B Cell Activating Factor (BAFF) in Long-term Kidney Transplant Recipients Is Not a Prognostic Marker for Allograft Dysfunction or Survival

BAFF serum level is not related to anti-HLA sensitization, circulating memory B cells, plasmablast count, or allograft function. Circulating plasmablasts are associated with current allograft function but are not prognostic for future course.
