    Abstract:
    PURPOSE: The aim of this study was to evaluate the levels of vascular endothelial growth factor (VEGF), soluble VEGF receptor-1 (sVEGFR-1) and placenta growth factor (PlGF) and VEGF/SVEGFR-1 ratio in pregnant women with threatened abortion (TA) compared to uncomplicated pregnancies at the same gestational week. METHODS: Thirty-three pregnant women with TA and thirty-three pregnant women with uncomplicated pregnancies were included in this case-control study. The level of VEGF, sVEGFR-1, and PIGF was analyzed by enzyme-linked immunosorbent assay (ELISA). The primary purpose of this study was to compare the VEGF, sVEGFR- 1, and PlGF levels and VEGF/sVEGFR-1 ratios in pregnant women with TA and pregnant women with uncomplicated pregnancies. The secondary purpose of this study was to evaluate the correlation between serum levels of these markers and gestational age. RESULTS: The serum levels of the sVEGFR-1 [0.60 (0.21-1.68) vs. 0.24 (0.09-0.57) ng/ml], VEGF [39.10 (6.57-163.56) vs. 5.24 (0.84-15.08) ng/ml] and VEGF/SVEGFR-1 ratio [68.64 (6.45-550.48) vs 24.12 (2.63-72.63)] were significantly elevated in women with TA (respectively, p: 0.001, p: 0.001, p: 0.001). However, PlGF did not elevate in women with TA [20.80 (3.13-93.11) vs 20.16 (1.22-49.91) ng/ml] (p: 0.473). CONCLUSION: These findings support the hypothesis that increased levels of the VEGF and sVEGFR-1 and VEGF/SVEGFR-1 ratio may be associated with the pathogenesis of TA.
