The pathogenesis of inflammatory bowel disease (IBD) is not well-understood; however, increased and persistent intestinal inflammation, due to inappropriate immune responses that are caused by interactions between genetic factors, gut microbiota, and environmental factors, are thought to lead to IBD. Various studies have identified more than 240 genetic variants related to IBD. These genetic variants are involved in innate and adaptive immunity, autophagy, defective bacterial handing, interleuki

BACKGROUND/AIMS: Infliximab is currently used for the treatment of moderate-to-severe ulcerative colitis (UC) with an inadequate response to conventional agents. The efficacy and safety of infliximab in Korean patients with UC were assessed. METHODS: This was a retrospective multicenter study including all adult patients who received at least one infliximab infusion for UC. Short- and long-term clinical outcomes and adverse events of infliximab therapy were evaluated, and predictors of response

PEG-Asc plus simethicone use was more effective and associated with better patient and endoscopist tolerance than PEG-Asc use. Therefore, this combination is recommended as one of the promising methods for bowel preparation before colonoscopy.

The authors conclude that epirubicin, cisplatin, and oral UFT plus leucovorin, a convenient regimen, has a significant activity and tolerable toxicities in patients with gastric carcinoma.

Terlipressin-induced hyponatremia occurred frequently, especially in young patients with good liver function and higher Na level. Caution is required when administering terlipressin to patients with low body mass index.

SPMC is as effective as conventional high-volume PEG-electrolyte solution in Korean patients. SPMC groups reported superior palatability and tolerability compared to PEG groups.

Crohn's disease (CD) is an idiopathic inflammatory bowel disease involving the small and/or large intestine. More than 50% of Western CD patients and up to 88% of Asian CD patients may have small intestinal involvement. Video capsule endoscopy (VCE) has a higher diagnostic yield than small bowel barium radiography and computed tomography enterography for the detection of small intestinal involvement of CD. VCE also provides diagnostic yields comparable to magnetic resonance- (MR-) based enterogr

Ulcerative colitis is an idiopathic inflammatory bowel disease characterized by colonic mucosal inflammation and chronic relapsing episodes. The initial therapeutic approach depends on both the extent of colonic involvement and the severity of the disease process at presentation. The mainstay of ulcerative colitis therapy is the administration of 5-aminosalicylic acid (5-ASA) or steroid. Additional medical therapy or colectomy should be considered if the patient remains symptomatic despite conve

The aim of this study was to evaluate whether PCR-based restriction fragment length polymorphism (RFLP) analysis was effective in differentiating between reinfection and recrudescence of H. pylori strains. Following a 1-2 week regimen of omeprazole 20 mg, amoxicillin 1.0 g, and clarithromycin 500 mg twice daily, twenty patients with duodenal ulcer were enrolled in the study. Ten patients (group 1, control) were not successfully treated, and another 10 patients (group 2) exhibited recurrence of i

Patient compliance during bowel preparation is important for successful colonoscopy. Bowel preparation with polyethylene glycol (PEG), the most commonly used solution for cleansing, involves the unpleasant ingestion of a large amount of liquid. Sodium picosulfate magnesium citrate (SP-MC) solution is an alternative option with better palatability than PEG. Therefore, in this study, we compared the efficacy and patient tolerability among the following three bowel preparation protocols: 2 L PEG-as

TJP-008 is a new low-volume cleansing agent with a colon cleansing efficacy comparable to that of standard 2LPEG that exhibits significant safety and tolerability.

In HBeAg-positive CHB patients infected with genotype C HBV, preC variant was associated with enhanced host immune response with lower HBV DNA levels, whereas CP variants were associated with severe liver damage and liver fibrosis progression.
