Hemorragia del tracto digestivo superior, enfoque para el médico general / Upper digestive tract bleeding, approach for the general Practitioner / Hemorragia do trato digestivo superior, enfoque para o médico geral

La hemorragia del tracto digestivo superior (HTDS) es el sangrado originado por encima del ángulo de Treitz. A pesar del aumento en las estrategias de prevención, del incremento en los tratamientos con Inhibidor de bomba de protones (IBP) y de la intervención endoscópica temprana, esta patología sigue siendo una causa frecuente de consulta a urgencias, con una morbimortalidad no despreciable y alta carga para el sistema de salud. Esta revisión se enfoca en la HTDS de causa diferente a las varices. La principal causante de esta entidad es la enfermedad ácido-péptica, que es consecuencia del gran consumo de antiinflamatorios no esteroideos (AINES) y de la infección por Helicobacter Pylori. Otras causas son el síndrome de Mallory Weiss, la esofagitis erosiva, las malformaciones arteriovenosas y la malignidad.

Upper gastrointestinal bleeding (UGIB) refers to any bleeding originating above the angle of Treitz. Despite an increase in prevention strategies, proton pump inhibitor (PPI) therapy and early endoscopic intervention, this pathology continues to be an important cause of admission to the emergency department for gastrointestinal causes, having a pretty high morbidity and mortality in addition to a high burden on the health system. This review focuses on non-variceal UGIB. The main cause of this entity being peptic acid disease, due to great consumption of NSAIDs and Helicobacter Pylori infection. Other causes are Mallory Weiss syndrome, erosive esophagitis, arteriovenous malformations, and malignancy.

Analysis of the relationship between high altitude polycythemia and peptic ulcer bleeding / 北京大学学报(医学版)

OBJECTIVE@#To explore the relationship between high altitude polycythemia (HAPC) and peptic ulcer bleeding, in order to provide the evidence for the clinical diagnosis and treatment of peptic ulcer disease in Tibet of China.@*METHODS@#A retrospective case-control study was conducted. Patients who hospitalized in the Department of Gastroenterology with the diagnosis of peptic ulcer bleeding from January 1, 2015 to April 30, 2021 in Tibet Autonomous Region People's Hospital were enrolled in the case group, and patients who hospitalized in the Department of Urology without tumor and without the history of peptic ulcer and gastrointestinal bleeding during the same period were selected as the control group. In the study, 1 ∶ 1 case matching was conducted between the two groups according to the gender, age (±2 years), ethnic group (Tibetan, Han), and the residence altitude level (grouped by < 4 000 m or ≥4 000 m), and 393 cases were included in the case group and the control group respectively. All the patients had lived in Tibet with the altitude >2 500 m for more than 1 year, and with age ≥ 18 years. The risk factors of peptic ulcer bleeding (place of residence, smoking, alcohol, the use of NSAIDs/anticoagulants, and combined with chronic diseases, such as HAPC, hypertension, diabetes mellitus, heart disease, hyperlipidemia, cerebrovascular disease, chronic lung disease, joint disease) were analyzed and compared between the two groups.@*RESULTS@#There were 28 (7.1%) patients with HAPC in the case group, and 5 (1.3%) in the control group. The incidence of HAPC in the case group was significantly higher than those in the control group, P < 0.001, and the OR value was 5.953. Multivariate Logistic regression analysis showed that HAPC (OR=5.270, 95%CI: 1.806-15.380), living in cities and towns (OR=2.369, 95%CI: 1.559-3.602), alcohol (OR=3.238, 95%CI: 1.973-5.317) and the use of NSAIDs/anticoagulants (OR=20.584, 95%CI: 2.639-160.545) were the independent risk factors for peptic ulcer bleeding in Tibet. After adjusting for the possible confounding factors, such as living in cities and towns, alcohol, and the use of NSAIDs/anticoagulants, HAPC was associated with an increased risk of peptic ulcer bleeding in Tibet, and the OR value was 5.270.@*CONCLUSION@#HAPC was associated with a significantly increased risk of peptic ulcer bleeding in Tibet. Patients with HAPC and peptic ulcer should be diagnosed and treated actively, in order to avoid gastrointestinal bleeding and other serious complications.

Sero-prevalence of and risk factors associated with Helicobacter pylori infections among individuals with peptic ulcer in Owerri, Imo State, Nigeria during 2020-2021

Background: Helicobacter pylori, which is a causative agent of chronic gastritis, duodenal ulcer and gastric cancer, presently affects approximately one half of the world population. This study was conducted to assess the epidemiology and risk factors for acquisition of H. pylori among individuals with and without peptic ulcer symptoms in Owerri, Nigeria, in order to provide baseline data and create awareness for effective management and prevention of infection caused by this pathogen. Methodology: A total of 384 participants, symptomatic and asymptomatic for peptic ulcer, were recruited from the three Local Government Areas (LGAs) of Owerri, Imo State, Nigeria. The symptomatic participants were randomly recruited among patients attending outpatient clinics with symptoms of peptic ulcer disease at the Federal Medical Center Owerri, general hospitals and primary healthcare centers across Owerri LGAs, while asymptomatic patients were recruited from the community. Information on socio-demographic characteristics of each participant and potential risk factors were collected with a pre-tested structured questionnaire. Blood samples were collected for detection of antibodies (IgG) using a one-step H. pylori test device while faecal samples were collected for detection of occult blood (from peptic ulceration) using faecal occult blood (FOB) test. Data were analyzed using SPSS version 25.0 and association of risk factors with H. pylori sero-prevalence was determined by the Chi-square or Fisher Exact test (with Odds ratio). P value < 0.05 was considered statistically significant.Results: The sero-prevalence of H. pylori infection among the study participants was 72.4% (285/384) while the prevalence of ulcer by FOB test was 71.1% (273/384). A total of 78.4% (214/273) of those with ulcers were seropositive for H. pylori while 64.0% (71/111) of those without ulcers were sero-positive for H. pylori (p=0.0045).Factors significantly associated with high sero-prevalence of H. pyloriwere age groups 41-50 (100%), 21-30 (78.4%) and 31-40 (67.6%) years (X 2=66.964, p<0.0001), illiteracy (OR=6.888, p<0.0001), unemployment (OR=2.427, p<0.0001), low social class status (X2=28.423, p=0.0003), drinking of unclean water (OR=5.702, p<0.0001), living in crowded rooms (OR=2.720, p<0.0001), eating food bought from food vendors (OR=3.563, p<0.0001), family history of ulcer (OR=12.623, p<0.0001), habits of eating raw vegetables and unwashed fruits (OR=6.272, p<0.0001), non-regular hand washing practices before meal (OR=2.666, p<0.0001) and presence of ulcer (OR=2.043, p=0.0045). However, smoking (OR=0.7581, p=0.2449) and gender (OR=0.6538, p=0.0796) were not significantly associated with sero-prevalence of H. pylori. Conclusion: There is need for comprehensive strategy including public health education campaign to create awareness on H. pylori, improve personal hygiene and environmental sanitation, provision of safe drinking water by the government to the populace, and discourage indiscriminate and open defecation

Management of Helicobacter pylori among medical doctors working in Khartoum, Sudan 2019: a cross-sectional study

Background: Various international guidelines have been developed regarding Helicobacter pylori (H. pylori) management, as it is infecting more than half of the world's population. Sudan's health system lacks guidelines regarding H. pylori management, leading to a discrepancy in practice. Investigating the current approach could be a step forward in the formulation of a national consensus in the management of H. pylori. Methods: A cross-sectional study was conducted among medical doctors currently working in Khartoum, Sudan. Participants were enrolled from platforms of medical associations through an online questionnaire. The questionnaire was scored out of 25 points, and scoring 13 or above considered a good approach. Data analysis was carried out using Statistical Package for Social Sciences (SPSS). Results: A total of 358 medical doctors participated in the study. The mean (±SD) score was 12.9(±4.5). Those who were using textbooks, campaigns, symposiums or general medical information to their primary Source of knowledge significantly scored higher. The most selected indication for both diagnosis (76.8%) and treatment (67.6%) was an active peptic ulcer. Stool antigen test (SAT) was the most preferred test (70.7%). The majority of respondents selected triple therapy (82.1%) as a first-line regimen. Only 37.7% confirmed the eradication after four weeks of stopping the treatment. They ensure eradication mainly through SAT (29%). Conclusion: A suboptimal approach was noted among medical doctors of Khartoum, Sudan, regarding H. pylori management. Efforts should be invested in forming national guidelines and the implementation of continuous medical education programs.

Formulation, Optimization, in vitro and in-vivo evaluation of levofloxacin hemihydrate Floating Tablets

Abstract The objective of the present investigation was to design, optimize and characterize the gastro retentive floating levofloxacin tablets and perform in-vivo evaluation using radiographic imaging. The floating tablets were prepared by using polymers i.e hydroxy propyl methyl cellulose (HPMC-K4M) and carbopol-940 individually and in combination by nonaquous granulation method. All the Formulations were evaluated for swelling index (S.I), floating behavior and in-vitro drug release kinetics. The compatibility study of levofloxacin with other polymers was investigated by FTIR, DSC, TGA and XRD. Results from FTIR and DSC revealed no chemical interaction amongst the formulation components. The optimized formulation (F11) showed floating lag time (FLT), total floating time (TFT) swelling index (S.I) of 60 sec, >16h and approximately 75 %, respectively. Moreover, F11 showed zero order levofloxacin release in simulated gastric fluid over the period of 6 h. X-ray studies showed that total buoyancy time was able to delay the gastric emptying of levofloxacin floating tablets in rabbits for more than 4 hours. In conclusion the optimized formulation (F11) can be used for the sustained delivery of levofloxacin for the treatment of peptic ulcer.

Eficacia clínica del extracto de Matico (Piper angustifolium) en la evolución de la cicatrización de heridas por estomatitis aftosa recidivante / Clinical efficacy of Matico extract (Piper angustifolium) in the evolution of wound healing due to recurrent aphthous stomatitis

La estomatitis aftosa recurrente (EAR) es un trastorno ulcerativo doloroso cíclico que comúnmente afecta la mucosa oral. Factores locales y sistémicos como trauma, sensibilidad alimentaria, deficiencias nutricionales, condiciones sistémicas y desórdenes inmunológicos están asociados con el desarrollo de la enfermedad. Debido a las similitudes en las características de las úlceras pépticas y las úlceras aftosas orales, parece razonable suponer que Helicobacter pylori podría desempeñar un papel en el desarrollo de la EAR. Las especies de Piper son plantas aromáticas que se utilizan como especias en la cocina, pero sus metabolitos secundarios también han mostrado efectos biológicos sobre la salud humana. El objetivo del presente estudio fue determinar la relación entre H. pylori y EAR y el efecto cicatrizante del extracto Matico sobre las ulceras bucales. Se reclutó a cuarenta sujetos con EAR. Los participantes fueron asignados al azar al grupo de prueba o al grupo de control. El tamaño y número de las úlceras se registraron el día 1 (valor inicial) y el día 30 (valor final). El tamaño de la ulceras, presencia de pseudomembranas y halos eritematosos fueron estadisticamente significativas en relación a la positividad de H. pylori (p <0,05). No hubo diferencias significativas entre la morfología, número y localización de las aftas (p> 0,05). El grupo que recibió el extracto tuvo un porcentaje de mejoría en la reducción del número de aftas del 65% el día final de evaluación en comparación de sólo un 25% del grupo que no recibió el extracto Matico(AU)

Recurrent aphthous stomatitis (RAS) is a cyclic painful ulcerative disorder that commonly affects the oral mucosa. Local and systemic factors such as trauma, food sensitivity, nutritional deficiencies, systemic conditions, immunological disorders and genetic polymorphisms are associated with the development of the disease. Because of similarities in the characteristics of peptic ulcers and oral aphthous ulcers, it seems reasonable to hypothesize that Helicobacter pylori could play a role in the development of RAS. Piper species are aromatic plants used as spices in the kitchen, but their secondary metabolites have also shown biological effects on human health. The aim of the present study was to determine the relationship between H. pylori and RAS and the healing effect of Matico extract on mouth ulcers. Fuorty subjects with RAS were recruited. The participants were randomly allocated to the test group or the control group. The size and number of ulcers were recorded on day 1 (initial value) and day 30 (final value). The size of the ulcers, the presence of pseudomembranes and erythematous halos were statistically significant in relation to the positivity of H. pylori (p <0.05). There were no significant differences between the morphology, number and location of the canker sores (p> 0.05). The group that received the extract had a percentage improvement in the reduction of the number of canker sores of 65% on the final day of evaluation compared to only 25% of the group that did not receive the Matico extract(AU)

El hallazgo endoscópico fue mayor para las formas no erosivas, y de acuerdo a la histopatología la gastritis no atrófica antral moderada fue la más frecuente(AU)

Gastritis is a disease with high morbidity worldwide, the main risk factor is Helicobacter pylori infection. Objective: To describe the clinical, histopathological and endoscopic characteristics in a population with chronic gastritis. Material and methods: An observational, descriptive, retrospective study was carried out, including 49 patients who attended the outpatient consultation of the gastroenterology area, aged 18 to 65 years, who underwent a histopathological and endoscopic study in the Gastroenterology Service at the Quevedo General Hospital, Los Ríos-Ecuador, during September 2017 - September 2018. Results: A predominance of the male gender was observed (65%); In people over 40 years of age (55%), epigastralgia and the sensation of heartburn, 39% and 35% spectively, were the most frequent symptoms, the positivity for Helicobacter pylori, reached 86%, and the non-erosive lesion 73 %, there was a greater presence of the non-atrophic form (84%) over the atrophic one. Conclusions: Chronic gastritis predominated in the age group over 40 years of age and male, the most prevalent risk factors being Helicobacter pylori infection and those associated with the consumption of non-steroidal anti-inflammatory drugs, poor diet, alcohol and tobacco. symptoms such as epigastric pain and the sensation of heartburn were the most frequent. The endoscopic finding was greater for non-erosive forms, and according to histopathology, moderate antral non-atrophic gastritis was the most frequent(AU)

Evolución del tratamiento de la Úlcera péptica duodenal / Evolution of duodenal peptic ulcer treatment

Introducción: Como consecuencia del desarrollo del tratamiento médico de la úlcera péptica duodenal, el tratamiento quirúrgico ha disminuido notablemente. Objetivo: El objetivo del estudio es describir la progresión del tratamiento de la úlcera péptica duodenal. Material y Métodos: Estudio descriptivo, de corte, desde finales del siglo XIX hasta la actualidad. Se utilizó el método histórico-lógico y un análisis deductivo-inductivo de múltiples fuentes bibliográficas. Desarrollo: A pesar de ser la úlcera una entidad clínica reconocida desde la antigüedad, los cirujanos la consideraron causada por el ácido, y todos los esfuerzos fueron concentrados en eliminar el ácido por medio de una operación. A partir de 1881, se comenzaron a conocer las complicaciones. En la década de los años 30 del pasado siglo, se tratan las complicaciones y también la enfermedad. Desde 1940, además, se conserva el funcionamiento digestivo y aparecen las tres formas básicas de vagotomía. En la década de 1970, se desarrollaron novedosas técnicas quirúrgicas, la endoscopía, la radiología intervencionista y la cirugía mínimamente invasiva. Sin embargo, el tratamiento médico llegó con los poderosos supresores del ácido y el descubrimiento del Helicobacter pylori. Nuevamente la cirugía ha quedado relegada a tratar las úlceras refractarias y las complicadas. Conclusiones: El tratamiento médico, por medio de la terapia anti-Helicobacter asociada a potentes inhibidores de la secreción gástrica ha conseguido su curación; sin embargo, la cirugía todavía tiene un importante papel en el tratamiento de la úlcera refractaria o complicada(AU)

Introduction: Surgical treatment of duodenal peptic ulcer has notably decreased as a consequence of the development of medical treatment. Objective: The objective of this study is to describe the advances in the treatment of duodenal peptic ulcer. Material and Methods: A descriptive study was conducted from the end of the 19th century to the present. The historical-logical method and a deductive-inductive analysis of multiple bibliographic sources were used. Development: Despite ulcer has been recognized as a clinical entity since ancient times, surgeons considered that it is caused by acid; therefore, all efforts were concentrated on removing the acid through an operation. From 1881 on, complications began to be treated. In the decade of the 30s of the last century, complications and the disease were treated. Since 1940, the digestive function has also been preserved and the three basic forms of vagotomy appeared. In the 1970s, novel surgical techniques such as endoscopy, interventional radiology, and minimally invasive surgery were developed. However, powerful acid suppressants as well as the discovery of Helicobacter pylori were taken into consideration for medical treatment. Once again, surgery was relegated to the treatment of refractory ulcers and complicated ulcers. Conclusions: Medical treatment with anti-Helicobacter therapy associated with potent inhibitors of gastric acid secretion has managed its healing; however, surgery still plays an important role in the treatment of refractory or complicated ulcer(AU)

Perfil epidemiológico de pacientes com hemorragia gastrointestinal alta não varicosa decorrente de doença péptica em um hospital brasileiro terciário de referência / Epidemiological profile of patients with non-variceal upper gastrointestinal bleeding secondary to peptic disease in a tertiary referral brazilian hospital

ABSTRACT BACKGROUND: Non-variceal upper gastrointestinal bleeding (NVUGIB) secondary to peptic ulcer disease is a medical digestive emergency and could be one of the most serious adverse drug reactions. OBJECTIVE: To identify the frequency of diagnosis of NVUGIB secondary to peptic ulcer disease. METHODS: Prospective and epidemiological study conducted in a tertiary referral Brazilian hospital, from July 2016 to December 2019. Upper gastrointestinal endoscopies (UGE) reports were evaluated daily. The diagnosis of NVUGIB secondary to peptic ulcer disease was defined through endoscopic findings of peptic ulcer and erosive gastric lesions, and clinical symptoms. The frequency of diagnosis of NVUGIB secondary to peptic ulcer disease was estimated through the ratio between the number of patients diagnosed and the number of patients underwent UGE in the same period. RESULTS: A total of 2,779 endoscopic reports (2,503 patients) were evaluated, and 178 patients were eligible. The total frequency of diagnosis of NVUGIB secondary to peptic ulcer disease was 7.1%. The annual frequency of diagnosis between 2017 and 2019 ranged from 9.3% to 5.7%. Most patients were men (72.8%); self-declared white (71.8%); older people (56.7%); and, had no familiar or personal history of gastrointestinal diseases (60.1%). 90% of the patients had a peptic ulcer and melena (62.8%). Patients made chronic use of low-dose aspirin (29.3%), other antiplatelet agents (21.9%) and, oral anticoagulants (11.2%); and non-steroidal anti-inflammatories use in the week a prior to the onset of clinical symptoms (25.8%). CONCLUSION: Seven in every 100 patients admitted and underwent UGE in a tertiary hospital were diagnosed with NVUGIB secondary to peptic ulcer disease.

OBJETIVO: Estimar a frequência de HDANV secundária à doença péptica. MÉTODOS: Estudo prospectivo e epidemiológico realizado em um hospital brasileiro terciário de referência, no período de julho de 2016 a dezembro de 2019. Os laudos de endoscopia gastrointestinal alta foram avaliados diariamente. O diagnóstico de HDANV secundária para úlcera péptica foi definido por achados endoscópicos de úlcera péptica e lesões gástricas erosivas e sintomas clínicos. A frequência de diagnóstico de HDANV secundária à úlcera péptica foi estimada por meio da razão entre o número de pacientes diagnosticados e o número de pacientes submetidos à endoscopia gastrointestinal alta no mesmo período. RESULTADOS: Um total de 2.779 laudos endoscópicos (2.503 pacientes) foram avaliados e 178 pacientes foram elegíveis. A frequência total de diagnóstico de HDANV secundária à úlcera péptica foi de 7,1%. A frequência anual de diagnósticos entre 2017 e 2019 variou de 9,3% a 5,7%. A maioria dos pacientes era do sexo masculino (72,8%); auto-declarado branco (71,8%); idoso (56,7%); e não possuía histórico familiar ou pessoal de doenças gastrointestinais (60,1%). 90% dos pacientes apresentaram úlcera péptica e melena (62,8%). Os pacientes faziam uso crônico de ácido acetilsalicílico como antiagregante plaquetário (29,3%), outros antiplaquetários (21,9%) e anticoagulantes orais (11,2%); e fizeram uso e uso de anti-inflamatórios não esteroidais na semana anterior ao início dos sintomas clínicos de HDANV (25,8%). CONCLUSÃO: Cerca de sete em cada 100 pacientes admitidos em um hospital terciário e submetidos à endoscopia gastrointestinal alta foram diagnosticados com HDANV secundária à úlcera péptica.

Tratamiento endoscópico de la obstrucción del tracto de salida gástrico de origen péptico-cicatricial en un niño de 4 años / Endoscopic treatment of cicatricial pyloric stenosis of peptic origin in a 4-year-old boy

La obstrucción de la salida gástrica es una afección infrecuente en la edad pediátrica. Tradicionalmente, la cirugía ha sido el modo de tratamiento estándar, pero está asociada a mayor morbimortalidad. El tratamiento endoscópico ha surgido como una alternativa al tratamiento convencional. Presentamos el caso de un paciente de 4 años con estenosis prepilórica secundaria a enfermedad ulceropéptica. El cuadro clínico empezó con vómitos y dolor abdominal de 2 meses de evolución. Frente a la falta de respuesta al tratamiento médico y a la dilatación endoscópica con balón, se realizaron incisiones radiadas con electrocauterio e inyecciones de esteroides. La terapéutica endoscópica con balón debería ser el primer gesto terapéutico en este tipo de estenosis refractarias al tratamiento médico

Gastric outlet obstruction is an uncommon condition in children. Traditionally, surgery has been the standard mode of treatment, but it is associated with higher morbidity and mortality. Endoscopic treatment has emerged as an alternative to conventional treatment. We present the case of a 4-year-old patient with refractory prepyloric stenosis secondary to peptic ulcer disease. The picture begins with vomiting and abdominal pain of 2 months of evolution. Pre-pyloric stenosis was confirmed. Faced with the lack of response to medical treatment and balloon dilation, radiated incisions were made with electrocautery and steroid injections. When medical treatment is not sufficient, endoscopic balloon therapy should be the first therapeutic gesture in this type of stenosis; given its refractoriness, we believe it is important to highlight the usefulness of endoscopic treatment, which could prevent surgery and associated morbidity and mortality.

Mechanism of Magnoliae Officinalis Cortex in treatment of peptic ulcer based on network pharmacology and molecular docking / 中国中药杂志

Magnoliae Officinalis Cortex(Houpo) can treat peptic ulcer disease(PUD), the mechanism of which remains unclear. In this study, network pharmacology and molecular docking were employed to predict the mechanism of Houpo in the treatment of PUD. Through literature review and TCMSP screening, 15 main active ingredients were obtained. The SwissTargetPrediction database was used to predict the potential targets of the ingredients, and Therapeutic Target Database(TTD), DrugBank, and Human Phenotype Ontology(HPO) to screen the disease-related targets. A total of 49 potential targets were obtained by the intersection of active ingre-dients-related targets and disease-related targets. Cytoscape 3.6.1 was employed to construct the protein-protein interaction network for the targets with high confidence(score>0.700) screened out by STRING. The DAVID database was used for GO and KEGG pathway enrichment of potential targets. GO enrichment analysis showed that the treatment mechanism was mostly related to nuclear receptor activity, ligand-activated transcription factor activity, and G protein-coupled acetylcholine receptor activity. KEGG enrichment analysis found that Houpo could regulate material metabolism, endocrine system, p53 signaling pathway, and PPAR signaling pathway. Molecu-lar docking verified that all 15 ingredients had good binding activities with key targets(CHRM1, CHRM2, FABP1, mTOR, and STAT3). The results mean that Houpo can treat PUD by participating in cell metabolism, inhibiting inflammatory cytokines, and regulating cell proliferation and apoptosis.

Five-year Prevalence of Gastrointestinal Diseases and Disorders in Akure South, Nigeria

The burden of gastrointestinal diseases and disorders (GIDD) remains high in Nigeria and varies across regions. This study wa s therefore designed to examine the prevalence of gastrointestinal diseases and disorders over a period of 5-years from January 2014 to December 2018 in Akure South of Ondo state, Nigeria. Descriptive retrospective study was employed and the medical records of all patients diagnosed for GIDD in the two selected health facilities were reviewed within the study period. In total, 12,323 medical records of patients with GIDD were included in this study. The prevalence of GIDD were 44.9% in the year 2014 with the lowest prevalence of 6.7% occurring in the year 2018. Over the 5-years period, lower GIDD cases were 91% compared to upper GIDD that was 9%. Peptic ulcer had the highest prevalence (55%) of lower GIDD followed by gastroenteritis (30%). Hiatal hernia had the highest prevalence (84%) for upper GIDD followed by dyspepsia (11%) and Gastroesophageal reflux disease (5%). Over a 5-year period, the prevalence of gastrointestinal disease and disorders in Akure south in this study shows that lower GIDD is more prevalent in the study area with peptic ulcer as the most predominant GIDD among the study population.

O fator de virulência relacionado ao H. pylori influencia a expressão de quimiocinas CXCL10, CCL17, CCL20, CCL22, e seus receptores por células mononucleares de sangue periféricos de pacientes com úlceras pépticas / The h. pylori-related virulence factor caga influences the expression of chemokines cxcl10, ccl17, ccl20, ccl22, and their receptors by peripheral blood mononuclear cells from peptic ulcer patients

ABSTRACT BACKGROUND: During the Helicobacter pylori (HP) infection, the infiltration of the leukocytes into stomach mucosa is directed by locally produced chemokines that play a decisive role in infection outcome. The CagA is the most potent virulence factor of HP, so that the infection with CagA + strains is associated with more severe complications than infection with CagA - HP. OBJECTIVE: The aim was to determine the expression of chemokines CXCL10, CCL17, CCL20 and CCL22, and their receptors by CagA + HP- and CagA - HP-derived crude extract (HP-CE)-stimulated peripheral blood mononuclear cells (PBMCs) from peptic ulcer (PU) patients. METHODS: The serum and the PBMCs were collected from 20 HP-infected PU patients, 20 HP-infected asymptomatic subjects (HIA) and 20 non-infected healthy subjects (NHS). The PBMCs were cultured in absence of stimulator or with 10 µg CagA + HP crude extract (CagA + CE), 10 µg CagA - HP crude extract (CagA - CE). Chemokines and receptors were measured by ELISA and real time-PCR respectively. RESULTS: In PU patients, the production of chemokines CXCL10, CCL17, CCL20 and CCL22, and the expression of chemokine receptors CXCR3, CCR4 and CCR6 by CagA + CE-induced PBMCs were significantly higher than non-stimulated and CagA - CE stimulated cultures. The CXCL10 production by CagA + CE stimulated PBMCs from HIA subjects was significantly higher than the equal cultures from PU and NHS groups. The CCL17 and the CCL20 production by non-stimulated, CagA + CE stimulated, and CagA - CE stimulated PBMCs from PU subjects were significantly higher than the equal cultures from NHS and HIA groups. The CCL22 production by non-stimulated, CagA + CE stimulated and CagA - CE stimulated PBMCs from NHS group were significantly higher than the equal cultures from HIA and PU groups. The CagA + CE stimulated PBMCs from HIA subjects expressed lower amounts of CCR6 in comparison with CagA + CE stimulated PBMCs from NHS and PU groups. The serum levels CXCL10 and CCL20 in PU and HIA groups were significantly higher than NHS subjects. NHS and HIA groups displayed higher serum levels of CCL22 in comparison with PU patients. CONCLUSION: Results indicated that the CagA status of bacterium influence the expression of chemokines and receptors by HP-CE stimulated PBMCs from PU patients.

RESUMO CONTEXTO: Durante a infecção por Helicobacter pylori (HP), a infiltração dos leucócitos na mucosa estomacal é dirigida por quimiocinas produzidas localmente que desempenham um papel decisivo no resultado da infecção. O CagA é o fator de virulência mais potente do HP, de modo que a infecção com cepas CagA + está associada a complicações mais graves do que a infecção com CagA - HP. OBJETIVO: O objetivo foi determinar a expressão das quimiocinas CXCL10, CCL17, CCL20 e CCL22, e seus receptores por CagA + HP- e CagA - extrato bruto (EB) derivado de HP (HP-EB) de células mononucleares do sangue periférico (CMSP) de pacientes com úlcera péptica (UP). MÉTODOS: O soro e as CMSP foram coletados de 20 pacientes com UP infectados pelo HP, 20 indivíduos assintomáticos infectados pelo HP (AI-HP) e 20 indivíduos saudáveis não infectados pelo HP (NI-HP). As CMSP foram cultivadas na ausência de estimulador ou com extrato bruto CagA + HP de 10 μg (CagA + EB), 10 μg CagA - extrato bruto HP (CagA - EB). Quimiocinas e receptores foram medidos por ELISA e PCR em tempo real, respectivamente. RESULTADOS: Em pacientes com UP a produção de quimiocinas CXCL10, CCL17, CCL20 e CCL22, e a expressão dos receptores de quimiocina CXCR3, CCR4 e CCR6 por CagA + CMSP induzidos pelo EB foram significativamente maiores do que as culturas não estimuladas e CagA - EB estimulados. A produção de CXCL10 por CagA + EB estimulou as CMSP de sujeitos AI-HP em proporção significativamente maior do que as culturas iguais dos grupos UP e NI-HP. A produção de CCL17 e CCL20 por grupos não estimulados, CagA + EB estimulado, e CagA - EB estimulou CMSP de sujeitos com UP e foram significativamente superiores às culturas iguais dos grupos NI-HP e AI-HP. A produção de CCL22 por grupos não estimulados, CagA + EB estimulado e CagA - EB estimulado pelo grupo NI-HP foram significativamente maiores do que as culturas iguais dos grupos AI-HP e PU. O CagA + EB estimulou as CMSP dos sujeitos do AI-HP, expressando menores quantidades de CCR6 em comparação com as CMSP estimuladas pelo CagA + EB de grupos NI-HP e UP. Os níveis sanguíneos de CXCL10 e CCL20 nos grupos UP e AI-HP foram significativamente superiores aos dos sujeitos do NI-HP. Os grupos NI-HP e AI-HP apresentaram níveis sanguíneos mais elevados de CCL22 em comparação com pacientes com UP. CONCLUSÃO: Os resultados indicaram que o estado CagA da bactéria influencia a expressão de quimiocinas e receptores por HP-EB estimulados CMSP de pacientes com UP.

Revisión teórica de los factores de riesgos asociados a hemorragia digestivas altas en pacientes geriátricos / Theoretical review of risk factors associated with high digestive hemorrhage in geriatric patients

La hemorragia digestiva alta aguda (HDAA) es la emergencia gastrointestinal más frecuente. En los ancianos se asocia con tasas de internación, morbilidad y mortalidad más elevadas que en las personas jóvenes, probablemente por la prevalencia más elevada de múltiples comorbilidades, como las enfermedades pulmonares y cardiovasculares. Objetivo: Describir los fundamentos teóricos de los factores de riesgos asociados a hemorragia digestivas altas. Metodología: Documental, descriptiva. Resultados: diversos estudios demuestran que los factores de riesgos asociados a las hemorragias digestivas altas son: la úlcera péptica gastroduodenal y várices esofágicas, complicaciones graves con alto riesgo de mortalidad en pacientes de edades avanzadas, por lo que se debe actuar con rapidez, eficacia y efectividad. Conclusión: la bibliografía consultada revela: que a pesar de los avances de la tecnología y de la farmacología, la tasa de mortalidad global por hemorragia digestiva alta no ha mejorado. Esta realidad se explica por el aumento significativo en la edad de los pacientes que hoy ingresan a los servicios de urgencias con esta complicación. En la HDAA es fundamental intentar identificar y tratar la fuente del sangrado, para lo cual resulta esencial la endoscopia temprana(AU)

Acute upper gastrointestinal bleeding (HDAA) is the most frequent gastrointestinal emergency. In the elderly, it is associated with higher hospitalization, morbidity and mortality rates than in young people, probably due to the higher prevalence of multiple comorbidities, such as pulmonary and cardiovascular diseases. Objective: To describe the theoretical foundations of the risk factors associated with upper gastrointestinal bleeding. Methodology: Documentary, descriptive. Results: various studies show that the risk factors associated with upper gastrointestinal bleeding are, gastroduodenal peptic ulcer and esophageal varices, serious complications with a high risk of mortality in elderly patients, therefore, it is necessary to act quickly, efficiently and effectiveness. Conclusion: the bibliography consulted reveals: that despite advances in technology and pharmacology, the overall mortality rate from upper gastrointestinal bleeding has not improved. This reality is explained by the significant increase in the age of patients who today enter the emergency services with this complication. In HDAA it is essential to try to identify and treat the source of the bleeding, for which early endoscopy is essential(AU)

Carcinoma gástrico: revisión bibliográfica / Gastric Carcinoma: literature review

Resumen El carcinoma gástrico hoy en día es una de las principales causas de mortalidad a nivel mundial por neoplasias y especialmente en países como Costa Rica, que se cataloga como un país de alta incidencia. Existen múltiples factores de riesgo, siendo el primero y más importante la infección por Helicobacter pylori, que desencadena una cascada de diferentes lesiones, iniciando en atrofia gástrica, que puede llegar a finalizar en cáncer invasivo. Existen otros factores que pueden influir en un ambiente pro-carcinogénico tales como fumado, obesidad, la dieta, entre otros. Múltiples naciones han desarrollado diferentes guías de tamizaje para disminuir la mortalidad; sin embargo, en países con alta incidencia sigue siendo el estándar realizar estudios de imagen y endoscopia luego de determinada edad dependiendo de factores de riesgo.

Abstract Gastric carcinoma is nowadays one of the main causes of mortality worldwide due to neoplasms and especially in countries such as Costa Rica, which is classified as a high incidence country. There are multiple risk factors, starting with Helicobacter pylori infection being the most important one; after the infection a cascade with different lesions is triggered, first it begins with gastric atrophy and then eventually lead to an invasive cancer. There are other factors that can influence a pro-carcinogenic environment such as smoking, obesity, diet, among others. Multiple nations have developed different screening guidelines to reduce mortality, however in countries with high incidence it is still the gold-standard to perform imaging and endoscopy studies after a certain age and depending on risk factors.

Adesão a um protocolo de profilaxia de úlcera de estresse em pacientes críticos: estudo de coorte prospectiva / Adherence to a stress ulcer prophylaxis protocol by critically ill patients: a prospective cohort study

RESUMO Objetivo: Avaliar a adesão ao protocolo de profilaxia de úlcera de estresse em pacientes críticos de um hospital universitário terciário. Métodos: Neste estudo de coorte prospectiva, incluímos todos os pacientes adultos admitidos às unidades de terapia intensiva clínica e cirúrgica de um hospital terciário acadêmico. Nosso único critério de exclusão foi a presença de sangramento gastrointestinal alto quando da admissão à unidade de terapia intensiva. Colhemos as variáveis basais e indicações de profilaxia de úlcera de estresse, segundo o protocolo institucional, assim como o uso de profilaxia. Nosso desfecho primário foi a adesão ao protocolo de profilaxia de úlcera de estresse. Os desfechos secundários foram uso apropriado da profilaxia de úlcera de estresse, incidência de sangramento gastrointestinal superior e fatores associados com o uso apropriado da profilaxia de úlcera de estresse. Resultados: Foram incluídos 234 pacientes no período compreendido entre 2 de julho e 31 de julho de 2018. Os pacientes tinham idade de 52 ± 20 anos, sendo 125 (53%) deles cirúrgicos, e o SAPS 3 médio foi de 52 ± 20. No seguimento longitudinal, foram estudados 1.499 pacientes-dias; 1.069 pacientes-dias tiveram indicação de profilaxia de úlcera de estresse, e 777 pacientes-dias tiveram uso profilático (73% de adesão ao protocolo de profilaxia de úlcera de estresse). Dentre os 430 pacientes-dias sem indicações de profilaxia de úlcera de estresse, 242 envolveram profilaxia (56% de uso impróprio de profilaxia de úlcera de estresse). O total de uso apropriado de profilaxia de úlcera de estresse foi de 64%. Fatores associados com prescrição adequada de profilaxia de úlcera de estresse foram ventilação mecânica, com RC 2,13 (IC95% 1,64 - 2,75), e coagulopatia, com RC 2,77 (IC95% 1,66 - 4,60). A incidência de sangramento do trato gastrointestinal superior foi de 12,8%. Conclusão: A adesão ao protocolo de profilaxia de úlcera de estresse foi baixa, e o uso inadequado de profilaxia de úlcera de estresse foi frequente nesta coorte de pacientes críticos.

ABSTRACT Objective: To evaluate adherence to the stress ulcer prophylaxis protocol in critically ill patients at a tertiary university hospital. Methods: In this prospective cohort study, we included all adult patients admitted to the medical and surgical intensive care units of an academic tertiary hospital. Our sole exclusion criterion was upper gastrointestinal bleeding at intensive care unit admission. We collected baseline variables and stress ulcer prophylaxis indications according to the institutional protocol and use of prophylaxis. Our primary outcome was adherence to the stress ulcer prophylaxis protocol. Secondary outcomes were appropriate use of stress ulcer prophylaxis, upper gastrointestinal bleeding incidence and factors associated with appropriate use of stress ulcer prophylaxis. Results: Two hundred thirty-four patients were enrolled from July 2nd through July 31st, 2018. Patients were 52 ± 20 years old, 125 (53%) were surgical patients, and the mean SAPS 3 was 52 ± 20. In the longitudinal follow-up, 1499 patient-days were studied; 1069 patient-days had stress ulcer prophylaxis indications, and 777 patient-days contained prophylaxis use (73% stress ulcer prophylaxis protocol adherence). Of the 430 patient-days without stress ulcer prophylaxis indications, 242 involved prophylaxis (56% inappropriate stress ulcer prophylaxis use). The overall appropriate use of stress ulcer prophylaxis was 64%. Factors associated with proper stress ulcer prophylaxis prescription were mechanical ventilation OR 2.13 (95%CI 1.64 - 2.75) and coagulopathy OR 2.77 (95%CI 1.66 - 4.60). The upper gastrointestinal bleeding incidence was 12.8%. Conclusion: Adherence to the stress ulcer prophylaxis protocol was low and inappropriate use of stress ulcer prophylaxis was frequent in this cohort of critically ill patients.

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).
