چکیده

OBJECTIVE To compare the frequency and type of neurological complications after bone marrow transplantation (BMT) with an HLA identical unrelated donor or a mismatched related donor (alternative donors) to the neurological complications after matched sibling BMT for standard and high risk leukaemia or myelodysplastic syndromes. METHODS Retrospective analysis of consecutively treated patients with (a) BMT from alternative donors (n=39), (b) treated with matched sibling BMT for standard risk leukaemia, myelodysplastic syndromes, or aplastic anaemia (n=53), and (c) treated with matched sibling BMT for high risk leukaemia, myelodysplastic syndromes, or aplastic anaemia (n=49). RESULTS A total of 72 neurological complications were found. Most of these occurred within the first 6 months after transplant. Thirty six patients developed a severe neurological complication: 17 Alternative donor patients (44%) by contrast with six standard risk patients (11%) and 13 high risk patients (27%; p<0.005). The most frequent complication was a metabolic encephalopathy occurring in 18% of patients. Most of the encephalopathies were caused by either the transplant procedure, cyclosporin, systemic infections, microangiopathic thrombopathy, or by complications induced by graft versus host disease. Infections of the CNS developed in 9% of patients, cerebrovascular lesions in 3%. CONCLUSIONS Severe neurological complications are more frequent after BMT from alternative donors. This is mainly due to increased treatment related morbidity and to more profound immunosuppression after BMT from alternative donors.

ALLOGENIC BONE MARROW TRANSPLANTATION IN APLASTIC ANEMIA

Eighteen patients, twelve men and six women, with aplastic anemia underwent allogenic bone marrow transplantation (BMT) from HLA-matched siblings during the period of 1990 to 1996. The conditioning regimen was cyclophosphamide with or without busulfan, depending on the cause of aplasia. Antilymphocyte globulin (ALG) and cyclosporine were used for rejection and acute GVHD prophylaxis, respe...
