In the present case, serum levels of Th1 cytokines (IFN-γ) were significantly reduced, while the levels of Th2 cytokines (IL-4, IL-5, and IL-6) and the Treg cytokine (IL-10 and TGF-β) were significantly increased; after two courses of the VRD treatment, IFN-γ levels increased, while those of IL-4, IL-5, IL-6, IL-10, and TGF-β decreased with improvements in LV and eosinophilia. This evidence concerns the gene IL10 and Increased total eosinophil count.
