P006 The Relationship of Histological Remission With the Duration of the Anamnesis Ulcerative Colitis.

Abstract

The objectives of the treatment of patients with ulcerative colitis (UC) in accordance with the STRIDE-I provision, involves endoscopic healing of the colon mucosa. Histological remission is associated with endoscopic healing, which can be a predictor of long-term results. Biological and cellular therapy is most effective in the early stages of the disease. To assess the depth of histological remission with the duration of UC. The biopsy material of 75 patients with total or left-sided UC of moderate severity and severe severity aged from 22 to 56 years (average age 31 ± 2.5 years), who were divided into groups depending on the therapy, was studied. The first group of patients with UC aged 22 to 51 years (Me-32) (n = 29) received anti-inflammatory therapy using mesenchymal stromal cell culture (MSCs) 2 million/kg; the second group of patients with UC (n = 27) aged 24 to 56 years (Me-38) received vedolizumab (VDB) according to the recommended scheme, the third group of patients with UC (n = 19) aged 27 to 52 years (Me-31) received MSCs+VDB. The achievement of histological remission was assessed by the score of Geboes (SG). In 1st group, patients who achieved histological remission (SG1) with a disease duration of more than 5 years - 14 (48.3%) patients, less than 5 years - 5 (17.2%) (95% CI 1.256 - 19.293; x2-7.635; p = 0.006). In the 2nd group of patients who achieved histological remission (SG1) with a disease duration of more than 5 years - 15 (55.5%) patients, less than 5 years - 4 (14.9%) (95% CI 1.262 - 20.615; x2-7.026; p = 0.009). In the 3rd group of patients who achieved histological remission (SG1) with a disease duration of more than 5 years - 4 (21.1%) patients, less than 5 years - 7 (36.8%) (95% CI 1.080 - 138.995; x2-4.968; p = 0.026). A statistically significant majority of patients who achieved histological remission, regardless of the therapy, had a disease duration of less than 5 years.
