Abstract
BACKGROUND AND OBJECTIVES
Blood donor variability can affect the storage properties of packed red blood cells (PRBCs). This study aimed to determine the association of donor characteristics with in vitro storage haemolysis of PRBCs.
MATERIALS AND METHODS
In the prospective observational study, a total of 109 whole blood donors were enrolled using the purposive sampling method. A pre-donation sample was collected for haemoglobin (Hb) and serum uric acid (UA) levels. PRBC aliquots were tested for potassium, lactate dehydrogenase (LDH), Hb, haematocrit, plasma Hb and haemolysis on days 1, 21 and 35 of storage. The association of these parameters with donor age, sex, donation status, dietary pattern and body mass index was determined.
RESULTS
Mean haemolysis was significantly higher in PRBCs from donors with UA levels ≤6 mg/dL than donors with UA levels >6 mg/dL on day 35 of storage (0.22 ± 0.11 vs. 0.18 ± 0.07, p = 0.03). Median plasma Hb (mg/L) was significantly higher in PRBCs from first-time donors on day 21 (586 vs. 509, p = 0.05) and day 35 (1507 vs. 1358, p = 0.02) of storage in comparison to frequent donors. Significantly higher mean potassium (p = 0.04 day 1; p = 0.02 day 21) and median LDH values (p = 0.02 day 1, p = 0.05 day 21) were observed in PRBCs from male donors. A statistically significant positive association was observed between donor UA and LDH levels of PRBCs on day 35 of storage (β coefficient: 715.52, p-value: 0.003) on multiple regression analysis.
CONCLUSION
In vitro haemolysis of PRBCs is affected by blood donor characteristics.
