Manufacturer Narrative

Lot number and expiry information are not available at this time.Article citation: zhao j, gabriel e, norda r, et al.Frequent platelet donation is associated with lymphopenia and risk of infections: a nationwide cohort study.Transfusion.(b)(6) 2020; https://doi.Org/10.1111/trf.16175 investigation is in process.A follow-up report will be provided.

Event Description

According to the article, "frequent platelet donation is associated with lymphopenia and risk of infections: a nationwide cohort study", a study found that 30% of frequent plateltpheresis donors had severe t-cell lymphopenia (<200x10^6 cellls/l), which persisted for at least a year after ceasing donations.The findings were rerported using cobe spectra with a leukoreduction system (lrs) chamber.According to the article, "the clinical significance of plateletpheresisassociated lymphopenia is unclear, and there are no studies addressing long-term health effects of repeated lymphocyte depletion in plateletpheresis donors." for common bacterial infections, there was an increased risk for infections only among most frequent donors with more 50 donations (hr, 2.5; 95% ci, 1.2-4.9).Events were rare, with only five events (4.6/1000 person-years) for the most frequent donors with more than 90% lrs donations.For immunosuppression-related infections, no statistical difference could be found; among most frequent donors.Patient details, including patient information and outcomes are not available.The article was based on a past study and did not include patient details, therefore this report is being provided as a summary of the events.The disposable set is not available for return because it was discarded by the customer.

Manufacturer Narrative

This report is being filed to provide investigation: it was unclear if medical intervention was required for the lymphopenia.The article made no allegation of device malfunction.The article provides evidence of an increased risk of infections among frequent plateletpheresis donors using an lrs chamber but does not stratify the rates specifically for cobe spectra.Overall, the study shows that there was an increased risk for infections among frequent donors with greater than 50 donations when comparing donations solely using an lrs chamber donations solely without a lrs chamber."events were rare, with only five events (4.6/1000 person-years) for the most frequent donors with more than 90% lrs donations.For immunosuppression-related infections, no statistical difference could be found; among most frequent donors.¿ dhr details: since this was a retrospective nationwide cohort study to assess the risk of infections associated with plateletpheresis donations using an lrs chamber involving a total of 74,408 apheresis donors in sweden between 1996 and 2017, the lot numbers are unknown; therefore, a dhr search could not be conducted for the reported incident.All lots must meet acceptance criteria for release.Root cause: a definitive root cause could not be determined.Possible causes include but are not limited to: - low t-lymphocyte counts as thymic output declines with age - donors physiology and other risk factors for infections.

Event Description

This was a retrospective nationwide cohort study to assess the risk of infections associated with plateletpheresis donations using an lrs chamber involving a total of 74,408 apheresis donors in sweden between 1996 and 2017 (52% male, 48% female with a mean age of 32.7 years).A request for specific patient information is not feasible.
