          Abstract

          RESUMEN La proteinosis alveolar pulmonar es una enfermedad difusa que se debe a la acumulación de surfactante en los alveolos y que puede causar disnea y de manera progresiva llegar a fallo respiratorio. Aunque generalmente es de etiología inmunitaria, existen casos secundarios y congénitos. La lesión pulmonar inducida por uso de cigarrillo electrónico (EVALI) es una entidad descrita recientemente y tiene múltiples expresiones clínicas e histopatológicas, entre las cuales solo un par de reportes presentan a la proteinosis alveolar pulmonar como parte del espectro. Describimos el caso clínico y el manejo de un individuo y analizamos los posibles mecanismos celulares que podrían generar esta asociación.

          ABSTRACT Pulmonary alveolar proteinosis is a diffuse disease due to the accumulation of surfactant in the alveoli that can cause dyspnea and progressively lead to respiratory failure. Although it is usually of immune etiology, there are secondary and congenital cases. E-cigarette induced lung injury (EVALI) is a recently described entity and has multiple clinical and histopathological expressions, among which only a couple of reports present pulmonary alveolar proteinosis as part of the spectrum. We describe the clinical case and management of one young man and analyze the possible cellular mechanisms that could generate this association.

          Vitamin E Acetate in Bronchoalveolar-Lavage Fluid Associated with EVALI

          The causative agents for the current national outbreak of electronic-cigarette, or vaping, product use-associated lung injury (EVALI) have not been established. Detection of toxicants in bronchoalveolar-lavage (BAL) fluid from patients with EVALI can provide direct information on exposure within the lung.

            Pulmonary alveolar proteinosis: progress in the first 44 years.

            Pulmonary alveolar proteinosis is a rare clinical syndrome that was first described in 1958. Subsequently, over 240 case reports and small series have described at least 410 cases in the literature. Characterized by the alveolar accumulation of surfactant components with minimal interstitial inflammation or fibrosis, pulmonary alveolar proteinosis has a variable clinical course ranging from spontaneous resolution to death with pneumonia or respiratory failure. The most effective proven treatment--whole lung lavage--was described soon after the first recognition of this disease. In the last 8 years, there has been rapid progress toward elucidation of the molecular mechanisms underlying both the congenital and acquired forms of pulmonary alveolar proteinosis, following serendipitous discoveries in gene-targeted mice lacking granulocyte-macrophage colony-stimulating factor (GM-CSF). Impairment of surfactant clearance by alveolar macrophages as a result of inhibition of the action of GM-CSF by blocking autoantibodies may underlie many acquired cases, whereas congenital disease is most commonly attributable to mutations in surfactant protein genes but may also be caused by GM-CSF receptor defects. Therapy with GM-CSF has shown promise in approximately half of those acquired cases treated, but it is unsuccessful in congenital forms of the disease, consistent with the known differences in disease pathogenesis.

              Electronic cigarettes disrupt lung lipid homeostasis and innate immunity independent of nicotine

              Electronic nicotine delivery systems (ENDS) or e-cigarettes have emerged as a popular recreational tool among adolescents and adults. Although the use of ENDS is often promoted as a safer alternative to conventional cigarettes, few comprehensive studies have assessed the long-term effects of vaporized nicotine and its associated solvents, propylene glycol (PG) and vegetable glycerin (VG). Here, we show that compared with smoke exposure, mice receiving ENDS vapor for 4 months failed to develop pulmonary inflammation or emphysema. However, ENDS exposure, independent of nicotine, altered lung lipid homeostasis in alveolar macrophages and epithelial cells. Comprehensive lipidomic and structural analyses of the lungs revealed aberrant phospholipids in alveolar macrophages and increased surfactant-associated phospholipids in the airway. In addition to ENDS-induced lipid deposition, chronic ENDS vapor exposure downregulated innate immunity against viral pathogens in resident macrophages. Moreover, independent of nicotine, ENDS-exposed mice infected with influenza demonstrated enhanced lung inflammation and tissue damage. Together, our findings reveal that chronic e-cigarette vapor aberrantly alters the physiology of lung epithelial cells and resident immune cells and promotes poor response to infectious challenge. Notably, alterations in lipid homeostasis and immune impairment are independent of nicotine, thereby warranting more extensive investigations of the vehicle solvents used in e-cigarettes.
