Abstract
Thrombotic microangiopathies (TMAs) comprise a distinct group of diseases with different manifestations that can occur in both pediatric and adult patients. They can be hereditary or acquired, with subtle onset or a rapidly progressive course, and they are particularly known for their morbidity and mortality. Pregnancy is a high-risk time for the development of several types of thrombotic microangiopathies. The three major syndromes are hemolysis, elevated liver function tests, and low platelets (HELLP); hemolytic uremic syndrome (HUS); and thrombotic thrombocytopenic purpura (TTP). Because of their rarity, clinical information and therapeutic results related to these conditions are often obtained from case reports, small series, registries, and reviews. The collection of individual observations, the evolution of diagnostic laboratories that have identified autoimmune and/or genetic abnormalities using von Willebrand factor post-secretion processing or genetic-functional alterations in the regulation of alternative complement pathways in some of these TMAs, and, most importantly, the introduction of advanced treatments, have enabled the preservation of affected organs and improved survival rates. Although TMAs may show different etiopathogenesis routes, they all show the presence of pathological lesions, which are characterized by endothelial damage and the formation of thrombi rich in platelets at the microvascular level, as a common denominator, and thrombotic damage to microcirculation pathways induces "mechanical" (microangiopathic) hemolytic anemia, the consumption of platelets, and ischemic organ damage. In this review, we highlight the current knowledge about the diagnosis and management of these complications during pregnancy.

Abstract
OBJECTIVE Substantial controversy exists regarding anesthetic management for patients with preeclampsia or hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome. Experts, researchers, clinicians, and residents in Turkey were surveyed about their practices. MATERIAL AND METHODS Questionnaires were distributed to attendees at a national conference, and they were filled out immediately. Anonymous 10-item paper surveys were administered to both residents and non-residents. Descriptive statistics were used in the analysis. Agreement among ≥75% of the respondents was considered a majority opinion. Surveys with missing responses were used to analyze the non-response bias. The Chi-square test was used for comparisons. A historical cohort of obstetricians-gynecologists was used for comparison with anesthesiologists. RESULTS Of 339 surveys distributed, 288 were returned (84.9% response rate). Among the returned surveys, the completion rate was 96.1%. The job experience in years among clinicians and residents was 9±5 and 3±1, respectively. General anesthesia was still significantly preferred by 36.1% among patients with preeclampsia with platelet counts of ≥100,000/μL. Compared to obstetricians-gynecologists, anesthesiologists more often preferred general anesthesia. With platelet counts of <50,000/μL or eclampsia, most respondents preferred general anesthesia 94.4% for very low platelets and 89.5% for eclampsia. CONCLUSION A preferential trend toward general anesthesia for patients with preeclampsia or HELLP syndrome exists among anesthesiologists in Turkey, particularly for patients with severe thrombocytopenia and/or eclampsia. There exists a need for well-designed and well-executed prospective clinical trials to provide evidence for the best consensus practice.

Abstract
The aim of this study was to identify the factors which can affect the efficacy of corticosteroid (CORT) therapy in the management of hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. Research articles reporting the efficacy of CORT therapy to HELLP syndrome patients were searched in several electronic databases including EMBASE, Google Scholar, Ovid SP, PubMed, and Web of Science. Study selection was based on predefined eligibility criteria. Efficacy was defined by the changes from baseline in HELLP syndrome indicators after CORT therapy. Meta-analyses were carried out with Stata software. Data of 778 CORT-treated HELLP syndrome patients recruited in 22 studies were used in the analyses. Corticosteroid treatment to HELLP syndrome patients was associated with significant changes from baseline in platelet count; serum levels of aspartate aminotransaminase, alanine transaminase, and lactic dehydrogenase (LDH); mean blood pressure; and urinary output. Lower baseline platelet count predicted higher change in platelet count after CORT therapy. Lower baseline platelet count and lower baseline urinary output predicted greater changes in LDH levels after CORT therapy. There was also an inverse relationship between the change from baseline in LDH levels and intensive care duration. Higher CORT doses were associated with greater declines in the aspartate aminotransaminase, alanine transaminase, and LDH levels. Incidence of cesarean delivery was inversely associated with the gestation age. The percentage of nulliparous women had a positive association with the intensive care stay duration. High-dose CORT therapy to HELLP syndrome patients provides benefits in improving disease markers and reducing intensive care duration, especially in cases such as mothers with much lower baseline platelet count and LDH levels.

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 platelet count (HELLP) syndrome is a severe condition of pregnancy that is associated with significant morbidity and mortality. Corticoteroid (CORT) therapy is common in the management of HELLP syndrome. This study evaluates the efficacy of CORT therapy to patients with HELLP Syndrome. Material/Methods A literature search was carried out in multiple electronic databases. Meta-analyses of means difference and odds ratio were carried under the random-effects model. Results Fifteen studies (675 CORT treated and 787 control HELLP patients) were included. CORT treatment significantly improved platelet count (mean difference between CORT treated and controls in changes from baseline, MD: 38.08 [15.71, 60.45]×109; p=0.0009), lactic dehydrogenase (LDH) levels (MD: −440 [−760, −120] IU/L; p=0.007), and alanine aminotransferase (ALT) levels (MD: −143.34 [−278.69, −7.99] IU/L; p=0.04) but the decrease in aspartate aminotransferase (AST) levels was not statistically significant (MD: −48.50 [−114.32, 17.32] IU/L; p=0.15). Corticosteroid treatment was also associated with significantly less blood transfusion rate (odds ratio, OR: 0.42 [0.24, 0.76]; p=0.004) and hospital/ICU stay (MD: −1.79 [−3.54, −0.05] days; p=0.04). Maternal mortality (OR: 1.27 [0.45, 3.60]; p=0.65), birth weight (MD: 0.09 [−0.11, 0.28]; p=0.38) and the prevalence of morbid conditions (OR: 0.79 [0.58, 1.08]; p=0.14) did not differ significantly between both groups. Conclusions Corticosteroid administration to HELLP patients improves platelet count, and the serum levels of LDH and ALT, and reduces hospital/ICU stay and blood transfusion rate, but is not significantly associated with better maternal mortality and overall morbidity.

Abstract
OBJECTIVE The aim of the study was to find out the role of Serum lactate dehydrogenase in prediction of adverse outcomes of PE & E i.e., severity of disease and occurrence of complications. MATERIALS AND METHODS This study was conducted in the Department of Obstetrics and Gynaecology, MGM Medical College, Indore. A total of 200 women were studied; they were divided into control (n = 100), severe pre-eclampsia (n = 32), eclampsia (n = 68). Demographic and hematological parameters were studied including LDH levels. RESULTS The incidence of severe pre-eclampsia-1.2 % & Eclampsia 2.7 %, PE & E patients were significantly younger, with low gravidity and parity. They had significantly increased systolic and diastolic pressure, liver enzymes, uric acid, urine albumin, and LDH levels. Serum urea and creatinine were normal in majority of cases. The symptoms and complications of PE along with perinatal mortality were increased significantly in patients with LDH >800 IU/l compared with those who had lower levels. Complications like Retinopathy, ARF, Abruptio, DIC, CVA, MODS, Shock were also associated with high level of serum LDH >800 IU/L. Low birth weight of babies was also associated with high level of serum LDH levels in PE & E patients. The incidence of poor perinatal outcome was higher in PE & E patients with high serum LDH level (>600 IU/L). CONCLUSION LDH is the earliest marker seen in blood during hypoxia and oxidative stress. It is a useful biochemical marker that reflects the severity of and the occurrence of complications of PE & E; these are preventable if identified at an earlier stage and adequately managed at a higher center. Test is easily available, so screening of all cases of PE & E with LDH levels must be made mandatory.

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
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
OBJECTIVES To evaluate the effect of the time interval between administering antenatal steroids needed to accelerate fetal lung maturity and indicated delivery in preterm pregnancies complicated by severe hypertension, as determined by maternal and perinatal outcomes. METHODS The Nova Scotia Atlee Perinatal Database was used to identify a population-based cohort of women with severe hypertension who delivered an infant between 1989 and 2002. Women were included if they received antenatal steroids and required delivery between 26 and 34 weeks gestation. Multivariate logistic regression analyses were conducted to evaluate the effect of time interval on maternal and perinatal mortality, maternal hemorrhagic and hypertension-associated morbidity, and perinatal respiratory, infectious, and prematurity-associated morbidity, while controlling for confounding variables. RESULTS 172 pregnancies satisfied inclusion and exclusion criteria. Betamethasone was the most commonly used corticosteroid to accelerate fetal lung maturity (95%). Among infants delivered at 26 to 34 weeks, adjusted analyses showed a reduction in risk of depression at birth (RR, 0.54; 95% CI, 0.24 to 0.97) and need for surfactant (RR, 0.50; 95% CI, 0.25 to 0.95) when the time interval from steroid administration to delivery was >48 hours compared with <or= 48 hours. Adjusted analyses in a subgroup of women with cesarean delivery (81% of deliveries) demonstrated no differences in rates maternal or neonatal morbidity. CONCLUSIONS The rates of most adverse maternal and neonatal outcomes in preterm pregnancies with severe hypertension delivered at 26 to 34 weeks are not affected by timing from steroid administration to delivery. These data support the decision for delivery based mainly on obstetrical indications.

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
AIM The present study aims to investigate the effects of betamethasone treatment on clinical outcome and laboratory data of pregnant women diagnosed with HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome. METHODS A prospective, randomized and placebo-controlled clinical trial was undertaken in a total of 60 pregnant women with HELLP syndrome who were treated at the perinatology department of the study center between January 2005 and February 2008. Betamethasone treatment (intramuscular injection of 12 mg in every 24 h) was given to 30 subjects while remaining 30 subjects received placebo. The treatment and control groups were compared in the aspects of clinical outcome and laboratory data. RESULTS The alterations in platelet counts, alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase levels of women treated with betamethasone were statistically similar to those of the placebo group. Although there was a significant decrease in diastolic blood pressure values of control group (P = 0.04), alterations in systolic blood pressure values were statistically indifferent in both study groups. Hematological and metabolic complications occurred significantly less in women treated with betamethasone (P < 0.05). Interestingly, the percentage of women who received platelet transfusion was significantly higher in the control group (P < 0.005). No case of maternal mortality occurred. CONCLUSIONS The betamethasone treatment has ended up with insignificant alterations in clinical outcomes and laboratory data of women with HELLP syndrome except beneficial effects on metabolic complications and need for platelet transfusion. Further investigation is required to assess the efficiency of betamethasone in management of HELLP syndrome.

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
The authors previously reported a case of decreased pseudocholinesterase activity in a patient with HELLP syndrome. It was assumed that the reduced pseudocholinesterase activity in HELLP syndrome is associated with impaired liver function. The present study assesses the prevalence of low pseudocholinesterase in patients with HELLP syndrome. Serum pseudocholinesterase activity was determined with spectrophotometer in 15 patients with HELLP syndrome. Two control groups matched for gestational age were recruited: 15 healthy women with uncomplicated pregnancy and 15 women with severe preeclampsia without HELLP. The prevalence of reduced pseudocholinesterase activity lower than normal limit was 60.0% (9/15) in patients with HELLP syndrome, 33.3% (5/15) in patients with severe preeclampsia, and 6.6% (1/15) in women with normal pregnancy, respectively (P =.009). The pseudocholinesterase activity was found to correlate with serum alanine aminotransferase levels (r = 0.417, P = .006) and with serum aspartate aminotransferase levels (r = 0.462, P = .002). Considering the increased prevalence of reduced pseudocholinesterase activity in patients with HELLP syndrome, the authors suggest that whenever general anesthesia is applied in these patients, the anesthesiologist should be aware that the patient may show slow metabolic degradation of choline-ester drugs.

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
UNLABELLED Preeclampsia/eclampsia has been recognized for centuries and continues to plague both the patient and the obstetrician. A severe variant, the syndrome of hemolysis, elevated liver enzymes, and low platelets (HELLP), has been recognized for 50 years. Although much new data has been elucidated about the condition, only several observations have withstood the test of time. These are the uniqueness of the disease to humans, the progressive nature of the disease, and the fact that delivery is the sole therapy. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to outline the history of HELLP syndrome and describe the pathophysiology of HELLP syndrome, to summarize the clinical presentation and differential diagnosis of HELLP syndrome, and to list the various management options.

Abstract
OBJECTIVE We reviewed the impact of intravenous high-dose corticosteroid administration for preterm hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome on vaginal delivery rate and degree of clinically significant thrombocytopenia. METHODS Retrospective analysis of 1991-2000 HELLP syndrome (platelets < 100,000/uL, lactate dehydrogenase > 600 IU/L, aspartate aminotransferase and/or alanine aminotransferase > 70 IU/L) data focusing on labor inductions for gestations of less than 34 weeks and increase in platelet count sufficient to permit regional anesthetic techniques. RESULTS Antepartum high-dose corticosteroid use increased from 32% (1991-1995) to 67% (1996-2000) for 350 patients studied (n = 199, < 34 weeks; n = 151, > 34 weeks). Corresponding vaginal delivery rates were 32% for gestations of less than 30 weeks, 61% at 30-31 weeks, and 62% at 32-33 weeks. Similarly, 27% of patients with a platelet count of less than 75,000/uL and 52% with a platelet count of less than 100,000/uL who received high-dose corticosteroids during the study interval subsequently achieved a 100,000/uL threshold in time to perform regional anesthesia for delivery. CONCLUSION Administration of intravenous high-dose corticosteroids for preterm HELLP syndrome increases probability of successful labor induction and candidacy for regional anesthesia.

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
Hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome has been recognized as a complication of preeclampsia-eclampsia for decades. Recognition of this syndrome in women with preeclampsia is increasing because of the frequency of blood test results that reveal unexpected thrombocytopenia or elevated liver enzymes. The diagnosis of HELLP syndrome requires the presence of hemolysis based on examination of the peripheral smear, elevated indirect bilirubin levels, or low serum haptoglobin levels in association with significant elevation in liver enzymes and a platelet count below 100,000/mm(3) after ruling out other causes of hemolysis and thrombocytopenia. The presence of this syndrome is associated with increased risk of adverse outcome for both mother and fetus. During the past 15 years, several retrospective and observational studies and a few randomized trials have been published in an attempt to refine the diagnostic criteria, to identify risk factors for adverse pregnancy outcome, and to treat women with this syndrome. Despite the voluminous literature, the diagnosis and management of this syndrome remain controversial. Recent studies suggest that some women with partial HELLP syndrome may be treated with expectant management or corticosteroid therapy. This review will emphasize the controversies surrounding the diagnosis and management of this syndrome. Recommendation for diagnosis, management, and counseling of these women is also provided based on results of recent studies and my own clinical experience.

Abstract
OBJECTIVE We compared maternal outcomes for patients with HELLP (hemolysis, elevated liver enzymes, and low platelet count) syndrome treated with or without high-dose corticosteroids to ameliorate maternal disease. STUDY DESIGN An analysis of data for patients with HELLP syndrome (platelets, <or=100,000/microL; lactate dehydrogenase level, >or=600 IU/L; aspartate aminotransferase and/or alanine aminotransferase level, >or=70 IU/L) who were treated during the 7-year epochs before and after the clinical trials in 1992 and 1993 demonstrated maternal benefit with high-dose dexamethasone. RESULTS Corticosteroid use increased from 16% (39/246 patients) for fetal indication from 1985 to 1991 to 90% (205/228 patients) for maternal-fetal indications from 1994 to 2000. Significantly reduced composite maternal disease from 1994 to 2000 was evidenced by improvements in laboratory parameters, disease progression to class 1 HELLP syndrome, the degree of hypertension, the need for antihypertensive therapy, the use of transfusion, and the presence of maternal morbidity (P<.05). Indices of postpartum recovery also were shortened significantly (P<.001). CONCLUSION Routine early initiation of high-dose intravenous corticosteroids for patients with HELLP syndrome significantly lessened maternal disease, reduced maternal morbidity, and expedited recovery.
