ABSTRACT

OBJECTIVE: Hepatic infarction is a rare complication of pregnancy most often associated with hemolysis, elevated liver enzymes, and low platelets syndrome. The objective of this review is to identify risk factors, present signs and symptoms, identify methods of diagnosis, and identify best management practices on the basis of published case reviews. DATA SOURCES: PubMed and MEDLINE (Ovid) databases were searched for citations regarding hepatic infarction in pregnancy or the postpartum period from database inception until the study date of December 18, 2023. Key words included "liver infarction" or "hepatic infarction" and "pregnancy" or "obstetrics." STUDY ELIGIBILITY CRITERIA: Case reviews or case series published in the English language were included. Our study was registered with the Prospective Register of Systematic Reviews (registration number CRD42023488176) and was conducted in accordance with the published Prospective Register of Systematic Reviews and Meta-analyses Of Observational Studies in Epidemiology guidelines. METHODS: Included papers were evaluated for bias using a previously published tool. RESULTS: A total of 38 citations documenting 50 pregnancies published between 1979 and 2023 were included. Of these, 34% had a history of hypertensive disease, 26% had antiphospholipid syndrome, and 22% had a history of thrombus. Of those without a preexisting diagnosis of antiphospholipid syndrome, 24% tested positive during hospitalization. Most patients presented with epigastric or right upper quadrant pain (78%), and 32% and 16% had severe blood pressure or mild blood pressure, respectively. Sixty-four percent of patients presented with transaminitis. Forty-six percent of patients delivered preterm, and 32% of pregnancies ended in intrauterine fetal demise, abortion, or early termination of pregnancy for maternal benefit. Computed tomography scans were used to confirm diagnosis of hepatic infarction in 58% of cases, magnetic resonance imaging in 14%, and ultrasound in 6%. In cases that described management, treatment was always multimodal, including antihypertensives (18%), therapeutic anticoagulation (45%), blood product transfusion (36%), plasma exchange or intravenous immunoglobulin (20%), and steroids (39%). Transfer to the intensive care unit was required in 20% of cases. CONCLUSION: Hepatic infarction should be considered in all cases of hemolysis, elevated liver enzymes, and low platelets syndrome, but specifically in patients with a history of antiphospholipid syndrome who present with epigastric or right upper quadrant pain. The diagnosis can usually be confirmed with a computed tomography scan alone, and management should be prompt with supportive care, therapeutic anticoagulation, and steroids.

ABSTRACT

BACKGROUND: Obesity increases risk of pre-eclampsia, but the association with haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is understudied. OBJECTIVE: To examine the association between prepregnancy body mass index (BMI) and HELLP syndrome, including early-onset versus late-onset disease. STUDY DESIGN: A retrospective cohort study using population-based data. SETTING: British Columbia, Canada, 2008/2009-2019/2020. POPULATION: All pregnancies resulting in live births or stillbirths at ≥20 weeks' gestation. METHODS: BMI categories (kg/m2) included underweight (<18.5), normal (18.5-24.9), overweight (25.0-29.9) and obese (≥30.0). Rates of early-onset and late-onset HELLP syndrome (<34 vs ≥34 weeks, respectively) were calculated per 1000 ongoing pregnancies at 20 and 34 weeks' gestation, respectively. Cox regression was used to assess the associations between risk factors (eg, BMI, maternal age and parity) and early-onset versus late-onset HELLP syndrome. MAIN OUTCOME MEASURES: Early-onset and late-onset HELLP syndrome. RESULTS: The rates of HELLP syndrome per 1000 women were 2.8 overall (1116 cases among 391 941 women), and 1.9, 2.5, 3.2 and 4.0 in underweight, normal BMI, overweight and obese categories, respectively. Overall, gestational age-specific rates of HELLP syndrome increased with prepregnancy BMI. Obesity (compared with normal BMI) was more strongly associated with early-onset HELLP syndrome (adjusted HR (AHR) 2.24 (95% CI 1.65 to 3.04) than with late-onset HELLP syndrome (AHR 1.48, 95% CI 1.23 to 1.80) (p value for interaction 0.025). Chronic hypertension, multiple gestation, bleeding (<20 weeks' gestation and antepartum) also showed differing AHRs between early-onset versus late-onset HELLP syndrome. CONCLUSIONS: Prepregnancy BMI is positively associated with HELLP syndrome and the association is stronger with early-onset HELLP syndrome. Associations with early-onset and late-onset HELLP syndrome differed for some risk factors, suggesting possible differences in aetiological mechanisms.

ABSTRACT

Critical bleeding is a common cause of maternal mortality in obstetric patients. However, the non-obstetric factors underlying critical obstetric bleeding remain uncertain. Therefore, this study aimed to clarify the impact of chronic hypertension on obstetric hemorrhage by evaluating a nationwide administrative database in Japan. Women who gave birth between 2018 and 2022 were enrolled. The primary outcome was critical hemorrhage requiring massive red blood cell (RBC) transfusion during childbirth. In total, 354, 299 eligible women were selected from the database. The maternal mortality rate was >1.0% among those who received a massive RBC transfusion (≥4000 cc), and this amount was used as the cutoff of the outcome. Critical hemorrhage was less frequent with elective Caesarean section (CS) compared with vaginal childbirth or emergent CS (odds ratio [OR], 0.38; 95% confidence interval, 0.30-0.47). Multiple logistic regression analysis adjusting for these obstetric risks revealed that a higher maternal age (adjusted OR [aOR] per 1 year, 1.07 [1.05-1.09]); oral medications with prednisolone (aOR, 2.5 [1.4-4.4]), anti-coagulants (aOR, 10 [5.4-19]), and anti-platelets (aOR, 2.9 [1.3-6.4]); and a prenatal history of hypertension (aOR, 2.5 [1.5-4.4]) and hypoproteinemia (aOR, 5.8 [1.7-20]) are the risks underlying critical obstetric hemorrhage. Prenatal history of hypertension was significantly associated with obstetric disseminated intravascular coagulation (OR, 1.9 [1.5-2.4]); Hemolysis, Elevated Liver enzymes, and Low platelet count (HELLP) syndrome (OR, 3.3 [2.7-4.2]); and eclampsia (OR, 6.1 [4.6-8.1]). In conclusion, a maternal prenatal history of hypertension is associated with the development of HELLP syndrome, eclampsia, and resultant critical hemorrhage. The incidence of HELLP syndrome and eclampsia increased more than fivefold in the presence of prenatal hypertension. However, the likelihood of subsequently developing DIC or experiencing critical bleeding did not change by the presence of prenatal hypertension.

ABSTRACT

BACKGROUND: HELLP syndrome refers to a group of clinical syndromes characterized by hemolysis, elevated liver enzymes and low platelet, and the evidence on the association between proteinuria and the severity of HELLP and its maternal and neonatal outcomes is rare. METHODS: 106 pregnant women were assigned to the proteinuric group (24-hUPro ≥ 0.3 g, 79 cases) and the non-proteinuric group (24-hUPro < 0.3 g, 27 cases). The proteinuric group was further divided into three subgroups: mild group (24-hUPro:0.3-2.0 g, 33 cases), moderate group (24-hUPro:2.0-5.0 g, 21 cases) and severe group (24-hUPro: ≥5.0 g, 25 cases). The general clinical data, laboratory indexes, complications and pregnancy outcome and adverse neonatal outcomes of HELLP with or without proteinuric were analyzed. RESULTS: Compared with proteinuric group, the non-albuminuric group or in the three proteinuric subgroups of HELLP pregnant women's, increased proteinuria was associated with earlier onset gestations, higher incidence of abdominal pain, skin jaundice, headache, blurred vision (p < 0.05 respectively), and also the higher levels of ALT, AST, LDH, Fib, APTT, ATII, proportions of tubular urine and lower levels of ALB, PLT (p < 0.05 respectively). In the three subgroups of the proteinuric group, the ratio of fetal growth restriction, cesarean section and postpartum hemorrhage were compared, and the difference was statistically significant (p < 0.05 respectively). Compared with the proteinuric group, the non-proteinuric group had higher birth weight, birth length, and lower SGA, admission rate in NICU (p < 0.05 respectively). In the three subgroups of the proteinuric group, significant differences were identified in the adverse outcomes of newborns (p < 0.05 respectively), and the incidence of adverse outcomes in neonates tended to be higher. Significant differences were identified in birth weight, birth length, and lower SGA and NICU occupancy rate among the three subgroups (p < 0.05 respectively). CONCLUSIONS: HELLP syndrome is a severe complication of pregnancy, involving multiple systems of the whole body. It has posed a great challenge to obstetricians for its acute onset, dangerous condition, rapid progress, and great harm. Thus, insights into HELLP syndrome should be gained, and early diagnosis, early treatment and timely termination of pregnancy should be conducted to reduce the incidence of maternal and fetal adverse outcomes and improve maternal and fetal prognosis.

ABSTRACT

OBJECTIVE: To study the maternal and perinatal outcomes in women with severe pre-eclampsia before 28 weeks of pregnancy. METHODS: A descriptive study from a tertiary care center. All consecutive women with severe pre-eclampsia withonset before 28 weeks of pregnancy were included. The details were collected in a predesigned structured proforma prospectively. RESULTS: The study cohort included 145 women with a mean maternal age of 26.97 ± 5.36 years (range 19-47 years). The mean duration of prolongation of pregnancy was 13.04 ± 10.57 days (range 1-51 days). A total of 29.7% (n = 43) of women had at least one major adverse maternal outcome, and the most common was HELLP (hemolysis, elevated liver enzymes, low platelet count) syndrome (n = 24,16.6%), followed by eclampsia (n = 12,8.3%). The stillbirth rate was high (n = 103,68.7%), and most occurred in the antepartum period. Of 47 (31.3%) neonates born alive, only eight (17.02%;8/47) survived up to 28 days of life. Fetal growth restriction with Doppler abnormalities and neonatal sepsis were the most common reasons for perinatal mortality. CONCLUSION: Expectant management should not be considered routinely when the onset of severe pre-eclampsia is before 25+6 weeks of pregnancy. Between 26 and 27+6 weeks it can be offered under close monitoring and the perinatal survival depends on the neonatal services available in their facility.

ABSTRACT

Objective: To analyze the clinical features and pregnancy outcomes in antepartum and postpartum hemolysis, elevated live enzymes, and low platelet count syndrome(HELLP syndrome). Methods: A retrospective study was conducted to collect maternal and neonatal information of pre-eclampsia complicated with HELLP syndrome in Peking University First Hospital during the ten years from April 2009 to March 2019. A total of 83 pregnant women were included according to the Tennessee Classification System. They were then allocated into two groups based on the onset time of HELLP syndrome: antepartum HELLP syndrome group (n=70) and postpartum HELLP syndrome group (n=13). The clinical features, symptoms, laboratory biomarkers, and pregnancy outcomes were compared between the two groups. Results: Among the 83 pregnant women with HELLP syndrome, 70 occurred prenatally (84%, 70/83) and 13 occurred postpartum (16%, 13/83). The twin or triplet pregnancy rate in the postpartum HELLP syndrome group was significantly higher than that in the antepartum HELLP syndrome group [6/13 vs 6% (4/70), P=0.001]. The gestational weeks for HELLP onset and delivery in the postpartum HELLP syndrome group were significantly later than those in the antepartum HELLP syndrome group [(35.8±3.0) vs (31.5±5.2) weeks, P=0.025; (36.7±2.3) vs (32.2±5.0) weeks, P=0.002]. The incidence of early-onset pre-eclampsia in the antepartum HELLP syndrome group was significant higher than that in the postpartum HELLP syndrome group [64% (45/70) vs 2/13, P=0.002]. The quantitative of 24-hour proteinuria was significant higher in the antepartum HELLP syndrome group than that in the postpartum HELLP syndrome group [(4.8±5.1) vs (1.8±1.6) g, P=0.002]. But there were no statistical significances in the comparison of other laboratory test indexes (all P>0.05). There were no significant differences between the two groups in clinical symptoms, severe maternal complications, transfusion or adverse maternal outcomes (all P>0.05). Conclusions: Antepartum and postpartum HELLP syndrome have similar clinical symptoms and laboratory characteristics. Both antepartum and postpartum HELLP syndrome could lead to severe maternal complications, which should be paid special attention in clinical practice, especially to the postpartum HELLP syndrome.

ABSTRACT

BACKGROUND: Cervical artery dissection (CeAD) is responsible of one fifth of cases of ischemic stroke, but is uncommon during pregnancy or the early postpartum period and evidence is derived from published case reports and case series. OBJECTIVES: This systematic review with a prospectively registered protocol was conducted to study the clinical presentation, management and prognosis of this condition. METHODS: Ovid-Medline, PubMed Central, and CINAHL were searched without language restriction. RESULTS: Fifty-seven articles (50 case reports and seven case series) reporting on 77 patients were included. The mean age was 33.7 years. The main possible risk factors identified were migraine, hyperlipidemia, connective tissue disorders, preeclampsia and eclampsia, HELLP syndrome and prolonged second stage of labor. Headache was the most frequent symptom, followed by neck pain. Acute medical treatments included anticoagulation, antiplatelets, and endovascular therapy. No patients received thrombolysis. The overall prognosis was good with 77.8% of patients making full clinical recovery. CONCLUSIONS: Cervical artery dissection is a rare, but an important complication of pregnancy and puerperium. Diagnosis requires a high index of suspicion. The strong association with hypertensive and connective tissue disorders requires further research.

ABSTRACT

Intracranial haemorrhage (ICH) is an uncommon but one of the most devastating and potentially fatal complications of preeclampsia. Most ICHs in pregnancy are reported in the absence of a vascular lesion, and severe systolic hypertension is thought to be an important risk factor even though many reports suggest that ICH can complicate preeclampsia even at lower blood pressure levels. In this case-control study of preeclamptic women, risk factors associated with ICH were compared in women who did and did not develop ICH. During the study period, ICH occurred in 1.8% (42/2167) pregnancies with preeclampsia, with 45.2% (n = 19/42) resulting in maternal mortality. HELLP syndrome (OR = 11.5; 95% CI 3.8-34.8), multiparity (OR 3.2; 95% CI 1.4-7.7), nausea/vomiting (OR = 3.6; 95% CI 1.4-9.3), and lower educational attainment (OR = 38.2; 95% CI 3.5-423.6) were associated with the increased probability of ICH. The incidence of caesarean birth (n = 29, 74.4% vs. n = 161, 34.5%) and neonatal mortality (n = 4, 13.3% vs. n = 17, 4.0%) were higher among preeclamptic who have ICH compared to those who did not have it. Improving awareness as well as early identification of those at risk of preeclampsia and complications can limit the impact of ICH among pregnant women with preeclampsia, especially in low- to middle-income countries.

ABSTRACT

OBJECTIVE: Significant changes to the delivery of obstetrical care that occurred with the onset of the COVID-19 pandemic may be associated with higher risks of adverse maternal outcomes. We evaluated preeclampsia/HELLP (hemolysis, elevated liver enzymes and low platelets) syndrome and composite severe maternal morbidity (SMM) among pregnant people who gave birth during the COVID-19 pandemic and compared these data with those of people who gave birth before the pandemic in Ontario, Canada. METHODS: This was a population-based, retrospective cohort study using linked administrative data sets from ICES. Data on pregnant people at ≥20 weeks gestation who gave birth between March 15, 2020, and September 30, 2021, were compared with those of pregnant people who gave birth within the same date range for the years 2015-2019. We used multivariable logistic regression to assess the effect of the pandemic period on the odds of preeclampsia/HELLP syndrome and composite SMM, adjusting for maternal baseline characteristics and comorbidities. RESULTS: There were no differences between the study periods in the adjusted odds ratios (aORs) for preeclampsia/HELLP syndrome among primiparous (aOR 1.00; 95% CI 0.91-1.11) and multiparous (aOR 0.94; 95% CI 0.81-1.09) patients and no differences for composite SMM (primiparous, aOR 1.00; 95% CI 0.95-1.05; multiparous, aOR 1.01; 95% CI 0.95-1.08). CONCLUSION: Adverse maternal outcomes were not higher among pregnant people who gave birth during the first 18 months of the COVID-19 pandemic in Ontario, Canada, when compared with those who gave birth before the pandemic.

ABSTRACT

OBJECTIVE: To review literature and estimate the occurrence of preeclampsia and its complications in Brazil. METHODS: We performed an integrative review of the literature, and included observational studies published until August 2021 on the SciELO and PubMed databases that evaluated preeclampsia among pregnant women in Brazil. Other variables of interests were maternal death, neonatal death, hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and eclampsia. Three independent reviewers evaluated all retrieved studies and selected those that met inclusion criteria. A metanalysis of the prevalence of preeclampsia and eclampsia was also performed, to estimate a pooled frequency of those conditions among the studies included. RESULTS: We retrieved 304 studies after the initial search; of those, 10 were included in the final analysis, with a total of 52,986 women considered. The pooled prevalence of preeclampsia was of 6.7%, with a total of 2,988 cases reported. The frequency of eclampsia ranged from 1.7% to 6.2%, while the occurrence of HELLP syndrome was underreported. Prematurity associated to hypertensive disorders ranged from 0.5% to 1.72%. CONCLUSION: The frequency of preeclampsia was similar to that reported in other international studies, and it is increasing in Brazil, probably due to the adoption of new diagnostic criteria. The development of a national surveillance network would be essential to understand the problem of hypertensive disorders of pregnancy in Brazil.


OBJETIVO: Revisar a literatura e estimar a ocorrência de pré-eclâmpsia e suas complicações no Brasil. MéTODOS: Foi realizada uma revisão integrativa da literatura, com a inclusão de estudos observacionais publicados até agosto de 2021, nas bases de dados PubMed e SciELO, que avaliavam pré-eclâmpsia em mulheres brasileiras. Outras variáveis de interesse foram morte materna, morte neonatal, síndrome de hemólise, enzimas hepáticas elevadas e plaquetopenia (hemolysis, elevated liver enzymes, and low platelet count, HELLP, em inglês) e eclâmpsia. Três revisores independentes avaliaram os estudos identificados e selecionaram aqueles que preenchiam os critérios de inclusão. Foi realizada uma meta-análise da prevalência de pré-eclâmpsia e eclâmpsia, para estimar sua frequência acumulada com relação aos estudos incluídos. RESULTADOS: Foram identificados 304 estudos, 10 dos quais foram incluídos na análise final, num total de 52.986 mulheres. A frequência acumulada de pré-eclâmpsia foi de 6,7%, com um total de 2.988 casos. A frequência de eclâmpsia variou de 1,7% a 6,2%, ao passo que a ocorrência de síndrome de HELLP foi pouco relatada. A prematuridade associada a hipertensão foi de 0,5% a 1,7%. CONCLUSãO: A frequência de pré-eclâmpsia foi similar à de estudos internacionais; no entanto, ao longo dos últimos anos, ela vem aumentando no Brasil, possivelmente como reflexo da adoção de novos critérios diagnósticos. A criação de uma rede nacional de vigilância seria fundamental para entender o problema da hipertensão na gestação no país.

ABSTRACT

BACKGROUND: Many providers ignore hypertensive blood pressures (BPs) during epidural placement, attributing them to patient pain or malposition. We aimed to determine if an elevated BP during epidural placement was associated with increased risk for developing a hypertensive disorder of pregnancy (HDP). METHODS: Cohort study of previously normotensive nulliparous, singleton, term patients who received neuraxial analgesia and delivered at our institution in 2016. Primary exposure was BP during epidural window (one hour before and after epidural procedure start time). Primary outcome was HDP (gestational hypertension, preeclampsia, eclampsia, or HELLP syndrome) prior to discharge. Statistics included χ2, t-test, and multivariable logistic regression; α = 0.05. RESULTS: One thousand and eight hundred patients met study criteria. Patients with elevated BP during epidural window (n = 566, 31.4%) were more likely to develop HDP than patients who remained normotensive during epidural window (20.1% vs. 6.4%, adjusted OR 3.57 [95% CI 2.61-4.89]). The incidence of HDP increased in association with BP severity during epidural window: 7.3% for maximum systolic blood pressure (SBP) <140 mmHg; 18.4% for maximum SBP 140-159 mmHg (OR 2.9, 95% CI 2.0-4.0); and 29.9% for maximum SBP ≥160 mmHg (OR 5.4, 95% CI 2.9-9.8). The trend was similar for maximum diastolic BP. The magnitude of increased odds for HDP was highest for Black patients with elevated BP during epidural window (40.9% vs. 10.1%, OR 6.1, 95% CI 2.4-16). CONCLUSIONS: Previously normotensive patients with an elevated BP during labor epidural placement are significantly more likely to develop HDP than patients who remain normotensive. Elevated BP during epidural placement should not be disregarded to ensure timely diagnosis and treatment.

ABSTRACT

OBJECTIVES: Excessive left ventricular mass (LVM) results in inefficient LV work with energy waste leading to a negative prognostic effect. We aimed at investigating the presence of inappropriate LVM and calculating the myocardial mechano-energetic efficiency index (MEEi) in former pre-eclamptic (PE) women (with or without HELLP syndrome) compared to women who experienced HELLP syndrome without PE. STUDY DESIGN: In this cross-sectional study, women with a history of normotensive HELLP (n = 32), PE without HELLP (n = 59), and PE with HELLP (n = 101) underwent echocardiography as part of the clinical CV work-up after their complicated pregnancies from 6 months to 4 years postpartum. We excluded women with comorbidities, including chronic hypertension, hypercholesterolemia, and obesity. MAIN OUTCOME MEASURES: LVM excess was calculated as the ratio between observed LVM and predicted LVM (by sex, stroke work and height), while MEEi was considered as the ratio between stroke work and "double product" (to approximate energy consumption), indexed to LVM. RESULTS: LV hypertrophy was present in 8-14% and concentric remodeling in 31-42% of women, without intergroup difference. LVM was inappropriate in one-third of normotensive former HELLP and in about one-half of PE with or without HELLP, with no difference among groups. Accordingly, without nominal difference, MEEi showed a tendency towards lower values in former pre-eclamptic individuals. CONCLUSIONS: Women with a history of HELLP syndrome, independently from the presence/absence of PE, showed inappropriate LVM in the first 4 years after delivery, which may partially explain the elevated CV risk in these women compared to the general female population.

ABSTRACT

OBJECTIVE: To compare maternal and perinatal outcomes between randomized trials and observational studies in which conservative management was performed for more than 48 h in patients with early-onset severe preeclampsia. METHODOLOGY: We searched PubMed, LILACS, Cochrane and Google Scholar. The studies were divided in two groups: randomized and observational studies, from 1990 to 2018 that included patients with severe preeclampsia before 34 weeks of gestation with pregnancy prolongation ≥48 h but that did not include fetal growth restriction or HELLP syndrome at the beginning. The main variables recorded were maternal and perinatal complications. MAIN RESULTS: Forty-four studies met the inclusion criteria, and 5 of these were randomized. The average pregnancy prolongation was 9 days, with no difference between groups. Maternal complications were significantly more common in observational studies, RR = 0.71, 95% CI (0.54-0.93), p = .009. Perinatal complications were also significantly more common in observational studies (RR = 0.89, 95% CI (0.80-0.98), p = .01) at the expense of stillbirth and neonatal deaths. The percentages of cesarean sections were significantly higher in randomized studies, RR = 1.54, 95% CI (1.46-1.64). There were 2 maternal deaths, both in observational studies. CONCLUSION: Observational studies in which conservative management of early-onset preeclampsia is performed and do not include patients with fetal growth restriction or patients with HELLP syndrome and where at least 2 days of pregnancy prolongation is achieved are associated with significantly more maternal and perinatal complications.

ABSTRACT

PURPOSE: Hypertensive disorders of pregnancy are still a leading cause of maternal and neonatal morbidity and mortality worldwide. Women with a history of preeclampsia have an increased risk for future cardiovascular and cerebrovascular disease, renal disease as well as diabetes mellitus. There is little knowledge on postpartum risk management. The aim of this study was to assess follow-up care for patients after pre-eclampsia or HELLP syndrome. METHODS: This questionnaire-based cross-sectional study aimed to evaluate the current recommendations of obstetricians in Austria regarding follow-up care, long-term risk counselling and risk of recurrence in future pregnancies after preeclampsia or HELLP syndrome. Data were collected using a survey, based on recommendations given by three substantial guidelines on hypertensive disorders of pregnancy, which was distributed via e-mail to 69 public obstetric departments in Austria. Each obstetric department was required to answer one questionnaire per local protocol. RESULTS: Our results revealed that of the 48 participating hospitals most obstetricians are aware of the importance of follow-up care for women after a pregnancy complicated by preeclampsia. Our data show that most physicians counselled patients about the future cardiovascular health risks associated with preeclampsia or HELLP syndrome (79.2%). Most obstetricians recommended lifestyle modification (77.1%) and continued blood pressure measurements (97.9%). All centers stated to counsel about the risk of recurrence (100%). However, counselling regarding follow-up care to exclude kidney damage (37.5%) and underlying diseases like thrombophilia (39.6%) were less prioritized. CONCLUSIONS: We were able to show that counselling concerning the risk of long-term cardiovascular disease and risk of recurrence after a pregnancy complicated by preeclampsia or HELLP syndrome has been established in obstetric departments in public hospitals. Regarding the evaluation of underlying chronic diseases such as thrombophilia or renal disease, as well as counselling on the future risk of renal disease is still improvable according to our data. Further evaluation of follow-up care after hypertensive disorders of pregnancy in the outpatient and private sector and implementation of structured guidelines for follow-up, as well as screening for cardiovascular disease are necessary to ensure adequate risk management and to provide opportunities for prevention.

ABSTRACT

Purpose: HELLP syndrome is a relatively uncommon pregnancy-related condition characterized by hemolysis, elevated liver function tests, and low platelets. It can be accompanied by life-threatening hepatic complications including hepatic infarction, hematoma formation, and hepatic rupture. HELLP syndrome occurs in approximately 0.2% of pregnancies. Major hepatic complications occur in less than 1% of HELLP patients suggesting an incidence of 1/50,000. The pathogenesis is incompletely understood and in particular, it is difficult to understand a disorder with both major thrombotic and bleeding manifestations.Methods: Literature review.Results: On the basis of reports in the published literature, and our own clinical experience, we suggest that vasospasm is one of the principal drivers with hepatic ischemia, infarction, and hemorrhage as secondary events. It is known that vasoactive substances are released by the failing placenta. We suggest these cause severe vasospasm, most likely affecting the small post-sinusoidal hepatic venules. This leads to patchy or confluent hepatic ischemia and/or necrosis with a resultant increase in circulating liver enzymes. Reperfusion is associated with a fall in platelet count and microvascular hemorrhage if the microvasculature is infarcted. Blood tracks to the subcapsular space causing hematoma formation. If the hematoma ruptures the patient presents with severe abdominal pain, intra-abdominal hemorrhage, and shock.Conclusions: We suggest that hepatic and other complications associated with HELLP syndrome including placental abruption, acute renal failure, and posterior reversible encephalopathy syndrome (PRES) may also be due to regional vasospasm.

ABSTRACT

OBJECTIVES: To evaluate how medical comorbidities - chronic hypertension, pre-gestational or gestational diabetes and obesity - influence maternal and neonatal complications from preeclampsia. STUDY DESIGN: We undertook a retrospective cohort study of women delivering in Victoria, Australia, between 2009 and 2017. We compared the likelihood of having a maternal complication before delivery or neonatal complication after birth between women with and without comorbidities. We used causal mediation analysis for neonatal outcomes to separate the effects of comorbidities and of prematurity on morbidity. MAIN OUTCOME MEASURES: Pregnancy complications (eclampsia; haemolysis, elevated liver enzymes, low platelets syndrome; placental abruption; stillbirth) and neonatal complications (respiratory distress syndrome; neonatal sepsis; a 5-minute APGAR < 5; neonatal intensive care unit admission). RESULTS: Women with comorbidities delivered at a median (interquartile range) of 37.0 (36.0-39.0) weeks gestation, earlier than women without comorbidities (38.0 (36.0-39.0) weeks, p < 0.001). Women with comorbidities were less likely than those without to suffer any pregnancy complication prior to delivery (adjusted relative risk 0.78, 95% confidence interval 0.72-0.86); however, their neonates suffered more respiratory distress syndrome (aRR 1.43, 95% CI 1.31-1.57), neonatal sepsis (aRR 1.42, 95% CI 1.17-1.72) and NICU admission (aRR 1.37, 95% CI 1.23-1.53). Earlier delivery was a major contributor to worse neonatal outcomes. CONCLUSIONS: Medical comorbidities are associated with earlier delivery among women with preeclampsia. This is associated with fewer maternal complications, but worse neonatal outcomes.

ABSTRACT

OBJECTIVES: This meta-analysis aimed to evaluate the effectiveness of HCQ in improving the maternal and fetal outcomes in pregnancies with SLE. METHODS: A literature search was conducted using PubMed, MEDLINE, EMBASE, and the Cochrane database for relevant English language articles, and Wanfang, CNKI and VIP for Chinese articles, from the databases' inception to April 30, 2020. These studies compared the maternal and/or fetal outcomes between pregnant patients with SLE who were administered HCQ during pregnancy (HCQ+ group) and those who were not administered HCQ (HCQ- group). Two investigators extracted the data and assessed the quality using the Newcastle-Ottawa Scale (NOS) and GRADE criteria independently. Odds ratio (OR) and 95% confidence intervals (CIs) were calculated. All statistical analyses were conducted using the Stata 12.0 software. RESULTS: Nine studies involving 1132 pregnancies were included in the study (3 case controls, 2 prospective cohorts, 4 retrospective cohorts). Preeclampsia, gestational hypertension, and prematurity were significantly lower in the HCQ+ group than in the HCQ- group (OR 0.35, 95% CI 0.21-0.59), (OR 0.41, 95% CI 0.19-0.89) and (OR 0.55, 95% CI 0.36-0.86), respectively. There were no significant differences in the rates of HELLP Syndrome (OR 0.88, 95% CI 0.19-3.96), gestational diabetes (OR 2.3, 95% CI 0.44-12.12), thrombotic events (OR 0.26, 95% CI 0.05-1.51), spontaneous abortion (OR 1.77, 95% CI 0.96-3.26), premature rupture of membranes (OR 0.58, 95% CI 0.24-1.39), oligohydramnios (OR 0.90, 95% CI 0.38-2.14), live birth (OR 1.22, 95% CI 0.60-2.47), stillbirth (OR 1.00, 95% CI 0.50-2.00), congenital malformation (OR 0.53, 95% CI 0.14-2.04), low birth weight (OR 0.77, 95% CI 0.43-1.39), intrauterine distress (OR 1.07, 95% CI 0.41-2.76,), intrauterine growth restriction (OR 0.57, 95% CI 0.06-5.43), or five-minute APGAR score <7 (OR 0.72, 95% CI 0.20-2.58) between the two groups. CONCLUSIONS: HCQ treatment during pregnancy could reduce the risk of preeclampsia, pregnancy hypertension and prematurity in SLE patients. The certainty of evidence is high but majority of the studies included are retrospective studies and not randomized controlled trials. Therefore, the multidisciplinary management of pregnant patients with SLE should promote HCQ use, irrespective of disease activity or severity.

ABSTRACT

The clinical spectrum of hypertensive disorders of pregnancy (HDP) is determined by the interplay between environmental and genetic factors, most of which remains unknown. ERAP1, ERAP2 and LNPEP genes code for multifunctional aminopeptidases involved with antigen processing and degradation of small peptides such as angiotensin II (Ang II), vasopressin and oxytocin. We aimed to test for associations between genetic variants in aminopeptidases and HDP. A total of 1282 pregnant women (normotensive controls, n = 693; preeclampsia, n = 342; chronic hypertension with superimposed preeclampsia, n = 61; eclampsia, n = 74; and HELLP syndrome, n = 112) were genotyped for variants in LNPEP (rs27300, rs38034, rs2303138), ERAP1 (rs27044, rs30187) and ERAP2 (rs2549796 rs2927609 rs11135484). We also evaluated the effect of ERAP1 rs30187 on plasma Ang II levels in an additional cohort of 65 pregnant women. The genotype C/C, in ERAP1 rs30187 variant (c.1583 T > C, p.Lys528Arg), was associated with increased risk of eclampsia (OR = 1.85, p = 0.019) whereas ERAP2 haplotype rs2549796(C)-rs2927609(C)-rs11135484(G) was associated with preeclampsia (OR = 1.96, corrected p-value = 0.01). Ang II plasma levels did not differ across rs30187 genotypic groups (p = 0.895). In conclusion, ERAP1 gene is associated with eclampsia whereas ERAP2 is associated with preeclampsia, although the mechanism by which genetic variants in ERAPs influence the risk of preeclampsia and eclampsia remain to be elucidated.

ABSTRACT

OBJECTIVES: The purpose of this study was to identify the number of pregnancies affected by hypertension in Ireland and report on possible risk factors and adverse pregnancy outcomes for women and their babies. STUDY DESIGN: Data on maternity hospital discharges for women giving birth in Ireland in 2016 were extracted from the national Hospital In-Patient Enquiry data system. Women with a diagnosis of a hypertensive disorder of pregnancy were identified using relevant ICD codes. Descriptive statistics were used to present prevalence, and Pearson's Chi-square and multivariable regression analyses were conducted to identify risk factors and pregnancy outcomes. Differences between proportions were analysed by Pearson's Chi-squared test of independence. RESULTS: Of 60,188 maternities reported for the year 2016, 5.9% of women (n = 3531) had a hypertensive disorder of pregnancy and 4.6% (n = 2790) had pre-eclampsia. Rates were higher among women with pre-existing diabetes, gestational diabetes, obesity and those aged ≥40 years. After adjusting for maternal age, pre-existing DM, GDM, obesity and tobacco use, obesity (AOR 4.3; 95% CI: 3.2-5.7; p < 0.001), pre-existing diabetes (AOR 3.5; 95% CI: 2.5-4-9; p < 0.001), gestational diabetes (AOR 1.5; 95% CI: 1.3-1.8; p < 0.001) and being aged ≥40 years (AOR 1.5; 95% CI: 1.3-1.7; p < 0.001) remained significantly associated with being diagnosed with a hypertensive disorder of pregnancy in the Republic of Ireland. CONCLUSION: In Ireland where maternal age at childbirth is increasing, the association of hypertension with advancing age will undoubtedly contribute to a greater prevalence of hypertensive disorders of pregnancy and their potential adverse outcomes for pregnant women and their babies. This retrospective study highlights the prevalence rates in Ireland while also identifying possible risk factors and associated adverse pregnancy outcomes. They pinpoint the need for further research to look in more detail at risk factors and adverse outcomes for the 79% (n = 2790) of women presenting with pre-eclampsia among this large nationally representative sample of women.

ABSTRACT

Preeclampsia is a multisystemic disorder which accounts for the high prevalence of maternal and perinatal morbidity and mortality, especially in middle and low-income countries. Currently, the primary intervention is the urgent delivery of the fetus, hence it would be advantageous to identify those who are likely to develop preeclampsia and the maternal and fetal outcomes. However, an array of risk factors makes these challenging. This review explores the potentials of liver biomarkers in predicting the occurrence and outcome of preeclampsia, which could be beneficial in reducing the burden of the disease. Liver dysfunction in preeclampsia results in a severe condition, hence liver function tests are specific predictors of outcome.
