Coagulation and fibrinolytic activities in 2 siblings with β2-glycoprotein I deficiency

Optimization of Unnicked β2-Glycoprotein I and High Avidity Anti-β2-Glycoprotein I Antibodies Isolation

Patient biological material for isolation of β2-glycoprotein I (β2GPI) and high avidity IgG anti-β2-glycoprotein I antibodies (HAv anti-β2GPI) dictates its full utilization. The aim of our study was to evaluate/improve procedures for isolation of unnicked β2GPI and HAv aβ2GPI to gain unmodified proteins in higher yields/purity. Isolation of β2GPI from plasma was a stepwise procedure combining n...

Structural Changes in β2-Glycoprotein I and the Antiphospholipid Syndrome

Regional left atrial coagulation and fibrinolytic activities in patients with mitral stenosis.

Systemic thromboembolism is a major complication of mitral stenosis (MS), especially in those patients having atrial fibrillation (AF). Recent evidence has suggested that regional left atrial coagulation activity may be increased in MS and may contribute to the pathophysiology of left atrial thrombus. However, the relation of left atrial coagulation activity to factors that predispose to left a...

Cardiolipin and β2-Glycoprotein I antibodies associate with cognitive impairment and seizure frequency in developmental disorders

Cardiolipin (CL) and β(2)-Glycoprotein I (β(2)-GpI) antibodies have been shown to associate with various neurological symptoms including seizures and cognitive dysfunction. Here we studied the prevalence of CL, β(2)-GpI and antinuclear (ANA) antibodies in 74 patients with various developmental disorders with epilepsy and 70 healthy controls. Developmental disorders were classified into genetic ...

Coagulation and fibrinolytic profiles in patients with severe pulmonary hypertension.

STUDY OBJECTIVES Although in situ thrombosis is a prominent finding in lung vessels from patients with primary and secondary pulmonary hypertension, to our knowledge, plasma coagulation factors that might contribute to a hypercoagulable state have not been fully investigated. We hypothesized that the local coagulation environment in the lung vasculature is important to progression if not initia...
