Abstract

<b><i>Introduction:</i></b> Di(2-ethylhexyl) phthalate (DEHP) is a plasticizer commonly used in blood bags. Despite its protective effects on red blood cell (RBC) storage, concerns about its reproductive toxicity exist. This study investigated the in vitro quality of RBC concentrates stored in bags using di(isononyl) cyclohexane-1,2-dicarboxylate (DINCH) as an alternative plasticizer. <b><i>Methods:</i></b> Using a pool-and-split study design, we produced 20 matched homogenous quintets of RBC concentrates in two DINCH bags and three DEHP bags with citrate phosphate dextrose adenine (CPDA-1) anticoagulant. RBC storage quality was assessed weekly for 35 days. <b><i>Results:</i></b> On day 35, the median hemolysis levels in the DINCH bags (0.297–0.342%) were marginally higher (<i>p</i> &lt; 0.05) than the DEHP bags (0.204–0.240%). All DINCH bags showed &lt;0.8% hemolysis. RBCs in the DINCH bags showed increased mean corpuscular volume and decreased eosin 5′ maleimide binding than in the DEHP bags. Higher pO<sub>2</sub> and lower pCO<sub>2</sub> levels in the DINCH bags indicated better gas permeability than in DEHP bags. Other metabolic parameters were comparable in both bags. Compared to DEHP, DINCH exhibited considerably lower levels of plasticizer leaching into blood bags. <b><i>Conclusion:</i></b> The quality of RBC concentrates stored for 35 days in DINCH-plasticized blood bags with CDPA-1 is generally comparable to those in DEHP bags. Hence, DINCH can be a viable alternative to DEHP in blood bags for nonleukoreduced RBC storage even without the use of next-generation additive solutions to improve RBC preservation quality.
