    Various stresses are considered to be involved in the development of gastric and duodenal ulcers. We interviewed patients of either gastric ulcer group (GU) or duodenal ulcer group (DU) with regular occupation who were admitted to our Psychosomatic Illness Department in order to examine the differences in the characteristics of their stress and developmental factors of their diseases between the two groups. Developmental factors were scored for comparison. The following results were obtained. Though group DU was generally younger than group GU, it tended to have a greater number of episodes. No significant difference was found between the two groups in living habits, life history, or familial, social and physical environments. However, group DU had greater stress than group GU in the working environment. A significantly greater number of patients in group DU smoked and had problems in personal relations as compared with GU. There was a significant correlation between smoking habit and stressfulness of the working environment in both groups. In group DU, there was a significant correlation between the father-child relationship and personal relations. In group DU, a significant number of those who had problems in the relation with their superiors at work had problems in the father-child relation. These findings show that patients with duodenal ulcer had more problems in the working environment, particularly in personal relations, than those with gastric ulcer, and smoking habit appears to accelerate the development of the diseases. Also, a possible association was suggested between problems of personal relations at work and the history of growth.

    Curcumin is known to possess anti‑inflammatory properties. Despite the fact that curcumin is known to be a strong inhibitor of H+, K+‑ATPase activity, the mechanism underlying the curcumin‑induced inhibition of the transcription of the H+, K+‑ATPase α subunit in gastric mucosal parietal cells remains unclear. The present study investigated the possible mechanism by which curcumin inhibits stomach H+, K+‑ATPase activity during the acute phase of gastric ulcer disease. A rat model of stress‑induced gastric ulcers was produced, in which the anti‑ulcer effects of curcumin were examined. Curcumin‑induced inhibition of the H+, K+‑ATPase promoter via histone acetylation, was verified using a chromatin immunoprecipitation assay. The results showed that curcumin improved stress‑induced gastric ulcer disease in rats, as demonstrated by increased pH values and reduced gastric mucosal hemorrhage and ulcer index. These effects were accompanied by a significant reduction in the level of histone H3 acetylation at the site of the H+, K+‑ATPase promoter and in the expression of the gastric H+,K+‑ATPase α subunit gene and protein. In conclusion, curcumin downregulated the acetylation of histone H3 at the site of the H+, K+‑ATPase promoter gene, thereby inhibiting the transcription and expression of the H+, K+‑ATPase gene. Curcumin was shown to have a preventive and therapeutic effect in gastric ulcer disease.

    The estimated volume of meal in the stomach 30 mins after sup(113m)In-DTPA administration was determined in patients with gastric ulcer and normal controls by 1) relating counts in the stomach to those in the whole field of view of the gamma camera and 2) aspirations. In the normal controls there was no significant difference between the two methods but in the gastric ulcer patients, the gamma camera method predicted significantly more meal in the stomach than was recovered by aspiration. It was suggested that the large low lying stomach found in gastric ulcer disease causes extensive overlap of the small bowel and invalidates measurements of gastric emptying made by a gamma camera.

    Full Text Available Background: Chronic inflammation and dys-regulation of the immune system mechanisms are now well established as primary triggers of gastric cancer and peptic ulcer disease. Galectin-9 (Gal-9 is a member of the galectin family and known as an inducer of cell aggregation, adhesion and apoptosis. Gal-9 interaction with its main ligand T-cell immunoglobulin and mucin domain protein-3 (Tim-3 leads to the apoptosis of T cells and dys-regulation of the immune responses in different tumors. In the current study, the mRNA expression pattern of Gal-9 was evaluated in gastric biopsies of patients with gastric cancer and peptic ulcer disease. Methods: In this case control study, gastric biopsies were obtained from 46 patients with gastric cancer, 44 patients with peptic ulcer disease and 41 cases with non-ulcer dyspepsia served as controls who underwent endoscopy for evaluation of their gastric problems. Infection with Helicobacter pylori was determined by rapid urease test for all participants and H&E staining for GC patients. Total RNA was extracted from all gastric tissues and used for cDNA synthesis. Relative expression of Gal-9 mRNA was determined by Real-Time PCR using β-actin as a housekeeping gene. Results: Gal-9 was similarly expressed in all three studied groups. No statistical difference was found for Gal-9 expression between gastric cancer patients and control group (2-ΔCt =0.022 vs 0.0144, p=0.30 and also between peptic ulcer and control groups (2-ΔCt =0.088 vs 0.144, p=0.16. No correlation was found for Gal-9 expression and infection with Helicobacter pylori (2-ΔCt = 0.1 vs 0.129, p=0.51. Conclusion: Similar expression of Gal-9 in gastric tissues from patients with gastric cancer, peptic ulcer and also non-ulcer dyspepsia individuals suggest no possible role of this molecule on tumorigenesis and immunoregulatory mechanisms of these gastric disorders.

    The inadequacy of information on the treatment of gastric candidiasis with antifungal agents promoted us to evaluate patients with fungal infections who had gastric ulcers and assess the need for proton-pump inhibitors or antifungal agents. Sixteen patients were included in the study. The criterion for the diagnosis of candidiasis was finding yeast and hyphae in the tissue or an ulcer on histological sections of biopsy samples. Surface fungi were not considered infections. In all cases with benign ulcers, follow-up endoscopy performed 6 weeks after proton-pump-inhibitor treatment revealed that the ulcer had improved without antifungal medication. However, in patients with malignant ulcers, surgical resection was necessary for a definitive cure. Two patients with lymphoma received combined chemotherapy and a proton-pump inhibitor, which improved their condition. The results of this study suggest that benign ulcers with candidiasis can be effectively treated by a proton-pump inhibitor without antifungal medication. However, surgical resection should be considered for malignant ulcers with candidiasis.

    LDH is found in many body fluids and tissues. Its level is elevated in many diseases. Thus the levels of LDH in serum and gastric juice were determined in both benign and malignant disease of the upper gastro-intestinal tract using the spectrophotometric techniques. 45 patients were included in the study (duodenal ulcer 19; gastric ulcer 6; gastric polyps 5; and gastric carcinoma 15). Serum LDH levels were not significantly elevated. However, the gastric juice LDH levels were significantly elevated in gastric polyps and gastric carcinoma. The mean levels were 96.81 +/- 14.31 and 443.2 +/- 58.1 i.u./L respectively. Serial estimation of gastric juice LDH in patients with gastric polyps showed a remarkable elevation at the time of malignant transformation.

    Background: T-cell immunoglobulin and mucin domain protein-3 (Tim-3), an inhibitory immunoregulatory receptor, has been recently implicated in tumor biology and tumor-associated immune suppression. In the present study, expression of Tim-3 was evaluated in gastric cancer (GC) and peptic ulcer disease (PUD) at both mRNA and protein levels. Methods: A total of 133 gastric tissue biopsies, comprising 43 from GC cases, 48 from PUD and 42 from non-ulcer dyspepsia (NUD) serving as controls were collected. Additionally, non-neoplastic adjacent tissue biopsies were also obtained from 6 patients with GC. Infection with Helicobacter pylori was determined by the rapid urease test for all participants and H&E staining was conducted for GC and PUD patients. Tim-3 relative mRNA expression was determined by SYBR Green based Real-Time PCR using β-actin as a reference gene. Tim-3 protein expression was also studied by immunohistochemistry in 7 GC, 7 PUD and 10 NUD tissue samples. Results: Tim-3 was expressed at higher levels in GC (p=0.030) and PUD (p=0.022) cases compared to he NUD group. Among paired samples obtained from gastric cancer patients, tumor tissues showed elevated Tim-3 expression (p=0.019) in comparison with adjacent non-neoplastic biopsies. Tim-3 mRNA findings were supported by detection of more Tim-3 protein in cancerous (p=0.002) and ulcerative (p=0.01) tissues than in controls. Tim-3 was similarly expressed in H. pylori positive and negative cases.Conclusion: Higher Tim-3 expression in patients with gastric cancer and peptic ulcer implies that it might be involved in immune regulation and establishment of these gastrointestinal diseases. Targeted immunotherapy by blocking of inhibitory receptors like Tim-3 could be a promising approach for gastric cancer treatment. Creative Commons Attribution License

    To investigate the possibility that an abnormality of gastric emptying exists in duodenal ulcer and to determine if such an abnormality persists after ulcer healing, scintigraphic gastric emptying measurements were undertaken in 16 duodenal ulcer patients before, during, and after therapy with cimetidine; in 12 patients with pernicious anemia, and in 12 control subjects. No difference was detected in the rate or pattern of gastric emptying in duodenal ulcer patients before and after ulcer healing with cimetidine compared with controls, but emptying of the solid component of the test meal was more rapid during treatment with the drug. Comparison of emptying patterns obtained in duodenal ulcer subjects during and after cimetidine treatment with those obtained in pernicious anemia patients and controls revealed a similar relationship that was characterized by a tendency for reduction in the normal differentiation between the emptying of solid and liquid from the stomach. The similarity in emptying patterns in these groups of subjects suggests that gastric emptying of solids may be influenced by changes in the volume of gastric secretion. The failure to detect an abnormality of gastric emptying in duodenal ulcer subjects before and after ulcer healing calls into question the widespread belief that abnormally rapid gastric emptying is a feature with pathogenetic significance in duodenal ulcer disease

    The CYP2C19 genotype has been found to be an important factor for peptic ulcer healing and H. pylori eradication, influencing the efficacy of proton pump inhibitors (PPIs) and the pathogenesis of gastric cancer. The aim of this study was to investigate clinical correlations of the CYP2C19 genotype in patients with gastritis, peptic ulcer disease (PUD), peptic ulcer bleeding (PUB) and gastric cancer in Thailand. Clinical information, endoscopic findings and H. pylori infection status of patients were assessed between May 2012 and November 2014 in Thammasat University Hospital, Thailand. Upper GI endoscopy was performed for all patients. Five milliliters of blood were collected for H. pylori serological diagnosis and CYP2C19 study. CYP2C19 genotypes were determined by polymerase chain reaction (PCR) and restriction fragment length polymorphism analysis (RFLP) and classified as rapid metabolizer (RM), intermediate metabolizer (IM) or poor metabolizer (PM). A total of 202 patients were enrolled including 114 with gastritis, 36 with PUD, 50 with PUB and 2 with gastric cancer. Prevalence of CYP2C19 genotype was 82/202 (40.6%) in RM, 99/202 (49%) in IM and 21/202 (10.4%) in PM. Overall H. pylori infection was 138/202 patients (68.3%). H. pylori infection was demonstrated in 72% in RM genotype, 69.7% in IM genotype and 47.6% in PM genotype. Both gastric cancer patients had the IM genotype. In PUB patients, the prevalence of genotype RM (56%) was highest followed by IM (32%) and PM(12%). Furthermore, the prevalence of genotype RM in PUB was significantly greater than gastritis patients (56% vs 36%: p=0.016; OR=2.3, 95%CI=1.1-4.7). CYP2C19 genotype IM was the most common genotype whereas genotype RM was the most common in PUB patients. All gastric cancer patients had genotype IM. The CYP2C19 genotype RM might be play role in development of PUD and PUB. Further study in different population is necessary to verify clinical usefulness of CYP2C19 genotyping in development of

    Forty-five patients with Helicobacter pylori (HP)-associated gastritis or ulcer disease were included in this study. Radionuclide-labelled solid meals were used to calculate gastric emptying times (GETs) and carbon-14 urea breath tests ([sup 14]C UBTs) were used to measure the HP colonies quantitatively. The patients were assessed according to the following two criteria: (a) the HP colony number (i.e. high or low) and (b) the recorded duration of the GET (i.e. long or short). There was no statistically significant difference in the incidence of abnormal GET between high and low [sup 14]C UBT patients or in the incidence of abnormal [sup 14]C UBT between long and short GET cases. In conclusion, no significant relationship between HP-associated gastritis or ulcer disease and GET was found in this study. (orig.)

    Helicobacter pylori (H. pylori) infection underlies gastric ulcer disease, gastric cancer and duodenal ulcer disease. The disease expression reflects the pattern and extent of gastritis/gastric atrophy (i.e., duodenal ulcer with non-atrophic and gastric ulcer and gastric cancer with atrophic gastritis). Gastric and duodenal ulcers and gastric cancer have been known for thousands of years. Ulcers are generally non-fatal and until the 20th century were difficult to diagnose. However, the presence and pattern of gastritis in past civilizations can be deduced based on the diseases present. It has been suggested that gastric ulcer and duodenal ulcer both arose or became more frequent in Europe in the 19th century. Here, we show that gastric cancer and gastric ulcer were present throughout the 17th to 19th centuries consistent with atrophic gastritis being the predominant pattern, as it proved to be when it could be examined directly in the late 19th century. The environment before the 20th century favored acquisition of H. pylori infection and atrophic gastritis (e.g., poor sanitation and standards of living, seasonal diets poor in fresh fruits and vegetables, especially in winter, vitamin deficiencies, and frequent febrile infections in childhood). The latter part of the 19th century saw improvements in standards of living, sanitation, and diets with a corresponding decrease in rate of development of atrophic gastritis allowing duodenal ulcers to become more prominent. In the early 20th century physician's believed they could diagnose ulcers clinically and that the diagnosis required hospitalization for "surgical disease" or for "Sippy" diets. We show that while H. pylori remained common and virulent in Europe and the United States, environmental changes resulted in changes of the pattern of gastritis producing a change in the manifestations of H. pylori infections and subsequently to a rapid decline in transmission and a rapid decline in all H. pylori-related diseases.

    Full Text Available The common acid related diseases of the upper gastrointestinal tract could be considered as primarily due to the defect in barrier function either of the gastric mucosal or duodenal epithelium leading to the formation of gastric or duodenal ulcers. An attempt was made in this review to discuss the classification, pathophysiology, diagnosis and treatment of gastric ulcer in dogs. Early surgical advances in the management of peptic ulcers are emphasized that were then subsequently replaced by pharmacological treatment (histamine H2-receptor antagonists, proton pump inhibitors and considered as the major strategy against the acid disorders.

    Full Text Available BACKGROUND It is fundamental that any gastric ulcer should be regarded as being malignant, no matter how classic the features of a benign gastric ulcer. Multiple well-targeted biopsies, as many as 10, should always be taken before an ulcer can be definitely accepted as benign, which can be detected by a simple outpatient procedure of upper gastrointestinal endoscopy. MATERIALS AND METHODS Cases undergoing upper GI endoscopy in the Department of General Surgery, M.K.C.G. Medical College Hospital, from June 2015 - July 2017 were included in the study to determine the malignancy developing in cases of gastric ulcer keeping in mind the above-mentioned facts. RESULTS Out of 1782 cases of total upper GI endoscopy performed, 197 cases were detected as gastric ulcer. The incidence of malignancy in a gastric ulcer in this study was 3.04%. Peptic ulcer disease was more common in male sex compared to females. Incidence of malignancy in gastric ulcer was higher in smokers and alcoholics. The patients with H. pylori were more prone to gastric ulceration and its subsequent malignant transformation are well established. CONCLUSION Gastric ulcer maybe a precursor lesion of gastric malignancy. Multiple well-targeted biopsy from ulcer at endoscopy may lead to detection of early gastric cancer.

    Helicobacter pylori infection is associated with peptic ulcer disease and gastric cancer. The aim of this work was to describe, to compare H. pylori antigenic profiles, and to characterize the antibody response against Colombian strains in gastric cancer and peptic ulcer patients. Liquid culture supernatants were used to determine the antigenic profiles of 35 H. pylori strains by immunoblotting using a pool of positive sera. Characterization of strains included the evaluation of cytotoxic and vacuolating activities. The serologic antibody profiles of 124 patients (54 duodenal ulcer and 70 gastric cancer) were analyzed against two native strains (Hpu24, Hpc29) and NCTC11638. Antibodies to specific antigenic bands in each strain were related with presentation. Differences among antigenic profiles were observed between native isolates with each serum recognizing a wide range of antigens (30-120 Kd). A 68 Kd band in Hpu24 strain was recognized by 50% of sera from peptic ulcer patients but not by gastric cancer sera (p =.000). The immune profiles differed according to the strain used (i.e. a given sera did not recognize the same bands in different strains). Detection of H. pylori in gastric mucosa was associated with the presence of antibodies against low molecular weight antigenic bands. The heterogeneity in the antibody response to H. pylori and the prevalence specific anti-H. pylori antibodies in a specific disease depend on the strain used as antigen. The results support the hypothesis that there may be a differential antibody response to carcinogenic and ulcerogenic strains and suggest that there are antigenic bands that could be useful as markers of disease.

    The bacterial pathogen Helicobacter pylori is the etiological agent of a range of gastrointestinal pathologies including peptic ulcer disease and the major killer, gastric adenocarcinoma. Infection with this bacterium induces a chronic inflammatory response in the gastric mucosa (gastritis). It is this gastritis that, over decades, eventually drives the development of H. pylori-associated disease in some individuals. The majority of studies investigating H. pylori pathogenesis have focused on factors that promote disease development in infected individuals. However, an estimated 85% of those infected with H. pylori remain completely asymptomatic, despite the presence of pathogenic bacteria that drive a chronic gastritis that lasts many decades. This indicates the presence of highly effective regulatory processes in the host that, in most cases, keeps a check on inflammation and protect against disease. In this minireview we discuss such known host factors and how they prevent the development of H. pylori-associated pathologies. Copyright © 2016 the American Physiological Society.

    Gastric outlet obstruction (GOO) is a rare complication of peptic ulcer disease (PUD). The endoscopic balloon dilatation (EBD) associated with medical treatment of Helicobacter pylori is a successful method in the management of pyloric stenosis. The aim of this study was to describe epidemiological, clinical, and endoscopic characteristics of GOO related to PUD and to evaluate the effectiveness, safety, and outcome of EBD. In a retrospective study of patients seen between 1999 and 2009 with symptoms of GOO secondary to PUD, pyloro-bulbar stenosis was confirmed by endoscopic examination. Balloon dilatation was performed when obstruction persisted after treatment with double-dose proton-pump inhibitor (PPI) intravenously for 7-10days. The H. pylori status was assessed with histology, and eradication therapy was prescribed for infection. A total of 45 consecutive patients (38 males, 7 females median age, 51.9years; range, 20-58years) with symptoms of GOO secondary to PUD underwent EBD. Median follow-up time of the 45 patients was 32months (range, 4-126months). The immediate success rate of the procedure was 95.5%. Clinical remission was noted in 84.4% of the patients. Remission without relapse was observed in 55.8%, 30months after the dilatation. Pyloric stenosis relapsed in 15 patients (39.5%) after a median period of 22.9months. The dilatation was complicated in three patients (6.7%, two perforations and one bleeding). A total of 13 patients (29%) underwent surgery. H. pylori was found to be positive in 97.7% of the patients, and was eradicated in 78.4% of them. Smoking and failure of H. pylori eradication were associated with the relapse of the stenosis. EBD is a simple, effective, and safe therapy for the GOO related to PUD, producing short- and long-term remission. Copyright © 2015 Arab Journal of Gastroenterology. Published by Elsevier B.V.

    Equine gastric ulcer syndrome is one of the most frequently reported diseases in thoroughbred racehorses. Although several risk factors for the development of gastric ulcers have been widely studied, investigation of microbiological factors has been limited. In this study, the presence of Helicobacter spp. and the gastric microbial communities of thoroughbred racehorses having mild to severe gastric ulcers were investigated. Although Helicobacter spp. were not detected using culture and PCR techniques from 52 gastric biopsies and 52 fecal samples, the genomic sequences of H. pylori and H. ganmani were detected using nextgeneration sequencing techniques from 2 out of 10 representative gastric samples. The gastric microbiota of horses was mainly composed of Firmicutes (50.0%), Proteobacteria (18.7%), Bacteroidetes (14.4%), and Actinobacteria (9.7%), but the proportion of each phylum varied among samples. There was no major difference in microbial composition among samples having mild to severe gastric ulcers. Using phylogenetic analysis, three distinct clusters were observed, and one cluster differed from the other two clusters in the frequency of feeding, amount of water consumption, and type of bedding. To the best of our knowledge, this is the first study to investigate the gastric microbiota of thoroughbred racehorses having gastric ulcer and to evaluate the microbial diversity in relation to the severity of gastric ulcer and management factors. This study is important for further exploration of the gastric microbiota in racehorses and is ultimately applicable to improving animal and human health.

    A case of CT demonstration of a bleeding gastric ulcer is presented, in a patient with confusing clinical manifestations. Abdominal CT was performed without oral contrast medium administration, and showed extravasation of intravenous contrast into a gastric lumen distended with material of mixed attenuation. It is postulated that if radiopaque oral contrast had been given, peptic ulcer bleeding would probably have been masked. CT demonstration of gastric ulcer bleeding, may be of value in cases of differential diagnostic dilemmas

    Gastritis and gastric ulcers are an important cause of morbidity and mortality in canine athletes. Although the majority of scientific work on this condition has been performed in ultraendurance racing sled dogs, this condition has been identified in other canine athletes, including sled dogs competing in shorter events and dogs performing off-leash explosive detection duties. The cause of the syndrome is unknown, but current hypotheses propose a link between exercise-induced hyperthermia and loss of gastric mucosal barrier function as an early event in the pathogenesis. Treatment is focused on prevention of clinical disease using acid secretion inhibitors, such as omeprazole, which has excellent efficacy in controlled clinical studies.

    Patients with gastric ulcers have significantly higher risk of gastric cancer, especially within 2 years after diagnosis. We used data from a national database to develop a personalized risk prediction model for patients with peptic ulcer diseases. We collected data from Taiwan's National Health Insurance Research Database on 278,898 patients admitted for the first time with a primary diagnosis of peptic ulcer disease. We used the data to develop a nomogram, which we validated by discrimination and calibration, and in a test cohort. Cumulative incidences of study subjects predicted by the nomogram were examined. In total, 1269 subjects developed gastric cancer. Age, sex, peptic ulcer sites, peptic ulcer complications, Helicobacter pylori eradication, nonsteroidal anti-inflammatory drug use, and surveillance endoscopy were independent factors associated with risk of gastric cancer (all P peptic ulcer disease. The nomogram provides a prognostic tool that can be easily used for individuals and can help physicians explain risk levels to patients. Copyright © 2015 AGA Institute. Published by Elsevier Inc.

    Helicobacter pylori can colonize the gastric mucosa and is considered as a risk factor for chronic active gastritis, peptic ulcer, gastric adenocarcinoma and primary gastric lymphoma. Among its various virulence factors, vacuolating cytotoxin encoded by vacA and cytotoxin-associated toxin encoded by cagA gene play an important role. The aims of this study were the detection of H.pylori vacA s and m genotypes, investigation of the association between vacA genotypes and cagA gene presence, and evaluation of the correlation between those factors and the clinical diagnosis. Gastric tissue specimens of patients who were clinically diagnosed as peptic ulcer disease (PUD) and non-ulcer dyspepsia (NUD) were included in the study. A total of 29 patients (age range: 18-74 years, mean age: 47.8 ± 13.6 years; 19 were female) without any familial relationship were evaluated. Thirteen (44.8%) of the patients were diagnosed clinically as PUD, while 16 (55.2%) as NUD. All of the patients' gastric tissue samples obtained by endoscopy were urease positive. H.pylori DNA was extracted from the tissue specimens by proteinase-K, phenol-chloroform-isoamyl alcohol method and vacA s, m1, m2 and cagA regions were identified by polymerase chain reaction (PCR) using four different primer sets. In addition, DNA sequencing was performed for the protected 785 base-pairs region of vacA m gene in all of the samples, and the sequences were aligned with Gene-Bank sequences, creating a phylogenetic tree. The distribution of vacA genotypes between 29 H.pylori positive patients were found as; s1m1 (n= 16), s1m2 (n= 6) and s2m2 (n= 7), while 19 patients yielded positive results for cagA gene. CagA positivity was detected in all of the 16 patients harboring s1m1 genotype, and 13 of those were the patients diagnosed as PUD (p= 0.008). Genotyping data achieved by phylogenetic analysis of the vacA m region were compatible with m genotypes identified by PCR. In conclusion, we detected a significant

    Full Text Available Introduction & Objective: Different studies show that the reasons for clinically diverse outcomes of infections caused by H. pylori may include host and environmental factors as well as differences in the prevalence or expression of bacterial virulence factors. The aim of this study was to study the distribution of different genotypes of major virulence factors cagA, vacA and ureAB among H. pylori strains isolated from patients with gastric ulcer (ulcerative disease and patients with gastritis (non ulcerative disease.Materials & Methods: In this cross sectional study 65 H. pylori strains, 30 from patients with gastric ulcer and 35 from patients with non ulcerative gastritis disease were investigated by RFLP-PCR.Results: The prevalence of vacA-positive strains in ulcerative patients was significantly more than that in non ulcerative patients (P0.05.Conclusion: It seems that in the patients under our study the presence of cagA gene may not necessarily be a risk factor for ulcer disease, while a homologous genotype of vacA appears to be associated with an increase risk of ulcer development. Lastly, despite the existence of a high degree of genomic variability within ureAB, conserved DNA banding profiles are distributed in our areas.

    AIM: To compare the prevalence of Helicobacter pylori (H pylori) IgG and IgA antibodies between adult subjects, with defined gastric diseases, nondefined gastric disorders and those representing the population. METHODS: Data on H pylori IgG and IgA antibodies, determined by enzyme immunoassay, were analyzed in 3 252 subjects with DGD including 482 patients with gastric ulcer, 882 patients with duodenal ulcer, 1 525 patients with chronic gastritis only and 363 subjects with subsequent gastric cancer, 19 145 patients with NoDg and 4 854 POPUL subjects. The age-adjusted prevalences were calculated for 1- and 20-year age cohorts. RESULTS: The prevalences of IgG antibodies were equally high (89-96%) in all 20-year age cohorts of the DGD groups, whereas the prevalences of IgG antibodies were lower and increased by age in the POPUL and NoDg groups. The prevalences of IgA antibodies were also higher in the DGD groups; among them CA (84-89%) and GU groups (78-91%) showed significantly higher prevalences than DU (68-77%) and CG patients (59-74%) (OR 2.49, 95%CI 1.86-3.34 between the GU and DU groups). In the CA, GU, and DU groups, the IgA prevalences showed only minor variation according to age, while they increased by age in the CG, POPUL, and NoDg groups (P≤0.0001). The IgA response, but not the IgG response, was associated with an increased risk of CA (OR 2.41, 95%CI 1.79-3.53) and GU (OR 2.57, 95%CI 1.95-3.39) in comparison with CG patients. CONCLUSION: An IgA antibody response during H pylori infection is significantly more common in CA and GU patients as compared with CG patients. PMID:16425400

    It is well known that gastric ulcers are most often found at anglus and upper corpus in the elderly. The number of gastric ulcer found at upper corpus hold half of all cases in the elderly patients with bleeding ulcer. Sixty percent of the elderly patients with bleeding ulcer took NSAIDs including low-dose aspirin in authors' hospital. Now it is easy to treat and cure bleeding ulcers due to development of endoscopic hemostasis and antiulcer drugs such as proton pump inhibitor(PPI). However, the elderly patients sometimes result in fatal outcome on bleeding from gastric ulcer. Therefore, it is important to prevent ulcer complications by PPI for the high-risk group such as elderly patients taking NSAIDs.

    Gastric ulcer is one of the most common chronic gastrointestinal diseases characterized by a significant defect in the mucosal barrier. Helicobacter pylori (H. pylori) infection and the frequent long-term use of non-steroidal anti-inflammatory drugs are major factors involved in gastric ulcer development. Acid inhibitors and antibiotics are commonly used to treat gastric ulcer. However, in the last few decades, the accumulating evidence for resistance to antibiotics and the side effects of antibiotics and acid inhibitors have drawn attention to the possible use of probiotics in the prevention and treatment of gastric ulcer. Probiotics are live microorganisms that when administered in adequate amounts confer health benefits on the host. Currently, the available experimental and clinical studies indicate that probiotics are promising for future applications in the management of gastric ulcers. This review aims to provide an overview of the general health benefits of probiotics on various systemic and gastrointestinal disorders with a special focus on gastric ulcer and the involved cellular and molecular mechanisms: i) Protection of gastric mucosal barrier; ii) upregulation of prostaglandins, mucus, growth factors and anti-inflammatory cytokines; iii) increased cell proliferation to apoptosis ratio; and iv) induction of angiogenesis. Finally, some of the available data on the possible use of probiotics in H. pylori eradication are discussed. PMID:27347010

    Equine gastric ulcer syndrome (EGUS) is an umbrella term used to describe ulcers in the nonglandular squamous and glandular mucosa, terminal esophagus, and proximal duodenum. Gastric ulcers in the squamous and glandular regions occur more often than esophageal or duodenal ulcers and likely have a different pathogenesis. At present, omeprazole is accepted globally as the best pharmacologic therapy for both regions of the stomach; however, the addition of coating agents and synthetic prostaglandins could add to its effectiveness in treatment of EGUS. Dietary and environmental management are necessary for prevention of recurrence. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available GIST tumors is very unusual in the young and middle aged and a high index of suspicion is needed for the diagnosis in young patients who present with upper gastrointestinal bleeding. Appropriate imaging such as a Computed tomographic scan (CT scan may identify this tumor which may easily be misdiagnosed as a bleeding Peptic Ulcer Disease in the young. We present a case of a healthy 38 year old man with no alcohol use who presented with epigastric pain and melena and subsequent torrential bleeding uncontrolled during endoscopy necessitating an emergency exploratory laparotomy by the general surgery team. The bleeding intraluminal component of the tumor with gross splenic and pancreatic involvement was identified and surgical management consisted of a wedge resection of the greater curvature of the stomach incorporating the tumor and the spleen with successful dissection of the tumor off the tail of the pancreas. Histology was positive for C-KIT and DOG-1 markers. Postoperative course was uneventful and he is presently on Imatinib Mesylate.

    To compare on the basis of helical CT findings gastric wall thickening of peptic gastric ulcer with that of gastric adenocarcinoma with ulcer. Thirty-eight patients with pathologically proven gastric lesion (17 cases of peptic ulcer and 21 cases of ulcerative or ulceroinfiltrative gastric cancer (Borrman type II, III) underwent helical CT, and the findings were retrospectively reviewed in terms of maximum abnormal wall thickness, preservation of the inner enhancing layer, the presence three discriminate layers of gastric wall, and enhancement pattern. The enhancement pattern of abnormally thick wall was compared with that of the portal phase of back muscle, and was defined as low, iso, or high. The Chi-square test and Student t test were used for statistical analysis. In cases of peptic ulcer and gastric cancer with ulceration, maximum abnormal wall thickness was 7-30 (mean, 16.1)mm, and 11-33 (mean, 21.8)mm, respectively. The inner enhancing layer was preserved in 15 of 17 patients (88.2%) and one of 21 (4.8%); three discriminate layers of gastric wall were observed in 8 of 17 patients (47.0%), and one of 21 (4.8%). The enhancement pattern was low in 12 of 17 patients (70.5%), and 3 of 21 (14.3%); iso in 4 of 17 (23.5%), and 4 of 21 (19.0%), and high in one of 17 (5.9%), and 14 of 21 (66.7%). All figures refer, respectively, to the two distinct conditions. In terms of preservation of the inner enhancing layer, three discriminate layers of gastric wall, and a low enhancement pattern, there were statistically significant differences between peptic ulcer and gastric adenocarcinoma with ulcer. Where the enhancement was high, however, the statistically significant difference between the two conditions was even greater. There was no statistically significant difference in terms of gastric wall thickness or iso-attenuation of thickened gastric.

    Full Text Available Context and Objectives Focally enhanced gastritis and macrophage microaggregates are found in the upper gastrointestinal involvement of Crohn’s disease, and may reflect an underlying defective innate immunity. These features, however, are also described in patients with Helicobacter pylori infection. The role of these gastric abnormalities in the diagnosis of Crohn’s disease was assessed in a population with high prevalence of H. pylori infection. Methods Thirty-seven Crohn’s disease, 26 ulcerative colitis, and 30 control patients were included. The H. pylori status was evaluated by the rapid urease test and histology. The presence of focally enhanced gastritis and macrophage microaggregates was recorded. Results Focally enhanced gastritis was present in 24% of Crohn’s disease patients, 4% of ulcerative colitis patients and 11.5% of controls, presenting an overall sensitivity and specificity for Crohn’s disease of 24% and 88%, respectively. Macrophage microaggregates were found in all groups, but were only detected in ulcerative colitis and controls in association with H. pylori infection, with an overall sensitivity and specificity for Crohn’s disease of 61% and 69%, respectively. In the absence of H. pylori infection, focally enhanced gastritis and macrophage microaggregates were significantly associated with Crohn’s disease (P<0.02 and P = 0.001 respectively. Conclusions Focally gastritis and macrophage microaggregates are suggestive of Crohn’s disease only in H. pylori-negative specimens. HEADINGS - Crohn’s disease. Ulcerative colitis. Gastritis.

    1997-12-01

    Recurrent ulceration following gastrectomy for peptic ulcer disease typically occurs within the first several years postoperatively. Since 1990, we have managed 20 patients who had undergone previous gastrectomy for peptic ulcer and developed ulcer recurrence more than 10 years postoperatively. Mean age at recurrence was 64 years, and the average time from original surgery to recurrent ulceration was 21 years (range, 10-36 years). All patients had undergone vagotomy and antrectomy (17 patients) or subtotal gastrectomy (3 patients). Presenting symptoms included gastric outlet obstruction (70%) and bezoar formation (60%). Endoscopic findings in this group of patients included a stenotic gastric outlet (70%) and marginal ulcerations (80%). Thirteen of 15 patients tested (87%) were Helicobacter pylori positive. Reoperation included partial resection of the gastric pouch and exploration for persistent vagus nerve. Twelve patients underwent Roux-en-Y reconstruction, whereas eight patients had Bilroth II reconstruction. Three of the latter group also had Braun enteroenterostomy performed. Good to excellent clinical results were obtained in 80 per cent of patients. The four patients with poor outcomes shared the following characteristics: 1) H. pylori-positive status, 2) presence of a preoperative bezoar, 3) Roux-en-Y reconstruction. Our current approach is to avoid Roux-en-Y construction in favor of Braun enteroenterostomy. Further prospective analysis of long-term postgastrectomy patients is needed to determine whether this clinical picture represents a new postgastrectomy syndrome.

    When compared with a matched population group, 4466 ulcer patients who had had gastric surgery between 1940 and 1960 showed no difference in the risk of death from gastric cancer in the first 20 years of follow-up but a 4.5-fold increase thereafter. In duodenal ulcer patients there was an initial decrease in risk followed by a 3.7-fold increase after 20 or more years. Since the initial decrease was seen only in the gastrectomy patients and not in those who had truncal vagotomy and drainage, it may have been due to the reduction in mucosal surface. The increased risk 20 years after duodenal ulcer surgery was greater in vagotomy patients than in gastrectomy patients. In gastric ulcer patients a 3.0-fold increase in risk for the first 20 years rose to a 5.5-fold increase thereafter. After 20 years, patients treated with the Bilroth II operation were at higher risk than those treated with Bilroth I, consistent with a role for bile reflux in gastric carcinogenesis. The finding that the risk differs according to original pathology and type of operation may explain the discrepancies between previous studies.

    Lactase deficiency (LD) has been described in associated with peptic ulcer disease of the upper gastrointestinal tract, but little has been known as to the incidence of LD in the patients with ulcer disease of the upper GI tract or with gastric carcinoma. The purpose of the present study is to investigate the incidence of LD in gastric and/or duodenal ulcer disease and in gastric carcinoma, and to hypothesize the possible effect of these diseases on LD. Clinical materials consisted of 40 cases of active duodenal ulcer disease, 19 cases of benign gastric ulcer, 5 cases of multiple ulcers both in the stomach and duodenum, and 32 cases of gastric carcinoma. We used the lactose-barium test in diagnosing LD. X-ray findings were assessed according to the criteria described by Laws et al. and Preger and Amberg in the small-bowel film obtained at 30 minutes after the ingestion of some 200 ml of lactose-barium meal which contained 50 gm of lactose. Our clinical study revealed that the incidence of LD in duodenal ulcer was 50%, in gastric ulcer 57.9%, in gastric and duodenal ulcer 60%, and in gastric carcinoma 46.9%. The difference of incidence between each disease were statistically not significant, but the difference between the disease group and normal control was highly significant. The incidence of LD in disease group was nearly twice as high as that of normal control (27.7%). It is speculated that high incidence of LD in peptic ulcer disease of upper GI tract in particular may be associated with high acidity, the analog of which is found in Zollinger-Ellison syndrome. But high acidity is not a prominent feature in gastric carcinoma which is attended by almost equally high incidence of LD. It is therefore likely that the intolerability to lactose is caused by much complicated mechanism of versatile factors

    A wide range of incidence of diodeno-gastric bile reflux has been reported in patients with duodenal ulcer (DU) or gastric ulcer (GU). Using either 100 units of CCK i/v or a fatty meal of 320 Cal containing 20 g fat to contract the gall bladder, we have investigated the incidence of reflux in 170 subjects: CCK (Control: 20; DU: 60; GU: 19), Meal (Control: 19; DU: 37; GU: 15). The CCK or meal was given in the supine subject 30 minutes after injection of 75 MBq sup(99m)Tc diethyl Hida. Reflux was considered present if labelled bile was seen in the stomach on 3 successive 2 minute gamma camera pictures. The percentage of patients showing reflux was as follows: CCK (Control: 45%; DU: 53%; GU: 58%), Meal (Control: 11%; DU: 24%; GU: 40%). These results have been compared using the Chi-squared test. There was no significant difference in the incidence of reflux between control, DU or GU patients either in the group of patients given CCK or a meal. However, reflux was more common after CCK than the meal in control subjects (p<0.05) and in those with DU (p<0.01) but not in those with GU.

    Full Text Available A benign antral gastric ulcer in an adult causing gastric outlet obstruction was demonstrated by ultrasonography. The extent and benign nature of the ulcer was suggested by ultrasound before gastric surgery was performed. Features implying a benign gastric ulcer were: observation of peristaltic waves through the underlying muscular layer, homogenicity of the ulcer crater and characteristic mound or volcano-like appearance of the heaped-up folds of mucosa. The differential diagnosis and the role of ultrasound in the diagnosis of gastric ulcers are discussed.

    Full Text Available Background & Aims: The peptic ulcer heals through a complex process, although the ulcer relapse often occurs several years later after healing. Our hypothesis is that even after visual evidence of healing of gastric ulceration, the regenerated epithelium is aberrant for an extended interval, increasing susceptibility of the regenerated epithelium to damage and further diseases. Methods: Gastric ulcers were induced in mice by serosal topical application of acetic acid. Results: Gastric ulcers induced by acetic acid visually healed within 30 days. However, regenerated epithelial architecture was poor. The gene profile of regenerated tissue was abnormal, indicating increased stem/progenitor cells, deficient differentiated gastric cell types, and deranged cell homeostasis. Despite up-regulation of PDX1 in the regenerated epithelium, no mature antral cell type was observed. Four months after healing, the regenerated epithelium lacks parietal cells, trefoil factor 2 (TFF2 and (sex-determining region Y-box 9 (SOX9 remain up-regulated deep in the gastric gland, and the Na/H exchanger 2 (a TFF2 effector in gastric healing remains down-regulated. Gastric ulcer healing was strongly delayed in TFF2 knockout mice, and re-epithelialization was accompanied with mucous metaplasia. After Helicobacter pylori inoculum 30 days after ulceration, we observed that the gastric ulcer selectively relapses at the same site where it originally was induced. Follow-up evaluation at 8 months showed that the relapsed ulcer was not healed in H pylori–infected tissues. Conclusions: These findings show that this macroscopically regenerated epithelium has prolonged abnormal cell distribution and is differentially susceptible to subsequent damage by H pylori.

    Full Text Available Gastrointestinal tract amyloidosis has been reported in rare instances and related symptoms are usually nonspecific to the disease process. We present a patient who initially had melena on anticoagulation and endoscopy revealed a bleeding gastric ulcer. Hemostasis was achieved. The patient had a recurrence of symptoms despite being off anticoagulation months later and at that time repeat endoscopy showed multiple gastric ulcers with surrounding friable mucosa. Biopsy results were significant for light chain associated-amyloidosis. This case represents a rare cause of gastric ulcer.

    Studies assessing the effect and mechanism of probiotics on diseases of the upper gastrointestinal tract (GI) including gastric ulcers are limited despite extensive work and promising results of this therapeutic option for other GI diseases. In this study, we investigated the mechanisms by which the probiotic mixture VSL#3 (a mixture of eight probiotic bacteria including Lactobacilli, Bifidobacteria and Streptococcus species) heals acetic acid induced gastric ulcer in rats. VSL#3 was administered orally at low (6×109 bacteria) or high (1.2×1010 bacteria) dosages from day 3 after ulcer induction for 14 consecutive days. VSL#3 treatments significantly enhanced gastric ulcer healing in a dose-dependent manner. To assess the mechanism(s) whereby VSL#3 exerted its protective effects, we quantified the gene expression of several pro-inflammatory cytokines, protein and expression of stomach mucin-Muc5ac, regulatory cytokine-IL-10, COX-2 and various growth factors. Of all the components examined, only expression and protein production of VEGF was increased 332-fold on day 7 in the ulcerated tissues of animals treated with VSL#3. Predictably, animals treated with VEGF neutralizing antibody significantly delayed gastric ulcer healing in VSL#3 treated animals. This is the first report to demonstrate high efficacy of the probiotic mixture VSL#3 in enhancing gastric ulcer healing. Probiotic efficacy was effective at higher concentrations of VSL#3 by specifically increasing the expression and production of angiogenesis promoting growth factors, primarily VEGF. PMID:23484048

    Helicobacter pylori is the major pathogenesis of peptic ulcer disease. It is important for the endoscopists to detect H. pylori infection during endoscopy. Only one endoscopic diagnostic method can be used due to the limitation of health insurance payments in Taiwan. Most endoscopists use the tissue obtained from the ulcer margins for histopathological examination and detection of H. pylori infection in patients with gastric ulcer. Whether this is suitable deserves study. A total of 103 consecutive subjects with gastric ulcer were recruited. Biopsy specimens from the margins of gastric ulcer were sent for histological examination with modified Giemsa stain. Two biopsy specimens from the antrum and greater curvature site of mid body were embedded in rapid urease test (CLOtest). A patient was classified as H. pylori positive if either CLOtest or histology were positive. 57 patients had H. pylori infection. The detection rate of rapid urease test and histological examination was 96.5% (55/57) and 59.6% (35/57), respectively. Of the 3 patients who had positive histological examinations and negative urease test, only one was confirmed again to have H. pylori infection. The detection rates of rapid urease test and histological examination in different locations of ulcer (antrum/angularis/proximal stomach) were 92.6%/100%/100% and 81.5%/42.1%/36.4%, respectively. Our study shows that rapid urease test has higher detection rate than histological examination of the biopsy specimens obtained from the margins of gastric ulcer in diagnosis of H. pylori infection. Under the consideration of the health insurance payments limitation and elimination of false-negative detection rate of H. pylori infection, we strongly recommend the rapid urease test from the antrum and body specimens rather than from the ulcer margins for detection of the bacteria in patients with gastric ulcer disease.

    The pathogenesis of the higher occurrence of peptic ulcer disease in cirrhotic patients is complex. Platelets can stimulate angiogenesis and promote gastric ulcer healing. We compared the expressions of proangiogenic growth factors and their receptors in the gastric ulcer margin between cirrhotic patients with thrombocytopenia and those of non-cirrhotic patients to elucidate possible mechanisms. Eligible cirrhotic patients (n = 55) and non-cirrhotic patients (n = 55) who had gastric ulcers were enrolled. Mucosa from the gastric ulcer margin and non-ulcer areas were sampled and the mRNA expressions of the proangiogenic growth factors (vascular endothelial growth factor [VEGF], platelet derived growth factor [PDGF], basic fibroblast growth factor [bFGF]) and their receptors (VEGFR1, VEGFR2, PDGFRA, PDGFRB, FGFR1, FGFR2) were measured and compared. Platelet count and the expressions of these growth factors and their receptors were correlated with each other. The two groups were comparable in terms of gender, ulcer size and infection rate of Helicobacter pylori. However, the cirrhotic group were younger in age, had a lower platelet count than those in the non-cirrhotic group (pexpressions of PDGFB, VEGFR2, FGFR1, and FGFR2 in gastric ulcer margin when compared with those of the non-cirrhotic patients (pexpressions of PDGFB and VEGFR2, FGFR1, and FGFR2 were well correlated with the degree of thrombocytopenia in these cirrhotic patients (ρ>0.5, pimplied that diminished activity of proangiogenic factors and their receptors may contribute to the pathogenesis of gastric ulcers in cirrhotic patients.

    Garlic, in its natural plant state, has a great history in ancient medicine as a remedy for many diseases. In our study, the gastroprotective effect of aged garlic extract (AGE) and the possible underlying mechanisms were investigated in an experimental model of indomethacin-induced gastric ulcer. Male Wistar rats were divided into four groups: (normal control, n = 20), ulcer control (indomethacin group, n = 20), (omeprazole group, n = 30) and (garlic group, n = 20). Each dose of garlic and omeprazole was given to rats orally daily for 10 consecutive days before induction of ulcer by indomethacin. Indomethacin was given as a single oral dose (100 mg/kg). Four hours later after indomethacin treatment, the rats were sacrificed and gastric tissue was obtained for histopathological examination, calculation of ulcer index and measurement of oxidative stress markers as well as gastroprotective mediators. The results showed that indomethacin induced gastric ulcer (ulcer index = 2900), was associated with a significant increase of tumor necrosis factor-alpha and malondialdehyde, and significant decrease of the gastroprotective mediators prostaglandin E2, glutathione (GSH) and nitric oxide (NO) compared with normal control. Pretreatment with AGE produced comparable results with those obtained in the omeprazole group; the preventive index in the AGE group was 83.4% compared with 94.5% in the omeprazole group. The prophylactic role of AGE in indomethacin-induced ulcer was, in part, mediated by decreasing oxidative stress and increasing gastric level of PGE2, GSH, and NO. AGE corrected the histopathological abnormalities in gastric tissue and proved a promising gastroprotective role in gastric ulcer. Copyright © 2016 Elsevier Inc. All rights reserved.

    Cytomegalovirus infection is an important cause of morbidity in immunosupressed patients with Human Immunodeficiency Virus (HIV). In this paper we present a 43 years old man with renal failure under hemodialysis, several blood transfusions because of anemia and three months of disease characterized by epigastric pain, specially at nights, ameliorated with antacid drugs. Other symptoms were early satisfy, vomits and weigh loss (18Kg). At clinical exam, the patient was pallid, presented adenopathies at cervical and inguinal regions and had a pain at epigastric region in profound touch palpation. The most important exams were HB: 10mg/dl, CMV: 83.5, leukocytes 7000, lymphocytes: 1715, erythrocyte sedimentation rate 49mm/h, the venon test (-), and Giardia lamblia trophozoites in stools. The studies demonstrated the patient was seropositive for HIV and the tests for IgG CMV and IgG Herpes virus resulted seropositives too. At endoscopy the esophagus mucosa was covered by a white plaque which suggests candida infection. In the stomach, over the body gastric, we found a big and deep ulcerated lesion (45 x 41mm), with defined rims and white fund. Biopsy from the edges of the gastric ulcer had the characteristic CMV intranuclear and intracytoplasmic inclusions; we confirmed the diagnosis by immunohystochemistry. The patient receives ganciclovir an then HAART and is getting well.

    Full Text Available Gastric ulcers are among the most common diseases affecting humans. This study aimed at investigating the gastroprotective effects of manuka honey against ethanol-induced gastric ulcers in rats. The mechanism by which honey exerts its antiulcer potential was elucidated. Four groups of rats were used: control, ethanol (ulcer, omeprazole, and manuka honey. Stomachs were examined macroscopically for hemorrhagic lesions in the glandular mucosa, histopathological changes, and glycoprotein detection. The effects of oxidative stress were investigated using the following indicators: gastric mucosal nitric oxide (NO, reduced glutathione (GSH, lipid peroxide (MDA, measured as malondialdehyde glutathione peroxidase (GPx, superoxide dismutase (SOD, and catalase. Plasma tumour necrosis factor-α, interleukin-1β, and IL-6 were also measured. Manuka honey significantly decreased the ulcer index, completely protected the mucosa from lesions, and preserved gastric mucosal glycoprotein. It significantly increased gastric mucosal levels of NO, GSH, GPx, and SOD. Manuka honey also decreased gastric mucosal MDA and plasma TNF-α, IL-1β, and IL-6 concentrations. In conclusion, manuka honey likely exerted its antiulcer, effect by keeping enzymatic (GPx and SOD and nonenzymatic (GSH and NO antioxidants as well as inflammatory cytokines (TNF-α, IL-1β, and IL-6 in a reduced form, inhibited lipid peroxidation (MDA, and preserved mucous glycoproteins levels.

    Abstract Although endoscopic ultrasonography (EUS) is the first-choice imaging modality for predicting the invasion depth of early gastric cancer (EGC), the prediction accuracy of EUS is significantly decreased when EGC is combined with ulceration. The aim of present study was to compare the accuracy of EUS and conventional endoscopy (CE) for determining the depth of EGC. In addition, the various clinic-pathologic factors affecting the diagnostic accuracy of EUS, with a particular focus on endoscopic ulcer shapes, were evaluated. We retrospectively reviewed data from 236 consecutive patients with ulcerative EGC. All patients underwent EUS for estimating tumor invasion depth, followed by either curative surgery or endoscopic treatment. The diagnostic accuracy of EUS and CE was evaluated by comparing the final histologic result of resected specimen. The correlation between accuracy of EUS and characteristics of EGC (tumor size, histology, location in stomach, tumor invasion depth, and endoscopic ulcer shapes) was analyzed. Endoscopic ulcer shapes were classified into 3 groups: definite ulcer, superficial ulcer, and ill-defined ulcer. The overall accuracy of EUS and CE for predicting the invasion depth in ulcerative EGC was 68.6% and 55.5%, respectively. Of the 236 patients, 36 patients were classified as definite ulcers, 98 were superficial ulcers, and 102 were ill-defined ulcers, In univariate analysis, EUS accuracy was associated with invasion depth (P = 0.023), tumor size (P = 0.034), and endoscopic ulcer shapes (P = 0.001). In multivariate analysis, there is a significant association between superficial ulcer in CE and EUS accuracy (odds ratio: 2.977; 95% confidence interval: 1.255–7.064; P = 0.013). The accuracy of EUS for determining tumor invasion depth in ulcerative EGC was superior to that of CE. In addition, ulcer shape was an important factor that affected EUS accuracy. PMID:27472672

    Helicobacter pylori is associated with peptic ulcer disease and gastric cancer. Therefore we wanted to test how various lengths of delays in H pylori eradication therapy influence the risk of recurrent peptic ulcer, ulcer adverse events, and gastric cancer. This population-based nationwide Swedish cohort study included 29,032 patients receiving H pylori eradication therapy after peptic ulcer disease in 2005 to 2013. Predefined time intervals between date of peptic ulcer diagnosis and date of eradication therapy were analyzed in relation to study outcomes. Cox regression provided hazard ratios (HRs) and 95% confidence intervals (95% CIs), adjusted for age, sex, comorbidity, history of ulcer disease, use of ulcerogenic drugs, and use of proton pump inhibitors (PPIs). Compared with eradication therapy within 7 days of peptic ulcer diagnosis, eradication therapy within 8 to 30, 31 to 60, 61 to 365, and >365 days corresponded with HRs of recurrent ulcer of 1.17 (95% CI, 1.08-1.25), 2.37 (95% CI, 2.16-2.59), 2.96 (95% CI, 2.76-3.16), and 3.55 (95% CI, 3.33-3.79), respectively. The corresponding HRs for complicated ulcer were 1.55 (95% CI, 1.35-1.78), 3.19 (95% CI, 2.69-3.78), 4.00 (95% CI, 3.51-4.55), and 6.14, (95% CI, 5.47-6.89), respectively. For gastric cancer the corresponding HRs were .85 (95% CI, .32-2.23), 1.31 (95% CI, .31-5.54), 3.64 (95% CI, 1.55-8.56), and 4.71 (95% CI, 2.36-9.38), respectively. Delays in H pylori eradication therapy after peptic ulcer diagnosis time-dependently increase the risk of recurrent ulcer, even more so for complicated ulcer, starting from delays of 8 to 30 days.

    Full Text Available Background: Peptic ulcer makes reference to the solution of continuity of gastric or duodenal wall beyond muscularis mucosae. Previously, duodenal location was more common than gastric, in a ratio ranging from 2:1 to 4:1. Despite this, after the discovery of the association between peptic ulcer and Helicobacter pylori, relationship between gastric and duodenal ulcer has spread to the equality. However, in areas with high incidence of gastric cancer, peptic ulcer seems to have a different behavior, existing predominance of gastric ulcer. Department of Cauca is have the highest incidence of gastric cancer in Colombia, with an annual rate of 42.5 /100,000 for males and 28.6 / 100,000 for women; however, it is unknown how peptic ulcer anatomically are distributed. Objective: To determine the anatomical distribution of peptic ulcer at endoscopy service of San José University Hospital of Popayán-Cauca, Colombia 2006-2012. Methods: A descriptive cross-sectional study was realized. Database of endoscopy service of San José University Hospital of Popayán was reviewed and reports with diagnosis of peptic ulcer were studied. Data were analyzed using SPSS-15. Results: Gastric ulcer was more common than duodenal ulcer. Gastric ulcer was more common in men (gastric and duodenal ulcer 1:1. In women duodenal ulcer is 1:1. Conclusion: At endoscopy service of San José University Hospital, gastric ulcer is more common than duodenal ulcer, with differences in gender, as in other areas with high incidence of gastric cancer. That fact are suggests in current literature could be related with the presence of stumps of Helicobacter pylori with combined virulence for cancer and ulcer at gastric level seems to be related to the presence in the medium of common virulence strains of Helicobacter pylori for stomach cancer and ulcer gastric, although the current literature is unclear about it, and still needs more validations.

    The discovery that Helicobacter pylori infection is the major cause of peptic ulcer disease revolutionised our views on the etiology and treatment of the disease. This discovery has tempted many experts to conclude that psychological factors and, specifically, stress are unimportant. However, Helicobacter pylori infection alone does not explain fully the incidence and prevalence of peptic ulcer disease. It has been demonstrated that stress can cause peptic ulcer disease even in the absence of Helicobacter pylori infection, supporting a multicausal model of peptic ulcer etiology. Psychological stress among other risk factors can function as a cofactor with Helicobacter pylori infection.

    The involvement of the H1 and H2 receptors for histamine in the pathogenesis of gastric ulcers was investigated in rats. Metiamide, an H2 receptor antagonist, reliably reduced ulceration produced by stress alone or by a combination of stress and aspirin. In contrast, pyrilamine, which blocks only the H1 receptor, was without effect under these same conditions. The results support the hypothesis that histamine mediates both stress and stress plus aspirin induced ulceration by a mechanism involving the H2 receptor.

    During an X-ray study the niche symptom was established in 244 patients with peptic ulcer. The X-ray findings were compared with those of gastroduodenofibroscopy (GDFS) in 111 patients (45.5 %), and with those of operation in 84 (34.2 %). By the operative findings X-ray and GDFS results coincided in all cases of gastric ulcer. With ulcer in the pyloroduodenal zone, X-ray errors were found in 2 (2.3 %) patients whereas in GDFS in 8(5.8 %). The X-ray method was shown to be the most important in the diagnosis of penetration and stenosis of ulcer. The tactics of a roentgenoendoscopic study in peptic ulcer should be based on the diagnostic potentialities of these methods taking a stage into account

    There is an enigma of inflammatory bowel diseases, despite significant advantages during last 10 years in medicamentous and surgical treatment. Ulcerative colitis and Crohns disease are chronic with remissions and recidives. Crohns disease involves any part of digestive tube. Histological changes in ulcerative colitis are: inflammation of mucosa and submucosal tissue, crypt abscesses and ulcerations, pseudopolpys, bowel shortening and toxic megacolon in severe inflammation. In Crohns disease, transmural inflammation, "jumping lesions", deeper ulcerations, coble-stone mucosa, progressive fibrosis, granuloma with gigantic epithelial cells. ulcerative colitis: mesalazine, rectal 5-ASA and hydrocortisone enemas, surgery. Crohns disease: mesalazine and prednisolone. For terminal ilcitis, corticosteroid budesonid could be applied. Severe symptomatic disease: hospitalization, parenteral nutrition, antibiotics, prednisone, surgery in partial bowel obstruction, fistulas, abscessus, perforation.

    To evaluate the usefulness of transabdominal ultrasonography as a screening examination in patients with suspicious gastric disease. We selected 141 patients with epigastric pain and who were found to have antral gastric wall thickening of more than 5 mm in transabdominal ultrasonography, and who underwent gastroscopy immediately following the ultrasonography examination, because we suspected that these patients had gastric disease. We measured the full thickness of the five layers of the gastric wall and evaluated the preservation of this five layered structure. We respectively compared the gastric wall thickness and the preservation of gastric layers in 26 normal, 91 gastritis, 12 gastric ulcer, and 12 gastric cancer patients, who were classified based on the gastroscopy results. The mean thicknesses of the gastric wall in the normal, gastritis, gastric ulcer and gastric cancer patients were 5.13{+-}0.14 mm, 6.71{+-}1.33 mm, 8.08{+-}2.80 mm, and 12.45{+-}3.70 mm, respectively. The gastric walls in the gastritis, gastric ulcer and gastric cancer patients were significantly thicker than that in the normal patients (p < 0.01). The gastric wall in the gastric cancer patients was significantly thicker than those in the gastritis and gastric ulcer patients (p < 0.01). However, the difference in the gastric wall thickness between the gastritis and gastric ulcer patients was not statistically significant (p > 0.01). Except for two patients with gastritis and three patients with gastric ulcer, the stratification of the gastric wall was preserved in all of the normal, gastritis and gastric ulcer patients, whereas it was disrupted in all of the patients with gastric cancer. Transabdominal ultrasonography in the fasting state may be a helpful and convenient modality, which can serve as a screening examination in the evaluation of gastric disease. Therefore, careful attention and effort are needed to evaluate the gastric wall during transabdominal ultrasonography

    As fistula occurring between the stomach and other abdominal internal organs or to the surface of the body is usually encountered as a complication of stomach cancer or colon cancer, peptic ulcer disease, or other variable causes. The most common type of gastric fistula is a gastro-colic fistula that is mainly found as a complication of a gastric carcinoma or of a carcinoma of the transverse colon invading each other. Sometimes, a benign gastric ulcer perforation also can cause a gastro-colic fistula. However, as far as we know, a fistula occurring between the stomach and the umbilicus has not been reported. Here we present a case report of a gastro-umbilical fistula in a young woman that manifested as a umbilical discharge.

    This study is to analyze gastric emptying (GE) of 99m Tc tagged solid meals in 43 gastric ulcer (GU), 16 duodenal ulcer (DU) patients, and 15 normal subjects. Diagnosis of active ulcers had been made through high gastrointestinal endoscopy. The patients with GU were divided in three groups according to Johnson's classification. Gastric contents were measured at 15 minutes intervals over a period of 150 minutes, with the person standing in front of a gamma-counter. The ge curve was obtained from the mean percentile of radioactive of all the groups measured at 15 minutes intervals. results were submitted to statistical analysis. Significant delay in GE in DU patients compared to normals, type II and type III group. However, GE of type I GU was not statistically different from the DU group nor of types II and III, occupying an intermediate e position. (author)

    Ibuprofen is the first line of treatment for osteoarthritis and arthritis. The main side effects of ibuprofen especially in long-term treatment include gastric ulcer, duodenal ulcer and indigestion etc. Therefore, screening drugs with effective gastric protective effects and low toxicity for combination therapy with ibuprofen is necessary. The mechanism of gastric damage induced by ibuprofen is still unclear, however, cell damage caused by reactive oxygen species (ROS) is considered as the main reason. Preliminary screening of literature with the criteria of low toxicity led to four histamine-2 receptor antagonists (H2RAs): nizatidine, famotidine, lafutidine, and roxatidine acetate, which were selected for further investigation. These drugs were evaluated systemically by examining the gastric ulcer index, lipid peroxidation (LPO), membrane permeability, toxicity to main organs, and the influence on the activity of antioxidant enzymes, and myeloperoxidase (MPO). Nizatidine was found to be the best gastric protective agent. It exhibited excellent protective effect by increasing antioxidant enzyme activity, decreasing MPO activity, reducing LPO, and membrane permeability. Combination treatment with nizatidine and ibuprofen did not show any significant toxicity. Nizatidine was considered as a good option for combination therapy with ibuprofen especially for diseases that require long-term treatment such as arthritis and osteoarthritis.

    Cardiovascular disease is the most important cause of morbidity and mortality in the world and low-dose aspirin is considered the cornerstone of the cardiovascular disease prevention. However, low-dose aspirin use is associated with gastrointestinal adverse effects in the whole gastrointestinal tract. In this setting, co-therapy with a proton pump inhibitor is the most accepted strategy to reduce aspirin related upper gastrointestinal damage. In addition, some adverse effects have been described with proton pump inhibitors long term use. Areas covered: Low-dose aspirin related beneficial and adverse effects in cardiovascular system and gastrointestinal tract are reviewed. In addition, this manuscript summarizes current data on upper gastrointestinal damage prevention and adverse events with proton pump inhibition. Finally, we discuss the benefit/risk ratio of proton pump inhibitor use in patients at risk of gastrointestinal damage taking low-dose aspirin. Expert commentary: Nowadays, with the current available evidence, the combination of low-dose aspirin with proton pump inhibitor is the most effective therapy for cardiovascular prevention in patients at high gastrointestinal risk. However, further studies are needed to discover new effective strategies with less related adverse events.

    Gastric ulcer is a common chronic disease in human digestive system, which is difficult to cure, easy to relapse, and endangers human health seriously. Compared with western medicine, traditional Chinese medicine has a unique advantage in improving the general situation, stablizing medical condition, and with little side effects. Glycyrrhiza known as "king of all the medicine", has a range of pharmacological activities and is commonly used in a variety of proprietary Chinese medicines and formulations. On the basis of explicit antiulcer effect of Glycyrrhiza triterpenes, the molecular mechanisms of its therapeutic effect on acetic acid induced gastric ulcer in rats were explored. Acetic acid induced gastric ulcer model in rats was established to evaluate the curing effect of G. triterpenes and all of the rats were randomised into six groups: Control group, model group, omeprazole group (0.8 mg/mL), triterpenes high dose group (378.0 mg/mL), triterpenes middle dose group (126.0 mg/mL), and triterpenes low dose group (42.0 mg/mL). All rats in groups were orally administered the active group solution 1.5 mL once daily (model and control groups with saline) for 7 days. HPLC-TOF-MS analysis method was performed to obtain the plasma metabolites spectrums of control group, model group, triterpenes high, middle and low dose groups. A total of 11 differential endogenous metabolites related to the therapeutic effect of G. triterpenes were identified, including tryptophan, phingosine-1-phosphate, pantothenic acid, and so on, among which tryptophan and phingosine-1-phosphate are related with the calcium signaling pathway and arachidonic acid (AA) metabolism. At the same time, in order to verify the above results, quantitative real time polymerase chain reaction were performed to evaluate the expression of H + -K + -ATPase alpha mRNA and phospholipase a 2 mRNA in relational signaling pathways. Combined with statistical analysis of plasma metabolic spectrum and gene expression

    Peptic ulcer predicts gastric cancer. It is controversial if peptic ulcers predict other gastrointestinal cancers, potentially related to Helicobacter pylori or shared lifestyle factors. We hypothesized that gastric and duodenal ulcers may have different impact on the risk of gastrointestinal cancers. In a nationwide cohort study using Danish medical databases 1994-2013, we quantified the risk of gastric and other gastrointestinal cancers among patients with duodenal ulcers (dominantly H. pylori-related) and gastric ulcers (dominantly lifestyle-related) compared with the general population. We started follow-up 1-year after ulcer diagnosis to avoid detection bias and calculated absolute risks of cancer and standardized incidence ratios (SIRs). We identified 54,565 patients with gastric ulcers and 38,576 patients with duodenal ulcers. Patient characteristics were similar in the two cohorts. The 1-5-year risk of any gastrointestinal cancer was slightly higher for gastric ulcers patients (2.1%) than for duodenal ulcers patients (2.0%), and SIRs were 1.38 (95% CI: 1.31-1.44) and 1.30 (95% CI: 1.23-1.37), respectively. The SIR of gastric cancer was higher among patients with gastric ulcer than duodenal ulcer (1.92 vs. 1.38), while the SIRs for other gastrointestinal cancers were similar (1.33 vs. 1.29). Compared with gastric ulcer patients, duodenal ulcer patients were at lower risk of smoking- and alcohol-related gastrointestinal cancers. The risk of nongastric gastrointestinal cancers is increased both for patients with gastric ulcers and with duodenal ulcers, but absolute risks are low. H. pylori may be less important for the development of nongastric gastrointestinal cancer than hypothesized. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    Full Text Available Cocaine or Benzoylmethylecgonine is an alkaloid extracted from the leaves of the Erythroxylon plant, which can cause gastrointestinal ischemia from severe arterial vasoconstriction via stimulation of alpha-adrenergic receptors in the gastric and mesenteric arteries. We report this case of a 65-year-old man who presented with a single massive ulcer at the incisura of the stomach as a result of cocaine use. The size and location of this ulcer were atypical and illustrate the potential for serious gastrointestinal manifestations from cocaine use.

    A previous work suggests that sucralfate labeled by binding to Tc-99m HSA permits the visualization of gastric ulcers. Potential problems with this technique are: 1) decreased binding of sucralfate to ulcer sites due to the labeling method of binding to exogenous protein (HSA); 2) overlying activity that may obscure identification of the ulcer. Because of these problems we have examined the possibility of direct in vivo Tc-99m labeling of sucralfate after it has already bound to the ulcer. In vitro studies were done to determine the binding of Tc-99m pertechnetate to sucralfate in the presence of tin in HCl solution at pHs comparable to those found in the stomach. Rapid and efficient labeling was achieved with 75-95% of the label bound to sucralfate at 30 minutes. In vivo studies were performed in rabbits with aspirin induced ulcers and in ulcer free human volunteers. The animal studies confirm that orally administered Tc-99m pertechnetate will bind to previously ingested sucralfate and that the labeled material will bind to the ulcers. Tc-99m pertechnetate was also shown to bind well to previously ingested sucralfate in humans. The results suggest that it is possible to label sucralfate in vivo. This method would offer the following advantages: 1) a simpler labeling procedure; 2) the potential of increased sensitivity by delaying the labeling until much of the sucralfate not bound to ulcer has passed, and thus decreasing the activity that remains in the stomach; and also by leaving the protein binding sites of the sucralfate free to interact with the ulcer since no exogenous protein is involved in labeling

    Healing of heel ulcers in patients with diabetes is considered to be poor, but there is relatively little information on the influence of ulcer location on ulcer healing. The influence of ulcer location on time to healing of diabetic foot ulcers was analysed by multivariate Cox regression analysis for 1000 patients included in the Eurodiale study, a prospective cohort study of patients with diabetic foot disease. Median time to healing was 147 days for toe ulcers [(95% confidence interval (CI) 135-159 days)], 188 days for midfoot ulcers (95% CI 158-218 days) and 237 days for heel ulcers (95% CI 205-269 days) (p ulcers was 172 days (95% CI 157-187 days) and 155 days (95% CI 138-172 days) for nonplantar ulcers (p = 0.71). In multivariate Cox regression analysis, the hazard ratio for ulcer healing for midfoot and heel ulcers compared with toe ulcers was 0.77 (95% CI 0.64-0.92) and 0.62 (95% CI 0.47-0.83), respectively; the hazard ratio for ulcer healing for plantar versus nonplantar ulcers was 1 (95% CI 0.84-1.19). Other factors significantly influencing time to healing were the duration of diabetes, ulcer duration, the presence of heart failure and the presence of peripheral arterial disease. Time to ulcer healing increased progressively from toe to midfoot to heel, but did not differ between plantar and nonplantar ulcers. Our data also indicate that risk factors for longer time to healing differ from factors that affect the ultimate number of ulcers that heal (healing rate). Copyright © 2013 John Wiley & Sons, Ltd.

    Patients with upper abdominal pain are often examined with both double contrast study of the stomach and endoscopy. On the basis of the results of the two examinations four diagnostic criteria of an ulcer can be formed: 1) radiography reveals an ulcer, 2) endoscopy reveals an ulcer, 3) both radiography and endoscopy reveal an ulcer, and 4) radiography and/or endoscopy reveals an ulcer. In a prospective study the accuracy of each of the four diagnostic criteria was examined. Eighty-two randomly selected outpatients had a double contrast barium examination and an upper gastrointestinal endoscopy performed by staff personnel. The diagnosis of a specialist in upper gastrointestinal endoscopy was used as the standard. For the four diagnostic criteria the overall accuracy ranged from 0.80 to 0.88. The predictive value of a positive test result was around 0.70 and the predictive value of a negative test result ranged from 0.81 to 0.96. The specificity ranged from 0.87 to 0.95, and the sensitivity from 0.38 to 0.90. It is concluded that from a clinical point of view, the accuracy of the four diagnostic criteria does not differ to an extent that justifies recommendation of one diagnostic criterion of gastric ulcer rather than the other.

    Hormonal fluctuations are known to predispose ulceration of the upper gastrointestinal tract, but to date no comparative study of their effects on the healing of pre-existing ulcers in the oral cavity and stomach has been made. We studied the effects of depletion of testosterone and of EGF on the healing of acetic acid-induced ulcers using rats having undergone bilateral orchidectomy and/or salivectomy respectively. We measured alterations in gastric acid secretion and blood flow at ulcer margins, as well as plasma levels of testosterone, gastrin and the proinflammatory cytokines IL-1 beta and TNF-alpha. Testosterone (0.01-10 mg/kg/day i. m.) dose-dependently delayed oral and gastric ulcer healing. When applied in an optimal dose of 1 mg/kg/day, this hormone significantly raised gastric acid secretion and plasma IL-1 beta and TNF-alpha levels. Attenuation of plasma testosterone levels via bilateral orchidectomy inhibited gastric acid secretion and accelerated the healing of oral and gastric ulcers, while increasing plasma gastrin levels and these effects were reversed by testosterone. Salivectomy raised plasma testosterone levels, and delayed oral and gastric ulcer healing. Treatment of salivectomised animals with testosterone further inhibited ulcer healing, and this effect was counteracted by EGF. We propose that testosterone delays ulcer healing via a fall in blood flow at the ulcer margin, a rise in plasma levels of IL-1 beta and TNF-alpha and, in the case of gastric ulcers, an increase in gastric acid secretion. EGF released from the salivary glands plays an important role in limitation of the deleterious effects of testosterone on ulcer healing.

    The aim of our study is to investigate EGF content in biological mediums in children with duodenum ulcer depending on phase of the disease and different variants of its course. The present study was performed in Federal State Establishment "Nizhniy Novgorod Research Institute of Children Gastroenterology", Nizhniy Novgorod, Russia. 92 children, between the ages of 8 to 17, with duodenum ulcer were under observation. Endoscopy was performed by Pentax endoscope (FG-24V). EGF detection was performed in blood serum, gastric juice and saliva by ELISA method with Human EGF Kit, "Invitrogen", USA. The peculiarities of EGF level changes in human biological mediums, depending on phase of the disease. The highest EGF level was detected with acute peptic ulcer in the presence of ulcerous defects. EGF level increasing was marked out in the remission phaseas ulcerous defects healing, and it didn't reach normal values in gastric juice. EGF content changes in biological mediums were revealed with different variants of duodenum ulcer clinical course in children. The lowest EGF level was marked out in blood, saliva and gastric juice with unfavorable course of the disease (frequent relapses, cicatricial-ulcerous strains formation), which can serve as a prognostic factor.

    Helicobacter pylori (H. pylori) infection is an established cause of peptic ulcers and gastric cancer. The aim of this study was to identify H. pylori genotypes and to examine their associations with geographical regions and gastritis, peptic ulcers and gastric cancer in Laos. A total of 329 Lao dyspeptic patients who underwent gastroscopy at Mahosot Hospital, Vientiane, Laos during December 2010--March 2012 were enrolled. Two biopsy specimens (one each from the antrum and corpus) were obtained for CLO testing and only CLO test-positive gastric tissue were used to extract DNA. PCR and sequencing were identified for variants of the cagA and vacA genotypes. Some 119 Laos patients (36.2%) were found to be infected with H. pylori including 83 with gastritis, 13 with gastric ulcers (GU), 20 with duodenal ulcers (DU) and 3 with gastric cancer. cagA was detected in 99.2%. East-Asian-type cagA (62%) and vacA s1c (64.7%) were predominant genotypes in Laos. vacA s1c-m1b was significantly higher in GU than gastritis (53.8% vs. 24.1%; P-value=0.04) whereas vacA s1a-m2 was significantly higher in DU than gastritis (40.0% vs. 16.9%; P-value=0.03). East-Asian-type cagA and vacA s1c were significantly higher in highland than lowland Lao (100% vs. 55.8%; P-value=0.001 and 88.2% vs. 61.5%, P-value=0.03 respectively). H. pylori is a common infection in Laos, as in other countries in Southeast Asia. The cagA gene was demonstrated in nearly all Laos patients, cagA and vacA genotypes being possible important factors in explaining H. pylori infection and disease outcomes in Laos.

The gastroprotective effect of C. barometz leaves against ethanol-induced gastric hemorrhagic abrasions in Sprague Dawley rats has been evaluated in terms of medicinal properties. Seven groups of rats (normal control and ulcerated control groups, omeprazole 20 mg/kg, 62.5, 125, 250, and 500 mg/kg of C. barometz correspondingly were used in antiulcer experiment and pretreated with 10% Tween 20. After 1 hour, the normal group was orally administered 10% Tween 20, whereas absolute alcohol was fed orally to ulcerated control, omeprazole, and experimental groups. Gastric’s homogenate were assessed for endogenous enzymes activities. Stomachs were examined macroscopically and histologically. Grossly, the data demonstrated a significant decrease in the ulcer area of rats pretreated with plant extract in a dose-dependent manner with respect to the ulcerated group. Homogenates of the gastric tissue exhibited significantly increased endogenous enzymes activities in rats pretreated with C. barometz extract associated with the ulcerated control group. Histology of rats pretreated with C. barometz extract group using hematoxylin and eosin staining exhibited a moderate-to-mild disruption of the surface epithelium with reduction in submucosal edema and leucocyte infiltration in a dose-dependent manner. In addition, it showed heat shock protein70 protein up-expression and BCL2-associated X protein downexpression. These outcomes might be attributed to the

    Gastric ulcer is a common disorder of the digestive system. Current therapeutic regimens largely rely on Western medicine. However, numerous studies have demonstrated that herbal medicines can effectively treat gastric ulcer in humans and various animal models via divergent mechanisms. This review updates the efficacy and safety of herbal medicines in treating gastric ulcer, and the mechanisms of their action in humans and animal models. Studies have demonstrated that the efficacy of herbal medicines is comparable or superior to that of drugs such as omeprazole or cimetidine in humans and animal models, and herbal medicines display fewer adverse effects. The mechanisms by which herbal medicines benefit gastric ulcer include stimulation of mucous cell proliferation, anti-oxidation, and inhibition of gastric acid secretion and H(+)/K(+)-ATPase activity. Some herbal medicines also exhibit antimicrobial properties. Utilization of herbal medicines could be a valuable alternative to treat gastric ulcer in humans effectively, with few adverse effects.

    The effect of omeprazole and cimetidine on healing of chronic gastric ulcers and gastric acid secretion was investigated in rats. The effect of three doses of omeprazole given orally once daily for 25 days was investigated. In controls median ulcer healing was 19.6% after 25 days. Omeprazole...... increased median ulcer healing from 36% at 145 mumole/kg/day to 80% at 580 mumole/kg/day. Basal and pentagastrin stimulated gastric acid secretion decreased dose-dependently by nearly 90% at a dose of 580 mumole/kg/day 22-24 hr after the last dose of omeprazole. Cimetidine given twice daily, in a dose...... that initially inhibits gastric acid secretion by 95%, reduced acid secretion by only 50% 11 hr after the last dose. Median ulcer healing after treatment with cimetidine for 25 days was 41%. This study demonstrates that omeprazole has a more long-acting inhibitory effect on gastric acid secretion compared...

    Full Text Available Background/Aim. Gastric ulcer may be benign or malignant. In terms of therapy and patient’s prognosis early detection of malignancy is very important. The aim of this study was to assess the usefulness of endoscopic ultrasound (EUS in differentiation between benign and malignant gastric ulcer. Methods. A prospective study included 20 consecutive adult patients with malignant gastric ulceration and 20 consecutive adult patients with benign gastric ulceration. All the patients underwent EUS. A total of 6 parameters were analyzed: ulcer width, ulcer depth, the thickness of the gastric wall along the edge of ulceration (T0, the thickness of the gastric wall 2 cm from the edge of ulceration (T2, loss of layering structure of the gastric wall, and the presence of regional lymph nodes. EUS criteria for malignancy and a point-score of malignancy were defined. The critical value of total point-score was also calculated showing the best reliability parameters. Results. There are 4 criteria for malignancy of gastric ulceration: T0 > 10 mm, T2 > 5 mm, EUS visualization of at least one lymph node, loss of layering structure of the gastric wall. Furthermore, T2 > 5 mm was the only EUS independent predictor of ulcer malignancy. The total point score of ≥ 4 was the cut-off pointscore value which gave the best reliability parameters in the assessment of malignant ulcers: sensitivity of 70%, specificity of 95%, positive predictive value of 93.3%, negative predictive value of 76% and accuracy of 82.5%. Conclusion. According to the results obtained in this study, we can conclude that EUS is usefull in differentiation between benign and malignant gastric ulcer.

    The risk of dying from gastric cancer appears to have increased among consecutive generations born during the 19th century. To follow the time trends of hospitalization for gastric cancer and test whether they confirm such increase. Inpatient records of the last two centuries from four hospitals in Scotland and three US hospitals were analysed. Proportional rates of hospitalization for gastric cancer, gastric ulcer and duodenal ulcer were calculated during consecutive 5-year periods. The data from all seven cities revealed strikingly similar patterns. No hospital admissions for gastric cancer or peptic ulcer were recorded prior to 1800. Hospital admissions for gastric cancer increased in an exponential fashion throughout the 19th and the beginning of the 20th century. In a majority of cities, the rise in hospitalization for gastric cancer preceded a similar rise in hospitalization for gastric ulcer. Hospitalization for these two latter diagnoses clearly preceded hospitalization for duodenal ulcer by 20-40 years. The occurrence of gastric cancer, gastric ulcer and duodenal ulcer markedly increased during the 19th century. Improvements in hygiene may have resulted in the decline of infections by other gastrointestinal organisms that had previously kept concomitant infection by Helicobacter pylori suppressed.

    Selenium, a trace element, in the form of sodium selenite has been studied for its ability to protect the gastric mucosa against the injuries caused by hypothermic restraint stress, aspirin, indomethacin, reserpine, dimaprit, and various other gastric mucosal-damaging (necrotizing) agents in rats. The results demonstrate that oral administration of sodium selenite produces a significant inhibition of the gastric mucosal damage induced by all the procedures used in this study. Selenium, in a nonantisecretory dose, produced a marked cytoprotective effect against all the necrotizing agents. The cytoprotective effect of selenium against the effects of 80% ethanol and 0.6 M HCl was significantly reversed by prior treatment with a dose of indomethacin that inhibits prostaglandin biosynthesis. These data indicate that sodium selenite inhibits the formation of these lesions by the mucosal generation of prostaglandins. The concentrations of nonprotein sulfhydryls (NP-SH) were significantly decreased in the gastric mucosa following the administration of necrotizing agents--80% ethanol and 0.6 M HCl. Treatment with sodium selenite, which significantly reduced the intensity of gastric lesions, did not replenish the reduced levels of gastric mucosal NP-SH, thus ruling out the mediation of its protective effect through sulfhydryls. The antisecretory effect of sodium selenite, which becomes evident only in the high dose of 20 mumol/kg, may be responsible for the inhibition of gastric lesions induced by aspirin, indomethacin, reserpine, and dimaprit. Our findings show that selenium possesses significant anti-ulcer and adaptive cytoprotective effects. However, further detailed studies are required to confirm these effects, to establish its mechanism(s) of action, and to determine its role in the prophylaxis and treatment of peptic ulcer disease.

    The purpose of this study was to evaluate MDCT parameters for differentiating malignant (category T1 and T2) from benign gastric ulcers and to evaluate the performance characteristics of these predictors with optimal cutoff points determined in receiver operator characteristic analysis. The subjects were 26 patients with gastric cancer (11 with T1 lesions, 15 with T2 lesions) and 26 patients with benign gastric ulcer. MDCT and virtual gastroscopic findings were analyzed according to four qualitative criteria: ulcer shape, base, and margin and changes in adjacent folds. The quantitative criteria ulcer size, thickness of the gastric wall around an ulcer, thickness of the enhanced ulcer base, and enhancement around an ulcer were measured on multiplanar reconstruction images. We calculated the sensitivity and specificity of each quantitative criterion. Receiver operator characteristic analysis was used to identify cutoff points yielding optimal sensitivity and specificity for the diagnosis of gastric cancer. On virtual gastroscopy, ulcer shape and margin and gastric fold changes had sensitivities of 80.8%, 84.6%, and 90.9% and specificities of 76.9%, 73.1%, and 77.8%, respectively, in the diagnosis of gastric cancer. On multiplanar reconstruction images, thickness of the enhanced ulcer base and enhancement around the ulcer had sensitivities of 80.8% and 73.1% and specificities of 100% and 100%. MDCT combined with virtual gastroscopy and multiplanar reconstruction enhances the morphologic details of gastric ulcers and is a useful way to differentiate malignant (T1 and T2) and benign gastric ulcers.

    Therapeutic gastric irradiation has been used to reduce peptic juice secretion in patients with peptic ulcer disease. Between 1937 and 1968 a total of 2049 patients received such therapy at the University of Chicago. Three of these patients are known to have developed sarcomas in the field of radiation. Two gastric leiomyosarcomas of the stomach were diagnosed 26 and 14 years after treatment and a malignant fibrous histiocytoma of the anterior chest wall was removed six years after gastric irradiation. Of 743 peptic ulcer patients treated without irradiation and constituted as a control group for the study of therapeutic gastric radiation, none is known to have developed sarcoma. As the incidence of sarcoma in these patient groups is known only from the tumor registry of the University of Chicago, other cases of sarcoma may exist in the groups. While an increased incidence of sarcoma has not been proven to occur in patients who received therapeutic gastric irradiation for peptic ulcer disease, the possibility of such a risk should be borne in mind by physicians caring for such patients.

    The purpose of this study was to evaluate three radiolabels for the drug Carafate (basic aluminum sucrose octasulfate), which, when ingested orally, is believed to coat gastric ulcers and protect them from digestive enzymes to promote healing. In order to study the mode of action and residence time in the stomach using external imaging, a gamma-emitting label which is truly bound to the molecule is needed. Carafate has been radiolabeled with Se-75, In-111 (both chemically incorporated into the molecule) and with Tc-99m-HSA which physically adheres to Carafate. In the presence of stomach acid, Carafate polymerizes; when the labeled Carafates were mixed in vitro with 0.1N HCl, >90% of the radio-activity was associated with the polymer in the case of Se-75 and Tc-99m, but the In-111 label was less stable (25-35% bound to polymer). The three labeled preparations were administered orally to rats with gastric ulcers, and the transit of each was followed by gamma camera imaging. Gamma camera images confirmed radioactivity remaining at the ulcer site after unbound material had emptied from the stomach, and the focal activity persisted for >5 hours. The stomachs were then removed, washed and dissected at 5.5 hours and in vitro measurements of ulcer crater: normal stomach tissue radioactivity ratios averaged 15.4, 6.3, and 5.6 for the Se-75, In-111, and Tc-99m-HSA labels, respectively. Biodistribution studies of oral Se-75-Carafate in rats and pigs indicated that very little is absorbed from the GI tract and the distribution is similar to that of C-14-Carafate. It is concluded that Se-75 is the best marker for Carafate of these three gamma-emitting labels and Se-75-Carafate is suitable for studying the kinetics of the drug Carafate in human subjects

    2009-01-01

    The anti-ulcerogenic activity of propolis or bee glue, a natural product from honey bees, was investigated against indomethacin -induced gastric ulcers in non- irradiated and irradiated rats, and the effects were compared with those of the proton pump inhibitor lansoprazole, as a reference anti-ulcerogenic drug. Indomethacin-induced gastric ulcer was used in this study as a model of experimentally induced gastric ulceration. The anti-ulcerogenic, antisecretory and cytoprotective activities of 13% aqueous propolis extract (APE) were assessed. Gastric contents of animals were sampled for the measurement of free acidity, acid output, mucin and pepsin concentrations in the gastric juice. The stomach was examined macroscopically for the determination of the ulcer index. PGE 2 was assayed in the gastric mucosa, while the pro-inflammatory cytokines TNF-α and IL-1β as well as the oxidative stress marker MDA were determined in the plasma.

    AIMS Whether corticosteroids induce peptic ulcer disease (PUD) remains uncertain. The study evaluated and compared the occurrence of PUD between nephrotic patients receiving oral prednisolone therapy and nephritic patients without steroid therapy. METHODS The prospective case control study compared 60 nephrotic syndrome patients who received 60 mg daily prednisolone therapy for 3 months with 30 age-and sex-matched nephritic patients without steroid therapy. Each patient underwent endoscopic examination and tissue and blood sampling before and after the study. Examined parameters included Helicobacter pylori (H. pylori) infection, and gastric and serum prostaglandin (PG) E2 and thromboxane (TX) B2 concentrations. The primary endpoint was the occurrence of endoscopic peptic ulcers between the two groups, while the secondary end point was the occurrence of ulcer complications. RESULTS The two groups were comparable in sex, age, smoking habits, alcohol drinking, past history of PUD, H. pylori infection rate and serum creatinine. There were no differences in the occurrence of endoscopic peptic ulcers (1.6% vs. 3.3%) and ulcer complications (0% vs. 0%), pre-therapy gastric PGE2, and pre- and post-therapy gastric TXB2, serum PGE2 and serum TXB2 between the two groups. However, there was significantly lower post-therapy gastric PGE2 concentrations in the prednisolone group. CONCLUSIONS Three-month therapy with 60 mg daily prednisolone caused few endoscopic ulcers (1.6%) and no ulcer complications in nephrotic patients. Corticosteroids therapy did not increase PUD in nephrotic syndrome patients [odds ratio 0.492 with 95% confidence interval (CI) 0.03, 8.142, P= 0.620]. Further larger studies are needed to clarify the role of corticosteroids in PUD.

    Full Text Available Objectives Endoscopic submucosal dissection (ESD is useful for treating gastric tumors. Several trials have shown the efficacy of 4 or 8 weeks of proton pump inhibitor (PPI administration for post-ESD ulcers. However, if the size of the post-ESD ulcer is larger than predicted, PPI administration alone might not be sufficient for the ulcer to heal within 4 weeks. There is no report about the efficacy of post-ESD gastric ulcers by esomeprazole. We examined retrospectively the efficacy of a combination therapy of esomeprazole plus rebamipide, a mucosal-protective antiulcer drug, on the acceleration of post-ESD ulcer healing comparing with omeprazole plus rebamipide. Methods We reviewed the medical records of patients who underwent ESD for gastric neoplasia. We conducted a case-control study to compare the healing rates within 4 weeks effected by esomeprazole plus rebamipide (group E and omeprazole plus rebamipide (group O. The sizes of the artificial ulcers were divided into normal-sized or large-sized. Results The baseline characteristics did not differ significantly between the two groups except age and sex. Stage S1 disease was observed in 27.6% and 38.7% of patients after 4 weeks of treatment in the group E and O, respectively. In large-sized artificial ulcers, the healing rate of stage S1 in group E is significantly higher than that in group O in 4 weeks.(25% VS 0%: P = 0.02 Conclusions The safety and efficacy profiles of esomeprazole plus rebamipide and omeprazole and rebamipide are similar for the treatment of ESD-induced ulcers. In large-sized ulcers, esomeprazole plus rebamipide promotes ulcer healing.

    The rhizome of Atractylodes lancea (AL, Compositae, Chinese name: Cangzhu; Japanese name: Sou-ju-tsu) has been used traditionally for the treatment of various diseases such as digestive disorders, rheumatic diseases, and influenza in China, Korea and Japan. The crude AL and AL bran-processed are both listed in the Chinese Pharmacopoeia. However, the differences between the effects of the crude and AL bran-processed on gastric ulcer were poorly understood, and the mechanisms for the treatment of gastric ulcer were not clear. This study aimed at comparing the anti-ulcer effects between the crude AL and AL processed in acetic acid induced model in rats and evaluating the mechanisms of action involved in the anti-ulcer properties of AL. The model of gastric ulcer was imitated by acetic acid in rats, and AL was gavaged. The serum and gastric tissues were collected. The levels of epidermal growth factor (EGF), trefoil factor2 (TFF2), tumor necrosis factor-α (TNF-α), interleukin 6, 8 (IL-6, 8) and prostaglandin E2 (PGE2) in serum and gastric tissues were determined by the double-antibody sandwich enzyme-linked immunosorbent assay (ELISA), and the mRNA expressions of EGF, TFF2, TNF-α, and IL-8 in stomach were analyzed by quantitative real-time reverse transcription polymerase chain reaction (RT-PCR). Meanwhile, histopathological changes were evaluated by hematoxylin and eosin (HE) stain. The protein expressions of EGF, TFF2, TNF-α, and IL-8 were examined by immunohistochemistry in stomach. The results demonstrated that the damage of gastric tissue was obviously alleviated and the productions of TNF-α, IL-8, IL-6, and PGE2 and the mRNA expressions of TNF-α, and IL-8 were notably inhibited. Furthermore, the productions of EGF and TFF2 and the mRNA expressions of EGF and TFF2 were significantly stimulated by both crude AL and AL processed in a dose-dependent manner. Compared with the crude AL, the processed AL was more effective. The AL processed had more satisfactory

    Recent data report that the incidence of peptic ulcer is decreasing in the general population; conversely, the rates of gastric and duodenal ulcer hospitalization and mortality remain very high in older patients. Two major factors that might explain this epidemiological feature in the elderly population are the high prevalence of Helicobacter pylori infection and the increasing prescriptions of gastroduodenal damaging drugs, including NSAIDs and/or aspirin (acetylsalicylic acid). The main goals for treating peptic ulcer disease in old age are to reduce recurrence of the disease and to prevent complications, especially bleeding and perforation. The available treatments for peptic ulcer are essentially based on gastric acid suppression with antisecretory drugs and the eradication of H. pylori infection. The aim of this article is to report the available data on clinical efficacy and tolerability of peptic ulcer treatments in elderly patients and provide recommendations for their optimal use in this special population. Proton pump inhibitor (PPI)-based triple therapies for 7 days are highly effective for the cure of H. pylori-positive peptic ulcers as well as for reducing ulcer recurrence. Antisecretory drugs are also the treatment of choice for NSAID- or aspirin-related peptic ulcers and are useful as preventive therapy in chronic users of NSAIDs and low-dose aspirin as antiplatelet therapy. Antisecretory PPI therapy has a favourable tolerability profile in geriatric patients; however, monitoring is suggested in older patients with frequent pulmonary infections, gastrointestinal malabsorption, unexplained chronic diarrhoea, osteoporosis or those taking concomitant cytochrome P450 2C19-metabolized medications. The overall approach to the geriatric patient should include a comprehensive geriatric assessment that ensures multidimensional evaluation of the patient in order to better define the clinical risk of adverse outcomes in the older patient with peptic ulcer and

    Anecdotally, aloe vera is used to treat gastric ulceration, although no studies have yet investigated its efficacy in horses. To test the hypothesis that aloe vera would be noninferior to omeprazole in the treatment of equine gastric ulcer syndrome. Randomised, blinded clinical trial. Forty horses with grade ≥2 lesions of the squamous and/or glandular mucosa were randomly assigned to one of two groups. Horses received either aloe vera inner leaf gel (17.6 mg/kg bwt) b.i.d. or omeprazole (4 mg/kg bwt) s.i.d. for approximately 28 days, after which a repeat gastroscopic examination was performed to determine disease resolution. Horses with persistent lesions were offered a further 28 days of treatment with omeprazole (4 mg/kg bwt s.i.d.) and were re-examined on completion of treatment. Efficacy analyses were based on 39 horses that completed the trial. Equine squamous gastric disease (ESGD) was observed in 38 horses; improvement and healing rates in these horses were 56% and 17%, respectively, in the aloe vera group, and 85% and 75%, respectively, in the omeprazole group. Healing was less likely to occur in horses with prolonged gastric emptying. Equine glandular gastric disease (EGGD) was less common than ESGD (n = 14) and numbers were too small to perform meaningful statistical analyses. The hypothesis that aloe vera would be noninferior to omeprazole was not supported. No placebo control group was included. Limited numbers preclude any comment on the efficacy of aloe vera in the treatment of EGGD. Treatment with aloe vera was inferior to treatment with omeprazole. © 2017 EVJ Ltd.

    Serum pepsinogens I and II (PGI, PGII) levels were determined by PGI and PGII-RIA kits in 84 healthy controls and 128 patients of gastric diseases including 42 patients with gastric cancer. The results showed peptic ulcer cases had elevated PGI and PGII levels. The atrophic gastritis cases had low PGI levels and the gastric cancer cases had low PGI and low PGI/PGII ratio. Using the cut-off values of PGI<35 μg/L and PGI/PGII<1.5 for clinical purpose, the sensitivity and specificity of the test for gastric cancer was 73% and 78%, respectively. Combined with endoscope examination, the serum PGI and PGII levels are valuable for the early diagnosis of gastric cancer

    Mortality rates in complicated peptic ulcer disease are high. This study aimed to examine the prognostic importance of ulcer site in patients with peptic ulcer bleeding (PUB) and perforated peptic ulcer (PPU). a nationwide cohort study with prospective and consecutive data collection. all patients treated for PUB and PPU at Danish hospitals between 2003 and 2014. demographic and clinical data reported to the Danish Clinical Registry of Emergency Surgery. 90- and 30-d mortality and re-intervention. the crude and adjusted association between ulcer site (gastric and duodenal) and the outcome measures of interest were assessed by binary logistic regression analysis. Some 20,059 patients with PUB and 4273 patients with PPU were included; 90-d mortality was 15.3% for PUB and 29.8% for PPU; 30-d mortality was 10.2% and 24.7%, respectively. Duodenal bleeding ulcer, as compared to gastric ulcer (GU), was associated with a significantly increased risk of all-cause mortality within 90 and 30 d, and with re-intervention: adjusted odds ratio (OR) 1.47 (95% confidence interval 1.30-1.67); p ulcers (DUs) in PPU patients: adjusted OR 0.99 (0.84-1.16); p = 0.698, OR 0.93 (0.78 to 1.10); p = 0.409, and OR 0.97 (0.80-1.19); p = 0.799, respectively. DU site is a significant predictor of death and re-intervention in patients with PUB, as compared to GU site. This does not seem to be the case for patients with PPU.

    Peptic ulcer is one of the most common diseases affecting mankind. Although there are many products used for its treatment, most of these products produce severe adverse reactions requiring the search for novel compounds. Some Afromomum species are used traditionally to cure acute gastritis. To evaluate the antiulcer activity of the methanol extract of Aframomum pruinosum Gagnepain (Zingiberaceae) seeds against two major etiologic agents of peptic ulcer disease; Helicobacter pylori and non-steroidal anti-inflammatory drugs. The anti-Helicobacter activity of A. pruinosum was evaluated using the broth microdilution method. After oral administration of indomethacin (5 mg/kg) for 5 consecutive days, gastric ulcerated animals were divided into control group and five other groups: three groups that recieved respectively 125, 250 and 500 mg/kg of plant extract, the fourth group received Maalox (50 mg/kg) and the fifth group, Misoprostol (100 μg/kg), respectively, for 5 days. Ulcer areas, gastric mucus content and nitric oxide gastric levels of animals were assessed 24 h after this treatment. A. pruinosum extract shows a moderate anti-Helicobacter activity with an MIC value of 128 μg/mL. A. pruinosum extract, like Misoprostol and Maalox, markedly reduces the % of ulcerated area from 8.15 ± 0.33 to 1.71 ± 0.44% (500 mg/kg). It also increased significantly mucus and NO gastric production with respective values of 4.44 ± 1.35 and 965.81 ± 106.74 μmol/g (500 mg/kg). These findings suggest that A. pruinosum methanol extract possesses antiulcer properties as ascertained by the comparative decreases in ulcer areas, increase of mucus and NO gastric production.

    Bleeding per rectum is an uncommon presentation in pediatric patients. Heterotopic gastric mucosa in the rectum is a rare cause of rectal bleeding. Here, we report a 3-year-old child with a bleeding rectal ulcer that was initially diagnosed and managed as a solitary rectal ulcer syndrome. After 1 month, the patient persisted to have intermittent rectal bleed and severe anal pain. Repeat colonoscopy showed the worsening of the rectal ulcer in size. Pediatric surgeon excised the ulcer, and histopathological examination revealed a gastric fundic-type mucosa consistent with the diagnosis of gastric heterotopia of the rectum. Over the following 18 months, our patient had experienced no rectal bleeding and remained entirely asymptomatic. In conclusion, heterotopic gastric mucosa of the rectum should be considered in the differential diagnosis of a bleeding rectal ulcer.

    The effect of extirpation of the submandibular glands, an exocrine organ for epidermal growth factor/urogastrone (EGF/URO), and the effect of oral administration of synthetic human (EGF/URO) on healing of chronic gastric ulcers in rats has been investigated. Removal of the submandibular glands...... delayed healing of chronic gastric ulcers when examined after 50, 100, and 200 days. Oral administration of synthetic human EGF/URO stimulated gastric ulcer healing when examined after 25 and 50 days of treatment. The effect of synthetic human EGF/URO was comparable with that of cimetidine. The combined...... administration of synthetic human EGF/URO and cimetidine further increased healing of gastric ulcers compared with administration of each substance. Neither synthetic human EGF/URO, nor removal of the submandibular glands had any influence on gastric acid secretion. This study showed that the submandibular...

    To evaluate the usefulness of transabdominal ultrasonography as a screening examination in patients with suspicious gastric disease. We selected 141 patients with epigastric pain and who were found to have antral gastric wall thickening of more than 5 mm in transabdominal ultrasonography, and who underwent gastroscopy immediately following the ultrasonography examination, because we suspected that these patients had gastric disease. We measured the full thickness of the five layers of the gastric wall and evaluated the preservation of this five layered structure. We respectively compared the gastric wall thickness and the preservation of gastric layers in 26 normal, 91 gastritis, 12 gastric ulcer, and 12 gastric cancer patients, who were classified based on the gastroscopy results. The mean thicknesses of the gastric wall in the normal, gastritis, gastric ulcer and gastric cancer patients were 5.13±0.14 mm, 6.71±1.33 mm, 8.08±2.80 mm, and 12.45±3.70 mm, respectively. The gastric walls in the gastritis, gastric ulcer and gastric cancer patients were significantly thicker than that in the normal patients (p 0.01). Except for two patients with gastritis and three patients with gastric ulcer, the stratification of the gastric wall was preserved in all of the normal, gastritis and gastric ulcer patients, whereas it was disrupted in all of the patients with gastric cancer. Transabdominal ultrasonography in the fasting state may be a helpful and convenient modality, which can serve as a screening examination in the evaluation of gastric disease. Therefore, careful attention and effort are needed to evaluate the gastric wall during transabdominal ultrasonography

    Evidence indicates that a link between peptic ulcer disease (PUD) and selected psychosomatic factors may exist. A series of 70 consecutive male and female adult patients were categorized by peptic symptoms and divided into four groups: a) controls; b) gastric ulcer (GU); c) duodenal ulcer (DU); and d) chronic non-ulcer dyspepsia (CNUD). All patients were interviewed and asked to answer a questionnaire that included demographics, medical history and the incidence of negative life events. A decreased level of activity was a predominant finding in GU, DU and CNUD patients. Family history of PUD may be correlated with CNUD. Of interest was the finding that DU and CNUD patients presented a higher incidence of negative life events when compared to the other study groups. Negative life events that produce considerable stress may predispose to peptic symptoms in certain patients.

    Thymus algeriensis Boiss. et Reut. (Lamiaceae), popularly known as "mougecha" or "mazoukcha" is prolific in Mediterranean regions, mostly in North Africa, and is used in folk medicine to treat of stomach diseases. In this study, animals were induced with gastric ulcers using HCl/ethanol (0.3 M HCl/60% ethanol) and treated orally with essential oil of Thymus algeriensis (EOTa) in various doses ranging from 54 mg/kg body weight to 180 mg/kg body weight. The dose found to be effective was 180 mg/kg body weight, since this dose brought about a maximum reduction in lesion index in female rats. In gastric tissues, levels of total glutathiones (GSH, GST and GPx) and thiobarbituric acid reactive substances (TBARS) were evaluated. The activities of the antioxidant enzymes, catalase (CAT) and superoxide dismutase (SOD) were measured. Histopathological changes were observed using a cross section of gastric tissue. Chemical analysis revealed the presence of 13 components accounting for 77.7% of the essential oil from dried leaves. Oral administration of EOTa (54, 117 and 180 ml/kg) inhibited HCl/ethanol-induced ulcers. Lesion index was significantly reduced in ulcer induced animals treated with EOTa (HCl/ethanol + EOTa) compared to those ulcerated with HCl/ethanol but with no treatment given. Females showed a greater resistance to ulcers and gastric lesions occurred less often than in males. GSH, pH, enzymic antioxidants, and adherent mucus content were all significantly increased. From the data presented in this study, it can be concluded that male rats are more sensitive to gastric ulcers induced by HCl/ethanol than females.

    2018-01-01

    Full Text Available Radioembolization (RE is a selective internal radiation therapy (SIRT delivering targeted, high-dose, intra-arterial radiation directly to the vascular supply of liver tumors. Complications can occur due to aberrant deposition or migration of radiation microspheres into nontarget locations, including normal hepatic parenchyma, lungs, pancreas, and upper gastrointestinal (UGI tract. We report a case of gastric ulcers due to yttrium-90 (90Y seed migration to the stomach to alert clinicians to this rare cause of gastric injury. A 57-year-old woman with stage IV breast cancer with liver and lung metastases presented to the hospital with 2 months of worsening nausea and vomiting. Two months prior, she had received SIRT with 90Y microspheres without complications. Upper GI endoscopy showed diffuse gastritis and extensive antral ulceration. Biopsies revealed black, spherical foreign bodies, consistent with 90Y microspheres, documenting radiation injury. Radiation-induced UGI ulceration is caused by direct radiation injury from beta-radiation. Delay in diagnosis may be due to the nonspecificity of symptoms and temporal delay of symptom onset from SIRT, which was 2 months in our patient. Also, complaints may be attributed erroneously to adjuvant chemotherapy or widespread metastatic disease. Clinicians must consider radiation-associated toxicity in any SIRT-treated patient developing abdominal symptoms.

  10. Candida-associated gastric ulcer relapsing in a different position with a different appearance.

    Sasaki, Kenji

    2012-08-28

    An 87-year-old, Japanese woman was shown to have a submucosal tumor-like lesion with a deep, central ulceration covered with thick, whitish exudate in the stomach. Biopsy showed Candida tropicalis but not Helicobacter pylori (H. pylori). She had no predisposing factors or history of peptic ulcers nor had taken non-steroidal anti-inflammatory drugs (NSAIDs), diagnosed with Candida-associated gastric ulcer. Though cured of the lesion, she developed another ulcer in a different position, in which Candida was demonstrated but H. pylori was undetectable. This is the first case of recurrent Candida-associated gastric ulcer in the world. Detected in both the original and recurrent lesions in an H. pylori-negative patient with no antecedent ulcers who had not taken NSAIDs, Candida is considered, contrary to the prevailing opinion, to play an etiologic role in ulcer formation.

    Long-term administration of low-dose aspirin (LDA) is associated with a greater risk of adverse events, including gastroduodenal ulcers. The purpose of this study was to identify the risk factors for and assess the role of medication use in the development of peptic ulcer disease in Japanese patients with no history of peptic ulcers. Consecutive outpatients receiving LDA (75 mg/day) who underwent esophagogastroduodenoscopy between January and December 2010 were enrolled. Clinical parameters, peptic ulcer history, concomitant drugs, the presence of Helicobacter pylori infection, reason for endoscopy, and endoscopic findings were analysed. Of 226 total patients, 14 (6.2%) were endoscopically diagnosed with peptic ulcer. Age, sex, current smoking status, current alcohol consumption, endoscopic gastric mucosal atrophy, and abdominal symptoms were not significantly associated with peptic ulcers. Diabetes mellitus was more frequent (42.9% vs. 16.5%; P = 0.024) in patients with peptic ulcers than in those without peptic ulcers. Using multiple logistic regression analysis, co-treatment with anticoagulants or proton pump inhibitors (PPIs) was significantly associated with increased and decreased risk for peptic ulcer, respectively (odds ratio [OR], 5.88; 95% confidence interval [CI], 1.19 - 28.99; P = 0.03 and OR, 0.13; 95% CI, 0.02 - 0.73; P = 0.02, respectively). Co-treatment with additional antiplatelet agents, H2-receptor antagonists, angiotensin II Type 1 receptor blockers, angiotensin-converting enzyme inhibitor, 3-hydroxy-3-methylglutaryl-CoA reductase inhibitor, or nonsteroidal anti-inflammatory drugs was not associated with peptic ulcer development. The use of PPIs reduces the risk of developing gastric or duodenal ulcers in Japanese patients taking LDA without pre-existing gastroduodenal ulcers. However, this risk is significantly increased in both patients ingesting anticoagulants and patients with diabetes. These results may help identify

    Full Text Available Abstract Background The oral cavity is a rare but occasional target for metastases, which may masquerade as various benign and inflammatory lesions, and sometimes also be asymptomatic. Oral metastatic lesions have been described in various cancers, particularly lung, breast and kidney carcinoma. Case presentation We here describe an uncommon case of a hard palate mucosa and gingival metastasis from gastric carcinoma that was originally diagnosed as a periodontal disease. Histopathological examination of a biopsy of the lesion revealed a signet-ring cell carcinoma, and a subsequent biopsy of an ulcerated stomach lesion showed a poorly differentiated gastric carcinoma. The patient underwent gastric resection but died of heart failure on the tenth postoperative day; a post-mortem examination revealed a residual bilateral ovarian infiltration by gastric carcinoma (Krukenberg's tumor. Conclusion An occult carcinoma of the stomach may rarely metastasise to the oral cavity even as a first and exclusive manifestation; it is important to bear this possibility in mind because such conditions may mimic a benign disease.

    Peptic ulcer disease is represented by a lesion in the mucosa of the digestive tract due to imbalance of its aggressive and protective mechanisms. The main external factors of the development of peptic ulcers are Helicobacter pylori infection and the use of non-steroidal anti inflammatory drugs (NSAIDs) and acetylsalicylic acid (ASA). Symptoms of peptic ulcer disease are a common reason for visiting the family physician. All patients with symptoms of dyspepsia under the age of 50 and without the alarm symptoms should be tested whether H. pylori is present by performing the Urea Breath Test or stool antigene testing, and infection, if found, should be treated. Endoscopic examination is obligatory in patients older than 50 years and those with alarm symptoms. „Sequential therapy“ is recommended in Croatia as the first-line treatment of H. pylori infection, or triple therapy that comprises applying a proton pump inhibitor (PPI) in combination with amoxicillin and metronidazole. Four weeks after eradication therapy the control testing for H. pylori should be performed.

    To evaluate the effects of hydrotalcite combined with esomeprazole on gastric ulcer healing quality. Forty-eight patients diagnosed with gastric ulcer between June 2014 and February 2016 were randomly allocated to the combination therapy group or monotherapy group. The former received hydrotalcite combined with esomeprazole, and the latter received esomeprazole alone, for 8 wk. Twenty-four healthy volunteers were recruited and acted as the healthy control group. Endoscopic ulcer healing was observed using white light endoscopy and narrow band imaging magnifying endoscopy. The composition of collagen fibers, amount of collagen deposition, expression of factor VIII and TGF-β1, and hydroxyproline content were analyzed by Masson staining, immunohistochemistry, immunofluorescent imaging and ELISA. Following treatment, changes in the gastric microvascular network were statistically different between the combination therapy group and the monotherapy group ( P esomeprazole is superior to esomeprazole alone in improving gastric ulcer healing quality in terms of improving microvascular morphology, degree of structure maturity and function of regenerated mucosa.

    Full Text Available Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

    Gastric peptic ulcer is one of the common disorders of gastrointestinal tract, which occur due to an imbalance between the offensive and defensive factors. It is an illness that affects a considerable number of people worldwide. This study was conducted to evaluate the antiulcerogenic and antiulcer effects and recognize the basic mechanism of action of Piptadeniastrum africanum stem bark extracts. The aqueous and methanol extracts of Piptadeniastrum africanum were administered at the doses 125, 250 and 500 mg/kg to evaluate their effects on gastric ulcer induced by the HCl/ethanol mixture, indomethacin and acetic acid in Wistar strain male adult rats, aged between 12 and 16 weeks and weighing between 180 and 220 g. Ranitidine, Maalox and Misoprostol were used as standard drugs. Histopathological examination and nitric oxide level were performed to evaluate the basic mechanism of action of Piptadeniastrum africanum. Phytochemical screening was carried out to identify known phytochemicals present in these extracts. The aqueous and methanol extracts of stem bark of Piptadeniastrum africanum significantly inhibited (p ulceration induced by HCl/ethanol to the percentages of inhibition of 81.38; 98.75 and 100 % for the aqueous extract and then 75.83, 89.76 and 96.52 % for the methanol extract, and with the Indomethacin-induced ulcers, aqueous and methanol extracts of bark of Piptadeniastrum africanum reduce significantly (p cure 35.75; 52.33 and 98.58 % for the aqueous extract, and 33.7; 51.97; and 65.93 to the methanol extract. The results revealed a significant reduction of ulcerated surface in both extracts and increase of nitric oxide (NO) level with methanol extract. When compared to methanol extract, aqueous extract showed more pronounced effects, corresponding to percentages of healing of 59. 92; 84.12 and 59.65 % for the aqueous extract; and 70.43; 55.49 and 57.59 % for the methanol extract in the ulcer induced by acetic acid, all at the respective doses of

    The presence of ulcer in early gastric cancer (EGC) is important for the feasibility of endoscopic resection, only a few studies have examined the clinicopathological implications of endoscopic ulcer in EGC. To determine the role of endoscopic ulcer as a predictor of clinical behaviors in EGC. Data of 3,270 patients with EGC who underwent surgery between January 2005 and December 2012 were reviewed. Clinicopathological characteristics were analyzed in relation to the presence and stage of ulcer in EGC. Based on endoscopic findings, the stage of ulcer was categorized as active, healing, or scar. Logistic regression analysis was performed to analyze factors associated with lymph node metastasis (LNM). 2,343 (71.7%) patients had endoscopic findings of ulceration in EGC. Submucosal (SM) invasion, LNM, lymphovascular invasion (LVI), perineural invasion, and undifferentiated-type histology were significantly higher in ulcerative than non-ulcerative EGC. Comparison across different stages of ulcer revealed that SM invasion, LNM, and LVI were significantly associated with the active stage, and that these features exhibited significant stage-based differences, being most common at the active stage, and least common at the scar stage. The presence of endoscopic ulcer and active status of the ulcer were identified as independent risk factors for LNM. Ulcerative EGC detected by endoscopy exhibited more aggressive behaviors than non-ulcerative EGC. Additionally, the endoscopic stage of ulcer may predict the clinicopathological behaviors of EGC. Therefore, the appearance of ulcers should be carefully evaluated to determine an adequate treatment strategy for EGC.

    This study was conducted to assess the relationship between occurrence of gastric cancer and peptic ulcer, and the presence of H. pylori cagA gene and anti-CagA IgG, and to estimate the value of these antibodies in detecting infection by cagA gene-positive H. pylori strains in Saudi patients. The study included 180 patients who were subjected to upper gastrointestinal endoscopy in Taif province and Western region of Saudi Arabia (60 gastric cancer, 60 peptic ulcer, and 60 with non-ulcer dyspepsia). Gastric biopsy specimens were obtained and tested for H. pylori infection by rapid urease test and culture. PCR was performed on the isolated strains and biopsy specimens for detection of the cagA gene. Blood samples were collected and tested for CagA IgG by ELISA. H. pylori infection was detected among 72.8% of patients. The cagA gene and anti-CagA IgG were found in 63.4% and 61.8% of H. pylori-infected patients, respectively. They were significantly (p peptic ulcer compared with those with non-ulcer dyspepsia. Detection of the CagA IgG was 91.6% sensitive, 89.6% specific, and 90.8% accurate compared with detection of the cagA gene. Its positive and negative predictive values were 93.8% and 86%, respectively. The study showed a significant association between the presence of the cagA gene and gastric cancer and peptic ulcer disease, and between anti-CagA IgG and the cagA gene in Saudi patients. However, a further larger study is required to confirm this finding.

    Full Text Available The effects of fasting on peptic ulcer disease were evaluated in a prospective study, involving 23 fasting patients who underwent endoscopy before and after Ramadan. Eighteen patients took an H2-blocker (ranitidine, 150 mg twice daily regularly at “Suhur” and “Iftar” as prescribed, while 5 were drug defaulters. On the first endoscopy the diagnosis in 4 patients was active acute duodenal ulcer (AADU, in 8 patients was active chronic duodenal ulcer (ACDU in 8 patients was healed duodenal ulcer (HDU, in 2 patients was erosive duodenitis (ED, and in 1 patient was chronic gastric ulcer (CGU. All of the patients with AADU showed signs of healing on repeat endoscopy. None of the ACDU patients showed signs of healing on repeat endoscopy. Instead, 7 patients in this group bled during fasting. All of the 5 drug defaulters belonged to the ACDU group. One patient in the HDU group had developed an active ulcer near the previous scar, as which was seen on repeat endoscopy. The 2 patients with ED showed signs of healing, while the only patient with CGU had bled from the same ulcer as seen on repeat endoscopy. The results were compared with those of 15 nonfasting control subjects (6 patients with ACDU, 3 with HDU, and 6 with ED as diagnosed on the first endoscopy, who took an H2-blocker regularly. The repeat endoscopy did not show any change in these patients. In conclusion, we inferred that Ramadan fasting may prove hazardous in patients with peptic ulcer disease in general and with active chronic ulcers in particular, although the fact that only 23 patients volunteered for this study, of whom 5 were drug defaulters, is a limitation.

    Background This study aimed to evaluate the effects of the position of an acetic acid-induced gastric ulcer and the effects of prokinetic drugs on gastric emptying. Materials and Methods Male Sprague-Dawley rats were used in this study. Acetic acid ulcers were induced either in the region between the fundus and pylorus on the anterior wall of the stomach or in the glandular region on the greater curvature of the stomach to determine whether there were regional differences in the effect of the ulcers. Gastric emptying was evaluated with a breath test using [1- 13 C] acetic acid. In addition, the effects of the prokinetic drugs, metoclopramide and mosapride, on gastric emptying were also evaluated. Results Acetic acid induced ulcers in the region between the fundus and pylorus on the anterior wall of the stomach significantly delayed gastric emptying as compared with control rats, but not the acetic acid induced ulcers in the glandular region on the greater curvature of the stomach. Metoclopramide and mosapride did not improve the delayed gastric emptying even at doses that enhanced gastric emptying in normal rats. Conclusion These findings show that gastric emptying is influenced by the position of the ulcer and the region between the fundus and pylorus on the anterior wall plays an important role in gastric emptying. Moreover, it was found that metoclopramide and mosapride do not improve the delayed gastric emptying caused by acetic acid ulcers induced on the anterior wall in the region between the fundus and pylorus.

    Experiments performed with an inhibitor of diaminoxydase, aminoguanidine and an inhibitor of histidine decarboxylase, NSD 1055, showed that the frequency of gastric ulcers induced by promethazine was increased with the first inhibitor and decreased with the second. It is suggested that ulcers induced by promethazine in guinea pigs might be due to histamino-liberator effect of the antihistaminio compound.

    Full Text Available Background: Gastric ulcer includes benign mucosal and sub-mucosal lesions in the stomach wall. Gastrointestinal ulcers particularly stomach ulcer can be due to increased acid secretion. Objective: The aim of this study was to investigate the effect of aqueous extract of Satureja hortensis on gastric ulcer induced by acetic acid in rats. Methods: This experimental study was conducted on 60 female wistar rats weighing 200-250 g in the Biology Research Center of Zanjan, 2014. The rats were randomly divided into four groups (control, sham, 50mg/kg Satureja extract, and 80 mg/kg Satureja extract. Rats were operated after 24 hours fasting and gastric ulcers were induced by luminal application of 0.12 ml acetic acid solution (60%. On the first, fourth, seventh, tenth, and fourteenth days after oral administration of the Satureja hortensis extract, the stomach was excised (the rats related to any special day had received the extract separately and the ulcer size was measured. Data were analyzed using one-way ANOVA. Findings: Using the aqueous extract of Satureja hortensis resulted in significant ulcer healing in both intervention groups. Mean neutrophil, macrophage, and fibroblast count on the seventh, tenth and 14th day of intervention was significantly decreased in the intervention groups compared to the fourth day and compared to the control and sham groups. Conclusion: With regards to the results, it seems that the aqueous extract of Satureja hortensisis has significant healing effect on gastric ulcer induced by acetic acid.

    Escin, a natural mixture of triterpenoid saponin isolated from the seed of the horse chestnut, is reported to have a potent antiulcer activity against ethanol-induced gastric mucosal lesions. This study investigated the possible mechanisms underlying the gastroprotective effect of escin against indomethacin-induced gastric ulcer in mice. Gastric ulceration was induced by a single intragastric administration of indomethacin (18 mg/kg). The mice underwent intragastric treatment with escin at doses of 0.45, 0.9 or 1.8 mg/kg. Gastric lesion was estimated morphometrically and histopathologically 6 h after the indomethacin administration. The antioxidative parameters in gastric mucosa were measured. Moreover, the activity of myeloperoxidase and the contents of TNF-α, P-selectin and VCAM-1 in gastric tissues were determined. The results showed that escin protected gastric tissues against indomethacin-induced gastropathy as demonstrated from a reduction in the ulcer index and an attenuation of histopathologic changes. Escin caused significant reductions of the contents of malondialdehyde, TNF-α, P-selectin, VCAM-1 and myeloperoxidase activity. The altered activities of superoxide dismutase, catalase and glutathione peroxidase in the stomach tissues were also ameliorated by escin treatment. The present study demonstrated that escin had a protective effect against indomethacin-induced gastric ulcer in mice, not only by virtue of its antioxidant potential, but also due to its anti-inflammatory effect.

    Clausena excavata is a natural herb with both antioxidant and anti-inflammatory properties. It has been used for decades in folkloric practice for the amelioration of various ailments. In this study, the gastroprotective activity of methanolic extract of C. excavata leaves (MECE) was determined in the Sprague Dawley rat ethanol-induced gastric ulcer model. Rats were pretreated with a single dose of vehicle (5% Tween 20), 20 mg/mL omeprazole, 400 and 200 mg/mL of MECE dissolved in 5% Tween 20. Ulcer was induced with 5 mL/kg of ethanol and stomach tissue was obtained after 1 hour. Histological examination was done on hematoxylin and eosin, periodic acid-Schiff, and immunochemically stained gastric mucosal tissues. Prostaglandin E2, superoxide dismutase, catalase, glutathione peroxidase, and lipid peroxidation levels of the gastric tissue homogenates were also determined. Significantly (P<0.05) smaller ulcer areas, less intense edema, and fewer leukocytes’ infiltration were observed in MECE- and omeprazole-treated than in untreated gastric mucosa with ulcer. The gastric pH, mucus production, superoxide dismutase, catalase, and glutathione peroxidase contents increased, while the lipid peroxidation content decreased as a result of MECE treatment. Bcl-2-associated X protein was underexpressed, while heat shock protein 70 and transforming growth factor-beta protein were overexpressed in the ulcerated gastric mucosa tissues treated with omeprazole and MECE. Similarly, there was a reduction in the levels of tumor necrotic factor-alpha and interleukin-6, while the level of interleukin-10 was increased. This study showed that the gastroprotective effect of MECE is achieved through inhibition of gastric juice secretion and ulcer lesion development, stimulation of mucus secretion, elevation of gastric pH, reduction of reactive oxygen species production, inhibition of apoptosis in the gastric mucosa, and modulation of inflammatory cytokines.

    Although post-endoscopic submucosal dissection (ESD) iatrogenic ulcer is known to heal faster than peptic ulcer, some iatrogenic ulcers show delayed healing. The aim of this study was to clarify risk factors of delayed ulcer healing after gastric ESD. We retrospectively reviewed medical records of all patients who had ESD for gastric neoplasms (866 adenomas and 814 early gastric cancers) between January 2005 and February 2011. Of 1680 subjects, 95 had delayed ulcer healing in 3-month follow-up. Multivariate analysis showed that diabetes (OR 1.743; 95% CI 1.017-2.989, p = 0.043), coagulation abnormality (OR 3.195; 95% CI 1.535-6.650, p = 0.002), specimen size greater than 4 cm (OR 2.999; 95% CI 1.603-5.611, p = 0.001), and electrocoagulation (OR 7.149; 95% CI 1.738-29.411, p = 0.006) were revealed to be independent risk factors of delayed ulcer healing. Meanwhile, persistent Helicobacter pylori infection was not related to the delayed ulcer healing. Large iatrogenic ulcer by ESD with massive hemostasis, especially in patients with diabetes mellitus or coagulation abnormalities, tends to take more than 3 months to heal. For such cases, initial dosage increment of PPI or addition of other anti-ulcer agents after ESD may be beneficial.

    Objective: To find out the association of tobacco as a contributory factor in patients presenting with peptic ulcer disease (PUD). Results: Fifty-six percent of all the patients with PUD used tobacco, 33% as cigarette, 18% took it as 'naswar' and 5% of patients used it in both the forms. Of these, 85.7% (48/56) patients had duodenal ulcer and 14.3% (8/56) patients had gastric ulcer. All these patients were male none of the female patients used tobacco in any form. Moreover, 40% of PUD patients reported long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Conclusion: This study supports the view that use of tobacco is associated with PUD in men.

    Full Text Available Anti-angiogenic therapy with bevacizumab, an inhibitor of vascular endothelial growth factor, is commonly used in metastatic colorectal cancer and is rarely associated with gastrointestinal perforation, perforation being more frequent in the primary tumor site or at the anastomotic level. We present the case of a 64-year-old male with stage IV rectal adenocarcinoma who was on palliative chemotherapy with FOLFOX and bevacizumab. After the 4th chemotherapy cycle, our patient started fever and epigastric pain. He was hemodynamically stable, and signs of peritoneal irritation were absent. There were no alterations in the abdominal X-ray, and C-reactive protein was markedly elevated. A CT scan revealed a de novo thickness in the gastric antrum. Upper digestive endoscopy showed an ulcerated 40-mm lesion in the angulus, with a 20-mm orifice communicating with an exsudative cavity revested by the omentum. A conservative approach was decided including fasting, broad-spectrum intravenous antibiotics, and proton-pump inhibitors. Subsequent gastroduodenal series showed no contrast extravasation, allowing the resumption of oral nutrition. Esophagogastroduodenoscopy after 8 weeks showed perforation closure. Biopsies did not show neoplastic cells or Heliobacter pylori infection. Although the success in the conservative management of perforation allowing the maintenance of palliative chemotherapy (without bevacizumab, the patient died after 4 months due to liver failure. The reported case shows an uncommon endoscopic finding due to a rare complication of anti-angiogenic therapy. Additionally, it reminds clinicians that a history of gastroduodenal ulcers should be actively sought before starting anti-angiogenic treatment and that suspicion for perforation should be high in these cases.

    Full Text Available Transcatheter arterial radioembolization (TARE with Yttrium-90 (90Y-labeled microspheres has an emerging role in treatment of patients with unresectable hepatocellular carcinoma. Although complication of TARE can be minimized by aggressive pre-evaluation angiography and preventive coiling of aberrant vessels, radioembolization-induced gastroduodenal ulcer can be irreversible and can be life-threatening. Treatment of radioembolization-induced gastric ulcer is challenging because there is a few reported cases and no consensus for management. We report a case of severe gastric ulceration with bleeding that eventually required surgery due to aberrant deposition of microspheres after TARE.

    We studied 29 patients who had gastric secretion tests after a vagotomy for duodenal ulcer. There were 14 patients who developed a recurrent duodenal ulcer during the follow-up period and 15 patients who remained free from recurrence. Insulin-stimulated gastric secretion increased with time in the recurrent ulcer group, but not in the group with a satisfactory outcome. On the basis of our results, post-vagotomy patients could be divided into three groups. The first group had a high secretion ...

    Introduction: High morbidity rate, frequent relapses, and significant economic losses give reasons for highlighting the peptic ulcer disease as the most topical medical-statistical problem. The aim of the study is to assess the influence of the main risk factors on the course of gastric and duodenal peptic ulcer. Materials and methods: We formed up the risk groups consisted of patients with 12 modified (4) and regular (8) factors, each characterized with its own signs and gradations. We performed the quantitative evaluation of the factors and scored the signs thereof, the results of which were used for determination of the most informative ones. Results: Among the regular factors, we placed emphasis on gender, age, burdened heredity, and 0(I), Rh+ blood type. The risk of peptic ulcer in hereditary tainted young men of the working age with parental lineage (+2.3) and in males with 0(I) Rh+ blood type (+1.4) was proved. Helicobacter pylori (Hp) infection is a key contributor (a predictor of) to severity of the disease course (+9.7) among the modified risk factors. Negative effect of a concomitant pathology (+5.0), including hepatobiliary lesions (+3.8), hypertension (+4.0), and diabetes mellitus (+1.3) is also significant. Diet violation (+3.7), tobacco smoking (+3.2) and stress (+3.0) were ranked third. Conclusions: The results of quantitative evaluation of the factors scoring suggest of the underlying H.pylori infection (the significance of which is growing along with the growth of the disease incidence) and irrational diet as the most informatively important ones. We have established the direct dependence between the most important peptic ulcer risk factors, severity of the disease, and duration and periodicity of treatment thereof.

    Hyptis suaveolens is used by the traditional population in several parts of the world to treat inflammation, gastric ulcer and infection and is used as a crude drug to relieve symptoms related with gastric ulcer or gastritis in northeaster and central region of Brazil. the standardized ethanolic extract (Hs-EtOHE) and hexanic fraction (Hs-HexF) of Hyptis suaveolens (62,5, 125, 250 and 500 mg/kg) was evaluated in several models of acute gastric ulcers. The participation of NO was evaluated by pretreatment with L-NAME and non-protein sulfyhydryls by NEM in the gastroprotective effect. Hs-EtOHE and Hs-HexF markedly reduced the gastric lesions induced by all ulcerogenic agents (HCl/ethanol, ethanol, NSAIDs and hypothermic restraint-stress). Gastric ulcerations were exacerbated by administration of NEM suggesting that the gastroprotective mechanism of action of Hs-EtOHE and Hs-HexF involves sulfhydryl groups. Ours results show that an extract of Hyptis suaveolens, administered orally to rodents, present gastro protective activity in different models of acute of gastric ulcer and give some support to the reported claims on the use of this plant as a gastro protective agent. © 2013 Published by Elsevier Ireland Ltd.

It was revealed that for the first time revealed ulcers manifest a combination of abdominal pain and dyspepsia in 75% of cases. This is a defining pain, verifiable in 92% of newly diagnosed cases of ulcers of the stomach and duodenum. Symptoms proper dyspeptic disorders, represented mostly by two symptoms: nausea and feeling of heaviness in the epigastric region, are more common than morphological manifestations restructuring coolant in the examined patients.

    Whether it is a requirement to continue with anti-secretory therapy following anti-Helicobacter therapy in H. pylori positive gastric ulcers is an important question. As gastric ulcers tend to heal more slowly than duodenal ulcers, may be asymptomatic or only causing mild symptoms and success at curing H. pylori with current fist line therapies is 80% at best, clinicians will likely err on the side of caution and continue acid suppressive therapy to ensure healing of gastric ulcers. This is certainly recommended when dealing with bleeding ulcers.

    Full Text Available This study investigated the quantitative polyphenolic constituents and gastroprotective effects of aqueous leaf extracts of Spondias mombin and Ficus exasperata against indomethacin-induced gastric ulcer in rats. Ulceration was induced by a single oral administration of indomethacin (30 mg/kg body weight. Wistar rats were pretreated with esomeprazole (reference drug at a dose of 20 mg/kg body weight, S. mombin or F. exasperata at 100 and 200 mg/kg body weight once daily for 21 days prior to ulcer induction. At the end of the experiment, gastric secretions and antioxidant parameters were evaluated. We observed that the significantly increased (p < 0.05 ulcer index, gastric volume, malondialdehyde level and pepsin activity were effectively reduced following treatment with S. mombin and F. exasperata. The extracts also markedly attenuated the reduced activity of superoxide dismutase as well as pH and mucin content in the ulcerated rats. These findings are indicative of gastroprotective and antioxidative potentials of the extracts which is also evident in the degree of % inhibition against ulceration. The available data in this study suggest that the extracts of S. mombin and F. exasperata proved to be capable of ameliorating indomethacin-induced gastric ulceration and the probable mechanisms are via antioxidative and proton pump inhibition.

    Background. Helicobacter pylori (HP) infection and nonsteroidal anti-inflammatory drugs (NSAID) use are considered the main risk to develop peptic ulcer disease (PUD). However, PUD also occurs in the absence of HP infection and/or NSAID use. Recently, we have found evidence that Epstein-Barr virus (EBV) reactivation increases the risk to develop premalignant and malignant gastric lesions. Objective. To study a possible association between EBV and PUD. Methods. Antibodies against an EBV reactivation antigen, HP, and the HP virulence factor CagA were measured in sera from 207 Mexican subjects, controls (healthy individuals, n = 129), and PUD patients (n = 78, 58 duodenal and 20 gastric ulcers). Statistical associations were estimated. Results. Duodenal PUD was significantly associated with high anti-EBV IgG titers (p = 0.022, OR = 2.5), while anti-EBV IgA was positively associated with gastric PUD (p = 0.002, OR = 10.1). Conclusions. Our study suggests that EBV reactivation in gastric and duodenal epithelium increases the risk to develop PUD.

    Peptic ulcer disease is a significant cause of morbidity and mortality worldwide, with a significant burden in low- and middle-income countries. However, there is limited information regarding management of peptic ulcer disease in these countries. This study describes surgical interventions for peptic ulcer disease in sub-Saharan Africa. A systematic review was performed using PubMed, EMBASE, and African Index Medicus for studies describing surgical management of peptic ulcer disease in sub-Saharan Africa. From 55 published reports, 6594 patients underwent surgery for peptic ulcer disease. Most ulcers (86%) were duodenal with the remainder gastric (14%). Thirty-five percent of operations were performed for perforation, 7% for bleeding, 30% for obstruction, and 28% for chronic disease. Common operations included vagotomy (60%) and primary repair (31%). The overall case fatality rate for peptic ulcer disease was 5.7% and varied with indication for operation: 13.6% for perforation, 11.5% for bleeding, 0.5% for obstruction, and 0.3% for chronic disease. Peptic ulcer disease remains a significant indication for surgery in sub-Saharan Africa. Recognizing the continued role of surgery for peptic ulcer disease in sub-Saharan Africa is important for strengthening surgical training programs and optimizing allocation of resources.

    Perforated peptic ulcer (PPU) is a common surgical emergency and treatment involves omental patch repair (PR). Gastric resection (GR) is reserved for difficult pathologies. We audit the outcomes of GR at our institution and evaluate the pre-operative factors predicting the need for GR. This is a single-institution, retrospective study of patients with PPU who underwent surgery from 2004 to 2012. Demographics, clinical presentation and intra-operative findings were studied to identify factors predicting the need for GR in PPU. An audit of clinical outcomes and mortality for all patients with GR is reported. 537 (89.6 %) patients underwent PR and 62 (10.4 %) patients GR. Old age (p peptic ulcer disease (PUD) (p = 0.0159), low hemoglobin (p ulcer size (p < 0.0001) predict the need for GR. On multivariate analysis only low serum albumin (OR 5.57, 95 % CI 1.56-19.84, p = 0.008) predicted the need for GR. The presence of Helicobacter pylori infection was protective against GR (OR 0.25, 95 %CI 0.14-0.44, p < 0.0001). Morbidity and mortality of GR was 27.7 and 24.2 %, respectively. GR is needed in one in ten cases of PPU. Low serum albumin predicted the need for GR on multivariate analysis. Morbidity and mortality of GR remains high.

  3. Diosmin protects against ethanol-induced gastric injury in rats: novel anti-ulcer actions.

    Directory of Open Access Journals (Sweden)

    Hany H Arab

    Full Text Available Alcohol consumption has been commonly associated with gastric mucosal lesions including gastric ulcer. Diosmin (DIO is a natural citrus flavone with remarkable antioxidant and anti-inflammatory features that underlay its protection against cardiac, hepatic and renal injuries. However, its impact on gastric ulcer has not yet been elucidated. Thus, the current study aimed to investigate the potential protective effects of DIO against ethanol-induced gastric injury in rats. Pretreatment with DIO (100 mg/kg p.o. attenuated the severity of ethanol gastric mucosal damage as evidenced by lowering of ulcer index (UI scores, area of gastric lesions, histopathologic aberrations and leukocyte invasion. These actions were analogous to those exerted by the reference antiulcer sucralfate. DIO suppressed gastric inflammation by curbing of myeloperoxidase (MPO and tumor necrosis factor-α (TNF-α levels along with nuclear factor kappa B (NF-κB p65 expression. It also augmented the anti-inflammatory interleukin-10 (IL-10 levels. Meanwhile, DIO halted gastric oxidative stress via inhibition of lipid peroxides with concomitant enhancement of glutathione (GSH, glutathione peroxidase (GPx and the total antioxidant capacity (TAC. With respect to gastric mucosal apoptosis, DIO suppressed caspase-3 activity and cytochrome C (Cyt C with enhancement of the anti-apoptotic B cell lymphoma-2 (Bcl-2 in favor of cell survival. These favorable actions were associated with upregulation of the gastric cytoprotective prostaglandin E2 (PGE2 and nitric oxide (NO. Together, these findings accentuate the gastroprotective actions of DIO in ethanol gastric injury which were mediated via concerted multi-pronged actions, including suppression of gastric inflammation, oxidative stress and apoptosis besides boosting of the antioxidant and the cytoprotective defenses.

    A 66 year-old obese woman with arthrosis, self-medicated with oral nimesulide, 200 mg daily. After 6 weeks she developed nausea, jaundice and dark urine. Two weeks later she had recurrent hematemesis and was hospitalized. Besides obesity and anemia her physical examination was unremarkable. An upper GI endoscopy revealed 3 acute gastric ulcers and a 4th one in the pyloric channel. Abdominal ultrasonogram showed a slightly enlarged liver with diffuse reduction in ecogenicity; the gallbladder and biliary tract were normal. Blood tests demonstrated a conjugated hyperbilirubinemia (maximal total value: 18.4 mg/dl), ALAT 960 U/l, ASAT 850 U/l, GGT 420 U/l, alkaline phosphatases mildly elevated, pro-time 49% and albumin 2.7 mg/dl. Serum markers for hepatitis A, B and C viruses were negative. ANA, AMA, anti-SmA, were negative. Ceruloplasmin was normal. A liver biopsy showed bridging necrosis and other signs of acute toxic liver damage. Gastric ulcers healed after conventional treatment and hepatitis subsided after 2 months leaving no signs of chronic liver damage. The diagnosis of toxic hepatitis due to nimesulide was supported by the time-course of drug usage, sex, age, absence of other causes of liver disease, a compatible liver biopsy and the improvement after drug withdrawal. Peptic ulcers or toxic hepatitis have been previously described as independent adverse reactions in patients taking nimesulide or other NSAIDs but their simultaneous occurrence in a single patient is a unique event that deserves to be reported.

    Solcoseryl, a deproteinized extract of calf blood, protects the gastric mucosa against various topical irritants and enhances the healing of chronic gastric ulcerations but the mechanisms of these effects have been little studied. This study was designed to elucidate the active principle in Solcoseryl and to determine the role of prostaglandins (PG) and polyamines in the antiulcer properties of this agent. Using both, the radioimmunoassay and radioreceptor assay, EGF-like material was detected in Solcoseryl preparation. Solcoseryl given s.c. prevented the formation of stress-induced gastric lesions and this was accompanied by an increase in the generation of PGE2 in the gastric mucosa. Similar effects were obtained with EGF. Pretreatment with indomethacin, to suppress mucosal generation of prostaglandins (PG), greatly augmented stress-induced gastric ulcerations and antagonized the protection exerted by both Solcoseryl and EGF. Solcoseryl, like EGF, enhanced the healing of chronic gastro-duodenal ulcerations. This effect was abolished by the pretreatment with difluoromethylornithine, an inhibitor of ornithine decarboxylase, the key enzyme in the biosynthesis of polyamines. The healing effects of Solcoseryl and EGF was also reduced by prednisolone which decreased the angiogenesis in the granulation tissue in the ulcer area. These results indicate that Solcoseryl 1. contains EGF-like material, 2. displays the protective and ulcer healing effects similar to those of EGF and involving both PG and polyamines and 3. acts via similar mechanism as does EGF.

    Full Text Available In the present study, the ethanolic root extract of Desmodium gangeticum (L. DC., Fabaceae, (EDG, have been studied in various acute and chronic ulcer mouse models. Oral administration of root extract, significantly decrease the ulcer index and lesion number in a dose dependent manner against ethanol induced acute gastric ulcer in mice. In gastric ulcerated animal that received high dose of 150 mg/kg EDG, the mucosa showed no ulceration with slight focal congestion and the glands appeared normal. Pylorus ligated mice, pretreated with EDG showed significant decrease in ulcerous activity under chronic condition. The highest dose (150 mg/kg of the extract provoked a marked increase in protein and glutathione levels, when compare to control. Furthermore, gastric juice, free acidity and total acid output were inhibited in a dose-dependent manner at p<0.05 level. Our results indicate that the EDG possess gastroprotective activity and increasing regeneration of damaged gastric mucosa and thus safe for human use.

    To elucidate the characteristics of hemorrhagic gastric/duodenal ulcers in a post-earthquake period within one medical district. Hemorrhagic gastric/duodenal ulcers in the Iwate Prefectural Kamaishi Hospital during the 6-mo period after the Great East Japan Earthquake Disaster were reviewed retrospectively. The subjects were 27 patients who visited our hospital with a chief complaint of hematemesis or hemorrhagic stool and were diagnosed as having hemorrhagic gastric/duodenal ulcers by upper gastrointestinal endoscopy during a 6-mo period starting on March 11, 2011. This period was divided into two phases: the acute stress phase, comprising the first month after the earthquake disaster, and the chronic stress phase, from the second through the sixth month. The following items were analyzed according to these phases: age, sex, sites and number of ulcers, peptic ulcer history, status of Helicobacter pylori (H. pylori) infection, intake of non-steroidal anti-inflammatory drugs, and degree of impact of the earthquake disaster. In the acute stress phase from 10 d to 1 mo after the disaster, the number of patients increased rapidly, with a nearly equal male-to-female ratio, and the rate of multiple ulcers was significantly higher than in the previous year (88.9% vs 25%, P stress phase starting 1 mo after the earthquake disaster, the number of patients decreased to a level similar to that of the previous year. There were more male patients during this period, and many patients tended to have a solitary ulcer. All patients with duodenal ulcers found in the acute stress phase were negative for serum H. pylori antibodies, and this was significantly different from the previous year's positive rate of 75% (P stress caused by an earthquake disaster may have affected the characteristics of hemorrhagic gastric/duodenal ulcers.

    The gastric pathogen Helicobacter pylori utilizes molecular hydrogen (H2) as a respiratory substrate during colonization in the gastric mucosa. However, the link between molecular H2 and the pathogenesis of peptic-ulcer disease (PUD) and non-ulcerous dyspepsia (NUD) by the enzymatic activity of H. pylori still remains mostly unknown. Here we provide evidence that breath H2 excretion profiles are distinctly altered by the enzymatic activity of H. pylori for individuals with NUD and PUD. We subsequently unravelled the potential molecular mechanisms responsible for the alteration of H2 in exhaled breath in association with peptic ulcers, encompassing both gastric and duodenal ulcers, along with NUD. We also established that carbon-isotopic fractionations in the acid-mediated bacterial environment regulated by bacterial urease activity cannot discriminate the actual disease state i.e. whether it is peptic ulcer or NUD. However, our findings illuminate the unusual molecular H2 in breath that can track the precise evolution of PUD and NUD, even after the eradication of H. pylori infection. This deepens our understanding of the pathophysiology of PUD and NUD, reveals non-invasively the actual disease state in real-time and thus offers a novel and robust new-generation strategy for treating peptic-ulcer disease together with non-ulcer related complications even when the existing (13)C-urea breath test ((13)C-UBT) fails to diagnose.

    2016-12-01

    Full Text Available Primary gastrointestinal (GI lymphoma is a heterogeneous disease with varied clinical presentations. The stomach is the most common GI site and accounts for 70% to 75% of GI lymphomas. We present a patient with gastric diffuse large B cell lymphoma (DLBCL who presented with significant weight loss, early satiety, and multifocal ulcerated gastric lesions. Esophagoduodenoscopy should be performed in patients presenting with warning symptoms as in our case. Diagnosis is usually made by endoscopic biopsies. Multiple treatment modalities including surgery, radiotherapy, and chemotherapy have been used. Advancements in endoscopic and pathologic technology decrease turnaround time for diagnosis and treatment initiation, thus reducing the need for surgery. Health care providers should maintain a high level of suspicion and consider gastric DLBCL as part of the differential diagnosis, especially in those with warning symptoms such as weight loss and early satiety with abnormal endoscopic findings.

    We aimed at determining peptic ulcer disease (PUD) incidence among chronic kidney disease (CKD) patients during 1998-2008, compared to patients without CKD, and at examining associations between CKD and PUD. Data for 1998-2008 were extracted from the National Health Insurance Research Database in Taiwan. The annual PUD incidence (cases per thousand persons per year) was calculated separately for patients with and without CKD. Characteristics of patients with newly diagnosed PUD (n = 16322) were compared to those of a control group without PUD (n = 32644). The 2 groups were matched for age, sex, and index year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Over the 10-year period, the PUD incidence was ∼10-12 times higher in CKD patients than in those without CKD. Its incidence in elderly CKD patients increased rapidly over time. For CKD patients, most PUD events (>95%) were managed during hospitalization. Peptic ulcer risk, adjusted for all potential confounders, was much higher in CKD patients undergoing hemodialysis (adjusted OR, 9.74; 95% CI, 7.11-13.31). Maintenance hemodialysis patients were 2 times more likely to have gastric ulcers than duodenal ulcers, while CKD patients not on dialysis had similar risks for both. There were no significant interactions between medications and CKD status on the peptic ulcer risk. Unlike CKD patients on nonsteroidal anti-inflammatory drugs and clopidogrel, those on aspirin did not have a higher peptic ulcer risk (adjusted OR, 0.88; 95% CI, 0.44-1.77). CKD patients have a substantially increased PUD risk, and the majority of CKD patients with PUD require hospital management. Further, peptic ulcer risk is affected by hemodialysis therapy, patient status (inpatient vs. outpatient), and ulcerogenic medications.

    Full Text Available The presence of ulcer in early gastric cancer (EGC is important for the feasibility of endoscopic resection, only a few studies have examined the clinicopathological implications of endoscopic ulcer in EGC.To determine the role of endoscopic ulcer as a predictor of clinical behaviors in EGC.Data of 3,270 patients with EGC who underwent surgery between January 2005 and December 2012 were reviewed. Clinicopathological characteristics were analyzed in relation to the presence and stage of ulcer in EGC. Based on endoscopic findings, the stage of ulcer was categorized as active, healing, or scar. Logistic regression analysis was performed to analyze factors associated with lymph node metastasis (LNM.2,343 (71.7% patients had endoscopic findings of ulceration in EGC. Submucosal (SM invasion, LNM, lymphovascular invasion (LVI, perineural invasion, and undifferentiated-type histology were significantly higher in ulcerative than non-ulcerative EGC. Comparison across different stages of ulcer revealed that SM invasion, LNM, and LVI were significantly associated with the active stage, and that these features exhibited significant stage-based differences, being most common at the active stage, and least common at the scar stage. The presence of endoscopic ulcer and active status of the ulcer were identified as independent risk factors for LNM.Ulcerative EGC detected by endoscopy exhibited more aggressive behaviors than non-ulcerative EGC. Additionally, the endoscopic stage of ulcer may predict the clinicopathological behaviors of EGC. Therefore, the appearance of ulcers should be carefully evaluated to determine an adequate treatment strategy for EGC.

    Despite availability of effective therapies, peptic ulcer disease (PUD) remains a major global disease, resulting from a combination of persistent Helicobacter pylori infection and widespread use of nonsteroidal anti-inflammatory drugs. Albeit endoscopy definitely represents the mainstay diagnostic technique, patients presenting to emergency departments with unexplained abdominal pain generally undergo multidetector CT as an initial investigation. Although superficial ulcers generally remain inconspicuous, careful multiplanar CT interpretation may allow to detect deep ulcers, secondary mural and extraluminal signs of peptic gastroduodenitis, thereby allowing timely endoscopic verification and appropriate treatment. This pictorial essay aims to provide radiologists with an increased familiarity with CT diagnosis of non-perforated PUD, with emphasis on differential diagnosis. Following an overview of current disease epidemiology and complications, it explains the appropriate CT acquisition and interpretation techniques, and reviews with several examples the cross-sectional findings of uncomplicated PUD. Afterwards, the CT features of PUD complications such as ulcer haemorrhage, gastric outlet obstruction, biliary and pancreatic fistulisation are presented. • Gastric and duodenal peptic ulcers are increasingly caused by nonsteroidal anti-inflammatory drugs • Multiplanar CT interpretation allows detecting deep ulcers and secondary signs of gastroduodenitis • CT diagnosis of uncomplicated peptic disease relies on direct and indirect signs • Currently the commonest complication, haemorrhage may be treated with transarterial embolisation • Other uncommon complications include gastric outlet obstruction and biliopancreatic fistulisation.

    Effects of the flavonoid rich fraction of the stem bark of Manilkara hexandra (Roxb.) Dubard, have been studied on ethanol, ethanol-indomethacin and pylorus ligated gastric ulcers in experimental animals. Oral administration of the ethyl acetate extract (extract A3) inhibited the formation of gastric lesions induced by ethanol in a dose dependent manner. The protective effect of extract A3 against ethanol induced gastric lesions was not abolished by pretreatment with indomethacin (10 mg kg(-1)). Further, extract A3 inhibited increase in vascular permeability due to ethanol administration. Extent of lipid peroxidation was significantly reduced in animals treated with extract. Extract A3 also inhibited the formation of gastric ulcers induced by pylorus ligation, when administered both orally and intraperitoneally. Moreover, pretreatment with extract A3 increased mucus production and glycoprotein content, which was evident from the rise in mucin activity and TC: PR ratio. Copyright 2004 John Wiley & Sons, Ltd.

    The elderly population has experienced increased life expectancy as well as the increased incidence of gastric ulcers. The peels of fruits from Citrus aurantium L., popularly known in Brazil as orange bitter, are commonly used asatea form for the treatment of gastrointestinal tract disorders, such as ulcer and gastritis. We evaluated the healing effects of essential oil from the peels of Citrus aurantium fruits (OEC) on gastric ulcers in middle-aged rats. We examined the effects of a 14-day chronic OEC treatment on gastric mucosa in middle-aged male Wistar rats that were given acetic-acid-induced gastric lesions by morphometric and immunohistological analyses. Oral OEC treatment significantly reduced the lesion area (76%) within the gastric mucosa and significantly increased (P Citrus aurantium effectively heals gastric ulcers in middle-aged animals; however, safe use of OEC demands special care and precautions.

    Mallory-Weiss tears (MWTs) rarely require surgical intervention. A 60-year-old female presented with massive hematemesis secondary to MWT and gastric ulceration. After failure of endoscopic management, an operative approach was embarked on, with a direct surgical hemostasis of the Mallory-Weiss tear and exclusion of the gastric ulcer. This exclusion strategy may be applicable for other patients with uncontrolled upper gastrointestinal bleeding in whom a simple repair would be difficult.

    The purpose of this study was to investigate the effect of astaxanthin extracted from Paracoccus carotinifaciens on gastric mucosal damage in murine gastric ulcer models. Mice were pretreated with astaxanthin for 1 h before ulcer induction. Gastric ulcers were induced in mice by oral administration of hydrochloride (HCl)/ethanol or acidified aspirin. The effect of astaxanthin on lipid peroxidation in murine stomach homogenates was also evaluated by measuring the level of thiobarbituric acid reactive substance (TBARS). The free radical scavenging activities of astaxanthin were also measured by electron spin resonance (ESR) measurements. Astaxanthin significantly decreased the extent of HCl/ethanol- and acidified aspirin-induced gastric ulcers. Astaxanthin also decreased the level of TBARS. The ESR measurement showed that astaxanthin had radical scavenging activities against the 1,1-diphenyl-2-picrylhydrazyl radical and the superoxide anion radical. These results suggest that astaxanthin has antioxidant properties and exerts a protective effect against ulcer formation in murine models. Copyright © 2011 John Wiley & Sons, Ltd.

    The incidence of peptic ulcer-induced gastric outlet obstruction is constantly declining. The aim of this study was to present our results in the treatment of gastric outlet obstruction with highly selective vagotomy and gastrojejunostomy. This retrospective clinical study included 13 patients with peptic ulcer-induced gastric outlet obstruction operated with higly selective vagotomy and gastrojejunostomy. A 3-year follow-up was conducted including clinical interview and upper gastrointestinal endoscopy on 1 and 3 years after the surgery. The most common preoperative symptom was vomiting (in 92.3% of patients). The mean preoperative body mass index was 16.3 +/- 3.1 kg/m2, with 9 patients classified preoperatively as underweight. There were no intraoperative complications, nor mortality. At a 3-year follow-up there was no ulcer recurrence. Delayed gastric emptying was present in 1, bile reflux in 2, and erosive gastritis in 1 patient. Two patients suffered from mild "dumping" syndrome. Higly selective vagotomy combined with gastrojejunostomy is a safe and easily feasible surgical solution of gastric outlet obstruction induced by peptic ulcer. Good functional results and low rate of complications can be expected at a long-term follow-up.

    We investigated the volume of dyspeptic patients referred by general practitioners (GPs) to upper gastrointestinal endoscopy and the impact on endoscopic findings. We also examined the correlation between clinical symptoms and endoscopic findings. We collected data on patients sent for upper gastrointestinal endoscopy by GPs of 30 healthcare centres in 1996 in our hospital referral area of 260,000 inhabitants. In addition, national and local cancer registries were used to enumerate the gastric cancer cases detected in 1996. The study population consisted of 3378 patients, mean age 58 years (interquartile range 25 years, male:female 1:1.3). Among the 30 healthcare centres, referral volumes for upper gastrointestinal endoscopy varied from 0.6 to 9.2 per 1000 inhabitants per year (median 3.3/1000/year). In healthcare units with 'high' (> or = 3.3/1000/year, 15 healthcare units, 1297 patients) and 'low' (detection rates were as follows: duodenal ulcer (DU) 3.5% (n = 46) versus 4.0% (n = 83, P = 0.5), gastric ulcer (GU) 4.9% (n = 64) versus 5.3% (n = 110, P = 0.6), gastropathy 43.8% (n = 568) versus 35.6% (n = 736, P peptic ulcers or gastric cancer. Alarm symptoms associate strongly with significant gastric lesions such as GU and cancer.

    Full Text Available Current treatment guidelines for acid-related diseases (ARDs recommend first-line treatment with a proton pump inhibitor (PPI to reduce gastric acid production. PPIs are indicated in the management of gastroesophageal reflux disease (reflux esophagitis, nonerosive reflux disease, peptic ulcer (gastric and duodenal ulcer, non-steroidal anti-inflammatory drug (NSAID-associated ulcer, bleeding ulcer, functional dyspepsia, and in association with Helicobacter pylori eradication therapy when needed. Currently, PPIs (omeprazole, lansoprazole, pantoprazole, rabeprazole and esomeprazole are widely used for the treatment of ARDs. All 5 PPIs are effective. However, there are differences in PPI pharmacokinetic and pharmacodynamic profiles that might influence their clinical utility. Rabeprazole is a useful option for the treatment of acid-related diseases due to its rapid onset of acid inhibition and few drug interactions.

    Full Text Available Background: Some morbidly obese patients do not qualify for bariatric surgery due to general health contraindications. Intragastric balloon treatment might be a therapeutic option in the above-mentioned cases. It can prime super-obese patients with end-stage disease for bariatric surgery. As a neoadjuvant therapy before surgery, it leads to a downstage of the disease by preliminary weight reduction, to an improvement in general health and, in summary, to a reduction of the perioperative risk. It is generally considered to be a safe method. However, due to the wide range of possible complications and unusual symptoms after intragastric balloon treatment, an interdisciplinary, instead of only a surgical or endoscopic, treatment and follow-up might be recommended in these patients. Case Report: We here describe a potential life-threatening complication in the form of gastric bleeding as a consequence of intragastric balloon treatment and simultaneous aspirin taking and Helicobacter pylori infection. Conclusion: There have been reports of some complications of intragastric balloon treatment. However, to the best of our knowledge there were no reports concerning life-threatening hemorrhage from gastric ulcer.

    2000-02-01

    The eradication of Helicobacter pylori (H. pylori) infection has led to a dramatic benefit for patients with gastroduodenal ulcer disease, as the majority of these patients receive a lifelong cure. Relapses after successful H. pylori cure may be caused by either recrudescence or reinfection, both rare events nowadays, or be attributed to non-steroidal anti-inflammatory drugs or aspirin intake. In certain geographical areas, H. pylori-negative relapses are proposed as a new, pathophysiological and not yet elucidated entity. The cure of H. pylori infection in uncomplicated duodenal ulcer diseases consists of 7 days of proton pump inhibitor (PPI) based triple therapy, containing two antibiotics from clarithromycin, amoxicillin and metronidazole. In gastric ulcer, it is recommended that the PPI is continued for a further 3 weeks as these ulcers have a prolonged healing time. Rescue therapies after failure need to take into consideration the resistance pattern of the micro-organism and are offered in the form of quadruple therapy or a high-dose PPI with amoxicillin.

    Keratolysis is a rare severe complication following systemic autoimmunologic diseases. Despite of complex therapeutic treatments, the prognosis is very poor. Ten eyes from seven patients with corneal ulcers were reported (age 45 - 73 years, mean 63 years; 6 women, 1 man). The corneal ulcer was perforated in 7 eyes. Five patients suffered from rheumatoid arthritis, and one patient developed a Sjögren's syndrome. Besides, one patient had shown both autoimmunologic diseases. After clinical attendance, visual acuity in the eyes with nonperforated ulcers was between 0.1 and 0.4, and in the eyes with perforated ulcers between light perception and 0.2. In 7 eyes with perforated corneal ulcers an emergency tectonic conjunctival plasty and, 1 - 2 days later, a keratoplasty had been performed. Postoperatively, local therapies had been initiated with antibiotic and immunosuppressive eyedrops as well as with conventional drops for dry-eye symptoms. Because of the autoimmunologic diseases of the patients, a systemic immunosuppressive therapy had been arranged. Follow-up period had been between 4 weeks and 3,5 years (mean 16 months). In the three eyes with nonperforated ulcers which received an antibiotic and immunosuppressive treatment, visual acuity was found at 1 / 20 and 0.4. However, in spite of stabilized findings in the 5 eyes with perforated ulcers, the visual acuity was in this case only between light perception and 0.05. One patient with a perforated ulcer and one patient with a recurrent corneal perforation after keratoplasty refused further operative procedures. Finally, both eyes had to undergo evisceration. Despite of intensive local and systemic immunosuppressive as well as operative therapies, corneal ulcers associated with autoimmunologic diseases (rheumatoid arthritis, Sjögren's syndrome) may cause a marked decrease of visual acuity or the loss of an eye. With regard to the healthy eye, an immunosuppressive therapy for life is most important.

  15. Pharmacotherapy of Peptic Ulcer Disease

    Full Text Available The etiology of peptic ulcer is multifactorial; except for omeprazole, all drugs used for the treatment of peptic ulcer result in healing with no statistical difference at four weeks. The healing rare increases with time for active medication and placebo, and is lower among smokers than nonsmokers for all drugs but misoprostol. Mucosal protectives (or ‘cytoprotectives’ as a group seem to have a lower relapse rate than the H2 receptor antagonists at one year. Combination therapy has not yet proved to be better than single drug therapy; however, the number of studies is still small, and more clinical trials are necessary. Resistant ulcers have demonstrated that acid is one of several etiological factors and that more research is needed to elucidate the reason(s for refractoriness. The choice of therapeutic agent is generally made according to patient compliance, medication cost, side effects, effectiveness, relapse rate and physician experience with the drug. Long term maintenance therapy is effective in the prevention of ulcer relapse and is especially recommended for selected patient groups, including patients with recurrent or bleeding ulcer, patients with concomitant nonsteroidal anti-inflammatory drug use, and elderly women. Omeprazole is the treatment of choice for moderate to severe esophagitis and should be reserved for large and resistant ulcers.

    A method producing persistent gastric ulcers in the rhesus monkey by combined mucosal injury and γ-irradiation was modified and evaluated in the rabbit. γ-Irradiation (800-1000 cGy) immediately after removal of 2-mm-diameter sections of antral mucosa resulted in ulcer craters 5-7 days later. Ulcer sites were characterized by loss of the mucosa, muscularis mucosa, and much of the submucosa. The exposed submucosa was coated with fibrin and necrotic debris infiltrated with heterophils, the rabbit equivalent of neutrophils. These ulcers strongly resemble human chronic gastric ulcers. Binding of Carafate (sucralfate; Marion Laboratories, Inc., Kansas City, MO) and Maalox (magnesia-alumina oral suspension; Wm. H. Rorer, Inc., Ft. Washington, PA) to ulcer and nearby nonulcer sites in the antrum was assessed 1 hour after drug dosing. Drug binding was determined by aluminum quantitation of stomach wall punch biopsies at necropsy. Both drugs significantly increased aluminum bound to the stomach wall compared with vehicle treatment. Significantly more antiulcer drug was bound to ulcer sites than to nearby nonulcer sites only after sucralfate administration. This model of persistent gastric ulcer should be useful to further study gastric ulcer pathogenesis and treatment

It has been used for decades in folkloric practice for the amelioration of various ailments. In this study, the gastroprotective activity of methanolic extract of C. excavata leaves (MECE was determined in the Sprague Dawley rat ethanol-induced gastric ulcer model. Rats were pretreated with a single dose of vehicle (5% Tween 20, 20 mg/mL omeprazole, 400 and 200 mg/mL of MECE dissolved in 5% Tween 20. Ulcer was induced with 5 mL/kg of ethanol and stomach tissue was obtained after 1 hour. Histological examination was done on hematoxylin and eosin, periodic acid-Schiff, and immunochemically stained gastric mucosal tissues. Prostaglandin E2, superoxide dismutase, catalase, glutathione peroxidase, and lipid peroxidation levels of the gastric tissue homogenates were also determined. Significantly (P<0.05 smaller ulcer areas, less intense edema, and fewer leukocytes’ infiltration were observed in MECE- and omeprazole-treated than in untreated gastric mucosa with ulcer. The gastric pH, mucus production, superoxide dismutase, catalase, and glutathione peroxidase contents increased, while the lipid peroxidation content decreased as a result of MECE treatment. Bcl-2-associated X protein was underexpressed, while heat shock protein 70 and transforming growth factor-beta protein were overexpressed in the ulcerated gastric mucosa tissues treated with omeprazole and MECE.

    Peptic ulcer perforation is a serious complication of peptic ulcer disease with a significant morbidity and mortality. To evaluate 76 patients operated for peptic ulcer perforation and analyse the associated factors in Zewditu Memorial Hospital, Addis Ababa from September 2006 to August 2008. A retrospective analysis of medical records of 76 patients who were operated up on for perforated peptic ulcer over a two year period (2006-2008). The male to female ratio was 6.6:1 with a mean age being 31.5 years. The most common presenting symptom was abdominal pain in 76 (100%) patients. History of smoking and khat chewing was documented in 53/64 (82.8%) and 48/64 (75%) of the patients respectively. Twenty five per cent of the patients gave no history of previous peptic ulcer disease. Seventy patients (92.1%) presented after 48 hours of their illness. The mean hospital stay was 14.5 days. Leucocytosis was found in 31.6% of the cases. Sixty five (85.5%) patients had duodenal ulcer perforation. Postoperative complications occurred in 24 (31.6%) patients. Twelve (15.8%) patients died in the hospital. Early presentation of patients and change in life style may reduce morbidity and mortality in patients with peptic ulcer perforation.

Forty clean-grade SD rats were randomly divided into a normal group, a model group, a stomach meridian group and a gallbladder meridian group, ten rats in each one. Except the normal group, rats in the remaining groups were applied the restraint-cold stress method to establish the model of gastric ulcer. Rats in the normal group and model group received no treatment; rats in the stomach meridian group were treated with EA at "Liangmen" (ST 21) and "Zusanli" (ST 36); rats in the gallbladder meridian group were treated with EA at "Riyue" (GB 24) and "Yanglingquan" (GB 34). The EA was given for 30 min, once a day for 7 days totally. The change of gastric mucosal morphology was observed by routine light microscope; enzyme linked immunosorbent assay was used to detect the expressions of malondialdehyde (MDA), glutathione peroxidase (GSH-px) and tumor necrosis factor-α (TNF-α), interleukin-2(IL-2), interleukin-6(IL-6) in serum and gastric mucosal cells of rats.

We aimed to investigate whether chronic (28-day supplementation with AG could protect against ethanol-induced ulcer in gastric tissue. Furthermore, we investigated the possible molecular mechanisms leading to AG-mediated gastric mucosal protection. We randomized 32 male Wistar rats into four groups for treatment (n = 8 per group: supplementation with water (vehicle and low-dose (AG-1X, medium-dose (AG-2X and high-dose (AG-5X AG at 0, 250, 500, and 1250 mg/kg, respectively. In the first experiment, animals were fed vehicle or AG treatments for 4 weeks. At day 29, 75% ethanol was given orally to each animal at 10 mL/kg to induce gastric ulceration for 2 h. In a second experiment, animals were pretreated orally with each treatment for 1 hr before a single oral administration of ethanol (70%, 10 mL/kg. Trend analysis revealed that AG treatments inhibited ethanol-induced gastric mucosal damage. AG supplementation dose-dependently decreased the pro-inflammatory levels of interleukin 1β and cyclooxygenase 2 and the expression of pro-apoptotic proteins tBid, cytochrome C, and caspases-9 and -3 and increased the levels of anti-apoptotic proteins Bcl-2, Bcl-xL and p-Bad.

    Full Text Available Abstract Background With an incidence of less than 5%, type II paraesophageal hernias are one of the less common types of hiatal hernias. We report a case of a perforated prepyloric gastric ulcer which, due to a type II hiatus hernia, drained into the mediastinum. Case presentation A 61-year old Caucasian man presented with acute abdominal pain. On a conventional x-ray of the chest a large mediastinal air-fluid collection and free intra-abdominal air was seen. Additional computed tomography revealed a large intra-thoracic air-fluid collection with a type II paraesophageal hernia. An emergency upper midline laparotomy was performed and a perforated pre-pyloric gastric ulcer was treated with an omental patch repair. The patient fully recovered after 10 days and continues to do well. Conclusion Type II paraesophageal hernia is an uncommon diagnosis. The main risk is gastric volvulus and possible gastric torsion. Intrathoracic perforation of gastric ulcers due to a type II hiatus hernia is extremely rare and can be a diagnostic and treatment challenge.

     Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

    Peptic ulcer disease is a multifactorial health problem, and its prevalence and risk factors have changed considerably within the past century. To determine the prevalence of peptic ulcer among the population of Arar city and to identify risk factors for peptic ulcer and to estimate their relative impact on ulcer incidence. A cross-sectional study was carried out on the population of Arar city, Northern Saudi Arabia from November 01, 2016 to April 30, 2017. Data were analyzed by SPSS version 16, using descriptive statistics, prevalence, and Chi-square test. Total prevalence of peptic ulcer among the studied respondents was thus: 21.9% had peptic ulcer; 16.2% gastric ulcer and 5.6% duodenal ulcer. In 19.7% of the cases, the pain was severe, 92.4% reported that pain was precipitated by certain food. In addition to heartburn, 78.8% reported loss of appetite, 71.2% indigestion, 66.7% regurgitation, 59.1% nausea and vomiting and 42.4% with chest pain. Regarding the risk factors, coffee drinking came in first place (81.8%) followed by physical stress in 77.3%, spicy food in 57.6%, prolonged use of Non-steroidal anti-inflammatory drugs (NSAIDs) in 33.3% and Helicobacter pylori (H. pylori) infection in 24.2%. A further 22.7% reported melena as a complication while only 10.6% reported hematemesis. This is the first population-based study in Arar, Northern Saudi Arabia reporting point prevalence of peptic ulcer disease. The rate of 16.2% for gastric ulcer and 5.6% for duodenal ulcers are substantially high. Coffee drinking, physical stress, spicy food, prolonged use of NSAID and H. pylori infection were the reported risk factors. Population-based endoscopic studies are recommended.

    There is a close relationship between Helicobacter pylori (H pylori)-specific factors and different gastroduodenal diseases. The present study aimed to investigate the prevalence of vacA d1, d2 genotypes in the H pylori isolates from patients with gastric adenocarcinoma, peptic ulcer disease (PUD) and gastritis in East Azerbaijan region, where the incidence of gastric cancer (GC) is high. Strains isolated from this area are likely to be of European ancestry. In this study, genotyping of the vacA d region of 115 isolates obtained from patients with different gastrodoudenal diseases was accomplished by PCR methods. In addition to PCR amplification of H pylori 16S rDNA, rapid urease tests or histological examination were used to confirm the presence of H pylori in biopsy specimens. Data were collected and analyzed using SPSS version 19. Of the total of 83 H pylori isolates, 36 (43.4%) contained the d1 allele and 47 (56.6%) were subtype d2. The results of the multiple linear/logistic regression analysis showed high correlation between allele d1 and gastric adenocarcinoma or PUD. This study suggests that the H pylori vacA d1 genotype helps predict risk for gastric adenocarcinoma and PUD in East Azerbaijan, Iran.

    Andrographolide sodium bisulfite (ASB), a water-soluble sulfonate of andrographolide has been shown to possess anti-inflammatory, antipyretic and analgesic activities. However, there is no report on the gastroprotective effect of ASB against indomethacin-induced gastric ulcer. Here we investigated the possible anti-ulcerogenic potential of ASB and the underlying mechanism against indomethacin-induced gastric ulcer in rats. The ulcer area, histopathological assessment, contents of gastric mucosal glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), malonaldehyde (MDA) and prostaglandin E2 (PGE2) were examined. In addition, cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2) mRNA expression and immunohistochemical evaluation of HSP70, Bcl-2 and Bax proteins were also investigated. Results indicated that ASB pre-treatment significantly reduced the ulcer areas induced by indomethacin compared with the vehicle group. The gastric levels of GSH, CAT and SOD were markedly increased by ASB while the level of MDA was decreased. In addition, ASB pretreatment significantly promoted the gastric PGE2 levels and up-regulated the COX-1 and COX-2 mRNA expression in comparison with the vehicle group. Immunohistochemistry analysis showed obvious up-regulation of HSP70 and Bcl-2 protein expression while suppression of Bax protein in the gastric tissue of ASB-pretreated group. Taken together, these findings indicated that the gastroprotective effect of ASB might be associated with the improvement of antioxidative status, activation of COX-mediated PGE2 synthesis, down-regulation of Bax proteins and up-regulation of Bcl-2 and HSP70 proteins. ASB might have the potential for further development as a promising alternative for antiulcer treatment. Copyright © 2015 Elsevier B.V. All rights reserved.

    Meniscus-like presentation of ulcerating gastric carcinoma on upper gastrointestinal series radiograph was first described in 1921 by Carman and has since been known as a useful differential diagnostic sign in radiology. In 1982 using then newly introduced computed tomography (CT) Widder and Mueller revisited the meniscus sign. Their study was primarily focused on a dynamic assessment of the demonstrability of the meniscus sign that largely depends on the judgment and technical skill of examiner, especially graded compression and patient positioning. One year earlier Balfe et al. assessed the diagnostic reliability of gastric wall thickening as observed on CT scan in adenocarcinoma, lymphoma and leiomyosarcoma and concluded that it is not a reliable finding. In contrast, however, Lee et al. recently emphasized that the wall thickness measurement on CT of exophytic carcinoma, myoma and ulcers was a useful diagnostic means. Thus, it appears that gastric wall thickening or mucosal heave-up is by itself not as reliable as the meniscus sign. The electronic search of world literature failed to disclose earlier report of this sign demonstrated by 18 F-FDG positron emission tomography and computed tomography (PET/CT). The present communication documents 18 F-FDG PET/CT finding of the meniscus sign as encountered in a case of ulcerating gastric carcinoma, the histological diagnosis of which was moderately differentiated tubular adenocarcinoma. Unlike most gastric tumors without ulceration that tend to unimpressively accumulate 18 F-FDG the present case of Borrmann type III gastric carcinoma demonstrated markedly increased 18 F-FDG uptake

    The effect on the recurrence of gastric ulcers after suppression of Helicobacter pylori by combined treatment with cimetidine and the antimicrobial drug cefixime was investigated. Twenty one of 43 patients with endoscopically proved gastric ulcer and H pylori infection were randomly assigned to receive cimetidine 800 mg daily for 12 weeks; the remaining 22 patients received cimetidine 800 mg daily for 12 weeks plus cefixime 100 mg daily for the last two weeks. After treatment, 88% of 17 patients on cimetidine only remained H pylori positive, whereas combined administration of cimetidine and cefixime had suppressed H pylori in 78% of 18 patients (p less than 0.05). Seventeen patients in the former group whose ulcers healed but who remained H pylori positive and 18 patients in the latter group whose ulcers healed and who were no longer infected with H pylori continued to be followed after treatment. These patients underwent endoscopy to detect ulcer recurrence if symptomatic, or at 12 and 24 weeks if asymptomatic. At 12 weeks, recurrence was observed in seven of 15 (47%) patients in whom H pylori persisted, but in only one of 14 (7%) patients in whom H pylori had been suppressed (p less than 0.05). At 24 weeks, however, recurrence rates were similar between the two groups. These findings indicate that H pylori infection may be closely related to early ulcer recurrence.

    Advancements in medical care for peptic ulcer disease (PUD) have reduced the need for invasive surgical procedures such as gastric resection (GR). Community-based PUD studies from a large sampling of PUD patients designed to analyze hospital resource use and outcomes after different surgical procedures have been rare. We aimed to exhaustively reappraise the risk factors and patient demographics that affect PUD patient recoveries after GR compared to those after simple closure (SC). We used a Japanese administrative database for 6 consecutive months each year between 2006 and 2010. The database included a total of 68,432 PUD patients; we analyzed 6,334 perforation cases and 3,148 cases of patients who underwent GR or SC. Study variables were demographics, comorbidities, characteristics of PUD, and operative day. Study outcomes that were analyzed included mortality, postoperative complications, ventilation administration, postoperative blood transfusions, length of stay, total charges, operating room (OR) time, and the postoperative fasting period (defined as the day of surgery to the day oral food intake was resumed.) To reduce selection bias in study procedures and to control the variation in hospital practice, a propensity score (PS) matching cohort analysis and a mixed linear regression model were used to assess the effects of GR on the outcomes. In 699 hospitals, 322 GRs and 2,826 SCs were observed. Younger age, duodenal ulcers, preexisting anemia and an operative day no more than 24hours were significant associated with the choice of SCs. No significant differences were observed in study outcomes after either GR or SC; more postoperative blood transfusions and longer OR times but shorter postoperative fasting periods were observed after GR. Longer OR times, ventilation and postoperative blood transfusion were significantly associated with mortality. Not GR but longer OR times use of ventilation and complications were the most significant indicators of increased

    Full Text Available Abstract Background The association between proinflammatory cytokine gene polymorphisms and gastric diseases related to Helicobacter pylori varies by population and geographic area. Our objective was to determine if the IL-1B -511 T>C and -31 C>T polymorphisms and H. pylori vacA genotypes are associated with risk of chronic gastritis and gastric ulcer in a Mexican population. Methods We conducted endoscopic studies in 128 patients with symptoms of dyspepsia. We took two biopsies from the body, antrum, or ulcer edge from each patient, and classified our histopathological findings according to the Sydney System. H. pylori infection and vacA genotyping were accomplished via PCR from total DNA of the gastric biopsies. We confirmed the presence of anti-H. pylori serum IgG and IgM in 102 control subjects. In both case subjects and control subjects, the IL-1B -511 T>C polymorphism was genotyped by PCR-RFLPs and the IL-1B -31 C>T polymorphism was genotyped by pyrosequencing. Results Sixty-two point seven (62.7% of the 102 control subjects were H. pylori-seropositive. Among the case subjects, 100 were diagnosed with chronic gastritis and 28 with gastric ulcer. We found that 77% of the patients with chronic gastritis and 85.7% of the patients with gastric ulcer were H. pylori-positive. The predominant H. pylori genotype was vacA s1m1 (58.4% and the most frequent subtype was vacA s1. The -511 TC, (rs16944 -511 T>C genotype and the -511C allele were associated with chronic gastritis (OR = 3.1, 95% CI = 1.4-6.8 and OR = 3.0, 95% CI = 1.4-6.0, respectively. The subjects carrying -31T (rs1143627 -31 C>T were found to be at a higher risk of having chronic gastritis (OR = 2.8, 95% CI = 1.3-5.8. The IL-1B -511C/-31T haplotype was associated with chronic gastritis (OR = 2.1, 95% CI = 1.2-3.8 but not with gastric ulcer. Conclusions The H. pylori vacA genotypes identified herein were similar to those reported for other regions of Mexico. The vacA s1m1 genotype was

    This research was conducted to evaluate the hypothesis that gastric ulcers caused by the NSAID diclofenac sodium (DCF) can be prevented by the soluble epoxide hydrolase inhibitor TPPU. Mice were administered a single dose of 10, 30 or 100mg/kg of DCF. Once an ulcerative dose of DCF was chosen, mice were pretreated with TPPU for 7days at 0.1mg/kg to evaluate anti-ulcer effects of the sEH inhibitor on anatomy, histopathology, pH, inflammatory markers and epithelial apoptosis of stomachs. Diclofenac caused ulceration of the stomach at a dose of 100mg/kg and a time post dose of 6h. Ulcers generated under these conditions were associated with a significant increase in the levels of TNF-α and IL-6 in serum and increased apoptosis compared to control mice. Pretreatment with TPPU resulted in a decrease of ulceration in mice treated with DCF with a significant decrease in the level of apoptosis, TNF-α and IL-6 in the serum in comparison to diclofenac-treated mice. TPPU did not affect the pH of the stomach, whereas omeprazole elevated the pH of the stomach as expected. A similar anti-ulcer effect was observed in sEH gene knockout mice treated with DCF. The sEH inhibitor TPPU decreases the NSAID-induced stomach ulcers. Copyright © 2017 Elsevier Inc. All rights reserved.

    Aim: To study the association of Helicobacter pylori infection with chronic antral gastritis in peptic ulcer disease patients and healthy population of Kashmir. Methods: 50 peptic ulcer patients (duodenal ulcer = 46, gastric ulcer = 2 and combined duodenal and gastric ulcer = 2) and 30 asymptomatic healthy volunteers were included in this study. Peptic ulcer was diagnosed on endoscopic examination. 4–6 punch biopsies were taken from gastric antrum in all the individuals and in case of gastric ulcer an additional biopsy was taken from the edge of the ulcer to exclude its malignant nature. Helicobacter pylori (H. pylori) organism was diagnosed using three different test methods, viz. Histology (using Giemsa Stain), Microbiology (Gram Stain) and Biochemistry (using one minute Endoscopy Room Test). Histological diagnosis of H. pylori was taken as the “gold standard” for the presence of H. pylori organism. Histological diagnosis of gastritis was made using Hematoxylin and Eosin Stain and the gastritis was classified as active chronic gastritis and superficial chronic gastritis. Results: Out of 30 peptic ulcer disease patients with associated antral gastritis, 27 (90%) were positive for H. pylori on histological examination (13 superficial chronic gastritis and 14 active chronic gastritis) whereas out of 8 healthy volunteers with histological evidence of chronic antral gastritis, H. pylori was observed in 7 individuals (87.50%) (4 active chronic gastritis and 3 superficial chronic gastritis). Conclusion: A highly significant association between H. pylori infection with chronic antral gastritis both in peptic ulcer disease patients and healthy volunteers of Kashmir was found in this study. Association between H. pylori infection and chronic gastritis was 90% in peptic ulcer group and 87.50% in healthy population (P<0.005). PMID:18493464

    Excessive alcohol consumption can lead to gastric ulcer and the present work was aimed to examine the protective effect of tetrahydrocoptisine (THC) in the model of ethanol-induced gastric ulcer in mice. Fasted mice treated with ethanol 75% (0.5 ml/100 g) were pre-treated with THC (10 or 20 mg/kg, ip), cimetidine (100 mg/kg, ip) or saline in different experimental sets for a period of 3 days, and animals were euthanized 4 h after ethanol ingestion. Gross and microscopic lesions, immunological and biochemical parameters were taken into consideration. The results showed that ethanol induced gastric damage, improving nitric oxide (NO) level, increased pro-inflammatory cytokine (TNF-α and IL-6) levels and myeloperoxidase (MPO) activity, as well as the expression of nuclear factor-κB (NF-κB) in the ethanol group. Pretreatment of THC at doses of 10 and 20 mg/kg bodyweight significantly attenuated the gastric lesions as compared to the ethanol group. These results suggest that the gastroprotective activity of THC is attributed to reducing NO production and adjusting the pro-inflammatory cytokine, inhibited neutrophil accumulation and NF-κB expression. - Highlights: • THC decreased ethanol-induced pro-inflammatory cytokine release. • THC inhibited the production of NO in serum and gastric tissue. • THC reduced NF-κB expression and MPO accumulation in ethanol-induced gastric tissue.

    The frequency of occurrence of Helicobacter pylori type I strains in isolates from Austria and Portugal and different polymerase chain reaction-based approaches to detect the cag pathogenicity island were assessed. Of the 41 Austrian strains, eight of 14 (57.2%) isolated from patients with gastritis, 14 of 19 (73.7%) from patients with peptic ulcer and eight of eight (100%) from patients with gastric cancer were type I strains. Among the Portuguese strains, eight of 14 (57.2%) isolated from patients with gastritis, ten of 12 (83.3%) from patients with peptic ulcer and five of 13 (38.5%) from patients with gastric cancer were classified as type I. Thus, Helicobacter pylori type I strains occur frequently in both populations but show no significant correlation with peptic ulcer disease. The prevalence of the type Igenotype in Austrian cancer patients, however, was significantly higher (P=0.007). The cagE-specific polymerase chain reaction was found to be a reliable and efficient method for detection of the cag pathogenicity island.

    Peptic ulcer disease is the cause of dyspepsia in about 10% of people. Ninety-five percent of duodenal and 70% of gastric ulcers are associated with Helicobacter pylori. Eradication of H. pylori reduces the relapse rate of ulcers but the magnitude of this effect is uncertain. This is an update of Ford AC, Delaney B, Forman D, Moayyedi P. Eradication therapy for peptic ulcer disease in Helicobacter pylori-positive patients. Cochrane Database of Systematic Reviews 2006, Issue 2. Art. No.: CD003840. DOI: 10.1002/14651858.CD003840.pub4. To assess the proportion of peptic ulcers healed and the proportion of participants who remained free from relapse with eradication therapy against placebo or other pharmacological therapies in H. pylori-positive people.To assess the proportion of participants that achieved complete relief of symptoms and improvement in quality of life scores.To compare the incidence of adverse effects/drop-outs (total number for each drug) associated with the different treatments.To assess the proportion of participants in whom successful eradication was achieved. In this update, we identified trials by searching the Cochrane Central Register of Controlled Trials (CENTRAL), Ovid MEDLINE (1950 to March 2016) and Ovid EMBASE (1980 to March 2016). To identify further relevant trials, we handsearched reference lists from trials selected by electronic searching, and published abstracts from conference proceedings from the United European Gastroenterology Week (published in Gut) and Digestive Disease Week (published in Gastroenterology). The search was last updated in March 2016. We contacted members of Cochrane Upper GI and Pancreatic Diseases, and experts in the field and asked them to provide details of outstanding clinical trials and any relevant unpublished materials. We analysed randomised controlled trials of short- and long-term treatment of peptic ulcer disease in H. pylori-positive adults. Participants received at least one week of H. pylori

    This study was designed to test the hypothesis that thyroid states may affect the acute development of gastric lesions induced by cold-resistant stress. Normal (euthyroid), hyperthyroid and hypothyroid rats were used. Gastric lesion incidence and severity was significantly increased in hypothyroid rats, whereas in contrast hyperthyroid rats developed significantly less gastric lesions. As anticipated, plasma levels of thyroxin (T/sub 4/) were significantly elevated in hyperthyroid rats, and undetectable in hypothyroid rats. Acute pretreatment with i.p. cimetidine, but not T/sub 4/ 1 h prior to stress completely prevented gastric lesions formation in hypothyroid rats. Finally, binding of /sup 3/H-dihydroalprenolol to ..beta..-adrenergic receptors on brain membranes prepared from frontal cortex was reduced by 20% in hypothyroid rats after 3 h of stress. These and other data contained herein suggest that thyroid hormones contribute to modulate the responsiveness of the gastric mucosa to stress. The increase rate of ulcerogenesis observed in hypothyroid rats appears to be mediated by gastric acid secretion. The central mechanism for this response may involve decreased brain nonadrenergic receptor function.

    Helicobacter pylori (H. pylori) infection is widely accepted as the most important factor in the pathogenesis of duodenal ulcer. However, in parallel with more effective eradication of H. pylori, the prevalence of H. pylori is changing, and H. pylori-negative peptic ulcer disease appears to be increasing. When making a diagnosis of H. pylori-negative peptic ulcer disease, it is essential to avoid misclassification because of inaccurate diagnosis. In addition, secondary causes may need to be excluded with appropriate investigations. In the absence of H. pylori, nonsteroidal anti-inflammatory drug usage is the most common cause of peptic ulcer; surreptitious nonsteroidal anti-inflammatory drug usage is a cause of unexplained ulcer disease in up to 60% of patients. Hypersecretory syndromes such as Zollinger-Ellison syndrome, although rare, need to be excluded. Once all known etiological factors are excluded, there remains a group of patients with so-called "idiopathic ulcers." The interplay of etiological factors in the pathogenesis of idiopathic peptic ulcer disease is poorly defined but may include a genetic predisposition, altered acid secretion, rapid gastric emptying, defective mucosal defense mechanisms, psychological stress, and smoking. The management of idiopathic peptic ulcers is not defined; they appear to be more resistant to standard therapy, can be associated with more frequent complications, and those that relapse may require long-term maintenance therapy.

    The common acid related diseases of the upper GI tract could be considered as primarily due to the defect in barrier function either of the gastric mucosal or duodenal epithelium leading to the formation of gastric or duodenal ulcers. An attempt was made in this chapter to discuss the history of peptic ulcer disease in humans and methods for the production of acute gastric lesions and ulcers in experimental animals with the special attention focused to the contribution of Polish scientists and investigators into this field. Early surgical advances in the management of peptic ulcers were emphasized that were then subsequently replaced by pharmacological treatment (histamine H(2)-receptor antagonists, proton pump inhibitors) and considered as the major strategy against the acid disorders. This included the immense body of work performed by numerous group of investigators, including Polish researchers, to identify the effects of acid, bile salts, aspirin and other non-steroidal anti-inflammatory drugs (NSAID), stress, Helicobacter pylori (H. pylori) infection, prostaglandins (PG) and nitric oxide (NO) on the integrity of the gastrointestinal mucosa, which all were discussed in this chapter. The concept of major defensive mechanism in the stomach called "cytoprotection", originally proposed by Andre Robert is recalled in the relevance to the great contribution of Polish scientist working at the Jagiellonian University in Cracow. These experimental studies gave a new insight into the mechanism of action of arachidonate cascade products such as PGs, tromboxanes and leukotrienes and had opened the new therapeutic avenues for the gastroprotective treatment of the acute gastric mucosal damage. Detailed studies revealed, however, that PG-induced cytoprotection offers a short-term protection against gastric lesions induced by corrosive agents but unfortunately this phenomenon gives a little, if any, impact to the process of ulcer healing. The experimental studies on healing

    Experimental models of chronic and acute peptic ulcerations were produced in the albino rats by means of prolonged starvation and indomethacin administration. In the case of acute indomethacin-induced peptic ulceration, the effects of anticholinergic drugs on the ulcers produced were also studied. Starving the rats for a period of seven days produced gastric ulceration in all the rats used while indomethacin produced gastric ulceration within five hours in all the rats used. Severe ulceration of the degree found in human peptic ulcer disease was produced only by chronic starvation. Anticholinergic drugs ameliorated indomethacin-induced gastric ulceration, partly at least, by reducing intra-gastric acidity.

    In patients with duodenal ulcer, mucosal blood flow of pentagastrin-stimulated stomach was studied using sup(99m)Tc-methylaminophenazone clearance technique published previously by the authors. Comparative investigations were carried out in active and inactive phases of the disease and in operated patients before and after highly selective vagotomy. The relation between gastric mucosal blood flow and acid secretion proved to be different from that of the normacid controls: in duodenal ulcer patients the secretory capacity in relation to the blood supply proved to be increased. Both the mucosal blood flow and acid secretion values were elevated in the active stage as compared to the inactive phase, while the proportion between them remained unchanged. The relation of secretion to mucosal blood flow after highly selective vagotomy became similar to that of the normal controls. It is suggested that the sup(99m)Tc-methylaminophenazone clearance method is a suitable tool to evaluate the effectiveness of vagotomy. (author)

In these rats cysteamine induced ulcerations in the stomach.......Cysteamine is a potent duodenal ulcerogen in rats. It has been demonstrated to inhibit gastric empyting, whose role in ulcer formation is unknown. In the present study the effect of cysteamine on gastric motility and emptying rate in rats was studied by direct fluoroscopic observation. The delayed...... gastric empyting was due to a pronounced relaxation of the stomach and a complete blocking of gastric peristalsis. These effects have their maximum within the first 4 h after administration of cysteamine. Thereafter peristalsis and gastric empyting slowly return. In controls contrast medium administered...

    Full Text Available Abstract Background The leaves and root of Flabellaria paniculata (Malpighiaceae are frequently used in the treatment of wounds and ulcers in Nigerian folk medicine. The purpose of this study was to compare the effect of ethanolic extracts from the leaves (FPL and root (FPR of F. paniculata on gastric ulcers in rats. Methods The effect of FPL and FPR (100, 200 and 400 mg/kg was evaluated in ethanol and indomethacin gastric ulcer models. Control groups for FPL and FPR were orally treated with 3% Tween 20 and distilled water respectively. FPL was further investigated in pylorus ligation model. Misoprostol and cimetidine were used as reference. Results FPL significantly (P 50 of FPL was estimated to be 4570 mg/kg while that of FPR was 2754 mg/kg. The LD50 in intraperitoneal injection was estimated to be 1202.26 and 1380.38 mg/kg for FPL and FPR respectively. The phytochemical investigation showed that both extracts possess triterpenoids and saponin, while the presence of flavonoid was detected only in FPL. Conclusions The results of this study indicated that FPL and not FPR is effective against experimentally induced gastric ulcers. The presence of varied phytochemical constituents probably influenced the pharmacological differences between the two extracts.

    Full Text Available Renal cell carcinoma (RCC accounts for approximately 3% of all adult malignancies. True gastrointestinal metastases, specifically to gastric wall, have been rarely observed. Herein we describe a case of delayed metastasis to gastric wall occurring more than a decade after previously curative nephrectomy for RCC. A 67-year-old male with history of right radical nephrectomy in 2001 for RCC was found to have an asymptomatic right lower lobe solitary lung mass upon routine follow-up in 2011, with final biopsy results showing metastatic RCC for which he was treated accordingly. In 2014, patient was evaluated for dyspepsia with microcytic anemia and underwent an esophagogastroduodenoscopy and colonoscopy. EGD revealed a solitary one-centimeter atypical ulcer in the posterior mid gastric body with biopsy results being consistent with metastatic RCC. Our literature review has yielded thirty-six reported cases of RCC in association with gastric wall metastases.

    Background The objectives of this study were to evaluate the effects of two commercial feed supplements, Egusin 250® [E-250] and Egusin SLH® [E-SLH], on gastric ulcer scores, gastric fluid pH, and blood gas values in stall-confined horses undergoing feed-deprivation. Methods Nine Thoroughbred horses were used in a three-period crossover study. For the three treatment groups, sweet feed was mixed with E-250, E-SLH, or nothing (control group) and fed twice daily. Horses were treated for 21 days, then an additional 7 days while on an alternating feed-deprivation model to induce or worsen ulcers (period one). In periods two and three, horses (n=6) were treated for an additional 7 days after feed-deprivation. Gastroscopies were performed on day -1 (n=9), day 21 (n=9), day 28 (n=9) and day 35 (n=6). Gastric juice pH was measured and gastric ulcer scores were assigned. Venous blood gas values were also measured. Results Gastric ulcers in control horses significantly decreased after 21 days, but there was no difference in ulcer scores when compared to the Egusin® treated horses. NG gastric ulcer scores significantly increased in E-250 and control horses on day 28 compared to day 21 as a result of intermittent feed-deprivation, but no treatment effect was observed. NG ulcer scores remained high in the control group but significantly decreased in the E-SLH- and E-250-treated horses by day 35. Gastric juice pH values were low and variable and no treatment effect was observed. Mean blood pCO2 values were significantly increased two hours after feeding in treated horses compared to controls, whereas mean blood TCO2 values increased in the 24 hour sample, but did not exceed 38 mmol/l. Conclusions The feed-deprivation model increased NG gastric ulcer severity in the horses. However, by day 35, Egusin® treated horses had less severe NG gastric ulcers compared to untreated control horses. After 35 days, Egusin® products tested here ameliorate the severity of gastric ulcers in

    It is uncertain whether eradication of Helicobacter pylori--without a prolonged suppression of acid secretion--is sufficient to allow healing of peptic ulcers. We evaluated whether eradication of H. pylori with no following anti-secretory medication then administered is sufficient for treatment of peptic ulcers. We also looked at the impact of non-steroidal anti-inflammatory drug (NSAID) and acetylsalicylic acid (ASA) use on ulcer relapses. The effect of eradication on ulcer healing and relapse rate was analysed in 115 patients, randomly allocated to four treatment groups: (1) quadruple therapy (28); (2) dual therapy (n-30); (3) triple therapy (n=27); and (4) lansoprazole and placebo (n=30). Endoscopic assessment was performed at 0, 8, and 52 weeks. The ulcer healing rate was 100% [95% confidence interval (CI), 95-100%] in H. pylori-negative and 83% (95% CI, 67-94%) in H. pylori-positive patients (PUlcer relapses occurred in 5% (95% CI, 1-13%) of H. pylori-negative and in 36% (95% CI, 19-56%) of H. pylori-positive patients (P ulcer relapse rate was 30% (95% CI, 7-65%), whereas the ulcer relapse rate was 2% (95% CI, 0.4-10%) in patients who did not use NSAIDs or ASA (P ulcer relapse rate in H. pylori-positive patients who used or did not use NSAIDs or ASA was found. The eradication rate of H. pylori was 93% (95% CI, 76-99%) in the quadruple therapy group, 83% (95% CI, 64-94%) in the dual therapy group, 100% (95% CI, 87-100%) in the triple therapy group, and 0% (95% CI, 0-12%) in the lansoprazole and placebo group. Eradication treatment for H. pylori-positive gastric or duodenal ulcer is sufficient, with no need to follow it with anti-secretory medication. Cure of the infection reduces ulcer relapses in patients who did not use NSAIDs or ASA.

    Full Text Available Holothuria arenicola is the most important and abundant sea cucumber species in the Mediterranean Sea on the Egyptian coast. This work aimed to investigate the prophylactic and the curative effects of H. arenicola extract HaE (200 mg/kg on gastric mucosal damage following indomethacin and cold stress in healthy rats. Sixty-four rats were randomly divided into four main groups. Rats of the first group (8 rats/group were administered distilled water orally (control group, rats of the second group (8 rats/group were administered single oral dose of indomethacin (150 mg/kg and exposed to cold stress (4 ± 1 °C for 30 min to induce gastric ulcer (GU model (ulcer group, rats of the third group, prophylactic group (24 rats/group were treated with HaE and/or ranitidine (RAN and then exposed to GU and rats of the fourth group, curative group (24 rats/group were exposed firstly to GU and then treated with HaE and/or RAN. The results clearly indicate that pre-treatment with HaE and/or ranitidine significantly decreases the ulcer index, showing 72.50%, 53.11% and 80.56% ulceration inhibition, respectively. However, post-treatment with HaE and/or ranitidine significantly decreases the ulcer index, showing 51.66%, 62.41% and 67.78% ulceration inhibition, respectively. The results also showed that pre and post-treatment with HaE and/or RAN significantly decreased gastric malondialdehyde (MDA level and enhanced reduced glutathione (GSH, catalase (CAT, glutathione-S-transferase (GST and superoxide dismutase (SOD levels. The results clearly indicate that pre-treatment with HaE is preferable.

    According to an estimation of the WHO, almost 80% of people globally are treated by traditional medicine. We evaluated the anti-ulcerogenic potential of Salmalia malabarica extract in rats using aspirin-, alcohol- and pylorus ligation-induced ulcer models. Two different doses (200 and 400 mg/kg body weight) of Salmalia malabarica extract was administered intraperitoneally (i.p.) to all 3 ulcer-induced models for 5 consecutive days. The anti-ulcerogenic potential in rats treated with 2 doses of Salmalia malabarica extract and omeprazole (20 mg/kg, i.p.) was determined and compared to the control groups. Salmalia malabarica extract showed a significant decrease in ulcer index as compared to the control group in a dose-dependent manner. Salmalia malabarica extract also showed protection of 66.22% and 74.54% in asprin-, 73.79% and 78.14% in alcohol- and 68.94% and 78.84% in pylorus ligation-induced ulcers. However, omeprazole showed protection of 84.73%, 85.5% and 86.12% in aspirin-, alcohol- and pylorus ligation-induced ulcers, respectively. Furthermore, Salmalia malabarica extract significantly decreased the volume of gastric juice, free and total acidity, whereas it increased gastric pH when directly compared to the control group. Conclusively, Salmalia malabarica possesses anti-ulcerogenic, antisecretory, and cytoprotective potential and can be used as a supplement for the treatment of gastric ulcers in a dose dependent manner.

    Peptic ulcer, the common disease of the upper gastro-intestinal tract, occurs in about 5-10% of the world's population. Therefore, diagnosis of trace disease progression with a noninvasive method is of prime importance in the field of healthcare research. The aim of this study was to evaluate the validity of salivary enzymes as noninvasive biomarkers for peptic ulcer. In practice, 34 peptic ulcer patients and 30 healthy subjects donated their un-stimulated saliva samples after 8 h of fasting. The activity of some selected enzymes was measured using appropriate enzymatic assay methods. The results indicated an overall alternation in enzymatic activity of saliva in patients suffering from peptic ulcer. Biological activity of a-amylase, peroxidase and lactate dehydrogenase, showed significantly higher values in almost all patients as compared to control subjects. Based on the results of salivary enzyme activity, it was concluded that besides the influence of their peptic ulcer on enzyme activity of saliva, the considerably higher activity of a-amylase could also be related to the major role of the enzyme on physiological oxidative stress.

    Full Text Available Objetive. To determine the influence of corn oil on the volatile fatty acids (VFA concentrations in the gastric juice in horses with phenylbutazone (PBZ induced gastric ulcers and Correlate the gastroscopic findings with the VFA concentrations. Materials and methods. 15 horses were allotted in 3 groups. Group I (control received placebo during first 6 days (induction period and was treated with sucralfate for 2 weeks (treatment period. Groups II and III received PBZ during the induction phase. After 6 days, horses from group II received 70 mL of corn oil /100 kg of body weight/ po, twice a day, for 2 weeks and horses from group III received 90 mL of corn oil/100 kg of body weight/ po, twice a day, for 2 weeks. All horses were examined by gastroscopy at days 0, 7 and 21. The lesions were recorded and classified according to the number and severity. Samples from gastric fluid were taken to measure the concentrations of the acetic, propionic, butyric and lactic acids. Results. Both PBZ protocols produced lesions in the both non-glandular and glandular areas of the stomach. All the treatments produced healing of the injured mucosa glandular. Neither of the two corn oil treatments affected healing of the gastric ulcers located in the non-glandular area. Conclusions. The concentrations of acetic and butyric acids were highest in the gastric juice. The corn oil and sucralfate did not lead to differences in the concentration of acetic acid and butyric acid.

    The efficacy of low-dose lansoprazole has not been established for the prevention of recurrent gastric or duodenal ulcers in those receiving long-term low-dose aspirin (LDA) for cardiovascular and cerebrovascular protection. This study sought to examine the efficacy of low-dose lansoprazole (15 mg once daily) for the secondary prevention of LDA-associated gastric or duodenal ulcers. Patients were randomized to receive lansoprazole 15 mg daily (n = 226) or gefarnate 50 mg twice daily (n = 235) for 12 months or longer in a prospective, multicenter, double-blind, randomized active-controlled trial, followed by a 6-month follow-up study with open-label lansoprazole treatment. The study utilized 94 sites in Japan and 461 Japanese patients with a history of gastric or duodenal ulcers who required long-term LDA therapy for cardiovascular and cerebrovascular disease. The primary endpoint was the development of gastric or duodenal ulcers. The cumulative incidence of gastric or duodenal ulcers on days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 1.5, 2.1, and 3.7%, respectively, in the lansoprazole group versus 15.2, 24.0, and 31.7%, respectively, in the gefarnate group. The risk of ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.099 (95% confidence interval [CI] 0.042-0.230). Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term LDA therapy.

    Anti-inflammatory cytokines play an important role in downregulation of inflammation and the prevention of neoplastic disorders. Genetic variations of anti-inflammatory cytokines are assumed to influence such responses. The aim of the present study was to clarify the association between the IL-10 polymorphism, one of the representative anti-inflammatory cytokines, and susceptibility to gastric cancer and peptic ulcer in Japan. The IL-10-1082 (A/G)/-819 (T/C)/-592 (A/C) polymorphisms were assessed in Helicobacter pylori-positive patients with gastritis only (n = 162), gastric ulcers (n = 110), duodenal ulcers (n = 94), or gastric cancers (n = 105), and H. pylori-negative controls (n = 168) by allele specific primer-polymerase chain reaction methods. The carriage of IL-10-592 C (age and sex-adjusted odds ratio [OR]: 1.851, 95% confidence interval [CI]: 1.018-3.380) and IL-10-819 C (adjusted OR: 1.868, 95%CI: 1.023-3.411) allele were associated with an increased risk for gastric cancer development, not gastric ulcer and duodenal ulcer. The IL-10-1082 polymorphism had no association with development of gastric cancer and peptic ulcers. The presence of the ATA/GCC haplotype of IL-10-1082/-819/-592 polymorphism significantly increased the risk of gastric cancer development (adjusted OR: 2.805, 95%CI: 1.258-6.254) compared with presence of the ATA/ATA haplotype. The IL-10-1082/-819/-592 genotype status and haplotype were associated with an increased risk for gastric cancer development, not peptic ulcer, in Japan. The genotyping test of this anti-inflammatory cytokine would be useful for the detection of individuals with higher risk of gastric cancer development.

    Actinodaphne sesquipedalis Hook. F. Var. Glabra (Kochummen), also known as “Medang payung” by the Malay people, belongs to the Lauraceae family. In this study, methanol leaf extract of A. sesquipedalis was investigated for their acute toxicity and gastroprotective effects to reduce ulcers in rat stomachs induced by ethanol. The rats were assigned to one of five groups: normal group (group 1), ulcer group (group 2), control positive drug group (group 3) and two experimental groups treated with 150 mg/kg (group 4) and 300 mg/kg (group 5) of leaf extract. The rats were sacrificed an hour after pretreatment with extracts, and their stomach homogenates and tissues were collected for further evaluation. Macroscopic and histological analyses showed that gastric ulcers in rats pretreated with the extract were significantly reduced to an extent that it allowed leukocytes penetration of the gastric walls compared with the ulcer group. In addition, an ulcer inhibition rate of >70% was detected in rats treated with both doses of A. sesquipedalis extract, showing a notable protection of gastric layer. Severe destruction of gastric mucosa was prevented with a high production of mucus and pH gastric contents in both omeprazole-treated and extract-treated groups. Meanwhile, an increase in glycoprotein uptake was observed in pretreated rats through accumulation of magenta color in Periodic Acid Schiff staining assay. Analysis of gastric homogenate from pretreated rats showed a reduction of malondialdehyde and elevation of nitric oxide, glutathione, prostaglandin E2, superoxide dismutase and protein concentration levels in comparison with group 2. Suppression of apoptosis in gastric tissues by upregulation of Hsp70 protein and downregulation of Bax protein was also observed in rats pretreated with extract. Consistent results of a reduction of gastric ulcer and the protection of gastric wall were obtained for rats pretreated with A. sesquipedalis extract, which showed its

    Helicobacter pylori (H. pylori) eradication therapy alone is insufficient to ensure healing of large ulcers with H. pylori-positive gastric ulcer (GU). The question of what is the optimum antiulcer treatment following H. pylori eradication therapy has not been fully elucidated. Furthermore, the ulcer healing effects of eradication therapy itself with H. pylori-positive duodenal ulcer (DU) have not been investigated. In GU study, the eradication therapy + proton pump inhibitor (PPI) group (group A) were administered eradication therapy followed by 7 weeks of a PPI, and the eradication therapy + gastroprotective drug (GP) group (group B) eradication therapy followed by 7 weeks of a GP. In DU study, the eradication therapy + PPI group (group C) were administered eradication therapy followed by 5 weeks of a PPI, and the eradication therapy only group (group D) was eradication therapy alone. In GU study, healing rates for ulcer of ≥15 mm in diameter were significant greater in the group A. In DU study, high healing rates were seen both the group C and D. In conclusion, a PPI could significantly heal GU than a GP after eradication therapy in GU. Meanwhile, the eradication alone is sufficient for DU.

    Background Diabetes mellitus is an independent risk factor for impaired healing of peptic ulcers, and there are currently no supplementary therapeutics other than the standard antipeptic medicine to improve the ulcer healing in diabetes. This study examined the potential pleiotropic effect of a glucagon-like peptide (Glp)-1 analogue exendin (Ex)-4 on the regeneration of gastric ulcer in streptozotocin-induced diabetic rats. Methods and results Chronic ulcer was created in rat stomach by submucosal injection of acetic acid and peri-ulcer tissues were analyzed 7 days after operation. Ulcer wound healing was impaired in diabetic rats with suppressed tissue expression of eNOS and enhanced levels of pro-inflammatory reactions. Treatment with intraperitoneal injection of Ex4 (0.5 μg/kg/d) significantly reduced the area of gastric ulcer without changing blood glucose level. Ex-4 restored the expression of pro-angiogenic factors, and attenuated the generation of regional inflammation and superoxide anions. The improvement of ulcer healing was associated with increased expression of MMP-2 and formation of granulation tissue in the peri-ulcer area. Conclusion Administration of Ex4 may induce pro-angiogenic, anti-inflammatory and anti-oxidative reactions in the peri-ulcer tissue of diabetic rats that eventually enhances tissue granulation and closure of ulcerative wounds. Our results support the potential clinical application of Glp-1 analogues as supplementary hypoglycemic agents in the antipeptic ulcer medication in diabetes. PMID:29095895

    Tiao He Yi Wei granule (DHYW), a traditional Chinese medicine, has been used for the treatment of gastric ulcer in clinical setting. The purpose of the present study was to investigate the possible effect of DHYW and explore the underlying mechanism against ethanol-induced gastric ulcer in mice. The model of ethanol-induced gastric ulcer in mice was induced by ethanol (0.2 mL/kg). Administration of DHYW at the doses of 250, 500 mg/kg body weight prior to the ethanol ingestion could effectively protect the stomach from ulceration. The gastric lesions were significantly ameliorated in the DHYW group compared with that in the model group. Treatment with DHYW markedly decreased the levels of interleukin-6 (IL-6), IL-1β, and tumor necrosis factor-α (TNF-α). In addition, DHYW treatment elevated myeloperoxidase (MPO) level in stomach, increased superoxide dismutase (SOD) activity, and decreased malonaldehyde (MDA) content in serum and stomach compared with those in the model group. DHYW significantly inhibited NF-κB pathway expressions in the gastric mucosa ulcer group. Taken together, DHYW exerted a gastroprotective effect against gastric ulceration and the underlying mechanism might be associated with NF-κB pathway. PMID:26779276

    The 13 C-urea breath test ( 13 C-UBT), developed a few decades ago, is widely used as a non-invasive diagnostic method to detect only the presence of the gastric pathogen Helicobacter pylori infection; however, the actual disease state, i.e. whether the person harbouring H. pylori has peptic ulcer disease (PUD) or non-ulcerous dyspepsia (NUD), is still poorly understood. Nevertheless, the present 13 C-UBT has numerous limitations, drawbacks and pitfalls owing to the ingestion of 13 C-labelled external urea. Here, we show that H. pylori is able to utilize the natural 13 C and 18 O-urea inherently present in the gastric juice in humans for its urease activity which has never been explored before. In vitro measurements of isotopic fractionations of gastric juice urea provide new insights into the actual state of the infection of PUD or NUD. We also provide evidence of the unusual 13 C and 18 O-isotopic fractionations of breath CO 2 that are distinctively altered in individuals with PUD encompassing both gastric and duodenal ulcers as well as with NUD by the enzymatic activity of H. pylori in the gastric niche without oral administration of any 13 C-enriched external urea. This deepens our understanding of the UBT exploiting the natural 13 C and 18 O-gastric juice urea in the pathogenesis of H. pylori infection, reveals the actual disease state of PUD or NUD and thus offers novel opportunities for a simple, robust, cost-effective and non-toxic global strategy devoid of any 13 C-enriched urea for treating these common diseases by a single breath test. Graphical Abstract Urea breath test without any external urea.

    Gastric ulcers (GUs) are a common type of peptic ulcer. Alcohol overdose is one of the main causes of GU, which is difficult to prevent. Although the protective effect of butyrate on inflammation-related diseases is well understood, its effect on GUs has not been reported. We investigated the protective effects of butyrate against ethanol-induced lesions to the gastric mucosa in mice and the underlying mechanisms. BALB/c mice were orally pretreated with butyrate for 30min prior to the establishment of the GU model by challenge with absolute ethanol. Ethanol administration produced apparent mucosal injuries with morphological and histological damage, whereas butyrate pretreatment reduced the gastric mucosal injuries in a dose-dependent manner. Butyrate pretreatment also significantly ameliorated contents of malondialdehyde (MDA) and carbonyl proteins, and decreased levels of IL-1β, TNF-α and IL-6. The Western blot results consistently demonstrated that butyrate pretreatment attenuated the phosphorylation of NF-κB p65, p38 MAPK and ERKs in the gastric tissues. Additionally, gastric wall mucus (GWM), a parameter reflecting mucosal defense, was clearly increased by butyrate pretreatment. Butyrate pretreatment protects the gastric mucosa against ethanol-induced lesions by strengthening the mucosal defense and anti-oxidant and anti-inflammatory activities. As a necessary substance for the body, butyrate may be applied to the prevention and treatment of GUs. Copyright © 2015 Elsevier B.V. All rights reserved.

    Gastrofiberscopy as well as roentgenologic examination of stomach, is now considered to be one of the indispensable diagnostic method of gastric disease. In general it is agreed that the roentgenologic examination is convenient for observation of shape, contour, motor function and gross lesion of stomach white gastrofiberscopy is especially valuable in detection of mucosal changes or small lesions of stomach. For evaluation of gastrofiberscopy in the diagnosis of various gastric diseases, the diagnostic accuracy of gastrofiberscopy was studied in 964 cases who underwent the fiberscopic examination in SNUH during the period from March 1, 1968 till April 30, 1971. The following results were obtained. 1. Each fiberscopic diagnosis in the 964 cases was classified as follows: normal stomach 414 cases (42.9%), gastritis 74 cases (7.7%), gastric ulcer 134 cases (13.9%), healed ulcer 14 cases (1.5%), benign pyloric stenosis 15 cases (1.6%), suspicious duodenal ulcer 23 cases (2.4%), gastric polyp 6 cases (0.6%), leiomyoma 1 case (0.1%), bezoar 2 cases (0.2%), xanthoma 1 case (0.1%), gastric carcinoma 237 case (24.6%), extrinstic mass 1 case (0.1%), post-operative condition 9 cases (0.9%), unsatisfactory examination 31 cases (3.2%), indeterminate diagnosis 2 cases (0.2%). 2. In various gastric diseases, the coincidence rate of diagnosis between fiberscopic and roentgenologic examination was studied and the obtained results are as follows: in normal stomach 72.9% (302/414), gastric ulcer 69.4% (93/134), healed ulcer 42.9% (6/14), benign pyloric stenosis 86.7% (13/15), duodenal ulcer 100.0% (23/23), gastric polyp 66.7% (4/6), gastric carcinoma 87.8% (208/237), post operative condition 66.7% (6/9). The overall result shows that the diagnostic coincidence between the two methods was observed in 67.7% of the cases (653/964). 3. The diagnostic accuracy of fiberscopic examination was 85.7% (24/28) in the diagnosis of gastric ulcer, 75.0% (6/8) in the diagnosis of benign pyloric

    Full Text Available The elderly population has experienced increased life expectancy as well as the increased incidence of gastric ulcers. The peels of fruits from Citrus aurantium L., popularly known in Brazil as orange bitter, are commonly used asatea form for the treatment of gastrointestinal tract disorders, such as ulcer and gastritis. We evaluated the healing effects of essential oil from the peels of Citrus aurantium fruits (OEC on gastric ulcers in middle-aged rats. We examined the effects of a 14-day chronic OEC treatment on gastric mucosa in middle-aged male Wistar rats that were given acetic-acid-induced gastric lesions by morphometric and immunohistological analyses. Oral OEC treatment significantly reduced the lesion area (76% within the gastric mucosa and significantly increased (P<.05 the height of regenerated mucosa (59% when compared to the negative control group. Immunohistochemical analysis of the molecular markers such as COX-2, HSP-70, VEGF, and PCNA in the gastric mucosa confirmed that OEC treatment induced healing effects by increasing the number of new blood vessels and by augmenting gastric mucus in the mucosa glands. These results suggest that the oil from Citrus aurantium effectively heals gastric ulcers in middle-aged animals; however, safe use of OEC demands special care and precautions.

    Radioimmunoassay of gastrin level in the blood was performed in 20 controls, 12 patients with duodenal ulcer, 13 patients with atrophic gastritis and 14 patients with Addison-Biermer's disease. Gastrin level in the serum of the patients with duodenal ulcer did not differ significantly from that of controls. In atrophic gastritis and particularly in Addison-Biermer's disease gastrin level was found to be several times higher. This is probably a result of chronic gastrin secretion stimulation which is normally inhibited by gastric juice. (author)

    Full Text Available Extract of Echinops persicus is traditionally used for a long time in Iran for treatment of cough and constipation. This extract is produced by activity of bug (Situphilus spp. on the plant. We documented its anti-tussive effect in rats in our previous study.The aim of this study was to assess the anti-ulcer effect of Echinops persicus in an animal model. In this study we evaluated anti-ulcer effect of Echinops persicus by Shay's method in rats. In 3 groups of rats, pylorus was ligatured under anesthesia. The rats were euthanized after 19 hours later and number and level of ulcer in stomach was measured. In group 2 the extract was orally administered 45 minutes before pyloric ligature, and in group 3, it was administered intraperitoneally 20 minutes before pyloric ligature. The number of ulcers in stomach was significantly low in group 2 (P = 0.01 and 3 (P = 0.037 in comparison with group 1. The level of ulcer was significantly decreased in group 2 (P = 0.047 with comparison to group 1. We conclude that, Echinops extract can exhibit potentially cytoprotective and anti-ulcer activity.

    Yttrium-90 microsphere radioembolization ((90)Y MRE) is a therapy for liver malignancies by permanently implanting (90)Y-containing microspheres into tumors via hepatic artery. The etiology of persistent gastric ulcerations in patients presenting months after treatment remains unclear. Three patients who presented with gastric ulceration 4 to 13 months after (90)Y MRE were examined by esophagogastroduodenoscopy and biopsies. Pathological examinations showed multiple (90)Y microspheres scattered within the lamina propria and submucosa. Most of the microspheres were distributed in a linear fashion, consistent with an intravascular location; however, the vascular lumen and endothelial cells were not present. The microspheres were surrounded by fibrotic tissue infiltrated by chronic inflammatory cells and rare neutrophils. Epithelial granulation without pititis and miniaturized glands with intervening fibrosis were noted, compatible with chronic ischemic changes. These findings suggest that the persistent gastric ulceration is a result of localized ischemic injury in response to (90)Y MRE-induced vascular damage. Copyright © 2015 Elsevier Inc.

Because of complete gastric retention the acid gastric secretions provoked by cysteamine probably accumulate in the stomach during the first 4 h after cysteamine administration, and because of the absence of peristalsis they are not mixed with gastric contents...... and measurements of gastric acid secretions after cysteamine. Vagotomy augmented the inhibitory effect of cysteamine on gastric motility. The relaxation was even more pronounced, and contrast medium was not discharged from the stomach within 24 h. In these rats cysteamine induced ulcerations in the stomach....... gastric empyting was due to a pronounced relaxation of the stomach and a complete blocking of gastric peristalsis. These effects have their maximum within the first 4 h after administration of cysteamine. Thereafter peristalsis and gastric empyting slowly return. In controls contrast medium administered...

    Peptic ulcer disease including both gastric and duodenal ulcer form a substantial part of patients seeking surgical opinion world-wide. The concept of acid in peptic ulcer disease, which was the basis of treatment of peptic ulcer was revolutionized by the discovery of H2-receptor antagonists, that led to the principle of acid suppression therapy for duodenal ulcer which followed decades of preference for surgical interventions in the form of gastric resections, vagotomy etc., After the discovery of Helicobacter pylori organism as the causative factor a triple drug regime was identified to treat peptic disease which was further modified to sequential therapy to avoid antibiotic resistance. This recognition has not concluded the chapter on peptic ulcers. The management of ulcer disease and its complications remain a surgical challenge. All the materials for this review have been accessed from various internet search engines. The references have been narrowed down to 34 by excluding cross references, duplicated citations, pediatric studies, case reports, iatrogenic and malignant perforations and including microbiological, immunohistochemistry references and studies with more than a sample size of ten. Case control, cohort studies, prospective/retrospective, metaanalytical studies were preferred in that order. This article attempts to take an overview of all aspects of the management of peptic ulcer.

    The Japanese Society of Gastroenterology (JSGE) revised the evidence-based clinical practice guidelines for peptic ulcer disease in 2014 and has created an English version. The revised guidelines consist of seven items: bleeding gastric and duodenal ulcers, Helicobacter pylori (H. pylori) eradication therapy, non-eradication therapy, drug-induced ulcer, non-H. pylori, non-nonsteroidal anti-inflammatory drug (NSAID) ulcer, surgical treatment, and conservative therapy for perforation and stenosis. Ninety clinical questions (CQs) were developed, and a literature search was performed for the CQs using the Medline, Cochrane, and Igaku Chuo Zasshi databases between 1983 and June 2012. The guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. Therapy is initially provided for ulcer complications. Perforation or stenosis is treated with surgery or conservatively. Ulcer bleeding is first treated by endoscopic hemostasis. If it fails, surgery or interventional radiology is chosen. Second, medical therapy is provided. In cases of NSAID-related ulcers, use of NSAIDs is stopped, and anti-ulcer therapy is provided. If NSAID use must continue, the ulcer is treated with a proton pump inhibitor (PPI) or prostaglandin analog. In cases with no NSAID use, H. pylori-positive patients receive eradication and anti-ulcer therapy. If first-line eradication therapy fails, second-line therapy is given. In cases of non-H. pylori, non-NSAID ulcers or H. pylori-positive patients with no indication for eradication therapy, non-eradication therapy is provided. The first choice is PPI therapy, and the second choice is histamine 2-receptor antagonist therapy. After initial therapy, maintenance therapy is provided to prevent ulcer relapse.

    Full Text Available Abdominal Tuberculosis (TB most commonly affects ileo-caecal region. Isolated stomach involvement by TB, without pulmonary infection is rare. Clinical presentation of Stomach TB may be non-specific, radiological findings non-contributory and superficial endoscopic biopsies may not be able to settle the diagnosis. Many cases are diagnosed only after histopathological examination of surgical specimens. High degree of suspicion is needed for early diagnosis of gastric tuberculosis, if unnecessary surgical interventions are to be avoided. A young patient who was being treated as a case of chronic peptic ulcer for one year was referred for treatment of gastric outlet obstruction. Histopathological examination of gastrectomy specimen of the patient showed multiple caseating granulomas characteristic of tuberculosis and presence of acid-fast bacilli on Fite-Faraco staining, with no evidence of tuberculosis at pulmonary or other body sites. This case of isolated gastric TB is reported for its rarity.

    Full Text Available Abstract Background Anastomotic or marginal ulcers occur in 0.6 to 16% of patients after laparoscopic Roux-en-Y-Gastric Bypass. Initial therapy aims at eliminating known risk factors including smoking, Helicobacter pylori infection, use of non-steroidal anti-inflammatory drugs and inhibition of gastric acid secretion. While this approach is successful in 68 to 88% of the cases, up to one third of patients need a subsequent surgical revision. However, marginal ulcers still recur in up to 10% of cases after revisional surgery, thus constituting a serious challenge for bariatric surgeons. Case presentation We herein report a case of an insidious marginal ulcer refractory to both medical therapy with high-dosed proton pump inhibitors and sucralfate as well as surgical therapy consisting of the lengthening of a short alimentary limb and later resection of the gastroenterostomy and construction of a new tension-free anastomosis. Only after gastrectomy by laparoscopic en-bloc resection of the gastrojejunostomy, the gastric pouch and resection of the gastric remnant with reconstruction by esophagojejunostomy the patient remained free of symptoms. Conclusion By laparoscopic resection of the entire gastric pouch and the gastric remnant the risk to leave a suboptimally vascularised or even ischemic pouch in situ was avoided. The esophagojejunostomy was then created in healthy, good vascularised tissue. In our case this novel approach was effective in the management of a refractory anastomotic ulcer and might represent a rescue option when simple revision of the gastrojejunostomy fails.

    Sea buckthorn berries (Hippophae rhamnoides) are rich in vitamin C and E, carotenoids, flavonoids, fatty acids, plant sterols, lignans, and minerals. A feed supplement containing sea buckthorn berries might have efficacy in treatment and prevention of gastric ulcers in horses. To test the efficacy of a commercially available formulation of sea buckthorn berries and pulp (SeaBuck SBT Gastro-Plus) for treatment and prevention of gastric ulcers in stall-confined horses. Eight Thoroughbred and Thoroughbred-cross horses (3-10 years of age, 5 geldings and 3 mares, 380-600 kg body weight). This study was a 2-period crossover in which all horses received no treatment (untreated controls; n = 8) and treatment (SeaBuckSBT Gastro-Plus, 4 ounces [35.6 g berries and pulp], twice daily; n = 8) mixed with a pelleted complete feed (18% crude fiber; 9% starch; 14% crude protein). Horses were treated for 4 weeks followed by a 1-week (d28-d35) alternating feed-deprivation period to induce or worsen existing ulcers. Gastroscopic examinations were performed on days 0, 28, and 35. Gastric juice pH was measured and gastric ulcer number and severity scores were assigned by a masked investigator. Mean nonglandular gastric ulcer scores significantly (P prevention of naturally occurring nonglandular ulcers in horses; however, glandular ulcer scores were significantly lower in SBT-treated horses after feed deprivation. Thus, SBT might have efficacy in prevention of glandular ulcers in horses housed in stalls and undergoing intermittent feeding.

    Three sesquiterpene lactones [two germacranolides (micranthin and sintenin) and one guaianolide (4β,10α-dihydroxy-5β,7β,8βH-guaia-1,11(13)dien-12,8α-olide)] and four derivatives of 3-methoxy flavones (santin, quercetagetin-3,6,3'-trimethyl ether, quercetagetin-3,6-dimethyl ether, and 5,7 dihydroxy 3,3',4'-trimethoxy flavone) were isolated from the ethyl acetate extract (EAE) of the aerial parts of Achillea biebersteinii Afan. (Asteraceae). Evaluation of protective and therapeutic effects of EAE against ethanol-induced gastric ulcer in rats was carried. Antiulcer activity evaluation was done through measuring ulcer indices, stomach acidity, gastric volume and lesion counts. Oxidative stress markers; malondialdehyde, glutathione and superoxide dismutase were also estimated. The work was extended to determine the histopathological assessment of the stomach. Gastric ulcer exhibited a significant elevation of the ulcer index and oxidative stress markers. The extract attenuated these increments and recorded protective and therapeutic effects against gastric ulcer. Hyperglycaemia increases the mucosal susceptibility to ulcerogenic stimuli and predisposes gastric ulceration. In vitro α-amylase inhibitory assay was applied to evaluate the post prandial antihyperglycaemia activity. The result showing that the EAE has the ability to reduce starch-induced postprandial glycaemic excursions by virtue of potent intestinal α-amylase inhibitory activity. These findings demonstrated the remarkable potential of A. biebersteinii as valuable source of antiulcer agent with post prandial hyperglycaemia lowering effect.

    Dramatic changes in the prevalence and pattern of gastrointestinal disease has taken place in Asia in recent years. To compare the prevalence of duodenal (DU) and gastric ulcers (GU), erosive oesophagitis (EO), gastric cancer (GCA) and oesophageal cancer (OCA) and Helicobacter pylori infection over a 10-year interval of time in a multiracial South-East Asian population. Endoscopy records of first time gastroscopy in the University of Malaya Medical Centre, Kuala Lumpur, Malaysia were reviewed for 1989/1990 and 1999/2000. In the period of 1989-1990, 3252 records and in 1999-2000, 4615 records were analysed. Both DU (21.1-9.5%) and GU (11.9-9.4%) had decreased significantly (P < 0.001). EO had increased significantly from 2.0% to 8.4% (P < 0.001). Both GCA and OCA had declined in the 10-year interval. Helicobacter pylori prevalence had decreased from 51.7% to 30.3% (P < 0.001).The decrease in DU and GU was seen in all racial groups. The increase in EO was most marked in Indians and the decrease in GCA in Chinese. The proportion of H. pylori-associated DU and GU had also decreased with time. Peptic ulcers and H. pylori infection had declined over a 10-year period of time and showed an opposing time trend with EO, which had increased dramatically. Both GCA and OCA had declined in prevalence.

    Full Text Available Aims & Objectives: Ocimum sanctum L. popularly known as Tulsi is a medicinal plant that has been used for curing various diseases since ages. In the present study we used leaf extract of Ocimum sanctum for its anti-ulcer property by inducing stress ulcers on rats. Materials and Method: Albino rats were randomly allocated to different experimental groups and aqueous leaf extract of Ocimum sanctum was given for 7 days. Stress ulcers were induced by restraint and ethanol administered methods and results were compared with standard drug ranitidine. After that animal was sacrificed and stomach was dissected out and stomachs were observed for the ulceration with the help of magnifying lens and studied its external, internal surface and ulcer index was evaluated according to the severity of ulcers. The stomach were stored and fixed in 5% formalin and studied for histopathological changes. Results: The ulcer index was high in control group. Animal pretreated with Ocimum sanctum at the dose 100 & 200 mg/kg showed few signs of mucosal injury and the percentage of damage were less compared to control group. Conclusion: In the present study pretreatment with Ocimum sanctum at dose 100-200 mg/kg caused a significant anti-ulcer effect in rats in comparison with control group and its effect is comparable to the standard drug ranitidine, as evidenced by the reduction in the ulcer scores.

    Most patients with peptic ulcer disease are currently treated with proton pump inhibitors or histamine H(2) receptor antagonists. The long-term use of these compounds has been associated with two potential problems. Firstly, proton pump inhibitors may induce enterochromaffin-like (ECL) cell hyperplasia. Secondly, ulcers may relapse despite maintenance therapy with histamine H(2) antagonists. This has been the rationale for the development of new antisecretory agents, including antagonists against gastrin and gastrin releasing peptide (GRP), as well as ligands to histamine H(3) receptors. Several potent, high affinity cholecystokinin (CCK)-2 receptor antagonists have recently been identified such as L-365260, YM-022, RP-73870, S-0509, spiroglumide and itriglumide (CR-2945). Current data suggest that they all have antisecretory and anti-ulcer effects. In addition to reducing acid production, CCK-2 receptor antagonists may possibly also accelerate gastric emptying, a combination of functions which could potentially be beneficial in patients with functional dyspepsia. Receptors for bombesin and its mammalian counterpart GRP have been localised in the brain, spinal cord and enteric nerve fibres of the gut as well as on secretory cells and smooth muscle cells of the intestinal tract. Current data clearly indicate that endogenous GRP is involved in the regulation of basal and postprandial acid secretion. However, at this stage it is not clear whether GRP agonists or GRP antagonists can be developed into useful drugs. The peptide has a wide range of biological effects and it is likely that analogues of GRP or antagonists of the peptide affect not only gastric acid secretion but also induce considerable side effects. Histamine plays a central role in the stimulation of acid secretion. After their detection in the brain, H(3) receptors have been identified in a variety of tissues including perivascular nerve terminals, enteric ganglia of the ileum and lung, and ECL cells

    Full Text Available Objective: To assess and compare the risk factors in patients with benign gastric and duodenal ulcers and to correlate the prevalence of Helicobacter pylori (H. pylori infection in benign peptic ulcer disease. Methods: A total of 30 consecutive patients with peptic ulcer disease were included in this study after upper gastrointestinal endoscopy. Their clinical profile and endoscopic findings were noted. Antral biopsies were subjected to histopathological examination and urease test for detection of H. pylori. Results were correlated. The study was cleared by the Institute Research Council and the Ethics committee. Results: The male: female ratio was 11:4. Overall, H. pylori infection was prevalent in 93.3% of the patients. Patients who took spicy food had a significantly higher rate of H. pylori positivity (P=0.04. Smoking, alcohol intake and NSAIDs did not affect H. pylori status in patients. There was no significant association between the site of the ulcer and H. pylori infection. Conclusions: Based on our observations we conclude that prevalence of H. pylori infection is similar in duodenal and gastric ulcers and intake of spicy food is a significant risk factor.

    A roentgenological and endoscopical study is presented of the stomach and duodenum in 66 patients during remission and in 22 patients during exacerbation of ulcer disease from 6 months up to 5 years after organsaving operations using vagotomy. In the majority of patients the stomach was characterized by a large gas bubble, cascade-like torsion, deformation of the antral portion and duodenal bulb. In some patients thickenings of the gastric antral mucosa were noted. An endoscopically confirmed ulcer was revealed roentgenologically only in 50% of patients

    Gastrointestinal endoscopy is a standard diagnostic tool for gastrointestinal ulcers and cancer. In this study, we have developed recombinant human epidermal growth factor-containing ulcer-coating polymeric sol-gel for endoscopic application. Chitosan and pluronic F127 were employed for their thermoresponsive and bioadhesive properties. At temperatures below 21, polymeric sol-gel remains liquid during endoscopic application and transforms to gel at body temperature after application on ulcers. In an in vitro cellular wounding assay, recombinant human epidermal growth factor sol-gel significantly enhanced the cell migration and decreased the wounding area (68%) compared to nontreated, recombinant human epidermal growth factor solution, and sol-gel without recombinant human epidermal growth factor (42, 49, and 32 % decreased at day 1). The in vivo ulcer-healing study was performed in an acetic acid-induced gastric ulcer rat model and proved that our recombinant human epidermal growth factor endoscopic sol-gel facilitated the ulcer-healing process more efficiently than the other treatments. Ulcer sizes in the recombinant human epidermal growth factor sol-gel group were decreased 2.9- and 2.1-fold compared with those in the nontreated group on days 1 and 3 after ulceration, respectively. The mucosal thickness in the recombinant human epidermal growth factor sol-gel group was significantly increased compared to that in the nontreated group (3.2- and 6.9-fold on days 1 and 3 after ulceration, respectively). In a gastric retention study, recombinant human epidermal growth factor sol-gel stayed on the gastric mucosa more than 2 h after application. The present study suggests that recombinant human epidermal growth factor sol-gel is a prospective candidate for treating gastric ulcers via endoscopic application.

    Vascular endothelial growth factor (VEGF) is one of the most important growth factors for metastatic tumors. To clarify the role of VEGF-A and C in patients with peptic ulcer disease (PUD) or gastric cancer (GC), we evaluated the expression levels of these two molecules. We also analyzed the effect of Helicobacter pylori infection on VEGF-A and C expression levels. PATIENTS WITH DYSPEPSIA WHO NEEDED DIAGNOSTIC ENDOSCOPY WERE SELECTED AND DIVIDED INTO THREE GROUPS: non-ulcer dyspepsia (NUD), PUD, and GC, according to their endoscopic and histopathological results. Fifty-two patients with NUD, 50 with PUD, and 38 with GC were enrolled in this study. H. pylori infection was diagnosed by the rapid urease test. After RNA extraction and synthesis of cDNA, the expression levels of VEGF-A and C were determined by quantitative reverse transcriptase polymerase chain reaction. The VEGF-C expression level in the PUD and GC groups was significantly higher than that in the NUD group. Moreover, the VEGF-A expression level in the PUD and GC groups was higher than in the NUD group, although the differences were not statistically significant. Significant positive correlations were also observed between the expression levels of these two molecules in the PUD and GC groups. In addition, the expression levels of these two molecules were higher in H. pylori positive patients with PUD or GC than in H. pylori negative patients of the same groups; however, these differences did not reach statistical significance. Up-regulation of VEGF-C expression during gastric mucosal inflammation may play a role in the development of peptic ulcers or GC.

    In the present study, the gastroprotective effects of arctigenin of Fructus Arctii were evaluated and the possible underlying mechanisms of action were elucidated. Arctigenin (high-performance liquid chromatography purity, >99.0%) was isolated and purified from the seeds of Arctium lappa L. The anti-ulcerogenic activity of arctigenin against ulcers induced by absolute ethanol and acetic acid was evaluated in a Sprague-Dawley rat model. In addition, the antioxidant activity was assessed by measuring malondialdehyde (MDA) levels in an ethanol-induced model and the anti-inflammatory effects were assessed by measuring five factors in an acetic acid-induced model. In the ethanol-induced model, arctigenin inhibited gastric lesions in a dose-dependent manner, by 53.04, 53.91 and 64.43% at doses of 0.05, 0.15 and 0.45 mg/kg, respectively. In addition, arctigenin reduced MDA (Parctigenin (0.05, 0.15 and 0.45 mg/kg; Parctigenin group compared with the vehicle group. Thus, the current study indicated that arctigenin exerted anti-ulcer activity, which may be associated with its reduction in oxidative and inflammatory damage. All the results indicate that arctigenin may be used as an effective therapeutic agent to prevent gastric ulcers.

    45 patients with uncomplicated duodenal ulcer who did not respond to cimetidine underwent elective proximal gastric vagotomy (PGV). 39 of these, who had received cimetidine for an average of 5.2 months before surgery, were followed up for 20-67 months postoperatively. 18(46%) of them were classified as grade IV (ie, failures) according to a modified Visick scale--17 (44%) had a recurrent peptic ulcer. Augmented histamine tests done in 17 patients showed an expected reduction of peak acid output, so maintenance of stomach acidity was unlikely to be a cause of failure of the operation. The presence of mental and social problems preoperatively was associated with a postoperative Visick grade IV. Despite repeated medical therapy, and reoperation in 6 patients, 10(26%) patients still had severe pain and/or dumping at follow up. Proximal gastric vagotomy cannot be advocated in patients with uncomplicated duodenal ulcer resistant to cimetidine, and an alternative treatment is needed for these patients.

    Full Text Available Background: In various studies, Cydonia oblonga Miller (quince has been reported to have many properties such as antioxidant and anti-ulcerative effects. This study has aimed to investigate the protective effects of quince aqueous extract (QAE and quince hydroalcoholic extract (QHE on gastric ulcer caused by indomethacin and the relevant macroscopic, histopathology, and biochemical factors in rats. Methods: Ten groups of male Wistar rats, six in each, were used in this study. These groups included: normal (distilled water, control (distilled water + indomethacin, reference (ranitidine or sucralfate + indomethacin, and test groups (QAE or QHE + indomethacin treated with three increasing doses (200, 500, and 800 mg/kg. Extracts and drugs were given orally to rats 1 h before injecting the indomethacin (25 mg/kg, intraperitoneally. Six hours later, the abdomen of rats was exposed, its pylorus was legated, gastric acid content was extracted, and its pH and the amount of pepsin secreted were measured by Anson method. Then, histopathology indices, ulcer area, ulcer index, and myeloperoxidase (MPO activity were measured in gastric mucus. Results: Both extracts of quince were effective to reduce the acidity of stomach and pepsin activity. Compared to control group, the average of enzyme activity of MPO was significantly declined in all treated groups. Control group had the highest level of gastric ulcer indices including severity, area, and index while the evaluated parameters had decreased in all extract treated groups although it seems that QAE was somewhat more effective. Conclusions: Protective effect of QAE and QHE on gastric ulcer was done by undermining offensive factors including decreasing the secretion of gastric acid and pepsin activity and by strengthening the protective factors of gastric mucus including antioxidant capacity.

    Convolvulus pluricaulis is an indigenous plant commonly mentioned in Ayurveda, an ancient system of Indian medicine, as a rasayana which is mainly advocated for use in rejuvenation therapy. The present study was conducted to evaluate the potential anti-ulcerogenic effect of juice of fresh whole plants of C. pluricaulis (CPJ) against various experimental gastric ulcer models induced by ethanol, aspirin, 2 hr cold restraint stress and 4 hr pyloric ligation in rats. The drug was given orally twice daily for five days in the doses of 375 and 750 mg/kg body weight. CPJ showed anti-ulcerogenic effect at both doses in all the experimental gastric ulcer models and was comparable to the reference drug sucralfate (250 mg/kg). Gastric juice secretion and mucosal studies were undertaken to find out the possible mechanism of action of antiulcer effect by studying its effects both on offensive and defensive mucosal factors. The antiulcerogenic effect of CPJ was found to be due to augmentation of mucosal defensive factors like mucin secretion, lifespan of mucosal cells and glycoprotiens rather than on the offensive factors like acid-pepsin.

    Epidemiologic studies have provided conflicting data regarding an association between Helicobacter pylori infection and iron deficiency anemia (IDA) in humans. Here, a Mongolian gerbil model was used to investigate a potential role of H. pylori infection, as well as a possible role of diet, in H. pylori-associated IDA. Mongolian gerbils (either H. pylori infected or uninfected) received a normal diet or one of three diets associated with increased H. pylori virulence: high-salt, low-iron, or a combination of a high-salt and low-iron diet. In an analysis of all infected animals compared to uninfected animals (independent of diet), H. pylori-infected gerbils had significantly lower hemoglobin values than their uninfected counterparts at 16 weeks postinfection (P Anemia was associated with the presence of gastric ulceration but not gastric cancer. Infected gerbils consuming diets with a high salt content developed gastric ulcers significantly more frequently than gerbils consuming a normal-salt diet, and the lowest hemoglobin levels were in infected gerbils consuming a high-salt/low-iron diet. These data indicate that H. pylori infection can cause IDA and that the composition of the diet influences the incidence and severity of H. pylori-induced IDA. PMID:27620719

    Bilobalide (BI) has been widely known as a unique constituent extracted from Ginkgo biloba. The aim of the current study was to reveal the potential efficacy as well as the underlying mechanism of the action of BI on ethanol-induced lesion in gastric mucosa in vivo/vitro. Ethanol (0.2ml/kg) was applied to induce gastric ulcer mice model. Our results indicated that treatment with BI markedly decreased the levels of interleukin-6 (IL-6), IL-1β and tumor necrosis factor-α (TNF-α) in vivo. Additionally, BI intervation exhibited elevated myeloperoxidase (MPO) level in stomach, increased superoxide dismutase (SOD) activity and decreased malonaldehyde (MDA) content in serum and stomach when compared with those of the model group. It could be also observed that inhibited MAPK/NF-κB pathway expressions occurred after BI treatment both in vivo and in vitro. Taken together, BI exerted a gastro-protective effect against gastric ulceration, which was presumed to be associated with MAPK/NF-κB pathway. Copyright © 2016. Published by Elsevier Masson SAS.

    Peptic ulcer disease refers to pathological lesions and ulcers of any portion of gastrointestinal tract exposed to acid activated pepsin. Gastric ulcer refers to ulcer in the stomach where as duodenal ulcer is a ulcer found in duodenum of small intestine. Helicobacter pylori infection, a spiral shaped type of bacteria, is present in more than 90% of the patients with intestinal ulcers and more than 80% of patients with stomach ulcers. Helicobacter pylori weaken the protective mucous coating o...

    Background and aim: H. pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) remain the major causes of peptic ulcer disease. Nevertheless, non- H. pylori non-NSAIDs peptic ulcers or idiopathic peptic ulcer disease (IPUD) constitute a growing problem associated with many complications. Gastric cancer and gastrointestinal stromal tumor (GIST) have also been reported as a cause of IPUD. This study was aimed to investigate prevalence and clinical characteristics of IPUD in Thailand. Materials and Methods: Clinical information, histological features, endoscopic findings, history of H. pylori status and NSAIDs usage were collected for patients diagnosed with PUD in Thammasat University Hospital during January 2003 – December 2013. Results: Total of 1,310 patients was diagnosed with PUD in our institution during the study period, of which 71 (5.4%) had a definitive diagnosis of IPUD (45 men and 26 women, mean age of 59±16.5 years). Common locations were gastric antrum (43.7%), duodenum (25.3%) and gastric body (12.7%). Common causes of IPUD were idiopathic (43.7%) and alcohol consumption (39.4%). Gastric cancer and GIST were also demonstrated in 1(1.4%) and 1(1.4%) respectively. Major complications were upper GI bleeding (73.2%) and peptic perforation (2.8%). Recurrent upper GI bleeding was detected in 23.9%. Interestingly, male patients aged<50 years with alcohol related peptic ulcer were significantly more common than female patients aged ≥ 50 years (57.8% vs 7.7%;P-value= 0.00002, OR= 16.4, 95%CI= 3.5-78 and 68.4% vs 28.9%); P-value= 0.002, OR= 5.3, 95% CI= 1.7-16.7). Conclusion: Common causes of IPUD in Thailand are idiopathic followed by alcohol consumption and steroid usage. Gastric cancer and GIST are also possible causes of IPUD. These particular ulcers had a high likelihood of developing severe complications. Appropriate screening and high level of suspicion of fatal causes eg. gastric cancer and GIST should be appropriate ways to reduce complications

    The authors have analyzed the role of the thin contour in radiodiagnisis of various diseases of the gastric mucosa. Altogether 140 patients with various gastric diseases were investigated. Using X-ray examination of the stomach based on the common 2-phase method, thin contour images were obtained in 80 % of the cases. The results of the investigation have revealed direct correlation between the type of the thin contour and a morphological picture of the gastric mucosa in chronic gastritis. Early stomach cancer was characterized by the local absence or rearrangement of a usual pattern of the thin contour on stomach radiograms. It was difficult to defect single erosions or polyps with a diameter under 5 mm against a background of the gastric mucosa thin contour. Good visualization of stomach areolae, particularly those of a rough nodular type in the proximal part of the stomach was suggestive of an ulcerative lesion

    Objective: The relationship between gastroesophageal reflux disease (GERD) and gastric emptying rate was investigated. Results of endoscopy, 24-hour esophageal pH monitoring were also evaluated. Methods: 15 patients were evaluated with endoscopy, pH monitoring and radionuclide gastric emptying. The results were compared with that of 17 control subjects. Correlations of gastric emptying rate and esophagitis, 24-hour pH monitoring between GERD patients and control subjects were also analyzed. Results: Liquid gastric emptying rate of GERD patients was significantly lower than that of control subjects at 15 and 30 min (P 0.05), but there exhibited a linear correlation between 50% solid emptying time and esophagus pH total score (r=0.643, P<0.05). Conclusions: The results indicate a delayed liquid and solid gastric emptying in GERD patients. There is a linear correlation between 50% solid emptying time and esophagus pH total score. Delayed gastric emptying may be an important factor in the pathogenesis of GERD

    Peptic ulcer perforation is a common cause of emergency admission and surgery. This is the first study that documents the presentation and outcome of management in Irrua, Nigeria. This is a prospective study of all patients operated on for perforated peptic ulcer between April 1, 2010, and March 31, 2015. A structured questionnaire containing patients' demographics, operation findings, and outcome was filled upon discharge or death. There were 104 patients. 81 males and 23 females (M : F = 3.5 : 1). The age range was between 17 years and 95 years. The mean age was 48.99 years ± SD 16.1 years. The ratio of gastric to duodenal perforation was 1.88 : 1. Perforation was the first sign of peptic ulcer disease in 62 (59.6%). Pneumoperitoneum was detectable with plain radiographs in 95 (91%) patients. 72 (69.2%) had Graham's Omentopexy. Death rate was 17.3%. We note that gastric perforation is a far commoner disease in our environment. Perforation is often the first sign of peptic ulcer disease. We identify fasting amongst Christians as a risk factor for perforation.

    Long-term nonsteroidal anti-inflammatory drugs (NSAIDs) therapy has been associated with several adverse effects such as gastric ulceration and cardiovascular events. Among the molecular modifications strategies, the prodrug approach is a useful tool to discover new safe NSAIDs. The 1-(2,6-dichlorophenyl)indolin-2-one is a diclofenac prodrug which demonstrated relevant anti-inflammatory properties without gastro ulceration effect. In addition, the prodrug decreases PGE(2) levels, COX-2 expression and cellular influx into peritoneal cavity induced by carrageenan treatment. Preliminary pharmacokinetic studies have shown in vivo bioconversion of prodrug to diclofenac. This prodrug is a new nonulcerogenic NSAID useful to treat inflammatory events by long-term therapy.

    Nitric oxide (NO) plays an important role in regulation of central and peripheral circulation in normal state and during hemorrhagic stress. Because the impaired gastric mucosal blood flow is the major cause of gastroduodenal lesions including ulcer bleeding (UB), we study in this work the NO-ergic mechanism responsible for regulation of this blood flow. Our study is performed in rats with a model of stress-induced UB using laser Doppler flowmetry (LDF) that characterizes the rate of blood flow by measuring a Doppler shift of the laser beam scattered by the moving red blood cells. Numerical analysis of LDF-data is based on the discrete wavelet-transform (DWT) using Daubechies wavelets aiming to quantify influences of NO on the gastric microcirculation. We show that the stress-induced UB is associated with an increased level of NO in the gastric tissue and a stronger vascular sensitivity to pharmacological modulation of NO-production by L-NAME. We demonstrate that wavelet-based analyses of NO-dependent regulation of gastric microcirculation can provide an effective endoscopic diagnostics of a risk of UB.

    The adrenergic system plays an important role in regulation of central and peripheral circulation in normal state and during hemorrhage. Because the impaired gastric mucosal blood flow (GMBF) is the major cause of gastroduodenal lesions, including ulcer bleeding (UB), we studied the adrenergic mechanism responsible for regulation of GMBF in rats with a model of stress-induced UB (SUB) using the laser Doppler flowmetry (LDF). First, we examined the effect of adrenaline on GMBF in rats under normal state and during UB. In all healthy animals the submucosal adrenaline injection caused a decrease in local GMBF. During UB the submucosal injection of adrenaline was accompanied by less pronounced GMBF suppression in 30,3% rats with SUB vs. healthy ones. In 69,7% rats with SUB we observed the increase in local GMBF after submucosal injection of adrenaline. Second, we studied the sensitivity of gastric β2-adrenoreceptors and the activity of two factors which are involved in β2-adrenomediated vasorelaxation-KATP -channels and NO. The effects of submucosal injection of isoproterenol, ICI118551 and glybenclamide on GMBF as well as NO levels in gastric tissue were significantly elevated in rats with SUB vs. healthy rats. Thus, our results indicate that high activation of gastric β2-adrenoreceptors associated with the increased vascular KATP -channels activity and elevated NO production is the important adrenergic mechanism implicated in the pathogenesis of UB.

    Free radicals and oxidative stress play a central role in gastric injuries caused by ethanol (EtOH). Antioxidant strategies to counteract EtOH toxicity are highly desirable. Norbixin (NBIX) is a carotenoid with antioxidant potential largely used in the food industry. This study evaluated the NBIX effects in a model of gastric ulcer induced by EtOH in rats. Male Wistar rats received NBIX doses of 0, 10, and 25 mg/kg by gavage 1 h after EtOH administration (0 or 75% solution, 1 mL/200 g of animal). The animals were euthanized 1 h after the NBIX administration, and their stomachs were removed for macroscopic and histopathological analyses, quantification of nonprotein sulfhydryl (NPSH) groups, lipid peroxidation (LPO) levels, and catalase (CAT) activity determination. NBIX increased LPO in gastric mucosa and caused CAT inhibition and NPSH depletion in EtOH-treated animals. Results showed that NBIX did not protect gastric tissue against EtOH damage, and this could be associated to a prooxidant effect. © The Author(s) 2015.

    Proton pump inhibitors are effective for the treatment of gastric ulcers after endoscopic submucosal dissection (ESD). However, the most excellent therapy is controversial. Vonoprazan, an active potassium-competitive acid blocker, has a strong gastric acid secretion inhibitory effect, but its efficacy for the treatment of post-ESD gastric ulcers is unclear. Herein, we aimed to determine the healing effect of vonoprazan on post-ESD gastric ulcers. We carried out a prospective randomized controlled trial examining 92 patients who had undergone ESD for the treatment of gastric neoplasms between April 2015 and June 2016 at Machida Municipal Hospital. Patients were treated with 20 mg/day vonoprazan (V group) or 20 mg/day esomeprazole (E group) for 8 weeks. We evaluated the 8-week cure rate for artificial ulcers and any complications after ESD. A total of 80 patients (median age, 73.5 years; 71.3% male) were analyzed. Cure rate for the V group was significantly higher than that for the E group (94.9% [37/39] vs 78.0% [32/41], respectively; P = 0.049). In a multivariate analysis, only vonoprazan was correlated with ulcer healing (odds ratio = 6.33; 95% CI = 1.21-33.20; P = 0.029). Delayed bleeding was experienced only in the E group (7.3% [3/41]), but no significant difference compared with the V group was observed (P = 0.241). Vonoprazan was significantly superior to esomeprazole for the healing of post-ESD gastric ulcers and should be considered as a treatment of first choice. © 2017 Japan Gastroenterological Endoscopy Society.

    Full Text Available Human stomach is the only known natural habitat of Helicobacter pylori (Hp, a major bacterial pathogen that causes different gastroduodenal diseases. Despite this, the impact of Hp on the diversity and the composition of the gastric microbiota has been poorly studied. In this study, we have analyzed the culturable gastric microbiota of 215 Malaysian patients, including 131 Hp positive and 84 Hp negative individuals that were affected by different gastric diseases. Non-Hp bacteria isolated from biopsy samples were identified by matrix assisted laser desorption ionization-time of flight mass spectrometry based biotyping and 16SrRNA sequencing. The presence of Hp did not significantly modify the diversity of the gastric microbiota. However, correlation was observed between the isolation of Streptococci and peptic ulcer disease. In addition, as a first report, Burkholderia pseudomallei was also isolated from the gastric samples of the local population. This study suggested that there may be geographical variations in the diversity of the human gastric microbiome. Geographically linked diversity in the gastric microbiome and possible interactions between Hp and other bacterial species from stomach microbiota in pathogenesis are proposed for further investigations.

    Zinc has been reported to mediate cellular responses to injury by producing cytoprotection via the scavenging of reactive oxygen species. Anti-stress medications are generally anti-psychotic drugs and anti- depressants. Some Anti-psychotic drugs such as risperidone have been reported to possess anti-ulcer activity. Risperidone as an antipsychotic drug blocks several neurotransmitter systems including dopaminergic, adrenergic, histaminergic and serotonergic pathways. The study investigated the antiulcer activity of Zinc Chloride (ZnCl(2)) in combination with risperidone in male Wistar rats. The animals were divided into two groups of twenty animals each for ZnCl(2) and risperidone groups. Each group was further divided into four subgroups. ZnCl(2) was administered orally at 20mg/kg, 40mg/kg and 80mg/kg to a subgroup, while 80mg/kg of ZnCl(2) was administered in combination with risperidone (0.1mg/kg, 0.3mg/kg and 0.5mg/kg) orally once daily for 21 days. The controls were treated with distilled water. Ulcer was induced using indomethacin. Histology of the stomach tissues was prepared with PAS and H& E stains. Ulcer score and ulcer area were assessed using standard methods. Data were analysed using student t-test and Graphpad Prism 5. There were decreases in ulcer scores using the different doses of ZnCl, (20mg/kg, 40mg/kg and 80mg/kg). Also using the highest dose ZnCl(2) (80mg/ kg) and different doses of risperidone there were decreases in ulcer scores compared to the control. This effect of the risperidone showed a significant dose- dependent reduction. The effect ZnCl(2), and risperidone were also reflected in the ulcer area and in the histology. These findings suggest that ZnCl(2), enhances the gastroprotective activity ofrisperidone in indomethacin- induced gastric ulcer. However, more detailed studies are necessary to confirm the relevance of this finding and its implications in clinical settings.

    Full Text Available Gastric ulcers are a worldwide health problem and their poor healing is one of the most important causes for their recurrence. We have previously reported the remarkable gastroprotective and anti-Helicobacter pylori activities of the methanolic extract (CpMet of Cyrtocarpa procera bark. This work investigates, in a murine model, the CpMet gastroprotective mechanism and establishes its preclinical efficacy in the resolution of ethanol-induced gastric ulcers. The results showed that the gastroprotective activity of CpMet is mainly associated with endogenous NO and prostaglandins, followed by sulfhydryl groups and KATP channels. Furthermore, CpMet (300 mg/kg, twice a day orally administered during 20 consecutive days promoted an ulcer area reduction of 62.65% at the 20th day of the treatment. The effect was confirmed macroscopically by the alleviation of gastric mucosal erosions and microscopically by an increase in mucin content and a reduction in the inflammatory infiltration at the site of the ulcer. No clinical symptoms or signs of toxicity were observed in the treated animals. The results indicate the safety and efficacy of CpMet in promoting high quality of ulcer healing by different mechanisms, but mostly through cytoprotective and anti-inflammatory effects, making it a promising phytodrug for ulcer treatment.

    In the present study, the gastroprotective effects of arctigenin of Fructus Arctii were evaluated and the possible underlying mechanisms of action were elucidated. Arctigenin (high-performance liquid chromatography purity, >99.0%) was isolated and purified from the seeds of Arctium lappa L. The anti-ulcerogenic activity of arctigenin against ulcers induced by absolute ethanol and acetic acid was evaluated in a Sprague-Dawley rat model. In addition, the antioxidant activity was assessed by measuring malondialdehyde (MDA) levels in an ethanol-induced model and the anti-inflammatory effects were assessed by measuring five factors in an acetic acid-induced model. In the ethanol-induced model, arctigenin inhibited gastric lesions in a dose-dependent manner, by 53.04, 53.91 and 64.43% at doses of 0.05, 0.15 and 0.45 mg/kg, respectively. In addition, arctigenin reduced MDA (P<0.01) and increased superoxide dismutase (P<0.01) levels in serum when compared with the vehicle group. The lesion index induced by acetic acid was significantly inhibited by all doses of arctigenin (0.05, 0.15 and 0.45 mg/kg; P<0.01) in comparison to the vehicle group and in a dose-dependent manner. In addition, it was shown that the expression levels of tumor necrosis factor-α, interleukin-6 (IL-6), IL-10 and C-reactive protein were significantly decreased (P<0.05) in the arctigenin group compared with the vehicle group. Thus, the current study indicated that arctigenin exerted anti-ulcer activity, which may be associated with its reduction in oxidative and inflammatory damage. All the results indicate that arctigenin may be used as an effective therapeutic agent to prevent gastric ulcers. PMID:27882222

    Purpose: To evaluate the risk of coronary heart disease (CHD) and cerebrovascular disease after radiotherapy (RT) for peptic ulcer disease. Methods and materials: Peptic ulcer disease patients treated with RT (n = 1859) or by other means (n = 1860) at the University of Chicago Medical Center between 1936 and 1965, were followed through 1997. The observed numbers of cause-specific deaths were compared with the expected numbers from the general population rates. During RT, 5% of the heart was in the treatment field and the remainder of the heart mostly received scattered radiation. A volume-weighted cardiac dose was computed to describe the average tissue dose to the entire organ. We used Cox proportional hazards regression analysis to analyze the CHD and cerebrovascular disease risk associated with RT, adjusting for confounding factors. Results: Greater than expected CHD mortality was observed among the irradiated patients. The irradiated patients received volume-weighted cardiac doses ranging from 1.6 to 3.9 Gy and the portion of the heart directly in the field received doses of 7.6-18.4 Gy. The CHD risk increased with the cardiac dose (p trend = 0.01). The cerebrovascular disease risk was not associated with the surrogate carotid dose. Conclusion: The excess CHD risk in patients undergoing RT for peptic ulcer disease decades previously indicates the need for long-term follow-up for cardiovascular disease after chest RT

  20. Bidirectional crosstalk between stress-induced gastric ulcer and depression under chronic stress.

    Shuang Zhang

    Full Text Available Stress contributes to a variety of diseases and disorders such as depression and peptic ulcer. The present study aimed to investigate the correlation between stress ulcer and depression in pathogenesis and treatment by using chronic stress depression (CSD, chronic psychological stress ulcer (CPSU and water immersion restrain stress models in rats. Our data showed that the ulcer index of the animals after CSD exposure was significantly higher than that of controls. Depression-like behaviors were observed in rat after CPSU exposure. Fluoxetine hydrochloride significantly reduced the ulcer index of rats exposed to CPSU stress, while ranitidine inhibited depression-like behavior of the animals in CSD group. The ulcer index of rats administered with mifepristone after CPSU stress was markedly reduced compared to CPSU group, although there was no significant difference in the depression-like behavior between mifepristone-treated CSD group and naive controls. We also found that the rats exposed to CPSU or CSD stress displayed a lower level of corticosterone than naive controls, however, the acute stress (AS group showed an opposite result. Additionally, in order to study the relevance of H(2 receptors and depression, we treated the CSD group with cimetidine and famotidine respectively. The data showed that cimetidine inhibited depression-like behavior in CSD rats, and famotidine had no impact on depression. Overall our data suggested that the hypothalamic-pituitary-adrenal (HPA axis dysfunction may be the key role in triggering depression and stress ulcer. Acid-suppressing drugs and antidepressants could be used for treatment of depression and stress ulcer respectively. The occurrence of depression might be inhibited by blocking the central H(2 receptors.

    Helicobacter pylori is the major cause of active chronic gastritis and peptic ulcers in humans and has been linked to gastric carcinoma and lymphoma. The vacuolating cytotoxin vacA and cag pathogenicity island (cag PAI) are two identified virulence factors that are considered to have an important role in the pathogenesis of H. pylori infection. The aim of this study is to investigate the H. pylori vacA alleles in Iranian patients with peptic ulcer disease. In order to investigate this, biopsy specimens were obtained from 84 patients with gastric ulcer, gastritis, and duodenal ulcer. DNA extraction and PCR were used to detect the presence or absence of glmM, cagA and to assess the polymorphism of vacA. Of the 77 glmM PCR-positive biopsy specimens, 55 (71%) had the vacA signal sequence genotype s1, and 22 (29%) had subtype s2. vacA mid-region analysis revealed that 31 (40%) were vacA m1 and 46 (60%) were m2. The presence of the cagA gene correlated with vacA signal sequence type s1, whereas type s2 was predominantly found in cagA-negative samples (P detection of vacA and cagA, virulence markers described in several clinical outcomes may be used to help the treatment and prevention of H. pylori in Iran.

    In summary, a 32-year-old black man with homozygous sickle cell anemia has been presented. The patient developed bilateral ulcers of the leg which never completely healed. In one leg he demonstrated a focal, fusiform, periosteal reaction which probably in time would become incorporated into the cortex, resulting in the formation of an ulcer osteoma of the tibia associated with sickle cell disease. The ulcer osteoma has the same radiological appearance as the ulcer osteoma in individuals in Africa without sickle cell disease. (orig./SHA)

    Roentgenomorphological and functional signs of stomach and duodenum ulcer disease was studied in different age groups in 382 patients that were subjected to a complex of clinico-laboratory and roentgenological examinations. It is concluded that in different age groups ulcerous disease of stomach and duodenum is characterized by a considerable peculiarities of roengenomorphologic characters. In some age groups disclosed are characteristic symptomocomplexes of roentgenofunctional shifts typical of ulcers of different localisations. It is shown that there is a regular relation between the type of functional shifts, age of a patient and location of ulcers

Stomachs from all 5040 pigs that were slaughtered at Base Abattoir in Rwanda from August 2012 to August 2015 were examined for the presence and location of gastric ulcers. The results of the inspections were recorded and analyzed. Statistical analysis for Chi-square values was performed using the Software Package for Social Sciences version 16.0. The Z test for comparison of proportions was used and p0.05) from that in female pigs (12.84%) in all three districts. A significantly greater proportion of these ulcers (69.03%) was located in the esophageal region than in the glandular region of the stomach (30.97%) in slaughtered males (p<0.05). A significantly greater proportion of these ulcers (79.59%) was located in the esophageal region than in the glandular region of the stomach (20.41%) in slaughtered females (p<0.05). The overall incidence of esophageal ulcers (9.44%) in the slaughtered pigs was significantly (p<0.05) higher than that of glandular region ulcers (3.41%). Pigs with carcass weight over 60 kg showed a significantly (p<0.05) higher (44.44%) incidence of ulcers than those between 40 and 60 kg (33.33%) and those below 40 kg (22.22%). It was concluded that the incidence of gastric ulceration in slaughter pigs at Base Abattoir was not associated with source (district) or sex of pigs but was associated with the carcass weight.

    Various bio-sheet grafts have been attempted either to accelerate healing of artificial ulcers or to prevent adverse events after endoscopic submucosal dissection (ESD), but neither prospective nor mechanistic studies were available. To evaluate the substantial effect of a bio-sheet graft on artificial ulcer healing and its feasibility as an endoscopic treatment modality. Preclinical, in vivo animal experiment and proof-of-concept study. Animal laboratory. Three mini-pigs, Sus scrofa, mean age 14 months. Multiple ulcers sized 2.5 cm in diameter were generated by ESD in 3 mini-pigs and were assigned randomly into the following 3 groups; control group, bio-sheet group, or combination (bio-sheet plus drug) group. Bio-sheet grafts or bio-sheet plus drug combinations were applied on the artificial ulcers immediately after the ESD. Feasibility and efficacy of endoscopic bio-sheet graft therapy for the management of artificial ulcers and the evaluation of healing conditions based on histology changes in the remaining gastric bed tissues harvested from the stomachs. Thirty-three ESD specimens were obtained. On an image analysis of the ratio of healed area in the remaining gastric bed tissue compared with the matched dissected gastric mucosa, the control group showed the most significant improvement in healing activity among the 3 groups (P ulcer tissue was significantly attenuated in bio-sheet and combination groups (P ulcer beds, unexpected delayed ulcer healing was noted in the bio-sheet graft group because of its physical hindrance of the healing process.

    Full Text Available Abstract Background Gastric ulcers are a frequent problem in the United States. Proton pump inhibitors have been shown to increase healing rates and improve clinical symptoms. The objective of this study is to compare gastric ulcer healing rates for patients treated with a proton pump inhibitor (PPI (omeprazole, rabeprazole, pantoprazole, or lansoprazole, an histamine 2- receptor antagonist (ranitidine or placebo. Methods A literature search was conducted to identify randomized, controlled clinical trials that included a PPI in at least one treatment arm and assessed the gastric ulcer healing rates endoscopically. The healing rates were estimated for each treatment at specific time points, and Rate Ratios (RR and 95% confidence intervals (CI were estimated for each trial. Results Sixteen trials met the inclusion criteria: four compared a PPI versus placebo, nine compared a PPI versus ranitidine (no trials of rabeprazole versus ranitidine met the inclusion criteria, and three compared a newer PPI (lansoprazole, pantoprazole or rabeprazole versus omeprazole. In relation to ranitidine, the pooled RR of PPIs (lansoprazole, omeprazole and pantoprazole was 1.33 (95% CI 1.24 to 1.42 at four weeks. In each trial, greater improvement in the studied clinical symptoms was found with the newer PPIs (rabeprazole, pantoprazole and lansoprazole when compared to omeprazole. Conclusion In this study treatment with PPIs resulted in higher healing rates than ranitidine or placebo. This evidence suggests that the first choice for gastric ulcer treatment for the greater relief of symptoms is one of the newer PPIs.

    Soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) is elevated in the gastric juice and in cultures of gastric mucosa of patients with peptic ulcer disease (PUD). Its application as a surrogate marker for the treatment of PUD was assessed. From 138 eligible patients, 96 were enrolled; 50 with duodenal ulcer, 29 with gastric ulcer and 17 with chronic gastritis. Patients were endoscoped twice; once before treatment and once after treatment. Biopsy specimens were collected for histopathologic estimation of gastritis. Blood was sampled prior to each endoscopy. Serum was collected and sTREM-1 was measured by an enzyme immunoabsorbent assay ( http://www.clinicaltrials.gov identifier NCT00534443). At the end of treatment sTREM-1 was either: (a) below the limit of detection (this occurred in 62 patients and it was accompanied by lacks signs of residual disease in 58 patients, 93.5%); or (b) above the limit of detection (this occurred in 17 patients and it was accompanied by residual disease in 14 patients, 82.3%) (p peptic ulcer with sTREM-1 below detection limit was 5.30 (95% CI: 1.89-14.83, p detection. Serum sTREM-1 below detection limit may effectively distinguish patients who successfully completed therapy for PUD from those with residual disease and apply as a surrogate marker.

    The Helicobacter pylori cagA gene is a major virulence factor that plays an important role in gastric pathologies. DNA sequence data for the cagA 3' region of Western isolates differ markedly in their EPIYA motifs from those of East Asian isolates. An increase in the number of these motifs is known to be associated with gastric cancer. Whether such an association is also the case for peptic ulceration was investigated in this study. Gastric biopsies were collected from 96 patients with duodenal ulcer (DU), gastric ulcer (GU) and gastritis. The types of EPIYA motif detected by PCR among 28 DU strains were 13 ABC, eight ABCC, six ABCCC, and in one patient both ABC and ABCCCCC; among nine GU strains were two ABC, five ABCC and two ABCCC; and among 40 gastritis strains were 35 ABC and five ABCC. DNA sequencing was carried out to confirm the detection of the EPIYA motif types and to analyse their peptide sequences. A significant association was found between the number of the EPIYA-C motifs (>or=2) and peptic ulceration (P=0.00001) compared with gastritis. In conclusion, this study shows that our patients harboured cagA-positive H. pylori strains with EPIYA motifs of the Western type and that the increase in the number of EPIYA-C motifs was significantly associated with DU and GU but not with gastritis, indicating predictive association with the severity of the disease.

    The eradication rate of Helicobacter pylori (H. pylori) infection might be affected by the degree of inflammation of gastric mucosa represented by the endoscopic stage of peptic ulcer disease (PUD). The aims of this study were to evaluate the eradication rates of H. pylori infection according to the endoscopic stage of PUD and to document whether early eradication in the active stage could yield a higher eradication rate in patients with peptic ulcer bleeding (PUB). A total of 1,177 patients with PUD (380 gastric ulcer, 710 duodenal ulcer, and 87 combined ulcer) who received proton-pump inhibitor (PPI)-based triple therapy were included, and the eradication rates were compared by ulcer stage. Univariate and multivariate analyses were conducted to identify factors influencing eradication rate. In PUB, the eradication rates between the early eradication group (≤7 days) and the late eradication group (>7 days) were compared. The eradication rates according to endoscopic stage were significantly different in gastric ulcer (active vs healing vs scarring; 84.8% vs 82.7% vs 70.6%, p = .014, respectively), but there were no significant differences in duodenal ulcer (active vs healing vs scarring; 87.6% vs 80.9%% vs 80.9% p = .169, respectively). In multivariate analyses, active ulcer as well as age younger than 50 was a significantly independent predictor of successful eradication (Odds ratio; 2.799, 95% CI; 1.659-4.723, p = .0001). The eradication rate of the early eradication group was significantly higher than the late eradication group in PUB (89.2% vs 71.9%, 95% CI; 1.265-8.269, p = .011). There was a significant difference in the eradication rate according to the endoscopic stage of gastric ulcer. Active ulcer was an independent predictor of successful eradication. Furthermore, early H. pylori eradication should be considered in patients with PUB to yield a higher eradication rate. © 2015 John Wiley & Sons Ltd.

    Natural honey (NH) and Nigella sativa (NS) seeds have been in use as a natural remedy for over thousands of years in various parts of the world. The aim of this study was to assess the protective effects of NS (Nigella sativa) and NH (natural honey) on acetylsalicylic acid induced gastric ulcer in an experimental model with comparison to Cimetidine (CD). The study was conducted on 100 male albino rats, divided into 5 groups, with 20 animals in each group. Group A was used as a control and treated with Gum Tragacanth (GT). Eighty animals of the other groups were given acetylsalicylic acid (0.2 gm/kg body weight for 3 days) to produce ulcers by gavage. Two animals from each group were sacrificed for the detection of gastric ulcers. The remaining 72 animals were equally divided in four groups (B, C, D and E). The rats in group B, C and D were given NS, NH, and CD respectively while those in E were kept as such. No gastric lesions were seen in control group A while all the animals in group E revealed gastric ulcers. The animals of group B, C and D showed healing effects in 15/18 (83%), 14/18 (78%) and 17/18 (94%) animals grossly; 13/18 (72%), 14/18 (78%) and 16/18 (89%) rats showed recovery on microscopic examination respectively. The healing effects were almost the same in all three groups therefore, the statistical difference was not significant among them (p =0.40 and 0.65) while significant from group E (p=0.0000075, 0.0000016 and 0.0000012 respectively). NS and NH are equally effective in healing of gastric ulcer similar to cimetidine. Further broad spectrum studies as well as clinical trials should be conducted before the use of these products as routine medicines. (author)

    Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.

    Full Text Available This study investigated the protective effects of methanol extract of Vernonia amygdalina leaf (MEVA on aspirin induced gastric ulcer in rats. Thirty Wistar rats, 150–200 g were divided into six groups as follows: Group 1 (control rats received 2 mL/kg of propylene glycol for 28 consecutive days. Group 2 (Ulcer Control received 150 mg/kg/day of aspirin suspended in 3 mL of 1% carboxymethylcellulose in water orally for 3 consecutive days during which the rats were fasted for the induction of ulcer. Group 3 received cimetidine at 100 mg/kg/day orally for 28 consecutive days and thereafter treated as group 2. Groups 4, 5 and 6 received MEVA orally at 200, 300 and 400 mg/kg/day respectively for 28 consecutive days and thereafter were treated with aspirin as group 2. All the animals were sacrifice at the end of the study to determine the gastric pH, gastric acidity, gastric ulcer score, haematological indices, superoxide dismutase (SOD activity, reduced glutathione (GSH and Lipid peroxidation (LPO levels. The result showed that aspirin significantly (p < 0.05 increased gastric ulcer score and index, decreased gastric pH, gastric acidity, SOD activity, GSH level as well as increased LPO level. It induced significant necrosis of the stomach tissue. Administration of MEVA significantly (p < 0.05 increased gastric pH, but decreased gastric acid secretion and reversed alteration of haematological parameters. It also significantly (p < 0.05 increased SOD activity, GSH level and decreased LPO level. The results suggest that Vernonia amygdalina possesses gastro-protective properties against aspirin-induced gastric ulcer. Keywords: Vernonia amygdalina, Aspirin, Gastric ulcer, Antioxidant, Rat

    Whether or not the eradication of Helicobacter pylori is a risk factor for reflux esophagitis (RE) is a question at issue. To find an answer, it is necessary to clarify the influence of H. pylori eradication on the mechanism of RE. The authors investigated the influence of H. pylori eradication on gastric acidity and gastroesophageal reflux in ten gastric ulcer (GU) patients and ten duodenal ulcer (DU) patients by 24-h simultaneous determination of pH in the stomach and esophagus. Though the results indicated enhanced gastric acidity in GU patients at night after H. pylori eradication, no such influence was observed in DU patients. No significant changes in gastroesophageal reflux occurred in GU or DU patients before and after H. pylori eradication. RE after H. pylori eradication occurred in only one patient, with GU. This patient had several risk factors for RE, such as obesity, male sex, and dietary habits to add to the increase in gastric acidity at night that occurred after H. pylori eradication. No increase in gastroesophageal reflux occurred in any DU patients or in the other GU patients that demonstrated enhanced gastric acidity at night after H. pylori eradication. The cure of H. pylori infection does not, by itself, cause RE in patients who have few other risk factors for RE.

    The genomes of Helicobacter pylori (H. pylori) from different individuals are different. This project was to identify the strain specific DNA sequences between two clinical H. pylori isolates by suppression subtractive hybridization (SSH). Two clinical H. pylori isolates, one from gastric ulcer (GU, tester) and the other from non-ulcer dyspepsia (NUD, driver), were cultured and the genomic DNA was prepared and submitted to Alu I digestion. Then two different adaptors were ligated respectively to the 5'-end of two aliquots of the tester DNA fragments and SSH was made between the tester and driver DNA. The un-hybridized tester DNA sequences were amplified by two sequential PCR and cloned into pGEM-T-Easy Vector. The tester strain specific inserts were screened and disease related DNA sequences were identified by dot blotting. Among the 240 colonies randomly chosen, 50 contained the tester strain specific DNA sequences. Twenty three inserts were sequenced and the sizes ranged from 261 bp to 1 036 bp. Fifteen inserts belonged to the H.pylori plasmid pHPO100 that is about 3.5 kb and codes a replication protein A. Other inserts had patches of homologous to the genes of H.pylori in GenBank. Various patterns of dot blots were given and no GU strain unique DNA sequences were found when 4 inserts were used as probes to screen the genomic DNA from 27 clinical isolates, 8 from GU, 12 from duodenum ulcer (DU), 4 from GU-DU, 2 from NUD and 1 from gastric cancer (GC). But a 670 bp DNA fragment (GU198) that was a bit homologous to the 3'-end of the gene of thymidylate kinase was positive in 7 GU strains (7/8), 3 GU-DU strains (3/4) and 3 DU strains (3/12). A 384 bp fragment (GU79) of the replication gene A (repA) was positive only in 4 H.pylori isolates, 2 from GU and 2 from GU-DU. Differences exist in the genes of different H.pylori isolates. SSH is very effective to screen H.pylori strain specific DNA sequences between two clinical isolates, and some of these sequences may have

    Initial proton pump inhibitor (PPI)-based triple therapy for Helicobacter pylori (H. pylori) infection is less effective in patients with nonulcer dyspepsia (NUD) than those with peptic ulcer disease (PUD). To date, there have been no studies on the difference in eradication rates in NUD compared to PUD with regard to second-line therapy. Therefore, we retrospectively analyzed the difference in eradication rates of a second-line quadruple therapy for NUD and PUD patients. Between June 2003 and December 2005, patients who failed to respond to initial PPI-based triple therapy, received 7 days of quadruple therapy (PPI b.i.d., bismuth 300mg q.i.d., metronidazole 500mg t.i.d., tetracycline 500mg q.i.d.) as a second-line treatment regimen. Four weeks after the completion of the course of medication, a 13C-urea breath test was performed for detection of H. pylori. A total of 87 patients received second-line quadruple therapy. Of these, 43 patients had NUD and 44 patients had PUD (19 gastric ulcers, 23 duodenal ulcers, 2 both ulcers). The eradication rates were 76.7% (33/43) in the NUD group and 90.9% (40/44) in the PUD group by per-protocol analysis. Therefore, the eradication rates in the NUD group were significantly lower than those in the PUD group (p = 0.034). A 7-day bismuth-based second-line quadruple therapy for H. pylori infection was less effective in patients with NUD than those with PUD. Therefore, a more potent second-line treatment regimen or extension of treatment duration of quadruple therapy should be considered for the eradication of H. pylori in patients with NUD.

    AIM: To assess the frequency of herpes simplex virus type I in upper gastrointestinal tract ulcers and normal mucosa with the modern and better assays and also with a larger number of well characterized patients and controls and its relationship to Helicobacter pylori(H pylori). METHODS: Biopsy specimens from 90 patients (34 with gastric ulcer of the prepyloric area and 56 with duodenal ulcer) were evaluated. Biopsies from 50 patients with endoscopically healthy mucosa were considered as the control group. The method used to identify herpes simplex virus-1 (HSV-1) was polymerase chain reaction. H pylori was detected by the CLO-test and by histological method. RESULTS: Herpes simplex virus-1 was detected in 28 of 90 patients with peptic ulcer (31%) [11 of 34 patients with gastric ulcer (32.4%) and 17 of 56 with duodenal ulcer (30.4%)] exclusively close to the ulcerous lesion. All control group samples were negative for HSV-1. The likelihood of H pylori negativity among peptic ulcer patients was significantly higher in HSV-1 positive cases than in HSV-1 negative cases (P = 0.009). Gastric ulcer patients with HSV-1 positivity were strongly associated with an increased possibility of Helicobacter pylori negativity compared to duodenal ulcer patients (P = 0.010). CONCLUSION: HSV-1 is frequent in upper gastro-intestinal tract ulcers but not in normal gastric and duodenal mucosa. There is an inverse association between HSV-1 and H pylori infection.

    Maintenance of gastric pH above 4.0 aids the prevention of bile acid-mediated ulcerative damage to the pars esophageal tissue in pigs. One means of doing so is the addition of buffering compounds, such as sodium bicarbonate, to the water supply; however, any potential physiological effect of buffer consumption has yet to be determined. Experiment 1 tested the acute effects of buffer addition to the water supply on systemic acid-base and electrolyte balance in swine (BW 40.7 +/- 3.0 kg). Consumption of water calculated to a 200 mOsm solution with sodium bicarbonate for 24 h increased (P sodium bicarbonate can safely be added to the water supply for pigs, with no clinically relevant alterations in acid-base balance because the animals readily compensate for buffer intake.

    Although endoscopic submucosal dissection (ESD) is widely used to treat gastric neoplasms, there is no consensus for the optimal treatment for ESD-induced ulcers. We compared efficacy between 4 and 8 weeks of lansoprazole treatment for iatrogenic gastric ulcers that developed after ESD. Eighty-four patients who were diagnosed with gastric adenoma or early gastric cancer were enrolled and randomly assigned to treatment with lansoprazole (30 mg/day) for 4 or 8 weeks. Eight weeks after ESD, we conducted follow-up endoscopy to compare ulcer stage and ulcer reduction ratio (dividing the ulcer dimension at 8 weeks by the initial ulcer dimension) between the two groups. From the 84 patients, 69 patients were included in the final analysis, with 34 in the 4-week group and 35 in the 8-week group. Eight weeks after ESD, there were no significant difference observed between the two groups in terms of the ulcer stage (68 % in the scar stage in the 4-week group vs. 69 % in the 8-week group, P = 0.93) or the ulcer reduction ratio (0.0081 ± 0.015 in the 4-week group vs. 0.0037 ± 0.008 in the 8-week group, P = 0.15). Also, in the subgroup analysis among the patients with large ulcers (>30 mm), those parameters were not different. For ESD-induced gastric ulcers, treatment with lansoprazole for 4 weeks was as effective as treatment for 8 weeks. Considering cost-effectiveness, proton pump inhibitor therapy for 4 weeks may be sufficient for ESD-induced gastric ulcers.

    Aim: Since there is an increasing need for gastric ulcer therapies with optimum benefit-risk profile. This study was conducted to investigate gastro-protective effects of N-Acetylcysteine (NAC against ethanol-induced gastric ulcer models in mice. Materials and Methods: Forty-two mice were allocated into six groups consisting of 7 mice each. Groups 1 (normal control and 2 (ulcer control received distilled water at a dose of 10 ml/kg, groups 3, 4 and 5 were given NAC at doses 100, 300 and 500 mg/kg, respectively, and the 6th group received ranitidine (50 mg/kg. All drugs administered orally once daily for 7 days, on the 8th day absolute ethanol (7 ml/kg was administrated orally to all mice to induce the acute ulcer except normal control group. Then 3 h after, all animals were sacrificed then consequently the stomachs were excised for examination. Results: NAC administration at the tested doses showed a dose-related potent gastro-protective effect with significant increase in curative ratio, PH of gastric juice and mucus content viscosity seen with the highest dose of NAC and it is comparable with that observed in ranitidine group. Conclusion: The present findings demonstrate that, oral NAC shows significant gastro-protective effects comparable to ranitidine confirmed by antisecretory, cytoprotective, histological and biochemical data but the molecular mechanisms behind such protection are complex.

    Chronic venous disease (CVD) is a frequent disorder with a high socioeconomic impact. Little is known about the possible differences between healed ulcer (C5 group) and active ulcer (C6 group) in terms of disease severity and quality of life (QoL). Our aim was to determine the possible differences in severity disease and QoL between the C5-C6 and C1 (control) group. Data from a national, multicentre, observational and cross-sectional study (n = 1598) were used to compare three groups of CVD: C1 (n = 243), C5 (n = 136) and C6 (n = 70). CVD severity was assessed with the Venous Clinical Severity Score (VCSS) and QoL with the Short Form 12 Health Survey (SF-12) and Chronic Lower Limb Venous Insufficiency Questionnaire (CIVIQ-20). Patients with active ulcers had a higher mean total VCSS than patients with healed ulcers (P ulcers than in those with C1 (P ulcers (C6) had lower QoL scores, but the differences were not statistically significant. Patients with venous leg ulcers (C5-C6) are associated with high severity and poor QoL. However, the healing of a leg ulcer did not contribute to improvement of QoL.

    Peptic ulcer is a common disease that affects millions of people worldwide. Considering its global prevalence finding new approach for treating is important. The aim of this study was to investigate the effect of zinc sulfate on gastric and duodenal ulcer treatment. This double-blind clinical trial study was done on 90 patients who were admitted to the gastrointestinal endoscopy clinic of Tohid hospital in Sanandaj, Iran. All patients were diagnosed with gastric and duodenal ulcers. They were randomly divided into two-intervention and control groups, using block randomization with block sizes of 4. Patients and researcher were unaware of the grouping. To assess the level of zinc, blood samples were taken. In case of positive Rapid Urease Test (RUT), triple therapy regimen including amoxicillin, clarithromycin and omeprazole was administered for two weeks. For intervention group in addition to "triple therapy", an oral dose of Zinc Sulfate 220mg capsules were administered daily, while the control group received placebo capsules. A total of 54.5% and 57% of the patients in the intervention and control groups had gastric ulcer respectively. The Rapid Urease Test (RUT) result of 72.7% of intervention group and 83.3% of control group was positive (p = 0.24). Serum zinc level of 20.9% of intervention group and 35.7% of control group was lower than the normal level (p = 0.13). The mean of serum zinc level of intervention group and control group were 81.9 and 78.9 mg dL respectively (p = 0.4). After intervention, peptic ulcer in 81.8% of the intervention group and 83.3% of the control groups were improved (p= 0.85). Response to treatment were higher in patients with normal zinc levels compared to patients with abnormal levels (77.5% vs. 22.5%, p=0.019). A daily dose of 220mg zinc sulfate was not significantly effective on peptic ulcer. However, patients with normal zinc levels had better ulcer treatment.

    Full Text Available Helicobacter pylori (H. pylori infection is a definite causative factor for gastric ulcers (GUs. In the present study we detected a specific antigen of gastric epithelial cells (HGC-27 using cell ELISA, which was recognized by the sera of GU patients (n=20 but not in patients with chronic gastritis (CG; n=20 or in healthy volunteers (HC; n=10. This antigen was over-expressed by a stressful (heat-stressed environment, and was identified as elongation factor 2 kinase (EF-2K by western blotting. The GU patients' lymphocytes stimulated by H. pylori specifically disrupted heat-stressed HGC-27 cells in a cytotoxic assay. In flow cytometry, the effector cells (lymphocytes from GU patients were significantly differentiated to T helper type 1 lymphocyte (Th1 and cytotoxic T lymphocyte (CTL as opposed to those from CG patients. The target cells (HGC-27 expressed EF-2K and MHC-class I together with costimulatory molecules from heat stress. This antigen specific immune mechanism could have a prominent role in the pathogenesis of GU.

    To determine the effect of treatment with honey in piroxicam-induced gastric ulcer in Holtzman rats. 48 eight-week old female Holtzman rats, weights between 100 and 200 grams, were divided into 6 treatment groups as follow: Group A: water; Group B: piroxicam (30 mg/kg); Group C: omeprazole (5 mg/kg) and piroxicam (30 mg/kg); Group D: honey (2.5 g/kg) and piroxicam (30 mg/kg); Group E: honey (5 g/kg) and piroxicam (30 mg/kg); Group F: honey (7.5 g/kg) and piroxicam (30 mg/kg). Macroscopic studies, using Scion Image, and microscopic histological section of gastric mucosa were performed after the interventions. The results of the macroscopic studies showed statistically significant differences for both doses of honey at 6 g/kg and 7.5 g/kg when compared to piroxicam (p=0.016 and p=0.001 respectively) and the gastroprotective effect was similar when compared to omeprazole (p>0.05). Microscopic studies showed statistically significant differences only for dose at 7.5 g/kg when compared to piroxicam (p=0.0018) and the gastroprotective effect was similar to omeprazole (p=1). Dose of honey at 7.5 g/kg showed gastroprotective effect at microscopic and macroscopic studies when compared to omeprazole.

    An ethnopharmacological survey indicated that the leaves of Byrsonima intermedia A. Juss. (Malpighiaceae), a medicinal species commonly found in the Brazilian Cerrado, can be used against gastroduodenal disorders, such as gastric ulcers and diarrhea. The objective of this study was to evaluate the effects of a methanolic extract of Byrsonima intermedia (MBI) leaves on gastric and duodenal ulcers and to assess the antimicrobial and antidiarrheal effects of this extract. The anti-ulcerogenic effect of MBI was investigated with different ulcerogenic agents in rodents (mice and rats), including non-steroidal anti-inflammatory drug (NSAID), HCl/ethanol, pyloric ligature, absolute ethanol, cysteamine and ischemia-reperfusion. The gastroprotective effect of MBI was assessed by analysing the volume of gastric juice, pH, total acidity, mucus, NO, sulfhydryl compound, vanilloid receptor, glutathione (GSH) levels, and myeloperoxidase (MPO) activity in the gastric and duodenal mucosa. The gastric and duodenal healing effects of MBI were also evaluated during 7 or 14 days of treatment. The antidiarrheal action (measured by intestinal motility and diarrhea induced by castor oil) and anti-bacterial action of MBI against Staphylococcus aureus, Escherichia coli and Helicobacter pylori were also evaluated by microdilution methods. The phytochemical profile from MBI indicated the presence of phenolic acids, flavan-3-ols, oligomeric proanthocyanidins, and flavonoids. MBI (500mg/kg, p.o.) significantly inhibited totally gastric and duodenal lesions (69%) and healed gastric (49% on 14 days) and duodenal lesions (45% on 7 and 14 days). The MBI exert gastroprotective action by participation of endogenous sulfhydryl compounds, vanilloid receptors and increase in GSH level to effective gastric and duodenal protection. MBI also displayed curative (42%) and preventive (49%) antidiarrheal effects by involvement of opiate receptors and also antimicrobial effects in vitro. Byrsonima intermedia

    Limited data are available on the relative pharmacokinetics and pharmacodynamics of different omeprazole formulations. To compare pharmacokinetic and pharmacodynamic effects of a novel omeprazole formulation against a currently registered product. Masked 2 period, 2 treatment crossover. Twelve clinically healthy horses were studied over two 6-day treatment periods. Horses were randomly assigned to receive a novel omeprazole paste (Ulcershield: ULS) or a currently registered reference omeprazole product (OMO). Gastric pH was measured continuously for 10 h on the day prior to commencing treatment (Day -1) and after 6 days of oral treatment (Day 5) using in situ antimony pH probes within an indwelling nasogastric tube. Plasma pharmacokinetics were determined on Days 0 and 6. Treatment significantly (P<0.005) increased gastric pH on Day 5, compared to results obtained prior to treatment (Day -1) and there was no significant difference between products (P = 0.773). Similarly, comparison of median hourly gastric pH (P = 0.593), mean gastric pH (P = 0.154), percentage time pH<4 (P = 0.259) and area under the time-gastric pH response curve (P = 0.734) did not discriminate between products. Both treatments resulted in significantly lower gastric ulcer severity scores (both P = 0.004), with no difference between treatments (P = 0.688). Comparison of mean log area under time-plasma concentration curves demonstrated that, although the lower limit of the 90% confidence interval was within the -20% limit for bioequivalence, the upper limit was exceeded, suggesting that the test product could have greater bioavailability than the reference product. The small sample size, large interhorse plasma omeprazole concentrations, and low bioavailability of omeprazole impacted the sensitivity of the bioequivalence analysis. ULS matched or slightly exceeded OMO plasma concentrations. Both products resulted in equivalent increases in gastric pH, gastric pH profiles and decrease in gastric

    The analysis includes 58 patients with an ulcer in the duodenum, 40 patients with an ulcer in the stomach, and 13 persons making up the control group. In all patients submitted to the ratio-isotopic estimation of the duodeno-gastric reflux as well as to the chromatographic determination of the concentration of bile acids and lysolecithin in the gastric juice, an almost identically frequent occurrence of the reflux of the duodeno gastric contents into the ulcer of the stomach and of the duodenum was confirmed. It was shown that half of the ulcers of the stomach originate without the participation of the duodeno gastric reflux. It was also established that the average total concentrations of bile acids and lysolecithin are very high in the gastric juice, and in some even statistically significant cases, in the ulcer of the stomach in comparison with the remaining analysed groups of patients.

    Cibotium barometz is a medical herb used traditionally in the Malaysian peninsula for several ailments, including gastric ulcer. The aim of this study was assessment the anti-ulcer effects of C. barometz hair on ethanol-induced stomach hemorrhagic abrasions in animals. Seven groups of Sprague Dawley (SD) rats were administered 10% Tween 20 in the normal control and ulcer control groups, and omeprazole 20 mg/kg and 62.5, 125, 250, and 500 mg/kg of C. barometz hair extract in the experimental groups. After 60 min, the normal control group of rats was orally administered 10% Tween 20, while absolute ethanol was orally administered to the groups of ulcer control, omeprazole and experimental groups. Stomachs of the rats were examined macroscopically and histologically. Homogenates of stomachs were used to evaluate endogenous antioxidant enzyme activities. Rats pre-fed with plant extract presented a significant decrease in the sore area, increased pH of gastric contents and preserved stomach wall mucus compared to the ulcer group. Histologically, rats pre-fed with C. barometz hair extract showed mild to moderate disruptions of the surface epithelium while animals pre-fed with absolute ethanol showed severe disruptions of the stomach epithelium with edema and leucocyte penetration of the submucosal layer. A Periodic acid Schiff (PAS) staining revealed that each rat pre-treated with the plant extract displayed an intense uptake of stomach epithelial glycoprotein magenta color compared to the ulcer control group. Immunohistochemical analysis revealed that rats pre-fed with the plant extract showed an up-regulation of the heat shock protein 70 (HSP70) and down-regulation of Bax proteins compared to ulcer control rats. Homogenates of the stomach tissue demonstrated significant increases in the endogenous antioxidant enzymatic activity and decreased lipid peroxidation (MDA) in rats pre-treated with C. barometz hair extract compared with the ulcer control rats.

    AIM: To assess the impact of Helicobacter pylori (H. pylori) genotypes and patient age and sex on the development of gastric diseases. METHODS: H. pylori-infected patients (n = 233) referred to the endoscopy unit at Tehran University of Medical Sciences (Tehran, Iran) were diagnosed with chronic gastritis (CG), gastric ulcer (GU), or duodenal ulcer (DU). Brucella blood agar was used for biopsy cultures and H. pylori isolation under microaerobic conditions. H. pylori isolates were confirmed with biochemical tests and through amplification of the 16S rRNA gene. DNA was extracted from fresh cultures of the H. pylori isolates and used for amplification of vacA alleles and the cagA gene. Statistical analysis was performed to determine the association between H. pylori genotypes, age ( 40 years) and sex of the patient, and gastric diseases. RESULTS: CG was the most prevalent gastric disease (113/233; 48.5%), compared to GU (64/233; 27.5%) and DU (56/233; 24%). More patients were male, and gastric diseases were more frequent in patients > 40 years (P 40 years was more common in females (18.5%) than males (11.6%) (P = 0.05), whereas a diagnosis of GU or DU in patients > 40 years was more frequent in males (14.6% vs 10.7% and 12.4% vs 4.3%, respectively). Overall, genotyping of the H. pylori isolates revealed that the vacA s1 (82%), vacA m2 (70%), and cagA+ (72.5%) alleles were more frequent than vacA s2 (18%), vacA m1 (29.2%), and cagA- (all P pylori infection is the result of interaction between bacterial genotypes and the age and sex of infected individuals.

    The present work is an attempt to elucidate the antiulcer activity of indole-3-carbinol (I3C), which is one of the anticarcinogenic phytochemicals found in the vegetables of Cruciferae family such as broccoli and cauliflower, alone or in combination with omeprazole (OMP), a proton pump inhibitor, to diminish the effects of induced acute gastric ulcer by aspirin (ASA) in male albino rats. A total of 48 adult male albino rats were used in the present study. Animals were divided into eight experimental groups (six animals each group). They were given different experimental inductions of ASA at a dose of 500 mg/kg/body weight, OMP at a dose of 20 mg/kg/body weight and I3C at a dose of 20 mg/kg/body weight either alone or in combination with each other orally for a duration of 7 days. Inner stomach features, ulcer index, pH activity, body weight, stomach weight, hematological investigations, serum total protein albumin and reduced glutathione activity were investigated in addition to the histological, histochemical and immunohistochemical stain of cyclooxygenase-2 to the stomach tissue of normal control, ulcerated and treated ulcerated rats. The results of this study revealed that oral administration of ASA to rats produced the expected characteristic mucosal lesions. OMP accelerated ulcer healing but the administration of I3C either alone or in combination with OMP to ASA-ulcerated rats produced a profound protection to the gastric mucosa from injury induced by ASA. Our results suggested that administration of antiulcer natural substances such as I3C in combination with the perused treatment such as OMP is a very important initiative in the development of new strategies in ulcer healing.

    BACKGROUND: Crohn's disease and ulcerative colitis are the two major forms of inflammatory bowel disease; treatment strategies have historically been determined by this binary categorisation. Genetic studies have identified 163 susceptibility loci for inflammatory bowel disease, mostly shared...... between Crohn's disease and ulcerative colitis. We undertook the largest genotype association study, to date, in widely used clinical subphenotypes of inflammatory bowel disease with the goal of further understanding the biological relations between diseases. METHODS: This study included patients from 49...... centres in 16 countries in Europe, North America, and Australasia. We applied the Montreal classification system of inflammatory bowel disease subphenotypes to 34,819 patients (19,713 with Crohn's disease, 14,683 with ulcerative colitis) genotyped on the Immunochip array. We tested for genotype...

    To report on corneal ulceration in ocular graft-versus-host disease (GVHD). This was a retrospective, observational case series investigating corneal ulceration and perforation in a cohort of ocular GVHD patients seen between June 2007 and October 2012. Four of 243 ocular GVHD patients developed corneal ulcerations attributable to ocular GVHD, and all four cases involved bilateral corneal ulceration. The median length of time from the diagnosis of ocular GVHD to the diagnosis of the first corneal ulceration was 317 days (range 168-434). The median length of time between the diagnosis of corneal ulceration in each patient's first and second eye was 248 days (range 9-645). Outcomes varied from complete resolution with medical treatment to corneal perforation necessitating penetrating keratoplasty. In cases of corneal perforation, the median length of time from the diagnosis of corneal ulceration to perforation was 10 days (range 0-20). Common clinical features included: centrally or paracentrally located ulcerations and perforations, concomitant dry eye, and the use of topical or systemic corticosteroids. Frequent follow-up and bilateral monitoring are highly recommended in cases of ocular GVHD-associated stromal thinning, as bilateral involvement or rapid progression to corneal perforation can occur.

    Novel raft forming systems incorporating curcumin-Eudragit® EPO solid dispersions were developed to prolong the gastric residence time and provide for a controlled release therapy of curcumin to treat gastric ulcers. The solid dispersions of curcumin with Eudragit® EPO were prepared by the solvent evaporation method at various ratios to improve the solubility and the dissolution of curcumin. The optimum weight ratio of 1:5 for curcumin to Eudragit® EPO was used to incorporate into the raft forming systems. The raft forming formulations were composed of curcumin-Eudragit® EPO solid dispersions, sodium alginate as a gelling polymer and calcium carbonate for generating divalent Ca(2+) ions and carbon dioxide to form a floating raft. All formulations formed a gelled raft in 1min and sustained buoyancy on the 0.1N hydrochloric acid (pH 1.2) surface with a 60-85% release of curcumin within 8h. The curative effect on the acetic acid-induced chronic gastric ulcer in rats was determined. The curcumin raft forming formulations at 40mg/kg once daily showed a superior curative effect on the gastric ulcer in terms of the ulcer index and healing index than the standard antisecretory agent: lansoprazole (1mg/kg, twice daily) and a curcumin suspension (40mg/kg, twice daily). These studies demonstrated that the new raft forming systems containing curcumin solid dispersions are promising carriers for a stomach-specific delivery of poorly soluble lipophilic compounds.

    Gastric ulcers are common in domestic horses and foals, affecting at least 90% of unmedicated racehorses in active training. Despite these high prevalences in domestic horses, literature about this condition in wild equids is almost nonexistent. The presence of gastric ulcers was evaluated at necropsy in six species of wild equids that died at the Réserve Africane de Sigean, a safari park in the south of France from 2010 to 2016. Among the 55 individuals that died during that period, a description of the gastric mucosa was available in 82% (45/55) of cases. Considering the cases for which a description of the gastric mucosa was available, the prevalence of gastric ulcers was 64% (29/45). The highest prevalences were noted in Grant's zebra (Equus quagga boehmi) and Hartmann's mountain zebra (Equus zebra hartmannae) at 83% and 100%, respectively. In contrast to what is reported in domestic foals, gastric ulcerations were only diagnosed in one foal (out of 11 foals necropsied). The higher prevalence was noted in young individuals (3-36 mo old) at 93% (14/15); the lesions observed consisted mainly of single to multiple, superficial lesions, of which, only the mucosa was missing; these superficial lesions are often considered not clinically significant. The prevalence was lower for adults (74%; 14/19), but lesions were deeper or with a hyperemic or inflammatory appearance. All the lesions observed were located in the gastric, nonglandular, stratified squamous mucosa, along the margo plicatus. No statistical correlation could be found between the development of gastric ulcers and an ongoing, chronic pathologic process or a digestive tract pathology. The detection of gastric ulcers was, therefore, significantly greater in wild equids isolated in smaller enclosures. Nevertheless, additional larger-scale research is needed to point out predisposing factors in equids under human care.

    Non-steroidal anti-inflammatory drug (NSAID) use increases the risk of gastrointestinal complications such as ulcers or bleeding. The presence of factors like advanced age, history of peptic ulcer, Helicobacter pylori infection and the use of anticoagulants or antiplatelet agents increase this risk further. COX-2 inhibitors and antisecretory drugs, particularly proton pump inhibitors, help to minimize the risk of gastrointestinal complications in high-risk patients. This review presents a practical approach to the prevention and treatment of NSAID-associated peptic ulcer disease and examines the new advances in the rational use of NSAIDs.

    Abstract Objectives This study investigated whether the tongue inspection technique in Traditional Chinese Medicine (TCM) can be used as a noninvasive auxiliary diagnostic tool to differentiate the subtypes of peptic ulcer disease (PUD) and as an indicator of therapeutic efficacy. Subjects and methods A total of 198 outpatients from the China Medical University Hospital were recruited. The control group comprised 50 healthy adults. The remaining 148 patients were diagnosed with gastric ulcer, duodenal ulcer, or Helicobacter pylori (Hp) infection using upper gastrointestinal (GI) endoscopy, biopsy, and Campylobacter-like organism test. Tongue appearance was evaluated by a physician experienced in clinical Chinese medicine. Images of the tongue were immediately recorded using a high-resolution digital camera system. Results The affected group of 148 patients received an 8-week course of ulcer therapy. Of these, 108 patients infected with Hp were subjected to triple therapy in the first week. Forty-nine of these 108 cases infected with Hp completed secondary examination of upper GI endoscopy and tongue inspection. Forty-one of 49 cases (83.7%) were fully cured of Hp infection. These results showed that the color of the tongue body did not change in the cured patients; however, tongue fur was markedly thinner with a color change to white (ptongue inspection can be potentially used as a noninvasive auxiliary diagnostic method and as an indicator for clinical outcomes for patients with PUD.

    During Helicobacter pylori (H. pylori) infection CD4 + T cells in the gastric lamina propria are hyporesponsive and polarized by Th1/Th17 cell responses controlled by Treg cells. The objective of this study was to determine the number of Th17 cells in gastric mucosa of patients with gastritis and peptic ulcer and determined the relationship between main virulence factor of H. pylori and Th17 cells. A total of 89 H. pylori-infected gastritis patients, 63 H. pylori-infected peptic ulcer patients and 48 H. pylori-negative non-ulcer dysplasia patients were enrolled in this study. The number of Th17 was determined by immunohistochemistry. IL-8 and IL-17A expressions were determined by real-time polymerase chain reaction (qPCR). Also, the grade of chronic and active inflammation was investigated for involvement according to the density of neutrophils and mononuclear in gastric mucosal crypts, from one to all crypts. The number of Th17 cells and the expression of IL-8 and IL-17A in infected patients were significantly higher than uninfected subjects. The number of Th17 cells and the expression of IL-8 and IL-17A in infected patients with peptic ulcer were significantly higher than patients with gastritis. Additionally, the numbers of Th17 cells as well as the expression of IL-8 and IL-17A were positively correlated with the degree of H. pylori density in infected patients with peptic ulcer, while this correlation was negative in infected patients with gastritis. The numbers of Th17 cells as well as the expression of IL-8 and IL-17A were positively correlated with the degree of chronic inflammation. The predominant Th17 cell responses may play a role in the pathogenesis of peptic ulcers disease in infected patients. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available BACKGROUND: The current study was carried out to examine the gastroprotective effects of Parkia speciosa against ethanol-induced gastric mucosa injury in rats. METHODOLOGY/PRINCIPAL FINDINGS: Sprague Dawley rats were separated into 7 groups. Groups 1-2 were orally challenged with carboxymethylcellulose (CMC; group 3 received 20 mg/kg omeprazole and groups 4-7 received 50, 100, 200 and 400 mg/kg of ethanolic leaf extract, respectively. After 1 h, CMC or absolute ethanol was given orally to groups 2-7. The rats were sacrificed after 1 h. Then, the injuries to the gastric mucosa were estimated through assessment of the gastric wall mucus, the gross appearance of ulcer areas, histology, immunohistochemistry and enzymatic assays. Group 2 exhibited significant mucosal injuries, with reduced gastric wall mucus and severe damage to the gastric mucosa, whereas reductions in mucosal injury were observed for groups 4-7. Groups 3-7 demonstrated a reversal in the decrease in Periodic acid-Schiff (PAS staining induced by ethanol. No symptoms of toxicity or death were observed during the acute toxicity tests. CONCLUSION: Treatment with the extract led to the upregulation of heat-shock protein 70 (HSP70 and the downregulation of the pro-apoptotic protein BAX. Significant increases in the levels of the antioxidant defense enzymes glutathione (GSH and superoxide dismutase (SOD in the gastric mucosal homogenate were observed, whereas that of a lipid peroxidation marker (MDA was significantly decreased. Significance was defined as p<0.05 compared to the ulcer control group (Group 2.

  19. High-mobility group box 1 inhibits gastric ulcer healing through Toll-like receptor 4 and receptor for advanced glycation end products.

    Directory of Open Access Journals (Sweden)

    Yuji Nadatani

    Full Text Available High-mobility group box 1 (HMGB1 was initially discovered as a nuclear protein that interacts with DNA as a chromatin-associated non-histone protein to stabilize nucleosomes and to regulate the transcription of many genes in the nucleus. Once leaked or actively secreted into the extracellular environment, HMGB1 activates inflammatory pathways by stimulating multiple receptors, including Toll-like receptor (TLR 2, TLR4, and receptor for advanced glycation end products (RAGE, leading to tissue injury. Although HMGB1's ability to induce inflammation has been well documented, no studies have examined the role of HMGB1 in wound healing in the gastrointestinal field. The aim of this study was to evaluate the role of HMGB1 and its receptors in the healing of gastric ulcers. We also investigated which receptor among TLR2, TLR4, or RAGE mediates HMGB1's effects on ulcer healing. Gastric ulcers were induced by serosal application of acetic acid in mice, and gastric tissues were processed for further evaluation. The induction of ulcer increased the immunohistochemical staining of cytoplasmic HMGB1 and elevated serum HMGB1 levels. Ulcer size, myeloperoxidase (MPO activity, and the expression of tumor necrosis factor α (TNFα mRNA peaked on day 4. Intraperitoneal administration of HMGB1 delayed ulcer healing and elevated MPO activity and TNFα expression. In contrast, administration of anti-HMGB1 antibody promoted ulcer healing and reduced MPO activity and TNFα expression. TLR4 and RAGE deficiency enhanced ulcer healing and reduced the level of TNFα, whereas ulcer healing in TLR2 knockout (KO mice was similar to that in wild-type mice. In TLR4 KO and RAGE KO mice, exogenous HMGB1 did not affect ulcer healing and TNFα expression. Thus, we showed that HMGB1 is a complicating factor in the gastric ulcer healing process, which acts through TLR4 and RAGE to induce excessive inflammatory responses.

    AIM: To investigate the prevalence and risk factors of asymptomatic peptic ulcer disease (PUD) in a general Taiwanese population. METHODS: From January to August 2008, consecutive asymptomatic subjects undergoing a routine health check-up were evaluated by upper gastrointestinal endoscopy. Gastroduodenal mucosal breaks were carefully assessed, and a complete medical history and demographic data were obtained from each patient. Logistic regression analysis was conducted to identify independent risk factors for asymptomatic PUD. RESULTS: Of the 572 asymptomatic subjects, 54 (9.4%) were diagnosed as having PUD. The prevalence of gastric ulcer, duodenal ulcer and both gastric and duodenal ulcers were 4.7%, 3.9%, and 0.9%, respectively. Multivariate analysis revealed that prior history of PUD [odds ratio (OR), 2.0, 95% CI: 1.3-2.9], high body mass index [body mass index (BMI) 25-30: OR, 1.5, 95% CI: 1.0-2.2; BMI > 30 kg/m2: OR, 3.6, 95% CI: 1.5-8.7] and current smoker (OR, 2.6, 95% CI: 1.6-4.4) were independent predictors of asymptomatic PUD. In contrast, high education level was a negative predictor of PUD (years of education 10-12: OR, 0.5, 95% CI: 0.3-0.8; years of education > 12: OR, 0.6, 95% CI: 0.3-0.9). CONCLUSION: The prevalence of PUD in asymptomatic subjects is 9.4% in Taiwan. Prior history of PUD, low education level, a high BMI and current smoker are independent risk factors for developing asymptomatic PUD. PMID:21448426

    We analysed the CT examinations of 109 patients with 197 involved bowel locations. 81 patients suffered from Crohn's disease, 28 from ulcerative colitis. Diagnosis was based on the combination of clinical, endoscopic and histopathologic findings. Three radiologists evaluated the CT series concerning the presence of morphologic changes analogous to conventional radiographic findings. In Crohn's disease, we found irregular outer contours in 26% of cases. The bowel wall was thickened in 82%. In acute phases, the bowel wall was thickened in 100%. Abscess and fistula as complications of inflammatory disease were present in 26 and 14% respectively. In ulcerative colitis, a target sign of the bowel wall was present in 40%, whereas in Crohn's disease a homogeneous wall density was present in all but two cases. Reduced attenuation due to submucosal fat deposits was found in 16% and mucosal tunneling in 27% of cases with ulcerative colitis. Even if severe mucosal destructions were found, the outer contour of the gut was smooth and regular in 95% of the ulcerative colitis cases. CT can provide additional information on acuity, extent and complications in inflammatory bowel disease. In combination with conventional radiographic findings a three-step classification for Crohn's disease and ulcerative colitis (early changes, acute and chronic phase) can be proposed. (orig./MG) [de

    The resistance rate of Helicobacter pylori is gradually increasing. We aimed to evaluate the efficacy of levofloxacin-based third-line H. pylori eradication in peptic ulcer disease. Between 2002 and 2014, 110 patients in 14 medical centers received levofloxacin-based third-line H. pylori eradication therapy for peptic ulcer disease. Of these, 88 were included in the study; 21 were excluded because of lack of follow-up and one was excluded for poor compliance. Their eradication rates, treatment regimens and durations, and types of peptic ulcers were analyzed. The overall eradiation rate was 71.6%. The adherence rate was 80.0%. All except one received a proton-pump inhibitor, amoxicillin, and levofloxacin. One received a proton-pump inhibitor, amoxicillin, levofloxacin, and clarithromycin, and the eradication was successful. Thirty-one were administered the therapy for 7 days, 25 for 10 days, and 32 for 14 days. No significant differences were observed in the eradication rates between the three groups (7-days, 80.6% vs 10-days, 64.0% vs 14-days, 68.8%, p=0.353). Additionally, no differences were found in the eradiation rates according to the type of peptic ulcer (gastric ulcer, 73.2% vs duodenal/gastroduodenal ulcer, 68.8%, p=0.655). Levofloxacin-based third-line H. pylori eradication showed efficacy similar to that of previously reported first/second-line therapies.

    To evaluate the incidence, surgery, mortality, and readmission of upper gastrointestinal bleeding (UGIB) secondary to peptic ulcer disease (PUD). Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta, Canada from 2004 to 2010 (n = 7079) using the International Classification of Diseases Codes (ICD-10). A subset of the data was validated using endoscopy reports. Positive predictive value and sensitivity with 95% confidence intervals (CI) were calculated. Incidence of UGIB secondary to PUD was calculated. Logistic regression was used to evaluate surgery, in-hospital mortality, and 30-d readmission to hospital with recurrent UGIB secondary to PUD. Co-variants accounted for in our logistic regression model included: age, sex, area of residence (i.e., urban vs rural), number of Charlson comorbidities, presence of perforated PUD, undergoing upper endoscopy, year of admission, and interventional radiological attempt at controlling bleeding. A subgroup analysis (n = 6356) compared outcomes of patients with gastric ulcers to those with duodenal ulcers. Adjusted estimates are presented as odds ratios (OR) with 95%CI. The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were 85.2% (95%CI: 80.2%-90.2%) and 77.1% (95%CI: 69.1%-85.2%), respectively. The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per 100000. Overall risk of surgery, in-hospital mortality, and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%, 8.5%, and 4.7%, respectively. Interventional radiology to control bleeding was performed in 0.6% of patients and 76% of these patients avoided surgical intervention. Thirty-day readmission significantly increased from 3.1% in 2004 to 5.2% in 2010 (OR = 1.07; 95%CI: 1.01-1.14).

    With the purpose of improvement of diagnosis of induced gastric ulcer were examined 11 patients who took aggressive agents for simulation of gastric ulcer and 33 patients who took pseudo-aggressive agents. Observables, conduced diagnosis of local chemical burn of mucous coat of stomach during initial 6 days after taking aggressive agents. Stages of ulcerous process, resulting from local chemical burn of mucous coat of stomach, coressponds to real gactric ulcer. Gelatin capsule using as a container for delivery of aggressive agents, melts in stomach in 5-6 minutes after taking. Independent from body position, mucous coat of greater curvature of the stomach is damaged. It is impossible to simulate duodenal bulb ulcer using the gelatine capsule or ball made of breadcrumb. The last method of delivery of aggressive agent can damage the small intestine because of uncontrollability of the place of breaking the ball.

    Full Text Available The healing activity of gallic acid enriched ethanolic extract (GAE of Phyllanthus emblica fruits (amla against the indomethacin-induced gastric ulceration in mice was investigated. The activity was correlated with the ability of GAE to alter the cyclooxygenase- (COX- dependent healing pathways. Histology of the stomach tissues revealed maximum ulceration on the 3rd day after indomethacin (18 mg/kg, single dose administration that was associated with significant increase in inflammatory factors, namely, mucosal myeloperoxidase (MPO activity and inducible nitric oxide synthase (i-NOS expression. Proangiogenic parameters such as the levels of prostaglandin (PG E2, vascular endothelial growth factor (VEGF, hepatocyte growth factor (HGF, von Willebrand Factor VIII, and endothelial NOS (e-NOS were downregulated by indomethacin. Treatment with GAE (5 mg/kg/day and omeprazole (3 mg/kg/day for 3 days led to effective healing of the acute ulceration, while GAE could reverse the indomethacin-induced proinflammatory changes of the designated biochemical parameters. The ulcer healing activity of GAE was, however, compromised by coadministration of the nonspecific NOS inhibitor, N-nitro-L-arginine methyl ester (L-NAME, but not the i-NOS-specific inhibitor, L-N6-(1-iminoethyl lysine hydrochloride (L-NIL. Taken together, these results suggested that the GAE treatment accelerates ulcer healing by inducing PGE2 synthesis and augmenting e-NOS/i-NOS ratio.

    The high prevalence of Helicobacter pylori (H. pylori) infection in eastern Siberia is consistently established. In the same geographic area, however, fragmentary information is available on the epidemiology of the peptic ulcer disease (PUD). To assess the prevalence of H. pylori infection (including CagA status) and PUD in different eastern Siberian ethnicities. An endoscopy population of 3149 eastern Siberian dyspeptic patients was considered [1727 Europoids and 1422 Mongoloids (Evenks = 792; Khakases = 630)]. H. pylori status was assessed by urease test and/or serum anti-H. pylori IgG and/or histology. CagA status was serologically assessed (anti-CagA antibodies). All the Siberian ethnicities featured high rates of H. pylori infection (Europoids = 87.1%, Evenks = 88.6%, Khakases = 85.4%). Among the 1504 H. pylori-positive Europoids, the prevalence of CagA-positive status (68.7%) was significantly higher than that featured by the 1240 H. pylori-positive Mongoloid ethnicities (46.9%; p Peptic ulcer disease significantly prevailed among Europoids (prevalence among Europoid Evenks and Khakases: 8.9% and 8.3%, respectively; prevalence among Mongoloid Evenks and Khakases = 1.0% and 4.4%, respectively). eastern Siberian populations feature consistent high rates of H. pylori infection, but different prevalence of peptic ulcer disease. In particular, Europoids featured a prevalence of both CagA-positive status and peptic ulcer disease significantly higher than that of the Mongoloid ethnicities. These results suggest that both environmental factors (coexisting with the H. pylori infection) and host-related variables modulate the clinicopathological expression of the H. pylori -associated gastric diseases. © 2016 John Wiley & Sons Ltd.

    This study investigates the gastroprotective effects of hecogenin, a steroid saponin isolated from Agave sisalana, on experimental models of gastric ulcer. Male Swiss mice were used in the models of ethanol- and indometacin-induced gastric ulcer. To clarify the hecogenin mechanism of action, the roles of nitric oxide (NO), sulfhydryls (GSH), K⁺(ATP) channels and prostaglandins were also investigated, and measurements of lipid peroxidation (TBARS assay) and nitrite levels in the stomach of hecogenin-treated and untreated animals were performed. Furthermore, the effects of hecogenin on myeloperoxidase (MPO) release from human neutrophils were assessed in vitro. Our results showed that hecogenin (3.1, 7.5, 15, 30, 60 and 90 mg/kg, p.o.) acutely administered, before ethanol or indomethacin, exhibited a potent gastroprotective effect. Although the pretreatments with L-NAME, an iNOS inhibitor, and capsazepine, a TRPV1 receptor agonist, were not able to reverse the hecogenin effect, this was reversed by glibenclamide, a K⁺(ATP) blocker, and indomethacin in the model of ethanol-induced gastric lesions. The hecogenin pretreatment normalized GSH levels and significantly reduced lipid peroxidation and nitrite levels in the stomach, as evaluated by the ethanol-induced gastric lesion model. The drug alone increased COX-2 expression and this effect was further enhanced in the presence of ethanol. It also decreased MPO release and significantly protected the gastric mucosa. In conclusion, we showed that hecogenin presents a significant gastroprotective effect that seems to be mediated by K⁺(ATP) channels opening and the COX-2/PG pathway. In addition, its antioxidant and anti-inflammatory properties may play a role in the gastroprotective drug effect. Copyright © 2012 Elsevier B.V. All rights reserved.

  15. Gastric emptying

    1986-01-01

    Radionuclide techniques appear to be the current method of choice for determining the rate and pattern of gastric emptying. Isotopic methods are quantitative, noninvasive in that they do not require intubation, may be used with solid meals for greater sensitivity, present a low radiation burden to the patient compared to the burden of radiographic techniques, and are suitable and acceptable to the patient for repetitive studies. By comparison, other methods are either invasive, nonquantitative, or nonphysiologic. Of the radionuclide methods currently available, the solid meals (either liver or egg) are best, and dual liquid-solid studies offer additional physiologic data. It is now known that gastric emptying abnormalities may result from common disorders such as diabetes mellitus or gastric or duodenal ulcer disease, may be caused by a variety of medications, may follow gastric surgery, or may result from less well understood disorders, such as Zollinger-Ellison syndrome. By helping to clarify these gastric emptying abnormalities, the physician's ability to treat disorders of gastric emptying with diet, medication, and surgery is enhanced in accuracy and precision. Using these newer radionuclide techniques will permit both the clinician and the investigator a better understanding than was previously possible of gastric physiology in both health and disease

  16. A Direct Comparison of Anti-ulcer Effects of Coenzyme Q10 and Vitamin C on Indomethacin-induced Gastric Ulcer in Rat: A Controlled Experimental Study

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Introduction: Indomethacin increases generation of mitochondrial reactive oxygen species (ROS which have a crucial role in the indomethacin-induced gastric ulcer. Coenzyme Q10 has an antioxidant activity on mitochondria and cell membranes and protects lipids from oxidation and is essential for stabilizing biological membranes. Superoxide dismutase (SOD acts as one of the defense mechanisms against free radicals. When the generation of ROS overwhelms, the antioxidant defense, lipid peroxiation of cell membrane occurs and cause cell damage. Materials and Methods: Male adult Wistar rats were divided into A and B groups. The rats in group A were then further divided into three subgroups of 6 animals each and received one of the following treatments: Animals in the first subgroup received saline. Animals in the second subgroup received saline and indomethacin. Animals in the third subgroup received vitamin C and indomethacin. The rats in group B were also further divided into 3 subgroups of 6 rats each and treated with one of the following treatments: Animals in first subgroup received 1% Tween 80 as vehicle. Animals In second subgroup received 1% Tween 80 and indomethacin. Animals in third subgroup received CoQ10 and indomethacin. Four hours after the last treatment, animals were killed and the stomachs removed were cut and gastric mucosal lesions were examined. Ulcer indexes were determined and SOD activity measured in plasma                                                             Results: Pretreatment with both vitamin C and coenzyme Q10 was associated with attenuation of ulcer index and increased SOD activity compared with animals treated with indomethacin alone (P

    Radix Codonopsis has been used in traditional Chinese medicine for strengthening the immune system, improving poor gastrointestinal function, treating gastric ulcers and chronic gastritis and so on. In the present study, an inulin-type fructan CP-A was obtained from the roots of Codonopsis pilosula (Franch.) Nannf. and its structure was confirmed by MS and NMR as (2 → 1) linked-β-d-fructofuranose. The protective effects of CP-A against ethanol-induced acute gastric ulcer in rats were intensively investigated. A Lacy assay demonstrated that CP-A-treated group (50 mg/kg) showed the gastric damage level 1, which was similar to the positive control group, while the model group exhibited the gastric damage level 3. The Guth assay demonstrated that the mucosa ulcer index for CP-A groups at the doses of 50 mg/kg and 25 mg/kg significantly decreased compared with that in the model group ( p CP-A significantly increased the activities of SOD and GSH-Px, and decreased the contents of MDA and NO, and the activity of MPO in gastric tissue in a dose-dependent manner ( p CP-A were likely the potential component in Radix Codonopsis for treatment of acute gastric ulcers.

    There are increasing evidences for gastrointestinal motility disorder (GIMD) and gastric stress ulcer induced by noise stress. The present study was to investigate the reversed effect of melatonin on GIMD and gastric stress ulcer induced by noise stress and potential mechanism. Noise stress was induced on rats, and melatonin (15 mg/kg) was administered to rats by intraperitoneal injection. Differences were assessed in gastric residual rate (GRR), small intestine propulsion rate (SPR), Guth injury score, cortisol, gastrointestinal hormones (calcitonin-gene-related peptide and motilin) and oxidative stress markers (superoxide dismutase and malondialde hyde) in blood plasma as well as gastric mucosa homogenate with or without melatonin. The pathological examination of gastric mucosa was also performed. The GRR and SPR were improved by noise stress compared with control (P stress ulcer. Moreover, the levels of cortisol, motilin and malondialdehyde in blood plasma and ma-londialdehyde in gastric mucosa homogenate were increased by noise stress (P stress ulcer induced by noise stress. The underlying mechanism may be involved in oxidative stress and gastrointestinal hormones.

    Overtreatment with topical ophthalmic preparations can lead to toxic corneal ulcer development. This study aimed to investigate the clinical and visual impact of toxic corneal ulcers and the management and risk factors for their development and outcomes. Clinical records of 226 consecutive patients with corneal ulcers referred to our tertiary care center were retrospectively evaluated. Frequency, clinical features, and management of toxic corneal ulcers are described. The relationship between clinical severity and outcomes (healing time, corneal transparency, and visual acuity) of toxic corneal ulcers and the number and classes of topical drugs, the number of daily instillations, and the duration of treatment were statistically evaluated. Toxic corneal ulcer was diagnosed in 9% (21/226) of all patients. After topical treatment discontinuation, the cornea spontaneously healed in all patients in 2 to 21 days. A longer healing time was related to a greater number of topical drugs used (p=0.029), a greater frequency of daily instillations (p=0.042), and a longer duration of treatment (p=0.048). The specific drugs used did not significantly influence healing time. After resolution, 16 out of 21 patients showed corneal scarring and impairment of visual function. The severity of corneal haze was related to the number of drugs used (p=0.023), to the frequency of daily instillations (p=0.031), and to the healing time (p=0.008). Toxic corneal ulcer is a frequent disease that can potentially lead to permanent visual impairment. A high-dose regimen is the major risk factor for corneal toxic ulcer development and poor visual outcomes.

    Full Text Available Background and Aim: Antioxidant capacity of betaine has been indicated in our recent studies. Thus, we examined oral betaine as an antioxidant agent in combination with antisecretory drugs to prevent indomethacin-induced gastric damages in rats. Materials and Methods: Fifty-six adult male Sprague–Dawley rats were divided into two controls (negative and normal and five experimental groups as follows: betaine-indomethacin (Bet.-Ind., ascorbic acid-indomethacin (Asc.-Ind., omeprazole-indomethacin (Ome.-Ind., betaine-omeprazole plus indomethacin (Bet.-Ome.-Ind. and betaine-ranitidine plus indomethacin (Bet.-Ran.-Ind.. Results: The betaine pretreated groups received betaine at a dosage of 1.5% (w/w in their diet, whereas 50 mg/kg of ascorbic acid was administered orally to the Asc.-Ind., group for 15 consecutive days. After a 24 hour fast, all the groups received 48 mg/kg of indomethacin once except for normal control group. The omeprazole and ranitidine groups also received one dose of omeprazole (10 mg/kg and ranitidine (50 mg/kg, 120 minutes before receiving indomethacin. Histopathological findings indicated the gastroprotective effects of betaine and ranitidine in pretreated rats. Pretreatment by betaine and ranitidine increased significantly the ulcer index inhibition (%, in comparison with ascorbic acid and omeprazole (alone treatment. Glutathione peroxidase (GPx activity was significantly higher in the Bet.-Ran.-Ind., group as compared to the Asc.-Ind., and Ome.-Ind., treated rats. GPx activity also increased significantly in Bet.-Ind., treated rats as compared to the Asc.-Ind. group. Catalase (CAT activity was remarkably higher in the Bet.-Ran.-Ind., treated rats than the Asc.-Ind., and Ome.-Ind., groups. TBARS concentration as a lipid peroxidation marker increased significantly in Ome.-Ind., group as compared to the Bet.-Ind., and Bet.-Ran.-Ind., treated rats.

    Background and study aims Cameron ulcers are a rare but clinically significant cause of severe upper gastrointestinal hemorrhage (SUGIH). Our aims were to describe (1) the diagnosis, treatment and outcomes of patients with Cameron ulcers causing hospitalization for SUGIH, (2) the differences between patients with occult vs. overt bleeding and (3) between patients treated surgically and medically. Patients and methods Over the past 17 years, all consecutive patients hospitalized in our two tertiary referral medical centers for severe UGIH or severe obscure GIH and entered into our large prospective databasis were screened for Cameron ulcer diagnosis. Results Cameron ulcers were diagnosed in 25 patients of 3960 patients with SUGIH (0.6%). 21 patients had follow-up (median [IQR] time of 20.4 months [8.5–31.8]). Patients were more often elderly females with chronic anemia, always had large hiatal hernias, and were usually referred for obscure SUGIH. Twelve (57.2%) patients were referred to surgery for rebleeding and recurrent blood loss while treated with high dose of proton pump inhibitors (PPI). 9 (42.8%) other patients continued PPI without any rebleeding during the follow-up. Patients with overt bleeding had significantly more prior hospitalizations for SUGIH, more often stigmata of hemorrhage on ulcers, and more red blood cell transfusions than patients with occult bleeding. However, there was no difference in rebleeding and mortality rates between the two groups. Conclusions Cameron ulcers in large hiatal hernias are an uncommon cause of SUGIH. Most of patients are referred for obscure GIH. The choice of medical vs. surgical therapy should be individualized. PMID:23616128

    2012-02-01

    This study investigated the use of a bioactive phytochemical, namely ginger extract (GE), for its antioxidant and antiulcer effects, and also for supporting probiotic growth and activity. Use of probiotics is limited in therapy because of their transience and inability to survive the adverse physiological conditions of the gastrointestinal tract. Packaging probiotics in a suitably designed pharmaceutical system with GE may facilitate their establishment in the stomach mucosa. A probiotic (Lactobacillus acidophilus) and GE were simultaneously and individually encapsulated/immobilized in alginate floating beads. The developed system was evaluated for diameter, buoyancy, entrapment, porosity, in-vitro viability/release and pharmacodynamics in a cold restraint stress induced gastric ulcer model in rats. The developed floating beads stayed in the stomach for more than 10 h and both agents were released slowly and over a prolonged period from these beads. Significant and promising results were obtained for the combination (synbiotic) system in terms of ulcer index, mucus secretion, oxidative stress and histopathological parameters, as compared with the individual agents. The developed system could completely revert the damage induced in ulcerated stomachs at physiological (ulcer index and mucus secretion), biochemical (oxidative stress) and histological levels. This study establishes that suitable packaging of GE and Lactobacillus acidophilus together in floating beads can help exploit their prospects as therapeutic curative agents rather than potential preventive agents. © 2011 The Authors.

  4. Using stool antigen to screen for Helicobacter pylori in immigrants and refugees from high prevalence countries is relatively cost effective in reducing the burden of gastric cancer and peptic ulceration.

    Directory of Open Access Journals (Sweden)

    Thomas R Schulz

    Full Text Available OBJECTIVES: Refugees and immigrants from developing countries settling in industrialised countries have a high prevalence of Helicobacter pylori (H. pylori. Screening these groups for H. pylori and use of eradication therapy to reduce the future burden of gastric cancer and peptic ulcer disease is not currently recommended in most countries. We investigated whether a screening and eradication approach would be cost effective in high prevalence populations. METHODS: Nine different screening and follow-up strategies for asymptomatic immigrants from high H. pylori prevalence areas were compared with the current approach of no screening. Cost effectiveness comparisons assumed population prevalence's of H. pylori of 25%, 50% or 75%. The main outcome measure was the net cost for each cancer prevented for each strategy. Total costs of each strategy and net costs including savings from reductions in ulcers and gastric cancer were also calculated. RESULTS: Stool antigen testing with repeat testing after treatment was the most cost effective approach relative to others, for each prevalence value. The net cost per cancer prevented with this strategy was US$111,800 (assuming 75% prevalence, $132,300 (50% and $193,900 (25%. A test and treat strategy using stool antigen remained relatively cost effective, even when the prevalence was 25%. CONCLUSIONS: H. pylori screening and eradication can be an effective strategy for reducing rates of gastric cancer and peptic ulcers in high prevalence populations and our data suggest that use of stool antigen testing is the most cost effective approach.

    2012-09-25

    In late 2006 an unusual ulcerative condition in wild fish was reported for the first time in Africa from the Chobe and upper Zambezi Rivers in Botswana and Namibia. Concern increased with subsistence fishermen reporting large numbers of ulcerated fish in their catches. In April 2007 the condition was confirmed as an outbreak of epizootic ulcerative syndrome (EUS). The causative agent, Aphanomyces invadans, is a pathogenic water mould of fish that shows little host specificity. Ulcers follow infection of tissues by oomycete zoospores, resulting in a granulomatous inflammation associated with invading oomycete hyphae. Granulomatous tracts surrounding oomycete hyphae within the necrotic tissues characterise the diagnostic histological picture. The upper Zambezi floodplain at the confluence with the Chobe River spans the four countries of Botswana, Namibia, Zambia and Zimbabwe, making disease control a challenge. The floodplain ecosystem supports a high fish diversity of around 80 species, and is an important breeding and nursery ground. The annual cycle of flooding brings about changes in water quality that are thought to favour the infectivity of A. invadans, with diseased fish appearing soon after the plains become flooded. Since 2006 the disease has spread rapidly upstream along the upper Zambezi and its tributaries. By 2010 the disease was reported from the Okavango Delta in Botswana and in 2011 from the Western Cape Province of South Africa. EUS has the potential to disrupt floodplain ecosystems elsewhere in Africa where high fish diversity forms the basis of subsistence fisheries and local economies, and is a direct threat to freshwater fish culture.

    AIM: To describe the epidemiological features of peptic ulcer disease in Wuhan area during 1997-2002, to analyze the sex, age and occupation characteristics, as well as the geographic distribution of peptic ulcer disease, and to determine the effective methods of preventing and controlling peptic ulcer disease. METHODS: In the early 1980s, the peptic ulcer disease registry system was established to collect the data of peptic ulcer disease in Wuhan area. Here we performed a statistically detailed analysis of 4876 cases of peptic ulcer disease during 1997-2002. RESULTS: The morbidity of peptic ulcer disease between males and females was significantly different (χ2 = 337.9, P peptic ulcer diseases were found at the age of 20 to 50 years. Because of different occupations, the incidence of peptic ulcer disease was different in different areas. CONCLUSION: The incidence of peptic ulcer disease is highly associated with sex, age, occupation and geographic environmental factors. By analyzing the epidemiological features of peptic ulcer disease, we can provide the scientific data for prevention and control of peptic ulcer disease. PMID:15484323

    Gastric ulcers are a major problem worldwide with no effective treatment. The objective of this study was to evaluate the use of manuka honey in the treatment of acetic acid-induced chronic gastric ulcers in rats. Different groups of rats were treated with three different concentrations of honey. Stomachs were checked macroscopically for ulcerative lesions in the glandular mucosa and microscopically for histopathological alterations. Treatment with manuka honey significantly reduced the ulcer index and maintained the glycoprotein content. It also reduced the mucosal myeloperoxidase activity, lipid peroxidation (MDA), and the inflammatory cytokines (TNF-α, IL-1β, and IL-6) as compared to untreated control group. In addition, honey-treated groups showed significant increase in enzymatic (GPx and SOD) and nonenzymatic (GSH) antioxidants besides levels of the anti-inflammatory cytokine IL-10. Flow cytometry studies showed that treatment of animals with manuka honey has normalized cell cycle distribution and significantly lowered apoptosis in gastric mucosa. In conclusion, the results indicated that manuka honey is effective in the treatment of chronic ulcer and preservation of mucosal glycoproteins. Its effects are due to its antioxidant and anti-inflammatory properties that resulted in a significant reduction of the gastric mucosal MDA, TNF-α, IL-1β, and IL-6 and caused an elevation in IL-10 levels.

    This study aimed at defining the mortality and the nature of fatal complications that arise out of esophageal ulcer for one clearly defined geographical area. In this national, population-based study, the occurrence of fatal esophageal ulcer or ulcer requiring hospital treatment between January 1987 and December 2000 was assessed by the use of Finland's administrative databases. Medical records provided etiology of fatal ulcer and agonal symptoms. Due to an esophageal ulcer, 2,242 patients received treatment in Finnish hospitals, at an annual frequency of 3.2/100,000. Ulcer with hemorrhage (53.5%), perforation (38.4%), or aspiration pneumonia (2.3%) was the cause of death in 86 patients for an annual mortality of 0.12/100,000. Based on the number of ulcers treated, 3.8% cases ended fatally. Gastroesophageal reflux disease (GERD) seemed to be the etiologic factor for ulcer in 68 (79.0%) patients. The most common agonal symptoms were hematemesis (41.8%), abdominal pain (25.6%), melaena (22.1%), and dyspnea (17.4%). Twenty (23.3%) patients were found dead at home. The rarity of the disease, related disorders, and the diversity of symptoms make the complicated esophageal ulcer a diagnostic challenge. Effective monitored treatment for severe GERD may be an important step to prevent fatal outcome.

    Previous studies demonstrated that the sensitivity of rapid urease test (RUT) for diagnosis of Helicobacter pylori infection decreased during peptic ulcer bleeding. We designed this study and tried to find a better method to improve the detection rate of H. pylori infection at the same session of endoscopic diagnosis of peptic ulcer bleeding. We prospectively enrolled 116 patients with peptic ulcer bleeding. These patients received intravenous proton pump inhibitor and then received upper gastrointestinal endoscopy within 24 h after arrival. We took one piece of biopsy from gastric antrum (Group 1), four pieces from gastric antrum (Group 2), and one piece from the gastric body (Group 3) for three separate RUTs, respectively. (13)C-urease breath test was used as gold standard for diagnosis of H. pylori infection. There were 74 patients (64 %) with positive (13)C-urease breath test. Among these 74 patients, 45 patients had positive RUT (sensitivity: 61 %) in Group 1; 55 patients had positive RUT (sensitivity: 74 %) in Group 2; 54 patients had positive RUT (sensitivity: 73 %) in Group 3. There were significant differences between Group 1 and Group 2 (p = 0.02) and between Group 1 and Group 3 (p = 0.022). The sensitivity of RUT was 61 % during peptic ulcer bleeding. The sensitivity of RUT can be increased significantly by increased biopsy number from gastric antrum or biopsy from gastric body.

    Pharmacological effects of solid dispersions (SDs) of a taurine zinc complex on gastric ulceration and anxiety were investigated. Pretreatment with taurine zinc (50, 100 or 200mg/kg) SDs dose-dependently protected rat gastric mucosa against cold-restraint stress (CRS)-induced gastric injury, and significantly attenuated increases in gastric mucosal H(+)K(+)-ATPase activity and lipid peroxidation and enhanced SOD activity. Taurine zinc also inhibited CRS-induced elevation of the serum stress hormones adrenocorticotropic hormone and corticosterone and upregulated HSP70 expression in the gastric mucosa. Moreover, taurine zinc (200mg/kg) SDs more potently protected the gastric mucosa from ulceration than the same dose of taurine, which may be attributed to a synergistic effect between taurine and zinc. Behavioral experiments in mice showed that taurine zinc SDs significantly increased the number of entries and time spent on the open arms in the elevated plus-maze test, time spent in the central area and total distance traveled in the open field test, and time spent and number of entries into the light compartment in the light/dark box test, indicative of reduced anxiety-like behaviors. This study demonstrates taurine zinc protected the gastric mucosa against CRS-induced gastric damage by decreasing oxidative stress, promoting endogenous HSP70 expression and attenuating psychological stress.

    Helicobacter pylori causes various diseases such as chronic gastritis, peptic ulcer and gastric cancer. While majority of the people infected with H. pylori is asymptomatic, 15-20 % of them develop such diseases. The main factors, which determine the development of H. pylori related diseases might be bacterial virulence, host genetic and environmental factors.The aim of this study was to reveal the factors that play a role in the disease development in patients with reflux esophagitis and peptic ulcer, infected with Helicobacter pylori. Environmental factors such as medical agents, smoking and body mass index were evaluated. The factors specific to bacteria such as vacA, CagA, babA and iceA virulence genotypes and the host factors such as IL-1, IL-2, IL-4, IL-6, IL-10, IL-12, interferon-γ, TNF-α, ve TGF-β1 gene polymorphisms were compared between the two groups.H. pylori infected twenty five patients with reflux esophagitis and peptic ulcer were enrolled in the study. There was no statistical difference between the two groups regarding environmental factors. IL-2 -330T +166T (p=0.037) and IL10 -1082A; -819C (p=0.049) gene polymorphisms were significantly more common in the group of patients with peptic ulcer compared to the group with reflux esophagitis. In both groups of patients, either with reflux esophagitis or peptic ulcer, multiple H. pylori virulence genotypes (cagA, vacA, babA) (mean values 74 %, 78 %, 54 % respectively) were observed.In this study, we revealed that cytokine gene polymorphisms may play a role in the development peptic ulcer while H. pylori virulence genotypes seem to be crucial for the development of associated diseases (Tab. 4, Ref. 51).

    Background/Aims Helicobacter pylori eradication may facilitate the healing of iatrogenic ulcer after endoscopic resection of gastric neoplasm. This study involved designing a randomized, double-blinded, placebo-controlled, multicenter trial, performed by the Korean College of Helicobacter and Upper Gastrointestinal Research and the Medical Research Collaboration Center, Seoul National University Hospital. Methods We intend to enroll up to 232 patients H.-pylori-positive patients who have gastric adenoma or early gastric cancer after endoscopic resection. The enrolled patients are being randomly allocated to the H.-pylori-eradication-plus-proton-pump-inhibitor group or the placebo-plus-proton-pump-inhibitor group based on their histology results and the size of the resected specimen. After random allocation, the iatrogenic ulcer size and stage are evaluated at 4- and 8-week follow-ups (with a window of ±7 days). The primary end point is the healing rate of the ulcer by stage, and the secondary end point is the rate of ulcer size reduction, relief rate from ulcer-related symptoms, and adverse-event rates. Results More than 90% of the target subjects have already been enrolled into the study and are receiving ongoing periodic monitoring by the Medical Research Collaboration Center. Conclusions Completion of the study should reveal whether H. pylori eradication can facilitate the healing of ulcer after endoscopic resection in Korea. PMID:21253301

    Morgellons disease is a psycho-dermatologic condition in which patients report fibers or filaments "growing" out of their skin. This case report highlights an oral ulceration in a young woman associated with Morgellons disease, a condition that has not been previously described in the dental literature. An increasing number of individuals are self-reporting this condition and oral health care providers must be familiar with this disorder. Copyright © 2011 Mosby, Inc. All rights reserved.

    Gastric urease was studied isotopically in 230 patients with biopsy-proven normal mucosa or chronic gastritis, including 59 patients with ulcer disease. Carbon-14-urea was given in 25 ml of water without substrate carrier or nutrient-dense meal, and breath samples were collected over a 60-min period. The amount of 14CO2 excreted at 10 min was independent of the rate of gastric emptying and was not quantitatively influenced by the buccal urease activity. The 10-min 14CO2 values discriminated well between Helicobacter pylori positive and negative patients (94% sensitivity, 89% specificity) and correlated with the number of organisms assessed by histology. The test was a good predictor of chronic gastritis (95% sensitivity and 96% specificity), and a quantitative relationship was observed between 14CO2 values and the severity and activity of the gastritis. In H. pylori positive patients, breath 14CO2 was found to be similar in patients with and without ulcer disease, suggesting that the number of bacteria is not a determining factor for the onset of ulceration

    In the present study, comparative proteomic analysis was performed in rats subjected to water immersion‑restraint stress (WRS). A total of 26 proteins were differentially expressed and identified using matrix‑assisted laser desorption/ionization time of flight mass spectrometry. Among the 26 differentially expressed protein spots identified, 13 proteins were significantly upregulated under WRS, including pyruvate kinase and calreticulin, which may be closely associated with energy metabolism. In addition, 12 proteins were downregulated under WRS, including hemoglobin subunit β‑2 and keratin type II cytoskeletal 8, which may be important in protein metabolism and cell death. Gene Ontology analysis revealed the cellular distribution, molecular function and biological processes of the identified proteins. The mRNA levels of certain differentially expressed proteins were analyzed using fluorescence quantitative polymerase chain reaction analysis. The results of the present study aimed to offer insights into proteins, which are differentially expressed in gastric ulcers in stress, and provide theoretical evidence of a radical cure for gastric ulcers in humans.

    The management of Crohn's disease and ulcerative colitis has become increasingly complex. With the current utilization of immunosuppressive therapies earlier in the disease course for patients presenting with moderate to severe disease, there is a great need for additional biologic agents targeting inflammatory mediators other than anti-tumor necrosis factor-α (anti-TNF) agents. Although anti-TNF agents have positively impacted the treatment of inflammatory bowel disease, many patients can lose their response or develop intolerance to these agents over time through the formation of antidrug antibodies. Furthermore, a sizeable percentage of patients are primary nonresponders to anti-TNF drugs. Vedolizumab (Entyvio, Takeda Pharmaceuticals), a monoclonal antibody to the α4β7 integrin, inhibits gut lymphocyte trafficking and has been demonstrated to be an effective and safe agent for the treatment of both Crohn's disease and ulcerative colitis. This article reviews the clinical trial evidence and rationale for the use of vedolizumab in moderate to severe Crohn's disease and ulcerative colitis.

    Full Text Available Three cases of coexisting ulcerative colitis and Crohn’s disease are presented. In the first case, the patient had a long-standing history of ulcerative proctitis before developing Crohn’s colitis. In the two remaining cases, the patients presented initially with Crohn’s disease of the ileum and, subsequent to resection, developed ulcerative colitis. Well-documented cases of patients diagnosed with both ulcerative colitis and Crohn’s disease are rare. The literature on such cases is reviewed, and the controversy over whether ulcerative colitis and Crohn’s disease are two distinct diseases is explored.

    Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

    Telomerase is a ribonucleoprotein polymerase that is essential for cell immortality. Recent studies have demonstrated that a high percentage of gastric cancer tissue expressed telomerase. This study describes the presence of telomerase activity in gastric lavage fluid in patients with gastric cancer. Gastric lavage fluid was collected during esophageogastroduodenoscopy in 70 patients: 25 with gastric cancer, 25 with peptic ulcer disease, and 20 with normal stomach. The fluid and biopsy samples were analyzed for telomerase activity by a polymerase chain reaction-based telomerase repeat amplification protocol. The findings were related to the histological results. Telomerase activity was present in 24 of the 25 (96%) gastric cancer tissue and in 7 of the 25 tissue specimens from peptic ulcer or gastritis. In the gastric lavage fluid, telomerase was detected in 20 patients (80%) with gastric cancer, 7 patients (28%) with peptic ulcer, and none in normal subjects (P < 0.001). The sensitivity, specificity, positive predictive value, and negative predictive value of gastric fluid telomerase expression in gastric cancer patients was 80%, 84%, 74%, and 88%, respectively. The presence of telomerase activity is present in gastric lavage fluid of patients with gastric cancer as compared to those without, may represent a novel method for diagnosis of gastric cancer.

    Background Peptic ulcer and its treatments have been associated to pancreatic cancer risk, although the evidence is inconsistent. Methods We pooled 10 case–control studies within the Pancreatic Cancer Case–control Consortium (PanC4), including 4717 pancreatic cancer cases and 9374 controls, and estimated summary odds ratios (OR) using multivariable logistic regression models. Results The OR for pancreatic cancer was 1.10 [95% confidence interval (CI) 0.98–1.23] for history of ulcer (OR = 1.08 for gastric and 0.97 for duodenal ulcer). The association was stronger for a diagnosis within 2 years before cancer diagnosis (OR = 2.43 for peptic, 1.75 for gastric, and 1.98 for duodenal ulcer). The OR was 1.53 (95% CI 1.15–2.03) for history of gastrectomy; however, the excess risk was limited to a gastrectomy within 2 years before cancer diagnosis (OR = 6.18, 95% CI 1.82–20.96), while no significant increased risk was observed for longer time since gastrectomy. No associations were observed for pharmacological treatments for ulcer, such as antacids, H2-receptor antagonists, or proton-pump inhibitors. Conclusions This uniquely large collaborative study does not support the hypothesis that peptic ulcer and its treatment materially affect pancreatic cancer risk. The increased risk for short-term history of ulcer and gastrectomy suggests that any such association is due to increased cancer surveillance. PMID:23970016

    Ecabet sodium (ES) is a new non-systemic anti-ulcer agent belonging to the category of gastroprotective agents. In this study we aimed to compare the efficacy of a combination therapy with lansoprazole (LS) followed by ES with LS alone in treating endoscopic submucosal dissection (ESD)-induced iatrogenic gastric ulcers. Patients diagnosed with gastric adenomas or early gastric cancer were randomly divided into either the LS group (30 mg once daily for 4 weeks; n = 45) or the LS + ES group (LS 30 mg once daily for one week followed by ES 1500 mg twice daily for 3 weeks; n = 45). Four weeks after ESD, a follow-up endoscopy was conducted to evaluate the proportions of ulcer reduction and ulcer stages in the two groups. In all, 79 patients were included in the final analyses. Both treatment modalities were well-tolerated in most patients, with a drug compliance of over 80%. There were no significant differences between the two groups in terms of the proportions of ulcer reduction (0.9503 ± 0.1215 in the LS group vs 0.9192 ± 0.0700 in the LS + ES group, P = 0.169) or ulcer stage (P = 0.446). The prevalence of adverse events related to drugs and bleeding were also similar between the two groups. Sequential therapy with LS + ES is as effective as LS alone against ESD-induced gastric ulcers. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

    Stomach carcinoma is more common disease in Korea than western countries. The reported ultrasonographic findings of gastric carcinoma were thickening of gastric wall and 'pseudokidney' sign. The author analyzed ultrasonographic findings of 101 cases with gastric carcinoma who were performed ultrasonography and gastroscopy at Kyung Hee University Hospital from October 1982 to October 1985. The results were as followings; 1. Types of gastric carcinoma were consisted with infiltrative type 68 cases, infiltrative type with ulceration 16 cases, polypoid type with ulceration 1 case, infiltrative adn polypoid type 4 cases, limits plastica type 3 cases, ulcerative type 1 case and polypoid type 1 case. 2. Extent of the lesions were in body and antrum 45 cases, entire stomach 18 cases, antrum 18 cases, body 12 cases, body and fundus 6 cases. 3. Ultrasonography was useful in demonstrating the extent of the tumor and the presence of materials elsewhere in abdomen

    The aim was to examine the influence of different modalities of peptic ulcer surgery on the gastric emptying (GE) pattern and related serum level changes of selected gut hormones. Fifty eight subjects were examined. In 48 of them peptic ulcer surgery was performed at least six months before the examination: Billroth I (B1) in 11, Billroth II (B2) in 16, B1 with the selective vagotomy - Harkins 1 (H1) in 9 and B2 with the selective vagotomy - Harkins 2 (H2) in 12. Ten healthy volunteers (C) were also examined. The results of gastric emptying showed that the lag phase duration was inversely related to the GE rates, and the GE pattern was linear in both controls (C) and in operated patients, except in B2 group, in which the GE pattern was exponential. In comparison with C group, GE was slower in B1, H1 and H2 groups, and faster in B2 group. The plasma gastrin values in C group, showing two peaks, were higher in relation to other groups. In relation to C group, higher values of motilyn were obtained in patients after the selective vagotomy. The plasma somatostatin values recorded in B1 and H1 groups, showing the marked peaks, were higher in relation to C group. In relation to C group the highest plasma neurotensin values were obtained in B2 group. In order to understand entirely the influence of peptic ulcer surgery on the GI function, further research of the role of specific hormones and neuropeptides is needed, which would enable more precise selection of the therapy in order to prevent postvagotomy and postgastrectomy syndromes.

    Peptic ulcer disease can lead to serious complications including massive hemorrhage or bowel perforation. The modern treatment of peptic ulcer disease has transitioned from the control of gastric acid secretion to include antibiotic therapy in light of the identification of Helicobacter pylori as a causative infectious organism. We sought to determine trends related to this discovery by using a national database. Patient discharges with peptic ulcer disease and associated sequelae were queried from the Nationwide Inpatient Sample, 1993 to 2007, under the auspices of a data user agreement. To account for the Nationwide Inpatient Sample weighting schema, design-adjusted analyses were used. Standard error was calculated using SUDAAN software (Research Triangle International, NC, USA). Decreases in the incidences of gastrointestinal perforation, gastrointestinal hemorrhage, and surgical procedures most specific to peptic ulcer disease were statistically significant over the study period [range of P value (two tailed) = 0.000 - 0.00353; significant at P peptic ulcer disease has revolutionized the understanding and management of the disease. Medical conditions and surgical procedures associated with end-stage peptic ulcer disease have significantly decreased according to analysis of selected index categories. Resident physician education objectives may need to be modified in light of these trends. REVIEW CRITERIA: We reviewed patients with peptic ulcer disease. The database used was the Nationwide Inpatient Sample, 1993 to 2007. MESSAGE FOR THE CLINIC: Medical therapy has resulted in decreased morbidity from H. pylori infection as it is the causative agent in the majority of peptic ulcer disease. Aggressive screening and treatment of this infection will lead to further reduction in morbidity.

    Peptic ulcer disease is one of the most commonly encountered diseases in gastroenterology clinics. After the discovery of Helicobacter pylori by Warren and Marshall, it has been identified as the most important cause of peptic ulcer. Eradication of H. pylori markedly reduces the post-treatment recurrence rate of peptic ulcer. However, as human populations age, the incidence of cardiovascular and musculoskeletal diseases increases and consequent use of aspirin and non-steroidal anti-in-flammatory drugs increases. Thus causes and presenting patterns of peptic ulcer have changed. In this review, I describe new diagnostic and therapeutic strategies for peptic ulcer disease and explore future perspectives.

    This study tested the hypothesis that adrenocortical function would be altered in horses with equine gastric ulcer syndrome (EGUS). Twenty-six sport horses competing at national or international levels in eventing (n=15) or endurance (n=11) were subjected to a gastroscopic examination and an adrenocorticotropic hormone (ACTH) stimulation test. Salivary cortisol concentrations were measured before (baseline) and after (30, 60, 90, 120 and 150min) IV ACTH injection (1μg/kg bodyweight). Within EGUS, two distinct diseases, equine squamous gastric disease (ESGD) and equine glandular gastric disease (EGGD), can be distinguished. ESGD was diagnosed in 8/11 (73%; 95% confidence intervals [95%CI], 43-92%) endurance horses and 5/15 (33%; 95% CI, 14-58%) eventing horses. EGGD was observed in 9/11 (82%; 95% CI, 53-96%) endurance horses and 9/15 (60%; 95% CI, 35-81%) eventing horses. The presence or severity of ESGD was unrelated to the presence or severity of EGGD. ACTH stimulation induced a larger increase in cortisol concentration in horses with moderate EGGD than in horses with mild EGGD. Cortisol concentration during the entire sampling period (total increase in cortisol concentration during the entire sampling period [dAUC], 31.1±6.4ng/mL) and the highest measured concentration at a single time point (maximal increase in cortisol concentration [dMAX], 10.3±2.3ng/mL) were increased (P=0.005 and P=0.038, respectively), indicating that horses with glandular gastric disease exhibited increased adrenocortical responses to ACTH stimulation. These results suggest that EGGD might be associated with an enhanced adrenocortical sensitivity. Further investigations are warranted to confirm the association between adrenocortical sensitivity and EGGD and to elucidate the pathophysiological mechanisms involved. Copyright © 2017 Elsevier Ltd.

    This chapter explains the procedure of ethanol-induced ulcer to check the protective effect of drugs over induced ulcer in rats. Ulcer is defined as the erosion in the lining of the stomach or duodenum and is caused by the disruptions of the gastric mucosal defence and repair systems. Ulceration of stomach is called gastric ulcer and that of duodenum is called duodenal ulcer and together peptic ulcer. In clinical practice, peptic ulcer is one of the most prevalent gastrointestinal disorders, which commonly occurs in developed countries.

    Abstract Background: Increasingly, studies have focused on the relationship between Helicobacter pylori (H pylori) cytotoxin associated gene A protein (CagA) Glu-Pro-Ile-Tyr-Ala (EPIYA)-D motifs or multiple EPIYA-C phosphorylation sites and peptic ulcer disease (PUD) or gastric cancer (GC) risk. However, the conclusions have been inconsistent. The aim of this meta-analysis was to evaluate whether 1 CagA EPIYA-D motif or multiple EPIYA-C phosphorylation sites were associated with PUD or GC risk. Materials and methods: A literature search was performed in PubMed, Web of Science, Wanfang Data, Excerpt Medica Database, and the Chinese National Knowledge Infrastructure database to identify eligible research. We analyzed the odds ratios (OR) and 95% confidence intervals (CI) to assess the strength of association. Results: Compared with 1 EPIYA-C motif in Asian populations, 1 EPIYA-D site was associated with an increased GC risk (OR=1.91, 95% CI=1.19–3.07, P = .008). However, 1 EPIYA-D motif was not significantly associated with PUD (OR = 0.90, 95% CI = 0.46–1.76, P = .764), gastric ulcer (GU) (OR = 0.85, 95% CI = 0.27–2.63, P = .771), or duodenal ulcer (DU) (OR = 0.89, 95% CI = 0.25–3.16, P = .859) risk. Compared with no more than 1 EPIYA-C motif, multiple motifs were associated with increased PUD (OR = 2.33, 95% CI = 1.29–4.20, P = .005) and DU (OR = 2.32, 95% CI = 1.08–5.00, P = .031) risk in Asia and GC risk in the United States and Europe (OR = 3.28, 95% CI = 2.32–4.64, P detection of polymorphic CagA EPIYA motifs may improve clinical prediction of disease risk.

    The healing activity of black tea (BT) and BT fermented with Candida parapsilosis and kombucha culture, designated as CT and KT respectively against the indomethacin-induced stomach ulceration has been studied in a mouse model. The KT sample (KT4) produced by fermenting BT for four days, showed the best DPPH radical scavenging capacity and phenolics contents. Hence the ulcer-healing activity of KT4 was compared with those of CT4 and BT. All the tea extracts (15 mg kg(-1)) could effectively heal the gastric ulceration as revealed from the histopathological and biochemical studies, with relative efficacy as KT4 > CT4 ∼ BT. The healing capacities of the tea extracts could be attributed to their antioxidant activity as well as the ability to protect the mucin content of the gastric tissues. In addition, the ability of KT4 to reduce gastric acid secretion might also contribute to its ulcer-healing activity. The tea preparation KT4 (15 mg kg(-1)) was as effective as the positive control, omeprazole (3 mg kg(-1)) in ulcer healing.

    About 60-70% of Helicobacter pylori strains possess cagA (cytotoxin associated gene A) gene and express its product CagA, a highly immunogenic 128-140 kD protein. Patients infected with CagA positive strains develop serum IgG anti-CagA. A serologic response to CagA has been detected in Helicobacter pylori infected patients with peptic ulcer more frequently than in those with gastritis alone. It is nuclear whether this finding is consistent in different geographical populations. We investigated the relationship between anti-CagA seropositivity and peptic ulcer disease in a Northern Italian population. We studied 135 H. pylori infected patients: 65 with duodenal ulcer (DU), 28 with gastric ulcer (GU) and 42 with non ulcer dyspepsia (NUD). Sera from these patients were assayed by EIA (enzyme immunoassay) for anti-CagA IgG. A high prevalence of anti-CagA was found associated with DU (86.1%) and GU (96.4%), while NUD patients showed anti-CagA seropositivity of 52.4% (Odd ratio, 5.66; 95% confidence interval, 2.23 to 14.32; p peptic ulcer disease and suggest that CagA might play an important role in ulcer pathogenesis.

    Helicobacter pylori (H. pylori) infection induces inflammation of the gastric mucosa, which may progress to precancerous lesions leading to gastric cancer. Pathological determinism is associated to some virulence genes of the bacterium, notably the vacA and cagA genes. The present study aimed to determine the H. pylori genotypes distribution and their association with sex, age and gastric diseases in a Moroccan population. Gastric biopsy was taken from 1079 consenting patients. The specimens ...

    Full Text Available We analyzed the clinical and endoscopic features of H.pylori-associated peptic ulcer disease in children. Prevalence of H.pylori-positive cases of peptic ulcer disease, regardless of the localization of ulcers, was determined. Toxigenic strains of H.pylori cause severe course of ulcer disease with prolonged and frequent relapses. Most of H.pylori-positive lesions are associated with Cag+-VacA+ serotype of microorganism. In individuals infected with serotype CagA-VacA+, ulcers of large sizes are more common.

    To clarify blood calcium concentrations (BCCs) as an indicator of the functional state of the calcium-regulating system in the concomitant course of recurrent peptic ulcer disease (PUD) and hypertension, by comparing with the severity of a ulcerous process, with changes in regional microcirculation, and with the functions of the stomach. To elucidate the pathogenetic justification for and clinical efficacy of slow calcium channel blockers (SCCBs) in the treatment of this comorbidity. In the case-control study, each patient with recurrent PUD and grade 1, Stage I hypertension (Group 1; n=23) corresponded to a recurrent PUD patient matched for sex, age, and ulcer site (Group 2, n=23). The complex of treatment for these patients included the SCCB nifedipine. A control group consisted of 56 recurrent PUD patients who received combination therapy without nifedipine. All the patients over time underwent clinical and endoscopic examinations and determinations of BCCs, indicators of gastric secretory and motor functions, and regional microcirculation in the gastroduodenal mucosal biopsy specimens. Recurrent PUD was present with a reliable BCC increase that was more substantial when it was associated with hypertension. Calcium imbalance was accompanied by changes in regional microcirculation and gastric secretory and motor functional indicators forming an acid peptic factor, as well as by hypermotor dyskinesia, which were more pronounced in patients with comorbidity. Incorporation of a SCCB into a complex of therapy for recurrent PUD to eliminate the pathogenic effect of blood calcium contributed to more rapid arrest of the clinical symptoms of a recurrence, to elimination of acute-phase microcirculatory disorders in the gastroduodenal zone, and to the recovery of gastric functional indicators. Elevated blood pressure was ruled out during the therapy of concomitant diseases. Incorporation of a SCCB into the combination therapy of recurrent PUD associated with hypertension

    The purpose of our investigative work has been to determine whether there can be therapeutic roles in the administration of sildenafil citrate, heparin and several neuropeptides on an animal model where gastric ulcers were induced with acetic acid, and to compare their efficacy. The animals were divided into 13 groups, with 4 animals in each. Gastric ulcers was induced in the animals of 12 groups with one untreated group being left as the control (Group I - control; given normal saline (NS)). The other groups were: Group II (ulcer+NS); Group III (5mg/kg sildenafil citrate, low dose); Group IV (10mg/kg sildenafil citrate, high dose); Group V (0.6mg/kg heparin, low dose); Group VI (6mg/kg heparin, high dose); Group VII (20nmol/kg des-acyl ghrelin); Group VIII (40nmol/kg des-acyl ghrelin); Group IX (4nmol/kg acyl ghrelin); Group X (8nmol/kg acly ghrelin); Group XI (20pmol/kg Nesfatin-1); Group XII (15nmol/kg Obestatin) and Group XIII (5nmol/kg Neuropeptide Y). Gastric neuropeptide expression was measured using an immunohistochemical method, and the amount in circulation was detected using ELISA. To compare with no treatment, the controls and other treatment groups, we recorded loss of the surface epithelium of the stomach, erosion, bleeding and inflammatory cell infiltration in the upper halves of the gastric glands. The muscularis and the layers beneath it were, however, apparently normal. The gastric mucosa healed with little or no inflammation when sildenafil citrate, low dose heparin, ghrelin, NUCB2/Nesfatin-1, obestatin, Neuropeptide Y were administered. Overall the data indicate that low dose heparin, and especially sildenafil citrate and neuropeptides, can be used clinically as an alternative approach in the treatment of the gastric ulcer.

The first symptoms of ulcerative colitis occured at the age of eleven, since when the patient has been conservatively treated several times because of the exacerbations of the desease. During control examinations presence of polipoid changes in stomach was discovered by upper endoscopy. Gastrectomy was suggested because the patient had excessive anemic syndrome which required weekly substitutional therapy with deplasmatic eritrocytes, as well as hypoproteinemia, while multiple polipoid changes suspect for malignancy were gastroscopically identifided. Patient accepted surgical treatment, and was transfered to the Clinic of Surgery. Total gastrectomy was performed, and patohystological finding confirmed Ménétrier's desease. After two weeks, the patient was released from the hospital in good general condition, with regular clinical and laboratory findings.

    Although the global prevalence of peptic ulcer disease (PUD) is decreasing, PUD is still one of the most common upper gastrointestinal diseases in the world due to Helicobacter pylori infection and increased use of non-steroidal anti-inflammatory drugs. In Korea, the prevalence of H. pylori infection is also declining, but it is still the major cause of PUD. The outcomes of H. pylori infection are caused by imbalances between bacterial virulence factors, host factors, and environmental influences. In this review, we describe the prevalence trends of H. pylori infection in Korea, the mechanism of H. pylori infection-related PUD, and treatment strategies.

    Full Text Available BACKGROUND: "Helicobacter (H. heilmannii" type 1 is the most prevalent gastric non-H. pylori Helicobacter species in humans suffering from gastric disease. It has been shown to be identical to H. suis, a bacterium which is mainly associated with pigs. To obtain better insights into the long-term pathogenesis of infections with this micro-organism, experimental infections were carried out in different rodent models. METHODOLOGY/PRINCIPAL FINDINGS: Mongolian gerbils and mice of two strains (BALB/c and C57BL/6 were infected with H. suis and sacrificed at 3 weeks, 9 weeks and 8 months after infection. Gastric tissue samples were collected for PCR analysis, histological and ultrastructural examination. In gerbils, bacteria mainly colonized the antrum and a narrow zone in the fundus near the forestomach/stomach transition zone. In both mice strains, bacteria colonized the entire glandular stomach. Colonization with H. suis was associated with necrosis of parietal cells in all three animal strains. From 9 weeks after infection onwards, an increased proliferation rate of mucosal epithelial cells was detected in the stomach regions colonized with H. suis. Most gerbils showed a marked lymphocytic infiltration in the antrum and in the forestomach/stomach transition zone, becoming more pronounced in the course of time. At 8 months post infection, severe destruction of the normal antral architecture at the inflamed sites and development of mucosa-associated lymphoid tissue (MALT lymphoma-like lesions were observed in some gerbils. In mice, the inflammatory response was less pronounced than in gerbils, consisting mainly of mononuclear cell infiltration and being most severe in the fundus. CONCLUSIONS/SIGNIFICANCE: H. suis causes death of parietal cells, epithelial cell hyperproliferation and severe inflammation in mice and Mongolian gerbil models of human gastric disease. Moreover, MALT lymphoma-like lesions were induced in H. suis-infected Mongolian gerbils

    Yoshihisa Sakaguchi

    2010-01-01

    Full Text Available This paper documents the first case of gastric cancer associated with Recklinghausen's disease, which was successfully treated by a totally laparoscopic operation. A 67-year-old woman with Recklinghausen's disease was referred to this department to undergo surgical treatment for early gastric cancer. The physical examination showed multiple cutaneous neurofibromas throughout the body surface, which made an upper abdominal incision impossible. Laparoscopic surgery requiring only small incisions was well indicated, and a totally laparoscopic distal gastrectomy with lymph node dissection was performed. Billroth I reconstruction was done intra-abdominally using a delta-shaped anastomosis. The patient followed a satisfactory postoperative course with no complications. Since the totally laparoscopic gastrectomy has many advantages over open surgery, it should therefore be preferentially used as a less invasive treatment in the field of gastric cancer.

    Duodenal stump insufficiency after surgery for penetrating gastroduodenal ulcer is associated with substantial mortality. "Classical" technique of closing a difficult duodenal stump (Nissen-Bsteh) has, up to now, not been compared with duodenojejunostomy (DJ) in larger patient sets. This also refers to the potential benefit of a gastric and biliary diversion under such conditions. The aim of the present study was to compare classical duodenal closure (CC) with DJ and to evaluate the impact of gastric and biliary diversion on postoperative outcome after surgery for penetrating, high-risk duodenal ulcer in a matched control study. Out of 321 patients, treated for penetrating duodenal ulcer disease, the perioperative outcome of 62 DJ patients was compared with 62 patients undergoing CC matched for age, gender, biliary diversion, and the operating surgeon collective.

    Diseases of the stomach, including gastric cancer and peptic ulcer, are the most common digestive diseases. It is impossible to visualize the entire stomach with the passive capsule currently used in practice because of the large size of the gastric cavity. A magnetically controlled capsule endoscopy (MCE) system has been designed to explore the stomach. We performed a prospective study to compare the accuracy of detection of gastric focal lesions by MCE vs conventional gastroscopy (the standard method). We performed a multicenter blinded study comparing MCE with conventional gastroscopy in 350 patients (mean age, 46.6 y), with upper abdominal complaints scheduled to undergo gastroscopy at a tertiary center in China from August 2014 through December 2014. All patients underwent MCE, followed by conventional gastroscopy 2 hours later, without sedation. We calculated the sensitivity, specificity, positive predictive value, and negative predictive value of detection of gastric focal lesions by MCE, using gastroscopy as the standard. MCE detected gastric focal lesions in the whole stomach with 90.4% sensitivity (95% confidence interval [CI], 84.7%-96.1%), 94.7% specificity (95% CI, 91.9%-97.5%), a positive predictive value of 87.9% (95% CI, 81.7%-94.0%), a negative predictive value of 95.9% (95% CI, 93.4%-98.4%), and 93.4% accuracy (95% CI, 90.83%-96.02%). MCE detected focal lesions in the upper stomach (cardia, fundus, and body) with 90.2% sensitivity (95% CI, 82.0%-98.4%) and 96.7% specificity (95% CI, 94.4%-98.9%). MCE detected focal lesions in the lower stomach (angulus, antrum, and pylorus) with 90.6% sensitivity (95% CI, 82.7%-98.4%) and 97.9% specificity (95% CI, 96.1%-99.7%). MCE detected 1 advanced gastric carcinoma, 2 malignant lymphomas, and 1 early stage gastric tumor. MCE did not miss any lesions of significance (including tumors or large ulcers). Among the 350 patients, 5 reported 9 adverse events (1.4%) and 335 preferred MCE over gastroscopy (95

    Background The study was carried out to determine the cytotoxic, antioxidant and gastro-protective effect of ethyl-4-[(3,5-di-tert-butyl-2-hydroxybenzylid ene)amino] benzoate (ETHAB) in rats. Methodology/Principal Findings The cytotoxic effect of ETHAB was assessed using a MTT cleavage assay on a WRL68 cell line, while its antioxidant activity was evaluated in vitro. In the anti-ulcer study, rats were divided into six groups. Group 1 and group 2 received 10% Tween 20 (vehicle). Group 3 received 20 mg/kg Omeprazole. Groups 4, 5 and 6 received ETHAB at doses of 5, 10, and 20 mg/kg, respectively. After an hour, group 1 received the vehicle. Groups 2–6 received absolute ethanol to induce gastric mucosal lesions. In the WRL68 cell line, an IC50 of more than 100 µg/mL was observed. ETHAB results showed antioxidant activity in the DPPH, FRAP, nitric oxide and metal chelating assays. There was no acute toxicity even at the highest dosage (1000 mg/kg). Microscopy showed that rats pretreated with ETHAB revealed protection of gastric mucosa as ascertained by significant increases in superoxide dismutase (SOD), pH level, mucus secretion, reduced gastric lesions, malondialdehyde (MDA) level and remarkable flattened gastric mucosa. Histologically, pretreatment with ETHAB resulted in comparatively better gastric protection, due to reduction of submucosal edema with leucocyte infiltration. PAS staining showed increased intensity in uptake of Alcian blue. In terms of immunohistochemistry, ETHAB showed down-expression of Bax proteins and over-expression of Hsp70 proteins. Conclusion/Significance The gastroprotective effect of ETHAB may be attributed to antioxidant activity, increased gastric wall mucus, pH level of gastric contents, SOD activity, decrease in MDA level, ulcer area, flattening of gastric mucosa, reduction of edema and leucocyte infiltration of the submucosal layer, increased PAS staining, up-regulation of Hsp70 protein and suppressed expression of Bax.

    Background and Aims: Disease extent in ulcerative colitis [UC] is dynamic and can progress over time. Little is known about risk factors for UC extension in the era of biologics. We investigated the risk of UC extension and subsequent risk of surgery in a Danish population-based cohort. Methods......: All incident UC cases in a strictly defined Copenhagen area between 2003 and 2004 were followed prospectively through 2011. Disease extension was defined as patients with limited UC [E1 or E2] at diagnosis having progressed from the initial extent by colonoscopy or surgery to E2 or extensive colitis...... experienced disease extension. Only extent at diagnosis was a clinical predictor for disease extension. The risk of colectomy was increased in former smokers and patients who progressed to extensive colitis. This highlights the need to prevent disease progression in patients with limited UC, and to identify...

    Gastromalacia is the acute autolytic erosion of the gastric wall. It generally occurs postmortem, and it appears as a slimy brownish black region of the wall which occurs principally in the gastric fundus. A 59-year-old woman died in the Emergency Department following a 2-day period of mild abdominal pain, vomiting, and diarrhea. A forensic autopsy was performed which revealed a rupture of the gastric fundus that had caused leakage of gastric content into the abdominal cavity. There was no macroscopic evidence of peritonitis, and the stomach wall adjacent to the rupture site showed marked thinning. The gross appearance was typical of gastromalacia. In contrast, histological observations revealed the presence of an ulcer at the site of perforation and a severe acute inflammatory reaction indicating a robust reaction with an antemortem rupture. © 2014 American Academy of Forensic Sciences.

    The Helicobacter heilmannii sensu lato (H. heilmannii s.l.) group consists of long, spiral-shaped bacteria naturally colonizing the stomach of animals. Moreover, bacteria belonging to this group have been observed in 0.2-6% of human gastric biopsy specimens, and associations have been made with the development of chronic gastritis, peptic ulceration, and gastric MALT lymphoma in humans. To gain insight into the prevalence of H. heilmannii s.l. infections in patients suffering from gastric disease in China, H. heilmannii s.l. species-specific PCRs were performed on DNA extracts from rapid urease test (RUT)-positive gastric biopsies from 1517 patients followed by nucleotide sequencing. At the same time, Helicobacter pylori cultivation and specific PCR was performed to assess H. pylori infection in these patients. In total, H. heilmannii s.l. infection was detected in 11.87% (178/1499) of H. pylori-positive patients. The prevalence of H. suis, H. felis, H. bizzozeronii, H. heilmannii sensu stricto (s.s.), and H. salomonis in the patients was 6.94%, 2.20%, 0.13%, 0.07%, and 2.54%, respectively. Results revealed that all patients with H. heilmannii s.l. infection were co-infected with H. pylori, and some patients were co-infected with more than two different Helicobacter species. Helicobacter heilmannii s.l. infections are fairly common in Chinese patients. This should be kept in mind when diagnosing the cause of gastric pathologies in patients. Helicobacter suis was shown to be by far the most prevalent H. heilmannii s.l.species. © 2014 John Wiley & Sons Ltd.

    CagA of Helicobacter pylori undergoes tyrosine phosphorylation in a region containing differing numbers of repeat sequences (EPIYAs), which can result in a modulation of the inflammatory response. This study investigated whether the presence of CagA EPIYA variations in strains of H. pylori that are positive for this region contributes to differing degrees of disease severity in the gastric mucosa. In this study, 157 H. pylori-positive patients were included, and of those, 40.8% (64/157) were infected with cagA-positive strains, which were assayed for the presence of CagA EPIYA-ABC, EPIYA-ABCC, and EPIYA-ABCCC. Peptic ulcers were significantly more prevalent in patients infected with strains containing CagA EPIYA-ABCC/ABCCC than in those with CagA EPIYA ABC strains (P=0.044). This suggests that the number of repetitions of EPIYA-C influences the development of gastroduodenal lesions, highlighting the importance and usefulness of evaluating the cagA gene sequence when making therapeutic intervention decisions in patients infected with H. pylori.

    Full Text Available Chronic gastritis and gastric ulcers are prevalent throughout the world and are considered to be a global health problem. Modified Xiaochaihutang (MXCHT prescription is broadly used in traditional medicine hospital for the treatment of gastritis. In order to assess the anti-Helicobacter pylori (H. pylori effect of MXCHT, agar diffusion method in vitro and fluid dilution method for the minimal inhibitory concentration (MIC were established. The anti-inflammatory effects were then evaluated using mouse ear edema model and rat paw edema model. The ethanol-induced gastric ulcer method was employed to verify the gastroprotective effect of active extracts in MXCHT. HPLC-TOF-MS/MS was used for analyzing the possible active constituents after oral administration of effective extracts in ethanol-induced gastric ulcer models. MXCHT and 4 different extracts of the bacterial inhibition diameter and MIC were dramatically decreased compared with control group, showing anti-Helicobacter pylori effects. High dose groups of MXCHT, water extract, EtOAc extract, and n-BuOH extract displayed significant anti-inflammatory effects in xylene-induced mouse ear edema model and carrageenan-induced rat paw edema model test. MXCHT and all active extracts exhibited gastroprotective activity and prevented gastric lesions induced by ethanol in rats. 4 prototype components and 4 metabolites were identified after oral administration of EtOAc extract. In addition, 6 prototype components and 6 metabolites were identified in n-BuOH extract. MXCHT, EtOAc extract, and n-BuOH extract demonstrate gastroprotective effects through anti-Helicobacter pylori and anti-inflammatory activities. Thus, this prescription may be a suitable natural source for the prevention and treatment of chronic gastritis and gastric ulcers.

    The histological material of 158 Billroth II gastrectomy specimens, used for a former study that established a relationship between duodenal ulcers and the presence of gastric metaplastic epithelium in the duodenal bulb, was reinvestigated for the presence of Helicobacter pylori. The results show that in all duodenal ulcer patients with gastric mucin cell metaplasia H. pylori colonized the metaplastic epithelium accompanied by an inflammatory response. The intestinal mucosa was always negative for H. pylori. H. pylori-positive patients also had the micro-organism in their gastric antrum. The results further support the hypothesis that infection of gastric mucosa in the bulb by H. pylori underlies duodenal ulcer disease.

    Ethanol is a psychoactive substance highly consumed around the world whose health problems include gastric lesions. Baccharis trimera is used in folk medicine for the treatment of gastrointestinal disorders. However, few studies have evaluated its biological and toxic effects. To validate the popular use of B. trimera and elucidate its possible antiulcerogenic and cytotoxic mechanisms, a hydroethanolic extract of B. trimera (HEBT) was evaluated in models of gastric lesions. Rats and mice were used to evaluate the protective and antiulcerogenic effects of HEBT on gastric lesions induced by ethanol, acetic acid, and chronic ethanol consumption. The effects of HEBT were also evaluated in a pylorus ligature model and on gastrointestinal motility. The LD50 of HEBT in mice was additionally estimated. HEBT was analyzed by nuclear magnetic resonance, and a high-performance liquid chromatography fingerprint analysis was performed. Oral HEBT administration significantly reduced the lesion area and the oxidative stress induced by acute and chronic ethanol consumption. However, HEBT did not protect against gastric wall mucus depletion and did not alter gastric secretory volume, pH, or total acidity in the pylorus ligature model. Histologically, HEBT accelerated the healing of chronic gastric ulcers in rats, reflected by contractions of the ulcer base. Flavonoids and caffeoylquinic acids were detected in HEBT, which likely contributed to the therapeutic efficacy of HEBT, preventing or reversing ethanol- and acetic acid-induced ulcers, respectively. HEBT antiulcerogenic activity may be partially attributable to the inhibition of free radical generation and subsequent prevention of lipid peroxidation. Our results indicate that HEBT has both gastroprotective and curative activity in animal models, with no toxicity.

    The fundamental pathogenesis of Behçet disease (BD) is still unclear and controversial. Many cases of oral aphthous ulcers and genital ulcers related to BD are reported; nevertheless, idiopathic giant esophageal ulcers related to BD are rare. A rare case for esophageal ulcers related to BD is presented. In China, BD is represented with esophageal involvement which is called esophageal BD (EBD). A 56-year-old man diagnosed to the Gastroenterology Department of Integrated Traditional Chinese and Western Medicine Hospital, for multiple discrete, elliptical esophageal ulcers related to BD. The esophageal ulcers were treated with corticosteroid treatment for 12 weeks. The esophageal ulcers were cured. Our report might give further strength to avoiding the erroneous diagnosis or missed diagnosis for EBD, which is different from esophageal carcinoma, esophageal tuberculosis and esophageal Crohns disease.

    Sole ulcers and white line disease are 2 of the most common claw horn lesions in confined dairy cattle. Predisposing causes include unbalanced weight bearing, and metabolic, enzymatic, and hormonal changes. The white line serves as the junction between the sole and axial and abaxial wall. It is vulnerable to trauma and separation, permitting organic matter to become entrapped. Colonization contributes to retrograde movement of the infection to the solar and perioplic corium, where an abscess forms resulting in pain and lameness. Successful treatment requires an orthopedic foot block to the healthy claw and corrective trimming of the lesion. Copyright © 2017 Elsevier Inc. All rights reserved.

    Native, intact (TrPP) and modified, low-molecular-weight (MTrPP) forms of pectic polysaccharides isolated from turmeric were evaluated for ulcer-preventive potentials in in vitro and in vivo models. Data indicated that MTrPP possessed significantly better ulcer-preventive property than TrPP; inhibiting ulcer scores up to 85%. Results were substantiated by effective muco-protection, H(+),K(+)-ATPase down-regulation, inhibition of H. pylori growth/adherence, higher antioxidant/cytoprotective mechanisms. Structural data indicated TrPP and MTrPP differ in their molecular weights and structural characteristics with different sugar compositions and side chain ratios. MTrPP was rich in galacturonic acid (687mg/g; TrPP-544mg/g) and galactose (52.9%; TrPP-21.7%). Results were substantiated by NMR/FTIR data indicating the presence of homogalacturonan and rhamnogalacturonam-I containing galactans. By virtue of binding to inflammatory marker (galectin-3), galactans may reduce inflammation induced ulcerations. The low molecular weight of MTrPP (155kDa; TrPP-13kDa) may increase its bioavailability than TrPP, thus MTrPP may possess higher antiulcer potential. Copyright © 2015 Elsevier Ltd.

    To report a case of bilateral chronic peripheral ulcerative keratitis secondary to cat-scratch disease. Case report. A 66-year-old woman was initially diagnosed with Perinaud oculoglandular syndrome in her right eye. She subsequently experienced recurrent episodes of bilateral peripheral ulcerative keratitis associated with diffuse thinning, neovascularization, and conjunctivalization of the peripheral corneas. This case report shows a sequential occurrence of bilateral chronic peripheral ulcerative keratitis after an episode of cat-scratch disease. Cat-scratch disease should be included in the differential diagnosis of bilateral chronic peripheral ulcerative keratitis.

    In the expanded indications for endoscopic resection, Japanese guidelines for gastric cancer include differentiated cancers confined to the mucosa with an ulcer ulcer. The horizontal and vertical margins were negative for the tumor. We diagnosed thiscase as curative resection of expanded indication and followed this patient with endoscopy, abdominal ultrasonography (AUS) or enhanced computed tomography (CT) approximately every 6 months. After 17 months, lymph node metastasis was detected with AUS and CT and diagnosed by endoscopic ultrasound-guided fine-needle aspiration biopsy in August 2011. Distal gastrectomy with D2 dissection was carried out in December 2011. Although it is low, the possibility of recurrence should be borne in mind after endoscopic treatment of early gastric cancer, despite its inclusion in the expanded indications for endoscopic resection. © 2014 The Authors.

    Hymenaea stigonocarpa Mart. ex Hayne (Fabaceae) is a medicinal species commonly found in the Brazilian savannah. The stem bark of this medicinal plant, popularly known as "jatobá-do-cerrado", is widely used in tea form to treat gastric pain, ulcers, diarrhoea and inflammation, whereas its fruits pulp is edible. The aim of this study was to investigate the antidiarrheal and anti-ulcer effects of a methanolic extract derived from the stem bark (MHs) and diet with fruit pulp of H. stigonocarpa. The antidiarrheal action of MHs was measured against the intestinal motility and diarrhoea induced by castor oil in mice. The preventive action of MHs (50, 100, 150 and 200mg/Kg, by oral route (p.o.)) against peptic ulcers was evaluated in experimental rodent models challenged with absolute ethanol, non-steroidal anti-inflammatory drugs (NSAIDs), ischemia-reperfusion (I/R) (200mg/Kg, p.o.) and cysteamine (200mg/Kg, p.o.). The main anti-ulcer mechanisms of action of MHs were analysed as follows: evaluation of the gastric juice parameters, assessment of mucus adherence to the gastric wall, determination of the role of nitric oxide (NO) and sulfhydryl compounds (SH), glutathione (GSH) levels and myeloperoxidase (MPO) activity. The healing effects from MHs (200mg/Kg) and diet with fruit pulp (10%) against gastric and duodenal ulcers induced by acetic acid were also evaluated by treating rats over 7 or 14 consecutive days of treatment. The phytochemical profile of MHs and fruit pulp indicated the presence of phenolic compounds (mainly flavonoids and condensed tannins). MHs (200mg/Kg, p.o.) displayed an antidiarrheal effect and were able to protect gastric mucosa against absolute ethanol (68% protection) and also against the injurious effect of NSAIDs (86% protection) when compared to the group treated with vehicle. These results were accompanied by the prevention of GSH depletion and an inhibition of MPO activity when compared to animals treated with vehicle (P<0.05). MHs markedly

    Studying of nitric oxide (NO) dependent mechanisms of regulation of microcirculation in a stomach can provide important diagnostic markers of the development of stress-induced ulcer bleedings. In this work we use a multiscale analysis based on the discrete wavelet-transform to characterize a latent stage of illness formation in rats. A higher sensitivity of stomach vessels to the NO-level in ill rats is discussed.

    To clarify the effect of γδ T cells and invariant Natural Killer T (iNKT) cells in pathophysiology of dyspeptic disorders, number of these two cells in patients with non-ulcer dyspepsia (NUD), peptic ulcer disease (PUD), and gastric cancer (GC) were compared.Patients with dyspepsia were divided into three groups of NUD, PUD, and GC according to their endoscopic and histopathological examinations. Helicobacter pylori infection was diagnosed by rapid urease test and histopathology. The number of peripheral blood CD3+TCRγδ(+) T cells and CD3+Va24Ja18+ iNKT cells were determined by flow cytometry. Immunohistochemistry (IHC) was also used for identifying the TCRγδ+ cells.Forty two patients with NUD (31.6%), 44 with PUD (33.1%), and 47 with GC (35.3%) were included in the study. The frequency of CD3+TCRγδ(+) T cells in peripheral blood of patients with GC (2.71±0.25) was significantly lower than that in NUD (3.97±0.32, p<0.05) and PUD groups (3.87±0.32, p<0.05). However, there was no significant difference in CD3+TCRγδ(+) T cell percentage between the NUD and PUD groups. The frequency of TCRγδ(+) lymphocytes was significantly lower in tissue samples from patients with GC (4.81±0.53) than in NUD (11.09±1.09, p<0.0001) and PUD groups (11.11±1.01, p<0.0001). Also, we could not find any significant difference in the percentage of mucosal TCRγδ+ cells between the NUD and PUD groups. The results showed no significant difference in iNKT cells percentage among the three groups of patients.The results suggest that decreasing number of γδ T cells may be related to development and progression of gastric cancer.

    Guidelines regarding the impact and value of prophylaxis or maintenance therapy in Equine Gastric Ulcer Syndrome (EGUS) are not well established or defined. The merits and the magnitude of effects of prophylaxis for spontaneous or recurrent squamous gastric ulceration in horses in training are uncertain. To pool data from randomised controlled trials (RCTs) to eliminate reporting bias and evaluate the efficacy of prophylactic omeprazole in the prevention of EGUS in training horses, and secondarily to compare prophylactic dosages of omeprazole. Meta-analysis. This meta-analysis was conducted according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic literature search identified RCTs comparing omeprazole prophylaxis with sham in prevention of EGUS. Data were analysed using the Mantel-Haenszel test method to calculate risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CIs). Primary outcome was efficacy of prophylaxis. Secondary outcome was endoscopic severity of ulceration. The influence of study characteristics on the outcomes was examined by subgroup analyses. In preventing gastric ulcer occurrence, omeprazole prophylaxis was superior to sham in training horses (7 trials, 566 horses, RR 0.28, 95% CI 0.18 to 0.43; 23.4% in omeprazole prophylaxis versus 77.2% in sham; high quality evidence). Prevalence of ulceration was 75.3% and 87.2% in the sham arms of the 1 mg/kg and 2 mg/kg omeprazole groups, respectively. Severity scores were significantly lower for omeprazole versus sham (mean difference [MD] -1.05; 95% CI -1.35 to -0.69). Subgroup analyses comparing prophylactic omeprazole dosages resulted in a mean difference of -0.94 and -1.60 for the 1 mg/kg and 2 mg/kg groups, respectively. Studies showed heterogeneity with regard to prophylactic dose. Omeprazole prophylaxis in active training horses significantly reduces gastric ulceration compared with no prophylaxis

    In order to elucidate the contribution of cycloxygenase (COX) enzymes in the anti-oxidant and anti-inflammatory mechanisms of nesfatin-1, which improves the healing process of chronic gastric ulcers, either acetic acid (80%; ulcer groups; n = 40) or saline (control groups; n = 40) was applied to the serosal surface of male Sprague Dawley rats' stomachs for 1 min. Both the control and ulcer groups were treated daily with either i.p. saline or nesfatin-1 (0.3 μg/kg; for 3 days). Nesfatin-1-treatment was preceded with i.p. saline, COX-2 inhibitor NS-398 (2 mg/kg), COX-1 inhibitor ketorolac (3 mg/kg) or non-selective COX inhibitor indomethacin (5 mg/kg) for 3 days. The rats were decapitated at the end of the third day, and their trunk blood was collected for the measurements of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-10 using ELISA. The induction of ulcers resulted in increased macroscopic scores, along with elevated gastric malondialdehyde, luminol- and lucigenin-enhanced chemiluminescence levels and myeloperoxidase activity. On the other hand, nesfatin-1 treatment abolished these elevations. Depleted glutathione, superoxide dismutase and catalase activity levels in the saline-treated ulcer group were preserved in the nesfatin-1-treated ulcer group. Increased levels of serum TNF-α, IL-1β, IL-10 in the saline-treated ulcer group, as compared to control group, were significantly decreased in the nesfatin-1-treated ulcer group. The inhibition of COX-1, and/or COX-2 reversed most of the alterations induced with nesfatin-1, but COX-2-blockade was consistently more effective to abolish all nesfatin-1-induced changes. Our results suggest that nesfatin-1 ameliorates ulcer-induced inflammatory response through the modulation of oxidant-antioxidant balance. As selective pharmacological inhibition of COX-1 or COX-2 suppresses the antioxidant/anti-inflammatory effects of nesfatin-1, it appears that nesfatin-1 decreases inflammatory mediators and

    Although the overall prevalence of peptic ulcer disease (PUD) has decreased in modern times, its actual incidence may be underestimated owing to the nonspecific clinical presentations patients' manifest. The potential lethal complications that can result from PUD include life-threatening abdominal hemorrhage and bowel perforation that result in significant morbidity and mortality. Computed tomography (CT) imaging historically lacks specificity in detecting PUD-related pathology in the stomach and proximal small bowel segments. Therefore, these are potential pitfalls in the radiologist's search pattern on abdominopelvic CT imaging. This article highlights imaging features of uncomplicated PUD on CT imaging in order to allow for early detection of this disease process on imaging and the prevention of potential high-grade complications by recommending esophagogastroduodenoscopy.

    We evaluate the curative efficacy of the ethanolic extract (EET) of roots from Arctium lappa (bardana) in healing of chronic gastric ulcers induced by 80% acetic acid in rats and additionally studies the possible mechanisms underlying this action. Oral administration of EET (1, 3, 10 and 30mg/kg) reduced the gastric lesion area in 29.2%, 41.4%, 59.3% and 38.5%, respectively, and at 10mg/kg promoted significant regeneration of the gastric mucosa, which was confirmed by proliferating cell nuclear antigen immunohistochemistry. EET (10mg/kg) treatment did not increase the gastric mucus content but restored the superoxide dismutase activity, prevented the reduction of glutathione levels, reduced lipid hydroperoxides levels, inhibited the myeloperoxidase activity and reduced the microvascular permeability. In addition, EET reduced the free radical generation and increased scavenging of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals in vitro. Furthermore, intraduodenal EET (10 and 30mg/kg) decreased volume and acidity of gastric secretion. Total phenolic compounds were high in EET (Folin-Ciocalteau assay) and the analysis by liquid chromatography-mass spectrometry revealed that the main compounds present in EET were a serie of hydroxycinnamoylquinic acid isomers. In conclusion, these data reveal that EET promotes regeneration of damaged gastric mucosa, probably through its antisecretory and antioxidative mechanisms. Copyright © 2012 Elsevier Ltd.

    Non-Helicobacter pylori, non-NSAID peptic ulcer disease (PUD), termed idiopathic PUD, is increasing in Korea. Diagnosis is based on exclusion of common causes such as H. pylori infection, infection with other pathogens, surreptitious ulcerogenic drugs, malignancy, and uncommon systemic diseases with upper gastrointestinal manifestations. The clinical course of idiopathic PUD is delayed ulcer healing, higher recurrence, higher re-bleeding after initial ulcer healing, and higher mortality than the other types of PUD. Genetic predisposition, older age, chronic mesenteric ischemia, cigarette smoking, concomitant systemic diseases, and psychological stress are considered risk factors for idiopathic PUD. Diagnosis of idiopathic PUD should systematically explore all possible causes. Management of this disease is to treat underlying disease followed by regular endoscopic surveillance to confirm ulcer healing. Continuous proton pump inhibitor therapy is an option for patients who respond poorly to the standard ulcer regimen.

    After the completion and evaluation of 17 patients studies using technetium-99m-labeled sucralfate for the detection of ulcerated areas, the authors felt that the technical aspects of the studies should be evaluated. The factors for evaluation are: the time the patient is kept fasting; the time the patient is being imaged and rotated for various anatomic views; the technologist time and camera time that are involved in one study; and the cost factor of the testing procedure. Based on the findings of their small sample of patients, the sensitivity of the test is uncertain.

    Experimental stomach ulcer of the rat was produced by clamping method. Repair processes of the epithelial and glandular cells were examined by LM, SEM, TEM and autoradiograph with 3 H-thymidine at various times after removal of the clamp. The epithelial cells in the vicinity of the defect consisted of the surface cells with a few mucous granuls, parietal cells, endocrine cells and fibrillovesicular cells of Hammond and LaDuer during repair processes. The chief cells appeared after 12 days. After 5 weeks, the defect was completely covered with the epithelium. All kind of the epithelial cells except fibrillovesicular cells can incorporate thymidine precursor during regeneration. (author)

  18. The Influence of Antral Ulcers on Intramural Gastric Nerve Projections Supplying the Pyloric Sphincter in the Pig (Sus scrofa domestica-Neuronal Tracing Studies.

    Directory of Open Access Journals (Sweden)

    Michal Zalecki

    Full Text Available Gastric ulcerations in the region of antrum pylori represent a serious medical problem in humans and animals. Such localization of ulcers can influence the intrinsic descending nerve supply to the pyloric sphincter. The pyloric function is precisely regulated by intrinsic and extrinsic nerves. Impaired neural regulation could result in pyloric sphincter dysfunction and gastric emptying malfunction. The aim of the study was to determine the effect of gastric antral ulcerations on the density and distribution of intramural gastric descending neurons supplying the pyloric sphincter in pigs.The experiment was performed on 2 groups of pigs: healthy gilts (n=6 and gilts with experimentally induced peptic ulcers in the region of antrum pylori (n=6. Gastric neurons supplying pyloric sphincter were labeled using the retrograde neuronal tracing technique (20μl of Fast Blue tracer injected into the pyloric sphincter muscle. After a week survival period the animals were sacrificed and the stomachs were collected. Then, the stomach wall was cross-cut into 0.5cm thick sections taken in specified intervals (section I - 1.5cm; section II - 3.5cm; section III - 5.5cm; section IV - 7.5cm starting from the sphincter. Consecutive microscopic slices prepared from each section were analyzed under fluorescent microscope to count traced neurons. Obtained data were statistically analyzed. The total number of FB-positive perikarya observed within all studied sections significantly decreased from 903.3 ± 130.7 in control to 243.8 ± 67.3 in experimental animals. In healthy pigs 76.1 ± 6.7% of labeled neurons were observed within the section I, 23.53 ± 6.5% in section II and only occasional cells in section III. In experimental animals, as many as 93.8 ± 2.1% of labeled cells were observed within the section I and only 6.2 ± 2.2% in section II, while section III was devoid of such neurons. There were no traced perikarya in section IV observed in both groups of pigs
