“…It is interesting that past or present e-cigarette users were signi cantly less likely than never e-cigarette users to demonstrate an obstructive pattern on spirometry. This is contrary to ndings in the general population reported by other groups who described increased obstruction associated with e-cigarette use even when adjusted for concurrent tobacco cigarette use (20,21). It is possible that the older age of the non-e-cigarette users (22) and their slightly higher daily cigarette intake (and probable higher total lifetime exposure to cigarettes) could have contributed to their higher rate of obstruction.…”

Objectives. To describe electronic cigarette (e-cigarette) usage behaviors, beliefs, and spirometry patterns in people with HIV (PWH) who smoke tobacco cigarettes.Design: Cross-sectional, observational, pilot study conducted in an HIV care center in the Bronx, New York.Methods Enrolled PWH who confirmed tobacco cigarette usage completed an audio computer-assisted self-interview and spirometry. Because a minority of PWH tobacco users have ever used e-cigarettes, we purposely oversampled current and past e-cigarette users.Results We enrolled 42 participants into the study. Of these, 19 were current e-cigarette users, 13 were past users, and 10 were never users. Current and past e-cigarette users were significantly younger than never users, and they were more likely to have ever used other tobacco products (mostly pipes and cigars). There were no significant differences in tobacco smoking frequency, daily cigarette consumption, nicotine dependence, or motivation to quit between e-cigarette users and non-users. Current and past users were less likely to demonstrate an obstructive pattern on spirometry than never users. Current e-cigarette users cited assistance in attempting to quit tobacco cigarettes as the most common reason for their use. Our sample used eight different vaping devices and most commonly used tobacco/nicotine as their vaping substrate.Conclusions PWH tobacco cigarette smokers who use e-cigarettes most commonly vape tobacco/nicotine products. Current e-cigarette users did not smoke fewer tobacco cigarettes per day than non-users. The observation that those who had never used e-cigarettes were more likely to demonstrate obstruction on spirometry was surprising and may merit further investigation.

“…Alternative forms of nicotine intake have similar harmful effects of altering airflow through the airways as smoking cigarettes and, therefore, may not be a healthier alternative to smoking [30]. Other authors recognized that using an e-cigarette for 5 min causes an increase in peripheral airway resistance, increased impedance, and oxidative stress and considered it an important clinical effect [31].…”

Background The effects of cigarette smoking on the health of active smokers and passive smokers have long been known, in contrast to the effects of alternative forms of nicotine intake that are gaining popularity. The aim of the study was to assess the effects of smoking traditional cigarettes and alternative forms of nicotine intake on the functional state of the respiratory system of smokers and non-smokers. Material/Methods Study participants (n=60) were divided into 3 groups: non-smokers (control group), cigarette smokers, and nicotine alternative users. Respiratory function testing (spirometry), forced oscillation technique, and measurement of respiratory muscle strength (PImax, PEmax) were performed. All of the above respiratory function tests were performed in accordance with European Respiratory Society and American Thoracic Society recommendations. Results Smokers and those using alternative forms of nicotine intake had significantly higher values, including resistance at 5 Hz% and 11 Hz%, among others. Conclusions Smokers and users of alternative forms of nicotine are characterized by reduced flow through the small bronchioles, as evidenced by a reduction in maximal expiratory flow at 25% of vital capacity. Smokers and users of alternative forms of nicotine have higher resistance values at the height of small and medium bronchioles. Assessment method of technical forced oscillation parameters is simple to perform to detect early airway changes and is an important element in the early diagnosis of changes in smokers. The correlation analysis showed a significant correlation between age of smoking initiation/use of alternative forms of nicotine and changes in mid bronchial resistance.

Background With the use of heated tobacco products (HTPs) becoming more widespread in Japan, interested in the health effects of HTP use have grown. Since the vast majority of HTP users are former smokers, information about the user's smoking history and health status before HTP use is needed when assessing the health effects of HTP use. The limited epidemiological studies available did not consistently considered this information. Methods We conducted a cross-sectional study investigating the relationship between HTP use and respiratory chronic diseases and symptoms. A large-scale research panel in Japan managed by Cross Marketing Inc. was randomly sent questionnaires via the Internet, and individuals who met the study criteria and were either current exclusive HTP users, current exclusive cigarette users or those had never used tobacco products were selected. And obtained information about the participants' smoking history and health status before they used HTPs. The effects of participant smoking history prior to HTP use and the impacts on outcomes upon switching to HTP were assessed using a logistic regression model. And the odds ratio (OR) for current exclusive HTP users relative to never tobacco users was calculated. The OR was calculated under two scenarios, either ignoring or taking into account smoking history. Results Of the participants from whom responses to the questionnaires were obtained, 17,406 participants were included in the analysis. Almost all participating current exclusive HTP users had a history of long-term smoking (mean: 28.6 years), and the occurrence of outcomes both before and after the start of HTP use were reported. The ORs, without adjustment and with adjustment for smoking history prior to HTP use were, in the case of COPD, 3.23 (95% CI: 1.37–7.61) and 1.85 (95% CI: 0.70–4.89) respectively. These results suggest that smoking history prior to HTP using affects the occurrence of outcomes. Conclusions These results underscore the importance of considering smoking history when assessing the health effect of HTP use. Since the duration of HTP use is considerably shorter than that of cigarette use at present, further research, such as follow-up surveys assessing the long-term health effects of HTP use, will be necessary.
