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...

Domain I (DI) of beta-2-glycoprotein I (β2GPI) contains the immunodominant epitope for pathogenic antiphospholipid antibodies (aPL). DI is exposed in the linear form of the molecule but not in the circular form that comprises 90% of serum β2GPI. The majority of circulating β2GPI is biochemically reduced with two free thiols in Domain V. However, increased levels of oxidised β2GPI are found in patients with antiphospholipid syndrome (APS). It is not known whether oxidation of β2GPI favours the linear form of the molecule and thus promotes development of anti-DI antibodies...

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...

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...

Natural IgM autoantibodies have been proposed to convey protection from autoimmune pathogenesis. Herein, we investigated the IgM responses in 396 systemic lupus erythematosus (SLE) patients, divided into subgroups based on distinct autoantibody profiles. Depressed IgM levels were more common in SLE than in matched population controls. Strikingly, an autoreactivity profile defined by IgG anti-Ro/La was associated with reduced levels of specific natural IgM targeting phosphorylcholine (PC) antigens and malondialdehyde (MDA) modified-protein, as well as total IgM, while no differences were detected in SLE patients with an autoreactivity profile defined by anti-cardiolipin/β2glycoprotein-I...

BACKGROUND: Sickle cell anemia (SCA) is characterized by abnormally shaped, adhesive RBCs that interact with white blood cells and the endothelium, leading to chronic hemolysis, vasculopathy and a prothrombotic state. About 10% of subjects with a thrombotic event in the general population will have an associated antiphospholipid (aPL) antibody. One proposed mechanism for the thrombophilic nature of aPL antibodies is the disruption of the potent anticoagulant annexin A5 or Annexin A5 resistance (A5R)...

Anti-phospholipid syndrome is a complex and severe clinical situation, associated with symptoms such as recurrent thrombosis, arterial or venous, at any site, pregnancy loss, and other related syndromes. These clinical burdens, are highly variable from patient to patient, and are associated with biological abnormalities, such as the presence of the Lupus Anticoagulant or phospholipid dependent antibodies, confirmed on two occasions at least 12 weeks apart. From the diagnosis standpoint, both, functional (clotting) or immunological assays, are difficult to standardize and to optimize, due to the absence of reference material, or a characteristic clinical group, and international reference preparations...

Autoimmune pathogenesis is responsible for a subset of primary ovarian insufficiency (POI) cases. The significance of autoantibodies for POI, however, remains unclear. A total of 250 women with idiopathic POI and 256 age-matched healthy women were enrolled. The presence in serum of adrenal cortex autoantibody (AAA), detected by indirect immunofluorescence and non-organ-specific antibodies, including antinuclear antibody, anti-cardiolipin antibody, and anti-double stranded DNA antibody, detected by enzyme-linked immunosorbent assay, was compared...

Antiphospholipid Syndrome (APS) is an autoimmune disorder with clinical and laboratory features of vascular thrombosis, pregnancy loss, and persistent antiphospholipid antibodies (aPLs). The pathophysiology is thought to involve the activation of endothelial cells, monocytes, platelets, and complement by aPLs. Disease can range from asymptomatic to rapidly fatal catastrophic APS. We present a case of a 34-year-old male referred for pancytopenia and splenomegaly. On examination, he had decreased sensation and 4/5 power in the left upper extremity...

The cellular immune response to Mycobacterium tuberculosis infection has been well characterized, while the humoral antibody response remains underexplored. We aimed to examine the total and anti-phospholipid IgM levels in the pleural lavage from mice with Mycobacterium bovis BCG extrapulmonary infection. We found that the levels of total and anti-phosphatidylcholine IgM antibodies remained significantly higher in infected mice as compared to non-infected mice up to day 90 after BCG infection, while the anti-cardiolipin IgM antibody levels decreased with bacteria clearance...

Catastrophic antiphospholipid syndrome (CAPS) is a severe variant of APS, characterised by clinical evidence of multiple organ involvement developing over a very short period of time, histopathological evidence of multiple small vessel occlusions and laboratory confirmation of the presence of aPL (lupus anticoagulant and/or anticardiolipin antibodies and/or anti-Beta2-glcyoprotein I antibodies). Here we report a case of a 39-year-old woman patient who developed a CAPS which was negative to the conventional aPL but positive for aPL in thin layer chromatography immunostaining and vimentin/cardiolipin antibodies by ELISA test...

We report a case of cerebral venous thrombosis related to the ingestion of tadalafil. A 45-year-old man presented with posterior headache and was diagnosed with tension headache. Five days later, he was transported to our hospital via ambulance due to a tonic-clonic seizure. Head MRI showed cerebral venous thrombosis (CVT). He confessed to having recently taken a large doses of tadalafil. His anti-cardiolipin antibody and anti-caldiolipin-β2-glycoprotein-I complex antibody levels were elevated. Our case suggests the possibility that tadalafil is related to both cardiovascular complications and CVT in patients with hypercoagulability...

BACKGROUND: Superficial vein thrombosis (SVT) is a common venous condition. Recent studies have shown that SVT is associated with high frequency of thromboembolic complications: from 22-37% for deep venous thrombosis and up to 33% for pulmonary embolism. Our goal was to assess the prevalence of major hereditary and acquired thrombophilic factors in patients with SVT. METHODS: Sixty-six patients presenting with primary SVT underwent evaluation for thrombophilia: molecular testing for the factor V Leiden and factor II G20210 A (prothrombin) mutations, protein C, protein S, antithrombin deficiency, presence of lupus anticoagulant, as well as anticardiolipin antibody titers...
