Introduction: Tuberculosis (TB) remains a significant public health problem, with an estimated one-third of the world's population being infected. Cytokines play a major role in protection against Mycobacterium tuberculosis (M. tuberculosis) infection and regulate the immune responses at a cellular level. Most studies on cytokines during TB are from "in vitro"-stimulated lymphoid cells with few reports on in vivo plasma levels. The aim of this study was to evaluate the levels of tumor necrosis factor-α (TNF-α) in new, undertreatment (UT), and multidrug-resistant (MDR) pulmonary and extrapulmonary cases. Materials and Methods: The study was conducted in the Department of Microbiology, Jawaharlal Nehru Medical College (J.N.M.C.), Aligarh Muslim University (A.M.U.), Aligarh, Uttar Pradesh, India. Results: The levels of TNF-α were measured in 76 serum samples from TB patients by an enzyme linked immunosorbent assay (ELISA) kit (Diaclone Sas, 1 BD, A Flemming Besancon Cedax, France), along with 10 healthy controls. Complete clinical, radiological and treatment data were collected. The TNF-α levels were elevated in new cases (P < 0.05) and MDR cases (P < 0.05) but not significantly for UT cases (P > 0.05). Conclusions: An understanding of this response may lead to an insight into the pathogenesis and novel therapies for TB.
