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.
