The multicenter real-world report of the efficacies of 14-day esomeprazole-based and rabeprazole-based high-dose dual therapy in first-line Helicobacter pylori eradication in Taiwan.

BACKGROUND: High-dose dual therapy (HDDT) using proton-pump inhibitors (PPI) and amoxicillin attracted attention for its simplicity and lower adverse event profile. Besides, vonoprazan is not available worldwide. This real-world study aims to compare the efficacy of esomeprazole-based and rabeprazole-based HDDT regimens and to identify clinical factors influencing outcomes. METHODS: A retrospective study enrolled 346 Helicobacter pylori-infected naïve patients from January 2016 to August 2023. Patients were assigned to either a 14-day esomeprazole-based HDDT (EA-14; esomeprazole 40 mg t.i.d. and amoxicillin 750 mg q.i.d. for 14 days, n = 173) or a 14-day rabeprazole-based HDDT (RA-14; rabeprazole 20 mg and amoxicillin 750 mg q.i.d. for 14 days, n = 173). RESULTS: Five patients from the EA-14 group and 10 from the RA-14 group were lost to follow-up, resulting in 168 and 163 patients for the per-protocol (PP) analysis, respectively. Eradication rates for the EA-14 and RA-14 groups were 90.2% and 80.9% (P = 0.014) in intention-to-treat (ITT) analysis; and 92.9% and 85.9% (P = 0.039) in PP analysis. Adverse event rates were similar between the two groups (11.9% vs 11.7%, P = 0.944). In multiple logistic regression analysis, age≧60 was associated with eradication failure (P = 0.046) and a trend of significance for smoking (P = 0.060) in the EA-14 group but not in the RA-14 group. A trend of significance was also observed for eradication regimens (EA-14 vs RA-14) (P = 0.071). The antibiotic resistance rates were amoxicillin (2.3%), clarithromycin (14.7%), metronidazole (40.3%), and dual resistance to clarithromycin and metronidazole (7.0%). CONCLUSIONS: Esomeprazole-based HDDT achieved over 90% eradication rates but rabeprazole-based HDDT, which failed.

The Clinical Presentations of Liver Abscess Development After Endoscopic Retrograde Cholangiopancreatography with Choledocholithiasis: A 17-Year Follow-Up.

Background: Endoscopic Retrograde Cholangiopancreatography (ERCP), used for choledocholithiasis treatment, carries a risk of pyogenic liver abscess (PLA) due to communication between the biliary system and bowel contents. However, limited data exists on this issue. This study aims to identify the risk factors pertaining to liver abscesses following ERCP lithotomy. Methods: We conducted a retrospective case series across multiple centers to evaluate patients who developed PLA after ERCP for choledocholithiasis. Data was obtained from the Chung Gung Research Database (January 2001 to December 2018). Out of 220 enrolled patients, 195 were categorized in the endoscopic sphincterotomy (ES) group, while 25 were in the non-ES group for further analysis. Results: The non-ES group had significantly higher total bilirubin levels compared to the ES group (4.3 ± 5.8 vs 1.9 ± 2.0, p<0.001). Abscess size, location, and distribution (single or multiple) were similar between the two groups. The most common pathogens were Klebsiella pneumoniae and Escherichia coli. Pseudomonas infection was significantly less prevalent in the ES group compared to the non-ES group (3.6% vs 16.7%, p=0.007). Patients with concurrent malignancies (HR: 9.529, 95% CI: 2.667-34.048, p=0.001), elevated total bilirubin levels (HR: 1.246, 95% CI: 1.062-1.461, p=0.007), multiple abscess lesions (HR: 5.146, 95% CI: 1.777-14.903, p=0.003), and growth of enterococcus pathogens (HR: 4.518, 95% CI: 1.290-15.823, p=0.001) faced a significantly higher risk of in-hospital mortality. Conclusion: PLA incidence was higher in the ES group compared to the non-ES group following ERCP for choledocholithiasis. Attention should be given to significant risk factors, including concurrent malignancies, elevated total bilirubin levels, multiple abscess lesions, and growth of enterococcus pathogens, to reduce in-hospital mortality.

Correlation between Psychosomatic Assessment, Heart Rate Variability, and Refractory GERD: A Prospective Study in Patients with Acid Reflux Esophagitis.

BACKGROUND: Gastroesophageal reflux disease (GERD) affects a significant proportion of individuals, with life stress being a contributing factor. This study aimed to investigate the correlation between psychosomatic evaluations, heart rate variability (HRV), and GERD in a cohort of individuals. Additionally, the study aimed to analyze the sequencing changes following proton pump inhibitor (PPI) treatment and identify predictive factors associated with refractory GERD. METHODS: A prospective cohort of 105 individuals with reflux esophagitis and a control group of 50 participants without acid reflux symptoms were enrolled. Psychosomatic evaluations, including GERDQ, GERDQLQ, RSI, BAI, BDI, and SSS-8, were assessed at baseline and during treatment. HRV parameters were also evaluated. Multivariate analysis was used to identify predictive factors for refractory GERD. PPIs were administered regularly for the initial 2 months and then used on-demand. Refractory GERD was defined as less than 50% improvement in symptom relief or GERDQLQ score ≥ 20 after 8 weeks of PPI treatment. RESULTS: The GERD group had higher scores in all psychosomatic evaluations compared to the control group (all p-values < 0.001). There were no significant changes in any parameters of HRV before and after treatment in the GERD group. Strong and consistent correlations were observed between GERD symptoms and psychological scores (BAI, BDI, and SSS-8) across all time points (W0, W4, and W8). Sequential reductions in GERD symptom scores and psychosomatic evaluations were observed during the initial eight weeks of treatment. Higher GERDQ (≥10) and SSS-8 (≥12) scores were predictive of refractory GERD (p = 0.004 and p = 0.009, respectively). CONCLUSIONS: This study emphasizes the importance of considering physiological and psychological factors in the management of GERD. Psychosomatic evaluations provide valuable insights for assessing and treating GERD patients. Integrating stress management and comprehensive assessments into personalized treatment strategies is crucial.

The Efficacy and Safety of 14-day Rabeprazole Plus Amoxicillin High Dose Dual Therapy by Comparing to 14-day Rabeprazole-Containing Hybrid Therapy for the Naïve Helicobacter pylori Infection in Taiwan: A Randomized Controlled Trial.

INTRODUCTION: High-dose dual therapy (HDDT) can attain acceptable eradication rates provided that the optimal doses, timing and treatment duration are applied. The existing evidence still shows inconsistent reports (< 90%) on HDDT therapy except in some Asian countries. We aimed to assess and compare the efficacy of 14-day HDDT by comparing it to 14-day rabeprazole-containing hybrid therapy (HT) and to investigate the host and bacterial factors predicting the treatment outcomes of eradication therapies. METHODS: In this open-label, randomized controlled trial, we recruited 243 naïve Helicobacter pylori-infected patients from September 1, 2018, to November 30, 2021. They were randomly allocated (1:1) to the HDDT group (rabeprazole 20 mg and amoxicillin 750 mg q.i.d for 14 days, n = 122) and the HT group (rabeprazole 20 mg and amoxicillin 1 g b.i.d. for 7 days, followed by rabeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg b.i.d. for 7 days, n = 121). Twelve patients were absent during follow-up in the HDDT group and 4 in the HT group, resulting in 110 for the HDDT group and 117 for HT group in the per protocol (PP) study. The outcome was determined by urea breath tests 8 weeks later. RESULTS: The eradication rates for the HDDT and HT groups were 77.0% (95% confidence interval [CI]: 68.5% to 84.1%) and 94.2% (95% CI: 88.4% to 97.6%) (P < 0.001) in intention-to-treat analysis; 85.5% (95% CI: 77.5% to 91.5%) and 97.4% [95% CI: 92.6% to 99.5%] (P = 0.001) in per protocol analysis. The adverse event rates were 7.3% in the HDDT group and 14.5% in the HT group (P = 0.081). The habit of coffee drinking was the dependent factor for eradication failure in the HDDT group (88.2% vs. 68.8%, P = 0.040), but had no influence in the HT group (97.9% versus 95.0%, P = 0.449) in the univariate analysis. CONCLUSION: This study demonstrated that 14-day rabeprazole-containing HDDT did not achieve > 90% eradication rates for first-line H. pylori eradication as 14-day rabeprazole-containing HT did. HDDT is a potentially beneficial combination, which involves only two drugs with mild adverse effects; more precise studies are urged to find answers regarding these failures. This clinical trial was registered retrospectively on 28 November, 2021, as ClinicalTrials.gov identifier: NCT05152004.

Increased Risk of Pyogenic Liver Abscess after Endoscopic Sphincterotomy for Treatment of Choledocholithiasis.

BACKGROUND AND AIM: Endoscopic sphincterotomy (ES) abolished the barrier between the hepatobiliary system and duodenum and might be at risk of pyogenic liver abscess (PLA). We aimed to identify the association factors of PLA in patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) procedures for treatment of choledocholithiasis. METHODS: This study was based on the Chung Gung Research Database (CGRD) between January 1, 2001 and December 31, 2018. Those who had an International Classification of Diseases, Ninth and Tenth Revision (ICD9 and ICD10) codes of choledocholithiasis and received ERCP were enrolled. After strict exclusions, 11,697 patients were further divided into the endoscopic sphincterotomy (ES) group (n=7,111) and other ERCP group (n=4,586) for analysis. RESULTS: Patients receiving ES had significantly higher rates of PLA than those of the other ERCP group (5-year cumulative incidence 2.4% versus 1.7%; 10-year cumulative incidence 3.9% versus 3.2%, log-rank p=0.0177). Aging, male gender, surgery for hepato-pancreato-biliary system and hepatobiliary malignancy were significant association factors of PLA. On multivariate analysis, the ES increased the risk of PLA (adjusted hazard ratio [aHR]=1.49; 95% CI=1.12-1.98; p=0.0058) but decreased the risks for acute pancreatitis (aHR=0.72; 95% CI=0.60-0.85; p=0.0002) and cholangitis (aHR= 0.91; 95% CI=0.84-0.99; p=0.0259). There was no significant difference about recurrent choledocholithiasis between groups. CONCLUSION: This study demonstrated a significant risk of PLA after patients receiving ES compared with the other ERCP group. We should also carefully monitor the association factors of PLA after ERCP treatment of choledocholithiasis including aging, male gender, surgery for the hepato-pancreato-biliary system and hepatobiliary malignancy.

Eradication Rates for Esomeprazole and Lansoprazole-Based 7-Day Non-Bismuth Concomitant Quadruple Therapy for First-Line Anti-Helicobacter pylori Treatment in Real World Clinical Practice.

PURPOSE: Non-bismuth concomitant quadruple therapy is commonly administered in Taiwan, achieving an acceptable efficacy as a first-line anti-Helicobacter pylori treatment. This study compared the eradication rates between esomeprazole- and lansoprazole-based non-bismuth concomitant quadruple therapy for first-line anti-H. pylori treatment. PATIENTS AND METHODS: This study included 206 H. pylori-infected naïve patients between July 2016 and February 2019. The patients were prescribed with either a 7-day non-bismuth containing quadruple therapy (esomeprazole, 40 mg twice daily; amoxicillin, 1 g twice daily; and metronidazole, 500 mg twice daily; and clarithromycin, 500 mg twice daily for 7 days [EACM group]; lansoprazole, 30 mg twice daily; amoxicillin, 1 g twice daily; metronidazole, 500 mg twice daily; and clarithromycin, 500 mg twice daily [LACM group]). Then, the patients were asked to perform urea breath tests 8 weeks later. RESULTS: The eradication rates in the EACM group were 86.1% (95% confidence interval [CI], 77.8%-92.2%) and 90.6% (95% CI, 82.9%-95.6%) in the intention-to-treat (ITT) and the per-protocol (PP) analyses, respectively. Moreover, the eradication rates in the LACM group were 90.1% (95% CI, 82.6%-95.2%) and 92.6% (95% CI, 85.5%-96.9%) in the ITT and the PP analyses, respectively. Consequently, the LACM group exhibited more diarrhea patients than the EACM group (7.1% versus 1.0%, p = 0.029), but all symptoms were mild. Univariate analysis in this study showed that metronidazole-resistant strains were the clinical factor affecting the eradications (95.3% versus 78.9%, p = 0.044). Moreover, a trend was observed in dual clarithromycin- and metronidazole-resistant strains (91.5% versus 66.7%, p = 0.155). CONCLUSION: The eradication rates between esomeprazole and lansoprazole-based non-bismuth concomitant quadruple therapy for first-line H. pylori treatment were similar in this study. Both could achieve a > 90% report card in the PP analysis.

The efficacies of non-bismuth containing quadruple therapies in the treatment of first-line anti-Helicobacter pylori across 4-year time interval with changing antibiotics resistance.

BACKGROUND: Non-bismuth containing quadruple therapy (concomitant therapy) is an alternative treatment for Helicobacter pylori (H. pylori) eradication with increasing clarithromycin-resistant strains over times. This study compared the efficacies of non-bismuth containing quadruple therapy (concomitant therapy) in the treatment of first-line anti-Helicobacter Pylori between two time intervals (January 2013 to June 2014 and June 2016 to December 2017). METHODS: H. pylori-infected patients were recruited in the intention-to-treat (ITT analysis) and divided into EACM-A group (enrolled from January 2013 to June 2014, N = 98) and EACM-B group (enrolled from June 2016 to December 2017, N = 99). Patients were prescribed with 7-day esomeprazole 40 mg bid., clarithromycin 500 mg bid., amoxicillin 1 g bid. and metronidazole 500 mg bid. Ninety patients and 93 patients were analyzed in the per protocol (PP) analysis (8 and 6 patients lost follow-up in each group). Urea breath tests were performed 4-8 weeks thereafter. RESULTS: The eradication rates for EACM-A and EACM-B groups were 87.8% (95% confidence interval [CI] = 79.7%-93.5%) and 84.8% (95% CI = 76.2%-91.2%) (p = 0.55) in intention-to-treat (ITT) analysis; 95.6% (95% CI = 89.1%-98.8%) and 90.3% (95% CI = 82.4%-95.5%) (p = 0.17) in per protocol (PP) analysis. The adverse event rates were 16.7% vs. 10.8% in the 2 groups (p = 0. 0.24). The antibiotic resistance rates between the 2 groups were amoxicillin (0%), tetracycline (0%); clarithromycin (11.8% vs. 17.8%, p = 0.46); metronidazole (32.4% vs. 33.3%, p = 0.93) and levofloxacin (14.7% vs. 37.8%, p = 0.02). CONCLUSION: The success rate of 7-days concomitant therapy encountered an approximately 5% decrease across 4-year time interval (2013-2017) with the changes of clarithromycin resistance from 11.8% to 17.8% in Taiwan.

Risks of adverse events for users of proton-pump inhibitors plus aspirin or clopidogrel in patients with aspirin-related ulcer bleeding.

BACKGROUND AND AIM: Clopidogrel is widely prescribed for patients with of aspirin-related upper gastrointestinal bleeding (UGIB) history. This study aimed to compare the risk of a major adverse cardiovascular event (MACE), UGIB, and mortality between aspirin and clopidogrel in patients at risk of bleeding. METHODS: We analyzed adult patients at high risk of UGIB following aspirin-related bleeding for secondary MACE prevention between 2000 and 2012. Secondary prevention was for those patients who had ever been hospitalized for cardiovascular disease and reused aspirin or changed to clopidogrel after discharge. Study endpoints were recurrence of MACE, UGIB, and death in 90 days of follow-up. The associations between study outcomes and the use of clopidogrel (vs aspirin) were analyzed. RESULTS: Among 947 eligible patients, 653 reused aspirin (in combination with a proton-pump inhibitor), and 294 were treated with clopidogrel (in combination with a proton-pump inhibitor) after discharge for UGIB. Compared with aspirin treatment, clopidogrel showed an increased risk of MACE (adjusted hazard ratio [aHR] 1.65; 95% confidence interval [CI] 0.87-3.12) and UGIB (aHR 1.25; 95% CI 0.66-2.36), but without statistical significance in 90 days' follow-up. Clopidogrel use was associated with greater than four times the risk of any cause of mortality (aHR 4.84; 95% CI 1.59-14.75), but the significance did not hold in propensity score-matched cohort analysis (P = 0.06). CONCLUSIONS: A nonsignificant difference between clopidogrel and aspirin for short-term MACE prevention as well as UGIB recurrence was found in the present study. Further research to assess 90-day mortality would assist clinical decision making.

The impact of aspirin on Klebsiella pneumoniae liver abscess in diabetic patients.

In this study, we aimed to investigate the impact of aspirin on the risk of pyogenic liver abscess caused by Klebsiella pneumoniae (KP-PLA) and invasive KP-PLA syndrome (IKPS) in diabetic patients. Diabetic patients who were propensity-score matched were retrospectively included from hospital-based database. Kaplan-Meier approach with a log-rank test was used to compare the cumulative incidences of KP-PLA including IKPS between aspirin users and non-users. Totally, 63,500 patients were analyzed after propensity-score matching (1:1). Compared with that of non-users, the incidence of KP-PLA was significantly reduced in aspirin users (0.31% vs. 0.50%, p < 0.01), but not for that of IKPS (0.02% vs. 0.03%, p = 0.29). Patients taking aspirin for ≥ 90 days had a significantly lower risk for KP-PLA (hazard ratio, 0.67; 95%CI, 0.50-0.90). Females, taking clopidogrel or metformin for ≥ 90 days, and taking H2-blockers or proton pump inhibitors (PPIs) for ≥ 5 days were also associated with a lower risk of KP-PLA. However, cholangitis and a glycated hemoglobin ≥ 8.5% were associated with an increased risk of KP-PLA.

Incidence and risk factors of colonoscopic post-polypectomy bleeding and perforation in patients with end-stage renal disease.

BACKGROUND AND AIMS: Colonoscopic polypectomy in end-stage renal disease (ESRD) patients are at risks of post-polypectomy bleeding and perforation, but evidences are limited. This study aimed to determine the incident polypectomy complications among ESRD patients. METHODS: In the nationwide ESRD cohort, a propensity score matched case-control study design was conducted to assess risk associated with post-polypectomy bleeding and perforation using the Taiwanese National Health Insurance Research Database from 1997 to 2013 for adults aged 40 years and older; 7011 ESRD and 19 118 non-ESRD patients met the study criteria. A total of 5302 patients in each group were matched for further analyses. The primary endpoint was post-polypectomy bleeding or bowel perforation in 30 days. The secondary endpoint was mortality and length of hospital stay for the bleeding complications requiring hospitalization. RESULTS: Overall incidences of post-polypectomy bleeding or perforation in patients with ESRD was higher than the non-ESRD group (5.83% vs 1.78%, P < 0.0001) in the matched cohort. High risk of adverse outcomes was associated with ESRD (adjusted odds ratio [aOR], 2.38, 95% confidence interval [CI], 1.85-3.05), female patient (aOR, 1.7, 95% CI, 1.37-2.11), history of acute myocardial infarction (aOR, 1.91, 95% CI, 1.1-3.32), liver disease (aOR, 1.79, 95% CI, 1.37-2.34), diabetes (aOR, 1.45, 95% CI, 1.16-1.82), cancer (aOR, 1.4, 95% CI, 1.09-1.81), inpatient setting (aOR, 13.19, 95% CI, 9.73-17.88), and prior use of clopidogrel (aOR, 1.61, 95% CI, 1.03-2.52) and warfarin (aOR, 2.03, 95% CI, 1.21-3.41). CONCLUSIONS: End-stage renal disease was associated with approximately twofold higher risk of colonoscopic post-polypectomy bleeding or perforation and should be cautiously performed in this special population cohort.

The role of antibiotics in upper gastrointestinal bleeding among cirrhotic patients without major complications after endoscopic hemostasis.

BACKGROUND AND AIM: Antibiotic prophylaxis should be instituted for cirrhotic patients with upper gastrointestinal bleeding (UGIB), but the benefit on compensated patients remains undetermined. We aimed to compare the clinical outcomes between cirrhotic patients without major complications with UGIB with and without antibiotic prophylaxis. METHODS: We conducted this population-based cohort study by using Taiwanese Longitudinal Health Insurance Database 2000 (LHID2000, between 1997 to 2013), aged 18 years or older with a hospital discharge diagnosis of cirrhosis (n = 64,506), UGIB (n = 7,784), and endoscopic therapy (n = 2,292). After strict exclusions, 1205 patients were enrolled and were divided into antibiotic exposure (n = 558) and non-exposure (n = 647) groups. The outcomes were rebleeding and mortality. RESULTS: After completing the analysis adjusted by death, the rebleeding rates within 4 weeks were significantly lower in patients with antibiotic prophylaxis (3.05% versus 6.03%, P = 0.0142) and those with endoscopic therapy (0.72% vs 3.09%, P = 0.0033) but not significant after 3 months and onwards. Male patients aged > 55, high CCI score â‰§ 4, and UGIB of variceal etiologies were benefited from rebleeding. The use of antibiotics did not significantly impact 6-week mortality (adjusted hazard ratio: 1.07, 95%CI: 0.41~2.75; P = 0.8943). Old age, multiple comorbidities, and UGIB of variceal etiologies were risk factors of all-cause mortality. CONCLUSIONS: The current study suggested that cirrhotic patients without major complications who suffered from UGIB were benefited by the use of antibiotics to prevent rebleeding within 4 weeks after endoscopic treatment of UGIB especially for those with age > 55, high CCI score â‰§ 4, and UGIB of variceal etiologies.

A comparison between dexlansoprazole modified release-based and lansoprazole-based nonbismuth quadruple (concomitant) therapy for first-line Helicobacter pylori eradication: a prospective randomized trial.

PURPOSE: Steadily maintaining high intra-gastric PH is the major factor for successful Helicobacter pylori (H.pylori) eradication. It is important to search for a stronger PPI. Dexlansoprazole MR is a dual delayed release formulation PPI taken once daily which is capable of maintaining longer duration of high intra-gastric PH. It is very effective in treating gastroesophageal disease but reports on H, pylori eradication is very rare. This study sought to compare dexlansoprazole MR-based concomitant treatment and lansoprazole-based concomitant treatment in H. pylori infection and to investigate the factors that affect the eradication rates. METHODS: Two hundred two participants with H. pylori infection were included and randomly assigned to seven days of dexlansoprazole MR-based concomitant therapy (dexlansoprazole MR 60 mg once daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily and metronidazole 500 mg twice daily; DACM group) or a seven days of lansoprazole-based concomitant therapy (lansoprazole 30 mg twice daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily, and metronidazole 500 mg twice daily; LACM group). The participants were asked to perform urea breath tests eight weeks later. RESULTS: The eradication rates in the DACM group were 86.1% [95% confidence interval (CI): 77.8%-92.2%] in the ITT analysis and 90.6% (95% CI: 82.9%-95.6%) in the PP analysis, respectively, as compared with 90.1% (95% CI: 82.6%-95.2%) and 92.6% (95% CI: 85.5%-96.9%) (p=0.384 and p=0.572, respectively) in the LACM group for the same analyses. The adverse event rates were 11.5% in the DACM group and 10.2% in the LACM group (p=0.779). CONCLUSION: As a first-line H. pylori treatment regimen, dexlansoprazole MR-based concomitant therapy attained a successful eradication rate of 90%, which was non inferior to that of lansoprazole-based concomitant treatment.

Risk of Recurrent Peptic Ulcer Disease in Patients Receiving Cumulative Defined Daily Dose of Nonsteroidal Anti-Inflammatory Drugs.

The purpose of this population-based case-control study was to clarify the impact of cumulative dosage of nonsteroidal anti-inflammatory drugs (NSAIDs) on recurrent peptic ulcers among chronic users after Helicobacter pylori (H. pylori) eradication. We analyzed data of 203,407 adult peptic ulcer disease (PUD) patients from the National Health Insurance Research Database in Taiwan entered between 1997 and 2013. After matching for age/gender frequencies and the length of follow-up time in a ratio of 1:1, the matched case-control groups comprised 1150 patients with recurrent PUD and 1150 patients without recurrent PUD within 3 years of follow-up. More recurrent PUDs occurred in NSAID users than in the control group (75.30% versus 69.74%; p = 0.0028). Independent risk factors for recurrent PUD included patients using NSAIDs (adjusted OR (aOR): 1.34, p = 0.0040), H. pylori eradication (aOR: 2.73; p < 0.0001), concomitant H2 receptor antagonist (aOR: 1.85; p < 0.0001) and anti-coagulant (aOR: 4.21; p = 0.0242) use. Importantly, in the initial subgroup analysis, the risk ratio of recurrent PUD did not increase in NSAID users after H. pylori eradication compared with that in non-users (p = 0.8490) but a higher risk for recurrent PUD with the increased doses of NSAIDs without H. pylori eradication therapy (aOR: 1.24, p = 0.0424; aOR: 1.47, p = 0.0074; and aOR: 1.64, p = 0.0152 in the groups of ≤28, 29-83, and ≥84 cumulative defined daily doses, respectively). The current study suggested that H. pylori eradication therapy could decrease the risk of recurrent PUD among patients with high cumulative doses of NSAIDs.

First-line Helicobacter pylori eradication rates are significantly lower in patients with than those without type 2 diabetes mellitus.

Purpose: To assess the difference of the first-line therapy for Helicobacter pylori in patients with or without type 2 diabetes (DM) and to investigate the clinical factors influencing treatment outcomes. Patients and methods: In total, 719 patients with H. pylori infection were treated with 7-day standard first-line triple therapy, of whom 182 did and 537 did not have DM. Propensity score matched at a 1:2 ratio - for age, sex and body mass index was performed for the two groups, yielding a DM group with 147 patients and a non-DM group with 249 matched controls for analysis. Urea breath test was performed 6-8 weeks after treatment. Clinical and laboratory parameters were collected for identifying factors associated with failed eradication. Results: H. Pylori was eradicated in 74.1% (95% confidence interval [CI] =66.2-81.0) of the DM group and 85.3% (95% CI =80.8-89.4) of the non-DM group (p=0.005). Of 51 gastric biopsy samples cultured for H. pylori, 41 were positive. In the DM group, the rates of resistance to amoxicillin, clarithromycin, levofloxacin, and tetracycline were 0%, 50.0%, 50.0% and 0%, respectively. In the non-DM group, the comparable proportions were 2.9%, 17.1%, 22.9%, and 0%, respectively. Univariate analysis revealed that DM (Odds ratio [OR], 1.771, 95% CI, 1.167-2.668, p=0.006), clarithromycin resistance (OR, 15.273; 95% CI, 1.687-138.269; p=0.015), and amoxicillin resistance (OR, 4.672; 95% CI, 2.431-8.979; p<0.001) were independently associated with failure to eradicate H. pylori. Multivariate analysis showed that clarithromycin resistance was the major factor independently associated with failure of eradication (OR, 25.472; 95% CI, 1.549-418.956; p=0.023). Conclusions: First-line H. pylori eradication rates in patients with DM were significantly lower than in those without DM, although neither group achieved >90% eradication.

Clinical efficacy of 60-mg dexlansoprazole and 40-mg esomeprazole after 24 weeks for the on-demand treatment of gastroesophageal reflux disease grades A and B: a prospective randomized trial.

Purpose: Research comparing the clinical efficacy of dexlansoprazole and esomeprazole has been limited. This study aims to compare the clinical efficacy of single doses of dexlansoprazole (modified-release 60 mg) and esomeprazole (40 mg) after 24-week follow-up in patients with mild erosive esophagitis. Methods: We enrolled 86 adult GERD subjects, randomized in a 1:1 ratio to two sequence groups defining the order in which they received single doses of dexlansoprazole (n=43) and esomeprazole (n=43) for 8 weeks as initial treatment. Patients displaying complete symptom resolution (CSR) by the end of initial treatment (8 weeks) were switched to on-demand therapy until the end of 24 weeks. Follow-up endoscopy was performed either at the end of 24 weeks or when severe reflux symptoms occurred. Five patients were lost to follow-up, leaving 81 patients (dexlansoprazole, n=41; esomeprazole, n=40) in the per-protocol analysis. Results: The GERDQ scores at 4-, 8-, 12-, 16-, 20-, and 24-week posttreatment were less than the baseline score. The CSR, rate of symptom relapse, days to symptom resolution, sustained healing rate of erosive esophagitis, treatment failure rate, and the number of tablets taken in 24 weeks were similar in both groups. The esomeprazole group had more days with reflux symptoms than the dexlansoprazole group (37.3±37.8 vs 53.9±54.2; P=0.008). In the dexlansoprazole group, patients exhibited persistent improvement in the GERDQ score during the on-demand period (week 8 vs week 24; P<0.001) but not in the esomeprazole group (week 8 vs week 24; P=0.846). Conclusions: This study suggests that the symptom relief effect for GERD after 24 weeks was similar for dexlansoprazole and esomeprazole. Dexlansoprazole exhibited fewer days with reflux symptoms in the 24-week study period, with better persistent improvement in the GERDQ score in the on-demand period.

A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy regimen achieves a high eradication rate as first-line anti-Helicobacter pylori treatment in Taiwan: a prospective randomized trial.

BACKGROUND: The first-line eradication rate of standard triple therapy for Helicobacter pylori infection has declined to <80%, and alternative therapies with >90% success rates are needed. Inconsistent eradication rates were reported for proton pump inhibitor- and amoxicillin-containing high-dose dual therapy. OBJECTIVES: We performed a prospective, randomized controlled study to assess the efficacy of esomeprazole- and amoxicillin-containing high-dose dual therapy and investigated the influencing clinical factors. PATIENTS AND METHODS: We recruited 240/278 eligible H. pylori-infected patients after exclusion. They were randomly assigned to 14 day high-dose dual therapy (esomeprazole 40 mg three times daily and amoxicillin 750 mg four times daily for 14 days; EA group) or 7 day non-bismuth quadruple therapy (esomeprazole 40 mg twice daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily and metronidazole 500 mg twice daily for 7 days; EACM group). Urea breath tests were followed up 8 weeks later. RESULTS: The eradication rates for the EA and EACM groups were 91.7% (95% CI = 85.3%-96.0%) and 86.7% (95% CI = 79.3%-92.2%) (P = 0.21) in ITT analysis; and 95.7% (95% CI = 90.2%-98.6%) and 92.0% (95% CI = 85.4%-96.3%) (P = 0.26) in PP analysis. The adverse event rates were 9.6% versus 23.0% in the two groups (P = 0.01). The H. pylori culture positivity rate was 91.8%. The antibiotic resistance rates were amoxicillin, 0%; clarithromycin, 14.6%; and metronidazole, 33.7%. CONCLUSIONS: A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy achieves a high eradication rate as first-line anti-H. pylori therapy, comparable to that with 7 day non-bismuth quadruple therapy but with fewer adverse events.

The Role of Non-Selective ß-Blockers in Compensated Cirrhotic Patients without Major Complications.

Background and Objectives: Non-selective ß-blockers (NSBB) could prevent decompensation and hepatocellular carcinoma (HCC) in cirrhotic patients with clinically significant portal hypertension (CSPH), but remained uncertain for compensated cirrhotic patients without major complications. We aimed to compare the clinical outcomes between propranolol users and non-users of a CC group without major complications. Material and Methods: We conducted this population-based cohort study by using the Taiwanese Longitudinal Health Insurance Database 2000. Propranolol users (classified as cumulative defined daily dose (cDDD)) and non-PPL users were matched with a 1:1 propensity score in both cohorts. Results: This study comprised 6896 propranolol users and 6896 non-propranolol users. There was no significant impact on the development of spontaneous bacterial peritonitis between the two groups (aHR: 1.24, 95% confidence interval (CI): 0.88~1.75; p = 0.2111). Male gender, aged condition, and non-liver related diseases (peripheral vascular disease, cerebrovascular disease, dementia, pulmonary disease, and renal disease) were the independent risk factors of mortality. PPL users had significantly lower incidence of HCC development than non-users (aHR: 0.81, p = 0.0580; aHR: 0.80, p = 0.1588; and aHR: 0.49, p < 0.0001 in the groups of 1-28, 29-90, and >90 cDDD, respectively). Conclusion: The current study suggested that high cumulative doses of propranolol could decrease the risk of hepatocellular carcinoma among compensated cirrhotic patients without major complications. Further large-scale prospective studies are still required to confirm the findings in this study. Results: It remained uncertain whether non-selective ß-blockers (NSBB) could prevent decompensation and hepatocellular carcinoma (HCC) in compensatory cirrhotic patients without major complications. This study aimed to compare the clinical outcomes between propranolol users and non-users of the CC group without major complications.

Efficacy of a 14-day quadruple-therapy regimen for third-line Helicobacter pylori eradication.

PURPOSE: To assess the efficacy of amoxicillin, tetracycline, high-dose metronidazole, and a proton-pump inhibitor for third-line Helicobacter pylori eradication. METHODS: We enrolled 70 consecutive patients who had registered, failed to respond to two rounds of H. pylori eradication, and undergone endoscopy for H. pylori culture. Seven patients were lost to follow-up. Patients were treated according to the results of antibiotic-susceptibility testing reports (cultured group, n=39). Those who failed the H. pylori culture were prescribed 14-day quadruple therapy containing esomeprazole 40 mg twice daily, amoxicillin 1 g twice daily, tetracycline 500 mg four times daily, and metronidazole 500 mg three times daily (empirical group, n=24). A follow-up urea breath test was performed 8 weeks later. RESULTS: Antibiotic-resistance rates were 79.5% (clarithromycin), 94.9% (levofloxacin), 66.7% (metronidazole), 2.6% (amoxicillin), and 0 (tetracycline). Eradication rates attained by the cultured and empirical group were 89.7% (95% CI 72.7%-97.1%) and 58.3% (95% CI 36.6%-77.9%) in per-protocol analysis (P=0.004) and 81.4% (95% CI 66.6%-91.6%) and 51.8% (95% CI 31.9%-71.3%) in intention-to-treat analysis (P=0.014), respectively. Culture-guided therapy was the only clinical factor influencing the efficacy of H. pylori eradication (OR 0.16, 95% CI 0.04-0.60; P=0.006). Despite the high metronidazole-resistance rate (66.7%) after two treatment failures, the eradication rate in patients with this condition was 84%. CONCLUSION: Empirical 14-day modified quadruple therapy is not acceptable as an alternative third-line rescue H. pylori treatment. The success rate of third-line susceptibility-guided treatment was near 90%. This report is valuable as a reminder to medical practitioners that rather than a try-and-see approach, susceptibility-guided therapy should always be considered whenever possible for patients who have undergone several treatment failures.

Treatment and Cost of Hepatocellular Carcinoma: A Population-Based Cohort Study in Taiwan.

Hepatitis B virus vaccination and antiviral therapies reduce the risk of hepatocellular carcinoma (HCC). However, the lifetime healthcare expenditure involved in caring for HCC patients remains unclear. We examined the use and direct costs of healthcare services for a cohort of HCC patients to the healthcare system using Taiwan national health insurance program research database between 1997 and 2012. Total medical cost for all reimbursed patient encounters, including hospitalizations and outpatient care was cumulated from HCC onset to the end of follow-up or death. The mean follow-up time was 2.7 years (standard deviation, SD = 3.3) for the entire HCC cohort. Insurance payments of approximately US$92 million were made to 5522 HCC patients, with a mean cost of US$16,711 per patient (21,350). On average, the total cost per patient per month was US$2143 (5184); it was 50% higher for advanced cirrhosis patients at the baseline but 23% lower for mild-to-moderate cirrhotic patients. In the two-part regression, patients' underlying comorbid conditions, liver transplants, hepatectomy, and transarterial chemoembolization were associated with increased total cost, with liver transplants having the greatest impact over time. Hepatocellular carcinoma imposes substantial burden on the healthcare system. Real-world evidence on treatment and cost outcomes highlighted the needs to expand effective screening strategies and to optimize healthcare delivery to meet HCC patients' clinical needs.

Multiple bacterial infections increase the risk of hepatic encephalopathy in patients with cirrhosis.

OBJECTIVE: Patients with liver cirrhosis (LC) are at increased risk for bacterial infections. It is not fully understood how exposure to infections induces further development of hepatic encephalopathy (HE). This study estimated risks of infection associated with HE among patients with LC. METHODS: A nested case-control study of 14,428 adult patients with LC was performed using the population-based Longitudinal Health Insurance Database 2000 in Taiwan. Cases were cirrhotic patients who developed HE during follow-up. Controls were matched to each case by age at LC diagnosis (±2 years), sex, Charlson Comorbid index score, year of LC, and follow-up time with a 1:1 ratio. A multivariate logistic regression model was used to determine and compare the odds of developing HE based on exposure to various risk factors, including site of infection, cirrhosis-related complications, Helicobacter pylori eradication therapy, and peptic ulcer bleeding. Patient survival was evaluated using the time-dependent Cox regression model. RESULTS: Cirrhotic patients with HE (n = 714) and without HE (n = 714) were matched to compare risks. Infections and more frequent yearly infections were significantly associated with increased risk of HE. Independent predictors of HE included spontaneous bacterial peritonitis (aOR, 5.13; 95% CI, 3.03-8.69), sepsis (aOR, 2.54; 95% CI, 1.82--3.53), and biliary tract infection (aOR, 2.03; 95% CI, 1.2-3.46), controlling for confounders. CONCLUSION: Frequent infections are associated with increased risk of HE in cirrhotic patients. More frequent exposure to infection increases the risk of HE and mortality rates. Appropriate prevention of infection and the use of antibiotics for cirrhotic patients at risk for HE are needed.
