- We describe outcomes after allogeneic transplantation in 34 patients with dyskeratosis congenita transplanted between 1981 and 2009. The median age at transplantation was 13 years (range 2 - 35). Approximately 50% of transplants were from related donors. Bone marrow was the predominant source of stem cells (n=24/34). The day-28 probability of neutrophil recovery was 73% and the day-100 platelet recovery was 72%. The day-100 probability of grade II-IV acute GVHD and the 3-year probability of chronic GVHD were 24% and 37%, respectively. The 10-year probability of survival was 30%; 14 patients were alive at last follow-up. Ten deaths occurred within 4 months from transplantation due to graft failure (n=6) or other transplant-related complications; 9 of these patients had been transplanted from mismatched related or from unrelated donors. Another 10 deaths occurred after 4 months; 6 of them occurred more than 5 years from transplantation, 4 of these were attributed to pulmonary failure. Transplant-regimen intensity and transplants from mismatched related or unrelated donors were associated with early mortality. Transplantation of grafts from HLA-matched siblings with cyclophosphamide-containing non-radiation regimens was associated with early low toxicity. Late mortality was attributed mainly to pulmonary complications and likely related to the underlying disease.
