Abstract
Background: Tobacco consumption is one of the leading causes of oral submucous fibrosis, oral cancer and even premature death. The present study was designed to compare the biochemical parameters and nonenzymatic antioxidant status and the lipid peroxidation products in pan masala tobacco users as compared with age-matched non-user controls.
Methods: Pan masala and tobacco users of age 33.2±9.94 years and age-matched controls (31.2±4.73 years) were enrolled for the study. Plasma levels of vitamin E, vitamin C, albumin, bilirubin, uric acid, glucose, urea, creatinine, aspartate amino transferase (AST), alanine amino transferase (ALT) were measured by standard methods. Serum malondialdehyde (MDA) levels were estimated as a measure of lipid peroxidation.
Results: In the pan masala tobacco users, as compared to the controls, the level of vitamin C(68.5±5.9 vs 97.9±9.03 μmol/L, p≤0.05) vitamin E (18.4±5.3 vs 97.9±9.03 μmol/L, p≤0.001), albumin (37.5±7.01vs 44.3±9.99 g/L, p≤0.001), and malondialdehyde (10.8±1.29 vs 1.72±1.15 nmol/ml, p≤0.001 ) were found to be significantly altered. Malondialdehyde was significantly correlated with vitamin E (r=1.00, p<0.001) and vitamin C (r =1.00, p<0.001) in pan masala tobacco users. Serum levels of AST (31.0±16.77 IU) and ALT (36.7±31.3 IU) in the pan masala tobacco users were significantly raised as compared to the controls (AST, 25.2±9.51 IU, p=0.038;ALT, 26.2±17.9 IU, p=0.038).
Conclusion: These findings suggest that pan masala tobacco users are in a state of oxidative stress promoting cellular damage. Non-enzymatic antioxidants are depleted in pan masala tobacco users with subsequent alteration in the biochemical parameters. Supplementation of antioxidants may prevent oxidative damage in pan masala tobacco users.
