Using a Transcutaneous Electrical Auricular Stimulator to Harness the Cholinergic Anti-Inflammatory Pathway (TEACAP)
February 20, 2024 updated by: Cynthia Aranow, MD, Northwell Health
Persistent chronic inflammation is an important underlying event in multiple diseases including rheumatoid arthritis, inflammatory bowel diseases and type 2 diabetes.
These disorders are characterized as inflammatory in part because of the important mediating role of pro-inflammatory cytokines in their pathogenesis.
This study will investigate whether transcutaneous auricular electrical stimulation of the vagus nerve will affect and decrease the inflammatory cytokine response in healthy individuals.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Vagus Nerve Stimulation
Device: Vagus nerve stimulation Patients will receive transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes.
|
Patients will receive transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes.
Blood will be withdrawn prior to stimulation and 1 hour following the stimulation.
The device is a handheld electrical pulse generator and a pair of electrodes to be placed at the ear for stimulation.
The specific target at the ear will be the auricular branch of the vagus nerve which innervates the skin of the ear canal.
Electrodes will be placed near/at the entrance to the canal of the ear to provide stimulation to the auricular branch of the vagus nerve.
|
Sham Comparator: Sham Vagus Nerve Stimulation
Patients will receive sham transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes.
|
Patients will receive sham transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes.
Blood will be withdrawn prior to stimulation and 1 hour following the stimulation.
Sham stimulation will be performed in the identical manner as true transcutaneous stimulation except that the patient will not receive electrical stimulation of the vagus nerve.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Lipopolysaccharide stimulated levels of TNF in whole blood.
Time Frame: 4 hours
|
Whole blood will be taken from patients and stimulated by lipopolysaccharide.
Levels of TNF produced by the cells in the whole blood after 4 hours of incubation will be measured.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Lipopolysaccharide stimulated levels of cytokines such as IL-1, IL-6, IL-8, IL-10 and HMGB1 in whole blood.
Time Frame: 4 hours
|
Whole blood will be taken from patients and stimulated by lipopolysaccharide.
Levels of cytokines such as IL-1, IL-6, IL-8, IL-10 and HMGB1 that are produced by the cells in the whole blood after 4 hours of incubation will be measured.
