New Research Strengthens Link Between Vitamin E and Vaping

In October 2019, the research team reported the first evidence that even short-term vaping causes concerning inflammation in the lungs in the medical journal Cancer Prevention Research

New research has strengthened prior findings on the link between vitamin E acetate and EVALI (E-cigarette or vaping product use-associated lung injury).

For the study, published in the New England Journal of Medicine, the US Centers for Disease Control and Prevention (CDC) analysed bronchoalveolar lavage (BAL) fluid from 51 EVALI patients from 16 states and compared it to BAL fluid from 99 healthy individuals.

Vitamin E acetate, also found in product samples tested by the Food and Drug Administration (FDA) and state laboratories, was identified in BAL fluid from 48 of 51 EVALI patients but was not found in any BAL fluid from healthy people.

In both groups, no other toxicants except coconut oil and limonene were found in BAL fluid.

“These findings support the conclusion that vitamin E acetate is a potential causative agent of EVALI, and that is an important discovery as decisions are made about how to best regulate the rapidly evolving e-cig industry,” said researcher Peter Shields from Ohio State University in the US.

According to the researchers, BAL samples were collected by the CDC from public health laboratories and health departments across the US.

These samples were received from hospital clinical teams that had collected the samples to guide clinical management decisions.

According to the study, the research team provided BAL fluid samples from 99 healthy comparison subjects collected between 2015 and 2019 as part of a tobacco product study unrelated to the ongoing CDC investigation of EVALI.

Here’s how Vaping Can Increase the Risk of Asthma and COPD

Vaping increases risk of asthma and COPD says a study

Inhaling heated tobacco vapor through e-cigarettes increases chances of asthma and chronic obstructive pulmonary disease (COPD), conditions long shown to be caused by smoking traditional, combustible cigarettes.

The research data, published in the American Journal of Preventive Medicine, also suggest chances of developing COPD may be around six times greater among people who vape as well as smoke tobacco regularly, compared with those who don’t use any tobacco products.

“Although e-cigarettes may turn out to be safer than traditional combustible cigarettes, our studies add to growing evidence that they carry health risks,” said researcher Michael Blaha from Johns Hopkins University in the US.

Cases of asthma and COPD are rising worldwide, according to the World Health Organisation (WHO), with most cases of COPD resulting from traditional cigarettes.

To shed light on the risk, the researchers used national survey data gathered by the Behavioural Risk Factor Surveillance System in 2016-17.

In the analysis, published in BMC Pulmonary Medicine, the investigators analysed data from 402,822 people who identified themselves as never smokers — those who smoked less than 100 combustible cigarettes in their lifetimes.

Of these, 3,103 reported using e-cigarettes or vaping, and 34,074 people reported having asthma. Almost 11 per cent of e-cigarette users reported asthma compared with eight per cent of those who had never used e-cigarettes.

The people who reported to be e-cigarette users were 39 per cent more likely to self-report asthma compared with those who said they never used e-cigarettes.

Those who said they used e-cigarettes some days were 31 per cent more likely, and daily users 73 per cent more likely to report asthma, compared with non-e-cigarette users.

For the study published in the American Journal of Preventive Medicine, the researchers analysed the same data from all the questioned participants.

Of the 700,000 plus participants, 61 per cent reported being never smokers, nine per cent current smokers, 30 per cent former smokers, more than three per cent e-cigarette users and two per cent used both e-cigarette and traditional cigarettes.

Of the e-cigarette users, about 11 per cent said they had chronic bronchitis, emphysema or COPD, compared with 5.6 per cent who said they never used e-cigarettes.

Among never smokers, e-cigarette users were 75 per cent more likely to report COPD, compared with those who had never used them.

For both studies, the researchers cautioned that they weren’t designed to show that vaping directly causes lung disease, but only whether doing so was associated with an increased likelihood of having disease. (IANS)
