  1. Nutrition Therapy and Dialysis Melinda S. Leone, MS, RD St. Joseph's Regional Medical Center Division of Nephrology Paterson, NJ 07503 leonem@sjhmc.org

  2. Objectives • Participant will be able to describe the importance of nutrition intervention in patients with ESRD • Participant will be able to identify the components of a nutritional assessment • Participant will be able to identify the components of the renal diet and the role of the dietitian

  3. Does Nutrition Status Matter?YES! • Nutritional indicators can be directly linked to patient status and outcome • Protein-Energy Malnutrition (PEM)1 • BMI2 • Albumin3, 4 • Potassium • Phosphorus5 • Calcium

  4. Renal Osteodystrophy • Hyperphosphatemia • Vascular and non-vascular calcification5 • Hypocalcemia • Secondary Hyperparathyroidism • Bone Disease • Low bone mass and density • Osteitis fibrosa cystica

  5. Protein Energy Malnutrition6 PEM • Malnutrition • PEM: marasmus-kwashiorkor • muscle/fat wasting • weight loss • Marasmus: Inadequate nutrient intake • Kwashiorkor: Inadequate protein intake • Cachexia

  6. Uremic Syndrome Malaise Weakness Nausea and vomiting Muscle cramps Itching Metallic taste Neurologic impairment Hospitalizations Co-morbidities Diabetes Infections Amputations Cancer Inflammation Causes of Malnutrition

  7. Protein–energy wasting syndrome in kidney disease7

  8. Nutrition Assessment Anthropometric Data • Height • Weight status • Frame size • Arm anthropometrics • Appearance • Amputations

  9. Nutrition Assessment Weight Status Evaluation • Standard Body Weight (SBW) • Body Mass Index (BMI) • Ideal Body Weight (IBW) • Adjusted Body Weight • Usual Body Weight (UBW)

  10. Nutrition Assessment Weight Status Evaluation • Weight changes • Intentional vs. unintentional weight loss • Dry weight changes vs. fluid shifts • Clinically significant weight loss • 5% or > within 1 month • 7.5% or > within 3 months • 10% or > within 6 months • Attitude toward changes • Goals for weight changes

  11. Nutrition Assessment6Interdialytic Weight Gain (IDWG) • General recommendation +2 kg • >5% fluid gains • Excessive fluid intake • Weight gain • <2% fluid gain • Inadequate fluid and/or food intake • Weight Loss/Decreased body mass

  12. Appetite/Intake Food preferences Allergies/Intolerance Taste changes Acute or chronic GI concerns Swallowing/Chewing concerns Urine output Pica Religious/Cultural Restriction Supplement intake Homeopathic Treatments Nutrition Knowledge Nutrition Assessment Diet History

  13. Shopping and Cooking Abilities Facilities Medication Side Effects Compliance Physical limitations Psychosocial problems Emotional support Economic limitations Depression Adjustment to disease Treatment Compliance Nutrition Assessment Diet History

  14. Food Records 24 Hour Recall 3 Day Food Record 3 Day Calorie Count Food Frequency Questionnaire Diet Assessment Calories Protein Carbohydrates Fat/Cholesterol Sodium Potassium Phosphorus Fluid Vitamins Minerals Nutrition Assessment Diet History

  15. Monthly Albumin: 4.0g /dL or > Potassium: 3.5-5.3 mEq/L Phosphorus: 3.5-5.5 mg/dL Calcium: 8.4-10.2 mg/dl Glucose <200 mg/dL Non-fasting Product: < 55 URR: >65% Hgb: 10-12 g/dL Quarterly Hemoglobin A1C: < 7% PTH: 150-600 pg/mL Lipid Panel Chol < 200 mg/dL HDL > 40mg/dL LDL <100mg/dL Triglycerides <200 mg/dL Nutrition Assessment Laboratory Analysis6

  16. Nutrition Assessment: Subjective Global Assessment6 • Protein-energy nutritional status measurement • Valid and reliable8 • KDOQI recommended9 • Medical history and physical exam • Body composition focus on nutrient intake • Subjective rating: 7 point scale6 • Well-nourished • Mild to moderately malnourished • Severely malnourished

  17. Nutrient Needs KDOQI Guidelines9

  18. Nutrient Needs KDOQI Guidelines9 Vitamins and Minerals

  19. Nutrition Therapy Goals • Provide an attractive and palatable diet • Control edema and serum electrolytes • Prevent nutritional deficiencies • Prevent renal osteodystrophy • Prevent cardiovascular complications

  20. Dialysis Diet • Diet Order • 2000 calorie, 80 g protein, 2 g Na+, 2 g K+, 1 g PO4, 1500 ml fluid restriction • Meal Planning • Individualize diet for patient’s lifestyle • Assistance programs • Nursing Homes • National Renal Diet: American Dietetic Association10

  21. Dialysis Diet • Adequacy and Balance • Calories • Protein • Variety • Actual intakes of HD patients11 • 23 kcals/kg/day • Less than 1 g/kg/day

  22. Albumin • Controversial key nutrition status measure12 • Depressed values • PEM, fluid overload, chronic liver/pancreatic disease, steatorrhea, inflammatory GI disease, infection, catabolism r/t surgery, abnormalities in protein metabolism, acidosis6 • Elevated Values • Dehydration, high dietary protein intake6

  23. Dialysis Treatment HD: 10-12 g free amino acids lost13 Losses increase with glucose free dialysate PD: 5 to 15 g protein lost9, 14 Lost as albumin Albumin

  24. Protein • 1.2-1.3 g protein/kg SBW9 • Average patient: 80 g Protein • 50% HBV protein foods • HBV Proteins • Beef, poultry, fish, shell fish, fresh pork, turkey, eggs, cottage cheese, soy • 6 to 10 ounces daily • Protein Alternatives • protein bars, protein powders, supplement drinks

  25. Potassium • 2-3 g daily9 - adjust per serum levels • Dialysis bath concentrations • Stricter diet restrictions • Insulin deficiency, metabolic acidosis, beta blocker or aldosterone antagonists treatments, hypercatabolic state • Non-diet causes Hyperkalemia • Hemolysis, high glucose, insulin deficiency, inadequate dialysis, incorrect dialysate potassium concentration, starvation, catabolism, sickle cell anemia, Addison's disease, long-term constipation15

  26. Avoid Highest Foods Oranges/Juice Banana Potato Plantains Mango Melon Avocado Tomato Nuts Fruits & Vegetables Low: 20-150 mg Medium: 150-250 mg High: 250-550 mg Portion size is essential Avoid Salt Substitutes Dairy 1 cup 380-400 mg High phosphorus foods Potassium10

  27. Phosphorus • Dietary intake ~800 to 1000 mg/day <17 mg/kg SBW • HD removes ~500-1000 mg/treatment • PD removes ~400 mg/treatment • 50% dietary phosphorus removed by binders16 • Control = Binders + Diet + Adequate dialysis

  28. Phosphate Binders

  29. Phosphorus Balance Weekly Phosphorus Balance + 4200 (diet) – 2100 (Binders) – 2100( HD) = Balance

  30. High Phosphorus Foods Dairy products Beans & Nuts Processed meats Chocolate Pancakes, waffles, biscuits, cakes Sardines Whole wheat, bran cereals Lower Phosphorus Foods Fresh meat products Homemade baked goods Nondairy creamer Unenriched rice milk Cream cheese White flour products Rice cakes Phosphorus10

  31. Phosphorus Additives • Inorganic Phosphorus absorbed easily • Phosphorus binders ineffective with many additives • READ THE INGREDENTS LABEL!! • Phosphoric acid • Sodium hexametaphosphate • Calcium phosphate • Disodium phosphate • Trisodium triphosphate • Monosodium phosphate • Sodium tripolyphosphate • Tetrasodium pyrophosphate • Potassium tripolyphosphate

  32. Calcium • Use corrected calcium (adjusted calcium) for albumin <46 Calculation: [ (4-albumin) x 0.8] + Ca++] • Diet: Less than 2 g daily • Hypercalcemia • Ca++ based binders, supplements • Vitamin D analogs/treatment • Diet, fortified foods • Dialysate calcium levels • Hypocalcemia • Vitamin D, Calcijex • Supplement between meals

  33. Parathyroid Hormone (PTH) • Vitamin D is activated in the kidney to calcitriol, or vitamin D31 • Vitamin D3 levels fall with kidney failure Calcium absorption ↓ and phosphorus excretion ↓ PTH increases => bone disease • Vitamin D3 therapy helps prevent renal bone disease • Ca and Phosphorus precipitate and calcify soft tissue • Ca x Phos product goal range with treatment

  34. Fluid • HD • Urine Output + 1000 ml • Limit IDWG • 2-5% Estimated Dry weight • PD • Maintain fluid balance • Vary dextrose concentrations in dialysate • Restrict if fluid balance not obtained without frequent hypertonic exchanges

  35. Sodium1,6 • ≥ 1 L fluid output: 2-3 g Na and 2 L fluid • ≤ 1 L fluid output: 2 g Na and 1-1.5 L fluid • Anuria: 2 g Na and 1 L fluid • Individualize • IDWG, blood pressure, residual renal functions • Increased Restrictions if ↑ IDWG, CHF, edema, HTN • PD: liberalize restriction to 2-4 grams sodium • High sodium intake may increase thirst

  36. Lipids10 • Increased risk of lipid disorders • Recommended fat intake • Total Fat <30% of calories • Saturated fat <10% • Cholesterol <300 mg/day • Difficult restrictions to achieve • Omega 3 supplements for elevated triglycerides • Optimum fiber intake 20-25 g/day

  37. Micronutrients1,6 • Renal Multivitamin containing water soluble vitamins17 • Dialyzable – take after dialysis • Vitamin C in renal vitamin • Limit total vitamin C 60-100 mg ↑ Vitamin C → ↑ oxalate → calcification of soft tissues and kidney stones • Individualize: Fe++, Vitamin D, Ca++, Zinc

  38. Specific PD Concerns • Higher protein needs • Lose 5-15 grams of protein a day 9, 14 • Weight Gain1 • Include dialysate calories in total intake • May absorb as much as 1/3 (500-800 kcals)of daily energy needs • Limit sodium and fluid to minimize hypertonic exchanges • Hypertonic agents such as Icodextrin (Extraneal) • High Triglycerides6 • Modify intake of sugars/carbohydrates • Limit intake of fats, saturated fats

  39. Nutritional Supplements • Oral supplements: Nepro, Ensure, Boost • Powders: Beneprotein, ProSource, Eggpro • Modular Protein: Pro-Stat, Promod • Cookies: NutraBalance • Protein Bars • Meal replacements vs. snacks • Over the counter • Evaluate potassium, phosphorus

  40. Nutrition Support Enteral • Oral Supplements • Barriers: compliance, fluid , palatability, cost • Tube feeding • Renal Formulas • Nepro and Novasource Renal • Barriers: acceptance, intolerance, tube placement, fluid intake, reimbursements, assistance

  41. Nutrition Support Parenteral • IDPN • Barriers • Oral intake is maximized without improvement in status • Usually requires documented malabsorption diagnosis • Benefits • Supplemented during treatment • No additional tube/access needed • Dialysis clinics have individual rules and criteria • Specific qualifying criteria from insurance companies
