Abstract
The aim of this study was to investigate whether there is a new factor in the etiology of recurrent loss of pregnancy. For this purpose, serum malondialdehyde (MDA) and nitric oxide (NO) levels as indicators of oxidative stress, and endocan levels, a marker of vascular dysfunction, were investigated in patients diagnosed with habitual abortion. The research was conducted as a prospective case-control study. Patients aged 18-40 years with two or more consecutive pregnancy losses revealed by ultrasonographic or histopathological examination, and with no pathology capable of causing habitual abortion were included in the study group. Patients with no history of abortion, with at least one healthy pregnancy, who were planning pregnancies, and who presented to the outpatient clinic for routine prepregnancy tests were selected as the control group. Two groups were established-habitual abortion (n = 30) and control (n = 29). At the end of the menstrual cycle, blood samples were collected and centrifuged. Serum NO, MDA, and endocan levels were studied. Serum endocan, NO, and MDA levels were higher in women with habitual abortion compared to healthy controls. Pearson's correlation analysis revealed a positive correlation between serum endocan levels and NO and MDA levels. A positive correlation was also observed between serum MDA and NO levels. Multiple regression was run to predict serum endocan levels from MDA and NO levels. These variables emerged as statistically significant predictors of endocan. These findings suggest the presence of vascular endothelial dysfunction in patients with habitual abortion.
