Augmented levels of IL-2, IL-6, IL-7, IL-10, granulocyte-colony stimulating factor (G-CSF), TNF-α, IFN-γ-inducible protein 10 (IP10), macrophage inflammatory protein 1-α (MIP1A), and monocyte chemoattractant protein (MCP1) were associated with COVID-19 severity; a cytokine outline favoring secondary hemophagocytic lymphohistiocytosis (sHLH) [80, 81].
