Figure 1 The spectrum of small intestinal damage in the study groups. Hematoxylin and eosin stained biopsy specimens obtained by gastroscopy. A: Normal duodenal mucosa: normal villus-to-crypt ratio; intraepithelial lymphocytes (IEL) within the normal range; B: Marsh 1: lymphocytic enteritis (an increase in IEL count); C: Marsh 3a: partial villous atrophy with hypertrophic crypts and an increase in IEL count; D: Marsh 3b: subtotal villous atrophy with hypertrophic crypts and an increase in IEL count; E: Marsh 3c: total villous atrophy with hypertrophic crypts and an increase in IEL count.
