To determine whether anthropometry mightbe an acceptable intermediate outcome in nutri-tion intervention trials. If sufficient energy intake to maintain nutri-tional status cannot be attained by these tech-niques, supplemental tube feeding may be consid-ered. Adapted and reprinted with permission from Durnin and Womersley. Assessment of nutrient in-take is essential for assessing the probability thata patient will develop PEM, for evaluating thecontribution of inadequate nutrient intake to ex-isting PEM, and for developing strategies toimprove protein-energy nutritional status. Because evidence of protein-energy malnutrition may develop beforeindividuals require renal replacement therapy, regular monitoring eg, at 1-to 3-month intervals of the patients nutritional status should be a routinecomponent of the care for the patient with CRF. Acutely ill maintenance hemodialysis patients should receive at least 1.
Inaddition, DOQI has spawned numerous educa-tional and quality improvement projects in virtu-ally all relevant disciplines, as well as in dialysistreatment corporations and individual dialysiscenters. The tech-nique for the measurement of TNA is expensive,labor intensive, and impractical for routine clinicaluse. English language articlesfor which the abstracts were selected were thenobtained and categorized based on the clinicalquestion the article addressed. In theclinically stable patient, PNA can be used toestimate protein intake. Because acutely ill MD patients are generallyvery inactive physically, their energy needs willbe diminished by the extent to which their physi-cal activity has been decreased. Following a series of nationwide town hallmeetings held to obtain input into the recommen-dations made at the Consensus Conference, theNKF issued an Evolving Plan for the Contin-ued Improvement of the Quality of DialysisCare in November In addition, theWork Groups referred articles for review,and the Sigma Tau Pharmaceutical Corporationsubmitted a bibliography that contained ad-ditional references that were included in theanalysis. The change in the body creatinine pool whenbody weight varies can be calculated from thefollowing equation:.
Acutely ill chronic peritoneal dialysis patients should receive at least 1. Although occasionally a physician, nurse, orother individual may possess the expertise andtime to conduct such activities, a registered dieti-tian, trained and experienced in renal nutrition,usually is best qualified to carry out these tasks.
To achievethese objectives, it was decided to adhere toseveral guiding principles that were consideredto be critical to that initiatives success. Vje was complete agreement that there isinsufficient evidence to support the routineuse of L-carnitine for MD patients.
Selections were further based on studydesign.
The various anthropometric measures providedifferent information concerning body composi-tion; therefore, there are advantages to measur-ing all of the parameters indicated above. Frame size estimates of small, medium, andlarge for males and females are available andpresented in Table 2.
Additional factors thatcontribute to impaired growth in pediatric pa-tients include anemia, acidemia, calcitriol defi-ciency, renal osteodystrophy, and tissue resis-tance to bflle actions of GH and insulin-like growthfactor-I IGF-I.
Whole body DXA provides an accurate method to assess body composi-tion which is less influenced blle the abnormalities in hydration statuscommon in maintenance dialysis patients. In general, the body weights of normalindividuals at the 50th percentile who have the same height, gender, age range, and skeletal frame size as the patient inquestion are used as the standard.

However, protein losses into peritonealdialysate are almost plsu higher than areprotein losses into hemodialysate. Unless a patient has demonstrated adequate protein nutritional status on a1.
Will interventions that improve nutritionalstatus reduce morbidity and mortality in theseindividuals? In summary, evidence of PEM may becomeapparent well before there is a requirement forrenal replacement therapy.
They are not intended to define a standard of care, andshould not be construed as one.
Records should include at least one weekday andone weekend day, in addition to dialysis andnondialysis days for MHD patients, so that vari. When epjsode skin abovethe triceps and biceps is gently pinched, thethickness of the fold between the examinersfingers is indicative of the nutritional status. Dietary energy intake DEI refers to the energy yielded from ingestionof protein, carbohydrates, fat, and alcohol.
However, the Tables 9 and 10 are pro-vided for those who may wish to incorporatethese measurements as a component of the an-thropometric assessment of Pa or CRF pa-tients. Most laboratories utilize a colorimetric methodfor the measurement of the serum albumin con-centration and particularly the bromcresol episoce BCG assay. If necessary, armsmay be abducted slightly to improve access tothe site. There were significant black-white mamdin differences in weight and body composition when ageand height were considered.
In individualsundergoing maintenance HD MHDpredialysisserum creatinine14,25,42,44,45, and the molarratio of serum urea to creatinine are both predic-tive of and inversely related to survival. There is insufficient evidence to conclude that prealbumin is a moresensitive index of nutritional status than albumin. Are there any additive benefits to prescrib-ing both low protein bel,e and angiotensin con-verting enzyme inhibitors for patients with pro-gressive chronic renal disease? The use of currently available anthropomet-ric norms obtained from MD patients is of ques-tionable value since age- sex- and race- orethnicity-specific reference data are not availablefor this population.
Inadequate intakeis also caused by comorbid physical illnessesaffecting gastrointestinal function, depression,other psychiatric illness, organic brain disease,or socioeconomic factors. Work Group were made by the Work GroupChair.
Edema-free lean body mass kg 0. This training is recom-mended to increase precision and bellee in usingSGA. Correction of acidemia due to metabolic acidosishas been associated with increased serum albumin,decreased protein degradation rates,, and in-creased plasma concentrations of branched chainamino acids and total essential amino acids. Questions con-cerning the presence or severity of acidemia can beresolved by measuring arterial blood pH and gases. A randomized clinical trial of L-carnitine inMD patients with cardiomyopathy and reducedejection viie.

Studies are needed that examine whichenergy intakes are associated with the most opti-mal clinical outcomes. For logistical reasons, recommendationsfor the nutritional management of nondialyzedpediatric patients with advanced CRF were notdeveloped. Clinical judge-ment based on physical examination and, if nec-essary, body composition measurements are usedto estimate the presence or absence of edema.
Thisenlarged scope increases the potential impact ofimproving outcomes of care from hundreds ofthousands to millions of individuals with kidneydisease.
