Abstract

Weight loss and malnutrition are commonly reported in inflammatory bowel disease (IBD), but differences between Crohn's disease (CD) and ulcerative colitis (UC) patients have rarely been pointed out. In this regard, a sample of 102 consecutive patients with a diagnosis of either CD (n = 63, 33 males) or UC (n = 39, 25 males) based on previously reported clinical, morphologic, and histopathologic criteria were studied. Twenty-six anthropometric and metabolic variables were measured upon admission. Body composition was assessed by both anthropometry and bioimpedance measurements, and energy expenditure and substrate oxidation were assessed by indirect calorimetry. The data were subjected to principal-component analysis and to factor rotation to derive a set of a few basic independent descriptors of the metabolic features of each subject. Six descriptors were found to be responsible for greater than 86% of the total sample variability and to associate very well with mutually disjoint subsets of the original variables. The six summarizing factors are listed in order of decreasing percentage of explained variation (size 41.8%, fatness 17.9%, fuel 12.2%, shape 5.4%, energy 5.2%, and steroid 3.9%). CD and UC patients differed significantly with respect to fatness (CD lower, P = .004) and carbohydrate (CHO) fuel preference (CD lower, P = .030). Hence, CD patients showed a reduced fat mass (FM) compared with UC patients, and from a metabolic point of view, too, CD and UC are not superimposable. In fact, the lower CHO oxidation (CHOox) rate and consequent preferential lipid utilization found in CD patients may be taken into account as a contributing cause of lipid tissue wasting and in planning therapeutic enteral regimens
