An unrelated donor bone marrow transplant (UD-BMT) was carried out on a 10-year-old patient with metachromatic leukodystrophy (MLD). We collected cerebrospinal fluid (CSF) on day +168 and cultured it with recombinant IL-2 and PHA-P to examine the origin of cells in the CSF. Analysis on variable number of tandem repeat (VNTR) of lymphocytes in the CSF amplified by PCR revealed that lymphocytes in the CSF were of donor origin. These data support that BMT at an early stage may prevent deterioration in MLD. Although the patient developed grade III acute GVHD with rash and diarrhea, we successfully treated acute GVHD using rabbit anti-human thymocyte immunoglobulin (ATG). UD-BMT may be an alternative treatment for patients with MLD in the absence of an HLA matched family donor.

Four children with metachromatic leukodystrophy (MLD) underwent allogeneic bone marrow transplantation between 1988 and 1993. No effect on the natural course of the disease was observed in two children with late infantile and juvenile MLD. They had moderate neurological symptoms at the time of BMT and were followed for 7 and 6 years, respectively. The third child with the juvenile form of MLD was mildly to moderately affected when transplanted. She had lost some gross motor functions as well as speech and mental abilities at follow-up 3 years later. The fourth case, diagnosed biochemically and presymptomatically as late infantile MLD, had a subtle gait disturbance when grafted at 18 months of age. Demyelination, not observed before BMT, was visualized 1 year later on MRI. This boy's condition has continued to deteriorate 2 years after transplantation. We have adopted recent recommendations that BMT should be considered only in presymptomatic children with late infantile MLD or early in the course of juvenile MLD. In such children, still longer follow-up periods are necessary to evaluate the benefit of BMT.

From 1986 to June 2000, sixty children suffering from acute and chronic leukemia (n = 42, 33 of which in resistant relapse), genetic diseases (n = 11), aplastic anemia (n = 2, one of which with platelet refractoriness and bleeding), myelodysplasia (n = 5) received an haploidentical bone marrow, mismatched for 2-3 HLA loci. The donor's marrow was treated in vitro with vincristine and methylprednisolone to obtain a functional T depletion (MLC and CTL inhibition, functional blockade of Th1 and Th2). The prevalence of infectious complications and GVHD was similar to that recorded in matched unrelated donor (MUD) transplants. In situations of high risk of rejection (chronic leukemia, genetic diseases) we infused immediately one half of the harvest and then frozen aliquots from the second week. Of the 25 ALL and 8 AML in resistant relapse, 3 survived, disease-free at 14, 8 and 1 years respectively. Of the 3 ALL, transplanted during remission, 1 is surviving at 18 months. Of the 6 CML, 1 had fractionated bone marrow and is surviving at 3 years, and 5 had standard single dose infusion and died of progression of their disease after rejection of the graft (4) or blast crisis after complete engraftment (1). The 2 patients with aplastic anemia, those with myelodysplasia, and 6 of the 10 with genetic disorders died of transplant-related complications or disease progression. 4 patients with osteopetrosis (n = 2), MLD (n = 1), Wiskott Aldrich dis. (n = 1) survive at 8, 2, 5 and 1.5 years respectively. In patients transplanted with fractionated marrow GVHD > 2nd grade occurred in 15%. Only one patient rejected the graft. Compared with MUD transplantation, mismatched BMT whenever performed in patients in good conditions provides similar outcome and widens the donor availability.
