Zusammenfassung
Objectives: Mitochondrial changes were frequently reported in inclusion body myositis (IBM) and occasionally in dermatomyositis (DM) as well as in polymyositis (PM). The aim of this study was to analyse frequencies of myohistological mitochondrial changes and of a 4977 base pair deletion – so called common deletion (CD)-of mitochondrial DNA (mtDNA) in clinically well-described patients with IBM, DM and PM. Methods: Two examinations were carried out in 35 patients (10 IBM, 12 PM, 13 DM): (1) a quantitative analysis of myohistological mitochondrial changes using the cytochrome c oxidase/succinate dehydrogenase (CO…
