NCT05981183

Brief Summary

The purpose of this pilot interventional study is to collect preliminary data on the application of a transcutaneous auricular vagal nerve stimulation (taVNS) device in patients with chronic kidney disease (CKD). This data will enhance understanding of the short-term safety, tolerability and effects of this novel therapeutic approach in the setting of CKD. The primary aims are to investigate the feasibility of the protocol and generate preliminary signals of efficacy and tolerability for two different doses of vagal nerve stimulation. The pilot estimates will be used to design a larger scale study that may lead to potentially targeted interventions to reduce cardiovascular (CV) mortality in the CKD population.

Outcome Measures

Primary Outcomes (2)

  • Heart Rate Variability (HRV) at Baseline

    HRV is the variation in the time interval between heartbeats.

    Day 1 (15 minutes prior to administration of intervention)

  • HRV at Post-Intervention

    HRV is the variation in the time interval between heartbeats.

    Day 1 (15 minutes Post-Intervention)

Secondary Outcomes (7)

  • Percentage of Participants with at least a 20% change in HRV from baseline to post-intervention

    Day 1 (Up to 15 Minutes Post-Intervention)

  • Blood Pressure at Baseline

    Day 1 (15 minutes prior to administration of intervention)

  • Blood Pressure at Post-Intervention

    Day 1 (15 minutes Post-Intervention)

  • Spontaneous Baroreceptor Sensitivity (BRS) at Baseline

    Day 1 (15 minutes prior to administration of intervention)

  • Spontaneous BRS at Post-Intervention

    Day 1 (15 minutes Post-Intervention)

  • +2 more secondary outcomes

Study Arms (2)

Intervention A

EXPERIMENTAL

Participants will receive 15 minutes of taVNS after an initial 15 minute rest-period and a 15 minute baseline measurement period. For participants assigned to Intervention A, the pulse width = 250 μs, and frequency = 50 Hz.

Device: Transcutaneous electrical nerve stimulation unit (TENS)

Intervention B

EXPERIMENTAL

Participants will receive 15 minutes of taVNS after an initial 15 minute rest-period and a 15 minute baseline measurement period. For participants assigned to Intervention B, the pulse width = 300 μs, frequency = 25 Hz.

Device: Transcutaneous electrical nerve stimulation unit (TENS)

Interventions

The TENS unit will be applied to participants' right ear at the cymba conchae. The dose is dependent on which arm (Intervention A or Intervention B) the participant is assigned to. Participants will undergo 15 minutes of vagal nerve stimulation.

Also known as: TENS Device 7000

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Individual 18-80 years of age with CKD stage 3-5 (eGFR \<60 mL/min/1.73m2) on most recent outpatient labs.

You may not qualify if:

  • Pacemaker dependent
  • Prisoners
  • Pregnant women. A pregnancy test will be offered if a subject is concerned about being pregnant.
  • Not capable of informed consent
  • Know autonomic function disorder (e.g. Parkinson's disease with autonomic dysfunction)
  • ICD or PPM precluding assessment of heart rate variability (e.g. chronic atrial fibrillation)
  • Recent myocardial infarction (4 weeks or less)
  • Maintenance dialysis
  • Epilepsy
  • Patients on labetalol (labetalol will interfere with catecholamine measurements)
  • Patients with diabetes
  • At least 50% of cohort must not be on beta blockers. This will help to distinguish the confounding effects of beta blockers.
