NFKB1 and serum lipopolysaccharide activity: After 72 weeks, changes in IAUC GLP-2 independently predicted the presence of CKD (OR = 0.49, 95%CI:0.21-0.73, p = 0.010) and eGFR changes [β(SE) = 0.510(0.007, p = 0.006] at end-of-treatment, In MASH, an impaired GLP-2 response to meals is associated with intestinal barrier dysfunction, endotoxemia and NF-kB-mediated systemic inflammation and may promote renal dysfunction and CKD.
