BACKGROUND: For the last 15 years, infection from Helicobacter pylori (H. pylori) has been recognized in gastritis pathogenesis, and is known to trigger an important inflammatory response in these patients. AIM: To determine the association between follicular gastritis and the infection of H. pylori in children seen at a public hospital in Peru. METHODOLOGY: An analytic, cross-sectional study was conducted on all the children treated at the Hospital Nacional Docente Madre "Niño San Bartolomé" in Lima, Peru, within the time frame of 2011-2012. All the personal data from the patients' medical histories and endoscopic procedures were collected. The crude prevalence ratios (PR) were obtained and adjusted (aPR) with their 95% confidence intervals (95%CI), using generalized linear models with the binomial family and log link function. RESULTS: A total of 123 children met the study criteria. Forty-eight (39%) of the study sample were girls and the mean age of the children was 12 years. H. pylori was present in 44% of the sample and 9% presented with more than 100 bacteria per field (classified as +++). Thirty-five percent of the children had esophagitis due to concomitant reflux. The presence of H. pylori was associated with follicular gastritis (P<.01; PRa: 2.3; 95% CI:1.49-3.49), adjusted by the children's age. CONCLUSIONS: Based on the data analyzed, it was concluded that the children with follicular gastritis had a greater likelihood of having H. pylori than those that did not present with gastritis. These results can be extrapolated to other similar populations and should be evaluated in each setting so that this does not become a public health problem within the next few years. / Peer review

El presente es un estudio epidemiológico, descriptivo, retrospectivo de tipo deductivo que se realizó en el Hospital Nacional Guillermo Almenara Irigoyen, perteneciente a EsSalud, Hospital de IV nivel de la seguridad social, comprendiendo el periodo entre agosto 1998 - octubre 2001, con el objetivo de establecer relación de causalidad entre medicamento administrado (causa) y la aparición de enfermedades (efecto) tales como: Anemia Aplásica Adquirida, Hepatitis Medicamentosa y Gastritis Hemorrágica. Se trabajó con las historias clínicas de pacientes, en quienes se había diagnosticado las enfermedades comprendidas en el estudio; los pacientes pertenecían a los diferentes servicios del hospital. Los periodos de estudio fueron para: anemia aplásica adquirida de agosto de 1998 a agosto del 2001, hepatitis medicamentosa de enero de 1999 a octubre del 2001, y gastritis hemorrágica del 1 de enero del 2000 al 31 de diciembre del 2000. El análisis deductivo se realizó mediante el Algoritmo de Karch y Lasagna modificado por Naranjo y colaboradores. Los criterios considerados para establecer relación de causalidad entre agente etiológico (medicamento) y la enfermedad inducida fueron: Relación en el tiempo, entre la administración del medicamento sospechoso y la enfermedad inducida por drogas; la resolución favorable de los signos, síntomas y pruebas de laboratorio después del retiro del agente etiológico probable; los datos de laboratorio y exámenes clínicos que relacionen en el tiempo a la droga y la aparición de la enfermedad en estudio. Se estudiaron 18 casos de anemia aplásica adquirida, la edad promedio fue de 26.7 años, el 27.8% fue inducido por drogas mientras otro 27.8% fue inducido por otro agente etiológico y el 50% de los casos presentaba una enfermedad concomitante. Se identificaron 15 casos de hepatitis medicamentosa, la edad promedio fue de 44 años, el 40 % estaban entre la edad de 40 – 50 años y el 93.3% de los casos presentaba otra enfermedad concomitante. Encontramos 41 casos de gastritis hemorrágica, la edad promedio fue de 63 años, el 31.7% estaban entre la edad de 70 – 80 años, el 48.8 % fue inducido por drogas mientras el 29.3% fue inducido por otra causa no medicamentosa, el 53.7 % presentaba otra enfermedad concomitante. Se concluyó que el 27.8% de los casos de anemia aplásica y el 48.8% de los casos de gastritis hemorrágica tenían como agente etiológico probable a drogas, los agentes quimioterapicos con un 11.1% (5-fluorouracilo, doxorubicina, metotrexate) en anemia aplásica, los agentes antituberculosos con un 20.1% ( isoniazida, rifampicina, pirazinamida, etionamida) en hepatitis medicamentosa y los AINES con un 29.3% (ibuprofeno, piroxicam) en Gastritis hemorrágica fueron los principales agentes etiológicos probables de estas enfermedades estudiadas. / -- This is an epidemiologic, descriptive, retrospective study of deductive tipe done in Hospítal Nacional Guillermo Almenara Irigoyen of EsSalud, Hopital of fourth level of social security, in period from august 1998 to October 2001 and the objective is to stablish relation between administered drug (cause ) and apparition of illness (effect) such as: acquired aplasic anemia, hepatitis induced by drugs and hemorrhagic gastritis. Clinic histories of patients with diagnostic of illness included in study were material of work; patients were of different services of hospital. Period of study was: for acquired aplasic anemia from august 1998 to august 2001, for hepatitis induced by drugs from january 1999 to october 2001, and for hemorrhagic gastritis from january 1 2000 to december 31 2000. Deductive analysis was done with Karch and Lasagna´s algoritme modified by Naranjo and collaborators. Cryteria considered to stablish relation of causality between etiologic agent (drug) and induced illness were: relation in time between administration of suspect drug and illness induced by drug; favorable remission of signs, symptoms and laboratoty tests after quit suspect etiologic agent, laboratory tests and clinic surveys wich were related in time drug with apparition of illness in study. Eighteen cases of acquired aplasic anemia were studied, the average age was 26.7 years; the 27.8% was produced for drugs while other 27.8% was induced for other etiologic agent and 50% of cases showed a concomitant disease. 15 cases of hepatitis produced for drugs were identified, the average age was 44 years, the 40%, the 40% was between 40 50 and 93.3% of cases showed other concomitant disease. 41 cases of hemorrhagic gastritis were discovered, the average age was 63 year, the 31.7% was between 70 – 80 years; the 48.8% was produced for drugs while 29.3% was induced for other cause and 53.7% presented other concomitant disease. 41 cases of hemorrhagic gastritis were discovered, the average age was 63 year, the 31.7% was between 70 – 80 years; the 48.8% was produced for drugs while 29.3% was induced for other cause and 53.7% presented other concomitant disease. Conclusion, the 27.7% of aplasic anemia cases and 48.8% of hemorragic gastritis cases were produced probably for drugs; the quimioterapic agents whit a 11.1% (5-fluorouracile, doxorubicin, metothrexate) in aplasic anemia; the antituberculosis agents with a 20.1% (isoniazida, rifampin, pyrazinamide, ethionamide) in hepatitis produced for drugs and the AINES with a 29.3% (ibuprofen, piroxicam) in hemorrhagic gastritis, which were the principal etiologic agents who produced probably the different studied diseases.
