Scientists from the UNC Lineberger Comprehensive Cancer Center (USA) found that using e-cigarettes can lead to dysbiosis in the nasal cavity and increase the risk of developing respiratory diseases. Research results It was published In the journal Nicotine and Tobacco Research (NTR).
The researchers collected nasal epithelial fluid samples from 20 nonsmokers, 28 volunteers who used e-cigarettes, and 19 people who used e-cigarettes. They then used genetic sequencing to determine the type and number of bacteria present in the nasal microbiome.
The results showed that the nasal microbiome of the two-smoker group was more likely to have an excess of harmful bacteria, such as Staphylococcus aureus, which can cause life-threatening infections and also contribute to the development of chronic obstructive pulmonary disease and asthma.
Only one beneficial bacteria called Lactobacillus iners was found more frequently in smokers compared to non-smokers. It can protect the body from respiratory diseases.
Scientists have concluded that smoking can trigger immune dysfunction in the nasal mucosa. Moreover, the negative impact manifests itself differently depending on gender and the amount of nicotine metabolites in the body.
Earlier scientists named The three best strategies for quitting smoking.
