Abstract
We report hyperamylasemia due to macroamylasemia in a 33-year-old-woman with gluten enteropathy. Macroamylasemia was demonstrated by precipitation of 97% of amylase activity with PEG 6000. It was associated with increased serum IgA, with elevated values of specific IgA antibodies against α-gliadin and with a high titre of IgA anti-endomysium antibodies. Macroamylasemia disappeared after 2 months of a strict gluten-free diet. These data suggest that the increased IgA concentration in adult gluten enteropathy led to increased macroamylase formation.
