PURPOSE OF REVIEW: Kidney transplantation remains the treatment of choice for patients with end-stage renal failure. However, despite significant advancements in detection of donor-specific human leukocyte antigen antibodies, improved immunosuppression and patient management, the durability of this life-saving therapy has not improved. This results in increased morbidity and mortality as well as increased cost to the healthcare system.
RECENT FINDINGS: The identification of immune-pathogenic pathways responsible for allograft failure coupled with targeted interventions will represent one of the most important future objectives of transplant immunologist and physicians. The development of sensitive donor-specific antibody (DSA) detection techniques and advancements in renal allograft pathology assessments have revealed the importance of humoral immunity in mediating allograft failure. This is especially true for complement activating DSAs (C1q+).
SUMMARY: Our current understanding suggests that reduction of immunosuppressive medications or medication nonadherence is now the major causes of DSA development and attendant pathology. Other important factors in initiation of de-novo DSA production include viral infections, human leukocyte antigen-DR/DQ mismatches and autoimmune diseases. Therapies aimed at antibody reduction, B-cell depletion and modification of the complement system will likely usher in new therapeutic approaches for prevention and treatment of DSA-mediated allograft dysfunction.
