Elements of Th1/Th2 response and disease severity in COVID-19 patients: A short report

Abstract

The presence of a complex immune dysregulation syndrome has been established in COVID-19 patients. We aimed to assess Th1/Th2 response in COVID-19 patients and its association with disease severity by performing a prospective cohort study in a tertiary hospital COVID-19 referral center. We report no difference between Th1/Th2 responses between patients with severe and mild disease, except for levels of interleukin-6 (IL-6) and IL-10. Future larger studies should examine lung-specific versus systemic inflammatory responses, as well as, diverse immunotypes driving poor clinical outcomes.
