One article defined sarcopenia with the help of total psoas muscle area (TPA) divided by square of the height, with cut-off values <545 mm2/m2 for males and <385 mm2/m2 for females [23], one article considered that sarcopenia in CD patients was induced by mediators of systemic inflammation and assessed the impact of IFX on muscle volume and muscle strength in correlation with decreasing inflammatory markers IL-6 and C-reactive protein (CRP) [20]. Here, IL6 is linked to sarcopenia.
