Predisposing factors for anti-D immune response in D − patients with chronic liver disease transfused with D + platelet concentrates

Abstract : Background: Recent reports have indicated that the risk of anti-D alloimmunization following D-incompatible platelet (PLT) transfusion is low in hematology and oncology patients. We investigated the rate of anti-D alloimmunization in RhD-negative (D- ) patients with chronic liver disease transfused with D+ platelet concentrates (PCs) and the factors involved, at a liver transplant (LT) center. Study design and methods: We reviewed the blood bank database from January 2003 to October 2016. D- patients who had received D+ PLT transfusions were eligible if they had undergone antibody screening at least 28 days after the first D+ PC transfusion, had no previous or concomitant exposure to D+ blood products, and had not received anti-D immunoglobulins. Results: Six of the 56 eligible patients (10.7%) had anti-D antibodies. All had received whole blood-derived PCs. Four of 20 patients (20%) untransplanted or transfused before LT and only two of 36 patients (5.6%) transfused during or after LT produced anti-D antibodies. These two patients were on maintenance immunosuppression based on low-dose steroids and tacrolimus. The factors identified as significantly associated with anti-D immune response were the presence of red blood cell immune alloantibodies before D+ PLT transfusion (p = 0.003), and D+ PLT transfusion outside the operative and postoperative (5 days) periods for LT (p = 0.023). Conclusion: D- patients with chronic liver disease transfused with D+ PLTs before LT are at high risk of developing anti-D antibodies. Preventive measures should be considered for these patients.
