We aimed to measure the concentration of selected markers of endothelial dysfunction: vascular endothelial growth factor (VEGF), endothelin-1 in pregnant women with varicose disease. This study included 63 patients diagnosed with chronic venous insufficiency in the second trimester of gestation. The disease severity was the criterion for categorizing the women into two subgroups: there were 36 women with varicose vein C1 class (according to CEAP) and 27 women with C2 class, 33 healthy pregnant women have made the control group. It was found that the concentration of endothelin-1increased along with disease severity in pregnant women with chronic venous insufficiency (CVI). A moderate positive correlation was revealed in CVI women between hs-CRP level and VEGF(r=0,34, p=0,02, n=63) as well as between hs-CRP and BMI (r=0,4, p=0,01, n=63).The results of this study demonstrate the presence of endothelial dysfunction in pregnant women suffering from CVI which seems to progress with the disease severity and may be associated with future pregnancy complications. Pregnancy 25OHD status is influenced by season. Vitamin D insufficiency is very common during the second trimester of pregnancy. Intake of vitamin D supplements may reduce pregnancy complications.
