Autoimmune pulmonary alveolar proteinosis with a history of vaping and vitamin E‐positive bronchoalveolar lavage

Abstract: Pulmonary alveolar proteinosis (PAP) can be due to primary autoimmune and secondary causes, including e-cigarette, or vaping, product use-associated lung injury. We present a 33-year-old male presenting with PAP and a history of vaping. Serum anti-granulocyte-macrophage colony-stimulating factor antibodies were present. Vitamin E (VE), but not VE acetate, was detected in bronchoalveolar lavage. This is the first report of potential association between vaping and autoimmune PAP.

“…For instance, there were increased IL-6 levels in the brain, and elevated IL-6 is involved in carcinogenesis. In a study of a 33-year-old male, Chua et al noted that vaping products may have interacted with endogenous proteins and indirectly trigger autoimmune pulmonary alveolar proteinosis [ 61 ] . However, one limitation to better understanding these interactions is that this patient had previously used cannabis and e-cigarettes.…”

“…At 11 weeks of age, JUUL + HDM-exposed offspring exhibited pulmonary inflammation compared to their respective air + HDM controls. Additionally, JUUL + HDM female offspring showed decreased methylation of the promoter region of the Il10ra gene Chen et al [60] Female BALB/c mice E-cigarette liquid without nicotine and e-cigarette liquid containing 18 mg/mL of nicotine TNF-a protein levels were increased in the electronic cigarette groups (compared to controls), and IL-1b was suppressed in adult offspring. Additionally, methylation increased in the e-cigarette liquid without nicotine (~3X) and e-cigarette liquid containing 18 mg/mL of nicotine (~2X) Chua et al…”
