“…Obstructive lung disease is based on the American Thoracic Society/European Respiratory Society criteria that recommends the fifth percentile of the distribution in a population of healthy lifelong nonsmokers as the lower limit of normal. One patient described in this study has been previously described (4). Continuous variables are presented at median and interquartile range (IQR) with 95% CI.…”

Introduction: Since their introduction, electronic cigarette use has increased and was even proposed as an alternative to traditional tobacco use. Recently, a series of patients with acute respiratory failure due electronic cigarette, or vaping, associated lung injury (EVALI) in 2019 has been described which has largely been attributed to tetrahydrocannabinol (THC) containing vaporizer itself, as well as vitamin E acetate. Several case series have been published regarding the acute presentation, diagnosis and management. In addition to diagnosis and management of EVALI, we sought to describe potential long-term effects of lung parenchyma in these patients. Methods: A retrospective review was performed on 16 patients with clinically diagnosed EVALI at OSF St Francis Medical Center between August 01 2019 and February 1 2020. Relevant demographic and clinical data were collected in patients diagnosed with EVALI. Results: Of the 16 patients in the study the median age (IQR) age was 25.25 (20-29) and 94% were male. The predominant presenting symptoms were dyspnea (94%), cough (56%), nausea 63%), vomiting (63%), abdominal pain (50%), diarrhea (50%), and fever (63%). 2 (13%) patients required endotracheal intubation. Common features of computerized tomography (CT) scan were bilateral diffuse ground glass opacity (93%), septal thickening (53%), and subpleural sparing (47%). Bronchoalveolar lavage (BAL) was obtained in 3 patients and all demonstrated neutrophil predominance of 69% (56-90). One BAL was significant for hemosiderin laden macrophages. Post hospital follow up pulmonary function tests were obtained in 3 and 2 of these were significant for obstructive lung disease. Conclusions: In this case series of patients diagnosed with vaping associated lung injury, obstructive lung disease may be seen on pulmonary function testing and surveillance of these patients should occur regardless of duration.
