Prevalence of coeliac disease in healthy blood donors: A study from north India

Background: Blood donor screening can help predict prevalence of coeliac disease in population. Methods: Between December 2010 and June 2011, healthy blood donors were screened using anti-tissue glutaminase antibodies. Those positive underwent duodenoscopy. Their age, gender, body mass index and haemoglobin and histological changes were recorded. Results: Of the 1610 blood donors screened, 1581 (98.2%) were males. The mean age of donors was 31.51 +/- 9.66 years and the mean body mass index was 22.12 +/- 4.24 kg/m(2). Nine (0.56%) men were seropositive. Endoscopic features included reduced fold height (9), scalloping (8), grooving (7) and mosaic mucosal pattern (3). Eight had Marsh IIIa changes whilst one had IIIb change. The prevalence of coeliac disease was 1:179 (0.56%, 95% confidence interval 1/366-1/91, 0.27-1.1%). None of the 9 patients had any symptoms. Their mean haemoglobin and body-mass index was similar to rest of the cohort. Conclusion: The prevalence of coeliac disease amongst apparently healthy blood donors was 1:179(0.56%).
