Abstract Background
Biochemical changes induced in red blood cells (RBCs) during storage may impair their function upon transfusion. Transfusion-associated stresses may further amplify storage lesion effects including increased phosphatidylserine (PS)-exposure at the RBC membrane, microparticle (MP)-release and adhesion to endothelial cells (ECs). RBC stress susceptibility in vitro was investigated in relation to storage time and additive solution.

Study design and methods
Leukocyte-reduced whole blood donations (n=18) were paired, mixed and re-split before separating the RBCs for storage in SAGM or AS-1 solutions. Samples were taken after 3, 21 or 35 days. For oxidative stress treatment RBCs were exposed to 0.5mM tert-butylhydroperoxide. Transfusion-associated stress was simulated by overnight culture at 37 °C with plasma containing inflammatory mediators. PS-exposure and MPs were measured by flow cytometry and adhesion to EC was tested under flow conditions. PS specificity of adhesion was tested by blocking with PS-containing lipid vesicles.

Results
Oxidative stress induced significantly higher PS-exposure and adhesion to ECs in RBCs stored for 35 days compared to 3 days (p<0.04). PS-containing vesicles blocked RBC-EC adhesion. After overnight culture with or without plasma, PS-exposure and EC-adhesion were significantly increased (p<0.05). MP numbers increased with longer RBC storage and after RBC culture with plasma. Culture conditions influenced MP numbers from day 35 RBCs. RBCs stored in SAGM had significantly higher PS-exposure after stress treatment than AS-1 RBCs (p<0.02).

Conclusion
Storage for 35 days significantly increased RBC susceptibility to oxidative and in vitro transfusion-associated stresses and was higher for RBCs stored in SAGM compared to AS-1
