To assess the incidence, nature and evolution of cardiac disease in Duchenne muscular dystrophy, 328 patients were studied between 1976 and 1987 for periods varying from 3 to 11 years. Patients underwent regular clinical examination, electrocardiography, echocardiography and radiological assessment. Pre-clinical cardiac involvement was found in 25% of(More)
OBJECTIVE The aim of the study was to assess different outcome measures in a cohort of ambulant boys with Duchenne muscular dystrophy (DMD) over 12 months in order to establish the spectrum of possible changes in relation to age and steroid treatment. METHODS The study is a longitudinal multicentric cohort study. A total of 106 ambulant patients with DMD(More)
The BIO14.6 hamster is a widely used model for autosomal recessive cardiomyopathy. These animals die prematurely from progressive myocardial necrosis and heart failure. The primary genetic defect leading to the cardiomyopathy is still unknown. Recently, a genetic linkage map localized the cardiomyopathy locus on hamster chromosome 9qa2.1-b1, excluding(More)
Limb-girdle muscular dystrophies (LGMD) are a heterogeneous group of inherited neuromuscular disorders characterized by proximal muscular weakness of the pelvic and shoulder girdles and a variable progression with symptoms, ranging from very severe to mild. One autosomal dominant (LGMD1A, at chromosome 5q22.3-31.3) (ref. 3) and five autosomal recessive (AR)(More)
OBJECTIVE To characterize the presence and behavior of the dystrophinopathic myocardial damage in female carriers of a gene defect at the Xp21 locus of the X chromosome that causes Duchenne and Becker muscular dystrophies (DMD and BMD). DESIGN Cohort study from April 1, 1985, to April 30, 1995, with cardiologic follow-up performed yearly for a minimum of(More)
OBJECTIVES The aim of the study was i) to assess the spectrum of changes over 24 months in ambulant boys affected by Duchenne muscular dystrophy, ii) to establish the difference between the first and the second year results and iii) to identify possible early markers of loss of ambulation. METHODS One hundred and thirteen patients (age range 4.1-17, mean(More)
Mutations in any of the genes encoding the alpha, beta or gamma-sarcoglycan components of dystrophin-associated glycoproteins result in both sporadic and familial cases of either limb-girdle muscular dystrophy or severe childhood autosomal recessive muscular dystrophy. The collective name 'sarcoglycanopathies' has been proposed for these forms. We report(More)
The aim of this study was to investigate the suitability of the North Star Ambulatory Assessment as a possible outcome measure in multicentric clinical trials. More specifically we wished to investigate the level of training needed for achieving a good interobserver reliability in a multicentric setting. The scale was specifically designed for ambulant(More)
Aim of the study was to investigate whether the administration of gentamicin could restore dystrophin expression in striated muscles of patients with Duchenne muscular dystrophy caused by premature stop codon, as reported in mdx mice. Four Duchenne patients, still ambulant or in wheelchair stage for less than 4 months, selected among those with point(More)
Limb girdle muscular dystrophy (LGMD) type 2A (LGMD2A) is caused by mutations in the CAPN3 gene encoding for calpain-3, a muscle specific protease. While a large number of CAPN3 gene mutations have already been described in calpainopathy patients, the diagnosis has recently shifted from molecular genetics towards biochemical assay of defective protein.(More)
