Lung injury associated with an e-cigarette (vaping) use during the COVID-19 pandemic

In recent years, the excessive use of electronic cigarettes (e-cigarettes), and vaping, as a re-placement for traditional tobacco cigarettes, have highlighted potential health risks for users. One such risk is the development of "electronic cigarette (vaping) product use-associated lung injury" (EVALI). This type of lung injury has an unclear cause that may be related to the various components found in e-cigarette fluids. The Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection (coronavirus disease . 2019 or COVID-19) may worsen EVALI symptoms in individuals with both conditions. This could be due to the increased oxidative stress and inflammation caused by e-cigarette use, as re-search shows increased levels of reactive oxygen species (ROS) and decreased glutathione. In this paper, we present two critical cases of COVID-19 patients with a history of chronic e-cigarette smoking and describe their clinical progression during hospitalization. The findings suggest that their prolonged use of e-cigarettes may have sig-nificantly impacted the severity of the disease.Copyright © 2023, The Indonesian Foundation of Critical Care Medicine.

Where There Is (No) Smoke, There Is Still Fire: a Review of Trends, Reasons for Use, Preferences and Harm Perceptions of Adolescent and Young Adult Electronic Cigarette Use.

Purpose of the review: To review the current prevalence, trends, perceptions, and effects of e-cigarette or vaping product use associated lung injury (EVALI) on e-cigarette use among US adolescents and young adults. Recent findings: COVID-19 diagnosis was more likely among the current/ever dual cigarette and e-cigarettes users, as well as ever e-cigarette only users. Additionally, the EVALI outbreak may have influenced harm perceptions, as daily nicotine vaping declined significantly from 2019 to 2020, and more youth and young adults perceived vaping as harmful. Summary: The prevalence of e-cigarette use, specifically flavored use, remains high among adolescents and young adults, which is concerning due to the short-term and unknown long-term effects of e-cigarettes and their association with future cigarette and other substance use.

E-cigarette or Vaping product use Associated Lung Injury (EVALI) in a 15 year old female patient - case report.

BACKGROUND: E-cigarettes are devices which allow to aerosolize liquids containing nicotine or other substances. Ever since they were released on the market in 2006, the number of users have been constantly increasing, especially among adolescents, ranging from 7,6% to 9,3% in the age group 18-24 years old from 2014 to 2019. Hand in hand with the spread of E-cigarettes many have been the efforts to understand their impact on health. EVALI (E-cigarette or Vaping product use Associated Lung Injury) is an emerging condition with a heterogeneous presentation with several reported cases worldwide. We mean to report a case of EVALI in a 15-year-old female Caucasian patient, who's currently attending her clinic follow-up at Bambino Gesù Pediatric Hospital in Rome. CASE PRESENTATION: The patient was admitted to the Emergency Room due to acute respiratory failure in November 2020. At admittance, she was severely dyspneic (HR 120 bpm, SatO2 75%). As she was hospitalized amid the COVID-19 pandemics, she underwent a nasopharyngeal swab for SARS-CoV2, which turned out negative, and a chest CT scan. Chest CT scan showed a central ground grass pattern with peripheral sparing. At the anamnestic recall, it was disclosed she was an e-cigarette smoker and occasional marijuana user. The microbiological work-up proved only positive for Rhinovirus. Her clinical and radiological case was discussed with our radiologist who suspected EVALI. She was assisted through HFNC, antibiotical therapy and corticosteroids with a dramatic recovery within the first 48 h. CONCLUSIONS: EVALI started being recognized a specifically nosological entity in summer 2019, with increasing cases being reported. No diagnostic criteria have been agreed upon yet, but its usual presentation includes respiratory, gastrointestinal and systemic symptoms of different degree and the diagnosis can be hypothesised in case the patient has an evocative clinical and radiological presentation and has been an E-cigarette smoker in previous 90 days. Due to the novelty of the condition and its heterogeneous presentation it is of interest to report the cases in which EVALI is identified to raise awareness about this emerging new-age disease.

Prospectively Assessed Long-Term Outcomes of Patients with E-Cigarette- or Vaping-associated Lung Injury.

Rationale: E-cigarette- or vaping-associated lung injury (EVALI) was first identified in 2019. The long-term respiratory, cognitive, mood disorder, and vaping behavior outcomes of patients with EVALI remain unknown. Objectives: To determine the long-term respiratory, cognitive, mood disorder, and vaping behavior outcomes of patients with EVALI. Methods: We prospectively enrolled patients with EVALI from two health systems. We assessed outcomes at 1 year after onset of EVALI using validated instruments measuring cognitive function, depression, anxiety, post-traumatic stress, respiratory disability, coronavirus disease (COVID-19) infection, pulmonary function, and vaping behaviors. We used multivariable regression to identify risk factors of post-EVALI vaping behaviors and to identify whether admission to the intensive care unit (ICU) was associated with cognitive, respiratory, or mood symptoms. Results: Seventy-three patients completed 12-month follow-up. Most patients were male (66.7%), young (mean age, 31 ± 11 yr), and White (85%) and did not need admission to the ICU (59%). At 12 months, 39% (25 of 64) had cognitive impairment, whereas 48% (30 of 62) reported respiratory limitations. Mood disorders were common, with 59% (38 of 64) reporting anxiety and/or depression and 62% (39 of 63) having post-traumatic stress. Four (6.4%) of 64 reported a history of COVID-19 infection. Despite the history of EVALI, many people continued to vape. Only 38% (24 of 64) reported quitting all vaping and smoking behaviors. Younger age was associated with reduced vaping behavior after EVALI (odds ratio, 0.93; P = 0.02). ICU admission was not associated with cognitive impairment, dyspnea, or mood symptoms. Conclusions: Patients with EVALI, despite their youth, commonly have significant long-term respiratory disability; cognitive impairment; symptoms of depression, anxiety, post-traumatic stress; and persistent vaping.

Environmental Factors.

The acute respiratory distress syndrome (ARDS) remains a major cause of morbidity and mortality in the intensive care unit. Improving outcomes depends on not only evidence-based care once ARDS has already developed but also preventing ARDS incidence. Several environmental exposures have now been shown to increase the risk of ARDS and related adverse outcomes. How environmental factors impact the risk of developing ARDS is a growing and important field of research that should inform the care of individual patients as well as public health policy.

E-cigarette or Vaping Product Associated Lung Injury (EVALI) Presenting As Cardiac Arrest.

E-cigarettes or vaping products became available in the market in 2004. Since then, their use has rapidly increased in all sections of society. They have been increasingly used as a "safer" alternative for combustible cigarettes and as an aid toward smoking cessation. Over time, the acceptability of e-cigarettes in public spaces increased. Lack of regulatory control also led to a rapid rise in the rate of e-cigarette/vaping product users. We report a case of a 35-year-old female who recently switched from conventional cigarettes to e-cigarette usage, and who presented to the emergency department after an out-of-hospital cardiac arrest. She was found to have bilateral extensive nodular ground-glass opacities on a CT angiogram of the chest. She needed non-invasive ventilation and was initially started on broad-spectrum antibiotic treatment for possible pneumonia. Due to a worsening clinical status, e-cigarette or vaping product associated lung injury (EVALI) diagnosis was considered, and she was started on parenteral steroid therapy, leading to rapid recovery in respiratory status. With a tapering course of steroid therapy and cessation of e-cigarette use, there was complete clinical and radiological recovery. This case highlights that EVALI can have varied clinical presentations, and the diagnosis should be considered in anyone who presents with an acute cardio-pulmonary decline and a concomitant history of e-cigarette use.

E-vape and E-Cigarettes-Associated Lung Injury (EVALI) in the COVID-19 Pandemic: A Diagnostic Dilemma and Therapeutic Challenge.

E-vape and e-cigarettes-associated lung injury (EVALI) is a diagnostic dilemma and even more obscure during the coronavirus disease 2019 (COVID-19) pandemic. A rise was seen in EVALI cases at the beginning of the COVID-19 pandemic. Still, the non-specific presentation, or the overlapping symptoms of COVID-19 and EVALI, can negate the possible diagnosis of EVALI because of a clinician's predisposition toward infectious etiologies, and it becomes even more challenging during a viral pandemic. The patient's social history remains the key distinctive point in diagnosing EVALI. Systemic steroids are generally used along with supportive care to treat patients with EVALI. This case report demonstrates the dilemma in diagnosing EVALI in a 19-year-old female during the COVID-19 pandemic.

Health effects and known pathology associated with the use of E-cigarettes.

In recent years, new nicotine delivery methods have emerged, and many users are choosing electronic cigarettes (e-cigarettes) over traditional tobacco cigarettes. E-cigarette use is very popular among adolescents, with more than 3.5 million currently using these products in the US. Despite the increased prevalence of e-cigarette use, there is limited knowledge regarding the health impact of e-cigarettes on the general population. Based on published findings by others, E-cigarette is associated with lung injury outbreak, which increased health and safety concerns related to consuming this product. Different components of e-cigarettes, including food-safe liquid solvents and flavorings, can cause health issues related to pneumonia, pulmonary injury, and bronchiolitis. In addition, e-cigarettes contain alarmingly high levels of carcinogens and toxicants that may have long-lasting effects on other organ systems, including the development of neurological manifestations, lung cancer, cardiovascular disorders, and tooth decay. Despite the well- documented potential for harm, e-cigarettes do not appear to increase susceptibility to SARS-CoV- 2 infection. Furthermore, some studies have found that e-cigarette users experience improvements in lung health and minimal adverse effects. Therefore, more studies are needed to provide a definitive conclusion on the long-term safety of e-cigarettes. The purpose of this review is to inform the readers about the possible health-risks associated with the use of e-cigarettes, especially among the group of young and young-adults, from a molecular biology point of view.

Modeled Respiratory Tract Deposition of Aerosolized Oil Diluents Used in Δ9-THC-Based Electronic Cigarette Liquid Products.

Electronic cigarette, or vaping, products (EVP) heat liquids ("e-liquids") that contain substances (licit or illicit) and deliver aerosolized particles into the lungs. Commercially available oils such as Vitamin-E-acetate (VEA), Vitamin E oil, coconut, and medium chain triglycerides (MCT) were often the constituents of e-liquids associated with an e-cigarette, or vaping, product use-associated lung injury (EVALI). The objective of this study was to evaluate the mass-based physical characteristics of the aerosolized e-liquids prepared using these oil diluents. These characteristics were particle size distributions for modeling regional respiratory deposition and puff-based total aerosol mass for estimating the number of particles delivered to the respiratory tract. Four types of e-liquids were prepared by adding terpenes to oil diluents individually: VEA, Vitamin E oil, coconut oil, and MCT. A smoking machine was used to aerosolize each e-liquid at a predetermined puff topography (volume of 55 ml for 3 s with 30-s intervals between puffs). A cascade impactor was used to collect the size-segregated aerosol for calculating the mass median aerodynamic diameter (MMAD) and geometric standard deviation (GSD). The respiratory deposition of EVP aerosols on inhalation was estimated using the Multiple-Path Particle Dosimetry model. From these results, the exhaled fraction of EVP aerosols was calculated as a surrogate of secondhand exposure potential. The MMAD of VEA (0.61 µm) was statistically different compared to MCT (0.38 µm) and coconut oil (0.47 µm) but not to Vitamin E oil (0.58 µm); p < 0.05. Wider aerosol size distribution was observed for VEA (GSD 2.35) and MCT (GSD 2.08) compared with coconut oil (GSD 1.53) and Vitamin E oil (GSD 1.55). Irrespective of the statistical differences between MMADs, dosimetry modeling resulted in the similar regional and lobular deposition of particles for all e-liquids in the respiratory tract. The highest (~0.08 or more) fractional deposition was predicted in the pulmonary region, which is consistent as the site of injury among EVALI cases. Secondhand exposure calculations indicated that a substantial amount of EVP aerosols could be exhaled, which has potential implications for bystanders. The number of EVALI cases has declined with the removal of VEA; however, further research is required to investigate the commonly available commercial ingredients used in e-liquid preparations.

A Comprehensive Review of Vaping Use in Pediatric Patients and Recent Changes in Regulatory Laws.

The use of electronic cigarettes (e-cigarettes), also known as vapes, by adolescents and young adults has dramatically increased over the past several years. E-cigarettes continue to be the most used form of tobacco among youth. As a result of this concerning trend, policies at both the state and federal levels have been implemented to limit availability in this population. Additionally, the coronavirus disease 2019 (COVID-19) pandemic has had some positive and negative effects on the youth vaping epidemic with adolescent consumers reporting limited access to retail sites during the stay-at-home executive orders, but easier access with online purchasing because age verification was often not required. Complications resulting from vaping have been reported and include e-cigarette or vaping product use-associated lung injury (EVALI) and thrombotic events. Data suggest that the use of vaping devices can lead to both short- and long-term respiratory morbidity in the pediatric population. This review serves to provide a comprehensive examination of vaping use in pediatric patients and recent changes in regulatory laws to equip pharmacists with the knowledge to be aware of the different devices and products available, ask their pediatric patients regularly about use, and counsel and educate on the potential harmful effects.

E-cigarette or vaping product use associated lung injury (EVALI) in the time of COVID-19: A clinical dilemma.

AIM: To report on the clinical, laboratory, and radiological findings of adolescents who presented during the SARS-CoV-2 surge with symptoms of Coronavirus disease 2019 (COVID-19), did not test positive for the infection, and were diagnosed with E-cigarette and vaping product use associated lung injury (EVALI). METHODS: A retrospective review of 12 cases of EVALI admitted to the Bristol Meyers Squibb Children's Hospital between February 2020 and June 2020 was conducted. RESULTS: The ages of the patients ranged from 14 to 19 years. There were six males and six females. Three patients had a past history of anxiety, depression, or other psychiatric/mental health disorder, 9 had prolonged coagulation profile (prothrombin time, partial thromboplastin time, and/or International Normalized Ratio), and 11 had elevated inflammatory markers. Eight needed respiratory support. All 12 were negative for SARS-CoV-2 PCR. Four were tested for IgG antibodies and were negative. As these cases were admitted to rule out COVID infection, initial treatment included hydroxychloroquine. Steroids were started only after SARS-CoV-2 PCR was shown to be negative. Urine tetrahydrocannabinol was positive in all cases. Chest X-ray and computed tomography findings showed ground glass opacities. CONCLUSIONS: Clinical and radiological features are similar in both EVALI and SARS-CoV-2 infection. Inflammatory markers are elevated in both conditions. A detailed social and substance use history in patients presenting with "typical" COVID pneumonia like illness is important. EVALI should be ruled in early to start the appropriate treatment. Given the ongoing pandemic, pediatricians and other health-care providers need to be aware of other conditions that can masquerade as SARS-CoV-2.

COVID or Not COVID? A Great Mimicker Behind the Smoke Screen.

Vaping is becoming increasingly popular as an alternative to cigarettes. However, vaping does not come without risks; electronic cigarette (e-cigarette) and vaping-associated lung injury (EVALI) is one of the most severe consequences. Coronavirus disease 2019 (COVID-19) and bacterial pneumonia cases often present with almost identical features. We present a case of a young man who presented with pneumonia that was initially thought to be related to COVID-19 infection but later diagnosed as EVALI. Clinicians should have a high suspicion of EVALI in patients who present with hypoxemia and negative infectious workup, particularly during the COVID-19 era. Administration of corticosteroids has shown remarkable efficacy in improving hypoxemia; however, many patients may have chronic lung injury and may require oxygen long-term. Cases of EVALI should continue to be reported and followed up long term for monitoring disease outcomes.

E-cigarette or vaping product use-associated lung injury: A great COVID-19 mimicker in young adult.

EVALI and COVID-19 share similar clinical and imaging features. Assessing the vaping or e-cigarette use history and conducting urine toxicology tests for high-risk patients are important with increasing COVID-19 cases in young adults.

E-cigarette, or vaping, product use associated lung injury and the risks and benefits of a thorough infectious work-up.

As of February 2020, over 2800 cases of lung injury associated with vapes have been reported in all 50 states (Cullen et al., 2019) [1]. This case is about a 29-year-old female with a five-year history of vaping tetrahydrocannabinol (THC) who presented with symptoms consistent with e-cigarette, or vaping, product-use associated lung injury (EVALI). This case report is unique because this patient clinically improved on a lower dose of corticosteroids compared to other reported cases of EVALI. Additionally, this case report highlights the importance and difficulty of excluding other disease processes prior to treating patients for EVALI, particularly during the coronavirus disease 2019 (COVID-19) global pandemic.

Vaping, SARS-CoV-2, and Multisystem Inflammatory Syndrome: A Perfect Storm.

The use of electronic cigarettes (e-cigarettes) and vaping among adolescents has risen exponentially in the last decade. E-cigarette flavors has driven adolescents to use these convenient, USB-like devices, designed to create a desired social image, while being seemingly unaware of the serious health consequences of their behavior. Vaping impacts protective pulmonary barriers by attenuating the mucociliary clearance and by increasing peribronchial inflammation and fibrosis. The recent SARS-CoV-2 (COVID-19) pandemic has been characterized by a plethora of unusual disease presentations. Among them, a unique presentation seen exclusively in children and adolescents was multisystem inflammatory syndrome (MIS-C). Seventy percent of adolescents who had MIS-C also had acute respiratory distress syndrome (ARDS), and we speculate that there may exist common denominator that links MIS-C and adolescents: the use of e-cigarettes. The virus targets the angiotensin converting receptor (ACE receptor), and studies have shown nicotine-based e-cigarettes or vaping cause oxidative stress and resulting in the upregulation of ACE2, which might worsen ARDS in MIS-C. Our mini-review highlights that adolescents using e-cigarette have alterations in their pulmonary defenses against SARS-CoV-2: an upregulation of the ACE2 receptors, the primary target of SARS-CoV-2. Their compromised immune system makes them more uniquely vulnerable to Covid-19 related MIS-C, increasing their risk for ARDS and related morbidities. Currently, studies have shown an association between MIS-C and vaping, we speculate that adolescents who vape/smoke might be especially vulnerable to serious respiratory symptoms if they develop a hyper-inflammatory state MIS-C.

Pulmonary Toxicity and Inflammatory Response of E-Cigarette Vape Cartridges Containing Medium-Chain Triglycerides Oil and Vitamin E Acetate: Implications in the Pathogenesis of EVALI.

Recently, there has been an outbreak associated with the use of e-cigarette or vaping products, associated lung injury (EVALI). The primary components of vaping products, vitamin E acetate (VEA) and medium-chain triglycerides (MCT), may be responsible for acute lung toxicity. Currently, little information is available on the physiological and biological effects of exposure to these products. We hypothesized that these e-cig vape cartridges and their constituents (VEA and MCT) induce pulmonary toxicity, mediated by oxidative damage and inflammatory responses, leading to acute lung injury. We studied the potential mechanisms of e-cig vape cartridge aerosol induced inflammatory response by evaluating the generation of reactive oxygen species by MCT, VEA, and cartridges and their effects on the inflammatory state of pulmonary epithelium and immune cells both in vitro and in vivo. Cells exposed to these aerosols generated reactive oxygen species, caused cytotoxicity, induced epithelial barrier dysfunction, and elicited an inflammatory response. Using a murine model, the parameters of acute toxicity to aerosol inhalation were assessed. Infiltration of neutrophils and lymphocytes was accompanied by significant increases in IL-6, eotaxin, and G-CSF in the bronchoalveolar lavage fluid (BALF). In mouse plasma, eicosanoid inflammatory mediators, leukotrienes, were significantly increased. Plasma from e-cig users also showed increased levels of hydroxyeicosatetraenoic acid (HETEs) and various eicosanoids. Exposure to e-cig vape cartridge aerosols showed the most significant effects and toxicity compared to MCT and VEA. In addition, we determined SARS-CoV-2 related proteins and found no impact associated with aerosol exposures from these tested cartridges. Overall, this study demonstrates acute exposure to specific e-cig vape cartridges induces in vitro cytotoxicity, barrier dysfunction, and inflammation and in vivo mouse exposure induces acute inflammation with elevated proinflammatory markers in the pathogenesis of EVALI.

The consequential impact of JUUL on youth vaping and the landscape of tobacco products: The state of play in the COVID-19 era.

JUUL is a groundbreaking electronic cigarette (e-cig) and the preeminent vaping product on the market. We present an overview of the rapid and spectacular rise of JUUL and its remarkable fall within the timespan of 2015 - 2020. We highlight JUUL's entering the market in June 2015, becoming the industry leader in mid 2017, and experiencing a litany of setbacks by late 2019 through to early 2020. We address the role played by JUUL in the ongoing epidemic of youth vaping. We also feature competing views on the public health impact of JUUL use (in particular), and e-cig vaping (in general). We further highlight the latest trends in youth vaping and sales records for JUUL and tobacco cigarettes. In view of the ongoing pandemic of COVID-19, we briefly summarize the existing evidence on the relationship between vaping and smoking and the prevalence, disease course, and clinical outcomes of COVID-19.

Assessing Vaping Views, Usage, and Vaping-Related Education Among Medical Students: A Pilot Study.

Background E-cigarette use, or vaping, is known to be associated with potentially life-threatening lung injury, with the Centers for Disease Control and Prevention reporting 2,807 hospitalizations and 68 deaths in the United States due to e-cigarette or vaping-associated lung injury. Vaping is also a risk factor for and is implicated in the spreading of COVID-19. Despite the consequences of vaping, the views and training of medical students regarding vaping is unclear. This study sought to investigate the knowledge and perception of vaping amongst future health care providers. Methods An anonymous, online survey was administered to 259 first through fourth year medical students at Nova Southeastern University Dr. Kiran C. Patel College of Osteopathic Medicine via a secure website link in October 2019 and January 2020. The survey consisted of two sections. All participants answered section one, involving nine questions. This first section addressed sociodemographic characteristics, personal views on vaping, rating and impact of vaping medical education, and whether students had ever tried vaping. If students had ever vaped, they proceeded to section two of the survey including nine additional questions. Students that reported no past vaping use ended the survey and did not proceed to section two. Section two focused on evaluating vaping habits of users by questioning age of first usage, use frequency and nature, reasons for first trying and/or continuing to use, plans for quitting, personal impact of use, and current use. Data was analyzed with frequency and percentage distributions. Results Most respondents were of age 18-25 years (66.8%) and female (60.2%). Almost all students (96.5%) were aware of the negative health consequences of vaping. More than two thirds of students (68.7%) rated their vaping medical education as inadequate and the majority (76.1%) indicated their medical school curriculum did not impact their view on the matter. Most students (71.0%) reported a more negative stance on vaping due to recent news and media. Of the respondents, over two thirds (37.5%) vaped at least once and were labeled "vapers." The most commonly stated reason for first trying vaping was recreational (60.8%). Half of vapers (50.5%) admitted to vaping in the past year and most vapers (90.6%) did not think their vaping impacted others. Current vaping use was reported in almost one-third of vapers (32.3%) despite knowing its dangers, and several (6.3%) did not consider vaping dangerous. Conclusion The findings from this pilot study conducted at a single medical school indicate possible deficiencies in vaping education, at least as perceived by the respondents and demonstrated by their vaping-related actions. It is unknown if the stated vaping views and practices of these medical students would be positively impacted by better vaping education or if these practices are generalizable to other students. However, the data suggests there is a need to consider more extensive analyses of medical school curriculums with respect to vaping education and training of students in these and related areas. Recommendations to enhance medical school curriculums include vaping-focused respiratory and gastrointestinal lectures, problem-based case studies on vaping, standardized patient encounters, and a community education program taught by medical students.

EVALI - E-Cigarette or Vaping Product Use-Associated Lung Injury: A Case Report.

The use of electronic cigarettes among the young adult and adolescent population has increased over the past decade. Vaping is the process of inhaling an aerosol that is produced by heating a liquid or wax containing substances, such as nicotine, cannabinoids (e.g., tetrahydrocannabinol (THC), cannabidiol), flavoring, and additives (e.g., glycerol, propylene glycol) using an e-cigarette. A multistate epidemic associated with vaping prompted the Centers for Disease Control and Prevention (CDC) to issue an official health advisory on e-cigarette or vaping product use-associated lung injury (EVALI). EVALI is a diagnosis of exclusion with no specific diagnostic test. We present a case of EVALI before the COVID-19 pandemic time in a 23-year-old immunocompetent male student with an eight-year history of vaping. He presented to the emergency department with fever, shortness of breath, tachypnea, nausea, and diarrhea. The patient had no past medical history. The patient denied illicit drug abuse or known drug allergies. The patient was admitted with a diagnosis of sepsis and pneumonia. The patient's urine drug screen was positive for cannabinoids with a history of vaping. Community-acquired pneumonia due to Legionella, Pneumococcal, Mycoplasma bacteria was ruled out. Influenza A/B, Parainfluenza, Rhino, and Adenoviruses were negative. A computed tomographyscan of the chest showed bilateral infiltrates. He was treated with high dose steroids, empiric antibiotics, high flow oxygen and managed in ICU for seven days. The patient was discharged on tapering doses of steroid and counseled to quit vaping. EVALI outbreak is strongly linked to vitamin E acetate in vaping products. EVALI is a diagnosis of exclusion with a history of vaping and responds well to steroids.

EVALI: A Mimicker of COVID-19.

E-cigarette or vaping product use-associated lung injury (EVALI) is a respiratory illness that has significant overlap with the symptoms of coronavirus disease 2019 (COVID-19). In the current pandemic, diagnosis of EVALI may be delayed because of anchoring bias when patients present with symptoms consistent with COVID-19. We present 3 cases of patients who were hospitalized with a presumed diagnosis of COVID-19 but were later diagnosed with EVALI.
