However, a 2014 cross-sectional study conducted in India reported that individuals with LTBI and T2DM had decreased mean of Mtb antigen-stimulated (net cytokines) levels including lower IFN-γ (10.5 pg/mL vs. 249.2 pg/mL), TNF-α (6.5 pg/mL vs. 328.1 pg/mL), interleukin (IL)-17A (14.2 pg/mL vs. 24.4 pg/mL), and IL-10 (95.6 pg/mL vs. 220.6 pg/mL) when compared to LTBI individuals without T2DM [21]. This evidence concerns the gene IL17A and type 2 diabetes mellitus.
