Oxidative Stress Markers in Tuberculosis and HIV/TB Co-Infection
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 8
Abstract
Introduction: Dysfunction of redox homeostasis has been implicated in many pathological conditions. An imbalance of pro- and anti-oxidants have been observed in Tuberculosis (TB) and its co-morbidities especially HIV/AIDS. The pro inflammatory milieu in either condition aggravates the physiological balance of the redox mechanisms. The present study therefore focuses on assessing the redox status of patients suffering from TB and HIV-TB co-infection. Aim: To assess the oxidative stress markers in the HIV-TB and TB study cohort. Materials and Methods: The current prospective study was conducted in Haffkine Institute, Parel, Maharashtra, India, during January 2013 to December 2015. Blood samples from 50 patients each suffering from active TB and HIV-TB co-infection were collected from Seth G.S.Medical College and KEM Hospital Mumbai and Group of Tuberculosis Hospital, Sewree Mumbai. Samples were processed and the experiments were carried out at the Department of Biochemistry, Haffkine Institute. Samples from 50 healthy volunteers were used as controls. Serum was assessed for pro-oxidant markers such as Nitric Oxide (NO), Thiobarbituric Acid Reactive Species (TBARS), C-Reactive Protein (CRP), superoxide anion. Antioxidant markers such as catalase and Superoxide Dismutase (SOD) were assessed. Total serum protein, was also assessed. Results: Among the pro-oxidants, serum NO levels were decreased in TB group while no change was seen in HIV-TB group. TBARS and CRP levels showed significant increase in both groups; superoxide anion increased significantly in HIVTB group. Catalase levels showed decreased activities in TB group. SOD activity significantly increased in HIV-TB but not in TB group. The total serum proteins were significantly increased in HIV-TB and TB groups. The values of Control cohort were with the normal reference ranges. Conclusion: In the present study, we found the presence of oxidative stress to be profound in the TB and HIV-TB coinfection population.
