| 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 (TNFa), 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, TNFa, OPG, and RANKL levels, and lower TAC
levels, when compared to the healthy controls(p\0.05 in
all of the cases). Low TAC and high MDA levels in PTB
patients are indicators of oxidative stress in these patients.
Severe oxidative stress and increased RANKL and OPG
may induce vascular calcification in PTB patients. |
