Background: Therapeutic granulocyte transfusion remains an indication for neutropenic sepsis associated with prolonged neutropenia. However, harvest complexity and lack of proved efficacy mark the limits of its development.
Case report: A 58-year old man received allogeneic stem cell transplantation for osteomyelofibrosis. Six months later, after a transplant rejection, he presented with perineal cellulitis from hemorrhoid origin, without any microbiological documentation. The evolution was unfavorable despite antibiotic and antifungal therapy. A set of seven granulocytes transfusions was initiated. Re-circulation of granulocytes analysis showed an initial increase (H2) followed by a decrease (H8) reaching the basal rate at H16. No toxicity has been reported during or following the transfusions. Clinical improvement has been reported five days after the first transfusion, scaring over at D15, without any neutrophil recovery.
Conclusion: In 2014, granulocyte transfusion therapy is indicated for severe infection associated with long-term neutropenia. Minimal circulation of transfused cells in our observation and fast clinical improvement suggest the concentration of granulocytes on the infected area.
