The endocrinology of pre-eclampsia.

Pre-eclampsia is a pregnancy specific syndrome that is a principal cause of maternal morbidity and mortality, accounting for almost 15% of pregnancy associated deaths, and is one of the major causes of iatrogenic prematurity among new born babies. The mild form of pre-eclampsia most commonly presents with the features of maternal hypertension and proteinuria, but can swiftly and unpredictably become severe with numerous multisystem complications involving the maternal liver, kidneys, lungs, blood and platelet coagulation and nervous systems. The diverse symptoms of pre-eclampsia have made it a difficult disease not only to define, but also to identify a causative agent for the symptoms. This review examines the complex endocrinological mechanisms believed to be responsible for the extensive complications of pre-eclampsia from the role of placental and endothelial dysfunction, to the causes of the oxidative stress and the ensuing general inflammation. It also highlights current endocrine findings that exhibit the potential for clinical application, as either potential markers or novel therapeutic targets, with the aim of either preventing or altering the course of this life-threatening disease of pregnancy.
