BackgroundMalnutrition among inflammatory bowel disease (IBD) may arise from factors including inadequate dietary intake, malabsorption, and progression of disease. IBD has been reported an increased prevalence of low bone mass. The aims of the present study were to evaluate the nutritional status and to investigate the correlation between bone mineral density (BMD) and nutrient factors in patients with IBD.MethodsA total of 41 subjects were classified into normal group (n=21) and malnourished group (n=20) by the subjective global assessment result. We surveyed the dietary habit, nutrient intake, and BMD.ResultsSubjects' average age was 36.7 years old, and included 26 ulcerative colitis and 15 Crohn's disease. The serum C-reactive protein (CRP) was significantly higher and serum calcium was significantly lower in the malnourished group. Lower bone density subjects were more in the malnourished group but no significant difference. Intake of energy, protein, carbohydrate, fiber, iron, sodium, potassium, zinc, vitamin B6, vitamin C and folate were significantly lower in the malnourished group. The BMD of malnourished group showed correlation with triceps skin fold thickness (TSF), CRP, dietary calcium, phosphorous, iron, animal iron, zinc and vitamin.ConclusionsThe results suggested that adequate intake of nutrients is important to prevent bone loss and systemic education programs are need for IBD patients.

Background/AimsThe pathogenesis of bone loss in patients with inflammatory bowel disease (IBD) is complex, multifactorial, and only partly understood. We aimed to examine the extent and risk factors of bone mass reduction and to analyze the impact of early onset of a disease before attaining peak bone mass in IBD patients.MethodsWe compared the risk factors for osteoporosis and BMD at the lumbar spine and the hip bone in IBD patients.ResultsA total of 44 patients with IBD were enrolled. Twenty-one and 23 patients were diagnosed as IBD before and after the age of 30 and designated as group A and group B, respectively. Group A had significant bone mass reduction at the lumbar spine than group B (BMD, 1.01±0.10 vs. 1.14±0.17, p<0.01; T-score, -1.22±0.84 vs. -0.08±1.39, p<0.01; Z-score, -1.11±0.81 vs. -0.03±1.32, p<0.01, respectively). Multivariate analysis showed that patients diagnosed as IBD before the age of 30 had possible risk factor of bone mass reduction (hazard ratio, 3.96; p=0.06).ConclusionsBone mass reduction was more severe in patients who were diagnosed with IBD before the age of 30 than in those diagnosed after the age of 30.

Background/Aims: The impact of Helicobacter pylori (H. pylori) eradication after endoscopic resection (ER) of early gastric cancer (EGC) has not been fully evaluated. We tried to find out the effect of H. pylori eradication therapy on the development of metachronous gastric cancers and changes in Cyclooxygenase-2 (COX-2) expression following attempts to eradicate H. pylori after ER of EGC. Materials and Methods: We eradicated H. pylori in the patients with EGC after ER. Biopsy samples were taken according to the follow-up schedules for surveillance after ER. Results: Fifty five patients were enrolled and finished the follow up schedules. Of the 55, 28 were successfully treated H. pylori infection, and the other 27 were failed eradication of H. pylori. The mean follow-up period was 60.8 months. Five in the H. pylori ongoing infection group developed metachronous gastric cancer, whereas no new gastric cancers were found in the 28 eradication group (P=0.023). COX-2 expression in the eradication group was significantly decreased (1.4±0.2, n=28), compared to that in H. pylori ongoing infection group (3.0±0.4, n=27, P=0.0001) after the follow-up. Conclusions: The eradication of H. pylori seems to have a preventative effect on the development of metachronous adenocarcinomas and a suppressive effect on COX-2 expression in the patients after ER for EGC.
