Abstract:BackgroundLong-term management of bronchial asthma based on the fractional exhaled nitric oxide (FeNO) value alone is not conclusive yet. Therefore, we combined FeNO testing and spirometry, a commonly used test in routine practice, to evaluate acute exacerbation and respiratory function in children with bronchial asthma.ObjectiveWe combined FeNO testing and spirometry, commonly used in routine practice, to evaluate acute exacerbations and respiratory function in children with bronchial asthma.MethodsSubjects w… Show more
“…FE NO measurement could also be used in differentiating Cough-Variant Asthma (CVA) from other causes of chronic cough [83][84][85][86], to distinguish pre-school wheezing phenotypes and to assess the risk of later asthma or impaired lung growth and lung dysfunction in children [87].…”
Asthma prevalence in Italy is on the rise and is estimated to be over 6% of the general population. The diagnosis of asthma can be challenging and elusive, especially in children and the last two decades has brought evidences that asthma is not a single disease but consists of various phenotypes. Symptoms can be underestimated by the patient or underreported to the clinician and physical signs can be scanty. Usual objective measures, like spirometry, are necessary but sometimes not significant. Despite proper treatment asthma can be a very severe condition (even leading to death) however new drugs have recently become available which can be very effective in its control. Since asthma is currently thought to be caused by inflammation, a direct measure of the latter can be of paramount importance. For this purpose, the measurement of Fractional Exhaled Nitric Oxide (FENO) has been used since the early years of the current century as a non-invasive, easy-to-assess tool useful for diagnosing and managing asthma. This SIP-IRS/SIAAIC Position Paper is a narrative review which summarizes the evidence behind the usefulness of FENO in the diagnosis, management and phenotypization of asthma.

“…Severe eosinophilic asthma is a distinct but still imprecisely characterized subclassification of severe asthma involving the abnormal production of type 2 cytokines from Th2 and innate lymphoid cells [15]. In this issue, Saito et al [16] described that school-aged asthma children with high FeNO levels and lung dysfunction were at high risk of prolonged lung dysfunction.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
