Favourable clinical course in an infant with severe deficiency of complex III of the respiratory chain combined with less severe deficiencies of complexes I, II and IV
An infant with severe deficiency of complex III combined with less severe deficiencies of complexes I, II and IV of the mitochondrial respiratory chain in skeletal muscle tissue presented with intra-uterine g...

Neonatal De Toni-Debré-Fanconi syndrome due to a defect in complex III of the respiratory chain
A patient with neonatal expression of severe De Toni-Debré-Fanconi syndrome is presented. Because of early signs of renal tubulopathy together with a large urinary excretion of lactate, 3-hydroxybutyrate and c...

A retrospective study of patients with the hereditary syndrome of congenital cataract, mitochondrial myopathy of heart and skeletal muscle and lactic acidosis
The objectives of this study were to describe the course of two forms of an hereditary syndrome characterised by congenital cataract, mitochondrial myopathy of heart and skeletal muscle and lactic acidosis. We...

Problems with the biochemical diagnosis in mitochondrial (encephalo-)myopathies
Patients suffering from a mitochondrial (encephalo-)myopathy have a remarkable clinical heterogeneity. A reliable and extensive investigation must be performed in order to obtain a correct diagnosis, but many ...

Combined deficiencies of the pyruvate dehydrogenase complex and enzymes of the respiratory chain in mitochondrial myopathies
In six patients with mitochondrial (encephalo-) myopathy investigations of skeletal muscle revealed a defect of pyruvate dehydrogenase complex (PDHC) in combination with one or more respiratory chain complex d...

Prenatal diagnosis of systemic disorders of the respiratory chain in cultured amniocytes and chorionic villus fibroblasts by studying the formation of lactate and pyruvate from glucose
Formation of lactate and pyruvate from glucose was studied in cultured amniocytes and chorionic villus fibroblasts from controls, either untreated or treated with azide, an inhibitor of cytochromec oxidase, or ot...

Increased volume density of peripheral mitochondria in skeletal muscle of children with exercise intolerance
Muscle biopsies from 17 children with exercise intolerance and other miscellaneous symptoms and signs showed changes in mitochondrial content. The patients could not be classified according to known criteria. ...

Isolated and combined deficiencies of NADH dehydrogenase (complex I) in muscle tissue of children with mitochondrial myopathies
We describe eight children with complex I deficiency, four of them with an isolated, the other four with an additional deficiency of complex IV. Clinical, chemical and morphological findings were compared from...

Deficiency of the α and β subunits of pyruvate dehydrogenase in a patient with lactic acidosis and unexpected sudden death
An infant with moderate muscular hypotonia and congenital lactic acidosis died suddenly at the age of 3 months. Autopsy revealed no abnormalities responsible for this unexpected death. Measurement of mitochond...

Article
Fatal neonatal cardiomyopathy associated with cataract and mitochondrial myopathy
Three patients suffering from the neonatal form of a syndrome characterized by congenital cataract, hypertrophic cardiomyopathy, and mitochondrial myopathy are described. The patients died at 7, 10 and 18 days...

Mitochondrial Myopathies: Multiple Enzyme Defects in the Respiratory Chain
Approximately 100 patients suffering from disturbed energy metabolism of the skeletal muscle mitochondria have been reported in the literature. A malfunction of the respiratory chain was found in about two-thi...

Article
Disorders of the mitochondrial respiratory chain: clinical manifestations and diagnostic approach
The clinical identification of patients with defects in the mitochondrial respiratory chain is almost impossible. We describe screening tests that should be performed in order to select those patients in whom ...

Mitochondrial myopathy with lactic acidaemia, Fanconi-De Toni-Debré syndrome and a disturbed succinate: cytochrome c oxidoreductase activity
A patient with severe muscular hypotonia, failure to thrive, a metabolic acidosis and a renal tubular dysfunction is presented. The disease followed a fatal course. Blood lactate and pyruvate levels as well as...
