RESUMEN
Background/Aims@#The use of complementary and alternative medicine (CAM) is a global phenomenon, including inflammatory bowel disease (IBD) patients. We aimed to assess the change in prevalence and patterns of CAM use, and attitudes towards CAM over an 8-year time interval (2006 vs. 2014) among IBD patients in Korea. @*Methods@#A total of 221 IBD patients (CD=142, UC=79) were asked to complete a questionnaire regarding CAM at two time points: at enrollment (2006) and 8 years later (2014/2015). @*Results@#The proportion of patients ever using CAM increased significantly from 60.2% in 2006 to 79.6% in 2014 (P<0.001), while the proportion of current CAM users increased slightly (35.7% to 38.0%, P=0.635); 21.7% used CAM consistently at both time points. The proportion of patients who felt CAM was less effective (P<0.001) and more expensive (P=0.04) than conventional treatments increased over time. Also, the proportion among ever CAM users who perceived a positive effect from CAM significantly decreased in 2014 compared to 2006 (P=0.004). Higher education (adjusted odds ratio [aOR], 2.10), prior side effects to conventional therapies (aOR, 2.23), and prior use of corticosteroids (aOR, 2.51) were associated with CAM use. Interestingly, use of CAM before IBD diagnosis (aOR, 2.73) was significantly associated with consistent CAM use. @*Conclusions@#Although the attitudes toward CAM have become less favorable, the majority of IBD patients have experienced CAM with an overall increase of current CAM users over time. Moreover, more than half of current CAM users used CAM consistently over time.
RESUMEN
BACKGROUND/AIMS: The unique role of enzyme 5-lipoxygenase (5-LO) in the production of leukotrienes makes it a therapeutic target for inflammatory bowel disease (IBD). The aim of this study was to evaluate the effects of B-98, a newly synthesized benzoxazole derivatives and a novel 5-LO inhibitor, in a mouse model of IBD induced by dextran sulfate sodium (DSS). METHODS: C57BL/6 mice were randomly assigned to four groups: normal control, DSS colitis (DSS+saline), low dose B-98 (DSS+B-98 20 mg/kg) and high dose B-98 (DSS+B-98 100 mg/kg). B-98 was administered with 3% DSS intraperitoneally. The severity of the colitis was assessed via the disease activity index (DAI), colon length, and histopathologic grading. The production of inflammatory cytokines interleukin (IL)-6 was determined by RT-PCR. Th cells were examined for the proportion of Th1 cell, Th2 cell, Th9 cell, Th17 cell and Treg cell using intracellular cytometry. RESULTS: The B-98 group showed lower DAI, less shortening of the colon length and lower histopathologic grading compared with the DSS colitis group (p<0.01). The expression of IL-6 in colonic tissue was significantly lower in the B-98 groups than the DSS colitis group (p<0.05). The cellular profiles revealed that the Th1, Th9 and Th17 cells were increased in the DSS colitis group compared to the B-98 group (p<0.05). CONCLUSIONS: Our results suggest that acute intestinal inflammation is reduced in the group treated with B-98 by Th1, Th9 and Th17 involved cellular immunity.

BACKGROUND/AIMS: Helicobacter pylori (H. pylori) is causally associated with gastritis and peptic ulcer diseases. Recent data have demonstrated that triple therapy with amoxicillin, clarithromycin, and a proton pump inhibitor has an eradication rate of only 74~76% and new therapeutic protocols may be necessary. The aim of this study was to investigate the effects of Lactobacillus as supplementation to anti-H. pylori regimens on H. pylori eradication rates and therapy-associated side effects. MATERIALS AND METHODS: The PubMed, Medline and Korean Medical Database were searched in January 2012, with no language restrictions, for randomized controlled trials; additional references were obtained from reviewed articles. We included trials comparing Lactobacillus supplementation to placebo or no treatment during anti-H. pylori regimens. Meta-analysis was performed with Review Manager. RESULTS: Eleven trials involving a total of 1,107 participants met the inclusion criteria. Compared with placebo or no intervention, Lactobacillus given along with anti-H. pylori regimens significantly increased the eradication rate [84.7% vs. 78.8%, odds ratio (OR) 1.75, 95% confidence interval (CI) 1.26~2.42] and reduced the risk of overall H. pylori therapy related adverse effects (35.4% vs. 48.6%, OR 0.56, 95% CI 0.38~0.81), particularly of diarrhea (7.5% vs. 20.6%, OR 0.31, 95% CI 0.18~0.54), bloating (19.2% vs. 29.9%, OR 0.53, 95% CI 0.32~0.88) and taste disturbance (17.6% vs. 34.8%, OR 0.37, 95% CI 0.21~0.64). There were no significant differences between groups in the risk of other adverse effects. CONCLUSIONS: Our review suggests that supplementation with Lactobacilli could be effective in increasing eradication rates of anti-H. pylori therapy. Furthermore, Lactobacilli showed a positive impact on some H. pylori therapy-related side effects, particularly diarrhea, bloating and taste disturbance.
