Discussion on the mechanism of Ganwei Baihe Decoction in treating gastric ulcer based on bioinformatics and experimental validation / 国际中医中药杂志

Objective:To study the potential mechanism of Ganwei Baihe Decoction in the treatment of gastric ulcer (GU) based on bioinformatics and validate it through animal experiments.Methods:TCMSP, DisGeNET, and GeneCards databases were used to retrieved active components and action targets of Ganwei Baihe Decoction. After obtaining the intersection, protein interaction data of the intersection genes were obtained through the STRING database. A PPI network was constructed by Cytoscape 3.10.0 software and the key genes and key components were obtained. DAVID online analysis database was used for GO functional enrichment and KEGG pathway enrichment analysis of key targets. Animal experiments were used for verification. Totally 36 SD rats were divided into blank group, model group, Omeprazole group and Ganwei Baihe Decoction group according to the random number table method, with 9 rats in each group. After 7 days of gavage of the corresponding drugs to each group of rats, they fasted and but with water for 24 hours, and then re-gavaged once. After 1 hour of administration, a gastric ulcer rat model was prepared by gavage of 80 mg/kg of indomethacin. After 3 hours of administration, anesthesia was used to extract the sample. The expression level of Caspase-3 protein in the gastric tissue of rats was to be determined by Western blot method.Results:There were 234 effective active components with 290 targets in Ganwei Baihe Decoction, and 6 496 therapeutic targets for GU. 213 potential targets for GU were screened out. There were 437 GO function and 153 KEGG pathway enriched entries. Compared with the model group, the protein expression of Caspase-3 in the Ganwei Baihe Decoction group and Omeprazole group decreased ( P<0.05). Conclusion:The mechanism of Ganwei Baihe Decoction in treating GU may be through key components such as quercetin and β-sitosterol acting on key targets such as AKT1 and CASP3, regulating the Apoptosis pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, etc. to exert inhibitory effects on apoptosis.

Efficacy of omeprazole and sodium bicarbonate suspension in the treatment of peptic ulcer: a multicenter clinical trial / 中华消化杂志

Objective:To evaluate the efficacy and safety of omeprazole and sodium bicarbonate suspension in the treatment of peptic ulcer.Methods:This present study was a multicenter, randomized, double-blind, double-dummy, positive drug parallel controlled phase Ⅱ clinical trial. According to different indications, the trial was divided into gastric ulcer (GU) and duodenal ulcer (DU) studies. Patients were stratified-block randomly divided with a 1∶1 ratio into experimental group and control group. The patients in the experimental group were administrated with omeprazole and sodium bicarbonate suspension omeprazole (20 mg for DU or 40 mg for GU, and 1 680 mg sodium bicarbonate) once a day. The patients in the control group received omeprazole magnesium enteric-coated tablet20 mg for DU or 40 mg for GU once a day. The treatment period was 4 weeks for DU and 8 weeks for GU. The main efficacy indicator was ulcer healing rate under endoscopy. The time of pain disappearance and the total effective rate of clinical symptom relief were used as the secondary efficacy indicators, and the incidence of adverse reactions was used as the safety indicator. The data set included full analysis set (FAS), per-protocol set (PPS) and safety set (SS). Independent sample t test, Wilcoxon rank sum test, chi square test, Fisher exact test method and non-inferiority test were used for statistical analysis. Results:Two hundred and seventy two DU patients and 237 GU patients were included in the FAS, 247 DU patients and 201 GU patients were included in the PPS, and 272 DU patients and 235 GU patients were included in the SS. The results of FAS analysis showed that after 4 weeks treatment, the healing rate of DU under endoscopy in the experimental group was 91.91% (125/136) and that in the control group was 94.85% (129/136), and the difference was not statistically significant ( P>0.05). After 8 weeks treatment the healing rate of GU under endoscopy in the experimental group was 86.44% (102/118) and that in the control group was 87.39% (104/119), and the difference was not statistically significant ( P>0.05). The results of non-inferiority analysis showed the lower limit of 95% confidence interval of difference in effective rate between the two groups was over -10% (-8.84% for DU and -9.54% for GU), which indicated that the effective rate of experimental group was not inferior to that of the control group. The results of PPS analysis were consistent with the results of FAS. The results of FAS analysis showed the median time of abdominal pain disappearance of DU patients in the experimental group and the control group was both 6 d, and the difference was not statistically significant ( P>0.05). The median time of abdominal pain disappearance of GU patients in the experimental group and the control group was both 8 d, and the difference was not statistically significant ( P>0.05). After 4 weeks of treatment, the total effective rates of clinical symptom relief of DU of the trial group and the control group were 95.59% (130/136) and 97.79% (133/136), respectively, and the difference was not statistically significant ( P>0.05). After 8 weeks of treatment, the total effective rates of clinical symptom relief of GU of the experimental group and the control group were 95.76% (113/118) and 93.28% (111/119), respectively, and the difference was not statistically significant ( P>0.05). The results of SS analysis showed that the incidence of adverse reactions of DU patients in the trial group and the control group was 5.15% (7/136) and 2.21% (3/136), respectively, and the difference was not statistically significant ( P>0.05). The incidence of adverse reactions of GU patients in the experimental group and the control group was 12.71% (15/118) and 6.84% (8/117), respectively, and the difference was not statistically significant ( P>0.05). Conclusions:Omeprazole and sodium bicarbonate suspension is not inferior to omeprazole magnesium enteric-coated tablet in healing efficacy under endoscopy in peptic ulcer, and has a good safety.

Controversias en cirugía: Erradicación del Helicobacter pylori ¿Terapia a todos o según indicaciones usuales? / Controversies in surgery: Eradication of Helicobacter pylori. Therapy for all or according to usual indications?

La infección por Helicobacter pylori (H. pylori), es la infección bacteriana crónica más frecuente de la raza humana, afecta al 50 % de la población mundial y, por lo menos, al 80 % de la población colombiana. Esta bacteria es re-conocida desde hace más de 15 años como un carcinógeno tipo I. De acuerdo con las indicaciones del Consenso de "Maastricht V" esta infección debe ser buscada y tratada en los pacientes con úlcera péptica activa, linfoma MALT (por sus siglas en inglés, mucosa associated lymphoid tissue), cáncer gástrico temprano, púrpura que presenten síntomas dispépticos crónicos y usuarios crónicos de AINES. Debido al papel que tiene en la fisiopatología del cáncer gástrico, nace la iniciativa de realizar una búsqueda activa del H. pylori y erradicarlo en todas las personas, incluyendo aquellas asintomáticas en países con alta incidencia de esta neoplasia. Existen diversas publicaciones alrededor del mundo que así lo sugieren, mostrando resultados con impacto positivo en el curso y progresión de la enfermedad, sobre todo en las etapas más tempranas de la infección. Sin embargo, otros autores resaltan la creciente problemática de la resistencia bacteriana, y demuestran que el peso estadístico y los diferentes análisis de los estudios disponibles en la actualidad tienen poca validez para dar una recomendación extendida al paciente asintomático. Se cuestiona que tal vez, estamos utilizando las estrategias inadecuadas para manejar una situación de salud pública, ya que estamos enfocados en impactar a cada individuo con terapias antibióticas complejas, en vez de a la población en general con políticas de salud pública

Helicobacter pylori (H. pylori) infection is the most frequent chronic bacterial infection in humans, affecting 50% of the world population, and at least 80% of the Colombian population. This bacteria has been recognized for more than 15 years as a type I carcinogen. According to the indications of the "Maastricht V" consensus, this infection should be sought and treated in patients with: active peptic ulcer, MALT lymphoma (for its acronym Mucosa associated lymphoid tissue), early gastric cancer, purpura who present with chronic dyspeptic symptoms and chronic users of NSAIDs. Due to the role it plays in the pathophysiology of gastric cancer, the initiative was born to carry out an active search for H. pylori and eradicate it in all people, including those asymptomatic in countries with a high incidence of this neoplasia.There are various publications around the world that suggest the effectiveness of this treatment and the positive impact on the course and progression of the disease, especially in the earliest stages of the infection, since the more advanced stages have less encouraging results regarding progression to malignancy. However, other authors highlight the growing problem of bacterial resistance that we are currently facing and demonstrate that the sta-tistical weight and the different analyzes of the currently available studies have little validity to give an extended recommendation to the asymptomatic patient. It is suggested that perhaps inappropriate strategies to manage this public health situation are being used, since we are focused on impacting each individual with complex antibiotic therapies, instead of the general population with public health policies

Usefulness of Ultrasonography in the Diagnosis of Peptic Ulcer Disease in Children / 대한소아소화기영양학회지

PURPOSE: This study was performed to assess the clinical usefulness of transabdominal ultrasonography (TUS) in detecting peptic ulcer disease (PUD) in children. METHODS: Twenty-four patients (19 boys, 5 girls; mean age, 10.6±4.5 years [range, 3.0–17.9 years]) who were admitted to the hospital for acute abdomen or gastrointestinal bleeding and diagnosed with PUD by endoscopy and who underwent TUS were included. Clinical data were retrospectively collected by reviewing patient medical records. Gastric ulcer (GU) was suspected when the gastric wall exceeded 8 mm in thickness and had lost its five-layer structure on TUS. Duodenal ulcer (DU) was suspected if the duodenal wall thickness exceeded 5 mm. RESULTS: Sensitivity of TUS in diagnosing PUD was 66.7% for GU and 38.9% for DU. Mean age and body weight of the 11 patients suspected with PUD on TUS were 10.9±4.4 years and 38.1±17.2 kg, respectively. For 13 patients without suspected PUD, they were 12.1±4.1 years and 39.6±17.0 kg, respectively. There was a significant difference in height, weight, and body mass index between patients who were suspected to have PUD and those who were not suspected on TUS (p=0.014, 0.008, and 0.005, respectively). A significant difference in the sensitivity of TUS in diagnosing PUD was found between patients under 30 kg and those over 30 kg (88.9% and 20.0%, respectively; p=0.003). CONCLUSION: TUS investigation of the stomach and duodenum is an efficient method for PUD detection in children with low body weight. TUS can be used in preliminary diagnostic work-up before further invasive tests.

Objective@#To analyze the social comparison tendency of patients with chronic gastric ulcer and its influence on self-efficacy.@*Methods@#From April 2016 to June 2018, 320 patients with chronic gastric ulcer admitted to the People's Hospital of Lianshui County were selected by convenient sampling method.All patients were surveyed by the Social Comparing Tendency Scale and Self-efficacy Scale.After the questionnaire was collected, the questionnaire was sorted out by designated personnel, and the influencing factors of self-efficacy were analyzed by single and multiple factors.@*Results@#Univariate analysis showed that the factors influencing self-efficacy of patients with chronic gastric ulcer were marital status, occupational status, religious beliefs, educational level and treatment stage(t=4.285, F=3.085, t=4.121, F=5.056, t=4.376, all P<0.05). The scores of social comparison tendency and self-efficacy of 80 patients with chronic gastric ulcer were (37.42±8.56)points and (236.25±64.25)points.The results of stepwise regression analysis showed that the self-efficacy level of unmarried, low-educated and socially inclined patients was low(t=3.087、3.183、2.231, all P<0.05).@*Conclusion@#Medical staff can guide patients' family members to provide emotional support, relaxed and warm family environment, and according to their social tendency, give appropriate interventions to enhance their self-efficacy.

Benign Gastric Ulcer with Epstein-Barr Virus Infection Mimicking Malignant Gastric Ulcer / 대한소화기학회지

Epstein-Barr virus (EBV) is the cause of infectious mononucleosis, which is characterized by fever, lymphadenopathy, and sore throat. On the other hand, gastrointestinal symptoms of EBV infection like dyspepsia, abdominal pain are non-specific and rarely encountered, which means it is difficult to diagnose gastric involvement of EBV infection without suspicion. The relation between gastric carcinoma and gastric lymphoma associated with EBV infection is well defined, but relations with other EBV-associated gastrointestinal diseases such as gastritis and peptic ulcer disease have rarely been reported. We report a case of benign gastric ulcer with EBV infection confirmed by endoscopic and histological findings.

Gastric Ulcers with Cytomegalovirus Infection in an Immunocompetent Patient

Cases of cytomegalovirus (CMV) infection are rare, and this infection is commonly asymptomatic in immunocompetent patients. Here, we report a pathologically proven case of CMV infection in gastric ulcers in an immunocompetent patient. A 35-year-old man visited our hospital for a surveillance esophagogastroduodenoscopy. Except fatigue, he had no other symptoms. Laboratory data showed that his white cell count was 9.28×10³/µL with 60.1% lymphocytes. However, aspartate transaminase and alanine aminotransferase levels were elevated. Esophagogastroduodenoscopy revealed multiple gastric ulcers that were healing. Two endoscopic biopsies were performed to obtain specimens at the ulcer base. Histological examination and immunohistochemistry confirmed CMV infection; subsequently, we decided that the best option was observation without medication. He revisited a month later, and the ulcers had disappeared.

O mel-derivado de Lactobacillus rhamnosus alivia a infecção gastro-intestinal induzida pelo Helicobacter pylori-e inflamação gástrica em C57Bl/6 ratos: um estudo imuno-histológico / Honey-derived lactobacillus rhamnosus alleviates helicobacter pylori-induced gastro-intestinal infection and gastric inflammation in c57bl/6 mice: an immuno-histologic study

ABSTRACT BACKGROUND: Helicobacter pylori (H. pylori) has been introduced by since 1983 by Marshal and Warren to play the main role in the pathophysiology of gastritis and gastric ulcers. Almost half of the world population1 is infected by H. pylori. Current therapeutic regimen against H. pylori includes the use of a proton pump inhibitor plus two or more antibiotics. However, the efficacy of this regimen is decreasing mainly due to antibiotic resistance and side effects of medications. This fact has resulted in public interest in other therapeutic options and the role of probiotics merits special attention in this regard. OBJECTIVE: This study aims to evaluate the efficacy of honey-derived Lactobacillus rhamnosus on H. pylori-induced gastric inflammation and gastro-intestinal infection in C57BL/6 Mice. METHODS: The 24 C57BL/6 Mice were randomly divided into three groups of eight mice each. All the mice were fed with 1cc suspension containing 5*1010 CFU/ mL of ATCC43504 strains of H. pylori for 3 consecutive days, twice daily via polyethylene gavage tubes. At the end of 4th week, infection with H. pylori was confirmed with stool Ag (ELISA) and following sacrifice of one mouse from each group, histopathologic study confirmed gastritis. The groups were subjected to different therapies as stated, 1: without Bismuth (Bi), Omeprazole (Om) and L. rhamnosus prescription, 2: Bi, Om and Clarithromycin (Cl) and 3: Bi, Om plus 1cc of suspension of 109 CFU/mL of L. rhamnosus. After 2 weeks, the stool was analyzed for Ag and the mice were sacrificed for evaluation of histopathologic changes. RESULTS: Treatment with L. rhamnosus group provided Zero titer of stool Ag and was associated with improved gastric inflammation in all subjects, similar to the clarithromycin group. CONCLUSION: Honey-derived L. rhamnosus probiotics provides similar results as clarithromycin in terms of improvement of H. pylori infection and gastritis in C57BL/6 Mice model, without its cons of antibiotic resistance.

RESUMO CONTEXTO: O Helicobacter pylori (H. pylori) foi reconhecido em 1983 por Marechal e Warren como protagonista principal na fisiopatologia de gastrite e úlceras gástricas. Quase metade da população mundial está infectada por H. pylori. O regime terapêutico atual contra H. pylori inclui o uso de um inibidor da bomba de prótons associada a dois ou mais antibióticos. No entanto, a eficácia deste regime está diminuindo principalmente devido à resistência aos antibióticos e efeitos colaterais de medicamentos. Este fato resultou no interesse público em outras opções terapêuticas e o papel dos probióticos merece atenção especial a este respeito. OBJETIVO: Este estudo visa avaliar a eficácia do mel-derivado do Lactobacillus rhamnosus na inflamação gástrica e infecção gastrointestinal H. pylori-induzida em camundongos C57Bl/6. MÉTODOS: Vinte e quatro camundongos C57Bl/6 foram divididos aleatoriamente em três grupos de oito camundongos cada. Todos os ratos foram alimentados com suspensão de 1cc contendo 5*1010 UFC/mL de cepas ATCC43504 de H. pylori por 3 dias consecutivos, duas vezes por dia através de gavagem por tubos de polietileno. No final da 4ª semana, a infecção com H. pylori foi confirmada pelo antígeno fecal (ELISA) e após o sacrifício de um rato de cada grupo, o estudo histopatológico confirmou gastrite. Os grupos foram submetidos a diferentes terapias, como indicado, 1: sem prescrição de bismuto (BI), Omeprazol (Om) e L. rhamnosus, 2: Bi, Om e claritromicina (CL) e 3: Bi, Om mais 1cc de suspensão de 109 UFC/mL de L. rhamnosus. Após 2 semanas, as fezes foram analisadas para o antígeno e os ratos foram sacrificados para a avaliação das alterações histopatológicas. RESULTADOS: O tratamento com o grupo L. rhamnosus forneceu o título zero de antígeno e foi associado com a inflamação gástrica melhorada em todos os camundongos, similar ao grupo claritromicina. CONCLUSÃO: O probiótico mel-derivado L. rhamnosus fornece resultados semelhantes ao da claritromicina em termos de melhoria da infecção H. pylori e gastrite em C57Bl/6 camundongos modelos, sem os inconvenientes de resistência aos antibióticos.

Gastroprotective and antioxidant effects of Eremurus spectabilis Bieb. methanol extract and its isolated component isoorientin on indomethacin induced gastric ulcers in rats

Abstract Purpose: To investigate the gastroprotective effect of methanol extract of E. spectabilis and its major component isoorientin. Methods: Effects of isoorientin and methanol extract of E. spectabilis were investigated in indomethacin-induced gastric damage model on rats. Famotidine was used as the standard antiulcer drug. Numerical density of ulcer areas and oxidative status were determined on stomach tissues of rats. Results: All doses of isoorientin and methanol extract decreased MDA level and increased SOD activity and GSH levels in the stomach tissue of rats. When numerical density of ulcer areas were analized, the 500 mg/kg dose of methanol extract (84%) exhibited a similar effect to 20 mg/kg dose of standart drug famotidine (87%). Conclusions: The gastroprotective effects of E. spectabilis and its major constituent isoorientin in rats for the first time. Detailed analyses suggested that potential antioxidant activity of both plant extract and isoorientin mediates the gastroprotective effect.

Caso Clínico: Tumor Neuroendocrino Gástrico / Case Report: Gastric Carcinoid

INTRODUCCIÓN: Los tumores neuroendocrinos gástricos son tumores de muy baja prevalencia, constituyendo el aproximadamente 1.8 % de los tumores gástricos. Suelen ser solitarios, con un tamaño entre 4 y 8 cm, con más frecuencia en el sexo masculino con edad promedio de presentación entre 60 - 70 años. Su diagnóstico es cada vez mayor, gracias al uso generalizado de la endoscopia digestiva alta, siendo ésta la prueba de oro. En cuanto a su tratamiento, la resección quirúrgica de los tumores carcinoides gástricos es de elección cuando no se puede optar por resección endoscópica. CASO CLÍNICO: Paciente de 45 años con cuadro clínico de epigastralgia, náusea y diarrea, de dos meses de evolución. Se realiza endoscopía digestiva alta con reporte de úlcera de antro Forrest III. Biopsia: neruroendocrino grado II. Tomografia abdomen: sin datos de actividad en otro sitio fuera de estómago. EVOLUCIÓN: Se realizó gastrectomía subtotal, con reporte negativo en el estudio transoperatorio de líquido de lavado peritoneal. El reporte de patología confirmó el diagnóstico de tumor neuroendócrino GII 3.5 cm unifocal; en estadio III B según las guías clínicas, con vigilancia por un período de un año sin actividad tumoral. CONCLUSIÓN: Al ser el tumor neuroendocrino gástrico un tipo de cáncer poco frecuente, la endoscopía digestiva alta fue fundamental en el diagnóstico de este caso que le llevó al paciente a buscar evaluación médica. Sin embargo, para disminuir el riesgo de su incidencia se recomienda una alimentación rica en frutas, y verduras frescas acompañado de una actividad física adecuada.

BACKGROUND: Gastric neuroendocrine are very low tumors prevalence, constituting approximately 1.8 % of gastric tumors. They are usually solitary, with a size between 4 and 8 cm, most often in the male with average age of presentation between 60 - 70 years. It is diagnosis is increasing, thanks to the widespread use of upper digestive endoscopy, this being the gold standar. Regarding it is treatment; surgical resection of gastric neruroendocrine tumors is one of the choices when endoscopic resection is not possible. CASE REPORT: 45-year-old patient refers epigastralgia, nauseas and diarrhea, since two months ago. Upper digestive endoscopy is performed with report of Forrest III antrum ulcer. Biopsy: grade II neuroendocrine tumor. Abdominal tomography: no activity data in another place outside the stomach. EVOLUTION: Subtotal gastrectomy was performed, with a negative report in the transoperative study of peritoneal lavage fluid. The pathology report confirmed the diagnosis of unifocal neuroendocrine GII 3.5 cm tumor; in stage III B according to clinical guidelines, with surveillance for a period of one year without tumor activity. CONCLUSION: The gastric neuroendocrine is a rare type of cancer; upper gastrointestinal endoscopy was a fundamental in the diagnosis of this case that led the patient to seek medical evaluation. However, to reduce it is incidence is recommended to eat a diet rich in fruits, and fresh vegetables accompanied by adequate physical activity.

Evolution of incidence, mortality and cost of nontraumatic abdominal emergencies treated in Brasil in a period of nine years

SUMMARY OBJECTIVE: To evaluate the incidence, mortality and cost of non-traumatic abdominal emergencies treated in Brazilian emergency departments. METHODS: This paper used DataSus information from 2008 to 2016 (http://www.tabnet.datasus.gov.br). The number of hospitalizations, costs - AIH length of stay and mortality rates were described in acute appendicitis, acute cholecystitis, acute pancreatitis, acute diverticulitis, gastric and duodenal ulcer, and inflammatory intestinal disease. RESULTS: The disease that had the highest growth in hospitalization was diverticular bowel disease with an increase of 68.2%. For the period of nine years, there were no significant changes in the average length of hospital stay, with the highest increase in gastric and duodenal ulcer with a growth of 15.9%. The mortality rate of gastric and duodenal ulcer disease increased by 95.63%, which is significantly high when compared to the other diseases. All had their costs increased but the one that proportionally had the highest increase in the last nine years was the duodenal and gastric ulcer, with an increase of 85.4%. CONCLUSION: Non-traumatic abdominal emergencies are extremely prevalent. Hence, the importance of having updated and comparative data on the mortality rate, number of hospitalization and cost generated by these diseases to provide better healthcare services in public hospitals.

RESUMO OBJETIVO: Avaliar a evolução da Incidência, mortalidade e custo das urgências abdominais não traumáticas atendidas nos serviços de emergência do Brasil durante o período de nove anos. MÉTODOS: Este trabalho utilizou informações do DataSus de 2008 a 2016, (http://www.tabnet.datasus.gov.br).

RESULTADOS: A doença que teve o maior crescimento do número de internações foi a doença diverticular do intestino, com o valor de 68,2%. Ao longo dos nove anos não houve grandes variações da média de permanência hospitalar, sendo que o maior aumento foi o da úlcera gástrica e duodenal, com crescimento de 15,9%. A taxa de mortalidade da doença por úlcera gástrica e duodenal teve um aumento de 95,63%, consideravelmente significante quando comparada com as outras doenças. Todas tiveram seus valores de AIH aumentados, porém, a que proporcionalmente teve o maior aumento nos últimos nove anos foi a úlcera gástrica e duodenal, com um acréscimo de 85,4%. CONCLUSÃO: As urgências abdominais de origem não traumática são de extrema prevalência, por isso a importância em ter dados atualizados e comparativos sobre a taxa de mortalidade, o número de internações e os custos gerados por essas doenças, para melhor planejamento dos serviços públicos de saúde.

Gastric Ulceration and Bleeding with Hemodynamic Instability Caused by an Intragastric Balloon for Weight Loss

Obesity in the United States is a medical crisis with many people attempting to lose weight with caloric restriction. Some patients choose minimally invasive weight loss solutions, such as intragastric balloon systems. These balloon systems were approved by the Federal Drug Administration (FDA) in 2015–2016 and have been considered safe, with minimal side effects. We report a patient with a two-day history of melena, abdominal pain, hypotension, and syncope which developed five months after placement of an intragastric balloon. Esophagogastroduodenoscopy with balloon removal revealed a small 8-mm gastric ulcer in the incisura. This gastric ulcer probably developed secondary to mechanical compression of the stomach mucosa by the gastric balloon which contained 900 mL of saline. The FDA is now investigating five deaths since 2016 associated with these second-generation balloons. Clinicians should be aware of these complications when evaluating patients with gastrointestinal complications, such as bleeding.

Perfil epidemiológico dos pacientes diagnosticados com úlcera gástrica e/ou duodenal em dois serviços de referência do extremo sul catarinense no período de um ano / Epidemiological profile of patients diagnosed with gastric and or duodenal ulcer in two renowned medical centers in the far-south of santa catarina within one year period

Introdução: Úlceras pépticas ainda são um problema de saúde pública, portanto há interesse em obter dados atuais com a finalidade de melhorias nas estratégias de saúde. Objetivos: Conhecer o perfil epidemiológico dos pacientes diagnosticados com úlcera gástrica e/ou duodenal. Metodologia: Foi realizado um estudo observacional, transversal, prospectivo, de abordagem quantitativa, com uma população composta por crianças, adultos e idosos, submetidos ao exame de endoscopia digestiva alta em um serviço de referência público e outro privado do extremo sul catarinense entre agosto de 2012 e agosto de 2013. Resultados: A idade média foi 56,3 (±16,9) anos naqueles diagnosticados com úlceras pépticas, 60,2 (±15,3) anos naqueles com úlcera gástrica e entre os casos de úlcera duodenal, a média foi de 49,4 (±17,9) anos. A presença de H. Pylori, foi confirmada em 57,6% do total de pacientes com úlcera péptica, todavia a presença de H. Pylori variou conforme o tipo de úlcera presente. Entre aqueles com úlcera gástrica, a maioria, 66,7% (IC95% 44,7;88,7), teve resultado negativo para a bactéria, enquanto 33,3% (IC95% 11,3;55,3) apresentaram H. Pylori. Em contrapartida, nos pacientes com úlceras duodenais, a bactéria estava presente em 100% (IC95% 100,0;100,0) dos casos (p=0,001). Conclusão: Foi observada maior frequência de úlceras gástricas em homens, brancos, não tabagistas e não usuários de AINEs. Constatou-se maior presença de H. Pylori naqueles com úlceras duodenais e, dentre as úlceras gástricas, a maioria dos pacientes não apresentou neoplastias ao exame anatomopatológico.

Background: Peptic ulcers currently remain a public health care issue, hence there is interest in obtain current data for improve the health care strategies. Objectives: To acknowledge the epidemiological profile of patients diagnosed with gastric and/or duodenal ulcer via upper endoscopy. Method: An observational, cross-sectional, prospective and quantitative approach was conducted. The population was composed by children, adults and seniors, examined by upper endoscopy in a renown public and a renown private institutions in the far-south of Santa Catarina between August 1st of 2012 and August 1st of 2013. Results: The mean age was 56,3 (±16,9) years old in those diagnosed with peptic ulcers, 60,2 (±15,3) in those diagnosed with gastric ulcer and 49,4 (±17,9) in those diagnosed with duodenal ulcer. The presence of H. Pylori was confirmed in 57,6% of the patients with peptic ulcers, however, the percentage varied according to the type of the ulcer: among those with gastric ulcer, the majority - 66,7% (IC95% 44,7;88,7) ­ shown negative results for H. Pylori while 33,3% (IC95% 11,3;55,3) shown positive test results, indicating the presence of the bacteria. In the other hand, patients with duodenal ulcer had the bacteria in 100% of the cases (p=0,001). Conclusion: It was observed higher frequency of gastric ulcers among men, whites, non-AINEs-users, and non-smokers. Higher prevalence of the H. Pylori was observed in patients with duodenal ulcers. The majority of the patients with gastric ulcers did not show gastric neoplasia in the anatomopathological exam.

Penetrating gastric ulcer as a manifestation of multisystemic tuberculosis / Úlcera gástrica penetrante como manifestación de tuberculosis multisistémica

We present the case of a 30-year old female with a history of abdominal pain, fever, poor oral tolerance and weight loss for 6 months. An abdominal CT scan showed marked gastric dilatation due to extrinsic compression from lymphadenopathies around the second portion of the duodenum. The upper endoscopy revealed the presence of a penetrating gastric ulcer in the greater curvature. Biopsies of the lesions showed hystiocytes with granulomatous features and Acid Fast Bacilli (AFB) positive, and the cultures grew Mycobacterium tuberculosis sensitive to Isonazid and Rifampin. Subsequently anti-TB regimen was initiated achieving great clinical and endoscopic improvement.

Mucosal healing quality of hydrotalcite combined with esomeprazole in gastric ulcer / 中华消化杂志

Objective To explore the mucosal healing quality of hydrotalcite combined with esomeprazole in gastric ulcer.Methods Forty-two patients visiting from June 2014 to December 2015 and diagnosed with gastric ulcer were selected and divided into combination therapy group and single therapy group with 21 patients in each group.The patients of combination therapy group received esomeprazole combined with hydrotalcite,and the patients of single therapy group received esomeprazole alone.The total therapeutic course was eight weeks.At the same period,21 health check-up participants were enrolled as normal control group.The healing of gastric ulcer was observed under white light endoscopy.The morphological changes of gastric pits and microvessel of mucosal at peripheral mucosa around ulcer and normal gastric mucosal were observed under narrow band imaging magnifying endoscopy.The gastric mucosa tissues of the two groups before and after treatment,and normal gastric mucosa of healthy control group were taken.The amount of deposition and composition of collagen fibers,the expression level of factor Ⅷ,the level of transforming growth factor (TGF)-beta1 and the content of hydroxyproline were analyzed by Masson,immunofluorescent and immunohistochemistry staining as well as enzyme linked immunosorbent assay.Chi square test,one-way analysis of variance (ANOVA),least significant difference (LSD) method,Dunnett's T3 and Kruskal-Wallis test and other method were used for comparison.Results After treatment,18 patients of combination therapy group (21 patients) had regular microvessel nets (85.7％),which was significantly more than those of single therapy group (12 cases,57.1％) and healthy control group (10 cases,47.6 ％),and the differences were statistically significant (x2 =4.200,P=0.040).In the comparison of maturity of regenerative mucosa between combination therapy group and single therapy group after treatment,the ration between collagen type Ⅰ and Ⅱ,deposition of collagen fibers,the number of factor Ⅷ positive cells,the level of TGF-beta1 and the content of hydroxyproline were 36.05 and 23.14;269 375.63.± 171 608.63 and 137 693.14±98 330.93;34.91±8.40 and 28.24±6.93;104 498.71±40 487.96 and 70 757.11±19 323.95;(1 897.80±879.35) and (1 230.57±536.05) μg/L,respectively;while in healthy control group,the above parameters were 36.81,245 696.90 ± 224 687.00,23.10 ± 8.40,94 048.04 ±41 306.55 and 1 681.20 ± 423.61 μg/L,and the differences were statitically significant among these three groups (H=7.375,F=3.465,11.680,5.190,5.160;all P＜0.05).Those parameters of combination therapy group were significantly higher than those of single therapy group (H=2.416,LSD method;all P＜0.05).Conclusion Hydrotalcite combined with esomeprazole in the treatment of gastric ulcer could significantly improve microvessel morphology,maturity degree of regenerative mucosal structure and function,and the mucosal healing quality was also superior to single esomeprazole group.

Effects of caspase-1 inhibitor VX765 on cold-restraint stress-induced acute gastric ulcer in mice / 中华烧伤杂志

Objective@#To investigate the protective effects of caspase-1 inhibitor VX765 on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer.@*Methods@#Twenty-four specific pathogen free male C57BL/6J mice were divided into normal control group (NC), cold restrain group (CR), VX765 pre-treatment+ cold restrain group (VCR), and rabeprazole pre-treatment+ cold restrain group (RCR) according to the random number table, with 6 mice in each group. Mice in group NC were injected intraperitoneally with solution of 10 mL/kg dimethylsulfoxide (DMSO) and phosphate buffer solution (PBS). Mice in group CR were inflicted with acute gastric ulcer induced by cold-restraint stress 30 minutes after intraperitoneal injection of solution of DMSO and PBS. Mice in groups VCR and RCR were inflicted with acute gastric ulcer as above 30 minutes after intraperitoneal injection of solution of DMSO and PBS with dose of 12.5 μmol/kg containing 10 mg VX765 and 40 mg/kg containing 20 mg rabeprazole, respectively. Four hour after cold-restraint stress, serum content of tumor necrosis factor alpha (TNF-α) and interleukin 6 (IL-6)was determined by enzyme-linked immunosorbent assay. Gross condition of gastric tissue was observed. Ulcer index was evaluated. Pathological change of gastric tissue was observed with HE staining. The relative expression of IL-1β, IL-18, and cleaved-caspase-1 in gastric tissue were detected by Western blotting. Mice in group NC were detected as above at the same time point. Data were processed with one-way analysis of variance and Bonferroni test.@*Results@#The serum content of TNF-α and IL-6 and the relative expression of cleaved-caspase-1, IL-1β, and IL-18 in gastric tissue of mice in group NC were significantly lower than those in group CR (with P values below 0.01). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group CR (with P values below 0.01). There were no statistically significant differences in content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice between groups RCR and CR (with P values above 0.05). The content of the above-mentioned inflammatory indexes in serum and gastric tissue of mice in group VCR was significantly lower than that in group RCR (with P values below 0.01). Surface of gastric mucosa was smooth and morphology of mucosal cells was normal with clear structure of mice in group NC. Multiple hemorrhage of gastric mucosa, disorderly arrangement of mucosal cells, and large number of inflammatory cell infiltration around necrotic tissue were observed in mice of group CR. Decreased number of gastric mucosa bleeding, intact mucosal structure, and small amount of inflammatory cell infiltration around necrotic tissue were observed in mice of groups VCR and RCR. The ulcer indexes of mice in groups NC, CR, VCR, and RCR were 0, 18.7±1.1, 6.3±1.5, and 8.2±1.3, respectively. The ulcer index of mice in group NC was significantly lower than that in the other 3 groups (with P values below 0.05). The ulcer indexes of mice in groups VCR and RCR were close (P>0.05), which were significantly lower than ulcer index of mice in group CR (with P values below 0.05).@*Conclusions@#VX765 can effectively inhibit the activation of caspase-1, reduce production of inflammatory factor, and alleviate inflammatory response, which have protective effects on gastric mucosa of mice with cold-restraint stress-induced acute gastric ulcer.

Comparison of the Hospital-Acquired Clostridium difficile Infection Risk of Using Proton Pump Inhibitors versus Histamine-2 Receptor Antagonists for Prophylaxis and Treatment of Stress Ulcers: A Systematic Review and Meta-Analysis

BACKGROUND/AIMS: Although proton pump inhibitors (PPIs) have been widely used for the prevention and treatment of stress gastric ulcers in hospital settings, there are concerns that PPIs increase the risk of Clostridium difficile infection (CDI). However, little is known about the risk of CDI following PPI and histamine-2 receptor antagonist (H2RA) use. We evaluated the comparative hospital-acquired CDI occurrence risk associated with the concurrent use of PPIs versus H2RAs. METHODS: A systematic search of PubMed, MEDLINE/Ovid, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and Google Scholar through August 19, 2016, identified 12 studies that reported the hospital-acquired CDI occurrence following H2RA and PPI use for the prevention and treatment of stress gastric ulcers. Random-effects pooled odds ratios and 95% confidence intervals were estimated. Heterogeneity was measured using I², and a meta-regression analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was used to assess the overall quality of the evidence. RESULTS: A total of 74,132 patients from 12 observational studies were analyzed. Compared to H2RAs, PPIs increased the risk of CDI by 38.6% (pooled odds ratio, 1.386; 95% confidence interval, 1.152 to 1.668; p=0.001; I²=42.81%). Subgroup analyses of the purpose of study medication use, study site, and study design confirmed the consistency of a greater CDI risk with PPIs than with H2RAs. The overall quality of evidence was rated as low. CONCLUSIONS: The use of PPIs for both the prevention and treatment of stress ulcers was associated with a 38.6% increased risk of hospital-acquired CDI occurrence compared to H2RA use.
