The evidence showed hyperglycemia to be associated with unfavorable treatment outcomes; altered counts and functioning of dendritic cells, monocytes, and CD4+ T cells; and changes in cytokine levels (mainly INF-γ, IL-17, IL-1β, IL-2, IL-6, IL-10, and TNF-α) in patients with DM-TB. Here, TNF is linked to Hyperglycemia.
