Regarding biomarkers and disease control, a decreasing trend with poor asthma control was indicated for markers VCAM-1 (median 851.25 full control vs. 711.35 insufficient control; p = 0.133) and ADMA (median 0.46 full control vs. 0.40 insufficient control; p = 0.143). This evidence concerns the gene VCAM1 and asthma.
