Association between serum beta-human chorionic gonadotropin and inflammation, oxidative stress in pregnancy-induced hypertension.

The aberrant increase of circulating beta-human chorionic gonadotropin (β-HCG) at early stages of pregnancy can be used to predict gestational hypertension. However, the association of β-HCG and inflammation, oxidative stress in pregnancy-caused hypertensive disorder on perinatal stage remains unclear. A case-controlled study was performed, with 133 adult pregnant women participated in their perinatal stage. Participants in this research included 45 with mild preeclampsia, 40 with severe preeclampsia and 48 without hypertension. Higher circulating β-HCG level was correlated with severer pregnancy-induced hypertension. Independent contribution of inflammatory factors including interleukin-6, tumor necrosis factor-α and interferon-γ and oxidative stress factors including thiobarbituric acid reactive substance and total antioxidant capacity to severe pregnancy-induced hypertension was significant (p < 0.001). The correlation of circulating β-HCG levels with inflammatory and oxidative stress markers in patients with pregnancy-induced hypertension in perinatal stage was statistically significant.
