Early cardiac screening necessary for muscular dystrophy patients

31.10.2005


Early diagnosis and treatment of heart disease may lead to longer life in Duchenne and Becker muscular dystrophy patients, say experts at Baylor College of Medicine (BCM) and Texas Children’s Hospital in Houston in a report that appeared online in the journal Circulation.



Cardiac disease, particularly dilated cardiomyopathy and heart failure, is the major cause of mortality in patients with muscular dystrophy and is present in most boys with Duchenne muscular dystrophy and approximately 70 percent of those with Becker muscular dystrophy. These are the two common forms of muscular dystrophy caused by defects in a gene called dystrophin.

"It should be the standard of care for all newly diagnosed Duchenne and Becker muscular dystrophy patients to be referred to a cardiologist for screening, probably by 10 years of age or earlier," says Dr. Jeffrey A. Towbin, professor of pediatrics at BCM and chief of pediatric cardiology at Texas Children’s Hospital.


Towbin and his group studied 69 boys with DMD and BMD. After the first abnormal echocardiogram, which occurred at 14-15 years, 31 boys were started on ACE inhibitor or beta blocker therapy. During the follow-up two patients remained stable with their dilated cardiomyopathy, eight showed improvement and 19 normalized both heart size and function.

"This study also helped us realize that while some dystrophin-gene mutations are predictors of early onset cardiac abnormalities, others may actually protect against early development of these abnormalities," says Towbin.

Cardiac symptoms typically appear late in the course of cardiomyopathy, in part because affected individuals are usually wheelchairchair bound and often physically inactive. Heart disease progresses quickly, leading to premature death, often before 25 years of age.

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
