By comparing the signs of inflammation and the degree of hyperplasia of the enterochromaffin cells ( EC ) in duodenal biopsies obtained from patients with presumed post - infectious functional dyspepsia ( PI - FD ) and unspecified - onset functional dyspepsia ( U - FD ) , they showed that PI - FD is associated with persistence of focal T - cell aggregates , decrease in CD4 + cells and increased macrophage counts surrounding the crypts , without any significant differences in the numbers of EC or chromogranin A ( CA ) - positive cells ( mast cells ) .
