Pulmonary Lipid-Laden Macrophages and Vaping

Abstract

Recent case clusters of a respiratory syndrome associated with e-cigarette use (vaping) have been identified, as now reported in the Journal by Layden et al.¹ We describe clinical features of six cases in Utah that help characterize this nascent syndrome. We present the most severe case in our series here; the remaining five are summarized in Table 1 and in the Supplementary Appendix, available with the full text of this letter at NEJM.org.
