Preeclampsia
Possible Role of Preeclampsia/Eclampsia in
Evolution of Human Reproduction

Preeclampsia is a consequence of the defective implantation of the placenta that occurs during the second phase of trophoblastic (advanced blastocyst) invasion. There is a deep penetration into the uterine wall because of the increased energy demands of the human fetus. With preeclampsia, pregnant women exhibit increased blood pressure (gestational hypertension), and both the mother and the infant are threatened accordingly. Preeclampsia describes the symptoms that lead to eclampsia: maternal seizures and epileptic convulsions, accounting for about 70,000 deaths of women worldwide. This type of hypertensive disorder of pregnancy (HDP) is mostly associated with first pregnancies and more specifically with women who have not sexually cohabited with their male partners for a long period (4-5 months). Thus, the longer the father exchanges his body fluids with the mother, the more he exposes her to his antigens, and the less likely the disease finds expression.
Hypertensive Disorders of Pregnancy occur in approximately 10% of human births (14 million per 136 million births) worldwide. More than 95 percent of cases occur in developing countries, often resulting in death. Severe preeclampsia induces damage to the kidneys (proteinuria), where proteins from the blood (albumin in particular) leak into the urine when the filters of the kidney, called glomeruli, are damaged. Preeclampsia also induces damages to the liver (hemolysis, elevated liver enzymes, and low platelet count). These induce epileptic seizures. The only cure for any HDP is immediate delivery of the fetus and placenta. As such, preeclampsia induces fetal prematurity. HDP are on the plagues of human reproduction. There are no animal models of HDP. Eclampsia has been described in humans from different cultures as early as 4,200 years ago and associated with possession by evil spirits.

    Risk factors for placenta accreta are prior c-section and any other uterine surgeries. A presentation of placenta previa plus previous h/o other uterine surgery carries a 4% incidence of placenta accreta. In addition, a history of c-section plus a presentation of placenta previa in current pregnancy is associated with a 10-35% incidence of placenta accreta.(Uptodate) Management of placenta accreta depends on whether uterine preservation is an option or strongly desired. Two thirds of patient with a placenta accreta will require cesarean hysterectomy. Other interventions to achieve hemostasis that are packing lower segment with subsequent vaginal removal of packs in 24 hours and interrupted circular suture of lower uterine segmentation on serosal surface of uterus. If complete placenta accreta is suspected, management includes having at least 4 units of matched blood on hand, an anesthesiologist present in room, and surgical instruments sterile and ready for delivery. Hysterectomy is associated with the highest survival and lowest morbidity rate of the treatments available for placenta accreta. There are three other options that can preserve the uterus. The first option is oversewing defects after placental removal in conjunction with oxytocin and antibiotics. The second option involves localized resection of uterus and repair. The third option entails curettage of the uterine cavity. Alternative management without intervention is to leave the placenta in situ and remove at a later date, around two…

    Several studies analyzed in a landmark 2003 article in the Obstetrical and Gynecological Survey show that induced abortion also increases the risk of placenta previa by 50 percent and doubles the risk of pre-term birth in later pregnancies. Placenta previa – where the placenta implants at the bottom of the uterus and covers the cervix – places the lives of both mother and child at risk in that later pregnancy. Pre-term birth is associated with low birth-weight babies, and very low birth-weight babies (those born between 20 and 27 weeks) have 38 times the risk of having cerebral palsy – not to mention medical costs 28 times greater — than full-term babies. According to Dr. Byron Calhoun, director of the Antenatal Diagnostic Center at Rockford Memorial Hospital in Illinois, approximately 30 percent of pre-term births – which now account for 6 percent of all births — are attributable to prior abortions.…
