Analyzing preoperative laboratory studies (serum albumin and CRP) and other patient characteristics (such as the rate of sarcopenia, BMI, SMI, and height) by IBD subtypes revealed that the rate of sarcopenia was significantly higher in patients with CD than in those with UC (60.7% vs. 36.7%, p = 0.044) [24, 29]. The gene discussed is ALB; the disease is inflammatory bowel disease.
