Nitrogen dioxide is an irritant of the mucous membrane linked with another air pollutant that causes pulmonary diseases such as obstructive lung disease, asthma, chronic obstructive pulmonary disease and sometimes acute exacerbation of COPD and in fatal cases, deaths. [2]
That can cause dangerous side effects in the long term, which is why doctors rarely prescribe oral corticosteroids for long-term asthma treatment. Another class of oral meds is called leukotriene ...
There is strong evidence that NO x respiratory exposure can trigger and exacerbate existing asthma symptoms, and may even lead to the development of asthma over longer periods of time. It has also been associated with heart disease, diabetes, birth outcomes, and all-cause mortality, but these nonrespiratory effects are less well-established. [29]
The role for eNO in other conditions is even less well established compared to asthma. Since asthma can be a cause of chronic coughing (it may even be the sole manifestation, such as in cough-variant asthma), studies have looked at whether eNO can be used in the diagnosis of chronic cough. [18] [19] [20] [21]
Acute harm due to NO 2 exposure is rare. 100–200 ppm can cause mild irritation of the nose and throat, 250–500 ppm can cause edema, leading to bronchitis or pneumonia, and levels above 1000 ppm can cause death due to asphyxiation from fluid in the lungs. There are often no symptoms at the time of exposure other than transient cough, fatigue ...
[5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer. [ 7 ] [ 6 ] It is the fourth-largest risk factor overall for human health [ 8 ] as 99% of people are exposed to harmful levels of air pollution. [ 9 ]
This reduces the capacity of the immune system to cause bronchoconstriction through nitric oxide signalling, which is the main root cause of asthma symptoms. [2] Bronchial thermoplasty is normally used to treat patients with severe persistent asthma who do not respond well to typical pharmacotherapy regimens. [3]
GERD may be common in difficult-to-control asthma, but according to one study, treating it does not seem to affect the asthma. [33] When there is a clinical suspicion for GERD as the cause of the asthma, an Esophageal pH Monitoring is required to confirm the diagnosis and establish the relationship between GERD and asthma.
