Abstract

Background
In patients with ulcerative colitis, histological healing is associated with better clinical outcomes1. Therefore,histological remission as the treatment target is advocated. observational studies2,3 have shown that patients in endoscopic, histological remission have longer relapse-free survival, reduced hospitalization rates, corticosteroid use rates.

Methods
Demographic information, laboratory findings, clinical courses of patients with ulcerative colitis who had disease clearance, were evaluated retrospectively for 5 years. The files of 529 patients with ulcerative colitis were scanned, patients who had not achieved disease clearance, had a history of surgery, were not followed regularly, were &lt;5 years old were excluded. 87 patients were included in this study. The validated Nancy histological index was used to assess histological disease activity.

Results
A total of 87 patients with Ulcerative Colitis, 51 of whom were male. The mean age was 54.1±13.5 years. The mean age of the patients at diagnosis was 38.9±13.6 years. The mean follow-up period was 14.5±7.7 years. The mean disease age was 15.6±7.8 years. Only 1 patient had a family history. 5 (5.7%) patients had pANCA positivity. 14 (16%) patients had extraintestinal involvement (ankylosing spondylitis, erythema nodosum, sacroiliitis, arthritis, uveitis). Current disease involvement was E1 in 11 (12.6%) patients, E2 in 45 (51.7%) patients, and E3 in 31 (35.7%) patients. Mayo endoscopic subscore was 0 in 45 (51.7%) patients; Mayo endoscopic subscore was 1 in 42 (48.3%) patients. In maintenance treatment, 50 (57.5%) were receiving only oral/topical 5-ASA, 37 (42.5%) were receiving azathioprine and 5-ASA combination. Remission was achieved in 72 (82.8%) patients with conventional treatment, and only 15 (17.2%) were receiving biological treatment. During the course of the disease, 29 (33.3%) patients required ≥1 steroid. No attacks were observed in 69 (79.3%) patients in the last 5 years. The rate of achieving remission was found to be 16% in 529 patients.

Conclusion
Although the rate of achieving deep remission in ulcerative colitis is low, remission rates are high in patients with rectal or left colon involvement at the time of diagnosis.
