Peripheral Anti-Angiogenic Imbalance during Pregnancy Impairs Myogenic Tone and Increases Cerebral Edema in a Rodent Model of HELLP Syndrome. Brain Sci 2018; 8:brainsci8120216. [PMID: 30563221 PMCID: PMC6316026 DOI: 10.3390/brainsci8120216] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 12/04/2018] [Accepted: 12/04/2018] [Indexed: 01/14/2023] Open
Abstract
Using an animal model of hemolysis elevated liver enzymes low platelets (HELLP) that has systemic inflammation and neuroinflammation we wanted to determine if blood brain barrier (BBB) permeability, cerebral edema, vascular tone, and occludin expression were altered in pregnant rats. Anti-angiogenic proteins sFlt-1 and sEng (4.7 and 7 µg/kg/day, respectively) were chronically infused into normal pregnant (NP) rats beginning on gestational day 12 via a mini-osmotic pump. On gestational day 19, blood pressure was measured via a carotid catheter and brains were collected. BBB permeability was assessed in select brain regions from rats infused with 0.5 mg/mL Texas Red Dextran and phenylephrine. Occludin, sFlt-1, and sEng were analyzed via western blot or ELISA. Infusion of sFlt-1 and sEng into NP rats increased hemolysis and liver enzymes, and decreased platelets and led to hypertension. HELLP rats had significant impairment in the myogenic response and increased BBB permeability in the posterior cortex and brainstem. Brain water content in the posterior cortex was increased and sEng protein expression in the brainstem was significantly increased in HELLP rats. The results from this study suggest that a peripheral anti-angiogenic imbalance during pregnancy is associated with decreased myogenic tone, vasogenic edema, and an increase in BBB permeability, but not anti-angiogenic imbalance in the brain.

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
Pre-eclampsia complicates approximately 5-8% of all pregnancies and may have adverse long-term effects on both mother and child. Chronic atraumatic subdural haematoma as a complication of severe pre-eclampsia, in the absence of clotting factor abnormalities, is a very rare condition. We present the case of a 30-year-old Moroccan woman who had a pregnancy 10 years previously, with an uneventful delivery. She presented with pre-eclampsia complicating a 29-week-old pregnancy. A few days preceding maternity unit admission the patient complained of headaches and malaise. Her blood pressure at admission was 150/120mmHg and subsequently was treated with doses of methyldopa and magnesium sulphate. Her condition worsened with a loss of consciousness 24 hours later and was transferred to the neurosurgical unit. A brain computerized tomography (CT) scan revealed a left-sided subdural haematoma and the patient underwent surgery, with a good postoperative outcome. This article highlights the occurrence of neurological complications due to pre-eclampsia/eclampsia that require particular neurosurgical attention, its treatment and prognosis. We also review the literature regarding this pathology.

Abstract
Haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome is a condition associated with increased risk of adverse outcomes during pregnancy and peripartum, including neurological complications. We report the third case in the world literature of delayed brain swelling following cerebral haemorrhage as a complication of HELLP syndrome. A 36-year-old woman in labour developed HELLP, which was complicated with intracerebral haematoma. This was evacuated, but motor impairment persisted after surgery and unfortunately the patient died unexpectedly during the 11th postoperative day. Computer tomographic brain scans documented diffuse cerebral swelling, which we think may have been caused by cerebral vasospasm. Cerebral vasospasm should always be considered when managing patients who suffered from stroke complicating HELLP syndrome. Close monitoring is advised even in later stages of recovery.

Abstract
Hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome is a rare complication of pregnancy. The mortality rate associated with HELLP syndrome increases when life-threatening complications occur. A 37-year-old woman at 37 weeks of gestation developed severe cerebral hemorrhage at the beginning of labor induction and was transferred to our hospital, where HELLP syndrome was diagnosed. She developed disseminated intravascular coagulation (DIC), hepatic hematoma, and cerebral infarction after surgery. On day 68, she was transferred to her local hospital. Careful observation and rapid management can save patients with severe complications of HELLP syndrome.

Abstract
HELLP (haemolysis, elevated liver enzymes, and low platelet count) syndrome can result in a fatal intracranial haemorrhage during the perinatal period. We report treatment of a 32-year-old primigravida who fell into a deep coma during labour with fetal distress, complicated by a spontaneous acute subdural haematoma and intracerebral haemorrhage. Simultaneous emergency operations, evacuation of the acute subdural haematoma and a caesarean section, were performed, during which a diagnosis of HELLP syndrome with disseminated intravascular coagulation was made. Both mother and infant recovered, though hemiparesis persisted in the mother. Patients with HELLP syndrome should be managed as high-risk, which requires an excellent working relationship of the physicians involved. Prompt recognition of intracranial haemorrhagic complications and neurosurgical intervention are particularly important.

Abstract
The HELLP syndrome (haemolysis, elevated liver blood tests and low platelets) 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. Hepatic capsular rupture is a rare yet dramatic complication of HELLP syndrome. The majority of cases occur in multiparous women over the age of 30. Classically it presents with acute onset right upper quadrant pain in the presence of constitutional symptoms such as vomiting and pyrexia. However, symptoms and signs are usually non specific. Spontaneous hepatic rupture can be preceded by signs of hypovolaemic shock; yet the diagnosis is infrequently made prior to emergent laparotomy. We present the case of a 35 year old nulliparous woman with a second trimester gestational hepatic rupture associated with HELLP syndrome. We briefly discuss the aetiology, diagnostic difficulties and treatment options associated with this rare presentation.

Abstract
OBJECTIVE To evaluate maternal deaths associated with eclampsia, HELLP syndrome, and the concurrence of these conditions. METHOD A review of Medline studies reporting maternal deaths associated with eclampsia or HELLP syndrome published in English, Spanish, and Portuguese between 1995 and June 2008. RESULTS A total of 304 deaths were identified: 100 due to eclampsia, 117 due to eclampsia/HELLP, and 87 associated with HELLP syndrome. Of the total deaths, 71.3% of women had seizures and 67.1% developed HELLP syndrome. In high-income countries 3.9% of deaths were due to eclampsia without HELLP syndrome, while in low-income countries this figure was 42.5% (P<0.0001). The presence of HELLP syndrome in the women who died of eclampsia was 90.6% (29/32) in high-income countries compared with 47.6% (88/185) in low-income countries (P<0.001). CONCLUSION Concurrent eclampsia and HELLP syndrome was diagnosed in 5-6 out of 10 deaths associated with eclampsia or HELLP syndrome in this review.

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

Abstract
A 34-year-old grand multipara (para 7, 4 alive) was managed at the National Hospital, Abuja, Nigeria for acute renal failure due to HELLP syndrome following referral from a peripheral hospital. She presented with a history of vomiting, headache, epigastric pain, loss of consciousness and tonic/clonic seizures. Though she was unsure of her exact dates, clinically the gestational age was estimated at 22 weeks. She was managed in the intensive care unit, following delivery of a macerated fetus within 15 h of hospital admission. The patient received mechanical ventilation and three sessions of haemodialysis as part of her successful management while in the intensive care unit. The uncommon presentation of eclampsia and HELLP syndrome before obvious preeclampsia is discussed, as well as the other signs and symptoms and patient management. The case also highlights the resource-poor environment of peripheral and tertiary hospitals in Nigeria.

Abstract
We report a case of a woman with pregnancy-related thrombotic thrombocytopoenic purpura/haemolytic uraemic syndrome (TTP/HUS) who developed cerebral vasospasm similar to that seen in the other pregnancy-related thrombotic microangiopathic syndromes of eclampsia and HELLP syndrome. A further complication in this case was the development of a focal intracerebral haemorrhage necessitating surgical removal. Despite a successful evacuation of the haematoma and several plasma exchange treatments she developed recurrent haemolysis and thrombocytopoenia with an eventual fatal outcome due to severe pulmonary and gastrointestinal haemorrhage.

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