Umbilical Cord Blood Transplantation Provides Effective Alternative for Patients with Chronic Granulomatous Disease

Strategic Insights -

Researchers from the National Cancer Institute (NCI) have presented a study on the effectiveness of umbilical cord blood transplantation (UCBT) for patients with chronic granulomatous disease (CGD) who lack suitable HLA-matched donors. The study, published in Transplantation and Cellular Therapy, found that UCBT can provide an effective alternative for these patients, with a high rate of success in resolving disease and decreasing infection risk.

Key Takeaways:

  • 39 patients with CGD underwent UCBT at Primary Immune Deficiency Treatment Consortium (PIDTC) centers between 2001 and 2019.
  • The median age at receipt of UCBT was 2.1 years, and most patients (87%) received UCB from unrelated donors.
  • High infection burden (1.72/person years) and inflammatory disease (38%) were common in the year pre-UCBT.
  • Neutrophil and platelet recovery occurred at a median of 18 and 38 days, respectively, with 9 patients experiencing early graft failure.
  • 28 patients were alive at a median follow-up of 4.28 years, and estimated 3-year overall and event-free survival were 73.7% and 56.2%, respectively.
  • No identifiable factors, including history of infection or inflammatory disease, were associated with graft failure or survival.
  • Infections decreased with time post-UCBT, and pre-existing inflammatory disease resolved in all surviving patients.

Statistics:

  • 1.72 infections/person years
  • 38% prevalence of inflammatory disease in the year pre-UCBT
  • 18 days median neutrophil recovery
  • 38 days median platelet recovery
  • 28 patients alive at a median follow-up of 4.28 years
  • 73.7% estimated 3-year overall survival
  • 56.2% estimated 3-year event-free survival
