    Abstract:
    BACKGROUND: Biochemical abnormalities, increased efflux of soluble enzymes and muscle proteins, and altered permeability of muscle membranes imply the presence of a disorganized erythrocyte membrane in Duchenne muscular dystrophy (DMD). The purpose of the present study was to investigate this hypothesis of a generalized membrane defect. MATERIALS AND METHODS: Twenty-five patients with the disease were analyzed for their erythrocyte lipid composition and for alterations in their fatty acid content compared to twenty-five healthy subjects. RESULTS: DMD patients showed a decreased concentration of total phospholipids compared to healthy volunteers, with striking fluctuations in concentrations of erythrocyte long chain fatty acids. Specifically, the unsaturated fatty acids such as oleic, linoleic and arachidonic acids were significantly decreased in the disease, whereas the saturated fatty acid, palmitic acid was increased in DMD patients compared to healthy controls. CONCLUSION: Our findings suggest an abnormal fatty acid composition and disorganization of erythrocyte membrane in patients with DMD associated with possible functional alterations.
