Clinical Trial Summary

The purpose of this study is to determine if nVNS will decrease autonomic symptom intensity (COMPASS-31 and Child Functional Disability Inventory) in adolescent patients with postural orthostatic tachycardia syndrome (POTS) in comparison to standard recovery STEPS management.


Description:

Project purpose: The investigators will study the use of non invasive vagal nerve stimulation in newly diagnosed adolescent patients with POTS to see if symptom management improves over 2 months. Surveys will include COMPASS-31. Child Functional Disability Inventory, and PHQ-9. Patient logs will evaluate headache frequency, exercise duration and VNS use. Research objectives: The investigators hypothesize that: Primary Aim 1. Use of noninvasive vagal nerve stimulation will decrease autonomic symptom intensity compared to control group. Primary Aim 2. Use of noninvasive vagal nerve stimulator will improve child function. Primary Aim 3. Heart rate elevation measured by head up tilt table test will decrease in the treatment group compared to the control group. Secondary goals include: Secondary Aim 1: To determine if utilization of noninvasive vagal nerve stimulation influences headache frequency Secondary Aim 2: Determine if utilization of noninvasive vagal nerve stimulation will influence weekly duration of aerobic exercise. Secondary Aim 3: Determine if utilization of noninvasive vagal nerve stimulator results in significant side effects, particularly depression, in adolescent patients.

Intervention

Device:
GammaCore intervention
Use of the vagal nerve stimulator, GammaCore, on the right side of the neck for two 2 minute stimulations performed 3 times a day
Other:
STEPS management protocol
STEPS is the acronym for the standard management program for our patients with POTS. It includes liberal use of salt, taking in 90-100 ounces of fluid, gradually increasing the duration of aerobic exercise, possible use of one of two prescription medications (metoprolol, and midodrine), and encouragement to set priority and goals

Primary The change in COMPASS-31 scores between individuals in both arms of the study Evaluation of the COMPASS-31 score changes from the start to the finish in individuals in both arms of the study 2 months
Primary The change in Child Functional Disability Inventory scores between individuals in both arms of the study Evaluation of the change in Child Functional Disability Inventory scores between individuals in both arms of the study 2 months
Primary The change in heart rate increase in head up tilt table tests in individuals in both arms of the study Evaluation of the difference in heart rate increase from initial Head up tilt table test (HUTT) from start of study to end of study in individuals in both arms of the study 2 month interval
Secondary Does nVNS influence headache frequency in adolescent patients with POTS Evaluation of patient logs for headache frequency in individual patients in both arms of the study 2 months
Secondary Does nVNS influence ability to increase exercise duration in adolescent patients with POTS Evaluation of patient logs for duration of average weekly exercise 2 months
Secondary Does use of nVNS influence degree of depression in adolescent patients with POTS Evaluation of PHQ-9 surveys from start to finish of study between the two groups 2 months
