lupic anticoagulant

Cristiana Carvalho, Carolina Viveiro, Paulo Maia, Teresa Rezende
Acquired inhibitors of coagulation causing bleeding manifestations are rare in children. They emerge, normally in the context of autoimmune diseases or drug ingestion, but transient and self-limiting cases can occur after viral infection. We describe, an otherwise healthy, 7-year-old girl who had gingival bleeding after a tooth extraction. The prothrombin time (PT) and the activated partial thromboplastin time (APTT) were both prolonged with evidence of an immediate acting inhibitor (lupic anticoagulant). Further coagulation studies demonstrated prothrombin (FII) deficiency and prothrombin directed (FII) antibodies...

A 28-year-old, hypertensive and hypercholesterolaemic patient, was referred to our emergency unit with a mild thoracic pain, productive cough and a body temperature of 37.3°C. Laboratory examinations showed normal white cell count and moderate elevation of C reactive protein (CRP). Later, the thoracic pain increased accompanied by shortness of breath. High D-dimer was detected. Positive lupic anticoagulant factor and anticardiolipin and antibodies anti-Mycoplasma pneumoniae were present and high titres of antinuclear factor...

This case report concerns a 40-year-old patient with an unspecific abdominal pain, diarrhoea, a big axillary mass and a previous pulmonary infection. After biopsy of the axillary mass the diagnosis of lymphoma was excluded based on the presence of cells expressing polyclonal antibodies. Abdominal CT scans and angionuclear magnetic resonance showed an extensive intestinal venous thrombosis. The patient also presented positive results for C and S proteins, lupic anticoagulant factor and antiphospholipid antibodies (anticardiolipin antibodies - IgM and IgG)...

Spinal epidural hematoma (SEH) is a rare acute condition defined as a hematoma occurring at spinal epidural level. It is defined as "spontaneous" (SSEH) when possible causes have been ruled out; in other cases, clotting disorders and systemic lupus erythematosus have been associated with SEH. If identified rapidly, SEH can be completely cured, with complete recovery in about 50% of cases. We describe the case of an 86-year-old man affected by SEH, with rare anterior location, presenting with painful paraparesis and bladder dysfunction...

We present the case of a 75-year-old man who was diagnosed with Degos disease (DD) in the context of type 2 diabetes mellitus. The cutaneous lesions of DD were located at the trunk as well as in the proximal parts of the arms. He presented with positive laboratory test for lupic anticoagulant, but other rheumatologic parameters of interest were within normal limits. The skin biopsy corroborated the diagnosis of DD, and also showed morphologic features traditionally associated to hyaline diabetic microangiopathy...

Recurrent pregnancy loss is secondary to multiple illnesses. An important cause sometimes undiagnosed is the antiphospholipid syndrome, an autoimmune disease with various clinical alterations (miscarriage, hypertensive disorders, preterm delivery, vascular thrombosis, intrauterine retard growth, death intrauterine, abruption placentae). There are major and minor clinical criteria and precise indications that guide the physician to its recognition. Antibodies related with the syndrome are anticardiolipin and lupic anticoagulant, but other phospholipids seems to be implicated on this pathology and its participation on trombotic events is even unknown...

A 33 years old woman was admitted to the hospital after four days with cough, dyspnea, orthopnea and hemoptysis. Blood pressure was 170/90 mmHg, pulse was 112 and temperature was normal. She had cyanosis and a left ventricular gallop, without heart murmurs. A chest radiograph revealed pulmonary edema and echocardiogram showed a global left ventricular systolic disfunction. Oxygen and furosemide were started, but cardiopulmonary collapse ensued. The patient was supported with mechanical ventilation and treated with inotropic drugs...

The antiphospholipid syndrome (APS) was defined 20 years ago by Hughes as a thrombosis (arterial and/or venous) state and/or recurrent pregnancy loss in the presence of antiphospholipid antibodies like lupic anticoagulant and/or anticardiolipin, which sometimes coexist with thrombocytopenia. Although the prevalence of APS is estimated to be 3 to 200 cases per 100,000 inhabitants, many cases remain without a proper diagnosis. Recurrent thrombosis events can happen at any site in the vascular tree, yet most common affected sites are deep veins and cerebral arteries...

INTRODUCTION: As a chronic chagasic myocardiopathy, Chagas disease (CD) may give rise to cardiac insufficiency, arrhythmias, thromboembolism and stroke. Occlusive vascular disease of the rostral portion of the basilar artery or of its emergent branches may cause ischemia and necrosis in different areas of the midbrain, thalamic nuclei, cerebellum and occipital lobe. CASE REPORTS: We describe four patients (three males and a female, the average age being 54 years) with positive chagasic serology (indirect immunofluorescence and hemagglutination) and suffering from CD and top of the basilar syndrome...

The human immunodeficiency virus (HIV) infection is becoming more complex. Hemostatic abnormalities occur frequently in the patient with HIV. HIV-related thrombocytopenia (Tr-HIV) is the most common hemostatic disorder with a high morbidity and affects patients from every risk group independently of age, sex, or stage of infection. Two mechanisms are responsible for the Tr-HIV: bone marrow failure and immunological disorders, namely, circulating immune complex deposited on the platelet membrane and the production of autoantibodies directed against platelets...

Results obtained in three patients with juvenile ischemic stroke and criteria of primary antiphospholipid syndrome is reported. These patients are selected out from a series of 12 patients with 18-mounts follow-up. Lupic anticoagulant and anticardiolipin antibodies were found in two of three patients and one patient show anticardiolipin antibodies with negative lupic anticoagulant. All others coagulation proteins examined (antithrombin III, plasminogen, protein C and protein S) were normal. We conclude that antiphospholipid antibodies are associated with increase risk of thrombosis...

Six women, aged 16 to 27 years old at the beginning of their illness suffered recurrent spontaneous abortion (two to eight episodes) and three of them had arteriolar venous thrombosis. These symptoms led to the finding of an antiprothrombinase type of circulating anticoagulant. In two cases, positive dissociated syphilitic serology was observed and all patients presented other haematological abnormalities: thrombocytopaenia and/or autoimmune haemolysis. The diagnosis of disseminated lupus erythematosis was established after an average period of 11 years (range 1 to 27 years) based on at least 4 of the ARA criteria (five out of six cases) and/or characteristic immunological abnormalities (five out of six cases)...

Circulating anticoagulant was detected during the course of choreic manifestations in three young women with systemic lupus erythematosus, associated in two cases with false syphilitic serology due to the presence of antiphospholipid antibodies. The high prevalence of the presence of these antibodies in lupic chorea was confirmed by reports of 41 cases in the literature. These findings could suggest a possible pathogenic role for these antibodies in choreic manifestations by either a thrombotic or auto-immune encephalitis mechanism...

Anatomical studies have demonstrated the high incidence of vasculitis in SLE, the appearances of which are variable and non-specific, ranging from necrotizing angiitis which is undistinguishable from periarteritis nodosa, to scarring lesions. Micro-angiitis is easily demonstrated in skin lesions and is also encountered to varying degrees in CNS, renal, cardiac, pulmonary and gastrointestinal localisations. Disease of large vessels is more rare and sometimes causes gangrene of the limbs. In SLE, vasculitis should be distinguished from thrombosis related to lupus anticoagulant and from atherosclerosis favoured by chronic steroid therapy but perhaps initiated by vascular deposits of immune complexes during the acute inflammatory stage...

BACKGROUND: The aim of this study was to know the prevalence and characteristics of endothelial anticellular antibodies (EAA) in systemic lupus erythematosus and its relation with the clinical and immunologic manifestations of this entity. METHODS: A prospective study of 50 patients (44 females and 6 males) diagnosed with SLE was carried out. EAA and anticardiolipin antibodies (ACA) were determined by the ELISA technique, lupic anticoagulant by coagulometric techniques, antinuclear antibodies by indirect immunofluorescence, anti-DNA antibodies by the Farr technique, anti-ENA by contra-immunoelectrophoresis and the complement values by radial immunodiffusion...
