Histological sections were also immunostained with CD4, CD20 and HLA-DR to determine the nature of the inflammatory infiltrate.Results 15 SDS cases were included, 7 (47%) of which showed morphologically normal duodenal villous architecture, whereas 8 (53%) showed varying degrees of enteropathic histological features ranging from villous blunting to partial villous atrophy and duodenitis. 11/15 (73%) showed some degree of duodenal inflammation, including increased lamina propria density of plasma cells, macrophages and eosinophils.Conclusion Varying degrees of duodenal inflammatory enteropathic features are present in more than 50% of symptomatic children with SDS. This suggests that, in addition to pure pancreatic exocrine failure, an enteropathic component may contribute to symptoms in some cases, and be potentially responsive to appropriate therapy.
