Title: Nutrition Care in Chronic Kidney Disease

Nutrition Care in Chronic Kidney Disease An
  • Terry Banerjea, MS, RD, LDN
  • Barbara Edgar, RD, LDN

  • Understand goals of MNT for patients with CKD
  • Recognize renal related labs and their goal
  • Become familiar with dialysis medications and
    their functions

Medical Nutrition Therapy
  • Protein
  • Calories
  • Potassium
  • Phosphorus
  • Calcium
  • Sodium
  • Fluid
  • Vitamins
  • Minerals

  • The backbone of the diet
  • Essential for growth, muscle building, boosting
    the immune system, preventing infection, anemia
  • Important for wound healing
  • Measured as ALBUMIN in the blood
  • Albumin goal is gt4.0 to live longer and healthier

Protein/Calorie Malnutrition
  • 40 of hemodialysis patients are thought to have
    protein/calorie malnutrition.
  • Dialysis population has a two-fold increase in
    mortality risk for those with albumin lt3.8 g/dl
    vs. those with albumin gt 3.8 g/dl

Some Potential Reasons for Low Albumin
  • Loss of metabolic function in the failing kidney
    leads to build up of waste products leading to
  • Anorexia
  • Decrease in nutrient intake
  • Changes in hormones and metabolism
  • Insulin resistance
  • Increased hepatic glucagon sensitivity
  • Excessive parathyroid hormone secretion
  • Change in the rate of protein/amino acid turnover
  • Acidosis loss of protein and muscle mass
  • Increased cytokine activation (pro-inflammatory

Some Potential Reasons for Low Albumin
  • Use of multiple medications
  • Multiple co-morbidities
  • Loss of amino acids in dialysate
  • Reduced ability to synthesize albumin in the
    elderly leads to slight albumin decrease
  • Liver failure decreases albumin synthesis
  • Fluid overload leads to dilution of the serum
    (would falsely lower albumin and BUN)

Calories/ Protein in CKD
  • Appetite and intake may be poor due to
  • Aging
  • Frequent illness, hospitalizations
  • Institutional food
  • GI problems
  • Gastroparesis and diabetes
  • Constipation due to CaCO3, iron, narcotics, other
    medications, low fluid, low fiber, limited
  • Diarrhea due to C. difficile with antibiotic

Calories/Protein in CKD
  • Appetite is made worse by CKD and dialysis due
  • Anorexia caused by uremia
  • Nausea, vomiting, diarrhea
  • Dysgeusia due to uremia, zinc deficiency
  • Peritoneal Dialysis patients feeling of fullness
    from dialysate or sugar content of dialysate
  • Hemodialysis Interferes with regular meal pattern

Evaluating Protein Intake
  • Check Urea Reduction Rate (URR) or KT/V - URR
    should be gt70 and KT/V should be gt1.2
  • These measure dialysis adequacy and low values
    may adversely affect intake
  • Check nPCR
  • Normalized protein catabolic rate is determined
    from urea generation. It is an indicator of
    available protein. If patient is stable the nPCR
    indicates dietary protein as g/kg/EDW. nPCR will
    be low if protein intake is low or patient is

Evaluating Protein Intake
  • Check BUN 40-100 mg/dl
  • Urea derived from protein will decline if intake
    is poor or patient is anabolic
  • Check albumin (BCG) gt4.0
  • Albumin will decline if patient has trauma,
    infection, intake is poor, or if dialysis is

High Quality vs. Low Quality Protein
  • Dialysis patients should get 50 of their diet
  • LOW BIOLOGICAL VALUE protein generally come from
  • Vegetarians can still maintain acceptable albumin
    levels by combining plants sources with the use
    of supplements

How Much Protein Does a Person on Dialysis Need?
  • Hemodialysis patients need 1.2 or more grams/kg
  • Peritoneal patients need 1.3 or more grams/kg
  • Greater protein losses in dialysate
  • Appetite loss due to fullness experienced while
    the dialysate fluid in peritoneum
  • Effect of glucose when using higher concentration
  • These recommendations are based on K/DOQI

Inadequate Protein Intake
  • Muscle Wasting
  • Lack of Energy
  • Weight Loss
  • Poor Wound Healing
  • Albumin lt/3.5 considered protein malnutrition
    (Goal gt/4.0)
  • Low albumin can make it hard to dialyze fluid off
    of a patient

Evaluating Calorie Intake
  • Check EDW (Estimated Dry Weight)
  • Check IDWG (Interdialytic Weight Gain)
  • Check labs
  • Poor intake indicated by
  • Low BUN
  • Low Albumin
  • Low K
  • Low PO4

How Many Calories Does a Person on Dialysis Need?
  • Hemodialysis patients need 30-35 kcal/kg gt60
    years old, 35 kcal lt 60 years old
  • Obese dialysis patients 25 kcal/kg regardless of
  • Peritoneal dialysis patients have the same
    calorie requirements however the calories from
    the dialysate need to be included

Suggestions for Improving Intake
  • Encourage patient to not miss meals even when
    they are not hungry
  • Small, frequent meals
  • If a patient is eating poorly and K and PO4 are
    low- liberalize diet
  • If dysgeusia is present- eggs or cottage cheese
    may be better tolerated than meat, meat at room
  • Consider zinc supplement
  • Send lunch with patient to hemodialysis treatment
    if clinic allows or send supplement

Suggestions for Improving Intake
  • Protein recommendations are not a restriction
  • Do not sacrifice protein intake in order to lower
    PO4 intake
  • Help patient with fluid/sodium restriction
  • Avoid large fluid weight gains
  • Encourage physical activity to maintain muscle

Suggestions for Improving Intake
  • Protein may need to increase portion size if
    standards are used
  • Serve HBVP at 2 meals/day minimum
  • Serve at least 2 ounces HBVP
  • Serve 4-6 ounces HBVP at large meal
  • Include a HBVP with snack
  • Consider supplements

Snacks for Dialysis
  • Many dialysis patients miss 3 meals per week due
    to dialysis schedule so it is important to
    replace this meal with a protein rich snack
  • If patients do not wish to eat a sandwich or if
    it is not allowed, send a supplement as a meal
  • Snack Ideas
  • Egg salad, tuna salad, chicken salad, turkey or
    roast beef sandwich
  • Cheese stick and a piece of fruit
  • Greek yogurt
  • A peeled hard boiled egg
  • Binders should be sent with the bag meal

  • Absorbed in small intestine
  • 90 in cells
  • 8 in bones
  • lt1 in circulation
  • Excretion
  • 80-95 in urine
  • 5-20 in stools

  • Primary Roles of Potassium
  • Maintains fluid balance within cells
  • Conduction of nerve impulses
  • Muscle contraction

Potassium (K)
  • Normal serum potassium values3.5-5.1mEq/L
  • Goal range for dialysis patients3.5-6.0mEq/L
  • Serum level is dependent on urine output
  • K is usually WNL if producing gt1000cc/day
  • May be altered by diuretics and antihypertensive

Causes of High Potassium (Hyperkalemia)
  • Excessive potassium intake
  • Inadequate dialysis
  • Inadequate treatment time or missed treatments
  • Low blood flow rate, recirculation
  • Metabolic acidosis-causes K to shift from cell to

Causes of High Potassium (Hyperkalemia)
  • Dehydration-hyperosmolar state impairs cellular
    uptake of K
  • Insulin deficiency-cellular uptake of K requires
  • Blood transfusions-old packed cells will break
    down and release K
  • Hemolysis (incorrect handling of
    specimen)-release of K from RBC into serum

Causes of High Potassium (Hyperkalemia)
  • Catabolism due to tissue breakdown
  • Infection and ischemia (bowel)
  • Starvation
  • Trauma surgery
  • GI Bleed
  • Chewing tobacco
  • Use of illicit drugs
  • Some forms of pica
  • Constipation
  • Medications-ACE Inhibitors and ARBS (Angiotensin
    receptor blockers) which are commonly used for
    blood pressure control

Symptoms of Hyperkalemia
  • Muscle weakness
  • Numbness and tingling of extremities
  • Slow pulse rate
  • Heart attack

Diet Recommendations for Potassium
  • Hemodialysis 2-3 grams/day
  • Peritoneal Dialysis 3-4 grams/day however often
    times a restriction is not needed
  • A high K usually indicates treatments are not
    being done

High Potassium Fruits
  • Avocados
  • Bananas
  • Kiwi
  • Mango
  • Melons
  • Nectarines
  • Orange/juice
  • Papaya
  • Pomegranate
  • Prunes/juice
  • Raisins
  • Rhubarb

High Potassium Vegetables
  • Artichokes
  • Asparagus- fresh
  • Brussels sprouts
  • Dried beans and peas
  • Lima beans
  • Mushrooms
  • Potato-white/sweet
  • Pumpkin
  • Tomatoes and tomato products
  • Winter squash

Diet Recommendations
  • High potassium foods may be allowed in small
    amounts depending on frequency in meal plan
  • EXAMPLE ¼ cup of tomato sauce on noodles
  • Consult with renal dietitian

If K is high
  • Check URR (urea reduction rate) or KT/V
    (clearance of volume over time)
  • Check BS and HgbA1C for lack of insulin
  • Check Hgb and transferrin saturation for the
    possibility of a GI bleed
  • Check potassium if specimen was hemolyzed
  • Check medication list Captopril, Enalapril,
    Accupril, Lisinopril
  • Diet review

If K is high due to a non-dietary cause
  • Consult MD for changes
  • Blood pressure medications
  • Possible use of Kayexalate
  • Change dialysis bath (3K to a 2K)
  • Discontinue potassium supplement (KCl) if

  • Primary Roles of Phosphorus
  • Bone and Teeth Formation
  • Energy Metabolism
  • Acid-Base Balance

  • Normal serum phosphorus level2.6-4.5mg/dL
  • Goal range for dialysis patients3.0-5.5mg/dL
  • Three ways to control phosphorus
  • Diet restriction is nearly always necessary
  • Phosphate binders
  • Dialysis 800mg/treatment is removed at each
    hemodialysis treatment and 300-315mg/day for
    peritoneal dialysis

Symptoms of High Phosphorus (Hyperphosphatemia)
  • Itching
  • Blood shot eyes
  • Bone pain

Effects of High Phosphorus
  • Combines with calcium to form deposits in and
  • CVD, PVD
  • Calcification of soft tissue
  • Calciphylaxis
  • Causes parathyroid hormone to increase
  • Decalcification of bones
  • Bone pain, high risk of fractures

Relative Mortality Risk by Serum Phosphorus Levels
Dietary Recommendations for Phosphorus
  • 800-1000mg/day, adjust to meet protein needs
    (10-12mg/gram of protein) for hemodialysis and
    peritoneal dialysis

High Phosphorus Foods
  • Dairy products milk, cheese, ice cream, yogurt
  • Beans dry beans and legumes
  • Peanut butter and nuts
  • Chocolate products

  • Legumes
  • Limit foods that contain phosphorus additives
  • Processed and spreadable cheeses
  • Instant products-puddings and sauces
  • Cola, some flavored waters and fruit drinks
    (Hawaiian punch)
  • 90 of the phosphorus in additives are absorbed
    vs. 50 in natural foods

Phosphate Binders
  • Must be taken with meals and snacks to be
  • The active component of the phosphate binder
    combines with the digested phosphorus, forming a
    compound that is eliminated in the stool
  • Patients should also take a binder with the
    protein supplements

  • Calcium Carbonate Tums, Oscal, Caltrate

    dose for Renvela
  • Renagel lowers cholesterol due to binding with
    bile acids
  • Renagel lowers serum bicarbonate
  • Typical dose is 3 tablets per meal though some
    patients require more
  • Non-calcium based binder so is used for patients
    that have issues with hypercalcemia
  • Renvela comes in a powder form of 800mg or 2.4g
    that is mixed with 2 ounces of water for patients
    with swallowing issues
  • Renagel and Renvela may cause some n/v, diarrhea
    or gas

  • Tablet must be completely chewed, can not swallow
    whole pieces
  • Non-calcium based binder so is used for patients
    that have issues with hypercalcemia
  • May cause dark stools

  • Primary roles of calcium
  • Bone strength
  • Teeth formation
  • Catalyst in the conversion of prothrombin to
  • Involved in transmission of nerve impulses and
    relates to muscle contractions
  • Activates several enzymes such as lipase

  • Normal serum calcium level 8.4-10.2
  • Normal serum calcium level for dialysis patients

If Calcium is High
  • High Calcium levels can lead to calcification
  • Evaluate binder Change to a non-calcium based
    binder if on a calcium based binder
  • Evaluate Vitamin D analog hold or decrease dose
  • May need to start Sensipar which decreases PTH
    and calcium
  • Make sure calcium bath is 2.25
  • Counsel on avoiding calcium fortified foods

  • Receive calcium from diet, supplements, phosphate
    binders and dialysate
  • K/DOQI guidelines limit p.o. calcium to 2000mg
    from all sources
  • Limit calcium from phosphate binders and calcium
    supplements to 1500mg/day
  • Do not give calcium with iron or zinc supplements
  • Renal RD works with MD to change dialysis bath,
    phosphate binders as appropriate

  • Possible Problems for the Elderly
  • Decreased absorption due to achlorhydria
  • Calcium citrate may increase aluminum absorption
  • Calcium with a meal will decrease phosphorus
    (hence the calcium based phosphate binders)
  • Decrease response to Vitamin D
  • Immobility increases calcium loss

  • Drawbacks of Excess Calcium
  • Parathyroid over-suppression
  • Adynamic bone disease occurs with low parathyroid
    hormone (PTH)
  • Extraskeletal calcification may occur

Sodium and Fluids
  • Roles of Sodium
  • Principle electrolyte in extracellular fluid
    involved in the maintenance of normal osmotic
    pressure and water balance
  • Acid base balance
  • Osmotic equilibrium

Sodium and Fluids
  • Normal serum value is 136-145 mEq/L for the
    general population and dialysis patients
  • A high serum level indicates dehydration
  • Severe diarrhea
  • Vomiting
  • Diuretics
  • A low serum level indicates fluid overload
  • Low fluid intake
  • Edema

Sodium and Fluids
  • A high sodium intake results in
  • Thirst and increased fluid intake
  • Fluid drawn into interstitial space causing edema
  • High blood pressure
  • Shortness of breath when fluid is in lungs

Sodium and Fluids
  • Difficult Treatments
  • Sudden drop in blood pressure when large volumes
    are removed
  • Cramping when sodium in interstitial spaces is
    holding fluid which then cannot be removed
  • Nausea
  • A generally miserable treatment

Diet Recommendations for Sodium
  • Hemodialysis 2-3 grams per day
  • Peritoneal Dialysis 2-4 grams per day
  • Should be most strict when patient has CHF or is
    a cardio-renal patient and on weekends due to 3
    day interval
  • Avoid law sodium products with KCl added
  • Give salty foods as a special treat

Sodium and Fluids
  • Fluid Losses (non-urinary)
  • Perspiration from skin
  • Water vapor expired from lungs
  • Fecal losses or ostomy output
  • Fever

Sodium and Fluids
  • Diet Recommendations for Fluids
  • Hemodialysis 1000-1500 cc/day or
  • 1000 cc urine output/day
  • 1000 cc if anuric
  • Peritoneal dialysis to maintain balance
  • Patients should not push fluids but drink only to
    quench thirst
  • If a patient has residual renal function they can
    have more fluids.

Sodium and Fluids
  • Causes of High Interdialytic Weight Gains
  • Increase in intake of fluid due to excessive
  • High sodium intake
  • High serum glucose
  • High urea
  • Medications-antihypertensives, anti-inflammatories
    , decongestants, diuretics, sedatives,
    antianxiety, anti-depressant, anti-diarrhea,
  • Lack of saliva

Fluid Management in Dialysis
  • Assessing Fluid Retention
  • Hemodialysis check interdialytic weight gain
  • Goal during the week no more than 3 of EDW
  • Goal over the weekend no more than 5 of EDW
  • Peritoneal dialysis - check whether patient
  • Reaches target weight
  • May need a higher strength dialysate
  • Typically no fluid restriction required

Fluid Management in Dialysis
  • Any beverage or food that is fluid at room
    temperature is considered fluid (fruits and
    vegetables are not counted as fluid)
  • Fluid guidelines
  • Measure, monitor, mindful
  • Watch sodium intake
  • Take medications with meal beverages when
    possible or applesauce
  • Use only 4-8 ounce beverage containers
  • Avoid bedside water containers

Fluid Management in Dialysis
  • Suggestions for thirst control
  • Suck on lemon wedge or add lemon to water-citric
    acid increases saliva
  • Eat sour candy or mints
  • Chew gum
  • Rinse mouth with cold water or mouth wash
  • Eat frozen grapes, pineapple chunks, etc.
  • Brush teeth more often to feel refreshed
  • Use breath spray
  • Use Biotene mouthwash and other products

Vitamins and Minerals
  • Some nutrients are lost during dialysis
  • B Vitamins
  • Biotin- low levels are thought to result in
    restless leg syndrome
  • Folic Acid, B12, B6 low levels thought to be
    associated with homecysteinemia
  • Vitamin C
  • Zinc
  • Iron

Vitamins and Minerals
  • Fat soluble vitamins are stored in the body and
    not removed during dialysis so supplementation is
    not needed (Vitamin A,D,E,K)
  • Schedule renal multivitamin at bedtime to prevent
    removal at dialysis treatment

Vitamins and Minerals
  • Supplements are prescribed
  • Renavite, Renaplex, Nephrovite, Nephrocaps, Renal
    Caps, Prorenal, Triphocaps, Diatx, Dialyvite
  • Oral iron is used mainly for peritoneal patients
  • IV iron may be provided in-center (Venofer,

Vitamins and Minerals
  • Other vitamins and minerals accumulate and may be
  • Vitamin A
  • Vitamin D
  • Potassium
  • Calcium
  • Phosphorus
  • Iron
  • Therefore OTC vitamins are not recommended

Vitamins and Minerals
  • Vitamin D
  • 1,25 dihydroxy Vitamin D- calcitriol
  • 25, hydroxy Vitamin D - calcidol
  • Vitamin D2 ergocalciferol
  • Vitamin D3 cholecalciferol
  • Normal value is 30-100ng/ml
  • Vitamin D analogs
  • Hectorol
  • Zemplar
  • Calcitriol
  • Available IV for hemodialysis patients and oral
    for peritoneal patients used to manage
    parathyroid hormone (PTH) levels

Parathyroid Hormone (PTH)
  • Maintains calcium and phosphorus balance in the
  • Kidneys turn the active form of Vitamin D (from
    the sun and food/supplements) to the active form
  • When the kidneys do not work, PTH increases and
    active Vitamin D in the form of the Vitamin D
    analog is given to suppress PTH
  • Normal serum PTH 14-72pg/ml
  • Goal range for dialysis patients 150-600pg/ml

Parathyroid Hormone (PTH)
  • Parathyroid gland becomes less sensitive to
    calcium and Vitamin D
  • A high PTH can lead to
  • Increase risk for extraskeletal calcification
  • High turnover bone disease (osteitis fibrosa
  • Good bone is replaced with poorly formed bone and
    fibrous tissue
  • Also increases phosphorus

Parathyroid Hormone (PTH)
  • Treatment of Hyperparathyroidism
  • Vitamin D analogs
  • Zemplar (paricalcitol)
  • Hectorol (doxercalciferol)
  • Calcijex and Rocaltrol (calcitriol)
  • Parathyroidectomy If PTH gt 1000
  • Calciminetics - Sensipar

  • PTH, calcium and phosphorus decrease
  • Doses are 30mg, 60mg, 90mg, 120mg and 180mg
  • PTH is monitored monthly until goal range is met
  • Dose of sensipar is increased until goal range is
  • Patients continue to receive Vitamin D analogs
  • Hypocalcemia can be a problem so calcium level is
    monitored closely

  • Calcium level drops
  • Patients will need calcium supplements, usually
    1-2 gm tid between meals
  • May need to change from a non-calcium based
    binder (Renvela, Renagel, Fosrenol, Velphoro) to
    a calcium-based binder (calcium carbonate or
    calcium acetate)
  • Phosphorus usually drops as well but patients
    still need phosphate binder
  • May supplement with calcitriol as a calcium
  • May change calcium bath from a 2.25 to a 3.0

  • PTH lt100
  • Leads to adynamic bone disease
  • Low rates of bone formation
  • Decreased numbers of osteoblasts and osteoclasts
  • Osteomalacia (related to aluminum or Vitamin D

  • Constipation is a common problem in the dialysis
    population due to
  • Fluid restriction
  • Lack of exercise
  • Medications
  • Calcium carbonate, oral iron supplements,

  • Low Fiber Intake
  • Restriction of fruits and vegetables due to the
    high potassium content of them
  • Self restriction of fruit and vegetables due to
    GI problems or food preferences
  • Poor general intake

  • Prevention/Treatment of Constipation
  • Encourage fruit and vegetable intake within
    limits of potassium restriction
  • Encourage exercise
  • Fiber supplements and stool softners can be used
  • Unifiber, Metamucil, Miralax, Colace, Senokot
  • Laxatives
  • Dolcolax, Lactulose, Sorbitol, Docusate Sodium
  • Enemas
  • Mineral Oils, Soap suds
  • Fleets should not be used

Factors to Consider in Choosing a Nutritional
  • Current Oral Intake
  • Recent Lab Values
  • Co-morbidities
  • Body weight
  • Fluid status
  • Recent changes in health status
  • Cognitive state
  • Patient preferences

Important Content of the Nutritional Supplement

  • lt200 mg phosphorus

Renal Supplements
  • Nepro
  • Novasource Renal
  • Re/Gen
  • Suplena used for pre-dialysis patients only
    that need to be on a low protein diet

Non-Renal Supplements
  • Can be useful when a patients potassium and
    phosphorus are well controlled
  • Some patients may also find these choices more

Non-Renal Supplements
  • Boost
  • Ensure
  • Liquacel
  • Pro-Stat
  • Procel Powder
  • Protein Bars
  • Body Quest Ice Cream
  • Enlive
  • Resource

  • Providing supplements in small amounts throughout
    the day i.e. a med pass program, can be useful
    for patients with limited appetite and to
    decrease fluid intake

Vegetarian Diet for Dialysis Patients
  • Protein
  • Vegetable proteins include foods such as legumes,
    beans, nuts, seeds, soy products such as soy
    milk, tofu and meat analogs
  • Tofu is a good protein choice because it is low
    in sodium, potassium and phosphorus and is very
  • Select regular or silken tofu as they contain
    less potassium than extra firm or firm tofu
  • Legumes are a good source of protein and soluable
    fiber but can be a major contributor to a high
    potassium level in the blood
  • The following beans are lower in potassium
  • Lupin, chickpeas, black beans, black eye peas,
    red kidney, pinto as well as hummus which is
    made from chickpeas
  • Meat analogs can be used in moderation if
    balanced with other lower sodiun foods
  • Consider using protein powder or other
    supplements depending on the type of vegetarian

Vegetarian Diet for Dialysis Patients
  • Meat analogs
  • Many provide 10-24 grams of protein per serving
  • They are made from soy protein with flavor and
    color added so they taste and feel like real meat
  • Contain a lot of sodium so check labels
  • Brands Morningstar Farms, Loma Linda, Green

Vegetarian Diet for Dialysis Patients
  • Phosphorus
  • Some of the foods that contain high levels of
    phosphorus include beans, nuts and whole grains
  • Phosphate found in vegetable protein is not
    absorbed as well as the phosphorus found in the
    animal protein
  • Phosphate binders are necessary to manage
    phsophorus levels

Vegetarian Diet for Dialysis Patients
  • Potassium
  • Always select the lower potassium fruits and
  • Grains also contain potassium -the lower
    potassium grains would be rice and barley
  • Avoid quinoa, miso and naho
  • Avoid high potassium legumes such as lentils,
    soybeans, adzuki, navy and white beans

Vegetarian Diet for Dialysis Patients
  • Calories
  • When following a renal diet it is often a

Nursing Home Considerations
  • Monthly communication between dietary and nursing
    staff at the nursing home and the dialysis
    dietitian is essential
  • Each renal patient is different and may have
    different dietary needs, a standard diet may not
    be appropriate
  • Avoid high phosphorus and potassium snacks save
    them for special occasions when the nursing home
    is a special event

In Conclusion
  • Our goals for our patients both in the dialysis
    clinic and in the ECF is to
  • Ensure their best possible health
  • Maintain blood chemistries WNL
