ABSTRACT
Objective:
To explore the significance of laboratory parameters in predicting the endoscopic manifestations of ulcerative colitis (UC) after treatment.Methods:
From January 2015 to December 2020, the clinical data of 68 patients with UC hospitalized and treated in Peking University People′s Hospital were retrospectively and continuously collected. According to the degree of bleeding, vascular pattern, erosion and ulcer under endoscopy before and after treatment, they were divided into progressive group (post-treatment ulcerative colitis endoscopic index of severity (UCEIS) score higher than pre-treatment) and non-progressive group (post-treatment UCEIS score equal to or lower than pre-treatment). The baseline platelet count, platelet volume, platelet hematocrit, platelet distribution width, serum albumin, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR) and related laboratory parameters were compared between the two groups. And analyzed the significance of related laboratory indexes in predicting the endoscopic manifestations of UC after treatment. Independent sample t test and receiver operating characteristic curve (ROC) analysis were used for statistical analysis.Results:
According to the degree of bleeding under endoscopy before and after treatment, the patients were divided into progressive group (12 cases) and non-progressive group (56 cases). The baseline platelet count and platelet volume of the progressive group were higher than those of the non-progressive group ((375.58±154.30) ×10 9/L vs. (288.22±103.76) ×10 9/L, (9.29±1.13) fL vs.(8.52±1.29) fL), and the differences were statistically significant ( t=2.40 and 2.08, P=0.019 and 0.049). According to the degree of vascular texture under endoscopy before and after treatment, the baseline platelet volume and serum albumin level of the progressive group (9 cases) were higher than those of the non-progressive group (59 cases) ((9.58±1.18) fL vs. (8.54±1.26) fL, (41.49±5.08) g/L vs. (36.63±6.14) g/L), and the baseline CRP of the progressive group was lower than that of the non-progressive group (2.26 mg/L(0.95 mg/L) vs.8.64 mg/L (26.08 mg/L) ), and the differences were statistically significant ( t=2.32, 2.32, and z=-2.27, P=0.022, 0.047 and 0.045). According to the degree of erosion and ulcer under endoscopy before and after treatment, CRP and ESR of the progressive group (16 cases) were lower than those of the non-progressive group (52 cases) ((2.21 mg/L(5.26 mg/L) vs. 10.63 mg/L(29.97 mg/L), 14.50 mm/1 h (15.25 mm/1 h) vs.17.00 mm/1 h (11.00 mm/1 h)), and the differences were statisticaly significant ( z=-3.64 and -2.42, P=0.001 and 0.020). The cutoff value of baseline platelet count to assess the progression of bleeding under endoscopy after treatment was 336×10 9/L (sensitivity=0.636, specificity=0.852, area under the curve=0.698). The cutoff value of baseline CRP to assess the progression of erosion and ulcer under endoscopy after treatment was 3.44 mg/L (sensitivity=0.750, specificity=0.727, area under the curve=0.727).Conclusions:
The baseline platelet volume, serum albumin and ESR are suggestive of endoscopic mucosal changes in patients with UC after treatment. The baseline platelet count and CRP can predict the efficacy in patients with UC.
