RESUMEN

ABSTRACT BACKGROUND: Familial Mediterranean fever and celiac disease share some common clinical features such as abdominal pain, diarrhea, arthralgia and arthritis. Also, both of the diseases are associated with many inflammatory and autoimmune diseases. Previous studies have shown the association between familial Mediterranean fever (FMF) and different clinical conditions. OBJECTIVE: We aimed to investigate the relationship between celiac disease and colchicine-resistant familial Mediterranean fever (crFMF) disease. METHODS: This prospective study was conducted at the Department of Pediatric Gastroenterology and Pediatric Rheumatology from October 2015 to August 2016. A total of 24 patients with crFMF were included in the study. We used 60 sex- and age-matched healthy subjects as a control group. Levels of total IgA and tissue transglutaminase (tTG) IgA antibody were measured in both groups. Those with increased level of tTG IgA were tested for anti-endomysium IgA antibodies (EMA). Gastroduodenoscopy and intestinal biopsy were planned for a definite diagnosis of celiac disease in patients with positive EMA. RESULTS: Of the 24 patients in this study, 18 (75.0%) were female. Only 4 (16.6%) of 24 patients were positive for tTG IgA. Patients with positive tTG IgA were then tested for EMA IgA antibodies and none of them had a positive result. Only one (1.6%) subject from the control group was positive for tTG IgA but EMA positivity was not detected. CONCLUSION: We did not found celiac disease in 24 children with crFMF. Since crFMF disease is rarely seen in general population, further studies with more patients are needed to provide more precise interpretation.


RESUMO CONTEXTO: A febre familiar do Mediterrâneo e a doença celíaca compartilham algumas características clínicas comuns, tais como dor abdominal, diarreia, artralgia e artrite. Além disso, ambas as doenças são associadas a muitas doenças auto-imunes e inflamatórias. Estudos anteriores mostraram associação entre febre familiar do Mediterrâneo e diferentes condições clínicas. OBJETIVO: Investigar a relação entre doença celíaca e doença de febre familiar do Mediterrâneo colchicina-resistente (FMFcr). MÉTODOS: Foi realizado um estudo prospectivo no departamento de Gastroenterologia pediátrica e Reumatologia pediátrica de outubro de 2015 até agosto de 2016. Um total de 24 pacientes com FMFcr foram incluídos. Sessenta indivíduos saudáveis combinados por sexo e idade foram utilizados como um grupo de controle. Os níveis de IgA total e transglutaminase tissular (tTG) anticorpo IgA foram medidos em ambos os grupos. Aqueles com maior nível de tTG IgA foram testados para anticorpos de IgA antiendomísio (EMA). Gastroduodenoscopia e biópsia intestinal foram planejadas para um diagnóstico definitivo da doença celíaca em pacientes com EMA positivo. RESULTADOS: Dos 24 pacientes neste estudo, 18 (75,0%) eram do sexo feminino. Somente 4 (16,6%) de 24 pacientes foram positivos para tTG IgA. Pacientes com tTG IgA positivo então foram testados para anticorpos IgA de EMA, e nenhum deles teve um resultado positivo. Somente um (1,6%) indivíduo do grupo controle foi positivo para tTG IgA, mas a positividade EMA não foi detectada. CONCLUSÃO: Não encontramos a doença celíaca em 24 crianças com FMFcr. Desde que a doença FMFcr é raramente vista na população em geral, estudos com mais pacientes são necessários para fornecer interpretação mais precisa.

RESUMEN

OBJECTIVE: Helicobacter pylori ( H.pylori ) infection is usually acquired in early childhood. Invasive techniques used for diagnosis of H.pylori infection require endoscopic examination which is expensive and inconvenient and may cause complications. The aim of this study was to evaluate the performance of a new noninvasive diagnostic method, stool antigen test for H.pylori in untreated children with recurrent abdominal pain. METHODS: Eighty children (35 female, 45 male) who have undergone upper gastrointestinal endoscopy due to recurrent abdominal pain were included in the study. The H.pylori stool antigen test (HpSA) is based on a sandwich enzyme immunoassay with antigen detection. HpSA sensitivity, specificity, and positive and negative predictive values were determined with reference to the results of both histology and rapid urease test as a gold standard ( H. pylori status). RESULTS: While 49 of the 80 children (61%) tested were positive for H.pylori according to the results of both histology and rapid urease test, 28 children had negative H.pylori status. Among those 49 children, 48 were found to be positive by HpSA. Of 28 patients with negative H.pylori status, 28 were H.pylori -negative also in the stool test. The sensitivity, specificity, and positive and negative predictive values of HpSA were found to be 98%, 100%, 100%, and 96.5%, respectively. CONCLUSION: These findings have demonstrated that HpSA as a relatively simple, inexpensive and time saving noninvasive test is a reliable method for detection of H.pylori infections in children.
