Helicobacter pylori can cause variety of upper gastrointestinal disorders such as peptic ulcer, mucosa associated lymphoid tissue (MALT)-lymphoma, and gastric cancer. The prevalence of H. pylori infection has significantly decreased in Korea since 1998 owing to active eradication of H. pylori. Along with its decrease, the prevalence of peptic ulcer has also decreased. However, the mean age of gastric ulcer increased and this is considered to be due to increase in NSAID prescription. Gastric cancer is one of the leading causes of cancer deaths in Korea and Japan, and IARC/WHO has classified H. pylori as class one carcinogen of gastric cancer. Despite the decreasing prevalence of H. pylori infection, the total number of gastric cancer in Korea has continuously increased from 2006 to 2011. Nevertheless, the 5 year survival rate of gastric cancer patients significantly increased from 42.8% in 1993 to 67% in 2010. This increase in survival rate seems to be mainly due to early detection of gastric cancer and endoscopic mucosal dissection treatment. Based on these findings, the prevalence of peptic ulcer is expected to decrease even more with H. pylori eradication therapy and NSAID will become the main cause of peptic ulcer. Although the prevalence of gastric cancer has not changed along with decreased the prevalence of H. pylori, gastric cancer is expected to decrease in the long run with the help of eradication therapy and endoscopic treatment of precancerous lesions.

The aims of this study were to assess the risk of tuberculosis (TB) and the status of latent tuberculosis infection (LTBI) in Korean patients with inflammatory bowel disease (IBD) receiving tumor necrosis factor (TNF)-alpha blockers. We reviewed medical records of 525 Korean IBD patients (365 TNF-alpha blocker naive and 160 TNF-alpha blocker exposed) between January 2001 and December 2013. The crude incidence of TB was significantly higher in IBD patients receiving TNF-alpha blockers compared to TNF-alpha-blocker-naive patients (3.1% vs. 0.3%, P=0.011). The mean incidence of TB per 1,000 patient-years was 1.84 for the overall IBD population, 4.89 for TNF-alpha blocker users, and 0.45 for TNF-alpha-blocker-naive patients. The adjusted risk ratio of TB in IBD patients receiving TNF-alpha blocker was 11.7 (95% confidence interval, 1.36-101.3). Pulmonary TB was prevalent in patients treated with TNF-alpha blockers (80.0%, 4/5). LTBI was diagnosed in 17 (10.6%) patients, and none of the 17 LTBI patients experienced reactivation of TB during treatment with TNF-alpha blockers. Treatment with TNF-alpha blockers significantly increased the risk of TB in IBD patients in Korea. De novo pulmonary TB infection was more prevalent than reactivation of LTBI, suggesting an urgent need for specific recommendations regarding TB monitoring during TNF-alpha blocker therapy.

There is no consensus on whether it is safe to re-administer tumor necrosis factor-alpha (TNFalpha) inhibitors in patients with rheumatoid arthritis (RA) or ankylosing spondylitis (AS) flared after withdrawal of TNFalpha inhibitors due to active tuberculosis (TB). We evaluated the safety of restarting anti-TNFalpha therapy in patients with TNFalpha-associated TB. We used data of 1,012 patients with RA or AS treated with TNFalpha inhibitors at Seoul St. Mary's Hospital between January 2003 and July 2013 to identify patients who developed active TB. Demographic and clinical data including the results of tuberculin skin tests (TST) and interferon-gamma releasing assays (IGRA) were collected. Fifteen patients developed active TB. Five cases were occurred in RA and 10 cases in AS. Nine of 15 patients had a negative TST or IGRA and 6 TST-positive patients had received prophylaxis prior to initiating anti-TNFalpha therapy. All patients discontinued TNFalpha inhibitors with starting the treatment of TB. Eight patients were re-administered TNFalpha inhibitors due to disease flares and promptly improved without recurrence of TB. TNFalpha inhibitors could be safely resumed after starting anti-TB regimen in patients with RA or AS.

OBJECTIVETo evaluate the clinical efficiency of selective cyclo-oxygenase-2 (COX-2) inhibitor compared to traditional nonselective NSAIDs for the prevention of heterotopic ossification (HO) after total hip arthroplasty (THA).

METHODSBy searching Medline, Embase, CENTRAL (Cochrane Central Register of Controlled Trials) and Science Citation Index et al, only randomised controlled studies of selective COX-2 inhibitors VS nonselective COX-1 and COX-2 inhibitors for the prevention of HO after THA were included. The quality assessment of included studies was evaluated according to the standard of the Cochrane Collaboration, and the data were analysised by statistic software Stata 10.0. The HO incidence of both groups in different degrees was compared.

RESULTSFour eligible randomised controlled trials of totally 808 patients were included. Meta-analysis results showed that no statistically significant difference was found in overall incidence of HO (RR = 1.08, 95% CI: 0.71-1.64,P = 0.73), incidence of moderate severe HO (Brooker II and III) (RR = 0.83, 95% CI: 0.48-1.42, P = 0.49) and any grade of Brooker classification between two groups. In all included studies, 16 patients receiving nonselective COX inhibitor (4.4%) discontinued treatment because of gastrointestinal toxicity,whereas 10 patients in the selective COX-2 inhibitor group (2.7%) discontinued for gastrointestinal side effects.

CONCLUSIONThe selective COX-2 inhibitors are as equally effective as nonselective NSAIDs for the prevention of HO after THA. Considering the side effects of nonselective NSAIDs, selective COX-2 inhibitors were recommend for the prevention of HO after THA.

Acute pancreatitis remains the most frequent complication of endoscopic retrograde cholangiopancreatography (ERCP), with reported incidence rates that have changed little over several decades. Patient- and procedure-related risk factors for post-ERCP pancreatitis (PEP) are well-defined. Effective measures to prevent PEP have been identified, including improvements in cannulation techniques and pancreatic stenting, as well as pharmacological intervention. Pharmacotherapy has been widely studied in the prevention of PEP, but the effect in averting PEP has been inconclusive. Although pharmacological prophylaxis is appealing, attempts to find an ideal drug are incomplete. Most available data on the efficacy of pharmacological agents for PEP prophylaxis have been obtained from patients at average risk for PEP. However, recently, a randomized prospective controlled trial of rectal nonsteroidal anti-inflammatory drugs (NSAIDs) to prevent PEP in high-risk patients was published. The results revealed that rectal indomethacin reduced the incidence of PEP significantly. Thus, rectal administration of diclofenac or indomethacin immediately before or after ERCP is used routinely to prevent PEP. However, additional studies with NSAIDs using large numbers of subjects are necessary to confirm the prophylactic effect of these drugs and to establish whether they act synergistically with other prophylactic interventions, including pancreatic stenting.

OBJECTIVETo compare the clinical effect of glucocorticoids and NSAID in the treatment of partial splenic embolization syndrome.

METHODSSixty patients with cirrhosis and spleen hyperactivity who developed partial splenic embolization syndrome after partial splenic embolization with Seldinger technique were randomized equally into two groups to receive treatments with intravenous dexamethasone or oral nonsteroidal anti-inflammatory drugs (NSAIDs). White blood cell counts, liver functions, fever duration, abdominal pain duration, hospital stay, and occurrence of upper gastrointestinal hemorrhage and spleen abscess were recorded and analyzed.

RESULTSIn dexamethasone group, the average fever duration, abdominal pain duration, and hospitalization days was 3.36∓2.31, 7.39∓4.00, and 11.48∓3.29 days, respectively, significantly shorter than those in NSAIDs group (5.72∓3.83, 9.59∓4.22, and 15.07∓7.93 days, respectively, P<0.05). Seven days after the operation, white blood cell count (×10(9)=L) significantly increased from 4.23∓5.09 to 8.49∓3.53 in dexamethasone group (P<0.05), and from 3.21∓1.33 to 6.52∓2.37 in NSAIDs group (P<0.05); the increment was more obvious in dexamethasone group (P<0.05). The two groups of patients showed no significant difference in liver functions after the operation. None of the patients developed upper gastrointestinal hemorrhage or spleen abscess.

CONCLUSIONIntravenous dexamethasone produces better therapeutic effect than oral NSAIDs in the management of partial splenic embolization syndrome.

OBJECTIVETo study the preventive effects of jinghua weikang capsule (JWC) on nonsteroidal anti-inflammatory drugs (NSAIDs) induced injury to the mucosa of the small intestine.

METHODSThirty-two Wistar rats were randomly divided into four groups, i.e., the blank control group, the model group, the JWC group, and the esomeprazole group. Diclofenac was administered to rats in the model group, the JWC group, and the esomeprazole group at the daily dose of 15 mg/kg. JWC and esomeprazole was respectively given to those in the JWC group, and the esomeprazole group one day ahead. Normal saline was given to rats in the blank control group. Rats were killed 3 days later. The pathological changes of the small intestine were observed by hematoxylin and eosin stain.

RESULTSCompared with the blank control group, the general score for the small intestine (4.63 +/-0.52 vs 0.00 +/-0. 00) and the pathological score (4.00 +/-0.90 vs 0.00 +/-0. 00) obviously increased in the model group, showing statistical difference (P <0.05). Compared with the model group, the general score for the small intestine (1.88 +/-0.99) and the pathological score (2.11 +/-1.11) obviously decreased in the JWG group, showing statistical difference (P <0.05). Compared with the model group, the general score for the small intestine (2.75 +/-1.28) and the pathological score (2. 30 +/-0.94) obviously decreased in the esomeprazole group, showing statistical difference (P <0.05).

CONCLUSIONJWC could prevent NSAIDs induced injury to the mucosa of the small intestine.

Crohn's disease is characterized by chronic transmural inflammation of the bowel and is associated with serious complications, such as bowel strictures, abscesses, fistula formation, and perforation. As neither medical nor surgical therapy provides a cure for Crohn's disease, the primary goals of therapy are to induce and maintain remission and prevent complications. As a biologic agent, infliximab, a monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn's disease that does not respond to other medical therapies or surgery. Infliximab has proven to be very effective for inducing and maintaining remission in Crohn's disease; however, infliximab treatment has several potential complications. Here, we report a case of free perforation following a therapeutic response after an initial dose of infliximab for Crohn's disease. This is the first case report describing a free perforation in a Crohn's disease patient after an initial dose of infliximab.
