Taylor, An Official ATS Clinical Practice Guideline: Interpretation of Exhaled Nitric oxide Levels (FENO) for Clinical Applications. Am J Respir Crit Care Med, 2011. 184(5): p. 602-615.
Comment: The ATS guideline published in September recommends FENO measurements for assessing and monitoring airway inflammation as well as identifying patients responsive to corticosteroids. Further, FENO is recommended for identifying non-adherence to ICS treatment.

Comment: Garriga et al show that neither spirometry nor beta-2 agonist treatment prior to FENO measurements (using NIOX MINO) affects the resulting values.

Comment: This clinical study demonstrates that FENO can be used to differentiate between two ICS/LABA combination treatments.

Comment: Kalliola et al have successfully used NIOX MINO for FENO measurements in children from the age of 4 (success rate 73%) with significant differences shown between asthmatics and healthy controls.

Comment: This study shows a correlation between high FENO levels and low adherence in children using ICSs. NIOX MINO was used in this study.

Comment: FENO measurements, using NIOX MINO or a competitor device, are shown to predict the persistence of asthma control in well controlled patients.

Comment: In this Lancet paper, FENO measurements were used to guide ICS treatment in pregnant women. The FENO guided group had a significantly lower exacerbation rate compared to the control group and experienced an improvement in quality of life.

Comment: High FENO values in children <2 years of age (obtained using a tidal breathing technique) are correlated to a positive asthma predictive index.

Comment: FENO, as a measure of inflammation, is here used to prove the superior effectiveness of ICS treatment vs anti-leukotriene treatment in children with mild-to-moderate asthma.
