Serum muscle enzymes and standard inflammatory markers at time of diagnosis in idiopathic inflammatory myopathies – a retrospective analysis

Objectives: To characterise standard inflammatory markers (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), leucocyte count) and serum muscle enzymes (creatine kinase (CK), myglobine) at the time of diagnosis in patients with idiopathic inflammatory myopathies (polymyositis (PM), dermatomyositis (DM), Jo-1 syndrome (Jo-1), sporadic inclusion body myositis (sIBM)). Methods: We analysed retrospectively levels for CK, myglobine, CRP, ESR, and leucocyte count in patients at time of diagnosis in which muscle biopsy had confirmed the diagnosis of idiopathic inflammatory myopathy. Results: 61 therapy naï…
