In contrast, a large population study by Elfström et al. found a positive association between CeD and pancreatic cancer during the first year of follow-up among patients with biopsy-confirmed CeD, inflammation, or latent CeD (normal mucosa but positive TGA IgA, EMA IgA, or tissue transglutaminase test at the time of biopsy). This evidence concerns the gene CD79A and familial pancreatic carcinoma.
