The immune reactivity of allogeneic lymphocytes plays a major role in the control of leukemia after bone marrow transplantation. In patients with recurrent leukemia after marrow transplantation, chimerism and tolerance provide ideal conditions for adoptive immunotherapy with donor lymphocytes. We studied the effect of donor lymphocyte transfusions on acute and chronic leukemia in relapse after bone marrow transplantation. One hundred thirty-five patients with chronic myeloid leukemia (CML) (N = 84), acute myeloid leukemia (AML) (N = 23), acute lymphoblastic leukemia (ALL) (N = 22), myelodysplastic syndrome (MDS) (N = 5), and polycythemia vera with osteomyelofibrosis (PCV) (N = 1) were treated with transfusions of donor lymphocytes. Patients were monitored for response of leukemia, including in CML, the use of the polymerase chain reaction for bcr/abl mRNA transcripts and for the occurrence of graft-versus-host disease (GVHD) and myelosuppression. Complete remissions were induced by donor lymphocyte transfusions in 54 patients with CML (73%) and in the patient with PCV; complete remissions were also induced in five patients (29%) with AML and a patient with MDS. In contrast, ALL did not respond to adoptive immunotherapy with donor lymphocyte transfusions. Remissions were durable in patients treated for CML in chronic phase (probability of remission: 87% at 3 years). Lymphocyte transfusions were also given to 18 patients with ALL, AML, MDS, and transformed phase CML who were in remission after chemotherapy. These remissions were not durable. Fifty-two patients (41%) developed GVHD of grade 2 or more, and 41 patients (34%) showed signs of myelosuppression. Seventeen patients died without leukemia, 14 patients with GVHD and/or myelosuppression. Donor lymphocyte transfusions exert strong effects against myeloid forms of leukemia and induce durable remissions in CML.

Invasive mold infections are a threat to immunosuppressed patients such as patients with graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (SCT). Up to 10% of SCT recipients develop invasive aspergillosis (IA). Invasive zygomycosis (IZ) may occur during treatment against IA. Here we report 4 SCT patients with GVHD diagnosed with IZ. All patients had received myeloablative hematopoietic SCT and developed chronic GVHD requiring systemic immunosuppression. Underlying diseases were acute lymphocytic leukemia (2), osteomyelofibrosis, and multiple myeloma. All patients had developed pulmonary infiltration that led to initiation of antifungal therapy. Treatment for IA was voriconazole, caspofungin, or itraconazole. Organs involved with zygomycosis were lung, nasal sinus, skin, and kidney. Treatment with liposomal amphotericin and posaconazole was initiated in all patients, and 2 patients also had surgical debridement as well. Despite intensive treatment, no patient survived. IZ is becoming more common in patients with GVHD on successful treatment for IA. Even non-specific symptoms are suspicious in this group of patients and need to be evaluated by vigorous diagnostics. Despite effective antifungals and surgical intervention, the prognosis is grim in patients with active GVHD, as immunoreconstitution is mandatory for successful management.

Donor lymphocyte infusion (DLI) is used to prevent or treat haematological malignancies relapse after allogeneic stem cell transplantation (allo-SCT). Recombinant human granulocyte colony-stimulated factor primed DLI (gDLI) is derived from frozen aliquots of the peripheral blood stem cell collection. We compared the efficacy and safety of gDLI and classical DLI after allo-SCT. We excluded haploidentical allo-SCT. Initial diseases were acute myeloblastic leukaemia (n = 45), myeloma (n = 38), acute lymphoblastic leukaemia (n = 20), non-Hodgkin lymphoma (n = 10), myelodysplasia (n = 8), Hodgkin lymphoma (n = 8), chronic lymphocytic leukaemia (n = 7), chronic myeloid leukaemia (n = 2) and osteomyelofibrosis (n = 1). Indications for DLI were relapse (n = 96) or pre-emptive treatment (n = 43). Sixty-eight patients had classical DLI and 71 had gDLI. The response rate was 38.2%, the 5-year progression-free survival (PFS) rate was 38% (29-48) and the 5-year overall survival (OS) rate was 37% (29-47). Graft versus host disease rate was 46.7% and 10.1% of patients died from toxicity. There were no differences between classical DLI and gDLI in terms of response (p = 0.28), 5-year PFS (p = 0.90), 5-year OS (p. 0.50), GvHD (p = 0.86), treated GvHD (p = 0.81) and cause of mortality (p. 0.14). In conclusion, this study points out no major effectiveness or toxicity of gDLI compared to classical DLI.
