Lupus anticoagulants (LA) are acquired inhibitors of coagulation related to the antiphospholipid antibodies. Paradoxically, these anticoagulants do not expose patients to the risk of hemorrhage but, on the contrary, to a thrombotic risk. The association in a patient of an antiphospholipid antibody and a clinical manifestation (thrombosis or equivalent) defines the antiphospholipid syndrome. This syndrome is termed primary or secondary according to whether it appears as an isolated disorder or is associated with an identified disease, frequently autoimmune (systemic lupus erythematous or lupus related syndrome). Clinical complications of LA are arterial or venous thrombosis at various sites. They are frequently recurrent, and deep venous thrombosis of leg, oculo-cerebral ischemic lesions and heart valve complications have all been well documented. Thrombosis of the microcirculation can cause tissue or organ disfunction, the most characteristic effect being repeated abortions. Laboratory demonstration of LA is difficult when the inhibitor is weak, and this should be completed by tests for other antiphospholipid antibodies. Clinical studies are necessary to assess the thrombotic risk of the LA in different clinical conditions and to evaluate the need and type of antithrombotic treatment. The LA are heterogeneous and only a small proportion of patients with LA will develop thrombosis. New tests capable of predicting the thrombotic risk, bases on the physiopathological mechanisms with which LA interfere in vivo, are currently being investigated.

Antiphospholipid syndrome (APS) is an entity characterized by recurrent thrombotic events and may occur spontaneously or in the context of systemic lupus erythematosus (SLE). We describe an English Canadian family in whom the propositus, a woman with Graves' disease and SLE, was found to have a lupus anticoagulant and anticardiolipin antibody (aCL). A brother with deep vein thrombosis, pulmonary emboli, bilateral adrenal hemorrhage and thrombocytopenia, circulating anticoagulant and aCL had a positive antinuclear antibody and Coombs' test, but no other features of SLE. Fourteen members of 3 generations of this family underwent clinical assessments, serological testing and HLA typing. The propositus' mother had a family history of autoimmune thyroid disease and the father had aCL, but was asymptomatic. The thyroid disease and the SLE were associated with HLA-B8, DR3 haplotype. The aCL and the anticoagulant were associated with HLA-B60, DR4 haplotype. Both these haplotypes were present in the propositus. Among the other 4 carriers of the haplotype B60, DR4, 3 demonstrated significant titers of aCL. Our findings support the reported association between APS and the HLA haplotype DR4 in patients of English descent with SLE.

Antiphospholipid antibodies (APA) have been described not only in systemic lupus erythematosus but also in several inflammatory diseases of the connective tissue, some infections, neoplasms, in pregnancy and even in apparently healthy individuals. Arterial and venous thrombosis are some of the clinical manifestations most frequently associated with APA. Two patients with ankylosing spondylitis with antiphospholipid antibodies are presented. The first patient developed a infarct in the pons as a complication at 34 years of age, with high titres of anticardiolipin antibodies as the only factor predisposing a cerebral vascular accident. The second patient had deep vein thrombosis with the presence of circulating anticoagulant. These are the first cases of antiphospholipid syndrome associated to ankylosing spondylitis in the literature.

A previously healthy 16-year-old girl complaining of fever, hemosputum, chest pain and dyspnea was hospitalized. On admission, physical examination revealed mental confusion, holosystolic heart murmur, and swelling of the left foot. Laboratory investigations showed anemia, leukocytosis, thrombocytopenia, activation of inflammatory reactions, prolongation of PT and APTT, and hypoxia. Antinuclear antibody test was negative. There were no other findings suggestive of collagen diseases such as SLE. Chest X-ray showed consolidation in the left lower lung field and pleural effusion. Echocardiography disclosed a mass lesion in the left atrium in contact with the mitral valve, and mitral regurgitation. No findings indicative of an infectious etiology were present. The patient rapidly improved with high dose corticosteroid and anticoagulant therapy. A venogram of the lower extremity disclosed deep venous thrombosis. A lung ventilation-perfusion scan revealed multiple pulmonary thromboemboli. Elevation of anticardiolipin antibody was noted. Based on these findings, the diagnosis of primary antiphospholipid syndrome was made. Further administration of steroid and anticoagulant resulted in decrease of the titer of anticardiolipin antibody. This is the second report of primary antiphospholipid syndrome in Japan. The clinical significance of this disease is also discussed.

We describe a 35-year-old man with a history of previous deep vein thrombosis who presented with hypertension. Renal investigations revealed failure to excrete contrast medium by the right kidney on intravenous pyelography. Digital subtraction angiography showed an 80% stenosis of the left renal artery. He was antinuclear antibody negative, as well as negative for antibodies to double stranded deoxyribonucleic acid and extractable nuclear antigens. The lupus anticoagulant test and antibodies to cardiolipin were positive. He conforms to a diagnosis of "primary" antiphospholipid syndrome.

A 30-year-old man presented with an episode of deep vein thrombosis. He was found to have primary antiphospholipid syndrome with anticardiolipin antibodies and protein S deficiency. All other investigations were negative. Three months later, anticardiolipin antibodies were negative and protein S levels were normal. The transient presence of anticardiolipin antibodies and functional protein S deficiency in this patient suggests a new mechanism for the association between anticardiolipin antibodies and venous thrombosis.

Two cases of primary antiphospholipid syndrome are described. A girl presented with myocardial infarction at the age of 6. afterward developed chorea, livedo reticularis, thrombocytopenia and circulating lupus anticoagulant (LAC). A boy, age 7, had an episode of intracranial hypertension and a deep venous thrombosis of a lower left limb, both recurrent in the following years. A high titer of IgG anticardiolipin antibodies (aCI) was detected. These observations suggest that both LAC and aCI tests should be performed in children with thromboembolic phenomena when the criteria for a definite autoimmune disease are lacking.

The clinical and serological findings in 13 patients with myocardial infarction and antiphospholipid antibodies (the 'lupus anticoagulant', antibodies to cardiolipin, antibodies to phosphatidylethanolamine (one patient] seen by our unit and other units from 1984 to 1989, are presented (eight males and five females, ages ranging from 20 to 52 years). Five suffered myocardial infarction before the age of 30; four of these five were in their early 20s. Other risk factors such as excessive smoking (greater than 20 cigarettes a day) (two patients), long-term treatment with steroid (one) and use of oral contraceptives (one) were present. One patient had demonstrated a plasminogen activator deficiency and one a deficiency of protein C. Two patients developed myocardial infarction six to eight weeks after warfarin was discontinued for recurrent deep vein thrombosis. Six patients had SLE as defined by the revised 1982 criteria, three suffered from 'lupus-like' disease, while four patients conformed to a 'primary' antiphospholipid syndrome.

The authors report the case of a 10 year old child who presented with an uncomplicated deep venous thrombosis associated with an antiphospholipid syndrome. The diagnosis was established by the finding of spontaneous prolongation of the activated cephalin time, the finding of a lupus-like antibody and an anti-cardiolipin antibody. The clinical outcome was good with oral anticoagulants but a recurrence was observed when they were stopped. The authors discuss the question of the duration of preventive therapy.

A 23-year-old man was admitted because of an attack of chest pain and dry cough. Chest roentogenogram showed a solitary pulmonary nodule in the left upper lobe. Chest CT showed a nodule and a small pleural effusion on the same side. Pulmonary thrombosis was diagnosed by pulmonary Ventilation/perfusion scintigraphy and pulmonary arteriography. Deep vein thrombosis was not detected except in a distal pulmonary artery. The solitary nodule disappeared spontaneously without thrombolytic therapy. An anticardiolipin antibody (IgG) test was positive. Primary antiphospholipid syndrome was diagnosed, because of the absence of physical findings suggesting other collagen vascular diseases. Patients with antiphospholipid syndrome have a high frequency of pulmonary complications that include pulmonary hypertension and pulmonary embolism. Most of the patients with pulmonary embolism have deep vein thrombosis, and pulmonary vessel thrombosis as seen in the present case is a rare complication.
