Objective: To investigate treatment effects of high-dose prednisone (PRED) and intravenous immune globulin (IVIG) on inflammatory and beta-amyloid-associated proteins in muscles of sIBM patients. Background: Cytokines, chemokines and costimulatory molecules promote inflammation in sIBM. The disease pathogenesis also involves a cascade of degeneration-associated molecules such as amyloid precursor protein (APP) and ubiquitin (UBB). For reasons unknown, IVIG and PRED are ineffective in sIBM, although proven beneficial in other inflammatory muscle disorders. Methods: mRNA was extracted from muscle biopsies of sIBM…
