E-cigarette or Vaping Product Use Associated Lung Injury Among Three Young Adults: A Retrospective Case Series From Delaware

Abstract Background: E-cigarette or vaping associated lung injury (EVALI) is a lung disease associated with an inflammatory response to the vaping fluid. Currently, diagnosis remains elusive without definitive biomarkers. Case presentation: Herein, we describe three cases of EVALI among 18- to 21-year-old patients ranging from mild to severe. All cases presented with a combination of respiratory, gastrointestinal, and constitutional symptoms. Oxygen support and level of medical care varied based on disease severity. Bilateral pulmonary opacities were observed on chest imaging
