Martínez Marín,Julián David; Henao Riveros,Sandra Consuelo;
Revista Colombiana de Gastroenterologia , 2009,
Abstract: an observation study, which analyzed cases and controls, was realized with 1850 adults subjected to upper digestive endoscopy, who were sent to the endocentro ltda. medical center in bogota, colombia, due to diverse symptoms, and who had not received previous treatment with antibiotics, antibacterial medication or medication that altered gastric secretion. chronic follicular gastritis was found in 8.4% (102 patients), 73 women and 29 men, with an average age of 33.5 years. inflammation activity was detected in 99% and h. pylori in 98% of the patients. the controlled group was made up of 1100 patients with other kinds of chronic gastritis different from follicular gastritis. with these 1100 patients, 698 women and 412 men, with an average age of 48.3 years, inflammatory activity was found in 72.1% and h. pylori in 63.3%. in the feminine gender, a minimum risk increase was determined, without presenting changes in chronic follicular gastritis of statistical significance or = 1.48 (95% ic 0.93-2.41). in the young patients who were less than 35 years old and in those infected by h. pylori, a higher risk for follicular gastritis changes was observed or = 7.57 (95% ic 4.82-11,97) and or =28.94 (95% ic 7.72-243.23) respectively. a greater inflammatory activity was observed in patients with chronic follicular gastritis, or = 38.96 (95% ic 6.76-1558.64).

Abstract: Se realizó un estudio observacional, analítico de casos y controles, con 1.850 adultos sometidos a endoscopia digestiva alta remitidos al centro médico Endocentro Ltda. en Bogotá DC, por diversos síntomas y que no hubieran recibido tratamiento previo con antibióticos, antibacterianos o medicamentos que alteren la secreción gástrica. Se encontró una prevalencia para la gastritis crónica folicular de 8,4% (102 pacientes), 73 mujeres y 29 hombres, con edad promedio de 33,5 a os, se detectó la presencia de actividad inflamatoria en el 99% y de H. pylori en el 98% de los pacientes. El grupo control estuvo formado por 1.100 pacientes con otros tipos de gastritis crónica diferente a la folicular, 698 mujeres y 412 hombres, edad promedio de 48,3 a os y presencia de actividad inflamatoria y de H. pylori en el 72,1% y 63,3% respectivamente. Se determinó, en el género femenino, un aumento mínimo del riesgo, sin significancia estadística de presentar cambios de gastritis crónica folicular OR = 1,48 (IC 95% 0,93-2,41). En los pacientes jóvenes menores de 35 a os y en los infectados por H. pylori se observó un riesgo aumentado de presentar cambios de gastritis folicular OR = 7,57 (IC 95% 4,82- 11,97) y OR =28,94 (IC 95% 7,72- 243,23) respectivamente. Se observó mayor actividad inflamatoria en los pacientes con gastritis crónica folicular, OR = 38,96 (IC 95% 6,76-1558,64).

Abstract: Se presenta un grupo de 75 pacientes adultos colombianos, con diagnóstico de gastritis crónica atrófica de acuerdo a los criterios de Sydney, de los cuales el 28% presentó deficiencia de vitamina B12 y al 9% se le diagnóstico anemia perniciosa. Las cifras de hemoglobina, volumen corpuscular medio no se correlacionaron con el déficit de vitamina B12. No se encontró una asociación estadística del déficit de la vitamina B12 con el género, edad mayor de 60 a os de los pacientes o con la presencia del Helicobacter pylori (H. pylori). La edad promedio de los pacientes con déficit de vitamina B12 o con anemia perniciosa es menor a la que tradicionalmente se reporta para estas enfermedades We present a group of 75 Colombian adults who were diagnosed with chronic atrophic gastritis in accordance with the Sydney criteria. 28% of the group had vitamin B12 deficiencies: 9% were diagnosed with Pernicious anemia. Hemoglobin and mean corpuscular volume were not correlated with vitamin B12 deficiency. We found no statistical association of vitamin B12 deficiency with gender, patients over 60 years of age, or the presence of Helicobacter pylori (H. pylori). The average age of patients with vitamin B12 deficiency or pernicious anemia is less than that traditionally reported for these diseases

Abstract: Antecedentes. La aparición de aislamientos de Mycobacterium tuberculosis resistentes a los medicamentos ha hecho que se busquen métodos más rápidos y confiables para la determinación de la susceptibilidad a las drogas antituberculosas. Objetivo. Determinación de la susceptibilidad a drogas antituberculosas de primera línea en aislamientos de M. tuberculosis utilizando el método del tubo indicador de crecimiento micobacteriano (MGIT). Material y métodos. Se estudiaron 49 aislamientos de M. tuberculosis procedentes del laboratorio de micobacteriología del departamento de Microbiología de la Universidad Nacional de Colombia. Se evaluó y comparó el método MGIT para la determinación de la resistencia o susceptibilidad a rifampicina, isoniacida, etambutol y estreptomicina con la prueba de oro, el método de las proporciones múltiples (PM). Resultados. Por el método de las PM de los 49 aislamientos, 26 (53.0%) fueron sensibles a los cuatro antibióticos, 12 (24.5%) resistentes a un antibiótico y 11 (22.5%) a más de un antibiótico. Por el método MGIT de los 49 aislamientos, 31 (63.3%) fueron sensibles a los cuatro antibióticos, ocho (16.3%) resistentes a un antibiótico y 10 (20.6 %) resistentes a más de un antibiótico. Los porcentajes de concordancia observada oscilaron entre 83.7 y 97.9% y el índice kappa estuvo entre 0.61 y 0.83 para los diferentes antibióticos analizados. La sensibilidad del método MGIT a rifampicina, isoniacida, etambutol y estreptomicina fue de 88.9, 95.2, 62.5 y 58 por ciento respectivamente y la especificidad fue 97.7, 92.3, 98.8 y 98.4 por ciento respectivamente. Por el método MGIT se aislaron cepas resistentes de M. tuberculosis en un tiempo promedio de 7.85 días. Conclusiones. El método MGIT permite la obtención de resultados confiables principalmente a isoniacida y rifampicina que son los antibióticos que determinan la multirresistencia del M. tuberculosis y en menor medida para estreptomicina y etambutol.

Abstract: El consumo crónico de inhibidores de la bomba de protones (IBP) para el manejo de diversas enfermedades, en gran número de pacientes en todo el mundo, ha generado informes controversiales, que asocian esta práctica con el desarrollo de cambios atróficos de la mucosa gástrica y sus potenciales consecuencias. Se desarrolló un estudio de casos y controles con 311 pacientes remitidos al Endocentro Ltda., 156 de ellos informaron consumo crónico de IBP por más de 3 a os (promedio de 5,1 a os), el grupo control constituido por 155 personas que negaron el consumo de medicamentos que inhiban la secreción gástrica hasta dos a os previos al estudio. El análisis estadístico no mostró aumento del riesgo de desarrollar atrofia gástrica corporal en los consumidores de IBP (OR= 0,99 95% IC -0,01-1,99, p<0,79), sin embargo, se observó aumento del riesgo de atrofia de la mucosa corporal en los consumidores crónicos de IBP e infectados por Helicobacter pylori (OR= 1,13 95% IC 0,12-2,14, p<0,0001).
