The value of the 24-h proteinuria in evaluating the severity of preeclampsia and predicting its adverse maternal outcomes
2018
ABSTRACTBackground: To identify the 24-h proteinuria value with quantitative analysis and how it correlates with the severity of preeclampsia and subsequent adverse maternal outcomes in the Chinese population. Study design: Eleven hospitals in 10 provinces across China were chosen, in which 1,738 pregnant women complicated by hypertensive disorders of pregnancy (HDP) with the records of 24 h proteinuria were enrolled. They were allocated into four groups: patients with maximal quantified proteinuria < 0.3 g/24 h (Group 1, n = 328); patients with maximal quantified proteinuria ≥ 0.3 g/24 h and < 2.0 g/24 h (Group 2, n = 638); patients with maximal quantified proteinuria ≥ 2.0 g/24 h and < 5.0 g/24 h (Group 3, n = 353); and patients with maximal quantified proteinuria ≥ 5.0 g/24 h (Group 4, n = 419). Logistic regression analysis were conducted to assess the differences in maternal outcomes between different subgroups of 24-h proteinuria and to identify independent risk factors of adverse maternal outcomes i...
