Vagus Nerve Stimulation for Neuropathy

This trial explores a new, non-invasive treatment called Transcutaneous Auricular Vagus Nerve Stimulation (AVNS), which stimulates the ear to understand nerve pain in people living with HIV. The research aims to assess how this treatment affects heart function and pain signals, potentially leading to improved future treatments for nerve pain. Participants will either receive the ear stimulation treatment or be placed on a waitlist. The trial seeks individuals with HIV who have experienced nerve pain in a glove-like or stocking-like pattern for at least three months and have stable medical care. As an unphased trial, this study offers a unique opportunity to contribute to groundbreaking research that could enhance future treatments for nerve pain.

Research has shown that transcutaneous auricular vagus nerve stimulation (taVNS) is generally safe and well-tolerated by patients. Studies have found that this non-invasive treatment carries minimal risk. For instance, one trial reported that patients using taVNS at home experienced only a few minor side effects. Another study confirmed that taVNS was easy to use and well-tolerated, with no major negative effects. This evidence suggests that taVNS is a promising and safe option for managing nerve-related conditions.¹²³⁴⁵

Unlike the standard treatments for neuropathy, which often include medications like pain relievers, antidepressants, or anticonvulsants, transcutaneous auricular vagus nerve stimulation (AVNS) offers a non-invasive alternative by stimulating the vagus nerve through the ear. This method doesn't rely on drugs, which means it could potentially avoid the side effects commonly associated with medication. Researchers are excited about AVNS because it targets the nervous system directly, offering a novel approach that might bring relief faster and more effectively for some patients. Plus, the ease of administering AVNS could make it more accessible for a broader range of patients.

Research has shown that transcutaneous auricular vagus nerve stimulation (AVNS) can relieve pain and improve other symptoms. One study found that AVNS significantly reduced pain and tiredness in patients with systemic lupus erythematosus (SLE), an autoimmune disease. The vagus nerve controls body functions like heart rate and digestion, and stimulating it can alter the body's pain response. Additionally, vagus nerve stimulation (VNS) has treated conditions like epilepsy and depression, suggesting it may help with nerve-related issues. In this trial, participants in the Auricular Vagus Nerve (AVNS) Group will receive AVNS sessions, while those in the Waitlist Control group will not receive an intervention during the study period. These findings suggest that AVNS might also be effective for nerve pain in people living with HIV.⁶⁷⁸⁹¹⁰
