aAll patients are chronic hemodialysis patients except Yamamoto et al. (acute HD patients, n = 50; chronic HD patients, n = 104).

bDefined as a greater than 20% reduction in platelet counts.

cDialyzer clotting defined as a consequence of HIT (other forms of thrombosis observed only in one patient). dOf 419 patients, 107 patients had access thrombosis. However, no significant correlation was observed between presence of HIT antibodies and access thrombosis.

Abbreviations: HD, hemodialysis; HIT, heparin-induced thrombocytopenia; NA, not available.

ill patients undergoing continuous venovenous HD (Burgess and Chong, 1997); this heparin-induced platelet proaggregatory effect is less marked with LMWH, and absent or negligible with danaparoid sodium.
