RESUMO

Neurological complications are not usually considered among the most important complications that may appear after allogeneic bone marrow transplantation (BMT). We have analyzed the occurrence of neurological manifestation in 27 recipients of allogeneic BMT. Ten patients (37%) developed neurological symptoms, and 14 episodes were registered. The most frequent manifestations were due to the use of cyclosporin A or prednisone for prophylaxis or treatment of graft-versus-host disease (GVHD). Cerebrovascular events (infarction or hemorrhage) and CNS infections were the most severe complications: they represented 26% of cause of death in our series. In conclusion, neurological complications are frequent in these patients, and represent an important cause of morbidity and mortality.

RESUMO

An allogeneic transplantation of CD34(+)-selected cells from peripheral blood (allo-PBT/CD34(+)) from HLA-identical sibling donors was performed in 50 adult patients with acute myeloid leukemia in first complete remission (AML CR1) (n = 29), myelodysplastic syndrome (MDS) (n = 4), or chronic myeloid leukemia in first chronic phase (CML CP1) (n = 17). Clinical results were compared to a concurrent group of 50 patients transplanted with unmodified peripheral blood progenitor cells (allo-PBT), matched for age, diagnosis, and disease stage. The median follow-up period was 29 months (range 1-69). The actuarial probability of developing acute GVHD clinical grade II to IV was 16% (95%CI: 6-26) for the allo-PBT/CD34(+) group and 41% (95%CI: 29-57) for the allo-PBT group (P = 0.002). The actuarial probability of developing extensive chronic GVHD was 22% (95%CI: 8-36) for the allo-PBT/CD34(+) group and 47% (95%CI: 31-63) for the allo-PBT group (P = 0.02). Recipients of allo-PBT/CD34(+) had less toxicity associated with the transplant and better Karnofsky index at the last follow-up. For AML/MDS patients, the actuarial probability of disease-free survival (DFS) for recipients of allo-PBT/CD34(+) and allo-PBT was 65% (95%CI: 45-85) vs43% (95%CI: 28-58) (P = 0.05), respectively. These data provide a rationale for a randomised trial of allo-PBT/CD34(+) vs allo-PBT in AML/MDS patients in early stage of the disease.
