Results of multicenter observational study «predictors of colectomy in patients with extremely severe ulcerative colitis

Abstract

AIM: to improve the results of treatment of patients with «extremely severe» ulcerative colitis (UC).PATIENTS AND METHODS: A multicenter observational prospective «case-control» study was conducted. The study included 71 patients with «extremely» severe UC from June 2019 to October 2021. All patients underwent conservative therapy in accordance with current clinical guidelines. Evaluation of the effectiveness of treatment was carried out on the 3rd and 7th days of therapy, a "response" or "no response" to steroid therapy was stated.RESULTS: A total of 48 (68%) patients underwent surgical treatment during the follow-up period during hospitalization. 23 (32%) patients "responded" to conservative therapy and were discharged without colectomy. A reliable independent predictor of colectomy at the time of hospitalization was the level of albumin less than 29 g/l (OR – 8,6 95% CI: 2,5 – 39,9, p=0,002). On day 3, the reliable predictors were the level of C-reactive protein over 15.5 mg/l (OR – 9 95% CI: 2.4 – 46.1, p=0.003) and the value of the Mayo index above 7 points (OR – 13.3 95% CI: 3.3 – 75.7, p=0.0009).CONCLUSION: The study has demonstrated that the only reliable and independent predictor of colectomy at admission to the clinic is the level of albumin less than 29 g/l. Reliable factors that make it possible to evaluate and predict the effectiveness of therapy are the level of C-reactive protein more than 15.5 mg/l and the value of the Mayo index above 7 points on the 3rd day of therapy, as well as the level of C-reactive protein above 29 mg/l on the 7th day.
