- Brief Summary
COVID-19 is a disease caused by the virus, SARS-CoV-2. Patients with this viral infection are at risk for developing pneumonia and acute respiratory distress syndrome (ARDS). Approximately 20% to 30% of hospitalized patients with COVID-19 and pneumonia require intensive care for respiratory support. Clinically, ARDS presents with severe hypoxemia evolving over several days to a week in combination with bilateral pulmonary infiltrates on chest X-ray. Widespread alveolar epithelial cell and pulmonary capillary endothelial injury can lead to severe impairment in gas exchange. In one report of 1,099 patients hospitalized with COVID-19, ARDS occurred in 15.6% of patients with severe pneumonia. In a smaller case series of 138 hospitalized patients, ARDS occurred in 19.6% of patients and in 61.1% of patients admitted to an intensive care unit (ICU).
To date, no effective treatment has been established to treat COVID-19 or to prevent progression of ARDS. It is thought that a heightened immune response with an unbalanced release of inflammatory mediators in the airway is a major cause of morbidity and mortality associated with the disease. It is therefore reasonable to postulate that improved outcomes may be obtained in patients with a balanced immune response with adequate viral control and appropriate counter-regulatory immune responses whereas a poor outcome may be expected in patients with inadequate viral control or a heightened immune response or what is referred to as a "cytokine storm". Thus, modulating the pulmonary immune response without suppressing the immune system would be a viable strategy for patients with COVID-19. The current literature supports the role of neuromodulation, particularly vagal nerve stimulation (VNS), in modulating the immune response. Modulating the pro-inflammatory pathway through VNS has been demonstrated to decrease inflammatory mediators and improve outcomes in several animal models and in humans.
Percutaneous electrical nerve field stimulation (PENFS) provides a novel, non-invasive method of VNS through a non-implantable device applied to the external ear. Already, the FDA has cleared this technology for reducing symptoms of opioid withdrawal in patients with opioid use disorder. Symptoms of opioid withdrawal can be decreased by approximately 90% after 1 hour of stimulation. Similarly, the IB-Stim device has been shown to improve symptom in children with abdominal-pain-related functional GI disorders and recently received market approval by the FDA for that indication. Unpublished studies have demonstrated marked decrease in inflammation with PENFS compared to sham stimulation in a model of TNBS colitis. While the efficacy of PENFS in modulating the progression of pulmonary disease in patients with COVID-19 is unknown, several proposed mechanisms for regulation of the immune response through VNS have already been demonstrated. We propose to perform an open label, randomized study to evaluate the efficacy of PENFS for the treatment of respiratory symptoms in patients with COVID-19.
