Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background: Incremental hemodialysis (HD) is a starting regime for renal replacement therapy (RRT) adapted to each patient's necessities. It is mainly conditioned by the residual renal function (RRF). The frequency of sessions with which patients start HD -one or two sessions per week-, is lower than that for conventional HD three times per week. Such frequency is increased (from one to two sessions, and from two to three sessions) as the RRF declines.

Methods/Design: IHDIP is a multicenter randomized experimental open trial. It is randomized in a 1:1 ratio and controlled through usual clinical practice, with a low intervention level and non-commercial. It includes 152 patients older than 18 years with chronic renal disease stage 5 and start HD as RRT, with a RRF of ≥ 4ml/min/1.73m2, measured by renal clearance of urea (KrU). The intervention group includes 76 patients who will start with one session of HD per week (incremental HD). The control group includes 76 patients who will start with three sessions per week (conventional HD). The primary purpose is assessing the survival rate, while the secondary purposes are the morbidity rate (hospital admissions), the clinical parameters, the quality of life and the efficiency.

Discussion: This study will enable us to know with the highest level of scientific evidence, the number of sessions a patient should receive when starting the HD treatment, depending on his/her RRF.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Conventional thrice-weekly HD for 3 to 5 hours in a health center in an outpatient basis is the most used renal replacement therapy (RRT) regimen (1). However, it has an unacceptable high mortality rate (10%-20% a year). In order to try to improve those results, new regimens have been proposed. They are based on an increase of the HD dose and/or a higher number of sessions (2). Nevertheless, inconsistent results in terms of clinical benefits with such programs have been shown in recently published randomized and controlled trials (3,4), together with a lower rate of vascular access success (5) and a lower maintenance of the RRF (6) The National Kidney Foundation-Kidney Disease Outcomes Quality Initiate (NKD KDOQI 2015)(1) 2015 guidelines allow the reduction in the weekly HD dose for patients with a residual kidney urea clearance (KrU) higher than 3ml/min/1.73m2. In these cases, the renal clearance (Kr) is added to the dialysis clearance (Kd) obtained in 2 sessions per week, thus obtaining the adequate dialysis dose (7,8) Surprisingly enough, few centers follow this recommendation when over 50% of patients start HD with KrU \>3 mL/min (9).

Authors like Kalantar-Zadeh et al (9,10) in the U.S.A. or Teruel et al (11) in Spain have published their experience with 2 HD sessions per week in incident patients. Through this regime they have shown that the RRF is preserved and the survival rate is similar to the one obtained with the conventional HD. This is due to the fact that the Kr has much greater clinical weight than Kd7, since the RRF contributes to the production of vitamin D and erythropoietine (12,13), and eliminates the protein-bound uremic toxins that are poorly dialyzed (13,14). In other words, the RRF plays a fundamental role both in the dialysis adequacy and in survival (15,16).

Currently, some authors are questioning the number of HD sessions with which a patient should start the renal replacement therapy (RRT) (7, 17-19). Progressive HD is an initiation regimen adapted to the patient's RRF. The frequency increases as the daily diuretic level declines (7, 17-19).

The IHDIP trial20 aims at determining whether or not starting with one HD session per week reduces mortality in incident patients and its influence in morbidity (hospital admissions), clinical parameters, quality of life and efficiency with regard to the patients who start RRT with the conventional method.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

This is a prospective, multicenter, randomized clinical trial. It has two strata: for age (≥or\< 75 years old) and for KrU (≥or\< 5,5 ml/min/1.73m2). It is controlled through usual clinical practice.

Intervention consists in reducing the frequency or number of sessions per week with which patients start the HD treatment. The experimental group will start with one session/week, then the number of weekly sessions will be increased to two and later to three as per criteria for progression.
