    Background: Dendritic cells (DCs) are potent antigen-presenting cells critical for immunity. We previously demonstrated a significant association between pre-transplant blood myeloid dendritic cell (mDC) and plasmacytoid dendritic cell (pDC) deficiency and post-transplant BK viremia in renal transplant recipients. In the current post-hoc analysis, we studied the association of these same pre-transplant DC levels with other post-transplant outcomes. Methods: Pre-transplant peripheral blood mDC and pDC levels were quantified using flow cytometry in 78 patients undergoing kidney transplantation. Post-transplant outcomes were analyzed, including infection, rejection, and patient death, with a median follow-up of 5.3 years. Associations between DC levels and outcomes were assessed using logistic regression analysis and Cox proportional hazards models. Results: An independent association of mDC levels with post-transplant cytomegalovirus infection (adjusted odds ratio 7.0, P = 0.01) and patient death (adjusted hazard ratio 13.0, P = 0.015) was found. No associations were demonstrated between levels of either DC subtype and bacterial infections or rejection. Conclusions: Pre-transplant mDC deficiency is significantly associated with CMV infection and death after kidney transplantation.
