Bone marrow transplantation was performed on an 8-month-old boy who was diagnosed as having fucosidosis following the diagnosis of the disease in his older brother. Although he was asymptomatic and his development was normal, abnomalities were found on an MRI scan prior to transplant. In the absence of a suitable related donor, an unrelated volunteer donor was used. Conditioning for the transplant consisted of busulphan and cyclophosphamide. Graft-versus-host disease prophylaxis consisted of in vitro T cell-depletion of the bone marrow and in vivo administration of cyclosporin. The post-transplant period was complicated by moderately severe graft-versus-host disease. Engraftment was documented by the presence of donor levels of alpha-fucosidase, donor blood group and tissue type (difference in the DQ antigen), and chromosomal polymorphism pattern of donor origin. Eighteen months after transplant, there is evidence of mild neurodevelopmental delay. By contrast, his elder sibling showed far greater developmental delay at the same age. The patient's MRI scan shows improvement. We believe this to be the first case of human fucosidosis treated by bone marrow transplantation.

Fucosidosis is a rare autosomal recessive lysosomal disorder caused by alpha-fucosidase deficiency. We report a child with fucosidosis, second daughter of non-consanguineous parents, for whom biochemical diagnosis followed clinical evidence of the disease in her older sister. Based on previous experiences, the indication to transplant was considered. Since she lacked a matched sibling, an unrelated marrow donor was found. At pre-hematopoietic stem cell transplantation evaluation, first signs of neurological involvement were clinically detectable. MRI showed diffuse hypomyelination and auditory brainstem responses and somatic-sensorial evoked potentials were altered. Visual evoked potentials were normal, tortuosity in the retinal veins and peripapillary hemorrhages were detected. Bone marrow transplantation conditioning was with a regimen of busulphan, thiotepa and cyclophosphamide; in vivo Campath 1G, cyclosporin A and short course methotrexate were given to prevent graft-versus-host disease. The patient engrafted rapidly and her post-transplant course was complicated by moderate graft-versus-host disease, transient episodes of idiopathic thrombocytopenic purpura, repeated septic complications and recurrent episodes of Sweet's syndrome. Sequential short tandem repeat polymorphisms on peripheral blood and bone marrow cells documented the persistence of donor engraftment. Follow-up showed a progressive rise of enzymatic levels. Psychomotor development improved, as confirmed by evaluation of evoked potentials and by MRI scanning.
