Granulocyte transfusions collected after steroid priming for severe infections during neutropenia: A single center experience

Abstract Background There is no universally accepted opinion on the use of granulocyte transfusions collected using apheresis (GTA) in neutropenic patients and severe infection. Patients and methods The efficacy and safety of GTAs transfused at a single center over 10 years were analyzed retrospectively. GTAs were harvested from voluntary unrelated donors after priming with methylprednisolone using continuous apheresis and hydroxyethylstarch as sedimentation agent. Results 41 patients with neutropenia and hematologic malignancy (15 females and 26 males aged 22–69 (median 45.5)) were given a median 3.5 GTAs per patient (range: 1–17) containing a median 1.39 × 10 10 granulocyte/GTA (range: 0.65–2.81). The indications for GTA use were soft tissue inflammation, sepsis, and pneumonia in 30, 22, and 14 cases, respectively. After GTA complete (30 patients: 73.2%) or partial (6 patients: 14.6%) healing of the infection was achieved. The success rate was 91.7% in soft tissue infections, 66.7% in invasive fungal infections, and 68% in sepsis. Septic shock (documented in 12 cases) was associated with a poor response ( P Conclusions In our study GTAs collected after steroid priming and used for the treatment of infection during severe neutropenia have shown comparable efficacy with several previously reported trials. However retrospective fashion of our study and inhomogeneous group of patients do not allow any firm conclusions. Prospective studies (including patients’ registries) are needed for the better clarification of the role and the dose of GTAs necessary for the successful infection management during neutropenia.
