E-cigarettes alter the inflammatory state of a number of organs within the physique, which may affect how they reply to infections, based on a report printed Tuesday by researchers at UC San Diego School of Medicine.

Daily use of pod-based e-cigarettes alters irritation in a number of organ techniques together with the mind, coronary heart, lungs and colon, the researchers discovered. Effects additionally differ relying on the e-cigarette taste, and might affect how organs reply to infections, resembling SARS-CoV-2.

The research, printed Tuesday within the journal eLife, is the primary to evaluate JUUL gadgets and their flavorants in a multi-organ vogue.

“These pod-based e-cigarettes have only become popular in the last five or so years, so we don’t know much about their long-term effects on health,” mentioned senior research creator Dr. Laura Crotty Alexander, affiliate professor of drugs at UCSD School of Medicine and part chief of pulmonary important care at Veterans Affairs San Diego Healthcare System.

More than 12 million adults within the United States use e-cigarettes, with the very best charges of use amongst these aged 18-24. Despite their reputation, analysis on e-cigarettes has been largely restricted to research of short-term use, older gadgets resembling vape pens or field mods, and e-liquids with considerably decrease nicotine concentrations than the trendy rechargeable pod-based techniques.

Crotty Alexander’s workforce targeted on the present most outstanding e- cigarette model, JUUL, and its hottest flavors: mint and mango. To mannequin persistent e-cigarette use, younger grownup mice have been uncovered to flavored JUUL aerosols 3 times a day for 3 months. Researchers then seemed for indicators of irritation throughout the physique.

The report’s authors noticed essentially the most putting results within the mind, the place a number of inflammatory markers have been elevated together with a mind area important for motivation and reward-processing. The findings elevate main considerations, the researchers mentioned, as irritation on this area has been linked to anxiousness, despair and addictive behaviors.

“Many JUUL users are adolescents or young adults whose brains are still developing, so it’s pretty terrifying to learn what may be happening in their brains considering how this could affect their mental health and behavior down the line,” Crotty Alexander mentioned.

Inflammation additionally elevated within the colon, notably after one month of e-cigarette publicity, which might improve danger of gastrointestinal illness. In distinction, the center confirmed decreased ranges of inflammatory markers. Authors mentioned this might make cardiac tissue extra weak to an infection.

Researchers additionally discovered that whereas lungs didn’t present tissue-level indicators of irritation, quite a few modifications have been noticed within the samples, calling for additional research on pulmonary well being.

The research additionally discovered that the inflammatory response diverse relying on which JUUL taste was used. For instance, the hearts of mice who inhaled mint aerosols have been rather more delicate to the results of bacterial pneumonia in comparison with those that inhaled mango aerosols.

“This was a real surprise to us,” Crotty Alexander mentioned. “This shows us that the flavor chemicals themselves are also causing pathological changes. If someone who frequently uses menthol-flavored JUUL e-cigarettes was infected with COVID-19, it’s possible their body would respond differently to the infection.”
