Abstract
Reproductive success consists of a sequential events chronology, starting with the ovum fertilization, implantation of the embryo, placentation, and cellular processes like proliferation, apoptosis, angiogenesis, endocrinology, or metabolic changes, which taken together finally conduct the birth of healthy offspring. Currently, many factors are known that affect the regulation and proper maintenance of pregnancy in humans, domestic animals, or rodents. Among the determinants of reproductive success should be distinguished: the maternal microenvironment, genes, and proteins as well as numerous pregnancy hormones that regulate the most important processes and ensure organism homeostasis. It is well known that white adipose tissue, as the largest endocrine gland in our body, participates in the synthesis and secretion of numerous hormones belonging to the adipokine family, which also may regulate the course of pregnancy. Unfortunately, overweight and obesity lead to the expansion of adipose tissue in the body, and its excess in both women and animals contributes to changes in the synthesis and release of adipokines, which in turn translates into dramatic changes during pregnancy, including those taking place in the organ that is crucial for the proper progress of pregnancy, i.e. the placenta. In this chapter, we are summarizing the current knowledge about levels of adipokines and their role in the placenta, taking into account the physiological and pathological conditions of pregnancy, e.g. gestational diabetes mellitus, preeclampsia, or intrauterine growth restriction in humans, domestic animals, and rodents.

Abstract
BACKGROUND HELLP syndrome (hemolysis, elevated liver enzymes, low platelets) is an obstetric complication with heterogonous presentation and multisystemic involvement. It is characterized by microangiopathic hemolytic anemia, elevated liver enzymes by intravascular breakdown of fibrin in hepatic sinusoids and reduction of platelet circulation by its increased consumption. METHODS In terms of these patients' anesthetic management, it is essential to consider some details: (1) effective, safe perioperative management by a multidisciplinary approach, and quick, good communication among clinical specialists to achieve correct patient management; (2) neuroaxial block, particularly spinal anesthesia, is the first choice to do the cesarean if there is only moderate, but not progressive thrombocytopenia; (3) if a general anesthesia is required, it is necessary to control the response to stress produced by intubation, especially in patients with either severe high blood pressure or neurological signs, or to prevent major cerebral complications; (4) invasive techniques, e.g., as tracheostomy, arterial, and deep-vein canalization, should be considered; (5) if contraindication for neuroaxial anesthesia exists, rapid sequence intubation with general anesthesia should be regarded as an emergency in patients with full stomach; (6) increased risk of difficult airways should be taken into account. RESULTS Optimal patient management can be chosen after considering the risks and benefits of each anesthetic technique, and based on good knowledge of these patients' pathophysiological conditions. CONCLUSION Later, close patient monitoring is recommended for potential development of hemorrhagic complications, disseminated intravascular coagulation (DIC), or eclampsia.

Abstract
BACKGROUND Hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome is one of the most severe forms of preeclampsia and aggravates both maternal and perinatal prognosis. The systematic review available in Cochrane Library compared corticosteroid (dexamethasone, betamethasone, or prednisolone) given during pregnancy, just after delivery or in the postnatal period, or both before and after birth, with placebo or no treatment. Those receiving steroids showed significantly greater improvement in platelet counts which was greater for those receiving dexamethasone than those receiving betamethasone. There was no clear evidence of any effect of corticosteroids on substantive clinical outcomes. These benefits appear to be greater in Class I HELLP syndrome. OBJECTIVES To determine the effectiveness of dexamethasone for accelerating postpartum recovery in patients with Class I HELLP syndrome in a multicenter randomized controlled trial. METHODS/DESIGN The study is a triple blind randomized controlled trial including women with class I HELLP syndrome, and exclusion criteria were dexamethasone use in the last 15 days before diagnosis of HELLP syndrome; chronic use of corticosteroids; chronic diseases that alter laboratory parameters of HELLP Syndrome, such as chronic liver disease or purpura, patients unable to consent (coma or critical clinical condition) and without accompanying persons that may consent to study participation.Eligible patients will be invited to participate and those who agree will be included in the study and receive placebo or dexamethasone according to a random list of numbers and subjects will receive the study medication every 12 hours for two days.During the study the women will be subject to strict control of blood pressure and urine output. Laboratory tests will be performed at regular intervals during treatment and 24 hours and 48 hours after its suspension. If worsening of clinical or laboratory variables is observed, a rescue scheme of dexamethasone will be administrated. This proposal has already obtained approval of the local Institutional Review Board of the coordinating center (IMIP, Recife, Brazil), all other participating centers and of the National Council for Ethics in Research (CONEP) of the Brazilian Ministry of Health. TRIAL REGISTRATION Clinical Trials Register under the number NCT00711841.

Abstract
Eisenmenger's syndrome is characterized by a right-to-left or bidirectional shunt in congenital heart diseases. Hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome, commonly occurring during pregnancy, includes hemolysis, elevated liver enzymes and low platelet counts. HELLP syndrome and pregnancy are extremely rare in patients with Eisenmenger's syndrome. The authors report 4 cases of pregnancy complicated by the HELLP and Eisenmenger's syndrome and describe their initial intervention and the in-hospital outcomes of these cases. Special emphasis is given to elaborate about the hemodynamic monitoring, magnesium sulphate for convulsions, corticosteroid treatment, anticoagulation therapy, management of pulmonary hypertension, the timing of delivery, and blood product transfusion.

Abstract
HELLP (Hemolysis Elevated Liver Enzymes and Low Platelets) syndrome is a multi-system pregnancy associated disorder, commonly seen in patients with pre-eclampsia but can occur alone. It is significantly associated with maternal-fetal morbidity and mortality.
A triad of hemolysis elevated liver enzymes and thrombocytopenia after 24 weeks of gestation is diagnostic of this syndrome. HELLP syndrome is classified depending on simple parameters but it dictates severity of the disease. Frequently encountered complications with HELLP syndrome are hemorrhagic stroke, disseminated intravascular coagulation, pulmonary edema, acute renal failure and hepatic rapture. The aggressive supportive care of failing organs with high dose of steroids will decrease the duration of HELLP syndrome, decreases intensive care and hospital stay of these patients as well as reduction in fetal complications. HELLP syndrome is associated with significant increase in morbidity and mortality of pregnant patients; hence it is of vital importance that not only obstetrician, but acute care physicians and intensivist should be aware of this clinical entity. We report a case of Classl, normotensive postpartum HELLP syndrome complicated by pulmonary edema and acute renal failure, successfully managed in our intensive care unit.

Abstract
Management of immune thrombocytopenia in pregnancy can be a complex and challenging task and may be complicated by fetal-neonatal thrombocytopenia. Although fetal intracranial hemorrhage is a rare complication of immune thrombocytopenia in pregnancy, invasive studies designed to determine the fetal platelet count before delivery are associated with greater risk than that of fetal intracranial hemorrhage and are discouraged. Moreover, the risk of neonatal bleeding complications does not correlate with the mode of delivery, and cesarean section should be reserved only for obstetric indications.

Abstract
Preeclampsia, eclampsia, and HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome remain as major obstetric problems that plague a large percentage of women resulting in an equally large percentage of maternal and perinatal morbidities. It is important that a clinician makes the most accurate diagnosis possible to prevent these adverse maternal and perinatal outcomes. In general, most women will have a classical presentation of preeclampsia (hypertension and proteinuria) at >20 weeks gestation and <48 hours postpartum. However, recent studies have suggested that some women will develop preeclampsia without the classical findings. The purpose of this review is to increase awareness of the non-classical and atypical features of preeclampsia, eclampsia, and HELLP syndrome and their respective management. Atypical cases are those that develop before 20 weeks, beyond 48 hours postpartum and those that present with some of the signs and symptoms of preeclampsia without the usual hypertension or proteinuria. By formulating a rational stepwise approach towards diagnosis, we may prevent the costly consequence of a missed diagnosis and its eventual possible fatalities.

Abstract
Gastrointestinal complications of pre-eclampsia can occur and have the risk of being life-threatening for the mother and fetus. Hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome has been recognized as a complication of pre-eclampsia for decades. Pregnancies complicated by this syndrome require a well-formulated management plan, including assessing and stabilizing the maternal condition as well as evaluating fetal well-being. Patients with HELLP syndrome should receive anti-seizure prophylaxis with magnesium sulfate, treatment for severe hypertension, and correction of coagulopathy, if present. The potential benefits of expectant management of HELLP syndrome in those remote from term and the use of corticosteroids to improve maternal outcome remain experimental. Computed tomography or ultrasound of the abdomen should be performed if a subcapsular hematoma of the liver is suspected. If a ruptured hematoma is confirmed, massive transfusions and laparotomy are indicated. Ischemia associated with pre-eclampsia cannot only damage the liver but also the pancreas and gallbladder.

Abstract
BACKGROUND The HELLP syndrome is a serious complication in pregnancy characterized by haemolysis, elevated liver enzymes and low platelet count occurring in 0.5 to 0.9% of all pregnancies and in 10-20% of cases with severe preeclampsia. The present review highlights occurrence, diagnosis, complications, surveillance, corticosteroid treatment, mode of delivery and risk of recurrence. METHODS Clinical reports and reviews published between 2000 and 2008 were screened using Pub Med and Cochrane databases. RESULTS AND CONCLUSION About 70% of the cases develop before delivery, the majority between the 27th and 37th gestational weeks; the remainder within 48 hours after delivery. The HELLP syndrome may be complete or incomplete. In the Tennessee Classification System diagnostic criteria for HELLP are haemolysis with increased LDH (> 600 U/L), AST (>or= 70 U/L), and platelets < 100 x 10(9)/L. The Mississippi Triple-class HELLP System further classifies the disorder by the nadir platelet counts. The syndrome is a progressive condition and serious complications are frequent. Conservative treatment (>or= 48 hours) is controversial but may be considered in selected cases < 34 weeks' gestation. Delivery is indicated if the HELLP syndrome occurs after the 34th gestational week or the foetal and/or maternal conditions deteriorate. Vaginal delivery is preferable. If the cervix is unfavourable, it is reasonable to induce cervical ripening and then labour. In gestational ages between 24 and 34 weeks most authors prefer a single course of corticosteroid therapy for foetal lung maturation, either 2 doses of 12 mg betamethasone 24 hours apart or 6 mg or dexamethasone 12 hours apart before delivery. Standard corticosteroid treatment is, however, of uncertain clinical value in the maternal HELLP syndrome. High-dose treatment and repeated doses should be avoided for fear of long-term adverse effects on the foetal brain. Before 34 weeks' gestation, delivery should be performed if the maternal condition worsens or signs of intrauterine foetal distress occur. Blood pressure should be kept below 155/105 mmHg. Close surveillance of the mother should be continued for at least 48 hours after delivery.

Abstract
INTRODUCTION HELLP syndrome is a variant of pregnancy-induced hypertension that is associated with significant maternal and perinatal morbidity and mortality. The aim of our study was to investigate the neonatal complications associated to this syndrome. PATIENTS AND METHOD A retrospective observational study was carried out on all newborns of mothers with HELLP syndrome in Virgen del Rocio hospital from 1995 to 2005. There were 120 newborns of 99 mothers with HELLP syndrome. Gestational age, birth weight, length, skull perimeter, number of hospital admissions and mortality were analyzed. The birth weight, length and skull perimeter were compared with a healthy population of the same gestational age using Lubchenco charts. The statistical relationships were determined between the mothers' platelet counts and the birth weight and perinatal mortality. RESULTS A total of 80% of pregnancies were preterm delivery with a mean gestational age of 33 weeks. Mean birth weight was 1,834g, length 41cm and skull perimeter 29cm. A third of newborns had fetal growth restriction. 61% of newborns needed admitting to hospital due to prematurity and low birth weight. There were 24 perinatal deaths. We did not find any correlation between the number of platelets of the mother and birth weight or perinatal mortality. CONCLUSIONS HELLP syndrome is an uncommon but potentially serious complication of pregnancy which is associated with an increased risk of adverse maternal and fetal outcome.

Abstract
OBJECTIVES Platelets and transforming growth factor-beta(1) (TGF-beta(1)) are thought to be involved in the pathogenesis of preeclampsia. Our objectives were to determine plasma concentration of TGF-beta(1) in normotensive and preeclamptic women in the third trimester of pregnancy and to evaluate the correlation of TGF-beta(1) plasma levels with platelet count and agonist-induced aggregation capacity. METHODS Thirty-three women with preeclampsia were compared with 36 healthy women with uncomplicated pregnancies. Peripheral venous blood samples were obtained, and TGF-beta(1) plasma levels measured by an enzyme-linked immunoassay. Platelet aggregation was induced by the agonist agents adenosine diphosphate (ADP), collagen and epinephrine, and was determined in platelet-rich plasma by aggregometry. RESULTS Plasma concentrations of active TGF-beta(1) were significantly higher in preeclamptic women (10.41+/-2.07ng/mL) compared with normotensive pregnant women (7.01+/-3.29ng/mL). Platelet number and platelet agonist-induced aggregation percent were significantly lower in patients with preeclampsia than in healthy pregnant women. A significant correlation was observed between TGF-beta(1) plasma levels and platelet agonist-induced aggregation percent as between plasma levels of TGF-beta(1) and platelet number in preeclamptic patients. CONCLUSION The association between impairment in platelet responsiveness and higher levels of TGF-beta(1) in the plasma of patients with preeclampsia suggests that this cytokine may play a role in the pathophysiological events of preeclampsia that are dependent on platelet activation.

Abstract
OBJECTIVE The purpose of this study was to determine the effectiveness of postpartum dexamethasone in patients with hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome. STUDY DESIGN A prospective, randomized, double-blind trial was conducted in which 105 women with HELLP syndrome were enrolled and assigned randomly to treatment or placebo groups following delivery. Duration of hospital stay, maternal morbidity, and laboratory and clinical parameters were evaluated. RESULTS There was no difference in maternal morbidity or mortality between the 2 groups. There was also no difference in duration of hospitalization and the need for rescue scheme or the use of blood products between groups. Linear model adjustments showed no significant difference between groups with respect to the pattern of platelet count recovery, aspartate aminotransferase, lactate dehydrogenase, hemoglobin, or diuresis. CONCLUSION These findings do not support the use of dexamethasone in the puerperium for recovery of patients with HELLP syndrome.

Abstract
OBJECTIVE To study the hematological profile of mothers with pregnancy induced hypertension and their infants. METHODS The effects of maternal hypertension on the hematological profile of neonates were studied in 50 cases comparing the values with that of infants born to normotensive mothers. RESULTS There was higher number of preterm, Intra-Uterine Growth Restriction (IUGR) and Small for Gestational Age (SGA) babies among the infants of hypertensive mothers. There was a significantly higher incidence of thrombocytopenia and nucleated RBCs seen in these babies. Significant neutropenia was not documented and there was no increased incidence of bleeding when compared to controls. CONCLUSION Although there were significant changes in the hematological profile of infants born to hypertensive mothers, there was no significant increase in neonatal morbidity as a result of these changes.

Abstract
Antepartum or postpartum HELLP syndrome constitutes an obstetric emergency that requires expert knowledge and management skills. The insidious and variable nature of disease presentation and progression challenges the clinician and complicates consensus on universally accepted diagnostic and classification criteria. A critical review of published research about this variant form of severe preeclampsia, focused primarily on what is known about the pathogenesis of this disorder as it relates to patient experience with corticosteroids for its management, leads to the conclusion that there is maternal-fetal benefit realized when potent glucocorticoids are aggressively used for its treatment. Although acknowledging the need for definitive multicenter trials to better define the limits of benefit and the presence of any maternal or fetal risk, and given an understanding of the nature of the disorder with its potential to cause considerable maternal morbidity and mortality, we recommend for the present that aggressively used potent glucocorticoids constitute the cornerstone of management for patients considered to have HELLP syndrome.

Abstract
Corticosteroids are potent antiinflammatory and immunosuppressive drugs, which are used in the treatment of a wide range of medical disorders. During pregnancy, several corticosteroids are administered for maternal as well as fetal reasons. Prednisone and prednisolone show limited transplacental passage and are thus used for treatment of maternal disease. Dexamethasone and betamethasone, drugs that can easily cross the placenta, are more suitable for fetal indications. During the last decade, administration of corticosteroids was introduced in the treatment of hemolysis, elevated liver enzymes, and low platelets (HELLP syndrome), a severe form of preeclampsia unique to human pregnancy. Several randomized, controlled trials as well as other prospective and retrospective studies have been performed to investigate this beneficial effect of corticosteroids on biochemical measures and clinical signs. This review discusses the characteristics of corticosteroids in humans and details the use of corticosteroids during pregnancy. A review of literature on the effect of corticosteroids on HELLP syndrome is given and possible mechanisms of action are discussed.

Abstract
Pregnancies complicated by hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome require a well-formulated management plan. The development of this syndrome after 34 weeks' gestation or with documentation of maternal or fetal compromise is an indication for delivery. Acute fatty liver of pregnancy, hemolytic uremic syndrome, and thrombotic thrombocytopenic purpura may present with signs, symptoms, and laboratory abnormalities that may be confused with HELLP syndrome. Thorough investigation is warranted because of the differences in proper management among these various complications of pregnancy. Expectant management in patients with HELLP syndrome remote from term and the use of corticosteroids to improve postpartum maternal outcome remain experimental.

Abstract
The hypertensive diseases of pregnancy commonly refer to a group of disorders whose definitions have changed over time within and among professional organizations. Pre-eclampsia, either mild or severe, is managed best with a policy of delivery at or beyond 37 and 34 weeks' gestation, respectively. Similarly, chronic hypertension,gestational hypertension, and chronic hypertension with superimposed pre-eclampsia are conditions wherein it is difficult to justify expectant management beyond 37 weeks' gestation. The approach to management before these gestational ages is subject to interpretation of a limited body of literature.

Abstract
OBJECTIVE To investigate maternal-fetal outcome of infants born after pregnancies complicated by (H)ELLP syndrome. STUDY DESIGN A retrospective cohort study was performed on patients with the HELLP or ELLP syndrome. Maternal and perinatal complications were recorded. The follow-up period of the infants was at least 18 months. A multivariate regression analysis was done to define the variables mostly contributing to adverse outcome. RESULTS No maternal deaths occurred. Eighteen infants of the HELLP group and six infants of the ELLP group died; total perinatal mortality was 17.6%. After 18 months four infants had major handicaps, making a total adverse outcome of 22.8%. Statistical analysis shows early gestational age, prolongation of pregnancy and administration of antihypertensive medication as the factors influencing outcome of the infants most. CONCLUSIONS Prolongation of pregnancy contributed to better perinatal outcome, while administration of antihypertensive medication and early gestational age were related to a more unfavorable outcome.

Abstract
OBJECTIVES To determine the more effective regime in improving hematologic abnormalities associated with HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome, by comparing two different antenatal dosing protocols for dexamethasone (given primarily for fetal lung maturity). STUDY DESIGN A retrospective cohort study of 30 women between 24 and 34 weeks' gestation, diagnosed with HELLP syndrome prior to delivery, who received 2 doses of dexa-methasone 12 mg intramuscularly, given either 24 hours apart or 12 hours apart. RESULTS There was a shorter time from the first corticosteroid dose to the beginning of improvement with the 12-hour regime for platelet count (11 hours [9, 25 hours] versus 69 hours [41, 112 hours], median [quartiles], P = 0.003) and for alkaline phosphatase (25 hours [5, 44 hours] versus 59 hours [31, 69 hours], median [quartiles], P = 0.02). Worsening recurred from 11 hours, for alanine aminotransferase (ALT) and aspartate transaminase (AST), to 32 hours, for uric acid, after initial improvement. Hematologic improvement occurred in 37% (for ALT) to 67% (for alkaline phosphatase) of women overall. CONCLUSION A temporary improvement in the hematologic parameters of HELLP syndrome can occur with antenatal dexa-methasone administration, with the 12-hour regime having quicker onset to improvement in platelet count and alkaline phosphatase.

Abstract
OBJECTIVE The purpose of this study was to describe subsequent pregnancy outcome in women with a history of hemolysis, elevated liver enzymes, and low platelet count syndrome for which delivery occurred at < or = 28 weeks of gestation during the index pregnancy. STUDY DESIGN A descriptive report of women with previous hemolysis, elevated liver enzymes, and low platelet count syndrome who were delivered between August 1984 and July 1998 at the E.H. Crump Women's Hospital (Memphis, Tenn) and between March 1994 and July 1998 at the Central Baptist Hospital (Lexington, Ky). To have adequate time to study subsequent pregnancy outcome, only patients who were delivered >2 years before the analysis were included. Medical records of the index pregnancy and subsequent outcomes were available for review. RESULTS Adequate follow-up data were available in 69 patients; the median duration of follow-up was 5 years (range: 2-14 years). There were 76 subsequent pregnancies among 48 women, of which 62 pregnancies (82%) progressed beyond 20 weeks of gestation. Preeclampsia developed in 34 of 62 subsequent pregnancies (55%). Recurrent hemolysis, elevated liver enzymes, and low platelet count syndrome developed in 4 of these pregnancies (6%), and abruptio placentae developed in 3 of these pregnancies (5%). There were no cases of eclampsia in our population. Delivery before 37 weeks of gestation occurred in 33 of the cases (53%), and 17 of the newborn infants (27%) were small for gestational age (<10th percentile). The perinatal mortality rate was 11%. CONCLUSION Patients with a history of hemolysis, elevated liver enzymes, and low platelet count syndrome at < or = 28 weeks of gestation during the index pregnancy are at increased risk for obstetric complications in subsequent pregnancies. Overall, however, the rate of recurrent hemolysis, elevated liver enzymes, and low platelet count syndrome is only 6%.

Abstract
OBJECTIVE HELLP syndrome is defined as a subset of preeclampsia involving a combination of hemolysis, low platelets affecting the circulatory system, and elevated liver enzymes, reflecting liver cell destruction. Our objective was to assess the correlation between the platelet count changes and liver cell destruction as indicated by aspartate aminotransferase (AST) levels. METHOD We reviewed the records of 15 preeclamptic patients who developed HELLP syndrome as defined by 1) hemolysis, 2) elevated liver enzymes with an AST greater than 70 U/L (>2 SD above mean), and 3) low platelets (<100x10(9)/L). In these patients, both platelet counts and AST were assessed every 4-6 hr before and after delivery until recovery. At least eight laboratory assessments were done on each patient and were available for review. In each patient, the correlation between platelet count and AST levels was done using the Spearman rank order correlation coefficient. RESULTS A negative correlation was found between platelet count and AST levels. A correlation coefficient of greater than 0.8 occurred in 53% of cases. The correlation coefficient ranged from 0.1 to 0.93. In all cases, improvement of liver cell dysfunction occurred within 4 hr of recovery of platelet count. At 72 hr postpartum, 73% of the platelet counts had not recovered to >150x10(9)/L, and 66% of patients with abnormally elevated AST levels had not returned to <35 U/L. CONCLUSIONS Liver dysfunction and platelet count are poorly correlated in individual cases. This lack of correlation is evident both during decline and recovery of the platelet counts. Changes in platelet count cannot be used as a proxy for liver dysfunction in severe preeclampsia with HELLP syndrome.

Abstract
OBJECTIVES To compare the efficacy of dexamethasone and betamethasone to ameliorate the course of postpartum hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome. METHODS A prospective, mixed randomized/non-randomized clinical investigation of patients with postpartum HELLP syndrome. Treatment with either dexamethasone or betamethasone was continued until there was evidence of disease recovery. RESULTS Baseline characteristics of both the dexamethasone (n=18) and betamethasone (n=18) groups were similar. Although the time to discharge from the obstetrical recovery room was not statistically significant between groups, reduction in mean arterial blood pressure was more pronounced in the dexamethasone group as compared with the betamethasone group (-15.3+/-1.4 mmHg vs. -7.5+/-1.4 mmHg, respectively, P<0.01). Patients in the dexamethasone group required less antihypertensive treatment than the betamethasone group (6% vs. 50%, P=0.01) and also had a decreased need for readmission to the obstetrical recovery room (0% vs. 22%, P=0.03). CONCLUSION This investigation supports the use of dexamethasone as the superior glucocorticoid to use for patients with postpartum HELLP syndrome.

Abstract
CONTEXT HELLP syndrome is a severe complication of pregnancy characterized by hemolysis, elevated liver enzymes and low platelet count. Some pregnant women develop just one or two of the characteristics of this syndrome, which is termed Partial HELLP Syndrome (PHS). OBJECTIVE The objective of this study was to evaluate the repercussions on maternal and perinatal outcomes among women that developed PHS and to compare these women with those whose gestational hypertension or preeclampsia did not show alterations for HELLP syndrome in laboratory tests. DESIGN Observational, retrospective and analytical study. SETTING Maternity Department of Hospital das Cl nicas, Faculdade de Medicina de Botucatu, Universidade Estadual Paulista, Botucatu, S o Paulo, Brazil. SAMPLE Pregnant or post-delivery women who had a blood pressure elevation that was first detected after mid-pregnancy, with or without proteinuria, between January 1990 and December 1995. MAIN MEASUREMENTS Analysis was made of maternal age, race, parity, hypertension classification, gestational age at the PHS diagnosis, alterations in laboratory tests for HELLP syndrome, time elapsed to discharge from hospital, maternal complications, mode of delivery, incidence of preterm birth, intrauterine growth restriction, stillborn and neonatal death. RESULTS Three hundred and eighteen women were selected; forty-one women (12.9%) had PHS and 277 of them (87.1%) did not develop any of the alterations of the HELLP syndrome diagnosis. Preeclampsia was a more frequent type of hypertension in the PHS group than in the hypertension group. None of the women with isolated chronic hypertension developed PHS. The rate of cesarean delivery, eclampsia, and preterm delivery was significantly greater in the PHS group than in the hypertension group. CONCLUSION We observed that aggressive procedures had been adopted for patients with PHS. These resulted in immediate interruption of pregnancy, with elevated cesarean rates and preterm delivery. Such decisions need to be reviewed, in order to reduce the cesarean rate and the incidence of preterm delivery.

Abstract
OBJECTIVE This study was undertaken to determine whether dexamethasone or betamethasone is superior for the antepartum treatment of HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome. STUDY DESIGN This prospective, randomized, clinical investigation compared intravenously administered dexamethasone and intramuscularly administered betamethasone in the treatment of gravid women with HELLP syndrome. Efficacy end points included laboratory values (platelet count, lactate dehydrogenase activity, aspartate aminotransferase activity) and clinical parameters (mean arterial pressure, urinary output). RESULTS Forty patients were enrolled in the study, 19 in the dexamethasone arm and 21 in the betamethasone arm. The adjusted time-averaged changes from baseline were significant for aspartate aminotransferase activity (dexamethasone, -20.4 +/- 9.6 U/L; betamethasone, 9.9 +/- 8.9 U/L; P =.029), mean arterial pressure (dexamethasone, -15.6 +/- 1.4 mm Hg; betamethasone, -8.1 +/- 1.4 mm Hg; P <.001), and urinary output (dexamethasone, 12.9 +/- 8.6 mL/h; betamethasone, -11.9 +/- 8.2 mL/h; P =.043). CONCLUSION Intravenously administered dexamethasone appears to be more effective than intramuscularly administered betamethasone for the antepartum treatment of mothers with HELLP syndrome.

Abstract
HELLP syndrome is a serious, life-threatening form of pre-eclampsia with a typical laboratory triad. The incidence of the disease is reported as being 0.17-0.85% of all live births. There has been, to date, neither reliable early recognition nor effective prevention of HELLP syndrome. As a result of endothelial dysfunction, activation of intravascular coagulation occurs with fibrin deposition in the capillaries and consecutive microcirculation disorders. The disease manifests itself on average between 32-34 weeks' gestation. HELLP syndrome will occur postpartum in up to 30% of the cases. The clinical cardinal symptom of the disease is right upper quadrant pain or epigastric pain accompanied with nausea, vomiting and malaise. In 20% of the cases with HELLP syndrome there is no hypertension and 5-15% of the pregnant patients present a low level of proteinuria or none at all. The early recognition of hemolysis is most sensitively managed by the determination of the serum haptoglobin. The increase of the aspartate transaminase (AST) and the alanine transaminase (ALT) often precedes a decrease in platelets. The course of HELLP syndrome is incalculable. It is universally agreed that a pregnancy from 32-34 weeks should be immediately delivered. Before 32-34 weeks, expectant management is generally possible in a perinatal center. The frequency for a repeated hypertensive disease in pregnancy ranges from 27% to 48%.

Abstract
OBJECTIVE The aim of the study was to describe the clinical progress and maternal outcome of the (H)ELLP syndrome following temporizing management. METHODS All women (n = 127) admitted in the Academic Medical Center in Amsterdam between 1984 and 1996 with (H)ELLP syndrome and a live fetus in utero were included. The patients were treated by temporizing management, including the use of antihypertensives and magnesium sulfate. The predominant indication for terminating pregnancy was fetal distress or fetal death, and not maternal condition. MAIN OUTCOME MEASURES Maternal mortality and morbidity. RESULTS All serious maternal complications occurred at the onset of the syndrome. Two mothers with HELLP syndrome died following a cerebral hemorrhage. The remaining patients recovered completely. Serious maternal morbidity occurred more often in cases of HELLP than in cases of ELLP syndrome. Seventy-nine (62%) women were not delivered after 3 days and 65 (51%) after 7 days. CONCLUSIONS Severe complications only occurred at the onset of (H)ELLP syndrome. It is unlikely that a more aggressive approach would have reduced maternal mortality or morbidity.

Abstract
OBJECTIVE The purpose of this study was to determine the effect of corticosteroids on platelet counts and liver functions in women with pregnancies complicated by the HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome. STUDY DESIGN The study group consisted of 93 patients between 24 and 34 weeks' gestation diagnosed with HELLP syndrome. All were given intramuscular injections of either betamethasone or dexamethasone. The 3 most common regimens used were 12 mg of intramuscular betamethasone administered twice 12 hours apart, 12 mg of intramuscular betamethasone administered twice 24 hours apart, and 6 mg of intramuscular dexamethasone administered 4 times 6 hours apart. Precorticosteroid and postcorticosteroid platelet counts and liver function test results were compared. The differences in improvement in hematologic abnormalities among the 3 corticosteroid regimens were also analyzed. RESULTS The hematologic abnormalities seen in the 93 patients with HELLP syndrome improved after the administration of corticosteroids. The platelet count increased by 23.3 x 10(3)/microL (P <.001). A statistically significant decrease was seen in liver enzyme levels. The alanine aminotransferase decreased by 31.6 IU/L, the aspartate aminotransferase decreased by 52.1 IU/L, and the alkaline phosphatase decreased by 7.6 IU/L. Of the 3 regimens used, 2 doses of 12 mg of intramuscular betamethasone given every 12 hours improved the liver function to the greatest degree. CONCLUSIONS This study demonstrates that corticosteroids produce a significant improvement in the hematologic abnormalities associated with HELLP syndrome. Two doses of betamethasone given 12 hours apart was the most effective corticosteroid regimen.

Abstract
HELLP syndrome is associated with a high rate of maternal and perinatal morbidity and mortality, and often leads to immediate fetal extraction. However, this condition may occur very early in pregnancy and conservative approaches have been recently proposed. The limits of this approach are discussed with two cases of conservative management of HELLP syndrome complicated by abruptio placentae.

Abstract
OBJECTIVE To evaluate the effect of corticosteroid treatment on the postpartum recovery of parturients with HELLP syndrome. METHOD Thirty cases with HELLP syndrome were randomly assigned to a study or a control group, each including 15 patients. A total dose of 30 mg intravenous dexamethasone was given to the study group during the 36 h following the childbirth, while the control group did not receive any steroid medication. Arterial blood pressure, urine output, hematocrit ratio, platelet count, serum alanine and aspartate aminotransferases and uric acid levels were monitored during the first 48 h postpartum. The data were analyzed by unpaired t-test, chi2 or Fisher's exact tests. RESULT Before the treatment, no significant difference was observed between the two groups. The study group showed statistically significant improvement in mean arterial blood pressure, mean serum aspartate aminotransferase level, mean urine volume per hour and mean platelet count (P < 0.05). Length of hospitalization was also shorter in the study group (P < 0.01). CONCLUSION Early postpartum high-dose corticosteroid treatment accelerates the recovery and shortens the hospitalization of the parturients with HELLP syndrome.

Abstract
Hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome is a form of severe preeclampsia that threatens the gravida and her fetus. In this report, the diagnostic criteria and maternal and fetal risks of HELLP are defined. Prompt recognition and treatment in tertiary centers is emphasized, because the prognosis can be adversely affected by delayed or less than optimal diagnosis and treatment. Management guidelines are offered for treating this disorder. The potential roles of corticosteroids, plasmapheresis, and expectant management are critically evaluated. Subsequent pregnancy outcome, contraception, and preventative strategies are considered.

Abstract
Most diseases of the hepatic and biliary systems affect both women and men. There are several disorders, however, that affect women differently than they affect men. Gallstones, primary biliary cirrhosis (PBC), and autoimmune liver disease occur more often in women. The impact of alcohol on the liver is worse in women. Chronic liver disease from any cause can affect fertility. In addition, oral contraceptive use and pregnancy can have specific effects on the liver.

Abstract
OBJECTIVE To assess the relationship between the subtypes of hypertension in pregnancy and subsequent neonatal haematology. METHODOLOGY Retrospective review of the haematology of newborns of hypertensive mothers at a tertiary neonatal unit. RESULTS Over a 2 year period, 249 infants had full blood examinations. Nineteen (7.6%) were neutropenic and 35 (14.1%) thrombocytopenic, including 11 (4.4%) who were both neutropenic and thrombocytopenic. Neutropenia occurred only in infants whose mothers had severe pre-eclampsia and eclampsia or pre-eclampsia with pre-existing hypertension, whereas thrombocytopenia complicated all maternal hypertension subtypes. Two (10%) of the neutropenic infants developed nosocomial infection while seven (20%) of the thrombocytopenic infants bled. Thirteen (68%) of the neutropenic infants compared with 15 (43%) of the thrombocytopenic infants developed their haematological abnormality within 24 h of birth. All but two infants developed the haematological abnormality by the 5th day of life. CONCLUSION Although haematological abnormalities in infants born to hypertensive mothers are uncommon, serious neonatal complications can occur and therefore early haematological screening of these infants is recommended.

Abstract
OBJECTIVE To test the null hypothesis that the course and outcome of pregnancy in patients with severe pre-eclampsia receiving temporising haemodynamic treatment does not depend on the presence or absence of the syndrome of haemolysis, elevated liver enzymes, and a low platelet count (HELLP). DESIGN A case-controlled study. SETTING High risk obstetric unit, University Hospital Rotterdam-Dijkzigt, Rotterdam. SUBJECTS One hundred and twenty-eight consecutive pre-eclamptic patients with HELLP, gestational age less than 34 weeks, matched for maternal and gestational age with 128 pre-eclamptic patients without HELLP. INTERVENTION Both groups were treated with volume expansion and pharmacologic vasodilatation under invasive haemodynamic monitoring with the aim of prolonging gestation and enhancing fetal maturity. MAIN OUTCOME MEASURES Maternal and perinatal outcome in patients with and without HELLP. RESULTS Except for variables pertaining to HELLP, clinical and laboratory data and median prolongation of pregnancy did not differ between both groups. Complete reversal of HELLP occurred in 43% of patients. Perinatal mortality was 14.1% in HELLP patients and 14.8% in patients without HELLP. No maternal complications occurred. CONCLUSION We cannot reject the null hypothesis. Our data do not support a general recommendation of prompt termination of pregnancy in HELLP. Temporising treatment may improve fetal and neonatal as well as maternal outcome.
