Abstract
Because up to 12% of obstetric patients meet criteria for the diagnosis of thrombocytopenia in pregnancy, it is not infrequent that the anesthesiologist must decide whether to proceed with a neuraxial procedure in an affected patient. Given the potential morbidity associated with general anesthesia for cesarean delivery, thoughtful consideration of which patients with thrombocytopenia are likely to have an increased risk of spinal epidural hematoma with neuraxial procedures, and when these risks outweigh the relative benefits is important to consider and to inform shared decision making with patients. Because there are substantial risks associated with withholding a neuraxial analgesic/anesthetic procedure in obstetric patients, every effort should be made to perform a bleeding history assessment and determine the thrombocytopenia etiology before admission for delivery. Whereas multiple other professional societies (obstetric, interventional pain, and hematologic) have published guidelines addressing platelet thresholds for safe neuraxial procedures, the US anesthesia professional societies have been silent on this topic. Despite a paucity of high-quality data, there are now meta-analyses that provide better estimations of risks. An interdisciplinary taskforce was convened to unite the relevant professional societies, synthesize the data, and provide a practical decision algorithm to help inform risk-benefit discussions and shared decision making with patients. Through a systematic review and modified Delphi process, the taskforce concluded that the best available evidence indicates the risk of spinal epidural hematoma associated with a platelet count ≥70,000 × 106/L is likely to be very low in obstetric patients with thrombocytopenia secondary to gestational thrombocytopenia, immune thrombocytopenia (ITP), and hypertensive disorders of pregnancy in the absence of other risk factors. Ultimately, the decision of whether to proceed with a neuraxial procedure in an obstetric patient with thrombocytopenia occurs within a clinical context. Potentially relevant factors include, but are not limited to, patient comorbidities, obstetric risk factors, airway examination, available airway equipment, risk of general anesthesia, and patient preference.

Abstract
Studies lack data regarding incidence, risk factors, optimal treatment and outcome of postpartum eclampsia (PPE), convulsions within 7 days (mostly convulsions occur within 24 - 48 h) after delivery of fetus placenta. However, convulsions can occur late, up to 4 weeks. After 48 h, it is late PPE. Late postpartum eclampsia without preceding pre-eclampsia is rare and poses a diagnostic challenge. An observational study was carried out to find the frequency of PPE, late PPE and clinical profile for prediction/prevention of mortality. PPE cases were analysed from retrospective records and prospective cases. Of 39,050 births, 386 were eclampsia (0.98%); PPE 101 (26.1% eclampsia, 0.26% births); 14.85% were late PPE. Of PPE, 52 (51.48%) were diagnosed hypertensive disorders pre-delivery and 49 (48.51%) were de novo. Prior to convulsions, 56 (55.5%) had headaches, six (5.9%) visual disturbances; nine (8.9) dizziness; four (4.0%) epigastric pain; 18 (17.8%) had no complaints. Research needs to continue and quality care is essential.

Abstract
Thrombotic microangiopathies (TMAs) are syndromes associated with thrombocytopenia and multiple organ failure. Plasma exchange is a proven therapy for primary TMA such as thrombotic thrombocytopenic purpura (TTP). There is growing evidence that plasma exchange therapy might also facilitate resolution of organ dysfunction and improve outcomes for secondary TMAs such as disseminated intravascular coagulation (DIC) and systemic inflammation-induced TTP. In this review, we survey the current available evidence and practice of plasma exchange therapy for TMAs.

Abstract
The spectrum of complications with pre-eclampsia, which may include AFLP (acute fatty liver of pregnancy) as well as the HELLP syndrome (hemolysis, elevated liver enzymes, and low platelets), is resolved by early delivery. However, the ravages of HUS/TTP (hemolytic uremic syndrome/thrombotic thrombocytopenic purpura) require therapy usually by plasma exchange. Overlap between these two groups of syndromes has occurred on rare occasions and usually requires the therapy of the predominant or more dangerous or threatening form. Such overlap can be appreciated and then treated successfully without residual morbidity. The index case is presented and an extensive review of the two groups of syndromes is provided.

Abstract
OBJECTIVE To identify symptoms that prompted a group of women readmitted for postpartum severe preeclampsia or eclampsia to seek medical care. DESIGN Retrospective, case-control. SETTING Tertiary-care teaching hospital. SUBJECTS The study group consisted of 53 women readmitted in the postpartum period with severe preeclampsia or eclampsia. The control group was matched two-to-one with an index study participant and consisted of 106 women who had intrapartum severe preeclampsia or eclampsia. MAIN OUTCOME MEASURES Patient symptoms, physical findings, laboratory assays. RESULTS Neurologic complaints, malaise, and nausea and vomiting were reported more often in women who were readmitted than in mothers with intrapartum preeclampsia (all p values less than .001). Headaches were positively correlated with systolic, diastolic, and mean arterial blood pressure in women who were readmitted (all p values less than .05), although there was no relationship between blood pressure and headaches in the control group. In addition, multivariate analysis revealed that study participants were more likely to deliver at full term, have headaches and malaise, have normal platelet values, and develop seizures than mothers in the control group, chi 2 = 155.7, p < .001. CONCLUSIONS Women readmitted for postpartum severe preeclampsia or eclampsia have a clinical presentation that differs from that of intrapartum preeclampsia or eclampsia.

Abstract
Preeclampsia has been recognized clinically since the time of Hippocrates: however its etiology and pathophysiology remain enigmatic. This pregnancy-specific syndrome typically presents in late pregnancy as hypertension, edema, and proteinuria. Investigations over the past 15 years have revealed that preeclampsia is associated with abnormal placentation, reduced placental perfusion, endothelial cell dysfunction, and systemic vasospasm. Since it occurs more commonly in primigravidae and in women with underlying collagen-vascular diseases, an immunological component has long been suspected. Increased prevalence in high-order and molar pregnancies and those associated with increased placental mass suggests that trophoblastic volume and fetal antigen load are correlated with the syndrome. Epidemiological reports indicate that the prevalence of preeclampsia is decreased in women who received heterologous blood transfusions, practiced oral sex, or when a long period of cohabitation preceded an established pregnancy. Conversely, the use of condoms as a primary mode of contraception is associated with a higher risk of preeclampsia. These studies suggest that prior exposure to foreign or paternal antigens imparts a protection against the likelihood of developing preeclampsia. Clinical evidence of cellular and humoral immune dysfunction is associated with the syndrome. Fibrin and complement deposition and "foam" cells in atherosis lesions resemble the histopathology of renal allograft rejection. Relative T-cell, natural killer cell, and neutrophil activation have been reported in preeclampsia and circulating cytokines and antiphospholipid antibodies are more prevalent in preeclampsia than in normal pregnant women. These abnormalities are consistent with the systemic endothelial cell dysfunction that has been postulated as a pathophysiological feature of preeclampsia. While such associations do not prove causality, they suggest testable hypotheses for continued basic and clinical investigation of this major complication of human pregnancy.

Abstract
OBJECTIVE Our purpose was to investigate the postpartum use of plasma exchange in patients considered to have atypical preeclampsia-eclampsia manifested as persistent HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome with or without evidence of other organ injury. STUDY DESIGN During a 10-year period, 18 patients with HELLP syndrome were treated post partum with single or multiple plasma exchange with fresh-frozen plasma. Each patient was entered into the clinical trial either because of persistent evidence of atypical preeclampsia-eclampsia as HELLP syndrome > 72 hours after delivery (group 1) or with evidence of worsening HELLP syndrome at any time post partum in association with single- or multiple-organ injury (group 2). All procedures were performed with the IBM 2997 Cell Separator (IBM, Cobe Laboratories, Inc., Lakewood, Colo.) system. Maternal and perinatal outcomes were the main outcomes studied. RESULTS In the absence of other disease conditions, the 9 patients in group 1 with persistent postpartum HELLP syndrome complicated only by severe clinical expressions of preeclampsia-eclampsia responded rapidly to one or two plasma exchange procedures with few complications and no maternal deaths. In contrast, in the 9 patients of group 2 with HELLP syndrome presentations complicated by other organ disease, the response to plasma exchange was variable and there were two deaths in this group. CONCLUSION The current series of patients details the successful postpartum application of plasma exchange therapy for unremitting HELLP syndrome but reveals that a uniformly positive response to this therapy will not always be observed when there is additional single or multiple organ injury.

Abstract
To evaluate changes in feto-placental markers with plasma exchange in pregnancy, two patients at varying stages of pregnancy referred to a tertiary care hospital and requiring plasma exchange for intercurrent problems were evaluated. Alpha-fetoprotein, human chorionic gonadotropin, and free estriol were sequentially measured in the patients' plasma and in the fluid removed, thus permitting calculations of permeability rates and clearances. Despite markedly different molecular weights, all three feto-placental markers had similar permeabilities and clearances. While in both patients maternal levels of alpha-fetoprotein and human chorionic gonadotropin decreased rapidly with plasma separation and rebounded rapidly to baseline, free estriol responded differently and did not appear to decrease with therapy. Maternal levels of feto-placental markers only transiently changed with plasma exchange during pregnancy and rapidly returned to baseline with no apparent consequences to the pregnancy.

Abstract
OBJECTIVE To explore the potential efficacy of plasma exchange as an ancillary interventive therapeutic tool immediately before or after delivery in the patient with severe preeclampsia/eclampsia and hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. STUDY DESIGN Two gravidas with complicated severe preeclampsia/eclampsia/HELLP syndrome were treated emergently in the immediate peripartal period with single-volume plasma exchange and fresh frozen plasma fluid replacement using the IBM 2997 Cell Separator. RESULTS Despite multiple platelet unit infusions, one primigravida in active labor at 5 cm cervical dilation and 39 weeks' gestation remained at a platelet count of 14,000/microL and began to ooze from her guns. A second primigravida remained obtunded, oliguric, and thrombocytopenic with epistaxis and hematuria following cesarean delivery and platelet transfusions. A single expedited 3-liter plasma exchange procedure reversed the rapidly deteriorating clinical situation for each patient and accelerated recovery from HELLP syndrome. Both patients and progeny suffered no permanent sequelae. CONCLUSION Based on our experience, we believe that the therapeutic modality of plasma exchange with fresh frozen plasma can be employed effectively for the pregnant patient with severe atypical HELLP syndrome that progressively worsens during labor or the early puerperium despite the use of conventional transfusion therapy.

Abstract
We report our apheresis department's experience with four patients with HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome. The average age of the patients was 23.25 years (range 19-27). Three were in their second pregnancy while one was a primigravida. All had symptoms of pre-eclampsia prior to delivery. All experienced the syndrome postpartum. Plasma exchange was instituted an average of 3.25 days postpartum (range 1.08-7.33 days). All underwent plasmapheresis with fresh frozen plasma replacement. The average number of plasma exchange treatments was four (range 1-8). The first laboratory parameter to reach its peak/nadir was the aspartate aminotransferase (AST), followed by the lactate dehydrogenase (LDH) enzyme level, followed by the hemoglobin (HGB) level, and, finally, the platelet count (PLT). The AST was the first parameter to peak and the first to normalize. In the three cases in which more than one plasmapheresis procedure was performed, plasmapheresis was required for an average of 98 hours (range 39-206 hours) after a normal AST level was obtained in order to achieve a self-sustaining platelet count of > or = 100 x 10(9)/L. No additional exchanges were required to maintain the PLT once a PLT of over 100 x 10(9)/L was attained. The laboratory values normalized in the following order: AST, HGB, PLT, and LDH. Three patients were discharged anemic. One was discharged with a normal LDH level. By our experience, awaiting normal LDH levels as an indicator for cessation of plasma exchange therapy would mean subjecting the patients to many unnecessary procedures.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE To explore the efficacy of plasmapheresis/plasma exchange as the primary therapy to arrest and reverse the progression of severe preeclampsia with or without HELLP syndrome in order to postpone delivery and improve perinatal outcome in very preterm pregnancies. STUDY DESIGN In this case series of patients managed over a 4-year period from 1984 to 1987, seven gravidas with severe preterm preeclampsia underwent 1-2 plasmaphereses/plasma exchange procedures using the IBM 2997 Cell Separator with continuous electronic fetal heart rate monitoring (n = 7 patients) and central cardiovascular monitoring (n = 3 patients). RESULTS The seven patients (one with HELLP syndrome, six without HELLP) presented between 24 and 30 weeks gestation and, despite plasmapheresis/plasma exchange, the severity of each study subject's preeclampsia persisted without clinically significant improvement. Maternal-fetal deterioration required cesarean delivery in all cases within 48 (in four patients within < 36) hours of therapy. No clinically significant adverse effect of plasma exchange therapy was recorded during cardiovascular and laboratory monitoring; two fetuses developed repetitive late decelerations during exchange despite adequate maternal fluid preload. The only patient with HELLP syndrome developed eclampsia as her third plasma exchange within 25 hours was being initiated. Significant problems with fluid retention and displacement (variable amounts of pulmonary edema, pleural effusions, large volume ascites) were encountered in all patients. Four neonates died (24-27 weeks/438-820 g) and three survived intact (740, 950, and 1,280 g). One mother (case 5) developed end-stage renal disease 21 months postpartum. CONCLUSIONS The application of plasmapheresis/plasma exchange therapy as described in order to prolong very preterm pregnancies in the undelivered patient with severe preeclampsia/eclampsia with or without HELLP syndrome did not produced encouraging results. Patients in general were exposed to additional medical and surgical risk without a corresponding improvement in perinatal outcome.
