  1. The Good, The Bad and the … Old(?):Making Sense of the Red Cell Age Debate Daniel N. Cohen, M.D.,Ph.D. Vanderbilt University Medical Center Department of Pathology 26 July 2013 : [31 August 2010]

  2. Importance of Transfusion Medicine • Every 2 seconds someone in the U.S. needs blood • 14,650,000 PRBCs in 2007. • 30,000,000 all transfused products • 5,000,000 recipients • U.S. population eligible to give blood… • Less than 38%

  3. Public attention Tennessean, 28 July 2010

  4. Challenges to Transfusionof Red Cells • Red cell storage lesion: Biochemistry, structural biology • Current data • Trials recruiting • Future directions • Future challenges • Pt safety, economics, EBM

  5. Quality of Evidence Based Medicine 1. Meta-Analysis 2. Systematic Review/Guideline 3. Randomized Controlled Trial 4. Cohort Study 5. Case Control Study 6. Case Series/Case Report 7. Animal Research/Lab Data 8. Anecdote, epiphenomenalism Modified from, BA Sastre, VUMC & hiru.mcmaster.ca/ebm

  6. A spark • 6000+ pts studied, Cincinnati, – retrospective observational, mortality index, complications, no biochemical ends.

  7. Koch et al. 2008 ↑ Complications Koch et al 2008, NEJM

  8. Koch et al. 2008 ↑Mortality Koch et al 2008, NEJM

  9. Koch et al. 2008 Complications

  10. Koch et al. 2008 The Rub – W.S. Koch et al 2008, NEJM

  11. Koch et al. 2008 The Conclusions • Adamson JW editorial (NEJM 2008) • 1) Generalizable? The median age of the patients in the study was 70 years , defined w/coexisting illnesses. • 2) The surgery required cardiopulmonary bypass. Bypass machine and red cells interaction? particularly deleterious if the red cells have been stored for 3 or 4 weeks, instead of 1 or 2? What about no bypass? • 3) Second, in any surgical setting, would the complete avoidance of blood transfusions (or as complete as possible) lead to even better outcomes?

  12. Current Data ~45 observational, retrospective studies (Cardiac surgery, critical care, trauma, colorectal surgery.) Problems for all (confounders): • Transfusion volume ≈ worse outcomes (underlying clinical factors) • ↑ volume, ↑ likelihood of older units • ø randomization, ø r/o confounders (unrecognized or recognized) • No std def. “storage duration” • Mean ([2+40]/2 = 21)?, Max?, proportion (>14d ↓DPG)? • Leukoreduced vs not – unknown clinical signif. • Primary endpoints and analysis plan (w/ 2º analysis) defined PRIOR and stated in publication. Avoid post hoc (cherry picking)

  13. The Storage “Lesion” • Metabolic • ↓pH ↑H+, ↓ATP ↓GTP, ↓DPG, ↓GSH, ↓NADH, ↓ NADPH • Enzymatic (↓ w/leuko) • Loss surf. Glycans (sticky) • Lysolipids • Protein damage • Oxidative • Band III damage* • Decoration of proteins (B9 and neo-Ag) • HgbA1C vs. ε-lysines • Oxidized lipids – micro vesicles – inflammatory trigger • Lysolipids – TRALI – neutrophil priming • Physiologic • Shape change (↓ deformability, ↓ capillary flow) • Membrane loss (PS) • Lysis (apoptosis, etc.) Right Rise ↑[H+]= ↓pH Adapted from: Hess Transf & Aphersis Sci. 2010 *Band III binds PS and PIP2

  22. ARIPI Study Design 2009 Fergusson D, et al.2009. Transfus Med Rev. 23(1):55-61

  23. ARIPI Study Execution 2012

  24. ARIPI 2012 JAMA • 6 Canadian institutions • May 2006- June 2011 • 377 children • 189 standard RBC issue • 188 fresh <7 days • Death, BPD, retinopathy, NEC, IVH • Monitoring for >90 days after stay

  25. ARIPI Design and Stats • 450 infants to detect 0.05% difference 80% power (2-tailed) with absolute decrease 15% • Assumption 10% non-compliance • IRB approved • Readjusted sample size to 372 with interim analysis (non-compliance 4%)

  26. ARIPI Distrubtion groups • Avg. age of each individual transfusion & • Weighted avg. age by volume transfused • Mean 5.1 d Mean 14.6 d Fergusson et al JAMA. 2012;308(14):1443-1451.

  27. ARIPI Transfusion Data Fergusson et al JAMA. 2012;308(14):1443-1451.

  28. ARIPI: Primary Outcomes Fergusson et al JAMA. 2012;308(14):1443-1451.

  29. ARIPI: Infectious outcomes Fergusson et al JAMA. 2012;308(14):1443-1451.

  30. ARIPI: Conclusions • In conclusion, the transfusion of fresh RBCs did not improve clinical outcomes in high-risk, premature, very low-birth-weight infants. We thus do not recommend any changes to storage time practices for the provision of RBCs to infants admitted to neonatal intensive care.

  31. Conclusions • RECESS, ABLE, INFORM – In progress • Deoxygenation of pRBCs reduces the storage lesion • Red Blood cell age does not influence low birthweight neonatal infectious outcomes Is the storage lesion clinically significant?
