Haematopoietic stem cell transplantation for primary immunodeficiencies has improved outcomes. Advances in donor selection and complication management now allow broader use of this treatment for severe immune deficiencies.

Area of Science:

  • Immunology
  • Hematology
  • Transplantation Medicine

Background:

  • Primary immunodeficiencies (PIDs) are a group of genetic disorders affecting the immune system.
  • Haematopoietic stem cell transplantation (HSCT) is a potentially curative treatment for many PIDs.
  • Historically, HSCT outcomes were limited by donor availability and complications.

Purpose of the Study:

  • To review current indications for HSCT in PIDs.
  • To assess the outcomes of HSCT in PIDs.
  • To highlight recent advancements influencing HSCT in PIDs.

Main Methods:

  • Review of recent literature on HSCT for PIDs.
  • Analysis of outcomes based on donor type and management strategies.
  • Evaluation of evolving indications for HSCT.

Main Results:

  • Significant improvements in HSCT outcomes for PIDs reported.
  • Successful use of alternative donors (unrelated, cord blood) and better complication management.
  • Expanded indications for HSCT in PIDs due to these advances.

Conclusions:

  • Related human leukocyte antigen-identical donors yield optimal results but are scarce.
  • Mismatched related donor transplants show promise, especially in infants, but immune reconstitution can be delayed.
  • Matched unrelated donor and cord blood transplants are now viable alternatives for all severe PIDs, improving outcomes with careful monitoring and preemptive treatment.
