Autoantibody to CD40 ligand in systemic lupus erythematosus: association with thrombocytopenia but not thromboembolism.

Anticardiolipin Antibodies in Juvenile Rheumatoid Arthritis and Systemic Lupus Erythematosus

Background: Antiphospholipid antibody syndrome (APS) can either occur as a primary syndrome or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Anticardiolipin antibody (aCL) of IgG and/or IgM isotype in blood, measured by a standardized ELISA is the most acceptable laboratory criteria. APS IgG isotype, particularly IgG2 subclass is more strongly associated ...

Large Ovarian Hemorrhagic Cyst and Immune Thrombocytopenia as Early Manifestations of Systemic Lupus Erythematosus (SLE)

Hematologic abnormali"es are generally present among systemic lupus erythematosus pa"ents. Idiopathic thrombocytopenic purpura can be the first manifesta"on of SLE, followed by other symptoms and signs of disease appearing several years later. Although bleeding due to immune thrombocytopenic purpura is usually mild and occurs in mucocutaneous surfaces, but it may be severe and represent in u...

Isolated thrombocytopenia report of a rare presentation of childhood Systemic Lupus Erythematosus

 Background: Systemic lupus erythematosus (SLE) has various presentations in children. Hematologic abnormalities is common in childhood onset of SLE, however, isolated thrombocytopenia is relatively rare. Thus, we present a child with isolated thrombocytopenia as a rare presentation of SLE. Case presentation: A 12-year-old boy with chief complaints of loss of appetite, weight loss, decrease...

Anti-S Alloantibody Underlying Pan Agglutinating Autoantibody in a Patient of Systemic Lupus Erythematosus

The soluble CD40 ligand sCD154 in systemic lupus erythematosus.

We found that the plasma of patients with active systemic lupus erythematosus (SLE) could induce a human B-cell line (Ramos) to express high levels of immune accessory molecules that are commonly found on blood B cells of patients with active SLE. The ability of SLE plasma to induce such phenotypic changes could be abrogated by neutralizing antibodies specific for the CD40 ligand (CD154) but no...
