Erythrocyte survival in Duchenne muscular dystrophy.

Hemolysis was investigated in seven patients with Duchenne dystrophy. No increase in red-cell turnover was detected by indirect measurement (hemoglobin, reticulocyte count, plasma hemoglobin, serum haptoglobin) or by turnover of 51Cr-labeled erythrocytes. Our findings fail to support the likelihood of a significant erythrocyte membrane defect.
