95% level (p <0.05). sFlt1 and sFlT1:PlGF ratio were significantly increased and PlGF was decreased in women with late onset pre-eclampsia in comparison to controls. Overlapping was more pronounced for PlGF than for both sFLt1 and sFlT1:PlGF ratio. There were no significant differences between mild and severe cases in the level of angiogenic factors. However, sFlT1:PlGF ratio was significantly correlated with creatinine, ALT and AST (r = 0.53, p = 0.03, r = 0.54, p = 0.03, r = 0.58, p = 0.01 respectively). In the subgroup of women with pre-eclampsia sFlT1:PlGF ratio was significantly correlated with uterine artery PI (r = 0.82, p = 0.005) and both PlGF and sFlT1:PlGf were corrlelated with birthweight in centiles (r = 0.59, p = 0.02 and r = - 0.65; p = 0.01). In women with late onset pre-eclampsia angiogenic factors may identify women with defective placentation but their relationships with maternal morbidity although present is poor. EP01.07: Table 1.
