Abstract
Antiphospholipid Syndrome (APS) is an autoimmune disease which was defined in the early 1980s. The principal features include thromboembolic events and/or pregnancy losses in association with antiphospholipid antibodies (aPL). As an historical note, the full-blown picture of the syndrome resembles the illness suffered by Anne Stuart, Queen of England in the XVIII century, whose repeated miscarriages caused the end of the royal Stuart line and the Hanoverian succession. The identification of aPL started in the early XX century and was linked to the introduction of the serological test for the diagnosis of syphilis. This involves a reaction between an antibody (reagin) and a phospholipid antigen derived from bovine heart (cardiolipin). Later on, it was observed that not all subjects with a positive test had syphilis, and that the so called "false positive reaction" was often reported in patients with systemic lupus erythematosus. Different tests for the identification of aPL were subsequently developed: first lupus anticoagulant (1971) and then immunoassays for anticardiolipin (1983) and anti-beta2 glycoprotein I (1990) antibodies. In the same period the association between the presence of circulating aPL and thrombotic and obstetric events was established, both in patients with autoimmune diseases and in otherwise healthy subjects, leading to the identification of APS as a distinct autoimmune disease. This has allowed better diagnosis and more targeted treatment for many patients.

Abstract
OBJECTIVE Antiphospholipid syndrome (APS) is a chronic autoimmune disease with a high prevalence in females. Published data have identified pregnant women with APS may suffer from recurrent miscarriage, fetal death. However, the association between antiphospholipid antibody (aPL) and fetal growth restriction (FGR) remains controversial. This study aims to systematically review the literature on population-based studies investigating an association between aPL and FGR. METHODS The literature was searched on 1 November, 2021, using Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL), following the MOOSE checklist. Study inclusion criteria focused on peer-reviewed published articles that reported an association between aPL and FGR. Quality assessment was performed based on the Newcastle-Ottawa scale. The between-study heterogeneity was assessed by the Q test. Publication bias was assessed by funnel plots. RESULTS Twenty-two studies (with 11745 pregnant women) were included in the final analysis. Pooled odds ratio for association of aPL, anticardiolipin antibodies (ACA), anti-beta2 glycoprotein 1 antibodies (β2GP1), and FGR was 1.26 (95%CI 1.12, 1.40), 2.25 (95%CI 1.55, 2.94), and 1.31 (95% CI 1.12, 1.49), respectively. Lupus anticoagulant (LA) did not increase the chance of FGR (OR 0.82, 95%CI 0.54, 1.10). CONCLUSIONS Our meta-analysis showed that aPL increased the risk of FGR. The risk of FGR varies with the aPL types. ACA and β2GP1 are strongly associated with FGR. There are currently insufficient data to support a significant relationship between LA and FGR.

Abstract
The antiphospholipid syndrome is characterized by antibodies directed against phospholipid-binding proteins and phospholipids attached to cell membrane receptors, mitochondria, oxidized lipoproteins, and activated complement components. When antibodies bind to these complex antigens, cells are activated and the coagulation and complement cascades are triggered, culminating in thrombotic events and pregnancy morbidity that further define the syndrome. The phospholipid-binding proteins most often involved are annexins II and V, β2-glycoprotein I, prothrombin, and cardiolipin. A distinguishing feature of the antiphospholipid syndrome is the "lupus anticoagulant". This is not a single entity but rather a family of antibodies directed against complex antigens consisting of β2-glycoprotein I and/or prothrombin bound to an anionic phospholipid. Although these antibodies prolong in vitro clotting times by competing with clotting factors for phospholipid binding sites, they are not associated with clinical bleeding. Rather, they are thrombogenic because they augment thrombin production in vivo by concentrating prothrombin on phospholipid surfaces. Other antiphospholipid antibodies decrease the clot-inhibitory properties of the endothelium and enhance platelet adherence and aggregation. Some are atherogenic because they increase lipid peroxidation by reducing paraoxonase activity, and others impair fetal nutrition by diminishing placental antithrombotic and fibrinolytic activity. This plethora of destructive autoantibodies is currently managed with immunomodulatory agents, but new approaches to treatment might include vaccines against specific autoantigens, blocking the antibodies generated by exposure to cytoplasmic DNA, and selective targeting of aberrant B-cells to reduce or eliminate autoantibody production.

Abstract
Antiphospholipid syndrome, also known as 'Hughes Syndrome', is an autoimmune disease characterised by a set of clinical manifestations, almost all of which are direct or indirect sequelae of a hypercoagulable state involving the venous, and to a lesser extent the arterial vasculature. The incidence and prevalence of antiphospholipid syndrome are estimated at approximately 5 de novo cases per 100 000 per year and 40-50 cases per 100 000 individuals, respectively. The clinical spectrum of antiphospholipid syndrome involves haematological (thrombocytopaenia, venous thrombosis), obstetrical (recurrent pregnancy loss), neurological (stroke, transient ischaemic attack, migraine, seizures, cognitive dysfunction, chorea, transverse myelitis, multiple sclerosis), cardiovascular (cardiac valve disease), dermatological (livedo reticularis and racemosa, skin ulceration and necrosis), renal (glomerulonephritis, renal thrombotic microangiopathy) and orthopaedic (avascular necrosis of bones, non-traumatic fractures) manifestations, among others. In addition to the classical antiphospholipid antibodies, namely anticardiolipin antibodies and lupus anticoagulant, new autoantibodies and antibody complexes of different immunoglobulin subtypes (IgA, IgG, IgM) are now recognised as significant contributors to the pathogenesis of antiphospholipid syndrome. Anticoagulation remains the cornerstone in the management of antiphospholipid syndrome; nevertheless, new drugs and therapeutic strategies are being tested, and some have been found effective for the primary and secondary thromboprophylaxis in antiphospholipid syndrome.

Abstract
PURPOSE OF REVIEW Antiphospholipid antibody syndrome (APS) is characterized primarily by thrombosis and pregnancy morbidity. Chronic vascular lesions can also occur. While the underlying mechanisms of these vascular lesions are not entirely known, there have been multiple theories describing the potential process of vasculopathy in APS and the various clinical manifestations associated with it. RECENT FINDINGS Recently, it has been demonstrated that endothelial proliferation in kidneys can be explained by the activation of the mammalian target of rapamycin complex (mTORC) pathway by antiphospholipid antibodies (aPL). These data support the existence of an APS-related vasculopathy in different locations which can explain-in part-the different manifestations of APS. This review focuses on the various manifestations of APS as a result of APS-related vasculopathy, as well as pathophysiology, current screening, and treatment options for clinicians to be aware of.

Abstract
To investigate the effects of antiphospholipid antibodies on establishment of pregnancy and changes in hormones such as estradiol-17ß (E2) and progesterone (P) levels in circulation. Hence, mice were immunized with human β2-Glycoprotein I (β2GPI) and the effect of these antibodies on fetuses weight, placental obsrvation, Serum levels of P and E2 in pregnant mice, hematological were observed. Immunization of mice with human β2-GPI resulted in elevated levels of antiphospholipid antibodies. The experimentally induced antiphospholipid syndrome mouse showed higher rate of fetal resorption, low number of viable fetuses, and "placental abnormalities". In these animals, serum E2 and P levels were reduced significantly. In addition, the blood cell variation among APS induced and control mice were determined. No significant variations were observed in number of Red Blood Cell count, White Blood Cell count and Hemoglobin content, while platelet number was significantly reduced as compared to control. These results clearly demonstrate that human β2-GPI might be involved in causing gestational failure in APS by exerting their effect on serum hormones.

Abstract
Antiphospholipid antibodies are increasingly being identified as a cause of arterial and venous thrombosis as well as fetal wastage syndrome via placental vascular thrombosis. The antiphospholipid thrombosis syndromes should be considered and searched for when suggestive clinical findings are present or when unexplained arterial or venous thrombosis occurs. Noting the presence and type of antiphospholipid antibody thrombosis syndrome assumes major importance with respect to not only making an accurate diagnosis of cause of thrombosis but also in selecting effective antithrombotic therapy. The antiphospholipid thrombosis syndromes and the thrombotic and other clinical manifestations span almost all medical specialities and should be construed as a truly multidisciptinary medical problem. Key Words: Thrombosis-Anticardiolipin antibody—Lupus anticoagulant.

Abstract
The alterations of the inflammatory and thrombotic components in patients with cancer are not clearly understood. The purpose of this study was to profile markers of inflammation and thrombotic activation specifically in the patients with bladder cancer undergoing radical cystectomy. For this study, 134 samples were collected from patients undergoing radical cystectomy. Antiphospholipid antibodies (immunoglobulin G subtype), microparticles, and antiglycosaminoglycan antibodies were measured with a commercially available enzyme-linked immunosorbent assay kits. These biomarkers were compared in patients with bladder cancer and normal individuals (n = 20). Patients had an average value of 6.7 ± 11.9 ng/mL (median: 2.8, confidence interval: 4.69-8.75, andPvalue: .0038) of antiphospholipid antibodies versus normal individuals 1.96 ± 0.9 ng/mL (median: 1.8 and confidence interval: 1.5-2.35). Microparticles level in patients was 8.31 ± 6.14 ng/mL, (median: 6.1, confidence interval: 7.26-9.37, andPvalue: <.0001) versus normal individuals 3.57 ± 2.34 ng/mL (median: 2.85 and confidence interval: 2.476-4.664). The antiglycosaminoglycan antibodies in patients had an average value of 0.22 ± 0.1 optical density (OD; median: 0.2, confidence interval: 0.21-0.24, andPvalue: .0213) compared to normal individuals 0.25 ± 0.08 OD (median: 0.25 and confidence interval: 0.22-0.23). The correlation of antiglycosaminoglycan antibodies with antiphospholipid antibodies showed Spearmanrvalue = .2364 (95% confidence interval: 0.05-0.4 andPvalue .009). The correlation of antiglycosaminoglycan antibodies versus microparticles showed Spearmanr= -.195 (95% confidence interval: 0.37-0.01 andPvalue .0321). These data suggest that patients with bladder cancer have subclinical activation of thrombotic and inflammatory processes that may be further exacerbated by surgical procedures and lead to venous thromboembolism-related complications.

Abstract
ABSTRACT:The records of fifteen patients referred for neurological assessment and found to have lupus anticoagulant or elevated anticardiolipin antibodies were reviewed. The mean age for females in the group was 29.4 years and for males was 35. A diagnosis of migraine, either as an acute or chronic problem, was made in 10 (66%) of these patients. Seven of the 15 patients had ischemic stroke and two patients had other thrombotic complications associated with lupus anticoagulant. Three of the nine female patients with migraine had histories of spontaneous abortions. All migraine patients experienced transient or more prolonged neurological deficits with their headaches. An association between lupus anticoagulant and migraine can only be suggested. Data on the incidence of migraine in patients with lupus anticoagulant in the general medical population does not exist. Furthermore the prevalence of lupus anticoagulant in migraine sufferers is unknown. Therefore further studies are required to investigate this possible association.

Abstract
Idiopathic non-cirrhotic portal hypertension (INCPH) is a rare disease characterized of intrahepatic portal hypertension in the absence of cirrhosis or other causes of liver disease and splanchnic venous thrombosis. The etiology of INCPH can be classified in five categories: 1) immunological disorders (i.e. association with common variable immunodeficiency syndrome, connective tissue diseases, Crohn’s disease, etc.), 2) chronic infections, 3) exposure to medications or toxins (e.g. azathioprine, 6- thioguanine, arsenic), 4) genetic predisposition (i.e. familial aggregation and association with Adams-Oliver syndrome and Turner disease) and 5) prothrombotic conditions (e.g. inherited thrombophilias myeloproliferative neoplasm antiphospholipid syndrome). Roughly, INCPH diagnosis is based on clinical criteria and the formal exclusion of any other causes of portal hypertension. A formal diagnosis is based on the following criteria: 1) presence of unequivocal signs of portal hypertension, 2) absence of cirrhosis, advanced fibrosis or other causes of chronic liver diseases, and 3) absence of thrombosis of the hepatic veins or of the portal vein at imaging. Patients with INCPH usually present with signs or symptoms of portal hypertension such as gastro-esophageal varices, variceal bleeding or splenomegaly. Ascites and/or liver failure can occur in the context of precipitating factors. The development of portal vein thrombosis is common. Survival is manly limited by concomitant disorders. Currently, treatment of INCPH relies on the prevention of complications related to portal hypertension, following current guidelines of cirrhotic portal hypertension. No treatment has been studied aimed to modify the natural history of the disease. Anticoagulation therapy can be considered in patients who develop portal vein thrombosis.

Abstract
CONTEXT Portal Hypertension (PH) is a progressive complication due to chronic liver disease. In addition to pathophysiologic changes in the micro-circulation, in PH are established fibrous tissue (periportal fibrous septal) and regenerative hyperplastic nodules (from micro- to macro-nodules) promoting hepatic architectural distortion. EVIDENCE ACQUISITION A literature search of electronic databases was undertaken for the major studies published from 1981 to today. The databases searched were: PubMed, EMBASE, Orphanet, Midline and Cochrane Library. We used the keywords: "portal hypertension, children, immune system, endocrine system, liver fibrosis". RESULTS It is believed that PH results from three "phenotype": ischemia-reperfusion, involving nervous system (NS); edema and oxidative damage, involving immune system; inflammation and angiogenesis, involving endocrine system. However, its exact cause still underdiagnosed and unknown. CONCLUSIONS PH is a dynamic and potentially reversible process. Researchers have tried to demonstrate mechanisms underlying PH and its related-complications. This review focuses on the current knowledge regarding the pathogenesis, and immune, endocrine-metabolic factors of disease. The strong positive association between immune system and development of PH could be efficient to identify non-invasive markers of disease, to modify prognosis of PH, and to development and application of specific and individual anti-inflammatory therapy.

Abstract
Knowledge of antiphospholipid antibodies and their impact on pregnancy continues to evolve. A variety of antiphospholipid antibodies have been identified, but not all of them seem to be pathologic for pregnancy outcome. Understanding of which patients are at high risk for adverse pregnancy outcome and the most effective treatment will require clinical trials based on risk stratification and long-term follow-up of infants.

Abstract
The aim of this study is to explore the role of plasminogen activator inhibitor type 1 (PAI-1) in primary and secondary antiphospholipid syndrome (APS). Thirty patients of APS (24 primary and 6 secondary) were recruited in the study who fulfilled the revised Sapporo criteria. Control groups comprised of age- and sex-matched 10 healthy volunteers and 10 patients each of systemic lupus erythematosus and rheumatoid arthritis without any antecedent thrombotic event and/or APS-related pregnancy morbidity. Serum samples were tested for PAI-1 antigen levels measured by quantitative ELISA. Positivity rate of PAI-1 in patients of primary, secondary as well as total APS patients was significantly higher in relation to age- and sex-matched healthy volunteers (p = 0.010, p = 0.003 and p < 0.001, respectively). Mean ± SEM levels of PAI-1 in primary and secondary as well as total APS patients were significantly higher (p = 0.006, p < 0.001 and p < 0.001) in relation to healthy controls. Correlation of PAI-1 levels (mean ± SEM) with clinical characteristics, that is, thrombosis and pregnancy morbidity, revealed significantly higher levels of PAI-1 (p < 0.001) in patients having thrombosis and APS-related pregnancy morbidity. Elevated PAI-1 level leading to impaired fibrinolysis plays a significant role in producing hypercoagulable state in primary and secondary APS.

Abstract
The differences in individual efficacy of two Sairei-to preparations (Sojyutu-Sairei-to and Byakujyutu-Sairei-to) on antinuclear antibody (ANA) and anticardiolipin antibody (ACLA) positive recurrent spontaneous abortion (RSA) was analyzed in 52 patients (a total of 61 treatment sessions). Patients who failed to respond to initial treatment with Sojyutu-Sairei-to were additionally treated with Byakujyutu- Sairei-to, and the time course of ANA and ACLA titers in these patients was analyzed. ACLA titers were decreased significantly by the treatment of Byakujyutu-Sairei-to, however, the percentage of successfully prevented abortion cases did not differ significantly between the Sojyutu-Sairei-to treatment group and the Byakujyutu-Sairei-to treatment group. ACLA titer was decreased in all 10 cases where abortion was successfully prevented by the treatment with Sojyutu-Sairei-to or Byakujyutu-Sairei-to. In the cases where both ANA and ACLA were decreased following treatment with Sojyutu-Sairei-to or Byakujyutu-Sairei-to, the percentage of cases rated as "Kyo" and "Rikan" were significantly higher in the Byakujyutu-Sairei-to group. These results indicate that Byakujyutu-Sairei-to is effective against ACLA positive RSA through the antibody-reducing activity, which differs from that of Sojyutu-Sairei-to in individual cases. On the basis of these results, Sairei-to therapy, which is superior to aspirin and heparin in terms of efficacy and safety, is recommended as the first-line therapy for RSA of autoimmune etiologies. Furthermore, to elevate the percentage of successfully prevented abortions, it is advisable to select one of the two Sairei-to preparations (Sojyutu-Sairei-to and Byakujyutu-Sairei-to) on the basis of differential diagnosis using the methods of Oriental medicine.

Abstract
Idiopathic noncirrhotic portal hypertension (INCPH) is characterized by an increased portal venous pressure gradient in the absence of a known cause of liver disease and portal vein thrombosis. In contrast to the high prevalence of this disorder in India, INCPH is a rare disease in the Western world. The etiology of INCPH can be divided in five categories: chronic infections, exposure to medication or toxins, thrombophilia, immunological disorders, and genetic disorders. Multifactorial etiology can also be encountered. Chronic abdominal infection is incriminated as the most important etiological factor in Eastern patients and thrombophilia in Western patients. The majority of patients with INCPH initially present with signs or complications of portal hypertension (mainly variceal bleeding and splenomegaly). These patients usually have preserved liver function. Liver function impairment occurs mainly in the context of intercurrent conditions. Patients with INCPH are often clinically and radiologically misdiagnosed as liver cirrhosis, so that a liver biopsy is indispensable to discriminate cirrhosis from INCPH. Histopathological characteristics of INCPH are heterogeneous, demonstrating overlap between several pathological entities (e.g., hepatoportal sclerosis, nodular regenerative hyperplasia, and incomplete septal cirrhosis). Even though hemodynamical changes in INCPH patients are not comparable to those in cirrhotics, prophylaxis and treatment of variceal bleeding are recommended to be similar. Anticoagulation therapy must be considered only in patients who develop portal vein thrombosis. INCPH has been considered a disorder with a relatively benign disease course. However, liver failure, hepatic encephalopathy, and hepatopulmonary syndrome can occur and are considered indications for liver transplantation.

Abstract
Antiphospholipid syndrome (APS) is a systemic disease that causes venous and arterial thrombosis in virtually any organ and is responsible for fetal losses and pregnancy disorders. Previously, APS was thought to be present mainly in patients with systemic lupus erythematosus. The spectrum of clinical manifestations is wide, because the thrombotic process may involve arterial and venous vessels of any size in any organ. At present, there is no evidence to support or refute specific treatment strategies for primary prophylaxis of thrombosis.

Abstract
OBJECTIVE To estimate the effect of combined heparin and aspirin compared with aspirin monotherapy in pregnant women with antiphospholipid syndrome and recurrent pregnancy loss. DATA SOURCES We searched the PubMed database up to December 2009 for English-language studies using the key words "aspirin AND (heparin OR low molecular weight heparin), (antiphospholipid OR anticardiolipin OR aPL) AND pregnancy." METHODS OF STUDY SELECTION Two hundred ninety- two studies were initially screened. Randomized controlled trials comparing the effect of heparin (unfractionated heparin or low molecular weight heparin) plus aspirin compared with aspirin alone on the live-birth rate in women with a history of at least two miscarriages and antiphospholipid antibodies were eligible. TABULATION, INTEGRATION, AND RESULTS The pooled effect of unfractionated heparin and low molecular weight heparin was evaluable in three and two randomized controlled studies, respectively, with regard to live births, which was the major outcome. Overall, treatment effects were in favor of heparin against first-trimester losses (odd ratio [OR] 0.39, 95% confidence interval [CI] 0.24-0.65, number needed to treat 6). More specifically, unfractionated heparin displayed a significant effect (OR 0.26, 95% CI 0.14-0.48, number needed to treat 4), while the pooled effect of low molecular weight heparin was insignificant (OR 0.70, 95% CI 0.34-1.45). Combination therapy of either unfractionated heparin or low molecular weight heparin with aspirin failed to display any significant effect in the prevention of late-pregnancy losses. No significant differences were observed between treatment and control groups for any other outcomes. CONCLUSION The combination of unfractionated heparin and aspirin confers a significant benefit in live births. However, the efficacy of low molecular weight heparin plus aspirin remains unproven, highlighting the urgent need for large controlled trials.

Abstract
In a prospective comparative study we screened 112 women with a past history either of pre-eclampsia, eclampsia, recurrent abortion, IUGR, IUFD or abruptio placentae, with no apparent aetiology and a demographically matched cohort of 106 women having a past history of uncomplicated pregnancy outcome for the presence of antiphospholipid antibodies (aPL) and their significance. In the former group, the prevalence of aPL ranged from 10-46.87% compared with 8.49% in the later group. In women with the presence of aPL, the incidence of pre-eclampsia, early onset pre-eclampsia and abruptio placentae were 25%, 14.58% and 18.75%, respectively. In the same group, the abortion rate was 25% and live-birth rate was 64.58% with IUFD rate of 10.42%. Fetal morbidity rates were also higher in the mothers with aPL positivity, the incidence of IUGR was 27.08% and oligohydramnios was 33.33% in them. All these complications were statistically significant when compared with those of aPL negative mothers.

Abstract
PROBLEM An immune-based aetiology is one of the several accepted causes for recurrent foetal loss (RFL). However, most of the immunological theories have not fulfilled the criteria for causality. This is a review of the various immunological causes of RFL and the outcome of different treatment protocols. METHOD OF STUDY Both auto- and alloimmune maternal immunological abnormalities have been proposed to account for foetal loss. Among the autoimmune factors, anti-phospholipid antibodies (APAs) have been demonstrated to be the strongest risk factors for foetal loss, the prevalence of which is as high as 40% in women with RFL. Other autoimmune antibodies implicated in RFL are anti-nuclear antibodies (ANAs), anti-thyroid antibodies and anti-endothelial cell antibodies. The alloimmune factors implicated in pregnancy loss of unknown aetiology include abnormal natural killer (NK) cell activity, alteration in T helper 1 (Th1) and T helper 2 (Th2) ratios, presence of alloimmune antibodies like anti-paternal cytotoxic antibodies, anti-idiotypic antibodies, mixed lymphocyte reaction blocking antibodies and abnormal expression of HLA-G molecules. Management of patients with RFL is mainly based on immunomodulatory (prednisolone, intravenous immunoglobulins, plasma exchange, paternal lymphocyte therapy), anti-aggregation (aspirin) or anti-coagulation (unfractionated or low molecular weight heparin) agents. RESULTS Low-molecular-weight heparin with low-dose aspirin has been found to be the most effective treatment for women with APAs and RFL. Differences in dosage, timing of treatment, inclusion criteria, outcome assessment parameters etc. are some of the factors which have resulted in discrepancies in various reports. CONCLUSION Identification of the immunological mechanisms involved in pregnancy loss and the action of different therapeutic reagents is important so that effective therapies can be designed and investigated.

Abstract
This prospective, observational study was carried out in a teaching hospital in Calcutta, India. The aim of the study was to evaluate the prevalence of anti-phospholipid syndrome (APS) among women with recurrent miscarriages/late pregnancy loss when no other apparent causes were identified, in the study population. The women were put through a variety of investigations to determine the cause of miscarriage/pregnancy loss. Only those women who had a normal result for all the investigation went for the anti-phospholipid antibodies (APLA) test. The expelled products of conception/placenta were also sent for histopathological confirmation. A total of 445 women were studied over a 4-year period. A total of 155 women were offered a screening for APLA antibodies. Out of them, 43 women (27.7%) tested positive for APLA. Histopathological evidence was present in all the specimens. Interestingly, one woman had histopathological evidence of thrombosis, but her blood tests for the antibody were negative.

Abstract
Antiphospholipid syndrome (APS) and heparin-induced thrombocytopenia (HIT) are immune-mediated thrombotic conditions caused by antibodies targeted to a protein-antigen complex. Although each disorder is attributed to two distinct antibodies, these autoimmune disorders are characterized by a similar pathogenesis that includes a hypercoagulable state, platelet activation, damage to the vascular endothelium, and inflammation. APS and HIT share similarities in the clinical presentation because each is associated with thrombocytopenia, a high risk of thrombosis in all venous and arterial sites, and catastrophic thrombotic outcomes occur if untreated. Understanding the disease process for one disorder could potentially aid in understanding the other disorder.

Abstract
Many investigators have been intrigued by the paradoxical association of a circulating anticoagulant, first called lupus anticoagulant by Feinstein and Rapaport [1], with a tendency to develop thrombosis, as initially described by Walter Bowie [2]. Work in Leuven on this topic started when Luis Carreras, an Argentinian hematologist, joined the laboratory of blood coagulation at this university in 1979. At that time, the head of the laboratory was Marc Verstraete. Luis had a particular interest in antibody-mediated coagulation disorders, and had prepared reviews on thrombosis and thrombocytopenia induced by heparin [3] and on the lupus inhibitor [4]. In Leuven, he joined Jos Vermylen, senior member of the laboratory, and an internist with particular interest in hemostasis, thrombosis and vascular disease. As such, Professor Vermylen was involved in both laboratory research and patient care.

Abstract
Acquired thrombophilic states are common causes of thrombosis and other forms of pregnancy-associated complications. A growing body of evidence is available to guide the use of anticoagulants in patients who have antiphospholipid antibodies; unfortunately, the results of these studies are conflicting, and solid, evidence-based treatment recommendations cannot be made. Other forms of acquired thrombophilia are uncommon or of unknown clinical significance. Treatments aimed at mitigating the impacts of these states lack clear evidence to support their use.

Abstract
A 33-year-old man had systemic lupus erythematosus (SLE) with anticardiolipin antibody. At the age of 40 years, he experienced bilateral hearing deterioration. The three-dimensional fluid-attenuated inversion recovery of magnetic resonance imaging showed high signals bilaterally in the cochlea and vestibule. He was diagnosed with bilateral inner ear hemorrhage on the basis of the presence of anticardiolipin antibody. This is the first published case of inner ear hemorrhage in a patient with SLE. Our findings suggest that inner ear hemorrhage is associated with hearing deterioration in some patients with SLE.

Abstract
This article compares the manifestations of systemic lupus erythematosus (SLE) in the presence and absence of antiphospholipid antibodies (aPLs), the hallmark autoantibodies of antiphospholipid syndrome (APS). The combination of SLE and APS appears to be of greater concern than either entity alone. APS complicates SLE by adding a vaso-occlusive factor to the inflammatory component that adversely affects the prognosis of those who have lupus and aPLs. The increase in both morbidity and mortality when both are present has significant therapeutic implications. Anticoagulation may be a safer and more appropriate therapeutic option than instituting a regimen of corticosteroids and immunosuppressive agents with all their attendant adverse effects. It falls upon the physician to clearly define the disease entity and fully evaluate the disease process.

Abstract
A comprehensive literature search identified 13 randomized or quasi-randomized therapeutic trials of obstetric antiphospholipid syndrome (aPL) syndrome and all but one are appraised. Several overriding problems with trial design were evident: (i) small trial size, (ii) absence of blinding, (iii) lack of no treatment arms and (iv) highly variable entry criteria, treatments and endpoint definitions leading to trial clinical heterogeneity. Low-dose aspirin and heparin is recommended for obstetric antiphospholipid syndrome but the evidentiary basis for this remains weak. There is no evidence to support treatment with intravenous immunoglobulin or prednisone. Ideally, co-operative large fully blinded placebo controlled randomized trials of therapy in patients with obstetric aPL stratified by different levels of risk are still required.

Abstract
The endothelium is now considered a real endocrine-paracrine organ, important not only as a structural barrier between the circulation and surrounding tissue, but also because it plays an essential role for local hemodynamics, releasing substances that modulate the vascular calibre and blood cell activation. Here, after a brief but detailed analysis of the importance of the endothelium in vascular homeostasis, in the control of coagulation and in the relations with the different blood cells, we will explain the concept of endothelial dysfunction (altered NO release) and activation (amplified adhesion molecule expression) in inflammatory, connective tissue and post-trasplantation diseases. Furthermore, this review will focus on the activity of prostacyclin and synthetic analogs, especially their ability to interact with the vasodilatation system and their role in modulating cell interaction by surface adhesion molecule expression, cytokines and growth factors release as well as gene transcription factors. Finally, we will consider the therapeutic role of prostacyclin analogs in the prevention and treatment of connective tissue diseases.

Abstract
In this review, 35 cases of acute, reversible, sometimes severe, disturbances of vision closely associated with the use of celecoxib or rofecoxib are described. These were identified from three different databases using strict selection criteria. The events included temporary blindness, visual field defect, scotoma, teichopsia, blurred vision, decreased vision and abnormal vision. The reactions had a mean onset time of 9.5 days and recovery occurred within 3 days following withdrawal of the drug. The reactions do not appear to be related to age, gender, dose, or indication for use. The incidence of reported cases is estimated to be not less than 5 per 10,000 patients. Possible mechanisms for this type of reaction are described. The most likely appears to be the result of interference with the retinal blood supply through reduced production of prostanoids. Genetic polymorphisms that affect drug metabolism or uptake could be risk factors and are discussed along with suggestions for research.

Abstract
PROBLEM It is unclear whether chlamydia infection influences the miscarriage rate and immunological factors in patients with recurrent miscarriage. METHOD OF STUDY Chlamydia DNA, IgA and IgG to Chlamydia trachomatis, natural killer cell activity, complement 3 (C3), C4, hemolytic complement, antinuclear antibodies, antiphospholipid antibodies, prolactin, activated partial thromboplastin time, prothrombin time and fibrinogen were examined in 504 patients with a history of two or more consecutive first-trimester miscarriages. Subsequent pregnancy outcomes were compared between cases with and without antibodies to C. trachomatis. RESULTS Totals of 10 of 30 and 48 of 201 patients receiving no medication miscarried subsequently with and without chlamydia infection. Chlamydia IgA and/or IgG were associated with a high level of C3 but not other immunological and coagulatory parameters. CONCLUSION Antibodies to C. trachomatis do not influence subsequent pregnancy outcome in patients with a history of recurrent miscarriage.

Abstract
Twenty patients with eclampsia were studied for the presence of anticardiolipin antibodies by the standard microflocculation test (quantitative) used in the VDRL. Four out of 20 patients (20%) were positive for anticardiolipin antibodies. Anticardiolipin antibodies which are antiphospholipid antibodies by decreasing the prostacyclin production may damage the vascular endothelium and cause thrombosis in the vessels. Hence, the presence of anticardiolipin antibody in eclampsia may have association with antiphospholipid antibody syndrome described by Harris et al. (Lancet ii: 1211, 1983) and its central nervous system sequelae.

Abstract
Patients with prolonged clotting times caused by lupus anticoagulant (LAC) are at risk for thrombosis. This paradoxal association is not understood. LAC is frequently caused by anti-beta2-glycoprotein I (beta 2GPI) antibodies. Antibody-induced dimerization of beta 2GPI increases the affinity of beta 2GPI for phospholipids, explaining the observed prolonged clotting times. We constructed dimers of beta 2GPI that mimic effects of beta 2GPI-anti-beta 2GPI antibody complexes, and we studied their effects on platelet adhesion and thrombus formation in a flow system. Dimeric beta 2GPI increased platelet adhesion to collagen by 150% and increased the number of large aggregates. We also observed increased platelet adhesion to collagen when whole blood was spiked with patient-derived polyclonal anti-beta 2GPI or some, but not all, monoclonal anti-beta 2GPI antibodies with LAC activity. These effects could be abrogated by inhibition of thromboxane synthesis. A LAC-positive monoclonal anti-beta 2GPI antibody, which did not affect platelet adhesion, prevented the induced increase in platelet adhesion by beta 2GPI dimers. Furthermore, increased platelet adhesion disappeared after preincubation with receptor-associated protein, a universal inhibitor of interaction of ligands with members of the low density lipoprotein receptor family. Using co-immunoprecipitation, it was shown that dimeric beta 2GPI can interact with apolipoprotein E receptor 2 (apoER2'), a member of the low density lipoprotein receptor family present on platelets. These results demonstrate that dimeric beta 2GPI induces increased platelet adhesion and thrombus formation, which depends on activation via apoER2'.

Abstract
This review briefly describes the development of the concepts of antiphospholipid antibody and of antiphospholipid syndrome. It focuses on the two main antigenic targets, beta2 glycoprotein I and prothrombin. An excessive production of natural antibodies rather than an immune response to exogenous antigen is proposed as pathogenetic for the development of these antibodies. The review attempts to explain how some of these antibodies are anticoagulant in vitro yet prothrombotic in vivo. The final section discusses when to test for such antibodies, how to test and how to consider treatment of patients with the antiphospholipid syndrome.

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
We describe four patients with widespread cutaneous necrosis as a manifestation of the antiphospholipid antibody syndrome. In three of the patients, the lesions were the first manifestation of the syndrome, and they were located in upper and lower extremities. Vascular thrombosis was present in the skin biopsy in all of the patients. Patients were effectively treated with anticoagulants, and healing occurred within 60 days. Such widespread cutaneous necrosis is a rare manifestation of the syndrome, and it must be regarded as major thrombotic event. Long-term treatment with anticoagulants must be considered. The recognition of these lesions is important, because they may be the onset of the syndrome, allowing its early diagnosis and treatment.
