Importance: Calciphylaxis is a rare skin disease with high morbidity and mortality that frequently affects patients with renal disease. Hypercoagulable conditions are frequently observed in both patients with calciphylaxis and those with chronic kidney disease (CKD), complicating our understanding of which hypercoagulable conditions are specific to calciphylaxis. Objective: To identify hypercoagulable conditions that are risk factors for developing calciphylaxis while controlling for CKD...

Activated Protein C Resistance is mainly associated to a factor V mutation (RQ506), which induces a deficient inactivation of activated factor V by activated protein C, and is associated to an increased risk of venous and arterial thrombosis in affected individuals, caused by the prolonged activated factor V survival. Its prevalence is mainly in Caucasians (about 5%), and this mutation is absent in Africans and Asians. Presence of Factor V-Leiden is usually evidenced with clotting methods, using a two-step APTT assay performed without or with APC: prolongation of blood coagulation time is decreased if this factor is present...

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation. Secondary hemostasis is initiated with the binding of factor VII to extravascular tissue factor (TF). Factors II, VII, IX and X are vitamin K-dependent factors. The role of vitamin K is to assist in the addition of gamma carboxylate groups to glutamic acids in the "GLA" domains of these factors...

To investigate the association of age and other factors with thrombosis risk in antiphospholipid antibody (aPL) carriers, a retrospective observational study was conducted in a cohort of patients with medium-high aPL titres recruited in a tertiary care hospital. Assuming an age difference of 9.8 years between patients with and without thrombosis, we estimated that a sample size of 70 participants was required. Several variables besides age including gender, vascular risk factors, inherited thrombophilias, non-thrombotic clinical manifestations, laboratory parameters, aPL profile, length of aPL exposure, antithrombotic drugs and partial aPL score were assessed by univariate analysis followed by multivariate logistic regression...

Anti-beta-2-glycoprotein 1 (anti-β2GP1) antibodies are associated with increased thrombotic risk in patients with autoimmune disease. There is conflicting evidence on the effects of anti-β2GP1 antibodies on platelets, with both enhanced and inhibited aggregation previously reported. However, previous studies did not include isotype antibodies to ensure the observed effects were due to anti-β2GP1 antibodies. The aims of this study were to (1) investigate the effects of anti-β2GP1 antibodies on collagen-induced platelet aggregation in parallel with negative control (buffer normal saline) and isotype control antibodies and (2) determine the lupus anticoagulant (LA) activity of anti-β2GP1 antibodies used...

BACKGROUND: Sequelae of venous thromboembolism (VTE) in children include recurrence, development of post thrombotic syndrome (PTS) when venous return from a limb is affected and chronic thromboembolic pulmonary hypertension (CTEPH) after pulmonary embolism. Identification of laboratory-based risk factors may be useful for individualized risk assessment for VTE sequelae. Coagulation activation and inflammation may contribute to their pathophysiology. We performed a systematic review to investigate the association between biomarkers of coagulation activation, inflammation and fibrinolysis and adverse VTE outcomes in children and young adults...

Neuropsychiatric systemic lupus erythematosus (NPSLE) encompasses a variety of phenomena. Manifestations are focal or diffuse, and correlate with disease mechanisms. Recent understanding of the contribution of blood-brain barrier dysfunction to the passage of circulating antineuronal antibodies into the brain parenchyma has shed light on pathogenesis. Correct attribution of neuropsychiatric manifestations to SLE remains a challenge, but validated attribution models will help. Diagnosis relies on characteristic clinical manifestations, SLE disease activity, antibody measurements, cerebrospinal fluid findings, specific neuroimaging findings, and exclusion of alternative etiologies...

PURPOSE: International consensus criteria for antiphospholipid syndrome (APS) require persistently positive antiphospholipid antibodies (aPL) and medium or high titers in association with clinical manifestations. However, the clinical relevance of persistence and titers of aPL in patients with stroke has not been identified. We aimed to investigate the risk of subsequent thrombotic events in patients with ischemic stroke with aPL positivity in terms of aPL status. MATERIALS AND METHODS: We reviewed the medical records of 99 patients with ischemic stroke with at least one or more aPL-positivity (i...

Cutaneous polyarteritis nodosa (CPAN) is a rare cutaneous small- to medium-vessel vasculitis of unknown etiology. Clinically it ranges in manifestation from livedo reticularis to large cutaneous ulcers and necrosis. Prognosis is favorable and progression to systemic polyarteritis nodosa is rare. There are multiple treatment options, none of which have proven to be definitively effective. Cutaneous polyarteritis nodosa has been associated with abnormal antibody testing with elevations of antiphospholipid cofactor antibody, lupus anticoagulant, anticardiolipin antibody, and anti-β2-glycoprotein I-dependent cardiolipin antibodies, as well as elevated anti-phosphatidylserine-prothrombin complex antibody...

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...
