High and Frequent Dose of Dexlansoprazole and Amoxicillin Dual Therapy for Helicobacter pylori Infections: A Single Arm Prospective Study / 대한소화기학회지

BACKGROUND/AIMS: Recently, the eradication rate of Helicobacter pylori (H. pylori) infection has decreased to less than 80% worldwide with the use of clarithromycin-based triple therapy owing to the increased resistance of H. pylori to antibiotics, especially clarithromycin and metronidazole. This prospective study aimed to determine eradication rate of H. pylori following high and frequent doses of extended-release dexlansoprazole and amoxicillin, as a dual therapy in a region with high clarithromycin resistance rate. METHODS: A total of 50 treatment-naïve patients with active H. pylori infections, who were confirmed through via rapid urease test or histology and serology between November 2015 and February 2016 at our hospital, were included for analysis. All enrolled patients were treated with 750 mg amoxicillin and 30 mg dexlansoprazole, four times a day for a total duration of 14 days. Treatment success was determined using urea breath test four weeks after treatment completion. RESULTS: Seven out of the 50 patients (29 men and 21 women; mean age, 57 years) dropped out during the study. The total eradication rate was 52% (26/50), and that for those with a compliance rate of over 90% was 68.4% (26/38). H. pylori infections were not successfully eradicated in patients with a compliance rate of less than 90%. Nine patients (18%) reported side effects, such as mild diarrhea and abdominal fullness. No significant factors, such as smoking and alcohol consumption, affected the infection the eradication rate. CONCLUSIONS: High and frequent doses of proton pump inhibitor–amoxicillin dual therapy were not effective in eradicating H. pylori infection in a province with high clarithromycin resistance rate.

A Case of Pneumothorax Following Gastric Endoscopic Submucosal Dissection / 대한내과학회지

Endoscopic submucosal dissection (ESD) is widely accepted as an alternative treatment to surgical resection for gastric neoplastic lesions. Among the complications of gastric ESD, perforation is usually manifested as a pneumoperitoneum. Here, we report a patient with a right-sided pneumothorax, pneumoperitoneum, and pneumoretroperitoneum as complications of gastric ESD. The patient recovered without further complications using conservative treatment, including endoscopic clipping, nasogastric drainage, and insertion of a chest tube.

Clinical Outcomes of Argon Plasma Coagulation Therapy for Early Gastric Neoplasms

BACKGROUND/AIMS: Argon plasma coagulation (APC) has some merits in the treatment of gastric neoplasms including a shorter operative time and fewer complications compared with endoscopic mucosal resection or endoscopic submucosal dissection. However, there are few reports on the outcomes of gastric neoplasms treated using APC. The aim of this study was to evaluate APC in the treatment of early gastric neoplasms in terms of clinical efficacy, safety, and local recurrence. METHODS: We enrolled 28 patients who received APC therapy at the Kyungpook National University Hospital between May 2007 and April 2013. Clinical outcomes were analyzed. RESULTS: The median follow-up period was 24.8 months (range, 2 to 78). Among the 28 lesions treated using the APC procedure, tumor recurrence was encountered in seven lesions (25.0%). Recurrence was found in 50% (5/10) of single APC cases and 11% (2/18) of rescue APC cases. The mean time to recurrence was 16.1 months (range, 2 to 78). There were no serious APC-related complications such as perforation, bleeding, or infection. CONCLUSIONS: APC therapy can be a useful treatment with a favorable safety profile for patients with early gastric neoplasms. However, further studies are necessary to determine the long-term prognosis of patients undergoing this treatment.

A Case of Portal Vein and Splenic Vein Occlusion after Endoscopic Variceal Occlusion Therapy in Gastric Variceal Bleeding / 계명의대학술지

Acute gastric variceal bleeding is one of the most serious complications in portal hypertension, and is associated with high mortality and morbidity. Endoscopic variceal obturation (EVO) using Histoacryl(R) (n-butyl-2-cyanoacrylate) has been accepted as an effective hemostatic procedure in acute gastric variceal bleeding. However, EVO is not a widely performed because of technical difficulties and complications such as mucosal ulceration, perforation, and systemic embolism. Herein, we report a patient who developed hepatic failure caused by portal vein occlusion by Histoacryl(R) injection for management of gastric variceal bleeding.

The Effect of Concomittent Therarpy and Quadruple Therapy for Patients Who Had 23S Ribosomal Ribonucleic Acid Mutated Helicobacter pylori in Daegu and Kyoungpook Area

BACKGROUND/AIMS: Proton pump inhibitor (PPI) and two types of antimicrobial agents, amoxicillin, and clarithromycin have been widely used for the eradication of Helicobacter pylori. However, antibiotic resistant strains has rapidly increased and has emerged as an important factor for eraducation failure. MATERIALS AND METHODS: Patients diagnosed with chronic gastritis, peptic ulcer disease or gastric epithelial neoplasm was examined by H. pylori PCR for mutation at 23S rRNA. Positive H. pylori PCR without 23S rRNA mutation was eradicated by standard triple therapy. Patients with 23S rRNA mutation was eradicated by standard triple therapy or concomittent therapy with amoxicillin, PPI, clarithromycin and metronidazol or quadruple therapy with bismuth, PPI, tetracycline and metronidazol. We evaluated the predictors of eradication failure with regards to 23S rRNA mutation and initial eradication regimen. RESULTS: Nine hundred sixty-one patients were studied. H. pylori PCR was positive in 35.0% of the patients and 23S rRNA mutatation was found in 22.2% of the patients. The eradication rate of H. pylori for the A2143G point mutated group with standard triple therapy was 28.5% and significantly lower than 93.1% of the wild type group and 100% of the concomitant therapy group, 66.6% of one week quadruple group and 100% of two week quadruple group (P<0.005). CONCLUSIONS: When 23S rRNA point mutation was positive, the standard triple therapy was not effective and the eradication rates was only 22.2%. Alternative regimens should be considered when 23S rRNA point mutation is detected, especially when A2143G point mutation is detected because A2143G point mutation is highly related to eradication failure.

Adaptation Experience to Family of Immigrant Women in Multicultural Families

PURPOSE: This study was to explore adaptation experience to family among women who immigrated for marriage. Specific aims were to identify problems immigrant women face as family members and how they interact with other family members. METHODS: Grounded theory methodology was utilized. Data were collected from iterative fieldwork with individual in-depth interviews from 6 immigrant women as key informants, and 2 of their husbands and 2 of their mothers-in-law as general informants. RESULTS: Through constant comparative analysis, a core category emerged as "tearing down the wall in communicating". Causal conditions were feeling frustrated in one's expectations, differences in language and life style, differences in recognition, and perceptions of discrimination and prejudice. Strategies were learning the Korean language, learning Korean culture, managing stress, mediating differences between family members, and introspecting. Intervening factors were support systems, burdens of child-rearing, and the condition of one's health. Consequences were rooting oneself in one's family and accepting one's life as it is. CONCLUSION: Results of the study indicate that there is a need for nurses to understand differences in communication with family members among immigrant women and to provide information and emotional support to improve the adaptation of these women to their Korean families.
