RATIONALE The developed world is currently facing an epidemic of obesity. With the increased prevalence of obesity has come the recognition that obesity is a risk factor for asthma. OBJECTIVES The purpose of this workshop was to bring together experts in the field of asthma, with experts in the field of obesity to review the current state-of-the-art(More)
BACKGROUND Allergic rhinitis and sinusitis are frequently associated with asthma. The purpose of this study was to determine the impact of self-reported allergic rhinitis and sinusitis on lower airway disease in a large cohort of participants with well-characterized asthma. METHODS A cohort study of participants in two trials of the American Lung(More)
BACKGROUND Obesity is associated with poor outcomes in many diseases, although recent data suggest that acute lung injury (ALI) is an exception. This is particularly interesting because obesity is marked by increased levels of proinflammatory mediators associated with increased morbidity and mortality in ALI. We hypothesized that cytokine response might be(More)
RATIONALE Obesity is a major risk factor for asthma; the reasons for this are poorly understood, although it is thought that inflammatory changes in adipose tissue in obesity could contribute to airway inflammation and airway reactivity in individuals who are obese. OBJECTIVES To determine if inflammation in adipose tissue in obesity is related to(More)
Obesity and asthma prevalence have been increasing over the past decade. Epidemiological evidence demonstrates that obesity results in an increased risk of developing incident asthma. Even modest levels of increased weight increase asthma risk. Recently published data suggest that obese asthma patients may represent a distinct phenotype of asthma. Obese(More)
Study Objectives The purpose of this study was to determine if asthma with rhinitis and asthma without rhinitis represent distinct forms of disease. Design We performed a prospective cross-sectional study. Participants The study included healthy controls, participants with asthma without rhinitis, and participants with both asthma and rhinitis.(More)
BACKGROUND The IL-1 family member IL-33 plays a critical role in type 2 innate immune responses to allergens and is an important mediator of allergic asthma. The mechanisms by which allergens provoke epithelial IL-33 secretion are still poorly understood. OBJECTIVE Based on previous findings indicating involvement of the NADPH oxidase dual oxidase 1(More)
BACKGROUND Obesity is a risk factor for asthma. Studies in mice suggest that the adipokines leptin and adiponectin affect asthmatic responses. The purpose of this study was to determine if adipokines associated with obesity are (1) altered in obese women with asthma compared to controls and (2) associated with increased cytokines and chemokines involved in(More)
BACKGROUND The relationship between obesity and asthma remains inadequately defined. Studies about how obesity affects asthma control and lung function show conflicting results. Additional focus on the effect of age as a modifier may make clearer the interaction between obesity and asthma phenotype. We sought to use a diverse and well-phenotyped cohort of(More)
BACKGROUND Recent literature suggests that obese critically ill patients do not have worse outcomes than patients who are normal weight. However, outcomes in extreme obesity (BMI ≥ 40 kg/m(2)) are unclear. We sought to determine the association between extreme obesity and ICU outcomes. METHODS We analyzed data from a multicenter international(More)
