To Estimate the Coagulopathy Potential of Packed RBC Transfusions in Multi-Transfused Patients: A Prospective Cohort...

Area of Science:

• Hematology
• Transfusion Medicine
• Coagulation Science

Background:

• Multi-transfused patients often experience increasing transfusion requirements.
• Packed red blood cell (PRBC) transfusions may influence coagulation.
• Understanding PRBC's procoagulant potential is crucial for managing transfusion therapy.

Purpose of the Study:

• To evaluate the procoagulant potential of PRBC transfusions in multi-transfused patients.
• To assess changes in specific biochemical markers following PRBC transfusion.
• To investigate the relationship between transfusion and coagulopathy.

Main Methods:

• Prospective cohort study involving 31 multi-transfused patients (≥4 lifetime PRBC units).
• Biochemical parameters (HsCRP, LDH, tPA, ATIII, MPs) measured pre- and post-transfusion (≤24 hours).
• Statistical analysis included Wilcoxon signed rank test, Spearman's rho correlation, and linear regression.

Main Results:

• Significant increases in tissue plasminogen activator (tPA) and antithrombin 3 (ATIII) levels post-transfusion (P≤0.012 and P≤0.011, respectively).
• Strong pre- to post-transfusion correlations observed for HsCRP, ATIII, tPA, and microparticles (MPs).
• Linear regression models showed significant associations between pre- and post-transfusion tPA and ATIII levels.

Conclusions:

• PRBC transfusions are associated with significant changes in tPA and ATIII levels in multi-transfused patients.
• These alterations suggest a coagulopathic response following PRBC administration.
• Further research is warranted to elucidate the clinical implications of these findings.
