          Abstract

          Coeliac disease is more prevalent in individuals with type 1 diabetes mellitus than in the normal population. It often presents in an atypical or silent form. Specific autoantibodies are found in almost all cases. Untreated coeliac disease may be associated with long-term health risks, so screening and early treatment with a gluten-free diet seem to be justified. However, extended follow-up is needed to document the clinical benefits of screening and treatment in diabetic patients.

          Celiac disease risk in the USA: high prevalence of antiendomysium antibodies in healthy blood donors.

          Recent epidemiologic studies in Europe using antigliadin (AGA) and anti-endomysium antibodies (AEA) for initial screening have shown that the overall prevalence of celiac disease (CD) is about 1:300. There are no comparable scientific data for the USA, where CD is considered rare. The main aim of this study was to determine the prevalence of increased AEA in healthy blood donors in the USA. Sera from 2000 healthy blood donors were screened for IgG AGA and IgA AGA with an enzyme-linked immunosorbent assay test. All those with increased AGA levels, those with intermediate levels, and random samples with low levels were tested for AEA, using both monkey esophagus (ME) and human umbilical cord (HUC) cryosections as substrates. The mean age of the blood donors was 39 years, with 52% being men, 85.2% being Caucasian, 11.8% African-American, 1.5% Asian, and 1.5% Hispanic. Eight healthy blood donors had positive AEA tests on both monkey esophagus and human umbilical cord. Among the eight subjects with increased AEA levels seven were Caucasian and one was African-American. All the four examined AEA-positive donors carried the known susceptibility alleles for CD. The prevalence of increased AEA levels in healthy blood donors in the USA is 1:250 (8:2000). This is similar to that reported in countries in Europe, where subsequent small-intestinal biopsies have confirmed CD in all those with AEA positivity. On the basis of a high positive predictive value of the AEA antibody test, it is likely that the eight blood donors identified in this study have CD. These data suggest that CD is not rare in the USA and that there is need for a large-scale epidemiologic study to determine the precise prevalence of the disease in the USA.

              Coeliac disease in children and adolescents with IDDM: clinical characteristics and response to gluten-free diet.

              A total of 167 children and adolescents with insulin-dependent (Type 1) diabetes mellitus (97 males; age range 1.9-22.4 yrs) in a UK paediatric diabetic clinic were screened for coeliac disease using the IgA endomysial (EMA) test, or, in IgA deficient subjects, the IgG antigliadin (AGA) test. Antibody positive subjects were selected for small bowel biopsy, and confirmed coeliac cases started on a gluten free diet. Clinical features, height (Ht) standard deviation score (SDS), body mass index (BMI) SDS, HbA1c, insulin requirements' haemoglobin (Hb), mean red cell volume (MCV), serum folate and ferritin levels were evaluated at diagnosis and thereafter at 3-6 month intervals. A total of 156 subjects (93.4%) were antibody negative. Eleven (6.6%) were antibody positive (10 EMA/1 AGA; 6 males), of whom 9 had biopsies: 1 normal: 8 coeliac (4.8%; 5 males; 1 'classical'; 1 anaemia; 3 'atypical'; 3 asymptomatic). Seven coeliac subjects were followed during 12-24 months of dietary therapy. Pretreatment mean (range) Ht SDS = 0.08 (-1.66 to 1.88); BMI SDS = 0.32 (-0.82 to 1.29); HbA1c = 8.9 (6.2 to 11.3%); insulin dose = 0.98 (0.51 to 1.29) U kg(-1) day(-1). During treatment antibody status reverted to and remained negative, and symptoms resolved. By 24 months, there was a trend towards increased BMI SDS (mean (range) 1.31 (0.47 to 2.29), p = 0.248) and to reductions in HbA1c (8.1 (6.4-10.8), p = 0.697). Repeat small bowel biopsies were normal in 6 subjects (1 refused). No statistically significant changes occurred in any other parameters. In conclusion, serological screening is effective, although the therapeutic benefit of dietary therapy in asymptomatic cases remains uncertain.
