Rheumatoid Arthritis Followed by Systemic Lupus Erythematosus

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 ...

Frequency of neoplasia in systemic lupus erythematosus and rheumatoid arthritis.

A patient population admitted to the hospital for either SLE or RA was surveyed for the subsequent development of neoplasms. The frequency of neoplasm in SLE patients appeared to be exaggerated, whereas the frequency of subsequent neoplasm in rheumatoid patients was unexpectedly low. A paucity of nephritis in the SLE group was noted. Further reports are encouraged so that the magnitude of the r...

Rheumatoid arthritis and systemic lupus erythematosus as immune complex diseases.

Rheumatoid factors are 9s IgM autoantibodies directed against the hinge regions of 7s IgG's that have been changed consequent to their encounter with a foreign antigen, such as those produced by oral bacteria. Occasionally self-aggregating 7s IgG's serve this function. When these complexes are taken up by phagocytes in the joint, they form the "RA cell," a cell analogous to the LE cell of Hargr...
