Dilated cardiomyopathy complicating a case of epidermolysis bullosa dystrophica.

A child with epidermolysis bullosa dystrophica, recessive type (EBDR) developed significant anemia at 9 years of age and was treated with long-term transfusion therapy. At age 17 he had symptoms of congestive heart failure secondary to dilated cardiomyopathy. Treatment with digoxin and vasodilators for the past year has failed to improve his cardiomyopathy significantly. Chronic iron overload and secondary hemosiderosis may have contributed to his problems, and we propose that chelation therapy be used in any child receiving long-term transfusion therapy.
