  Sporadic inclusion body myositis: the genetic contributions to the pathogenesis Qiang Gang1,2*, Conceição Bettencourt1, Pedro Machado2, Michael G Hanna1,2 and Henry Houlden1,2 Abstract Sporadic inclusion body myositis (sIBM) is the commonest idiopathic inflammatory muscle disease in people over 50 years old. It is characterized by slowly ...

  An anti-Ku antibody test was positive. A muscle biopsy revealed inflammatory myopathy with rimmed vacu-oles (RVs). The diagnosis of scleroderma-polymyositis (SSc-PM) overlap syndrome was made. RVs on a muscle biopsy in a patient with inflammatory myositis involving axial muscles may be seen either in inclu-sion body myositis or SSc-PM overlap ...

  Polymyositis, Inclusion Body Myositis, IVIg. I. INTRODUCTION NFLAMMATORY myopathies are a heterogeneous group of diseases characterized by muscle weakness and inflammation. They could be classified into 3 main subtypes: polymyositis (PM), dermatomyositis (DM) and inclusion body myositis (IBM). Every subtype has different pathogenesis,

  Sporadic inclusion body myositis sIBM is a rare form of IIM. It is a degenerative autoimmune disease of muscle, with inflammatory infiltrates and inclusion vacuoles. Its prevalence is 1 to 71 per million individuals, rising to 139 per million in people over 50 and varying between different populations. Clinical manifestations of sIBM are muscle weakness and atrophy, preferentially affecting the quadriceps …
