Immunological disease Rhinitis

A follow-up study of 29 workers with TMAN-induced immunologic lung disease who had been moved to low-exposure jobs for more than 1 year revealed that workers with late asthma or late respiratory systemic syndrome had improved symptoms, improved pulmonary functions, and lower total antibody against TMAN-HSA. In contrast, 7 of 12 workers with asthma rhinitis continued to have moderate to severe symptoms, abnormal pulmonary functions, and elevated IgE against TMAN-HSA. Elevated IgE against TMAN-HSA appears to be a marker for the subpopulation of workers with asthma rhinitis that does not improve. 

All isocyanates are known to cause pulmonary toxicity. Isocyanates are the most common causes of occupational asthma and have led to the development of immediate or late asthma among workers. Isocyanates have caused bronchitis, rhinitis, conjunctivitis, chronic obstructive lung disease, contact sensitivity, dermatitis, allergic alveolitis, and immunologic hemorrhagic pneumonitis.29... 

Educational programmes are included in a European Academy of Allergology and Chnical Immunology document on the impact of allergic rhinitis on quality of life and other airway diseases [142 (Ilb)], and consist of the following.
