All cytokines, i.e., EGF, IFN-γ, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-8, IL-9, IL-10, IL-13, IL-17A, IL-33, IP-10, IFN-γ, MIP-1β, TNF-α, and VEGF except MCP-1 were significantly higher in the KD group, compared with the FC group, whereas the expression of IFN-γ, IL-1β, IL-6, IL-8, IL-17A, IL-33, MCP-1, MIP-1β, and TNF-α were significantly lower in the urine of KD patients, as compared with the UTI group, as tested by the Kruskal–Wallis test (Table 2). The gene discussed is CCL2; the disease is bacterial urinary tract infection.
