Burnt sugarcane harvesting is associated with rhinitis symptoms and inflammatory markers

摘要: Abstract Introduction Burnt sugarcane harvesting requires intense physical exertion in an environment of high temperature and exposure to particulate matter. Objective To evaluate the effects burnt on rhinitis symptoms inflammatory markers workers. Methods A total 32 male workers were evaluated with questionnaire for symptoms, peripheral blood nasal lavage, non-harvesting, 3 6 months into period. Weather data matter fine concentrations measured same day. Results The 27 (23–33 μg/m3), 112 (96–122 μg/m3), 63 (17–263 μg/m3); 24 h temperatures 32.6 (25.4–37.4 °C), 32.3 (26.7–36.7 °C) 29.7 (24.1–34.0 °C) relative humidities 45.4 (35.0–59.7%), 47.9 (39.1–63.0%), 59.9 (34.7–63.2%) non-harvesting period, three age was 37.4 ± 10.9 years. prevalence significantly higher at period (53.4%), compared (26.7%; p = 0.039) (20%; p = 0.006). Concentrations interleukin (IL-6) lavage increased after (p = 0.012). presence directly associated eosinophils inversely neutrophils. Conclusions After work IL-6 increased. Furthermore, eosinophil counts concentration
