Practical Considerations Concerning Preeclampsia Subgroups

Preeclampsia is one of the most serious clinical syndromes which can occur during pregnancy. According to our current knowledge, preeclampsia cannot be cured. However, a significant step forward is the recognizing preeclampsia is not a homogenous syndrome, i.e., different pathological events can lead to the hypertension + symptoms of organ damage, occurring in the second half of pregnancy. Clinically, two kinds of preeclampsia can be distinguished. The "classic" placental preeclampsia of immunological origin is characterized by contracted blood volume, fetal growth restriction, and marked alterations in laboratory indices. Patients in this subtype are characteristically young and primiparous. Clinical symptoms appear during the late second or early third trimester and show a quick progression. The outcome in cases of placental preeclampsia is frequently serious. For preventing the most critical conditions, the necessary delivery induction usually results in a preterm newborn. The maternal preeclampsia is associated with high blood volume. The characteristic augmented gestational weight gain is mostly a condition with a multifactorial background; however, obesity seems a critical risk factor. The early clinical symptoms are leg, and then generalized edema; hypertension and proteinuria appear after that. Laboratory abnormalities are rare; even platelet count remains within the normal range. The outcome is usually favorable; however, serious organ edema can lead to eclampsia or placental detachment. In the case of both types-from the name to the therapy-new data worthy of consideration have been created, which also justifies a change in attitude.
