Background: Pre-eclampsia, a syndrome of hypertension and proteinuria, is a major cause of maternal and perinatal morbidity and mortality. Accurate prediction of pre-eclampsia is important, since high risk women could benefit from intensive monitoring and preventive treatment. However, decision making is currently hampered due to lack of precise and up to date comprehensive evidence summaries on estimates of risk of developing pre-eclampsia. Methods/Design: A series of systematic reviews and meta-analyses will be undertaken to determine, among women in early pregnancy, the accuracy of various tests (history, examinations and investigations) for predicting pre-eclampsia. We will search Medline, Embase, Cochrane Library, MEDION, citation lists of review articles and eligible primary articles and will contact experts in the field. Reviewers working independently will select studies, extract data, and assess study validity according to established criteria. Language restrictions will not be applied. Bivariate meta-analysis of sensitivity and specificity will be considered for tests whose studies allow generation of 2 × 2 tables. Discussion: The results of the test accuracy reviews will be integrated with results of effectiveness reviews of preventive interventions to assess the impact of test-intervention combinations for prevention of pre-eclampsia.

    Background: Pre-eclampsia is thought to have an important genetic component. Recently, preeclampsia has been associated in some studies with carriage of a common eNOS gene Glu298Asp polymorphism, a variant that leads to the replacement of glutamic acid by aspartic acid at codon 298. Method:...

    If the negative association between pre-eclampsia and subsequent breast cancer risk differs by gender, this would strengthen the hypothesis that factors intrinsic to the particular pregnancy may explain the association. The study included 701 006 parous Norwegian women with follow-up for breast...

    Introduction: Preeclampsia is a disease whose etiology is not very clearly explained. The aim of this study was to investigate the importance of blood urea nitrogen (BUN)/creatinine ratio in diagnosing preeclampsia and evaluating prognosis.

    Background: Preeclampsia affects 3–5% of all pregnancies. It is a major cause of maternal and fetal morbidity and mortality. Recent studies demonstrate that autoantibodies against the angiotensin II type 1 (AT1) receptor are present in the serum of preeclamptic patients. In this study, we...

    Preeclampsia is a big problem in obstetrics. The diagnosis relies mainly on the detection of both hypertension and proteinuria. The gold standard for the determination of proteinuria is 24 h urinary protein creatinine ratio; however, this approach is inconvenient and it is a considerable time...
