Plasma lipemia: When the blood donor becomes a patient.

Lipemic plasma donations are not a strange phenomenon to blood bankers. According to quality standards for plasma fractionation, lipemic plasma donations must be discarded. Beyond quality control and inventory aspects, plasma lipemia is also an important risk factor for cardiovascular diseases, acute pancreatitis and is associated with overall mortality, however little attention is given to the management of these donors in the literature. A retrospective analysis of every whole blood donation that yielded lipemic plasma between January 1st 2018 and December 31st 2019 was made. The medical examination and donor history for the respective donation was reviewed and the available data was collected regarding hour of donation, gender, age, drugs and coexisting pathologies. Whether the donor was called back for a follow up evaluation regarding the lipemic plasma was also noted. Our blood center received 18274 whole blood donations of which 115 (0,63 %) were reported as having plasma lipemia, in the period of this study. Of these 115 donors, 103 (89,57 %) were male. The average age was 47,63 ± 10,65 years. A clear peak in lipemic plasma donations 4 hours after the classic lunch hours is visible. For 88,70 % of the donors, this was the first time their hypertriglyceridemia was identified. The nonfasting elevation of plasma triglycerides in these donors represents a true metabolic derangement. This is a golden opportunity for early intervention and follow up evaluation is indicated. More attention must be given during the medical evaluation to properly identify donors at risk of lipemic donations.
