• Tobacco smoke linked with respiratory diseases 

Tobacco smoke is involved in uncontrolled asthma, a diminished response to anti-asthma drugs, rhinitis, nasal obstruction, and deregulation of the immune system according to an international expert at the annual meeting of the American College of Allergy, Asthma and Immunology (ACAAI) in Miami Beach, Fla.

Tobacco smoking has been mainly associated with chronic obstructive pulmonary disease (COPD), and is attributed to being one of the main reasons that COPD disease is the fourth leading cause of death in the United States.

"Recent studies have shown that smoking can be linked with other respiratory diseases such as asthma exacerbations and rhinitis," said Carlos Baena-Cagnani, M.D., faculty of medicine, at Catholic University of Cordoba in Argentina. "Both active and passive smoking has been shown to be involved in uncontrolled asthma and associated with asthma exacerbations in children and adolescents."

According to Dr. Baena-Cagnani, active smoking also causes changes in inflammation in asthma patients, diminishes their response to anti-asthma drugs, and has been found to induce nasal obstruction and decreased mucociliary clearance.
