Longitudinal profile of high‐sensitivity C‐reactive protein in women with pre‐eclampsia

Abstract

AbstractProblemC‐reactive protein (CRP) is a marker for inflammation and its role as a possible biomarker for an early prediction of pre‐eclampsia (PE) is unclear. The present study investigates the levels of high‐sensitivity CRP (hs‐CRP) longitudinally across pregnancy in women with PE and compares them to women without PE (non‐PE).Method of StudyA total of 324 pregnant women [216 non‐PE and 108 PE women] were included in this study. Maternal blood was taken at four different intervals (V1 = 11–14 weeks, V2 = 18–22 weeks, V3 = 26–28 weeks, and V4 = at delivery).ResultsMaternal serum hs‐CRP levels were higher at V1, V2, and V3 (p < .05 for all) in the PE group compared to the non‐PE group. The hs‐CRP levels were associated with maternal blood pressure throughout pregnancy. Maternal hs‐CRP levels did not differ among early and late onset PE. Higher maternal hs‐CRP levels were associated with the increased risk of PE in unadjusted model in early pregnancy. However, there was no significance after adjusting for confounding factors.ConclusionsOur findings suggest although the levels of hs‐CRP were higher in PE in early pregnancy, they are not associated with an increased risk of PE.
