[Clinical experience in HFR with a new resin-only sorbent cartridge].
Adsorbent therapies have become increasingly popular over the last several years as they permit an additional method to selectively or non-selectively remove toxins. Adsorbents offer a unique removal strategy as they have an extremely high adsorption capacity due to their great surface area. This paper describes experiments that utilized a synthetic divinylbenzene styrenic resin cartridge to remove uremic toxins from chronic renal failure patients. The resin-only cartridge was tested as an alternative after a small number of patients (primarily taking ACE inhibitors) experienced gastrointestinal problems using hemodiafiltration with on-line regeneration (HFR). Subsequent laboratory evidence suggested that the particular carbon used in the cartridge was able to activate contact phase activation. This could potentially cause problems in patients taking ACE inhibitors, as they are unable to degrade bradykinin efficiently. The resin-only cartridge was tested in at 6 centers throughout Italy and included patients that had experienced previous reactions to the carbon-resin cartridge. At the conclusion of the study, no adverse reactions were reported and the cartridge exhibited excellent removal of b2 microglobulin and angiogenin.
