[Comparing frequency of celiac disaase in patients with diabetes mellitus type I and non-diabetic, healthy persons]

Several studies and research have shown a higher prevalence of celiac disease [CD] and elevation of serum antibody [AGA-IgA and IgA-tTG and EMA-IgA] in patient with diabetes mellitus type I [T1DM] in versus general and non-diabetic population. Thus screening of CD is recommended in T1DM]. This study was conducted to compare frequency of celiac disease in patients with T1DM and healthy persons. As a case-control study,60 patient with T1DM that reffered to endocrine clinic of Qazvin's Boo-Ali hospital, in nearly one year period were enrolled as case group. 60 non-diabetic healthy subjects with age and sex matched, were selected as control group. Blood levels of Total IgA, AGA-IgA and IgA-tTG were measured in all of them, subjects who had elevated of both AGA-IgA and IgA-tTG underwent an upper GI endoscopy and biopsy was done from distal part of duodenum. Any one in case group hadn't IgA deficiency. 14 subjects in control and 12 subjects in case group had positive AGA-IgA that there was no significant difference between them. 2 subject of case group had positive IgA-tTG. Duodenal biopsy in 1 of 14 cases who had elevated AGA-IgA]1 of 2 cases who had elevated IgA-tTG], revealed total villous atrophy indicating CD [Type IIIC with revised Marsh criteria 2001] and in other cases pathologic findings were normal or with nonspecific changes. Frequency of CD in T1DM in our study is 1.67%. There is not any significant difference between case and control groups in prevalence of Celiac disease. But we conclused that screening with AGA-IgA is not a reliable screening test for CD, because there is not significant difference between T1DM and general population

Sensibilidad y especificidad de los anticuerpos antigliadina y antiendomisio realizados en el Laboratorio de Inmunología del Centro Hospitalario Pereira Rossell / The sensibility and specificity of tests using antigliadin and antiendomisin antibodies in the Immunology Laboratory of the Pereira Rossell Hospital Centre

La enfermedad celíaca se presenta con una gran heterogeneidad: formas sintomáticas, silentes y latentes. La determinación de anticuerpos antigliadina y antiendomisio es útil para definir a qué pacientes realizar biopsia de intestino delgado y para el seguimiento de los celíacos ya conocidos. Estas técnicas fueron incorporadas en 1994 en el Centro Hospitalario Pereira Rossell. Objetivo: Conocer la sensibilidad y especificidad de los anticuerpos antigliadina (IgG) y antiendomisio (IgA) para el diagnóstico de enfermedad celíaca, determinados por técnica de inmunofluorescencia en la Sección de Inmunología del Laboratorio Central del Centro Hospitalario Pereira Rossell y aplicados a población hospitalaria. Se evaluaron los resultados de la serología tomando como patrón de oro la anatomía patológica de la biopsia de intestino delgado. Para el diagnóstico de enfermedad celíaca se siguieron los criterios de 1990 de la Sociedad Europea de Gastroenterología Pediátrica y Nutrición. Se evaluó la serología de 65 niños que recibían gluten al momento de la extracción de sangre: 50 celíacos y 15 no celíacos (con biopsia normal). La sensibilidad y la especificidad fueron de 94 por ciento y 80 por ciento para los anticuerpos antigliadina y de 94 por ciento y 93 por ciento para los antiendomisio respectivamente. Estos resultados son similares a los comunicados por los mejores laboratorios a nivel internacional.

Prevalencia de enfermedad celíaca en niños y adolescentes diabéticos / Prevalence of celiac disease in diabetic children and adolescents

Background: Celiac disease is more common in patients with insulindependent diabetes than in the general population. Aim: To detect celiac disease in diabetic children and adolescent. Patients and methods: Iga antigliadin, IgG antireticulin and IgG antiendomysium antibodies were measured in 67 diabetic children (35 female), aged between 4 and 18 years old. Results : Only one male adolescent, aged years old, without gastrointestinal symptoms, had a significant elevation of antirecticulin and antiendomysium antibodies. His intestinal biopsy showed subtotal villous atrophy, consisten with celiac disease. Conclusions: The prevalence of celiac disease in these diabetic children is 1:67 (1.5 percent). Similar figures have been reported elsewhere
