[Two-chamber hemodiafiltration: comparison between exogenous reinfusion (PFD) and endogenous reinfusion (HFR)].
OBJECTIVE
This research aimed to compare two highly efficient dialysis techniques, paired filtration dialysis (PFD) and on-line hemodiafiltration with endogenous reinfusion (HFR) to evaluate the possible differences from a clinical, rehabilitative and managerial point of view.


METHODS
The study was carried out on 14 patients (aged 40-65 yrs) six patients underwent PFD and eight patients underwent HFR. Patients on PFD came from low-flux hemodialysis (HD), while patients on HFR came either from PFD (n=5) or from low-flux HD (n=3). The research was based on the evaluation of patients inverted exclamation mark parameters (depurative and biochemical, level of clinical, medical and social rehabilitation) and of management parameters (technological aspects, cost analysis and medical-legal issues).


RESULTS
HFR treatment improved plasmatic albumin values (> or =4.0 g/dL) and had a lower resistance to recombinant human erythropoietin (rHuEPO) therapy (by reducing the rHuEPO doses to reach the maintenance target values of hemoglobin (Hb) although both therapies resulted in equal depurative efficiency, and improved patient rehabilitation.


CONCLUSIONS
This preliminary research, which requires further confirmation, demonstrates that HFR seems to provide PFD with other positive benefits and offers the uremic patient a better life style.
