Objective: To assess PEW in predialysis patients on their first visit to a nephrologist. Methods: Three day dietary intake of 484 CKD stage 3 patients was taken. Appetite was assessed with ADAT. Patients were divided into groups based on appetite and BMI. Results: Male and female parameters are serum albumin 3.7 ± 0.84/3.68.8 ± 0.81 g/dL, total protein 7.02 ± 1.27/6.94 ± 1.26 g/dL, creatinine 4.68 ± 4.19/3.74 ± 3.36 mg% creatinine clearance 33.22 ± 30.48/37.55 ± 33.87 ml/minute, BMI 22.60 ± 4.29/23.43 ± 4.77kg/m2 energy/kg 16.97 ± 0.65/16.8 ± 0.64, protein g/kg 0.65 ± 0.28/0.64 ± 0.30, carbohydrate g/kg 2.98 ± 1.54/2.98 ± 0.1.36, fat g/kg 2.98 ± 0.23/2.79 ± 0.22, respectively. As appetite decreased, dietary protein and energy intake decreased significantly. Appetite in males and females: Average 14.46%, 4.13%, poor 9.7%, 18.18%, anorexic 13.2%, 7.4%. Income had strong correlation with BMI (p 0.000), dietary protein (p 0.000), energy (p 0.000) and carbohydrate (p 0.000). Appetite correlated with creatinine (p 0.019), dietary energy, protein, carbohydrate and fat (p 0.000) intake. BMI correlated (p 0.000) with fat, carbohydrate, energy and creatinine clearance. ANOVA showed significant difference within and between appetite groups in energy, protein, fat, carbohydrate, creatinine clearance (p 0.000) and serum albumin (p 0.025). There was significant difference in protein (p 0.026), energy intake (p 0.000) and creatinine clearance (p 0.038) within and between BMI groups. Based on income, there was significant difference among groups in BMI (p 0.000), energy (p 0.019), protein (p 0.031) and albumin (0.001).展开更多

We previously proposed a new and simple protein-energy wasting (PEW) score that appears to be useful for assessing the risk of mortality in patients on MHD. <strong>Objectives: </strong>In the present study, we evaluated the reliability of this PEW score as a predictor of hospitalization in Japanese patients on MHD. <strong>Methods:</strong> In this single-center, prospective cohort study conducted in Japan, PEW score was calculated for 180 MHD patients. PEW score ranged from 0 (best: S1) to 4 (worst: S4) and was calculated based on nutritional indicators including serum albumin, body mass index, serum creatinine level, and protein intake. The outcome was the number of hospitalizations during the 2-year study period. <strong>Results:</strong> Thirty-six patients were hospitalized during the study period. Kaplan-Meier curves showed there were fewer hospitalizations in the group with a PEW score of 0/1 than in the group with a score of 3/4. Multivariate analysis revealed a hazard ratio for hospitalization of 3.109 for S3/4 versus S0, 2.777 for S3/4 versus S1, and 2.048 for S3/4 versus S2.<strong> Conclusion:</strong> The new and simple PEW score is a useful predictor of hospitalization in MHD patients and is also useful for identifying subgroups of MHD patients with a high risk of mortality.展开更多

文摘目的调查维持性血液透析(maintenance hemodialysis,MHD)患者蛋白质能量消耗(protein-energy wasting,PEW)状况及PEW对生活质量的影响。方法选取多个中心MHD患者205例随访,通过实验室检查、人体测量、人体成分分析、标准化蛋白代谢率(nomalized protein catabolic rate,nPCR)评价PEW状态,应用肾病及生活质量问卷(kidney disease and quality of life^(TM),KDQOL^(TM)-36)评估患者生活质量,分为PEW组和非PEW组进行统计分析。结果 194例MHD患者,40例诊断为PEW;PEW组患者肌肉组织指数、人体细胞质量、上臂肌肉围径、握力均低于非PEW组;Logistic回归分析示C反应蛋白(C-reactive protein,CRP)为PEW的危险因素[OR=1.064,95%CI(1.023,1.109),P=0.001],sp Kt/V>1.2、nPCR>0.8g/(kg·d)为PEW的保护因素[OR=0.638,95%CI(0.430,0.954),P=0.029;OR=0.017,95%CI(0.005,0.059),P<0.001];PEW组KDQOL^(TM)-36 11个维度得分均低于非PEW组,其中总体健康(t=2.432,P=0.018)、社会情感(t=2.510,P=0.012)、精力体力(t=2.361,P=0.020)、症状影响(t=3.337,P=0.001)4个维度得分显著低于非PEW组。结论郑州市MHD患者PEW患病率为20.6%,PEW的特征可能是肌肉组织的消耗,饮食摄入、透析充分性、炎症状态是PEW的影响因素,PEW影响患者的生活质量。
