We aimed to investigate the relationship between pendrin immunostaining intensity in normal and pre-eclamptic placental tissue. Methods: Fifty-six placental tissues, of which 26 were in pre-eclamptic, and 30 were in control group were evaluated by immunohistochemical staining. Positive immunostaining was evaluated using a semiquantitative score: 0, negative; +, mild; ++, moderate; and +++, intense. Results: There was more positive immunstaining in the pre-eclamptic placenta compared to the controls (p<0.001). A significant positive correlation was observed between immunostaining level and diastolic blood pressure (r = 0.533, p = 0.005) in the pre-eclamptic group. However, no significant correlation was observed between any condition and immunostaining level in the control group. Conclusions: Placentas in the pre-eclamptic group were significantly more immunostained with pendrin than were those in the control group. In addition, a positive correlation between immunostaining intensity with pendrin and both systolic and diastolic blood pressure were observed. Pendrin may play a role in the mechanism of severe hypertension in women with pre-eclampsia.eninfo:eu-repo/semantics/closedAccessPendrinPlacentaPre-eclampsiaArticle10.3109/14767058.2013.833600277687690239414062-s2.0-84897479501Q2WOS:000333583100007Q3
