EBC metabolomics for asthma severity.
Ntontsi P, Ntzoumanika V, Loukides S, Benaki D, Gkikas E, Mikros E, Bakakos P. Ntontsi P, et al. J Breath Res. 2020 Jul 3;14(3):036007. doi: 10.1088/1752-7163/ab9220. J Breath Res. 2020. PMID: 32392552
Amino-acid lysine was the only metabolite that discriminated the two study groups using NMR data (p= 0.04, t-test with Welch's correction, AUC 0.66). EBC is an easily available biofluid which directly represents the lower airways but difficult-to-use for metabolomic …
