ABSTRACT
Objective: The objective of this study was to determine the prevalence of celiac disease (CD) in adults with autoimmune thyroid disease (ATD) from the endocrinology outpatient setting in a university hospital in Southern Brazil. Subjects and methods: From the years 2007 to 2011, 254 patients with ATD were enrolled consecutively, Grave’s disease was diagnosed in 143 (56.3%) and Hashimoto’s thyroiditis in 111 (43.7%) of them. All patients answered a questionnaire related to symptoms that could be associated with CD and serum samples to screen for IgA anti-endomysial (EmA-IgA) were collected. EmA-IgA-positive patients were offered upper gastrointestinal endoscopy and biopsy of duodenum. Results: A total of 254 patients were included; 222 (87.4%) female, mean age 45.4 ± 13.43 years (18 to 79 years). EmA-IgA was positive in seven patients (2.7%) and five done endoscopy with biopsy. Of these, three diagnosis of CD was confirmed (1.2%). All the three patients with CD had higher EmA-IgA titration, were female and had Hashimoto’s thyroiditis. Like other patients with ATD, CD patients had nonspecific gastrointestinal symptoms, such as heartburn and gastric distention. In our study, one in each 85 patients confirmed the diagnosis of CD. Conclusion: We found a prevalence of 1.2% (1:85) of confirmed CD among Brazilian patients with ATD. Although some IgA-EmA positive patients had Graves’ disease and one was male, all three patients with confirmed CD were female and had Hashimoto’s thyroiditis.

Objetivo: O objetivo do presente estudo foi determinar a prevalência de doença celíaca (DC) em adultos com doenças autoimunes de tireoide (DAT) que foram atendidos em um serviço de endocrinologia de um hospital universitário do sul do Brasil. Sujeitos e métodos: Entre os anos de 2007 a 2011, 254 pacientes com DAT foram consecutivamente incluídos, sendo 143 (56,3%) desses diagnosticados com doença de Graves e 111 (43,7%) com doença de Hashimoto. Todos os pacientes responderam a um questionário relatando sintomas que poderiam ser associados com DC, e amostras de soro para a pesquisa de anticorpo antiendomisial (EmA-IgA) foram coletadas. Os pacientes com sorologia positiva foram encaminhados para endoscopia gastrointestinal com biópsia duodenal. Resultados: No total, 254 pacientes foram incluídos, sendo 222 (87,4%) mulheres com média de idade 45,4 ± 13,43 anos (18 a 79 anos). EmA-IgA foi positivo em sete (2,7%) pacientes e cinco fizeram endoscopia com biópsia. Desses, três (1,2%) tiveram o diagnóstico de DC confirmada. Todos os três pacientes com DC apresentaram altos títulos de EmA-IgA, eram mulheres e tinham doença de Hashimoto. Assim como outras pacientes com DAT, os pacientes celíacos tinham sintomas gastrointestinais inespecíficos, como queimação e distensão gástrica. Em nosso estudo, um em cada 85 pacientes com DAT tiveram o diagnóstico de DC confirmado. Conclusão: Em nosso estudo, foi observada prevalência de 1,2% (1:85) de DC confirmada entre os pacientes com DAT, sendo todas mulheres e com doença de Hashimoto.
