Chediak Higashi Syndrome

Unrelated donor marrow transplantation was undertaken in eight infants with severe combined immunodeficiency (SCID) and two children each with Wiskott-Aldrich syndrome (WAS) and Chediak-Higashi syndrome (CHS) who did not have histocompatible siblings. Donors for three patients were phenotypically matched at all HLA-A, B, Dr, and Dw loci, whereas nine donors were mismatched from the recipients at one of the HLA-A or B loci but phenotypically identical at evaluable D loci. All but one patient received conditioning chemotherapy and/or radiotherapy before infusion of donor marrow, which was not T-cell depleted. Prophylaxis for graft-versus-host disease (GVHD) consisted of methotrexate and prednisone combined with either cyclosporine A (six patients), antithymocyte globulin (five patients), or anti-CD5 ricin A chain immunotoxin (one patient). All patients engrafted with donor cells, and only 4 of 12 experienced any GVHD (1 of 8 SCID, 1 of 2 WAS, 2 of 2 CHS). Two children who developed grade II and two who developed grade III GVHD were successfully treated and all are now alive, off immuno- suppressive therapy, with no evidence of chronic GVHD greater than 18 months after transplant. Ten patients are alive with excellent immunoreconstitution greater than or equal to 1 year to greater than or equal to 3 years after transplant; actuarial survival is predicted to be 83% with a median follow-up of 2 years. Two children with SCID succumbed to pre-existing opportunistic infection early posttransplant. We conclude that closely matched unrelated donor bone marrow transplantation can correct congenital immunodeficiencies including variants of SCID, WAS, and CHS, with an acceptably low incidence of transplant-related complications, principally GVHD.

Donor Bone Marrow

PURPOSE To test the use of unrelated donor bone marrow transplantation (URD BMT) to cure children with high-risk acute leukemias. PATIENTS AND METHODS Between June 1985 and December 1994, 50 children with acute leukemia (15 acute myelogenous leukemia [AML], 35 acute lymphoblastic leukemia [ALL]; 22 greater than second complete remission [CR]) received BMT from a URD at the University of Minnesota. Ages ranged from 0.9 to 17.5 years (median, 8.8). Median follow-up is 2.1 years (range, 1 to 7.3). Thirty patients (60%) received bone marrow fully matched at HLA-A,B and DRB1; 20 (40%) received bone marrow with a major or minor mismatch at a single HLA-A or B locus. RESULTS The median time to neutrophil engraftment was day 24 (range, 14 to 42 days) in those receiving matched and day 25 (range, 15 to 32 days) in those receiving mismatched marrow (P = .35). The incidence of grades III to IV graft-versus-host disease (GVHD) was 23% (95% confidence interval [CI], 7% to 39%) in matched and 32% (95% CI, 8% to 52%) in HLA-mismatched patients (P = .57). The incidence of chronic GVHD was 50% (95% CI, 28% to 72%) in matched and 57% (95% CI, 23% to 91%) in mismatched patients (P = .80). Disease-free survival for patients with ALL is 37% (95% CI, 21% to 53%) at 1 year and 30% (95% CI, 15% to 46%) at 2 years; for patients with AML, 53% (95% CI, 28% to 78%) at 1 year and 33% (95% CI, 6% to 60%) at 2 years. CONCLUSION URD BMT is an effective treatment for children with poor-prognosis acute leukemia and should be considered for all high-risk patients. Early referral of patients is strongly recommended.

Late Morbidity

Abstract Chronic graft-v-host disease (chronic GVHD) is a frequent cause of late morbidity and death after bone marrow transplantation (BMT). The actuarial survival after onset of chronic GVHD in 85 patients was 42% (95%Cl = 29%, 54%) at 10 years. Baseline characteristics present at the onset of chronic GVHD (before therapy) in 85 patients were reviewed to determine which were risk factors for death. In a multivariate proportional hazards analysis, three baseline factors emerged as independent predictors of death: progressive presentation (chronic GVHD following acute GVHD without resolution of acute GVHD; hazard ratio of 4.1, 95% Cl = 2.1 to 7.8), lichenoid changes on skin histology (hazard ratio of 2.2, 95% Cl = 1.1 to 4.3), and elevation of serum bilirubin greater than 1.2 mg/dL (hazard ratio = 2.1, 95% Cl = 1.1 to 4.1). Actuarial survival of 23 chronic GVHD patients with none of these risk factors was 70% at 6 years (95% Cl = 38%, 88%). Thirty-eight patients with one of these risk factors had a projected 6-year survival of 43% (95% Cl = 21%, 63%). The 29 patients with any combination of two or more of these factors had a projected 6-year survival of only 20% (95% Cl = 8%, 37%). Identification of baseline risk factors should facilitate design of trials of chronic GVHD therapies and assignment of high-risk patients to more aggressive innovative therapeutic regimens.
