Introduction: Although the association between diabetes mellitus type 1 (T1DM) and celiac disease (CD) is well established; there are only a few studies that focus on South American children, haplotypes and their possible associations. Objective: To determine the prevalence of CD markers in a group of children with T1DM and to analyze the associated clinical, immunological and genetic manifestations. Methods: A prevalence study focusing on children with T1DM who were assessed based on variables including sociodemographics, anthropometric information, disease characteristics, laboratory results and family medical history. In partitipants a positive tTG2 (Ig A anti-transglutaminase), a duodenal biopsy and genotype were performed. The proportion of children with T1DM and CD was estimated (CI 95%). Determinations of central tendency, univariate and bivariate analysis, were also performed; p <0.05 was considered significant. Results: Thirteen (8.4%) of the 155 children (53.6% girls, 11.0 ±3.6 years, 2-18 years) with T1DM were tTG2 positive, four had CD (2.6%), seven had potential CD (4.5%) and nine were HLA DQ2/DQ8 positive (5.8%). Children with T1DM and CD had their last ketoacidotic episode (21.5 ±30.4 months versus 69.5 ±38.8 months, p= 0.0260) earlier than children with T1DM and potential CD. There were no differences with anthropometry or with the laboratory results regarding glycemic control. Conclusions: The prevalence of CD in these children with T1DM is higher than that reported in other South American countries. The prevalence of CD was found to be associated with the time of presentation of T1DM and its main allele, the DQ2/DQ8. These findings are different from what has been described in other places around the world.
Introducción: La patogénesis de los desórdenes gastrointestinales funcionales (DGFs) es multifactorial.Objetivo: Investigar la prevalencia de DGFs luego del antecedente de dengue.Materiales y métodos: Estudio de prevalencia en niños entre 8-18 años de edad. Se tomaron variables sociodemográficas, clínicas y el antecedente del último año de dengue diagnosticado en urgencias. Se aplicó el Cuestionario para Síntomas Gastrointestinales Pediátricos Roma III en Español para DGFs. El análisis estadístico incluyó el cálculo del OR, con IC95% y Fisher a dos colas, con una p<0.05 significativo.Resultados: Fueron incluidos 4023 niños con edad 11,9±2,3 años y 50,1% masculinos. La prevalencia para presentar al menos 1 DGFs fue 23.0% y del antecedente de haber presentado dengue en el último año del 7,5%; habiendo predominio en escolares entre 8-12 años de edad (OR=1,56 IC95%=1,20-2,04 p=0,0006) y con al menos 1 DGFs (OR=1,98 IC95%=1,53-2,56 p<0,0001). En los niños que por antecedente presentaron dengue en el último año, hubo diferencias significativas cuando tenían padres separados/divorciados.Conclusión: En este grupo de niños, los DGFs son frecuentes, presentándose mayor oportunidad de tener algún DGFs en los escolares entre los 8-12 años de edad cuando se tiene el antecedente de dengue diagnosticado en un servicio de urgencias.
Background: Peutz-Jeghers syndrome (PJS) is a rare autosomal dominant inherited disease characterized by the development of polyps in the gastrointestinal tract, mucocutaneous pigmentation, and the risk of developing malignant neoplasms. This study aimed to analyze the epidemiological, clinical, and histopathological data of patients with PJS treated in a tertiary pediatric hospital. Methods: We conducted a retrospective observational study to describe the epidemiological, clinical, endoscopic, and histological characterization of patients with PJS treated in a tertiary pediatric hospital in Mexico. Results: We included 13 cases with a male-female ratio of 1.16:1. Abdominal pain was the main reason for consultation, followed by rectorrhagia. Patients showed mucocutaneous pigmentation and polyps in the gastrointestinal tract, frequently of the hamartomatous type, although inflammatory polyps, follicular hyperplasia, and adenomatous polyps were also found. Among the complications, there was a high prevalence of emergency surgery secondary to abdominal obstructive processes, the main reason for first-time consultation in these patients. Conclusions: The main clinical manifestations were mucocutaneous pigmentation, abdominal pain, and rectorrhagia. PJS should be included in the differential diagnosis in the presence of intestinal obstruction. The diagnosis of PJS should not be excluded if hamartomatous polyps are not evident on the first endoscopy. Nutritional assessment should be included due to the risk of presenting some degree of malnutrition.
Introducción. La patogenia de los trastornos funcionales gastrointestinales involucra agentes infecciosos como los virus.Objetivo. Investigar el desarrollo de trastornos funcionales gastrointestinales en niños, a los 3, 6, 9 y 12 meses después de un episodio de dengue no grave sin signos de alarma.Materiales y métodos. Se hizo un estudio de cohorte de 73 niños con diagnóstico de dengue no grave sin signos de alarma atendidos en el Hospital Universitario del Valle “Evaristo García” y de 62 niños sanos de Cali, Colombia. Mediante el ‘Cuestionario para síntomas gastrointestinales pediátricos Roma III’ (Questionnaire for Pediatric Gastrointestinal Symptoms Rome III, QPGS-III), se determinaron los trastornos gastrointestinales funcionales a los 3, 6, 9 y 12 meses de seguimiento después de un episodio de dengue no grave sin signos de alarma. Se calcularon las medidas de tendencia central, riesgo relativo y prueba de ji al cuadrado, y se usó la prueba exacta de Fisher con un nivel de significación (p) menor de 0,05.Resultados. Se incluyeron 135 niños de 10,7±1,9 años; 51,1 % de ellos correspondía al sexo masculino y 19,3 % presentaba algún trastorno funcional gastrointestinal (9,6 % con dolor abdominal relacionado). El riesgo de presentar algún trastorno funcional gastrointestinal con dolor abdominal relacionado a los 3, 6, 9 y 12 meses de seguimiento en niños con dengue no grave sin signos de alarma fue mayor que sin dicho antecedente, pero sin diferencias significativas.Conclusión. Los resultados del estudio sugieren que el dengue no grave sin signos de alarma no incrementó el riesgo de trastornos gastrointestinales funcionales y dolor abdominal relacionado a lo largo de 12 meses de seguimiento.
