Inflammatory muscle diseases.
Inflammatory myopathies are the largest group of potentially treatable myopathies in children and adults. They constitute a heterogeneous group of disorders that are best classified, on the basis of distinct clinicopathologic features, in four subtypes: dermatomyositis, polymyositis, necrotizing autoimmune myositis, and inclusion-body myositis (throughout this review, I use this term to refer s...
متن کاملInflammatory muscle diseases.
The three major immune-mediated inflammatory myopathies, dermatomyositis (DM), polymyositis (PM) and inclusion body myositis (IBM), each have their own distinctive clinical features, underlying pathogenetic mechanisms and patterns of muscle gene expression. In DM a complement-dependent humoral process thought to be initiated by antibodies to endothelial cells results in a microangiopathy with s...
متن کاملMolecular immunology and genetics of inflammatory muscle diseases.
Polymyositis, dermatomyositis, and inclusion body myositis, although immunopathologically distinct, share 3 dominant histological features: inflammation, fibrosis, and loss of muscle fibers. Progress in molecular immunology and immunogenetics has enhanced our understanding of these cellular processes. Based on the T-cell receptor gene rearrangement, the autoinvasive CD8+ T cells in polymyositis...
متن کاملInflammatory muscle diseases: a critical review on pathogenesis and therapies.
Based on unique clinicopathological criteria, the most common immune inflammatory muscle disorders include Dermatomyositis (DM), Polymyositis (PM), Necrotizing Myositis (NM), and sporadic Inclusion Body Myositis (sIBM). DM is an undeniably a complement-mediated microangiopathy with destruction of capillaries, hypoperfusion, and inflammatory cell stress on the perifascicular regions. Necrotizing...
متن کاملDiagnostic Utility of Auto-Antibodies in Inflammatory Muscle Diseases.
To date, there are four main groups of idiopathic inflammatory myopathies (IIM): polymyositis (PM), dermatomyositis (DM), immune-mediated necrotizing myopathy (IMNM) and sporadic inclusion body myositis; based on clinical presentation and muscle pathology. Nevertheless, important phenotypical differences (either muscular and/or extra-muscular manifestations) within a group persist. In recent ye...
