Abstract

Low molecular weight (LMW) heparin has been compared to standard unfractionated (UF) heparin in hemodialysis/hemofiltration in a 12 month, randomized study. Seventy patients with end-stage chronic renal failure starting dialysis treatment were randomly assigned to one of two groups treated with either LMW or UF heparin. The LMW and UF heparin doses used produced similar plasma anti-FXa levels, and comparable antithrombotic effectiveness was observed in the two groups as reflected in similar incidences of thrombus formation in the extracorporeal circulation: 1.59% and 1.33% for LMW and UF heparin, respectively. No bleeding complications were seen with either heparin, but significantly (P less than 0.05) fewer erythrocyte concentrates were needed in the LMW heparin patients. Mean factor VIII activities had risen significantly (P less than 0.001) after 12 months in the UF heparin group, whereas they were unchanged in the LMW heparin group. A significant (P less than 0.05) increase in plasma triglycerides was observed in the UF heparin group which was attributable to six (18.8%) of the patients in this group. Triglyceride concentrations remained relatively constant in the LMW heparin group. Post-heparin lipolytic activity, and in particular hepatic lipase activity, was not stimulated to the same extent in the LMW heparin-treated patients as compared to the UF heparin group. We conclude that LMW heparin is a suitable alternative to standard UF heparin for anticoagulation in hemodialysis/hemofiltration therapy. It may offer potential advantages with regard to a lower requirement for erythrocyte concentrates and less derangement of certain metabolic parameters, such as factor VIII, triglycerides and plasma lipase activity.
