由于血液透析技术的广泛开展,慢性肾脏病(chronic kidney disease;CKD)血液透析患者的生活质量得到了明显改善,而血液透析患者的营养不良却仍然是临床医生棘手的问题,并越来越引起人们的重视,它可直接影响血透病人的临床症状、体征、并发症以及存活率等一系列问题.维持性血液透析(Maintenance hemodialysis;MHD)病人发生营养不良时,一般均可出现免疫功能降低,贫血加重,容易感染,心、脑、肺等脏器功能减退,易发生各种严重并发症,导致病人的生活质量下降,长期生存率降低,死亡率增高.营养不良不但影响维持性血液透析患者的生存期和生活质量,同时亦是并发症和死亡率增加的一个重要原因之一,探讨其原因,维持性血液透析病人营养不良的发生,既有血液透析本身的原因,也有血液透析以外的原因,本文从不同角度探讨了MHD患者营养不良的原因、影响因素以及临床上在维持性血液透析(MHD)患者营养不良方面采取的治疗对策. 相似文献

目的:通过膳食调查了解维持性血液透析患者饮食结构和膳食摄入量,评估各膳食营养素摄入量对血液透析患者营养需求的满足程度,为合理营养干预提供依据。方法:本课题以我国慢性肾脏病蛋白营养治疗共识(2005)及欧洲肠外肠内营养学会(ESPEN)的膳食指南为推荐量,采用24h膳食回顾法调查血透患者连续3d膳食摄入情况,分析食物来源和饮食结构,评价每日食物及每日营养素摄入量,比较各营养素摄入量与推荐量的差异性。结果:根据食物分类,血透患者日均摄入量排在前三位分别是蔬菜类(247.5g,占34%)、谷类(209g,占28.7%)和水果类(71.5g,占9.8%),排在末三位分别是鱼类、豆类、蛋类(13.7g,占1.9%;22.2g,占3.0%;27.6g,占3.9%);动物性食物是蛋白质摄入的主要食物来源(占62%),植物性食物是钙、铁摄入的主要食物来源(占53%和69%);与推荐量相比,血透患者除了维生素E和钠的摄入量大于推荐量外,日均总热卡和三大产热营养素(蛋白质、脂肪、碳水化合物)摄入量低于推荐量;部分维生素(维生素C、维生素B1、B2、B6)和部分矿物质(锌、硒、铁等)摄入量低于推荐量(P<0.05)。结论:血透患者普遍存在膳食摄入不足的问题,大部分膳食营养素摄入量不能满足血透患者营养需求,建议加强饮食指导和营养支持。 相似文献

Background: The purpose of the present study was to explore the association between resting metabolic rate (RMR) and protein-energy wasting (PEW) risk in Chinese hemodialysis patients by age and gender subgroup.Methods: RMR and body composition (body cell mass (BCM) and fat mass) of 774 patients undergoing hemodialysis were estimated by bio-electrical impedance analysis (BIA). Anthropometric data were collected by a standard measurement protocol, and the upper arm muscle circumference (AMC) was calculated. Biochemical nutritional and dialysis parameters were obtained. Linear regression analysis was used to analyze the relationship among RMR, body composition and nutritional factors.Results: The mean age was 54.96 ± 15.78 years. RMR level in patients was 1463.0 (1240.5, 1669.0) kcal/d. In multiple linear regression models, BCM, left calf circumference (LCC), fat mass were the determinants association with RMR (P<0.001). Among the patients in the sample, 133 (17.2%) had been diagnosed with PEW per International Society of Renal Nutrition and Metabolism (ISRNM) criteria and 363 (46.9%) were being at risk PEW. The area under the receiver-operating characteristic curve (AUC) of RMR for predicting risk PEW was greater than RMR/BCM and RMR/body surface area (BSA). When the cutoff of RMR was 1481 kcal/d it had the higher sensitivity and specificity (82 and 42%), and the AUC was 0.68 in elderly maintenance hemodialysis (MHD) patients (P<0.001). After adjustment for potential confounders, lowest RMR quartile level (<1239) increased the risk of PEW (OR = 4.71, 95% CI: 1.33–16.64, P=0.016) in all patients.Conclusions: Older patients with PEW have a lower RMR reduction. RMR and RMR/BCM may play the role in objective screening to detect risk PEW in MHD patients, especially in males. 相似文献

It has been shown recently that Selenium (Se), an essential trace element for humans, is involved in the regulation of thyroid
function, since the enzyme that catalyzes the liver conversion of the thyroid hormone T4 to the more active form T3 is a selenoenzyme.
In chronic uremic patients, low blood Se levels as well as thyroid function abnormalities are often found. The present study
was carried out to verify whether any correlation exists between Se levels and thyroid function, and to evaluate possible
changes in hormonal pattern during Se supplementation in 10 chronic uremic patients on hemodialysis (HD) treatment. Se was
supplemented orally as sodium selenite over six consecutive months. Basic plasma Se levels were significantly lower in patients
than in normal controls. Right from the start of Se supplementation, plasma Se concentration promptly normalized and leveled
off in the normal range throughout the study. Significant increase of FT3 and reduction of TSH levels were detected during
Se supplementation. In Se-supplemented patients, a significant direct correlation was also found between reverse T3 (rT3)
and TSH, and a significant inverse correlation was found between Se and TSH. Our results suggest that Se deficiency in chronic
uremic patients represents a factor influencing the thyroid function and that the Se status should be determined in the evaluation
of thyroid metabolism in these patients. 相似文献

The aim of this study was to determine if the differences observed in the levels of DNA damage in a group of patients suffering from chronic renal failure are due to differences in the repair capability. DNA damage was initially measured with the comet assay in 106 hemodialysis patients. A selected group of 21 patients representing high (ten patients) and low (11 patients) levels of DNA damage were obtained for determination of base excision repair capacity. This was measured in an in vitro assay where protein extracts from lymphocytes were incubated with a substrate of DNA containing 8‐oxoguanine, and the rate of incision was measured with the comet assay. Patients with high levels of genomic damage showed, as an average, significantly lower repair capacity (12·73 ± 1·84) in comparison with patients with low levels of genomic damage (18·13 ± 1·13). Nevertheless, the correlation coefficient between repair ability and levels of genomic damage was found to be only close to the significance value (r:?0·423, p: 0·056). Although DNA damage was clearly related to time on hemodialysis, base excision repair capacity was not. This is one of the few studies providing information on the repair capacity of chronic renal failure patients undergoing hemodialysis. As a summary, our results would indicate that DNA damage levels are in part associated to the repair capacity of the patients, and this repair capacity is not associated with the duration of hemodialysis treatment.

Zinc is necessary for growth and cells' division. Its deficiency may seriously affect antioxidant defense system and is usually related to renal failure, gastrointestinal diseases and alcoholism. It is very important to know zinc status in dialyzed patients and to prevent hypo- or hyperzincemia. Serum samples from 89 patients with chronic terminal renal failure on regular hemodialysis were withdrawn for the estimation of zinc concentrations immediately before and after dialysis. Serum zinc concentrations showed to be highly dependent on hemodialysis. In 57 (64%) patients, serum zinc concentrations decreased, sometimes from very high to normal values. In remaining 32 (36%) patients serum zinc concentrations tended to increase, but remained within normal range. Zinc supplementation may be recommended only in the patients with proven zinc deficiency, but for all chronic renal failure patients it is questionable. 相似文献

Creatol (CTL) is a product resulting from the reaction of creatinine (Cr) with the hydroxyl radical and is identified as a precursor of methylguanidine (MG), a uremic toxin. In this study, we investigated serum CTL levels together with those of Cr and MG in 66 patients who were on maintenance hemodialysis (HD). Prior to dialysis, the mean serum levels of Cr, CTL and MG were 967 (=11.1 mg/dl) ±267 μM, 11.1 ± 4.8μM and 5.8±2.9 μM, respectively. The mean CTL level was about 1.1% that of Cr, and the CTL plus MG level was about 1.4% that of the Cr level. The reduction rates of Cr, CTL and MG by a single HD were 62.6±6.1%, 71.0±10.3% and 51.9±11.6%, respectively. The CTL level at 0.5, 1 and 6h after HD increased rapidly by 20.7±8.7%, 31.7±14.7% and 80.1±27.3%, respectively. There was a significant correlation between CTL or CTL/Cr and parathyroid hormone in patients who had just undergone parathyroidectomy. No significant correlation was found between CTL or CTL/Cr and those factors which seems to be related to the predialysis levels of reactive oxygen. Therefore, because of the good clearance of CTL and its rapid conversion to MG, its usefulness for the estimation of hydroxyl radical generation in HD patients is limited. 相似文献
