Myopathy with mitochondrial inclusion bodies: histological and metabolic studies.
Apparently new information about a metabolic abnormality has been obtained by measuring biochemical and respiratory responses to controlled exercise in a patient with abnormal mitochondria in muscle fibres. A male patient (49 years old) presented with bilateral ptosis of 15 to 20 years' duration and weakness for one to two years. Biopsies from the deltoid and triceps muscles were subjected to h...
متن کاملAdult-onset mitochondrial myopathy.
Mitochondrial diseases are polymorphic entities which may affect many organs and systems. Skeletal muscle involvement is frequent in the context of systemic mitochondrial disease, but adult-onset pure mitochondrial myopathy appears to be rare. We report 3 patients with progressive skeletal mitochondrial myopathy starting in adult age. In all cases, the proximal myopathy was the only clinical fe...
متن کاملClevudine Induced Mitochondrial Myopathy
Clevudine was approved as an antiviral agent for hepatitis B virus, which showed marked, rapid inhibition of virus replication without significant toxicity. However, several studies have reported myopathy associated with clevudine therapy. Also, we experienced seven patients who suffered from myopathy during clevudine therapy. To characterize clevudine-induced myopathy, we collected previously ...
متن کاملScoliosis in Mitochondrial Myopathy
The mitochondrial myopathies include a diverse group of disorders characterized by morphological abnormalities of muscle mitochondria. Little is reported about spinal deformity associated with this syndrome. This study presents a case of scoliosis occurring in the setting of mitochondrial myopathies and explores the possible mechanisms between the 2 diseases. A previously unreported scoliosis i...
متن کاملNuclear genetic control of mitochondrial translation in skeletal muscle revealed in patients with mitochondrial myopathy.
Oxidative phosphorylation deficiencies can be caused by mutations in either the nuclear genome or the mitochondrial genome (mtDNA); however, most pathogenic mutations reported in adults occur in mtDNA. Such mutations often impair mitochondrial translation, and are associated with a characteristic muscle pathology consisting of a mosaic pattern of normal fibres interspersed with fibres that show...
