Plasma lipid patterns in chronic renal failure.

E L Lamberth, J A Oates

    Transactions - American Society for Artificial Internal Organs
    |January 11, 1975
    PubMed
    Summary

    Patients with chronic renal failure show reduced polyunsaturated fatty acids in their plasma lipids. This lipid alteration may contribute to accelerated atherosclerosis and uremic platelet dysfunction in these patients.

    Area of Science:

    • Biochemistry
    • Nephrology
    • Cardiovascular Science

    Background:

    • Uremia, a condition of chronic kidney disease, is associated with significant metabolic disturbances.
    • Altered plasma lipid profiles are frequently observed in patients with chronic renal failure.

    Purpose of the Study:

    • To investigate the specific abnormalities in plasma lipid composition in uremic patients.
    • To explore the potential link between these lipid changes and the increased risk of atherosclerosis in chronic renal failure.

    Main Methods:

    • Analysis of plasma lipid fractions.
    • Qualitative assessment of fatty acid composition, focusing on polyunsaturated fatty acids.

    Main Results:

    • A qualitative decrease in polyunsaturated fatty acids was observed across various lipid fractions.
    • A relative deficiency in essential fatty acids, particularly arachidonic acid, was identified.

    Conclusions:

    • Plasma lipid abnormalities, characterized by reduced polyunsaturated fatty acids, are present in uremia.
    • These lipid alterations may play a role in the accelerated atherosclerosis seen in chronic renal failure patients.
    • The deficiency of essential fatty acids might be implicated in the development of uremic platelet disorders.
