The following (very recent - Summer 2018) short article on Asthma Phenotytes caught my eye.
It highlights increased medication needs for overlapping asthma phenotypes.
Interestingly, it talks of low Eosinophils and also low FeNO as distinct phenotypes separate from high Eosinophils and high FeNO. It also singles out Obesity as a significant phenotype.
Thanks ‘in advance’ for any comments, as I’m pretty tied-up at present and may therefore not have time to respond to individual replies.
