AI Article Synopsis
- * The review analyzed 115 papers, concluding that low levels of nasal NO (nNO) are indicative of primary ciliary dyskinesia (PCD) and can aid in diagnosis when symptoms align.
- * In addition to PCD, the study found low nNO levels in conditions like chronic rhinosinusitis and cystic fibrosis, while higher levels were seen in allergic rhinitis, though its diagnostic and prognostic roles in these diseases remain unclear.
Article Abstract
Nitric oxide (NO) is produced within the airways and released with exhalation. Nasal NO (nNO) can be measured in a non-invasive way, with different devices and techniques according to the age and cooperation of the patients. Here, we conducted a narrative review of the literature to examine the relationship between nNO and some respiratory diseases with a particular focus on primary ciliary dyskinesia (PCD). A total of 115 papers were assessed, and 50 were eventually included in the review. nNO in PCD is low (below 77 nL/min), and its measurement has a clear diagnostic value when evaluated in a clinically suggestive phenotype. Many studies have evaluated the role of NO as a molecular mediator as well as the association between nNO values and genotype or ciliary function. As far as other respiratory diseases are concerned, nNO is low in chronic rhinosinusitis and cystic fibrosis, while increased values have been found in allergic rhinitis. Nonetheless, the role in the diagnosis and prognosis of these conditions has not been fully clarified.
