ABSTRACT
BACKGROUND: The association between diabetes mellitus and coeliac disease has been known for many years. In a random group of 175 insulin dependent diabetes mellitus patients of varying ages the following tests have been carried out: serum antigliadin antibodies (AGA) of IgA and IgG class, antireticulin antibodies (ARA) and antiendomisyum antibodies (AEA), both of IgA class. MATERIALS AND METHODS: The patients, 85 males and 90 females, had ages ranging from 1 yr to 30 yrs (102 in paediatric age--mainly between 6 and 14 years--and 73 adults). Patients with pathological values for AEA and/or ARA underwent an intestinal biopsy. RESULTS: Out of 175 patients studied, 21 had pathological values for AEA with or without pathological values for ARA and AGA, and 2 patients had only pathological values for ARA. 23 patients (21 with pathological values for AEA with or without ARA and AGA, 2 only for ARA ) underwent intestinal biopsy, all patients with pathological values for AEA had villous atrophy. The prevalence of coeliac disease among IDDM patients was 8.8% (95% CI 3.3 to 14.3) for the children and 16.4% (95% CI 7.9 to 24.9) for the adults. In patients with mucous atrophy, ARA, AGA IgA and IgG were pathological in 85%, 71% and 61% respectively. Symptoms and insulin requirements in all patients affected by coeliac disease before and after one year on a gluten free diet were also evaluated. The patients had clinical features with prevalently one or only few atypical symptoms which disappeared on a gluten free diet. Insulin requirements after one year on a gluten free diet appeared unchanged in coeliac patients. CONCLUSIONS: The need to screen all diabetic patients for coeliac disease is underlined.
ABSTRACT
Age of diagnosis and clinical pattern were studied in 97 celiac patients, diagnosed with jejunal biopsy, between 1976-1991. They were selected on the basis of clinical and laboratory patterns. The laboratory tests utilized were steatorrhea and xylose in the first years, while in recent years AGA, ARA and AEA were also utilized. The patients were divided into two groups, based on the year of first biopsy. The first group includes 36 cases diagnosed between 1976-1985, the second one 61 cases diagnosed between 1986-1991. In recent years an increase in the number of cases has been observed in our centre, particularly in patients over 2 years of age, while the number of diagnoses in children under 2 years of age was essentially the same. So-called typical symptoms prevailed in the first group, while so-called atypical symptoms are more frequent in the second. If an increase of incidence of celiac disease within the population is confirmed, a mass screening will be necessary in order to identify the atypical forms, utilizing laboratory tests, for the purpose of selecting patients to be subjected to an intestinal biopsy.
