Abstract
Objective Chronic kidney disease (CKD) affects gastrointestinal system (GIS) and causes histological, functional and mucosal changes. There are scarce data investigating GIS symptoms and findings in patients with CKD stage III-V, receiving hemodialysis (HD) and peritoneal dialysis (PD). In this study, we aimed to evaluate the frequency of gastrointestinal symptoms and findings and compare between renal replacement therapies. Method A total of 290 patients (97 in CKD stage III-V, 92 PD, 101 HD) were included in this study. Gastrointestinal complaints, diseases, background characteristics of patients and drugs they used were questioned by interviews, forms were filled and examinations of patients were performed. Results of upper GIS endoscopy, colonoscopy, abdominal ultrasonography and tomography of patients were evaluated. Results The most common signs were dyspepsia (50%), nausea (45%) and epigastric pain (44%) among all patients, generally. Gastrointestinal disorders like gastritis (62%) and gastroesophageal reflux (39%) were frequent in patients. Prevalence of patients with weight loss was 20% in predialysis and 8% in PD and the ratio was higher in predialysis group statistically significantly (p = 0,016). The prevalence of gastritis was 70% in PD, 55% in HD and the prevalence of hemorrhoids was 24% in PD and 12% in HD. The prevalence of gastritis and hemorrhoids was higher in the PD group than in the HD group statistically significantly (p = 0.043, p = 0.028), otherwise, there wasn’t a difference between the PD and predialysis groups, statistically significantly. Conclusion This study showed that; gastrointestinal symptoms and disorders were very common in CKD, besides this; while gastritis and hemorrhoids were more frequent in the PD, esophagitis and hiatal hernia were more frequent in the HD.

Abstract
Background Dyspepsia is a common disorder in kidney transplant recipients, and the risk of post-transplant complications is increased in candidates with upper gastrointestinal disease. We evaluated gastrointestinal lesions of kidney transplant candidates on dialysis. Methods In this study, endoscopic and pathological findings in hemodialysis (HD) and peritoneal dialysis (PD) patients with gastrointestinal symptoms on the waiting list were compared. Results The most common non-ulcerous lesions in the endoscopic examination were gastritis (62.3%), erosive gastritis (38.7%), duodenal erosion or duodenitis (18.9%) and esophagitis (13.2%). The ulcerous lesion was present in only 3 patients. Gastroesophageal reflux disease, ulcerated lesion and non-ulcerated lesion rates were similar in both dialysis groups. Histopathological examination revealed Helicobacter pylori (HP) positivity in 28.3% of patients. HP positivity rate was significantly higher in PD patients than in HD patients (38.7% vs. 13.6%, p = 0.046). Chronic gastritis (75.5%) was the most common pathological finding. HP positivity rate was 37.5% in patients with chronic gastritis, but HP was negative in patients without chronic gastritis. In multivariate analysis, male gender, urea and albumin levels were associated with the presence of pathological chronic gastritis. The presence of gastritis, total cholesterol and ferritin levels were found significant for HP positivity. A total cholesterol > 243 mg/dL was significantly related to an increased risk of the presence of HP positivity. Conclusions Gastrointestinal lesions and HP infection are common in dialysis patients. Dialysis modality may affect the frequency of some lesions. It may be useful to have an endoscopic examination before entering the transplant waiting list for all candidates.

Abstract
Upper gastrointestinal (GI) abnormality is believed to be higher in patients with end-stage renal disease (ESRD) which can make a big trouble for whom undergo kidney transplant. We conducted this study to assess upper GI findings of patients with ESRD. In the present retrospective study we recorded upper GI endoscopy results in hemodialysis patients who were candidate for renal transplantation during a 10-year period. We reviewed files of 1256 patients with a mean age of 37.6 ± 13.4 years. Half of patients (50.6%) had an abnormal endoscopy. Two most common abnormalities were mild gastritis (35.6%) and gastro-esophageal reflux disease (16.7%). GI ulcers were observed in 11% of patients. Duodenal ulcer was the most common ulcer which was seen in 6.8% of patients. Helicobacter pylori was positive in 32.9% of patients and correlated with GI lesions (P = 0.000, r = 0.371). Longer dialysis duration and older patients revealed more upper GI abnormality (P = 0 .032, <0.001). As long as more than half of our patients have at least one upper GI involvement, we recommended that endoscopy must be done as a pretransplantation evaluation for patients without symptoms who have risk factors for ulcers.

Abstract
BACKGROUND/AIMS Duodenitis is not infrequent finding in patient undergoing endoscopy. However, hospitalized patients have a higher incidence of secondary duodenal mucosal lesions that might be related with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infection, tuberculosis, immunologic disorders, or other rare infections. We aimed to identify clinicopathologic features of duodenal mucosal lesions in hospitalized patients. METHODS All hospitalized patients having duodenal mucosal lesions were identified by endoscopic registration data and pathologic data query from 2011 to 2014. The diagnostic index was designed to be sensitive; however, a detailed review of medical record and endoscopic findings was undertaken to improve specificity. Secondary duodenal lesion was defined as having specific reason to explain the duodenal lesion. RESULTS Among 6,334 hospitalized patients have undergone upper endoscopy, endoscopic duodenal mucosal lesions was detected in 475 patients. Secondary duodenal lesions was 21 patients (4.4%) and the most frequent secondary cause was IBD (n = 7). The mean age of secondary group was significantly lower than that in primary group (42.3 ± 18.9 years vs. 58.5 ± 16.8 years, p = 0.00), and nonsteroidal anti-inflammatory drugs were less frequently used in secondary group, but there was no differences of gender or presence of Helicobacter pylori. The involvement of distal part of duodenum including postbulbitis or panduodenitis was more frequently detected in secondary group than in primary group. By multivariate regression analysis, younger age of 29 years and the disease extent were significant predictors for the secondary mucosal lesions. CONCLUSIONS Secondary duodenal mucosal lesions with different pathophysiology, such as IBD or CMV infection, are rare. Disease extent and age seems the most distinctive feature of secondary duodenal mucosal lesions.

Abstract
BACKGROUND AND STUDY AIMS Small intestinal pathology in hemodialysis (HD) patients has been studied in only a small number of retrospective case series. One method for noninvasively surveying small intestinal disorders is video capsule endoscopy (VCE). The primary aim of this study was to investigate the prevalence of small intestinal abnormalities among asymptomatic maintenance HD outpatients using VCE. The secondary aim was to assess the clinical impact of these abnormalities. PATIENTS AND METHODS This study consisted of two phases. In phase I, a cross-sectional study, a cohort of patients who received maintenance HD three times weekly at an outpatient hemodialysis clinic were studied using VCE. Phase II was a prospective cohort study with follow up for 1 year after VCE. RESULTS Fifty-six patients were enrolled in this study, and two were excluded from analysis due to capsule retention in the stomach. The prevalence of small bowel abnormalities in HD patients was 64.8 % (35/54) (95 % confidential interval 52.1 % - 77.6 %). Of 54 patients, 21 (38.9 %) had mucosal lesions, 10 (18.5 %) had vascular lesions, and 4 (7.4 %) had both lesion types. During the 1-year follow-up period, events occurred in four patients. A small bowel-associated event was observed in one patient, who underwent laparoscopy-assisted small intestinal partial resection 3 months after diagnosis by VCE. All patients in whom events were seen had small bowel abnormalities; no events were observed in the VCE-negative group. CONCLUSIONS Although asymptomatic maintenance HD patients had a high prevalence of small bowel abnormalities (64.8 %), they did not have a high incidence of small bowel-associated events during the 1-year follow-up.

Abstract
Chronic infection known to be a predisposing factor for the development of atherosclerosis. Several studies have found a possible role of Helicobacter pylori in the pathogenesis of atherosclerosis. The aim of this study was to investigate the presence of H. pylori in atherosclerotic plaques in iliac arteries in 25 end stage renal disease (ESRD) patients undergoing kidney transplantation. Esophagogastroduodenoscopy was performed in all patients before transplantation. Biopsy specimens obtained from gastric antrum were sent for pathologic evaluation. Gastric H. pylori infection was confirmed by microscopic assessment and rapid urease test. Arterial specimens were obtained from iliac arteries during kidney transplantation. Presence of H. pylori DNA in atherosclerotic plaques and healthy vessel samples was evaluated by the polymerase chain reaction (PCR). The mean age of patients was 44.1 ± 22.6 years. Risk factors in patients with atherosclerosis were hypertension (68%), diabetes mellitus (20%), hyperlipidemia (20%), positive family history (16%). Atherosclerotic plaques were found in 21 (84%) patients. PCR analysis did not detect H. pylori in any case. There was a significant relationship of atherosclerosis with hypertension (P = 0.006) but not with diabetes mellitus and hyperlipidemia (P = 0.5). There was no significant relationship between atherosclerosis and gastric H. pylori infection (P = 0.6). This study revealed no association between the presence of H. pylori as a pathogen of vessel walls and atherosclerosis in ESRD.

Abstract
BACKGROUND This study aimed to investigate the dyspeptic symptoms, endoscopic findings, and frequency of Helicobacter pylori (Hp) infection in children with chronic kidney disease (CKD) stage V, and to compare findings in peritoneal dialysis (PD) and hemodialysis (HD) patients. METHODS Sixty-five patients on PD (n = 36) or HD (n = 29) were included. Age, gender, duration and type of dialysis, and dyspeptic complaints were recorded. All patients underwent endoscopy. Rapid urease tests were performed in all patients and antral biopsy examinations done in suitable patients to investigate presence of Hp infection. RESULTS The mean age of patients (55 % male) was 13.9 ± 3.6 years. Frequency of dyspepsia was 43 % and was similar in HD and PD groups. The most frequent dyspeptic symptoms were early satiety (21.5 %) and bloating (17 %). Abnormal endoscopic findings were present in 81.5 % of patients (similar in both groups), and the most common lesion was gastritis (35.5 %). Hp positivity was determined in 37 % of the patients, which was similar in both groups. No significant relationship was found between dyspeptic symptoms and Hp infection. Hp infection was found to be significantly higher in 41.5 % of the patients with gastroduodenal lesions. Abnormal endoscopic findings were significantly higher in severely dyspeptic patients (88.9 %). CONCLUSIONS We think performing an upper gastrointestinal tract examination and Hp screening may be helpful in renal transplant candidates with severe dyspeptic symptoms.

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
The endoscopic appearance of duodenitis is a common finding in patients undergoing endoscopy because of epigastric pain however, the relationship of the visual findings to histology is poorly defined. We set out to ascertain if there was a correlation between the endoscopic and histological appearances of the duodenal mucosa. Consecutive patients with epigastric pain referred for diagnostic gastroduodenoscopy were studied. The visual appearances of 'duodenitis' (erythema, erosions and sub-epithelial haemorrhage) were reported independently by two endoscopists. Duodenal biopsies were taken and assessed for: neutrophil infiltrate, mononuclear infiltrate, gastric metaplasia, villous atrophy and a breach in the mucosa. H pylori status was determined. Of the 93 patients with endoscopic features of duodenitis an increase in histological markers of inflammation was found in 75 (81%). However, histological inflammation was absent or minimal in 68 (73%). Conversely, biopsies from normal-looking mucosa revealed histological evidence of inflammation in 26 (27%). For patients with the endoscopic features of duodenitis the positive & negative predictive value for neutrophilic infiltrate was 39% and 98% respectively. Biopsies from erosions confirmed a breach in the mucosa in only 2 of 40 patients. Neutrophilic infiltrate occurred with NSAI ingestion and infection with H pylori. The endoscopic appearance of the duodenal mucosa is unreliable in determining the presence of histological inflammation. The endoscopic appearance of 'erosions' is not usually associated with a mucosal breach.

Abstract
Chronic renal failure patients receiving hemodialysis and continuous ambulatory peritoneal dialysis often encounter gastrointestinal troubles over their long treatment period. Helicobacter pylori infection has close association with development of peptic ulcer, gastric cancer and gastric lymphoma, and is thought to be one of the major risk factors for gastrointestinal troubles in dialysis patients. However, it is unclear whether H. pylori infection is directly associated with progression of renal dysfunction and prognosis of chronic renal failure patients. Recent consensus shows that the prevalence of H. pylori infection in chronic renal failure patients is significantly lower than in subjects with normal renal function. In the natural history of H. pylori infection in hemodialysis patients, the prevalence of infection decreases as dialysis periods progressed, in particular within the first four years after the start of treatment. However, the chance of natural eradication becomes rare for patients receiving dialysis treatment for a long time. Moreover, chronic renal failure patients with H. pylori infection have a higher incidence of gastroduodenal diseases, and therefore, are recommended to receive eradication therapies, especially for those receiving treatment for a long time and with higher risks of complication. Intensive endoscopic check-ups for the prevention of gastrointestinal events and the discovery of peptic ulcer and neoplastic diseases at an early phase may be required.

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
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
BACKGROUND Peptic ulcers due to nonsteroidal anti-inflammatory drug (NSAID) use may have contributed to the static prevalence of ulcer disease in Asia. GOAL We aimed to determine the current etiology of peptic ulcer disease in Singapore. STUDY Consecutive patients undergoing esophagogastroduodenoscopy who had not been exposed to antibiotics, or antiulcer therapy within the past 6 months, and in whom peptic ulcers were found, were prospectively studied. Before endoscopy, patients were interviewed regarding the use of NSAID or aspirin. During endoscopy, antral biopsies were obtained for urease test and histology. Serum thromboxane B2 levels were compared with those of healthy volunteers. RESULTS Peptic ulcers were detected in 600 patients during a 2-year period. The ulcers were negative for Helicobacter pylori in 212 patients (35.3%) and these H. pylori negative ulcers were related to NSAID use in 68.9% of cases. On the basis of serum thromboxane B2 levels, 30.8% of the patients with non-H. pylori non-NSAID were considered to have consumed NSAID. CONCLUSIONS H. pylori negative peptic ulcer makes up a significant proportion of peptic ulcer in Singapore. Most of these ulcers were related to NSAID use. Serum thromboxane profile suggested surreptitious NSAID use in many of the non-H. pylori and apparently non-NSAID patients.

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
Patients with chronic renal failure are predisposed to infections. Infections in end-stage renal disease patients are caused by immunosuppressive effects of uremia. Patients with renal failure on dialysis have impaired host defenses and may develop infections related to vascular access. This article reviews the infectious complications related to chronic renal failure in dialysis.

Abstract
Over a three year period, 98 patients of moderate to severe chronic renal failure (S creatinine > 5 mg/dl) admitted in our centre were evaluated for upper GI lesions. All patients underwent upper GI endoscopy. In 68% upper GI mucosa was affected. Various lesions encountered were gastritis (25.5%), duodenitis (10.2%), gastroduodenitis (21.4%), telengiectasia (5.1%), and peptic ulcer in 6.1%. In 74 patients three biopsies, one each from antrum, fundus and duodenum were taken. 45.9% of these had chronic gastritis and 14.8% chronic duodenitis. Prevalence of H pylori on histology was 17.56%. 20 patients (9.6%) developed upper GI bleed during hospitalisation. In 17 (85%) patients, where endoscopy could be done, gastritis/duodenitis/oesophagitis were the common underlying lesions.

Abstract
AIMS To determine: (i) the prevalence of histological gastritis and peptic ulcer; and (ii) the clinical features of peptic ulcer, in patients with end-stage renal failure. METHODS Upper endoscopy was performed by a single observer in 268 patients with end-stage renal failure over a 6-year period. Gastric histology and Helicobacter pylori status were studied in 40 consecutive subjects in whom there were no contraindications for gastric biopsy and who had not used antibacterial drugs in the preceding 4 weeks. As there are only limited data for healthy volunteers in Singapore, 33 age-, sex- and race-matched patients with functional dyspepsia from an earlier drug trial and 18 healthy volunteers who were not age-matched were used as controls. The clinical features of 43 consecutive uraemic patients with peptic ulcer were compared with those of 118 consecutive non-uraemic peptic ulcer patients seen by the same author. RESULTS Among uraemic patients, histological gastritis was less common, compared with healthy volunteers and functional dyspepsia patients. Helicobacter pylori infection as assessed by histology was also less common among uraemic patients compared with functional dyspepsia patients, but the difference was not statistically significant on serological assessment. Uraemic patients with ulcer had an equal sex ratio, in contrast to a male preponderance among peptic ulcer patients with normal renal function. Uraemic patients with ulcer were more likely to be pain-free, to present with haemorrhage, to have multiple ulcers and postbulbar duodenal ulcers, but were less likely to have H. pylori infection. Among uraemic subjects, the prevalence of H. pylori infection was similar whether or not peptic ulcer was present. CONCLUSIONS The prevalence of histological gastritis was lower in uraemic patients when compared with patients with functional dyspepsia and healthy volunteers. Peptic ulcers in uraemic subjects have different clinical characteristics from peptic ulcer in non-uraemic subjects.

Abstract
Fifty patients with chronic renal failure and 50 asymptomatic healthy volunteers were studied to determine the prevalence of Helicobacter pylori in the two groups and to compare the results of ultrarapid urease test (URUT) and gastric histology for detecting H. pylori infection. Four gastric antral biopsy specimens were taken. Two specimens were used for the URUT and two were processed routinely. Sections were stained with H&E and Loeffler's methylene blue. Histological examination showed presence of H. pylori in 56% of patients with chronic renal failure (CRF) and in 78% of the controls. The difference was statistically significant (p < 0.05). The URUT was positive in only 16% of patients with CRF compared to 74% in the controls (p < 0.0001). The sensitivity and overall diagnostic accuracy of the URUT to diagnose H. pylori infection were 94.8 and 96%, respectively, in controls but were only 29 and 60%, respectively, in patients with CRF. It is concluded that the prevalence of H. pylori is significantly less in patients with CRF and that the URUT is less sensitive than gastric histology for diagnosing H. pylori infection in these patients.

Abstract
ESRD has well-documented effects on the esophagus, stomach, duodenum, and pancreas. Unless the supply of donor kidneys increases dramatically, these complications of ESRD will continue to be an important clinical issue for gastroenterologists given the large percentage of patients with symptoms. Further study of uremic retention products and abnormal gastrointestinal hormone profiles on the gastrointestinal tract should help provide additional insights into this complex group of patients.

Abstract
In the present double-blind placebo-controlled study the effect of cisapride on functional dyspepsia was evaluated in patients with and without histological gastritis. Patients with functional dyspepsia and whose symptoms persisted after a 2 week run-in period with antacid treatment were randomized to receive cisapride (10 mg) or matching placebo three times daily for 4 weeks. Symptoms of epigastric pain, bloating, nausea, belching, early satiety and heartburn were graded on a four-point scale based on patients' feedback and diary card recording. A global response was also formulated by the investigators. One hundred and four patients entered the study and 76 completed the trial, comprising 36 patients with histological gastritis and 40 patients without gastritis. Symptom scores in both gastritis and non-gastritis groups were significantly improved by both cisapride and placebo; however, the improvement was not statistically different between the two treatment groups. Cisapride produced a good or better global response in 58% of subjects with histological gastritis and in 53% of subjects without gastritis compared with 47% and 52%, respectively, of patients on placebo; this difference was not statistically significant. Gastric histology did not influence the effect of cisapride on the symptoms of functional dyspepsia.

Abstract
Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia, nausea and vomiting in patients with CRF. Specific pharmacological and nutritional interventions should thus be considered for the treatment of vomiting and feeding problems in CRF.

Abstract
Forty patients with chronic renal failure (CRF) were enrolled in this study. Twelve of the 40 patients had upper gastrointestinal symptoms or signs (GI Sx). Twenty of the 40 patients had been receiving regular haemodialysis (HD) for at least 1 year prior to the study. Radionuclide-labelled solid meals were used to calculate gastric emptying times (GETs). The carbon-14 urea breath test (14C4-UBT) was used to diagnose Helicobacter pylori (HP) infection. Among the 40 patients, 35 (88%) had an abnormal GET and 22 (55%) had a positive 14C-UBT for HP infection. There were no statistically significant differences in the incidence of abnormal GET among patients with HP infection and patients without HP infection. There were also no significant differences in the incidence of HP infection among patients with abnormal and normal GETs. In addition, the incidences of abnormal GET in patients with and without upper GI Sx were 83% and 89% respectively. The incidences of HP infection in patients with and without upper GI Sx were 58% and 54%, respectively. The incidences of abnormal GET in HD and non-HD patients were 95% and 80%, respectively. The incidences of HP infection in HD and non-HD patients were 45% and 65%, respectively. The differences in the incidences of abnormal GET and HP infection among HD and non-HD patients, as well as among patients with and without upper GI Sx, were not statistically significant.

Abstract
The objective of the study was to evaluate the prevalence of Helicobacter pylori in patients with different degrees of renal function. Two hundred and twenty consecutive patients requiring gastroscopy for upper intestinal symptoms were enrolled in the study: group I (normal renal function, n = 127), group II (chronic renal failure, creatinine clearance > 5 < 90 ml/min, n = 59), and group III (hemodialysis therapy, n = 34). On endoscopy, biopsy specimens were taken for analysis of H. pylori infection by urease test and histology. The prevalence of H. pylori in patients with renal dysfunction proved to be significantly lower than that in patients with normal renal function (22.6% vs 37%, P < 0.05). The incidence of ulcer disease in patients with normal renal function was higher than that in uremic patients (14.2% vs 10.8%, not significant). These findings indicate that uremic patients seem to be partly protected against H. pylori infection.

Abstract
The aim of this work was to assess gastric acid secretion in relation to morphological and histological changes in the gastric mucosa as well as prevalence of Helicobacter pylori in chronically haemodialyzed uraemic patients. Exocrine pancreatic functions after secretin-cerulein test were also studied. In haemodialyzed patients low basal gastric acid output was found, whereas peak output after pentagastrin stimulation did not differ significantly when compared to controls. Endoscopy of gastric and duodenal mucosa revealed inflammatory changes in the majority of patients, described histologically as chronic gastritis with duodenitis. Helicobacter pylori antigen was detected in the serum of 45% of uraemic patients. Serum amylase activity was elevated in haemodialyzed patients relative to controls. Although clinically asymptomatic, haemodialyzed patients exhibited various degrees of gastrointestinal mucosal abnormalities and impairment in exocrine pancreatic functions, mainly low stimulated bicarbonate and protein output as well as low electrolyte concentrations in duodenal content.

Abstract
Capsaicin, the pungent ingredient of chili, has a gastroprotective effect against experimental gastric mucosal injury in animals. Such an effect has not, however, been documented in humans to date. Eighteen healthy volunteers with normal index endoscopies underwent two studies four weeks apart. Each subject took 20 g chili orally with 200 ml water in one study and 200 ml water in another study. In each case this was followed half an hour later by 600 mg aspirin BP with 200 ml water. Endoscopy was repeated 6 hr later. Gastroduodenal mucosal damage was assessed by a previously validated scoring system. The median gastric injury score after chili was 1.5 compared to 4 in the control group (P < 0.05), demonstrating a gastroprotective effect of chili in human subjects.

Abstract
The pathogenesis of peptic ulceration is not yet clear. It could be due to an imbalance between acid secretion and mucosal defensive and/or protective mechanisms, but the association between Helicobacter pylori and peptic ulceration has questioned this hypothesis. Therefore, drugs inhibiting acid secretion and/or eradicating H. pylori are of major interest. Peptic ulcer disease is often associated with renal failure. For the selection of the proper dosage of these agents their pharmacokinetic properties and alterations in pharmacokinetics in various disease states, including renal failure, should be known. As histamine H2-receptor antagonists and pirenzepine are mainly eliminated by the renal route their elimination is dependent on creatinine clearance. Consequently, their elimination will be impaired in patients with renal insufficiency, which makes dosage reduction mandatory in these patients. No dosage supplementation is necessary after any type of dialysis because the drugs are removed in insignificant amounts by the various blood purification procedures. Misoprostol and proton pump inhibitors, such as omeprazole, lansoprazole and pantoprazole, are primarily eliminated by nonrenal routes. Therefore no dosage adjustments are necessary in patients with renal insufficiency. Bismuth salts, sucralfate and antacids should be avoided in patients with renal failure because of the accumulation of their cations and the associated risk of toxic reactions. For most agents more long term experience from comparative and double-blinded studies is needed to define better their clinical efficacy and tolerability in patients with renal failure.

Abstract
To determine the significance of the endoscopic classification of gastritis proposed by a working party at the World Congress of Gastroenterology in Sydney 1990, 167 patients undergoing upper alimentary endoscopy were prospectively assessed by comprehensive endoscopic and histological methods. Ninety eight patients had endoscopic mucosal changes of gastritis according to the Sydney classification. Twenty six (27%) of these had histologically normal biopsy specimens. This was not statistically significantly different to the 26 (38%) of 69 with normal endoscopies whose biopsy specimens were histologically normal (chi 2 = 1.857, p > 0.1). Forty three (62.5%) patients with normal endoscopies had histological gastritis. No histological counterpart was found for the macroscopic appearances of the gastric mucosa said to show inflammation proposed by the Sydney classification of gastritis. These findings confirm the inappropriateness of an endoscopic diagnosis of gastritis and it is suggested such a term should be reserved for the histological findings.

Abstract
The prevalence of peptic ulcer in cirrhotic patients is similar to that reported for the general population. Although gastric acid outputs ar normal or lower in cirrhotic subjects compared with non-cirrhotics, the frequency of non-response to histamine H2-receptor antagonists is higher. Peptic ulcer disease in the cirrhotic seems to pursue a more virulent course compared with that in the non-cirrhotic subject. Peptic ulcer prevalences in patients dying of uraemia or in uraemic patients on maintenance dialysis treatment are comparable with those in the general population. However, the frequency of peptic ulcer, especially complicated ulcer, is increased following renal transplantation. Ulcer complications in this context are associated with a high mortality rate. Pre-transplant risk factors for subsequent development of peptic ulcer remain to be identified and the value of histamine H2-receptor antagonists in prophylaxis is as yet unproven.

Abstract
Forty-eight patients with recurrent abdominal pain were studied endoscopically for the presence of gastritis and Helicobacter pylori infection. Fifteen of these children had histological evidence of gastritis with eight of them having concomitant H. pylori infection. The majority of those with H. pylori infection had severe degrees of acute following chronic gastritis.

Abstract
Gastrointestinal mucosal abnormalities ranging from edema to ulceration occur in two thirds of patients dying of uremia. Early studies suggested that uremic patients on maintenance dialysis treatment were at increased risk of peptic ulceration but more recent data indicate that this is not so. Other gastrointestinal problems reported for uremic subjects on maintenance dialysis treatment include bleeding from telangiectatic lesions, constipation, mucosal deposition of amyloid and acute pancreatitis. Nausea and vomiting are common in the uremic patient but gastric emptying studies have yielded conflicting results. Patients undergoing renal transplantation are at increased risk of development of esophagitis, complicated peptic ulcer, intestinal ulceration, and perforation as well as acute pancreatitis.

Abstract
Two urease-based tests--the urease slide test and the radiolabeled urea breath test, are commonly used for the diagnosis of Helicobacter pylori infection of the stomach. The reliability of these tests in chronic uremia was compared with serological tests for H pylori antibodies, and with direct detection of the organism by microscopy or culture of gastric antral biopsies. Twenty-seven patients with chronic renal failure and dyspepsia underwent upper gastrointestinal endoscopy. Twelve of these patients (46%) were judged to be infected with H pylori on the basis of identification of the organism on microscopy or culture of antral biopsy. Both urease-based tests were able to determine H pylori status, despite the markedly increased concentrations of urea in the gastric juice found in chronic renal failure. The urease slide test performed on antral biopsies obtained at endoscopy proved reliable in determining H pylori status with no false-positive nor false-negative results after 20 minutes and 24 hours of incubation. The 14C-urea breath test also differentiated the infected from the uninfected patients. The 20-minute 14CO2 excretion (kg %dose/mmol CO2 x 100) ranged from 50 to 834 in the H pylori-infected patients, compared with 0.3 to 27 in the H pylori-noninfected patients (P < 0.0001); the 90-minute values ranged from 88 to 398 in the former, compared with 1 to 79 in the latter (P < 0.0001). The excretion of 14CO2 (derived from bacterial hydrolysis of ingested 14C-urea) was higher in all the uremic patients compared with nonuremic controls, and in half of the H pylori-noninfected uremic patients there was a late increase in 14CO2 excretion.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This study aimed to examine the association between Helicobacter pylori, histological gastritis, and intestinal metaplasia in gastric cancers of different histological types. A total of 169 gastrectomy specimens received in one pathology department were studied. Altogether 156 were adenocarcinomas (intestinal type 87, diffuse type 50, mixed type 19). Gastritis occurred in 137 of 163 body specimens (84%) and in 126 of 131 antral specimens (96%). Its presence was unrelated to tumour histology. Atrophic gastritis was more common in both body and antral mucosa in intestinal type compared with diffuse type carcinoma. This was also true for intestinal metaplasia of the body, but not of the antral mucosa. H pylori was present in 101 of 163 (62%) body specimens and 56 of 131 (43%) antral specimens. In intestinal type carcinoma, H pylori was found in 52/84 (62%) body specimens and in 24/70 (34%) antral specimens, while the corresponding figures for diffuse type carcinoma were 29/48 (60%) and 17/38 (45%) respectively. Tumour histology therefore had no influence on the occurrence of H pylori. Tumour site had no effect on the presence or absence of gastritis, atrophic changes, intestinal metaplasia, or H pylori. While both H pylori and gastritis are associated with gastric cancer, the association is unrelated to tumour histology and may not be a causal one.

Abstract
AIMS To study the expression of HLA-DR antigen in the different histological types of gastric polyps. METHODS Ninety five cases of gastric polyps were histologically classified and examined for the presence of Helicobacter pylori, and for degree and type of inflammation. Further sections were stained immunohistochemically for HLA-DR antigen expression in the epithelium using a monoclonal antibody that was reactive to formalin-fixed paraffin wax embedded tissue. RESULTS HLA-DR antigen was expressed in all of the inflammatory polyps studied (20/20), and in most hyperplastic (12/16) and adenomatous (4/6) polyps. Only a few fundic gland polyps (8/51) stained positively for HLA-DR antigen. Gastric polyps seem to have a greater tendency to express HLA-DR antigens than non-polypoid gastric mucosa, even after considering the factors that may affect HLA-DR antigen expression, such as inflammation and the presence of H pylori. CONCLUSIONS Growth disturbances/polyp formation may be associated with increased HLA-DR antigen expression.

Abstract
AIMS To assess the association between Helicobacter pylori-associated gastritis and HLA-DR antigen (class II antigen) expression. METHODS Fifty endoscopic gastric biopsy specimens were studied for the presence of H pylori, degree and type of inflammation, and for HLA-DR antigen expression in the epithelium. The cases were chosen to represent different categories: inflamed gastric mucosa with (n = 13) and without (n = 20) H pylori, and non-inflamed mucosa (n = 17). RESULTS The antigen was aberrantly expressed in the antral mucosal epithelium in 11 of 12 cases (92%) with acute-on-chronic gastritis when H pylori was also present. It was present in the antrum in only seven of 18 H pylori negative cases (39%) with acute-on-chronic/chronic gastritis. One of three cases of acute gastritis and three of seven cases of chronic gastric erosions (non-inflamed category) showed positive staining. Generally, there was more staining in the antral than body mucosa and in the surface/foveolar epithelium than in the glands. No aberrant HLA-DR antigen expression was found in the 10 cases of normal gastric mucosa examined. CONCLUSIONS These findings suggest that H pylori may have a role in the induction of class II HLA antigen expression in chronic gastritis and lend support to the view that these organisms may be responsible for part of the inflammatory response.
