The study aimed to compare the efficacies and safety of 14-day hybrid therapy, 14-day high-dose dual therapy, and 10-day bismuth quadruple therapy in the first-line treatment of Helicobacter pylori infections. In this multicenter, open-label, randomized trial, we recruited adult H. pylori -infected patients from 9 centers in Taiwan. Subjects were randomly assigned (1:1:1) to 14-day hybrid therapy, 14-day high-dose dual therapy, or 10-day bismuth quadruple therapy. Eradication status was determined by the 13 C-urea breath test. The primary outcome was the eradication rate of H. pylori assessed in the intention-to-treat population. Between August 1, 2018, and December 2021, 918 patients were randomly assigned in this study. The intention-to-treat eradication rates were 91.5% (280/306; 95% confidence interval [CI] 88.4%-94.6%) for 14-day hybrid therapy, 83.3% (255/306; 95% CI 87.8%-95.0%) for 14-day high-dose dual therapy, and 90.2% (276/306; 95% CI 87.8%-95.0%) for 10-day bismuth quadruple therapy. Both hybrid therapy (difference 8.2%; 95% CI 4.5%-11.9%; P = 0.002) and bismuth quadruple therapy (difference 6.9%; 95% CI 1.6%-12.2%; P = 0.012) were superior to high-dose dual therapy and were similar to one another. The frequency of adverse events was 27% (81/303) with 14-day hybrid therapy, 13% (40/305) with 14-day high-dose dual therapy, and 32% (96/303) with 10-day bismuth quadruple therapy. Patients receiving high-dose dual therapy had the fewest adverse events (both P < 0.001). Fourteen-day hybrid therapy and 10-day bismuth quadruple therapy are more effective than 14-day high-dose dual therapy in the first-line treatment of H. pylori infection in Taiwan. However, high-dose dual therapy has fewer adverse effects than hybrid bismuth quadruple therapies.

A standard bismuth quadruple therapy, a fluoroquinolone-containing triple (or quadruple) therapy or a proton pump inhibitor (PPI)-amoxicillin high-dose dual therapy has been recommended as a second-line treatment for Helicobacter pylori infection by the Maastricht VI/Florence Consensus Report. The major shortcoming of levofloxacin-amoxicillin triple therapy is low cure rate for eradicating levofloxacin-resistant strains. With the rising prevalence of levofloxacin-resistant strains, levofloxacin-amoxicillin triple therapy cannot reliably achieve a high eradication rate for second-line treatment of H. pylori infection in most countries now. The present article aims to review current second-line eradication regimens with a per-protocol eradication rate exceeding 85% in most geographic areas. Recently, a novel tetracycline-levofloxacin quadruple therapy consisting of a PPI, bismuth, tetracycline, and levofloxacin for rescue treatment of H. pylori infection has been developed. The new therapy achieved a higher per-protocol eradication rate than levofloxacin-amoxicillin triple treatment in a randomized controlled trial (98% versus 69%). Additionally, the tetracycline-levofloxacin quadruple therapy also exhibits a higher eradication rate than amoxicillin-levofloxacin quadruple therapy. High-dose dual PPI-amoxicillin therapy is another novel second-line treatment for H. pylori infection. The new therapy can achieve an eradication rate of 89% by per-protocol analysis for the second-line treatment in Taiwan. Recently, levofloxacin-based sequential quadruple therapy and potassium-competitive acid blocker have also been applied in the second-line treatment of H. pylori infection. A meta-analysis revealed that a vonoprazan-based regimen has significant superiority over a PPI-based regimen for second-line H. pylori eradication therapy. In conclusion, the eradication rate of levofloxacin-amoxicillin triple therapy is suboptimal in the second-line treatment of H. pylori infection now. Currently, a standard bismuth quadruple therapy (tetracycline-metronidazole quadruple therapy), a tetracycline-levofloxacin quadruple therapy, an amoxicillin-levofloxacin quadruple therapy, a levofloxacin-based sequential quadruple therapy or a high-dose PPI-amoxicillin dual therapy is recommended for the second-line treatment of H. pylori infection.

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.

Colorectal polyps are the precursor lesions of most colorectal cancers. This study aimed to evaluate associations between bone mineral density (BMD), metabolic syndrome (MetS), and gastrointestinal diseases with colorectal polyps in middle-aged and elderly populations. A retrospective cross-sectional study was performed using data from the health examination database of a tertiary medical center in southern Taiwan in 2015. Subjects aged 50 years and older who had been assessed for metabolic factors and had undergone colonoscopy, upper gastrointestinal endoscopy, and dual energy X-ray absorptiometry scan (DEXA) were included. Factors associated with colorectal polyps were evaluated using univariate and multivariate logistic regression. In total, 1515 subjects were included, with mean age 60.1 years. Among them, 710 (46.9%) had colorectal polyps. Multivariate logistic regression analysis showed that high fasting glucose (OR = 1.08, p = 0.001), high triglycerides (OR = 1.02, p = 0.008), high total cholesterol (OR = 1.004, p = 0.009), reflux esophagitis (OR = 1.44, p = 0.002), duodenal polyps (OR = 1.75, p = 0.026), gastric ulcer (OR = 1.38, p = 0.024), duodenal ulcers (OR = 1.45, p = 0.028), osteopenia (OR = 1.48, p = 0.001), and MetS (OR = 1.46, p < 0.001) were independently associated with colorectal polyps. In conclusion, hyperglycemia, hypercholesterolemia, hypertriglyceridemia, MetS, duodenal polyps, gastric and duodenal ulcers, reflux esophagitis, and low BMD are independent risk factors associated with colorectal polyps in the middle-aged and elderly Taiwanese population.

The gut microbiota plays a role in nonalcoholic fatty liver disease (NAFLD), but data about gut dysbiosis in Asians with NAFLD remains scarce. We analyzed the differences in fecal microbiota between adults with and without NAFLD. This cross-sectional study examined adults with histology-proven NAFLD (25 nonalcoholic fatty liver (NAFL) patients, 25 nonalcoholic steatohepatitis (NASH) patients, and 25 living liver donors (healthy controls)). The taxonomic composition of the gut microbiota was determined by 16S ribosomal RNA gene sequencing of stool samples. The NAFL and NASH groups showed lower total bacterial diversity and richness than the controls. NAFLD patients had higher levels of the phylum Bacteroidetes and lower levels of Firmicutes than controls. The genus Ruminococcaceae UCG-010, family Ruminococcaceae, order Clostridiales, and class Clostridia were less abundant in patients with NAFL or NASH than healthy individuals. The lipopolysaccharide biosynthesis pathway was differentially enriched in the NASH group. This study examined the largest number of Asian patients with biopsy-proven NAFL and NASH in terms of dysbiosis of the gut microbiota in NAFLD patients. NAFLD patients had higher levels of Bacteroidetes and lower levels of Firmicutes. These results are different from research from western countries and could provide different targets for therapies by region.

There is an increasing trend in the incidence of gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) worldwide. The aim of the present study was to identify the prognostic factors of patients with GEP-NENs. A cross-sectional, retrospective chart review study was conducted among patients with pathologically proven GEP-NENs between January 2003 and December 2016 at Kaohsiung Chung-Gung Memorial Hospital. A total of 97 patients who met the inclusion criteria were included (male/female = 56/41, age: 57.7 ± 15.4 years). The presentation, clinical characteristics, and disease outcomes were reviewed and analyzed. The most common primary site of the GEP-NENs was the rectum (49.5%), followed by the pancreas (17.5%), duodenum (11.3%), stomach (10.3%), colon (6.2%), and appendix (5.2%), and most GEP-NENs were hormonally nonfunctional (94.8%). There were 56 tumors classified as G1 neuroendocrine tumors (NETs), 9 as G2 NETs, and 14 as G3 neuroendocrine carcinoma (NEC). Metastasis was found in 15 patients (15%). Curative treatments, such as surgery or endoscopic resection, were performed in 83.5% of patients (n = 81). The mean overall survival duration was 107.2 ± 7.8 months. The estimated 3- and 5-year overall survival rates for all patients were 84% and 82%, respectively. Logistic regression analysis showed that large tumor size, non-rectal NENs, high histopathological grading, lymphatic metastases and distant metastases were associated with poor survival. This study suggested that the presence of lymphatic or distant metastases at diagnosis is an independent risk factor for poor prognosis in patients with GEP-NENs.

Endoscopic submucosal dissection (ESD) as an advanced endoscopic procedure can be considered for the removal of colorectal lesions with high suspicion of limited submucosal invasion or cannot be optimally removed by snare-based techniques. We aimed to analyze the clinical outcomes of ESD for colorectal neoplasms in our hospital. We retrospectively enrolled 230 patients with 244 colorectal neoplasms who received ESD procedures from April 2012 to October 2020 at Kaohsiung Chang Gung Memorial Hospital. Clinicopathological data were collected by chart review. We also recorded ESD-related complications and clinical outcomes. The average age was 64 years old, with a mean follow-up time of 22.59 months. There was a loss of follow-up in 34 lesions. Most lesions were lateral spreading tumors of the non-granular type. The average ESD time was 51.9 minutes. Nine cases (3.7%) had procedure-related complications, including two intra-procedure perforations (0.8%) and seven delayed bleeding (2.9%) without procedure-related mortality. 241 lesions (98.8%) achieved en-bloc resection, while 207 lesions (84.8%) achieved R0 resection. Most lesions were tubulo-(villous) adenoma. Malignancy included 35 adenocarcinomas and 5 neuroendocrine tumors. No local recurrence was developed during follow-up. Multivariate analysis for long ESD time revealed significance in size [greater than or equal to] 10 cm.sup.2 and endoscopist's experience < 3 years. Pre-ESD endoscopic ultrasound revealed good prediction in discrimination of mucosal (sensitivity: 0.90) and submucosal lesion (specificity: 0.67). ESD for colorectal neoplasms is an effective and safe technique. Size [greater than or equal to] 10 cm.sup.2 and endoscopist's experience < 3 years were significantly associated with long procedure time. Pre-ESD EUS provided a good prediction for colorectal neoplasms in invasion depth.

Platelets catalyze the development of hyperinflammation and microthrombosis and contribute to increases in accumulation of circulating platelet-leukocyte complex, the key event in the development of disseminated infection. To determine the relationships of platelet activity in diabetic patients with invasive liver abscess syndrome (IKLAS), a total of 175 diabetic patients with community-acquired (KP) bacteremia were included in this study. We compared the platelet reactivity of 40 patients with IKLAS, 40 patients with non-IKLAS, and eight healthy controls using a whole-blood flow cytometry-based assay. Patients who were infected with strains expressing K /K serotype (adjusted odds ratio [AOR], 8.81; 95% CI, 2.18-35.53) and those with HbA ≥9% (AOR, 4.97; 95% CI, 1.73-14.23) were more likely to present with IKLAS, whereas those who had recent therapy with aspirin (AOR, 0.17; 95% CI, 0.04-0.79) were less likely to present with IKLAS. Among patients with IKLAS, patients with a poor glycemic control were more likely to present with hepatic venous thrombo-phlebitis than those with suboptimal or good glycemic control ( =0.03). Patients with IKLAS had a higher median fluorescence intensity of the platelet membrane expression of P-selectin than those with non-IKLAS (78.0 vs 28.0, <0.001) and controls (78.0 vs 22.0, < 0.001). The IKLAS group also demonstrated a significantly higher platelet-monocyte aggregation and higher plasma levels of PF-4 than the non-IKLAS group (47.0 vs 18.0 and 47.0 vs 4.0, respectively, both <0.001) and controls (46.0 vs 24.0 and 46.0 vs 13.0, respectively, both <0.001). Diabetic patients with IKLAS demonstrated platelet hyperreactivity, which may be associated with a higher risk for vascular complications.

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. 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. 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 =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; =0.0058) but decreased the risks for acute pancreatitis (aHR=0.72; 95% CI=0.60-0.85; =0.0002) and cholangitis (aHR= 0.91; 95% CI=0.84-0.99; =0.0259). There was no significant difference about recurrent choledocholithiasis between groups. 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.
