Yajie Zhang KNH 411 November 18, 2012 Case 27 Renal Transplant i. Understanding the Disease and Pathophysiology 1. Describe the physiological functions of the kidneys. The primary functions of the kidney include maintenance of homeostasis through control of fluid, pH, and electrolyte balance and blood pressure; excretion of metabolic end-products and foreign substances; and the production of enzymes and hormones. (522) 2. What diseases/conditions can lead to chronic kidney disease (CKD)? Chronic kidney disease (CKD) is a syndrome of progressive and irreversible loss of the excretory, endocrine, and metabolic functions of the kidney secondary to kidney damage. CKD progresses slowly over time, and there may be intervals during which kidney functions remain stable. Having a glomerular filtration rate (GFR) of less than 60 mL/min/1.73m2 for three months or longer and/or albuminuria of more than 30 mg or urinary albumin per gram of urinary creatinine has been defined as CKD. Diabetes, hypertension, and glomerulonephritis are the leading causes of kidney failure. Ethnicity, family history, hereditary factors such as polycystic kidney disease (PKD), a direct and forceful blow to the kidneys, and prolonged consumption of over-the-counter painkillers that combine aspirin, acetaminophen, and other medicines such as ibuprofen are also risk factors associated with CKD. (526) 3. What was the likely cause of Mrs. Joaquin’s CKD? Mrs. Joaquin’s blood pressure is 130/85 which is in the range of prehypertension. She has type 2 diabetes. She is a Native American that Native American is nearly two times as likely to develop kidney failure. The factors listed above were the likely causes of Mrs. Joaquin’s CKD. 4. Mrs. Joaquin’s transplant evaluation took place 2 years ago and included each of the following. What were each of these procedures used to evaluate? Procedure Abdominal and renal ultrasound EKG and echocardiogram Chest X-ray Meeting with transplant nurse, social worker, surgeon, and financial counselor Blood typing and tissue typing Dental exam Viral testing on blood Mammogram and PAP test Used to Evaluate A radiology study that evaluates the liver, gallbladder and native kidneys for abnormalities. EKG - shows heart function and reveals any past damage. Echocardiogram - to check the heart structures & valves. A picture of your lungs and lower respiratory tract, which will identify any abnormalities. -To help the doctor coordinate his care -To make sure learn about the emotional aspects of a kidney transplant -To help choose the best foods to eat. Check to see if it is type A, B, AB or O blood type and what tissue typing it is. To detect any infections, cavities, or gum disease, which may be a source of infection after transplant. Blood for viruses, such as Epst Epstein Bar ein Barr Virus r Virus (EBEBV) V), Cytomegalovir ytomegalovirus us (CMV) and BK Gynecologic exam, pap smear (age≥18 or sexually active), and mammograms (x-ray of breast) for cancer screening (age>40 or family history of breast cancer) are needed. (Kidney transplantation) 5. Describe why the immunological characteristics of the donated organ must match with the recipient’s medical and immunological characteristics. Since the presence of a MHC antigen on the transplanted organ or tissue that is different from the MHC antigens on the recipient’s tissues signals the presence of the transplanted tissue and initiated an immune response, MHC antigens for MHC play an important role in transplant rejection. The immune system attacks the transplanted cells presenting MHC antigens that are different from those found on the recipient’s tissues. Therefore, the match is necessary to make the immune system less offensive to the new organ. (529) 6. Explain the role of the major histocompatibility complex (MHC). The role of the major histocompatibility complex (MHC) in determining acceptability for a transplanted organ is important. The antigens for MHC (often referred to as human leukocyte antigens [HLA]) provide the basis for the MHC haplotype (a combination of closely linked genes on a chromosome inherited as a unit from one parent). The presence of a MHC antigen on the transplanted organ or tissue that is different from the MHC antigens on the recipient’s tissues signals the presence of the transplanted tissue and initiated an immune response; MHC antigens for MHC play an important role in transplant rejection. (529) ii. Understanding the Nutriton Therapy 7. What are the differences between nutrition therapy during the acute phase (up to 8 weeks following transplant) and during the chronic phase (starting ninth week following transplantation) post-transplantation? Explain the rationale for each. Nutrient Protein Acute Phase 1.3-1.5g/kg; based on standard or adjusted body weight Energy 30%-35% kacl/kg; may increase with postoperative complications Carbohydrates 50%-60% of total kcal; limit simple CHO if intolerance is apparent Fats 25%-35% of total kcal Chronic Phase 1.0g/kg; limit with chronic graft dysfunction Rationale -postoperative stress and the excessive doses of corticosteroids -manage dyslipidemia, diabetes, obesity, and cardiovascular disease Maintain -postoperative stress desirable weight and the excessive doses of corticosteroids -manage dyslipidemia, diabetes, obesity, and cardiovascular disease 50%-60% of total -impaired glucose kcal; emphasis on tolerance and the complex CHO potential for and 20-30g development of dietary fiber posttransplant (5-10 g per day diabetes mellitus soluble fiber) 25%-35% of total -cardiovascular kcal with disease is the Cholesterol --- Potassium 2000-4000 mg if hyperkalemia exists Sodium Calcium Phosphorus Vitamins/minerals Fluids iii. saturated fat < 7% of total kcal; up to 10% of kcal from PUFA, and up to 20% of kcal from MUFA <200 mg per day; consider plant stanols/sterols, 2 g per day leading cause of mortality in kidney transplant patients -cardiovascular disease is the leading cause of mortality in kidney transplant patients -help to regulate hyperkalemia No restriction unless hyperkalemia exists 2000-4000 mg 2000-4000 mg -help to regulate may be necessary with hypertension hypertension 1200-1500 mg 1200-1500 mg -to prevent osteoporosis and altered vitamin D metabolism 1200-1500 mg 1200-1500 mg -to prevent (supplements (supplements hyperparathyroidism may be needed) may be needed) issue Dietary reference Dietary reference -Corticosteroids intake intake; may need leaded reduced additional intestinal absorption vitamin D of calcium and hypercalciuria No restriction No restriction NA unless graft not unless graft not functioning functioning Nutrition Assessment A. Evaluation of Weight/Body Composition 8. Calculate Mrs. Joaquin’s BMI. HT = 5 feet * 12 inch / 39.37 inch / m = 1.52 m WT = 165 lb / 2.2 lb/kg = 75 kg BMI = WT/HT2 = 75 kg/1.522 m = 32.46 kg/m2 (Obese State One) 9. How would you interpret Mrs. Joaquin’s BMI? Explain your rationale. Based on Mrs. Joaquin’s BMI, she is considered to fall in the obese state one category. It might be related to her type 2 DM. B. Calculation of Nutrient Requirements 10. What are the recommendations for estimating energy requirements for (post) renal transplantation? Calculate Mrs. Joaquin’s energy needs accordingly. 30 – 35 kcal/kg Range = 30*75-35*75 = 2250 kcal – 2625 kcal 11. What will Mrs. Joaquin’s protein requirements be after the transplant? 1.3 – 1.5 g/kg Range = 1.3 * 75 – 1.5 * 75 = 97.5 g – 112.5 g 12. Compare her energy and protein needs prior to and post-transplant. Explain how and why they are different. Compared to her energy and protein needs prior-transplant, post-transplant has the higher requirements of both protein and energy amount. This is basically due to the postoperative stress and the excessive doses of corticosteroids. C. Intake Domain 13. Explain the importance of food safety education for transplant patients. Organ transplant patients are included on the list of immune compromised persons at highest risk of foodborne illness. Organ transplant patients are at high risk for infection during medical treatment and at continuing risk for the rest of their lives due to drug treatment used to prevent rejection of the transplanted organ. Therefore, food safety education is extremely important for transplant patients to prevent foodborne illness. D. Clinical Domain 14. On POD #2, Mrs. Joaquin was doing well and transferred to the medical floor. Her Results showed good perfusion and function of the kidney. Her intake and output were good. During the remainder of her hospitalization, Mrs. Joaquin received detailed instructions about postoperative care and medications. The instructions were: Keep incision clean and dry Staples will be removed in 3 weeks Avoid lifting over 5 pounds Can resume driving and sexual activity in 2-4 weeks or when pain free Follow prescribed diet Explain why the following medications were prescribed, and indicate any nutrition implications. Medication Indications/Mechanism Nutritional Implications No potassium supplements or salt substitutes. Avoid grapefruit and red wine. Anorexia is a concern. Neoral Indicated for the prevention of organ rejection in kidney, liver, and heart transplants. Imuran Immunosuppressant works Anorexia, steatorrhea. as an adjunct for the Take with food to prevention of rejection in prevent upset stomach. renal transplantation. Prednisone Corticosteroid that prevents inflammation. Caution with DM patients, highly protein bound; may need increased K, PO4, CA, and vitamins A, C, and D, increased protein, decreased dietary sodium; avoid alcohol Magnesium oxide Can be used as a magnesium supplement, but also commonly as an antacid. Diarrhea is common side effect. Bactrim Treats bacterial infections (due to suppressed immune system) Neutral-phos Used as a phosphorus supplement Nausea and vomiting are common side effects. Should be taken on an empty stomach. Limit alcohol intake Must closely monitor potassium levels while taking medication Persantine Indicated as an adjunct to coumarin anticoagulants in the prevention of postoperative clot Vomiting, diarrhea. Dizziness is common so alcohol should be limited/ avoided. formations Caffeine may interfere with the drug’s effects. Omeprazole Prevents and/or treats stomach ulcers caused by other medications Glucophage Antihyperglycemic agent, biguanide; increases effect of insulin, lowers GI glucose absorption, decreases hepatic glucose production Nausea. Vomiting, diarrhea. May deplete or interfere with the absorption of calcium. Folic acid, and vitamin C. supplementation may be necessary. Anorexia, weight stable or declines, decreases folate and vit B12 absorptaion; caution with severe decrease renal function (Drugs and supplements) 15. Explain the role of immunosuppression in organ transplantation. After transplantation, patients are maintained on a variety of immunosuppressive regiments to prevent rejection of the donated kidney. (530) 16. How long will Mrs. Joaquin require immunosuppression? Immunosuppressive treatment of Mrs. Joaquin will begin with the induction phase, perioperatively and immediately after transplantation. Maintenance therapy then continues for the life of the allograft. Induction and maintenance strategies use different medicines at specific doses or at doses adjusted to achieve target therapeutic levels to give her the best hope for long-term graft survival. Maintenance immunosuppression is the key to prevention of acute and chronic rejections throughout the life of the graft. (Pellegrrino) 17. How will taking prednisone for her transplant affect her glycemic control? Prednisone might negatively affect her glycemic control by increasing appetite and causing hyperglycemia. (548) 18. Mrs. Joaquin is also instructed to watch for signs of rejection. Explain what is meant by rejection and list at least three signs of transplant rejection. Acute rejection is where the WBC put up a defense against the organ because it doesn’t recognize it and the organ can don’t function to its full ability. However, there are medications that can reverse the rejection and the organ can regain full function. Acute rejections are not likely after the first year of transplantation. Chronic rejection is where the body’s antigens attack the organ slowly and continuously either leaving the organ impaired or unable to function altogether. This would require immediate hospitalization and the need for another transplant quickly. Signs of transplant rejection: the organ’s function may start to decrease; general discomfort, uneasiness, or ill feeling; pain or swelling in the area of the organ (rare); fever (rare); flu-like symptoms, including chills, body aches, nausea, cough, and shortness of breath. (549) 19. What will happen if Mrs. Joaquin does reject her transplanted kidney? She might experience decreased kidney function; general discomfort, uneasiness, or ill feeling and pain or swelling in the area of the organ (rare); fever (rare); flu-like symptoms, including chills, body aches, nausea, cough, and shortness of breath. If her new kidney fails, she can resume dialysis or consider a second transplant. She may also choose to discontinue treatment. (Yasumuan) E. Behavioral-Environmental Domain 20. Mrs. Joaquin tells you that she’s heard transplant patients gain weight after surgery, and she wants to know if this will happen to her. How do you answer her question? I would tell Mrs. Joaquin, many transplant patients develop nutrition-related problems in the months and years following transplant. The most common are excessive weight gain (as fat) and high blood cholesterol that are usually caused by steroids and other medications. The best management for you includes weight control by following a "heart healthy" diet and exercising. Here are some guidelines that will help decrease the amount of total fat and cholesterol in your diet. They will help reduce your risk for heart disease and excessive weight gain. A good way to manage this problem would be reading food labels carefully to avoid foods that are high in saturated fats and cholesterol. Some of these foods include lard, butter, shortening, ice cream, sausage, and bacon. Coconut and palm oils are saturated fats found in many convenience baked goods, whipped toppings, coffee creamers and fried foods. In addition, you could follow these guidelines: Choose low-fat milk and other low-fat or nonfat dairy products. Limit egg yolks to 3 or 4 per week. Many recipes can be made with egg whites or an egg substitute without compromising taste. iv. Choose the leanest varieties of beef and pork; avoid fried meats. Poultry (without skin), beans, and fish are excellent main course selections when cooked without fat. To increase the fiber in your diet, eat more fresh fruits, raw vegetables, and whole grains. A high-fiber diet may also help lower your cholesterol. Reduce your total calories by eating smaller portions and avoiding second helpings. Choose low-calorie snacks, such as fresh fruit, low-fat cookies or crackers and unsalted pretzels. Remember, just because a food is "low-fat" does not mean that you won't gain weight if you eat too much. Continue to limit salt intake and high-sodium foods to control blood pressure. Continue to limit simple sugars, especially if you are overweight. Do not eat sushi or any other raw or undercooked meat or fish. Nutrition Diagnosis 21. Prioritize the nutrition diagnoses by listing them in the order in which you would expect interventions to be developed. Overweight/obesity NC-3.3 Altered Nutrition related laboratory values BUN, Creatinine, Phosphorus NC-2.2 Inadequate mineral intake of Phosphorus (6) NI-5.10.1 Inadequate protein-energy intake NI-5.3 Excessive mineral intake of Potassium (5) NI-5.10.2 Undesirable food choices NB-1.7 22. Select two high-priority nutrition problems and complete the PES statement for each. Overweight/obesity related to increase calorie needs and medication as evidence by high LDL, chols and BMI. Altered Nutrition related laboratory values BUN, Creatinine, Phosphorus related to kidney dysfunction as evidence of CKD and lab values. v. Nutrition Intervention 23. Using your PES statement, establish an ideal goal (based on the signs and symptoms) and appropriate intervention (based on the etiology). Goals: Average daily caloric intake will be no more than the range of estimated needs about 2250-2625 kcal/day. Lab values will be controlled as BUN levels between 8-18 mg/dL, Creatinine levels between 0.6-1.2 mg/dL, and phosphorus between 30-120 mg/dL. Interventions: Though the client is overweight, she still needs to follow the EER to get enough energy intake which might affect her post surgery recovery. Instruct client on 2250-2625 kcal diet and educate client with basic post-transplant knowledge and better food choices knowledge Educate client how to achieve altered nutrition related laboratory values BUN, Creatinine, and Phosphorus control and how to manage those values by increasing the kidney functions. 24. Using Mrs. Joaquin’s typical intake and the prescribed diet, write a sample menu for her post-transplant nutritional needs. Meal Breakfast Snack Lunch Snack Sample Menu Corn flakes, 1 c Milk (1%), 1/2 c Bread (white), 1 slice Margarine, whipped, 2t Scrambled egg, 1 lg Tangerine, 1 med Water, 2 fo Pita bread, white, 2med Green bell pepper, ¼c Margarine, whipped, unsalted 1 T Water, 2 fo Sandwich: Bread (white) 2 slices Deli turkey, low-sodium, fat-free, 3oz Mustard 1 tsp Tortilla chips, unsalted, 1 oz Plum, med Root beer, 8 fo Dried cranberries, 1.5 oz Dinner Snack Goals Energy Protein Sodium Potassium Phosphorus Water Lean beef, 3 oz Rice, 1 c Green beans, 1 c Pita bread, 1 med Margarine, 1 T Saltine crackers, low sodium, 6 Peanut butter, unsalted, 1T Grapes, 1 c 2,250 kcal 97 g 2,013 mg 1,952 mg 945 mg 1,327 mL (Sclafani) 25. Write an initial medical record note for your consultation with Mrs. Joaquin. A (Assessment) Mrs. Joaquin is a 26-yo obese Native American female (60”, 165#, BMI 32.46kg/m2). She was diagnosed with T2DM at 13 years of age and with stage 5 CKD 2 yrs ago when she was placed on hemodialysis. Her kidney function has progressively declined and she was admitted to the hospital for preparation for kidney transplantation and nutrition consult. She has elevated serum phosphorus, potassium, creatinine, BUN, glucose, TG, HbA1c and cholesterol, which places her at stage 5 CKD. She reported a good appetite and has following the diet prescribed when she began hemodialysis. D (Diagnosis) 1. Overweight/obesity related to increase calorie needs and medication as evidence by high LDL, chols and BMI. 2. Altered Nutrition related laboratory values BUN, Creatinine, Phosphorus related to kidney dysfunction as evidence of CKD and lab values. I (Intervention) Goals: Average daily caloric intake will be no more than the range of estimated needs about 2250-2625 kcal/day. Lab values will be controlled as BUN levels between 8-18 mg/dL, Creatinine levels between 0.6-1.2 mg/dL, and phosphorus between 30-120 mg/dL. Interventions: Though the client is overweight, she still needs to follow the EER to get enough energy intake which might affect her post surgery recovery. Instruct client on 2250-2625 kcal diet and educate client with basic post-transplant knowledge and better food choices knowledge Educate client how to achieve altered nutrition related laboratory values BUN, Creatinine, and Phosphorus control and how to manage those values by increasing the kidney functions.
