Electronic cigarette, or vaping, product use-associated lung injury (EVALI) is an
acute, noninfectious pulmonary syndrome linked to recent use of electronic
nicotine-delivery systems and THC-containing vaping products, predominantly
affecting adolescents and young adults. Clinically, patients usually present with a
range of respiratory, gastrointestinal, and constitutional symptoms, while
laboratory tests often reveal elevated inflammatory markers. In this review, the
authors conducted a systematic review of original research, including clinical
cohorts, epidemiological investigations, computed tomography (CT) pattern
studies, bronchoalveolar lavage (BAL) toxicant analyses, experimental cell models,
and prospective follow-up. The researchers identified relevant literature through
database searches (PubMed; Google Scholar) to synthesize the most current
evidence. Imaging studies such as chest CT most frequently disclose organizingpneumonia-
spectrum patterns with bilateral ground-glass opacities and subpleural
or lobular sparing. Analysis of BAL fluid samples discloses the presence of vitamin
E acetate (VEA), which appears to be one of the possible damaging factors.
Additionally, experimental cell models demonstrated that similar substances may
cause an inflammatory response, injury to alveolar epithelium, and surfactant
dysfunction. Management should focus on the immediate cessation of vaping,
symptomatic treatment, and administering selective systemic corticosteroids once
infection is reasonably excluded. In severe cases, patients may require intensive care
therapy. Although short-term survival is generally favorable with contemporary
care, a substantial subset of survivors report persistent respiratory, cognitive, and
mental health sequelae at one year. Despite these insights, evidence remains largely
observational and heterogeneous; prospective, standardized studies are essential for
validation biomarkers and evaluating structured survivorship interventions.
