Key Takeaways

  • Similar levels of biomarkers of inflammation and oxidative stress are seen for dual use of electronic cigarettes and cigarettes and exclusive cigarette use.
  • The researchers found similar inflammatory and oxidative stress profiles for nonuse and exclusive e-cigarette use in the multivariable models.
  • Exclusive e-cigarette use had significantly lower levels of almost all inflammatory and oxidative stress biomarkers other than high-sensitivity C-reactive protein, compared with exclusive smoking.

HealthDay News–Similar levels of biomarkers of inflammation and oxidative stress are seen for dual use of electronic cigarettes and cigarettes and exclusive cigarette use, according to a study published in Circulation.

Andrew C. Stokes, Ph.D., from the American Heart Association Tobacco Regulation and Addiction Center in Dallas, and colleagues examined the correlation of cigarette and e-cigarette use behaviors with biomarkers of inflammation and oxidative stress among adults aged 18 years and older from the Population Assessment of Tobacco and Health Study. Participants were classified based on cigarette/e-cigarette use in the previous 30 days: nonuse, exclusive e-cigarette use, exclusive cigarette use, and dual use.

Of 7130 participants, 58.6%, 1.9%, 29.6%, and 9.9% reported nonuse, exclusive e-cigarette use, exclusive cigarette use, and dual use, respectively. The researchers found similar inflammatory and oxidative stress profiles for nonuse and exclusive e-cigarette use in the multivariable models. Compared with nonuse, exclusive smoking and dual use had higher levels across all biomarkers. Exclusive e-cigarette use had significantly lower levels of almost all inflammatory and oxidative stress biomarkers other than high-sensitivity C-reactive protein, compared with exclusive smoking. Comparable levels of all 5 inflammatory and oxidative biomarkers were seen for dual use and exclusive smoking.

“The results could be used to counsel patients about the potential risk of using both cigarettes and e-cigarettes,” Stokes said in a statement.
