ABSTRACT

SUMMARY:

Severe preeclampsia (HELLP syndrome) is a life-threatening pregnancy complication, usually a severe form of preeclampsia. In this study, we aimed to examine histopathologic changes and Endothelin-1 and KI-67 expression levels by immunohistochemical methods in severe preeclamptic placentas. Severe preeclampsia and obstetric characteristics and biochemical and hematological characteristics of healthy subjects were compared. Placenta sections were stained with hematoxylin-eosin for histopathological examination. In the histopathological examination of severe preeclamptic placenta, degeneration in synaptic and cytotrophoblastic cells, increase in insidious knots, fibrinoid necrosis, degeneration in endothelial cells, calcification and hyaline villous stains were observed. In the severe preeclampsia group, Ki-67 expression increased in decidua cells and inflammatory cells, while endothelial cells in the vessel wall and inflammatory cells in the villus and intervillous spaces increased. It is thought that angiogenetic and cellular proliferation is induced in a co-ordinated manner and significantly influences fetal development.
RESUMEN
RESUMEN La preeclampsia severa (síndrome de HELLP) es una complicación del embarazo potencialmente mortal, generalmente una forma grave de preeclampsia. En este estudio, nuestro objetivo fue examinar los cambios histopatológicos y los niveles de expresión de Endotelina-1 y Ki-67 mediante métodos inmunohistoquímicos en placentas preeclámpsicas graves. Se compararon la preeclampsia grave y las características obstétricas, además de las características bioquímicas y hematológicas de pacientes sanas. Las secciones de placenta se tiñeron con hematoxilina-eosina para examen histopatológico. En el examen histopatológico de placenta preeclampsia severa, se observó la degeneración en células sinápticas y citotrofoblásticas, un aumento de nudos insidiosos, necrosis fibrinoide, degeneración en las células endoteliales,calcificación y manchas vellosas hialinas. En el grupo de preeclampsia grave, la expresión de Ki-67 aumentó en células deciduas y células inflamatorias, mientras que las células endoteliales en la pared del vaso, y las células inflamatorias en las vellosidades y los espacios intervellosos aumentaron. Se cree que la proliferación angiogenética y celular se induce de forma coordinada y que influye significativamente en el desarrollo fetal.
