The Effect of Tuberculosis on Serum Receptor Activator of Nuclear Factor-k B Ligand, Osteoprotegerin, and Total Antioxidant Capacity

The aim of the present study was to evaluate the osteoprotegerin (OPG), receptor activator of nuclear factor-kappa B ligand (RANKL), oxidant, and antioxidant status in untreated active pulmonary tuberculosis patients (PTB). Serum was obtained from 42 patients with different forms of untreated active PTB and 41 healthy subjects, as the control group. The serum levels of OPG, RANKL, tumor necrosis factor alpha (TNFα), malondialdehyde (MDA), total antioxidant capacity (TAC), and the lipid profiles were determined using standard methods. Patients with PTB were detected to have significantly higher plasma MDA, TNFα, OPG, and RANKL levels, and lower TAC levels, when compared to the healthy controls(p
