Vaping associated lung injury is defined by a compatible clinical and radiological picture in a patient who smoked an electronic cigarette in the previous 90 days and after exclusion of other conditions, -notably infections. The severity varies from mild symptoms to -hypoxemic respiratory failure eventually leading to death. The clinical presentation includes general, respiratory and gastrointestinal symptoms. Laboratory findings show leukocytosis with elevated -inflammatory markers. Radiological features consist of bilateral ground-glass opacities with or without consolidation. Broncho-alveolar lavage can be used to refine the diagnosis and exclude an infection. Corticosteroids are at the center of therapy. Antibiotics are often given because of the initial suspicion of infection.
