COVID19 pandemic has stormed the world like no other storm/cyclone and some patients with COVID-19 just crash suddenly. These patients often present with a Multiple-Organ-Failure along with hypercytokinaemia, a result of the Cytokine Storm.
A Cytokine Storm is an excessive release of proinflammatory cytokines in response to an infection. Recent studies have shown that in patients with SARS-CoV-2 infection, a strong correlation is seen between the severity of the disease and levels of proinflammatory cytokines .
Interferons, Interleukins, Chemokines, Colony-stimulating factors and Tumor Necrosis factor are the key cytokine types involved in the cytokine storm.
