Case series: Adolescent victims of the vaping public health crisis with pulmonary complications.

Alongside the epidemic use of electronic cigarettes (e-cigarettes) across the country, evidence of multiple pulmonary complications has emerged, with the most immediately life-threatening being the new clinical condition of e-cigarette/vaping-associated lung injury (EVALI), with investigation actively underway to further define this entity and determine the cause or causes. We present a series of cases of respiratory illnesses associated with e-cigarette use, many of which meet criteria for suspected or confirmed EVALI, managed at a pediatric tertiary care center, demonstrating notable variation in presenting symptoms and severity. Most cases improved with supportive respiratory care and the administration of corticosteroids and antibiotics, although generally no infection was found. The cases also tend to show improvement with discontinuation of the use of e-cigarettes. We discuss challenges in determining the contribution of e-cigarettes to the case pathology and review possible diagnostic and treatment options. In patients suffering from e-cigarette-related respiratory illness including EVALI, the primary treatment goal should be the cessation of e-cigarette use and avoidance of other possible pulmonary toxins, including conventional cigarettes. Prevention of e-cigarette use is critical in the youth population, as these patients are typically nicotine naive and do not engage in smoking conventional cigarettes before initiation of vaping.
