Gastritis is the most common disease among Korean. The demand for the development of gastritis drugs has been increasing. Currently, however, there is no guideline available for the clinical evaluation of gastritis drugs worldwide. As a consequence, domestic and international pharmaceutical companies make errors in the drug development processes, and it becomes difficult for them to establish the scientific validity and objectivity of newly developed drugs. The objective of this study was to develop the Guideline for Clinical Trials Evaluation of Gastritis which can be used in improving the quality and consistency of clinical trials. First, we collected and reviewed the clinical trials on gastritis drugs that were available from Japan Pharmaceuticals and Medical Devices Agency and Korea Food and Drug Administration (KFDA), and investigated the recent research trends on clinical trials of gastritis drugs. Reviewers from KFDA and National Institute of Food and Drug Safety Evaluation and scientific experts from the pharmaceutical industries developed the guidelines through regularly scheduled meetings. Opinions and consultation from academic fields and industry experts were also obtained. This project will provide the clinical trial practitioners, investigator and reviewers the scientific and rational guidelines for performance and evaluation of clinical trials for gastritis drugs. Furthermore, we hope this guideline contributes to establishing the national competitiveness, improving the quality of clinical trial, and encouraging researches on drug development for gastritis.

Background: Colorectal polyps are common in Thailand, particularly in the northeastern region. The present study aimed to determine any correlation between Helicobacter pylori-associated gastritis and colorectal polyps in the Thai population. Materials and Methods: A total of 303 patients undergoing esophagogastroduodenoscopy with colonoscopy for investigation of chronic abdominal pain participated in this study from November 2014 to October 2015. A diagnosis of Helicobacter pylori associated gastritis was made if the bacteria were seen on histopathological examination and a rapid urease test was positive. Colorectal polyps were confirmed by histological examination of colorectal biopsies. Patient demographic data were analyzed for correlations. Results: The prevalence of colorectal polyps was 77 (25.4%), lesions being found more frequently in Helicobacter pylori infected patients than non-infected subjects [38.4% vs. 12.5%; Odds Ratio (OR) (95% CI): 2.26 (1.32 - 3.86), p < 0.01]. Patients with Helicobacter pylori - associated gastritis were at high risk of having adenomas featuring dysplasia [OR (95% CI): 1.15 (1.16 - 7.99); P = 0.02]. There was no varaition in location of polyps, age group, sex and gastric lesions with respect to Helicobacter pylori status. Conclusions: This study showed that Helicobacter pylori associated gastritis is associated with an increased risk of colorectal polyps, especially adenomas with dysplasia in the Thai population. Patients with Helicobacter pylori-associated gastritis may benefit from concurrent colonoscopy for diagnosis of colorectal polyps as a preventive and early treatment for colorectal cancer.

Sogunjung-tang (SGJT) is traditional herbal prescriptions used to treat abdominal pain. In this study, we evaluated the effect on inflammation and gastritis through SGJT formulation development. SGJT composition herbal medicine was boiled in water at 95~100℃ for 3 hours and then concentrated. Sogunjung-tang mix soft extract (STM) was prepared using pharmaceutical excipients such as purified water, sodium benzoate, β-cyclodextrin and CMC-Na. Anti-inflammatory experiment was conducted using STM and lipopolysaccharide (LPS) in RAW 264.7 cells. Cell survival was measured by MTT method. Nitric oxide (NO) was measured using griess reagents, and pro inflammatory cytokines were measured by enzyme-linked immunosorbent assay and RT-PCR. Also, we verified STM validity in acute gastritis using the ICR mouse. STM was administered oral for three days. And 150 mM HCl in 60% ethanol was oral administered 0.5 mL one hour after the last drug administration. Mice were sacrificed 1 hour after 150 mM HCl in 60% ethanol administration. The gastric mucosa was visually observed. STM were not toxic in RAW 264.7 cells. Treatment of STM inhibited the production of NO and inflammatory cytokine at the protein and mRNA levels. Also, in the acute gastritis model with the mouse, the treatment of STM improved gastric mucosal bleeding and edema. In summary, it was confirmed that the treatment of STM exerts anti-inflammatory and anti-gastritis effects. Therefore, we suggest that STM may provide a preclinical evidence for the prevention and treatment of inflammatory and gastritis diseases.

Objectives : Wiryeong-tang (WRT) is a traditional herbal medicine used to treat kidney-related diseases. However, the anti-inflammatory and anti-gastritis effect of Wiryeong-tang was not well known. Therefore, we experimented to confirmed the anti-inflammatory and anti-gastritis effects of Wiryeong-tang. Methods : The RAW 264.7 cells were pre treated with Wiryeong-tang mix soft extract (WRT-mse; 50, 100 and 200 ㎍/mL) for 1 hrs, and then incubated with lipopolysaccharide (LPS; 500 ng/mL). Cell viability was measured by the MTT method, and nitric oxide (NO) was measured with griess reagent. In addition, pro-inflammatory cytokines were measured by enzyme-linked immunosorbent assay (ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). For anti-gastritis effect in vivo, acute gastritis was induced using 150 mM HCl/60% ethanol used ICR mice. WRT-mse (133 mg/kg) was pre treated for 3 days and then treated with 150 mM HCl/60% ethanol 1 hrs later. Then gastritis was observed and inflammatory cytokines in the gastric tissue was measured. Results : The 8 marker components of the WRT-mse were determined by simultaneous analysis using HPLC. WRT-mse was not toxic and inhibited pro-inflammatory cytokines such as IL-1β, IL-6 and TNF-α at NO production, protein and mRNA levels. Also, it was confirmed that WRT-mse improved bleeding and edema in gastritis, and suppresses inflammatory cytokines. Conclusion : In summary, our results suggest that the treatment of the WRT-mse reduced and improved the 150 mM HCl/60% ethanol induced acute gastritis and the inflammation caused by LPS stimulation in RAW 264.7 cells. Therefore, this study may provide useful drug or clinical evidence for WRT-mse to prevent inflammation.

It was evaluated the inhibitory action of quercetin-3-O-${\beta}$-D-glucuronopyranoside (QGC) on reflux esophagitis and gastritis in rats. QGC was isolated from the herba of Rumex Aquaticus. Reflux esophagitis or gastritis was induced surgically or by administering indomethacin, respectively. Oral QGC decreased ulcer index, injury area, gastric volume, and acid output and increased gastric pH as compared with quercetin. Furthermore, QGC significantly decreased gastric lesion sizes induced by exposing the gastric mucosa to indomethacin. Malondialdehyde levels were found to increase significantly after inducing reflux esophagitis, and were reduced by QGC, but not by quercetin or omeprazole. These results show that QGC can inhibit reflux esophagitis and gastritis in rats.

Phlegmonous gastritis is a rare and rapidly progressive bacterial infection of the stomach wall, with a high mortality rate. Antibiotics with or without surgical treatment are required for treatment. We present a case in which phlegmonous gastritis occurred during the diagnostic evaluation of early gastric cancer. The patient showed improvement after antibiotic treatment, but attempted endoscopic submucosal dissection failed because of submucosal pus. We immediately applied argon plasma coagulation since surgical resection was also considered a high-risk procedure because of the submucosal pus and multiple comorbidities. However, there was local recurrence two years later, and the patient underwent subtotal gastrectomy with lymph node dissection. Considering the risk of incomplete treatment immediately after recovery from phlegmonous gastritis and that recurrent disease can be more difficult to manage, delaying treatment and evaluation until after complete recovery of PG might be a better option in this particular clinical situation.
