NCT02132013

Brief Summary

The purpose of this study is to evaluate the effects and efficacy of dietary sodium restriction by mean of a new healthcare approach in patients with chronic kidney disease. The test persons in the intervention group are actively supported to adhere to a restricted sodium diet with a structured self-regulation program to implement sodium recommendations that are in current guidelines.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Be 18 years or older.
  • Have chronic kidney disease (CKD stage 1-3, CKD 4 if eGFR is not lower than 25 mL/min/1.73m2, or be a renal transplant recipient.)
  • Have a urinary sodium excretion during at least the last 2 subsequent visits of more than 130 mmol per day, or one last urinary sodium excretion of more than 150 mmol per day.
  • Have a systolic blood pressure higher than 135 mmHg, diastolic blood pressure higher than 85 mmHg or a well-controlled blood pressure by treatment with antihypertensives including RAAS-blockade (ACE-inhibitor or ARB).
  • Sufficient command of the Dutch language.
  • Access and ability to use the internet.
  • Written informed consent.

You may not qualify if:

  • eGFR \< 25 ml/min/1.73m2 or an anticipated need for predialysis work-up within the time frame of the study.
  • Unstable disease: defined as rapid, persistent, progressive renal function loss (e.g. \> 6 mL/min/1.73m2 per year), not from acute, intermittent origin.
  • Blood pressure \> 170 mmHg systolic or \> 100 mmHg diastolic during medical treatment
  • Blood pressure \< 95 mmHg systolic not responding to withdrawal of antihypertensives.
  • Cardiovascular event (myocardial infarction, cerebrovascular accident) \< 6 months ago.
  • Renal transplantation \<1 year ago.
  • Medical conditions that are likely to interfere with completion of the study (such as progressive malignancy or other debilitating illness) at the discretion of the nephrologist.
  • Every patient who has participated in the ESMO study (regardless whether intervention or control) cannot participate in the current study.
  • Current participation in any clinical trial that might interfere with SUBLIME trial.
