In the United States, researchers at the University of North Carolina have been studying the effects of the electronic cigarette on our lungs. According to the results, this one would trigger a too important immune response that could lead to certain respiratory diseases.
In a study published on theAmerican Journal of Respiratory and Critical Care. Researchers at the University of North Carolina in the United States wanted to explore the potential harmful effects of electronic cigarettes, particularly on the respiratory tract.
Scientists analyzed and compared sputum specimens (bronchopulmonary secretion) from 15 e-cigarette users, 14 cigarette smokers and 15 non-smokers. They found that e-cigarette users displayed significant increases in protein that played a role in pathogen elimination. Although this seems like a good thing on paper, an uncontrolled overproduction of these proteins can contribute to the development of inflammatory lung diseases, such as COPD (Chronic Obstructive Pulmonary Disease) or cystic fibrosis.
It remains important to point out that 15 5 users of e-cigarettes have occasionally said they smoke cigarettes and 12 identified themselves as having smoked cigarettes in the past.
In conclusion, the researchers state: " Our results indicate that the use of the e-cigarette alters the profile of innate defense proteins in airway secretions, inducing both similar and unique changes as compared to smoking. These data challenge the concept that e-cigarettes are a healthier alternative to cigarettes".
