Abstract

Asthma affects approximately 300 million people worldwide and is the leading cause of hospitalization in children in developed countries. This disease is incurable and often refractory to treatment in a significant number of patients. It has been the subject of research in attempt to understand its mechanisms. The prevalence of smoking among asthmatic patients is similar to the general population. Smokers with asthma have an accelerated decline in lung function, more severe asthma symptoms, increased number of hospitalizations and increase the risk of mortality after hospital admission for an episode of potentially fatal asthma compared with asthmatic nonsmokers. The impact of cigarette smoke on asthma remains controversial both clinically and experimentally. The objective of this study is to evaluate the inflammatory profile in immunoregulation caused by coexposition to cigarette smoke on pulmonary allergic inflammation induced previously ovalbumin (OVA). The effect of cigarette smoke on allergic pulmonary inflammation induced by OVA will be assessed by bronchial responsiveness, lung remodeling in pulmonary and systemic inflammatory cells and production of antigen-specific antibodies (IgG1, IgG2a and IgE) profile as well as the production of and modulating inflammatory cytokines.
