Results

In patients with ulcerative colitis with erosions/ulcers (UC-UE group), CD56+/CD3+ and CD8+/CD3+ ratios were significantly lower than in the familial adenomatous polyposis (FAP) group, indicating disrupted natural killer T-cell populations. Immunohistochemical analysis showed varying lymphocyte distribution among non-inflamed mucosa, dense infiltration, and lymphoid follicles, with CD56+ cells less abundant in dense areas and HLA-DR+ cells more prevalent.

Baseline Characteristics

We prospectively analyzed endoscopic biopsy specimens from the ileal pouches of 15 patients and categorized them into three groups: FAP, ulcerative colitis with an inflammation-free pouch (UC-I), and ulcerative colitis with ulcers and/or erosions in the pouch (UC-UE).

Participant flow

We prospectively analyzed endoscopic biopsy specimens from the ileal pouches of 15 patients and categorized them into three groups: FAP, ulcerative colitis with an inflammation-free pouch (UC-I), and ulcerative colitis with ulcers and/or erosions in the pouch (UC-UE).

Adverse events

Not occurred

Outcome measures

Flow cytometry was used to assess various T-lymphocyte markers, including cluster of differentiation (CD) 4, CD8, CD56, and human leukocyte antigen (HLA)-DR. Immunohistochemistry was performed to visualize the spatial distribution of CD3+, CD56+, and HLA-DR+ cells in the pouch mucosa.
