    The objective of this study was to explore hair mercury level in association with chronic atrophic gastritis, a precancerous stage of gastric cancer (GC), and thus provide a brand new angle of view on the timely intervention of precancerous stage of GC. We recruited 149 healthy volunteers as controls and 152 patients suffering from chronic gastritis as cases. The controls denied upper gastrointestinal discomforts, and the cases were diagnosed as chronic superficial gastritis (n=68) or chronic atrophic gastritis (n=84). We utilized Mercury Automated Analyzer (NIC MA-3000) to detect hair mercury level of both healthy controls and cases of chronic gastritis. The statistic of measurement data was expressed as mean ± standard deviation, which was analyzed using Levene variance equality test and t test. Pearson correlation analysis was employed to determine associated factors affecting hair mercury levels, and multiple stepwise regression analysis was performed to deduce regression equations. Statistical significance is considered if p value is less than 0.05. The overall hair mercury level was 0.908949 ± 0.8844490 ng/g [mean ± standard deviation (SD)] in gastritis cases and 0.460198 ± 0.2712187 ng/g (mean±SD) in healthy controls; the former level was significantly higher than the latter one (p=0.000healthy controls (phealthy controls (phealthy controls with eating seafood was significantly higher than that in healthy controls without eating seafood (peating seafood was most correlated with hair mercury level and positively correlated in the healthy controls and that the severity of gastritis was most correlated with hair mercury level and positively correlated in the gastritis cases. Multiple stepwise regression analysis indicated that the regression equation of hair mercury level in controls could be expressed as 0.262 multiplied the value of eating seafood plus 0.434, the model that was statistically significant (pfactor affecting the hair mercury level is eating

    Full Text Available Chronic atrophic gastritis (CAG is a very common gastritis and one of the major precursor lesions of gastric cancer, one of the most common cancers worldwide. The molecular mechanism underlying CAG is unclear, but its elucidation is essential for the prevention and early detection of gastric cancer and appropriate intervention. A combination of two-dimensional gel electrophoresis and mass spectrometry was used in the present study to analyze the differentially expressed proteins. Samples from 21 patients (9 females and 12 males; mean age: 61.8 years were used. We identified 18 differentially expressed proteins in CAG compared with matched normal mucosa. Eight proteins were up-regulated and 10 down-regulated in CAG when compared with the same amounts of proteins in individually matched normal gastric mucosa. Two novel proteins, proteasome activator subunit 1 (PSME1, which was down-regulated in CAG, and ribosomal protein S12 (RPS12, which was up-regulated in CAG, were further investigated. Their expression was validated by Western blot and RT-PCR in 15 CAG samples matched with normal mucosa. The expression level of RPS12 was significantly higher in CAG than in matched normal gastric mucosa (P < 0.05. In contrast, the expression level of PSME1 in CAG was significantly lower than in matched normal gastric mucosa (P < 0.05. This study clearly demonstrated that there are some changes in protein expression between CAG and normal mucosa. In these changes, down-regulation of PSME1 and up-regulation of RPS12 could be involved in the development of CAG. Thus, the differentially expressed proteins might play important roles in CAG as functional molecules.

    Full Text Available BACKGROUND: Most studies about aquaporin 3 (AQP3 in the gastrointestinal tract were carried out on both in vivo and in vitro. The role of AQP3-mediated water transport in human gastrointestinal tract is still unclear. Our aim in this study was to explore the expression of AQP3 gene in chronic atrophic gastritis (CAG and chronic superficial gastritis (CSG atients and to determine its possible function in the development of gastritis.
    METHODS: Twenty-two outpatients diagnosed as CSG and 12 outpatients diagnosed as CAG were selected randomly. Ten cases of healthy individuals were selected as normal control group. In all cases, AQP3 gene expression of gastric mucosa was detected by fluorescence quantitative polymerase chain reaction (FQ-PCR.
    RESULTS: The AQP3 gene expression was significantly higher in gastric mucosa of CSG and healthy individuals than that in CAG (P<0.01. However, there was no significant difference in the AQP3 gene expression between helicobacter pylori positive patients and helicobacter pylori negative patients (P>0.05.
    CONCLUSIONS: AQP3 expression might play certain role in the occurrence and development of gastritis.

    AIM: To investigate the association of TNF polymorphisms with chronic atrophic gastritis (CAG) and gastric adenocarcinoma in Chinese Han patients.METHODS: The TNFa-e 5 microsatellites and 3 RFLP sites were typed using PCR technique, followed by high-voltage denaturing PAGE with silver staining and restriction enzyme digestion respectively in specimens from 53 patients with CAG and 56 patients with gastric adenocarcinoma and 164 healthy controls. The PCR products were cloned and sequenced.RESULTS: The frequency of TNF-β Ncol*1/2 genotype was higher in patients with chronic atrophic gastritis than in healthy controls, but no significant difference was observed (60.38% vs 46.34%, P=0.076). The frequency of TNa10 allele was significantly higher in patients with chronic atrophic gastritis than in healthy controls (19.81% vs 11.89%,P=0.04). However, it did not relate to age, gender, atrophic degree or intestinal metaplasia in patients with chronic atrophic gastritis. The frequency of TNF-β Ncol*1/2 and d2/d6 genotypes were significantly higher in patients with gastric adenocarcinoma than in healthy individuals(P>0.05).However, TNF-β Ncol*1/2 and d2/d6 genotypes did not relate to age, gender, grade of differentiation and clinicopathologic stage in patients with gastric adenocarcinoma. The frequency of TNFa6b5c1 haplotype homozygote was significantly lower in patients with gastric adenocarcinoma than in healthy controls (1.79% vs15.85%, P=0.006).CONCLUSION: TNFa10 allele may be a risk factor for chronic atrophic gastritis. TNF-β Ncol*1/2 and d2/d6 genotypes are associated with the susceptibility to gastric adenocarcinoma,whereas TNFa6b5c1 haplotype homozygote may contribute to the resistance against gastric adenocarcinoma.

    Full Text Available Abstract Background Recent studies have reported associations of DNA repair pathway gene variants and risk of various cancers and precancerous lesions, such as chronic atrophic gastritis (CAG. Methods A nested case-control study within the German population-based ESTHER cohort was conducted, including 533 CAG cases and 1054 controls. Polymorphisms in eleven DNA repair genes (APEX1, ERCC1, ERCC2/XPD, PARP1 and XRCC1, in CD3EAP/ASE-1 and PPP1R13L were analysed. Results No association was disclosed for any of the analysed polymorphisms. Nor did stratified analyses according to ages Conclusions The results of this large German case-control study do not reveal associations of DNA repair pathway polymorphisms and risk of CAG. On the basis of a large number of CAG cases, they do not support associations of DNA repair pathway SNPs with CAG risk, but suggest the need of larger studies to disclose or exclude potential weak associations, or of studies with full coverage of candidate genes.

    Full Text Available Previous in vitro and animal experiments have shown that sulforaphane, which is abundant in broccoli, inhibits Helicobacter pylori (H. pylori infection and blocks gastric tumor formation. This suggests that broccoli consumption prevents chronic atrophic gastritis (CAG introduced by H. pylori infection and, therefore, gastric cancer. For an epidemiological investigation of the relationship between the broccoli consumption and CAG, a cross-sectional study of 438 male employees, aged 39 to 60 years, of a Japanese steel company was conducted. CAG was serologically determined with serum cut-off values set at pepsinogen I < or = 70 ng/ml and a ratio of serum pepsinogen I/pepsinogen II < or = 3.0. Broccoli consumption (weekly frequency and diet were monitored by using a 31-item food frequency questionnaire. The prevalence of CAG among men who ate broccoli once or more weekly was twice as high as that among men who consumed a negligible amount (P < 0.05. Multiple logistic regression analysis indicated that broccoli consumption once or more weekly significantly increased the risk for CAG (odds ratio, 3.06; 95% confidence interval, 1.12-8.38; P < 0.05, after controlling for age, education, cigarette smoking, and alcohol consumption. The present study failed to show an expected association between frequent broccoli consumption and a low prevalence of CAG.

    AIM: To demonstrate the effect of Hewei-Decoction(Decoction for regulating the stomach) on chronic atrophic gastritis (CAG) and eradication of Helicobacter pylori.METHODS: Ninety patients with CAG entering the investigation were divided into six differentiation syndromes, based on their major symptoms and signs.Hewei-Decoction was taken by all the patients orally for 4or 8 wk. The efficacy was assessed by both the composite accumulation of reduced scores of major symptoms and the eradication of H pylori.χ2 test was used to compare the efficacy between Hpylori-positive and negative cases,and to disclose the relationship between efficacy and eradication of H pylori.REStULTS: In patients with six different syndrome types,the efficacy of Hewei-Decoction was 91.67% (11/12),92.86% (13/14), 97.22% (35/36), 87.50% (14/16),75.00% (6/8), 75.00% (3/4) respectively. The rate of highly efficacious was 58.33% (7/12), 50.00% (7/14),77.78% (28/36), 62.50% (10/16), 12.50% (1/8) and25.00% (1/4), respectively. The total efficacy was 91.11%(82/90), and the rate of highly efficacious was 60.00%(54/90). The eradication rate of H pyloriwas 67.86%(38/56). The therapeutic effect of Hewei-Decoction was better in H pylori positive cases than that in Hpylori-negative cases with the total effect of 96.43% vs82.35% (P<0.05).In 56 H pylori positive cases, the therapeutic effect was better in H pylori eradicated cases than that in H pyloriexistent cases with the total effect of 97.37% vs 72.22%(P<0.01).CONCLUSION: Hewei-Decoction is effective in most cases of all the syndrome types. The results indicate that eradication of H pylori is one of the important mechanisms for alleviation of symptoms and signs. Also, the decoction is efficacious in H pylori-negative cases.

    AIM: To investigate a pathophysiological role of cathepsin W (CatW), a putative thiol-dependent cysteine protease,which is specifically expressed in cytotoxic lymphocytes,in different types of chronic inflammation of the gastric mucosa.METHODS: Gastric and duodenal biopsies of patients with Helicobacter pylori ( H pylori)-associated active gastritis ( Hp,n = 19), chemically induced reactive gastritis (CG, n = 17),autoimmune atrophic gastritis (AIG, n = 20), lymphocytic corpus gastritis (LG, n = 29), celiac disease (CD, n = 10),and corresponding controls (n = 24) were analyzed by immunohistochemistry for the expression of CatW and CD45. Furthermore, immunohistochemical double staining with anti-CD3 and anti-cathepsin was performed for the samples of AIG.RESULTS: Median values of CatW-expressing cells among CD45-positive immune cells were between 2% and 6% for normal gastric mucosa, CG, and LG, whereas the corresponding value was significantly increased for AIG (24.7%, P<0.001) and significantly decreased for HP (0.7%, P<0.05). Double staining with anti-CD3 and antiCatW antibodies revealed that >90% of CatW-expressing cells in gastric mucosa of AIG were T cells. Duodenal mucosa had significantly more CatW/CD45-positive cells than normal gastric mucosa (median: 17.8% vs 2%, P<0.01).The corresponding proportion of CatW/CD45-positive cells was decreased in CD compared to duodenal mucosa (median: 2.1% vs 17.8%, P<0.05).CONCLUSION: The opposite findings regarding the presence of CatW-positive cells in AIG (increase) and CD (decrease) reflects the different cellular composition of immune cells involved in the pathogenesis of these diseases.

    The expression of interleukin-11 (IL-11) and its products STAT3 and phospho-STAT3 (p-STAT3) in patients with chronic superficial gastritis (CSG), chronic atrophic gastritis (CAG), and gastric cancer (GC) may provide insight into the diagnostic role of the IL-11/STAT3 signaling pathway in GC. Gastric mucosa specimens and serum samples were collected from 90 patients with CSG, CAG, and GC (30/group). The expression of IL-11, STAT3, and p-STAT3 was detected via immunohistochemistry and western blot. Additionally, serum levels of IL-11 were measured by enzyme-linked immunosorbent assay. For IL-11, 60% stained positive in CAG and 83.3% stained positive in GC, which were both higher than the value observed for CSG (33.3%). Moreover, the percent positive for IL-11 in GC was higher than that in CAG (P < 0.05). The percent positive for STAT3 in CAG (80%) and GC (83.3%) was higher than that in CSG (53.3%) (P < 0.05). Compared with CSG (36.7%), the percent positive for p-STAT3 in CAG (63.3%) and GC (86.7%) was also significantly higher. STAT3 expression was similar in GC and CAG, which was significantly higher than that in CSG. Expectedly, p-STAT3 expression gradually increased from CSG to CAG to GC. Furthermore, p-STAT3 levels were higher in GC tissues than in CAG (P < 0.01). Intriguingly, serum IL-11 levels gradually increased from CSG to CAG to GC, which coincided with disease severity. Together, these results suggest that the IL-11/STAT3 signaling pathway plays a critical role in human CAG, and may provide new targets to prevent and treat GC. PMID:27173233

    Vitamin B12 deficiency is common in developing countries and should be suspected in patients with unexplained anaemia or neurological symptoms. Dermatological manifestations associated with this deficiency include skin hyper- or hypopigmentation, angular stomatitis and hair changes. We report a case of a 28-year-old man who presented to the Sultan Qaboos University Hospital in Muscat, Oman, in November 2013 with localised hyperpigmentation of the palmar and dorsal aspects of both hands of two months' duration. Other symptoms included numbness of the hands, anorexia, weight loss, dizziness, fatigability and a sore mouth and tongue. There was no evidence of hypocortisolaemia and a literature search revealed a possible B12 deficiency. The patient had low serum B12 levels and megaloblastic anaemia. An intrinsic factor antibody test was negative. A gastric biopsy revealed chronic gastritis. After B12 supplementation, the patient's symptoms resolved. Family physicians should familiarise themselves with atypical presentations of B12 deficiency. Many symptoms of this deficiency are reversible if detected and treated early. PMID:26357561

    To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities

    The aim of this study is to discuss whether the methylation levels of Runx3 could be used as the early biomarker for predicting the prognosis in chronic atrophic gastritis (CAG) patients. A total of 200 subjects including 60 controls without CAG (Group 1), 70 patients with mild CAG (Group 2), and 70 patients with moderate and severe CAG (Group 3) were recruited for this cross-sectional investigation in the Department of Gastroenterology in Daqing Oilfield General Hospital from July 2013 to May 2014. The MlALDI-TOF-MS was used to measure the methylation levels of Runx3 in all of the subjects. Real-time quantitative reverse transcription polymerase chain reaction and western blotting were chosen to determine the expression levels of Runx3. The correlations between methylation levels of Runx3 among these CAG patients and their prognosis were shown by logistic regression models. The results demonstrated that the methylation levels of CpG13, CpG14, and CpG15 in Runx3 were higher in Group 3 than those in Groups 1 and 2 (P <0.05), whereas the mRNA and protein expression levels of Runx3 were lower in Group 3 than those in Groups 1 and 2 (P <0.05). There were significantly negative correlations between the methylation levels of Runx3 with its expression and the healing prognosis of CAG patients. In brief, this study proved that the hypermethylation modifications of CpG13, CpG14, and CpG15 in the promoter region of Runx3 could result in the down regulation of Runx3 expression to affect the prognosis of CAG. So the methylation levels of these CpG sites in Runx3 in the peripheral blood can be used as the biomarker for predicting the healing prognosis of CAG patients. PMID:27196446

    Full Text Available Objective. Gastric acid plays an important part in the prevention of bacterial colonization of the gastrointestinal tract. If these bacteria have an ability of hydrogen (H2 fermentation, intraluminal H2 gas might be detected. We attempted to measure the intraluminal H2 concentrations to determine the bacterial overgrowth in the gastrointestinal tract. Patients and methods. Studies were performed in 647 consecutive patients undergoing upper endoscopy. At the time of endoscopic examination, we intubated the stomach and the descending part of the duodenum without inflation by air, and 20 mL of intraluminal gas samples of both sites was collected through the biopsy channel. Intraluminal H2 concentrations were measured by gas chromatography. Results. Intragastric and intraduodenal H2 gas was detected in 566 (87.5% and 524 (81.0% patients, respectively. The mean values of intragastric and intraduodenal H2 gas were 8.5±15.9 and 13.2±58.0 ppm, respectively. The intraduodenal H2 level was increased with the progression of atrophic gastritis, whereas the intragastric H2 level was the highest in patients without atrophic gastritis. Conclusions. The intraduodenal hydrogen levels were increased with the progression of atrophic gastritis. It is likely that the influence of hypochlorhydria on bacterial overgrowth in the proximal small intestine is more pronounced, compared to that in the stomach.

    2011-01-01

    Atrophic gastritis, is the main consequence of long-standing Helicobacter pylori infection, and is linked to the development of gastric cancer. The severity of atrophic gastritis is related to the lifetime risk of gastric cancer development, especially in terms of its degree and extent of mucosal damage. Therefore, it is important for clinicians to assess the severity of atrophic gastritis, interfere with the disease progress, and reverse gastric mucosal atrophy. In the article, we demonstrated some methods (conventional endoscopy, modern endoscopic technology and noninvasive methods) that may help assess the severity of atrophic gastritis and select the reasonable treatment protocols.

    AIM: To determine the association between H pylori infection and serum ghrelin levels in patients without atrophic gastritis.METHODS: Fifty consecutive patients (24 males and 26 females) with either H pylori-positive gastritis (n = 34) or H pylori-negative gastritis (n = 16) with normal gastric acid secretion determined by 24-h pHmetry and without atrophic gastritis in histopathology were enrolled in this study. Thirty-four H pylori-infected patients were treated with triple therapy consisting of a daily regimen of 30 mg lansoprazole bid, 1 g amoxicillin bid and 500 mg clarithromycin bid for 14 d, followed by an additional 4 wk of 30 mg lansoprazol treatment. H pylori infection was eradicated in 23 of 34 (67.6%) patients. H pylori-positive patients were given eradication therapy. Gastric acidity was determined via intragastric pH catethers. Serum ghrelin was measured by radioimmunoassay (RIA).RESULTS: There was no significant difference in plasma ghrelin levels between H pylori -positive and H pylori-negative groups (81.10 ± 162.66 ng/L vs 76.51 ± 122.94 ng/L). In addition, there was no significant difference in plasma ghrelin levels and gastric acidity levels measured before and 3 mo after the eradication therapy.CONCLUSION: H pylori infection does not influence ghrelin secretion in patients with chronic gastritis without atrophic gastritis.

    Full Text Available Background/Aim. Hepcidin, an iron regulatory hormone, is increased in response to inflammation and some infections. We investigated the relationships among serum prohepcidin, iron status, Helicobacter pylori infection status, and the presence of gastric mucosal atrophy. Methods. Seventy subjects undergoing esophagogastroduodenoscopy underwent multiple gastric biopsies, and the possibility of H. pylori infection and the degree of endoscopic and histologic gastritis were investigated. In all subjects, serum prohepcidin and iron parameters were evaluated. Results. No correlations were observed between serum prohepcidin levels and the other markers of anemia, such as hemoglobin, serum iron, ferritin, and total iron binding capacity. Serum prohepcidin levels were not significantly different between the H. pylori-positive group and the H. pylori-negative group. Serum prohepcidin levels in atrophic gastritis patients were significantly lower than those in subjects without atrophic gastritis irrespective of H. pylori infection. Conclusion. Serum prohepcidin levels were not altered by H. pylori infection. Serum prohepcidin levels decrease in patients with atrophic gastritis, irrespective of H. pylori infection. It suggests that hepcidin may decrease due to gastric atrophy, a condition that causes a loss of hepcidin-producing parietal cells. Further investigations with a larger number of patients are necessary to substantiate this point.

    Abstract A meta-analysis was performed to assess the diagnostic value of gastrin-17 (G-17) for the early detection of chronic atrophic gastritis (CAG). An extensive literature search was performed, with the aim of selecting publications that reported the accuracy of G-17 in predicting CAG, in the following databases: PubMed, Science Direct, Web of Science, Chinese Biological Medicine, Chinese National Knowledge Infrastructure, Wanfang, and VIP. To assess the diagnostic value of G-17, the following statistics were estimated and described: sensitivity, specificity, diagnostic odds ratios (DOR), summary receiver operating characteristic curves, area under the curve (AUC), and 95% confidence intervals (CIs). Thirteen studies that met the inclusion criteria were included in this meta-analysis, comprising 894 patients and 1950 controls. The pooled sensitivity and specificity of these studies were 0.48 (95% CI: 0.45–0.51) and 0.79 (95% CI: 0.77–0.81), respectively. The DOR was 5.93 (95% CI: 2.93–11.99), and the AUC was 0.82. G-17 may have potential diagnostic value because it has good specificity and a moderate DOR and AUC for CAG. However, more studies are needed to improve the sensitivity of this diagnostic tool in the future. PMID:27149493

  5. Netazepide, a gastrin receptor antagonist, normalises tumour biomarkers and causes regression of type 1 gastric neuroendocrine tumours in a nonrandomised trial of patients with chronic atrophic gastritis.

    Directory of Open Access Journals (Sweden)

    Andrew R Moore

    Full Text Available INTRODUCTION: Autoimmune chronic atrophic gastritis (CAG causes hypochlorhydria and hypergastrinaemia, which can lead to enterochromaffin-like (ECL cell hyperplasia and gastric neuroendocrine tumours (type 1 gastric NETs. Most behave indolently, but some larger tumours metastasise. Antrectomy, which removes the source of the hypergastrinaemia, usually causes tumour regression. Non-clinical and healthy-subject studies have shown that netazepide (YF476 is a potent, highly selective and orally-active gastrin/CCK-2 receptor antagonist. Also, it is effective in animal models of ECL-cell tumours induced by hypergastrinaemia. AIM: To assess the effect of netazepide on tumour biomarkers, number and size in patients with type I gastric NETs. METHODS: We studied 8 patients with multiple tumours and raised circulating gastrin and chromogranin A (CgA concentrations in an open trial of oral netazepide for 12 weeks, with follow-up 12 weeks later. At 0, 6, 12 and 24 weeks, we carried out gastroscopy, counted and measured tumours, and took biopsies to assess abundances of several ECL-cell constituents. At 0, 3, 6, 9, 12 and 24 weeks, we measured circulating gastrin and CgA and assessed safety and tolerability. RESULTS: Netazepide was safe and well tolerated. Abundances of CgA (p<0.05, histidine decarboxylase (p<0.05 and matrix metalloproteinase-7(p<0.10 were reduced at 6 and 12 weeks, but were raised again at follow-up. Likewise, plasma CgA was reduced at 3 weeks (p<0.01, remained so until 12 weeks, but was raised again at follow-up. Tumours were fewer and the size of the largest one was smaller (p<0.05 at 12 weeks, and remained so at follow-up. Serum gastrin was unaffected. CONCLUSION: The reduction in abundances, plasma CgA, and tumour number and size by netazepide show that type 1 NETs are gastrin-dependent tumours. Failure of netazepide to increase serum gastrin further is consistent with achlorhydria. Netazepide is a potential new treatment for type 1 NETs

    Full Text Available BACKGROUND: Helicobacter pylori is the most common human pathogen which causes chronic gastritis, leading to serious complications. The aim was to study the incidence of H. pylori infection and the risk factors associated with chronic atrophic gastritis using simple diagnostic procedures. MATERIALS AND METHODS: Biopsy samples were collected from 146 chronic atrophic gastritis patients. Rapid Urease Test (RUT and dark field microscopy were used to diagnose the presence of H. pylori infection. The prevalence rate of H. pylori infection in relation to age, sex, smoking and alcohol consumption was studied. RESULTS: 88 (60.27% cases were positive for RUT and also for the characteristic cork screw motility under dark field microscopy. Prevalence rate was high in younger age group and among female. We found no correlation of H. pylori infection with smoking and alcohol consumption. CONCLUSION: It has been found that H. pylori is a major causative agent for atrophic gastritis and RUT is a simple cost efficient diagnostic test for H. pylori. The association of H. pylori infection with age, sex, smoking and alcohol consumption is variable and requires further studies to establish any relationship.

    Autoimmune metaplastic atrophic gastritis (AMAG) is a significant risk factor for pernicious anemia and gastric neoplasia. Still, the histologic features of AMAG are frequently overlooked, especially in the early stages of the disease. The purpose of our study, therefore, was to catalogue the progression of histologic changes that precede the development of AMAG in affected individuals. Over a 2-year period (2012 to 2014), the diagnosis of AMAG was rendered on material from 113 patients seen at Johns Hopkins Hospital (∼1.8% of "in house" gastric biopsies). Prior gastric body biopsies had been performed on 54 (48%) patients in the cohort, and the majority of these specimens had also shown AMAG. Eighteen of the previous biopsies, however, carried a diagnosis other than AMAG: 13 inactive chronic gastritis, 2 acute Helicobacter pylori gastritis, and 1 each of eosinophilic gastritis, iron pill gastritis, and proton-pump inhibitor-like effect. Upon review of these 18 biopsies, the most common histologic findings were heavy full-thickness or deep lamina propria chronic inflammation (12), inflammatory destruction of oxyntic glands (12), metaplasia (intestinal, pyloric, or pancreatic acinar) (10), prominent lamina propria eosinophils (8), and parietal cell pseudohypertrophy (4). At least 2 of these features were present in the majority (13, 72%) of the biopsies. In addition, 7 (58%) of these patients were also found to have another autoimmune or inflammatory disorder before the diagnosis of AMAG. Although subtle, histologic features of developing AMAG are identifiable in routine gastric body biopsies. When metaplasia, full-thickness chronic inflammation, and/or oxyntic destruction are seen, a note suggesting laboratory testing and/or close clinical follow-up in this subset of patients may be warranted.

    The mucosa of the esophagus, the stomach, the small intestine, the large intestine and rectum are unremittingly challenged by adverse micro-environmental factors, such as ingested pathogenic and non-pathogenic bacteria, and harsh secretions with digestive properties with disparate pH, as well as bacteria and secretions from upstream GI organs. Despite the apparently inauspicious mixture of secretions and bacteria, the normal GI mucosa retains a healthy state of cell renewal. To by-pass the tough microenvironment, the epithelia of the GI react by speeding-up cell exfoliation, by increasing peristalsis, eliminating bacteria through secretion of plasma cell-immunoglobulins and by increasing production of natural antibacterial enzymes (lysozyme) and host defense peptides (defensin-5). Lysozyme was recently found up-regulated in Barrett's esophagitis, in chronic gastritis, in gluten-induced atrophic duodenitis (celiac disease), in collagenous colitis, in lymphocytic colitis and in Crohn's colitis. This up-regulation is a response directed towards the special types of bacteria thriving in the microenvironment in each of the aforementioned clinical inflammatory maladies. The purpose of that up-regulation is to protect the mucosa affected by the ongoing chronic inflammation. Bacterial antibiotic resistance continues to exhaust our supply of effective antibiotics. The future challenge is how to solve the increasing menace of bacterial resistance to anti-bacterial drugs. Further research on natural anti-bacterial enzymes such as lysozyme, appears mandatory.

    AIM: To investigate the effect of H pylori eradication on atrophic gastritis and intestinal metaplasia (IM).METHODS: Two hundred and fifty-nine patients with atrophic gastritis in the antrum were included in the study, 154 patients were selected for H pylori eradication therapy and the remaining 105 patients served as untreated group. Gastroscopy and biopsies were performed both at the beginning and at the end of a 3-year follow-up study. Gastritis was graded according to the updated Sydney system.RESULTS: One hundred and seventy-nine patients completed the follow-up, 92 of them received H pylori eradication therapy and the remaining 87 H pyloriinfected patients were in the untreated group. Chronic gastritis, active gastritis and the grade of atrophy significantly decreased in H pylori eradication group (P<0.01). However, the grade of IM increased in H pylori -infected group (P<0.05).CONCLUSION: H pylori eradication may improve gastric mucosal inflammation, atrophy and prevent the progression of IM.

  15. Autoradiographic studies on the cell proliferation of the human chronic gastritis

    International Nuclear Information System (INIS)

    Cell proliferation of human gastric mucosa was studied in the cases of chronic gastritis using the in vitro incubation method of 3H-thymidine autoradiography. The study was carried out using the material consisted of 92 biopsy specimens and 83 stomachs diagnosed as carcinoma, peptic ulcer, duodenal ulcer and chronic gastritis. The labelling index was expressed in a percentage of labelled cells in ratio to the total number of epithelial cells. In the normal gastric mucosae, 3H-TdR labeled cells were in the neck region of the gastric gland, but did not appear in the surface epithelium. Higher incorporation of 3H-TdR was observed in the lower part of the neck region of the glands. The average indices, both labeling and mitotic, were generally higher in the antrum than in the pylorus in the cases of chronic gastritis and also higher than normal mucosae. Superficial gastritis showed many labeled cells which were located in the neck region and foveolae. Simple gastitis showed scattered labeled cells in various parts of mucosae. In atrophic and atrophic hyperplastic gastritis, labeled cells were found in the neck and fobeolae of the gastric glands. Metaplastic gastritis showed labeled cells especially in the neck regions. The average labeling index is higher in simple chronic gastritis than in other superficial gastritis, atrophic, atrophic hyperplastic and metaplastic gastritis. Information concerned with cell renewal and proliferation is important for further understanding of the development of disease. (J.P.N.)

    Acupuncture has been used to treat chronic atrophic gastritis (CAG) in traditional Chinese medicine (TCM) for centuries. In this study, we evaluated the effect of acupuncture at Zusanli (ST36), Zhongwan (CV12), and Pishu (BL20) acupoints on weight changes of rats, histological changes of gastric glands, and expressions changes of nuclear factor-kappa B (NF-κB) p65, microRNA- (miR-) 155, miR-21, and miR-146a in CAG rats induced by N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) combined with irregular diet. Consequently, we found that acupuncture treatment elevated body weight of rats significantly when compared to the model group. By observing histological changes, we found that the acupuncture group showed better improvement of gastric mucosa injury than the model group. Our results also demonstrated upregulation of NF-κB p65, miR-155, and miR-21 in gastric tissue of CAG rats and a positive correlation between miR-155 and miR-21. Relatively, expression of miR-146a was downregulated and negative correlation relationships between miR-146a and miR-155/miR-21 in CAG rats were observed. Additionally, expressions of NF-κB p65, miR-155, and miR-21 were downregulated and miR-146a was upregulated after acupuncture treatment. Taken together, our data imply that acupuncture can downregulate NF-κB p65, miR-155, and miR-21 and upregulate miR-146a expression in CAG rats. NF-κB p65, miR-155, miR-21, and miR-146a may play important roles in therapeutic effect of acupuncture in treating CAG. PMID:27293468

    Human gastric diseases have shown significant changes in the activity and expression of superoxide dismutase (SOD) isoforms. The aim of this study was to detect Mn-SOD activity and expression in the tissue of gastric mucosa, primarily in chronic gastritis (immunohistochemical Helicobacter pylori-negative gastritis, without other pathohistological changes) and to evaluate their possible connection with pathohistological diagnosis. We examined 51 consecutive outpatients undergoing endoscopy for upper gastrointestinal symptoms. Patients were classified based on their histopathological examinations and divided into three groups: 51 patients (archive samples between 2004-2009) with chronic immunohistochemical Helicobacter pylori-negative gastritis (mononuclear cells infiltration were graded as absent, moderate, severe) divided into three groups. Severity of gastritis was graded according to the updated Sydney system. Gastric tissue samples were used to determine the expression of Mn-SOD with anti-Mn-SOD Ab immunohistochemically. The Mn-SOD expression was more frequently present in specimens with severe and moderate inflammation of gastric mucosa than in those with normal mucosa. In patients with normal histological finding, positive immunoreactivity of Mn-SOD was not found. Our results determine the changes in Mn-SOD expression occurring in the normal gastric mucosa that had undergone changes in the intensity of chronic inflammatory infiltrates in the lamina propria.

    Aim: To investigate the effect of geranylgeranylacetone (GGA) on the progres-sion of atrophic gastritis in rats and its potential mechanism. Methods: Atrophic gastritis was induced in Sprague-Dawley rats with 0.1% ammonia solution, 60% ethanol, and 20 mmol/L deoxycholic acid for 24 weeks. Accompanied by the induction of atrophic gastritis, 200 mg/kg GGA was administered by oral gavage for 8 weeks (weeks 17-24). The histological changes in gastric mucosa were quantitated by the index of inflammation, the gastric mucosal thickness, and the amount of glands of 1 mm horizontal length in antrum. Endogenous heat shock protein (HSP)70 levels and distribution were determined by immunoblotting and immunohistochemistry in gastric mucosa. Results: GGA alleviated the pathologi-cal progression of atrophic gastritis with inflammation relief (inflammation index: 1.40 in the GGA group and 1.65 in the atrophic gastritis group) and glandular restoration (rnucosal thickness and quantity of glands: 194.3 μm and 38.7 mm in the GGA group; 123.3 μm and 32.7 mm in the atrophic gastritis group; P<0.05). GGA significantly induced HSP70 synthesis (P<0.05). Moreover, quercetin, an inhibitor of HSP70 expression, aggravated the infiltration of inflammatory cells and glandular loss in the antrum. Conclusion: GGA prevented the progression of atrophic gastritis in rats via the induction of HSP70 expression.

    The relationship between serum PG I, PG II levels and extent of atrophic gastritis was examined. The subjects were 64 patients (male: 32, female: 32, 51.9 years old on average) with established diagnosis of either atrophic gastritis or normal. In the X-ray gastric examination, Fuji Computed Radiography (FCR) was used to obtain clear-cut images of the gastric area. Concerning the serum PG I level, patients in the group with atrophic gastritis showed lower levels than those of the people in the group with no atrophic change, but the variation was wide, and no definite tendency was seen in the relationship between the atrophic change and the serum PG I levels. Concerning the serum PG II level, as the atrophic change progresses, the serum PG II level tended to increase gradually. A significant reduction in the PG I/II ratio was seen in the group with atrophic changes (p<0.01) in comparison with the group with no atrophic changes, and the PG I/II value tended to decrease. In conclusion, as a relationship between the atrophic change and the serum PG levels had a wide variation, we considered it to be difficult to understand the presence and extent of the atrophic gastritis by measuring serum PG levels.

    AIM: To investigate the possible relationships between gastric autoimmune phenomena and clinical presentations of this disorder, in consecutive atrophic body gastritis patients.METHODS: A total of 140 atrophic body gastritis patients,diagnosed as consecutive outpatients presenting with macrocytic or iron deficiency anemia, or longstanding dyspepsia underwent gastroscopy with antral and body biopsies, assay of intrinsic factor, parietal cells and Helicobacter pylori(H pylori) antibodies. Gastritis was assessed according to Sydney System.RESULTS: Parietal cell antibodies were equally distributed in all clinical presentations, whereas the positivity of intrinsic factor antibodies (49/140, 35%) was significantly higher in pernicious anemia patients (49.2%) than in iron deficiency (21.1%) and dyspeptic patients (27.8%). No specific pattern of autoantibodies was related to the clinical presentations of atrophic body gastritis. A positive correlation was obtained between the body atrophy score and the intrinsic factor antibody levels (r = 0.2216,P = 0.0085). Associated autoimmune diseases were present in 25/140 (17.9%) patients, but the prevalence of autoimmune diseases was comparable, irrespective of the clinical presentations.CONCLUSION: The so-called hallmarks of gastric autoimmunity, particularly in intrinsic factor antibody cannot be usefully employed in defining an autoimmune pattern in the clinical presentations of ABG.

    Full Text Available Introduction. We hereby describe the case of a young female patient who presented with pseudothrombotic microangiopathy, as well as pancytopenia accompanied by autoimmune atrophic gastritis. Case Presentation. A 36-year-old Caucasian woman presented to the emergency department with fatigue and dyspnea on minimal exertion. Physical examination was unremarkable except for pallor and noninjected conjunctiva. Laboratory tests revealed high LDH and low hemoglobin, white blood cells, platelets, and haptoglobin. The peripheral blood smear showed schistocytes suggestive of pseudothrombotic microangiopathy. Low cobalamin level and hyperhomocysteinemia were also detected. Autoimmune atrophic gastritis was confirmed by gastric biopsy and positive anti-intrinsic factor antibodies. Vitamin B12 supplements were given which led to rapid recovery and normalization of blood parameters. Conclusion. This case highlights the importance and serves as a reminder to clinicians to rule out cobalamin deficiency and autoimmune atrophic gastritis in patients presenting with a picture suggestive of thrombotic thrombocytopenic purpura and pancytopenia, which was completely reversible after appropriate replacement therapy without recurring to unnecessary and invasive procedures such as plasma exchange.

    A meta-analysis was performed to assess the diagnostic value of gastrin-17 (G-17) for the early detection of chronic atrophic gastritis (CAG).An extensive literature search was performed, with the aim of selecting publications that reported the accuracy of G-17 in predicting CAG, in the following databases: PubMed, Science Direct, Web of Science, Chinese Biological Medicine, Chinese National Knowledge Infrastructure, Wanfang, and VIP. To assess the diagnostic value of G-17, the following statistics were estimated and described: sensitivity, specificity, diagnostic odds ratios (DOR), summary receiver operating characteristic curves, area under the curve (AUC), and 95% confidence intervals (CIs).Thirteen studies that met the inclusion criteria were included in this meta-analysis, comprising 894 patients and 1950 controls. The pooled sensitivity and specificity of these studies were 0.48 (95% CI: 0.45-0.51) and 0.79 (95% CI: 0.77-0.81), respectively. The DOR was 5.93 (95% CI: 2.93-11.99), and the AUC was 0.82.G-17 may have potential diagnostic value because it has good specificity and a moderate DOR and AUC for CAG. However, more studies are needed to improve the sensitivity of this diagnostic tool in the future. PMID:27149493

    AIM: To investigate the therapeutic effects of DA-9601 on sodium taurocholate (TCA)-induced chronic reflux gastritis in SD rats.METHODS: In this study, we have investigated the therapeutic effects of DA-9601 on chronic erosive and atrophic gastritis induced by 6 mo of TCA administration (5 mmol/L in drinking water) in SD rats. RESULTS: Four weeks of DA-9601 administration (0.065%, 0.216% in rat chow), following the withdrawal of TCA treatment, resulted in a significant decrease in total length of erosions in rats in a dose-dependent manner. Furthermore, the indicators of atrophic gastritis, such as reduced mucosal thickness and reduction in the number of parietal cells, were improved by the administration of DA-9601 in a dose-related manner. DA-9601 also attenuated inflammatory cell infiltration and the proliferation of collagenous fiber in the gastric mucosa. The improvement in the reduction of the gastric mucus was observed in the rats receiving a high dose of DA-9601 (0.216%). The therapeutic effect of DA-9601 on experimental chronic erosive gastritis was superior to that of rebamipide (1.08% in rat chow). Biochemical analyses showed increased mucosal prostaglandin E2 and reduced glutathione levels by DA-9601 treatment. CONCLUSION: We suggest that DA-9601 is apromising agent for the treatment of chronic erosive and atrophic gastritis with an etiological factor of bile reflux. Increasedmucosal prostaglandin E2 and reduced glutathione by DA-9601 treatment may be therapeutic mechanisms for chronic erosive and atrophic gastritis.

    In this paper, we attempt to find a valid method to distinguish gastric cancer and atrophic gastritis. Auto-fluorescence and Raman spectroscopy of laser induced (514.5 nm and 488.0 nm) was measured. The serum spectrum is different between normal and cancer. Average value of diagnosis parameter for normal serum, red shift is less than 12 nm and Raman relative intensity of peak C by 514.5 nm excited is stronger than that of 488.0 nm. To gastric cancer, its red shift of average is bigger than 12 nm and relative intensity of Raman peak C by 514.5 nm excited is weaker than that by 488.0 nm. To atrophic gastritis, the distribution state of Raman peaks is similar with normal serum and auto-fluorescence spectrum's shape is similar to that of gastric cancer. Its average Raman peak red shift is bigger than 12 nm and the relative intensity of peak C by 514.5 excited is stronger than that of by 488.0. We considered it as a criterion and got an accuracy of 85.6% for diagnosis of gastric cancer compared with the result of clinical diagnosis.

    Full Text Available Background/Aim. Autoimmune atrophic fundic gastritis induces the pernicious anemia (PA, as well as the changes in both epithelium and endocrine cells of gastric mucosa. The most important complications are: achlorhydria, hypergastrinemia, gastric cancer and enterochromaffin-like ( ECL carcinoid. The aim of this study was to examine ECL carcinoid histogenesis in A-gastritis associated with PA. Methods. During the period from 2000−2006, 65 patients with PA and 30 patients of the control group were examined. Histopathological examination was done in endoscopical biopsies of gastric mucosa fixed in 10% formaldehyde. Paraffin sections were stained with classic hematoxylin-eosin (HE; histochemical AB-PAS (pH 2.5, cytochemical argyrophilic Servier-Munger′s and immunocytochemical PAP methods for G cell identification and chromogranin A antibodies - specific marker for neuroendocrine ECL cells. Both G and ECL cells were counted per 20 fields, of surface 0.0245312 mm2 by a field. Basal gastrin serum levels were also examined by using radioimmunoassay (RIA method. The obtained results were statisticaly calculated by using Student΄s t test. Results. Marked antral G cell hyperplasia associated with corporal ECL hyperplasia was found. ECL cell hyperplasia was of simplex, linear, adenomatoid type to the pattern of intramucous ECL cell carcinoid. An average number of G cells was statistically significant in the patients with PA as compared to the control group (p < 0.05 as well as an average number of ECL cells. Conclusion. We concluded that antral G cell hyperplasia accompanied by gastrinemia induces ECL hyperplasia and ECL corporal carcinoid in A-gastritis and that their histogenesis develops trough simple, linear and adenomatoide hyperplasia. .

    AIM: To investigate the role of artificial neural networks in predicting the presence of thyroid disease in atrophic body gastritis patients.METHODS: A dataset of 29 input variables of 253 atrophic body gastritis patients was applied to artificial neural networks (ANNs) using a data optimisation procedure (standard ANNs, T&T-IS protocol, TWIST protocol). The target variable was the presence of thyroid disease.RESULTS: Standard ANNs obtained a mean accuracy of 64.4% with a sensitivity of 69% and a specificity of 59.8% in recognizing atrophic body gastritis patients with thyroid disease. The optimization procedures (T&T-IS and TWIST protocol) improved the performance of the recognition task yielding a mean accuracy, sensitivity and specificity of 74.7% and 75.8%, 78.8% and 81.8%, and 70.5% and 69.9%, respectively. The increase of sensitivity of the TWIST protocol was statistically significant compared to T&T-IS.CONCLUSION: This study suggests that artificial neural networks may be taken into consideration as a potential clinical decision-support tool for identifying ABG patients at risk for harbouring an unknown thyroid disease and thus requiring diagnostic work-up of their thyroid status.

    AIM: To evaluate fecal calprotectin concentrations (FCCs) in subjects with chronic gastritis and the correlation between FCCs and gastritis activity score. METHODS: FCCs were measured in 61 patients with histological diagnosis of gastritis and in 74 healthy volunteers. Histological grading of gastritis was performed according to the updated Sydney gastritis classification. Patients were subdivided into 2 groups according to the presence/absence of an active gastritis. Patients with chronic active gastritis were divided into 3 subgroups on the basis of the activity score (mild, moderate, marked). FFCs in relation to Helicobacter pylori (H. pylori) infection and proton pump inhibitor (PPI) use were also evaluated. RESULTS: FCCs in patients with chronic active gastritis were not significantly different to FCCs either in subjects with non active gastritis or in healthy controls. Among patients with chronic active gastritis (even marked), FCCs did not significantly differ according to activity score. No significant differences in FCCs were found when considering H. pylori, as well as when considering PPI chronic use. CONCLUSION: FCCs were not significantly increased in subjects with chronic gastritis, even in those patients with a marked neutrophil infiltration. PMID:20632443

To assess the predictive value for chronic autoimmune gastritis (AIG of the combined assay of anti-parietal-cell antibodies (PCA, anti-intrinsic-factor antibodies (IFA, anti-Helicobacter pylori (Hp antibodies, and measurement of blood gastrin. Methods. We studied 181 consecutive patients with anemia, due to iron deficiency resistant to oral replacement therapy or to vitamin B12 deficiency. Results. 83 patients (45.8% tested positive for PCA and underwent gastroscopy with multiple gastric biopsies. On the basis of the histological diagnosis, PCA-positive patients were divided into 4 groups: (1 30 patients with chronic atrophic gastritis; they had high concentrations of PCA and gastrin and no detectable IFA; (2 14 subjects with metaplastic gastric atrophy; they had high PCA, IFA, and gastrin; (3 18 patients with nonspecific lymphocytic inflammation with increased PCA, normal gastrin levels, and absence of IFA; (4 21 patients with multifocal atrophic gastritis with “borderline” PCA, normal gastrin, absence of IFA and presence of anti-Hp in 100% of the cases. Conclusions. The assay of four serological markers proved particularly effective in the diagnostic classification of gastritis and highly correlated with the histological profile. As such, this laboratory diagnostic profile may be considered an authentic “serological biopsy.”

    Introduction: Chronic gastritis is inflammation of the gastric mucosa. It can be non-atrophic and atrophic. Atrophy isdefined as the loss of appropriate glands. It is frequently located in antral mucosa as consequence of Helicobacter pylori infectionand it is associated with intestinal gastric cancer. Goal: Describe histopathological and demographic characteristics of atrophicgastritis. Matherial and methods: We assessed the pathological reports of 100 patients with atrophic gastritis whose characteristicswere evaluated by using a semiquantitative scale of Sidney system of classification of gastritis. To assess the significance betweenthe incidence of various parametres we used ;~2 test. Results: We found that the difference in frequency of atrophic gastritis betweenmen and women was not statistically significant. The difference in distribution is statistically significant in favor of the antrum.Among patients who have atrophy with Helicobacterpylori infection and intestinal metaplasia and those who do not have metaplasia,it was found that the difference is highly statistically significant. Conclusion: The most frequent localisation of atrophic gastritis isantral mucosa. There is no difference between men and women in frequency of atrophic gastritis, while the aging is related with moreoften occurrence of atrophic gastritis.

  7. Effect of experimental immune atrophic gastritis on the induction of gastric carcinoma by x-irradiation in ICR mice

    International Nuclear Information System (INIS)

    Divided doses of 6,000 or 8,000 rad of x-ray were given to the gastric region of ICR/JCL female mice with immune atrophic gastritis produced by the injection with allogenic stomach antigen. The carcinogenic effect of x-rays for inducing gastric carcinoma was significantly increased by this method. Two points can be presented as its reason. First, the pyloric gland mucosa regenerating from injuries by immunization was exposed to the divided doses of x-rays. Second, the marked requirement of gastrin secretion attributable to severe injuries of parietal cell mass by immunization and local x-irradiation acted as a promoting factor on the induction of gastric carcinoma by x-ray for a long time through the trophic effects on the pyloric gland.

    AIM: To establish an experimental animal model of chronic gastritis in a short term and to investigate the effects of several potential inflammation-inducing factors on rat gastric mucosa.METHODS: Twenty-four healthy, male SD rats were treated with intragastric administration of 600 mL/L alcohol, 20mmol/L sodium deoxycholate and 0.5 g/L ammonia (factor A), forage containing low levels of vitamins (factor B), and/or indomethacin (factor C), according to an L8(27)orthogonal design. After 12 wk, gastric antral and body mucosae were pathologically examined.RESULTS: Chronic gastritis model was successfully induced in rats treated with factor A for 12 wk. After the treatment of animals, the gastric mucosal inflammation was significantly different from that in controls, and the number of pyloric glands at antrum and parietal cells at body were obviously reduced (P<0.01). Indomethacin induced gastritis but without atrophy, and short-term vitamin deficiency failed to induce chronic gastritis and gastric atrophy, In addition,indomethacin and vitamin deficiency had no synergistic effect in inducing gastritis with the factor A. No atypical hyperplasia and intestinal metaplasia in the gastric antrum and body were observed in all rats studied.CONCLUSION: Combined intragastric administration of 600 mL/L alcohol, 20 mmol/L sodium deoxycholate and 0.5 g/L ammonia induces chronic gastritis and gastric atrophy in rats. Indomethacin induces chronic gastritis only.The long-term roles of these factors in gastric inflammation and carcinogenesis need to be further elucidated.

    Full Text Available Background: Studies suggest that nuclear factor kappa-B (NFκB activation may be a critical event in the production of proinflammatory molecules in Helicobacter pylori-associated gastritis. Materials and Methods: This study examines the expression and activity of NFκB in situ in antral biopsies of 42 consecutive patients with immunohistochemical techniques. Results: NFκB was highly expressed in the gastric epithelial cells. The number of cells showing activated NFκB correlated with the activity of gastritis (P < 0.05, a measure of neutrophil influx, whereas no correlation was found with the chronicity of inflammation, a measure of the presence of mononuclear inflammatory cells. There was also a strong inverse association with the presence and grade of atrophy. Conclusion: This correlation is direct evidence of the importance of NFκB dependent signal transduction for neutrophil influx in gastritis. The role of NFκB appears to be only in the initial stages of gastritis, there is no role for the molecule in the development of chronic inflammation or atrophy.

    Full Text Available BACKGROUND: The aim of this study was to investigate the interaction effects of pri-let-7a-1 rs10739971 with pepsinogen C (PGC and excision repair cross complementing group 6 (ERCC6 gene polymorphisms and its association with the risks of gastric cancer and atrophic gastritis. We hoped to identify miRNA polymorphism or a combination of several polymorphisms that could serve as biomarkers for predicting the risk of gastric cancer and its precancerous diseases. METHODS: Sequenom MassARRAY platform method was used to detect polymorphisms of pri-let-7a-1 rs10739971 G → A, PGC rs4711690 C → G, PGC rs6458238 G → A, PGC rs9471643 G → C, and ERCC6 rs1917799 in 471 gastric cancer patients, 645 atrophic gastritis patients and 717 controls. RESULTS: An interaction effect of pri-let-7a-1 rs10739971 polymorphism with ERCC6 rs1917799 polymorphism was observed for the risk of gastric cancer (P interaction = 0.026; and interaction effects of pri-let-7a-1 rs10739971 polymorphism with PGC rs6458238 polymorphism (P interaction = 0.012 and PGC rs9471643 polymorphism (P interaction = 0.039 were observed for the risk of atrophic gastritis. CONCLUSION: The combination of pri-let-7a-1 rs10739971 polymorphism and ERCC6 and PGC polymorphisms could provide a greater prediction potential than a single polymorphism on its own. Large-scale studies and molecular mechanism research are needed to confirm our findings.

    Background Spleen in Traditional Chinese Medicine (TCM) is not actually the spleen in the anatomic sense designated in western medicine because its functions basically belong to the physiological category of digestive system in modern medicine, and it represents a macroscopic concept of digestion, absorption and nutrition metabolism. Spleen deficiency syndrome refers to the clinical phenomena such as hypofunction of digestion, absorption and nutrition metabolism. By integrating TCM with modern medicine , this paper is intended to explore the pathological basis of classification of spleen deficiency in chronic gastritis.Method By means of optical microscope, scanning electron microscope (SEM), transmission electron microscope (TEM) and histochemical staining, we conducted histopathological and subcellular ultrastructural (nuclei and mitochondrial) analysis of gastric mucosa of 188 patients of spleen deficiency, and that of 42 voluntary blood donors without clinical symptoms. Results The gastric mucosa of patients with spleen Qi deficiency (SQD) and spleen yang deficiency (SyangD) could either be affected by organic lesion (type G-occurring on the basis of chronic superficial gastritis (CSG), chronic atrophic gastritis (CAG)) or unaffected (type F-chiefly belonging to functional indigestion); spleen yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS) both occurred on the basis of CSG and CAG; and the degree of mucosa inflammatory cells infiltration, the degree of decrease in glands propria, and the incidence of IMⅡb in CSG and CAG were more serious than those of G-SQD and G-SyangD, P<0.05-0.01.Conclusion Spleen deficiency syndrome is likely to occur on the basis of organic lesion of gastric mucosa (disease with symptoms of both CSG or CAG and spleen deficiency symptoms), as well as on the basis of inorganic lesion of gastric mucosa (nondisease with symptoms, which is, despite spleen deficiency symptoms, there is no CSG or CAG).

    Background Most of the studies on traditional Chinese medicine (TCM)‘spleen’deficiency syndrome in the recent 30 years were conducted only on the basis of single functional index, neglecting the study on the pathophysiologic internal relationship between spleen deficiency syndrome and gastric diseases in modern medicine. But it was at the subcellular molecular biological level that we explored the pathophysiologic basis of classification of spleen deficiency in chronic gastritis by detecting the bioactive substances in gastric mucosa nuclei and mitochondria. Methods By means of optical microscope, scanning electron microscope (SEM), transmission electron microscopy (TEM) and histochemical staining, we conducted histopathological, subcellular ultrastructural analysis and nuclei and mitochondrial ultrastructural analysis of gastric mucosa of 188 spleen deficiency patients and of 42 voluntary blood donors. At the same time, bioactive substances were measured by means of X-ray energy dispersive analysis system (EDAX) image analysis system, radioimmunoassay method and chemiluminescence method. Results The content of cAMP, superoxide dismutase (SOD), Zn and Cu in gastric mucosa, and the content of Zn and Cu in mitochondria decreased progressively in order of groups: healthy control (HC), spleen Qi deficiency without organic lesion (F-SQD), spleen Yang deficiency without organic lesion (F-SyangD), disease without symptoms group, spleen Qi deficiency with organic lesion (G-SQD), spleen Yang deficiency with organic lesion (G-SyangD), spleen Yin deficiency (SyinD) and spleen deficiency with Qi stagnation (SDQS), chronic spleen deficiency gastritis (CSG) and chronic atrophic gastritis (CAG); decreased in order of HC, intestinal metaplasia (IM)Ⅰa, IMⅠb, IMⅡa and IMⅡb, P<0.05. The content of DNA, Zn and Cu in nuclei progressively increased in order mentioned above, P<0.05.Conclusions The quantitative changes of gastric mucosal cAMP, SOD, Zn, Cu, of mitochondrial Zn

    AIM: To determine the biological activity of Helicobacter pylori (Hpylori) lipopolysaccharide (H-LPS) and understand pathological correlation between H-LPS and human chronic gastritis and peptic ulcer.METHODS: H-LPS of a clinical Hpylori strain and LPS of Escherichia coli strain O55:B5 (E-LPS) were extracted by phenol-water method. Biological activities of H-LPS and E-LPS were detected by limulus lysate assay, pyrogen assay,blood pressure test and PBMC induction test in rabbits,cytotoxicity test in NIH 3T3 fibroblast cells and lethality test in NIH mice. By using self-prepared rabbit anti-H-LPS serum as the first antibody and commercial HRP-labeled sheep anti-rabbit sera as the second antibody, H-LPS in biopsy specimens from 126 patients with chronic gastritis (68 cases) or gastric ulcer (58 cases) were examined by immunohistochemistry.RESULTS: Fibroblast cytotoxicity and mouse lethality of H-LPS were weaker than those of E-LPS. But the ability of coagulating limulus lysate of the two LPSs was similar (+/0.5 ng/mL). At 0.5 h after H-LPS injection, the blood pressures of the 3 rabbits rapidly declined. At 1.0 h after H-LPS injection, the blood pressures in 2 of the 3 rabbits fell to zero causing death of the 2 animals. For the other one rabbit in the same group, its blood pressure gradually elevated. At 0.5 h after E-LPS injection, the blood pressures of the three rabbits also quickly declined and then maintained at low level for approximately 1.0 h. At 0.5 h after injection with H-LPS or E-LPS, PBMC numbers of the rabbits showed a remarkable increase. The total positivity rate of H-LPS from 126 biopsy specimens was 60.3%(76/126). H-LPS positivity rate in the biopsy specimens from chronic gastritis (50/68, 73.5%) was significantly higher than that from gastric ulcer (26/58, 44.8%) (X2=10.77,P<0.01). H-LPS positivity rates in biopsy specimens from chronic superficial gastritis (38/48, 79.2%) and chronic active gastritis (9/10, 90.0%) were significantly higher than

    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)

The purpose of the present research was to compare the intensity of lymphoid CD95 immunoexpression in 15 cases of H. pylori-related chronic gastritis and 15 gastric MALT lymphomas. CD95 (anti-CD95 was detected by an immunoperoxidase technique in paraffin sections using the catalyzed amplification system. Graduation of reaction intensity (percentage of CD95-positive cells was semiquantitative, from 1+ to 4+. Nine cases of chronic gastritis were 4+, five 2+ and one 1+. Three lymphomas were 4+, three 3+, four 2+, four 1+, and one was negative. Although 14 of 15 lymphomas were positive for CD95, the intensity of the reaction was significantly weaker compared to that obtained with gastric tissue for patients with gastritis (P = 0.03. The difference in CD95 immunoexpression does not seem to be useful as an isolated criterion in the differential diagnosis between chronic gastritis and MALT lymphomas since there was overlapping of immunostaining patterns. However, it suggests the possibility of a pathogenetic role of this apoptosis-regulating protein in MALT lymphomas.

    Full Text Available Abstract Background The aim of this study is evaluating the correlation of postprandial fullness with chronic gastritis or rapid inflow of gastric content into duodenum, based on double-contrast barium X-ray imaging. Methods 253 healthy subjects who underwent upper gastrointestinal barium X-ray examination were analyzed. Chronic gastritis was judged from mucosal atrophy and hypertrophic thickened folds on barium X-ray images. For the gastric excretion, the tips of barium flow on the single-contrast frontal barium X-ray images of the stomach were classified into four categories; V type (all the barium remained in the stomach, V-H type (some barium had flowed into the duodenum but the tip of barium remained in the proximal half of the duodenal bulb, H-V type (some barium had flowed into the duodenum and the tip of barium was in the distal half of duodenal the bulb, but no barium was observed in the descending part of the duodenum, and H type (some barium had flowed into the descending part of the duodenum. The chi-square test and Cochran-Mantel-Haenzel test were used for evaluation. Results Chronic gastritis was observed in 72 subjects, among which 21 subjects (29.2% presented with postprandial fullness. For the remaining 181 subjects without chronic gastritis, 53 subjects (29.3% complained of postprandial fullness. There is no significant correlation between chronic gastritis and postprandial fullness (p = 0.973. For the rapid flow of gastric content into duodenum, all the 253 subjects comprised 136 subjects with V type (in the stomach, 40 subjects with V-H type (in the proximal half of the duodenal bulb, 21 subjects with H-V type (in the distal half of the duodenal bulb, and 56 subjects with H type (in the descending part of the duodenum. Postprandial fullness was present in 30 subjects with V type (22.1%, 9 subjects with V-H type (22.5%, 8 subjects with H-V type (38.1%, and 27 subjects with H type (48.2%. There is a distinct correlation between

    Full Text Available AIM: To investigate the potential therapeutic effect of exopolysaccharide (EPS-producing Streptococcus thermophilus (S. thermophilus CRL 1190 fermented milk on chronic gastritis in Balb/c mice.METHODS: Balb/c mice were fed with the fermented milk for 7 d after inducing gastritis with acetyl-salicylic acid (ASA, 400 mg/kg body weight per day for 10 d. Omeprazole was included in this study as a positive therapeutic control. The gastric inflammatory activity was evaluated from gastric histology and inflammation score, number of interleukin-10 (IL-10, interferon-γ (INFγ and tumor necrosis factor-α (TNF-α cytokine-producing cells in the gastric mucosa, and thickness of the mucus layer.RESULTS: Animals receiving treatment with the EPS-producing S. thermophilus CRL 1190 fermented milk showed a conserved gastric mucosa structure similar to that of healthy animals. Inflammation scores of the fermented milk-treated mice were lower than those of mice in the gastritis group (0.2 ± 0.03 vs 2.0 ± 0.6, P < 0.05. A marked decrease in INFγ+ (15 ± 1.0 vs 28 ± 1.2, P < 0.05 and TNF-α+ (16 ± 3.0 vs 33 ± 3.0, P < 0.05 cells and an increase in IL-10+ (28 ± 1.5 vs 14 ± 1.3, P < 0.05 cells compared to the gastritis group, was observed. Also, an increase in the thickness of the mucus gel layer (2.2 ± 0.6 vs 1.0 ± 0.3; 5.1 ± 0.8 vs 1.5 ± 0.4 in the corpus and antrum mucosa, respectively, P < 0.05 compared with the gastritis group was noted. A milk suspension of the purified EPS from S. thermophilus CRL1190 was also effective as therapy for gastritis.CONCLUSION: This study suggests that fermented milk with S. thermophilus CRL 1190 and/or its EPS could be used in novel functional foods as an alternative natural therapy for chronic gastritis induced by ASA.

Mucosal biopsies demonstrated acute and chronic gastritis that was not associated with the presence of Campylobacter pylori

  9. Cyclooxygenase-2 Expression in Chronic Gastritis and Gastric Carcinoma, Correlation with Prognostic Parameters

    International Nuclear Information System (INIS)

    Background: Cyclooxygenase-2 (Cox-2) is the inducible form of cyclooxygenase enzyme. Cox-2 is induced in numerous processes such as cellular growth, differentiation, inflammation and tumorigenesis. Purpose: Assessment of Cox-2 expression in chronic gastritis s and gastric carcinoma. Material and Methods: Sixteen chronic gastritis (CG) and 43 gastric carcinoma cases were subjected to an immunohistochemical approach using anti Cox-2 antibody. Results: All CG cases displayed positive epithelial Cox-2 expression with only 25% positivity for stromal expression. Eighty six percent of gastric carcinoma showed epithelial Cox-2 expression that was significantly correlated with lymph node involvement (p=0.01), advanced stage (p=0.01), high micro vessel density (MVD) (p=0.0001), vascular invasion (p=0.002), peri neural invasion (p=0.0 I) and low apoptotic count (p<0.0001). Stromal Cox-2 expression was seen in 79% of gastric carcinoma cases and was significantly associated with low apoptotic count (p=0.0007), vascular invasion (p=0.001) and high micro vessel density (MVD) (p=0.0003). Only stromal Cox2 expression was significantly higher in gastric carcinoma than chronic gastritis (p=0.0001). Conclusions: Cox-2 appears to be involved in gastric carcinoma progression as it promotes angio genesis, suppresses apoptosis and facilitates invasion and metastasis Double expression of Cox-2 in gastric carcinoma epithelium and stroma and significant association between them demonstrate a paracrine cross effect between stromal and malignant epithelium

  10. Helicobacter pylori detection in chronic gastritis: a comparison of staining methods

    International Nuclear Information System (INIS)

    Background: Helicobacter pylori is an important cause of chronic gastritis, gastric ulceration and gastric malignancies as gastric carcinoma and MALT lymphoma. Its definitive diagnosis is based on histopathology. Routine H and E stain is not very effective in its detection, immune-stains and fluorescent stains are costly. Need for simple cheap and sensitive stain has always been a topic of hot debate and extensive research. Method: paraffin embedded blocks of all adult patients diagnosed as chronic gastritis/gastric ulceration with no accompanying gastric pathology as hypertrophic gastropathys, and neoplasias were taken into study. Three sections of 4 micron were cut and stained with routine H and E, Giemsa, and Cresyl fast violet. Results: Total number of patients was 50. Out of these 37 (74%) were males and 13 (26%) were females. Mean age of the patients was 50.4 years. Thirty-four percent (34%) were positive in normal H and E stain, 68% were positive in Giemsa and 76% were positive in Cresyl fast violet. Conclusion: Cresyl fast violet is a good stain for diagnosis of H. pylori gastritis. (author)

    Full Text Available This study was aimed to describe the endoscopic picture and laboratory findings in children with chronic abdominal pain and to determine the utility of nodular gastritis in diagnosing HPI in these patients. This prospective study was done between November, 2004 and May, 2007. A total of 70 patients (36 male and 34 female aged 3-14 years, underwent upper endoscopy. H-pylori infection was diagnosed when both urease test and histology were positive for the infection. Seventy percent (n = 49 of them were diagnosed to have endoscopic nodular gastritis. HPI was confirmed in 33 (47.1% of 70 patients. The endoscopic antral nodularity had a sensitivity of 100%, specificity of 56.8%, positive predictive value of 67.3%, negative predictive value of 100% and a positive LR of 2.32 for diagnosis of HPI. It may be recommended that if nodular gastritis observed in a pediatric patient with chronic abdominal pain he/she should be investigated to exclude HPI otherwise no further work up is necessary to confirm HPI.

    [Objective] Atrophic gastritis is a disease with intestinal metaplasia, and reveals that human immune system (cells, body fluids, partial immunity) is in a low state. "Spleen is a defense banier to pathogenic qi," "if spleen function maintains normal all the time, human body will not be ill," that reveals the immune role of the spleen. In modern medicine, spleen is regarded as immune response and immune material base, one of the barriers of the human immune system. Because proteomics is not anatomical concept of organs and tissues etc., but involves in certain aspects' alteration in biochemistry and internal relationship of disease processes. These physiological and pathological viewpoints are in coincident with TCM holism. From the angle of immunity micro-molecule proteome, atrophic gastritis spleen-qi deficiency substance will be elaborated.%萎缩性胃炎(AG)是人体整体免疫力(细胞、体液、局部免疫)低下,多种因素长期作用而表现胃局部、常伴肠化的病症.“脾为之卫”、“四季脾旺不受邪”,表现脾的免疫防卫作用,现代医学也认为脾是免疫应答和产生免疫效应物质的重要基地,人体免疫系统的屏障之一.由于蛋白质组学的研究不是从器官组织的解剖学定位出发,强调生物化学某一环节的改变和疾病过程的内在联系,与中医学整体的生理病理观有更多的切合点,本文旨在从免疫小分子蛋白质组表达规律的角度观察与AG脾气虚证的相关性.

    Full Text Available INTRODUCTION: Helicobacter pylori is one of the main causes of gastroduodenal diseases, such as chronic gastritis and peptic ulcer. It has been shown that eosinophils increase in the stomach in H. pylori infection. Eosinophilic cationic protein (ECP is a cytotoxic molecule secreted by the activated eosinophils. However, there are no sufficient data about the role of ECP in H. pylori infection and its effect on ulcer development. In this study we investigated the gastric eosinophilic infiltration, gastric juice and serum ECP levels in patients with chronic gastritis and gastric ulcer associated with H. pylori.

    Full Text Available In Traditional Chinese Medicine (TCM, tongue diagnosis (TD has been an important diagnostic method for the last 3000 years. Tongue coating can be used as a very sensitive marker to determine the progress of chronic gastritis. Therefore, the scientific, qualitative, and quantitative study for the pathophysiologic basis of tongue coating (TC emerged as a major direction for the objective research of TD. In our current report, we used GC/MS technology to determine the potential changes of metabolites and identify special metabolic biomarkers in the TC of H. pylori infected chronic gastritis patients. Four discriminative metabolites were identified by GC/MS between the TC of H. pylori infection (G+H and without H. pylori infection (G-H patients: ethylene, cephaloridine, γ-aminobutyric acid, and 5-pyroglutamic acid, indicating that changes in amino acid metabolism are possibly involved in the formation of TC, and the amino acid metabolites are part of the material components of TC in G+H patients.

    AIM: To investigate the influences of bile reflux on profiles of gastric mucosal lesions in patients with dyspepsia or chronic gastritis.METHODS: A total of 49 patients diagnosed with dyspepsia and chronic gastritis underwent 24-h ambulatory andsimultaneous monitoring of intragastric bilirubin absorbance and pH values, and then they were divided into bile refluxpositive group and bile reflux negative group. Severity of pathological changes in gastric mucosa including activeinflammation, chronic inflammation, intestinal metaplasia, atrophy and dysplasia as well as Helicobacter pylori (H pylori) infection at the corpus, incisura and antrum were determined respectively according to update Sydney system criteria. The profiles of gastric mucosal lesions in the two groups were compared, and correlations between time-percentage of gastric bilirubin absorbance >0.14 and severity of gastric mucosal lesions as well as time-percentage of gastric pH >4 were analyzed respectively. RESULTS: Thirty-eight patients (21 men and 17 women, mean age 44.2 years, range 25-61 years) were found existing with bile reflux (gastric bilirubin absorbance >0.14) and 11 patients (7 men and 4 women, mean age 46.2 years,range 29-54 years) were bile reflux negative. In dyspepsia patients with bile reflux, the mucosal lesions such as active inflammation, chronic inflammation, intestinal metaplasia, atrophy or H pylori infection in the whole stomach, especially in the corpus and incisura, were significantly more severe than those in dyspepsia patients without bile reflux. Moreover, the bile reflux time was well correlated with the severity of pathological changes of gastric mucosa as well as H pylori colonization in the near-end stomach, especially in the corpus region. No relevance was found between the time of bile reflux and pH >4 in gastric cavity. CONCLUSION: Bile reflux contributes a lot to mucosal lesions in the whole stomach, may facilitate H pylori colonization in the corpus region

    Helicobacter pylori persistence in patients with chronic gastritis is associated with a complex of nonspecific structural reactions, the type of these reactions correlates with the severity of infection: catarrhal fibrotic changes in the gastric mucosa predominate in cases with manifest colonization, while the absence of H. pylori is associated with predominance of fibrotic process. Analysis of the incidence of some pathomorphological phenomena (degeneration, atrophy, metaplasia, and dysplasia of the surface epithelium) shows no relationship between the presence of H. pylori and colonization intensity. In all patients with chronic hepatitis, the gastric mucosa is involved in the pathological process; fibrosis (gastropathy) was the most common process. No appreciable correlations between the structural changes and hepatitis activity and the presence of H. pylori were detected. PMID:26899845

    H. pylori (Hp) -induced atrophic gastritis is a well-known risk factor for the development of gastric cancer. Whether Hp eradication can prevent or retard the progress of atrophy and metaplasia has been the topic of numerous studies but the subject remains controversial. Recently, the increased expression of ornithine decarboxylase (ODC), gastrin and cyclooxygenase (COX)-2 has been shown to be increased in premalignant lesions in gastric mucosa and to play an essential role in the malignant transformation. The aim of the study is to assess the effect of eradication therapy on atrophic gastritis and analyze the gene expression for ODC, COX-2 and gastrin in gastric mucosa after succesful eradication in patients with atrophic gastritis. Twenty patients with chronic atrophic gastritis including both corpus and antrum of the stomach were included in this study. Four antral mucosal biopsy specimens were obtained from antrum and four from corpus. The histopathologic evaluation of gastritis was based on Sydney classification of gastritis. All patients were Hp positive based on the [13C] urea breath test (UBT) and the presence of anti-Hp IgG and anti-CagA-antibodies detected by ELISA. The patients were then eradicated with triple therapy consiting of omeprazol (2 x 20 mg), amoxycillin (2 x 1 g) and clarithromycin (2 x 500 mg) for seven days and vitamin C 1 g/day for three months. In gastric mucosal samples obtained from the antrum and corpus before and after eradication, the mRNA expression for ODC, COX-2, and gastrin was assessed by reverse-transcription polymerase chain reaction (RT-PCR). In all patients the gastric secretory analysis was performed by measuring gastric acid output and serum gastrin levels. After triple therapy the successful eradication assessed by UBT was observed in 95% of patients. In 45% of patients the infection with CagA-positive Hp strain was observed. Three months after eradication a significant reduction in the gastric activity (neutrophilic

    AIM: To investigate the expression of different cytokeratins (CKs) in gastric epithelium of adult patients with chronic gastritis infected with Helicobacter pylori(H pylori) cagA + strains.METHODS: The expression of CK 7, 8, 18, 19 and 20 was studied immunohistochemically in antral gastric biopsies of 84 patients. All the CKs were immunostained in cagA +H pylori gastritis (57 cases), non-Hpylori gastritis (17 cases) and normal gastric mucosa (10 cases).RESULTS: In cagA+ Hpylori gastritis, CK8 was expressed comparably to the normal antral mucosa from surface epithelium to deep glands. Distribution of CK18 and CK 19 was unchanged, i.e. transmucosal,but intensity of the expression was different in foveolar region in comparison to normal gastric mucosa. Cytokeratin 18 immunoreactivity was significantly higher in the foveolar epithelium of H pylori-positive gastritis compared to both Hpylori-negative gastritis and controls.On the contrary, decrease in CK19 immunoreactivity occurred in foveolar epithelium of H pylori-positive gastritis. In both normal and inflamed antral mucosa without H pylori infection, CK20 was expressed strongly/ moderately and homogenously in surface epithelium and upper foveolar region, but in H pylori-induced gastritis significant decrease of expression in foveolar region was noted. Generally, in both normal antral mucosa and H pylori-negative gastritis, expression of CK7 was not observed, while in about half cagA+ H pylori-infected patients, moderate focal CK7 immunoreactivity of the neck and coiled gland areas was registered, especially in areas with more severe inflammatory infiltrate.CONCLUSION: Alterations in expression of CK 7, 18,19 and 20 together with normal expression of CK8 occur in antral mucosa of H pylori-associated chronic gastritis in adult patients infected with cagA+ strains. Alterations in different cytokeratins expression might contribute to weakening of epithelial tight junctions observed in H pylori-infected gastric mucosa.

    To record gastric peristalsis using a conventional scintigraphic gastric emptying test the frame rate was increased to 1 frame per 3 s at 10, 30, and 50 min postprandially. The gastric contraction frequency was obtained from the first harmonic of a Fourier transform of a gastric region of interest (ROI) curve. The propagation of gastric contractions was better revealed from computed functional images of the phase and amplitude distribution as compared with the multiple scintigraphic images. The maximal count-rate changes per pixel were calculated as an estimate of the most prominent regional contractile activity of the gastric wall. Among 12 patients with chronic gastritis the group with more severe dyspeptic complaints (n = 6) had significantly higher count-rate changes per pixel when compared with the group with minor complaints (20.0, 21.1 and 14.2 vs 12.9, 12.0, and 10.4 counts/pixel X s at 10, 30, and 50 min. respectively; p < 0.05). The mean half-times of gastric emptying (61, SD 11 vs 54, SD 13 min) and the mean gastric contraction frequencies (2.99, SD 0.19; 3.09, SD 0.33; 3.07, SD 0.10 vs 3.15, SD 0.15; 3.17, SD 0.13; 3.23, SD 0.20 cycles/min at 10, 30, and 50 min, respectively) did not show significant differences between both groups. Our preliminary results agree with the hypothesis of the occurrence of more powerful, nonexpulsive gastric-wall contractions in patients with more severe dyspeptic complaints. Hence, additional quantification of gastric motility allowed a more detailed evaluation of gastric-motor-activity disorders that were for so long not accessible to conventional gastric-emptying tests.

    AIM: To compare Helicobacter pyloriinfection and gastric mucosal histological features of gastric ulcer patients with chronic gastritis patients in different age groups and from different biopsy sites.METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of gastric ulcer and chronic gastritis patients. Giemsa staining, improved Toluidine-blue staining and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylineosin staining was used for the histological diagnosis of activity of H pylori infection, mucosal inflammation,glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System.RESULTS: Total rate of H pylori infection, mucosal inflammation, activity of H pylori infection, glandular atrophy and intestinal metaplasia in 3 839 gastric ulcer patients (78.5%, 97.4%, 82.1%, 61.1% and 64.2%,respectively) were significantly higher than those in 4 102chronic gastritis patients (55.0%, 90.3%, 56.2%, 36.8%,and 37.0%, respectively, P<0.05). The rate of H pylori colonization of chronic gastritis in <30 years, 31-40 years,41-50 years, 51-60 years, 61-70 years and >70 years age groups in antrum was 33.3%, 41.7%, 53.6%, 57.3%,50.7%, 43.5%, respectively; in corpus, it was 32.6%,41.9%, 53.8%, 60.2%, 58.0%, 54.8%, respectively; in angulus, it was 32.4%, 42.1%, 51.6%, 54.5%, 49.7%,43.5%, respectively. The rate of Hpyloricolonization of gastric ulcer in <30 years, 31-40 years, 41-50 years,51-60 years, 61-70 years and >70 years age groups in antrum was 60.5%, 79.9%, 80.9%, 66.8%, 59.6%, 45.6%,respectively; in corpus, it was 59.7%, 79.6%, 83.6%,80.1%, 70.6%, 59.1%, respectively; in angulus, it was61.3%, 77.8%, 75.3%, 68.8%, 59.7%, 45.8%,respectively.

    AIM: To evaluate the association between polymorphisms XRCC1 Arg194Trp and Arg399Gln and XRCC3Thr241Met and the risk for chronic gastritis and gastric cancer, in a Southeastern Brazilian population.METHODS: Genotyping by PCR-RFLP was carried out on 202 patients with chronic gastritis (CG) and 160 patients with gastric cancer (GC), matched to 202 (C1) and 150(C2) controls, respectively.RESULTS: No differences were observed among the studied grou ps with regard to the genotype distribution of XRCC1 codons 194 and 399 and of XRCC3 codon 241. However, the combined analyses of the three variant alleles (194Trp, 399Gln and 241Met) showed an increased risk for chronic gastritis when compared to the GC group. Moreover, an interaction between the polymorphic alleles and demographic and environmental factors was observed in the CG and GC groups. XRCC1 194Trp was associated with smoking in the CG group,while the variant alleles XRCC1 399Gln and XRCC3241Met were related with gender, smoking, drinking and H pylori infection in the CG and GC groups.CONCLUSION: Our results showed no evidence of a rela-tionship between the polymorphisms XRCC1Arg194Trp and Arg399Gln and XRCC3 Thr241Met and the risk of chronic gastritis and gastric cancer in the Brazilian population, but the combined effect of these variants may interact to increase the risk for chronic gastritis,considered a premalignant lesion. Our data also indicate a gene-environment interaction in the susceptibility to chronic gastritis and gastric cancer.

    were examined using anti-Brdu immunohistoche-mical staining and flow cytometry. Results (1) H. pylori turned to negative in all mice received eradication therapy. Significant improvement of chronic active gastritis was observed after eradication of H. pylori in both group A and B, no atrophic changes was seen at any time interval in group A, whereas in group B, atrophic changes were seen 12 months after H. pylori infection and no significant change of the degree of atrophy was observed 3 and 6 months after eradication of H. pylori. (2) The cell kinetic indexes (S%, PI and LI) in the experimental group before eradication of H. pylori were significantly higher than those in the control at any time interval (P 0.05 ). Conclusion The study suggests that eradication of H. pylori can improve gastric mucosal inflammation and epithelial cell kinetics of the sto-mach, and early treatment can prevent formation of mucosal atrophy. Once atrophy was established, eradica-tion of H. pylori has no effects on the return to normal but may prevent its progress.

    AIM: To study the effect of mucilage obtained from cladodes of Opuntia ficus-indica (Cactaceae) on the healing of ethanol-induced gastritis in rats.METHODS: Chronic gastric mucosa injury was treated with mucilage (5 mg/kg per day) after it was induced by ethanol. Lipid composition, activity of 5'-nucleotidase (a membrane-associated ectoenzyme) and cytosolic activities of lactate and alcohol dehydrogenases in the plasma membrane of gastric mucosa were determined.Histological studies of gastric samples from the experimental groups were included.RESULTS: Ethanol elicited the histological profile of gastritis characterized by loss of the surface epithelium and infiltration of polymorphonuclear leukocytes.Phosphatidylcholine (PC) decreased and cholesterol content increased in plasma membranes of the gastric mucosa. In addition, cytosolic activity increased while the activity of alcohol dehydrogenases decreased. The administration of mucilage promptly corrected these enzymatic changes. In fact, mucilage readily accelerated restoration of the ethanol-induced histological alterations and the disturbances in plasma membranes of gastric mucosa, showing a univocal anti-inflammatory effect.The activity of 5'-nucleotidase correlated with the changes in lipid composition and the fluidity of gastric mucosal plasma membranes.CONCLUSION: The beneficial action of mucilage seems correlated with stabilization of plasma membranes of damaged gastric mucosa. Molecular interactions between mucilage monosaccharides and membrane phospholipids,mainly PC and phosphatidylethanolamine (PE), may be the relevant features responsible for changing activities of membrane-attached proteins during the healing process after chronic gastric mucosal damage.

    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.

    Aging is a multifactorial universal process and constitutes the most important risk factor for chronic-degenerative diseases. Although it is a natural process, pathological aging arises when these changes occur quickly and the body is not able to adapt. This is often associated with the generation of reactive oxygen species (ROS), inflammation, and a decrease in the endogenous antioxidant systems, constituting a physiopathological state commonly found in chronic-degenerative diseases. At the testicular level, aging is associated with tissue atrophy, decreased steroidogenesis and spermatogenesis, and sexual behavior disorders. This situation, in addition to the elevated generation of ROS in the testicular steroidogenesis, provides a critical cellular environment causing oxidative damage at diverse cellular levels. To assess the effects of a reduction in the levels of ROS, thiamine pyrophosphate (TPP) was chronically administered in senile Wistar rats. TPP causes an activation of intermediate metabolism routes, enhancing cellular respiration and decreasing the generation of ROS. Our results show an overall decrease of atrophic histological changes linked to aging, with higher levels of serum testosterone, sexual activity, and an increase in the levels of endogenous antioxidant enzymes in TPP-treated animals. These results suggest that TPP chronic administration decreases the progression of age-related atrophic changes by improving the intermediate metabolism, and by increasing the levels of antioxidant enzymes.

  12. Breath test to diagnose the presence of Helicobacter pylori, the causative agent of active chronic gastritis and ulcers

    International Nuclear Information System (INIS)

    In Brazil almost 80% of the population presents the bacterium Helicobacter pylori, considered to be the causative agent of active chronic gastritis and ulcers. This does not mean that all of these people will suffer gastritis or ulcers, but it is highly probable. The usual diagnostic procedure used a microbiological culture in mucus biopsy specimens collected during gastroscopy, an invasive method. The problem was to find a non-invasive, easy, fast and efficient procedure to diagnose this bacterium. The nuclear technique applied was liquid scintillation, a suitable technique to measure the low energy β emission of 14C. This was the best method available at the time to develop and establish the test. In order to develop a non-invasive test to diagnose H. pylori, research was carried out with doctors from the Department of Gastroenterology at the School of Medicine of the Federal University of Minas Gerais. This research applied a radiochemical method using 14C, a radioisotope of carbon. The patient's control breath sample was obtained after a 12 hour fast. Then a standard meal was offered to delay gastric emptying, after which the patient drank a determined amount of urea labelled with 14C in water. Breath samples were collected at 10, 15, 30 and 60 minutes in a hyaline-ethanol solution with a pH (acid) indicator. If the bacteria were present, the labelled urea would be metabolized and the 14C would be eliminated as 14CO2 by exhalation; otherwise the 14C would be eliminated through the faeces. This 14C urea breath test was applied in around 5000 participants and the results were compared with results obtained through culture

    Chronic urticaria (CU) is defined as the occurrence of spontaneous wheals for a duration of more than 6 weeks and is the most frequent skin disease, with prevalence ranging between 15 and 25%, and is a seriously disabling condition, with social isolation and mood changes causing a significant degree of dysfunction and quality of life impairment to many patients. The main clinical features of CU are the repeated occurrence of transient eruptions of pruritic wheals or patchy erythema on the skin that last less than 24 hours and disappear without sequelae. CU is often defined as chronic idiopathic urticaria (CIU) because the causes of CU remain unknown in the great majority (70-95%) of patients. Drugs, food, viruses, alimentary conservative substances or inhalant substances often seem to be involved in determining CIU skin flare. Despite a general agreement that bacteria infections and parasitic infestations can be involved in the pathogenesis of CIU, proven evidence of these relationships is lacking. The aim of the present study is to evaluate the prevalence of Helicobacter pylori (Hp) infection, and the extension and severity of gastritis in a group of CIU patients compared to controls and to evaluate the effectiveness of eradication of Hp on the CIU symptomatology, and the role of Hp infection in pathogenesis of CIU.

    In spite of its high incidence, not much is known about the etiology of chronic urticaria. We performed gastroscopic evaluation of 10 patients in whom no cause for chronic urticaria had been found. In 8 of these 10 patients, Helicobacter pylori was identified in the gastric mucosa. The chronic urticarial lesions disappeared within a few days after starting therapy with amoxicillin and omeprazol. PMID:8868453

  16. The surgical treatment of chronic gastric atony following Roux-Y diversion for alkaline reflux gastritis

    International Nuclear Information System (INIS)

    Symptoms of severe nausea, vomiting, abdominal pain, and frequent bezoars, as well as objective gastric retention, can occur following Roux-Y biliary diversion for alkaline reflux gastritis. Medical therapy and prokinetic drugs have proven ineffective. This review evaluates 37 patients who underwent further gastric resection from 1979 to 1987 to improve gastric emptying and resolve symptoms. Fifteen patients underwent perioperative radionuclide solid-food gastric emptying studies. Seventy-three per cent (27 of 37 patients) of the patients who underwent further gastric resection (70% to 95%) had a satisfactory postoperative response. Twenty patients were graded Visick 1 or 2 and 7 Visick-3 patients, although much improved, still had some symptoms of gastroparesis. Twenty-seven per cent (10 of 37 patients) failed to improve and underwent completion total gastrectomy. Overall, 70% of this group had almost complete resolution of their symptoms. Three of 10 patients were considered ''failures'' due to postprandial pain in 1 and early vasomotor dumping in 2. Of the 10 patients who failed initial revisional surgery, 7 underwent a 70% to 80% subtotal gastric resection (STG) and 3 patients underwent 85% to 95% extensive resection (EXT.G.). Of the 15 patients who underwent perioperative radionuclide evaluation, a mean two-hour gastric retention of 61.4% +/- 4% (SEM) decreased to 25% +/- 4% following further gastric resection. Eight patients were in the STG group and seven patients were in the EXT.G group. Following STG, mean two-hour gastric retention of 58.2% +/- 3.5% decreased to 38% +/- 3% (p less than 0.05). In seven patients who underwent EXT.G, mean two-hour retention of 65% +/- 4% decreased to 10% +/- 2.5% (p less than 0.005). EXT.G resulted in normal gastric emptying and few late failures

    Full Text Available Helicobacter pylori infection reprograms host gene expression and influences various cellular processes, which have been investigated by cDNA microarray using in vitro culture cells and in vivo gastric biopsies from patients of the Chronic Abdominal Complaint. To further explore the effects of H. pylori infection on host gene expression, we have collected the gastric antral mucosa samples from 6 untreated patients with gastroscopic and pathologic confirmation of chronic superficial gastritis. Among them three patients were infected by H. pylori and the other three patients were not. These samples were analyzed by a microarray chip which contains 14,112 cloned cDNAs, and microarray data were analyzed via BRB ArrayTools software and Ingenuity Pathways Analysis (IPA website. The results showed 34 genes of 38 differentially expressed genes regulated by H. pylori infection had been annotated. The annotated genes were involved in protein metabolism, inflammatory and immunological reaction, signal transduction, gene transcription, trace element metabolism, and so on. The 82% of these genes (28/34 were categorized in three molecular interaction networks involved in gene expression, cancer progress, antigen presentation and inflammatory response. The expression data of the array hybridization was confirmed by quantitative real-time PCR assays. Taken together, these data indicated that H. pylori infection could alter cellular gene expression processes, escape host defense mechanism, increase inflammatory and immune responses, activate NF-κB and Wnt/β-catenin signaling pathway, disturb metal ion homeostasis, and induce carcinogenesis. All of these might help to explain H. pylori pathogenic mechanism and the gastroduodenal pathogenesis induced by H. pylori infection.

    AIM: The role of Helicobacter pylori (H pylori) infection in gastric acid secretion of patients with chronic gastritisremains controversial. This study was designed to elucidate the effect of H pylori on H+/K+-ATPase activities in gastric biopsy specimens.METHODS: Eighty-two patients with chronic gastritis who had undergone upper endoscopy were included in this study. H pylori infection was confirmed by rapid urease test and histology. Gastric H+/K+-ATPase activities and serum gastrin concentrations were measured by an enzymatic method and radioimmunoassay, respectively. For those patients who received triple therapy for eradicating H pylori, changes in the activity of gastric H+/K+-ATPase and serum gastrin levels were also measured. RESULTS: The mean gastric H+/K+-ATPase activity in H pyloripositive group (42 patients) was slightly higher than thatin H pylori-negative group (29 patients) (169.65±52.9 and eradication of H pylori, the gastric H+/K+-ATPase activities slightly decreased compared to prior therapy (165.03±59.50 The mean basal gastrin concentration was slightly higher in H pylori-positive patients than in H pylori-negative patients (87.92±39.65 pg/mL vs75.04± 42.57 pg/mL, P= 0.228). The gastrin levels fell significantly after the eradication of Hpylori. (Before treatment 87.00±30.78 pg/mL, aftertreatment 64.73±18.96 pg/mL, P = 0.015).CONCLUSION: Gastric H+/K+-ATPase activities are not associated with H pylori status in patients with chronicgastritis.

    Seven illustrative cases of gastritis of the herniated stomach in patients with sliding esophageal hiatus hernia are reported. Five had superficial gastritis (three mild, one moderate and one severe); two had atrophic gastritis. Gastritis was present in two patients whose mucosa appeared normal at esophagoscopy. Interstitial hemorrhage into the lamina propria was present in four of the seven biopsy specimens. The possibility that interstitial hemorrhage may be related to the development of gastric erosions is considered. The pathogenesis of this form of gastritis is discussed.

    Objective To study the detailed nature of genomic microevolution during mixed infection with multiple Helicobacter pylori strains in an individual. Design We sampled 18 isolates from a single biopsy from a patient with chronic gastritis and nephritis. Whole-genome sequencing was applied to these isolates, and statistical genetic tools were used to investigate their evolutionary history. Results The genomes fall into two clades, reflecting colonisation of the stomach by two distinct strains, and these lineages have accumulated diversity during an estimated 2.8 and 4.2 years of evolution. We detected about 150 clear recombination events between the two clades. Recombination between the lineages is a continuous ongoing process and was detected on both clades, but the effect of recombination in one clade was nearly an order of magnitude higher than in the other. Imputed ancestral sequences also showed evidence of recombination between the two strains prior to their diversification, and we estimate that they have both been infecting the same host for at least 12 years. Recombination tracts between the lineages were, on average, 895 bp in length, and showed evidence for the interspersion of recipient sequences that has been observed in in vitro experiments. The complex evolutionary history of a phage-related protein provided evidence for frequent reinfection of both clades by a single phage lineage during the past 4 years. Conclusions Whole genome sequencing can be used to make detailed conclusions about the mechanisms of genetic change of H. pylori based on sampling bacteria from a single gastric biopsy.

    Endoscopic visualisation of gastric atrophy is usually not feasible with conventional endoscopy. Magnifying endoscopy is helpful to analyze the subepithelial microvascular architecture as well as the mucosal surface microstructure without tissue biopsy. Using this technique we were able to describe the normal gastric microvasculature pattern and we also identified characteristic patterns in two cases of autoimmune atrophic gastritis.

    Background Gastritis is an important premalignant lesion and recent studies suggested a production of inflammatory cytokine-like C-reactive protein during gastritis. This study aimed to determine any relationship between high sensitive C-reactive protein (hs-CRP) and inflammation activity among patients with gastritis. Methods Demographic and clinical variables of participants were collected by a validated questionnaire. Using histology of the gastric mucosa, Helicobacter pylori status was investigated and serum concentrations of hs-CRP were measured among dyspeptic patients. Correlation between hs-CRP serum levels and inflammation activities was evaluated by logistic regression analysis. The relation between active inflammation and other variables was evaluated by logic link function model. Results Totally 239 patients (56.6% female) were analysed. The prevalence of mild, moderate and severe inflammation activities was 66.5%, 23.8% and 9.6% respectively. Mean ± SD of hs-CRP among men and women were 2.85 ± 2.84 mg/dl and 2.80 ± 4.80 mg/dl (p = 0.047) respectively. Mean ± SD of hs-CRP among patients with H. pylori infection, gland atrophy, metaplasia and dysplasia were 2.83 ± 3.80 mg/dl, 3.52 ± 5.1 mg/dl, 2.22 ± 2.3 mg/dl and 5.3 ± 5.04 mg/dl respectively. Relationship between hs-CRP and inflammation activities (p gastritis, elevated hs-CRP levels may be considered as a predictive marker of changes in gastric mucosa and a promising therapeutic target for patients with gastritis.

    Endogenous, exogenous stress factors can affect on human psychological and neuroendocrine system, and the different character under same stress factors may have different stress response. Excessive stress is an important reason leading to psychosomatic illness. Most refractory chronic gastritis has close relationship with iatrogenic stress. The therapy of chronic gastritis and FD should be used as a treatment to relieve symptoms. It is not necessary to have too much emphasis on anti- Hp, the doctor should pay attention to regulate behavior, give a reasonable interpretation of the disease and avoid iatrogenic trauma of stress for patients in the clinical work, and reduce the incidence of iatrogenic mental illness.%内源性,外源性应激因素都会对人体心理和神经内分泌系统造成影响,在同一应激因素下由于人格不同可能有不同的应激反应.过度的应激是导致心身疾病的重要原因.多数难治性慢性胃炎和医源性应激关系密切,对慢性胃炎和FD在处理上应作为一种病去对症处理,不必过度强调抗Hp.医生在临床工作中,要注意规范言行,合理解释病情,避免医源性应激给患者带来心理创伤,减少医源性心理疾病的发生.

    Objective To study the related factors in the development of chronic gastritis to gastric cancer, and to explore effective preventive measures. Methods Ninety-two patients with chronic gastritis and gastric cancer in our hospital from November 2011 to November 2014 were selected as observation group. And 92 patients who were diag-nosed with only chronic gastritis by gastroscope and pathological examination during the same period were selected as control group. The influence factors in the development of chronic gastritis to gastric cancer were analyzed by single factor analysis and logistic regression analysis. Results The related factors included pickles, hot food, mildew foods, fried foods, smoking, drinking, breakfast, diet, daily salt intake, intermittent use of acid and antacid drugs, history of digestive disease (P<0.05). Taking the above factors into logistic multivariate regression analysis, the result showed that pickles, mildew food, fried food, irregular diet, a history of digestive disease were risk factors in the development of chronic gastritis to gastric cancer, and that continuous use of acid and antacid drugs were protection factors (P<0.05). Conclusion The development of chronic gastritis to gastritis cancer is mainly related to eating habits, history of diges-tive disease. Good diet can reduce the risk of cancer in patients with chronic gastritis.%目的:研究慢性胃炎发展为胃癌的影响因素,探讨有效的预防措施。方法选择2011年11月至2014年11月在我院接受治疗的慢性胃炎合并胃癌患者92例作为观察组。选取同期经胃镜和病理学检查确诊为慢性胃炎的患者92例作为对照组。用单因素分析和Logistic回归分析慢性胃炎发展为胃癌的影响因素。结果慢性胃炎发展为胃癌与腌菜、烫食、霉变食品、油炸食品饮酒、吸烟、早餐、饮食规律、每日摄盐量、间断使用抑酸和制酸药物、消化道病史等因素有关(P<0.05)。将上

    As a commensal or a pathogen, Helicobacter pylori can change the balance of a complex interaction that exists among gastric epithelial cells, microbes, and their environment. Therefore, unraveling this complex relationship of these mixtures can be expected to help prevent cancer as well as troublesome unmet medical needs of H. pylori infection. Though gastric carcinogenesis is a multi-step process, precancerous lesion can be reversible in the early phase of mucosal damage before reaching the stage of no return. However, biomarkers to predict rejuvenation of precancerous atrophic gastritis have not been identified yet and gastric cancer prevention is still regarded as an impregnable fortress. However, when we take the journey from H. pylori-associated gastritis to gastric cancer, it provides us with the clue for prevention since there are two main preventive strategies: eradication and anti-inflammation. The evidence supporting the former strategy is now ongoing in Japan through a nation-wide effort to eradicate H. pylori in patients with chronic gastritis, but suboptimal apprehension to increasing H. pylori resistance to antibiotics and patient non-compliance still exists. The latter strategy has been continued in the author'sresearch center under siTRP (short-term intervention to revert premalignant lesion) strategy. By focusing on the role of inflammation in the development of H. pylori-associated gastric carcinogenesis, this review is intended to explain the connection between inflammation and gastric cancer. Strategies on H. pylori eradication, removal of inflammation, and reverting preneoplastic lesion will also be introduced. In the end, we expect to be able to prevent gastric cancer by take a detour from the unpleasant journey, i.e. from H. pylori-associated gastritis to gastric cancer. PMID:26691187

    Helicobacter pylori causes chronic (type B) gastritis. The 'intestinal' form of gastric cancer arises against a background of chronic gastritis, and prospective epidemiological studies have shown that H pylori is a major risk factor for this. An increase in mucosal cell proliferation increases the likelihood of a neoplastic clone of epithelial cells emerging where there is chronic epithelial cell injury associated with H pylori gastritis.

    The aim of this paper was to determine the topographic distribution of gastritis lesions in pigs through an open source geographic information system (GIS) software analysis. The stomachs of 146 Italian heavy pigs were collected at slaughter and subjected to macroscopic pathological examination of the internal mucosa. A total of 623 lesions were either classified as hyperplastic or follicular (97%) with the remaining minority of lesions categorised as atrophic and simple. The hyperplastic gastritis lesions had an average surface of 77.8 cm2 and were mainly located in an oval shaped area of the fundus region of the stomach near the Curvatura ventriculi major. The follicular gastritis lesions had generally a smaller surface (40.3 cm2) and were concentrated in two distinct small areas of the pyloric region. The GIS analysis provided the opportunity to produce useful maps showing the distribution and characteristics of gastritis in pigs. PMID:27245806

    Full Text Available Abstract Background Mast cells reside within the connective tissue of a variety of tissues and all vascularized organs. Since 1996, few studies have been performed on mast cell density in gastrointestinal biopsies, mainly in adult age group. We recently studied mast cell density in pediatric age group on rather larger number of cases in a referral children hospital. Mast cell density was 12.6 ± 0.87 in 0.25 mm2 (range: 0-81 in our study. Since we frequently encounter cases with rather normal gastric biopsies with no H.pylori, which mainly complain of chronic abdominal pain, we gathered those cases with mast cell density more than 30/0.25 mm2. from 895 gastric biopsies and wanted to study their clinical and endoscopic findings and propose a new entity. Methods Between April 2005 and May 2008, 895 children (2, were chosen and a questionnaire was filled for each patient including clinical, endoscopic and pathologic findings. The statistical analysis was performed using SPSS, version 13 (SPSS Inc., Chicago, IL, USA. Results Over a 3 year period of study, of 895 selected children, 86 patients fulfilled the entrance criteria. The major complaint of patients was recurrent abdominal pain. The mean mast cell density was 45.59 ± 13.81 in 0.25 mm2 (range: 30-93. Among our cases, about 67.4% (n = 58 had 30 to 49, 23.3% (n = 20 had 50 to 69, 8.1% (n = 7 had 70 to 89 and 1.2% (n = 1 had 93 mast cells/0.25 mm2 in their specimens Discussion In 29% of our cases, neither endoscopic nor pathologic change was detected and only increase in mast cell number was reported and in others endoscopic and histopathological findings were negligible except increase in mast cells. In updated Sydney system (classification and grading of gastritis, no term is introduced which is in concordance with this group but we think that increased density of mast cells in these cases should not be overlooked and it may contribute to clinical manifestations in some way. We hope that

    Full Text Available Introduction: Multiple sampling from different sites of the stomach as well as the number of fragments of gastric mucosa available for histopathologic evaluation are important sources of variation when classifying and grading chronic gastritis. Objective: To estimate the sensitivity of the number of fragments of gastric mucosa necessary to establish the diagnosis of atrophic gastritis with intestinal metaplasia, gastric dysplasia and H. pylori infection. In addition, this study will attempt to assess the intra-observer variability in the classification of these premalignant gastric lesions. Methods: This is a 6 year-cohort study, wherein 1958 gastric endoscopic procedures performed by two gastroenterologists were reviewed. Five gastric biopsy samples were obtained from the antrum, body and lesser curvature during each procedure. One pathologist was in charge of reviewing the five histopathology samples for each subject and providing a definitive diagnosis which was used as the gold standard. Each gastric mucosa sample reviewed led to an individual diagnosis for that sample which was compared with the gold standard. Intra-observer variability was assessed in 127 individuals who correspond to a random sample of 20% of the total endoscopic procedures performed during the 72 month-follow-up. Results: The sensitivity of the diagnosis of intestinal metaplasia (IM and gastric dysplasia increased proportionally with the number of gastric mucosa samples reviewed. The lesser curvature of the stomach had the highest sensitivity for the diagnosis of IM and dysplasia, among all the stomach regions studied. Just one sample of gastric mucosa attained a sensitivity of 95.9% for the detection of H. pylori infection. The intra-observer agreement for the diagnosis of multifocal atrophic gastritis was 86.1% and the kappa value was 0.79 (95% CI 0.76-0.85. Alcohol-fixed biopsy specimens were inadequate to diagnose H. pylori infection and to assess dysplasia

    International Nuclear Information System (INIS)

    Within this decade it has been determined that primary gastritis in both children and adults is frequently associated with infection of the gastric mucosa with Campylobacter pylori. It is characterized by a chronic inflammatory process in which the mucosa of the gastric antrum is typically most severely involved. Other regions of the stomach may be involved and associated peptic ulcers of the stomach and duodenal bulb are frequent. A case of C. pylori gastritis is reported in which involvement of the gastric fundus and body produced severe rugal hypertrophy that resembled Menetrier's disease. (orig.)

    Full Text Available Introduction. Helicobacter pylori (H. pylori infection is known to be the must common cause of chronic gastritis having some endoscopic and pathologic characteristies as determinated by the Sydney System for Gastritis Classification. The aim of our case report was to point out the relationship between an endoscopic finding of nodular antritis and the presence of H. pylori infection and active chronic gastritis. Case report. Our patient underwent upper gastrointestinal endoscopy for dyspeptic complaints and was diagnosed as having nodular antritis, but also underwent urease test and hystopathologic examination of antral mucosa, to determine the presence and density of H. pylori infection and the presence and severity of gastritis. After a course of anti H. pylori treatment, dyspepsia improved and new biopsy specimens obtained two months and six months afterwards revealed no pathological findings. Conclusion. The case report supported the association of H. pylori infection of lymphoid follicles with nodular gastric mucosis.

    Because the presence or absence of H pylori infection has important implications for therapeutic decisions based on histological assessment, the reproducibility of Sydney system is important. The study was designed to test the reproducibility of features of Helicobacter pylori gastritis,using the updated Sydney classification.METHODS: Gastric biopsies of 40 randomly selected cases of Hpylori gastritis were scored semiquantitatively by three pathologists. Variables analysed included chronic inflammation,inflammatory activity, atrophy, intestinal metaplasia, H pylori,surface epithelial damage. Κ values below 0.5 represented poor, those between 0.5 and 0.75 good and values over 0.75excellent interobserver agreement.RESULTS: The best interobserver agreement (κ=0.62) was present for intestinal metaplasia. The agreement was the poorest for evaluating atrophy (κ=0.31).CONCLUSION: Although the results of this study were in accordance with some previous studies, an excellent agreement could not be reached for any features of H pylori gastritis. This low degree of concordance is assumed to be due to the personal evaluation differences in grading the features, the lack of standardized diagnostic criteria, and the ignorance to reach a consensus about the methods to be used in grading the features of H pylori gastritis before initiating the study.

    AIM: To investigate the clinicopathological factors underlying the ethnic differences of Helicobacter pylori gastritis and cancer.METHODS: We analyzed clinicopathological parameters of gastric biopsies having H pylori infection that were randomly selected from different ethnic populations including 147 Americans, 149 Japanese, and 181 Koreans.RESULTS: Males were predominant in Japanese and Korean populations (77.9 and 67.4% respectively) in comparison with Americans (48.3%) (P<0.001). H pylori gastritis in Koreans and Japanese was characterized by the predominant antral involvement. In the antrum,neutrophilic infiltration into the proliferative zone of pit, i,e.acute foveolitis, was more frequent in Koreans (82%) than in Japanese (71%) (P<0.05) and Americans (61%) (P<0.001).Interstitial neutrophilic infiltration, intestinal metaplasia and atrophy were also frequent in Koreans and Japanese. In the body, the prevalence of acute foveolitis was not significantly different among the populations while chronic interstitial inflammation and lymphoid follicles were more pronounced in the body of Americans than in the body of others (P<0.01).CONCLUSION: The male-, and antrum-predominant Hpylori gastritis in Koreans and Japanese is compatible with the pattern of sex and topographical distribution of gastric cancer incidence. Our data suggest that persistent acute foveolitis at the proliferative zone is a crucial step in the gastric carcinogenesis.

    Objective To evaluate the clinical manifestations, endoscopic features and the clinical pathological characteristics of H. heilmannii-associated gastritis, and to compare these variables with those of H. pylori-ussociated gastritis. Methods The clinical data, endoscopic findings and pathologic characteristics of 3107 patients, who underwent endoscopy from 2005 to 2007, were retrospectively analyzed. Results Twenty-five cases of H. heilmannii infection were identified, the infection rates of H. heilmannii and H. pylori were 0.80% (25/3107) and 4.12% (1060/3107) respectively. Three cases were mixed infections. Of 25 patients, 20 showed such gastroenterologic symptoms to a greater or less extent as abdominal distending pain,nausea and anorexia, and other 5 cases were asymptomatic. All 25 patients showed chronic gastritis by en-doscopy, including chronic superficial gastritis (7/25, 28% ), erosion ( 3/25, 12% ), chronic atrophic gastritis (4/25, 16%), bile reflux(1/25, 4%), ulcer (1/25, 4%), polyp (1/25, 4%) and duodenal bulbar inflammation (2/25, 8% ). In rapid urease test, 3 cases were hyper-positive, 3 cases positive, 7 ca-ses mild-positive and 12 cases negative. According to histological observation, H. heilmannii scattered or ac-cumulated within the gastric pits, glandular lumen or mucus. The organism was observed in parietal cells with cell damage in one case. Sporadic lymphatic and plasmic infiltration were found in all patients with H.heilmannii infection, infiltration of neutrophils (12/25), gland atrophy and intestinal metaplasia (4/25)and lymphoid follicles (6/25) were also observed. Compared with H. pylori-associated gastritis, H. heilman-nii-associated gastritis showed less inflammation, less helicobacter density, mononuclear cell infiltration and neutrophilic activity ( P < 0.05 ). Conclusion H. heilmanaii mainly induces chronic gastritis, which is less severe than H. pylori-associated gastritis.%目的 评估上消化道H.heilmannii感染的临床表现

    Background Almost half of the world's population suffer from the Helicobacter pylori (H. Pylori) infection, but only some individuals develop gastric diseases with clinical symptoms. One reason for the phenomenon may be the different pathogenicity of infected H. Pylori strains. The presence of cytotoxin-associated gene A (cagA) and expression of vacuolating cytotoxin activity encoded by vacuolating cytotoxin gene A (vacA) are considered the two major virulent markers of H. Pylori. The aim of this study was to detect dominant cagA/vacA genotypes and coinfection frequency of H. Pylori in patients with peptic ulceration (PU) or chronic gastritis (CG), and to determine correlations among different cagA/vacA genotypes, coinfection and severity of the diseases. Methods For each of 139 patients in Zhejiang Province who had been diagnosed as PU or CG based on clinical symptoms and gastroscopy, two gastric biopsy specimens (one from antrum and the other from corpus) for H. Pylori isolation were taken by two different disinfected biopsy forceps. One hundred and fifty-six H. Pylori strains were isolated from both the antrum and corpus biopsy specimens of 78 patients (36 PU and 42 CG). PCRs were performed to detect cagA genes, and signal (s) and middle (m) regions of vacA genes in the H. Pylori isolates. The amplified fragments of dominant vacA gene s and m subtypes from representative H. Pylori isolates were sequenced after TA cloning. Dominant cagA/vacA genotypes of the H. Pylori isolates, coinfection frequency and correlations among the different genotypes, coinfection and severity of the diseases were determined.Results Of the H. Pylori strains isolated from the antrum specimens, 96.2% were cagA gene positive, as were 97.4% of the H. Pylori strains isolated from the corpus specimens. Only one s region subtype (s1a) and four m region subtypes m1, m2, m1b and m1b-m2 of vacA gene were found. The proportions of vacA gene subtypes s1a/m1, s1a/m2, s1a/m1b and s1a/m1b-m2 in the

  11. Immunoglobulin gene repertoire diversification and selection in the stomach – from gastritis to gastric lymphomas

    Directory of Open Access Journals (Sweden)

    Miri eMichaeli

    2014-06-01

    Full Text Available Chronic gastritis is characterized by gastric mucosal inflammation due to autoimmune responses or infection, frequently with Helicobacter pylori. Gastritis with H. pylori background can cause gastric mucosa-associated lymphoid tissue lymphoma (MALT-L, which sometimes further transforms into diffuse large B cell lymphoma (DLBCL. However, gastric DLBCL can also be initiated de novo. The mechanisms underlying transformation into DLBCL are not completely understood. We analyzed immunoglobulin repertoires and clonal trees to investigate whether and how immunoglobulin gene repertoires, clonal diversification and selection in gastritis, gastric MALT-L and DLBCL differ from each other and from normal responses. The two gastritis types (positive or negative for H. pylori had similarly diverse repertoires. MALT-L dominant clones presented higher diversification and longer mutational histories compared with all other conditions. DLBCL dominant clones displayed lower clonal diversification, suggesting the transforming events are triggered by similar responses in different patients. These results are surprising, as we expected to find similarities between the dominant clones of gastritis and MALT-L and between those of MALT-L and DLBCL.

    Full Text Available Gastric lipase is one of the prepancreatic lipases found in some mammalian species and in humans. Our knowledge of the hormonal regulation of gastric lipase secretion in children and adolescents is still very limited. The aim of this study was to compare the activity of human gastric lipase (HGL in gastric juice in healthy adolescents and in patients with gastritis. The adolescents were allocated to three groups: the first including patients with Helicobacter pylori gastritis (HPG; n = 10, the second including patients with superficial gastritis caused by pathogens other than H. pylori (non-HPG; n = 14 and the control group including healthy adolescents (n = 14. Activity of HGL was measured in gastric juice collected during endoscopy. Plasma concentrations of cholecystokinin (CCK, glucagon-like peptide-1 (GLP-1 and glucose-dependent insulinotropic peptide (GIP were measured in all adolescents. Activity of HGL in the non-HPG group was significantly lower than in the HPG group (p < 0.005 and the control group (p < 0.005. Mean plasma GIP levels in the control group were lower than in the non-HPG group (p < 0.003 and the HPG group (p < 0.01. We conclude that the regulation of HGL secretion by GLP-1 and CCK is altered in patients with gastritis. Moreover, GIP is a potent controller of HGL activity, both in healthy subjects and in patients with gastritis.

  13. Epithelial cell proliferation in human fundic and antral mucosae. Influence of superselective vagotomy and relationship with gastritis

    International Nuclear Information System (INIS)

    Epithelial cell proliferation in the fundic and antral mucosae was studied in 19 duodenal ulcer patients, 11 patients having undergone fundic superselective vagotomy for duodenal ulcer, and 10 controls. This was achieved through in vitro incorporation of tritiated thymidine in mucosal biopsies and radioautography. Except for increased fundic mucosal height, duodenal ulcer patients did not differ from controls for all parameters studied. In vagotomized patients, as compared to the other two groups, the labeling index was significantly enhanced in the innervated antral mucosa where atrophic gastritis developed, but there was no change in the labeling index and no worsening of mucosal inflammation in the denervated fundic mucosa. The only abnormality in the latter was a striking expansion, towards the surface, of the proliferative area within the fundic pit. The labeling indices and the degree of gastritis in gastric mucosae are significantly correlated in control and duodenal ulcer patients. If findings in antral mucosa, after superselective vagotomy, seemed related to gastritis lesions, those in fundic mucosa were not and may indicate an alteration due to the vagotomy per se

    Full Text Available Helicobacter pylori (H. pylori, el patógeno más común del tracto gastrointestinal en seres humanos, es la causa más frecuente de gastritis crónica, está asociado etiológicamente con úlcera gastroduodenal y algunos cánceres gástricos. La creciente acumulación de información ha hecho necesario reevaluar los conceptos de gastritis, dolor abdominal y dispepsia en pediatría, por lo que el objetivo de esta revisión fue actualizar estos conceptos enfatizando la relación de estas entidades y discutir la evidencia disponible para promover una buena práctica clínica, al respecto. La asociación entre la infección por H. pylori y otras condiciones, como dolor abdominal recurrente y dispepsia no ulcerosa, no ha sido demostrada y es más bien especulativa. El H. pylori es considerado un patógeno, porque, entre otras características, cumple cada uno de los postulados de Koch como causante de gastritis crónica; en efecto, H. pylori juega un rol crítico y necesario en la patogénesis de la gastritis crónica activa. El papel de H. pylori como causa de úlcera péptica en adultos ha sido bien establecido. Aunque en niños las evidencias no son tan potentes, sí son altamente sugerentes. Aun cuando la mayoría de la población mundial está colonizada por H. pylori, solo una pequeña proporción tendrá manifestaciones clínicas producidas por la infección.

    Helicobacter pylori infection triggers chronic inflammation of the gastric mucosa that may progress to gastric cancer. The hypoxia-inducible factors (HIFs) are the central mediators of cellular adaptation to low oxygen levels (hypoxia), but they have emerged recently as major transcriptional regulators of immunity and inflammation. No studies have investigated whether H. pylori affects HIF signaling in immune cells and a potential role for HIF in H. pylori-mediated gastritis. HIF-1 and HIF-2 expression was examined in human H. pylori-positive gastritis biopsies. Subsequent experiments were performed in naive and polarized bone marrow-derived macrophages from wild-type (WT) and myeloid HIF-1α-null mice (HIF-1(Δmyel)). WT and HIF-1(Δmyel) mice were inoculated with H. pylori by oral gavage and sacrificed 6 mo postinfection. HIF-1 was specifically expressed in macrophages of human H. pylori-positive gastritis biopsies. Macrophage HIF-1 strongly contributed to the induction of proinflammatory genes (IL-6, IL-1β) and inducible NO synthase in response to H. pylori. HIF-2 expression and markers of M2 macrophage differentiation were decreased in response to H. pylori. HIF-1(Δmyel) mice inoculated with H. pylori for 6 mo presented with a similar bacterial colonization than WT mice but, surprisingly, a global increase of inflammation, leading to a worsening of the gastritis, measured by an increased epithelial cell proliferation. In conclusion, myeloid HIF-1 is protective in H. pylori-mediated gastritis, pointing to the complex counterbalancing roles of innate immune and inflammatory phenotypes in driving this pathology.

    Objective To examine the relationship between Helicobacter pylori-related gastritis and the development of lymphoid tissue hyperplasia in the antral mucosa and to pursue its evolution after eradication of H.pylori in the aged. Methods Gastric antral mucosa biopsy specimens for microscopic study were obtained from 101 chronic gastritis patients over 60 years old with H.pylori-positive in the period from 2000 to 2001, and meanwhile those from 124 H.pylori-positive chronic gastritis patients under the age of 60 served as controls. Four to six weeks after a course of anti-H.pylori therapy, biopsy specimens were again obtained. Lym-phoid follicles and aggregates were counted and other pathologic features were scored according to the updated Sydney System for classification of chronic gastritis. Results The prevalence and density of lymphoid follicles and aggregates were significantly lower in the aged as compared with those in the control group, being 36. 6%(37/101) and 0. 41 vs. 72. 5%(90/124) and 0. 81, respectively(P<0.0001). The prevalence and density of lymphoid follicles and aggregates correlated strongly with the activity and severity of gastric antral mucosal inflammation in both groups. Eradication of H.pylori resulted in a decrease in the prevalence and density of lymphoid follicles and aggregates in both groups, especially in the aged group. Conclusion The prevalence and density of lymphoid follicles and aggregates in gastric antral mucosal biopsies correlated closely with H.phlori infection in the aged, therefore, anti-H.pylori treatment would be of importance to the aged patients infected with H.pylori.

  4. Predictive value of radiographic findings in gastritis

    International Nuclear Information System (INIS)

    In a retrospective review of biphasic upper gastrointestinal (GI) tract examinations in 300 consecutive patients with abdominal pain, blood loss, nausea and vomiting, weight loss or dysphagia, the author evaluated the frequency of radiographic findings suggestive of gastritis. Forty-eight patients had undergone endoscopy within 1 week of upper GI tract examination. ''Best findings'' were defined by receiver operating characteristic wave analysis of individual findings, including aphthous lesions, serrated or nodular folds, marginal spiculation, and luminal constriction. Most false negative studies were in the fundus or proximal body; most false positive studies were in the antrum. They present a pictorial dictionary of findings and data for use of ''best findings'' to improve sensitivity and specificity in the diagnosis of gastritis

    2013-01-01

    Full Text Available Abstract Definition of the disease Malignant atrophic papulosis (MAP, described independently by Köhlmeier and Degos et al., is a rare, chronic, thrombo-obliterative vasculopathy characterized by papular skin lesions with central porcelain-white atrophy and surrounding teleangiectatic rim. Epidemiology Less than 200 cases have been described in the literature. The first manifestation of MAP usually occurs between the 20th and 50th year of life. Clinical description The cutaneous clinical picture is almost pathognomonic. The histology is not consistent but in most cases it shows a wedge-shaped connective tissue necrosis in the deep corium due to a thrombotic occlusion of the small arteries. In the systemic variant, manifestations mostly occur at the intestine and central nervous system. Etiology The etiopathogenesis of the disease remains unknown, a genetic predisposition may occur. Vasculitis, coagulopathy or primary dysfunction of the endothelial cells have been implicated. Diagnostic methods Diagnosis is only based on the characteristic skin lesions. Differrential diagnosis It depends on the clinical presentation of MAP, but systemic lupus erythematosus and other connective tissue diseases need to be considered. Management No effective treatment exists for the systemic manifestations, while compounds that facilitate blood perfusion have achieved a partial regression of the skin lesions in single cases. Prognosis An apparently idiopathic, monosymptomatic, cutaneous, benign variant and a progressive, visceral one with approx. 50% lethality within 2–3 years have been reported. Systemic manifestations can develop years after the occurrence of skin lesions leading to bowel perforation and peritonitis, thrombosis of the cerebral arteries or massive intracerebral hemorrhage, meningitis, encephalitis, radiculopathy, myelitis.

    Full Text Available Forty-two pigs in a herd of 117 displayed various clinical signs of progressive atrophic rhinitis. The main signs included sneezing, coughing, lachrymation, serous to muco-purulent nasal discharge, and nasal bleeding in 1 pig. Three pigs had lateral deviation of the snout, while 4 had brachygnathia superior with obvious deformation of the face. Four acutely affected weaner pigs appeared weak, while the 7 chronically-affected pigs appeared smaller than their apparently unaffected penmates of the same age. Treatment of the acutely affected pigs with long-acting oxytetracycline at 20 mg/kg body weight intra-muscularly, repeated once after 7 days, reduced the severity but did not clear the sneezing from all the pigs. Fifteen pigs were slaughtered 2 months after the clinical diagnosis was made. The carcasses of the chronically affected pigs were about 15 % lighter than those of the apparently normal pigs of the same age and from the same pen, which translated to a loss of 921.00 Kenya shillings per pig (US$13.7. Diagnosis of progressive atrophic rhinitis was confirmed by sectioning the snouts of randomly selected slaughtered pigs with obvious deformation of the snout. Sections were madeat the level of the 1st/2nd upper premolar tooth. Varying degrees of turbinate atrophy, from mild to complete, were noted. Histopathology of the turbinates revealed metaplasia of nasal epithelium and fibrosis in the lamina propria.

    2015-03-01

    Full Text Available Management of breast cancer includes systematic therapies including chemotherapy and endocrine therapy can lead to a variety of symptoms that can impair the quality of life of many breast cancer survivors. Atrophic vaginitis, caused by decreased levels of circulating estrogen to urinary and vaginal receptors, is commonly experienced by this group. Chemotherapy induced ovarian failure and endocrine therapies including aromatase inhibitors and selective estrogen receptor modulators can trigger the onset of atrophic vaginitis or exacerbate existing symptoms. Symptoms of atrophic vaginitis include vaginal dryness, dyspareunia, and irritation of genital skin, pruritus, burning, vaginal discharge, and soreness. The diagnosis of atrophic vaginitis is confirmed through patient-reported symptoms and gynecological examination of external structures, introitus, and vaginal mucosa. Lifestyle modifications can be helpful but are usually insufficient to significantly improve symptoms. Non-hormonal vaginal therapies may provide additional relief by increasing vaginal moisture and fluid. Systemic estrogen therapy is contraindicated in breast cancer survivors. Continued investigations of various treatments for atrophic vaginitis are necessary. Local estrogen-based therapies, DHEA, testosterone, and pH-balanced gels continue to be evaluated in ongoing studies. Definitive results are needed pertaining to the safety of topical estrogens in breast cancer survivors.

  12. X-ray diagnosis of acute gastritis

    International Nuclear Information System (INIS)

    Abnormal gastric wall configurations in 27 cases of cause-unknown acute gastritis were studied roentgenographically with reference to their causative origins. Studies were made on roentgenograms (abnormal gastric wall configurations), endoscopic findings and extension of lesions of the subjected cases. Gastric contour showed 'staying', 'thumbprinting', 'undulate configuration' and 'squarish undulation', while 'chimney-like' finding suggestive of poor gastric wall stretch was observed in the whole antral region as well. The widened angulus ventriculi and expanded pyloric ring (insufficient constriction) were also seen. In some cases the lesion extended over to the duodenum and, as in the cases of acute gastritis, duodenal wall 'staying', 'thumbprinting' and varied duodenal wall undulation were seen in addition to edema and morphological changes of the Kerkring's folds. The lesions in the studied patients mostly extended from an epicenter of the antrum upward to the gastric corpus and downward near to Vater's papilla in the descending part of the duodenum. The affected regions were clearly distinguishable. It has been known that above-described roentgenographical findings in our studied patients were similar in part to those known in experimental studies carried out on animals with ischemic digestive tract. This strongly suggests that some of our patients had developed the disease due to ischemic causes. There were some discrepancies between roentgenographical (abnormal gastric wall configuration) and endoscopic findings in some studied patients. It has been our belief that abnormal gastric wall configuration reflects lesions in the inner part of the wall and, accordingly, roentgenographical examinations, as well as endoscopy, should be performed for the purpose of making correct diagnosis. It is also to be emphasized that angiography should be carried out on patients with relapsing acute gastritis without any specific cause. (author)

  15. Clonally Expanding Thymocytes Having Lineage Capability in Gamma-Ray-Induced Mouse Atrophic Thymus

    International Nuclear Information System (INIS)

    Purpose: To characterize, in the setting of γ-ray-induced atrophic thymus, probable prelymphoma cells showing clonal growth and changes in signaling, including DNA damage checkpoint. Methods and Materials: A total of 111 and 45 mouse atrophic thymuses at 40 and 80 days, respectively, after γ-irradiation were analyzed with polymerase chain reaction for D-J rearrangements at the TCRβ locus, flow cytometry for cell cycle, and Western blotting for the activation of DNA damage checkpoints. Results: Limited D-J rearrangement patterns distinct from normal thymus were detected at high frequencies (43 of 111 for 40-day thymus and 21 of 45 for 80-day thymus). Those clonally expanded thymocytes mostly consisted of CD4+CD8+ double-positive cells, indicating the retention of lineage capability. They exhibited pausing at a late G1 phase of cell cycle progression but did not show the activation of DNA damage checkpoints such as γH2AX, Chk1/2, or p53. Of interest is that 17 of the 52 thymuses showing normal D-J rearrangement patterns at 40 days after irradiation showed allelic loss at the Bcl11b tumor suppressor locus, also indicating clonal expansion. Conclusion: The thymocytes of clonal growth detected resemble human chronic myeloid leukemia in possessing self-renewal and lineage capability, and therefore they can be a candidate of the lymphoma-initiating cells.

  17. X-ray diagnosis of erosive gastritis

    International Nuclear Information System (INIS)

    A series of 602 patients are studied according to a standard protocol including double contrast examination, taking films with dosed compression and complete filling (accordingly 3+3+1 radiographs). A barium suspension at concentration 200.0 BaSO4 in 100 ml water is used as a positive contrast medium, and effervescent powder or pills - as a negative contrast. Erosive gastritis is diagnosed in 48 patients (7.9%) of which 38 present complete erosions (79.2%), 6 (12.6%) - incomplete, and 4 (8.3%) - mixed erosions. In 35 cases (72.9%) erosions are differentiated in double-contrast films, while in 21 (43.8%) - in those with compression. The advantage of the double contrast technique consists in visualization of erosions of the body of the stomach and discovering of incomplete erosions. In 483 patients a comparative assessment is done of the X-ray and endoscopic findings. There are recorded 5 false-positive and 25 false-negative radiological results. The sensitivity of the X-ray study in terms of erosive gastritis amounts to 59.7%. 15 refs., 4 figs. (orig.)

    A 64-year-old female referred to our hospital because of severe anemia. Peripheral blood examination showed macrocytic anemia; red blood cell count was 1.49 x 10(6)/microliters, hemoglobin concentration was 5.6 g/dl, hematocrit was 16.1% and MCV was 108 fl. Serum VB 12 level was significantly low as 58 pg/ml. Upper gastrointestinal examination disclosed chronic atrophic gastritis. Anti-intrinsic factor and anti-parietal cell antibodies were detected in the serum and Schilling's test was positive. Thus a diagnosis of pernicious anemia was made. Though the serum free T 3 and free T 4 levels were in normal ranges, the elevated serum TSH and positive tests for anti-microsome and anti-thyroglobulin antibodies indicated that the patient had chronic thyroiditis. Then other endocrinological examinations were performed. Low level of urinary 17-OHCS and a hypo-reactive pattern of rapid ACTH test led to a diagnosis of latent adrenal insufficiency. This case could be categorized into polyglandular autoimmune syndrome. PMID:9391308

We report a case of a 41-year-old woman with gastrodeuodenal intussusception due to gastritis cystica polyposa that developed in an unoperated stomach. CT revealed gastroduodenal intussusception and a cystic and solid mass with fat density in the second portion of the duodenum. Surgery and a pathologic examination confirmed gastritis cystica polyposa.

    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. PMID:27092307

    Full Text Available Introduction: The patients with persistent forms of Helicobacter pylori (HP infection are refractory to eradication treatment. They receive unsuccessful therapies, experience frequent recurrences and re-infections. One of the main reasons for the development of persistent forms is an inadequate and insufficient treatment. The persistent forms of HP infection create conditions for the maintenance of activity and for the progression of the induced chronic gastritis. In this aspect these cases will be at a higher risk for the development of gastric cancer. The aim of this study is: to monitor and analyze the cases with persistent HP infection and to establish an approach for their management. Clinical material and methods: The study includes 12 patients (8 female and 4 male at a middle age of 63,7, with a persistent HP infection, who have been observed for a period of five years. Two methods for the detection of HP infection are used – one invasive and one non-invasive. Upper endoscopy with morphological examination was performed. Results: In 9/12 patients HP was unsuccessfully treated for three times, in 2 patients – four times, and in 1 patient – five times. In all patients the initial treatment consisted of a standard triple therapy (STT. In 5 of them STT was conducted twice, with the same regimen for a period of seven days. Two patients received three courses of STT. In four patients an antibiotic resistance was established by means of a cultured assessment. In three cases an HP resistance to Clarithromycine and Metronidazole was demonstrated. Significant gastro-duodenal pathology with atrophic gastritis, intestinal metaplasia, and hyperplastic polyposis was found in all patients. The persistent clinical symptoms had 9 patients. Conclusion: We believe that a devised and proposed step strategy which covers early detection of infection, reliable diagnosis, adequate and successful treatment, and dispensary monitoring, contributes to the

    Full Text Available Background: Atrophic facial scars are always a challenge to treat, especially the ones that are deep-seated and/or involve much of the face. Microneedling or dermaroller therapy is a new addition to the treatment armamentarium for such scars that offers a simple and reportedly effective management of these scars. Aims: The aim of the present study was to perform an objective evaluation of the efficacy of dermaroller treatment in atrophic facial scars of varying etiology. Materials and Methods: Thirty-seven patients of atrophic facial scarring were offered multiple sittings of microneedling (dermaroller treatment and their scars were evaluated and graded clinically and by serial photography at the start as well as at two months after the conclusion of the treatment protocol. Any change in the grading of scars after the end of treatment and follow-up period was noted down. The patients were also asked to evaluate the effectiveness of the treatment received on a 1-10 point scale. The efficacy of dermaroller treatment was thus assessed both subjectively by the patients as well as objectively by a single observer. Results: Overall 36 out of the total of 37 patients completed the treatment schedule and were evaluated for its efficacy. Out of these 36 patients, 34 achieved a reduction in the severity of their scarring by one or two grades. More than 80% of patients assessed their treatment as ′excellent′ on a 10-point scale. No significant adverse effects were noted in any patient. Conclusions: Microneedling therapy seems to be a simple and effective treatment option for the management of atrophic facial scars.

  15. Prospective study in the management of high-dose radioactive iodine therapy induced gastritis

    International Nuclear Information System (INIS)

    Full text: Gastritis is simply defined as inflammation of the gastric mucosa. In post-RAI patients, this is one of the most common complications that are encountered. Some patients may even require repetitive administration of high doses of radioactive iodine (I-131). Small doses of radiation (up to 1500 R) cause reversible mucosal damage, whereas higher radiation doses cause irreversible damage with atrophy and ischemic-related ulceration. Reversible changes consist of degenerative changes in epithelial cells and nonspecific chronic inflammatory infiltrate in the lamina propria. Higher amounts of radiation cause permanent mucosal damage, with atrophy of fundic glands, mucosal erosions, and capillary hemorrhage. Associated submucosal endarteritis results in mucosal ischemia and secondary ulcer development. Recurrent gastritis, if left untreated, may be a predisposing factor for gastric malignancy. Methods:A total of thirty post-RAI subjects were evaluated for signs and symptoms of gastritis and were divided into 3 groups which were given drugs for gastritis (H2-receptor antagonist, proton pump inhibitor, and sucralfate). Survey forms were distributed to evaluate the presence of nausea, vomiting, epigastric pain (graded according to severity of pain), and gastrointestinal bleeding. Results were tallied accordingly. Results and Discussion: In a total of 3 subjects who were given sucralfate, all of them did not experience any nausea and vomiting. One subject experienced mild epigastric discomfort and another subject was able to experience a non-specific symptom of abdominal bloatedness. (Note: Subjects are still for completion) In theory, radiation irritates the mucosa causing inflammation and mucosal damage which is further irritated by gastric acid secretion. The administration of H2-receptor blockers and proton pump inhibitors only inhibit gastric acid secretion while existing inflammation of mucosa due to high doses of radiation is left untreated. However

    Full Text Available RACIONAL: A aderência do Helicobacter pylori à mucosa gástrica humana é pré-requisito para sua colonização e o desenvolvimento da gastrite crônica. Os antígenos de grupos sangüíneos, presentes no muco gástrico, são descritos como prováveis receptores da bactéria neste epitélio. A expressão alterada destes antígenos está associada ao desenvolvimento do câncer gástrico. OBJETIVOS: Verificar a ocorrência do Helicobacter pylori e a distribuição da expressão dos antígenos ABH e Lewis correlacionada com as alterações histopatológicas de pacientes com gastrite crônica. PACIENTES E MÉTODOS: Analisaram-se 63 amostras de sangue, saliva e biopsias gástricas de pacientes com gastrite crônica através das técnicas dot-blot-ELISA, imunoperoxidase indireta e colorações do Gram modificado e hematoxilina-eosina. RESULTADOS: Não foram encontradas associações significativas entre a presença da bactéria e os fenótipos de grupos sangüíneos ABH, Lewis e Secretor. Na maioria dos pacientes, a expressão dos antígenos ABH e Lewis, estava restrita principalmente ao epitélio foveolar da mucosa gástrica, concordando com a expressão ao nível salivar. A expressão inapropriada desses antígenos ocorria sempre na infecção pelo Helicobacter pylori e/ou alterações pré-neoplásicas da mucosa gástrica. Em áreas com metaplasia intestinal foi observada a redução da reatividade para os antígenos H e Le b, e principalmente o aumento de Leª. CONCLUSÃO: Alterações no padrão de glicosilação destes antígenos refletem diferentes estágios de diferenciação celular e são marcadores potenciais na avaliação diagnóstica e prognóstica das patologias gástricas.BACKGROUND:The major cause for chronic gastritis in human is the infection by the Helicobacter pylori.

    Full Text Available Background: Bile gastritis (gastropathy is a kind of gastritis which is caused by reflux of bile contents through duodenum on stomach. It can occur spontaneously without any former gastric surgeries which affect sphincter of pylorus. The positive impact of some certain drugs such as prokinetic agents e.g. metoclopramide, Proton-pump inhibitors (PPIs, cholestyramine and sucralfate in treating bile gastritis has been confirmed. This study has been conducted in order to analyze the effect of ursodeoxycholic acid (UDCA, which is a harmless drug, on patients with the bile gastritis. Materials and Methods: In this clinical trial, all patients with dyspepsia who were qualified to undertake endoscopy were enrolled and then 60 patients with bile gastritis were selected for the study. The patients were divided into two groups; a group was treated by UDCA, omeprazole and sucralfate and another one was treated with placebo, omeprazole and sucralfate for two weeks. Finally, at the end of the third week of treatment patients were examined.Results: A total of sixty 19-70 year-old patients (Mean: 46 years old included in this study. At the end of the study, there was not found any meaningful difference between the two groups in terms of pain intensity, heartburn intensity, severity of bloating, vomiting and early satiety; however, each group independently showed improvement of the mentioned indices after termination of the treatment (p=0.0005.Conclusion: Adding UDCA to the standard treatment (sucralfate is not clinically effective in curing the bile gastritis.

    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.

    Full Text Available Helicobacter pylori are considered the most common human pathogen colonizing gastric mucosa. Gastritis with or without H. pylori infection is associated with increase in levels of homocysteine and high-sensitivity C-reactive protein (hs-CRP but a more pronounced increase is noted in gastritis with H. pylori infection. Increasing level of homocysteine, due to decreased absorption of vitamin B12 and folic acid, together with increased CRP levels in gastritis with H. pylori infection may be the earliest event in the process of atherosclerosis and plaque formation. Retrospective study conducted at tertiary care hospital in Mumbai by Department of Biochemistry in association with Department of Surgery. Eighty patients who underwent gastroscopy in view of gastritis were subjected to rapid urease test for diagnosis of H. pylori infection. Vitamin B12, folic acid, homocysteine and hs-CRP were analyzed using chemiluminescence immuno assay. Student’s t-test, Pearson’s correlation and linear regression used for statistical analysis. Patients with H. pylori gastritis had significantly lower levels of vitamin B12 (271.6±101.3 vs 390.6±176.7 pg/mL; P=0.0005, as well as higher levels of homocysteine (17.4±7.4 vs 13.8±7.8 mmol/L; P=0.037 and hs-CRP (2.5±2.9 vs 1.2±1.1 mg/L; P=0.017, than in patients without H. pylori gastritis. However, folic acid showed (8.9±3.2 vs 10.0±3.6 ng/mL; P=0.171 no significant difference. Elevated homocysteine and hs-CRP in H. pylori gastritis may independently induce endothelial dysfunction, leading to cardiovascular pathology.

  4. Detection of gastritis by single- and double-contrast radiography

    International Nuclear Information System (INIS)

    Sixty-eight patients with various types of gastritis, 23 patients with normal stomachs, and four patients with other gastric diseases were examined in a prospective study to assess the sensitivity and specificity of single-contrast (SC) and double-contrast (DC) upper gastrointestinal examinations in the evaluation of gastritis. All patients underwent endoscopy with biopsy followed first by DC and then by SC radiography. The respective sensitivities of SC and DC radiography were 58% and 72% for all examinations and 59% and 77% for adequate examinations only. The respective specificities were 59% and 55% based on all examinations. Useful radiographic features included polypoid defects and erosions detected by both methods, abnormal folds and flattened margins detected by the SC technique, and narrowed lumen and crenulated margins detected by the DC technique. In 93% of all cases, the correct diagnosis was based on two or more of these radiographic features. According to this study, the radiographic sensitivity in the detection of gastritis is reliable only in cases of moderate-to-severe disease and only when based on findings of the DC examination. Neither SC nor DC radiography should be used as the primary screening method for patients with suspected gastritis, and the radiographic diagnosis should be restricted to the terms ''erosive'' or ''nonerosive gastritis.''

  5. Paradigm Shift in the Management of the Atrophic Posterior Maxilla

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available When the posterior maxilla is atrophic, the reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome sinus floor elevation technique and without graft can be proposed for an efficient treatment of clinical cases with a maxillary residual bone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ≤4 mm. Indications of the lateral sinus floor elevation are limited to cases with a residual bone height ≤ 2 mm and fused corticals, uncompleted healing of the edentulous site, and absence of flat cortical bone crest or when the patient wishes to wear a removable prosthesis during the healing period. The presented case report illustrates osteotome sinus floor elevation with and without grafting and simultaneous implant placement in extreme conditions: atrophic maxilla, short implant placement, reduced healing time, and single crown rehabilitation. After 6 years, all placed implants were functional with an endosinus bone gain.

    Three children presented with acute protein losing enteropathy and were found to have acute gastritis associated with Campylobacter pylori infection. Recovery from protein losing enteropathy was accompanied by resolution of the gastritis and the disappearance of C pylori from the gastric mucosa. Their clinical course suggested that the C pylori had caused the gastritis and the protein losing enteropathy. The association between gastritis caused by C pylori and protein losing enteropathy in ch...

    Background/Aims: Helicobacter pylori gastritis is a risk factor for the development of gastric cancer. The results of several studies indicate that gastric adenomas, which are considered premalignant lesions, may also be associated with H pylori gastritis. However, it is not clear whether there are different patterns of gastritis in these patients compared with patients with gastric cancer or patients with H pylori gastritis alone. Therefore, this study was designed to investigate the pattern...

    2014-10-01

    Russell body esophago-gastro-duodenitis is an unusual form of chronic inflammation, with only 22 cases being reported in PubMed. However, the prevalence and clinical significance remain unknown. This report describes the clinico-pathological characteristics of nine cases of Russell body gastritis (RBG) and one case of Russell body duodentitis (RBD), with nonspecific endoscopic appearance. The Mott cells (plasma cells with Russell bodies) showed κ light chain restriction in eight gastritis cases and λ light chain restriction in the duodentitis case, and there were no histological features that suggested lymphoma. Thus, a diagnosis of monoclonal RBG/RBD was made. Helicobacter pylori infection was found in 55.6% of RBG cases and in the RBD case. And, the clinical follow-up evaluations were uneventful. This report is the first study to describe this benign disease entity with monoclonality on a large-scale basis. In addition, the monoclonality of Mott cells cannot be used as evidence of an existing neoplastic lesion, and taken together, these findings may indicate a reactive process. PMID:25001185

    AIM: To conduct a detailed histological study of gastritis in adult patients attending an endoscopy clinic at a Kenyan teaching and referral hospital.METHODS: Biopsy specimens from consecutive patients were examined and graded according to the Updated Sydney System for H pylori infection, chronic inflammation, neutrophil activity, glandular atrophy and intestinal metaplasia. Also documented were gastric tissue eosinophil counts and presence of lymphoid follicles.RESULTS: The rate of the graded variables, in the antrum and corpus respectively, were as follows:H pylori infection (91%, 86%), chronic inflammation (98%, 93%),neutrophil activity (91%, 86%), glandular atrophy (57%,15%) and intestinal metaplasia (11%, 2%). Lymphoid follicles were noted in 11% of cases. Duodenal and gastric ulcers were documented in 32% and 2% respectively.The mean eosinophil count was 5.9 ± 0.74 eosinophils/HPF and 9.58 ± 0.93 eosinophils/HPF in the corpus and antrum respectively. Significant association was found between the degree of H pylori colonisation with chronic inflammation, neutrophil activity and antral glandular atrophy. Biopsies from the antrum and corpus showed significant histopathological discordance for all the graded variables.H pylori negative cases were associated with recent antibiotic use.CONCLUSION: The study reaffirms that H pylori is the chief cause of gastritis in this environment. The majority of patients show a moderate to high degree of inflammation but a low degree of glandular atrophy and intestinal metaplasia. The study shows that interrelationships between the histological variables in this African population are similar to those found in other populations worldwide including non-African populations.

    2013-01-01

    Caveolin-1 (Cav1) is a scaffold protein and pathogen receptor in the mucosa of the gastrointestinal tract. Chronic infection of gastric epithelial cells by Helicobacter pylori (H. pylori) is a major risk factor for human gastric cancer (GC) where Cav1 is frequently down-regulated. However, the function of Cav1 in H. pylori infection and pathogenesis of GC remained unknown. We show here that Cav1-deficient mice, infected for 11 months with the CagA-delivery deficient H. pylori strain SS1, developed more severe gastritis and tissue damage, including loss of parietal cells and foveolar hyperplasia, and displayed lower colonisation of the gastric mucosa than wild-type B6129 littermates. Cav1-null mice showed enhanced infiltration of macrophages and B-cells and secretion of chemokines (RANTES) but had reduced levels of CD25+ regulatory T-cells. Cav1-deficient human GC cells (AGS), infected with the CagA-delivery proficient H. pylori strain G27, were more sensitive to CagA-related cytoskeletal stress morphologies (“humming bird”) compared to AGS cells stably transfected with Cav1 (AGS/Cav1). Infection of AGS/Cav1 cells triggered the recruitment of p120 RhoGTPase-activating protein/deleted in liver cancer-1 (p120RhoGAP/DLC1) to Cav1 and counteracted CagA-induced cytoskeletal rearrangements. In human GC cell lines (MKN45, N87) and mouse stomach tissue, H. pylori down-regulated endogenous expression of Cav1 independently of CagA. Mechanistically, H. pylori activated sterol-responsive element-binding protein-1 (SREBP1) to repress transcription of the human Cav1 gene from sterol-responsive elements (SREs) in the proximal Cav1 promoter. These data suggested a protective role of Cav1 against H. pylori-induced inflammation and tissue damage. We propose that H. pylori exploits down-regulation of Cav1 to subvert the host's immune response and to promote signalling of its virulence factors in host cells. PMID:23592983

  18. Biological markers in Helicobacter pylori-associated gastritis and carcinoma: the value of a scoring system

    International Nuclear Information System (INIS)

    Helicobacter pylori-associated gastritis has been linked to the pathogenesis of gastric adenocarcinoma (GA), especially when assciated with intestinal metaplasia (IM) and atypia/dysplasia (A/D). We examined p53 expression, ploidy and proliferative activity and assessed H.pylori infection in relationship to IM and A/Din case of gastritis not associated with GA and in cases of GA. We examined 53 gastric biopsies from patients with gastritis not associated with GA, including patients with IM and/or A/D (n=35) and with gastritis associated with IM and/or A/D (n=21). Thirty-six distal gastrectomy specimens from patients with GA constituted a third group of patients. A scoring system that encompassed the presence or absence of H.Pylori, degree of gastritis, IM and/or A/D, p53, MIB-1prolefarative index (MPI) and ploidy was estimated in the cases of gastritis and in cancer associated mucosa (CAM) and the adenocarcinoma from patients withGA. Patients with GA had a higher median age than those with gastritis without IM and more were males (ratio 2.2:1). H.pylori was detected in 75% (40/53) of gastritis specimen and in 55% (20/36) of GA cases. There was a statistically significant difference between the incidence of gastritis without IM and/or A/D and CAM (p=0.01). p53 expression was seen in 67% of the cases (14/21) of gastritis with IM and/or A/D and only in 5% (2 cases ) of gastritis without IM (p=0.0005). A statistically significant difference in MPI was seen between CAM and GA (p=0.01) and gastritis without IM and/or A/D and gastritis with IM(p=0.004). Cases of gastritis without IM and/or or A/D has a median score of 8 while cases of gastritis with IM and/or A/D had a median score of 12 (p=0.0003). CAM had a median score of 13, which was significantly different than gastritis without IM and/or A/D(p=0.0003) The presence of IM and/or A/D can be used in H.pylori -associated gastritis as as starting point to further investigate high risk lesions.

    2012-01-01

    Full Text Available Abstract Background Bile reflux is one of the primary factors involved in the pathogenesis of gastric mucosal lesions in patients with chronic gastritis; however, little is known about the exact histological features of bile reflux and its contributions to gastric mucosal lesions in this disease, especially in children with primary bile reflux gastritis (BRG. The aim of this study was to investigate the classic histological changes of the gastric mucosa in children with primary BRG. Methods The Bilitec 2000 was used for 24 h monitoring of gastric bile in 59 children with upper gastrointestinal symptoms. The histological characteristics of the gastric mucosa were examined and scored. Results Thirteen of the 59 patients had a helicobacter pylori infection and were excluded; therefore, 46 cases were included in this study. The positive rate of pathological duodenogastric reflux was significantly higher in patients with foveolar hyperplasia than those without foveolar hyperplasia; however, the rate was significantly lower in patients with vascular congestion than those without vascular congestion. The longest reflux time and the total percentage time of bile reflux were significantly lower in patients with vascular congestion than those without vascular congestion. A total of 9 types of histological changes were analyzed using a binary logistic regression. Foveolar hyperplasia and vascular congestion in the superficial layer became significant variables in the last step of the stepwise regression. Conclusions Foveolar hyperplasia was associated with the severity of bile reflux, suggesting that it is a histological feature of primary BRG in children, while vascular congestion may be a protective factor.

    2015-11-01

    We present a case of gastritis cystica polyposa (GCP) that developed early after laparoscopy-assisted distal gastrectomy with BillrothⅠreconstruction. GCP is a chronic inflammatory gastric mucosal lesion that emerges at an anastomotic site usually after a long post-gastrectomy period, which is mainly caused by constant chemical stimulation by duodenal juice. In addition, chronic mechanical stimulation caused by reflux or stasis of gastrointestinal contents may also trigger GCP. Surgeons should ensure a functional and physiologically patent anastomosis during surgery. Hypergastrinemia, caused by persistent Helicobacter pylori infection or continuing administration of proton pump inhibitors, may also contribute to the development of GCP, as GCP is a type of hyperplastic polyp. Therefore, appropriate postoperative follow-up, including pylorus eradication and avoidance of unnecessary administration of proton pump inhibitors, seems to be needed in order to prevent the development of GCP. In our case, many factors exhibited the multiplier effect, resulting in early development of GCP. As GCP also attracts much attention as a precancerous lesion, appropriate prevention and prompt treatment are required. PMID:26805252

The polypoid cystic mass did not show any enhancing solid portion on a computed tomography. The gastric lesion was conclusively confirmed as GCP through endoscopic submucosal dissection. We report a rare case of GCP that occurred in an unoperated stomach

    Full Text Available Purpose: We report a case of adult-onset foveomacular vitelliform dystrophy (AOFVD complicated with atrophic involution and subsequent choroidal neovascularization (CNV and treated with intravitreal ranibizumab. Design: Case Report Methods: A 71-year-old woman diagnosed with AOFVD experienced a progression of the vitelliform lesion to the atrophic stage in her left eye immediately after cataract surgery. Best corrected visual acuity (BCVA decreased from 0.5 to 0.16. Ten months later, the patient was referred with new worsening of her visual acuity (0.05 and metamorphopsia. The spectral-domain optical coherence tomography (SD-OCT confirmed the presence of type 2 CNV next to the atrophic area. The patient was treated with 2 monthly injections of ranibizumab. Results: SD-OCT images improved significantly and her BCVA increased to 0.20 associated with subjective improvement of metamorphopsia. Conclusion: Ranibizumab may be effective for CNV in patients with AOFVD.

    Likewise in rodents, after complete spinal cord injury (SCI) the lower motor neuron (LMN) denervated human muscle fibers lose completely the myofibrillar apparatus and the coil distribution of myonuclei that are relocated in groups (nuclear clumps) in the center of severely atrophic muscle fibers. Up to two years of LMN denervation the muscle fibers with nuclear clumps are very seldom, but in this cohort of patients the severely atrophic muscle fibers are frequent in muscle biopsies harvested three to six years after SCI. Indeed, the percentage increased to 27 ± 9% (pbehavior in long term denervated muscle fibers. PMID:27478559

  2. Russell Body Gastroenteritis: An Aberrant Manifestation of Chronic Inflammation in Gastrointestinal Mucosa

    Full Text Available First described in 1998, Russell body gastritis is a rare chronic inflammatory condition characterized by abundant intramucosal polyclonal plasma cells, which contain intracytoplasmic eosinophilic globules of immunoglobulins (Russell bodies that displace the nucleus, with an accompanying chronic inflammatory infiltrate. Russell bodies represent a cellular response to overstimulation of plasma cells, leading to the accumulation of abundant, nondegradable, condensed immunoglobulin in dilated rough endoplasmic reticulum cisternae. Russell body gastritis usually occurs in the gastric antrum, but two cases of Russell body duodenitis have been recently described. Herein, we report an unusual case of Barrett esophagus with prominent lymphoplasmacytic infiltration and Russell bodies, which expands the current spectrum of Russell body gastritis/duodenitis. Given the various anatomic locations in which Russell body gastritis may arise, we suggest that “Russell body gastroenteritis” may be a more appropriate designation for this uncommon reactive condition.

    An important complication during insertion of implants in atrophic mandibles is the fracture that can be induced by preparation of the cavity. We designed this study to identify which configuration of cavities in the interforaminal region was the least likely to fracture. An electromechanical testing machine was used to measure breaking loads of specifically-designed synthetic models of atrophic mandibles. The implant cavities correlated with the common clinical patterns. Intact atrophied synthetic mandibles broke at a mean (SD) load of 729.48 (59.94) N (control group). Models with four different configurations of cavities fractured as follows: two short, wide cavities (8 x 4.2mm) at a mean (SD) load of 569.17 (67.7) N; two long, thin cavities (15 x2.8mm) at a load of 563.40 (62.0) N; four short, wide cavities (8 x 4.2mm) at a load of 667.01 (71.89) N; and four long, thin cavities (15 x 2.8mm) at a load of 409.50 (43.61) N. Biomechanical findings showed that there was a greater risk of fracture of atrophic mandibular models in long, thin implant cavities with more preparation sites. Each cavity prepared for an implant increased the risk of fracture in an atrophic mandible. The risk of fracture is greatest with long, thin cavities. PMID:27068851

    Full Text Available BACKGROUND: Oral lichen planus (OLP is a chronic inflammatory disease that causes bilateral white striations, papules, or plaques on the buccal mucosa, tongue, and gingivae. Erythema, erosions, and blisters may or may not be present. Several empirical therapies have been used in the treatment of (OLP. OBJECTIVE: To evaluate the effect of low level laser therapy (LLLT versus topical steroids for the treatment of erosive-atrophic lichen planus. SUBJECTS AND METHODS: Twenty-four patients with erosive-atrophic (OLP were categorized into two groups. In the first group patients were treated with 970nm diode laser irradiation, while, in the second group patients used topical corticosteroids (0.1% triamcinolone acetonide orabase. The gender, medical history and pain score were recorded. The pain score was measured before and after treatment by visual analogue scale (VAS. RESULTS: Steroid-treated group (0.1% triamcinolone acetonide orabase show reduced pain score than laser group. CONCLUSION: Topical steroids are more effective than LLLT. LLLT may be used as an alternative treatment for symptomatic OLP when steroids are contraindicated.

    AIM: To assess the mechanisms of protective action by different mild irritants through maintenance of gastric mucosal integrity and modulation of mucosal nitric oxide (NO) in experimental gastritis rats.METHODS: Either 200 ml/L ethanol, 50 g/L NaCl or 0.3 mol/LHCl was pretreated to normal or 800 mL/L ethanol-induced acute gastritis Sprague-Dawley rats before a subsequent challenge with 500 mL/L ethanol. Both macroscopic lesion areas and histological damage scores were determined in the gastric mucosa of each group of animals. Besides,gastric mucosal activities of NO synthase isoforms and of superoxide dismutase, along with mucosal level of leukotriene (LT)C4 were measured.RESULTS: Macroscopic mucosal damages were protected by 200 mL/L ethanol and 50 g/L NaCl in gastritis rats.However, although 200 mL/L ethanol could protect the surface layers of mucosal cells in normal animals (protection attenuated by NG-nitro-L-arginine methyl ester), no cytoprotection against deeper histological damages was found in gastritis rats. Besides, inducible NO synthase activity was increased in the mucosa of gastritis animals and unaltered by mild irritants. Nevertheless, the elevation in mucosal LTC4 level following 500 mL/L ethanol administration and under gastritis condition was significantly reduced by pretreatment of all three mild irritants in both normal and gastritis animals.CONCLUSION: These findings suggest that the aggravated 500 mL/L ethanol-evoked mucosal damages under gastritis condition could be due to increased inducible NO and LTC4 production in the gastric mucosa. Only 200 mL/L ethanol is truly "cytoprotective" at the surface glandular level of nongastritis mucosa. Furthermore, the macroscopic protection of the three mild irritants involves reduction of LTC4 level in both normal and gastritis mucosa, implicating preservation of the vasculature.

    Full Text Available The aim of the study was to identify new mechanisms of MALT-lymphoma of the stomach in patients with chronic H. pylori-associated gastritis. The article shows that the lowest level of the expression of Ki-67 and the molecule Bcl-2 is observed in lymphoid follicles of gastric mucosa in patients with chronic non-atrophic H. pylori-associated gastritis. Expression of Ki-67 and Bcl-2 has consistently increased in patients with chronic atrophic H. pylori-associated gastritis, reaching maximum values in patients with MALT-lymphoma of the stomach, which allows us to consider this as an option in the tumor progression of H. pylori-associated gastritis. The data obtained are able to improve the forecasting of H. pylori-associated gastritis.

  8. Carbon-14 urea breath test for the diagnosis of Campylobacter pylori associated gastritis

    International Nuclear Information System (INIS)

    Urease in the human gastric mucosa is a marker for infection with Campylobacter pylori (CP), an organism suspected of causing chronic gastritis and peptic ulceration. To detect gastric urease, we examined 32 patients who were being evaluated for possible peptic ulcer disease. Fasting patients were given 10 microCi (370 kBq) of 14C-labeled urea. Breath samples were collected in hyamine at intervals between 1 and 30 min. The amount of 14C collected at these times was expressed as: body weight X (% of administered dose of 14C in sample)/(mmol of CO2 collected). The presence of C. pylori colonization was also determined by examination of multiple endoscopic gastric biopsy specimens. On average, patients who were proven to have C. pylori infection exhaled 20 times more labeled CO2 than patients who were not infected. The difference between infected patients and C. pylori negative control patients was highly significant at all time points between 2 and 30 min after ingestion of the radionuclide (p less than 0.0001). The noninvasive urea breath is less expensive than endoscopic biopsy of the stomach and more accurate than serology as a means of detecting Campylobacter pylori infection. Because the test detects actual viable CP organisms, it can be used to confirm eradication of the bacterium after antibacterial therapy

  9. X-ray examination of the microstructure of the gastric mucosa under induced hypotension in chromic gastritis

    International Nuclear Information System (INIS)

    The possibility of using artificial stomach hypotension to decrease the dynamic obscurity and a better examination of stomach mucosa microrelief in cases when X-ray exposures exceed 0.1 s, is shown. 75 patients with various forms of chronic gastritis both under normal conditions and in the case of stomach hypotension are investigated. The ''Diagnomax-M-125'' X-ray diagnostic device with the DR tube 125/30/50 kWt (and a small focus of 1.2x1.2 mm) is used. Optimum exposures during the roentgenography of stomach fields are increased up to 0.16 s. Under conditions of artificial stomach hypotension a clear image of microrelief is obtained 2 times more often, while the absence of the image of stomach field takes place 4 times more seldom than when using the conventional technique. In the case of stomach hypotension the picture of areola is less seldom unclear

    We report a case of radiation gastritis in consequence of radiotherapy for recurrent ovarian cancer. A 61-year-old woman received irradiation of a metastatic lesion of the second lumbar vertebra. Six months later she complained of fatigue and presented with severe anemia, and her diagnosis was hemorrhagic radiation gastritis. She was treated endoscopically, but that failed to control the bleeding, making it necessary to resect surgically. The incidence of radiation gastritis is very low because the stomach is rarely within the treated field, but it is of importance to be aware that the stomach is by no means more radioresistant than other organs.

    2009-01-01

    Full Text Available Background and objectives: Helicobacter pylori causes chronic gastritis, peptic ulceration, and is a risk factor for gastric cancer. More than half of the world`s population is infected with this pathogen, however the disease outcome varies. Among the virulence factors of H. pylori, specific adhesions to gastric epithelium may be an important step in the induction of active inflammation. H. pylori displays considerable genetic diversity attributed to genetic drift during long-term colonization. Heterogeneity of clinical-isolates has considerably impacted in understanding the role of each factor in infection outcome. However, genetic change may be more limited in the stomach of children in the short period after infection. This work evaluates differences in adherence potential of strains isolated from children with various chronic- inflammation status."nMaterials and Methods: A total of 157 children admitted to Medical Center of Tehran for upper gastrointestinal problems underwent endoscopy for H. pylori infection. Histological examination of their biopsies was performed after H& E and Giemsa staining. Gastritis and inflammation were graded according to the updated Sydney system. 70 culture-positive children, 20 were selected according to their histopathological status. Adherence of their H. pylori isolates to HEp- 2 cells was evaluated by viable count of bacteria associated with host cells in an optimized procedure developed in this study."nResults: Correlation was seen between inflammation severity score and efficiency of adhesion to HEp-2 cells. This correlation was not observed in the KB cell line as an epithelial cell-model."nConclusion: Specific interaction of H. pylori with host gastric epithelium may be associated with disease outcome

    AIM: To evaluate the histological features of gastric mucosa, including Helicobacter pylori infection in patients with early gastric cancer and endoscopically found superficial gastritis, gastric erosion, erosive gastritis,gastric ulcer.METHODS: The biopsy specimens were taken from the antrum, corpus and upper angulus of all the patients.Giemsa staining, improved toluidine-blue staining, and H pylori-specific antibody immune staining were performed as appropriate for the histological diagnosis of H pylori infection. Hematoxylin-eosin staining was used for the histological diagnosis of gastric mucosa inflammation, gastric glandular atrophy and intestinal metaplasia and scored into four grades according to the Updated Sydney System.RESULTS: The overall prevalence of H pylori infection in superficial gastritis was 28.7%, in erosive gastritis 57.7%,in gastric erosion 63.3%, in gastric ulcer 80.8%, in early gastric cancer 52.4%. There was significant difference (P<0.05), except for the difference between early gastric cancer and erosive gastritis. H pylori infection rate in antrum, corpus, angulus of patients with superficial gastritis was 25.9%, 26.2%, 25.2%, respectively; in patients with erosive gastritis 46.9%, 53.5%, 49.0%,respectively; in patients with gastric erosion 52.4%, 61.5%,52.4%, respectively; in patients with gastric ulcer 52.4%,61.5%, 52.4%, respectively; in patients with early gastric cancer 35.0%, 50.7%, 34.6%, respectively. No significant difference was found among the different site biopsies in superficial gastritis, but in the other diseases the detected rates were higher in corpus biopsy (P<0.05). The grades of mononuclear cell infiltration and polymorphonuclear cell infiltration, in early gastric cancer patients, were significantly higher than that in superficial gastritis patients, lower than that in gastric erosion and gastric ulcer patients (P<0.01);however, there was no significant difference compared with erosive gastritis.

    AIM: To detect the telomerase activity and c-Myc expression in gastric diseases and to examine the relation between these values and Helicobacter pylori (H pylori) as a risk factor for gastric cancer.METHODS: One hundred and seventy-one gastric samples were studied to detect telomerase activity using a telomerase polymerase chain reaction enzyme linked immunosorbent assay (PCR-ELTSA), and c-Myc expression using immunohistochemistry.RESULTS: The telomerase activity and c-Myc expression were higher in cancers (87.69% and 61.54%) than in noncancerous tissues. They were higher in chronic atrophic gastritis with severe intestinal metaplasia (52.38% and 47.62%) than in chronic atrophic gastritis with mild intestinal metaplasia (13.33% and 16.67%). Tn chronic atrophic gastritis with severe intestinal metaplasia, the telomerase activity and c-Myc expression were higher in cases with -H pylori infection (67.86% and 67.86%) than in those without infection (21.43%and 7.14%). c-Myc expression was higher in gastric cancer with H pylori infection (77.27%) than in that without infection (28.57%). The telomerase activity and c-Nyc expression were coordinately up-regulated in H pylori infected gastric cancer and chronic atrophic gastritis with severe intestinal metaplasia.CONCLUSION: H pylori infection may influence both telomerase activity and c-Myc expression in gastric diseases,especially in chronic atrophic gastritis.

    Full Text Available Introduction: Oral lichen planus (OLP is a common chronic mucocutaneous disease. Patients with atrophic and erosive types of OLP often have symptoms of soreness, and require proper treatment. The main treatment for OLP has been the administration of topical or systemic corticosteroids. The objective of this study was to compare the efficacy of adcortyl cream (triamcinolone acetonide in orabase with topical pimecrolimus cream for the treatment of erosive OLP.   Materials and Methods: Twenty-eight patients with OLP were enrolled in a single blind clinical trial and assigned to either a pimecrolimus 1% cream group or an adcortyl 0.1% cream group. The medication was applied every day for 2 months and patients were assessed every 2 weeks.   Results: The mean lesion size and mean pain and burning sensation scores did not differ between the pimecrolimus and adcortyl cream groups. The pimecrolimus cream was well tolerated. No clinical drug-related adverse events were observed.   Conclusion:  Topical pimecrolimus cream may be recommended as a safe and effective alternative therapy in the treatment of OLP. Pimecrolimus cream is as effective as adcortyl cream in managing the signs and symptoms of OLP.

    In our clinical experience, postprandial symptomatic hypoglycemic (PSH) patients with H. pylori gastritis showed a substantial improvement in their hypoglycemic symptoms after the eradication of H. pylori. Therefore, in this study we have investigated whether H. pylori gastritis may contribute to the occurrence of PSH. For this purpose, we have evaluated the following parameters in 12 PSH patients with H. pylori gastritis before and one month after the eradication therapy: (1) the number and severity of PSH attacks that occurred in a one-month period using a 30-day diary, (2) the total symptom score following a mixed meal using a visual analog scale questionnaire (VASQ), and (3) the glucose and insulin responses to the mixed meal. After the eradication of H. pylori, the serum insulin responses at 30 and 60 min decreased (P VASQ decreased significantly (P < 0.001 in all). These results suggest that H. pylori gastritis may contribute to the occurrence of PSH. PMID:10505722

    The aim of this study was to identify the species and determine the prevalence of gastric Helicobacter in the saliva of dogs with gastritis. The study was carried out on 30 dogs of different breeds, genders and ages, which were diagnosed with gastritis. The nested-PCR method was used to detect Helicobacter spp. in saliva. Helicobacter bacteria were found in the saliva samples of 23 (76.6%) dogs. Helicobacter heilmannii was the most commonly detected species of gastric Helicobacter spp. in canine saliva, and was found in 22 (73.3%) cases. The results indicate that gastric Helicobacter spp. occurs relatively frequently in dogs with gastritis. Moreover, the saliva of dogs with gastritis may be a source of Helicobacter spp. infection for humans and other animals. However, further studies are needed to confirm this finding as the PCR method does not distinguish active from inactive infections. PMID:27096797

    AIM: Lymphocytic gastritis is commonly ass ociated with Helicobacter pylori infection. The presence of glandular atrophy and foveolar hyperplasia in lymphocytic gastritis suggests abnormalities in cell proliferation and differentiation,forming a potential link with the suspected association with gastric cancer. Our aim was to compare epithelial cell proliferation and morphology in H pylori associated lymphocytic gastritis and H pylori gastritis without features of lymphocytic gastritis,and to evaluate the effect of H pylori treatment.METHODS: We studied 14 lymphocytic gastritis patients with H pylori infection. For controls, we selected 14 matched dyspeptic patients participating in another treatment trial whose H pylori infection had successfully been eradicated.Both groups were treated with a triple therapy and followed up with biopsies for 6-18 months (patients) or 3 months (controls). Blinded evaluation for histopathological features was carried out. To determine the cell proliferation index,the sections were labeled with Ki-67 antibody.RESULTS: Before treatment, lymphocytic gastritis was characterized by foveolar hyperplasia (P=0.001) and glandular atrophy in the body (P=0.008), and increased proliferation in both the body (P=0.001) and antrum (P=0.002). Proliferation correlated with foveolar hyperplasia and inflammation activity. After eradication therapy, the number of intraepithelial lymphocytes decreased in the body (P=0.004)and antrum (P=0.065), remaining higher than in controls (P<0.001). Simultaneously, the proliferation index decreased in the body from 0.38 to 0.15 (P=0.043), and in the antrum from 0.34 to 0.20 (P=0.069), the antral index still being higher in lymphocytic gastritis than in controls (P=0.010).Foveolar hyperplasia and glandular atrophy in the body improved (P=0.021), reaching the non-LG level.CONCLUSION: In lymphocytic gastritis, excessive epithelial cell proliferation is predominantly present in the body, where it associates with

    It′s still controversial whether certain macroscopic endoscopic features can be used to diagnose Helicobacter pylori (HP) related gastritis. The literature dealing with this subject is confusing, because of the lack of precise terminology, no large control trials, major discrepancies in interpretations of macroscopic changes and poor correlation of the macroscopic appearance and histological finding of gastritis. We conducted a prospective study of 208 dyspeptic patients, who underwe...

    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.

  10. Major motor atrophic patterns in the face and neck: CT evaluation

    International Nuclear Information System (INIS)

    Cranial nerve deficits from various pathologic processes of the head and neck may result in characteristic patterns of denervation muscular atrophy. Such atrophic patterns may be clues to the location and extent of the lesion, particularly when cranial nerves are involved early in the course of the disease process. Thirty-six patients with computed tomographic (CT) evidence of muscular atrophy secondary to pathologic conditions involving the motor division of cranial nerves were examined. Five characteristic denervation muscular atrophy patterns seen on CT scans were identified. Recognition of these atrophic patterns can prevent misinterpretation of their CT appearance and direct the CT examination to the course of the compromised cranial nerve from the brainstem to its peripheral innervation

    A 59-year-old man who had ulcerative proctitis for 18 years visited our hospital because of stomach pain. Proctitis had been in remission stage for five recent years by the mesalazine administration. Esophagogastroduodenoscopy (EGD) showed scattered patchy erosions at the corpus of the stomach. Anti-acid secretory agents was administrated, however, erosive change worsened in multiplicity and in area. Biopsied specimen of gastric mucosa showed specific findings resembling to cryptitis, crypt abcess and focally enhanced gastritis. H. pylori infection was negative by some examinations. Our patient had no history of taking non steroidal anti-inflammatory drugs (NSAIDs) so far. From the findings above, it was considered that gastric lesion was strongly related to the ulcerative proctitis. 5-aminosalicylic acid (750 mg, three times daily) ground to powder was administered with predonisolon (20 mg, once daily). Five month later, all the erosions disappeared completely on EGD and biopsied specimen revealed a reduction of inflammatory cells. The present case has a rare gastric lesion with patchy pattern (not diffuse pattern) which is strongly associated with ulcerative proctitis. PMID:19122423

    The discovery of Helicobacter pylori as the cause of gastritis and peptic ulcers ushered in the modern era of research into gastritis and into acid-peptic diseases and rekindled interest in the role of ascorbic acid in the pathophysiology and treatment of gastritis and peptic ulcer disease. Here, we review historic and modern studies on ascorbic acid and gastric diseases with an emphasis on H. pylori gastritis and its sequelae. The relationship of ascorbic acid and gastritis and peptic ulcer and its complications was extensively studied during the 1930s through the 1950s. Much of this extensive literature has been effectively "lost." Ascorbic acid deficiency was associated with all forms of gastritis (e.g., autoimmune, chemical, and infectious) due in varying degrees to insufficient intake, increased metabolic requirements, and destruction within the GI tract. Importantly, gastritis-associated abnormalities in gastric ascorbic acid metabolism are reversed by H. pylori-eradication and potentially worsened by proton pump inhibitor therapy. Diets rich in naturally occurring ascorbic acid are associated with protection of the gastric corpus from atrophy and a reduction in the incidence of gastric cancer possibly through the ability of ascorbic acid to reduce oxidative damage to the gastric mucosa by scavenging carcinogenic N-nitroso compounds and free radicals and attenuating the H. pylori-induced inflammatory cascade. Ascorbic acid supplementation was possibly associated with a decreased incidence of bleeding from peptic ulcer disease. Pharmacologic doses of ascorbic acid also may improve the effectiveness of H. pylori-eradication therapy. Occasionally, looking back can help plot the way forward. PMID:22543844

    Radiation-induced gastritis is an infrequent cause of gastrointestinal bleeding.It is a serious complication arising from radiation therapy,and the standard treatment method has not been established.The initial injury is characteristically acute inflammation of gastric mucosa.We presented a 46-year-old male patient with hemorrhagic gastritis induced by external radiotherapy for metastatic retroperitoneal lymph node of hepatocellular carcinoma.The endoscopic examination showed diffuse edematous hyperemicmucosa with telangiectasias in the whole muscosa of the stomach and duodenal bulb.Mlultiple hemorrhagic patches with active oozing were found over the antrum.Anti-secretary therapy was initiated for hemostasis,but melena still occurred off and on.Finally,he was successfully treated by prednisolone therapy.We therefore strongly argue in favor of perdnisolone therapy to effectively treat patients with radiation-induced hemorrhagic gastritis.

    Full Text Available STUDY BACKGROUND Post acne scars are always a challenge to treat, especially the ones which are deep seated. There are many treatment options like laser resurfacing, dermabrasion, microdermabrasion and non-ablative laser resurfacing but with considerable morbidity and interference with the daily activities of the patient in the post-treatment period. Microneedling or dermaroller therapy is one of the new treatment options in the management of acne scars with satisfactory improvement and no significant side effect. The aim of the present study is to perform an objective evaluation the efficacy of microneedling in the treatment of atrophic acne scars. MATERIALS AND METHODS Thirty patients of skin type III-V having atrophic facial acne scars presenting to our dermatology OPD. were received multiple sittings of microneedling (dermaroller treatment with an interval of 6 weeks between each session. Goodman & Baron’s acne scar grading system was used for assessment of their scars and was evaluated clinically by serial photography at the start as well as at two months after the conclusion of the treatment. Patients on anticoagulant therapy, of keloidal tendency, with bleeding disorders, vitiligo patients, pregnant and lactating mothers and patients with active acne lesions were excluded from the study. The duration of this study was for ten months-from January 2014 to October 2014. RESULTS Any change in the grading of scars after the end of treatment and follow-up period was noted down. The efficacy and improvement of dermaroller treatment was assessed by Goodman and Baron’s Global Acne Scarring System. Out of 30 patients, 26(80.64% patients achieved a reduction in the severity of their scarring by one or two grades. Quantitative assessment showed that 13.3% of patients had minimal, 16.6% had good and 70% showed very good improvement. Adverse effects were limited to transient pain, erythema and edema.

    Full Text Available Background: While laser resurfacing remains the most effective treatment option for atrophic acne scars, the high incidence of post-treatment adverse effects limits its use. Fractional laser photothermolysis attempts to overcome these limitations of laser resurfacing by creating microscopic zones of injury to the dermis with skip areas in between. Aim: The aim of the present study is to assess the efficacy and safety of fractional CO 2 laser resurfacing in atrophic facial acne scars. Materials and Methods: Sixty patients with moderate to severe atrophic facial acne scars were treated with 3-4 sessions of fractional CO 2 laser resurfacing at 6-week intervals. The therapeutic response to treatment was assessed at each follow up visit and then finally 6 months after the last laser session using a quartile grading scale. Response to treatment was labelled as ′excellent′ if there was >50% improvement in scar appearance and texture of skin on the grading scale while 25-50% response and <25% improvement were labelled as ′good′ and ′poor′ response, respectively. The overall satisfaction of the patients and any adverse reactions to the treatment were also noted. Results: Most of the patients showed a combination of different morphological types of acne scars. At the time of final assessment 6 months after the last laser session, an excellent response was observed in 26 patients (43.3% while 15 (25% and 19 patients (31.7% demonstrated a good and poor response respectively. Rolling and superficial boxcar scars responded the best while pitted scars responded the least to fractional laser monotherapy. The commonest reported adverse effect was transient erythema and crusting lasting for an average of 3-4 and 4-6 days, respectively while three patients developed post-inflammatory pigmentation lasting for 8-12 weeks. Conclusions: Fractional laser resurfacing as monotherapy is effective in treating acne scars especially rolling and superficial boxcar

    The Helicobacter pylori is associated with the development of different diseases. The clinical outcome of infection may be associated with the cagA bacterial genotype. The aim of this study was to determine the EPIYA patterns of strains isolated from patients with gastritis and gastric adenocarcinoma and correlate these patterns with the histopathological features. Gastric biopsy samples were selected from 384 patients infected with H. pylori, including 194 with chronic gastritis and 190 with gastric adenocarcinoma. The presence of the cagA gene and the EPIYA motif was determined by PCR. The cagA gene was more prevalent in patients with gastric cancer and was associated with a higher degree of inflammation, neutrophil activity, and development of intestinal metaplasia. The number of EPIYA-C repeats showed a significant association with an increased risk of gastric carcinoma (OR = 3.79, 95% CI = 1.92-7.46, and P = 0.002). A larger number of EPIYA-C motifs were also associated with intestinal metaplasia. In the present study, infection with H. pylori strains harboring more than one EPIYA-C motif in the cagA gene was associated with the development of intestinal metaplasia and gastric adenocarcinoma but not with neutrophil activity or degree of inflammation.

    Full Text Available Background: Helicobacter pylori (HP have recently emerged as a novel eliciting factor for chronic urticaria (CU. The possible association between HP and CU has enormous potential, as eradicating HP could cure CU. Aims and Objectives: We conducted a study to assess the prevalence of HP infection and effect of bacterium eradication on skin lesions in patients of chronic idiopathic urticaria (CIU. Settings and Design: Four hundred sixty patients of CU attending the allergy clinic, SMS hospital, Jaipur during the period February 6, 2004, to February 6, 2006, were screened for possible eliciting factors. Patients with CIU were enrolled and others were excluded. Materials and Methods: Sixty-eight patients of CIU and similar number of age and sex matched controls, attending the allergy clinic, SMS Hospital, Jaipur were enrolled in the study. All patients underwent endoscopy with antral biopsy for urease and histopathology to identify HP-associated gastritis. Infected patients were given HP eradication therapy. Eradication of bacterium was confirmed by fecal antigen assay. Subjective response to treatment was judged using chronic urticaria quality-of-life questionnaire (CU-Q 2 oL while objective response to treatment was judged by need for ′rescue medication′ (antihistaminics. Statistical Analysis: Data were analyzed using Chi square and paired′t′ test for their level of significance. Results: HP associated gastritis was present in 48 (70.58% patients, out of which 39 (81.25% patients responded to eradication therapy. Ten (50.00% patients without HP associated gastritis showed response to symptomatic therapy. Overall 49 (72.05% patients responded and 19 (27.94% showed no response. The value of χ2 was 28.571 (P = 0.003, which showed significant association between presence of HP and response to eradication regimen. Conclusion: The response of HP eradication therapy in infected patients of CIU is significant. HP should be included in diagnostic

    Cutaneous leishmaniasis is an endemic disease in Iran. Unfortunately, it can lead to unsightly atrophic scars with limited treatment options. Fractional CO2 laser is accepted for treatment of atrophic acne scars and recently has been used to treat cutaneous leishmaniasis, so we planned to use fractional CO2 laser on leishmaniasis scar. We conducted this study on 60 leishmaniasis scars on the face of 40 patients. The lesions were treated by a fractional CO2 laser with beam size of 120 μm, with energy of 50-90 mJ, and 50-100 spots/cm(2) density with two passes in three monthly sessions. Evaluation was done in the first and second months after the first treatment and 3 and 6 months after the last treatment. Digital photography was performed at each visit. Assessment of improvement rate by patient and physician was rated separately as follows: no improvement (0 %), mild (leishmaniasis scar. No significant adverse effects were noted. PMID:26984344

    2016-01-01

    PURPOSE The aim of this study was to investigate the stress distribution of 2-short implants (2SIs) installed in a severely atrophic maxillary molar site. MATERIALS AND METHODS Three different diameters of internal connection implants were modeled: narrow platform (NP), regular platform (RP), and wide platform (WP). The maxillary first molars were restored with one implant or two short implants. Three 2SI models (NP-oblique, NP-vertical, and NP-horizontal) and four single implant models (RP and WP in a centered or cantilevered position) were used. Axial and oblique loadings were applied on the occlusal surface of the crown. The von Mises stress values were measured at the bone-implant, peri-implant bone, and implant/abutment complex. RESULTS The highest stress distribution at the bone-implant interface and the peri-implant bone was noticed in the RP group, and the lowest stress distribution was observed in the 2SI groups. Cantilevered position showed unfavorable stress distribution with axial loading. 2SI types did not affect the stress distribution in oblique loading. The number and installation positions of the implant, rather than the bone level, influenced the stress distribution of 2SIs. The implant/abutment complex of WP presented the highest stress concentration while that of 2SIs showed the lowest stress concentration. CONCLUSION 2SIs may be useful for achieving stable stress distribution on the surrounding bone and implant-abutment complex in the atrophic posterior maxilla.

    Full Text Available Curcuma aromatica is an herbal medicine and traditionally used for the treatment of various diseases in Asia. We investigated the effects of C. aromatica water extract (CAW in the stomach of rats with ethanol-induced gastritis. Gastritis was induced in rats by intragastric administration of 5 mL/kg body weight of absolute ethanol. The CAW groups were given 250 or 500 mg of extract/kg 2 h before administration of ethanol, respectively. To determine the antioxidant effects of CAW, we determined the level of lipid peroxidation, the level of reduced glutathione (GSH, the activities of catalase, degree of inflammation, and mucus production in the stomach. CAW reduced ethanol-induced inflammation and loss of epithelial cells and increased the mucus production in the stomach. CAW reduced the increase in lipid peroxidation associated with ethanol-induced gastritis (250 and 500 mg/kg, p<0.01, resp. and increased mucosal GSH content (500 mg/kg, p<0.01 and the activity of catalase (250 and 500 mg/kg, p<0.01, resp.. CAW increased the production of prostaglandin E2. These findings suggest that CAW protects against ethanol-induced gastric mucosa injury by increasing antioxidant status. We suggest that CAW could be developed for the treatment of gastritis induced by alcohol.

    Only a few cases of contact allergic gastritis in patients with nickel allergy have been reported in the literature. We report a case of probable contact-allergic gastritis in a 46-year-old woman. Clinical examination revealed lichenoid mucosal lesions of the gums adjacent to a bridge and crowns that had been implanted several weeks previously. Since implantation, the patient suffered from gastrointestinal complaints including stomach pain. Gastroscopy and histological investigation of stomach biopsies showed eosinophilic gastritis. Patch testing done under the diagnosis of contact allergic stomatitis showed positive reactions to gold sodium thiosulphate, manganese (II) chloride, nickel (II) sulphate, palladium chloride, vanadium (III) chloride, zirconium (IV) chloride, and fragrances. The crowns and the bridge contained gold, palladium, and zirconium, hence they were replaced by titan-based dentition. Shortly after replacing the artificial dentition, all gastrointestinal symptoms resolved spontaneously without further treatment. Delayed-type allergy to components in the artificial dentition seem to have caused the gastritis. PMID:26909810

    AIM: To compare the reliability of gastritis staging systems in ranking gastritis-associated cancer risk in a large series of consecutive patients.METHODS: Gastric mucosal atrophy is the precancerous condition in which intestinal-type gastric cancer (GC) most frequently develops. The operative link for gastritis assessment (OLGA) staging system ranks the GC risk according to both the topography and the severity of gastric atrophy (as assessed histologically on the basis of the Sydney protocol for gastric mucosal biopsy). Both cross-sectional and long-term follow-up trials have consistently associated OLGA stages Ⅲ-Ⅳ with a higher risk of GC. A recently-proposed modification of the OLGA staging system (OLGIM) basically incorporates the OLGA frame, but replaces the atrophy score with an assessment of intestinal metaplasia (IM) alone. A series of 4552 consecutive biopsy sets (2007-2009) was retrieved and reassessed according to both the OLGA and the OLGIM staging systems. A set of at least 5 biopsy samples was available for all the cases considered.RESULTS: In 4460 of 4552 cases (98.0%), both the high-risk stages (Ⅲ + Ⅳ) and the low-risk stages (0 +Ⅰ + Ⅱ) were assessed applying the OLGA and OLGIM criteria. Among the 243 OLGA high-risk stages, 14 (5.8%) were down-staged to a low risk using OLGIM. The 67 (1.5%) incidentally-found neoplastic lesions (intraepithelial or invasive) were consistently associated with high-risk stages, as assessed by both OLGA and OLGIM (P < 0.001 for both). Two of 34 intestinal-type GCs coexisting with a high-risk OLGA stage (stage Ⅲ) were associated with a low-risk OLGIM stage (stage Ⅱ).CONCLUSION: Gastritis staging systems (both OLGA and OLGIM) convey prognostically important information on the gastritis-associated cancer risk. Because of its clinical impact, the stage of gastritis should be included as a conclusive message in the gastritis histology report. Since it focuses on IM alone, OLGIM staging is less sensitive than

    OBJECTIVE To analyze positive rates of the specific proteins CagA, VacA, UreA and UreB of Helicobacter pylori (Hp) in people in Xinin city Qinghai Province, a district with a high prevalence of gastric carcinoma, and to examine the relationship among the incidence, gross diagnosis and pathologic diagnosis. METHODS The gastric tissue biopsy specimens taken under endoscopy were examined by CLO,WS and Western Blot to judge the condition of the Hp infection. The positive rates of Hp CagA,VacA,UreA and UreB that had infected patients were evaluated. RESULTS The positive rate of UreA was markedly lower in chronic superficial gastritis (CSG) than in duodenal ulcer (DU) and compound ulcer, and also lower than in chronic atrophic gastritis(CAG), gastric ulcer(GU) and gastric cancinoma. However the positive rate of UreB was notably lower in duodenal ulcer and gastric ulcer than in chronic superficial gastritis and atrophic gastritis. The rates of UreB found in intestinal epithelial metaplasia, atrophic gastritis and gastric carcinoma were notably lower than in other diseases, however, it was markedly increased in chronic superficial gastritis, No differences were found among CagA and VacA of specimens with different endoscopic diagnosis or pathologic diagnosis. CONCLUSIONS The UreA in Hp may be relevant to the pathogenic mechanism of severe gastric diseases. However, UreB may have some protective effect on severe gastric diseases.

    The high incidence of gastric cancer in Japan initially resulted in establishment of a country-wide gastric cancer screening program to detect early and treatable cancers. In 2013 countrywide Helicobacter pylori (H. pylori) eradication was approved coupled with endoscopy to assess for the presence of chronic gastritis. Current data support the notion that cure of the infection in those with non-atrophic gastritis will prevent development of gastric cancer. However, while progression to more severe damage is halted in those who have already developed, atrophic gastritis/gastric atrophy remain at risk for subsequent development of gastric cancer. That risk is directly related to the extent and severity of atrophic gastritis. Methods to stratify cancer risk include those based on endoscopic assessment of the atrophic border, histologic grading, and non-invasive methods based on serologic testing of pepsinogen levels. Continued surveillance is required because those with atrophic gastritis/gastric atrophy retain considerable gastric cancer risk even after H. pylori eradication. Those who have already experienced a resectable early gastric cancer are among those at highest risk as metachronous lesions are frequent even after H. pylori eradication. We review the role of H. pylori and effect of H. pylori eradication indicating the incidence and the predictive factors on development of metachronous cancer after endoscopic therapy of early gastric cancer. Studies to refine risk markers to stratify for risk, surveillance methods, intervals, and duration after successful H. pylori eradication, and whether adjuvant therapy would change risk are needed.

    Collagenous gastritis (CG) is a rare disorder characterized by the thick collagenous subepithelial bands associated with mucosal inflammation. There have been approximately fifty reports in the literature since it was first described in 1989. According to previous reports, CG is heterogeneous and classified into two groups-(1) cases limited to the gastric mucosa in children or young adults, and (2) CG associated with collagenous colitis in elderly adults presenting with chronic watery diarrhea. In Japan, only nine previous cases were reported, and all of them were young adults. We report a case of CG with collagenous duodenitis in a 22-year-old female. She had repeated upper gastrointestinal bleeding from a Dieulafoy lesion of the fornix, but had no symptoms of malabsorption or diarrhea. Endoscopic findings revealed striking nodularity with a smooth islet-shaped normal area in the antrum and the body. The pathological findings of nodular mucosa showed the deposition of collagen bands just under the mucoepithelial lesion. In addition, she had collagenous duodenitis in part of the bulbs, and a colonoscopy showed no abnormalities. We provide a literature review of CG and collagenous gastroduodenitis without colonic involvement. PMID:26184019

    Helicobacter pylori is the major triggering factor for gastric carcinoma, but only a small proportion of infected patients develop this disease. Differences in virulence observed among H. pylori strains, namely in the vacuolating cytotoxin vacA gene, may contribute to this discrepancy. Infection with vacA s1, i1 and m1 strains increases the risk for progression of gastric premalignant lesions and for gastric carcinoma. However, in East Asian countries most of the H. pylori strains are vacA s1, regardless of the patients' clinical status, and the significance of the vacA i1 and m1 genotypes for gastric carcinoma in this geographic area remains to be fully elucidated. The aim of the present study was to investigate this relationship in 290 patients from Macau, China. Using very sensitive and accurate genotyping methods, we detected infection with vacA i1 and with vacA m1 strains in, respectively, 85.2% and 52.6% of the patients that were infected with single genotypes. The prevalence of cagA-positive strains was 87.5%. No significant associations were observed between vacA genotypes or cagA and gastric carcinoma. It is worth noting that 37.5% of the infected patients had coexistence of H. pylori strains with different vacA genotypes. Additional studies directed to other H. pylori virulence factors should be performed to identify high risk patients in East Asia. PMID:27164143

    Chronic pain in the orofacial region has always been a vexing problem for dentists to diagnose and treat effectively. For trigeminal neuropathic pain, there are 3 medications (gabapentinoids, tricyclic antidepressants, and serotonin-norepinephrine reuptake inhibitors) to use plus topical anesthetics that have therapeutic efficacy. For chronic daily headaches (often migraine in origin), 3 prophylactic medications have reasonable therapeutic efficacy (β-blockers, tricyclic antidepressants, and antiepileptic drugs). The 3 Food and Drug Administration-approved drugs for fibromyalgia (pregabalin, duloxetine, and milnacipran) are not robust, with poor efficacy. For osteroarthritis, nonsteroidal anti-inflammatory drugs have therapeutic efficacy and when gastritis contraindicates them, corticosteriod injections are helpful. PMID:27475515

    Full Text Available Objective: Mesenchymal stem cells (MSCs exist in the site of atrophic non-union fracture. The aim of this study was to evaluate the osteogenic potency of MSCs in order to have a better understanding of the unclear pathophysiology of atrophic non-union fracture Methods: This is an in vitro experimental study. Sample was obtained from the non-union site of a patient with a 6-years-history of atrophic non-union fracture of right femur. The MSCs was isolated from the fracture site and was cultured in the growth medium. Confirmation of the MSCs was performed and then osteogenic differentiation was performed in mono-layered MSC grown in both home-made and commercial osteogenic media. To evaluate the osteogenic differentiation, we performed Alizarin red staining and colorimetric assay for alkaline phosphatase (ALP. Results: From Alizarin red staining, most cells in the osteoblast medium were stained red by the staining. The result of colorimetric assessment of ALP shows that peak concentration was reached after 4 minutes in osteogenic group and control group. Conclusion: The presence of ALP activity and positive Alizarin red staining in our study showed that MSCs stem cells obtained from site of atrophic non-union is capable to be differentiated into osteogenic cells. .

    Full Text Available Ocular defects may cause several ocular and orbital disorders, which require surgical intervention. These defects are psychologically disturbing for the patients, and therefore, they require immediate management and rehabilitation by a team of specialist. Ocular prosthesis may be either readymade (stock or custom made. Fabrication of a custom ocular prosthesis allows for a range of variations during construction. The iris can also be custom made by ocular painting or by digital photography. The optimum cosmetic and functional results of a custom-made prosthesis enhance the patient′s rehabilitation to a normal life style. This paper elaborates the technique for fabrication of a custom-made ocular prosthesis for an atrophic eye socket utilizing digital photography.

    Full Text Available Long bone and in particular tibia fractures frequently fail to heal. A disturbed revascularisation is supposed to be a major cause for impaired bone healing or the development of non-unions. We aim to establish an animal model, which reliably mimics the clinical situation. Human microvascular endothelial cells (HMEC-1 and primary human osteoblast like cells (POBs were cultured with different angiogenesis-inhibitors (Fumagillin, SU5416, Artesunate and 3,5,4’-Trimethoxystilbene released out of poly(D,L-Lactide (PDLLA coated k-wires and cell activity was determined. Discs containing PDLLA or PDLLA + Fumagillin/Artesunate were placed at the chorionallantoic membrane of hen eggs and the effect on vessel formation and egg vitality was observed. Tibia osteotomy was performed in rats and stabilised with K-wires coated with PDLLA + Fumagillin or with PDLLA only (control group. The healing was compared at different time points to the PDLLA control. Fumagillin and Artesunate inhibited the activity of HMEC-1 with minor effect on POBs. Artesunate caused embryonic death, whereas Fumagillin had no effects on egg vitality, but reduced the blood vessels. In the animal study all rats showed an impaired healing with reduced biomechanical stability. The Fumagillin treated tibiae had a significantly decreased callus size at day 42 and 84, less blood vessels in the early callus, a reduced histological callus size at day 10, 28 and 84, as well as an altered callus composition. This study presents a less vascularised, atrophic, tibia non-union and can be used in further investigations to analyse the pathology of atrophic non-union and to test new interventions.

  3. In vivo 31P-NMR studies on the energy metabolism of atrophic muscles in rate

    International Nuclear Information System (INIS)

    Using P-31 NMR spectra, energy metabolism in the rat calf muscle was examined. The body weight in the atrophy and control groups did not differ significantly. Both the wet weight and dry weight of the calf muscle were significantly lower in the atrophy group than the control group. The muscle weight relative to the body weight was significantly lower in the atrophy group as well than the control group. There was no significant difference in the P-31 NMR spectral pattern before tourniquet ischemia between the atrophy and control groups. Rapid decrease in phosphocreatine (PCr) and rapid increase in inorganic phosphate (Pi) were observed in both groups immediately after application of the tourniquet; however, the rates of these changes were slightly greater and the PCr/Pi ratio in the peak values was significantly smaller in the atrophy group than the control group. The pH value before the ischemia was 7.15 ± 0.02 for the control group and 7.16 ± 0.02 for the atrophy group, with no significant difference between the groups. During ischemia, the pH value decreased progressively in the two groups; however, it became significantly decreased in the atrophy group from 10 to 60 min after application of tourniquet. The decrease in pH became gradual 60 min later. Since the decrease in pH was more rapid in the atrophic muscle than the intact muscle, this buffering capacity seems to be reduced in the atrophic muscle. (N.K.)

    Objectives To explore the therapeutic potential of combining bone marrow-derived mesenchymal stem cells (BM-MSCs) and hydroxyapatite (HA) granules to treat nonunion of the long bone. Methods Ten patients with an atrophic nonunion of a long bone fracture were selectively divided into two groups. Five subjects in the treatment group were treated with the combination of 15 million autologous BM-MSCs, 5g/cm3 (HA) granules and internal fixation. Control subjects were treated with iliac crest autograft, 5g/cm3 HA granules and internal fixation. The outcomes measured were post-operative pain (visual analogue scale), level of functionality (LEFS and DASH), and radiograph assessment. Results Post-operative pain evaluation showed no significant differences between the two groups. The treatment group demonstrated faster initial radiographic and functional improvements. Statistically significant differences in functional scores were present during the first (p = 0.002), second (p = 0.005) and third (p = 0.01) month. Both groups achieved similar outcomes by the end of one-year follow-up. No immunologic or neoplastic side effects were reported. Conclusions All cases of nonunion of a long bone presented in this study were successfully treated using autologous BM-MSCs. The combination of autologous BM-MSCs and HA granules is a safe method for treating nonunion. Patients treated with BM-MSCs had faster initial radiographic and functional improvements. By the end of 12 months, both groups had similar outcomes. Cite this article: H.D. Ismail, P. Phedy, E. Kholinne, Y. P. Djaja, Y. Kusnadi, M. Merlina, N. D. Yulisa.

    Full Text Available Background: Atrophic vaginitis is a disease, which affects up to 50% of postmenopausal women. This study compared the effectiveness and user-friendliness of Vagifem (an estradiol vaginal tablet and vaginal estrogen cream in the treatment of atrophic vaginitis. Materials and Methods: One hundred and sixty postmenopausal women with symptoms of atrophic vaginitis were randomly divided into two groups of treatment with Vagifem or with vaginal estrogen cream for 12 weeks. Patients used the medication daily for the first 2 weeks of the study, and twice weekly. Severity of vaginal atrophy and four main symptoms of atrophic vaginitis including dysuria, dyspareunia, vaginal itching, and dryness were evaluated and compared before and after treatment. In addition, patients were asked regarding user-friendliness and hygienic issues of medications. Results: Both vaginal estrogen cream and Vagifem significantly improved symptoms of atrophic vaginitis but in terms of effectiveness for the treatment symptoms of atrophic vaginitis, there was no significant difference between the two medications. Vagifem compared to estrogen cream resulted in significantly lower rate of hygienic problems (0% versus 23%, P < 0.001, and was reported by the patients as a significantly easier method of treatment (90% versus 55%, P < 0.0001. Conclusion: This investigation showed that Vagifem is an appropriate medication for the treatment of atrophic vaginitis, which is as effective as vaginal estrogen creams and is more user-friendly.

    A 76-year-old female patient was admitted to the Level I Emergency Department of University of Szeged with severe abdominal pain and vomiting. The clinical assessment with laboratory tests and radiological investigations confirmed severe sepsis associated with intravascular hemolysis and multiorgan failure and acute pancreatitis. On the abdominal CT, besides of other abnormalities, the presence of gas bubbles in the stomach, small intestines and liver were seen. The gastric alterations pointed to emphysematous gastritis. Despite of the medical treatment, the patient's condition quickly deteriorated and eight hours after admission the patient died. The autopsy evaluation revealed systemic infection of abdominal origin caused by gas-producing Gram-positive bacteria, and the post-mortem microbiological cultures confirmed the presence of Cloctridium perfringens in many abdominal organs. Emphysematous gastritis seemed to be the primary infectious focus. PMID:27036998

    Emphysematous gastritis is a rare and frequently fatal condition caused by invasion of gas-forming bacteria into the gastric wall. There have only been a handful of reported cases in the paediatric population, and none of these have evidence of candidal infection or mucormycosis. Patients typically present with abdominal pain, vomiting, malaena and haematemesis. Risk factors for emphysematous gastritis are those that interfere with the natural barriers to infection in the stomach. Diagnosis is made on the basis of typical appearances on abdominal CT. Treatment is generally conservative with surgery reserved for failed medical management or later complications. Antimicrobial cover should be broad with a low threshold for antifungals. It is important to look for predisposing factors for this condition, perhaps including an assessment of the patient's immunocompetency. We present a 16-year-old boy with global developmental delay who presented with this condition associated with candidal infection. PMID:25213783

    A 72-year-old woman underwent irradiation of 46 Grey in total dose, for lumbago of the advanced pancreatic cancer in August 2000. She was admitted to our hospital due to severe anemia in February 2001 with occasionally positive fecal occult blood. Endoscopy revealed erosive gastric mucosa diffuse in the lower body of the stomach, which resulted from radiation. We applied argon plasma coagulation (APC) in March 2001 and succeeded in hemostasis of the widely spreading radiation hemorrhagic gastritis. The progress of the severe anemia improved without cicatricial stenosis. As the coagulation of the APC is limited in the surface mucosa, APC is an easy and effective treatment for radiation hemorrhagic gastritis. (author)

  14. The relationship between Helicobacter pylori-associated gastritis or ulcer disease and gastric emptying

    International Nuclear Information System (INIS)

    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 (14C 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 14C UBT patients or in the incidence of abnormal 14C 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.)

    Sarcina are gram-positive anaerobic bacteria found to be associated with delayed gastric emptying and gastric outlet obstruction. We describe two cases of Sarcina co-existing with Helicobacter pylori organisms in pediatric siblings presenting within four months of each other with pyloric obstruction secondary to severe gastritis/duodenitis. The co-existence of Sarcina and Helicobacter pylori has not, to our knowledge, been previously reported. Its characteristic tetrad packeted morphology per...

  1. Gastritis caused by ingestion of eggs of puffer fish : a case report

    International Nuclear Information System (INIS)

    Tetrodotoxin is a neurotoxin, so gastrointestinal symptoms are very rare; these described in the literature are merely nausea and vomiting. Severe complications in the gastrointestinal tract caused by tetrodotoxin have not been radiologically reported. US and CT show thickening of the gastric wall and contraction of the lumen, and upper gastrointestinal series show shortening, lobulation and irregularity of the lesser and greater curvature of the body and antrum similar to the findings of corrosive gastritis

    Full Text Available This study aims to investigate the sensitization of human skin points along certain meridians related to visceral disease by using the pressure-pain threshold (PPT as an indicator. We detected and compared the PPTs of people with and without gastric ulcer or gastritis on the related acupoints, abdomen area, and back area with von Frey detector and observed the similarities and differences under their respective physiological and pathological states. The results showed that (1 the PPTs of patients with gastric ulcer on related acupoints decreased significantly compared with the control group; (2 there was no significant difference in PPT between the chosen points of the measured meridian and the adjacent nonacupoints; (3 there was an apparent distribution of tender points on the relevant abdomen and back regions of patients with gastric ulcer or gastritis, but none was found on the control group; (4 the pain-sensitive points of gastric ulcer and gastritis patients were BURONG (ST19, LIANGMEN (ST21, and HUAROUMEN (ST24 of the stomach meridian on the abdominal region and PISHU (BL20, WEISHU (BL21, and WEICANG (BL50 on the back, among others The results suggest that the practical significance of acupoints may lie in its role as a relatively sensitive functional area. In a pathological state, the reflex points on the skin which are related to certain visceral organs become sensitive and functionally intensify.

    Full Text Available AIM: To assess expression of matrix metalloproteinases 2 (MMP2 and MMP9 in gastric cancer, superficial gastritis and normal mucosa, and to measure metalloproteinase activity.METHODS: MMP2 and MMP9 mRNA expression was determined by quantitative real-time polymerase chain reaction. Normalization was carried out using three different factors. Proteins were analyzed by quantitative gelatin zymography (qGZ.RESULTS: 18S ribosomal RNA (18SRNA was very highly expressed, while hypoxanthine ribosyltransferase-1 (HPRT-1 was moderately expressed. MMP2 was highly expressed, while MMP9 was not detected or lowly expressed in normal tissues, moderately or highly expressed in gastritis and highly expressed in cancer. Relative expression of 18SRNA and HPRT-1 showed no significant differences. Significant differences in MMP2 and MMP9 were found between cancer and normal tissue, but not between gastritis and normal tissue. Absolute quantification of MMP9 echoed this pattern, but differential expression of MMP2 proved conflictive. Analysis by qGZ indicated significant differences between cancer and normal tissue in MMP-2, total MMP-9, 250 and 110 kDa bands.CONCLUSION: MMP9 expression is enhanced in gastric cancer compared to normal mucosa; interpretation of differential expression of MMP2 is difficult to establish.

  4. Helicobacter-pylori Negative Gastritis in Children—A New Clinical Enigma

    Full Text Available The decrease in the prevalence of Helicobacter pylori (Hp infection in children in the world gave rise to a new pathological finding termed as Hp-negative gastritis. Unfortunately, the term “Hp-negative gastritis” has not been identified as a pathological process and has the status of a “second cousin”; in most publications it was never mentioned as a subject to be dealt with, but was “left over” data that was never the topic of the manuscripts’ discussions. Only recently has the topic captured the attention of the pathologists who described this phenomenon in adults, yet the pathological and/or clinical spectrum or significance of this phenomenon has not been adequately investigated. In the current manuscript we describe Hp-negative gastritis in children, summarize its clinical prevalence and touch upon the possible etiology, pathology, and/or therapeutic implication. Overall, this review has concluded that Hp-negative gastritis is a pathological phenomenon in children that needs further investigation, and to date, as the title suggests, is a new clinical enigma that needs to be considered.

    2016-04-01

    Sleeve gastrectomy specimens are increasingly common surgical specimens received for examination following bariatric surgery for weight loss. The spectrum of pathological changes seen in these cases is not well documented. Retrospective examination was undertaken of 1463 consecutive sleeve gastrectomy specimens received at Envoi Specialist Pathologists. Most cases showed no pathological changes (80.2%). The most common changes seen were non-specific, non-Helicobacter associated chronic gastritis (7.2%), Helicobacter associated gastritis (6.8%) and benign fundic gland polyps (4.0%). Other, rarer changes were lymphocytic gastritis, autoimmune atrophic gastritis, chronic gastritis with intestinal metaplasia, hyperplastic polyps, pancreatic heterotopia, gastrointestinal stromal tumours (GISTs) and a leiomyoma. A wide range of pathological changes are seen in resection specimens following sleeve gastrectomies for weight loss. Many cases will require further treatment or ongoing investigation and surveillance. PMID:27020497

    This paper presents the treatment results and experiences gained from a retrospective study of patients treated with the IMZ osseo-integrated implant system and mandibular overdentures. Patients experiencing problems wearing conventional dentures were assessed by the implant team and 65 cases were treated with 154 endosseous implants placed in the edentulous mandible. Two to four implants were placed in each case and in addition some patients have had augmentation of the mandible with hydroxyapatite. The definitive mandibular prostheses were supported by both implants and the residual ridges. A variety of retention systems were utilised, which included different types of bar and clip, stud attachments, and magnets. The patients have been followed up regularly and evaluated after periods of between one and six years. Six implants have failed over this time resulting in a success rate of over 96%. Most patients expressed a high degree of satisfaction with their new overdentures. There was, however, a considerable burden of maintenance care required for the patient group examined. The findings demonstrate that implant retained overdentures offer a highly effective means of oral rehabilitation for the atrophic mandible, restoring both oral function and facial form.

    Whether or not the atrophic skeletal muscle induces insulin resistance and its mechanisms are not resolved now. The antigravity soleus muscle showed a progressive atrophy in 1-week, 2-week, and 4-week tail-suspended rats. Hyperinsulinemic-euglycemic clamp showed that the steady-state glucose infusion rate was lower in 4-week tail-suspended rats than that in the control rats. The glucose uptake rates under insulin- or contraction-stimulation were significantly decreased in 4-week unloaded soleus muscle. The key protein expressions of IRS-1, PI3K, and Akt on the insulin-dependent pathway and of AMPK, ERK, and p38 on the insulin-independent pathway were unchanged in unloaded soleus muscle. The unchanged phosphorylation of Akt and p38 suggested that the activity of two signal pathways was not altered in unloaded soleus muscle. The AS160 and GLUT4 expression on the common downstream pathway also was not changed in unloaded soleus muscle. But the GLUT4 translocation to sarcolemma was inhibited during insulin stimulation in unloaded soleus muscle. The above results suggest that hindlimb unloading in tail-suspended rat induces atrophy in antigravity soleus muscle. The impaired GLUT4 translocation to sarcolemma under insulin stimulation may mediate insulin resistance in unloaded soleus muscle and further affect the insulin sensitivity of whole body in tail-suspended rats.

    Full Text Available Purpose. This systematic review was aimed at assessing the feasibility by means of survival rate, histologic analysis, and causes of failure of allogeneic block grafts for augmenting the atrophic maxilla. Material and Methods. A literature search was conducted by one reviewer in several databases. Articles were included in this systematic review if they were human clinical trials in which outcomes of allogeneic bone block grafts were studied by means of survival rate. In addition other factors were extracted in order to assess their influence upon graft failure. Results. Fifteen articles fulfilled the inclusion criteria and subsequently were analyzed in this systematic review. A total of 361 block grafts could be followed 4 to 9 months after the surgery, of which 9 (2.4% failed within 1 month to 2 months after the surgery. Additionally, a weighed mean 4.79 mm (95% CI: 4.51–5.08 horizontal bone gain was computed from 119 grafted sites in 5 studies. Regarding implant cumulative survival rate, the weighed mean was 96.9% (95% CI: 92.8–98.7%, computed from 228 implants over a mean follow-up period of 23.9 months. Histologic analysis showed that allogeneic block grafts behave differently in the early stages of healing when compared to autogenous block grafts. Conclusion. Atrophied maxillary reconstruction with allogeneic bone block grafts represents a reliable option as shown by low block graft failure rate, minimal resorption, and high implant survival rate.

    Introduction A rare case of hemorrhagic gastritis induced by radiation is presented, which was resistant to conservative treatment and required subtotal gastrectomy. Presentation of case A 56-year-old male was initially undergone right hepatectomy, resection of the extrahepatic biliary tree, hilar lymph node dissection and hepatico-jejunostomy due to advanced hilar cholangiocarcinoma. Because of the extent of the disease, chemo-radiotherapy was administered. The patient received a total radiotherapy dose of 57.6 Gy in 32 sessions. Unfortunately, diffused hemorrhagic gastritis induced by radiation was developed, which was resistant to conservative treatment (endoscopic hemostasis, transfusion). A subtotal gastrectomy was performed. The patient is in good condition 45 months after the liver resection, but with local recurrence. Conclusion In resistant situations to conservative treatment and recurred bleeding of diffused hemorrhagic gastritis induced by radiation, surgical management may have a role. PMID:26686486

    Full Text Available El dolor abdominal recurrente afecta aproximadamente al 12 % de la población pediátrica mundial. La endoscopia con biopsia gástrica y prueba de ureasa han sugerido que este dolor se relaciona con gastritis nodular asociada a infección por Helicobacter pylori (Hp. Se realizó un estudio en 66 niños entre 7 y 15 años de edad y de ambos sexos, ingresados en 9 hospitales cubanos con el objetivo de evaluar el efecto del Q-Ulcer (subcitrato de bismuto coloidal y metronidazol en pacientes con diagnóstico endoscópico de gastritis crónica asociada a infección por Hp. Se realizó endoscopia, examen histológico y evaluación clínica antes de comenzar el tratamiento y 4 semanas después de haber finalizado. En treinta y cuatro de estos pacientes se erradicó el Hp con remisión de la gastritis. De los 28 pacientes restantes 14 se incluyeron en la categoría de mejorados y 14 en la de sin respuesta, debido a que el microorganismo se mantuvo positivo, aunque en menor densidad. Los eventos adversos se presentaron en aproximadamente la mitad de los niños y fundamentalmente, durante las dos primeras semanas de tratamiento en que la terapia era combinada. Por esta razón, no se puede precisar que fuera el Q-Ulcer el único responsable de la presencia de estos síntomas, ya que a partir de la tercera semana no se presentaron con la misma frecuencia. La terapia combinada de Q-Ulcer y metronidazol garantizó una apreciable mejoría clínica, endoscópica e histológica, a la vez que resultó segura en el tratamiento de niños portadores de gastritis.

    The authors investigated whether the associations between HLA alleles of patients with autoimmune hypothyroidism varied according to the presence or absence of TSH receptor-blocking antibody (TRBab). They analyzed the HLA-A, -B, -C, and -DR antigens by serotyping and the DQA1 and DQB1 genes using both enzymatic DNA amplification and sequence-specific oligonucleotide hybridizations. The patient population consisted of 47 Korean patients with atrophic autoimmune thyroiditis and 62 patients with goitrous autoimmune thyroiditis. The antigen frequency of HLA-DR8 was significantly increased in 23 atrophic autoimmune thyroiditis patients that were positive for TSH binding inhibitor immunoglobulin (TBII) compared to 136 controls [52% vs. 16%; x[sup 2] = 13.1; Pc (corrected P value) = 0.003]. This relative risk was 5.7; the etiological fraction was 0.43. HLA-DQB1*0302 was also increased in patients with TBII-positive atrophic autoimmune thyroiditis (24% vs. 7%; x[sup 2] = 11.2; Pc = 0.012; relative risk = 4.4; etiological fraction = 0.19). No specific DR antigens or DQB1 alleles were increased in either TBII-negative atrophic autoimmune thyroidities or goitrous autoimmune thyroiditis. A significant decrease in the frequency of HLA-DR6 antigen was observed in both TBII-positive atrophic antoimmune thyroiditis (0% vs. 32%; x[sup 2] = 8.4; Pc = 0.03) and goitrous autoimmune thyroiditis (0% vs. 32%; x[sup 2] = 23.2; Pc < 0.001) patients. The frequency of the HLC-Cwl antigen was significantly increased in all patient groups. The authors conclude that TRBab-positive atrophic autoimmune thyroiditis is immunogenetically different from both goitrous autoimmune thyroiditis and TRBab-negative atrophic autoimmune thyroiditis. It is possible that HLA-DR8 and/or DQB1*0302 may be related to the susceptibility genes involved in the production of TRBab in Koreans. 32 refs., 5 tabs.

Because standard diagnostic techniques might provide falsely negative results, we evaluated the sonication method for detection of bacteria on implants of patients with fracture nonunions. A total of 49 patients with a nonunion (group NU and, for comparison, 45 patients who had undergone routine removal of osteosynthetic material (group OM, were included in the study. Five different diagnostic methods (culture of tissue samples, culture of intraoperative swabs, histopathology of tissue samples, culture of sonication fluid, and 16S ribosomal DNA polymerase chain reaction of sonication fluid were compared and related to clinical data. Among the diagnostic tests, culture of sonication fluid demonstrated by far the highest detection rate of bacteria (57% in group NU, and rather unexpectedly 40% in group OM. Culture of sonication samples also revealed a broad spectrum of bacteria, in particular Propionibacterium spp. In conclusion, our results indicate that more bacteria can be detected on implants of patients with atrophic nonunions of long-bone fractures by means of the sonication procedure, which provides a valuable additional diagnostic tool to decide on a surgical procedure (eg, two-step procedure and to further specify antimicrobial therapy.

    Full Text Available Aim: To evaluate the efficacy of the treatment method of autogenous iliac wing or radius bone graft and fixation with screw applied to cases of scaphoid non-union. Material and Method: A retrospective evaluation was made of 89 cases between 2000 and 2014. Postoperative measurements were taken of both wrists%u2019 movement with a goniometer and muscle strength was assessed with a dynamometer. Fractures were evaluated radiologically according to the Herbert-Fisher System and the functional results according to the Herbert-Fisher Classification System and the Mayo Clinic Modified Wrist Scoring System. The data were input to the SPSS system and evaluated with the Shapiro-Wilk test. Results: Non-union were on the right side in 47 and the left side in 42 cases. The fracture was seen to be in the waist in 60 cases (67.5%, in the proximal third in 27 cases (30.3% and in the distal third in two cases (2.2%. The mean follow-up period was 16.4 months (range, 5-72 months. Definitive findings of union were observed in 71 cases. The mean time to union was 14.9 weeks (range, 8-40 weeks. Discussion: The grafting procedure applied is an invasive technique but if it is considered that there are negative effects of open surgery on the feeding of the scaphoid bone, then in the treatment of scaphoid non-union which is atrophic non-union, ultimately autogenous bone grafting and screw fixation is a safe and successful method and because of the pain created by an iliac wing graft, radius distal bone graft can be considered more appropriate.

    Full Text Available Background/Aim: Helicobacter pylori ( H. pylori infection causes peptic ulceration and gastric adenocarcinoma. In Iraq, gastric cancer is rare. We investigated whether infected adults had the antral-predominant pattern of H. pylori -associated gastritis, which does not predispose to cancer. Materials and Methods: We evaluated histopathological changes by the Sydney scoring system in gastric biopsies taken from 30 H. pylori -infected adults and studied the correlation of these changes with the virulence factors. The Mann-Whitney test was used for the comparison of histopathological data. The presence or absence of each pathological index was evaluated with respect to the possession of virulence factors by the infecting H. pylori strain using the χ2 test. Results: Gastric lymphocyte infiltration was more prominent in the antrum ( P = 0.01. Neutrophil infiltration was mild and gastric mucosal atrophy was rare. No relationship was found between virulence factors and histopathological changes. Conclusions: The mild pathology and antral-predominant gastritis help explain the low cancer rate in Iraq.

  2. Bacterial microbiota profiling in gastritis without Helicobacter pylori infection or non-steroidal anti-inflammatory drug use.

    Directory of Open Access Journals (Sweden)

    Xiao-Xing Li

    Full Text Available Recent 16S ribosomal RNA gene (rRNA molecular profiling of the stomach mucosa revealed a surprising complexity of microbiota. Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID use are two main contributors to gastritis and peptic ulcer. However, little is known about the association between other members of the stomach microbiota and gastric diseases. In this study, cloning and sequencing of the 16S rRNA was used to profile the stomach microbiota from normal and gastritis patients. One hundred and thirty three phylotypes from eight bacterial phyla were identified. The stomach microbiota was found to be closely adhered to the mucosa. Eleven Streptococcus phylotypes were successfully cultivated from the biopsies. One to two genera represented a majority of clones within any of the identified phyla. We further developed two real-time quantitative PCR assays to quantify the relative abundance of the Firmicutes phylum and the Streptococcus genus. Significantly higher abundance of the Firmicutes phylum and the Streptococcus genus within the Firmicutes phylum was observed in patients with antral gastritis, compared with normal controls. This study suggests that the genus taxon level can largely represent much higher taxa such as the phylum. The clinical relevance and the mechanism underlying the altered microbiota composition in gastritis require further functional studies.

    Full Text Available We retrospectively reviewed a new preimplantation regenerative augmentation technique for a severely atrophic posterior maxilla using sinus lifting with simultaneous alveolar distraction, together with long-term oral rehabilitation with implants. We also analyzed the regenerated bone histomorphologically. This study included 25 maxillary sinus sites in 17 patients. The technique consisted of alveolar osteotomy combined with simultaneous sinus lifting. After sufficient sinus lifting, a track-type vertical alveolar distractor was placed. Following a latent period, patient self-distraction was started. After the required augmentation was achieved, the distractor was left in place to allow consolidation. The distractor was then removed, and osseointegrated implants (average of 3.2 implants per sinus site, 80 implants were placed. Bone for histomorphometric analysis was sampled from six patients and compared with samples collected after sinus lifting alone as controls (n=4. A sufficient alveolus was regenerated, and all patients achieved stable oral rehabilitation. The implant survival rate was 96.3% (77/80 after an average postloading followup of 47.5 months. Good bone regeneration was observed in a morphological study, with no significant difference in the rate of bone formation compared with control samples. This new regenerative technique could be a useful option for a severely atrophic maxilla requiring implant rehabilitation.

    Full Text Available La Gastritis Crónica Atrófica, de alta incidencia en la infección por Helicobacter pylori, no ha tenido hasta hoy mecanismos patogénicos establecidos. La Gastritis por Helicobacter pylori, claramente relacionada a la Gastritis Crónica Activa Superficial, no ha encontrado mecanismos que la conecten con la Gastritis Crónica Atrófica. Hasta hace poco, eran consideradas por algunos autores como lesiones independientes. En el presente trabajo, se estudiaron 42 biopsias gástricas antrales o corporales, con Gastritis Crónica Atrófica en diferentes estadíos. Las lesiones histológicas que comprenden a esta última, van desde la "infiltración linfoide profunda" en las glándulas gástricas propias, hasta el reemplazo de las mismas por tejido fibroinflamatorio. Por métodos inmunohistoquímicos, hemos podido comprobar que las células linfoides que infiltran el estrato glandular propio del estómago están conformadas por linfocitos T CD8+ (citotóxicos y por células linfocíticas B secretoras de anticuerpos. Planteamos en el presente trabajo que, los linfocitos T citotóxicos agredirían a las glándulas propias antrales y corporales destruyéndolas y produciendo de esta forma su reemplazo por tejido fibroinflamatorio. Similares acciones se producirían por linfocitos B, pero a través de la secreción de anticuerpos locales contra células epiteliales glandulares gástricas.

    Muscle unloading due to long-term exposure of weightlessness or simulated weightlessness causes atrophy, loss of functional capacity, impaired locomotor coordination, and decreased resistance to fatigue in the antigravity muscles of the lower limbs. Besides reducing astronauts' mobility in space and on returning to a gravity environment, the molecular mechanisms for the adaptation of skeletal muscle to unloading also play an important medical role in conditions such as disuse and paralysis. The tail-suspended rat model was used to simulate the effects of weightlessness on skeletal muscles and to induce muscle unloading in the rat hindlimb. Our series studies have shown that the maximum of twitch tension and the twitch duration decreased significantly in the atrophic soleus muscles, the maximal tension of high-frequency tetanic contraction was significantly reduced in 2-week unloaded soleus muscles, however, the fatigability of high-frequency tetanic contraction increased after one week of unloading. The maximal isometric tension of intermittent tetanic contraction at optimal stimulating frequency did not alter in 1- and 2-week unloaded soleus, but significantly decreased in 4-week unloaded soleus. The 1-week unloaded soleus, but not extensor digitorum longus (EDL), was more susceptible to fatigue during intermittent tetanic contraction than the synchronous controls. The changes in K+ channel characteristics may increase the fatigability during high-frequency tetanic contraction in atrophic soleus muscles. High fatigability of intermittent tetanic contraction may be involved in enhanced activity of sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) and switching from slow to fast isoform of myosin heavy chain, tropomyosin, troponin I and T subunit in atrophic soleus muscles. Unloaded soleus muscle also showed a decreased protein level of neuronal nitric oxide synthase (nNOS), and the reduction in nNOS-derived NO increased frequency of calcium sparks and elevated

    The sequence of events associated with the development of gastric cancer has been described as "the gastric precancerous cascade". This cascade is a dynamic process that includes lesions, such as atrophic gastritis, intestinal metaplasia and dysplasia. According to this model, Helicobacter pylori (H. pylori) infection targets the normal gastric mucosa causing non-atrophic gastritis, an initiating lesion that can be cured by clearing H. pylori with antibiotics or that may then linger in the case of chronic infection and progress to atrophic gastritis. The presence of virulence factors in the infecting H. pylori drives the carcinogenesis process. Independent epidemiological and animal studies have confirmed the sequential progression of these precancerous lesions. Particularly long-term follow-up studies estimated a risk of 0.1% for atrophic gastritis/intestinal metaplasia and 6% in case of dysplasia for the long-term development of gastric cancer. With this in mind, a better understanding of the genetic and epigenetic changes associated with progression of the cascade is critical in determining the risk of gastric cancer associated with H. pylori infection. In this review, we will summarize some of the most relevant mechanisms and focus predominantly but not exclusively on the discussion of gene promoter methylation and miRNAs in this context.

    Full Text Available Las hazañas trascendentales alcanzadas por la gastroenterología en los últimos cien años han sido mere-cedoras de tres premios Nobel de Medicina y apreciadas por millones de pacientes con úlcera alrededor del mundo. En 1904 Pavlov es premiado por describir los mecanismos neuro-reflejos de la secreción del ácido clorhídrico y en 1988 el equipo de Black por el descubrimiento de los antagonistas de los receptores H2 de histamina. De manera inesperada Marshall y Warren, dos investigadores clínicos australianos reciben el Premio Nobel en el año 2005 por encontrar que el Helicobacter pylori está relacionado con la patogénesis de la gastritis y úlcera péptica. Las investigaciones posteriores a los descubrimientos de Pavlov complementan el conocimiento de la fisiología gástrica al describir los componentes hormonales (gastrina y humorales (histamina de la secreción gástrica. Se propone que la úlcera péptica es consecuencia del exceso de ácido clorhídrico en el estómago y el planteamiento realizado por Schwartz en 1910 guiará el tratamiento de la úlcera péptica durante muchos años. Sin ácido no hay úlcera. La cirugía con sus diversas técnicas de vagotomía no logra el control de la úlcera péptica. Este fracaso impulsa a los farmacólogos a profundizar en el conocimiento de los mecanismos de control hormonal y humoral de la secreción gástrica. Como resultado se desarrollan los medicamentos que bloquean los receptores H2 expresados por las células parietales del estómago, los cuales al ser activados, inducen a las células a producir ácido. Es irónico que Sir James W. Black ganara el Premio Nobel de Medicina en 1988 por el descubrimiento de estos receptores. Su trabajo preparó el camino para el desarrollo de los bloqueadores H2 de histamina y los inhibidores de la bomba de protones. Tales drogas cambiaron el manejo de la enfermedad y finalmente la cirugía quedó limitada a los casos de perforación gástrica. De

    Reflux gastritis is a kind of pathological duodenal gastric regurgitation(DGR),in which the duodenal content is refluxed into the stomach caused by the primary or secondary factors,also called bile reflux gastritis(BRG). This disease is characterized as long duration of sickness and repeated attacks,develo-ping in tendency as from bile reflux gastritis to superficial gastritis,to atrophy,to intestinal metaplasia,to a-typical hyperplasia and gastric cancer. Taught by the academician,Dong Jianhua,Prof. Yang Jinxiang has ac-cumulated rich experiences in the treatment of BRG with TCM. Prof. Yang believes that“disharmony of gall-bladder and stomach”is the basic etiology and pathogenesis of the occurrence and development of reflux gas-tritis. The treatment should focus on regulating the functions of gallbladder and stomach and descending qi. For example,in the case of reversed gallbladder qi attaching stomach and disharmony of ascending and de-scending,the treatment should be harmonizing Shaoyang and regulating stomach qi with modified xiaochaihu tang and xiangsu san. In the case of heat stagnation in gallbladder and stomach and interaction of phlegm and food retention,the treatment should be benefiting gallbladder qi,harmonizing stomach qi,promoting digestion, clearing heat and resolving phlegm with modified haoqin qingdan tang. In the case of chronic sickness with blood stagnation in the interior,the treatment should be activating blood circulation,removing stasis,benefi-ting qi and harmonizing stomach with modified baihe wuyao tang. In the case of stomach yin insufficiency and dysfunction of gallbladder,the treatment should be nourishing yin,benefiting stomach and gallbladder and stopping pain with modified yiguan jian.%反流性胃炎是由于原发或继发因素导致十二指肠内容物反流入胃的一种病理性十二指肠胃反流(DGR),也称为胆汁反流性胃炎(BRG)。该病病程较长,具有反复发作的

    The implant-supported fixed rehabilitation of patients with an atrophic edentulous crest remains a challenge if bone augmentation is not planned. A minimal intervention approach for bone regeneration is necessary to minimize the flap overextension needed to close the defect over the augmented bone. Prosthetically guided bone regeneration can determine the amount of bone augmentation necessary for definitive prosthetic fixed rehabilitation. The positions of the implants and prosthetic restoration were planned; a 0.3 mm thick titanium mesh was customized for bone augmentation by using computer-aided design and computer-aided manufacturing and rapid prototyped by laser sintering, and the definitive prosthetic rehabilitation was carried out according to the initial treatment plan. This resulted in minimal bone augmentation relative to the functional needs of the definitive prosthetic rehabilitation. PMID:25862269

    Full Text Available BACKGROUND: Helicobacter pylori is a non-invasive microorganism causing intense gastric mucosal inflammatory and immune reaction. The gastric mucosal levels of the proinflammatory cytokines Interleukin 6 (IL-6 and IL-8 have been reported to be increased in H. pylori infection, but the serum levels in H. pylori infection is still controversial. The purpose of this study was to investigate the serum levels of IL-6 and IL-8 in H. pylori infection. METHODS: A cross sectional study was done on eighty consecutive gastritis patients admitted to endoscopy units at Adam Malik General Hospital and Permata Bunda Hospital, Medan, Indonesia from May-October 2014. Histopathology was performed for the diagnosis of gastritis. Rapid urease test for diagnosis of H. pylori infection. Serum samples were obtained to determine circulating IL-6 and IL-8. Univariate and bivariate analysis (independent t test were done. RESULTS: There were 41.25% patients infected with H. pylori. Circulatory IL-6 levels were significantly higher in H. pylori-infected patients compared to H. pylori negative, but there were no differences between serum levels of IL-8 in H. pylori positive and negative patients. CONCLUSIONS: The immune response to H. pylori promotes systemic inflammation, which was reflected in an increased level of serum IL-6. Serum levels of IL-8 were not significantly different between H. pylori positive and negative. KEYWORDS: Helicobacter pylori, gastritis, IL-6, IL-8, cytokine.

    AIM: To investigate the prevalence of H pylori associated corpus-predominant gastritis (CPG) or pangastritis, severe atrophy, and intestinal metaplasia (IM) in patients without any significant abnormal findings during upper GI endoscopy.METHODS: Gastric biopsies from 3548 patients were obtained during upper GI-endoscopy in a 4-year period. Two biopsies from antrum and corpus were histologically assessed according to the updated Sydney-System.Eight hundred and forty-five patients (mean age 54.8 ±2.8 years) with H pylori infection and no peptic ulcer or abnormal gross findings in the stomach were identified and analyzed according to gastritis phenotypes using different scoring systems.RESULTS: The prevalence of severe H pylori associated changes like pangastritis, CPG, IM, and severe atrophy increased with age, reaching a level of 20% in patients of the age group over 45 years. No differences in frequencies between genders were observed. The prevalence of IM had the highest increase, being 4-fold higher at the age of 65 years versus in individuals less than 45 years.CONCLUSION: The prevalence of gastritis featuring at risk for cancer development increases with age. These findings reinforce the necessity for the histological assessment, even in subjects with normal endoscopic appearance. The age-dependent increase in prevalence of severe histopathological changes in gastric mucosa, however, does not allow estimating the individual risk for gastric cancer development-only a proper follow-up can provide this information.

  1. Morphological peculiarities of chronic gastritis in children and adolescents of Belarus under conditions of low dose radiation-chemical exposure

    International Nuclear Information System (INIS)

    Following the accident at the Chernobyl nuclear power station, the unfavourable ecological situation due to chemical contamination of the environment was aggravated by the radiation effect. At present, radionuclides of caesium and lead, as well as the nitrates, are the most widely distributed ecotoxicants. Under conditions of the negative ecological effect as the result of per os penetration of the majority of xenobiotics, the gastro-intestinal tract is at particular risk. During 1990-1994, 442 children and adolescents aged 10-17 residing at the ecologically different regions of the Republic have been examined. The program of examination included morphological investigation of bioptates of the stomach mucous membrane, determination of the radiocaesium specific activity in the body and the evaluation of lead content in blood and nitrates content in urine.

    We report a case of multiple duodenal, pancreatic, and gastric carcinoids. A 67-year old woman was admitted to our hospital for treatment of a duodenal carcinoid.Laboratory tests revealed that the patient was associated with macrocytic anemia and hypergastrinemia, and type A gastritis was shown by gastrofiberscopy.During surgery, another tumor was incidentally found in the head of the pancreas. The tumors in the duodenum and pancreas were completely excised by pancreatoduodenectomy and immunohistologically diagnosed as gastrin-and serotonin-producing carcinoids,respectively. Pathological examination revealed that in addition to the grossly found carcinoids, there were subclinical carcinoids, one of which was an endocrine cell micronest, located in the stomach and duodenum.The tumors in the duodenum, pancreas, and stomach showed different characteristics from one another morphologically and immunochemically. Although no definitive evidence has been obtained, some sort of genetic anomaly may have been involved in this case,and hypergastrinemia due to duodenal gastrinoma may induce multiple gastric carcinoids.

    Full Text Available Gastritis, vomition and weight loss are common in captive cheetahs (Acinonyx jubatus. Gastric spiral bacteria (Helicobacter spp. and the very small, viviparous nematode Ollulanus tricuspis, a stomach worm of cats, are believed to be important causes. Three sibling cheetahs at Wellington Zoo, New Zealand, developed chronic vomiting, diarrhoea and debility. Their parents were both South African-born. Response to antibacterial treatment was poor. Endoscopic examinations revealed chronic lymphoplasmacytic gastritis and Ollulanus infection. Treatment with oxfendazole and pyrantel embonate resulted in clinical improvement; however, 1 cheetah, which died 7 months later as a result of a ruptured liver due to hepatic amyloidosis, still had Ollulanus worms present in her stomach. Ollulanus tricuspis is a significant cause of gastritis and vomiting in captive cheetahs, lions and tigers, as well as wild cougars and tigers. The parasite has not yet been found in sub-Saharan Africa. Because of the unusual characteristics of this parasite, the literature on its life history and techniques for diagnosis is reviewed.

    2003-01-01

    AIM: To identify the expression of Caspase-l(interleukin1.β converting enzyme) and its role in adenoma of the pancreas and chronic pancreatitis.METHODS: The expression of Caspase-1 was assessed in 42 pancreatic cancer tissue samples, 38 chronic pancreatitis specimens, and 9 normal pancreatic tissues by immunohistochemistry and Western blot analysis.RESULTS: Overexpression of Caspase-1 was observed in both disorders, but there were differences in the expression patterns in distinct morphologic compartments. Pancreatic cancer tissues showed a clear cytoplasmatic overexpression of Caspase-1 in tumor cells of 71% of the tumors, whereas normal pancreatic tissues showed only occasional immunoreactivity. In chronic pancreatitis, overexpression of Caspase-1 was found in atrophic acinar cells (89 %),hyperplastic ducts (87 %), and dedifferentiating acinar cells (84 %). Although in atrophic cells a clear nuclear expression was found, hyperplastic ducts and dedifferentiating acinar cells showed dear cytoplasmic expression. Western blot analysis revealed a marked expression of the 45 kDa precursor of Caspase-1 in pancreatic cancer and chronic pancreatitis (80 %and 86 %, respectively). Clear bands at 30 kDa, which suggested the p10-p20 heterodimer of active Caspase-1, were found in 60 % of the cancer tissue and 14 % of the pancreatitis tissue specimens, but not in normal pancreatic tissues.CONCLUSION: Overexpression of Caspase-1 is a frequent event in pancreatic disorders and its differential expression patterns may reflect two functions of the protease. One is its participation in the apoptotic pathway in atrophic acinar cells and tumor-surrounding pancreatitis tissue, the other is its possible role in proliferative processes in pancreatic cancer cells and hyperplastic duct cells and dedifferentiating acinar cells in chronic pancreatitis.

    Full Text Available Abstract Background Real-time PCR is a reliable tool with which to measure mRNA transcripts, and provides valuable information on gene expression profiles. Endogenous controls such as housekeeping genes are used to normalise mRNA levels between samples for sensitive comparisons of mRNA transcription. Selection of the most stable control gene(s is therefore critical for the reliable interpretation of gene expression data. For the purpose of this study, 7 commonly used housekeeping genes were investigated in salivary submandibular glands under normal, inflamed, atrophic and regenerative states. Results The program NormFinder identified the suitability of HPRT to use as a single gene for normalisation within the normal, inflamed and regenerative states, and GAPDH in the atrophic state. For normalisation to multiple housekeeping genes, for each individual state, the optimal number of housekeeping genes as given by geNorm was: ACTB/UBC in the normal, ACTB/YWHAZ in the inflamed, ACTB/HPRT in the atrophic and ACTB/GAPDH in the regenerative state. The most stable housekeeping gene identified between states (compared to normal was UBC. However, ACTB, identified as one of the most stably expressed genes within states, was found to be one of the most variable between states. Furthermore we demonstrated that normalising between states to ACTB, rather than UBC, introduced an approximately 3 fold magnitude of error. Conclusion Using NormFinder, our studies demonstrated the suitability of HPRT to use as a single gene for normalisation within the normal, inflamed and regenerative groups and GAPDH in the atrophic group. However, if normalising to multiple housekeeping genes, we recommend normalising to those identified by geNorm. For normalisation across the physiological states, we recommend the use of UBC.

    We evaluated atrophic changes of brain stem and the degree of symptoms from the ataxia rating scale in 13 cases of Machado-Joseph disease (MJD) and 10 cases of olivopontocerebellar atrophy (OPCA). Patients with MJD and OPCA and normal controls were examined using 1.5-T MRI. Furthermore, we evaluated 3 cases of each two groups with a long-term follow-up study. We used International Cooperative Ataxia Rating Scale (ICARS) for the evaluation of ataxia. The MRI of patients with MJD disclosed remarkably reduced width of the middle cerebellar peduncles and the dilatation of 4th ventricle, which correlated with the limb ataxia in ICARS. On the other hand, the MRI of patients with OPCA revealed diminished anteroposterior and transverse diameters of the pons. The latter of which correlated inversely with the total ICARS. In long-term follow up, MJD showed slow progression of atrophic change and clinical course contrasted to OPCA. In conclusion, we suggested that atrophic changes of brain stem of MJD and OPCA were well correlated with ataxia rating scale, ICARS. (author)

    Gastric cancer remains a prevalent disease worldwide with a poor prognosis. Helicobacter pylori plays a major role in gastric carcinogenesis. H. pylori colonization leads to chronic gastritis, which predisposes to atrophic gastritis, intestinal metaplasia, dysplasia, and eventually gastric cancer. Screening, treatment, and prevention of H. pylori colonization can reduce the incidence of gastric cancer. Other interventions that may yield a similar effect, although of smaller magnitude, include promotion of a healthy lifestyle including dietary measures, non-smoking, low alcohol intake, and sufficient physical activity. This chapter reviews interventions that can lead to a decline in gastric cancer incidence in high and low incidence countries. PMID:27184043

  9. Avoiding osseous grafting in the atrophic posterior mandible for implant-supported fixed partial dentures: a report of 2 cases.

    Bone atrophy occurs after tooth extraction in the posterior mandible, placing the mandibular canal and its neural, arterial, and venous contents closer to the osseous facial aspect and the coronal crest. This proximity places the structure in danger of damage when dental implants are surgically placed to support fixed or removable prostheses. Several options are available to treat these areas for implant-supported fixed and removable complete or partial dentures. Osseous grafting and ridge expansion are surgical options that enable acceptance of standard sized dental implants but have serious morbidities. Additionally, vertical osseous augmentation is not predictable at this time. Narrow diameter dental implants can be placed to avoid the mandibular canal, but some bone volume situations preclude this. Very wide and very short (6.5 × 5 mm) dental implants may be placed at an angle in atrophic sites to successfully support fixed partial dentures. An anterior guidance occlusal scheme may be used in maxillary dentate patients or group function in maxillary complete denture patients. A 100 micron occlusal relief in fixed partial dentures in dentate patients may be required to account for natural tooth intrusion and to prevent occlusal overload of the implant-supported partial denture.

    Three short fragments of recombinant subunit Pasteurella multocida toxin (rsPMT) were constructed for evaluation as candidate vaccines against progressive atrophic rhinitis (PAR) of swine. PMT-specific antibody secreting cells and evidence of cellular immunity were detected in rsPMT-immunized pigs following authentic PMT challenge or homologous antigen booster. Piglets immunized with rsPMT fragments containing either the N-terminal or the C-terminal portions of PMT developed high titers of neutralizing antibodies. Pregnant sows immunized with rsPMT had higher levels of maternal antibodies in their colostrum than did those immunized with a conventional PAR-toxoid vaccine. Offspring from rsPMT vaccinated sows had better survival after challenge with a five-fold lethal dose of authentic PMT and had better growth performance after challenge with a sublethal dose of toxin. Our findings indicate these non-toxic rsPMT proteins are attractive candidates for development of a subunit vaccine against PAR in pigs.

    The edentulous anterior atrophic maxilla represents a challenge for the surgeon and restorative dentist. Soft- and hard-tissue augmentation procedures are often required prior to, or simultaneously with, implant placement. A well-planned treatment protocol, patient compliance, and collaboration between the treating clinicians and the laboratory are requirements in achieving predictable long-term outcomes that satisfy patient expectations. Avoiding transmucosal loading and movement of the graft during the healing phase are crucial factors in achieving lasting success. In this case report, a fixed provisional restoration supported by four immediately loaded narrow-diameter implants (NDIs) was used to enable function during healing and protect the grafted site. Two of the NDIs, along with three conventional-diameter implants, were subsequently used to support the final restoration. NDIs with diameters of less than 3 mm can achieve excellent long-term osseointegration and may be used together with conventional implants for definitive prosthodontic treatment as demonstrated by the 11-year follow-up reported in this case.

    In adult mice thymectomized at age 3 days (D3TX), increased incidences and/or levels of organ-specific antibodies to oocytes and/or zona pellucida, to testicular cell-sperm-differentiation antigens (TSDA), and to gastric parietal cells were detected, and these correlated significantly with oophoritis, orchitis (not epididymovasitis), and gastritis, respectively. The autoantibodies occurred in mice with the corresponding endogenous antigens. Thus, anti-oocyte/zona antibodies were detected in female, anti-TSDA antibodies in male, and anti-parietal cell antibodies in both sexes. Anti-oocyte/zona antibodies were first detected at age 5-6 weeks and were absent by 25 weeks. Serum antizona antibodies, but not anti-oocyte antibodies, inhibited mouse fertilization in vitro. In contrast, antibodies to sperm acrosome and antibodies to sperm surface did not correlate with testicular or epididymal disease. Moreover, both male and female mice had increased levels of anti-sperm surface antibodies, indicating that the sperm antigens detected may not be organ-specific. In addition, sera from 5-10% of D3TX mice reacted with a wide spectrum of epididymal and testicular antigens with defined cellular locations but of yet unknown specificity. Although the incidence of antibodies to cytoskeletal antigens was not significantly elevated after D3TX, anti-nuclear antibodies were more frequently detected in (SWR/J X A/J) F1 (SWRAF1) and (C57 BL/6J X A/J) F1 (B6AF1) mice after D3TX.

    AIM: To evaluate the furazolidone-based triple therapy in children with symptomatic H pylori gastritis.METHODS: A prospective and consecutive open trial was carried out. The study included 38 patients withupper digestive symptoms sufficiently severe to warrant endoscopic investigation.H pylori status was defined based both on histology and on positive 13C-urea breath test. Drug regimen was a seven-day course of omeprazole, clarithromycin and furazolidone (100 mg, 200 mg if over 30 kg) twice daily. Eradication of H pylori was assessed two months after treatment by histology and 13C-urea breath test. Further clinical evaluation was performed 7 d, 2 and 6 mo after the treatment. RESULTS: Thirty-eight patients (24 females, 14 males)were included. Their age ranged from 4 to 17.8 (mean 10.9 ± 3.7) years. On intent-to-treat analysis (n = 38),the eradication rate of H pylori was 73.7% (95% CI,65.2%-82%) whereas in per-protocol analysis (n = 33) it was 84.8% (95% CI, 78.5%-91%). All the patients with duodenal ulcer (n = 7) were successfully treated (100% vs 56.2% with antral nodularity). Side effects were reported in 26 patients (68.4%), mainly vomiting (14/26) and abdominal pain (n = 13). Successfully treated dyspeptic patients showed improvement in 78.9% of H pylori-negative patients after six months and in 50% of H pylori-positive patients after six months of treatment.CONCLUSION: Triple therapy with furazolidone achieves moderate efficacy in H pylori treatment. The eradication rate seems to be higher in patients with duodenal ulcer.

    Capsule Endoscopy (CE) was introduced in 2000 and has since become an established diagnostic procedure for the small bowel, colon and esophagus. For the CE examination the patient swallows the capsule, which then travels through the gastrointestinal tract under the influence of the peristaltic movements. CE is not indicated for stomach examination, as the capsule movements can not be controlled from the outside and the entire surface of the stomach can not be reliably covered. Magnetically-guided capsule endoscopy (MGCE) was introduced in 2010. For the MGCE procedure the stomach is filled with water and the capsule is navigated from the outside using an external magnetic field. During the examination the operator can control the motion of the capsule in order to obtain a sufficient number of stomach-surface images with diagnostic value. The quality of the examination depends on the skill of the operator and his ability to detect aspects of interest in real time. We present a novel computer-assisted diagnostic-procedure (CADP) algorithm for indicating gastritis pathologies in the stomach during the examination. Our algorithm is based on pre-processing methods and feature vectors that are suitably chosen for the challenges of the MGCE imaging (suspended particles, bubbles, lighting). An image is classified using an ada-boost trained classifier. For the classifier training, a number of possible features were investigated. Statistical evaluation was conducted to identify relevant features with discriminative potential. The proposed algorithm was tested on 12 video sequences stemming from 6 volunteers. A mean detection rate of 91.17% was achieved during leave-one out cross-validation.

  15. Isocitrate dehydrogenase of Helicobacter pylori potentially induces humoral immune response in subjects with peptic ulcer disease and gastritis.

    Directory of Open Access Journals (Sweden)

    M Abid Hussain

    Full Text Available BACKGROUND: H. pylori causes gastritis and peptic ulcers and is a risk factor for the development of gastric carcinoma. Many of the proteins such as urease, porins, flagellins and toxins such as lipo-polysaccharides have been identified as potential virulence factors which induce proinflammatory reaction. We report immunogenic potentials of isocitrate dehydrogenase (ICD, an important house keeping protein of H. pylori. METHODOLOGY/PRINCIPAL FINDINGS: Amino acid sequences of H. pylori ICD were subjected to in silico analysis for regions with predictably high antigenic indexes. Also, computational modelling of the H. pylori ICD as juxtaposed to the E. coli ICD was carried out to determine levels of structure similarity and the availability of surface exposed motifs, if any. The icd gene was cloned, expressed and purified to a very high homogeneity. Humoral response directed against H. pylori ICD was detected through an enzyme linked immunosorbent assay (ELISA in 82 human subjects comprising of 58 patients with H. pylori associated gastritis or ulcer disease and 24 asymptomatic healthy controls. The H. pylori ICD elicited potentially high humoral immune response and revealed high antibody titers in sera corresponding to endoscopically-confirmed gastritis and ulcer disease subjects. However, urea-breath-test negative healthy control samples and asymptomatic control samples did not reveal any detectable immune responses. The ELISA for proinflammatory cytokine IL-8 did not exhibit any significant proinflammatory activity of ICD. CONCLUSIONS/SIGNIFICANCE: ICD of H. pylori is an immunogen which interacts with the host immune system subsequent to a possible autolytic-release and thereby significantly elicits humoral responses in individuals with invasive H. pylori infection. However, ICD could not significantly stimulate IL8 induction in a cultured macrophage cell line (THP1 and therefore, may not be a notable proinflammatory agent.

    Gastric cancer (GC) is one of the leading causes of cancer related death in the world, particularly in East Asia. According to the Correa’s cancer cascade, non-cardia GC is usually developed through a series of mucosal changes from non-atrophic gastritis to atrophic gastritis (AG), intestinal metaplasia (IM), dysplasia and adenocarcinoma. Atrophic gastritis and IM are therefore generally considered to be pre-neoplastic gastric lesions. Helicobacter pylori (H. pylori) infection is an important...

    AIM: To assess the possibility of non-invasive screening of atrophic chronic gastritis for preventing further development of gastric cancer.METHODS: One hundred and seventy-eight consecutive Helicobacter pylori ( H pylori)-positive dyspeptic patients after detection of serum levels of pepsinogen-1 (PG-1) and gastrin-17 (G-17) by enzyme immunoassay were proposed for endoscopy and histology. The serologic and morphologic results were compared with estimating the sensitivity,specificity and prognostic values of the tests.RESULTS: There was statistically significant reverse dependence between the grade of stomach mucosal antral or corpus atrophy and the proper decreasing of serum G17or PG1 levels. The serologic method was quite sensitive in the diagnosis of non-atrophic and severe antral and corpus gastritis. Also, it was characterized by the high positive and negative prognostic values.CONCLUSION: Detection of serum G-17 and PG1 levels can be offered as the screening tool for atrophic gastritis. The positive serologic results require further chromoendoscopy with mucosal biopsy, for revealing probable progressing of atrophic process with development of intestinal metaplasia,dysplasia or gastric cancer.

    Full Text Available Impaired bone healing can have devastating consequences for the patient. Clinically relevant animal models are necessary to understand the pathology of impaired bone healing. In this study, two impaired healing models, a hypertrophic and an atrophic non-union, were compared to physiological bone healing in rats. The aim was to provide detailed information about differences in gene expression, vascularization and histology during the healing process. The change from a closed fracture (healing control group to an open osteotomy (hypertrophy group led to prolonged healing with reduced mineralized bridging after 42 days. RT-PCR data revealed higher gene expression of most tested osteogenic and angiogenic factors in the hypertrophy group at day 14. After 42 days a significant reduction of gene expression was seen for Bmp4 and Bambi in this group. The inhibition of angiogenesis by Fumagillin (atrophy group decreased the formation of new blood vessels and led to a non-healing situation with diminished chondrogenesis. RT-PCR results showed an attempt towards overcoming the early perturbance by significant up regulation of the angiogenic regulators Vegfa, Angiopoietin 2 and Fgf1 at day 7 and a further continuous increase of Fgf1, -2 and Angiopoietin 2 over time. However µCT angiograms showed incomplete recovery after 42 days. Furthermore, lower expression values were detected for the Bmps at day 14 and 21. The Bmp antagonists Dan and Twsg1 tended to be higher expressed in the atrophy group at day 42. In conclusion, the investigated animal models are suitable models to mimic human fracture healing complications and can be used for longitudinal studies. Analyzing osteogenic and angiogenic signaling patterns, clear changes in expression were identified between these three healing models, revealing the importance of a coordinated interplay of different factors to allow successful bone healing.

    2014-01-01

    Full Text Available Introduction: Acne scars are largely preventable complications of acne. 95% of the scars occur over the face thus impacting the quality of life. Correction of scars is the priority for acne patients. Materials and Methods: Thirty patients with post acne atrophic facial scars attending the OPD during the period from April to October 2013 were offered four sittings of microneedling with PRP on one side and microneedling with vitamin C on other side of the face at an interval of 1 month. Results: Twenty-seven out of the total 30 patients completed the treatment schedule. Two patients were lost to follow up and one dropped out of the study due to severe PIH. Mean age of the patients was 27.5 years. Out of 30 patients, 23 achieved reduction in scarring by one or two grades. Excellent response was seen in five (18.5% patients with platelet-rich plasma (PRP as compared to two (7% patients who received treatment with vitamin C according to physician′s assessment. As far as up gradation by 1 score is considered, i.e., good response, it was similar in both cases. Vitamin C did not prove to be as efficacious as PRP since 10 (37% patients had poor response in vitamin C-treated area compared to only 6 (22.2% patients who underwent PRP therapy, but vitamin C proved to be efficacious in dealing with post inflammatory hyper-pigmentation secondary to acne. Patients were more satisfied with PRP as compared to vitamin C. The results were evaluated and statistical analysis was done using SPSS 16.0.2. Conclusions: Overall results were better with microneedling and PRP. Vitamin C combined with microneedling also showed improvement with respect to firmness and smoothness of skin; as well as post inflammatory hyper-pigmentation. Microneedling combined with PRP proved to be good in treating boxcar and rolling scars but had limited efficacy in dealing with ice pick scars.

    Amyloidosis is a rare disease caused by extracellular deposits of insoluble fibrillar proteins in various organs and tissues. There are different forms of amyloidosis distinguished by the type of protein fibrils, by the sites of deposition and by associated conditions. Gastrointestinal involvement is common both in primary and secondary amyloidosis, while isolated gastrointestinal amyloidosis is rare. We describe a case of AL amyloidosis with a gastrointestinal involvement and restrictive cardiomiopathy. A 64 year old woman came to our attention with a history of chronic diarrhoea and weight loss, associated with dysphagia, dry mouth, xerophtalmia, chronic gastritis and depression. Clinical diagnosis has been difficult because of aspecificity of symptoms that mimed other more common diseases, like gastro-paresis, epigastric discomfort, gastric or duodenal ulcers, perforation, malabsorption, intestinal pseudo-obstruction. There is an important risk of misunderstanding and diagnostic delay. Indeed in this patient a diagnosis of irritable colon syndrome was erroneously established two years before admission in our hospital. Therefore gastrointestinal amyloidosis should be considered among differential diagnoses of chronic diarrhoea and weight loss when other more common diseases have been excluded. PMID:19530511

    Objective: To study the rule of development of early cancer of gastric cardiac in vivo. Methods: A prospective cohort was held in the high incidence area of cancer of esophagus and stomach in china. One hundred and six persons were examined regularly by endoscopy to observe the change of pro-cancer lesions of gastric cardiac by taking biopsy specimen. All specimens were diagnosed through normal pathological process. Results: The 106 subjects were examined twice in 1998 and 2002. Of 8 normal persons, 3 stayed normal, 4 turned to chronic gastritis, 1 developed early gastric cardiac cancer. Of 61 persons with chronic gastritis, 11 were observed to have gland atrophy, 4 with mild atypical hyperplasia, and 2 with highly atypical hyperplasia. Of 9 subjects showing atrophic chronic gastritis, 5 revealed no change, and 4 became chronic gastritis. Of 22 subjects who revealed mild atypical hyperplasia, 17 resolved, 4 showed no change, and 1 advanced to highly atypical hyperplasia. One person with highly atypical hyperplasia reverted to mild atypical hyperplasia. Of 5 subjects with early gastric cardiac cancer without any treatment, 1 became advanced cancer, 1 still stayed in early cancer stage, 3 turned to atypical hyperplasia. Conclusion: 1. The development of early cancer of gastric cardia would proceed through the stages of chronic gastritis, gland atrophy, and atypical hyperplasia. 2. The early cancer and pre-cancer lesions of gastric cardia is reversible, though possessing malignant possibility.

    Atrophic age-related macular degeneration (AMD) is associated with the subretinal accumulation of mononuclear phagocytes (MPs). Their role in promoting or inhibiting retinal degeneration is unknown. We here show that atrophic AMD is associated with increased intraocular CCL2 levels and subretinal CCR2(+) inflammatory monocyte infiltration in patients. Using age- and light-induced subretinal inflammation and photoreceptor degeneration in Cx3cr1 knockout mice, we show that subretinal Cx3cr1 deficient MPs overexpress CCL2 and that both the genetic deletion of CCL2 or CCR2 and the pharmacological inhibition of CCR2 prevent inflammatory monocyte recruitment, MP accumulation and photoreceptor degeneration in vivo. Our study shows that contrary to CCR2 and CCL2, CX3CR1 is constitutively expressed in the retina where it represses the expression of CCL2 and the recruitment of neurotoxic inflammatory CCR2(+) monocytes. CCL2/CCR2 inhibition might represent a powerful tool for controlling inflammation and neurodegeneration in AMD. PMID:24142887

    Atrophic age-related macular degeneration (AMD) is associated with the subretinal accumulation of mononuclear phagocytes (MPs). Their role in promoting or inhibiting retinal degeneration is unknown. We here show that atrophic AMD is associated with increased intraocular CCL2 levels and subretinal CCR2+ inflammatory monocyte infiltration in patients. Using age- and light-induced subretinal inflammation and photoreceptor degeneration in Cx3cr1 knockout mice, we show that subretinal Cx3cr1 deficient MPs overexpress CCL2 and that both the genetic deletion of CCL2 or CCR2 and the pharmacological inhibition of CCR2 prevent inflammatory monocyte recruitment, MP accumulation and photoreceptor degeneration in vivo. Our study shows that contrary to CCR2 and CCL2, CX3CR1 is constitutively expressed in the retina where it represses the expression of CCL2 and the recruitment of neurotoxic inflammatory CCR2+ monocytes. CCL2/CCR2 inhibition might represent a powerful tool for controlling inflammation and neurodegeneration in AMD. PMID:24142887

    Full Text Available This report documents the clinical, radiographic, and histologic outcome of a custom-made computer-aided-design/computer-aided-manufactured (CAD/CAM scaffold used for the alveolar ridge augmentation of a severely atrophic anterior mandible. Computed tomographic (CT images of an atrophic anterior mandible were acquired and modified into a 3-dimensional (3D reconstruction model; this was transferred to a CAD program, where a custom-made scaffold was designed. CAM software generated a set of tool-paths for the manufacture of the scaffold on a computer-numerical-control milling machine into the exact shape of the 3D design. A custom-made scaffold was milled from a synthetic micromacroporous biphasic calcium phosphate (BCP block. The scaffold closely matched the shape of the defect: this helped to reduce the time for the surgery and contributed to good healing. One year later, newly formed and well-integrated bone was clinically available, and two implants (AnyRidge, MegaGen, Gyeongbuk, South Korea were placed. The histologic samples retrieved from the implant sites revealed compact mature bone undergoing remodelling, marrow spaces, and newly formed trabecular bone surrounded by residual BCP particles. This study demonstrates that custom-made scaffolds can be fabricated by combining CT scans and CAD/CAM techniques. Further studies on a larger sample of patients are needed to confirm these results.

    Patients who have undergone gastric resection are at higher risk of developing gastric carcinoma than normal subjects, and bile reflux is believed to play a role in carcinogenesis. An increase in mucosal cell proliferation increases the likelihood of a neoplastic clone of epithelial cells emerging, particularly where there is chronic epithelial injury associated with bile reflux. Helicobacter pylori is considered a major risk factor for gastric cancer in the intact stomach. It has been shown ...

  17. Chronic migraine.

    Chronic migraine is a disabling neurologic condition that affects 2% of the general population. Patients with chronic migraine have headaches on at least 15 days a month, with at least eight days a month on which their headaches and associated symptoms meet diagnostic criteria for migraine. Chronic migraine places an enormous burden on patients owing to frequent headaches; hypersensitivity to visual, auditory, and olfactory stimuli; nausea; and vomiting. It also affects society through direct and indirect medical costs. Chronic migraine typically develops after a slow increase in headache frequency over months to years. Several factors are associated with an increased risk of transforming to chronic migraine. The diagnosis requires a carefully performed patient interview and neurologic examination, sometimes combined with additional diagnostic tests, to differentiate chronic migraine from secondary headache disorders and other primary chronic headaches of long duration. Treatment takes a multifaceted approach that may include risk factor modification, avoidance of migraine triggers, drug and non-drug based prophylaxis, and abortive migraine treatment, the frequency of which is limited to avoid drug overuse. This article provides an overview of current knowledge regarding chronic migraine, including epidemiology, risk factors for its development, pathophysiology, diagnosis, management, and guidelines. The future of chronic migraine treatment and research is also discussed. PMID:24662044

    A double-blind, randomized trial was undertaken to compare the clinical, endoscopic and histological response to 6-weeks' treatment with hydrotalcite/dimethicone suspension or magnesium hydroxide/aluminum hydroxide suspension in 36 patients with symptomatic gastritis. Significantly more patients (P less than 0.05) showed symptomatic improvement in the antacid-treated group than in the hydrotalcite/dimethicone-treated group and more had a reduction in histological inflammatory scores (P less than 0.01), although there was little correlation between histology and symptoms. There was no evidence from this study that the bile acid binding and anti-foaming properties of hydrotalcite/dimethicone suspension were of any benefit in the treatment of patients with symptomatic gastritis.

    AIM: To investigate the expression profiles of hsa-miR-29c and hsa-miR-135b in gastric mucosal samples and their values as gastric carcinogenesis biomarkers. METHODS: The expression levels of hsa-miR-29c and hsa-miR-135b in normal gastric mucosa, non-atrophic chronic gastritis, intestinal metaplasia and intestinal-type gastric adenocarcinoma were analysed using quantitative real-time PCR. The difference between hsa-miR-29c and hsa-miR-135b expression profiles in the grouped samples was evaluated by ANOVA and Student’s t-test tests. The results were adjusted for multiple testing by using Bonferroni’s correction. P values ≤ 0.05 were considered statistically significant. To evaluate hsa-miR-29c and hsa-miR-135b expressions as potential biomarkers of gastric carcinogenesis, we performed a receiver operating characteristic curve analysis and the derived area under the curve, and a Categorical Principal Components Analysis. In silico identification of the genetic targets of hsa-miR-29c and hsa-miR-135b was performed using different prediction tools, in order to identify possible genes involved in gastric carcinogenesis. RESULTS: The expression levels of hsa-miR-29c were higher in normal gastric mucosal samples, and decreased progressively in non-atrophic chronic gastritis samples, intestinal metaplasia samples and intestinal-type gastric adenocarcinoma samples. The expression of hsa-miR-29c in the gastric lesions showed that non-atrophic gastritis have an intermediate profile to gastric normal mucosa and intestinal-type gastric adenocarcinoma, and that intestinal metaplasia samples presented an expression pattern similar to that in intestinal-type gastric adenocarcinoma. This microRNA (miRNA) has a good discriminatory accuracy between normal gastric samples and (1) intestinal-type gastric adenocarcinoma; and (2) intestinal metaplasia, and regulates the DMNT3A oncogene. hsa-miR-135b is up-regulated in non-atrophic chronic gastritis and intestinal metaplasia samples
