Summary
Extending platelet concentrate shelf-life to five days is possible using new PL732 and CLX plastic bags. These storage solutions maintain platelet viability and function, helping to prevent shortages.
Area of Science:
- Transfusion Medicine
- Biomaterials Science
Background:
- Standard platelet concentrate storage in PL146 bags is limited to 72 hours.
- This short shelf-life contributes to platelet shortages due to decreased viability and survival post-transfusion.
Purpose of the Study:
- To evaluate the efficacy of two new plastic bag types (PL732 and CLX) for extending platelet concentrate storage.
- To assess in vitro and in vivo function of platelets stored for 5 days in these new bags compared to standard 3-day storage.
Main Methods:
- Platelet concentrates were stored for 3 and 5 days in PL732 and CLX bags.
- In vitro tests included pH, platelet count, size, aggregation response, PCO2, lactate, and glucose utilization.
- In vivo assessment involved autologous survival studies and post-transfusion increments in thrombocytopenic patients.
Main Results:
- Platelet concentrates in PL732 and CLX bags maintained pH > 7.0 with minimal changes in count or size after 5 days.
- Aggregation responses were well-preserved, and gas exchange was efficient.
- Five-day storage yielded autologous survivals comparable or superior to 3-day storage in PL146 bags.
- Post-transfusion increments were acceptable in patients.
Conclusions:
- PL732 and CLX plastic bags provide a superior storage environment for platelet concentrates.
- These new bags enable a 5-day shelf-life, improving platelet product quality and supply.
- This advancement can help alleviate challenges in meeting the demand for platelet transfusions.
