摘要:

目的 探究肠外营养治疗患者血清水溶性维生素异常升高的影响因素。方法 纳入接受营养诊疗的住院患者862例,监测每日水溶性维生素供给量及总尿量;若患者行肾替代治疗,则记录超滤量。检测9种水溶性维生素(Vit-C、B1、B2、B3、B5、B6、B7、B9、B12)水平。根据检测结果将患者分为维生素蓄积组与非蓄积组,比较2组肾功能指标[血尿素氮(BUN)、肌酐(Cr)、尿酸(UA)、尿量],炎性指标[C反应蛋白(CRP)、白细胞计数(WBC)、中性粒细胞计数(NEU)、系统免疫炎症指数(SII)],营养指标[白蛋白(ALB)、前白蛋白(PA)、血红蛋白(Hb)、淋巴细胞计数(LYM)]。采用Logistic回归分析水溶性维生素循环蓄积的影响因素。结果 Vit-B2、B6、B5的蓄积发生率较高,分别为36.08%、16.01%和13.81%。与非蓄积组相比,Vit-B2蓄积组年龄偏大,BUN、Cr、UA、NEU水平升高,ALB、PA和尿量降低;Vit-B5蓄积组BUN、Cr、UA、NEU水平升高,LYM、Hb、ALB、PA、尿量降低;Vit-B6蓄积组年龄偏大,BUN、Cr、UA水平升高,LYM、Hb、ALB、尿量、维生素供给量降低(P<0.05)。多因素Logistic回归分析显示,血BUN水平升高是Vit-B2蓄积的独立危险因素,血BUN水平升高及尿量减少是Vit-B5蓄积的独立危险因素,血BUN、Cr升高及尿量降低是Vit-B6蓄积的独立危险因素。受试者工作特征曲线分析示,BUN预测Vit-B2、B5、B6蓄积的曲线下面积分别为0.659(95%CI:0.620~0.697)、0.728(95%CI:0.675~0.781)、0.785(95%CI:0.738~0.831),其特异度较高,敏感度较低。结论 血清水溶性维生素水平受肾功能影响,实施肠外营养水溶性维生素补充时应评估患者肾功能状态,并警惕Vit-B2、B5、B6异常升高的风险。

Abstract:

Objective To explore the influencing factors of abnormal increase of plasma water-soluble vitamins in patients with parenteral nutrition (PN). Methods A total of 862 hospitalized patients receiving nutritional diagnosis and treatment were enrolled. Daily water-soluble vitamin supply and total urine output were monitored. If patients underwent renal replacement therapy (RRT), the ultrafiltration volume was recorded. Plasma concentrations of nine water-soluble vitamins (Vit-C, B1, B2, B3, B5, B6, B7, B9 and B12) were measured. According to the test results, patients were divided into the accumulation group and the non-accumulation group. Renal function (BUN, Cr, UA), inflammatory indicators (CRP, WBC, NEU, SII) and nutritional indicators (ALB, PA, Hb, LYM) were compared between the two groups. Logistic regression was used to analyze the independent risk factors for the accumulation of water-soluble vitamins. Results There was a high incidence of abnormal plasma water-soluble vitamin levels, including Vit-B2 (36.08%), Vit-B6 (16.01%) and Vit-B5 (13.81%). Compared with the non-accumulation group, the Vit-B2 accumulation group had higher levels of age, BUN, Cr, UA and NEU, and lower levels of ALB, PA and urine volume. The Vit-B5 accumulation group had higher levels of BUN, Cr, UA and NEU, and lower levels of LYM, Hb, ALB, PA and urine volume. Patients in the Vit-B6 accumulation group was older, with increased levels of BUN, Cr and UA, and decreased levels of LYM, Hb, ALB, urine volume and vitamin intake (P<0.05). Multivariate Logistic regression analysis showed that the elevated level of BUN was independent risk factors for Vit-B2 accumulation, the elevated BUN and reduced urine volume were independent risk factors for Vit-B5 accumulation, and elevated BUN and Cr, as well as reduced urine volume, were independent risk factors for Vit-B6 accumulation. Receiver operating characteristic curve analysis showed that the area under the curve for BUN in predicting Vit-B2, B5 and B6 accumulation were 0.659 (95%CI: 0.620-0.697), 0.728 (95%CI: 0.675-0.781) and 0.785 (95%CI: 0.738-0.831), respectively, with high specificity but low sensitivity. Conclusion The serum levels of water-soluble vitamins are affected by renal function. When implementing parenteral nutrition water-soluble vitamins supplementation, the patient's renal function status should be evaluated, and the risk of abnormal elevation of Vit-B2, B5 and B6 should be vigilantly monitored.
