The general public knows that asthma has a great impact on our quality of life, and serious can be fatal, patients with asthma symptoms are also very nervous, will promptly seek medical attention, but the nasal diseases are often considered to be irrelevant to the small problem, but do not know, allergic rhinitis, sinusitis, nasal polyps and other nasal diseases, if not effectively treated, will trigger, aggravate asthma. Allergic rhinitis, sinusitis, nasal polyps and other nasal diseases and asthma are clinically very common respiratory diseases, although the upper and lower respiratory tract, but has a similar pathogenesis: ① for the inflammatory diseases of the respiratory tract; ② for the dysregulation of the immune mechanism and the airway hyperreactivity caused by the ③ have similar inflammatory mediators (histamine, leukotrienes, etc.) and inflammatory cells (mast cells, eosinophils, macrophages and T-cells), but also have a similar inflammatory mediator (histamine, leukotriene, etc.) and inflammatory cells (mast cells, eosinophils, giant cells and T-cells). Eosinophils and T-cells); ④ have a definite genetic predisposition; ⑤ 80% to 90% of asthma patients have allergic rhinitis and sinusitis, nasal polyps and other nasal diseases, and the proportion of asthma in patients with allergic rhinitis can be as high as 50%, if there is no standardized treatment, there are about one-third of the patients in a number of years after the development of asthma, asthma patients with nasal disease episodes, will induce exacerbation of asthma attacks. As early as 1997, the idea of “one airway, one disease” was proposed between nasal diseases and asthma, and the concept of co-management of the two diseases has been accepted by more and more otolaryngologists and respiratory physicians. Therefore, for patients with allergic rhinitis, sinusitis, nasal polyps in the early stages of the disease, such as taking effective treatment measures not only help the treatment of the disease, but also to avoid the emergence of asthma.
