The antiphospholipid syndrome is a systemic autoimmune disease dened by thrombotic or obstetrical events that occur in patients with persistent antiphospholipid antibodies. Anti-phospholipid antibodies (APLA) are a part of heterogeneous group of circulating serum polyclonal immunoglobulins (IgG, IgM, IgA or mixed) that bind negatively charged or neutral phospholipid component of cell membranes and cause increased tendency to venous or arterial thrombosis. Persistently positive APS requires that laboratory tests be conducted at least 12 weeks apart. We report a 67 years old pleasant lady presented with sudden onset dizziness, left sided weakness and right facial deviation for two days. In view of deranged aPTT and high clinical suspicion, Lupus anticoagulation tests were done using DRVVT which was prolonged. Tests were repeated after 12 weeks and Lupus anticoagulant remained positive. Routine aPTT detects upto 30% of APLAS, but DRVVT and Antibodies must be considered in such cases. This is a treatable condition, and can be prevented with long term anticoagulation. Key Message- Routine aPTT detects upto 30% of APLAS, but DRVVT and Antibodies must be considered in such cases. This is a treatable condition, and can be prevented with long term anticoagulation.

Antiphospholipid syndrome (APS) is an autoimmune disease characterized by venous thromboembolism, arterial thrombosis, and obstetric morbidities in the setting of persistently positive levels of antiphospholipid antibodies. It may be primary or secondary. The latest classification criteria (Sydney 2006) recognize just three tests to define this syndrome- lupus anticoagulant, anticardiolipin antibodies and anti-?2-glycoprotein-1 antibodies. Treatment of thrombotic events involves lifelong anticoagulation with vitamin K antagonist warfarin. Antiphospholipid antibody syndrome (APS) with only pregnancy morbidity is treated with thromboprophylaxis with heparin during pregnancy and postpartum for 6 weeks. In this review we discuss the pathogenesis, diagnosis, treatment and prognosis of the APS.

Antiphospholipid Antibody Syndrome (APS) is a highly prevalent cause of antibody-mediated thrombosis manifesting in venous thrombosis (DVT and PE), arterial thrombosis (most commonly stroke), and pregnancy complications. The diagnosis of definite APS requires both clinical and laboratory criterion as established by the working group of the International Congress on Antiphospholipid Antibodies (based on expert opinion). Since thrombosis and pregnancy loss are common in the general population, and antiphospholipid antibodies (aPL) occurs in a small percentage of the healthy public, it is important to demonstrate antibody persistence in patients who have the proper clinical indications in order to avoid misdiagnosis. Unfortunately, laboratory testing in this area lacks standardization, resulting in wide inter-laboratory variance. However, due to the commercialization of tests and automation, inter-laboratory variance has improved. Data on several new non-criterion tests suggest that they may improve the specificity or risk stratification for thrombosis. A new guidance document on aPL testing strives to achieve better consistency, but much work remains to be done in the area of standardization.

SummaryObjective: To evaluate the usefulness of IgA antiphospholipid antibodies as markers of thrombosis and/or antiphospholipid antibody syndrome. Patients and Methods: A cross-sectional study design in a tertiary, university-based, autoimmune reference hospital. Seven-hundred ninety-five patients classified into five different groups – autoimmune diseases (255), deep vein thrombosis (153), transitory ischemic attacks (108), obstetric complications (196), infectious diseases (83) and controls (81) – were tested for IgA, IgG and IgM aPL, and lupus anticoagulant. Plasma and serum samples were drawn for detection of aPL using an internationally standardized ELISA method and LA was carried out using coagulometric assays. Results: True IgA aPL were found only in two patients with systemic lupus erythematosus; these patients were also positive to IgG aPL. Conclusion: The incidence of true positivity to IgA anticardiolipin antibodies is extremely low. Their determination was not helpful in diagnosing the antiphospholipid syndrome or in explaining thrombotic events or aPL related manifestations – fetal loss – in the groups studied.

Antiphospholipid antibody syndrome is an autoimmune disease characterized by thrombosis, both arterial andvenous, recurrent spontaneous abortion and the persistence of positive antiphospholipid antibodies. Placentalthrombosis is believed to be the cause of recurrent abortions, characteristic of the syndrome. We report a pregnantwith antiphospholipid antibody syndrome patient with history of recurrent miscarriages and managed successfullywith high dose heparin.Keywords: Antiphospholipid antibody syndrome; recurrent intra uterine death; HeparinDOI: 10.3329/jom.v11i2.5476J MEDICINE 2010; 11 : 205-206

AbstractAntiphospholipid antibody syndrome (APS) is a systemic, autoimmune, prothrombotic disease characterized by persistent antiphospholipid antibodies (aPLs), thrombosis, recurrent abortion, complications during pregnancy, and occasionally thrombocytopenia. The objective of the present study was to review the pathophysiology of APS and its association with female infertility. A bibliographic review of articles of the past 20 years was performed at the PubMed, Scielo, and Bireme databases. Antiphospholipid antibody syndrome may be associated with primary infertility, interfering with endometrial decidualization and with decreased ovarian reserve. Antiphospholipid antibodies also have direct negative effects on placentation, when they bind to the trophoblast, reducing their capacity for invasion, and proinflammatory effects, such as complement activation and neutrophil recruitment, contributing to placental insufficiency, restricted intrauterine growth, and fetal loss. In relation to thrombosis, APS results in a diffuse thrombotic diathesis, with global and diffuse dysregulation of the homeostatic balance. Knowing the pathophysiology of APS, which is closely linked to female infertility, is essential for new therapeutic approaches, specialized in immunomodulation and inflammatory signaling pathways, to provide important advances in its treatment.

AbstractAntiphospholipid antibody syndrome (APS), a hypercoagulable state, affects organ by causing venous or arterial thrombosis. We present an unusual case of a 58-year-old male who presented with diffuse abdominal pain and on evaluation diagnosed as having portomesenteric venous thrombosis due to primary APS. Upon successful treatment with enoxaparin followed by anticoagulants for 6 months, recanalization of the portal vein was documented by endoscopic ultrasonography. Early identification and treatment of portomesenteric thrombosis is crucial to prevent bowel ischemia. Lifelong anticoagulation with vitamin K antagonists should be considered in those patients with major thrombosis and established APS.

Background Antiphospholipid antibody syndrome (APS) is an autoimmune disease that affects women in childbearing age. In recent years, great improvements were achieved in the management of pregnancies in these women. Prematurity could be an issue in these pregnancies, mainly due to the direct pathogenic effect of antiphospholipid antibodies (aPL) on the placental surface. Maternal IgG aPL can cross the placenta and theoretically interact with the growing fetus; it could reach the fetal brain because of the incompleteness of the fetal blood-brain barrier: whether this can have an effect on brain development is still debated. Neonatal thrombosis episodes have been described in children positive for aPL, not always associated with maternal antibody positivity, suggesting the hypothesis of a possible aPL de novo synthesis in fetus and neonates. Methods A keyword-based literature search was conducted. We also described a case of neonatal catastrophic antiphospholipid syndrome (CAPS). Results Offspring of patients with APS are generally healthy but the occurrence of neonatal thrombosis or minor neurological disorders were reported. Conclusions The limited number of the available data on this sensitive issue supports the need for further studies. Clinical follow-up of children of mothers with APS seems to be important to exclude, in the neonatal period, the occurrence of aPL associated pathological events such as thrombosis, and in the long-term, impairment in learning skills or behavioral problems.
