CRP and cystic fibrosis: In addition, no significant differences were found for the inflammation markers (i.e., hs-CRP and IL-6), the oxidative stress markers (i.e., TBARS, ox-LDL, resistance of serum to oxidation, GPx in serum, and GPx in leukocytes), or the enzymes of PAF metabolism (i.e., LpPLA2, Lyso-PAF ATC, PAF-AH, PAF-CPT, and the LpPLA2-to-LDL ratio) between the CF/EF and the EF/CF groups at the beginning of the study (Table 1).
