Tratamiento endoscópico del sangrado digestivo alto por úlcera péptica / Endoscopic treatment of the high digestive bleeding by peptic ulcer

RESUMEN Introducción: la hemorragia digestiva alta ocurre por una lesión sangrante localizada entre el esfínter esofágico superior y el ángulo de Treitz. Objetivo: determinar el comportamiento del tratamiento endoscópico del sangrado digestivo alto por úlcera péptica, en el departamento de Gastroenterología del Hospital Universitario Comandante "Faustino Pérez". Materiales y métodos: se realizó un estudio descriptivo, prospectivo para evaluar el resultado del tratamiento endoscópico en el sangrado digestivo alto por úlcera péptica en el Hospital Universitario Comandante "Faustino Pérez" de Matanzas, de enero del 2016 a febrero del 2018. El tratamiento endoscópico fue la inyectoterapia con epinefrina al 1:10000. Se analizaron las variables: grupo de edades, sexo, resultado del tratamiento endoscópico, estigmas endoscópicos de sangrado, recidiva hemorrágica, mortalidad directa, necesidad de cirugía, estadía hospitalaria y cantidad de unidades transfusionales. Resultados: se constató un predominio de pacientes masculinos (87.5 %), menores de 60 años (70%). Prevalecieron los pacientes con estigmas endoscópicos de sangrado activo venoso (45%). La terapia endoscópica tuvo un resultado satisfactorio (92.5%) en su mayoría. La ocurrencia de resangrado (45%), mortalidad directa por hemorragia digestiva, promedio de estadía hospitalaria, cantidad de unidades transfusionales y necesidad de intervención quirúrgica de urgencia (17.5%), resultó similar a los estudios reportados, demostrando que la inyectoterapia endoscópica aún constituye una opción eficaz si no se cuenta con otras terapias endoscópicas. Conclusiones: la mayoría de los casos tratados con inyectoterapia endoscópica tuvieron un sangrado activo venoso o Forrest IB que fue satisfactoria. La inyectoterapia no satisfactoria fue en pacientes con sangrado activo. La mortalidad directa relacionada con el sangrado fue infrecuente y en relación con el sangrado arterial. Se demostró que la inyectoterapia endoscópica aún constituye una opción eficaz si no se cuenta con otras terapias endoscópicas (AU).

SUMMARY Introduction: high digestive bleeding happens due to a bleeding lesion located between the upper anatomical sphincter of the esophagus and the angle of Treitz. Objective: to determine the endoscopic treatment behavior of high digestive bleeding caused by peptic ulcer, in the department of Gastroenterology of the University Hospital "Comandante Faustino Perez". Materials and methods: a prospective descriptive study was carried out to evaluate the result of the endoscopic treatment in high digestive bleeding caused by peptic ulcer in the University Hospital "Comandante Faustino Perez", of Matanzas, from January 2016 to February 2018. The endoscopic treatment was injecto-therapy with epinephrine at 1:10000. The analyzed variables were: age group, sex, result of the endoscopic treatment, bleeding endoscopic stigma, hemorrhagic relapse, direct mortality, surgery necessity, hospital staying, and quantity of transfusion units. Results: male patients (87.5 %), aged less than 60 years predominated. Patients with endoscopic stigma of venous active bleeding (45 %) prevailed. In most of cases, endoscopic therapy achieved satisfactory results (92.5 %). The authors found that bleeding relapse (45 %), direct mortality by digestive hemorrhage, average hospital staying, quantity of transfusion units and necessity of urgent surgeries (17.5 %) were similar to those reported in other studies. Conclusions: most cases treated with endoscopic injectotherapy had active venous or Forrest IB bleeding and treatment was satisfactory. Therapy was unsatisfactory in patients with active bleeding. The direct mortality related to bleeding was infrequent, and related to arterial bleeding. It was showed that endoscopic injectotherapy is still an efficacious option if other endoscopic therapies are not available (AU).

Nuevos retos en el tratamiento de la infección por helicobacter pylori / New challenges in the treatment of the infection for helicobacter pylori

RESUMEN La infección por helicobacter pylori afecta aproximadamente al 50% de la población mundial, es causante de gastritis crónica, úlcera péptica, cáncer gástrico y linfoma del tejido linfoide asociado a la mucosa. Desde su descubrimiento, la erradicación ha sido uno de los más importantes retos en Gastroenterología. En muchos países se desconoce la prevalencia de resistencia primaria del microorganismo a los diferentes antibióticos que empíricamente se utilizan, y por no realizar pruebas de rutina que verifican su erradicación en la práctica diaria, se ignora la efectividad de los esquemas prescritos. El incremento progresivo de la resistencia a la claritromicina y metronidazol, unido a una ausencia de antibioticoterapia alternativa, desafía la capacidad para eliminar de manera efectiva a ésta bacteria. El subcitrato de bismuto ha resurgido y su adición en la terapia ha permitido aumentar las tasas de curación por encima del 90%. Actualmente se invoca que para mejorar la eficacia en el tratamiento se debe combinar una supresión potente del ácido gástrico en tratamientos combinados cuádruples con una duración de 14 días, para la mayoría de los casos. La adherencia al tratamiento es crucial para obtener buenos resultados terapéuticos.

ABSTRACT The infection for helicobacter pylori affects approximately to the world population's 50%, it is causing of chronic gastritis, peptic ulcer, gastric cancer and linfoma associated to the mucous one. From their discovery, the eradication has been one of the most important challenges in Gastroenterología. In many countries the prevalencia of primary resistance is ignored from the microorganism to the different antibiotics that empirically they are used, and for not carrying out routine tests that verify its eradication in the daily practice, the effectiveness of the prescribed outlines it is ignored. The progressive increment of the resistance to the claritromicina and metronidazol, together to an absence of alternative antibioticotherapy, challenges the capacity to eliminate from an effective way to this bacteria. The bismuth subcitrato has resurged and its addition in the therapy has allowed to increase the cure rates above 90%. At the moment it is invoked that to improve the effectiveness in the treatment, that is should combine a potent suppression of the gastric acid in combined quadruple treatments with a duration of 14 days, for most of the cases. The adherence to the treatment is crucial to obtain therapeutic good results.

Doença ulcerosa péptica: realmente é possível identificá-la por meio das características da dor epigástrica? / Peptic ulcer disease: is it really possible to identify it through the characteristics of epigastric pain?

OBJETIVO: Determinar se características da dor epigástrica são capazes de identificar pacientes com doença ulcerosa péptica. MÉTODOS: Estudo caso-controle, com coleta de dados de setembro de 2014 a junho de 2016. Foram incluídos pacientes com mais de 18 anos com dispepsia que realizaram endoscopia digestiva alta ambulatorialmente. Os pacientes foram abordados antes de realizar a endoscopia digestiva alta, verificando, em suas guias, a presença de dispepsia, tendo sido convidados a responder um questionário, e, posteriormente, o prontuário de cada entrevistado foi avaliado para verificação do diagnóstico, sendo, então, divididos entre o Grupo Doença Ulcerosa Péptica (casos), com 32 pacientes, e o Grupo Controle, com 44 pacientes com dispepsia atribuída a outras causas. RESULTADOS: Dos pacientes com dispepsia não ulcerosa, 52,27% caracterizaram a dor como em queimação, sendo 47,72% moderada e que piorava com alimentação. Dentre os demais sintomas, 45,45% relataram náuseas e 25% desconforto pós-prandial, com 52,27% relatando histórico familiar negativo de doença ulcerosa péptica. Em contrapartida, dos pacientes com doença ulcerosa péptica, 53,12% referiram dor em queimação e de moderada intensidade, e 50% relataram piora com alimentação. Dentre os demais sintomas, prevaleceram também náuseas (53,12%) e desconforto pós-prandial (40,62%). A maioria (81,25%) relatou histórico familiar de doença ulcerosa péptica. Observou-se diferença estatística em dor noturna, predominando na doença ulcerosa péptica (p=0,0225) e dor em cólica na dispepsia não ulcerosa (p=0,0308), assim como na ausência de histórico familiar entre os pacientes com dispepsia não ulcerosa (p=0,0195). CONCLUSÃO: A dispepsia relacionada à doença ulcerosa péptica relaciona-se, principalmente, à piora noturna, sendo que a intensidade da dor, a relação com alimentação e os sintomas associados não auxiliaram na diferenciação da dispepsia não ulcerosa, diferentemente do que a literatura tradicionalmente informa. (AU)

To determine whether it is possible to identify Peptic Ulcer Disease through the characteristics of epigastric pain. METHODS: This is a case-control study with data collected between September 2014 and June 2016 including patients over 18 years of age with dyspepsia who underwent upper gastrointestinal endoscopy as outpatients. The patients were approached before the upper gastrointestinal endoscopy when their test requisition form indicated the presence of dyspepsia. The subjects were invited to answer a questionnaire and, afterwards, the records of all interviewees were evaluated to check for the diagnosis. Then, they were divided into a peptic ulcer disease group (cases), with 32 patients, and a control group, with 44 patients with dyspepsia from other causes. RESULTS: Among non-ulcer dyspepsia patients, 52.27% described the pain as a "burning pain", with 47.72% reporting it as moderate and aggravated by food intake. As for other symptoms, 45.45% of subjects reported nausea, and 25% reported postprandial discomfort; 52.27% had no family history of peptic ulcer disease. In contrast, 53.12% of peptic ulcer disease patients reported "burning" and moderate pain, and 50% said the pain was aggravated by eating. As for the other symptoms, nausea (53.12%) and postprandial discomfort (40.62%) prevailed; most of the patients (81.25%) had family history of peptic ulcer disease. There was a statistical difference in night pain, which was more prevalent in peptic ulcer disease (p=0.0225), and colicky pain, which was more frequent in nonulcer dyspepsia (p=0.0308), as well as absence of family history in non-ulcer dyspepsia patients (p=0.0195). CONCLUSION: Dyspepsia caused by peptic ulcer disease is mainly related to night worsening, and pain intensity, the relationship with food intake, and associated symptoms did not help differentiate nonulcer dyspepsia, differently from what the medical literature traditionally suggests.

Píloro doble: de lo cotidiano a lo extraordinario: reporte de caso y revisión de la literatura / Double pylorus: from the everything to the extraordinary: case report and literature review

Antecedentes: El píloro doble constituye un hallazgo endoscópico extremadamente raro, siendo más frecuente en pacientes que padecen enfermedad ulcerosa péptica. Corresponde a una comunicación anormal entre el antro gástrico y el bulbo duodenal, que puede llegar a requerir tratamiento quirúrgico. Caso clínico: Mujer de 86 años de edad con antecedentes de diabetes mellitus tipo 2, hipertensión arterial, así como ingesta crónica de AINE, portadora de enfermedad ácido-péptica de larga evolución con poca respuesta al manejo médico con bloqueadores H2, la cual presenta sangrado de tubo digestivo durante 5 días caracterizado por hematemesis y melena, así como pirosis, náuseas, sin pérdida ponderal; por este motivo se realiza endoscopia digestiva alta la cual reporta como hallazgos: gastritis erosiva crónica activa secundaria a AINE y asociada a Helicobacter pylori, así como píloro doble adquirido secundario a enfermedad ácido-péptica, sin evidencia de tumores u otras lesiones asociadas. Se inicia esquema de erradicación para H. pylori con amoxicilina y claritromicina durante 14 días, asociados a inhibidor de bomba de protones durante 6-8 semanas con buena respuesta al manejo médico. Discusión: El píloro doble adquirido es una rara complicación de úlcera péptica que puede ser asociada a otras enfermedades, AINE y a la colonización por H. pylori, por lo tanto el adecuado tratamiento consistirá en la corrección de esos factores.

Background: The double pylorus is an extremely rare endoscopic finding, being more frequent in patients suffering from peptic ulcer disease. It corresponds to an abnormal communication between the gastric antrum and the duodenal bulb, which may require surgical treatment. Clinical case: A 86-year-old woman with a history of type 2 diabetes mellitus, hypertension and chronic NSAID intake, a carrier of long-term peptic acid disease with poor response to medical management with H2 blockers. This presents digestive tube bleeding for 5 days characterized by hematemesis and melena, as well as heartburn, nausea, without weight loss, reason why high digestive endoscopy is performed, which reports as findings: active chronic erosive gastritis secondary to NSAIDs and associated with Helicobacter pylori, as well as acquired double pylorus secondary to peptic acid disease, without evidence of tumors or other associated lesions. Eradication scheme begins for H. pylori with amoxicillin and clarithromycin for 14 days, associated with a proton pump inhibitor for 6-8 weeks with good response to medical management. Discussion: The acquired double pylorus is a rare complication of peptic ulcer disease that can be associated with other diseases, NSAIDs and colonization by H. pylori, therefore the appropriate treatment will consist in the correction of these factors.

Surgical outcomes for perforated peptic ulcer: a prospective case series at an academic hospital in Monrovia, Liberia

Introduction The incidence of perforated peptic ulcer remains high in low and middle-income countries. Mortality can be significant; and early surgical management with careful evaluation of pre-operative risk factors is essential. The purpose of this study was to describe the clinical outcomes of surgical treatment for perforated peptic ulcer disease in Liberia and to explore risk factors for adverse outcomes.Methods This study prospectively examined 20 consecutive patients undergoing primary closure with omental patch for perforated pre-pyloric or duodenal peptic ulcer at the John F. Kennedy Medical Centre (JFKMC) in Monrovia; Liberia from May 2009 to March 2010. Pre-operative information was captured in a questionnaire. Risk factors were assessed for univariate and multivariate associations with in-hospital mortality.Results Median age was 33 years and 85 were males. A majority of the patients (70) had a history of gastritis and antacid use. Median time from beginning of symptoms to surgery was 4.5 days. Over-all in-hospital mortality following surgical therapy for perforated peptic ulcer disease was 35. Median length of stay among survivors was 16 days; and death occurred at median 1 day after admission. Long symptom duration and age 30 years of age were significantly associated with in-hospital mortality on univariate (? = 2.60 [0.18-5.03]; p = 0.035) and multivariate testing (? = 2.95 [0.02-5.88]; p =0.049). Conclusion Peptic ulcer disease and its treatment represent a potentially substantial source of morbidity and mortality in limited-resource settings. In this case series; surgical treatment for perforated peptic ulcer disease carried a high mortality; and the results highlight the potential for public health systems strengthening to prevent poor health outcomes. Peptic ulcer disease in low- and middle-income countries presents unique epidemiology and treatment challenges that may differ significantly from evidence-based guidelines in high-income countries

A systematic approach for the diagnosis and treatment of idiopathic peptic ulcers

An idiopathic peptic ulcer is defined as an ulcer with unknown cause or an ulcer that appears to arise spontaneously. The first step in treatment is to exclude common possible causes, including Helicobacter pylori infection, infection with other pathogens, ulcerogenic drugs, and uncommon diseases with upper gastrointestinal manifestations. When all known causes are excluded, a diagnosis of idiopathic peptic ulcer can be made. A patient whose peptic ulcer is idiopathic may have a higher risk for complicated ulcer disease, a poorer response to gastric acid suppressants, and a higher recurrence rate after treatment. Risk factors associated with this disease may include genetic predisposition, older age, chronic mesenteric ischemia, smoking, concomitant diseases, a higher American Society of Anesthesiologists score, and higher stress. Therefore, the diagnosis and management of emerging disease should systematically explore all known causes and treat underlying disease, while including regular endoscopic surveillance to confirm ulcer healing and the use of proton-pump inhibitors on a case-by-case basis.

Caracterización de úlceras gástricas y duodenales / Characterization of gastric and duodenal ulcers

La úlcera péptica es una lesión en la mucosa gastrointestinal (estómago o duodeno) que se extiende más allá de la muscularis mucosae y que permanece como consecuencia de la actividad de la secreción ácida del jugo gástrico. Objetivo: describir las características epidemiológicas y clínicas de las úlceras gástricas y duodenales en pacientes que acudieron al servicio de videoendoscopías del Centro Médico Alta Tecnología Hernando Dionisio Amaya Benavides de Tucupita en Venezuela, en el periodo 2010-2013. Material y métodos: se realizó un studio descriptivo de corte transversal. Se revisaron 1972 expedientes de pacientes mayores de 15 años, procedentes de instituciones médicas de Barrio Adentro, estatales y privadas, que acudieron al servicio de videoendoscopía del Centro Médico de Alta Tecnología Hernando Dionisio Amaya Benavides de Tucupita, en el periodo 2010-2013. Se estudiaron variables demográficas y clínicas. Resultados: la morbilidad por úlceras pépticas resultó de 9,83%, diagnosticado en 105 pacientes, con mayor frecuencia en el sexo masculino en edades comprendidas entre 45 y 54 años. La principal procedencia en el caso de las úlceras gástricas es de los consultorios médicos populares (CMP), presente en 36 pacientes; en el caso de las duodenales, los procedentes de servicios estatales. La porción más afectada por úlceras gástricas en estómago fue el antro, con 110 úlceras diagnosticadas (94%) y en el duodeno, cara anterior del bulbo, con 51 úlceras de las registradas en esta porción (50%). Conclusiones: la úlcera gástrica es más frecuente que la duodenal, la epigastralgia constituyó el síntoma principal que motivó el estudio en los pacientes ulcerosos. La labor de enfermería contribuye a la realización efectiva en el servicio de videoendoscopía.

Peptic ulcer is an injury to the gastrointestinal mucosa (stomach and duodenum) extending beyond the muscularis mucosae and which remains as a result of the activity of acid secretion in the gastric juice. Objetive: To describe the epidemiological and clinical characteristics of gastric and duodenal ulcers in patients who attended the service videoendoscopias Medical Center of High Technology Dionisio Hernando Amaya Benavides Tucupita in Venezuela, in the 2010 period features-2013. Material and methods: Came on descriptive cross-sectional study. 1972 records of patients older than 15 years, from Barrio Adentro medical institutions, state and private, who atttended the service of High Technology videoendoscopy Dionisio Hernando Amaya Benavides Tucupita in 2010-2013 Medical Center were reviewed. Demographic and clinical variables were studied. Results: Peptic ulcer morbidity was 9.83%, diagnosed in 105 patients, most often in men aged between 45 and 54 years. The main origin in the case of gastric ulcers is popular medical practices (CMP), present in 36 patients; in case of duodenal, those from government services. The most affected by gastric ulcers in stomach antrum portion was with 110 diahgnosticadas ulcers (94%) and in the duodenum, anterior bulb with 51 ulcers recorded in this portion (50%). Conclusions: Gastric ulcer is more frequent than duodenal, epigastric pain was the main symptom that motivated the study ulcer patients. The nursing work contributes to the effective realization of videoendoscopy service.

Analyse des habitudes alimentaires des patients souffrant d'ulcère gastro-duodénal en consultation à l'Hôpital National de Niamey

Il a été procédé par une étude du type descriptive prospective du 1er novembre 2014 au 31 décembre 2014 sur l'analyse des habitudes alimentaires des personnes souffrant d'ulcère gastro-duodénal. Les objectifs de cette étude étaient de dégager les habitudes alimentaires des malades ulcéreux, les facteurs favorisant le développement de l'ulcère liés à l'habitude de vie et aux services de santé. L'ulcère gastro-duodénal connait depuis quelques années une fréquence importante parmi les maladies digestives et le nombre de cas de cette pathologie est en augmentation durant ces trois (3) dernières années au Niger (données S.N.I.S). Les facteurs de risque de la maladie ulcéreuse sont liés aux conditions hygiéno-diététiques des personnes, au stress et à l'infection d'Helicobacter pylori. Dans notre population, les conditions hygiéno-diététiques acceptables ne sont pas assurées. Aucune étude sur les ulcères gastro-duodénaux n'a été faite depuis 1985 au Niger, sauf en 2007 par Mahaman Issiakou c'est compte tenu de ces raisons que nous avons choisi de mener cette étude. L'étude a porté sur un échantillon de 90 malades ulcéreux sans limite d'âge ayant effectués l'examen de fibroscopie et 10 agents de santé. Les techniques de collecte de données utilisées étaient l'entretien avec les malades ulcéreux et l'administration du questionnaire aux agents de santé. Des résultats de cette étude, il ressort que les femmes sont plus touchées que les hommes avec 66,66 % des patients ulcéreux de sexe féminin et 33, 34 % de sexe masculin. 77,77% de nos malades ulcéreux sont des consommateurs d'excitants et que ces excitants constituent un facteur d'agression de la couche protectrice de la muqueuse. 17% de ces patients prennent la cola. Les excitants sont des facteurs de risque de la maladie ulcéreuse. Plus de la moitié des ulcéreux consomment des Antiinflammatoires Non Stéroïdiens (A.I.N.S), et ils font aussi recours au traitement traditionnel en cas des maladies. 77% des patients ont entendu parler de l'ulcère, c'est donc une maladie connue. Ces ulcéreux consomment des repas épicés, consomment des aliments aigres et en mangent des aliments graissés. Nos patients mangent des aliments favorisant l'apparition de l'ulcère. La majorité de nos ulcéreux sont stressés. Plus de la moitié consultent dans les formations sanitaires plus d'un an. Nos malades ont des manifestations typiques ulcéreuses. L'épigastralgie est plus fréquente parmi les signes des manifestations cliniques d'ulcère. 8 malades ont eu à faire leur contrôle durant notre étude ; parmi eux, 77,77% étaient satisfaits de la prise en charge. L'ulcère duodénal domine sur l'ulcère gastrique. Leur rapport est 2,77 à l'avantage de l'ulcère duodénal. Néanmoins, l'ulcère gastrique est plus fréquent chez la femme que chez l'homme avec un rapport de 1,08. Pour prévenir l'ulcère, nous formulons quelques recommandations : -Mener une politique de sensibilisation de la population sur les dangers de la prise excessive de certains excitants et sur la nécessité d'une consultation médicale le plus tôt possible en cas de manifestation clinique ulcéreuse. -Former les spécialistes en matière de gastro-entérologie qui assureront la bonne fonctionnalité du service. -Faire un traitement précoce de l'ulcère par l'éradication d'Hélicobacter Pylori qui est un facteur très important de l'ulcère. -Equiper le service de la médecine B3 par une nouvelle fibroscopie pour rendre plus accessibles les services à la population, et réparer l'ancienne

Does Dual Antiplatelet Therapy Increase the Risk of Peptic Ulcer Disease? / 대한소화기학회지

No abstract available.

Clinical Impact of Dual Antiplatelet Therapy on Peptic Ulcer Disease / 대한소화기학회지

BACKGROUND/AIMS: Increased incidence of coronary artery disease has led to the increased use of dual antiplatelet therapy composed of aspirin and clopidogrel. We investigated the incidence of gastrointestinal complications in patients who received single or dual antiplatelet therapy and analyzed their clinical characteristics in order to predict the prognostic factors. METHODS: Between January 2009 and December 2011, we retrospectively reviewed the medical records of patients who underwent coronary angiography at Chung-Ang University Hospital (Seoul, Korea). One hundred and ninety-four patients were classified into two groups: aspirin alone group and dual antiplatelet group. Clinical characteristics, past medical history, and presence of peptic ulcer were analyzed. RESULTS: During the follow-up period, 11 patients had duodenal ulcer; the event rate was 2.02% in the aspirin alone group and 9.47% in the dual antiplatelet group (hazard ratio [HR] 5.24, 95% CI 1.03-26.55, p<0.05). There was no significant difference in the rate of significant upper gastrointestinal bleeding: 0% vs. 4.2% (p=0.78). In patients who received proton pump inhibitor (PPI), 24 patients had gastric ulcer; the event rate was significantly different between the two groups: 4.87% vs. 22.98% (HR 3.40, 95% CI 1.02-11.27, p<0.05). CONCLUSIONS: Dual antiplatelet groups had a higher incidence of duodenal ulcers without significant bleeding compared with the aspirin alone group. In patients who received PPI, the dual antiplatelet therapy group had a higher incidence of gastric ulcers without significant bleeding compared with the aspirin alone group. Therefore, physicians must pay attention to high risk groups who receive dual antiplatelet therapy and aggressive diagnostic endoscopy should also be considered.

Current Status and Clinical Impact of Pediatric Endoscopy in Korea / 대한소화기학회지

BACKGROUND/AIMS: In pediatrics, endoscopic examination has become a common procedure for evaluation of gastrointestinal presentations. However, there are limited data on pediatric endoscopy in Korea. The aim of this study was to analyze the current status and clinical impacts of endoscopic examination in children and adolescents. METHODS: We retrospectively reviewed the medical records of outpatients who visited the tertiary hospital. Patients under 18 years of age who underwent endoscopy were included. Endoscopic findings were classified as specific and normal based on gross findings. Specific endoscopic findings were reflux esophagitis, peptic ulcers, and Mallory-Weiss tear. Other findings included acute gastritis classified according to the updated Sydney system. RESULTS: In 722 of 330,350 patients (0.2%), endoscopic examination (554 esophagogastroduodenoscopies [EGDs], 121 colonoscopies, 47 sigmoidoscopies) was performed between January 2008 and January 2013. In EGD, abdominal pain was the most frequent presentation (64.1%). The most common diagnosis was gastritis (53.2%), followed by reflux esophagitis. The frequency of peptic ulcer disease was 12.8%. Frequent symptoms leading to colonoscopic examination were abdominal pain, diarrhea, and hematochezia. In colonoscopy, a negative result was more likely in children younger than 7 years old. After the procedure, the diagnostic yield of EGD and colonoscopy was 88.1% and 45.8%, respectively, and the rate of change in management was 67.1%. CONCLUSIONS: In pediatrics, endoscopic examination was useful for the choice of therapeutic strategy and it would be a standard method for evaluation of gastrointestinal presentation.

Antibiotic Resistance in Helicobacter pylori Strains and its Effect on H. pylori Eradication Rates in a Single Center in Korea

BACKGROUND: Clarithromycin, amoxicillin, metronidazole, tetracycline, and levofloxacin have been commonly used for the eradication of Helicobacter pylori. We compared the change in antibiotic resistance of H. pylori strains during two separate periods and investigated the effect of antibiotic resistance on H. pylori eradication. METHODS: H. pylori strains were isolated from 71 patients between 2009 and 2010 and from 94 patients between 2011 and 2012. The distribution of minimal inhibitory concentration (MIC) of 5 antibiotics was assessed using the agar dilution method, and H. pylori eradication based on the antimicrobial susceptibility of the isolates was investigated retrospectively. RESULTS: Antibiotic resistance rate against clarithromycin, amoxicillin, tetracycline, metronidazole, and levofloxacin for the 2009-2010 isolates were 7.0% (5/71), 2.8% (2/71), 0% (0/71), 45.1% (32/71), and 26.8% (19/71), respectively, and for the 2011-2012 isolates were 16.0% (15/94), 2.1% (2/94), 0% (0/94), 56.3% (53/94), and 22.3% (21/94), respectively. Multi-drug resistance for 2 or more antibiotics increased slightly from 16.9% (12/71) in the 2009-2010 isolates to 23.4% (22/94) in the 2011-2012 isolates. In follow-up testing of 66 patients, first-line treatment successfully eradicated H. pylori in 50 patients (75.8%) and failed in 4 of 7 patients (57.1%) in a clarithromycin-resistant and amoxicillin-susceptible group. CONCLUSIONS: We observed an increase in resistance to clarithromycin and an overall increase in multi-drug resistance during the 2 study periods. The effectiveness of the eradication regimen was low with combinations of clarithromycin and amoxicillin, particularly in the clarithromycin-resistant group. Thus, eradication of H. pylori depends upon periodic monitoring of antimicrobial susceptibility.

Association between Dyspepsia and Upper Endoscopic Findings / 대한소화기학회지

BACKGROUND/AIMS: We aimed to estimate the proportion of significant endoscopic findings and their association with dyspeptic symptoms and to evaluate the predictors for significant endoscopic findings. METHODS: Total of 3,872 subjects (58.3% men, mean age 43.6+/-9.3 years) who had undergone endoscopy were enrolled at the health promotion center. Each subject completed validated questionnaires, including data on gastrointestinal symptoms, socio-demographic history and medical history. Significant endoscopic findings were included peptic ulcer disease, reflux esophagitis, gastric cancer, Barrett's esophagus and gastro-duodenal erosions. Multiple logistic regression models were used to assess the predictors for significant endoscopic findings. RESULTS: The proportion of significant endoscopic findings was 39.1%. There was no significant difference of endoscopic findings between the dyspepsia and asymptomatic group (41.0% vs. 37.4%, p>0.05). There was no difference of the incidence of reflux esophagitis or peptic ulcer between subjects with and without dyspepsia. Peptic ulcer was more frequently present in subjects with reflux symptoms than asymptomatic subjects (12.3% vs. 9.0%, p=0.03). Male gender (odds ratio [OR], 3.91; 95% confidence interval [CI], 3.18-4.81) increased the risk for having endoscopic abnormality and having symptoms of functional dyspepsia according to Rome III criteria (OR, 0.75; 95% CI, 0.57-0.97) significantly decreased this risk. CONCLUSIONS: About 40% of subjects with dyspepsia had abnormal endoscopic findings, and the dyspepsia symptoms may not predict the significant endoscopic findings. Diagnostic criteria of functional dyspepsia by Rome III may be useful to predict not having significant upper endoscopic findings.

Clinical Characteristics of Patients Diagnosed as Peptic Ulcer Disease in the Third Referral Center in 2007 / 대한소화기학회지

BACKGROUND/AIMS: In spite of the improvement of medical treatment for the peptic ulcer disease (PUD), PUD is still one of the common upper gastrointestinal diseases. The purpose of this study was to evaluate the risk factors and general characteristics of Korean patients diagnosed as PUD at a single third referral center. METHODS: A total of 310 patients, diagnosed as PUD through endoscopy during one year of 2007 at Seoul National University Bundang Hospital were, retrospectively, evaluated regarding age, gender, Helicobacter pylori (H. pylori) positivity, clinical manifestations, comorbidities and medications. In addition, PUD was analyzed in the aspect of ulcer location, type of visit, gastrointestinal bleeding, and age. RESULTS: The mean age was 61.5 years old (48.1% over 65) and 208 (66.7%) patients were men. The rate of H. pylori infection was 47.8%, and any ulcerogenic medication history such as antiplatelet agents and NSAIDs was found to be 21.0% (65 patients). The rate of idiopathic peptic ulcer without evidence of H. pylori and NSAIDs was found to be 40.6% (126 patients). Among 310 PUD patients, bleeding symptoms such as melena, hematemesis and hematochezia occurred in 110 patients (35.5%). CONCLUSIONS: PUD was more prevalent in the elderly patients and frequently associated with bleeding. Substantial proportion of PUD patients had neither H. pylori infection nor history of ulcerogenic medications, suggesting of increasing prevalence of idiopathic PUD.

Úlceras gastroduodenais como manifestação clínica de histoplasmose disseminada em paciente com vírus da imunodeficiência humana positivo: relato de caso / Progressive disseminated histoplasmosis presenting as gastroduodenal ulcers in a human immunodeficiency virus patient: case report

JUSTIFICATIVA E OBJETIVOS: A histoplasmose é uma doença fúngica causada pelo Histoplasma capsulatum. É rara em imunocompetentes;no entanto, em pacientes imunossuprimidos, a infecção ocorre de forma disseminada e grave, podendo acometer vários órgãos, incluindo o trato gastrintestinal. O objetivo deste estudo foi relatar o caso de uma apresentação incomum de infecção pelo H. capsulatum, alertando os clínicos quanto à inclusão da histoplasmose no diagnóstico diferencial de úlceras gastrintestinais, principalmente no paciente imunocomprometido. RELATO DO CASO: Paciente do sexo masculino, 45 anos,portador de síndrome da imunodeficiência adquirida (SIDA),com perda de peso, febre, sudorese noturna, adenomegalias cervicais e sangramento gastrintestinal. A radiografia de tórax mostrou infiltrado intersticial bilateral difuso, e a tomografia computadorizada (TC) de abdômen mostrou hepatomegalia e adenomegalias intra-abdominais. Na endoscopia digestiva alta foram encontradas úlceras no estômago e duodeno. O exame anatomopatológico das lesões foi compatível com histoplasmose do trato gastrintestinal. CONCLUSÃO: É de extrema importância o diagnóstico diferencial de úlceras gastrintestinais, principalmente em pacientes imunossuprimidos, uma vez que diversas doenças que assim se manifestam se não tratadas adequadamente, têm evolução fatal.

BACKGROUND AND OBJECTIVES: Histoplasmosis is afungal disease caused by Histoplasma capsulatum. It rarely occurs in immunocompetent individuals; however, in immunocompromised patients, the infection is usually severe and disseminated. Many organs can be affected, including the gastrointestinal tract.The objective of this study is to report an uncommon presentation of histoplasmosis, showing that the differential diagnosis of gastrointestinal ulcers is of great importance, particularly in the immunocompromised patient. CASE REPORT: Male patient, 45-year-old, immunodeficiency virus human-positive, was admitted to the hospital presenting with weight loss, night sweats, fever, cervical adenomegalies and gastrointestinal bleeding. Chest radiography showed diffuse interstitial pulmonary infiltrates bilaterally; computerized tomography of the abdomen showed hepatomegaly and intraabdominal adenomegalies. Upper gastrointestinal endoscopy revealed gastric and duodenal ulcers. The pathologic examination of the ulcerswas consistent with gastrointestinal histoplasmosis. CONCLUSION: Reassures the need for the differential diagnosis of gastrointestinal ulcers, particularly in immunosuppressed patients, since many diseases that present this way, have fatal outcomeif not treated properly.

Proinflammatory cytokines and thrombomodulin in patients with peptic ulcer disease and gastric cancer, infected with Helicobacter pylori.

Backgrounds: Helicobacter pylori infect more than half of the global population. It is suggested to be related with gastritis, peptic ulcer disease (PUD), and gastric cancer. Aims: The aim of this present study was to evaluate proinflammatory cytokines including interleukin 1, 6, 8, 10, and thrombomodulin in H. pylori-infected patients with PUD and gastric cancer. Patients: This cross-sectional study was conducted in Taleghani Hospital on 111 patients with H. pylori infection. Materials and Methods: Patients were divided into three groups of PUD, cancer, and control (normal on endoscopy), according to the results of endoscopy. The serum levels of interleukins 1, 6, 8, and 10 and thrombomodulin was determined using enzyme-linked immunosorbent assay (ELISA) technique. H. pylori infection was diagnosed by histological examination of the endoscopic biopsy. Results: One hundred eleven patients were included in the study; 30 as PUD group, 30 as gastric cancer group, and 51 as controls. There was no significant difference between the means of IL-1 and IL-10 levels among the three groups (P = 0.744 and 0.383, respectively). IL-6, IL-8, and thrombomodulin levels were found to be statically different among the three groups (P < 0.05). The level of IL-6, IL-8, and thrombomodulin in cancer group was significantly higher than PUD and control groups (P < 0.05). Conclusion: There is a significant association between H. pylori infection and serum IL-6, IL-8, and thrombomodulin but such relation is not present between H. pylori and IL-1 and IL-10. Immunity response (IL-6, IL-8 and thrombomodulin) is more severe in cancer patient than PUD.

Diagnóstico tardio da imunodeficiência comum variável / Late diagnosis of common variable immunodeficiency

A imunodeficiência comum variável (ICV) é uma doença primária do sistema imunológico associada a infecções recorrentes, principalmente no trato respiratório, fenômenos autoimunes e neoplasias. Sua incidência é relativamente baixa, mas é considerada entre as imunodeficiências primárias sintomáticas a mais comum; mesmo assim o atraso no seu diagnóstico costuma ser muito frequente. Os autores apresentam um caso de um paciente com diagnóstico prévio de anemia perniciosa que apresentava infecções respiratórias de repetição quando o diagnóstico de ICV foi suspeitado

Common variable immunodeficiency (CVID) is a primary disease of the immune system, associated with recurrent infections, mainly in the respiratory tract, autoimmune phenomena and malignancies. Although its incidence is relatively low, it is considered the most common among symptomatic primary immunodeficiencies. Still, the delay in diagnosis is very frequent. The authors present a case of a patient with previous diagnosis of pernicious anemia who presented with recurrent respiratory infections when the diagnosis of CVID was suspected
