In adults with persistent severe asthma, serum κ and λ FLC were highly correlated with inflammatory outcomes reflecting T2 high endotype, including peripheral blood eosinophils as percentage of total counts and absolute values, with peripheral blood neutrophils as percentage of total counts and absolute values, and with serum CRP concentrations (Figure 7; Figure 8, Supplementary Figure S4, Supplementary Tables S3, S4; correlation table and p values correlation table supplementary files). This evidence concerns the gene CRP and asthma.
