Abstract
BACKGROUND AND AIM Standard 10-day sequential therapy is advised as first-line therapy for Helicobacter pylori (H. pylori) eradication by current Italian guidelines. Some data suggested that a 14-day regimen may achieve higher eradication rates. This study compared the efficacy of sequential therapy administered for either 10- or 14-days. METHODS This prospective, multicenter, open-label study enrolled patients with H. pylori infection without previous treatment. Patients were receiving a sequential therapy for either 10 or 14 days with esomeprazole 40 mg and amoxicillin 1 g (5 or 7 days) followed by esomeprazole 40 mg, clarithromycin 500 mg and tinidazole 500 mg (5 or 7 days), all given twice daily. Bacterial eradication was checked using 13C-urea breath test. Eradication cure rates were calculated at both Intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS A total of 291 patients were enrolled, including 146 patients in 10-day and 145 in the 14-day regimen. The eradication rates were 87% (95% CI = 81.5-92.4) and 90.3% (95% CI = 85.5-95.1) at ITT analysis with the 10- and 14-day regimen, respectively, and 92.7% (95% CI = 88.3-97) and 97% (95% CI = 94.2-99.9) at PP analysis (p =0.37). Among patients, who earlier had interrupted therapy, bacterial eradication was achieved in 8 out of 9 who completed the first therapy phase and performed at least >/=3 days of triple therapy in the second phase. CONCLUSION This study found that both 10- and 14-day sequential therapies achieved a high eradication rate for first-line H. pylori therapy in clinical practice.

Eur J Intern Med 2019; 59:65-69. [PMID: 30154038 DOI: 10.1016/j.ejim.2018.08.012] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 08/19/2018] [Accepted: 08/21/2018] [Indexed: 12/12/2022]
Abstract
BACKGROUND Small observational studies and case reports have indicated that proton pump inhibitors (PPIs) may cause hyponatremia. Whether there is a difference between the individual PPIs is yet unknown. Since PPIs are one of the most commonly prescribed groups of drugs, even a rare adverse reaction may have large implications. The objective was to study the association between PPIs and hospitalization due to hyponatremia. METHODS This register-based case-control study was based on the general Swedish population. Patients hospitalized with a principal diagnosis of hyponatremia (n = 14,359) were compared to matched controls (n = 57,383). The association between newly initiated (≤90 days) and ongoing PPI use was explored using multivariable logistic regression adjusting for concomitant drugs, medical conditions, previous hospitalizations and socioeconomic factors. RESULTS Adjusted ORs (95%CI) for hospitalization due to hyponatremia, compared to controls, were for newly initiated: omeprazole 2.67 (2.37-3.01); pantoprazole 2.06 (1.32-3.19); lansoprazole 1.19 (0.72-1.94); esomeprazole 2.89 (2.21-3.79) and any PPI 2.78 (2.48-3.11). Only one individual had been newly initiated on rabeprazole and had been hospitalized due to hyponatremia. Adjusted ORs (95%CI) for individuals with ongoing treatment were for: omeprazole 1.04 (0.97-1.11); pantoprazole 0.81 (0.62-1.05); lansoprazole 0.90 (0.70-1.15); rabeprazole 3.34 (0.84-11.43); esomeprazole 1.12 (0.94-1.33) and any PPI 1.04 (0.98-1.11). CONCLUSIONS With the exception of lansoprazole, this study suggests an association between any newly initiated PPI-treatment and hospitalization due to hyponatremia. Ongoing PPI use was not associated with an increased risk.

Abstract
OBJECTIVE The poor compliance to treatment of Helicobacter pylori-infected patients is well-known. We evaluated the efficacy of daily single-dose triple therapy as compared to conventional triple therapy on patient compliance and eradication of H. pylori infection. METHODS In the study group, 105 patients received esomeprazole 40 mg, tinidazole 1 g, and levofloxacin 500 mg once-daily for 14 days. One hundred and seven patients in the control group received lansoprazole 30 mg, amoxicillin 1 g, and clarithromycin 500 mg twice-daily for 14 days. Four weeks after completing therapy, urea breath test was performed to assess the eradication of H. pylori infection. RESULTS The eradication rates by intention-to-treat analysis were 86% and 90.2% and by per-protocol analyses were 90.5% and 95.3% in the control and study groups, respectively, with no significant differences. Drug compliance was significantly better in the study group compared to the control group (p = 0.04). Overall, 44.7% of the patients in the study and 47.6% in the control groups had at least one adverse event. The most common adverse event was the dysgeusia in both the groups. The occurrence of diarrhea, nausea and vomiting was significantly higher in the control group and that of arthralgia was higher in the study group. The presence of periodontal disease and drug compliance was independently associated with treatment failure. CONCLUSION The use of single-dose PPI-based triple therapy improves drug compliance and eradication rate to standard PPI-based triple therapy. Presence of periodontal disease and drug compliance had negative influence on the eradication rate. TRIAL REGISTRATION NCT02711176 ᅟ ᅟ.

Proton pump inhibitor as an independent factor of progression of abdominal aortic calcification in patients on maintenance hemodialysis. PLoS One 2018; 13:e0199160. [PMID: 29969455 PMCID: PMC6029762 DOI: 10.1371/journal.pone.0199160] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2018] [Accepted: 06/02/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUNDS Proton pump inhibitors (PPIs) can be associated with vascular calcification in patients undergoing dialysis through hypomagnesemia. However, only few studies have demonstrated the influence of PPIs on vascular calcification in patients on maintenance hemodialysis (HD). This study aimed to investigate whether the use of PPIs accelerates vascular calcification in patients on HD. MATERIALS AND METHODS We retrospectively evaluated 200 HD patients who underwent regular blood tests and computed tomography (CT) between 2016 and 2017. The abdominal aortic calcification index (ACI) was measured using abdominal CT. The difference in the ACI values between 2016 and 2017 was evaluated as ΔACI. Patients were divided into PPI and non-PPI groups, and variables, such as patient background, medication, laboratory data, and ΔACI were compared. Factors independently associated with higher ΔACI progression (≥ third tertile value of ΔACI in this study) were determined using multivariate logistic regression analysis. RESULTS The PPI and non-PPI groups had 112 (56%) and 88 (44%) patients, respectively. Median and third tertile value of ΔACIs were 4.2% and 5.8%, respectively. Serum magnesium was significantly lower in the PPI (2.1 mg/dL) than in the non-PPI (2.3 mg/dL) group (P <0.001). Median ΔACI was significantly higher in the PPI (5.0%) than in the non-PPI (3.8%) group (P = 0.009). A total of 77 (39%) patients had a higher ΔACI. Multivariate analysis revealed that PPIs (odds ratio = 2.23; 95% confidence interval = 1.11-4.49), annual mean calcium phosphorus product, ACI in 2016, baseline serum magnesium levels, and HD vintage were independent factors associated with higher ΔACI progression after adjusting for confounders. CONCLUSION PPI use may accelerate vascular calcification in patients on HD. Further studies are necessary to elucidate their influence on vascular calcification.

Abstract
AIM To evaluate GI safety of celecoxib compared with 2 nonselective (ns) NSAIDs, as a secondary objective of a large trial examining multiorgan safety. METHODS This randomised, double-blind controlled trial analysed 24 081 patients. Osteoarthritis or rheumatoid arthritis patients, needing ongoing NSAID treatment, were randomised to receive celecoxib 100-200 mg b.d., ibuprofen 600-800 mg t.d.s. or naproxen 375-500 mg b.d. plus esomeprazole, and low-dose aspirin or corticosteroids if already prescribed. Clinically significant GI events (CSGIE-bleeding, obstruction, perforation events from stomach downwards or symptomatic ulcers) and iron deficiency anaemia (IDA) were adjudicated blindly. RESULTS Mean treatment and follow-up durations were 20.3 and 34.1 months. While on treatment or 30 days after, CSGIE occurred in 0.34%, 0.74% and 0.66% taking celecoxib, ibuprofen and naproxen. Hazard ratios (HR) were 0.43 (95% CI 0.27-0.68, P = 0.0003) celecoxib vs ibuprofen and 0.51 (0.32-0.81, P = 0.004) vs naproxen. There was also less IDA on celecoxib: HR 0.43 (0.27-0.68, P = 0.0003) vs ibuprofen; 0.40 (0.25-0.62, P < 0.0001) vs naproxen. Even taken with low-dose aspirin, fewer CSGIE occurred on celecoxib than ibuprofen (HR 0.52 [0.29-0.94], P = 0.03), and less IDA vs naproxen (0.42 [0.23-0.77, P = 0.005]). Corticosteroid use increased total GI events and CSGIE. H. pylori serological status had no influence. CONCLUSIONS Arthritis patients taking NSAIDs plus esomeprazole have infrequent clinically significant gastrointestinal events. Co-prescribed with esomeprazole, celecoxib has better overall GI safety than ibuprofen or naproxen at these doses, despite treatment with low-dose aspirin or corticosteroids.

Abstract
OBJECTIVE Acid suppression with histamine-2 receptor antagonists (H2RAs) or proton pump inhibitors (PPIs) is recommended for children with persistent gastroesophageal reflux disease symptoms. In this retrospective, observational postauthorization study, we aimed to assess and compare safety outcomes in pediatric first-time users of esomeprazole, other PPIs or H2RAs. METHODS Data on children (aged 0-18 years) first dispensed esomeprazole, other PPIs or H2RAs between September 2008 and August 2011 was obtained from the Dutch PHARMO Database Network. Hospitalizations for seven predefined safety outcomes were evaluated (maximum follow-up: 18 months). Rate ratios were calculated using Poisson regression adjusted for baseline imbalances. Discharge letters were reviewed for event occurrence confirmation. RESULTS Of 23,470 included children, 2820 (median age: 3 years) were prescribed esomeprazole, 13,818 (median age: 15 years) other PPIs and 6832 (median age: 5 years) H2RAs. In total, 504 (2%) children were hospitalized for 762 predefined events: gastroenteritis (246); convulsion/seizure (200); pneumonia (154); failure to thrive (119); acute interstitial nephritis (19); thrombocytopenia (23); and angioneurotic edema (1). Significant differences between cohorts were observed only for failure to thrive, with adjusted rate ratios (95% confidence interval) for esomeprazole of 6.1 (2.4-15.7) vs. other PPIs and 6.1 (2.9-12.8) vs. H2RAs among current users. Occurrence was confirmed for 74% of assessable events. Confirmation rates were highest for pneumonia (81%) and lowest for failure to thrive (40%). CONCLUSIONS Hospitalization rates for predefined outcomes were low and mostly similar in pediatric first-time users of PPIs and of H2RAs. TRIAL REGISTRATION NCT01338363.

Abstract
BACKGROUND AND AIMS Helicobacter pylori (H. pylori) eradication in patients who failed one or more therapeutic attempts remains challenging. This study aimed to assess the efficacy of three-in-one capsules bismuth-based quadruple therapy (Pylera®) in these patients managed in clinical practice. METHODS This was a prospective, open-label, multicenter study enrolling consecutive, adult patients with persistent H. pylori infection following at least one standard therapy. All patients received a rescue quadruple therapy with Pylera (3 capsules four times daily) and esomeprazole 20 mg (1 tablet twice daily) for 10 days. H. pylori eradication was assessed by using Urea Breath Test 4-6 weeks following therapy ending. H. pylori eradication rates, compliance, and side-effects were calculated. RESULTS A total of 208 patients in the 9 participating centres were enrolled. Overall, 180 patients were successfully cured from the infection, accounting for 86.5% (95% CI 81.9-91.2) and 92.3% (95% CI 88.6-96.1) eradication rates at intention-to-treat analysis and at per protocol analysis, respectively. Cure rates were similar across patients who failed one to three previous therapy attempts, but the success rate fell to 67% after 4 or more therapy failures. Compliance to therapy was good in 198 (95.2%) patients, whilst in 7 (5.3%) cases the therapy was interrupted within 5 days due to side effects. A total of 97 (46.6%) patients complained of at least one side effect; nausea, diarrhea and vomiting were the most frequently reported. CONCLUSIONS Our study found that this bismuth-based quadruple therapy is highly effective as second-line and rescue therapy for H. pylori eradication in clinical practice.

Abstract
BACKGROUND The aim of the present open-label, randomized control trial was to determine the clinical efficacy and safety of two 1-week bismuth-containing quadruple regimens and 1 levofloxacin-based triple regimen for the eradication of Helicobacter pylori infection in treatment-naive patients. The influence of susceptibility and host CYP2C19 polymorphisms on the efficacy was also evaluated. METHODS Eligible patients were randomly to receive esomeprazole and colloidal bismuth pectin along with clarithromycin and amoxicillin (EBCA), esomeprazole and colloidal bismuth pectin along with levofloxacin and amoxicillin (EBLA), or esomeprazole along levofloxacin and amoxicillin (ELA) for 1 week. The primary outcome was the eradication rate in the intention-to-treat (ITT) and per-protocol (PP) analyses. RESULTS Overall, 270 patients were randomized. The eradication rates in the above 3 groups were 80.25%, 89.66%, and 81.93% in PP analysis and 72.22%, 86.66%, and 75.56% in ITT analysis, respectively. The eradication rate of EBLA was significantly higher than that of EBCA (P = 0.016) in ITT analysis. No significant differences were found among these groups in terms of adverse effects and compliance. The efficacy was significantly affected by levofloxacin resistance for EBLA (P = 0.01) and ELA (P = 0.04), but not by polymorphisms of CYP2C19 gene for any of the 3 groups. CONCLUSION All 1-week bismuth-containing quadruple therapies and levofloxacin-based triple therapy can obtain an acceptable eradication rate, and levofloxacin-based quadruple regimen exhibits the highest eradication rate. The antibiotic resistant rate of levofloxacin was associated with the eradication rate.

Abstract
BACKGROUND AND AIMS Literature data suggest an association between Helicobacter pylori infection and glucose homeostasis. However, a causative link between them has not been demonstrated yet. The aim of this study is to investigate the effect of H. pylori eradication on glucose homeostasis in patients with type 2 diabetes. METHODS AND RESULTS A randomized, double-blind, placebo-controlled trial was conducted to investigate the effect of H. pylori eradication on glucose homeostasis in 154 patients with type 2 diabetes and who tested positive for H. pylori infection (mean age (SD), 63.1 (8.1) years). Subjects were assigned to H. pylori eradication treatment or placebo. Metabolic and inflammatory parameters were measured in all subjects at baseline and 4 weeks after the treatment. H. pylori eradication led to an improvement in glucose homeostasis, measured by HOMA-IR (p < 0.001) and KITT (0 = 0.041), due to the decrease in fasting insulin levels (p = 0.004). The results also showed that lower levels of inflammatory parameters were present after eradication. CONCLUSION To our knowledge this is the first randomized, double blind, controlled study where the effect of H. pylori eradication on glucose homeostasis in subjects with type 2 diabetes has been investigated. Our findings demonstrate that H. pylori eradication improves glucose homeostasis in patients with type 2 diabetes through a decrease in pro-inflammatory factors.

Abstract
Because of the efficacy of proton pump inhibitors (PPIs), their the use is increasing dramatically. The risk of adverse effects of short-term PPI therapy is low, but there are important safety concerns for potential adverse effects of prolonged PPI therapy. Findings from studies assessing the association between PPI use and bone mineral density (BMD) and/or fracture risk are contradictory. The aim of this study was to prospectively assess potential association of PPI treatment with the 12-month change in BMD of the lumbar spine, femur neck, and total hip. The study was performed in 200 PPI users and 50 PPI nonusers. Lumbar spine (L1-L4), femur neck, and total hip BMD were measured by dual-energy X-ray absorptiometry at the baseline and at 12 months. A total of 209 subjects completed the entire 12 months of the study and were included in the final analysis. A Wilcoxon signed-rank test showed that at 12 months PPI use was associated with statistically significant reductions in femur neck and total hip T scores (Z = -2.764, p = 0.005 and Z = -3.281, p = 0.001, respectively). A multiple linear regression analysis showed that only esomeprazole added significantly to the prediction of total lumbar spine and femur neck T scores (p = 0.048 and p = 0.037, respectively). Compared with the baseline, 12 months of PPI treatment resulted in lower femur neck and total hip BMD T scores. Among the four PPIs studied, esomeprazole was independently associated with significant reduction of BMD, whereas omeprazole had no effects on BMD. Considering the widespread use of PPIs, BMD screening should be considered in the case of prolonged PPI use.

Abstract
BACKGROUND Proton pump inhibitors are usually safe, although serious adverse effects can occur. We report the first case of rhabdomyolysis associated with single-dose intravenous esomeprozole administration. METHODS A 45-year-old Korean male visited our emergency room because of persistent lower chest discomfort that started 10 hours before. He had been diagnosed with diabetes and coronary heart disease, but discontinued oral hypoglycemic agents 1 month earlier. He continued to take medications for coronary heart disease. There was no abnormality on an electrocardiogram or in cardiac enzymes. Initial laboratory findings did not show abnormalities for muscle enzymes. Esomeprozole 40 mg was administrated intravenously for the control of his ambiguous chest discomfort. Then, 12 hours later, he complained of abrupt severe right buttock pain. An area of tender muscle swelling 8 cm in diameter was seen on his right buttock area. Creatine kinase and lactate dehydrogenase were elevated to 40,538 and 1326 U/L, respectively. A bone scan using 20 mCi of Tc-hydroxymethylene diphosphonate was compatible with rhabdomyolysis. RESULTS His muscular symptoms, signs, and laboratory findings improved markedly with conservative management, including hydration and urine alkalinization. He is being followed in the outpatient department with no evidence of recurrence. CONCLUSION We should keep in mind that single-dose intravenous administration of esomeprazole can induce rhabdomyolysis.

Abstract
Here we aimed to evaluate the effectiveness of esomeprazole treatment strategies comparing with other proton pump inhibitors (PPI) in clinical practice for six months in the management of patients with symptomatic gastroesophageal reflux disease (GERD). An extensive search of the literature focusing on PPI therapeutic evaluation was performed up to December 2014. Risk ratio (RR) with its corresponding 95% confidence intervals (CIs) in each study was chosen as the effect size. Cochrane's Q statistic and I2 test were both conducted to evaluate heterogeneity across individual studies. Meta-regression was conducted to explore the source of heterogeneity and sensitive analysis was performed to assess the risk bias for the meta-analysis. Totally, eleven trials with high quality enrolled in the meta-analysis. Esomeprazole therapy (20 mg daily) had lower relapse rates than other drugs during six months maintenance treatment (RR = 0.67; 95% CI: 0.55-0.83). Heartburn (RR = 0.72; 95% CI: 0.57-0.92) and epigastric pain (RR = 0.82, 95% Cl: 0.70-0.96) were less likely to happen after esomeprazole treatment, and no significant advantage was found on acid regurgitation and dysphagia. Moreover, lower risk for serious adverse events was observed after esomeprazole therapy (RR = 1.40, 95% CI: 1.04-1.88). Blind method or difference controlled drugs did not influence heterogeneity across studies. Moreover, the conclusion on acid regurgitation, abdominal pain and dysphagia might be unstable. In GERD patients, esomeprazole 20 mg daily is more effective than other PPIs regarding relapse rates, symptoms of epigastric pain and heartburn, and serious adverse events.

van der Hoorn MMC, Tett SE, de Vries OJ, Dobson AJ, Peeters GMEEG. The effect of dose and type of proton pump inhibitor use on risk of fractures and osteoporosis treatment in older Australian women: A prospective cohort study. Bone 2015; 81:675-682. [PMID: 26319499 DOI: 10.1016/j.bone.2015.08.024] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2015] [Revised: 08/24/2015] [Accepted: 08/25/2015] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Proton pump inhibitors (PPIs) are among the most prescribed medications worldwide, however, there is growing concern regarding potential negative effects on bone health. The aim was to examine the effect of dose and type of PPI use on subsequent use of osteoporosis medication and fractures in older Australian women. METHODS Data were included from 4432 participants (born 1921-26) in the 2002 survey of the Australian Longitudinal Study on Women's Health. Medication data were from the national pharmaceutical administrative database (2003-2012, inclusive). Fractures were sourced from linked hospital datasets available for four major States of Australia. Competing risk regression models used PPI exposure as a time-dependent covariate and either time to first osteoporosis medication prescription or fracture as the outcome, with death as a competing risk. RESULTS Of the 2328 PPI users and 2104 PPI non-users, 827 (36%) and 550 (26%) became users of osteoporosis medication, respectively. PPI use was associated with an increased risk of subsequent use of osteoporosis medication (adjusted sub-hazard ratio [SHR]=1.28; 95% confidence interval [CI]=1.13-1.44) and subsequent fracture (SHR=1.29, CI=1.08-1.55). Analysis with PPI categorized according to defined daily dose (DDD), showed some evidence for a dose-response effect (osteoporosis medication: <400 DDD: SHR=1.23, CI=1.06-1.42 and ≥400 DDD: SHR=1.39, CI=1.17-1.65, compared with non-users; SHRs were in the same range for fractures). Esomeprazole was the most common PPI prescribed (22.9%). Analysis by type of PPI use showed an increased subsequent risk for: (1) use of osteoporosis medication for rabeprazole (SHR=1.51, CI=1.08-2.10) and esomeprazole (SHR=1.48, CI=1.17-1.88); and (2) fractures for rabeprazole (SHR=2.06, CI=1.37-3.10). Users of multiple types of PPI also had increased risks for use of osteoporosis medication and fractures. CONCLUSION An appropriate benefit/risk assessment should be made when prescribing PPIs, especially for esomeprazole and rabeprazole, as osteoporosis and fracture risks were increased in this cohort of elderly females subsequent to PPI prescription.

Abstract
AIM: To compare symptom control with esomeprazole regimens for non-erosive reflux disease and chronic gastritis in patients with a negative endoscopy.
METHODS: This randomized, open-label study was designed in line with clinical practice in China. Patients with typical reflux symptoms for ≥ 3 mo and a negative endoscopy who had a Gastroesophageal Reflux Disease Questionnaire score ≥ 8 were randomized to initial treatment with esomeprazole 20 mg once daily either for 8 wk or for 2 wk. Patients with symptom relief could enter another 24 wk of maintenance/on-demand treatment, where further courses of esomeprazole 20 mg once daily were given if symptoms recurred. The primary endpoint was the symptom control rate at week 24 of the maintenance/on-demand treatment period. Secondary endpoints were symptom relief rate, success rate (defined as patients who had symptom relief after initial treatment and after 24 wk of maintenance treatment), time-to-first-relapse and satisfaction rate.
RESULTS: Based on the data collected in the modified intention-to-treat population (MITT; patients in the ITT population with symptom relief after initial esomeprazole treatment, n = 262), the symptom control rate showed a small but statistically significant difference in favor of the 8-wk regimen (94.9% vs 87.3%, P = 0.0473). Among the secondary endpoints, based on the data collected in the ITT population (n = 305), the 8-wk group presented marginally better results in symptom relief after initial esomeprazole treatment (88.3% vs 83.4%, P = 0.2513) and success rate over the whole study (83.8% vs 72.8%, P = 0.0258). The 8-wk regimen was found to provide a 46% reduction in risk of relapse vs the 2-wk regimen (HR = 0.543; 95%CI: 0.388-0.761). In addition, fewer unscheduled visits and higher patient satisfaction supported the therapeutic benefits of the 8-wk regimen over the 2-wk regimen. Safety was comparable between the two groups, with both regimens being well tolerated.
CONCLUSION: Chinese patients diagnosed with chronic gastritis achieved marginally better control of reflux symptoms with an 8-wk vs a 2-wk esomeprazole regimen, with a similar safety profile.

Abstract
BACKGROUND/AIMS The aim of our study was to investigate the inhibitory effects on gastric acid secretion of a single oral dose of a proton pump inhibitor, esomeprazole 20 mg and omeprazole 20 mg. METHODOLOGY A total of 14 Helicobacter pylori-negative male subjects participated in this study. Intragastric pH was monitored continuously for 6 hours after a single oral dose of omeprazole 20 mg and a single oral dose of esomeprazole 20 mg. Each administration was separated by a 7-day washout period. RESULTS During the 6-hour study period, the average pH after administration of esomeprazole was higher than that after the administration of omeprazole. Also during the 6-hour study period, each of pH > 2, 3, 3.5, 4, and 5 was maintained for a longer duration after administration of esomeprazole 20 mg than after administration of omeprazole 20 mg (median: 75.4% vs. 53.8%, p = 0.0138; 52.1% vs. 33.4%, p = 0.0188; 45.8% vs. 28.2%, p = 0.0262; 42.5% vs. 20.7%, p = 0.0414; 35.8% vs. 11.6%, p = 0.0262; respectively). CONCLUSIONS In Helicobacter pylori-negative healthy male subjects, single oral administration of esomeprazole 20 mg increased the intragastric pH more rapidly than single oral administration of omeprazole 20 mg.

Abstract
BACKGROUND AND AIM This study was designed to demonstrate the safety and efficacy of esomeprazole combined with flupentixol/melitracen for the treatment of gastroesophageal reflux disease (GERD) patients with emotional disorders. METHODS Two hundred eighty-nine GERD patients with emotional disorders were divided randomly into two groups: group 1 received esomeprazole only (monotherapy) and group 2 received esomeprazole and flupentixol/melitracen (combination therapy). The patients' GERD questionnaire (GerdQ) and hospital anxiety and depression (HAD) scores were obtained before and after treatment. Changes in the scores, rates of symptom remission, and adverse effects were compared between the two groups. RESULTS After 2 weeks of treatment, the average decrease in GerdQ score in the combination group (4.04 ± 2.34) was significantly greater than that in the monotherapy group (3.34 ± 2.74; P < 0.05). Significant differences between the two groups were also found for changes in HAD anxiety scores (5.45 ± 2.41 vs 3.34 ± 2.43, P < 0.05), depression scores (5.47 ± 2.47 vs 3.00 ± 3.28, P < 0.05), and anxiety-depression scores (5.20 ± 2.71 vs 3.60 ± 2.56, P < 0.05). The remission of symptoms (eructation, abdominal pain, anorexia, and other accompanying symptoms) in the combination group was significantly better than that in the monotherapy group, and no significant difference in the incidence of adverse events was observed between the two groups. CONCLUSIONS The combination therapy has better efficacy than the monotherapy in improving the symptoms of gastroesophageal reflux in patients with emotional disorders. In addition, this combination treatment is safe, with a low incidence of adverse events.

Abstract
A multicenter, randomized, double-blind study comparing the efficacy and safety of esomeprazole 20mg/day (E20) and 10mg/day (E10) with omeprazole 10mg/day (O10) for maintenance of remission in patients with healed reflux esophagitis (RE). For RE, at week 24, the estimated Kaplan-Meier recurrence-free rates were 92.0%, 87.5%, and 82.7% in the E20, E10, and O10 groups, respectively. There was a statistically significant difference between the E20 and O10 groups (p=0.007). Drug-related adverse events tended to be mild but were reported at rates of 9.0%, 8.0%, and 5.3% in the E20, E10, and O10 groups, respectively. Compared with omeprazole, maintenance therapy with 20mg esomeprazole was generally well tolerated and effective for RE.

Abstract
OBJECTIVE To examine the effect of concomitant use of clopidogrel and PPIs in a national sample of elderly Medicare beneficiaries (age ≥65 years). METHODS A nested case-control design was employed. A cohort of Medicare beneficiaries who initiated clopidogrel and did not have any gap of ≥30 days between clopidogrel fills between July 1, 2006 and December 31, 2008 was identified from a 5% national sample of Medicare claims data. Within this cohort, cases (beneficiaries who experienced any major cardiovascular event [MCE] [acute myocardial infarction, stroke, coronary artery bypass graft, or percutaneous coronary intervention] or all-cause mortality) and controls (beneficiaries who did not experience any MCE or all-cause mortality) were identified from inpatient and outpatient claims. Cases and controls were matched on age and the time to first clopidogrel fill. Conditional logistic regression was performed on the matched sample to evaluate the association between concomitant use of clopidogrel and PPIs and adverse health outcomes (MCEs and all-cause mortality). RESULTS A total of 43,159 clopidogrel users were identified. Among them, 15,415 (35.7%) received clopidogrel and a PPI concomitantly at any time during the study period, 3502 (8.1%) experienced a MCE, 7306 (17.1%) died, and a total of 9908 (22.8%) experienced the primary composite outcome (any MCE or all-cause mortality) during follow-up. The odds ratio (OR) for the primary composite outcome was 1.26 (95% confidence interval [CI]: 1.18-1.35). Secondary analyses indicated that elderly patients using clopidogrel and a PPI concomitantly were more likely to experience all-cause mortality (OR: 1.40; 95% CI: 1.29-1.53) as compared to those receiving clopidogrel only, but not MCEs (OR: 1.06; 95% CI: 0.95-1.18). CONCLUSIONS Concomitant use of clopidogrel and PPIs was associated with a slightly increased risk of all-cause mortality but not MCEs.

Abstract
AIMS/HYPOTHESIS Recent studies suggest that proton pump inhibitor treatment may increase insulin secretion and improve glucose metabolism in type 2 diabetes. In a randomised double-blind prospective placebo-controlled 2 × 2 factorial study, we examined the effect of esomeprazole on insulin secretion, HbA(1c) and cardiovascular risk factors in type 2 diabetes. METHODS Forty-one patients with type 2 diabetes using dietary control or oral glucose-lowering treatment were randomised to receive add-on esomeprazole 40 mg (n = 20) or placebo (n = 21) for 12 weeks. Randomisation was carried out prior to inclusion on the basis of a computer-generated random-number list. The allocation sequence was concealed in sealed envelopes from the researcher enrolling and assessing participants. The study was undertaken at Steno Diabetes Center, Gentofte, Denmark. The primary outcome was change in AUC for insulin levels during a meal test. Secondary outcomes were the levels of HbA(1c) and biochemical markers of cardiovascular risk, including lipids, coagulation factors, inflammation markers, markers of endothelial function and 24 h ambulatory BP measurements. RESULTS Forty-one participants were analysed. In the esomeprazole-treated group the AUC for insulin did not change (before vs after treatment: 28,049 ± 17,659 vs 27,270 ± 32,004 pmol/l × min (p = 0.838). In the placebo group AUC for insulin decreased from 27,392 ± 14,348 pmol/l × min to 22,938 ± 11,936 pmol/l × min (p = 0.002). Esomeprazole treatment (n = 20) caused a ninefold increase in the AUC for gastrin. HbA(1c) increased from 7.0 ± 0.6% (53 ± 5 mmol/mol) to 7.3 ± 0.8% (56 ± 6 mmol/mol) in the esomeprazole-treated group and from 7.0 ± 0.6% (53 ± 5 mmol/mol) to 7.4 ± 0.8% (57 ± 6 mmol/mol) in the placebo group (n = 21) (p for difference in change >0.05). Except for BP, there were no differences between the groups in the markers of cardiovascular risk (p > 0.05). Monitoring of 24 h ambulatory BP showed a significant decrease in daytime systolic BP, daytime diastolic BP and 24 h diastolic BP in the placebo group (p < 0.05). No change in BP was seen in the patients treated with esomeprazole. CONCLUSIONS/INTERPRETATION Treatment with esomeprazole over 12 weeks did not improve insulin secretion, glycaemic control or cardiovascular disease biomarkers in patients with type 2 diabetes.

Abstract
BACKGROUND Even though proton pump inhibitors (PPIs) are commonly used in clinical practice, a limited number of studies are available about cutaneous adverse reactions from PPIs, and most of these are case reports. OBJECTIVE To demonstrate the pattern of cutaneous reactions related to PPI usage and to evaluate the risk of developing PPI drug eruptions among adult patients. METHODS We reviewed the spontaneous reports of any adverse events associated with PPI use, as reported from January 2005 through May 2010 to the Adverse Drug Reaction Center at Siriraj Hospital in Thailand. Each control was sampled from 15 patients who had consecutive hospital numbers from each study case. RESULTS The prevalence of cutaneous reactions to PPIs varied, ranging from three to 20 per 100,000 of the treated population. Sixty-four patients with a history of reaction to PPIs, and 65 controls were enrolled. Most cutaneous reactions were attributed to omeprazole (n=50; 78.1%), and the most frequently observed cutaneous reaction was maculopapular rash (43.8%). None of the patients experienced a cross-reaction between individual PPIs. CONCLUSION Cutaneous adverse reactions to PPIs range from minor drug rashes to a severe, life-threatening reaction. Individuals with a history of adverse drug reaction have an increased risk of cutaneous reaction to PPIs.

Abstract
BACKGROUND Several oral proton pump inhibitors (PPIs) are currently approved for use in pediatric patients in North America and Europe. However, when use of oral therapy is not possible or appropriate, intravenous formulations of PPIs may be helpful. Intravenous esomeprazole is approved in the United States for the short-term treatment of gastroesophageal reflux disease (GERD) with erosive esophagitis in adults and in pediatric patients 1 month to 17 years of age (inclusive) as an alternative to oral therapy. Four open-label, randomized, 2-way crossover studies in adults with GERD found no clinically relevant differences in acid suppression between repeated doses of oral and intravenous esomeprazole. However, the pharmacokinetics of intravenous esomeprazole has not been studied extensively in children. OBJECTIVE The aim of this study was to evaluate steady-state pharmacokinetics and tolerability of repeated doses of intravenous esomeprazole in children. METHODS In this multicenter, open-label study, hospitalized patients (0-17 years of age) considered for acid suppression therapy received once-daily intravenous esomeprazole sodium for injection at 0.5 mg/kg (0-1 month of age), 1.0 mg/kg (1-11 months of age), 10 mg (1-5 years of age), 10 or 20 mg (6-11 years of age), or 20 or 40 mg (12-17 years of age) for 4 days. Children 6 to 11 years of age (inclusive) were randomized in a 1:1 ratio to receive esomeprazole 10 or 20 mg, and adolescents 12 to 17 years of age (inclusive) were randomized in a 1:1 ratio to receive esomeprazole 20 or 40 mg. Blood samples were drawn pre- and post-dose. Plasma esomeprazole was measured using reversed-phase liquid chromatography and mass spectrometry. Pharmacokinetic variables were derived using mixed-effects modeling. Adverse events (AEs) were assessed. RESULTS Fifty-nine patients were randomized and 57 received the study drug. A majority of patients were white (44 white, 5 black/African American, 3 Asian, 5 other) and male (35/57). Fifty patients were eligible for pharmacokinetic analysis, including 6 to 8 patients in each age group. Esomeprazole pharmacokinetics was dose proportional and related to weight and age. Clearance increased with increasing weight and age. The mean AUC(τ) ranged from 6.9 μmol · h/L (10 mg, 6-11 years) to 17.6 μmol · h/L (40 mg, 12-17 years). The mean C(ss,max) ranged from 3.7 μmol/L (0.5 mg/kg, 0-1 month) to 10.5 μmol/L (40 mg, 12-17 years). Thirty-one patients experienced 1 or more AEs; 6 patients experienced 1 or more treatment-unrelated serious AEs. CONCLUSIONS Intravenous esomeprazole at doses resulting in targeted AUC(τ) and C(ss,max) similar to therapeutic exposure in adults appeared to be reasonably well tolerated in this small, select pediatric population.

Abstract
INTRODUCTION This study aimed to compare the efficacy and safety of quadruple therapy containing doxycycline and routine quadruple therapy for Helicobacter (H.) pylori rescue eradication in patients who had failed the one-week triple therapy. METHODS Patients who failed the first-line eradication therapy were allocated into two groups. Group A patients (n = 43) were administered esomeprazole 20 mg, bismuth potassium citrate 220 mg, amoxicillin 1 g and doxycycline 100 mg, all bid for ten days, while Group B patients (n = 42) were administered esomeprazole 20 mg bid, bismuth potassium citrate 220 mg bid, metronidazole 400 mg bid and tetracycline 750 mg q.6h, for ten days. The results of H. pylori eradication were assessed with 13C urea breath test four weeks after the therapy, and the side effects were recorded. RESULTS A total of 85 patients (average age 46.9 years) were enrolled in the study. Successful eradication rate for H. pylori was 72.5% in Group A and 64.1% in Group B, with no significant difference between the two groups. 11.6% (5/43) of patients from group A and 31.0% (13/42) from group B reported at least one adverse event. The adverse events of all 18 patients disappeared after the therapy ceased. CONCLUSION Quadruple therapy containing doxycycline is as effective as routine quadruple therapy for H. pylori rescue eradication. The regimen is well tolerated by most patients and causes fewer adverse events than routine quadruple therapy. Hence, it may be recommended as a suitable alternative H. pylori rescue regimen in China.
