Resolution of recurrent tonsillitis in a non-smoker who became a vaper. A case study and new hypothesis

Abstract

Background Evidence concerning the impact of vaping on respiratory infections remains contradictory. Cell and animal studies suggested that vaping may increase vulnerability to respiratory infections, but human data do not confirm this concern. Case presentation We present a case of a never-smoker who became a vaper and after a few months of e-cigarette use experienced a complete resolution of chronic tonsillitis and a marked improvement in tonsilloliths. Conclusions As this is a never-smoker, the improvements cannot be attributed to smoking cessation. One possible explanation is that the improvement was due to antimicrobial properties of propylene glycol. The hypothesis could be tested by a trial of zero-nicotine e-cigarettes in patients with recurrent bacterial throat infection.
