ABSTRACT
INTRODUCTION: No published material on the prevalence of celiac disease (CD) in the pediatric population of Argentina has been found up to date. Objective. To estimate the prevalence of CD in a pediatric population (hospital-based sample) from 5 urban districts of Argentina. METHODS: In a cross-sectional descriptive study, we analyzed serum samples from 2219 children, aged 3-16 years old, which had been requested for pre-surgical tests and for physical aptitude certificates for sports in the province of Buenos Aires, and cities of Buenos Aires, Córdoba, Santa Fe and Salta. Children with a previous and accurate diagnosis of CD were also included. IgA class tissue transglutaminase antibodies were determined using serum samples, and those samples which turned out positive were also tested for IgA class endomysium antibodies. A small intestine biopsy was proposed for those who had a positive serology. RESULTS: Between May 2008 and August 2009, 29 positive serologies were found. A total of 22 duodenum biopsies were performed, and 21 turned out compatible with CD. Out of 2219 children, 7 had a previous diagnosis. A prevalence of 1.26% (1:79 children), with female gender predominance (p < 0.023) was found. Ninety percent of the celiac children were over 6 years old (p < 0.021). Silent celiac disease predominated but there was a 33% of symptomatic cases. CONCLUSIONS: The results of the trial show a higher prevalence of CD than expected. The finding of symptomatic patients (33%) suggests the undertaking of different activities to spread the knowledge on this disease and promote the indication for serology test, to avoid complications by means of an early diagnosis.

Introducción. Hasta la fecha del estudio no se hallaron estudios poblacionales publicados sobre prevalencia de enfermedad celíaca en la población pediátrica argentina. Objetivo. Estimar la prevalencia de la enfermedad celíaca en población pediátrica a partir de una muestra de base hospitalaria de cinco distritos urbanos. Método. Diseño descriptivo de corte transversal. Bajo consentimiento informado, participaron 2219 niños, de 3 a 16 años, que realizaban estudios de laboratorio para exámenes prequirúrgicos o certificados de aptitud física deportiva del Conurbano bonaerense, y ciudades de Buenos Aires, Santa Fe, Córdoba y Salta. Se incluyeron niños con diagnóstico previo y certero de enfermedad celíaca dentro de esa población. Se determinaron anticuerpos antitransglutaminasa y, en las muestras positivas, anticuerpo antiendomisio. Se propuso biopsia de intestino delgado a quienes presentaron ambas serologías positivas. Resultados: 29 serologías fueron positivas. Se realizaron 22 biopsias de duodeno, 21 fueron compatibles con enfermedad celíaca y 7 presentaron diagnóstico previo. La prevalencia fue de 1,26% (1:79) IC 95% 0,84-1,81, con predominio del sexo femenino (p <0,039). El 90% de los niños celíacos hallados fueron mayores de 6 años. Las formas clínicas silentes predominaron, pero hubo un 33% de casos sintomáticos. Conclusión. Los resultados en la población estudiada muestran una prevalencia mayor que la esperada. El hallazgo de formas sintomáticas (33%) sugiere emprender acciones de difusión del conocimiento de la enfermedad y ampliar la indicación de serología para obtener diagnóstico precoz.

INTRODUCCIÓN: Hasta la fecha del estudio no se hallaron estudios poblacionales publicados sobre prevalencia de EC en población pediátrica argentina. OBJETIVO: estimar la prevalencia de la EC en población pediátrica de cinco distritos urbanos. MÉTODOS: diseño descriptivo de corte transversal. Se invitó a participar a 2.230 niños, de 3 a 16 años, que realizaban estudios de laboratorio para exámenes prequirúrgicos o certificados de aptitud física deportiva. Se determinaron Anticuerpos Antitransglutaminasa, y en las muestras positivas Anticuerpo Antiendomisio. Se propuso biopsia de intestino delgado a quienes presentaron ambas serologías positivas. Se incluyeron niños con diagnóstico previo de EC que cumplían los criterios de inclusión. La prevalencia se expresó mediante el porcentajey su IC exacto. Las comparaciones entre grupos se efectuaron mediante la prueba exacta de Fisher. RESULTADOS: se testearon los sueros de 2.219 niños, 29 serologías fueron positivas. Se realizaron 22 biopsias de duodeno, 21 fueron compatibles con EC y 7 presentaron diagnóstico previo. La prevalencia fue de 1,26% (1:79)IC 95% 0,84-1.81, con predominio del sexo femenino (p<0,039) e importantes diferencias regionales. El 90% de los niños celíacos hallados fueron > 6 años. Las formas clínicas silentes predominaron pero hubo un 33% de casos sintomáticos. CONCLUSIÓN: los resultados en la población estudiada muestran una prevalencia mayor que estudios previos en adultos. El hallazgo de formas sintomáticas (33%) sugiere emprender acciones de difusión del conocimientode la enfermedad y ampliar la indicación de serología para obtener diagnóstico precoz.
INTRODUCTION: up the date of this study, published material about the prevalence of CD in pediatric population in Argentina has not been found. OBJECTIVE: to estimate CD prevalencein a pediatric population of 5 urban districts. METHODS: descriptive and cross sectional cut design. Were invited 2.230 children, between 3 and 16 years, which had been requested forpre-surgical studies and physical aptitude certificates for sports. IgA class tissue transglutaminase antibodies were determined and to positive samples IgA class endomysium antibodies. A small intestine biopsy was proposed for those who had both positive serology. Children with a previous diagnosis of CD who met the inclusion criteria were included. The prevalence was expressed by means of the percentage and its exact confidence interval and the comparisons between groups were performed using Fisher´s exact test. RESULTS: 2.219 children´s sera were studied. 29 were positive serologies. 22 duodenum biopsies were performed, 21 turned out compatible with CD. 7 children presented a previous diagnosis. A prevalence of 1.26% (1:79) CI 95% (0,84-1,81) was found, with female sex predominance ( p<0.039) and important regional differences as well. Ninety percent of the celiac children found were> 6 years Silent clinical manifestations predominated but there were 33% of symptomatic cases. CONCLUSIONS: the results in the study population showed a higher prevalence than previous studies in adults. The finding of symptomatic manifestations (33%)suggests actions to spread the knowledge of this disease promotingthe indication of serology for early diagnosis.
