Title : Severe SARS-CoV-2 & Cancer: Unlocking the immunology with promising therapeutic interventions
Abstract:
Coronavirus disease 2019 (COVID-19), a respiratory illness caused by betacoronavirus SARS-CoV-2, has broad clinical presentations ranging from asymptomatic to fatal outcomes. Due to their immunocompromised status, cancer patients are at an increased risk for severe SARS-CoV-2 infection. Given the diverse clinical presentations, we developed a model to explain the pathogenesis of severe SARS-CoV-2 and its immunological interplay with cancer. Since SARS-CoV-2 causes multi-organ dysfunction through IL-6-mediated inflammation and hypoxia, while malignancy causes apoptosis through hypoxia-induced cellular metabolic alterations, we propose a mechanism by which both conditions resulted in IL-6 upregulation causing increased cytokine release and systemic injury with clinical trial support.
Due to the limited therapeutic interventions for severe COVID-19 especially in the immunocompromised such as cancer patients, we propose the use of a stem cell therapy that has yielded promising efficacy in COVID-19 patients with severe disease. This therapy, mesenchymal stem cells, possesses regenerative, antiviral and immunomodulatory properties that can inhibit viral replication, while dampening the cytokine response with resulting systemic inflammation and injury. Clinically, it has demonstrated a 91% overall survival and 100% survival in patients younger than 85 years old within a month after treatment with results holding steady for 6 months. Thus, cancer patients can quickly contain SARS-CoV-2 with limited interruptions to their treatment schedule.
Audience Take Away:
