Nutritional Intervention in Chronic Liver Failure.

Area of Science:

• Hepatology
• Clinical Nutrition
• Gastroenterology

Background:

• Chronic liver failure (CLF) patients frequently experience malnutrition, characterized by inadequate nutrient intake, particularly protein.
• Low protein intake and muscle wasting (sarcopenia) are significant indicators of poor prognosis in CLF.
• Hepatic glycogen stores are diminished in CLF, increasing susceptibility to muscle protein breakdown during fasting.

Purpose of the Study:

• To highlight the critical role of nutritional assessment and intervention in managing patients with chronic liver failure.
• To provide evidence-based recommendations for optimizing protein and energy intake in CLF.
• To emphasize the importance of preventing muscle loss and refeeding complications.

Main Methods:

• Screening CLF patients for malnutrition risk using validated tools.
• Conducting comprehensive nutritional status assessments, including sarcopenia evaluation.
• Implementing tailored nutritional interventions, ranging from counseling to specialized feeding methods.

Main Results:

• Recommended protein intake of 1.2-1.5 g/kg/day and energy intake of 30 kcal/kg/day (1.3x resting energy expenditure).
• Advocating for avoidance of prolonged fasting (>12 hours) to prevent muscle catabolism.
• Suggesting late-evening snacks or nocturnal supplements to maintain protein status.

Conclusions:

• Early identification and management of malnutrition and sarcopenia are essential for improving outcomes in CLF.
• Personalized nutritional strategies, including adequate protein and energy, are vital for CLF patient care.
• Preventing complications like refeeding syndrome and nutrient deficiencies is a key component of nutritional support in CLF.
