Comparison of the effects of active and passive smoking of tobacco cigarettes, electronic nicotine delivery systems and tobacco heating products on the expression and secretion of oxidative stress and inflammatory response markers. A systematic review
Abstract
Abstract Objectives This work attempts to summarize current knowledge on the effects of active and passive smoking of cigarettes, electronic nicotine delivery systems and tobacco heating products on the expression and secretion of oxidative stress and inflammatory response mediators, and on their possible impact on chronic obstructive pulmonary disease development. Materials and Methods The literature was searched by the terms: ’smoking’, ’active smoking’, ’passive smoking’, ‘main-stream smoke’, ‘side-stream smoke’, ‘secondhand smoke’, ‘cigarette’ ‘THP’, ‘tobacco heating product’, ‘ENDS’, ‘electronic nicotine delivery system’, ‘e-cigarette’, ‘electronic cigarette’, oxidative stress’, inflammatory response’ and ‘gene expression’. Results Cigarette smoking (active and passive) induces oxidative stress and inflammatory response in the airways. We present the effect of active smoking of e-cigarettes (EC) and heat-not-burn (HnB) products on the increased expression and secretion of oxidative stress and inflammatory response markers. However, there is only a limited number of studies on the effect of their second-hand smoking, and those available mainly describe aerosol composition. Discussion The literature provides data which confirm that active and passive cigarette smoking induces oxidative stress and inflammatory response in the airways and is a key risk factor of COPD development. Currently, there is a limited number of data about ENDS and THP active and passive smoking…
