Vaping-Associated Lung Injury in a 28-Year-Old Male: A Case of Acute Hypoxic Respiratory Failure and Eosinophilic Pneumonitis

Suwanee, GA

BACKGROUND: Vaping-associated lung injury (VALI) has become a significant health issue, particularly among young adults who frequently use electronic cigarettes (e-cigarettes). Initially, VALI was associated with acute pulmonary symptoms following vaping. However, further studies have revealed a range of clinical manifestations, from mild respiratory distress to severe respiratory failure.

CASE PRESENTATION: A 28-year-old male with no significant past medical history who developed acute hypoxic respiratory failure following heavy vaping exposure. The patient presented to the emergency department with shortness of breath, productive cough, and chest tightness, along with eosinophilia and patchy ground-glass opacities on chest imaging. His symptoms were initially attributed to a bacterial infection, but further workup and clinical presentation suggested vaping-associated lung injury (VALI) or hypersensitivity pneumonitis. The patient was treated with steroids, nebulizer treatments, and oral antibiotics. His respiratory status improved, and he was discharged in stable condition with follow-up for pulmonary surveillance.

DISCUSSION: VALI is a growing concern due to the increasing use of e-cigarettes, especially among adolescents and young adults. VALI can present symptoms resembling pneumonia, asthma exacerbation, or hypersensitivity pneumonitis, which makes diagnosis challenging. This case emphasizes the importance of considering vaping as a potential cause of respiratory symptoms, especially in patients with no prior respiratory history but who engage in heavy vaping. This case also highlights the importance of eosinophilia as a diagnostic clue in cases of hypersensitivity pneumonitis or allergic reactions to inhaled substances.

CONCLUSION: This case highlights the critical importance of early diagnosis and appropriate management of vaping-associated lung injury (VALI) and hypersensitivity pneumonitis in young adults. Healthcare providers should maintain a high level of suspicion for vaping-related respiratory issues, especially when common causes like infections or asthma exacerbations have been ruled out.
