produce plasma cells that produce antibodies such as RF, then effector cells are
activated causing macrophages and fibroblasts - ✔✔Pathogenesis of RA

days then rapidly remits

-systemic lupus erythematous - ✔✔++ RF can also be seen in other rheumatic diseases
✔✔-Hep B & C
-sarcoidosis
-malignancy
-primary biliary cirrhosis - ✔✔++RF in non-rheumatic disorders
✔✔Anti-cyclic Citrullinated Peptide Antibodies (Anti-CCP) -higher levels linked to
greater severity of disease - ✔✔produced early in the disease process and can be
useful when RF negative

-Disease modifying anti-rheumatic drugs (DMARDS) -methotrexate -gold std for moder
to severe
-Biologics (genetically engineered immunosuppressives)
-Corticosteroids
-Glucocorticoids (prolonged use =negative effects) - ✔✔Treatment of RA
✔✔Renal disease is relatively uncommon in RA - ✔✔Renal disease is relatively
uncommon in RA
, ✔✔-oligoarticular
