Effects of smokeless dipping tobacco (Naswar) consumption on antioxidant enzymes and lipid profile in its users
Journal Title: Pakistan Journal of Pharmaceutical Sciences - Year 2015, Vol 28, Issue 5
Abstract
Dipping tobacco, traditionally referred to as moist snuff, is a type of finely ground, moistened smokeless tobacco product. Naswar is stuffed in the floor of the mouth under the lower lip, or inside the cheek, for extended periods of time. Tobacco use causes dyslipidemia and also induces oxidative stress, leading to alteration in levels of antioxidant enzymes. Dyslipidemia and oxidative stress in turn play a vital role in the development of cardiovascular disease (CVD). Studies conducted on smokeless tobacco products reveal contradictory findings regarding its effects on lipid profile and antioxidant enzymes. As use of Naswar is quite common in Pakistan, the current study aimed to evaluate levels of the antioxidant enzymes viz glutathione per oxidase (GPx) and super oxide dismutase (SOD), alongside lipid profile parameters such as total cholesterol, triglycerides, High density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) to assess the risk of adverse cardiovascular events in Naswar users.90Healthy males aged 16-43 years, who consumed Naswar daily, were selected for the study, alongside 68 age-matched non-tobacco users as controls. Both GPx and SOD levels as well as serum HDL-C were significantly reduced (P<0.01) in Naswar users, whereas serum total cholesterol, LDL-C, triglycerides and LDL-C/HDL-C ratio were significantly increased (P<0.01) in Naswar consumers compared to controls. Our findings indicate deleterious effects of Naswar usage on health by causing altered lipid profile and antioxidant enzymes thereby placing its consumers at an increased risk of cardiovascular disease.
