can vaping cause pulmonary fibrosis

Vaping may cause deadly lung diseases, says study. The new study found e-cigarette users had significantly higher levels of proteins in their airways that are linked to chronic obstructive pulmonary disease and cystic fibrosis. And the same proteins have also been linked to cell death in the tissues lining the blood vessels and organs.

Pulmonary fibrosis is a fatal, incurable lung disease in which the lung tissue hardens and ceases to transfer oxygen into the blood. It is assumed to be a kind of autoimmune reaction, triggered by inhaled particles (such as coal dust, metal dust, asbestos but also pesticides and detergents). It is a rare condition, but former smokers frequently exposed to the kinds of particles have an elevated risk of contracting it.

Do fibroblasts die from nicotine?

The researchers then experimented with e-liquids containing different amounts of nicotine, an active component of e-cigarettes. In those studies, fibroblasts exposed to nicotine-free e-liquids underwent cell death while those exposed to nicotine-containing e-liquids showed increased viability, with higher concentrations of nicotine leading to a greater increase in viability. These cells also super-charged their expression of a protein that binds to nicotine, called the alpha 7-nicotinic acetylcholine receptor.

Does vaping help with fibrosis?

They found that when fibroblasts were exposed to e-cigarette aerosol extract, they were significantly more viable than those exposed to smoke extracts, suggesting that vaping— to a greater extent than tobacco smoking—could contribute to fibrosis by helping fibroblasts stay alive for an abnormally long time.

Does nicotine affect fibroblasts?

Because the overactive fibroblasts were found to also increase the expression of a certain nicotinic receptor, Nho said finding a way to inhibit the pathological functions of the receptor that is abnormally regulated by nicotine in e-cigarettes could help to de-activate the fibroblasts and reduce scar formation. Further research can help to test this idea and determine whether different e-cigarette brands or components have different effects on fibroblast activity.

Do fibroblasts die off?

In normal conditions, fibroblasts activate and proliferate when they are needed to heal a wound and then die off when no longer needed. In the case of lung fibrosis, fibroblasts become overactivated and then fail to die off, leading to a damaging buildup of scar tissue.

Does inhibiting nicotinic receptors slow scar formation?

The new study, conducted in cell cultures, also suggests that inhibiting a certain nicotinic receptor could help promote the death of overactive fibroblast cells and thus slow scar formation, called fibrosis, in affected individuals.

Does vaping cause lung damage?

Vaping is known to cause lung tissue injuries. While the study was not designed to uncover the mechanisms behind the serious lung injuries and deaths that have been linked with vaping, the findings shed light on how e-cigarettes may affect the crucial cell type that repairs lung injuries when they occur.

Can nicotine cause scarring?

Taken together, these findings suggest that e-cigarettes containing nicotine can potentially cause lung fibroblasts to become overactive and ultimately create scarring. The results further suggest this can happen both in healthy people and in people whose fibroblasts already have a tendency to grow out of control, such as those with idiopathic pulmonary fibrosis.

What is the difference between evali and lipoid pneumonia?

a, bThe histologic distinction between exogenous lipoid pneumonia and electronic cigarette or vaping-associated lung injury (EVALI) is dramatic and distinctive. Exogenous lipoid pneumonia shows numerous lipid vacuoles a, most of which are much larger than individual cells. There is associated fibrosis in which many of the droplets are embedded. Occasional macrophages contain lipid droplets within their cytoplasm. However, the droplets are much larger and more variable (arrow) compared to EVALI, H&E, × 100. Larger lipid vacuoles are surrounded by several multinucleated giant cells and a foreign body giant cell reaction (arrowhead) b, a feature not seen in EVALI, H&E, × 200

What is an end vape?

ENDS, also known as E-cigarettes and vaping devices, were originally developed as a replacement device for conventional tobacco cigarette smokers [1]. However, their success in the arena of smoking cessation has been very limited, and they remain unapproved as cessation tools due to a lack of data demonstrating efficacy relative to currently approved nicotine replacement therapies [2]. The aerosols produced by E-cigarettes are known to cause a variety of deleterious health effects, although more research and long-term studies are still needed [2]. E-devices have rapidly evolved since entering the international market in 2013, with vape pens, box mods, and pod-based devices being the most commonly used vaping devices in 2020 [3]. Although E-cigarettes are used in conjunction with conventional tobacco by many cigarette smokers (dual users), their sole use in young adults and adolescents has skyrocketed [4]. This is concerning as use of tobacco products had been declining worldwide for over 50 years, and now, a new generation of nicotine addicts is being created through these novel vaping devices through the use of appealing flavors and packaging [5]. Even more concerning is that children and teenagers who use E-cigarettes are more likely to smoke conventional tobacco [6].

Is vaping a respiratory disease?

In the summer of 2019, an acute, mysterious, and deadly respiratory illness related to vaping emerged, primarily in young patients, in the USA. Cases increased dramatically and peaked in late September 2019. The Center for Disease Control and Prevention (CDC) termed the disease causing this epidemic E-cigarette or vaping product use-associated lung injury (EVALI). Prior to EVALI, vaping had been associated with a variety of different pulmonary presentations ranging from lipoid pneumonia to diffuse alveolar hemorrhage, but at low numbers. In this review, we discuss electronic nicotine delivery systems (ENDS) as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with a discussion on the practical impact EVALI has had on the practice of pathology.

Is vaping a lung disease?

Symptoms can initially mimic common pulmonary diagnoses pneumonia, but sufferers typically do not respond to antibiotic therapy. Differential diagnoses have overlapping features with VAPI, including COVID-19.

What is VAPI diagnosis?

As VAPI was, as of October 2019, a diagnosis of exclusion, a variety of respiratory diseases must be ruled out before a diagnosis of VAPI can be made. The differential diagnosis should include more common diagnostic possibilities, such as community-acquired pneumonia, as well as do-not-miss diagnoses, such as pulmonary embolism. Other commonly documented hospital diagnoses for cases of severe pulmonary disease associated with e-cigarette use have included acute respiratory distress syndrome (ARDS), sepsis, acute hypoxic respiratory failure, and pneumonitis. As of September 2019, distinctions were still being made between processes occurring in association with vaping or the use of nicotine-containing liquids and those considered as alternative diagnoses to VAPI. These processes include the following:

How does dabbing work for vaping?
