RESUMO

Introducción: la infección por Helicobacter pylori y la ingestión de antiinflamatorios no esteroideos (AINEs) constituyen los dos factores de riesgo independientes más importantes involucrados en la etiopatogenia del daño de la mucosa gastroduodenal. Una posible interacción entre ellos que influencie la magnitud de la gastritis crónica antral, es un tema controversial. Objetivo: estimar el comportamiento histopatológico de la gastritis crónica antral por Helicobacter Pylori asociado o no al consumo de antiinflamatorios no esteroideos. Método: estudio caso control, se tomó como universo los 282 pacientes con panendoscopia y biopsia gástrica antral realizadas en el Hospital Vladimir I. Lenin, entre febrero de 2008 e igual mes de 2009. Se seleccionó una muestra de 91 pacientes con diagnóstico histopatológico de gastritis crónica antral por Helicobacter pylori. De ellos, 32 consumidores de AINES (grupo estudio) y 59 no consumidores (grupo control). Resultados: el 81,25 % del grupo estudio presentaron gastritis crónica activa, aunque con predominio en el grupo control (Z=2,085; p<0,05). El 59,37 % del grupo estudio presentó severidad de lesión ligera con una proporción significativamente mayor de severidad de lesión moderada-severa en el control (Z=4,568; p<0,001). La densidad moderada-abundante se observó en 53,13 % del grupo estudio sin diferencia significativa con el control (Z=0,889; P›0,05). Conclusiones: el predominio de la actividad y la severidad de la lesión moderada-severa de la gastritis crónica antral por Helicobacter pylori en los pacientes no consumidores de AINES pudiera deberse a hipotéticas acciones tanto inhibitoria de la actividad inflamatoria como protectora de la mucosa gástrica de los AINES. El consumo de AINES no parece ejercer una influencia significativa sobre la densidad de colonización.


Introduction: Helicobacter pylori infection and nonsteroidal anti-inflammatory drugs (NSAIDs) are two independent risks factors mostly involved in the etio-pathogenesis of gastrointestinal mucosal damage. A possible interaction between them, influencing the magnitude of the chronic antral gastritis, is controversial. Objective: to estimate histopathological aspects of chronic antral gastritis due to Helicobacter pylori, either in association or not with nonsteroidal anti-inflammatory drugs consumption. Method: a case-control study in which the universe was conformed by 282 patients on whom an endoscopic antral biopsy was performed. It took place at Vladimir I. Lenin Hospital, from February 2008 to February 2009. Ninety one patients with histological diagnosis of Helicobacter pylori chronic antral gastritis constituted the sample of the study, 32 of them were non-steroidal anti-inflammatory drugs users (study group), and 59 were not (controls). Results: although 81.25 % in the study group had chronic active gastritis, this was prevalent in controls (Z=2.085; p<0.05). 59.37 % of the study group showed mild severity inflammation, with a statistically significant greater proportion of moderate to severe lesions in controls (Z=4.568; p<0.001). Moderate to high Helicobacter density was observed in 53.13 % of the study group, with no significant differences with respect to controls (Z=0.889; p>0,05). Conclusions: the prevalence of the activity and moderate to severe inflammation in antral chronic gastritis due to Helicobacter pylori in non-consumers of non-steroidal anti-inflammatory drugs might be hypothetically attributed to both the anti-inflammatory action as well as a protective effect of the gastric mucosa exerted by non-steroidal anti-inflammatory drugs in patients taking these drugs. The colonization density does not appear to be significantly influenced by these drugs.

RESUMO

Se efectuó un estudio descriptivo y retrospectivo de 257 ancianos con afecciones gastroduodenales, según resultados clinicoendoscópicos e histológicos, ingresados en las salas de Medicina Interna y Geriatría del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso" de Santiago de Cuba, durante el bienio 2010-2011, con vistas a caracterizarles e identificar los principales diagnósticos en ellos. Entre las entidades gastroduodenales predominaron las enfermedades gástricas; asimismo, preponderaron el sexo masculino, el grupo etario de 70-79 años y la gastritis antral como hallazgo endoscópico. Se demostró que en un número elevado de pacientes estaba infectado por Helicobacter pylori y que la densidad de colonización ligera se distinguió a medida que progresaba la lesión gástrica.


A descriptive and retrospective study of 257 old men with gastric and duodenal disorders, according to clinical endoscopic and histological results who were admitted in the Internal Medicine and Geriatrics Departments of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital in Santiago de Cuba was carried out during the biennium 2010-2011, with the aim of characterizing them and to identify the main diagnosis in them. Among the gastric and duodenal diseases the gastric ones prevailed; also, the male sex, the age group 70-79 years and the antral gastritis as endoscopic finding prevailed. It was demonstrated that a high number of patients were infected by Helicobacter pylori and that the density of slight colonization was distinguished as the gastric lesion progressed.

RESUMO

Chronic inflammation and infection are major risk factors for gastric carcinogenesis in adults. As chronic gastritis is common in Mexican children, diagnosis of Helicobacter pylori and other causes of gastritis are critical for the identification of children who would benefit from closer surveillance. Antral biopsies from 82 Mexican children (mean age, 8.3 ± 4.8 years) with chronic gastritis (36 H pylori+, 46 H pylori-) were examined for gastritis activity, atrophy, intestinal metaplasia (IM), and immunohistochemical expression of gastric carcinogenesis biomarkers caudal type homeobox 2 (CDX2), ephrin type-B receptor 4 (EphB4), matrix metalloproteinase 3 (MMP3), macrophage migration inhibitory factor (MIF), p53, ß-catenin, and E-cadherin. Atrophy was diagnosed in 7 (9%) of 82, and IM, in 5 (6%) of 82 by routine histology, whereas 6 additional children (7%) (3 H pylori+) exhibited aberrant CDX2 expression without IM. Significant positive correlations were seen between EphB4, MMP3, and MIF (P<.0001). Atrophy and follicular pathology were more frequent in H pylori+ biopsies (P<.0001), whereas IM and CDX2 expression showed no significant correlation with H pylori status. Antral biopsies demonstrating atrophy, IM, and/or aberrant CDX2 expression were seen in 21.95% (18/82) of the children, potentially identifying those who would benefit from closer surveillance and preventive dietary strategies. Biomarkers CDX2, EphB4, MMP3, and MIF may be useful in the workup of pediatric gastritis.

RESUMO

Introducción: la gastritis crónica antral por Helicobacter pylori y la afección por reflujo duodenogástrico (RDG) son enfermedades frecuentes que pueden coexistir. La posible influencia del reflujo duodenogástrico sobre la infección por Helicobacter pylori es un tema controvertido. Objetivo: estimar el comportamiento histopatológico de la gastritis crónica antral por Helicobacter pylori según la presencia o no de reflujo duodenogástrico e identificar si existen diferencias entre ellos. Métodos: estudio tipo caso-control. Universo: total de pacientes atendidos entre agosto 2011-agosto 2012 en el Servicio de Gastroenterología del Hospital Universitario Vladimir Ilich Lenin de Holguín, con endoscopia y biopsia gástrica antral diagnóstica de gastritis crónica antral e infección por H. pylori, diagnosticadas en el Departamento de Anatomía Patológica del Hospital Pediátrico Provincial Octavio de la Concepción y de la Pedraja según estado de actividad, severidad lesional y densidad de colonización por Helicobacter pylori. Se seleccionaron dos grupos: de estudio o casos con RDG (n = 25) y de control sin RDG (n = 47). Resultados: las formas activas (80%), mayores grados de severidad lesional (68%) y de densidad de colonización de Helicobacter pylori (56%) predominaron en el grupo estudio sin diferencias significativas con el grupo control (P> 0,05). Conclusiones: no existió una relación sinérgica, ni antagónica, entre la infección por Helicobacter pylori y el material refluido respecto a la acción lesiva sobre la mucosa gástrica y la magnitud de la colonización por la bacteria.


Introduction: the chronic antral gastritis for Helicobacter pylori (H pylori) and duodenogastric reflux disorders are frequent affections that can coexist. The possible influence of the duodenogastric reflux disorders on chronic antral gastritis for Helicobacter pylori is a controversial theme. Objective: to estimate the histopathological behavior of the chronic antral gastritis for H. pylori according to the presence or not of duodenogastric reflux. Methods: a control case study was carried out. The universe comprised the total of patients attended during August 2011- August 2012 in Gastroenterology Service of the Teaching Hospital of Holguín, with endoscopy and gastric antral diagnostic biopsy of chronic antral gastritis and infection by H. pylori. Two samples were selected: a study group with duodenogastric reflux (25 patients, 34.7%) and a control group without duodenogastric reflux (47 patients). Results: the active forms (80%), bigger degrees of severity lesion (68%) and of Helicobacter pylori's density of colonization (56%) predominated in the study group without significant differences comparing to the control group (P< 0.05). Conclusions: there were no synergetic and antagonistic relations between the infection for Helicobacter pylori and the flowed back material in relation to the harmful action on the gastric mucosa and the magnitude of the colonization for the bacterium.

RESUMO

La gastritis crónica es una de las 40 enfermedades más frecuentes en Cuba, su etiología es multifactorial y el Helicobacter pylori es el agente causal principal. A los campos magnéticos se le reconocen los efectos antiinflamatorios, analgésico, regenerador de tejidos e inhibidor del desarrollo de gérmenes patógenos. Objetivo: evaluar la utilidad de la magnetoterapia en pacientes con gastritis crónica antral. Métodos: se realizó un estudio cuasi-experimental prospectivo en 30 pacientes, con diagnóstico positivo histológico de gastritis crónica antral. Todos los pacientes recibieron como único tratamiento campo magnético, frecuencia 50 Hz, en región epigástrica en 20 sesiones. Antes y después del tratamiento se tuvo en cuenta evolución de los síntomas, estudio endoscópico con biopsia y la presencia de H. pylori (grado de colonización). Resultados: al finalizar el tratamiento, 22 pacientes (73,3 %) tenían mejoría clínica, en 26 (86,7 %) la gastritis estaba inactiva y en 23 (76,7 %) el grado de severidad de la gastritis fue ligero. Todos los pacientes colonizados por H. pylori tenían un grado ligero. Conclusiones: se considera que la magnetoterapia resulta útil en el tratamiento de la gastritis crónica antral...


"Chronic gastritis is among the 40 most common diseases in Cuba. Its etiology is multifactorial, Helicobacter pylori being the main causal agent. Magnetic fields are known to have antiinflammatory, analgesic and tissue regenerating properties, as well as a capacity to inhibit the development of pathogenic germs. Objective: evaluate the usefulness of magnetotherapy in patients with chronic antral gastritis. Methods: a prospective quasi-experimental study was conducted of 30 patients with a positive histological diagnosis of chronic antral gastritis. All patients received 20 sessions of 50 Hz magnetotherapy on the epigastric area as the only treatment. Before and after the treatment, an endoscopic study with biopsy was performed, and observations were made of the evolution of symptoms and the presence of Helicobacter pylori (degree of colonization). Results: upon completion of the treatment, 22 patients (73.3 %) showed clinical improvement, in 26 (86.7 %) gastritis was inactive, and in 23 (76.7 %) the degree of severity of gastritis was slight. All patients colonized by Helicobacter pylori showed a slight degree. Conclusions: magnetotherapy is considered to be useful in the treatment of chronic antral gastritis...
