Treatment of Helicobacter pylori (H. pylori) infection is paramount for the management of prevalent gastrointestinal disorders and in the prevention of gastric cancer. Due to increasing antimicrobial resistance, performance of standard triple therapies has now declined to unacceptably low levels.. In this article: i) we critically revise optimization tools aiming to improve the outcome of standard treatments; ii) we provide updated evidence on the efficacy and rationale for the use of several non-bismuth quadruple regimens in clinical practice, recommended as preferred empirical therapies in areas of high clarithromycin resistance.. Prolonged (14-day) treatment duration may boost the efficacy of standard triple therapy by approximately 5%. Use of a high-dose PPI and/or new-generation PPIs, rabeprazole and esomeprazole, might improve eradication rates, particularly in regions where the CYP2C19 rapid metabolizer phenotype is prevalent. Adjunctive probiotics may be considered to improve treatment tolerability, though more data are required to better define their role in H. pylori eradication. Among non-bismuth quadruple regimens, both concomitant and sequential therapies are appropriate options for high-resistance settings; however, concomitant therapy appears to be less impaired by dual clarithromycin/metronidazole resistance. Hybrid therapy is a promising new alternative which seems not to be inferior to concomitant therapy.

Clinical and basic mechanisms of interaction between Helicobacter pylori and its host have been the subject of numerous publications in the past year. Two additional proton pump inhibitors (PPIs), esomeprazole and rabeprazole, have shown effectiveness in H. pylori eradication when combined with amoxicillin and clarithromycin, and esomeprazole has demonstrated its effectiveness with only one daily dose. Other important recent developments worldwide include evidence-based treatment guidelines established at a European consensus meeting, improved accuracy in the urea breath test and the stool antigen test, new recommendations for second-line therapy, and a greater understanding of antimicrobial resistance in treatment failure. In addition, new studies have confirmed that H. pylori infection and use of nonsteroidal anti-inflammatory drugs or aspirin are the major causes of peptic ulcer disease and ulcer bleeding. This paper reviews the results of these studies and their implications for future research.

We investigated to compare the effect of empirical therapy vs clarithromycin resistance-guided tailored therapy (tailored therapy) for eradication of Helicobacter pylori.. In this prospective, single center, open-label randomized controlled trial, we enrolled 72 patients with H. pylori infection from January 2019 through June 2019 in Korea. The patients were randomly assigned to both groups received empirical (n = 36) or tailored therapy (n = 36). Empirical therapy was defined as triple therapy with esomeprazole, amoxicillin, and clarithromycin for 10 days irrespective of clarithromycin resistance. Tailored therapy was triple or quadruple therapy with esomeprazole, metronidazole, tetracycline, and bismuth for 10 days based on genotype markers of resistance determined by gastric biopsy. Resistance-associated mutations in 23S rRNA were confirmed by multiplex polymerase chain reaction. Eradication status was assessed by C-urea breath test, and the primary outcome was eradication rates.. H. pylori was eradicated in 27 patients (75.0%), given empirical therapy and 32 patients (88.9%) treated with tailored therapy (P = 0.136) in intention-to-treat analysis. In per protocol analysis, the eradication rate was 97.0% and 81.8% in tailoredvs empirical groups (P = 0.046). Although clarithromycin-resistant H. pylori was eradicated in 3/9 (33.3%) with empirical therapy, it was treated in 11/12 (91.7%) with tailored therapy (P = 0.009). There was no difference in compliance between 2 groups. The rate of adverse events of the tailored group was higher than that of the empirical group (P = 0.036) because quadruple therapy had more side effects than those of triple therapy (P = 0.001).. Tailored therapy based on polymerase chain reaction is a good alternative to increase eradication rates in a region of high prevalence of clarithromycin resistance (see Visual Abstract, Supplementary Digital Content 1, http://links.lww.com/CTG/A342).

Objective Gastric endoscopic submucosal dissection (ESD) is currently a standard procedure, and proton pump inhibitors (PPIs) are most commonly used to treat post-ESD ulcers. Vonoprazan, a potassium-competitive acid blocker (P-CAB), reportedly inhibits gastric acid secretions more effectively than PPIs. Combination therapy of a PPI plus rebamipide is effective for treating larger ulcers. Our goal was to evaluate the effects of vonoprazan plus rebamipide compared to esomeprazole plus rebamipide for the treatment of post-ESD ulcers. Methods First, vonoprazan plus rebamipide (V group) or esomeprazole plus rebamipide (E group) was orally administered to subjects for eight weeks. We then evaluated the ulcer healing process at four and eight weeks after the procedure using a gastric ulcer stage system and by measuring the ulcer size. Patients A total of 84 patients who underwent ESD for gastric neoplasms between September 2015 and December 2017 in Tsuchiura Kyodo General Hospital were included in this randomized controlled trial. Results The ulcer scar rates at week 4 in the V group (n=43) and E groups (n=39) were 20.9% and 15.4%, while those at week 8 were 90.7% and 92.3%, respectively. The ulcer reduction rates at week 4 in the V and E groups were 94.6% and 93.8%, and those at week 8 were 99.7% and 99.3%, respectively. The ulcer scar rates and reduction rates were not significantly different between the two groups. Conclusion Combination therapy consisting of vonoprazan plus rebamipide was not superior to that of esomeprazole plus rebamipide for post-ESD ulcer healing (UMIN000019516).

Endoscopic submucosal dissection (ESD) is a standard procedure for treating gastric neoplasms. However, ESD causes larger artificial ulcers other than mucosal resection methods. We conducted this prospective randomized controlled study to evaluate the effect of stronger acid suppression on ESD ulcers caused by doubling the proton pump inhibitor (PPI) dose and compare the effects of 20-mg (standard dose) and 40-mg (double dose) esomeprazole (EswonampTM, Daewon Pharmaceutical Co., Ltd., Seoul, Korea) on ulcer healing.. One hundred ninety-seven patients who underwent gastric ESD from July 2017 to December 2017 at Pusan National University Yangsan Hospital were enrolled and randomly assigned to the standard or double-dose group. Change in ulcer size from the day of ESD to 4 weeks after ESD and the scar-change rate were compared between the groups.. There were no significant differences in ulcer contraction (84.5% in 20 mg group vs 86.3% in 40 mg group, P = .91) or scar-change rate (30.9% vs 30.6%, P > .99) between the groups. In a multivariate analysis, initial ulcer size [odds ratio (OR) 0.24; 95% confidence interval (CI) 0.11-0.50] and early gastric cancer (OR 0.22, 95% CI 0.08-0.58) were significantly associated with delayed ulcer healing.. Both 40 and 20-mg esomeprazole have similar effects on ESD-induced ulcer area reduction, suggesting that strong acid suppression does not necessarily result in rapid artificial ulcer healing.. RCT no.: KCT0002885.

Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers.. We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD.. A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241).. Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice.

To investigate the optimum period of treatment for post endoscopic submucosal dissection (ESD) ulcers.. Patients who underwent ESD for gastric cancer were randomized to two groups and treated with esomeprazole 20 mg per day for 4 wk (4W group) or 2 wk (2W group). At 4 wk after ESD, we measured the size of the artificial ulcers by endoscopy and determined the ulcer healing rate, compared with the size of the ESD specimens. This randomized controlled trial study was approved by our ethics committee and registered in the UMIN Clinical Trial Registry.. A total of 60 consecutive patients were included in the study. All patients received rebamipide 300 mg per day for 4 wk. One patient in 2W group who showed bleeding within two weeks and received endoscopic treatment was excluded from further analysis. The numbers of patients with ulcers in the healing/scar stage in the 2W and 4W groups at 4 wk after ESD were 20/6 and 28/5, respectively, with no significant difference. The ulcer healing rate in the 2W and 4W groups were 96.1% [95% confidence interval (CI): 94.6%-97.55] vs 94.8% (95%CI: 92.6%-97.1%), respectively, with no statistical difference (UMIN000006951).. Two-wk treatment with a proton pump inhibitor is as effective as four-week treatment for healing post ESD ulcers.

The increasing trend of antibiotic resistance requires effective second-line Helicobacter pylori (H. pylori) treatment in high prevalence area of H. pylori. The aim of our study was to evaluate the reinfection rate of H. pylori after second-line treatment that would determine the long-term follow up effect of the rescue therapy.. A total of 648 patients who had failed previous H. pylori eradication on standard triple therapy were randomized into two regimens: 1, esomeprazole (20 mg b.i.d), tripotassium dicitrate bismuthate (300 mg q.i.d), metronidazole (500 mg t.i.d), and tetracycline (500 mg q.i.d) (EBMT) or 2, moxifloxacin (400 mg q.d.), esomeprazole (20 mg b.i.d), and amoxicillin (1000 mg b.i.d.) (MEA). At four weeks after completion of eradication therapy, H. pylori tests were performed with 13C urea breath test or invasive tests. In patients who maintained continuous H. pylori negativity for the first year after eradication therapy, H. pylori status was assessed every year. For the evaluation of risk factors of reinfection, gender, age, clinical diagnosis, histological atrophic gastritis or intestinal metaplasia were analyzed.. The recrudescence rate of the EBMT was 1.7% and of the MEA group 3.3% (p = 0.67). The annual reinfection rate of H. pylori of EBMT was found to be 4.45% and the MEA group 6.46%. Univariate analysis (Log-rank test) showed no association with any clinical risk factor for reinfection.. The long-term reinfection rate of H. pylori stayed low in both of bismuth-containing quadruple therapy and moxifloxacin-based triple therapy; thus reinfection cannot affect the choice of second-line treatment.. Clinical Trial Registration Number NCT01792700.

This study aimed to determine whether Helicobacter pylori eradication limits the progression of precancerous changes, manifested as intestinal metaplasia (IM), in patients with reflux esophagitis using long-term esomeprazole.. Three hundred twenty-five reflux esophagitis patients were enrolled and randomly assigned to (i) the H. pylori-positive eradication group receiving 1-week triple therapy (n=105); (ii) H. pylori-positive non-eradication controls (n=105); and (iii) H. pylori-negative controls (n=115). All the patients received continuous esomeprazole until sustained symptomatic response, and when possible, shifted to on-demand therapy (ODT) thereafter. Serial gastroscopy was scheduled on enrollment and at the end of the first and second years to assess the prevalence and progression or regression of gastric atrophy (AT) and IM.. There were 93 patients in the H. pylori-eradication group, 83 in the non-eradication controls, and 100 in the negative controls to complete the study. The negative controls had no progression of AT and IM during follow-up. For the H. pylori-positive eradication group, there was significant regression of AT and IM during follow-up (P<0.05). In the H. pylori-positive non-treated controls, the prevalence rates of AT and IM were significantly greater on the second year than on enrollment (P<0.05). During the second-year follow-up, the patients in the eradication group achieved more regression and less development of AT and IM than did the non-eradication controls (P<0.001).. In patients using long-term esomeprazole for reflux esophagitis, screening for and eradicating H. pylori infection are necessary in order to limit the progression or cause the regression of gastric precancerous changes.

Gastric cancer is a common gastrointestinal malignancy worldwide, with a high mortality rate and poor prognosis. Esomeprazole (ESO) has been shown to have anticancer activity by affecting cell growth and autophagy and its mechanism in gastric cancer cells is evident. The PI3K/AKT/FOXO3a pathway is central in cancers. 3-Methyladenine (3-MA), a dual inhibitor of PI3K and autophagy, plays a synergistic role in combination with antitumor agents. In this study, we assessed the role of ESO on the PI3K/AKT/FOXO3a pathway and the beneficial effects of ESO combined with 3-MA in gastric cancer cells. Cell viability, proliferation, invasion, migration, apoptosis, autophagy, and protein expression were detected by CCK-8, EdU, Transwell, flow cytometry, immunofluorescence assay, and western blot. ESO decreased cell viability in a concentration- and time-dependent manner and increased autophagy with upregulation of LC3II and P62. Additionally, ESO inhibited the proliferation, migration, and invasion and induced the apoptosis of gastric cancer cells in a concentration-dependent manner. ESO inhibited PI3K/AKT/FOXO3a signaling and EGFR and SKP2 expression concentration-dependent. 3-MA enhanced the antiproliferative activity of ESO and synergistically inhibited PI3K/FOXO3a signaling and the expression of EGFR but not SKP2. Furthermore, pretreatment with the EGFR inhibitor AG1478 enhanced the antiproliferative activity of ESO in gastric cancer cells. In conclusion, our results suggested that the PI3K inhibitor 3-MA promotes the antiproliferative activity of ESO in gastric cancer cells by synergistically downregulating EGFR via the PI3K/FOXO3a pathway.

The frequency of gastric-cancer (GC) diagnosis has been increasing in recent years and often has no obvious symptoms at an early stage. Upon clinical diagnosis of early GC (EGC), surgical treatment is generally recommended but as an invasive operation, surgical resection can't avoid postoperative gastrointestinal dysfunction (GID) and other problems.. The study intended to evaluate the clinical benefits for EGC patients of auricular point-pressing with beans, combined with esomeprazole magnesium (EM), for relieving gastrointestinal dysfunction (GID) after endoscopic submucosal dissection (ESD), aiming to provide accurate and effective reference opinions for future clinical treatment.. The research team designed a retrospective analysis.. The study took place at the Jiangsu Province Hospital of Chinese Medicine in Nanjing, Jiangsu, China.. Participants were 78 EGC patients who underwent ESD at the hospital between January 2019 and January 2021 and who had developed postoperative GID.. Thirty-seven patients chose to receive routine EM treatment, and they served as a control group. 41 patients chose to receive auricular point-pressing with bean plus EM intervention, and they served as a intervention group.. At baseline and postintervention, the research team measured the levels of serum motilin (MOT), substance P (SP), prealbumin (PAB), transferrin (TF), and albumin (ALB). They also recorded the time of intestinal peristalsis recovery, first exhaust, first defecation, normal food intake, and resolution of abdominal distension symptoms. Finally, they counted the incidence of adverse events during treatment.. The levels of MOT, SP, PAB, TF, and ALB significantly changed between baseline and postintervention in both groups (P < .05). In the intervention group as compared to the control group postintervention, the decreases in the levels of MOT PAB, TF, and ALB and the increase in the SP level were significantly greater in the control group than those of the intervention group (all P < .05). In addition, the intervention group showed a shorter recovery time related to postoperative intestinal function and normal food intake and resolution of abdominal distension symptoms than did the control group (all P < .05), with a lower incidence of adverse events.. Auricular point-pressing with beans plus EM can effectively alleviate the GID of EGC patients after ESD and help them to maintain normal gastrointestinal function, and its use is worth popularizing in clinical settings.

Proton pump inhibitors (PPIs), such as esomeprazole, pantoprazole, dexlansoprazole, and rabeprazole, are one of the most commonly prescribed medications. Several studies have linked the long-term use of PPIs to a potentially increased risk of gastric cancer. Therefore, this study aimed to determine the underlying mechanism of PPI-mediated gastric cancer.. Lysosomes were isolated using immunoprecipitation. The inhibition of vacuolar-type ATPase (V-ATPase) by PPIs was assayed using a PiColorLock Gold Phosphate Detection System. PPI-induced lysosomal stress was analyzed using transcription factor EB (TFEB) nuclear translocation. PPI-induced endoplasmic reticulum (ER) stress was analyzed using the expression of protein kinase RNA-like endoplasmic reticulum kinase (PERK), inositol-requiring enzyme 1 (IRE1), and activating transcription factor 6 (ATF6). Finally, reactive oxygen species (ROS) removal was determined using the activity of superoxide dismutase (SOD).. PPIs caused a 70% inhibition of V-ATPase activity at 20 μM, leading to lysosomal stress through TFEB nuclear translocation; ER stress by inducing the expression of PERK, IRE1, and ATF6; and enhanced SOD activity for ROS removal.. The long-term use of PPIs inhibits lysosomal V-ATPase, leading to ER stress and ROS accumulation, which may result in an increased risk of gastric cancer. Because lysosomes and the ER are common organelles in cells, physicians prescribing PPIs for gastroesophageal reflux and peptic ulcer diseases should pay more attention to the general effects of these agents on the human body.

Endoscopic submucosal dissection (ESD) is widely used as a treatment modality for gastric mucosal neoplasia. While proton pump inhibitors (PPIs) have been used for the control of artificial ulcers created by ESD (ESD-ulcers), complete healing of the ulcers is not always achieved in all the cases. The purpose of this study was to identify the clinical factors that are predictive of refractory ESD-ulcers.. We recruited 90 patients with 102 artificial ulcers that formed after the patients underwent ESD for gastric tumours. All the patients received a 20-mg capsule of esomeprazole daily until the 56th day after ESD, and underwent endoscopy at 1, 4, 6 and 8 weeks after the ESD. We analyzed the clinical factors that were associated with the complete healing at 8 weeks after the ESD (CH-8w). The ulcers in the scar stage were defined as the complete healing in this study.. Of the 102 ESD-ulcers, 16.7% failed to show complete healing after the 8 weeks of PPI therapy. Univariate analysis identified the percent reduction of the ulcer size at 4 weeks after ESD (PR-4w) as being significantly associated with CH-8w. Multivariate analysis identified ulcer location in the lower-third of the stomach and PR-4w > 95% as being independently correlated with the CH-8w (odds ratio = 4.86 and 7.89, respectively). Analysis of the area under the receiver operating characteristic (AUROC) curve demonstrated that the AUROC curve of PR-4w for predicting the CH-8w was 0.78.. Based on the results of our study, endoscopic observation at 4 weeks after ESD would help in the early identification of refractory ESD-ulcers.

Proton pump inhibitors (PPI) are effective at healing artificial ulcers after endoscopic submucosal dissection (ESD) for gastric neoplasms; however, the efficacy of vonoprazan is not completely understood. The aim of the present study was to determine the healing effect of vonoprazan on artificial ulcers post-gastric ESD relative to PPI.. Thirty-five patients who underwent gastric ESD between April and November 2015 were treated with vonoprazan 20 mg/day for 4 weeks and subsequently underwent endoscopy for evaluation of ulcer size (V group). Ulcer contraction rate was determined by the following formula: ([ESD specimen size] - [ulcer size at 4 weeks after ESD])/(ESD specimen size) × 100%. We compared the results with those of a historical control group treated with esomeprazole 20 mg/day for 4 weeks after gastric ESD and subsequently measured their ulcer size (33 patients, E group) by propensity score-matching methods.. Sixty-two subjects were enrolled after propensity score-matching. Ulcer contraction rate at 4 weeks after ESD in the V group was significantly higher than that of the E group (97.7 ± 3.2% vs 94.5 ± 6.7%, respectively, P = 0.025). Number of subjects with a scar-stage ulcer (100% contraction rate) tended to be higher in the V group relative to the E group (32% [10 of 31] vs 13% [4 of 31], respectively, P = 0.070, McNemar's chi-squared test).. Vonoprazan has a faster post-gastric ESD artificial ulcer contraction rate than esomeprazole. Vonoprazan may supersede PPI in treating post-ESD artificial ulcers of the stomach.
