VNS for Long-COVID-19

November 6, 2024 updated by: David Putrino, Icahn School of Medicine at Mount Sinai

Vagus Nerve Simulation for Long-COVID-19

The goal of this proposed clinical case series is to evaluate the effect of a non-invasive vagus nerve stimulation paradigm on: 1) Symptom reporting via validated patient reported outcomes, and 2) objective clinical biomarkers of autonomic nervous system function.

This will be a placebo controlled, randomized controlled trial with a crossover design built in. This study will aim to recruit 40 people with Long COVID to be a part of this research.

Study Overview

Detailed Description

Participants will be randomized into one of two arms. Those in the "active VNS" arm will be sent home with a portable VNS device and asked to perform a daily VNS protocol designed to down regulate sympathetic nervous system activity for six weeks.

Those in the "sham VNS" arm will be asked to use the VNS device daily on a sham setting for six weeks. Those randomized to the sham group will be given the opportunity to "crossover" into the active VNS arm once they have completed the sham arm (Week 12). The participant and assessor will be blinded.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Composite Dysautonomia Symptom Score (COMPASS 31)
Time Frame: Baseline (Week 0)

COMPASS-31 (the composite autonomic symptom) score is a self-rating questionnaire evaluating six domains of autonomic function: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor domains.

The total score will be between 0 to 100, and a higher score indicates more severe autonomic symptoms. It is based on the original Autonomic Symptom Profile (ASP) and COMPASS, is internally consistent and applies a much-simplified scoring algorithm suitable for widespread use in autonomic research and practice.

Neuro Quality of Life Score
Time Frame: Baseline (Week 0)
The NeuroQOL is a self-report of health-related quality of life in 17 domains and sub-domains for adults. Item banks consist of 302 items in total (range from 5 to 45) which are used adaptively to test a variable number and content of items in a computer assisted testing format. All items are rated on a five-option scale based on intensity (e.g. 1 = not at all, 2 = a little bit, 3 = somewhat, 4 = quite a bit, 5 = very much) or frequency ("never" to "always"). Raw scores are converted based on consistent metric (T-distribution) with data from the US general population with a T-score mean of 50 and standard deviation of 10.

Post-Exertional Malaise (PEM) Screener
Time Frame: Baseline (Week 0)
Post-exertional malaise (PEM) is the worsening of symptoms following even minor physical or mental exertion, with symptoms typically worsening 12 to 48 hours after activity and lasting for days or even weeks. The PEM assesses symptom frequency and severity over a 6-month look back period. Frequency is rated on a 5-point Likert scale: 0 = none of the time, 1 = a little of the time, 2 = about half the time, 3 = most of the time, and 4 = all of the time. Severity is also rated on a 5-point Likert scale: 0 = symptom not present, 1 = mild, 2 = moderate, 3 = severe, 4 = very severe. Total score ranges 0-40, with higher scores indicate worse health outcomes.

EQ-5D-5L Quality of Life Score
Time Frame: Baseline (Week 0)
The EQ-5D gives a measure of health-related quality of life. The descriptive system gives a weighted index score from 0-1 where 1 is perfect health and 0 is the worst health possible. The visual analogue score is a measure of overall self-rated health status where 100 is the best imaginable health state and 0 is the worst imaginable health state, thus, higher scores indicate better health outcomes.
