Insights

Cytokine storm in COVID-19 patients was investigated. Serum levels of IL-17A, IL-23, and CCL3 did not significantly differ between patients and controls, suggesting they may not drive inflammation in this group.

Area of Science:

  • Immunology
  • Virology
  • Critical Care Medicine

Background:

  • Cytokine storm is a severe complication of COVID-19.
  • Interleukin-17A (IL-17A), IL-23, and Chemokine (C-C motif) ligand 3 (CCL3) roles in COVID-19 cytokine storm require clarification.

Purpose of the Study:

  • To investigate serum levels of IL-17A, IL-23, and CCL3 in hospitalized COVID-19 patients.
  • To compare these levels with healthy controls and analyze influencing factors like gender, age, and comorbidities.

Main Methods:

  • Prospective study involving 30 hospitalized COVID-19 patients and 30 healthy controls.
  • Serum cytokine levels (IL-17A, IL-23, CCL3) measured using Enzyme-Linked Immunosorbent Assay (ELISA).

Main Results:

  • No significant difference in serum IL-17A, IL-23, or CCL3 levels between COVID-19 patients and healthy controls.
  • Male COVID-19 patients exhibited higher serum IL-23 levels compared to female patients.
  • Age, hypertension, type 2 diabetes, and lung involvement did not affect the measured cytokine levels.

Conclusions:

  • IL-17A, IL-23, and CCL3 do not appear to be major drivers of pro-inflammatory responses in Iranian hospitalized COVID-19 patients.
  • Gender may influence IL-23 production in COVID-19, warranting further investigation.
