Immune and endocrine alterations were observed in TB patients, characterized by increased cortisol, estradiol, prolactin, growth hormone, thyroid hormone, and dopamine concentrations, which were accompanied by increased interferon (IFN)γ, TNFα, C-reactive protein (CRP), IL-1α, IL-6, and IL-10 concentrations when compared to healthy controls (4, 10–12). This evidence concerns the gene IL6 and tuberculosis.
