We describe a 36-year-old man with antiphospholipid antibody syndrome complicated by cerebral hemorrhage. In December 1991 he was brought to another hospital with sudden onset of left hemiparesis and status epilepticus. He had been well previously. A CT scan and MRI showed a cerebral hematoma located in the right frontoparietal region. Twelve days later he was transferred to our hospital. Altho...

Antiphospholipid antibody (aPL) is a heterogeneous group of autoantibodies directed against phospholipids-binding proteins. Antiphospholipid syndrome (APS) is defined by two major components: 1) presence of at least one type of aPLs, 2) the occurrence of at least one clinical feature from a list of potential disease manifestations, the most common of which are categorized as venous or arterial ...

OBJECTIVE The Sydney classification criteria for antiphospholipid syndrome include lupus anticoagulant or moderate-to-high titre anticardiolipin IgG or IgM. We explored the association of all anticardiolipin isotypes, lupus anticoagulant and the combination with venous and arterial thrombosis. METHODS Patients with systemic lupus erythematosus (SLE) in a large clinical cohort seen quarterly w...

Polyclonal anticardiolipin antibodies purified from pooled serum samples of patients with systemic lupus erythematosus were shown to have inhibitory effects on cultured normal rat brain astrocytes (RBA-1 cells). Anticardiolipin antibodies at concentrations from 50 to 200 micrograms/ml inhibited the [3H]thymidine incorporation of RBA-1 cells in a dose dependent manner after three days of culture...

An 18-year-old male presented with a nonhealing wound on left lower limb, pain and swelling over multiple joints, weight loss, and yellowish discoloration of eyes and urine for the past 4 years. On examination, the patient had pallor, icterus, and generalized lymphadenopathy with a nonhealing unhealthy ulcer over left medial malleolus. He had deformed joints with hepatomegaly and splenomegaly. ...

In order to determine the role of different anti-phospholipid antibodies as an etiologic factor in recurrent pregnancy failure, a prospective study was done on one-hundred and thirty-eight women who had unexplained recurrent pregnancy loss (group I) with one-hundred well-matched women with normal reproductive outcome allocated as control group (GIl). Sera from 138 patients and 100 controls...

Anticardiolipin antibodies purified from serum from patients with systemic lupus erythematosus (SLE) by cardiolipin micelles were studied for their effects on lymphocytes and neutrophils. At a concentration of 160 micrograms/ml they markedly suppressed the [3H]thymidine incorporation of mononuclear cells stimulated by phytohaemagglutinin (4.9 (SEM 1.9%) of the control) and pokeweed mitogen (26....
