Hiperplasia linfoide folicular gástrica e infección por Helicobacter pylori en adultos colombianos Gastric Follicular Lymphoid Hyperplasia and Infection by Helicobacter pylori in Colombian adults

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). 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 7.7
