OBJECTIVES Recent studies in animal models of sepsis-induced acute respiratory distress syndrome (ARDS) have shown that a low-carbohydrate, high-fat diet combining the anti-inflammatory and vasodilatory properties of eicosapentaenoic acid (EPA; fish oil), gamma-linolenic acid (GLA; borage oil) (EPA+GLA), and antioxidants improves lung microvascular(More)
Although chronic eosinophilic pneumonia is a well-known disorder, acute eosinophilic pneumonia has not been as well characterized. We describe the clinical features, results of bronchoalveolar lavage, and follow-up studies of four patients with acute eosinophilic pneumonia. The patients presented with an acute febrile illness, severe hypoxemia (partial(More)
BACKGROUND Previous uncontrolled reports have suggested that HIV-seropositive persons develop an accelerated form of emphysema. OBJECTIVE To characterize the risk for emphysema in a stable HIV-seropositive outpatient population. DESIGN Controlled, cross-sectional analysis. SETTING Midwestern urban community. PARTICIPANTS HIV-seropositive persons (n(More)
Small amounts of plasma protein normally reach the alveolar epithelial surface by a size-selective process that restricts the passage of very large molecules. Size selectivity may be compromised in the lungs of patients with the adult respiratory distress syndrome (ARDS). To assess this question, bronchoalveolar lavage fluid (BALF) from normal volunteers (n(More)
The adult respiratory distress syndrome (ARDS) is a devastating clinical illness characterized by refractory hypoxemia and high-permeability pulmonary edema. Reactive oxygen species may play a key role in the pathogenesis of the acute lung injury. Glutathione is a tripeptide that is able to react with and effectively neutralize oxidants, such as hydrogen(More)
The adult respiratory distress syndrome (ARDS) is a devastating clinical illness characterized by refractory hypoxemia and high-permeability pulmonary edema. Reactive oxygen species such as hydrogen peroxide and hypochlorous acid may play a key role in the pathogenesis of the acute lung injury. Glutathione (GSH) is a tripeptide that is able to react with(More)
Numerous reports have demonstrated that prior to the development of acquired immunodeficiency syndrome (AIDS)-related pulmonary complications, human immunodeficiency virus-positive (HIV+) individuals commonly develop unexplained reductions in pulmonary diffusing capacity (DLCO). The potential relevance of this observation is underscored by recent data(More)
STUDY OBJECTIVES Recent evidence suggests that chronic or latent viral infection may be an important predisposing factor in the development of COPD among smokers. As such, understanding if HIV-seropositive smokers are at heightened risk for respiratory symptoms may have relevance with regard to COPD pathogenesis. The current study was done to systematically(More)
Glutathione is an important antioxidant tripeptide that is found in high concentrations in the epithelial lining fluid (ELF) of the lung. Previous investigators demonstrated a deficiency of glutathione (GSH) in the epithelial lining fluid of human immunodeficiency virus (HIV)-seropositive patients. The current investigation performed bronchoalveolar lavage(More)
OBJECTIVE Previously, we showed that acute respiratory distress syndrome patients fed an enteral diet containing eicosapentaenoic acid and gamma-linolenic acid and elevated antioxidants (EPA+GLA; Oxepa) had significantly reduced pulmonary inflammation, increased oxygenation, and improved clinical outcomes. In a subset of acute respiratory distress syndrome(More)
