Vape lund c
Stephen R Broderick, M.D. By now, it seems pretty clear that using e-cigarettes, or vaping, is bad for your lungs. But research about exactly how vaping affects the lungs is in the initial stages, says Johns Hopkins lung cancer surgeon Stephen Broderick.
E-cigarette or Vaping Use-Associated Lung Injury (EVALI)
At the time the article was last revised Daniel J Bell had no financial relationships to ineligible companies to disclose. Vaping-associated lung disease , or EVALI e-cigarette or vaping product use-associated lung injury , consists of patterns of inhalational pulmonary injury induced by electronic cigarettes also known as e-cigarettes, e-vaporizers, e-hookahs, vapes, vape pens. These products heat up a liquid containing nicotine in which case the device is formally also called an electronic nicotine delivery system ENDS or cannabinoids such as tetrahydrocannabinol or cannabidiol, in which case the process is also colloquially called "dabbing".
The user then inhales the aerosol generated. The incidence of lung illness among electronic cigarette users is unclear, but almost 3, hospitalized cases have been reported in the United States as of early , with multiple deaths 67 had been confirmed in 29 of the states 1. Most cases involved use of both nicotine and cannabinoid products 2. Most patients report last vaping in the week before symptom onset 3.
A majority of affected patients are young teens and 20s and male 3. These symptoms occur days to weeks prior to hospitalization, which is usually prompted by hypoxemia and, sometimes, progression to respiratory failure and acute respiratory distress syndrome 8. Laboratory evaluation typically demonstrates leukocytosis with a neutrophilic predominance 3. Pulmonary function tests PFTs are often consistent with an overall decrease in airflow and diffusing capacity.
Airflow tends to improve post-recovery whereas diffusing capacity does not Proposed surveillance case definitions from American public health authorities require the following criteria 8 :. Several pathologic patterns of lung injury have been reported in the setting of vaping 2 :. The entity is likely caused by a chemical exposure rather than an infectious agent , and the vast majority of cases have involved vaping products containing vitamin E acetate , which has been used as a thickening agent in the manufacture of illegal tetrahydrocannabinol-containing vapes 1, A frequent finding on bronchoalveolar lavage fluid is the presence of lipid-laden macrophages seen with oil red O staining 4,7,13,15, The most common finding is diffuse bilateral ground glass opacities 3,8,18 , with a basilar predominance and sometimes subpleural or lobular sparing 5, Specific patterns with radiologic-pathologic correlation are described separately:.
Many patients treated with systemic corticosteroids show clinical improvement 7, 8. Electronic nicotine delivery systems ENDS have been available in the USA since , however the first case report was not published until Articles: Subpleural sparing Vitamin E Drug-induced lung disease Diffuse ground-glass nodules Non-medical drug use radiological manifestations Tobacco use Inhalational lung disease Medical abbreviations and acronyms E Cases: Vaping-associated lung injury Vaping-induced lung injury.
