Infection is a leading cause of death in hemodialysis patients, partly due to dysfunctional immunity. Frequent dialysis therapy improves patient outcomes and quality of life. We hypothesize that extended home hemodialysis (EHHD) also improves immune function compared to conventional in-hospital hemodialysis (CHD); therefore, we designed a prospective matching-cohort clinical study to assess serum inflammatory markers and the functional capacity of monocyte-derived dendritic cells (MDDCs) and T-lymphocytes. Serum CRP was decreased in EHHD patients suggesting that extended dialysis may decrease inflammatory solute/cytokine levels. Compared to controls, MDDCs from hemodialysis patients had similar endocytic capacity, expression of co-stimulatory molecules, and T-cell activation capacity. However, CHD was associated with the highest expression of CD83 and CD40. Activated T-cells in CHD patients also produced significantly more immunosuppressive IL-10 compared to EHHD patients and controls. Therefore, EHHD may improve immune function by decreasing inflammation, MDDC pre-activation, and synthesis of immunosuppressive cytokines.
