Annexin A5 (A5) forms 2-dimensional crystals over phospholipid bilayers, blocking their availability for coagulation reactions. Recently, human antiphospholipid (aPL) monoclonal antibodies (mAbs) have been demonstrated by atomic force microscopy (AFM) to disrupt this crystallization and accelerate coagulation. We therefore performed a study with small, well-defined groups of patients to investi...

Antiphospholipid antibodies (aPLs) have been implicated in atherogenesis. We studied 344 patients with acute coronary syndromes; approximately 40% were aPL+ in 1 or more tests and 60% aPL-. In 215 patients, coronary artery disease (CAD) was angiographically documented, with 43.7% positive for aPL vs 34.9% of patients without CAD positive for aPLs. Anti-beta(2)-glycoprotein I (beta2GPI; 54%) and...

The antiphospholipid syndrome (APS) is characterized by venous and/or arterial thrombosis and severe pregnancy morbidity in presence of antiphospholipid antibodies (aPL). While there is compelling evidence that aPL cause the clinical manifestations of APS, the underlying mechanisms are still a matter of scientific debate. This is mainly related to the broad heterogeneity of aPL. There are three...

Acute promyelocytic leukemia (APL), a relatively rare hematologic malignancy, is highly curable with current treatment strategies. However, these strategies may be unavailable in countries with limited resources. A review of records in several Latin American countries revealed that approximately 30% of deaths among children and adults with APL were caused by early complications associated with ...

Background and Purpose—We sought to estimate risk of recurrent stroke/TIA/death in the subgroup of the Patent Foramen Ovale in the Cryptogenic Stroke Study (PICSS) cohort with patent foramen ovale (PFO) and antiphospholipid antibodies (aPL) and to estimate risk of recurrent stroke/TIA/death in aPL-positive patients who have thickened left-side heart valves (VaT). PFO is associated with cryptoge...

The human immune response is highly complex, dictated by incompletely understood genetic and environmental factors, and it appears to be important in contributing to several forms of cerebrovascular disease. Antiphospholipid-protein antibodies (aPL) have been implicated in immune-mediated clotting in both arterial and venous beds1 and are considered to be the most common hematological condition...

Acute promyelocytic leukemia (APL) is a common subtype of acute myeloid leukemia in China. Since the application of arsenic trioxide and all-trans retinoic acid in the treatment of APL, the prognosis has greatly improved. However, ~20% of patients with APL relapse upon completing chemotherapy. Decreasing the relapse rate and incidence of early mortality may pose the greatest challenges for the ...

Disseminated intravascular coagulation (DIC) frequently occurs in patients with acute promyelocytic leukemia (APL). With the induction of therapy in APL using all-trans retinoic acid (ATRA), DIC can be controlled in most cases as ATRA usually shows immediate improvement of the APL. However, arsenic trioxide (ATO) which has been used for the treatment of relapse in APL patients has shown to take...
