| Abstract | Background Packed red blood cell (PRBC) transfusions are routine in neonatal care and the most common blood product administered to sick neonates. However, their impact on leukocyte and platelet profiles in very low birth weight (VLBW) preterm infants remains largely unexplored. This study examines leukocyte profile shifts and platelet dynamics following leukoreduced PRBC transfusions in VLBW preterm infants, offering insights to improve neonatal care and reduce unnecessary interventions. Methods The study utilized a retrospective cohort design within a single center, focusing on VLBW preterm infants who received PRBC transfusions at a level 3 NICU between January 2014 and June 2019. Data collection encompassed white blood cell (WBC) and platelet count measurements taken 24 hours before and up to 72 hours after PRBC transfusion. Neonates lacking complete blood count (CBC) data within the 72-hour post-transfusion window were excluded. A subgroup analysis distinguished the outcome between the initial PRBC transfusion and subsequent ones. The statistical significance of pre- and post-transfusion laboratory data was determined using the Wilcoxon signed ranks test and paired T-test. Results A cohort of 108 VLBW preterm infants who underwent a total of 402 PRBC transfusions was included in the analysis. The subjects exhibited a mean gestational age of 27.2 ± 2.5 weeks and a mean birth weight of 913 ± 264 grams. Analysis of pre- and post-transfusion data revealed no significant differences in total white blood cell count (WBC), absolute neutrophil count (ANC), absolute monocyte count (AMC), absolute eosinophil count, and absolute lymphocyte count. Notably, the platelet count was significantly decreased in the post-transfusion group (p < 0.001). In a subset analysis limited to the first-time transfusions among the 108 infants, a statistically significant increase was observed in total WBC, AMC, and ANC following transfusion. Conclusions The findings of this study highlight that PRBC transfusions can prompt an increase in neutrophils, monocytes, and eosinophils, coupled with a decline in platelet counts, all within a 72-hour window post-transfusion. Notably, these changes were predominantly discernible after the initial transfusion, with subsequent transfusions demonstrating consistency, except for the observed platelet count reduction. Recognizing these patterns could prove instrumental in averting undue investigations for suspected sepsis, particularly following the initial transfusion event. However, further in-depth investigations are necessary to uncover the underlying factors responsible for the shifts in leukocyte and platelet profiles triggered by PRBC transfusions. |
