Family history includes father who died of stroke, and mother with type 2 diabetes currently on oral meds. He was referred for Medical Nutrition Therapy by his nephrologist who has seen him twice so far. The MNT service was approved for coverage based on Medicare guidelines. Patient is married with 1 adult child and 2 grandchildren in the home. Wife prepares most meals, traditional Mexican cuisine and he takes a prepared lunch when on the job as a construction worker.

He is struggling to complete his tasks at work due to fatigue. He has not noticed a change in appetite, although some foods don’t taste as good. Although he has some missing teeth, he reports that this does not affect his choice of foods or ability to eat. He does experience constipation more frequently. His diet is low in fiber and he indicates that he is more inactive or sedentary now then what just a year ago.

Although he had not been accustomed to taking medications, his list now includes a diuretic, anti- hypertensives, statin, and sodium bicarbonate. He says he was advised by his primary care physician to decrease salt intake his diet but his wife has struggled to adjust her cooking to restrict use of salt.

Paper for above instructions

1. What is CKD?

Chronic Kidney Disease (CKD) is a condition where the kidneys gradually lose their ability to function over time, which can lead to serious health problems. In simple terms, your kidneys are important organs that filter waste and extra fluids from your blood. When they don't work as well as they should, waste can build up in your body, and this can affect other organs, like your heart. It is essential to manage this condition to keep your kidneys functioning for as long as possible and to avoid complications (1).

2. Calculating GFR and Understanding Dialysis

A) To calculate Juan’s estimated glomerular filtration rate (GFR), we use the Modification of Diet in Renal Disease (MDRD) equation. Juan's serum creatinine level is 2.4 mg/dL, and he is 67 years old, with a normal GFR considered ≥60 mL/min.
For a male:
\[ GFR = 186 \times (Serum\ Creatinine)^{-1.154} \times (Age)^{-0.203} \]
\[ GFR = 186 \times (2.4)^{-1.154} \times (67)^{-0.203} \]
Calculating the above expression yields a GFR of approximately 28 mL/min, indicating Stage 4 CKD (2). This significantly low GFR suggests progression to end-stage renal disease, which may necessitate dialysis (3).
B) Dialysis is a medical treatment that performs the critical functions of the kidneys when they fail. It helps to remove waste materials and excess fluid from the blood, which your kidneys can no longer do. It's important to consider dialysis for Juan, as it can help manage symptoms of CKD, such as fatigue or confusion, by regulating waste build-up (4). There are two types: hemodialysis, which filters blood through a machine, and peritoneal dialysis, which uses the lining of the abdomen.

3. Micronutrients of Greatest Concern in CKD

| Micronutrient | Condition(s) of Deficiency or Potential Toxicity Concern |
|-------------------|-----------------------------------------------------------|
| Phosphorus | Hyperphosphatemia leading to bone and cardiovascular issues |
| Potassium | Hyperkalemia leading to cardiac arrhythmias |
| Calcium | Hypocalcemia leading to weak bones |
| Vitamin D | Deficiency leading to bone weakness and mineral disorders |
| Iron | Anemia (due to decreased erythropoietin production) |
These micronutrient concerns arise from altered metabolism and dietary restrictions associated with CKD (5, 6).

4. Dietary Supplements

A) Yes, Juan may need to take dietary supplements. Recommended micronutrients and dosages include:
- Sodium Bicarbonate: 650 mg twice daily to help manage metabolic acidosis (7)
- Calcium carbonate: 500 mg with meals to address calcium levels (8)
- Vitamin D: 800-1000 IU daily to promote calcium absorption (9)
- Iron Supplement: Ferrous sulfate at 325 mg/day as needed based on lab values.
B) Juan requires sodium bicarbonate supplements because they help correct the acidosis that can develop with kidney disease. This is essential to maintain a normal blood pH and decrease complications associated with CKD (10).

5. Non-Dietary Lifestyle Modifications for Juan

1. Routine Medical Check-ups: Regular visits with healthcare providers to monitor kidney function and adjust treatments as necessary.
2. Exercise: Encouraging moderate physical activity suitable for his ability, which helps improve energy levels and overall health.
3. Weight Management: Focusing on gradual weight loss if overweight can alleviate strain on the kidneys and improve metabolic health.
4. Stress Management: Implementing stress-reduction strategies, such as counseling or lifestyle changes, to help improve both mental and physical well-being (11).

6. Dietary Considerations and Meal Planning

A) To calculate Juan’s daily energy requirement, we can use the Mifflin-St Jeor equation:
For men:
\[ BMR = 10 \times weight(kg) + 6.25 \times height(cm) - 5 \times age(y) + 5 \]
Juan's weight is 155 lb (~70.3 kg), height is 67 inches (~170.2 cm).
Calculating BMR:
\[ BMR = 10 \times 70.3 + 6.25 \times 170.2 - 5 \times 67 + 5 = 1532.96 \, \text{kcal/day} \]
Assuming a sedentary activity level, we multiply BMR by 1.2.
\[ Total \, Caloric \, Needs = 1532.96 \times 1.2 \approx 1839.55 \, \text{kcal/day} \]
B) Juan's estimated daily fluid intake can be determined based on his stage of CKD, typically suggested to be around 1 liter or adjustments based on residual kidney function and edema (12). Given his condition, advising water intake should be around 1-1.5 L per day but should be tailored based on his clinical presentation.
C) Here’s a two-day menu to assist Juan’s dietary needs.
| Meal | Foods | Notes |
|------------|--------------------------------------------------------------|---------------------------------|
| Day 1 | | |
| Breakfast | Scrambled egg (2) with tomatoes (LS); Whole wheat toast (DF) | |
| Snack | Apple slices (DF) | |
| Lunch | Grilled chicken (SR), quinoa (DF), steamed broccoli (DF) | |
| Snack | Carrot sticks (DF) | |
| Dinner | Baked fish (SR), brown rice (DF), salad with vinaigrette | |
| | | |
| Day 2 | | |
| Breakfast | Oatmeal with blueberries (DF); Almond milk (LS) | |
| Snack | Banana (DF) | |
| Lunch | Lentil soup (DF, SR); Whole grain roll | |
| Snack | Celery with hummus (DF) | |
| Dinner | Stuffed bell pepper with ground turkey (LS, SR) | |
This comprehensive dietary approach addresses Juan’s CKD while considering his cultural preferences (13).
