Cerebral Vein Thrombosis in the Antiphospholipid Syndrome: Analysis of a Series of 27 Patients and Review of the Literature. Brain Sci 2021; 11:brainsci11121641. [PMID: 34942943 PMCID: PMC8699363 DOI: 10.3390/brainsci11121641] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 12/05/2021] [Accepted: 12/06/2021] [Indexed: 02/02/2023] Open
Abstract
(1) Background: The Antiphospholipid Syndrome (APS) is a systemic autoimmune disorder characterized by arterial and/or venous thrombosis, pregnancy morbidity and raised titers of antiphospholipid antibodies. Cerebral vein thrombosis (CVT) is a rare form of cerebrovascular accident and an uncommon APS manifestation; the information in the literature about this feature consists of case reports and small case series. Our purpose is to describe the particular characteristics of CVT when occurs as part of the APS and compare our series with the patients published in the literature. (2) Methods: We conducted a retrospective observational study collecting data from medical records in three referral centers for APS and CVT, and a systematic review of the literature for CVT cases in APS patients. (3) Results: Twenty-seven APS patients with CVT were identified in our medical records, the majority of them diagnosed as primary APS and with the CVT being the first manifestation of the disease; additional risk factors for thrombosis were identified. The review of the literature yielded 86 cases, with similar characteristics as those of our retrospective series. (4) Conclusions: To our knowledge, our study is the largest CVT series in APS patients published to date, providing a unique point of view in this rare thrombotic manifestation.

Abstract
Antiphospholipid syndrome (APS) with cerebral venous sinus thrombosis (CVST) is a relatively rare phenomenon, and this observational study aimed to investigate the clinical characteristics of APS patients complicated with CVST. We retrospectively investigated the clinical characteristics of CVST events in APS and compared differential characteristics and associated factors between APS patients with and without CVST. Twenty-one CVST patients with APS were enrolled including 14 females (9.4%) and 7 males (5.8%). The median age and disease duration at onset of CVST was 33 years (IQR 28-48) old and 1.3 months (IQR 0.7-4), respectively. Among APS patients with CVST, 12 (57.1%) cases presented with neurologic symptoms of CVST as the initial manifestation. Onset of CVST was mainly chronic (52.4%). Headache (90.5%) was the most common neurological symptom. The common locations of CVST were transverse sinus (76.2%) and superior sagittal sinus (57.1%), with more frequently (76.2%) dual or multiple sinuses involved. All patients with CVST were treated with anticoagulant, and 5 (23.8%) patients received endovascular therapy. Sixteen (84.2%) patients had good outcomes and 3 (15.8%) patients died at last follow-up. There were no significant differences (P > 0.05) between two groups in the analysis of related APS indicators. There were no significant differences (P > 0.05) between two groups in the analysis of related APS indicators. Although APS complicated with CVST is rare and predominately chronic developed. The evaluation of CVST should be performed for APS patients with intracranial hypertension syndrome. The routine screening of antiphospholipid antibodies (aPLs) is highly recommended in unexplained CVST patients. Most CVST patients with APS will have a good prognosis after treatment, and endovascular therapy is an alternative treatment.

Abstract
Antiphospholipid syndrome (APS) or Hughes syndrome is an acquired thromboinflammatory disorder. Clinical criteria of APS diagnosis are large- and small-vessel thrombosis as well as obstetric problems; laboratory criteria are the presence of antiphospholipid antibodies (lupus anticoagulant, anticardiolipin antibodies and anti-β2-glycoprotein-1). The presence of at least 1 clinical and 1 laboratory criterion allows definitive diagnosis of APS. Primary APS is diagnosed in patients without features of connective tissue disease; secondary APS is diagnosed in patients with clinical signs of autoimmune disease. A high frequency of catastrophic APS as well as a high tendency to evolve from primary APS to secondary syndrome during the course of lupus and lupus-like disease is a feature of pediatric APS. The most characteristic clinical presentation of APS in the pediatric population is venous thrombosis, mainly in the lower limbs, and arterial thrombosis causing ischemic brain stroke. Currently, no diagnostic criteria for pediatric APS exist, which probably results in an underestimation of the problem. Similarly, no therapeutic procedures for APS specific for children have yet been established. In the present literature review, we discussed data concerning APS in children and its role in cerebrovascular diseases, including pediatric arterial ischemic stroke, migraine and cerebral venous thrombosis.

Abstract
We present a unique case where a young man developed subtle cavernous sinus thrombosis (CST) due to underlying hypercoagulable state. He also had coexisting frontal lobe brain dural arteriovenous fistula (bdAVF). After CST developed, venous drainage from the optic nerve was redirected into the frontal lobe which was already under high venous pressure because of preexisting bdAVF. This caused backflow of venous blood into the optic nerve causing massive persistent optic nerve head swelling. Presumed acute venous hypertension event within bdAVF caused frontal mass effect presenting as seizure leading to thrombosis of bdAVF.

Abstract
We describe the CT and MRI patterns of cerebral venous sinus thrombosis (CVST) on the basis of the venous angioarchitecture and the underlying pathophysiological mechanism. We also investigated if any radiologic data exist to establish which patients can be followed conservatively and which warrant endovascular treatment. The clinical, CT-CTA and MRI-MRA findings of 11 patients (2 men; 9 women; 24 to 69 years-old) with CVST were reviewed. The morphological patterns of CVST were divided into two major groups: Vascular signs: spontaneous sinusal hyperdensity (9); spontaneous all-sequences hyperintensity (4); venous engorgement (9); empty delta sign (4); lack of sinusal contrast-enhancement (3); delayed sinusal transit-time (11); lack of flow-related signal (3). Parenchymal signs: mass effect and cortical sulcal effacement (8), white matter edema (7), venous ischemia (6), haemorrhagic infarct (3), breakdown of the blood-brain barrier (4), hydrocephalus (2). The clinical and radiologic pictures are related to cerebral venous angioarchitecture and underlying pathophysiologic mechanism of venous thrombosis. Reversibility of clinical symptoms and parenchymal lesions is far more frequent, because vessel damage slowly and progressively develops, whereas damage to brain tissue occurs later. Consequently, a prompt CT-MRI diagnosis may allow a good prognosis. Treatment using selective sinusal instillation of urokinase is considered only when the patient clinically and radiologically does not improve within the first two weeks after heparinization.

Abstract
A 51-year-old woman undergoing steroid treatment for systemic lupus erythematosus (SLE) was admitted to our hospital after developing a fever, consciousness disturbance and seizures, leading to a diagnosis of SLE-induced meningoencephalitis. Although steroid therapy improved her symptoms, she complained of post-lumbar puncture thunderclap headaches during follow-up, and cerebral venous thrombosis (CVT) was subsequently diagnosed on magnetic resonance venography and cerebral angiography. This is a rare case of neuropsychiatric SLE complicated by CVT during treatment for aseptic meningoencephalitis. The onset of aseptic meningoencephalitis and administration of the lumbar puncture and steroid therapy may have induced the development of the patient's CVT symptoms.

Abstract
Antiphospholipid syndrome (APS) is a multiorgan disease often affecting the central nervous system (CNS). Typically, neurological manifestations of APS include thrombosis of cerebral vessels leading to stroke and requiring prompt initiation of treatment with antiplatelet drugs or anticoagulant therapy. In these cases, alterations of the coagulation system at various levels caused by multiple effects of antiphospholipid antibodies (aPL) have been postulated to explain the vascular damage to the CNS in APS. However, several nonvascular neurological manifestations of APS have progressively emerged over the past years. Nonthrombotic, immune-mediated mechanisms altering physiological basal ganglia function have been recently suggested to play a central role in the pathogenesis of these manifestations that include, among others, movement disorders such as chorea and behavioral and cognitive alterations. Similar clinical manifestations have been described in other autoimmune CNS diseases such as anti-NMDAR and anti-VGCK encephalitis, suggesting that the spectrum of immune-mediated basal ganglia disorders is expanding, possibly sharing some pathophysiological mechanisms. In this review, we will focus on thrombotic and nonthrombotic neurological manifestations of APS with particular attention to immune-mediated actions of aPL on the vascular system and the basal ganglia.

Abstract
Down syndrome is the most commonly encountered chromosomal translation and has been associated with significant congenital abnormalities in various organ systems. Along with classic facial findings, it may involve the gastroenterologic, cardiac, ophthalmologic, endocrine, immunologic, orthopedic, or neurologic systems. With respect to the neurological system, a higher incidence of moyamoya, seizure disorders, strokes, and spinal ligamentous laxity has been described in these children. We have summarized the current available literature with respect to children who have Down syndrome and the varying neurological pathologic entities associated to help health care providers better understand these patients.

Abstract
Cerebral venous thrombosis (CVT) has usually been ascribed to prothrombotic conditions, oral contraceptives, pregnancy, malignancy, infection, head injury or mechanical precipitants. The case reported here illustrates two rare causes of CVT observed in the same patient: the presence of antiphospholipid antibodies associated with an asymptomatic cryptogenic organising pneumopathy (COP) which were considered the origin of the venous cerebral thrombosis and heparin-induced thrombocytopenia (HIT) which was responsible for the worsening of the thrombosis observed a few days after the introduction of treatment. Moreover, we provide here additional positive experience in the treatment of both, CVT and HIT, by fondaparinux with bridging to warfarin given their successful evolution under this anticoagulant option.

Abstract
Hypercoagulable states can be inherited or acquired. Inherited hypercoagulable states can be caused by a loss of function of natural anticoagulant pathways or a gain of function in procoagulant pathways. Acquired hypercoagulable risk factors include a prior history of thrombosis, obesity, pregnancy, cancer and its treatment, antiphospholipid antibody syndrome, heparin-induced thrombocytopenia, and myeloproliferative disorders. Inherited hypercoagulable states combine with acquired risk factors to establish the intrinsic risk of venous thromboembolism for each individual. Venous thromboembolism occurs when the risk exceeds a critical threshold. Often a triggering factor, such as surgery, pregnancy, or estrogen therapy, is required to increase the risk above this critical threshold.

Abstract
Cerebral venous sinus thrombosis is an uncommon disease marked by clotting of blood in cerebral venous, or dural sinuses, and, in rare cases, cortical veins. It is a rare but potentially fatal cause of acute neurological deterioration previously related to otomastoid, orbit, and central face cutaneous infections. After the advent of antibiotics, it is more often related to neoplasm, pregnancy, puerperium, systemic diseases, dehydration, intracranial tumors, oral contraceptives, and coagulopathies are the most common causes, but in 30% of cases no underlying etiology can be identified. It has been found in association with fibrous thyroiditis, jugular thrombosis after catheterization, or idiopathic jugular vein stenosis. Other factors include surgery, head trauma, arterio-venous malformations, infection, paraneoplastic, and autoimmune disease. This article presents a comprehensive review of cerebral venous sinus thrombosis etiologies.

Abstract
OBJECTIVE To analyze the clinical findings, treatment, outcome, and prevalence of cerebral venous thrombosis (CVT) in a large cohort of patients with Behçet's disease (BD) from a single center. METHODS We reported a series of 64 consecutive patients with CVT who fulfilled the international criteria for BD. Multivariate analysis was performed to define factors that affect prognosis. RESULTS Among a cohort of 820 patients with BD, CVT was present in 64 (7.8%). Compared with BD patients without CVT, those with CVT had lower parenchymal central nervous system involvement (4.7% versus 28.7%; P = 0.0001) and higher extraneurologic vascular lesions (62.5% versus 38.8%; P = 0.03). Up to 90% of patients responded to anticoagulation therapy without severe hemorrhagic complications. Neither steroid nor immunosuppressant use provided better outcome. Severe visual loss due to optic atrophy was the main complication of CVT, being found in 15% of patients. In multivariate analysis, papilledema (odds ratio [OR] 7.1, 95% confidence interval [95% CI] 1.6-31.9) and concurrent prothrombotic risk factors (OR 4.6, 95% CI 1.1-20.2) were independently associated with the occurrence of sequelae. Factors associated with relapse of thrombosis were concurrent prothrombotic risk factors (hazard ratio [HR] 4.9, 95% CI 1.5-15.4) and a peripheral venous thrombosis (HR 2.8, 95% CI 0.7-10.5). After a mean +/- SD followup of 8.2 +/- 6.9 years, 4 deaths unrelated to CVT were noted. CONCLUSION CVT in patients with BD may result in serious neurologic outcomes. Anticoagulation represents a safe and effective therapy. Extensive investigation of prothrombotic disorders should be considered.

Abstract
Antiphospholipid syndrome is a multisystem autoimmune disease, characterized by recurrent vascular thrombosis and/or pregnancy losses in the presence of persistently positive antiphospholipid antibodies. In clinical practice, testing for anticardiolipin antibodies and lupus anticoagulant is mandatory for the laboratory diagnosis of antiphospholipid syndrome. Identification of patients with antiphospholipid syndrome is important, as prophylactic anticoagulant therapy may prevent thrombosis from recurring, and treatment during pregnancy can improve fetal and maternal outcome.

Abstract
The antiphospholipid thrombosis syndrome, associated with anticardiolipin (aCL) or subgroup antibodies, can be divided into one of six subgroups (I-VI). There is little overlap (about 10% or less) between these subtypes, and patients usually conveniently fit into only one of these clinical types. Although there appears to be no correlation with the type, or titer, of aCL antibody and type of syndrome, the subclassification of thrombosis and aCL antibody patients into these groups is important from the therapy standpoint. This article also reviews the clinical presentations associated with each of these six subgroups.

Abstract
Antiphospholipid syndrome (APS) is a disorder characterized by a wide variety of clinical manifestations. Virtually any organ system or tissue may be affected by the consequences of large- or small-vessel thrombosis. There is a broad spectrum of disease among individuals with antiphospholipid antibodies (aPL). Patients may exhibit clinical features suggesting APS but not fulfill the International Criteria for a "definite" diagnosis. Seronegative APS patients demonstrate typical idiopathic thromboses but aPL are not initially detected. Patients defined with definite APS demonstrate nearly identical sites of venous and arterial thrombosis, regardless of the presence or absence of systemic lupus erythematosus. Microangiopathic APS may present with isolated tissue and organ injury or as the overwhelming "thrombotic storm" observed in catastrophic APS.

Abstract
Cerebral venous sinus thrombosis (CVT) after mild head injury is infrequent. A 38-year-old patient presented with a Glasgow Coma score (GCS) of 15 after a road traffic accident. CT scan revealed a temporal contusion. He was treated with measures to prevent cerebral oedema and anticonvulsants. Three weeks later he presented with features of pseudo-tumour syndrome. Investigations revealed the presence of cerebral venous sinus thrombosis, protein C deficiency and elevated titres of antiphospholipid antibodies. He was treated with anticoagulants and showed improvement. This case report highlights that multiple "hits" may lead to CVT and hence laboratory screening of patients with CVT is necessary even if the clinical situation seemingly provides sufficient explanation for a thrombotic event. The presence of acquired and inherited causes of thrombophilia need not always lead to symptomatic thrombosis. As illustrated by this case, a second hit, such as trauma, may be the precipitating factor that unmasks the prothrombotic state.

Abstract
Survivors of poliomyelitis sometimes travel by air with mobility assistance. However, prolonged seating during long-haul flights may also possibly produce stroke events on polio-inflicted patients. A 48-year-old polio-inflicted male suffered a stroke after an extended flight. A two-dimensional echocardiography was normal without detected patent foramen ovale or dyskinetic segment. The venodynamic variables were all within normal limits. MR Imaging studies revealed acute cerebral infarction in the distribution of the right middle cerebral artery and posterior watershed area. Hematological examination revealed positive anti-cardiolipin IgG antibody which might contribute to the risk of thrombosis as an underlying condition in addition to immobilization. This is the first presentation of ischemic stroke after a flight in a patient with prior poliomyelitis. In addition to decompression sickness, economy class stroke syndrome and postpoliomyelitis syndrome, the physician should also take other coagulation disorders into consideration during the investigation.

Abstract
This review will focus on recent developments in our understanding of cerebral venous and sinus thrombosis (CVST), as a side effect of combined oral contraceptives (COCs) use. Case-control studies have shown an increased risk of CVST in women who use COCs, especially third-generation contraceptives that contain gestodene or desogestrel. Several studies have indicated that the combination of COCs and thrombophilia greatly increased the risk of CVST, particularly in women with hyperhomocysteinaemia, factor V Leiden and the prothrombin-gene mutation. Women with thrombophilia who developed CVST while taking oral contraceptives should be definitively advised to stop using COCs. These patients should be considered for preventive therapy with low doses of heparin in prothrombotic situations such as bed rest or pregnancy, and the duration of anticoagulation should be considered on a case-by-case basis. Patients may be considered candidates for chronic treatment with antiplatelet agents. The best and most cost-effective screening method for thrombophilia in women who are planning to conceive is selective screening based on the presence of previous personal or family history of either prior extracerebral or cerebral venous thromboembolism events.

Abstract
Venous thromboses in the cerebrum are rare, within the context of both cerebrovascular disease and all of the venous thrombotic diseases. Its clinical aspects are polymorphic in their onset and in their acute phase, making diagnosis difficult. MRI with angiographic sequences can show the presence of a thrombus within a venous vessel and its consequences on the cerebral parenchyma. Hemostatic disorders are the leading causes of cerebral venous thrombosis, in particular, constitutional thrombophilia often associated with one or several promoting factors such as use of oral contraception. This explains the incidence peak among young women. The cause of approximately 20% of cerebral venous thromboses is never identified. Antithrombotic treatment must be prescribed on an emergency basis when the diagnosis is made, even if potentially hemorrhagic lesions are also present. The risk of permanent neurologic damage is approximately 13%.

Abstract
Superior saggital sinus thrombosis (SSST), which has a strong causal link with antiphospholipid syndrome, rarely occurs in patients with systemic lupus erythematosus (SLE). We describe a 34-year-old woman with SLE whose clinical problem was mild headache. Her serology indicated negative antiphospholipid, anticardiolipin antibodies and lupus anticoagulants. However, marked dilatation of the entire saggital sinus with scattered thrombi was observed in enhanced-, surface- and three-dimensional reconstructed CTs (3D-CTs) without abnormal intra-axial signal in brain MRI. The enhanced-, surface- and 3D-CTs are useful to detect silent dural sinus dilatation with scattered thrombi in a patient with SLE without any symptoms of SSST.

Abstract
The importance of cerebral disease in patients with the Hughes syndrome is now becoming more widely recognized. The range of neuropsychiatric manifestations of APS is comprehensive, and includes focal symptoms attributable to lesions in a specific area of the brain as well as diffuse or global dysfunction. Patients with APS frequently present with strokes and TIA, but a wide spectrum of other neurologic features-also including non thrombotic neurologic syndromes-has been described in association with the presence of aPL. The recognition of APS has had a profound impact on the understanding and management of the treatment of CNS manifestations associated with connective tissue diseases, in particular, SLE. Many patients with focal neurologic manifestations and aPL, who a few years ago would have received high-dose corticosteroids or immunosuppression, are often successfully treated with anticoagulation. In our opinion, testing for aPL may have a major diagnostic and therapeutic impact not only in patients with autoimmune diseases and neuropsychiatric manifestations, but also in young individuals who develop cerebral ischemia, in those with atypical multiple sclerosis, transverse myelitis, and atypical seizures. We would also recommend testing for aPL for young individuals found with multiple hyperintensity lesions on brain MRI in the absence of other possible causes,especially when under the age of 40 years. It is our practice to anticoagulate patients with aPL suffering from cerebral ischemia with a target INR of 3.0 to prevent recurrences. Low-dose aspirin alone (with occasional exceptions)does not seem helpful to prevent recurrent thrombosis in these patients. Our recommendation, once the patient has had a proven thrombosis associated with aPL, is long-term (possibly life-long) warfarin therapy. Oral anti coagulation carries a risk of hemorrhage, but in our experience the risk of serious bleeding in patients with APS and previous thrombosis treated with oral anticoagulation to a target INR of 3.5 was similar to that in groups of patients treated with lower target ratios. Although a double-blind crossover trial comparing low molecular weight heparin with placebo in patients with aPL and chronic headaches did not show a significant difference in the beneficial effect of low molecular weight heparin versus placebo, in our experience selected patients with aPL and neuropsychiatric manifestations such as seizures, severe cognitive dys-function, and intractable headaches unresponsive to conventional treatment may respond to anticoagulant treatment. The neurologic ramifications of Hughes syndrome are extensive, and it behoves clinicians in all specialties to be aware of this syndrome because treatment with anticoagulation may profoundly change the outlook for these patients.

Abstract
We report a case of dural venous sinus thrombosis (DVST) in a patient who developed seizures following exchange transfusion for treatment of acute chest syndrome associated with sickle cell disease. Evaluation with magnetic resonance imaging and magnetic resonance venography of the brain indicated left sigmoid sinus thrombosis. The history and laboratory evaluation did not reveal any other inherited or acquired hypercoagulable states. This is the fourth case of dural venous sinus thrombosis associated with sickle cell disease reported in literature. The patient had a favorable outcome with early treatment of unfractionated heparin.

Abstract
BACKGROUND Antiphospholipid antibodies have been associated with a clinical syndrome consisting thrombosis and recurrent, unexplained fetal loss. METHODS The literature pertaining to stroke associated with antiphospholipid antibodies, with emphasis on stroke in young adults, was reviewed. RESULTS Antiphospholipid antibodies are an independent risk factor for stroke in young adults in five of six studies. Multiple antiphospholipid specificities or the Lupus Anticoagulant were tested in addition to anticardiolipin antibody in these studies. In the single study that found no increased risk for stroke, only anticardiolipin antibody was tested. Only one of these studies evaluated for risk of recurrent stroke in young adults with antiphospholipid antibodies and found it to be increased. No treatment trials have been conducted in young adults with antiphospholipid antibodies and stroke. In the single treatment trial comparing aspirin and low-INR producing doses of warfarin to prevent recurrent stroke, both were found to be equally effective. CONCLUSIONS Antiphospholipid antibodies, particularly Lupus Anticoagulant, is an independent risk factor for first and possibly recurrent ischemic stroke in young adults. The best therapeutic strategy for preventing antiphospholipid antibody-associated recurrent stroke is not clear.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by recurrent vascular thrombosis and pregnancy losses. Laboratory diagnosis of APS relies on the demonstration of a positive anticardiolipin antibody test by an in-house or commercially available enzyme-linked immunosorbent assay, or on the presence of lupus anticoagulant by a coagulation-based test. Persistence of the positive results must be demonstrated, and other causes and underlying factors considered. Although it is universally recognized that the routine screening tests (anticardiolipin antibody or lupus anticoagulant) might miss some cases of APS, careful differential diagnosis and repeat testing are mandatory before the diagnosis of 'seronegative APS' can be made. Correct identification of patients with APS is important because prophylactic anticoagulant therapy can prevent thrombosis from recurring and treatment of affected women during pregnancy can improve fetal and maternal outcome.

Abstract
We report herein the case of 32-year-old woman with situs inversus, thrombophilia, antiphospholipid syndrome and severe premenstrual syndrome (PMS) with cerebral edema and epileptic seizures prior to menstruation. Seven days prior to regular menstruation she developed severe PMS, including headache, blurred vision, epileptic seizures, urinary incontinence, craving for food, depression and irritability. Papilledema was detected. Daily hormone analyses prior to and during menstruation confirmed an ovulatory cycle with extremely high progesterone, prolactin and insulin levels in the late luteal phase. From day 29 to day 31, progesterone and insulin decreased sharply and the estradiol/progesterone ratio changed, leading to epileptic seizures and the peak of her symptoms. Diuretic treatment was administered. All symptoms disappeared during the first few days of menstruation. A novel oral contraceptive, containing ethinyl estradiol and drospirenone, an antimineralocorticoid progestogen, was given during the next cycle and hormone analyses were repeated. All symptoms were reduced significantly and no cerebral edema and epileptic seizures occurred. This is the first report of a woman with severe PMS and cerebral edema being treated successfully with an oral contraceptive containing drospirenone.

Abstract
The factor II G20210A mutation and estrogen treatment are described as risk factors for cerebral venous thrombosis (CVT). We evaluated these known risk factors in a population of CVT patients and investigated the role of a combination of two polymorphisms in the promoter of the protein C gene (PC promoter CG haplotype), newly described as risk factors for deep venous thrombosis. A retrospective population of 26 CVT patients was compared with a control group of 84 healthy volunteers. After a multivariate analysis, we confirmed that the factor II G20210A mutation is an independent risk factor for CVT with odds ratio 4.7 (95% confidence interval, 2.83--75.3). We demonstrated that the CVT risk is increased when this mutation is associated either with the PC promoter CG haplotype (odds ratio=19.8; 95% confidence interval, 2.1--186.5) or, in females, with an estrogen treatment (odds ratio=24; 95% confidence interval, 2.26--127.3). In this work, the association of the factor II G20210A mutation and the PC promoter CG haplotype or estrogen treatment seems to be a particular risk for CVT.

Abstract
OBJECTIVE AND PURPOSE Neurological involvement is a common feature of the antiphospholipid syndrome (APS). A variety of thrombotic and non-thrombotic manifestations may accompany the presence of antiphospholipid antibodies (aPL). PATIENTS AND METHODS We retrospectively reviewed the prevalence of aPL in a cohort of over 350 unselected patients from a neurological clinic and studied the neurological manifestations of APS. RESULTS We found that within this cohort the prevalence of aPL was about 15%. Most of the patients with aPL suffered from strokes and transient ischemic attacks (TIA). One patient died from spinal infarction. Non-thrombotic manifestations also occurred in 40% of these patients, such as multiple sclerosis, chorea, seizures or cerebral malignancies. No significant correlations of the titres or different types of aPL and the type of the neurological symptoms could be found. In comparison to age and sex matched patients of the cohort where the presence of aPL could be excluded, the occurrence of non-thrombotic manifestations was significantly more frequent and varied in the group of patients with aPL. The higher incidence of stroke in the non-APS group could be explained by the significantly higher presence of other laboratory risk factors, mainly hypercholesterinemia. CONCLUSION This investigation indicates that aPL may play an important role in the etiology of various neurological syndromes.

Abstract
We describe the case of a young Lebanese woman with systemic lupus erythematosus (SLE) and a positive lupus anticoagulant (LAC) who developed right internal jugular vein and sigmoid sinus thrombosis. Coagulation studies showed that in addition to the LAC the patient was heterozygous for the factor V (FV) Leiden mutation, and C677T mutation of the methylenetetrahydrofolate reductase gene. The high prevalence of FV Leiden in the eastern Mediterranean region suggests that we should probably screen our SLE patients in this area, especially those with anticardiolipin antibodies and/or LAC who have no history of thrombosis, for this and other thrombophilia markers. The detection of such abnormalities may have major practical consequences for the long-term management of these patients to prevent further thrombotic episodes.

Abstract
Antiphospholipid syndrome has received considerable attention from the medical community because of its association with a number of serious clinical disorders, including arterial and venous thromboembolism, acute ischemic encephalopathy, recurrent pregnancy loss, thrombocytopenia, and livido reticularis. It can occur within the context of several diseases, mainly autoimmune disorders, and is then called secondary antiphospholipid syndrome. However, it may be also be present without any recognizable disease, or so-called primary antiphospholipid syndrome. There is no defined racial predominance for primary antiphospholipid syndrome, although a higher prevalence of systemic lupus erythematosus (SLE) occurs in African Americans and the Hispanic population. Multiple terms exist for this syndrome, some of which can be confusing. Lupus anticoagulant syndrome, for example, is a misleading term, because patients may not necessarily have SLE, and it is associated with thrombotic rather than hemorrhagic complications. To avoid further confusion, antiphospholipid syndrome is currently the preferred term for this clinical syndrome. Antiphospholipid antibodies are found in 1% to 5% of young healthy control subjects; however, the incidence increases with age and coexistent chronic disease. The syndrome occurs most commonly in young to middle-aged adults; however, it also can occur in children and the elderly. Among patients with SLE, the prevalence of antiphospholipid antibodies is high, ranging from 12% to 30% for anticardiolipin antibodies, and 15% to 34% for lupus anticoagulant antibodies. In general, anticardiolipin antibodies occur approximately five times more often then lupus anticoagulant in patients with antiphospholipid syndrome. This syndrome is the most common cause of acquired thrombophilia, associated with either venous or arterial thrombosis or both. It is characterized by the presence of antiphospholipid antibodies, recurrent arterial and venous thrombosis, and spontaneous abortion. Rarely, patients with antiphospholipid syndrome may have fulminate multiple organ failure, or catastrophic antiphospholipid syndrome. This is caused by widespread microthrombi in multiple vascular beds, and can be devastating. Patients with catastrophic antiphospholipid syndrome may have massive venous thromboembolism, along with respiratory failure, stroke, abnormal liver enzyme concentrations, renal impairment, adrenal insufficiency, and areas of cutaneous infarction. According to the international consensus statement, at least one clinical criterion (vascular thrombosis, pregnancy complications) and one laboratory criterion (lupus anticoagulant, antipcardiolipin antibodies) should be present for a diagnosis of antiphospholipid syndrome. The hallmark result from laboratory tests that defines antiphospholipid syndrome is the presence of antibodies or abnormalities in phospholipid-dependent tests of coagulation, such as dilute Russell viper venom time. There is no consensus for treatment among physicians. Overall, there is general agreement that patients with recurrent thrombotic episodes require life-long anticoagulation therapy and that those with recurrent spontaneous abortion require anticoagulation therapy and low- dose aspirin therapy during most of gestation. Prophylactic anticoagulation therapy is not justified in patients with high titer anticardiolipin antibodies with no history of thrombosis. However, if a history of recurrent deep vein thrombosis or pulmonary embolism is established, long-term anticoagulant therapy with international normalized ratio (INR) of approximately 3 is needed.

Abstract
The antiphospholipid (aPL) antibody syndrome is an autoimmune condition in which vascular thrombosis and/or recurrent pregnancy losses occur in patients with laboratory evidence for antibodies that bind to phospholipids. There have been significant advances in the recognition of the role of phospholipid-binding cofactors, primarily beta2GPI, as the true immunologic targets of the antibodies. Recent evidence suggests that the antibodies disrupt phospholipid-dependent anticoagulant mechanisms and/or that aPL antibodies induce the expression of procoagulant and proadhesive molecules on endothelial cells. Current diagnosis is based on clinical findings and empirically derived tests, such as assays for antibodies that bind to phospholipids or putative cofactors and coagulation assays that detect inhibition of phospholipid-dependent coagulation reactions. Current treatment relies primarily on anticoagulant therapy. Research advances are expected to bring mechanistically based diagnostic tests and improved therapy that target the roots of the disease process.

Abstract
Thrombophilia is the predisposition to venous thromboembolism and is caused by inherited and acquired factors, alone or in combination. With the discovery of APC resistance and the prothrombin gene mutation, more than half of all patients with clinical characteristics of thrombophilia are now diagnosed with an inherited disorder. The hypercoagulable work-up of patients with venous thromboembolism is important, because the causes can influence the duration and management of anticoagulation therapy, as well as affect other decisions regarding life and health issues.

Abstract
Antiphospholipid antibodies are associated strongly with thrombosis and are the most common of the acquired blood protein defects causing thrombosis. Although the precise mechanisms whereby antiphospholipid antibodies alter hemostasis to induce a hypercoagulable state remain unclear, numerous theories, as previously discussed, have been advanced. The most common thrombotic events associated with ACLAs are deep vein thrombosis and pulmonary embolus (type I syndrome), coronary or peripheral artery thrombosis (type II syndrome), or cerebrovascular/retinal vessel thrombosis (type III syndrome), and occasionally patients present with mixtures (type IV syndrome). Patients with type V disease are those with antiphospholipid antibodies and RMS. It is as yet unclear how many seemingly normal individuals who may never develop manifestations of antiphospholipid syndrome (type VI) harbor asymptomatic antiphospholipid antibodies. The relative frequency of ACLAs in association with arterial and venous thrombosis strongly suggests that they should be looked for in any individual with unexplained thrombosis; all three idiotypes (IgG, IgA, and IgM) should be assessed. Also, the type of syndrome (I-VI) should be defined, if possible, because this identification may dictate both the type and the duration of immediate and long-term anticoagulant therapy. Unlike those patients with ACLAs, patients with primary LA-thrombosis syndrome usually have venous thrombosis. Because the aPTT is unreliable in patients with LA (prolonged in only approximately 40%-50% of patients) and usually is not prolonged in patients with ACLAs, definitive tests, including ELISA for ACLA, the dilute Russell's viper venom time for LA, hexagonal phospholipid-neutralization procedure, and B-2-GP-I (IgG, IgA, and IgM) should be ordered immediately when suspecting antiphospholipid syndrome or in individuals with otherwise unexplained thrombotic or thromboembolic events. If these test results are negative, subgroups also should be assessedin the appropriate clinical setting. Most patients with antiphospholipid thrombosis syndrome will fail to respond to warfarin therapy, and except for retinal vascular thrombosis, may fail some types of antiplatelet therapy, so it is of major importance to make this diagnosis so patients can be treated with the most effective therapy for secondary prevention-LMWH or unfractionated heparin in most instances and clopidogrel in some instances.

Abstract
Primary anti-phospholipid syndrome (APS) is a thrombophilic state characterized by recurrent arterial and venous thrombosis, recurrent pregnancy loss, and the presence of circulating anti-phospholipid antibodies that may be responsible for thrombophilia and pregnancy morbidity. Ophthalmologic features are present in 15-88% of the patients with primary APS, thus ophthalmologists are one of the first physicians to whom the patient will present. An accurate diagnosis may save the patient from recurrent, potentially life-threatening thrombosis. In the U.S.A., an estimated 35,000 new cases of APS-related venous thrombosis occur each year in a population that is several decades younger than the patient population typically affected by thrombosis. Clinical features, such as chorea, transverse myelitis, cardiac valvular lesions, and accelerated atherosclerosis, are hypothesized to be due to a direct tissue-antibody interaction and cannot be explained purely by thrombosis. The use of recently proposed, well-defined diagnostic criteria, and better standardization of laboratory assays for the anti-phospholipid antibodies should help enable epidemiological surveys to establish the prevalence of these antibodies in patients with thrombosis and in the general population. Diagnosis of APS should be considered in all patients with recurrent systemic or ocular thrombosis in the absence of known risk factors. Several well-designed prospective studies show an increased risk of thrombosis in the presence of medium to high antibody level. With ocular involvement in as many as 88% of APS patients, an ophthalmic assessment should be an integral part of the clinical work-up of any patient with suspected or confirmed APS. The presence of isolated ocular thrombophilia with persistently elevated anti-phospholipid antibodies or lupus coagulant should confirm the diagnosis of APS. Management of these patients must be a multi-disciplinary effort with either a rheumatologist or a hematologist having the overall responsibility for coordinating treatment and monitoring the patient's immune status and anticoagulation. Treatment of isolated ocular thrombophilia in the presence of moderate to high titers of antiphospholipid antibodies should be on the same principles as patients with APS to prevent recurrent ocular or cerebral thrombosis.

Abstract
Antiphospholipid antibodies are strongly associated with thrombosis and are the most common of the acquired blood protein defects causing thrombosis. Although the precise mechanism(s) whereby antiphospholipid antibodies alter hemostasis to induce a hypercoagutable state remain unclear, numerous theories, as previously discussed, have been advanced. The most common thrombotic events associated with anticardiolipin antibodies are deep vein thrombosis and pulmonary embolus (type I syndrome), coronary or peripheral artery thrombosis (type II syndrome), or cerebrovascular/retinal vessel thrombosis (type II syndrome); occasionally, patients present with mixtures of these types (type IV syndrome). Type V patients are those with antiphospholipid antibodies and RMS. It is as yet unclear how many seemingly normal individuals who may never develop manifestations of antiphospholipid syndrome (type VI) harbor asymptomatic antiphospholipid antibodies. The relative frequency of anticardiolipin antibodies in association with arterial and venous thrombosis strongly suggests that these should be looked for in any individual with unexplained thrombosis; all three idiotypes (IgG, IgA, and IgM) should be assessed. Also, the type of syndrome (I through VI) should be defined if possible, as this may dictate both type and duration of both immediate and long-term anticoagulant therapy. Unlike those with anticardiolipin antibodies, patients with primary lupus anticoagulant thrombosis syndrome usually experience venous thrombosis. Because the aPTT is unreliable inpatients with lupus anticoagulant (prolonged in only about 40 to 50% of patients) and is not usually prolonged in patients with anticardiolipin antibodies, definitive tests, including ELISA for anticardiolipin antibodies, the dRVVT for lupus anticoagulant, hexagonal phospholipid neutralization procedure, and beta-2-GP-I (IgG, IgA, and IgM) should be immediately ordered when suspecting antiphospholipid syndrome or in individuals with otherwise unexplained thrombotic or thromboembolic events. If results of these tests are negative, in the appropriate clinical setting, subgroups should also be assessed. Finally, most patients with antiphospholipid thrombosis syndrome will fail warfarin therapy and, except for retinal vascular thrombosis, may fail some types of antiplatelet therapy; thus it is of major importance to make this diagnosis so that patients can be treated with the most effective therapy for secondary prevention--LMWH or UH in most instances, and clopidogrel in some instances.

Abstract
Neurologic disorders are among the most prominent clinical manifestations associated with the antiphospholipid syndrome. Such neurologic disorders are predominantly related to focal central nervous system thrombo-occlusive events. This review summarizes the latest data regarding the clinical aspects of stroke and other neurologic manifestations associated with antiphospholipid antibodies.

Abstract
OBJECTIVES To describe the occurrence of cerebral venous thrombosis in a 40-year-old man whose cerebral event was induced by a poor golf swing, to review the literature on possible mechanisms producing venous thrombosis, and to compare this case with the literature. BACKGROUND Headache is the most frequent symptom in patients with cerebral venous thrombosis. However, patients presenting with a headache due to cerebral venous thrombosis are uncommon. The known risk factors for thrombosis include both acquired and genetic factors. When the interaction of these two groups occurs, the magnitude of this interaction is thought to produce a dynamic state that can favor thrombosis. Our case report illustrates that moderate levels of anticardiolipin antibodies together with the mild trauma of a golf swing can induce a cerebral venous thrombosis. This case also suggests that although headache is rarely due to cerebral venous thrombosis, it should be excluded by good medical acumen and testing. RESULTS Minor trauma induced by a poor golf swing was chronologically related to the development of a progressive cerebral venous thrombosis. The patient had none of the risk factors associated with a predisposition to venous thrombosis: hypercoagulable state, concurrent infection, pregnancy/puerperium, collagen vascular disorder, malignancy, migraine, false-positive VDRL, previous deep vein thrombosis, renal disease, factor V Leiden, or a hematological disorder. There was no anatomical abnormality that would predispose the patient to a cerebral venous thrombosis. The only laboratory abnormality was a moderate anticardiolipin antibody level (25 GPL). The patient was placed on warfarin sodium therapy and is currently without clinical sequela from the venous thrombotic event. CONCLUSIONS Under certain circumstances, minor trauma can induce cerebral venous thrombosis. A review of the literature indicates that cerebral venous thrombosis in the presence of anticardiolipin antibodies and in the absence of systemic lupus erythematosus is a rare event. Previously, only major traumatic events have been reported to be associated with cerebral venous thromboses. The chronological development of cerebral venous thrombosis after a faulty golf swing strongly indicates that given a background of moderate levels of anticardiolipin antibodies, even minor trauma can induce a venous thrombotic event.

Abstract
Since early recurrence occurs in at least 10% of patients presenting with their first stroke in childhood in the reported series, the search for modifiable risk factors should be a priority. Risk factors for stroke in adults include hypertension, diabetes, and smoking, as well as cardiac disease and sickle cell anemia; asymptomatic cerebrovascular disease and transient ischemic events may predict stroke in this age group. The investigation of a child with a stroke has traditionally focused on finding a single cause rather than looking for risk factors to which the patient may be exposed life long. Approximately half of children presenting with stroke have a known predisposing condition, but some have unexpected pathologies such as primary cerebrovascular disease associated with congenital heart anomalies, or may have modifiable risk factors such as hypertension associated with sickle cell disease. The literature on children presenting with initially unexplained (cryptogenic) stroke suggests that there is a daunting list of possible causes, but since the series have mainly been small, it has been difficult to evaluate the relative importance of the reported associations. This paper reviews the literature on congenital, genetic, and acquired risk factors for stroke in childhood, and includes data from the large series of patients seen at Great Ormond Street Hospital over the past 10 years. The majority have arteriographic abnormalities and there is little evidence for asymptomatic cardiac disease. Genetic predisposition, trauma, infection, and nutritional deficiencies appear to be important, although case-control studies will be required to prove causation. Appropriate screening for modifiable risk factors may lead to prevention of recurrence in some patients. In the long term, an understanding of the multiple etiologies of childhood cerebrovascular disease and ischemic stroke may lead to primary prevention in this age group, and perhaps in adults.
