Treatment of adrenoleukodystrophy with bone marrow transplantation.
Three children with adrenoleukodystrophy (ALD) underwent allogeneic bone marrow transplantation (BMT) between 1992 and 1993. The first boy had attention deficits, marked neuropsychological deficits and widespread demyelination in the frontal lobes on MRI before transplantation. Four years later he has mentally deteriorated and the demyelination on MRI has progressed. The second boy had no symptoms but had white matter lesions on MRI when diagnosed. He was regularly followed with MRI and neuropsychological investigations until BMT 18 months later. A progress of the lesions was noted on the initial MRI investigations, and 4 months before BMT a worsening of deficits in attention and kinaesthetic praxis could be observed. He rapidly deteriorated after the transplantation and died 18 months later. Both PCR and in situ hybridization confirmed the presence of donor cells in the brain. The third boy had no symptoms but white matter lesions on MRI when diagnosed. The neuropsychological tests remained normal but a slight progress was observed on MRI just before transplantation. This boy is still healthy 3.5 years after BMT. BMT as treatment for ALD has to be considered very early, even if a child without symptoms but signs of demyelination on MRI, if a suitable donor is available.
