Trends in Helicobacter pylori eradication rates by first-line triple therapy and related factors in eradication therapy

BACKGROUND/AIMS: Trends in successful eradication of Helicobacter pylori using first-line triple therapy, consisting of a proton pump inhibitor, amoxicillin, and clarithromycin, have been understudied. We evaluated H. pylori eradication rates at a single center over the last 10 years and identified risk factors related to eradication failure. METHODS: This study included 1,413 patients who were diagnosed with H. pylori infection and received 7 days of triple therapy between January 2003 and December 2012. We investigated H. pylori eradication rates retrospectively with respect to the year of therapy, as well as demographic and clinical factors. H. pylori eradication was confirmed by a 13C-urea breath test or a rapid urease test at least 4 weeks after the completion of triple therapy. RESULTS: The overall H. pylori eradication rate was 84.9%. Annual eradication rates from 2003 to 2012 were 93.5%, 80.0%, 87.2%, 88.5%, 92.0%, 88.3%, 85.7%, 84.1%, 83.7%, and 78.8%, respectively, by per-protocol analysis. The eradication rate with first-line triple therapy decreased during the last 10 years (p = 0.015). Multivariate analysis showed that female gender (odds ratio [OR], 1.69; 95% confidence interval [CI], 1.12 to 2.55) and smoking (OR, 1.61; 95% CI, 1.05 to 2.47) were associated with the failure of H. pylori eradication therapy. CONCLUSIONS: The efficacy of first-line triple therapy for H. pylori infection has decreased over the last 10 years, suggesting an increase in antibiotic-resistant H. pylori strains. Thus, other first-line therapies may be necessary for H. pylori eradication in the near future.

Gastric Mucosal Injury after Ingestion of a Hot Liquid Diet via Gastric Feeding Tube / 대한소화기내시경학회지

When a patient complains of gastrointestinal symptoms such as nausea, vomiting, and upper abdominal pain after ingestion of a substance such as a corrosive agent and certain drugs which can cause mucosal injury to the esophagus and stomach, we always keep in mind gastrointestinal injury and should perform an endoscopic procedure promptly and use the appropriate treatment. It is well known that common corrosive agents which can cause gastrointestinal injury are acidic and alkaline chemicals, and the common causative drug for gastrointestinal injury is NSAID. However, it is not well known that consuming hot food and drinks can cause gastrointestinal injury also. Up to now, there have only been a few case reports of esophageal mucosal injury due to the consumption of hot food and drinks. Gastric mucosal injury after ingesting hot food and drinks is rare and has not been reported often. So here, we report a case of gastric mucosal injury after ingesting a hot liquid diet via gastric feeding tube.

A Case of Intracardiac Metastasis of Hepatocellular Carcinoma Presenting with Functional Tricuspid Valve Stenosis Accompanied with Hepatopulmonary Syndrome

Intracardiac metastasis of hepatocellular carcinoma with functional tricuspid valve stenosis is not common. Furthermore, hepatopulmonary syndrome associated with hepatocellular carcinoma is rarely encountered. We present a case of intracardiac metastasis of hepatocellular carcinoma presenting with functional tricuspid valve stenosis accompanied with hepatopulmonary syndrome.

Anomalous Origin of the Right Coronary Artery from the Left Anterior Descending Artery: An Extremely Rare Variety of Single Coronary Artery

Single anomalous coronary artery is a rare congenital anomaly of the coronary circulation. Right coronary artery (RCA) arising from the left anterior descending artery is an extermely rare variety of single coronary artery. We report a 68-year-old patient with a single coronary artery system, in whom the right coronary artery originated from the mid left anterior descending artery.

A Case of Liver Abscess Metastasizing to Prostate Resulting in Prostatic Abscess

Klebsiella pneumoniae(K. pneumoniae) infection has a tendency of abscess formation and it is known to be associated with diabetes mellitus. Metastatic infection was an important feature of K. pneumoniae liver abscess and bacteremia, metastatic prostate abscess was rare. We present a case of a 81-year-old man with K. pneumoniae liver abscess and metastatic prostate abscess, This patient was successfully treated with percutaneous abscess drainage of liver abscess and transurethral incisional drainage of prostate abscess.

A Case of Recurrent Paragonimiasis

Pulmonary paragonimiasis is a food-borne zoonosis, which is acquired from eating the raw or undercooked freshwater crabs or crayfish (crustaceans). It was highly endemic in Korea the late 1960's. However, human paragonimiasis is still sporadically occuring because of pupularization of Korean traditional crab dishes and is one of the lung disease which needs differential diagnosis. Recently, we experienced a case of pulmonary paragonimiasis in a 55 years man with dyspnea, dry cough and abdominal pain. The patient had hypereosinophilia and pulmonary infiltrates with pleural effusion, which did not improve on antibiotics. Diagnosis was confirmed by sputum with Paragonimus westermani ova, which was treated with praziquantel for two days at a daily dosage of 75 mg/kg. The patient was readmitted to the hospital 1 month following first treatment with recurrence of symptoms and he was cured by a second course of praziquantel.
