Evaluation of Fatty Acids in Membrane Phospholipids of Erythrocytes in Retinitis pigmentosa Patients

Abstract
Several investigators have observed abnormalities of plasma DHA in various common forms of retinitis pigmentosa. Erythrocyte membranes are an accessible tissue which may more closely reflect neural membrane fatty acid levels, but little data is yet available on their fatty acid composition in retinitis pigmentosa patients. We have evaluated the DHA levels in red blood cells membrane phospholipids in various genetic forms of retinitis pigmentosa and relative controls. The results obtained indicate significantly lower DHA levels in red blood cell membrane phospholipids in retinitis pigmentosa patients with respect to controls (p
