Nature and treatment outcomes of bleeding post-bulbar duodenal ulcers. Dig Endosc 2022; 34:984-993. [PMID: 34609030 DOI: 10.1111/den.14160] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Revised: 09/29/2021] [Accepted: 10/01/2021] [Indexed: 02/08/2023]
Abstract
BACKGROUND Although post-bulbar duodenal ulcers (PBDUs) could become a source of upper gastrointestinal bleeding, the whole picture of the disease is unknown. We compared the characteristic features and treatment outcomes after endoscopic hemostasis between PBDUs and bulbar duodenal ulcers (BDUs). METHODS Data on duodenal ulcers with evidence of endoscopically-active bleeding were extracted from the data that were retrospectively collected from 12 institutes in Japan between 2011 and 2018. Rebleeding and in-hospital mortality were compared between patients with PBDUs and those with BDUs by logistic regression analyses. RESULTS Among 468 consecutive patients with bleeding duodenal ulcers, 96 (20.5%) had endoscopically-confirmed PBDUs. PBDUs were more frequently observed in patients with a poor general condition in comparison to BDUs. The rates of rebleeding and in-hospital mortality in patients with PBDUs were approximately three times higher than those in patients with BDUs (PBDU vs. BDU: 29.2% vs. 10.2% [P < 0.0001] and 14.6% vs. 5.1% [P = 0.0029], respectively). Although the high in-hospital mortality in PBDUs could be explained, to a lesser extent, by the likelihood of rebleeding, and, to a greater extent, by the patients' poor general condition, the presence of a PBDU itself was largely responsible for the high rebleeding rates in PBDUs. CONCLUSION This is the first study focusing on the nature and treatment outcomes of bleeding PBDUs. PBDUs were associated with much higher rebleeding and mortality rates in comparison to BDUs, and the likelihood of rebleeding may be derived from their unique anatomic location.

Abstract
INTRODUCTION A possible association between long-term proton pump inhibitors (PPI) use and chronic kidney disease (CKD) has been recently described. Due to the potential health risk of this association, in the absence of proper clinical trials, we have decided to carry out a systematic review followed by meta-analysis. EVIDENCE ACQUISITION PubMed, Cochrane Library, and Lilacs databases were searched. Studies that reported an association between PPI use and CKD or End-stage Renal Disease (ESRD) published until December 23, 2019, were included. All selected studies present high quality according to the New-Castle-Ottawa. The risk ratio (RR) and confidence interval (CI) were pooled using a random-effects model in CKD outcome analysis and fixed effects model for ESRD. A total of 10 observational studies were selected. EVIDENCE SYNTHESIS Compared to patients who did not use PPI, the RR for CKD associated with PPI use was 1.35 (95% CI 1.15-1.56) with P<0.001, and the RR for ESRD associated with PPI use was 1.49 (95% CI 1.41-1.56) with P<0.001. CONCLUSIONS This study indicates the presence of a significant association between PPI use and an increased risk of CKD and ESRD and reiterates the need for the medical prescription of this class of drugs to be made following the guidelines of the FDA.

Abstract
Background/Aims: Endoscopic submucosal dissection (ESD) for gastric neoplasms is a widely performed procedure. Local recurrence is rare, but various post-ESD scars are encountered during follow-up endoscopy. Therefore, we investigated atypical scar patterns and evaluated the associated factors.Materials and Methods: Clinicopathologic and endoscopic reviews of gastric neoplasms treated with ESD from January 2009 to December 2015 were conducted. Atypical scar patterns were classified as irregular erythema, nodularity, or mucosal defect.Results: A total of 264 patients with 274 gastric neoplasms, including 201 adenomas and 73 early gastric cancers, were enrolled. The key endoscopic findings at the resection scar were defined on the basis of gross morphology as follows: irregular erythema, mucosal defect (erosion or ulcer), and nodularity. An irregular erythema scar pattern was associated with male sex, a nodularity scar pattern with smoking, and a mucosal defect scar pattern with infra-angle location (angle and antrum) and cancer. An irregular erythema with nodularity scar pattern was also associated with male sex. An irregular erythema with nodularity and mucosal defect scar pattern was associated with liver disease and chronic kidney disease.Conclusions: The atypical scar patterns after gastric ESD are associated with various clinicopathologic factors.

Abstract
Background Compared to the general population, patients with end-stage renal disease have more gastrointestinal symptoms and a higher prevalence of peptic ulcer. Risk factors for peptic ulcer disease in patients with end-stage renal disease, however, remain poorly defined. This study aims to better identify those risk factors. Methods We analyzed 577 patients with end-stage renal disease from 2004 to 2016. We excluded patients with life-threatening conditions. All patients underwent upper endoscopy. We analyzed patient medical records, medication history, and endoscopic findings. Independent sample t test, chi-square test, Fisher’s exact test, and multiple logistic regression analysis were used in statistical analyses. Results Of the 577 patients with end-stage renal disease, 174 had peptic ulcer disease (gastric or duodenal ulcer). Patients on hemodialysis had a higher prevalence of peptic ulcer disease than those on peritoneal dialysis. Patients with peptic ulcer disease had lower serum albumin level and higher blood urea nitrogen level than those without peptic ulcer disease. Positive scores on two or more nutritional indices (albumin, serum cholesterol, uric acid, and creatinine levels) were associated with peptic ulcer disease in end-stage renal disease. Conclusion Hemodialysis, hypoalbuminemia, and multiple malnutrition indices were associated with the prevalence of peptic ulcer disease in patients with end-stage renal disease receiving dialysis.

Abstract
BACKGROUND Proton pump inhibitor use is associated with incident chronic kidney disease, chronic kidney disease progression and end-stage renal disease. However, the extent of proton pump inhibitor prescriptions to chronic kidney disease patients is still unclear. METHOD In a retrospective study, we enrolled patients (>18 years old) who received proton pump inhibitor in the out-patient setting from 2014 through 2015. All data was obtained from electronical medical records of Soonchunhyang Medical Center. The prescription patterns and characteristics of proton pump inhibitors were analyzed according to individual estimated glomerular filtration rate of the patients. RESULT During the study period 178,228 patients visited the out-patient clinic. Proton pump inhibitors were prescribed to 9,109 (5.11%) patients. In our sample, 50% were females and 9.8% were chronic kidney disease (eGFR<60mL/min/1.73 m2) patients. Among the patients with chronic kidney disease, 730 (8.0%) were categorized as stage 3 or 4 and 166 (1.8%) were categorized as stage 5 or end-stage renal disease. The prevalence of proton pump inhibitors prescription among chronic kidney disease patients was higher than in the non-chronic kidney disease group (p<0.001). Median duration of usage was 120 [interquartile range 63-273] days in the stage 3-4 group, 106 [56-266] days in the stage 5-end-stage renal disease group and 90 [56-176] days in the non-chronic kidney disease group. Patients in stage 3-4 group were prescribed longer duration of proton pump inhibitors than the non-chronic kidney disease group even after adjusting for age and sex (p<0.001). The main departments of medicine which prescribed proton pump inhibitors for the stage 3-4 group were gastroenterology (40.0%), cardiology (29.6%), nephrology (9.5%) and neurology (4.8%). Compared to the non-chronic kidney disease group, the stage 3-4 and stage 5-end-stage renal disease group were taking larger number of drugs simultaneously (6.90±4.17 vs4.54±2.43; p<0.001, 5.64±2.87 vs 4.54±2.34; p<0.001, respectively). CONCLUSION Chronic kidney disease patients are taking proton pump inhibitors for a much longer duration compared to non-chronic kidney disease patients. Physicians should pay careful attention when prescribing proton pump inhibitors to high risk groups.

Abstract
Aims Patients with chronic kidney disease (CKD) and Helicobacter pylori (H. pylori) infection have a higher incidence of gastroduodenal diseases and therefore are recommended to receive eradication therapies. This study aimed to assess the efficacy of a 7-day standard triple therapy in patients with CKD (eGFR < 60 ml/min/1.73 m2) and to investigate the clinical factors influencing the success of eradication. Methods A total of 758 patients with H. pylori infection receiving a 7-day standard first-line triple therapy between January 1, 2013, and December 31, 2014, were recruited. Patients were divided into two groups: CKD group (N = 130) and non-CKD group (N = 628). Results The eradication rates attained by the CKD and non-CKD groups were 85.4% and 85.7%, respectively, in the per-protocol analysis (p = 0.933). The eradication rate in CKD stage 3 was 84.5% (82/97), in stage 4 was 88.2% (15/17), and in those who received hemodialysis was 87.5% (14/16). There were no significant differences in the various stages of CKD (p = 0.982). The adverse events were similar between the two groups (3.1% versus 4.6%, p = 0.433). Compliance between the two groups was good (100.0% versus 99.8%, p = 0.649). There was no significant clinical factor influencing the H. pylori eradication rate in the non-CKD and CKD groups. Conclusions This study suggests that the H. pylori eradication rate and adverse rate in patients with CKD are comparable to those of non-CKD patients.

Abstract
Patients with chronic kidney disease (CKD) who had peptic ulcer bleeding (PUB) may have more adverse outcomes. This population-based cohort study aimed to identify risk factors that may influence the outcomes of patients with CKD and PUB after initial endoscopic hemostasis. Data from 1997 to 2008 were extracted from the National Health Insurance Research Database in Taiwan. We included a cohort dataset of 1 million randomly selected individuals and a dataset of patients with CKD who were alive in 2008. A total of 18,646 patients with PUB were screened, and 1229 patients admitted for PUB after endoscopic hemostasis were recruited. The subjects were divided into non-CKD (n = 1045) and CKD groups (n = 184). We analyzed the risks of peptic ulcer rebleeding, sepsis events, and mortality among in-hospital patients, and after discharge. Results showed that the rebleeding rates associated with repeat endoscopic therapy (11.96% vs 6.32%, P = 0.0062), death rates (8.7%, vs 2.3%, P < 0.0001), hospitalization cost (US$ 5595±7200 vs US$2408 ± 4703, P < 0.0001), and length of hospital stay (19.6 ± 18.3 vs 11.2 ± 13.1, P < 0.0001) in the CKD group were higher than those in the non-CKD group. The death rate in the CKD group was also higher than that in the non-CKD group after discharge. The independent risk factor for rebleeding during hospitalization was age (odds ratio [OR], 1.02; P = 0.0063), whereas risk factors for death were CKD (OR, 2.37; P = 0.0222), shock (OR, 2.99; P = 0.0098), and endotracheal intubation (OR, 5.31; P < 0.0001). The hazard ratio of rebleeding risk for aspirin users after discharge over a 10-year follow-up period was 0.68 (95% confidence interval [CI]: 0.45-0.95, P = 0.0223). On the other hand, old age (P < 0.0001), CKD (P = 0.0090), diabetes (P = 0.0470), and congestive heart failure (P = 0.0013) were the independent risk factors for death after discharge. In-hospital patients with CKD and PUB after endoscopic therapy had higher recurrent bleeding, infection, and mortality rates, and the need for second endoscopic therapy. Age was the independent risk factor for recurrent bleeding during hospitalization. After being discharged with a 10-year follow-up period, nonaspirin user was a significant factor for recurrent bleeding.

[PMID: 27449117 DOI: 10.1016/j.ejim.2016.06.035] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2016] [Revised: 06/29/2016] [Accepted: 06/29/2016] [Indexed: 01/10/2023]
Abstract
BACKGROUND End stage renal disease (ESRD) contributes to a higher mortality rate in peptic ulcer bleeding (PUB) patients. A crucial question is whether early Helicobacter pylori (H. pylori) eradication therapy is necessary for H. pylori-infected chronic kidney disease (CKD) patients. To explore whether H. pylori eradication therapy has a lower risk of PUB at the pre-ESRD stage than at the ESRD stage. METHODS AND PATIENTS Patients meeting 2 criteria were defined as newly diagnosed ESRD cases: (1) patients diagnosed with ESRD and receiving regular dialysis between 2000 and 2009; and (2) patients with no history of dialysis between 1997 and 1999. We divided the study participants into pre-ESRD and ESRD groups on the basis of the time between H. pylori eradication and dialysis. The date of the first PUB diagnosis was defined as the primary endpoint. Stratified Cox proportional hazard regression analysis was used to estimate the effect of H. pylori eradication at the pre-ESRD and ESRD stage on the occurrence of PUB. RESULTS We included 476 patients in the pre-ESRD cohort and 476 patients in the matched ESRD cohort. After adjustment for age, sex, the presence of comorbidities, and medication use, the hazard ratio of PUB was 0.66 times less in the pre-ESRD cohort than in the ESRD cohort. Factors such as Charlson's score more than 3, and nonsteroidal anti-inflammatory drugs were associated with an increased risk of PUB. CONCLUSION Our result supports that early H. pylori eradication has a lower risk of PUB in H. pylori-infected CKD patients.

Abstract
Background/Aims The connection between Helicobacter pylori and complicated peptic ulcer disease in peptic ulcer bleeding (PUB) patients taking nonsteroidal anti-inflammatory drugs has not been established. In this study, we sought to determine whether delayed H. pylori eradication therapy in PUB patients increases complicated recurrent peptic ulcers. Methods We identified inpatient PUB patients using the Taiwan National Health Insurance Research Database. We categorized patients into early (time lag ≤120 days after peptic ulcer diagnosis) and late H. pylori eradication therapy groups. The Cox proportional hazards model was used. The primary outcome was rehospitalization for patients with complicated recurrent peptic ulcers. Results Our data indicated that the late H. pylori eradication therapy group had a higher rate of complicated recurrent peptic ulcers (hazard ratio [HR], 1.52; p=0.006), with time lags of more than 120 days. However, our results indicated a similar risk of complicated recurrent peptic ulcers (HR, 1.20; p=0.275) in time lags of more than 1 year and (HR, 1.10; p=0.621) more than 2 years. Conclusions H. pylori eradication within 120 days was associated with decreased complicated recurrent peptic ulcers in patients with PUB. We recommend that H. pylori eradication should be conducted within 120 days in patients with PUB.

Abstract
The presence of concomitant diseases is an independent predictive factor for non-Helicobacter pylori (H. pylori) peptic ulcers. Patients contracting concomitant diseases have an increased risk of developing ulcer disease through pathogenic mechanisms distinct from those of H. pylori infections. Factors other than H. pylori seem critical in peptic ulcer recurrence in end stage renal disease (ESRD) and cirrhotic patients. However, early H. pylori eradication is associated with a reduced risk of recurrent complicated peptic ulcers in patients with ESRD and liver cirrhosis. Resistances to triple therapy are currently detected using culture-based and molecular methods. Culture susceptibility testing before first- or second-line therapy is unadvisable. Using highly effective empiric first-line and rescue regimens can yield acceptable results. Sequential therapy has been included in a recent consensus report as a valid first-line option for eradicating H. pylori in geographic regions with high clarithromycin resistance. Two novel eradication regimens, namely concomitant and hybrid therapy, have proven more effective in patients with dual- (clarithromycin- and metronidazole-) resistant H. pylori strains. We aim to review the prevalence of and eradication therapy for H. pylori infection in patients with ESRD and cirrhosis. Moreover, we summarized the updated H. pylori eradication regimens.

Abstract
End-stage renal disease (ESRD) patients exhibit an increased incidence of peptic ulcer disease. Helicobacter pylori plays a central role in the development of peptic ulcers. The effect of early H pylori eradication on the recurrence of complicated peptic ulcer disease in ESRD patients remains unclear. The aim of the present study was to explore whether early H pylori eradication therapy in ESRD patients can reduce the risk of recurrent complicated peptic ulcers.We conducted a population-based cohort study and recruited patients with ESRD who had developed peptic ulcers. We categorized patients into early (time lag ≦120 days after peptic ulcer diagnosis) and late H pylori eradication therapy groups. The Cox proportional hazards model was used. The endpoint was based on hospitalization for complicated recurrent peptic ulcers.The early and late H pylori eradication therapy groups consisted of 2406 and 1356 ESRD patients, respectively, in a time lag of 120 days. After adjusting for possible confounders, the early eradication group exhibited a lower rate of complicated recurrent peptic ulcer disease (hazard ratio [HR] = 0.76, 95% confidence interval [CI] = 0.64-0.91, P = 0.003) in a time lag of ≦120 days, but a similar rate of complicated recurrent peptic ulcer disease in time lags of ≦1 year (HR = 0.97, 95% CI 0.79-1.19, P = 0.758) and 2 years (HR = 1.11, 95% CI 0.86-1.44, P = 0.433) compared with the late eradication group.We recommend administering H pylori eradication within 120 days after peptic ulcer diagnosis to H pylori infected ESRD patients who have developed peptic ulcers.

Abstract
BACKGROUND AND OBJECTIVES Patients with CKD receiving maintenance dialysis are at risk for upper gastrointestinal bleeding. However, the risk of upper gastrointestinal bleeding in patients with early CKD who are not receiving dialysis is unknown. The hypothesis was that their risk of upper gastrointestinal bleeding is negatively linked to renal function. To test this hypothesis, the association between eGFR and risk of upper gastrointestinal bleeding in patients with stages 3-5 CKD who were not receiving dialysis was analyzed. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Patients with stages 3-5 CKD in the CKD program from 2003 to 2009 were enrolled and prospectively followed until December of 2012 to monitor the development of upper gastrointestinal bleeding. The risk of upper gastrointestinal bleeding was analyzed using competing-risks regression with time-varying covariates. RESULTS In total, 2968 patients with stages 3-5 CKD who were not receiving dialysis were followed for a median of 1.9 years. The incidence of upper gastrointestinal bleeding per 100 patient-years was 3.7 (95% confidence interval, 3.5 to 3.9) in patients with stage 3 CKD, 5.0 (95% confidence interval, 4.8 to 5.3) in patients with stage 4 CKD, and 13.9 (95% confidence interval, 13.1 to 14.8) in patients with stage 5 CKD. Higher eGFR was associated with a lower risk of upper gastrointestinal bleeding (P=0.03), with a subdistribution hazard ratio of 0.93 (95% confidence interval, 0.87 to 0.99) for every 5 ml/min per 1.73 m(2) higher eGFR. A history of upper gastrointestinal bleeding (P<0.001) and lower serum albumin (P=0.004) were independently associated with higher upper gastrointestinal bleeding risk. CONCLUSIONS In patients with CKD who are not receiving dialysis, lower renal function is associated with higher risk for upper gastrointestinal bleeding. The risk is higher in patients with previous upper gastrointestinal bleeding history and low serum albumin.

Abstract
BACKGROUND End stage renal disease (ESRD) patients receiving hemodialysis (HD) have a higher risk of peptic ulcer bleeding (PUB). AIMS Whether ESRD patients receiving peritoneal dialysis (PD) also carries a higher risk of PUB has not been studied. METHODS This was a cohort study using Taiwan's National Health Insurance research database, whereby 11,408 patients, including 2,239 PD, 2,328 HD, 2,267 chronic kidney disease (CKD) and 4,574 controls with age-sex matching were recruited. The log-rank test was used to analyze differences in accumulated PUB-free survival rates between groups. Cox proportional hazard regression was performed to evaluate independent risk factors for PUB in all the enrollees. RESULTS During the 7-year follow-up, PD and CKD patients had a significantly higher rate of PUB than matched controls. The risk of PUB between PD and CKD was not significantly different. Moreover, patients receiving HD carried a higher risk of PUB than those receiving PD, with CKD and controls (p all <0.05, by log-rank test). Cox proportional hazard regression analysis showed that CKD (HR 3.99, 95 % CI 2.24-7.13), PD (HR 3.71, 95 % CI 2.00-6.87) and HD (HR 11.96, 95 % CI 7.04-20.31) were independently associated with an increased risk of PUB. Being elderly, male, having hypertension, diabetes, cirrhosis, and nonsteroidal anti-inflammatory drugs and steroid use were other independent risk factors of PUB in all enrollees. CONCLUSIONS Patients with CKD and ESRD receiving PD or HD carried a higher risk for PUB. They should be screened for risk factors for PUB and receive some protective measures to prevent PUB.

Abstract
Background and Aims: Patients suffering from peptic ulcer (PU) bleeding who have end-stage renal disease (ESRD) may encounter more adverse outcomes. The primary objective is to investigate the risk factors that influence the outcomes of ESRD and chronic kidney disease (CKD) patients with PU bleeding after successful initial endoscopic haemostasis. Methods: A total of 540 patients with PU bleeding after initial endoscopic haemostasis in a tertiary hospital were investigated retrospectively. They were sorted into three groups after randomised age-matched adjustment: ESRD group (n = 90), CKD group (n = 90) and control group (n = 360). Main outcome measurements were rebleeding, requirement for blood transfusion and surgery, length of hospital stay and mortality. Results: The rebleeding rates were 43% for the ESRD group vs. 21% for the CKD group vs. 12% for the control group (overall p = < 0.001). Multivariate analysis showed the predictors of rebleeding were ESRD, time to endoscope, and non-high-dose proton-pump inhibitors (PPI) users. The risk factors for bleeding-related mortality were presence of moderate degree of CKD and ESRD group, time to endoscope, and Rockall score. All-cause mortality was related to presence of moderate degree of CKD and ESRD group, platelet count, time to endoscope, Rockall score and length of hospital stay. Conclusions: ESRD patients who suffered from PU bleeding were at risk of excessive rebleeding and mortality with frequent occurrence of delayed rebleeding. This study suggests that early endoscopy for initial haemostasis and high-dose intravenous PPI are associated with the reduction of rebleeding risk especially in patients with high Rockall scores.

Abstract
BACKGROUND Few large population-based studies have compared the incidence of bleeding of gastroduodenal ulcers between patients with and without end-stage renal disease. We investigated the association between ulcer bleeding and end-stage renal disease in patients receiving hemodialysis, and we sought to identify risk factors for ulcer bleeding. METHODS We performed a nationwide seven-year population study using data from the National Health Insurance Research Database in Taiwan. We identified 36 474 patients with end-stage renal disease who were receiving hemodialysis, 6320 patients with chronic kidney disease and 36 034 controls matched for age, sex and medication use. We performed log-rank testing to analyze differences in survival time without ulcer bleeding among the three groups. We performed Cox proportional hazard regressions to evaluate the risk factors for ulcer bleeding among the three groups and to identify risk factors in patients receiving hemodialysis. RESULTS Patients receiving hemodialysis and those with chronic kidney disease had a significantly higher incidence of ulcer bleeding than controls had (p<0.001). Hemodialysis (hazard ratio [HR] 5.24, 95% confidence interval [CI] 4.67-5.86) and chronic kidney disease (HR 1.95, 95% CI 1.62-2.35) were independently associated with an increased risk of ulcer bleeding. Diabetes mellitus, coronary artery disease, cirrhosis and use of nonsteroidal anti-inflammatory drugs were risk factors for ulcer bleeding in patients with end-stage renal disease who were receiving hemodialysis INTERPRETATION Patients with end-stage renal disease who are receiving hemodialysis had a high risk of ulcer bleeding. Diabetes mellitus, coronary artery disease, cirrhosis and the use of nonsteroidal anti-inflammatory drugs were important risk factors for ulcer bleeding in these patients.

Abstract
OBJECTIVES The aim of this study was to elucidate the impact of Helicobacter pylori infection on esophagogastroduodenal mucosal lesions in patients with end-stage renal failure on maintenance hemodialysis (HD). METHODS An upper endoscopy and the (13)C-urea breath test were performed in 198 patients on maintenance HD. Clinical features, serum pepsinogen levels and esophagogastroduodenal mucosal lesions were compared between H. pylori-positive and H. pylori-negative patients. Risk factors associated with esophagogastroduodenal mucosal lesion were determined by multivariate analyses. RESULTS The upper endoscopy revealed that gastric erosion was the most frequent (58%) type of esophagogastroduodenal mucosal lesion, followed by duodenal erosion (18%), gastric ulcer (14%), gastroesophageal reflux disease (10%), and duodenal ulcer (7%). Of the 198 patients enrolled in the study, 81 were positive and 117 patients were negative for H. pylori infection. The time duration after the introduction of HD was significantly longer and serum pepsinogen I/II ratio was significantly higher in H. pylori-negative patients than in H. pylori-positive patients. Multivariate analyses revealed that the H. pylori infection was an independent, protective factor for gastric erosion (odds ratio 0.38; 95% confidence interval 0.21-0.70), while the infection was unrelated to other mucosal lesions. CONCLUSIONS The most common mucosal lesion observed in our study cohort, all of whom were patients on maintenance HD, was gastric erosion. The high prevalence of this type of lesion may be explained partly by the cure of H. pylori infection during the clinical course of maintenance HD.

Abstract
The pathogenesis, incidence, complication rates, response to acid suppression and Helicobacter pylori (H. pylori) eradication therapy in peptic ulcer associated with chronic disease such as liver cirrhosis, chronic renal failure, diabetes mellitus, and critically ill conditions are different from those with general population, so that the management strategies also should be differentiated. The eradication of H. pylori are not so effective for preventing recurrence of peptic ulcer in liver cirrhosis patients as shown in general population, and conservative managements such as preventing deterioration of hepatic function and decrease in portal pressure are mandatory to reduce the risk of ulcer recurrence. The standard triple therapy for H. pylori eradication are as effective in chronic renal failure patients as in normal population, but the frequency of side effects of amoxicillin is higher in the patients not receiving dialysis therapy. Delay in eradication therapy until beginning of dialysis therapy or modification of eradication regimen should be considered in such cases. High prevalence of asymptomatic peptic ulcers and increased mortality in complicated peptic ulcer disease warrant regular endoscopic surveillance in diabetic patients, especially with angiopathy. The prolongation of duration of eradication therapy also should be considered in diabetic patients with angiopathic complication because of lower eradication rate with standard triple regimens as compared to normal population. Prophylactic acid suppressive therapy is highly recommended in critically ill patients with multiple risk factors. Herein, we propose evidence-based treatment guidelines for the management of peptic ulcer disease in special conditions based on literature review and experts opinion.

Abstract
The aim of this study is to evaluate the prevalence of GI symptoms, endoscopic abnormalities, histologic gastritis and Helicobacter pylori infection in children with End Stage Renal Disease (ESRD) undergoing maintenance hemodialysis. Upper endoscopy and gastric biopsy were performed in 31 consecutive ESRD children from 2002-2007, before renal transplantation. H. pylori status was determined by urease test and histology. The mean age of patients was 11 +/- 3.3 years (4-16 year). The mean duration of dialysis was 12.4 +/- 11 months (1.5-54 months). Seventeen patients (54.8%) were symptomatic. Twenty patients (64.5%) had endoscopic abnormalities. Antral erythema, esophagitis, antral nodularity and diffuse gastritis were common endoscopic findings. Endoscopic abnormalities were more common in symptomatic patients than asymptomatic patients (p < 0.05). Twenty patients (64.5%) were H. pylori positive. There was no statistical correlation between age, sex, serum creatinine level, presence of any symptoms and endoscopic abnormalities with H. pylori positivity. The mean duration of dialysis in H. pylori negative patients was significantly longer in comparison with H. pylori positive patients. High prevalence of eodoscopic abnormalities and H. pylori infection in both symptomatic and asymptomatic patients emphasize the necessity of upper GI evaluation in ESRD children before renal transplantation.

Abstract
Patients on hemodialysis often have gastrointestinal complications; however, it is unclear if Helicobacter pylori infection is present in these patients. Here we determined the prevalence of H. pylori infection in 539 Japanese hemodialysis patients by measuring serum anti-H. pylori IgG antibodies. Endoscopy was performed on 299 of these patients and the results were compared to 400 patients with normal renal function who had also undergone endoscopy and sero-testing. A second cohort of 478 dialysis patients, within the original group, was checked serologically for H. pylori infection three times over a four-year observation period. The prevalence of infection in these patients was significantly lower than in those patients with normal renal function, irrespective of the clinical outcomes. The prevalence of H. pylori infection significantly decreased as the duration of dialysis increased, particularly within the first four years following initiation of dialysis. About one-third of patients on dialysis for less than four years became serologically negative for H. pylori infection within this observation period. Our study suggests that although long-term dialysis patients have low prevalence of H. pylori, they still have significant gastroduodenal diseases, such as peptic ulcers, that require endoscopic follow-up.

Abstract
AIM Lesions of the gastrointestinal tract are frequent finding in uremic patients but their actual nature is not completely clear. The aim of this study was to detect any correlation between endoscopic lesions of patients with different levels of renal insufficiency. METHODS This prospective study involved 244 cases, with dyspeptic difficulties including 124 patients in different stages of renal insufficiency, and a control group of 120 patients with normal renal function. Upper esophagogastroscopy was performed in all patients because of the appearance of dyspeptic difficulties. Helicobacter pylori infection was detected by the urease test. RESULTS H. pylori infection (P=0.009), gastric erosions (P=0.019), gastric ulcer (P=0.002), and duodenal ulcer (P<0.001) were more common in the control group of patients. Significant negative correlations were found between the level of renal insufficiency and H. pylori infection (Kendall's tau=-0.346; P=0.003), stomach erosions (Kendall's tau=-0.272; P=0.019), stomach ulcer (Kendall's tau=-0.347; P=0.003), and duodenal ulcer (Kendall's tau=-0.531; P<0.001). CONCLUSIONS In patients with end stage renal disease, endoscopic lesions of the gastrointestinal tract are detected less frequently in relation to patients without kidney disease.

Abstract
BACKGROUND Upper gastrointestinal (UGI) symptoms are common in uremic patients, and higher serum levels of urea have been suggested to be related to Helicobacter pylori (HP) colonization and UGI mucosal inflammation. AIM The aim of this study was to compare HP infection and UGI endoscopic findings between uremic patients, renal transplant (RT) recipients, and controls. METHODS A total of 474 subjects (71 chronic renal failure [CRF], 73 hemodialysis [HD], 25 Tx, and 305 controls) from Baqyiatallah Hospital, Tehran, Iran were recruited between April 2002 and March 2004 for evaluation of dyspepsia, excluding those receiving any HP-eradication therapy. All subjects were examined for esophagus, stomach and duodenum mucosa, and infection with HP on 2 distinct tissue samples of the anthral region. RESULTS Four groups of subjects (mean +/- 2 se; age, 45 +/- 1.6 years; 62.9% male) were studied. Duodenal ulcer in the uremic patients (CRF, 16.1%; HD, 13.7%) was more common than that in the RT-recipients (8%) and controls (6.5%); P=.038. Erosive gastritis and duodenal bulb deformity were also more common in the uremic subjects (CRF, 23.9%, 36.9%; HD, 30.1%, 20.5%, respectively) than those in the other subjects (RT recipients, 16%, 8%; controls, 8.2%; 0%, respectively); P<.001. HP infection was found to be higher in the uremic patients (CRF, 66.2%; HD, 63%) than in the RT recipients (40%) and controls (34.8%); P<.001. CONCLUSION Higher rates of gastric and duodenal mucosal lesions and HP infection in the uremic patients in comparison with the subjects with normal renal function may have resulted from higher serum levels of urea, anemia, and fluctuations in the gastric blood supply in the CRF and HD patients. However, more tenable evidence from controlled trials is required for the eradication of HP in all uremic patients and transplantation candidates.

Abstract
BACKGROUND The role of Helicobacter pylori in the pathogenesis of peptic ulcer disease in patients with uraemia remains unclear. AIM To evaluate the long-term effect of H. pylori eradication in these patients. METHODS Uraemic and non-uraemic patients with peptic ulcer were enrolled in this study. Patients having history of non-steroidal anti-inflammatory drugs use or cardiovascular disease that need aspirin use were excluded. After confirmation of H. pylori infection, they received a triple therapy and were followed up for 2 years. RESULTS Between September 1999 and December 2005, 34 patients (41%) of the end-stage renal disease [H. pylori (+) group] and 67 (84%) of the non-uraemic patients with peptic ulcer disease (PU group) received anti-H. pylori therapy. After triple therapy, 32 (94%) from the end-stage renal disease group and 64 (96%) from the peptic ulcer group obtained successful eradication. During the 2-year follow-up, three patients in the end-stage renal disease group were excluded because of the presence of cardiovascular disease and aspirin use in two cases and died of heart failure in one case; two patients in peptic ulcer group refused follow-up. Finally, 29 uraemic and 62 non-uraemic patients had achieved the follow-up. Recurrence of peptic ulcer was more in the end-stage renal disease group than in the peptic ulcer group with intention-to-treat analysis (eight of 32, 25% vs. two of 64, 3%, P = 0.001, OR: 10.0, 95% CI: 1.979-50.540) or per-protocol analysis (eight of 29, 28% vs. two of 62, 3%, P < 0.001, OR: 11.4, 95% CI: 2.245-58.168). CONCLUSIONS Peptic ulcer recurrence after H. pylori eradication is higher in end-stage renal disease patients with peptic ulcer than in peptic ulcer patients without renal disease. Factors aside from H. pylori play an important role in peptic ulcer recurrence in end-stage renal disease patients.

Abstract
OBJECTIVES This study aimed to determine time trends in the frequency of endoscopic esophagitis, and Helicobacter pylori (H. pylori) infection in a large Singaporean teaching hospital over a 10-yr period. METHODS We studied a consecutive series of 16,375 patients who had been newly referred for diagnostic esophagogastroduodenoscopy from 1992 to 2001. All endoscopic findings were prospectively recorded. From 1995, an antral biopsy was taken from 6,185 unselected patients for an in-house biopsy urease test. Endoscopic esophagitis was defined as the presence of erosions and/or ulceration. The relationship between erosive esophagitis and various relevant factors was analyzed. RESULTS The overall prevalence of endoscopic esophagitis was 6.9% (95% CI, 6.5-7.3). It was 7.3% (95% CI, 6.2-8.4) in patients with a positive urease test, and 9.0% (95% CI, 8.1-9.9) in those in whom the urease test was negative (p < 0.001). From 1992 to 2001, the frequency of endoscopic esophagitis increased (p < 0.001 for trend) while that of positive urease test decreased from 1995 to 2001 (p < 0.001 for trend). The increase in the prevalence of endoscopic esophagitis (RR 1.99, 95% CI 1.18-3.36, p= 0.0098), and its inverse relationship with positive urease test results (RR 0.991, 95% CI 0.983-0.999, p= 0.049) remained significant even after adjusting for age, gender, ethnic distribution, and hiatal hernia. CONCLUSIONS The frequency of endoscopic esophagitis increased in Singapore from 1992 to 2001. This increase within a short period of time suggests that environmental factors, of which the decreasing rate of H. pylori infection may be one, are important in the pathogenesis of gastroesophageal reflux disease.

Abstract
BACKGROUND Patients with chronic renal failure (CRF) often have dyspeptic symptoms and may develop peptic disease or digestive disorders leading to severe gastrointestinal complications. The primary aim of this study was to evaluate the prevalence of peptic lesions and Helicobacter pylori infection, and the severity of dyspeptic symptoms, in dyspeptic patients with and without CRF. Our secondary aim was to investigate whether uremic status may affect the diagnostic efficiency of the [13]C-urea breath test ([13]C-UBT). PATIENTS AND METHODS We consecutively enrolled in the study 50 dyspeptic patients with chronic kidney failure (mean age 52 +/- 5 years), of whom 11 were on hemodialysis treatment (HD), and 93 subjects (mean age 54 +/- 7 years) with chronic dyspepsia and normal renal function (NRF). All patients completed an oriented and validated questionnaire scoring the severity of nine dyspeptic symptoms (i.e. epigastric pain, epigastric burning, postprandial fullness, early satiety, bloating, belching, nausea and vomiting) and underwent upper endoscopy with multiple bioptic sampling for rapid urease test and histological examination, [13]C-UBT and HpSA test. RESULTS The prevalences of peptic lesions and H. pylori infection and mean symptom score were 74%, 52% and 3.5 +/- 3, respectively, in dyspeptic patients with CRF and 18%, 36% and 8 +/- 5, respectively, in dyspeptic patients with NRF. The diagnostic accuracy of [13]C-UBT with respect to histological diagnosis was 94% and 97% for dyspeptic patients with and without renal failure, respectively. CONCLUSIONS 1, A high frequency of peptic lesions and low symptom scores were observed in uremic patients in spite of H. pylori infection; 2, uremic status did not affect the diagnostic accuracy of [13]C-UBT.

Abstract
AIM: To prospectively assess the sensitivity, specificity and time to positivity of theUltra-rapid urease test (URUT) for Helicobacter pylori (H pylori ), and compare the results of one with those of two biopsies.
METHODS: Five antral biopsies were taken in consecutive patients undergoing upper endoscopy: one and two biopsies for URUT, and one each for H pylori culture and histology. URUT was read at 1, 5, 10, 20 and 30 min, 1, 2, 3 and 24 h after biopsy insertion into the reagent. A positive histology and/or culture was used as positive reference ”gold standards”.
RESULTS: URUT was more sensitive for detecting H pylori with two biopsies rather than one, at all time points up to 120 min. The sensitivity improved from 3.6% to 82.1% for one biopsy and 10.7% to 85.7% for two biopsies from 1 to 120 min. The sensitivity reached 96.4% at 24 h for both, but the specificity reduced from 100% to 96% and 92% for one and two biopsies, respectively.
CONCLUSION: Development of a positive URUT result is hastened by doubling the number of gastric biopsies. We recommend taking two instead of one biopsy to achieve an earlier positive URUT result so that H pylori eradication therapy can be initiated before patient is discharged from the endoscopy suite.

Abstract
BACKGROUND AND AIMS To provide a direct comparison of Helicobacter pylori-positive subjects bleeding from duodenal ulcer with H. pylori-negative ones, in terms of severity of bleeding and outcome. PATIENTS AND METHODS A case-control study was prospectively conducted in 105 H. pylori-negative duodenal ulcer bleeders and same number of sex- and age-matched H. pylori-positive ones. RESULTS NSAID consumption was more common among H. pylori-negative subjects (81%) compared to their H. pylori-positive counterparts (58.1%, P < 0.001). H. pylori-negative bleeders were found to need more often haemostasis (55.2% versus 31.4%, P < 0.001) or surgical intervention (15.2% versus 4.8%, P = 0.011) and to have a greater proportion of rebleeding (32.4% versus 13.3%, P = 0.001), a more prolonged hospitalisation (11.6 +/- 4.1 versus 6.2 +/- 1.5 days, P < 0.001) and a higher rate of in-hospital mortality (15.2% versus 3.8%, P = 0.005). In the overall population (N = 210), H. pylori negativity, among other known risk factors, emerged as independent predictor (odds ratio: 3.2; 95% CI: 1.5, 11.2; P = 0.004) of an unfavourable outcome (surgery or death). CONCLUSIONS Duodenal ulcer bleeding in H. pylori-negative subjects appears to be more severe, to have a higher rate of rebleeding, and to lead more often to surgery or fatality compared to the vast majority of H. pylori-positive duodenal ulcer bleeders.

Abstract
BACKGROUND The efficacy of short-course triple therapy for the eradication of Helicobacter pylori has been documented in patients with normal renal function. We evaluated the efficacy and safety of a 1-week proton-pump inhibitor-based triple therapy for H pylori eradication in a prospective study of patients with chronic renal failure (CRF). METHODS Forty-two patients with a creatinine clearance (CrCl) less than 30 mL/min/1.73 m2 or serum creatinine level greater than 2.26 mg/dL (>200 micromol/L; n = 21; CRF group; 12 patients on dialysis therapy) or normal renal function (n = 21; controls) were studied when they had H pylori infection on top of peptic ulcer disease (20 patients) or gastritis (22 patients). The combination of omeprazole, 20 mg twice daily; amoxicillin, 1 g twice daily; and clarithromycin, 500 mg twice daily, was administered for 1 week. All patients underwent repeated endoscopy 4 weeks later for assessment of eradication. Apart from patients on dialysis therapy, all patients had serum creatinine levels and CrCls measured 2 and 4 weeks after treatment. RESULTS All except 5 patients (2 patients, CRF group; 3 controls) had successful eradication (90.5% versus 85.7%). For patients not on dialysis therapy, serum creatinine levels and CrCls remained stable 4 weeks after treatment (serum creatinine, 3.68 +/- 1.09 versus 3.76 +/- 1.09 mg/dL [325 +/- 96 versus 332 +/- 96 micromol/L]; P = not significant [NS]; CrCl, 21.4 +/- 8.3 versus 22.2 +/- 6.9 mL/min/1.73 m2; P = NS). CONCLUSION The 1-week course of proton-pump inhibitor-based triple therapy achieved a high eradication rate of H pylori infection in patients with CRF, similar to controls with normal renal function. The regimen was well tolerated.
