Additional analyses of blood samples of children with ARDS treated with methylprednisolone showed a decrease in levels of IFN-α, IL-6, IL-10, monocyte chemoattractant protein (MCP)-1, granulocyte colony-stimulating factor (G-CSF), and granulocyte macrophage colony-stimulating factor (GM-CSF) and increased IL-17α by day 7 and increased total leukocyte and platelets counts by day 7 [108]. This evidence concerns the gene CSF2 and acute respiratory distress syndrome.
