Role of cited-1 and caspase-6 expression in HELLP syndrome.

Abstract

In this study, we investigated the immunohistochemical staining of cited-1 and caspase-6 expression in the placentas of pregnant women with HELLP syndrome. Placentas of 20 normotensive patients and 20 women with HELLP syndrome were processed for routine histological tissue processing. The biochemical and clinical parameters of patients were recorded. Placentas were stained with hematoxylin-eosin and cited-1 and caspase-6 immunostaining. Placentas of normotensive patients showed normal histology. Placentas of women with HELLP syndrome showed degenerated cells, hyalinization and vacuolization. Cited-1 expression was negative in normotensive group; however, it was increased in HELLP group, especially in decidual cells, endothelial cells and other placental cells. Caspase-6 expression was negative in placental structures of normotensive groups. However, it was intense in decidual cells, vacuolar and hyalinized areas, inflammatory cells and connective tissue cells in HELLP group. Cited-1 and caspase-6 are a marker in determining the severity of HELLP syndrome.
