Intradialytic symptomatic hypotension [ Time Frame: all dialysis sessions, three per week, for 2 years ]
Intradialytic symptomatic hypotension was defined as a rapid symptomatic fall of the systolic blood pressure by at least 30 mmHg or that required nursing and/or medical intervention

  • Resistance to erythropoiesis-stimulating agents [ Time Frame: Monthly for 2 years ]
    Resistance to erythropoiesis-stimulating agents was measured as (EPO therapy in IU/week)/(Hb in g/dL*body wheight in kg)
  • Calcium-phosphate metabolism [ Time Frame: Monthly for 2 years ]
    Outcome measures: phosphatemia, calcemia and PTH

Effects of Convective Therapies in Dialysis Patients
Effects of Convective Therapies in Dialysis Patients

Convective therapies have been proposed for improving chronic dialysis patient outcomes, including intradialytic symptomatic hypotension.

To evaluate the frequency of sessions with intradialytic symptomatic hypotension in different types and doses of convective therapies compared with low-flux hemodialysis (HD), the investigators performed a multicentre, open-label, randomized controlled trial.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Procedure: online pre-dilution hemofiltration
