Antiphospholipid syndrome (APS) is an autoimmune disease that is characterized by arterial and/or venous thrombosis and/or recurrent pregnancy losses. Obstetric APS (OAPS) is considered as a distinct entity from vascular APS (VAPS). In the absence of any additional disease, APS is designated as primary (PAPS), while the term secondary APS (SAPS) is used when other diseases are associated. Catastrophic APS (CAPS) is characterized by the rapid development of multiple thrombosis in various vital organs. The presence of antiphospholipid antibodies (aPL Abs) is considered as a laboratory criterion for APS diagnosis...

BACKGROUND: Antiphospholipid antibodies (aPL) contribute to the pathogenesis of the antiphospholipid syndrome (APS) by induction of an inflammatory and procoagulant state in different cell types and several signaling pathways have been described. OBJECTIVES: We hypothesized that signaling depends on epitope specificity of aPL. METHODS: Cellular effects of three human monoclonal aPL with distinctly different epitope specificities were analyzed in vitro...

PROBLEM: To examine whether the level of plasma D-dimer can guide anticoagulant treatment in recurrent pregnancy loss (RPL) associated with antiphospholipid syndrome (APS). METHODS: A total of 1096 RPL women with APS between 2012 and 2015 in a single-center hospital were randomly divided into two groups (group A, 75 mg of low-dose aspirin [LDA] daily; group B, 75 mg of LDA plus 4100 U of low molecular weight heparin [LMWH] subcutaneously daily); 1015 of the total successfully completed the trial...

Diffuse alveolar hemorrhage (DAH) is a rare but potentially fatal complication in systemic lupus erythematosus (SLE). DAH is typically characterized by hemoptysis, dyspnea, new infiltrates on chest x-rays or CT-scans and a drop in hemoglobin. DAH is seen in less than 2% of patients with SLE and carries a high acute mortality risk of up to 70-90%. The current treatment of DAH is high-dose intravenous corticosteroids, cyclophosphamide and extensive supportive care. Plasmapheresis is also often considered in the treatment...

INTRODUCTION: Generaly, natural killer cells (NK cells) are among the most important cells of our immune defense system. They are present in the blood, decidua but also in secretory endometrium. OBJECTIVE: We investigate an association between high density of NK cells CD56+ and NK cells CD16+ into blood and secretory endometrium in patients with up to now unexplained recurrent miscarriage. At the same time, we focused on diagnosis of antiphospholipid syndrome, congenital trombophilic factors, stress factor, and lenght of hormonal contraception before conception...

OBJECTIVES: To assess the rate of anomalies in the etiological evaluation of patients presenting recurrent early miscarriages (RM) according to miscarriage chronology (number of miscarriages, history of live birth and succession of RM). METHODS: Retrospective single centre study including RM, defined as at least 2 miscarriages at less than 14 weeks of gestation (WG) between the 1(st) January 2012 and the 31(st) December 2015. Clinical data and etiological evaluation include blood glucose levels, screening for antiphospholipid syndrome (APS), endocrine assessment, vitamin levels, pelvic imaging, karyotyping of both partners, chronic endometritis and thrombophilia screening...

Antiphospholipid syndrome (APS) is an autoimmune condition that is associated with thrombosis and morbidity in pregnancy. The exact mechanisms by which these associations occur appear to be heterogeneous and are not yet well understood. The aim of this study was to identify and analyze publications in recent years to better understand the diagnosis and its contribution to monitoring APS among women with recurrent miscarriage (RM). This systematic review and meta-analysis was conducted using the PubMed and Web of Knowledge databases, with articles published between 2010 and 2014, according to the PRISMA statement...

Native aortic valve thrombosis in primary antiphospholipid syndrome (APLS) is a rare entity. We describe a 38-year-old man who presented with neurological symptoms and a cardiac murmur. Transthoracic echocardiography detected a large bicuspid aortic valve thrombus. Laboratory evaluation showed the presence of antiphospholipid antibodies. Anticoagulation was started, and serial echocardiographic studies showed complete resolution of the aortic valve vegetation after 4 months. The patient improved clinically and had no residual symptoms...

Children with systemic lupus erythematosus (SLE) generally undergo a pretreatment kidney biopsy. However, some of these patients, especially those with antiphospholipid syndrome (APS), may experience serious coagulopathic complications. We report herein two cases of paediatric SLE with APS in which, despite normal blood test results, the disparate coagulopathic complications of haemorrhage and embolism developed following a kidney biopsy. Case 1 was, an 8-year-old male in whom, primary APS was initially diagnosed...

BACKGROUND: Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by arterial or venous thrombosis (or both) and/or pregnancy morbidity in association with the presence of antiphospholipid antibodies. The prevalence is estimated at 40 to 50 cases per 100,000 people. The most common sites of thrombosis are cerebral arteries and deep veins of the lower limbs. People with a definite APS diagnosis have an increased lifetime risk of recurrent thrombotic events. OBJECTIVES: To assess the effects of antiplatelet or anticoagulant agents, or both, for the secondary prevention of recurrent thrombosis, particularly ischemic stroke, in people with antiphospholipid syndrome...

Mounting evidence suggests a connection between human parvovirus B19 (B19) and autoimmune diseases, and especially an association between the B19-VP1 unique region (VP1u) and antiphospholipid syndrome (APS). However, little is known about the antigenicity of B19-VP1u in the induction of APS-like syndrome. To elucidate the antigenicity of B19-VP1u in the induction of APS, N-terminal truncated B19-VP1u (tVP1u) proteins were prepared to immunize Balb/c mice to generate antibodies against B19-tVP1u proteins. The secreted phospholipase A2 (sPLA2) activities and binding specificity of mice anti-B19-tVP1u antibodies with cardiolipin (CL) and beta-2-glycoprotein I (β2GPI) were evaluated by performing immunoblot, ELISA and absorption experiments...

INTRODUCTION: The relevant literature includes several case reports on cerebral infarction in children with HHV-6 infection; however, there is no report of brain stem infarction. CASE: An 11-month-old girl was hospitalized because of fever. She was unable to stand up and meet her mother's gaze. Magnetic resonance imaging (MRI) indicated a right pons and mid-brain lesion; a diagnosis of brainstem infarction was made. After her fever subsided, a rash developed on her trunk and limbs; blood examination results indicated a primary HHV-6 infection...

Interstitial lung diseases are not infrequently complicated by development of malignancies and whilst most cases are carcinomas, rare cases of lymphoma have been reported,(1 2) these being diffuse large B-cell lymphomas and often associated with connective tissue disorders (CTDs). Reactive pulmonary lymphoid hyperplasia (RPLH), typically in the form of lymphoid interstitial pneumonia (LIP) often arises in patients with CTDs and only rarely shows malignant transformation,(3) with many of the early putative cases of transformation to MALT (mucosa-associated lymphoid tissue) lymphoma from LIP being lymphoma 'de novo'...

Antiphospholipid (aPL) antibodies are antibodies specific for anionic phospholipids. They are immunoglobulins that attack phospholipids, phospholipid-binding proteins, or phospholipid-protein complexes and are detected in anticardiolipin and lupus anticoagulant assays. aPL antibodies are often associated with antiphospholipid syndrome (APS) which can be idiopathic or from secondary causes such as systemic lupus erythematosus (SLE), infection or drugs. They have also been shown to be associated with Pulmonary Hypertension...

Methods Patients fulfilling the ACR and/or the SLICC classification criteria for SLE were enrolled at inception and followed-up to 10 years at an academic lupus clinic. Damage was defined as SLICC Damage Index (SDI) score ≥1. We assessed with multivariate Cox models the damage and mortality outcomes, according to SLE classification status at inception, adjusting for potential baseline confounders...
