ABSTRACT

Background/Aims: The rates of Helicobacter pylori (H. pylori) eradication have declined with the use of proton pump inhibitor- amoxicillin-clarithromycin as the first-line triple therapy. On the other hand, several studies have suggested that high gastric pH levels could affect the H. pylori eradication rate by enhancing the efficacy of antimicrobials. This study compared the efficacy of seven-day high-dose esomeprazole-based triple therapy (7-HEAC) for first-line H. pylori eradication with the seven-day standard dose non-esomeprazole-based triple therapy (7-NEAC) to identify the risk factors related to eradication failure. Methods: This study included 223 patients who were diagnosed with a H. pylori infection and received 7-HEAC or 7-NEAC between June 2016 and January 2017. The H. pylori eradication rates, as well as demographic and clinical factors, were investigated retrospectively. H. pylori eradication was confirmed by a 13C-urea breath test or rapid urease test at least 4 weeks after the completion of therapy. Results: The eradication rates were 67.7% (105/155; 95% CI 59.5-74.8%) in the 7-NEAC group and 80.9% (55/68; 95% CI 69.9-89.8%) in the 7-HEAC group (p=0.045). The adverse event rates were 5.8% (9/155) in the 7-NEAC group and 7.4% (5/68) in the 7-HEAC group (p=0.661). Multivariate analysis revealed being female (OR 2.08; 95% CI 1.15-3.76) to be associated with the failure of H. pylori eradication therapy. Conclusions: The eradication rate of the 7-HEAC group was higher than that of the 7-NEAC group. Nevertheless, more effective first-line therapies may be necessary for H. pylori eradication in the near future.

ABSTRACT

BACKGROUND/AIMS: Minor disorders of peristalsis are esophageal motility disorders categorized by the Chicago Classification (CC), version 3.0, which was announced in 2014. This study evaluated the efficacy of anti-reflux therapy in patients with minor peristaltic disorders. METHODS: Patients with minor peristaltic disorders in accordance with CC v3.0 were included. We reviewed the medical records of patients with esophageal high-resolution manometry findings, and investigated the demographic and clinical information as well as the medical therapy. Thereafter, the response to treatment was assessed after at least 4 weeks of treatment. RESULTS: A total of 24 patients were identified as having minor disorders of peristalsis from January 2010 to December 2015. The mean follow-up period was 497 days, and there were 17 patients (70.8%) patients with ineffective esophageal motility. In terms of anti-reflux therapy, proton pump inhibitors (PPIs) with prokinetic agents and PPIs alone were prescribed in 19 patients (79.2%) and 5 patients (20.8%), respectively. When the rate of response to the treatment was assessed, the responders rate (complete+satisfactory [≥50%] responses) was 54.2% and the non-responders rate (partial [<50%]+refractory responses) was 45.8%. Patients in the responder group were younger than those in the non-responder group (p=0.020). Among them, 13 patients underwent 24-hour multichannel intraluminal impedance-pH, and 10 patients (76.9%) were pathologic gastroesophageal reflux. CONCLUSIONS: The majority of esophageal minor peristaltic disorders were accompanied by gastroesophageal reflux, and therefore, they might respond to acid inhibitor. Further well-designed, prospective studies are necessary to confirm the effect of anti-reflux therapy in these patients.

ABSTRACT

AIM: To investigate Helicobacter pylori (H. pylori) eradication rates using second-line bismuth-containing quadruple therapy and to identify predictors of eradication failure. METHODS: This study included 636 patients who failed first-line triple therapy and received 7 d of bismuth-containing quadruple therapy between January 2005 and December 2015. We retrospectively demonstrated H. pylori eradication rates 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 wk after the completion of bismuth-based quadruple therapy: proton pump inhibitor, metronidazole, bismuth, and tetracycline. RESULTS: The overall eradication rates by intention-to-treat analysis and per-protocol analysis were 73.9% (95%CI: 70.1%-77.4%) and 94.5% (95%CI: 92.4%-96.5%), respectively. Annual eradication rates from 2005 to 2015 were 100.0%, 92.9%, 100.0%, 100.0%, 100.0%, 97.4%, 100.0%, 93.8%, 84.4%, 98.9%, and 92.5%, respectively, by per-protocol analysis. A multivariate analysis showed that diabetes mellitus (OR = 3.99, 95%CI: 1.56-10.20, P = 0.004) was associated with H. pylori eradication therapy failure. CONCLUSION: The second-line bismuth-containing quadruple therapy for H. pylori infection is still effective in Korea, and diabetes mellitus is suggested to be a risk factor for eradication failure.

ABSTRACT

A subaortic membrane is an uncommon cause for left ventricular outflow tract obstruction. Hypertrophic cardiomyopathy with dynamic left ventricular outflow tract obstruction would mask the presence of the subaortic membrane on transthoracic echocardiography and cause a false diagnosis. We report a patient with subaortic stenosis due to flail subaortic membrane misdiagnosed as obstructive hypertrophic cardiomyopathy on transthoracic echocardiography, identified on transesophageal echocardiography and cardiac catheterization.

ABSTRACT

The anomalous origin of the right coronary artery (RCA) is a rare condition. Most RCA anomalies are usually found incidentally, but these findings have clinical significance because many patients, particularly young ones, present with sudden death, myocardial ischemia and syncope without other symptoms. We describe a case of a 39-year-old male patient that presented with effort chest pain and was diagnosed with anomalous RCA that originated from the ascending aorta with prior history of repairing ruptured sinus valsalva and ventricular septal defect. The anomalous origin of RCA was identified by multidetector computed tomography (MDCT). Successful percutaneous coronary intervention was performed guided by MDCT coronary images and intravascular ultrasound.

ABSTRACT

BACKGROUND AND OBJECTIVES: The comparison of long-term clinical effects between Sirolimus-eluting stent (SES) and Paclitaxel-eluting stents (PES) for treatment of acute myocardial infarction (AMI) remains unclear. Seeking to clarify this issue, we performed a retrospective analysis to evaluate four-year clinical outcomes of SES compared to PES treated AMI patients. SUBJECTS AND METHODS: From January 2004 to August 2006, all patients with acute ST-segment elevation myocardial infarction and acute non-ST segment elevation myocardial infarction who underwent percutaneous coronary intervention (PCI) by implantation of either SES or PES were enrolled. The occurrences of cardiac and non-cardiac deaths, recurrent infarction, target vessel revascularization (TVR) and stent thrombosis were analyzed. The composite end points of these major adverse cardiac events (MACE) were also analyzed. RESULTS: During the study period, a total of 668 AMI patients had visited, of which 522 patients (299 with SES and 223 with PES) were enrolled. During the four-year clinical follow-up, both groups showed similar occurrences of non-cardiac death (14.6±2.2% vs. 18.3±3.0%, p=0.26); cardiac death (6.8±1.52% vs. 11.2±2.6%, p=0.39); re-infarction (3.3±1.1% vs. 6.4±1.8%, p=0.31); and stent thrombosis (3.2±1.1% vs. 5.4±1.7%, p=0.53). However, occurrences of TVR {4.0±1.2% vs. 10.0±3.0%, hazard ratio (HR)=0.498, 95% confidence interval (CI)=0.257-0.967, p=0.039} and MACE (19.4±2.5% vs. 29.4±3.5%, HR=0.645, 95% CI=0.443-0.940, p=0.021) were significantly lower in the SES population. CONCLUSION: In AMI patients treated with either SES or PES implantation, the former had a significantly lower risk of TVR and MACE during four-year clinical follow-up. Rates of death, cardiac death or recurrent infarction, and stent thrombosis were similar.
