AIM: To determine the concentrations of leptin and ghrelin, which have opposite effects on appetite,energy expenditure, and weight control, in the plasma of patients with Crohn's disease (CD), which is often associated with weight loss and malnutrition.METHODS: Plasma leptin and ghrelin concentrations were determined in 28 outpatients with CD by radioimmunoassay. Age- and sex-matched controls with and without Helicobacter pylori(H pylori) infection (28for each) were enrolled in the study. Circulating levels of these hormones were assessed with respect to CD activity, disease localization and medical treatment.RESULTS: There were no significant differences in ghrelin levels between CD patients and H pylorinegative controls. However, circulating ghrelin levels were significantly lower in H pylori-infected subjects than in CD patients and uninfected controls. Plasma leptin levels were comparable among the groups. Localization and medication profile had no significant impact on circulating ghrelin and leptin levels.CONCLUSION: Apart from H pyloriinfection, CD itself has no significant influence on circulating ghrelin and leptin levels in the outpatients who were mostly in inactive state.

METHODS： Plasma leptin and ghrelin concentrations were determined in 28 outpatients with CD by radioimmunoassay. Age- and sex-matched controls with and without Helicobacter pylori （H pylori） infection （28 for each） were enrolled in the study. Circulating levels of these hormones were assessed with respect to CD activity, disease localization and medical treatment.
RESULTS： There were no significant differences in ghrelin levels between CD patients and H pylori- negative controls. However, circulating ghrelin levels were significantly lower in Hpylori-infected subjects than in CD patients and uninfected controls. Plasma leptin levels were comparable among the groups. Localization and medication profile had no significant impact on circulating ghrelin and leptin levels.
CONCLUSION： Apart from H pylori infection, CD itself has no significant influence on circulating ghrelin and leptin levels in the outpatients who were mostly in inactive state.
