Abstract
Objective. Hypothesising that metabolic syndrome may be associated with or useful in the prediction of pre-eclampsia, we investigated the association between all components of metabolic syndrome and C-reactive protein (CRP) in women with and without pre-eclampsia.
Methods. A case–control study was performed. Cases had gestational hypertension or pre-eclampsia and controls were term deliveries. Clinical data and maternal serum was collected. The presence of metabolic syndrome (3/5 variables present) and a metabolic score (continuous 0–5) were investigated. Significant associations were evaluated using t-tests, and Pearson chi-square tests of association. Multivariable logistic regression was used to control for confounders.
Results. One-hundred and one cases and 267 controls were evaluated. We observed a higher odds of pre-eclampsia when metabolic syndrome was present (AOR = 2.71 [1.1–6.67], p = 0.03). For every one-unit increase in metabolic score, there was a 39% increased odds of pre-eclampsia (AOR = 1.39 [1.06–1.82], p = 0.017). The odds of pre-eclampsia were nearly four times higher when hs- CRP was >8 (AOR = 3.61 [2.14–6.12], p < 0.001).
Conclusions. Metabolic syndrome and hs-CRP are associated with pre-eclampsia. Investigation is crucial to determine if these abnormal lipid and inflammatory pathways observed in women with pre-eclampsia are present pre-pregnancy or develop as a result of the disease process of pre-eclampsia. Further investigation is also warranted to determine whether these abnormalities persist post-pregnancy and if so, their contribution to long-term cardiovascular disease.
