Abstract:
:Platelet concentrates (PCs), stored for 5 days in PL 2209, a new polyvinyl chloride (PVC) storage container plasticised with butyryl trihexyl citrate, were compared with those stored in PL 1240, a PVC platelet container plasticised with triethylhexyl trimellitate. In part 1 of the study, pooled platelet-rich plasma (PRP) was aliquoted into each type of pack and pH, pCO2, pO2, hypotonic shock response, aggregation responses, lactate, glucose and ATP concentrations, and lactate dehydrogenase and beta-thromboglobulin release were compared at days 1, 3 and 5. In part 2, 12 volunteers gave a unit of blood on two separate occasions and PCs produced by the PRP method were stored in PL 2209 or PL 1240 for 5 days before autologous reinfusion of a 111In-labelled sample. In vitro results demonstrated that PL 2209 was more gas permeable than PL 1240. In part 2 of the study, at day 5, pCO2 was 3.13 +/- 0.62 versus 5.14 +/- 0.69 (p < 0.001), whilst pO2 was not significantly different for PL 2209 versus PL 1240, respectively. pH was better maintained in PL 2209 than in PL 1240 (7.38 +/- 0.13 vs. 7.24 +/- 0.10, respectively, p < 0.01) after storage for 5 days. These results were confirmed by those from part 1. In vivo data were similar for PC stored in the two plastics with a multiple-hit recovery of 40.9 +/- 12.1% for PL 2209 and 37.4 +/- 11.3% for PL 1240, and a multiple-hit survival of 4.89 +/- 1.20 days and 5.28 +/- 2.06 days for PL 2209 and PL 1240, respectively. gamma-Camera imaging of volunteers showed similar biodistribution of radiolabelled platelets stored in each container. These results demonstrate that PL 2209 is a suitable container for storage of PCs for 5 days.
