Protein requirements in maintenance hemodialysis
The American Journal of Clinical Nutrition
|October 1, 1978
Summary
Protein needs for hemodialysis patients are higher than previously thought. Current recommendations should increase to 1.2 g/kg, alongside adequate calorie intake, to ensure optimal nutritional status for dialysis patients.
Area of Science:
- Nephrology
- Nutritional Science
- Clinical Nutrition
Background:
- Protein requirements for maintenance hemodialysis patients remain uncertain.
- Previous recommendations of 1 g/kg body weight, primarily high biological value protein, are now considered insufficient based on recent studies.
Purpose of the Study:
- To define precise protein requirements for maintenance hemodialysis patients.
- To evaluate the impact of a specialized protein mixture on nutritional status.
Main Methods:
- A controlled study was conducted to assess protein needs.
- Patients received 1 g/kg of protein intake with standard dialysis (approx. 20 hr/week).
- Supplementation with a special protein mixture was evaluated.
Main Results:
- The study suggests that 1.2 g/kg of body weight, primarily high biological value protein, is a more appropriate recommendation.
- An intake of 35 kcal/kg body weight is also advised for dialysis patients.
- Additional protein supplementation is necessary during complications like bleeding or infection.
Conclusions:
- Maintenance hemodialysis patients require higher protein intake than previously recommended.
- Optimal protein and calorie intake are crucial for managing nutritional status in dialysis patients.
- Individualized adjustments are needed for patients experiencing stress or complications.
