Abstract
Severe obstetric hemorrhage is a leading cause of maternal mortality and morbidity worldwide. Major hemorrhage in the antepartum period presents potential risks for both the mother and the fetus. Similarly, postpartum hemorrhage (PPH) accounts for up to a quarter of maternal deaths worldwide. Potential causes of severe antepartum hemorrhage that radiologists should be familiar with include placental abruption, placenta previa, placenta accreta spectrum disorders, and vasa previa. Common causes of PPH that the authors discuss include uterine atony, puerperal genital hematomas, uterine rupture and dehiscence, retained products of conception, and vascular anomalies. Bleeding complications unique to or most frequently encountered after cesarean delivery are also enumerated, including entities such as bladder flap hematomas, rectus sheath and subfascial hemorrhage, and infectious complications of endometritis and uterine dehiscence. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

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
Examination of red blood cell (RBC) morphology in peripheral blood smears can help diagnose hematologic diseases, even in resource-limited settings, but this analysis remains subjective and semiquantitative with low throughput. Prior attempts to develop automated tools have been hampered by their poor reproducibility and limited clinical validation. Here, we present a novel, open-source machine-learning approach (denoted as RBC-diff) to quantify abnormal RBCs in peripheral smear images and generate an RBC morphology differential. RBC-diff cell counts showed high accuracy for single-cell classification (mean AUC, 0.93) and quantitation across smears (mean R2, 0.76 compared with experts, interexperts R2, 0.75). RBC-diff counts were concordant with the clinical morphology grading for 300 000+ images and recovered the expected pathophysiologic signals in diverse clinical cohorts. Criteria using RBC-diff counts distinguished thrombotic thrombocytopenic purpura and hemolytic uremic syndrome from other thrombotic microangiopathies, providing greater specificity than clinical morphology grading (72% vs 41%; P < .001) while maintaining high sensitivity (94% to 100%). Elevated RBC-diff schistocyte counts were associated with increased 6-month all-cause mortality in a cohort of 58 950 inpatients (9.5% mortality for schist. >1%, vs 4.7% for schist; <0.5%; P < .001) after controlling for comorbidities, demographics, clinical morphology grading, and blood count indices. RBC-diff also enabled the estimation of single-cell volume-morphology distributions, providing insight into the influence of morphology on routine blood count measures. Our codebase and expert-annotated images are included here to spur further advancement. These results illustrate that computer vision can enable rapid and accurate quantitation of RBC morphology, which may provide value in both clinical and research contexts.

Abstract
BACKGROUND Immediate delivery is an established concept for preventing life-threatening complications in mothers with HELLP syndrome; however, it is associated with preterm births. METHODS Cases of HELLP syndrome diagnosed at the university hospitals of Halle and Magdeburg (Germany) were analyzed retrospectively. Each patient of the treatment group was administered 64 mg of methylprednisolone (MP) intravenously for 10 days, with the dosage being reduced by 50% every other day in patients from Halle (n = 65). Almost immediate delivery was performed in the control groups (n = 45, Halle; n = 28, Magdeburg). RESULTS Pregnancies in the treatment group were prolonged by 4 days (median 1-55 days). The platelet counts increased from 76,060 ± 22,900/μL to 117,430 ± 39,065/μL in the MP group compared with an increase from 66,500 ± 25,852/μL to 83,430 ± 34,608/μL in control group 1 and from 78,890 ± 19,100/μL to 131,080 ± 50,900/µL in control group 2 (p < 0.001). Severe neonatal complications were significantly reduced in the treatment group (p < 0.05): sepsis, 9.25% vs. 24%; ventilation, 44.6% vs. 46.5%; and infant death, 1.6% vs. 8.6%. CONCLUSIONS In a selected collective of patients with HELLP syndrome, prolongation of pregnancy using MP treatment improved maternal and neonatal outcomes.

Abstract
Purpose To investigate the clinical classification, pregnancy outcomes and risk factors of pregnant women with severe preeclampsia (SPE) complicated with HELLP (hemolysis, elevated liver enzymes, and low platelets) syndrome. Methods The clinical data of 50 pregnant women diagnosed with SPE complicated with HELLP syndrome in our hospital from January 2014 to January 2021 were retrospectively analyzed, and they were selected as the observation group. An additional 50 maternities diagnosed with preeclampsia (PE) during the same period were selected as the control group. The clinical classification and pregnancy outcomes of pregnant women in the observation group were recorded. The age and gestational age of onset of pregnancy were recorded and compared between the two groups. Univariate analysis and multivariate logistic regression model were used to analyze the risk factors for its occurrence. Results Among the 50 maternities in the observation group, there were 10 cases of type I, accounting for 20.00%; 35 cases of type II, accounting for 70.00%; 5 cases of type III, accounting for 10.00%. Partial 33 cases, the composition ratio of 66.00%; complete 17 cases, the composition ratio of 34.00%. Among the fetuses of 50 maternities in the observation group, 35 were premature, accounting for 70.00%; 13 had fetal growth restriction, accounting for 26.00%; and 2 died during perinatal period, accounting for 4.00%. Among the 50 maternities in the observation group, 48 cases were cesarean section, the composition ratio was 96.00%; 2 cases were induced labor, the composition ratio was 4.00%; there was no natural birth, the composition ratio was 0.00%. Univariate analysis showed that age, gestational age at onset, gestational age at termination of pregnancy, HGB, LDH, ALT, AST, TBIL, PLT, PT, and FIB were all associated with the occurrence of SPE complicated with HELLP syndrome (P < 0.05). Multivariate logistic analysis showed that gestational age at onset, gestational age at termination of pregnancy, HGB, LDH, ALT, AST, TBIL, PLT, and FIB were independent risk factors for SPE complicated with HELLP syndrome (P < 0.05). Conclusion SPE complicated with HELLP syndrome has significantly increased adverse pregnancy outcomes. Understanding its clinical classification is of great significance for the preventive application of platelet transfusion therapy and the selection of transfusion timing. Gestational age at onset and gestational age at termination of pregnancy are independent risk factors for its occurrence. Fully understanding the high-risk factors of HELLP syndrome, taking preventive measures in time, and carrying out targeted nursing can effectively improve the prognosis of pregnant women and reduce the risk of HELLP syndrome.

Preeclampsia and eclampsia: the conceptual evolution of a syndrome. Am J Obstet Gynecol 2022; 226:S786-S803.

Abstract
Preeclampsia, one of the most enigmatic complications of pregnancy, is considered a pregnancy-specific disorder caused by the placenta and cured only by delivery. This article traces the condition from its origins-once thought to be a disease of the central nervous system, recognized by the occurrence of seizures (ie, eclampsia)-to the present time when preeclampsia is conceptualized primarily as a vascular disorder. We review the epidemiologic data that led to the recommendation to use diastolic hypertension and proteinuria as diagnostic criteria, as their combined presence was associated with an increased risk of fetal death and the birth of small-for-gestational-age neonates. However, preeclampsia is a multisystemic disorder with protean manifestations, and the condition can be present even in the absence of hypertension and proteinuria. Toxins gaining access to the maternal circulation have been proposed to mediate the clinical manifestations-hence, the term "toxemia of pregnancy," which was used for several decades. The search for putative toxins has challenged investigators for more than a century, and a growing body of evidence suggests that products of an ischemic or a stressed placenta are responsible for the vascular changes that characterize this syndrome. The discovery that the placenta can produce antiangiogenic factors, which regulate endothelial cell function and induce intravascular inflammation, has been a major step forward in the understanding of preeclampsia. We view the release of antiangiogenic factors by the placenta as an adaptive response to improve uterine perfusion by modulating endothelial function and maternal cardiovascular performance. However, this homeostatic response can become maladaptive and lead to damage of target organs during pregnancy or the postpartum period. Early-onset preeclampsia has many features in common with atherosclerosis, whereas late-onset preeclampsia seems to result from a mismatch of fetal demands and maternal supply, that is, a metabolic crisis. Preeclampsia, as it is understood today, is essentially vascular dysfunction unmasked or caused by pregnancy. A subset of patients diagnosed with preeclampsia are at greater risk of the subsequent development of hypertension, ischemic heart disease, heart failure, vascular dementia, and end-stage renal disease. However, these adverse events may be the result of a preexisting vascular pathologic process; it is not known if the occurrence of preeclampsia increases the baseline risk. Therefore, the understanding, prediction, prevention, and treatment of preeclampsia are healthcare priorities.

Abstract
Hypertensive disorders of pregnancy can be classified as chronic hypertension (present before pregnancy), gestational hypertension (onset after 20 weeks of pregnancy), and preeclampsia (onset after 20 weeks of pregnancy, along with proteinuria and other organ dysfunction). Preeclampsia and related disorders are a major cause of maternal and fetal morbidity and mortality. Preeclampsia is believed to result from an angiogenic imbalance in the placenta circulation. Antenatal screening and early diagnosis may help improve outcomes. Severe preeclampsia is characterized by SBP ≥160 mm Hg, or DBP ≥110 mm Hg, thrombocytopenia (platelet count <100 × 109/L), abnormal liver function, serum creatinine >1.1 mg/dL, or a doubling of the serum creatinine concentration in the absence of other renal diseases, disseminated intravascular coagulation, pulmonary edema, new-onset headache, or visual disturbances. Severe preeclampsia or eclampsia (preeclampsia with seizures) needs ICU management and is the main cause of morbidity and mortality. Severe hypertension can also result in life-threatening intracranial hemorrhage. Blood pressure control, seizure prevention, and appropriate timing of delivery are the cornerstones of the management of preeclampsia. Besides intravenous antihypertensive drugs, intravenous magnesium sulfate is the drug of choice to prevent or treat seizures, when preparing for urgent delivery. At present, delivery remains the most effective treatment for preeclampsia, and organ dysfunction rapidly recovers after delivery. Novel therapeutic interventions are under development to reduce complications. How to cite this article Narkhede AM, Karnad DR. Preeclampsia and Related Problems.

Abstract
AIM Hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome is an extremely advanced form of preeclampsia. Currently, there is no parameter or marker to predict this syndrome; however, it is emphasized that vascular endothelial damage and abnormal immune responses can be the possible etiologies of HELLP syndrome. It is known that human epididymis protein 4 (HE4) is a protease inhibitor and previous studies have shown that HE4 protein levels are increased in many malignancies and inflammatory conditions. Considering that metalloproteinases may also play a role in endothelial damage, which is thought to be involved in the etiopathogenesis of HELLP syndrome, we thought that HE4 protein, which is a protease inhibitor, may be associated with vascular damage. We aimed to investigate the relationship between HELLP syndrome and HE4 protein and to identify a biomarker that can be utilized in the diagnosis of HELLP syndrome. STUDY DESIGN In this study, 40 patients with HELLP syndrome and 40 healthy pregnant women with similar characteristics without HELLP syndrome were compared. RESULTS When the results were evaluated, no statistically significant difference was found between serum HE4 protein levels in patients with HELLP syndrome and patients without HELLP syndrome in this study (p: 0.29). CONCLUSION HE4 protein has no field of use in obstetrics yet. In our study, we aimed to find a new biomarker to identify patients with HELLP syndrome. However, we could not find any statistically significant difference in terms of HE4 protein levels between patients with and without HELLP syndrome. Our study is an important study as it is the first study aiming to use HE4 protein in obstetrics.

Abstract
The postpartum period, also known as the puerperium, begins immediately after delivery of the neonate and placenta and ends 6-8 weeks after delivery. The appearance of physiologic uterine changes during puerperium can overlap with that of postpartum complications, which makes imaging interpretation and diagnosis difficult. Obstetric and nonobstetric postpartum complications are a considerable source of morbidity and mortality in women of reproductive age, and the radiologist plays an important role in the assessment of these entities, which often require a multimodality imaging approach. US and contrast material-enhanced CT are the techniques of choice in the emergency department, and they can show characteristic radiologic findings that enable differentiation between normal and abnormal features to help radiologists and emergency department practitioners to reach a correct diagnosis and provide timely treatment. The spectrum of postpartum complications ranges from relatively self-limiting to life-threatening conditions that can be divided into six categories: infectious conditions (endometritis), thrombotic complications (eg, deep vein thrombosis, ovarian vein thrombophlebitis, HELLP [hemolysis, elevated liver enzymes, and low platelet count] syndrome, or cerebral sinus thrombosis), hemorrhagic conditions (eg, uterine atony, trauma of the lower portion of the genital tract, retained products of conception, uterine artery arteriovenous malformations, or uterine artery pseudoaneurysm), cesarean delivery-related complications (eg, bladder flap hematoma, subfascial hematoma, rectus sheath hematoma, abscess formation, uterine dehiscence, uterine rupture, vesicovaginal fistula, or abdominal wall endometriosis), iatrogenic conditions (eg, uterine perforation), and nonobstetric complications (eg, acute cholecystitis, acute appendicitis, uterine fibroid degeneration, renal cortical necrosis, pyelonephritis, posterior reversible encephalopathy syndrome, or pituitary gland apoplexy).

[PMID: 32435066 PMCID: PMC7234826 DOI: 10.1055/a-1091-8630] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Revised: 12/15/2019] [Accepted: 01/08/2020] [Indexed: 12/17/2022] Open
Abstract
HELLP syndrome and the less common acute fatty liver of pregnancy (AFL) are unpredictable, life-threatening complications of pregnancy. The similarities in their clinical and laboratory presentations are often challenging for the obstetrician when making a differential diagnosis. Both diseases are characterised by microvesicular steatosis of varying degrees of severity. A specific risk profile does not exist for either of the entities. Genetic defects in mitochondrial fatty acid oxidation and multiple pregnancy are considered to be common predisposing factors. The diagnosis of AFL is based on a combination of clinical symptoms and laboratory findings. The Swansea criteria have been proposed as a diagnostic tool for orientation. HELLP syndrome is a laboratory diagnosis based on the triad of haemolysis, elevated aminotransferase levels and a platelet count < 100 G/l. Generalised malaise, nausea, vomiting and abdominal pain are common symptoms of both diseases, making early diagnosis difficult. Clinical differences include a lack of polydipsia/polyuria in HELLP syndrome, while jaundice is more common and more pronounced in AFL, there is a lower incidence of hypertension and proteinuria, and patients with AFL may develop encephalopathy with rapid progression to acute liver failure. In contrast, neurological symptoms such as severe headache and visual disturbances are more prominent in patients with HELLP syndrome. In terms of laboratory findings, AFL can be differentiated from HELLP syndrome by the presence of leucocytosis, hypoglycaemia, more pronounced hyperbilirubinemia, an initial lack of haemolysis and thrombocytopenia < 100 G/l, as well as lower antithrombin levels < 65% and prolonged prothrombin times. While HELLP syndrome has a fluctuating clinical course with rapid exacerbation within hours or transient remissions, AFL rapidly progresses to acute liver failure if the infant is not delivered immediately. The only causal treatment for both diseases is immediate delivery. Expectant management between 24 + 0 and 33 + 6 weeks of gestation is recommended for HELLP syndrome, but only in cases where the mother can be stabilised and there is no evidence of foetal compromise. The maternal mortality rate for HELLP syndrome in developed countries is approximately 1%, while the rate for AFL is 1.8 – 18%. Perinatal mortality rates are 7 – 20% and 15 – 20%, respectively. While data on the long-term impact of AFL on the health of mother and child is still insufficient, HELLP syndrome is associated with an increased risk of developing cardiovascular, metabolic and neurological diseases in later life.

Liver Transplantation for Hemolysis, Elevated Liver Enzymes, and Low Platelet Count Syndrome: A Propensity-score Matched Long-term Survival of the Scientific Registry of Transplant Recipients Dataset. Transplant Proc 2019; 51:805-812.

Abstract
BACKGROUND Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a life-threatening form of pre-eclampsia/eclampsia, with liver transplantation being the life-saving option for treatment for those who develop severe hepatic complications. METHODS We retrospectively analyzed data from the Scientific Registry of Transplant Recipients (SRTR) through October 1, 1987, to December 31, 2014. Forty patients were listed for liver transplantation, with 18 patients finally receiving their transplant. These 18 patients were matched with 1:10 patients using a propensity-score matched approach. RESULTS Baseline demographics were comparable between HELLP syndrome patients who received a transplant and those who did not. The 10-year intent-to-treat survival was 63.6% for non-transplanted HELLP patients, 64.2% for transplanted HELLP patients, and 61.8% for matched patients (P = .369). Overall survival was also similar between HELLP patients and matched patients, with 10-year survival at 64.2% and 61.8% respectively (P = .985). However, death-censored graft survival was inferior in HELLP patients, with 10-year survival at 63.4% compared with 75.4% in the matched patients (P = .044). CONCLUSIONS Patients with HELLP syndrome who did not receive a transplant achieved similar intent-to-treat survival with those transplanted patients, while the death-censored graft survival of transplanted patients was inferior to matched patients. This might guide improved liver donor allocation in clinical practice.

Abstract
Background For the past decades the mean age of primiparae in Western societies is constantly increasing. At the same time, there is a growing demand for assisted reproductive technologies such as in vitro fertilization and intracytoplasmic sperm injection. Subsequently, a higher prevalence of pregnancy-associated diseases such as gestational hypertension and preeclampsia is observed. To improve pregnancy rates after in vitro fertilization/intracytoplasmic sperm injection and to reduce the risk of pregnancy-associated diseases with a cardiovascular pathophysiology, two anticoagulants are the focus of current research: low molecular weight heparin and acetylsalicylic acid (aspirin). Case presentation A 41-year-old white woman, gravida 3, para 0, received low molecular weight heparin to reduce the risk of abortion after five unsuccessful intracytoplasmic sperm injections and two miscarriages. She autonomously discontinued the medication with low molecular weight heparin at 12 weeks and 2 days of gestation and took aspirin instead until 24 weeks and 2 days of gestation as preeclampsia prophylaxis. However, the pregnancy ended with an urgent cesarean section at 27 weeks and 4 days of gestation due to a fast progressing hemolysis, elevated liver enzyme levels, and low blood platelet count syndrome, a potentially life-threatening variant of preeclampsia. Conclusion Based on the current demographic trend toward late-in-life pregnancy it is mandatory to establish clear guidelines concerning preventive treatment options of preeclampsia for patients with risk factors. The establishment of a special first-trimester screening for these women should be discussed. Moreover, it is necessary to raise the awareness among physicians of these contemporary issues to guarantee the best possible medical care.

Abstract
Background: The hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome is a serious complication in pregnancy occurring in 0.5–0.9% of all pregnancies and in 10–20% of cases with severe pre-eclampsia. Previous studies described HELLP syndrome without hemolysis without any further details. Objectives: This report represents the criteria for the diagnosis of Abdelazim and AbuFaza elevated liver enzymes, low platelet count (ELLP) syndrome as a variant of HELLP syndrome. Case Reports: A 39-year-old woman, pregnant 32 weeks’ gestation, previous five cesarean sections, admitted with severe pre-eclampsia (blood pressure 160/110 mmHg, proteinuria +3, 700 mg proteins/24 h urine, and protein/creatinine ratio ≥0.9 in spot urine sample). Laboratory investigation showed elevated liver enzymes, low platelet (PLT) count, and no evidence of hemolysis. A 31-year-old woman, pregnant 33+4 weeks’ gestation, previous one cesarean section, admitted with severe pre-eclampsia (blood pressure 170/120 mmHg, proteinuria +2, 1200 mg proteins/24 h urine, and protein/creatinine ratio 1.1 in spot urine sample). Laboratory investigations showed elevated liver enzymes, low PLT count, and no evidence of hemolysis. Both patients delivered by cesarean section after stabilization of their blood pressure and dexamethasone for induction of fetal lung maturity and MgSO4 for prevention of eclampsia. Both patients had uneventful intraoperative and postoperative stay in the hospital. The liver enzymes and the PLT count were completely normal on the 5th postoperative day, and they were discharged from the hospital in good general condition. Conclusion: Abdelazim and AbuFaza ELLP syndrome is variant of HELLP syndrome without hemolysis in women with severe pre-eclampsia. Abdelazim and AbuFaza ELLP syndrome diagnostic criteria are as follows: (1) Elevated liver enzymes; (2) Low PLT count; and (3) Absence of hemolysis (normal total and unconjugated bilirubin, absence of schizocytes, and polychromatic red cells in peripheral blood smear, and normal reticulocyte count).

Abstract
TTP is characterized by microangiopathic hemolytic anemia and thrombocytopenia associated with brain and kidney dysfunction. It occurs due to ADAMTS13 deficiency. TTP-like syndrome occurs in critically ill patients with the similar hematologic changes and additional organ dysfunction syndromes. Vascular microthrombotic disease (VMTD) includes both TTP and TTP-like syndrome because their underlying pathology is the same disseminated intravascular microthrombosis (DIT). Microthrombi are composed of platelet-unusually large von Willebrand factor multimers (ULVWF) complexes. TTP occurs as a result of accumulation of circulating ULVWF secondary to ADAMTS13 deficiency. This protease deficiency triggers microthrombogenesis, leading to "microthrombi" formation in microcirculation. Unlike TTP, TTP-like syndrome occurs in critical illnesses due to complement activation. Terminal C5b-9 complex causes channel formation to endothelial membrane, leading to endotheliopathy, which activates two different molecular pathways (i.e., inflammatory and microthrombotic). Activation of inflammatory pathway triggers inflammation. Activation of microthrombotic pathway promotes platelet activation and excessive endothelial exocytosis of ULVWF from endothelial cells (ECs). Overexpressed and uncleaved ULVWF become anchored to ECs as long elongated strings to recruit activated platelets, and assemble "microthrombi". In TTP, circulating microthrombi typically be lodged in microvasculature of the brain and kidney, but in TTP-like syndrome, microthrombi anchored to ECs of organs such as the lungs and liver as well as the brain and kidneys, leading to multiorgan dysfunction syndrome. TTP occurs as hereditary or autoimmune disease and is the phenotype of ADAMTS13 deficiency-associated VMTD. But TTP-like syndrome is hemostatic disorder occurring in critical illnesses and is the phenotype of endotheliopathy-associated VMTD. Thus, this author's contention is TTP and TTP-like syndrome are two distinctly different disorders with dissimilar underlying pathology and pathogenesis.

Abstract
Background The oxysterol 27-hydroxycholesterol (27-OHC) plays an important role in the regulation of cholesterol homeostasis. Pregnancy pathologies like preeclampsia (PE), HELLP-syndrome (HELLP), intrauterine growth restriction (IUGR) and intrahepatic cholestasis in pregnancy (ICP) are linked to disturbances in lipid metabolism. In the present study, we hypothesized a specific gestational regulation of 27-OHC and compromised 27-OHC levels due to placental and hepatic diseases in pregnancy resulting in a dysregulation of lipid metabolism. Methods The 27-OHC was measured by gas-chromatography-mass spectrometry (GC-MS) and related to cholesterol concentrations. In the longitudinal cohort, a complete set of samples of healthy patients (n = 33) obtained at three different time points throughout gestation and once post-partum was analyzed. In the cross sectional cohort, patients with pregnancy pathologies (IUGR n = 14, PE n = 14, HELLP n = 7, ICP n = 7) were matched to a control group (CTRL) of equal gestational ages. Results The 27-OHC levels already increased in the first trimester despite lower TC concentrations (p < 0.05). During the course of pregnancy, a subtle rise in 27-OHC concentrations results in an overall decrease of 27-OHC/TC ratio in between the first (p < 0.05) and second trimester. The ratio remains stable thereafter including the post-partum period. No significant differences have been observed in pregnancy pathologies as compared to the CTRL group. Conclusion In conclusion, 27-OHC may have a compensatory role in cholesterol metabolism early in pregnancy. The conserved 27-OHC/TC ratio in pregnancy pathologies suggest that neither the placenta nor the liver is majorly involved in the regulation of 27-OHC metabolism.

Abstract
OBJECTIVE Lipids and steroid hormones are closely linked. While cholesterol is the substrate for (placental) steroid hormone synthesis, steroid hormones regulate hepatic lipid production. The aim of this study was to quantify circulating steroid hormones and lipid metabolites, and to characterize their interactions in normal and pathological pregnancies with a focus on hepatic and placental pathologies. METHODS A total of 216 serum samples were analyzed. Group A consisted of 32 patients with uncomplicated pregnancies who were analyzed at three different time-points in pregnancy (from the first through the third trimester) and once post partum. Group B consisted of 36 patients (24th to 42nd week of gestation) with pregnancy pathologies (IUGR n = 10, preeclampsia n = 13, HELLP n = 6, intrahepatic cholestasis n = 7) and 31 controls with uncomplicated pregnancies. Steroid profiles including estradiol, progesterone, and dehydroepiandrosterone were measured by GC-MS and compared with lipid concentrations. RESULTS In Group A, cholesterol and triglycerides correlated positively with estradiol (cholesterol ρ = 0.50, triglycerides ρ = 0.57) and progesterone (ρ = 0.49, ρ = 0.53) and negatively with dehydroepiandrosterone (ρ = - 0.47, ρ = - 0.38). Smoking during pregnancy affected estradiol concentrations, leading to lower levels in the third trimester compared to non-smoking patients (p < 0.05). In Group B, cholesterol levels were found to be lower in IUGR pregnancies and in patients with HELLP syndrome compared to controls (p < 0.05). Steroid hormone concentrations of estradiol (p < 0.05) and progesterone (p < 0.01) were lower in pregnancies with IUGR. DISCUSSION Lipid and steroid levels were affected most in IUGR pregnancies, while only minor changes in concentrations were observed for other pregnancy-related disorders. Each of the analyzed entities displayed specific changes. However, since the changes were most obvious in pregnancies complicated by IUGR and only minor changes were observed in pregnancies where patients had impaired liver function, our data suggests that placental rather than maternal hepatic function strongly determines lipid and steroid levels in pregnancy.

Abstract
BACKGROUND: Preeclampsia is a hypertensive multisystem disorder of pregnancy that complicates up to 10% of pregnancies worldwide and is one of the leading causes of maternal and perinatal morbidity and mortality. AIM: To evaluate maternal complications associated with severe preeclampsia. METHODS: This is a retrospective cross-sectional study conducted in the UHOG “Koço Gliozheni”, in Tirana. Primary outcomes evaluated: maternal death, eclampsia, stroke, HELLP syndrome, and pulmonary edema. Secondary outcomes: renal failure, admission in ICU, caesarean section, placental abruption, and postpartum hemorrhage. Fisher’s exact test and Chi-squared test were used as statistical methods. RESULTS: In women with severe preeclampsia we found higher rates of complications comparing to the group with preeclampsia. Eclampsia (1.5% vs. 7.1%, P < 0.001), HELLP syndrome (2.4% vs. 11.0%; P < 0.001), stroke (0.5% vs 1.9%, P = 0.105) pulmonary edema (0.25% vs. 1.3%, P = 0.0035), renal failure (0.9% vs. 2.6%, P = 0.107), admission in ICU (19.5% vs. 71.4%, P = 0.007), caesarean section rates (55.5% vs. 77%, P = 0.508), placental abruption (4.3% vs. 7.8%, P = 0.103) and severe postpartum hemorrhage (3.2% vs. 3.9%, P = 0.628). CONCLUSION: Severe preeclampsia is associated with high rates of maternal severe morbidity and early diagnosis and timely intervention can prevent life treating complications.

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 Thrombocytopenia is, after anemia, the second most common abnormality of the complete blood count in pregnancy, with a reported frequency of 6.6% to 11.2%. It has many causes. Thrombocytopenia should be diagnostically evaluated as early as possible in pregnancy, so that the obstetrical management can be accordingly planned to minimize harm to the mother and child. As the various underlying diseases share clinical features and laboratory findings, the differential diagnosis is often a difficult interdisciplinary challenge. METHODS In this article, we review pertinent literature (2000-January 2015) retrieved by a selective search in PubMed. RESULTS Gestational thrombocytopenia is the most common type, accounting for 75% of cases, followed by severe pre-eclampsia/HELLP syndrome (hemolysis, elevated liver enzymes, low platelet count) in 15-22% and autoimmune thrombocytopenia (ITP) in 1-4%. Gestational thrombocytopenia and ITP differ in the bleeding history, the severity of thrombocytopenia, the frequency of neo - natal thrombocytopenia, and the rate of normalization of the platelet count after delivery. The HELLP syndrome and rarer microangiopathic hemolytic anemias (e.g., thrombotic thrombocytopenic purpura) can be differentiated on the basis of their main clinical features, such as hypertension/proteinuria and upper abdominal pain, the severity of hemolysis and thrombocytopenia, the degree of transaminase elevation, and the rapidity of postpartum remission of the clinical and laboratory findings. A stepwise diagnostic procedure should be followed to distinguish further causes, e.g., to differentiate thrombocytopenia due to infection, autoimmune disease, or drugs from thrombocytopenia due to a rare hereditary disease. CONCLUSION The early interdisciplinary evaluation of thrombocytopenia in pregnancy is a prerequisite for the optimal care of the mother and child. The development of evidence-based recommendations for interdisciplinary management should be a goal for the near future.

Abstract
HELLP syndrome was first described in 1982 by Weinstein et al. and the term HELLP refers to an acronym used to describe the clinical condition that leads to hemolysis, elevated liver enzymes and low platelets. The syndrome frequency varies from 0.5 to 0.9% pregnancies and manifests preferentially between the 27th and 37th week of gestation. Approximately 30% of cases occur after delivery. Although the etiopathogenesis of this syndrome remains unclear, histopathologic findings in the liver include intravascular fibrin deposits that presumably may lead to hepatic sinusoidal obstruction, intrahepatic vascular congestion, and increased intrahepatic pressure with ensuing hepatic necrosis, intraparenchymal and subcapsular hemorrhage, and eventually capsular rupture. Typical clinical symptoms of HELLP syndrome are pain in the right upper quadrant abdomen or epigastric pain, nausea and vomiting. However, this syndrome can present nonspecific symptoms and the diagnosis may be difficult to be established. Laboratory tests and imaging exams are essential for differential diagnosis with other clinical conditions. Treatment of HELLP syndrome with corticosteroids, targeting both lung maturation of the fetus is still an uncertain clinical value. In conclusion, three decades after the tireless efforts of Dr. Weinstein to characterize HELLP syndrome, it remains a challenge to the scientific community and several questions need to be answered for the benefit of pregnant women.

Abstract
BACKGROUND Postpartum hemolytic uremic syndrome (PHUS) is a severe thrombotic microangiopathy (TMA) that is clinically characterized by hemolytic anemia, renal dysfunction, and low platelet levels after childbirth. Here, we report a rare case of unexpected death due to PHUS. CASE PRESENTATION A 23-year-old parturient had an uncomplicated cesarean section at 40 weeks gestation. The immediate postpartum course was uneventful. However, eight days post delivery, the patient developed severe nausea and vomiting followed by hematuria, spontaneous bruising, marked pallor, icteric sclera, and lethargy. Laboratory findings revealed that the patient had hemolytic anemia, thrombocytopenia, and acute renal failure. This patient died approximately 29 h after the onset of symptoms. Post-mortem examination confirmed that the patient had PHUS. CONCLUSIONS This paper addresses the need for a renal histological examination in addition to a thorough clinical history and appropriate laboratory tests for the rapid and accurate diagnosis of PHUS. Early detection and diagnosis can significantly improve the prognosis and optimize maternal outcomes.

Abstract
Introduction We report the case of a patient with antepartum HELLP syndrome and simultaneous rupture of the right liver lobe. An emergency caesarean section was performed and the liver rupture was managed surgically via perihepatic packing. The mother and her child recovered well and were discharged 19 days after admission. Case Report We describe a case report and review the literature. Based on our own experience and the most common clinical presentations of such patients, we were able to establish an algorithm for managing such cases. Conclusion An association between liver rupture and HELLP syndrome is rare but was previously described in several case reports. In pregnant women with HELLP syndrome and acute onset abdominal pain, a potential spontaneous hepatic rupture should be taken into consideration.

Abstract
OBJECTIVE Most anti-angiogenic preeclampsia models in rodents utilized the overexpression of a truncated soluble fms-like tyrosine kinase-1 (sFlt-1) not expressed in any species. Other limitations of mouse preeclampsia models included stressful blood pressure measurements and the lack of postpartum monitoring. We aimed to 1) develop a mouse model of preeclampsia by administering the most abundant human placental sFlt-1 isoform (hsFlt-1-e15a) in preeclampsia; 2) determine blood pressures in non-stressed conditions; and 3) develop a survival surgery that enables the collection of fetuses and placentas and postpartum (PP) monitoring. METHODS Pregnancy status of CD-1 mice was evaluated with high-frequency ultrasound on gestational days (GD) 6 and 7. Telemetry catheters were implanted in the carotid artery on GD7, and their positions were verified by ultrasound on GD13. Mice were injected through tail-vein with adenoviruses expressing hsFlt-1-e15a (n = 11) or green fluorescent protein (GFP; n = 9) on GD8/GD11. Placentas and pups were delivered by cesarean section on GD18 allowing PP monitoring. Urine samples were collected with cystocentesis on GD6/GD7, GD13, GD18, and PPD8, and albumin/creatinine ratios were determined. GFP and hsFlt-1-e15a expression profiles were determined by qRT-PCR. Aortic ring assays were performed to assess the effect of hsFlt-1-e15a on endothelia. RESULTS Ultrasound predicted pregnancy on GD7 in 97% of cases. Cesarean section survival rate was 100%. Mean arterial blood pressure was higher in hsFlt-1-e15a-treated than in GFP-treated mice (∆MAP = 13.2 mmHg, p = 0.00107; GD18). Focal glomerular changes were found in hsFlt-1-e15a -treated mice, which had higher urine albumin/creatinine ratios than controls (109.3 ± 51.7 μg/mg vs. 19.3 ± 5.6 μg/mg, p = 4.4 x 10(-2); GD18). Aortic ring assays showed a 46% lesser microvessel outgrowth in hsFlt-1-e15a-treated than in GFP-treated mice (p = 1.2 x 10(-2)). Placental and fetal weights did not differ between the groups. One mouse with liver disease developed early-onset preeclampsia-like symptoms with intrauterine growth restriction (IUGR). CONCLUSIONS A mouse model of late-onset preeclampsia was developed with the overexpression of hsFlt-1-e15a, verifying the in vivo pathologic effects of this primate-specific, predominant placental sFlt-1 isoform. HsFlt-1-e15a induced early-onset preeclampsia-like symptoms associated with IUGR in a mouse with a liver disease. Our findings support that hsFlt-1-e15a is central to the terminal pathway of preeclampsia, and it can induce the full spectrum of symptoms in this obstetrical syndrome.

Abstract
OBJECTIVE Review the latency period after betamethasone (BMZ) for pregnancies complicated by hypertensive disorders of pregnancy (HDP). STUDY DESIGN A retrospective chart review of patients that received BMZ for the reduction of preterm morbidity for HDP. Patients were grouped by gestational age of administration of BMZ and type of hypertensive disorder of pregnancy for analysis. The primary outcome was the interval between the gestational age of the patient at BMZ administration and delivery. RESULTS One-hundred and forty-seven subjects received BMZ for HDP during the study period delivering 168 infants. The median interval between administration of BMZ and delivery was 5 days [interquartile range (IQR) 2-20 days]. The median neonatal intensive care unit length of stay (NICU LOS) was 20 days (IQR 6-33 days). Fifty-seven percent of subjects delivered within 7 days of diagnosis and 32% had a latency period >14 days. Seventy-five percent of subjects were ultimately delivered for worsening hypertension. CONCLUSIONS The median latency period between diagnosis and delivery in the setting of HDP is <7 days. Further studies are warranted to address the use of antihypertensive pharmacotherapy to prolong the latency period for fetal benefit.

Abstract
HELLP occurs in 0.5%-0.9% of all pregnancies. About 30% of the cases happen within 48 hours after delivery. Women with postpartum HELLP syndrome have significantly higher incidences of complications. Because of the absence of classical signs of preeclampsia, it can confuse physicians and lead to delay in diagnosis. Therefore, it is associated with serious maternal morbidity. We present two cases of acute postpartum HELLP syndrome after caesarean section following severe preeclampsia. Our cases were successfully managed with the timely diagnosis and therapy.

Abstract
Background The HELLP syndrome (haemolysis, elevated liver enzymes, and low-platelet count) occurs in about 0.5 to 0.9% of all pregnancies. With occurrence of thrombocytopaenia, it signals for several potentially lethal conditions such as complete or partial HELLP syndrome, thrombotic thrombocytopaenic purpura and acute fatty liver of pregnancy. Case presentation A previously healthy 27-year-old, Sinhala ethnic primigravida with pregnancy-induced hypertension was admitted at 38 weeks of gestation with lower abdominal pain and a blood pressure of 140/90 mmHg. She underwent emergency Caesarian section due to faetal distress giving birth to a healthy baby girl. Since postpartum day one, she was having intermittent fever spikes. All the routine investigations were normal in the first three weeks. Platelet count started dropping from post-partum day-20 onwards. On day-23, she had developed a seizure and computed tomography scan brain showed a subdural haemorrhage. She had a platelet count of 22,000 × 109/liter and was managed conservatively. She also had elevated liver enzymes, lactate dehydrogenase and bilirubin levels. Blood picture on day-24 showed haemolytic anemia. On day- 36, patient again developed seizures and she was having intermittent fever with generalized headache and signs of meningism. Computed tomography scan revealed an acute on chronic subdural haemorrhage. Conclusions Hypertensive disorders in pregnancy should be managed as high-risk throughout the postpartum period. Development of thrombocytopaenia can be considered as an early warning sign for HELLP, thrombotic thrombocytopaenic purpura or acute fatty liver of pregnancy which are lethal conditions. Prompt recognition of intracranial haemorrhages and early neurosurgical intervention is lifesaving.

Abstract
Unexpected rapid maternal death after delivery due to HELLP syndrome is rarely encountered and may become the subject of forensic expertise. Unexpectedness, suddenness, and fulminant course of this syndrome as well as absence of classical signs of pre-eclampsia can confuse physicians and lead to diagnostic delay. A definitive post-mortem diagnosis of HELLP syndrome in questionable cases of maternal death should be based on accepted laboratory criteria and characteristic histopathological alterations. We present a case of acute postpartum HELLP syndrome complicated by disseminated intravascular coagulation and acute renal failure which caused rapid maternal death only 20 hours after a caesarean section following an uncomplicated pregnancy.

Abstract
Background: Arterial hypertension is one of the most important causes of cardiovascular diseases, and the latter are responsible for almost half of the deaths in the industrialised nations. Hypertensive disorders of pregnancy constitute one of the most frequent causes of feto-maternal morbidity and mortality; on the other hand the occurrence of a hypertensive disorder of pregnancy represents a risk for the later development of hypertension and the cardiovascular risks resulting therefrom. The aim of this article is to demonstrate the association of hypertensive disorders of pregnancy with consecutive cardiovascular diseases. Materials and Methods: Specific selective literature research. Results: After the occurrence of a hypertensive disorder of pregnancy the relative risks for hypertension are 3.7 (2.70-5.05), for ischaemic heart disease 2.2 (1.86-2.52), for cerebral insult 1.8 (1.45-2.27) and for mortality resulting from cardiovascular causes 1.5 (1.05-2.14) and are thus significant. According to a recent study 56 % of internal specialists and 23 % of gynecologists do not know about the association of preeclampsia with ischemic heart disease, 48 % and 38 % respectively are not aware of the link with stroke and 79 % and 77 % respectively are not aware of the association with a reduced life expectancy after preeclampsia. The presence of hypertension is not known by many of the patients, merely 28-38 % receive an appropriate therapy. Conclusion: Adequate follow-up after hypertensive disorders of pregnancy and the early recognition of and therapy for hypertension represent the cornerstones in the prevention of late cardiovascular sequelae. General practitioners, specialist for internal medicine and gynaecologists have a special responsibility with regard to the reduction of later complications.

Abstract
Purpose In this study, we aimed to investigate the perinatal clinical conditions of very low birth weight (VLBW) infants born to mothers with pregnancy-induced hypertension (PIH) focusing on the effects of early postnatal neutropenia. Methods We reviewed the medical records of 191 VLBW infants who were born at Konyang University Hospital, between March 2003 and May 2011. We retrospectively analyzed the clinical characteristics of the infants and their mothers and compared the incidence of perinatal diseases and mortality of the infants according to the presence or absence of maternal PIH and neutropenia on the first postnatal day. Results Infants born to mothers with PIH showed an increased incidence of neutropenia on the first postnatal day (47.4%), cesarean delivery, and intrauterine growth restriction. When the infants born to mothers with PIH showed neutropenia on the first postnatal day, their incidence of respiratory distress syndrome (RDS) was increased (P=0.031); however, the difference was not found to be significant through logistic regression analysis. In all the VLBW infants, neutropenia on the first postnatal day was correlated with the development of RDS. The incidence of the other perinatal diseases involving sepsis and mortality did not significantly differ according to the presence or absence of neutropenia in infants born to mothers with PIH. Conclusion In VLBW infants born to mothers with PIH, the incidence of neutropenia on the first postnatal day was increased and it was not significantly correlated with the development of perinatal diseases involving RDS, sepsis, and mortality.

Abstract
OBJECTIVE The diagnostic value of affinity-based matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis to distinguish preeclampsia (PE) from matched controls was tested in a multicenter setting. METHODS Serum samples of preeclamptic (n = 60) and healthy pregnant women (n = 66) from four centers were prospectively analyzed with predefined rule sets. RESULTS Overall sample classification reached sensitivity of 0.88 and specificity of 0.73. Separate calculations for early-onset PEs only (before 34 weeks of gestation) revealed sensitivity of 0.88 and specificity of 0.89. CONCLUSION Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry serum-profiling with center-wise standardization offers a fast and robust method to classify PE and contributes to the theory of PE being a heterogeneous disorder that ought to be subclassified.

Abstract
OBJECTIVE To investigate placental protein 13 (PP13) localization in relation to cytoskeleton and lipid rafts in preeclampsia and HELLP syndrome. STUDY DESIGN Placental cryosections from patients with preeclampsia and HELLP, and controls were stained for PP13, actin, PLAP (lipid raft marker), and CD71 (nonraft marker). BeWo cells exposed to stress conditions were stained for PP13 and actin. Protein localizations were investigated by confocal microscopy, PP13 concentrations by ELISA. RESULTS PP13-actin colocalization was increased in syncytiotrophoblast juxtamembrane regions in term/preterm preeclampsia and HELLP. PP13-CD71 colocalization was decreased and PP13-PLAP proximity was increased in preterm but not term preeclampsia and HELLP. PP13-release from BeWo cells was inhibited by cytoskeleton disruption, and augmented by Ca2+-influx and ischemic stress. CONCLUSION The actin cytoskeleton, probably in connection with lipid rafts, controls trophoblastic "nonclassical" PP13 export. PP13 is released from the syncytiotrophoblast in preterm preeclampsia and HELLP, mimicked in BeWo cells by ischemic stress, suggesting PP13 is a placental alarmin.

Abstract
The HELLP syndrome is a serious complication of pregnancy characterized by hemolysis (H), elevated liver (EL) enzymes, and low platelet (LP) count that occurs in 0.2-0.6% of all pregnancies and in 10-20% of cases with severe preeclampsia and frequently leads to adverse maternal and perinatal outcome. The exact pathobiology of HELLP syndrome has not been clearly defined. As it is considered a form or a complication of severe preeclampsia, it likely has its origin in aberrant placental development and function resulting in ischemia-producing oxidative stress. However, there is still a debate on whether HELLP must be considered a severe form of preeclampsia or a separate disease entity. It can be described as a placenta-induced disease, as is preeclampsia itself, but with a more acute and predominant inflammatory process typically targeting the liver and with a greater activation of the coagulation system. This occurs during a disordered immunologic process and may be due to a genetic predisposition. In this review, we discuss the main biochemical characteristics of HELLP syndrome, particularly focusing on molecular aspects of placental involvement and maternal systemic responses.

Abstract
A multifactorial differential analysis of serum proteins using mass spectrometry distinguished samples from pregnant women with severe early-onset preeclampsia (n = 11) from those of control individuals with uneventful pregnancies (n = 13). Serum proteins were fractionated by either their affinities to reversed-phase material coated magnetic beads or by fractionated precipitation. The on-average most abundant ion signals were observed at m/z 9390, 9103, and 8886. The best differentiating ion signals between the two sample groups were found at m/z 13,715, 13,834, and 13,891. The normalized intensities of these ion signals were on-average lower in the preeclampsia group than in the control group. The six ion signal intensities enabled sorting of the individual spectra with high accuracy. Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed that a protein band migrating just above the 14 kDa marker band contained transthyretin (P02766; M(r) (avg.): 13,761). Densitometric analysis of the transthyretin bands showed lower intensities in the preeclampsia samples with respect to those of the controls. Nephelometric analysis of the serum samples determined the mean concentration of transthyretin in the preeclampsia group were lower (0.16 mg/mL; range: 0.13 to 0.20; SD: 0.03) than that in the control group (0.19 mg/mL; range: 0.14 to 0.22; SD: 0.02), substantiating the role of transthyretin concentration differences in the comparison of the two groups. Altogether, our findings support the theory of preeclampsia being a heterogeneous disorder that might be sub-classified by a defined proteome signature in maternal blood using multifactorial analysis of affinity-fractionated serum samples.

Abstract
Thrombotic microangiopathies are rare conditions characterized by microangiopathic hemolytic anemia, microthrombi, and multiorgan insult. The disorders, which include hemolytic uremic syndrome and thrombotic thrombocytopenic purpura, are often acute and life threatening. We report a retrospective analysis of 65 patients presenting to our institution from 1997 to 2008 with all forms of thrombotic microangiopathy. Therapeutic plasma exchange was a requirement for analysis and 65 patients were referred to our institution; 66% of patients were female and median age at presentation was 52 years. Bacterial infection was the most commonly identified etiologic factor and in the multivariate model was the only significant variable associated with survival outcome (odds ratio 5.1, 95% confidence interval, 1.2-21.7). As infection can be considered a common trigger event for thrombotic microangiopathy, patients with hepatobiliary sepsis may benefit from elective cholecystectomy. We conclude that bacterial infection frequently triggers TTP and other thrombotic microangiopathies in patients with preexisting risk factors and propose a model for the development of these syndromes.

Abstract
PURPOSE To evaluate the maternal and fetal outcome in 44 pregnancies complicated with HELLP syndrome and to investigate the role of platelet counts in its prognosis. METHODS A retrospective analysis of the medical records of 44 patients with the diagnosis of hemolysis elevated liver enzymes and low platelet count between June 1997 and January 2009 was performed. The patients were divided into two groups according to blood platelet count: platelet count <50,000 mm(3) formed Group I and platelet count 50,000-100,000 mm(3) formed Group II. Clinical findings and laboratory characteristics, maternal complications, perinatal outcomes and comparison of maternal and fetal morbidity according to platelet counts were analyzed. RESULTS During the period of 12 years, 44 (0.54%) of 8,132 deliveries had HELLP syndrome. Among 44 patients, the most common complications were disseminated intravascular coagulopathy (18.2%), acute renal failure (15.9%), abruptio placentae (11.4%), and cerebral hemorrhage/infarction (11.4%). Maternal and perinatal mortality rates in HELLP syndrome were 9.1 and 40.9%, respectively. Aspartate aminotransferase levels were found to be statistically significantly higher in Group I (p = 0.04). While disseminated intravascular coagulopathy and acute renal failure were statistically significantly higher in Group I (p = 0.01; p = 0.03 respectively), fetal growth restriction was statistically significantly higher in Group II (p = 0.04). CONCLUSIONS HELLP syndrome is associated with high incidences of maternal and fetal morbidity and mortality and patients with low platelet counts might have a much increased risk.

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
A woman at 16 weeks of gestation was admitted to our perinatal center with unspecific abdominal pain. The results from blood samples 12 h after admission revealed a fulminant HELLP-syndrome. After starting i.v. corticosteroid therapy, the woman recovered quickly. CVS was performed because of abnormal findings by ultrasound and a fetal triploidy (69, XXX) was diagnosed. Pregnancy was terminated and histopathological examination of the placental tissue confirmed a partial mole.

Abstract
INTRODUCTION HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count) is a severe, life-threatening form of preeclampsia. Its development is accompanied by significant increase in maternal, as well as fetal, morbidity, and mortality rates. It is essential, therefore, for obstetricians to be familiar with the disease. MATERIALS AND METHODS In the past 10 years, 107 patients were treated for HELLP syndrome in the intensive care unit (ICU) of the First Department of Obstetrics and Gynaecology, Semmelweis University. During this time, we studied the characteristic laboratory findings of the disease from the day of the diagnosis until the first few postpartum days. RESULTS HELLP syndrome was present in 0.37% of all women having live births. In our study, the liver enzymes AST, and LDH, and the level of total bilirubin (indicating the degree of hemolysis), and repeated thrombocyte counts were suitable for following the cases. The AST, LDH and bilirubin levels returned to normal between the third and seventh days postpartum. The platelet count passed the critical level of 100,000/microL on the third to fourth day. CONCLUSIONS We have found that the platelet count, LDH, AST, and total bilirubin levels proved to be useful indicators of the progression of HELLP syndrome.

Abstract
Plasminogen activator inhibitor-1 (PAI-1) is a major inhibitor of fibrinolysis, and a single nucleotide insertion/deletion (4G/5G) polymorphism in the promoter region of the PAI-1 gene has been identified. Subjects homozygous for the 4G allele have the highest PAI-levels due to increased PAI-1 gene transcription. Pre-eclampsia, and one of its most severe forms, the HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome, are characterized by increased placental thrombosis based on a procoagulatory state in the mother. Several studies have investigated the role of the PAI-1 4G/5G polymorphism in pre-eclampsia, but no study has focused especially on HELLP syndrome. Therefore we aimed to assess the association between HELLP syndrome and the 4G/5G polymorphism in the PAI-1 gene. Genotyping of the PAI-1 4G/5G promoter polymorphism was performed in 102 Caucasian women with HELLP syndrome and 102 Caucasian women with uncomplicated pregnancies. The 4G/4G genotype was more frequent in women with HELLP syndrome than in controls (35.3% vs. 22.5%, respectively) but this difference was not significantly different (P = 0.129). The frequency of the 4G allele was 0.588 in patients and 0.515 in controls. These data suggest that women carrying a 4G/4G genotype of the PAI-1 gene are not at increased risk for developing HELLP syndrome and are thus in line with the majority of previous studies on the association between the PAI-1 4G/5G polymorphism and pre-eclampsia.

Abstract
The HELLP syndrome as part of the microangiopathic syndromes requires special attention in terms of a rapid and accurate diagnostic and differential diagnostic workup because of its possibly rapid clinical deterioration. It is defined by the classical triad of hemolysis,elevated liver enzymes and low platelet counts which may lead to prognostically relevant problems in differentiating it from thrombotic-thrombocytopenic purpura and hemolytic-uremic syndrome and other pregnancy-related and unrelated liver diseases, i.e. mainly clinical and laboratory similarities to other liver diseases such as acute fatty liver or intrahepatic cholestasis in pregnancy or pregnancy-unrelated settings like viral hepatitides. The management in the different phases of pregnancy is described in detail. Therapeutic options to prolong pregnancy are discussed as are the possibilities of prophylaxis in subsequent pregnancies and aspects of the followup.
