Reduced lipid concentrations during four years of dialysis with low molecular weight heparin.
Heparin is used as standard anticoagulant in the extracorporeal circuit of hemodialysis. Widespread use of this drug revealed several potentially adverse effects, such as release of lipoprotein lipase and hepatic lipase from the endothelial surface. Recently it was found that anticoagulatory potency and provocation of adverse effects are linked to different subfractions of heparin. A heparin subfraction of 4000 to 6000 Daltons rather specifically inhibits factor Xa and therefore has a very high antithrombotic potency. Its effects on release of lipases are minor. During a four year period five patients on maintenance hemodialysis were treated with this low molecular weight heparin (LMWH) subfraction. Additionally, another five patients successively received standard heparin, LMWH and again standard heparin. At all circumstances during treatment with LMWH there was a significant (0.001 less than P less than 0.05) reduction both of cholesterol and triglyceride blood concentrations. LMWH is efficient in avoiding clotting in extracorporeal circuit during hemodialysis in doses of 17 to 95 U/kg (initial dose) and 7 to 20 U/kg/hr (continuous dose).
