ABSTRACT
Introducción: la enfermedad celiaca puede estar asociada en forma silente a las tiroiditis autoinmunes. Objetivo: determinar la presencia de enfermedad celiaca silente en pacientes con tiroiditis autoinmunes. Metodología: estudio observacional, prospectivo, multicéntrico realizado en pacientes adultos con tiroiditis de Hashimoto y enfermedad de Graves de tres centros hospitalarios de Paraguay en años 2018-2019. Se determinó la presencia anticuerpos IgA antitransglutaminasa e IgA sérica en aquellos que aceptaron participar del estudio. Se midieron además variables demográficas y clínicas. El estudio fue aprobado por el Comité de Ética de la Universidad Nacional de Itapúa.Resultados: se contactaron 87 pacientes, pero la muestra final estuvo constituida por 22 sujetos. La edad media fue 50 años, con predominio del sexo femenino (77%). Se detectaron anticuerpos para enfermedad celiaca en 3 casos (13%) y todos fueron confirmados con biopsia duodenal. Conclusiones: la frecuencia de enfermedad celiaca silente en pacientes con tiroiditis de Hashimoto y enfermedad de Graves fue 13%.
Introduction: celiac disease may be asymptomatically associated with autoimmune thyroiditis.Objective: to determine the presence of silent celiac disease in patients with autoimmune thyroiditis.Methodology: we carried out a observational, prospective, multicenter study in adult patients with Hashimoto's thyroiditis and Graves' disease from three hospitals in Paraguay in the years 2018-2019. The presence of IgA antitransglutaminase and serum IgA antibodies was determined in those who agreed to participate in the study. Demographic and clinical variables were also measured. The study was approved by the Ethics Committee of the National University of Itapúa. Results: 87 patients were contacted, but the final sample was established with 22 subjects. The mean age was 50 years, with a predominance of the female (77%). Antibodies to celiac disease were detected in 3 cases (13%) and all were confirmed with a duodenal biopsy. Conclusions: the frequency of silent celiac disease in patients with Hashimoto's thyroiditis and Graves' disease was 13%.

OBJETIVO: Este estudo objetivou identificar a soroprevalência da doença celíaca em adolescentes de escolas públicas da cidade de Salvador, Bahia. MÉTODO: Trata-se de um estudo transversal com amostra probabilística de 1.213 adolescentes de 11 a 17 anos, de ambos os sexos. O índice de massa corporal foi utilizado para o diagnóstico do estado nutricional, adotando-se os percentis segundo idade e sexo, propostos pela World Health Organization. O anticorpo anti-transglutaminase humana da classe imunoglobulina A (anti-tTG-IgA) foi adotado como teste sorológico para triagem da doença celíaca e foi determinado pela técnica do ensaio imunoabsorvente ligado à enzima (ELISA). Foi realizada análise descritiva, utilizando-se a proporção e a média (desvio padrão). RESULTADOS: O sexo feminino predominou entre os adolescentes, e a maioria encontrava-se com adequado estado nutricional. O anticorpo anti-tTG-IgA foi positivo em 6/1.213 (0,49%) adolescentes. CONCLUSÃO: A soroprevalência de doença celíaca entre os adolescentes estudados foi 0,49%. Novas investigações são necessárias para confirmar a prevalência de doença celíaca nessa faixa etária. .
OBJECTIVE: This study aimed to identify the seroprevalence of celiac disease in adolescents from public schools in the city of Salvador, Bahia. METHODS: This was a cross-sectional study with probabilistic sample of 1,213 adolescents, aged 11 to 17 years old, of both genders. The body mass index was used to determine the participants' nutritional status based on the percentiles for age and gender recommended by the World Health Organization. Measurement of the anti-human transglutaminase immunoglobulin A (anti-tTG-IgA) antibody was established as the specific screening test for celiac disease, which involved an enzyme-linked immunosorbent assay (ELISA). Descriptive analysis was performed using proportions and means (standard deviation). RESULTS: The female gender prevailed in the sample, and most of the participants had normal weights. The anti-tTG-IgA antibody was positive in 6/1,213 (0.49%) adolescents. CONCLUSION: The seroprevalence of celiac disease was 0.49% in the investigated adolescents. Further studies are necessary to establish the prevalence of celiac disease in this age range. .

OBJECTIVE: Celiac disease is a permanent enteropathy caused by the ingestion of gluten, which leads to an immunemediated inflammation of the small intestine mucosa. The prevalence of celiac disease varies among different nations and ethnic backgrounds, and its diversity is determined by genetic and environmental factors. São Paulo city is one of the largest cities in the world, with a vast population and an important history of internal migratory flow from other Brazilian regions, as well as immigration from other, primarily European, countries, resulting in significant miscegenation. The aim of the present study was to estimate the prevalence of adults with undiagnosed celiac disease among blood donors of São Paulo by collecting information on the ancestry of the population studied. METHODS: The prevalence of celiac disease was assessed by screening for positive IgA transglutaminase and IgA endomysium antibodies in 4,000 donors (volunteers) in the Fundação Pró-Sangue Blood Center of São Paulo, São Paulo, Brazil. The antibody-positive subjects were asked to undergo a small bowel biopsy. RESULTS: Of the 4,000 subjects, twenty-four had positive tests, although both antibody tests were not always concordant. For example, ten subjects were positive for IgA tissue transglutaminase only. In twenty-one positive patients, duodenal biopsies were performed, and the diagnosis of celiac disease was confirmed in fourteen patients (Marsh criteria modified by Oberhuber). In this group, 67% claimed to have European ancestry, mainly from Italy, Portugal and Spain. CONCLUSION: The prevalence of celiac disease is at least 1:286 among supposedly healthy blood bank volunteers in São Paulo, Brazil.
