F.Background: The prevalence of allergy, asthma and airwayinflammation and hyperresponsiveness in elite athletes has increased overthe years and appears to vary between sport modalities. Although allergicand respiratory diseases have been extensively studied in enduranceathletes, especially swimmers and winter sports athletes, the prevalencein elite runners remains unknown.Objective: The aims of this study were to screen allergy symptoms inelite runners and to evaluate the airway responsiveness and airwayinflammatory cells in these athletes.Methods: One hundred and thirty elite runners were invited tocomplete the Allergy Questionnaire for Athletes (AQUA©), a validatedquestionnaire to screen allergy in athletes, in addition to answeringquestions related to training history, running distance per week and bestrace time in a marathon or half-marathon. A subgroup of 36 nonasthmaticathletes also performed the methacholine challenge test,sputum induction and cardiopulmonary exercise testing. Airwayinflammation was quantified via cellular airway infiltration.Results: The presence of allergy was based on the AQUA© totalscore, and athletes were classified as either AQUA+ or AQUA- (a score=5 or <5, respectively). Sixty-one athletes (60%) reported allergysymptoms, and no significant differences between the groups (AQUA+and AQUA-) were observed regarding gender, age, running experience,weekly training volume or best performance time in a half-marathon ormarathon (p>0.05). Most athletes presented airway inflammation witheosinophilic predominance (23.6%); however, only 8.3% of the eliterunners had a positive response to methacoline challenge.Conclusions: Our study demonstrated that elite runners have a highprevalence of allergy and eosinophilic airway inflammation withoutevidence of airway hyperresponsiveness; this finding was independent ofgender, age, quantity of training and performance. © 2014 Nova Science Publishers, Inc. All rights reserved.- Acute cardiopulmonary effects induced by the inhalation of concentrated ambient particles during seasonal variation in the city of Sao Paulo(2014) BRITO, Jose Mara de; MACCHIONE, Mariangela; YOSHIZAKI, Kelly; TOLEDO-ARRUDA, Alessandra Choqueta; SARAIVA-ROMANHOLO, Beatriz Mangueira; ANDRADE, Maria de Fatima; MAUAD, Thais; RIVERO, Dolores Helena Rodriguez Ferreira; SALDIVA, Paulo Hilario NascimentoAmbient particles may undergo modifications to their chemical composition as a consequence of climatic variability. The determination of whether these changes modify the toxicity of the particles is important for the understanding of the health effects associated with particle exposure. The objectives were to determine whether low levels of particles promote cardiopulmonary effects, and to assess if the observed alterations are influenced by season. Mice were exposed to 200 mu g/m(3) concentrated ambient particles (CAPs) and filtered air (FA) in cold/dry and warm/humid periods. Lung hyperresponsiveness, heart rate, heart rate variability, and blood pressure were evaluated 30 min after each exposure. After 24 h, blood and tissue samples were collected. During both periods (warm/humid and cold/dry), CAPs induced alterations in red blood cells and lung inflammation. During the cold/dry period, CAPs reduced the mean corpuscular volume levels and increased erythrocytes, hemoglobin, mean corpuscular hemoglobin concentration, and red cell distribution width coefficient variation levels compared with the FA group. Similarly, CAPs during the warm/humid period decreased mean corpuscular volume levels and increased erythrocytes, hemoglobin, hematocrit, and red cell distribution width coefficient variation levels compared with the FA group. CAPs during the cold/dry period increased the influx of neutrophils in the alveolar parenchyma. Short-term exposure to low concentrations of CAPs elicited modest but significant pulmonary inflammation and, to a lesser extent, changes in blood parameters. In addition, our data support the concept that changes in climate conditions slightly modify particle toxicity because equivalent doses of CAPs in the cold/dry period produced a more exacerbated response.
