Clinical Study on Effect of Vitamin D3 Combined With Mesalazine in Reparation of Intestinal Mucosal Oxidative Stress Injury in Patients With Ulcerative Colitis / 胃肠病学

ABSTRACT

Background: The prevalence of ulcerative colitis (UC) in China increased significantly in recent years. Vitamin D3 might be closely correlated with the development and progress of UC. Aims: To investigate the role of vitamin D3 combined with mesalazine in reparation of oxidative stress injury of intestinal mucosa in patients with UC. Methods: A total of 120 patients with mild or moderate UC from January 2019 to January 2020 at the First Affiliated Hospital of Xinjiang Medical University were enrolled, and were randomly divided into treatment group (n=60) and control group (n=60). Patients in the treatment group were treated with vitamin D3 combined with mesalazine, and patients in the control group were treated with mesalazine alone. Eight weeks after treatment, the clinical manifestations were observed. Serum oxidative stress [oxidized low density lipoprotein (ox-LDL) and lipid peroxidase (LPO)], intestinal mucosal barrier injury [serum procalcitonin (PCT) and diamine oxidase (DAO)] and Mayo score in the two groups were compared. Results: After 8 weeks treatment, the total effective rate was significantly higher in treatment group than in control group (93.3% vs. 78.3%; χ
