Cees.kau.edu.saEffect of enteral feeding on lipid subfractions in children with chronic renal failureJameela A. Kari1, Vanessa Shaw1, David T. Vallance2, and Lesley Rees11 Nephrourology Unit, Great Ormond Street NHS Trust, London WC1N 1EH, UK 2 Department of Biochemistry, Royal Free Hospital and School of Medicine, Hampstead, London NW3, UK Received August 19, 1997; received in revised form December 19, 1997; accepted January 2, 1998 Abstract. The anorexia of chronic renal failure (CRF) is (LDL), apoprotein B (apo B) and lipoprotein(a) [Lp(a)], frequently managed with enteral feeds using combinations and reduced high-density lipoprotein (HDL), apo A1 and of commercial preparations, glucose polymers and fat apo A2 , all of which are believed to predispose to emulsions. Such feeds might predispose to atherogenic atherosclerosis. Studies in children have demonstrated blood lipid profiles. Our aim, therefore, was to compare the similar findings, but with a higher incidence of hypercho- blood lipid profiles of enterally fed and non-enterally fed children. Plasma lipid subfractions were measured in As well as the metabolic effects of CRF, the blood lipid 37 children with CRF managed conservatively and 10 profiles of patients may be influenced by their diet. High managed with peritoneal dialysis (PD); 10 of the children intakes of saturated fatty acids (FAs) increase serum LDL were tube fed, 5 of whom were on PD. Results were and TGs. Polyunsaturated FAs reduce LDL, but at the same compared between these groups.

High intakes of refined carbohydrate (CHO) increase density lipoprotein (HDL), apoprotein A1 (apo A1), A2 (apo A2) and B (apo B), and lipoprotein (a) [Lp(a)] were It is our policy to institute early enteral feeding in within the normal range. There was an inverse correlation children with CRF with a declining growth velocity. Such between TGs and glomerular filtration rate (P = 0.0001).

We conclude that enteral feeding does energy sources. The children eat little or no complex CHO or non-starch polysaccharides (fibre), so most of their in- take of CHO is refined. We were concerned, therefore, that Key words: Chronic renal failure ± Lipids ± Lipoproteins ± while providing adequate nutrition for growth, tube feeding regimens might have an adverse effect on the blood lipid Our purpose was to study the lipid profiles of children attending our CRF clinic who were eating a high-energy, low-phosphate, but otherwise unrestricted diet and to compare the results with those of a group of children who were receiving at least 50% of their energy as an enteral Hyperlipidaemia is one of the factors believed to be re- sponsible for the high incidence of atherosclerosis in chronic renal failure (CRF) . Abnormalities of lipids and lipoproteins reported in CRF include: increased triglycer- ides (TGs), total cholesterol (TC), low-density lipoprotein Patients. Forty-seven children (32 boys) aged 1±17 years [mean 9.3+5.2 (SD)] with CRF [defined for the purposes of this study as a Correspondence to: J. A.

Older children were fasted overnight prior to blood sampling, but younger children were fasted for at least 4 h (although they were allowed water). This length of time has been used in other large studies . Serum TC, TG, LDL, HDL, apo A1, apo A2, apo B and Lp(a) and Lipid subfractions were compared between the four patient groups (Table 2) using analysis of variance. Analysis of covariance (AN- COVA) was used to adjust for age and creatinine when a significant difference was found between groups. A significant P value was defined as 50.05. Each subject and/or their parents gave informed consent to the study, which was approved by the local committee on Methods. TC was measured using the cholesterol C system high-per- formance cholesterol oxidase 4-aminophenazone method and TG by FA, Fatty acid; trans, transpolyunsaturated FA glyceryl phosphate oxidase 4-aminophenazone high-performance en- zymatic colorimetric test (both Boehringer Mannheim Diagnostica) b Dietary reference values for food energy and nutrients for the United . HDL was measured following precipitation of apo B-containing lipoproteins and LDL was calculated using the Friedewald formula .

whom were enterally fed (Table 1). The mean (range) glomerular fil- tration rate (GFR) of the medically managed children was 15 (5±35) ml/min per 1.73 m2. Children with nephrotic syndrome were excluded because of its effect on lipid metabolism .
The mean (range) length of time on enteral feeds was 18.2 (6±32) months. The feeds were prepared from whey-based infant formulae or Children who were managed medically and on PD without cows' milk protein-based adult enteral feeds, and were delivered by enteral feeds (groups 1 and 2) were older than the enterally pump overnight. One child received a soya-based feed because of fed children. Medically managed children were taller, but parental suspicion of cows' milk protein intolerance. One received a there was no difference in body mass index among the four whey hydrolysate to enhance stomach emptying. All feeds included a comprehensive range of vitamins and minerals. The aim was to offer adequate nutrition for growth, while maintaining blood chemistry The results of the lipid subfractions are shown in Table 1.

Figure 1 illustrates the average requirement for energy for chronological age using additional relationship between serum TGs and method of feeding, glucose polymers and peanut oil emulsions, and reference nutrient plasma creatinine and treatment modality. There was an intake for protein for height age (dietary reference values, Table 2).
overall positive correlation between TGs and creatinine Table 2 shows the tube feed composition for protein, CHO and FAs, and the corresponding United Kingdom recommended dietary (r = 0.63, P 50.0001). However, there was no difference intakes for a healthy population. Also shown are the observed dietary among the patient groups when the results were corrected intakes of British adults (comparable figures are not available for for age and creatinine (ANCOVA P = 0.07). There was also children). The dietary intake of the non-tube-fed children was not a negative correlation between TGs and GFR in children in However, we achieved a balanced energy intake with our enteral formula composition, which did not differ sig- nificantly from published recommendations for dietary in- take for a normal population. Indeed, the total fat intake, and particularly the saturated fat intake, was less in the tube-fed children than in a normal adult population eating an unrestricted diet (Table 2). Despite a CHO intake comprised mainly of refined sugars rather than a mixture of sugars, starch and fibre, there was no adverse effect on Although the children were under regular dietary re- view, we were not able to fully analyse the intakes of those who were not tube fed because there are only a few foods that have been analysed for their FA composition. As these children were eating a relatively free diet rather than re- ceiving a precisely prescribed enteral feed, it is possible that their diet was less balanced than that of the tube-fed It might be expected that the glucose load during PD Fig. 1.

Although the patients on PD were the only group to have levels of atherogenic lipids above the normal range, those on PD group 1 (P = 0.0001), even when age was taken into con- who were enterally fed did not. One possible explanation is that the enteral feed was beneficial to the plasma lipids, but Children managed by PD (group 3) were the only group the numbers are too small to draw any conclusions.

The importance of that were above the normal range, although TC levels were TGs in atherogenesis is controversial, but recently it has at the upper limit of normal in the other groups.
