Abstract:
Objective To explore the clinical characteristics and medicine treatment of patients with severe ulcerative colitis (UC),the efficacy of rescue treatment in patients with glucocorticoid (GCS) resistant severe UC,and the clinical risk factors in patients with GCS-refractory severe UC.Methods From January 2001 to December 2012,clinical,laboratory,endoscopy,imaging data and medication of treatment of 106 patients with severe UC were retrospectively analyzed.Then the patients were followed up,and the clinical efficacy and under endoscopic presentation of Mayo score were evaluated.Logistic regression analysis was performed to analyze the high risk factor of GCS-refractory severe UC.Results Among 106 patients with severe UC,95 were chronic relapse type accounting for 89.6 ％.The percentage of patients with defecation times over six was 73.6％ (78/106),with severe purulent bloody stool was 51.0％ (54/106),and with moderately or severe abdominal pain was 83.0％ (88/106).The percentage of diffuse colon type was 83.0％ (88/106),endoscopic presentation of Mayo score over two was 87.7％ (93/106).Hemoglobin decreased in 65.1％ (69/106) patients,blood platelet increased in 48.1％ (51/106) patients,C-reaction protein elevated in 88.7％ (94/106) patients,and hypoalbuminemia decreased in 42.5％ (45/106) patients.Account to 89.6％ (95/106) of patients with severe UC received GCS treatment,and the percentage of induced remission was 64.2％ (61/95),effective rate was 16.8％ (16/95),and ineffective rate was 18.9％ (18/95).The percentage of GCS refractory was 35.8％(34/95).There were 23 patients with GCS resistance and 11 patients with GCS dependence.Ten patients with GCS resistant severe UC accepted medicine rescue therapy.Five cases were treated with cyclosporin A,of which two cases induced remission,one case was effective,and two cases were ineffective.Another five cases were treated with infliximab,of which three cases induced remission,and two cases were ineffective.The results of Logistic regression analysis showed that severe anemia (OR=6.750,95％CI:2.656 to 17.152,P＜0.01),elevated blood platelets (OR=4.032,95％CI:1.226 to 13.261,P=0.015) and albumin level less than 25 g/L (OR =3.022,95 ％ CI:1.236 to 7.390,P =0.022) were risk factors of GCS-refractory severe UC.Conclusions GCS resistant or dependent occurred in part of patients with severe UC.Patients with G-CS resistant severe UC receive rescue treatment of cyclosporin A or infliximab.Severe anemia,elevated blood platelets,albumin less than 25 g/L may be clinical predicting factors in patients with GCS-refractory severe UC.
