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). Here, CXCL8 is linked to bacterial urinary tract infection.
