Intrauterine Retardation Clinical Trial
Official title:
Comparison of Umbilical Cord Blood Levels of Endocan in Pregnant Females With and Without Intrauterine Growth Retardation
As a proteoglycan secreted from endothelial cells, expression, and secretion of endocan increases in the endothelium of several tissues secondary to inflammation. It can be regarded as an indicator of endothelial damage. Besides, it is both a target and a modulator of the vascular endothelial growth factor (VEGF) signaling pathway. Considering its action mechanisms, it can provide information about angiogenesis, inflammation, and vascular permeability. It is known that intrauterine growth retardation mainly occurs as a result of endothelial dysfunction and abnormal angiogenesis in the placenta. In previous studies, maternal serum endocan levels have also been shown to be increased in cases of preeclampsia, which is mainly characterized by placental dysfunction.So, we hypothesize that there may be an association between endocan levels and intrauterine growth retardation.
Endocan is a proteoglycan that is closely associated with inflammation. Its levels increase in association with the severity of endothelial damage. Endothelial dysfunction and abnormal angiogenesis in the placental tissues are the main pathophysiological mechanisms leading to intrauterine growth retardation. It has been known that there was a significant association between maternal serum levels of endocan and preeclampsia. In cases with preeclampsia, increased serum levels of endocan in maternal blood samples has been reported. Intrauterine growth retardation is a situation in which endothelial dysfunction and abnormal angiogenesis are the leading disturbances. In fetuses with intrauterine growth retardation, a hypoxic environment secondary to uteroplacental insufficiency. In previous studies, increased levels of endocan in maternal blood samples have been shown. Although maternal blood can be a good reflector of situations both in fetuses and their mothers, measurement of endocan in umbilical cord blood samples may better represent the pathology in fetuses. ;
