How do e-cigarettes affect susceptibility to pneumococcal bacteria?

Many people try to quit smoking, for example by using nicotine patches or switching to e-cigarettes. Of course, e-cigarettes are not really healthy for the body either. Researchers have now found that vaping with e-cigarettes may increase the risk of developing pneumonia.

The researchers at the Queen Mary University of London found that e-cigarettes can increase the risk of pneumonia. The doctors published the results of their study in the journal "European Respiratory Journal".

The risk of pneumonia is increased

There are already several studies that compare the advantages and disadvantages of e-cigarettes with smoking normal cigarettes. In the current study, no direct comparison was made between the effects of e-cigarettes and the smoking of normal cigarette tobacco. In the current study, scientists focused solely on the effects of e-cigarettes and found that users of electronic cigarettes were at higher risk of pneumonia compared to people who did not use e-cigarettes.

Increased susceptibility to pneumococcal bacteria has been noted

The so-called evaporation appears to lead to an increased susceptibility to pneumococcal bacteria, explains study author Professor Jonathan Grigg from the Blizard Institute at the Queen Mary University of London. These bacteria can cause serious infections, among other things, they can also cause pneumonia.

Study included three different studies

In their research, the scientists carried out three different types of experiments. In one experiment, mice inhaled the steam and were then exposed to pneumococcal bacteria. The nasal mucosa of eleven users of e-cigarettes was also examined. The results were then compared to those of subjects who did not use e-cigarettes. In a third experiment, human cells from the nose were exposed to the vapor of e-cigarettes in the laboratory.

The amount of harmful bacteria increased due to the vapor of e-cigarettes

The research team noticed a sharp increase in the amount of bacteria that adhered to the airway cells after they were exposed to the vapor of e-cigarettes. Earlier studies have found that such adhesion increases susceptibility to the disease. “Some people may vaporize because they think e-cigarettes are completely safe or to quit smoking. However, the results of the study show that inhaling steam from e-cigarettes can also have adverse health effects, ”explains expert Professor Grigg in a press release from the Queen Mary University of London.

Nicotine gum and plasters do not endanger the respiratory tract

Many people use e-cigarettes to quit smoking. In contrast to e-cigarettes, other aids for weaning cigarettes, such as nicotine patches or nicotine chewing gum, do not lead to an increased concentration of potential pathogens in the respiratory tract, say the doctors.

Are E-Cigarettes a Safe Alternative to Smoking?

Scientists already said last October that a large-scale switch from tobacco to e-cigarettes could prevent millions of premature deaths by 2100, even if the devices are not harmless to health. The vapor of e-cigarettes contains no tar and less toxins than the smoke of normal cigarettes, the reasoning.

E-cigarettes are often rated as a safe alternative to smoking, but the question remains whether e-cigarettes are tempting to smoke or help weaning. Younger people in particular could become lifelong addicted to nicotine due to the alleged harmless e-cigarettes. (as)
