  • 32 Mechanism of Thrombosis in Antiphospholipid Syndrome: Binding to Platelets Joan-Carles Reverter and Dolors Tàssies
    32 Mechanism of Thrombosis in Antiphospholipid Syndrome: Binding to Platelets Joan-Carles Reverter and Dolors Tàssies Introduction Antiphospholipid antibodies (aPL) are related to thrombosis in the antiphospho- lipid syndrome (APS) [1, 2] and numerous pathophysiological mechanisms have been suggested involving cellular effects, plasma coagulation regulatory proteins, and fibrinolysis [3, 4]: aPL may act as blocking agents directly inhibiting antigen enzymatic or co-factor function of hemostasis; may bind fluid-phase antigens of hemostasis involved proteins and then decrease plasma antigen levels by clearance of immune complexes; may form immune complexes with their antigens that may be deposited in blood vessels causing inflammation and tissue injury; may cause dysregulation of antigen–phospholipid binding due to cross-linking of membrane bound antigens; and may trigger cell mediated events by cross-linking of antigen bound to cell surfaces or cell surface receptors [3, 4]. Moreover, several characteris- tics of the aPL, such as the concentration, class/subclass, affinity or charge, and several characteristics of the antigens, as the concentration, size, location or charge, may influence which of the theoretical autoantibody actions will occur in vivo [3]. Among the cellular mechanisms supposed to be involved, platelets have been considered as one of the most promising potential target for circulating aPL that may cause antibody mediated thrombosis as a part of the clinical spectrum of the autoimmune disorder of the APS. In the present chapter we will focus on the inter- actions that involve aPL binding to platelet membrane or platelet membrane bound antigens. Platelets as Target for aPL Platelets play a central role in primary hemostasis involving platelet adhesion to the injured blood vessel wall, followed by platelet activation, granule release, shape change, and rearrangement of the outer membrane phospholipids and proteins, transforming them into a highly efficient procoagulant surface [5].

Zineb Aouhab, MD Assistant Professor of Medicine Loyola University Medical Center 1 Division of Rheumatology Where did the word “lupus” come from? • The word ‘lupus’ is derived from the Latin word for “wolf”. • Named in the 13th century by the physician “Rogerius”. • He described the rash as erosive facial lesions as a consequence of a wolf's bite. • The facial rash is also called “Butterfly rash” because it resembles a butterfly shape. 2 What is lupus? • Lupus is an autoimmune disease. • It causes chronic inflammation in the body. • It can affect any organ of the body such as the kidneys, gastrointestinal tract, lungs, heart, and joints. 3 What happens in the body? • In normal people, the immune system forms antibodies to fight against infections. • In people with lupus, the immune system become overactive (like a bad allergic reaction) and produces a different types of antibodies. • These antibodies attack the person’s own organs causing organ damage. 4 Factors to consider in lupus • Lupus usually appears between the age of 15-45. • Lupus is much more common in females compared to males. Ratio 9:1 • Lupus is characterized by episodes of flares (when people feel very ill) and periods of remission (when people feel well and back to baseline).

    24 Lupus Anticoagulants: Mechanistic and Diagnostic Considerations Jef M. M. C. Arnout and Jos Vermylen Introduction Antiphospholipid syndrome (APS) is defined as the association of antiphospholipid antibodies (aPL) with arterial or venous thrombosis, recurrent foetal loss, thrombo- cytopenia, or neurological disorders [1–3]. The gradual development of the notion APS started in the 1950ss with the recognition of two laboratory curiosities in a subset of patients with systemic lupus erythematosus (SLE). In these patients, rheumatologists frequently found a chronic biological false positive test for syphilis, whereas hematologists described a non-specific coagulation inhibitor manifested by prolongation of the whole blood clotting time and the prothrombin time, without reduction of any specific clotting factor then measurable [1–3]. The non-specific coagulation inhibitor which appeared not to be associated with a bleeding tendency was named the “lupus anticoagulant” by Feinstein and Rapaport [4] and was regarded as a laboratory curiosity until Bowie et al [5] drew the attention to the high prevalence of thrombotic complications in SLE patients with this “anticoagu- lant.” The LA was later also found to be associated with obstetric complications and thrombocytopenia [6]. Only in the 1980s did it became clear that antibodies interacting with anionic phospholipids are responsible for the in vitro LA effect and the chronic biological false positive syphilis serology [7]. This led to the development of better-defined LA tests and the so-called anticardiolipin test in which antibodies binding to solid phase cardiolipin (aCL) are measured [8, 9]. With these improved assays, the majority of SLE patients with a LA also had elevated aCL levels and a statistically significant relation between these 2 types of aPL was observed.

  • Clinical and Laboratory Evaluation of Patients with Primary
    original Article Clinical and laboratory evaluation of patients with primary antiphospholipid syndrome according to the frequency of antinuclear antibodies (ANA Hep-2) Jozélio Freire de Carvalho1,2, Maria Teresa Correia Caleiro2, Margarete Vendramini3, Eloísa Bonfá4 ABSTRACT Objective: To evaluate the frequency of clinical and laboratory manifestations in patients with primary antiphospholipid syndrome (PAPS) with positive antinuclear antibodies (ANA Hep-2+) compared to those in whom this antibody is ne- gative (ANA Hep-2-). Patients and Methods: This is a transversal study with 58 patients (82.8% females) with PAPS. Demographic and clinical data, comorbidities, medications, and antiphospholipid antibodies were evaluated. Results: Twenty (34.5%) out of 58 patients were positive for ANA Hep-2. Comparing the group of patients ANA Hep-2+ with those that were ANA Hep-2-, it was observed that both groups of patients with APS did not show statistically significant differences regarding demographic data, as well as the duration of the disease. As for clinical and laboratorial mani- festations, the ANA Hep-2+ group showed higher frequency of deep venous thrombosis (85 versus 52.6%, P = 0.04), a statistically higher frequency of anticardiolipin IgG (85 versus 52.6%, P = 0.02), and a tendency for anticardiolipin IgM (80% versus 52.6%, P = 0.05), as well as greater medians of those antibodies [33 (0-128) versus 20 (0-120) GPL, P = 0.008] and [33 (0-120) versus 18,5 (0-120) MPL, P = 0.009]. Such difference was not observed regarding other manifestations of APS, presence of comorbidities, lifestyle, and medications used. Conclusions: Patients with PAPS with ANA Hep-2+ have a higher frequency of deep venous thrombosis and anticardiolipin IgG and IgM.
