摘要:

目的 探究血清铜/锌、血乳酸(LA)/白蛋白(ALB)比值(LAR)联合粪便钙卫蛋白(FC)对溃疡性结肠炎(UC)病情及治疗结局的评估价值。方法 选取154例活动期UC患者并依据病情分为轻度活动组45例、中度活动组61例与重度活动组48例;另根据治疗结局分为好转组106例与未好转组48例。比较不同组血清铜/锌比值、LAR、FC等实验室指标水平,分析指标与UC患者病情及治疗结局的关系。结果 轻度活动组、中度活动组、重度活动组的血清铜/锌比值、LAR、FC水平依次升高(P<0.05);与轻度活动组比较,重度活动组血清前白蛋白(PAB)水平低(P<0.05);与好转组比较,未好转组血清铜/锌比值、LAR、FC水平高(P<0.05);Spearman相关性分析显示,UC患者血清铜/锌比值、LAR、FC水平与UC内镜下严重程度指数(UCEIS)评分呈正相关(P<0.05);多因素Logistic回归分析显示,血清铜/锌比值、LAR、FC水平升高为UC病情加重及治疗结局未好转的危险因素(P<0.05);受试者工作特征(ROC)曲线分析显示,血清铜/锌比值、LAR、FC联合评估UC病情加重及治疗结局未好转的曲线下面积(AUC)分别为0.949(95%CI:0.902~0.978)、0.936(95%CI:0.885~0.969)。结论 血清铜/锌比值、LAR、FC可作为预测病情及治疗结局的可靠生物标志物,且指标联合预测效能更佳。

Abstract:

Objective To explore the value of serum copper/zinc ratio and lactate (LA)/albumin (ALB) ratio (LAR) combined with fecal calprotectin (FC) in evaluating the condition and treatment outcome of ulcerative colitis (UC). Methods A total of 154 patients with active UC were selected and divided into the mild activity group (45 cases), the moderate activity group (61 cases) and the severe activity group (48 cases) according to their disease condition. Based on the treatment outcome, patients were divided into the improved group (106 cases) and the unimproved group (48 cases). Laboratory indices such as serum copper/zinc ratio, LAR and FC were compared between groups. The relationship between these indices and the condition and treatment outcome of patients with UC was analyzed. Results Serum copper/zinc ratio, LAR and FC levels increased in sequence in the mild activity group, the moderate activity group and the severe activity group (P<0.05). Compared with the mild activity group, serum prealbumin level was lower in the severe activity group (P<0.05). Compared with the improved group, the unimproved group demonstrated higher serum copper/zinc ratio, LAR and FC levels (P<0.05). Spearman correlation analysis showed that serum copper/zinc ratio, LAR and FC levels were positively correlated with UCEIS score in patients with UC (P<0.05). Multivariate Logistic regression analysis showed that increased serum copper/zinc ratio, LAR and FC levels were risk factors for aggravation and unimproved treatment outcomes of UC (P<0.05). The receiver operating characteristic (ROC) curve analysis showed that the areas under the curve (AUCs) of combination of serum copper/zinc ratio, LAR and FC in predicting aggravation and no improvement of UC were 0.949 (95%CI: 0.902-0.978) and 0.936 (95%CI: 0.885-0.969), respectively. Conclusion Serum copper/zinc ratio, LAR and FC can serve as reliable biomarkers for predicting the condition and treatment outcome of UC. Combined use of these indices can achieve better predictive efficacy.
