Abstract

BACKGROUND: Inflammatory mediator concentration was found to be increased in active inflammatory bowel disease, and this could be related to an insulin-resistant state. Moreover, glucocorticoids, which are widely used in the treatment of inflammatory bowel disease, are notoriously related to insulin resistance. AIM: To measure body composition, whole body glucose uptake and oxidation in Crohn's disease and ulcerative colitis patients with inactive disease. METHODS: All patients had clinical, ultrasound and biochemical assessment. Body composition was determined by isotopic dilution technique; basal metabolic rate and substrate oxidation were measured by indirect calorimetry. Insulin sensitivity was assessed by the euglycaemic hyperinsulinaemic clamp. Ten patients with inactive Crohn's disease (five males, aged 31.1 +/- 7.0 years) and 10 patients with inactive ulcerative colitis (five males, aged 33.4 +/- 8.8 years) participated in the study. Forty healthy subjects, matched for age and height were used as a control group. RESULTS: Crohn's disease patients showed lower BMI (P < 0.001), fat mass (P < 0.05) and respiratory quotient (P < 0.001) values compared to both ulcerative colitis and control subjects. No difference in peripheral glucose uptake (micromol/kg/min) was found between groups (respectively 42.5 +/- 6.78 in Crohn's disease, 40.2 +/- 8.00 in ulcerative colitis and 41.4 +/- 10.8 in control subjects). Glucose storage and oxidation did not differ between groups. CONCLUSION: Our data showed that inflammatory bowel disease patients in a remission phase of the disease activity had a whole body glucose uptake and oxidation similar to those of control subjects, probably due to fat-free mass preservation and low blood and tissue cytokine concentration
