Background
Adsorption cartridges applied in extracorporeal purification therapies, involve direct contact of blood with the sorbent material. The potential induced cytotoxicity is an important issue. The aim of this study was to investigate potential in vitro cytotoxic effects of sorbent cartridges HA130, HA230, HA330/380 (Jafron, China) on U937 monocytes.
Methods
Monocytes were exposed to the sorbent material in static and dynamic manners. In static test, cell medium samples were collected after 24 hrs of incubation in the cartridges. In dynamic test, hemoperfusion modality has been carried out and samples at 30, 60, 90 and 120 min were collected.
Results
Compared to control samples, the viability remained the same and there was no evidence of increased necrosis or apoptosis in monocytes exposed to the cartridges in the static tests (fig.1). Similarly, there was no remarkable difference in the viability, apoptosis and necrosis of U937 between each sample and the controls during the dynamic test (fig.2).
Conclusion
Our in vitro testing suggests that HA130, HA230, HA330/380 cartridges possess an optimal level of biocompatibility and their use in HP is not associated with adverse reactions or signs of cytotoxicity.
