Abstract
Plasma Lps of the patients on maintenance hemodialysis and the patients with other specific renal diseases have been studied. The patients on hemodialysis frequently showed gross abnormality in their plasma Lps, which was differentiated from the abnormalities demonstrated in other renal diseases or clinical entities. An exception was type-III hyperlipoproteinemia; i.e. Lp electrophoretograms of the hemodialysis patients resembled those ultracentrifugal fractions had been made had VLDL of beta-migration in paper electrophoresis and another had VLDL or pre-beta-migration. During hemodialysis, intravascular lipolysis, accelerated by heparin infusion, affected all plasma Lps, producing an increase of alpha-Lps and cholestrol ester-rich-beta-Lp. The accelerated triglyceride hydrolysis under circumstances of high glucose availability may stimulate resynthesis of endogenous triglyceriderich Lps, which characterizes the plasma Lp abnormality in more than half of the hemodialysis patients. The abnormality may not be attribuate to the predisposing renal disease but due to an accumlation of the characteristic Lp during the course of maintenace hemodialysis. A possible cause of accelerated atherosclerosis in the hemodialysis patients may be the accumulation of remnants of plasma Lp catabolism and the stimulated synthesis of triglycerdie-rich plasma Lp.
