COMPARATIVE ANALYSIS OF RBC MEMBRANE FATTY ACIDS, PROTEINS AND GLYCOPHORIN IN PATIENTS WITH HETEROZYGOUS BETA THALASSEMIA AND IRON DEFICIENCY ANEMIA
Journal Title: Indian Journal of Clinical Biochemistry - Year 2006, Vol 21, Issue 2
Abstract
Membrane lipid and protein composition was compared in erythrocytes from iron deficiency anemia (IDA) and heterozygous beta thalassemia patients. The study was planned to correlate the influence of iron deficiency with the intrinsic defect of the heterozygous condition on the membrane structural integrity as well as to investigate whether there are differences in membrane changes between the two conditions. Results indicate high levels of saturated fatty acids and low unsaturated fatty acids in both disorders although arachidonic acid and the unsaturation index were lower in heterozygous thalassemia than IDA. Nevertheless, neither of the conditions provoked any alterations in membrane protein or glycophorin suggesting alterations in the lipid moiety only. Present findings indicate that irrespective to the etiology, both, iron deficiency and the heterozygous condition show a common pattern of lipid derangement, which may in turn result in increased membrane rigidity and decreased cellular deformability.
