Resumo
This study aimed to evaluate soluble endoglin (sEng) in urine as a preeclampsia predictor. Ninety-three pregnant women at risk for preeclampsia were followed. Spot urine sample ELISA analysis before 20 weeks of gestation was done to assess protein levels. Logistic regression analysis evaluated associations between preeclampsia with sEng/creatinine ratio, pg/mg, adjusted for risk factors. Preeclampsia incidence was 22.8% (20/92). Urinary sEng/creatinine (pg/mg) 0.001 (95% CI 0.001–0.136) was associated, adjusted for body mass index > 28 kg/m2 OR 6.44 (95% CI 1.11–37.47) and mean arterial pressure OR 1.20 (1.07–1.35). During the first half of gestation sEng urinary excretion was lower in pregnant women developing preeclampsia.IMPACT STATEMENT: What is already known on this subject? The angiogenesis factors present in the plasma of pregnant women have shown good preclinical predictors of preeclampsia. Studies on urinary markers in pregnancy are infrequent, despite the ease of obtaining urine specimens. What do the results of this study add? Values of the sEng/creatinine ratio during the first half of pregnancy were related to a higher chance of preeclampsia occurring when it was evaluated alone or adjusted by body mass index and mean arterial pressure values. What are the implications of these findings for clinical practice and/or further research? The potential benefits of a urinary test compared to one of the blood levels include its non-invasive nature and ease of performing the test, even during prenatal care. Future research is expected to
evaluate the sEng/creatinine ratio relevance to improve clinical scores of preeclampsia prediction for the identification of women at risk for this disease.
