Maternal risk factors and adverse birth outcomes associated with HELLP syndrome: a population-based study.

OBJECTIVES: We assessed the incidence, risk factors and adverse birth outcomes associated with elevated liver enzymes and low platelets (HELLP) syndrome. DESIGN: A retrospective population-based cohort study. SETTING: Canada (excluding Quebec), 2012/2013-2015/2016. POPULATION: Mothers with a singleton hospital live birth or stillbirth at ≥24 weeks' gestation (n = 1 078 323). METHODS: HELLP syndrome was identified using ICD-10-CA diagnostic code from delivery hospitalisation data. We used logistic regression to identify independent risk factors for HELLP syndrome by obtaining adjusted odds ratios (AOR) and 95% confidence intervals (CI), and to assess the associations with adverse outcomes. MAIN OUTCOME MEASURES: Adverse maternal (e.g. eclampsia) and fetal/neonatal outcomes (e.g. intraventricular haemorrhage, perinatal death). RESULTS: The incidence of HELLP syndrome was 2.5 per 1000 singleton deliveries (n = 2663). Risk factors included: age ≥35 years, rural residence, nulliparity, parity ≥4, pre-pregnancy and gestational hypertension and diabetes, assisted reproduction, chronic cardiac conditions, systemic lupus erythematosus, obesity, chronic hepatic conditions, placental disorders (e.g. fetomaternal transfusion) and congenital anomalies. PROM and age <25 years were inversely associated with HELLP syndrome (P-values <0.05). Women with the syndrome had a 10-fold higher maternal mortality (95% CI 1.6-84.3) and elevated severe maternal morbidity (9.6 versus 121.7 per 1000; AOR 12.5, 95% CI 11.1-14.1); and higher perinatal mortality (4.3 versus 21.0 per 1000; AOR 4.5, 95% CI 3.5-5.9) and perinatal mortality/severe neonatal morbidity (21.2 versus 202.4 per 1000; AOR 10.7, 95% CI 9.7-11.8). CONCLUSION: HELLP syndrome is associated with specific pre-pregnancy and pregnancy risk factors, higher rates of maternal death, and substantially higher severe maternal morbidity, perinatal mortality and severe neonatal morbidity. TWEETABLE ABSTRACT: HELLP syndrome is associated with higher maternal death rate, and substantially higher severe maternal and neonatal morbidity, and perinatal mortality.

Aspartate-aminotransferase to platelet ratio index score for predicting HELLP syndrome.

INTRODUCTION: HELLP (hemolysis, elevated liver enzyme levels, low platelet counts)-syndrome is a rare but dramatic pregnancy-related illness. The difficult part of this syndrome is the lack of standardised diagnostic criterias and tests to be used to predict it. The aim of this study is determining the role of APRI score in the diagnosis of HELLP syndrome. MATERIAL AND METHODS: In this cross sectional, retrospective study, patients with HELLP syndrome as case group and age-matched healthy pregnants at the similar pregnancy trimester as control group were included between January 12,017 and May 31, 2018. Data including sex, age, laboratory values, prognosis were recorded from the computerized system of the hospital. The p-value <0.05 was considered statistically significant. RESULTS: 40 patients with HELLP syndrome and 124 age-matched healthy pregnants included in the study. There was a statistically significant difference between control group and HELLP patients in terms of the mean urinary protein, platelet count, ALT, AST, creatinin, D dimer levels and also the mean APRI score. In the multivariate regression analysis, APRI score was found a better predictor than AST and both were in a good significant in predicting HELLP. On the ROC curve in order to distinguish the patients with HELLP from the control group for AST and APRI score, the sensitivity was found to be 71.7% and 82.6%, specificity to be 91.2% and 87.6% respectively. Maternal mortality rate of HELLP syndrome was 10%. CONCLUSION: We concluded that the APRI score was robustly predicted HELLP syndrome than AST alone in this study. Further studies are needed to support our data with prospective, multicentre, larger patient groups.

Maternal, fetal, and neonatal outcomes among different types of hypertensive disorders associating pregnancy needing intensive care management.

Objective: To assess the relationship between maternal, fetal, and neonatal outcomes and different forms of hypertensive disorders associating pregnancy in women needed intensive care units (ICUs) admission.Methods: A prospective case control study was conducted on 1238 women admitted to hypertensive ICU at three university hospitals. They were classified into four groups. Group I included 472 women with severe preeclampsia (PE), Group II included 243 women with eclampsia (E), Group III included 396 women diagnosed with E associated with HELLP syndrome, and Group IV included 127 women diagnosed as HELLP syndrome. All women received magnesium sulfate to prevent and/or control convulsions and nifedipine to control their blood pressure. Primary outcome parameter was maternal mortality. Other outcomes included maternal morbidities, fetal, and neonatal outcomes.Results: There was a significant difference among the study groups regarding the need for blood transfusion (58.1%, 70%, 84.3%, and 42.5% respectively, p < .001), number of transferred units (2.4 ± 1, 2.9 ± 0.9, 3.4 ± 1.1, and 3.5 ± 0.8 respectively, p < .001), placental abruption (23.3%, 16.5%, 30.3%, and 19.7% respectively, p < .001), pulmonary edema (14.8%, 22.6%, 19.9%, and 34.6% respectively, p < .001), multiple complications (12.5%, 12.3%, 19.9%, and 26% respectively, p < .001), and maternal mortality (1.9%, 4.1%, 6.1%, and 5.5% respectively, p < .001). Regarding fetal and neonatal outcomes, there was a significant difference among the four groups regarding Apgar score at 1 and 5 min, neonatal birth weight, neonatal intensive care unit (NICU) admission, NICU admission days, intrauterine growth restriction, perinatal death, respiratory distress syndrome, intraventricular hemorrhage, sepsis, and the need for mechanical ventilation (p < .001). Higher rate of vaginal delivery was reported in women with HELLP (40.9%) and severe PE (39.8%) and higher rates of performing cesarean section (CS) in women with eclampsia (77.8%). Maternal mortality is significantly related to delivery with CS, younger maternal age with lower parity, and the presence of placental abruption or pulmonary edema. For Groups III and IV, which included HELLP cases, there are significant differences between both groups as regards HELLP classes according to Mississippi classification, also significant differences were seen between both groups as regards, maternal mortality, abruptio placenta, pulmonary edema, multiple organ damage, NICU admission, perinatal deaths, and need for mechanical ventilation.Conclusion: Both maternal mortality and morbidity (placental abruption and need for blood transfusion) are significantly higher in women with HELLP syndrome worsens to become class 1 regardless of whether eclampsia is present or not.Synopsis: Maternal mortality and unfavorable outcome are significantly higher in women with HELLP syndrome whether it was associated with eclampsia or not.

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.

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.

Acute kidney injury in patients with HELLP syndrome.

PURPOSE: To evaluate the risk factors and renal prognosis of acute kidney injury (AKI) in patients with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. METHODS: Women with HELLP syndrome over a 15-year period at Peking Union Medical College Hospital, China, were retrospectively studied. RESULTS: A total of 108 patients with HELLP syndrome were included. Fifty-two (48.1%) patients were diagnosed with AKI (median serum creatinine, 139.72 µmol/L; range, 89.00-866.00); 11 (21.2%) required hemodialysis. The AKI group had significantly more multiparity (p = 0.034), hemorrhage > 400 mL (p = 0.027), severe systolic hypertension ≥ 160 mmHg (p = 0.005), infection (p < 0.001), and low hemoglobin (p = 0.002) than non-AKI patients. Multivariate logistic regression showed that infection (OR 36.441, 95% CI 3.819-347.732, p = 0.002), severe systolic hypertension (OR 5.295, 95% CI 1.795-15.620, p = 0.003), and low hemoglobin (OR 0.960, 95% CI 0.932-0.988, p = 0.006) were independent risk factors for AKI. Six patients with AKI died (mortality rate: 11.5%); no death occurred among patients without AKI. In addition to infection (OR 16.268, CI 1.334-198.385, p = 0.029) and eclampsia (OR 69.895, CI 2.834-1723.910, p = 0.009), elevated serum creatinine (OR 1.006, CI 1.001-1.011, p = 0.031) was an independent predictor of maternal mortality. Renal function in 43 (82.7%) patients completely recovered. Two (3.8%) patients developed chronic renal dysfunction after 1 to 2 years of follow-up. CONCLUSIONS: Elevated creatinine was an independent predictor of maternal mortality in HELLP syndrome. AKI severely affects renal prognosis and mortality in pregnant women. The occurrence of AKI was related to infection, severe hypertension, and renal ischemia.

Hepatic rupture associated with preeclampsia, report of three cases and literature review.

BACKGROUND: Hepatic rupture is a complication during pregnancy that, although rare, accounts for high morbidity and mortality rates. It is mainly associated with severe preeclampsia and HELLP syndrome. Incidence is estimated to be at one per 67,000 births or one per 2000 patients with preeclampsia/eclampsia/HELLP, mainly in multiparous women; women in their 40s; after 32 weeks of gestation; and during the first 15 h postpartum. CASES: This article exposes the institutional experience at Fundación Valle del Lili in Cali, Colombia, in managing and treating hepatic rupture associated with severe preeclampsia and HELLP syndrome in three patients in the 30th, the 26th, and the 27th week of gestation, not resulting in maternal death. DISCUSSION: A search in Pubmed, Embase, and Ovid from 2000 to 2017 resulted in 35 cases reported in either pregnant or puerperal women. Hepatic rupture is a rare complication in pregnancy associated with preeclampsia and HELLP syndrome. Its pathophysiology is attributed to the presence of vasospasm due to an increase in concentration and sensitivity to circulating vasopressors during pregnancy. There is no standard management, but surgery reduces mortality significantly. It includes endovascular management, partial hepatectomy, or transplant (only one patient required a liver transplant in our search). The most used techniques have been ligation of the hepatic artery, embolization of the hepatic artery, and examination, packing, and drainage of hepatic lesion for bleeding control (27 cases were treated with laparotomy with evacuation of hematoma and hemostasis and four cases were treated with embolization of the hepatic artery). Hepatic artery occlusion both by surgery ligation and by embolization through interventional radiology has reported successful and failing results during pregnancy Conclusion: Management of pathologies as hepatic rupture associated with severe preeclampsia and HELLP syndrome has to be clearly protocolized for prompt diagnosis and early management. Furthermore, it has to be carried out through multidisciplinary teams in high-complexity obstetrics scenarios.

Analysis of preventability of hypertensive disorder in pregnancy-related maternal death using the nationwide registration system of maternal deaths in Japan.

Objective: Hypertensive disorder of pregnancy (HDP) is a major cause of maternal death. The goal of this study was to investigate factors associated with maternal death due to HDP. Study design: HDP-related maternal deaths in Japan reported to the Committee of the Ministry of Health, Labor and Welfare from 2010 to 2015 were examined. Results: Out of 47 cases of HDP, 30 were identified as the major cause of maternal death. The median maternal age was 34 years (range 24-45) and the mortality in women aged ≥40 years was seven times higher that than in women aged <34 years. The etiologies were intracerebral hemorrhage (n = 22), subarachnoid hemorrhage (n = 3), subcapsular hematoma of the liver (n = 2), peripartum cardiomyopathy (n = 2), and eclampsia (n = 1), and 19 cases were deemed preventable. The most frequent antepartum problems were delays in hospitalization, maternal transfer, and termination of pregnancy. In four cases, diagnosis of HELLP syndrome was too late because laboratory data were not checked, despite the patient reporting epigastric pain or showing elevation of blood pressure (BP). Treatment for lowering of BP was improper in 2/3 intrapartum cases, even though BP was elevated during pregnancy (144 versus 188 mmHg, p < .001). There was inadequate lowering of BP and lack of use of magnesium sulfate in 7/11 postpartum cases (64%), despite aspartate aminotransferase (AST) (p < .005), alanine aminotransferase (ALT) (p < .01), lactate dehydrogenase (LDH) (p < .005), and platelet count (PLT) (p < .01) all significantly worsening after delivery. Conclusion: HDP accounts for 11% of maternal deaths in Japan. Mothers aged ≥40 years are most at risk for HDP-related maternal death. Major concerns for preventabilities were late hospitalization, maternal transportation, and termination of pregnancy for term or near-term HDP. Regular vital checks and prompt lowering of BP were lacked during labor in most cases. HELLP syndrome should be managed at a general hospital with sufficient medical resources.

Niveles plaquetarios y marcadores de disfunción endotelial multiorgánica en síndrome HELLP / Platelet levels and multiorganic endothelial dysfunction markers in the Hellp Syndrome (Hemolysis, elevated liver enzimes, low platelets)

HELLP syndrome (hemolysis, elevated liver enzimes, low platelets count) is one of the major complications of the progression of thrombotic microangiopathies characterized by thrombocytopenia, hemolistic anemia and organic dysfunction. It can be found in between 0,5 - 0,9 % of all pregnancies, and between 4- 14 % in all those women who develop preeclampsia. The general objectives of this report were to describe the relationship existing between the platelet levls and the organic endothelial dysfunction because of the HELLP syndrome, and to determine the perinatal results, during the 10 yr. period of the study, in patients that were assited between 2007 and 2016.

Hemolysis, elevated liver enzymes, and low platelet syndrome: Outcomes for patients admitted to intensive care at a tertiary referral hospital.

PURPOSE: The aim was to assess outcomes for pregnancies in which hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome develops and the patient requires transfer for critical care. MATERIALS AND METHODS: The cases of women with HELLP syndrome who delivered at our tertiary center or surrounding hospitals and were admitted to the intensive care between January 2007 and July 2012 were retrospectively analyzed. Results were compared for the surviving and non-surviving patients. RESULTS: Among the 77 women with HELLP syndrome, maternal mortality rate was 14% and 24 (30%) of 81 fetuses and newborns died in the perinatal period. The most common maternal complications were disseminated intravascular coagulation (DIC) (n = 22; 29%), acute renal failure (n = 19; 25%), and postpartum hemorrhage (n = 16; 21%). Compared with surviving women, the non-surviving women had higher mean international normalized ratio (INR) (p < 0.0001); higher mean serum levels of aspartate aminotransferase (AST) (p < 0.0001); higher alanine aminotransferase (ALT) (p < 0.0001); higher lactate dehydrogenase (LDH) (p < 0.0001), and higher bilirubin (p = 0.040) levels; and lower platelet count (p = 0.005). CONCLUSION: DIC is a major risk factor for maternal outcome among patients with HELLP syndrome who require intensive care. Low platelet count; high AST, ALT, LDH, INR; and total bilirubin are associated with high mortality risk in this patient group. In addition, low platelet count; low fibrinogen level; prolonged activated thromboplastin time; high INR; and high total bilirubin, LDH, blood urea nitrogen, and creatinine are associated with high risk for complications in this patient group.

Maternal-fetal prognosis in HELLP syndrome in a level 3 maternal-fetal care centre.

PURPOSE OF INVESTIGATION: The purpose of this study was to evaluate the maternal and perinatal outcome and prognosis in pregnant women with HELLP syndrome. MATERIALS AND METHODS: Medical records of eligible pregnant women with HELLP syndrome were reviewed retrospectively. Patients were evaluated in terms of maternal complication, as well as the types of delivery. Perinatal outcome were evaluated in terms ofApgar score, birth weight, respiratory distress syndrome, and neonatal intensive care unit admission. RESULTS: The leading maternal complications associated with HELLP syndrome were the following: severe preeclampsia, eclampsia, placental abruption, acute pulmonary edema, acute kidney failure, disseminated intravascular coagulation syndrome, and immediate maternal death. The most prominent neonatal outcomes associated with HELLP syndrome were: antenatal fetal death, intrauterine growth restriction, prematurity. CONCLUSION: The management and delivery of the patients with HELLP syndrome must take place in a tertiary referral maternal and fetal care centre.

MÉTODOS: Investigación descriptiva con diseño retrospectivo, donde se revisaron las historias clínicas de gestantes ingresadas a la UCIO con diagnóstico de SH, analizándo sus características clínicas y epidemiológicas. RESULTADOS: Hubo una prevalencia del 13,60% (111/816), tasa de letalidad de 1,23% (10/8l6) y tasa de mortalidad materna específica de 15,08/100.000 nacidos vivos. Las características clínicas más prevalentes fueron: edad 25,8 ± 6,9 años, estancia en UCIO 4,76 ± 4,46 días, embarazos pretérminos 69,37%, antecedentes de abortos 24,32%, primíparas 42,34%, control prenatal ausente o inadecuado, embarazos simples 95,5%, preeclámpticas 67,57%, antecedentes de condiciones preexistentes 47,75%, sin hábitos como tabaco o alcohol 81,99%, ingresaron embarazadas 89,19% y cesárea 74,77%. Se diagnosticaron mayoritariamente casos de SH incompleto (56,76%), siendo las complicaciones más observadas la disfunción hematológica (98,2%), disfunción hepática (91,9%) y disfunción renal (70,3%). CONCLUSIÓN: La prevalencia de SH resultó más elevada que lo reportada en estudios nacionales e internacionales, presentando características clínicas y epidemiológicas que deben ser consideradas para su prevención y diagnóstico precoz.

AIMS: To determinate the prevalence of HELLP syndrome (HS) in critical pregnant women admitted to the Obstetrics Intensive Care Unit (OICU) of the "Maternidad Dr. Armando Castillo Plaza", in Maracaibo, Zulia state, Venezuela, during 2011 to 2015. METHODS: A descriptive research with retrospective design was due, in which were reviewed the clinical files of all pregnant admit into the OICU complicated with HS, was analyzed establish the clinical and epidemiological features. RESULTS: We found a prevalence of 13.60% (111/816), fatality rate of 1.23% (10/816) and specific maternal mortality rate of 15.08/100,000 live births. The most prevalent clinical characteristics were: age 25.8 ± 6.9 years, stay in UCIO 4.76 ± 4.46 days, pre-terms pregnancies (69.37%), history of abortions (24.32%), primiparous (42.34%), absent or inadequate prenatal care, singleton pregnancies (95.50%), preeclampsia (67.57%), history of pre-existing conditions (47.75%), without habits such as tobacco or alcohol (81.99%), admitted pregnant (89.19%) and cesarean section (74.77%). Also, were mainly diagnosed cases of incomplete HS (56.76%); the most observed com-plications were hematologic dysfunction (98.2%), liver dysfunction (91.9%) and renal dysfunction (70.3%). CONCLUSION: The prevalence of HELLP syndrome was higher than reported in national and international studies, presenting clinical and epidemiological characteristics that should be considered for prevention and early diagnosis.

HELLP syndrome is still a serious, life-threatening complication of pregnancy: admission of 34 women to an eastern Turkish intensive care unit.

OBJECTIVE: The transfer of the obstetric patient to the intensive care unit is considered as an indicator of maternal morbidity. The most important two indications for admittance of the obstetric patient to the intensive care unit are postpartum hemorrhage and hypertensive disorders. The purpose of this study was to determine maternal morbidity and mortality rates in patients diagnosed with hemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome who required intensive care. MATERIALS AND METHODS: The charts of 34 patients who were diagnosed with HELLP syndrome and treated in intensive care unit between the years 2005 - 2013 were evaluated retrospectively. RESULTS: During the study period, a total of 151 patients were diagnosed with HELLP syndrome and 34 patients were admitted to the intensive care unit. Mean age of the patients was 28.97 ± 7.26 years and there was no significant difference be- tween survivors and non-survivors (p = 0.442). There were no significant differences between survivors and non-survivors in terms of gestational age, parity, and multiparity rates (p > 0.05). There was 31.2% mortal cases and 77.8% of living cases had received regular antenatal follow-up and the difference was statistically significant (p = 0.006). 30 patients (88.2%) required invasive mechanical ven- tilation. The average Glasgow Coma Score (GCS) of patients was 6.47 ± 4.34. There were significant differences between patients who lived and who died in terms of Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) score, and duration of invasive mechanical ventilation (p < 0.05). Twenty-two patients (64.7%) required transfusion of blood and blood products. Maternal mortality occurred in 16 patients (47%). The causes of death were: intracerebral hemorrhage in six cases, acute respiratory distress syndrome (ARDS) in three cases, disseminated intravascular coagulation (DIC) in three\cases, sepsis/multi- ple organ dysfunction syndrome (MODS) in two cases, hepatic rupture in one case, and massive pulmonary embolism in one case. Con- clusion: HELLP syndrome is still one of the most serious and life-threatening complications of pregnancy. Mortality rate can be reduced by regular antenatal follow-up and transfer of pregnant women who carry risk to the intensive care unit without delay.

Incidence of eclampsia with HELLP syndrome and associated mortality in Latin America.

OBJECTIVE: To describe the maternal outcome among women with eclampsia with and without HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count). METHODS: A cross-sectional study of women with eclampsia was undertaken in 14 maternity units in Latin America between January 1 and December 31, 2012. Outcomes were compared between women with and without concomitant HELLP syndrome. Logistic regression analysis was performed to identify independent risk factors of maternal mortality. RESULTS: There were 196 eclampsia cases among 115 038 deliveries; 142 (72.4%) women had eclampsia alone and 54 (27.6%) women had concomitant HELLP syndrome. Severe systolic hypertension (≥160 mm Hg), severe diastolic hypertension (≥110 mm Hg), and hypertensive encephalopathy were significantly more common among women with HELLP than among those with eclampsia alone (P=0.01 for all). There were 8 (4.1%) maternal deaths, all in the group with HELLP syndrome, and 18 (9.1%) perinatal deaths. In a multivariate regression model, maternal mortality was significantly associated with low platelet count and severe systolic hypertension (P<0.05). CONCLUSION: Eclampsia with HELLP syndrome is a dangerous complication associated with pregnancy. Low platelet count secondary to HELLP syndrome and severe systolic hypertension were independently associated with maternal mortality from eclampsia.

[An observation of HELLP syndrome with fatal outcome].

The paper describes the morphopathological changes found at autopsy of a 42-year-old pregnant woman whose death was due to HELLP syndrome (Hemolysis, Elevated Liver enzymes, and Low Platelets) that is rarely encountered in autopsy practice and that is a type of preeclampsia. It considers the morphogenesis of these changes in the light of the pathophysiological mechanisms underlying the syndrome.

Síndrome HELLP: morbilidad-mortalidad materna y perinatal / HELLP syndrome: maternal morbidity and mortality perinatal

Objetivo: Evaluar la morbimortalidad materno fetal y neonatal en pacientes con síndrome HELLP. Métodos: Estudio retrospectivo, descriptivo y longitudinal que fue hecho en 128 pacientes con síndrome HELLP en el período comprendido entre enero 2004 y abril 2009 en el Servicio de Medicina Materno Fetal de la Maternidad “Concepción Palacios”. Resultados: De las 128 pacientes estudiadas, el síndrome HELLP se presentó antes del parto en 85 casos (66,4%) y después del parto en 43 casos (33,6%), el 43,8% de las pacientes fueron primigestas y el 73,4% presentaron el síndrome antes de las 37 semanas. No se presentaron casos de muerte materna. El síndrome se asoció a una alta tasa de morbilidad materna (62,5%) siendo la principal complicación la insuficiencia renal aguda (46%). No hubo ningún caso de hematoma subcapsular hepático. El 100% de las pacientes presentaron algún grado de hipertensión arterial. Hubo una alta tasa de mortalidad perinatal (18%) asociada principalmente a prematuridad. El peso promedio al nacer fue de 1 654 ± 728 g. Conclusión: El síndrome HELLP se asocia a una alta tasa de morbilidad materna extrema y alta tasa de morbimortalidad perinatal, esta última asociada principalmente a complicaciones de prematuridad.

Objective: To evaluate the maternal fetal and neonatal morbidity and mortality in patients with HELLP syndrome. Methods: Retrospective, descriptive and longitudinal study which was developed in 128 patients with HELLP syndrome in the period between January 2004 and April 2009 in the Maternal Fetal Medicine service the Maternity Concepción Palacios. Results: Of the 128 patients studied, the HELLP syndrome was presented before delivery in 85 % cases (66.4 %) and postpartum in 43 cases (33.6 %), 43.8 % of the patients were primiparous and 73.4 % had the syndrome before 37 weeks. No cases of maternal death. Syndrome is associated to a high rate of maternal morbidity (62.5 %) being the main complication of acute renal failure (46 %). There were no cases of hepatic subcapsular hematoma. 100 % of the patients had some degree of arterial hypertension. There was a high perinatal mortality rate (18 %) mainly associated with prematurity. The average birth weight was 1 654 ± 728g. Conclusion: HELLP syndrome is associated with a high rate of near miss maternal morbidity and high rates in perinatal morbidity and mortality, the latter mainly associated with complications of prematurity.

The management of the surgical complications of HELLP syndrome.

INTRODUCTION: Complications from HELLP (Haemolysis, Elevated Liver enzymes and Low Platelet) syndrome may present as an emergency to any surgeon. We review the ten-year experience of a tertiary hepatobiliary centre managing HELLP patients. Three selected cases are described to highlight our management strategy and a systematic review of the recent literature is presented. METHODS: All patients with HELLP syndrome were identified from a prospectively maintained database and their details collated. Subsequently, a detailed search of PubMed was carried out to identify all case series of HELLP syndrome in the literature in the English language since 1999. RESULTS: On review of 1,002 cases, 10 patients were identified with surgical complications of HELLP syndrome. Seven of these patients had a significant liver injury. Only three of these required surgical intervention for liver injury although four other patients required surgical intervention for other complications. There was no maternal mortality in this series. Review of the literature identified 49 cases in 31 publications. The management approaches of these patients were compared with ours. CONCLUSIONS: We have presented a large series of patients with surgical complications resulting from HELLP syndrome managed without maternal mortality. This review has confirmed that haemodynamically stable patients with HELLP syndrome associated hepatic rupture can be conservatively treated successfully. However, in unstable patients, perihepatic packing and transfer to a specialist liver unit is recommended.

Factors contributing to mortality and morbidity in pregnancy-associated intracerebral hemorrhage in Japan.

AIM: The aim of this study was to analyze the causes and outcomes for intracerebral hemorrhage (ICH) occurring during pregnancy and postnatally. MATERIAL AND METHODS: A nationwide study of pregnancy-related ICH in Japan was performed. We contacted 1582 facilities to identify women with ICH in pregnancy or postnatally between 1 January 2006 and 31 December 2006. A total of 1012 facilities (70%) responded with completed questionnaires. Risk factors for ICH, neurological features, onset to diagnosis time (O-D time), and obstetric data were recorded. RESULTS: Thirty-eight cases of pregnancy-associated ICH were identified, corresponding to 3.5 per 100 000 deliveries. There were seven maternal deaths, giving a case mortality rate of 18.4%. Pre-eclampsia was identified in 10 cases (26.3%) and hemolysis elevated liver enzymes and low platelet count (HELLP) syndrome was present in five. There were four cases (10.5%) with Moyamoya disease and seven (18.4%) with arteriovenous malformation. HELLP syndrome and moderately or severely disturbed consciousness at disease onset were significantly associated with a poor outcome (modified Rankin Scale ≥3). Pre-eclampsia, HELLP syndrome and O-D time >3 h were significantly associated with maternal mortality. CONCLUSION: Early diagnosis may prevent maternal death, even in severe cases of pregnancy-related ICH. However, maternal-fetal care centers do not always have full-time neurosurgeons or diagnostic imaging tools suitable for diagnosis of ICH. Thus, a network should be established between maternity centers and neurosurgery departments with computed tomography or magnetic resonance imaging available at all times. We recommend transferal of pregnant women with neurological symptoms to a regional facility that is equipped to treat such patients.

Partial HELLP syndrome: maternal, perinatal, subsequent pregnancy and long-term maternal outcomes.

AIMS: Hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome, in its complete form, is associated with increased risk of maternal mortality and increased rate of serious obstetric complications, such as acute renal failure, hepatic failure, abruptio placentae, pulmonary edema, sepsis, hemorrhage and disseminated intravascular coagulopathy. To compare maternal and perinatal outcomes, we investigated the subsequent pregnancy outcomes and long-term complications of women with partial HELLP (pHELLP) and complete HELLP (cHELLP) syndromes. MATERIAL AND METHODS: In this retrospective study, patients complicated with HELLP between the years 2002 and 2007 were analyzed. cHELLP syndrome was defined by the presence of all of the three laboratory criteria according to the Tennessee Classification System. pHELLP syndrome was defined by the presence of one or two features of HELLP, but not the complete form. RESULTS: Sixty-four patients had cHELLP syndrome and 67 had pHELLP syndrome. Maternal complications and neonatal outcomes of the indexed pregnancies were similar. The rate of blood product transfusion was significantly higher in the cHELLP group (P<0.0001). Twenty-eight patients within the cHELLP group and 26 within the pHELLP group had subsequent pregnancies with a mean interpregnancy interval of 2.9 ± 1.5 years and 2.4 ± 1.1 years, respectively. Elective termination of pregnancy (dilatation and curettage) was more frequent in the cHELLP group. Pre-eclampsia recurrence was higher in the pHELLP group than in the cHELLP group (7.1% vs 34.6%). CONCLUSIONS: Partial and complete HELLP syndrome are not distinct groups based on neonatal, long-term and subsequent pregnancy outcomes. They probably represent a continuum in the natural evolution of the same disease.

Postpartum HELLP syndrome--the case of lost battle.

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.
