Objective: To determine the incidence and presenting features of adult coeliac disease in a single university hospital in South Yorkshire.Design: A retrospective case finding study. Data were obtained from pathology and immunology databases, clinical notes, dietetic records, and patient questionnaires.Setting: Royal Hallamshire Hospital in South Yorkshire, England.Participants: All recorded cases of coeliac disease.Main Outcome Measures: Crude annual incidence rates for coeliac disease was obtained. The numbers of coeliac antibody profiles requested per year from the Royal Hallamshire Hospital were ascertained. Age at diagnosis, sex, year of diagnosis, presenting symptoms, associated conditions, and delay in diagnosis was documented. In addition the specialty of the clinician who made the diagnosis was noted.Results: There were 264 cases in total (male n=86, ratio 1:2). Mean age at diagnosis was 44.9 years (range 1-82, median 44.5). A trend was observed from 1990 to 2000 inclusive, of an annual increase in the incidence of coeliac disease. There has been a coincidental increase in the measurement of associated antibodies. Although 28.4% of patients presented with gastrointestinal symptoms, 20.1% had iron deficiency anaemia. The ratio of typical to atypical symptoms was 1:2.5. (single sample test of proportions p<0.001). The diagnosis was made by a gastroenterologist in only 52.7% of cases. The median duration of symptoms before the diagnosis of coeliac disease was 4.9 years (range 0.25-16 years).Conclusion: Coeliac disease is now presenting more commonly without gastrointestinal symptoms and often to specialties other than gastroenterology. Although more cases are diagnosed, this may be a reflection of increasing recognition rather than a true increase in incidence. [ABSTRACT FROM AUTHOR]

Background & Aims: The clinical effects of gluten-sensitive enteropathy with villous atrophy limited to the duodenal bulb (D1) have not been delineated in adults with celiac disease. We investigated the sensitivity of D1 biopsy analysis in the detection of celiac disease, the number and sites of biopsies required to detect ultra-short celiac disease (USCD, villous atrophy limited to D1), and the clinical phenotype of USCD., Methods: We performed a prospective study of 1378 patients (mean age, 50.3 y; 62% female) who underwent endoscopy at a tertiary medical center in the United Kingdom from 2008 through 2014; routine duodenal biopsy specimens were collected from D1 and the second part of the duodenum (D2). Quadrantic D1 biopsy specimens were collected from 171 consecutive patients with a high suspicion of celiac disease (mean age, 46.5 y; 64% female). Clinical data from patients diagnosed with USCD, based on biopsy analysis, were compared with those from patients with conventional celiac disease (CCD) (villous atrophy beyond D1) and individuals without celiac disease (controls). The number of intraepithelial lymphocytes (IELs) and immune phenotypes were compared between D1 vs D2 in patients with celiac disease., Results: Of the 1378 patients assessed, 268 (19.4%) were diagnosed with celiac disease; 9.7% of these patients had villous atrophy confined to D1 (USCD; P < .0001). Collection of a single additional biopsy specimen from any D1 site increased the sensitivity of celiac disease detection by 9.3%-10.8% (P < .0001). Patients with USCD were younger (P = .03), had lower titers of tissue transglutaminase antibody (P = .001), and less frequently presented with diarrhea (P = .001) than patients with CCD. Higher proportions of patients with CCD had ferritin deficiency (P = .007) or folate deficiency (P = .003) than patients with USCD or controls. Patients with celiac disease had a median of 50 IELs/100 enterocytes in D1 and a median of 48 IELs/100 enterocytes (P = .7) in D2. The phenotype of IELs from patients with D1 celiac disease was indistinguishable from those of patients with D2 celiac disease., Conclusions: Collection of a single additional biopsy specimen from any site in the D1 intestine increases the sensitivity of detection for celiac disease. Patients with USCD may have early stage or limited celiac disease, with a mild clinical phenotype and infrequent nutritional deficiencies., (Copyright © 2016 AGA Institute. Published by Elsevier Inc.

Objectives: To establish the prevalence of coeliac disease in the general population and in specific conditions, such as irritable bowel syndrome, iron deficiency anaemia, fatigue and other coeliac-related conditions., Methods: Primary-care-based cross-sectional study using immunoglobulins, IgA/IgG antigliadin antibodies and endomysial antibodies to initially recognize coeliac disease. A total of 1200 volunteers were recruited from January 1999 to June 2001 from five general practices in South Yorkshire, UK. Any participant with a positive IgA antigliadin antibody, positive endomysial antibody, or only IgG antigliadin antibody in the presence of IgA deficiency was offered a small-bowel biopsy to confirm the diagnosis of coeliac disease., Results: Twelve new cases of coeliac disease were diagnosed from 1200 samples. The prevalence of coeliac disease in this primary care population sample is 1% (95% CI 0.4-1.3%). The prevalence of coeliac disease was 3.3% (4/123) in participants with irritable bowel syndrome, 4.7% (3/64) in participants with iron deficiency anaemia, and 3.3% (3/92) in participants with fatigue., Conclusions: This study describes the prevalence of undiagnosed adult coeliac disease in primary care patients with irritable bowel syndrome, iron deficiency anaemia and fatigue. Underdiagnosis of coeliac disease is common in primary care. A case-finding approach would avoid delays in diagnosis and the associated morbidity or potential complications of coeliac disease. A low threshold for serological screening of patients with coeliac-associated symptoms or conditions would be an optimal strategy.
