This study aimed to investigate the serum plasmacytoma variant translocation 1 (PVT1) level in pregnant women with gestational hypertension and pre-eclampsia and its diagnostic value for diseases and its influence on pregnancy outcome. Serum PVT1 levels in 72 pregnant women with gestational hypertension, 72 pregnant women with pre-eclampsia and 71 healthy pregnant women were evaluated by RT-qPCR, and the diagnostic significance of PVT1 for gestational hypertension was verified by receiver operator characteristic (ROC) curve. The correlation between PVT1 and clinical indicators were evaluated by Pearson correlation coefficient method. Logistic regression analysis evaluated the influencing factors in the development process of gestational hypertension to pre-eclampsia. The effect of PVT1 level on pregnancy outcome was evaluated by prognostic analysis. Results showed that PVT1 level was down-regulated in gestational hypertension group compared with healthy control group, whereas PVT1 level was down-regulated more significantly in pre-eclampsia group than in gestational hypertension group. ROC curve showed that PVT1 had high diagnostic accuracy for gestational hypertension. Pearson correlation coefficient and multiple linear regression analysis showed that PVT1 was correlated with systolic blood pressure, diastolic blood pressure, interleukin (IL)-6 and tumor necrosis factor-α. Logistic regression analysis revealed that IL-6 and PVT1 were the influencing factors of gestational hypertension to pre-eclampsia transition. Moreover, prognostic analysis manifested that the incidence of fetal growth restriction in low PVT1 expression group was significantly higher than that in high PVT1 expression group. The expression level of PVT1 has a high diagnostic accuracy for gestational hypertension, and the low PVT1 expression group is more prone to fetal growth restriction.
