Core Tip

Core Tip: Combined assessment of intramuscular adipose tissue, C-reactive protein levels, skeletal muscle mass and hemoglobin status can effectively predict vedolizumab response in ulcerative colitis patients. Routine screening of these markers helps identify potential non-responders early, optimize individualized treatment regimens, and improve clinical management efficiency of ulcerative colitis.
