20 Malnutrition in Liver Cirrhosis Effect of Tube Feeding Bilirubin Encephalopathy Wochen Controls 0.78 g protein kg-1 d-1 Tube feeding 1.81 g protein kg-1 d-1 Kearns et al, Gastroenterology 1992, 102:

21 Nutrition in Liver Cirrhosis ESPEN Guidelines Ensure adequate energy intake 1.3 x REE or 25 NP-kcal kg -1 d -1 Provide enough protein!! g kg -1 d -1 Use fat 1.0 g kg -1 d -1 Special products BCAA-enriched solutions Oral BCAA supplements HE III -IV Protein intolerance Malnourished children Plauth et al, Clinical Nutrition 1997, 16:43-55

22 BCAA in Liver Cirrhosis Attenuation of Loss of Hepatic Function double-blind randomized study, three arms 14.4 g BCAA daily 14.4 g Maltodextrin (M-DXT) 12.6 g Lactalbumine (L-ALB) each for 52 weeks BCAA (vs M-DXT und L-ALB) less hospital admissions shorter hospital stay Marchesini et al, Gastroenterology 2003, 124:

23 BCAA in Liver Cirrhosis Effects on Event-Free Survival Event-free survival [%] Prospective multi-centre study, 24 months, 12 g BCAA vs normal oral diet Primary end point: event-free survival (Death from any cause, HCC, variceal bleed, deterioriation of hepatic function) 100 Logrank Test p=0.015 Hazard Ratio VKAS (n=314) Diät (n=308) Days after start of treatment Muto et al, Clin Gastroenterol Hepatol 2005, 3:705-13

24 BCAA in Liver Cirrhosis ESPEN Guidelines 2006 How should enteral nutrition be delivered? -which formula? Polymeric enteral formulas (sip feed or tube formula) are generally recommended. Diets with a high energy density are preferable in ascites patients for reasons of fluid balance (C). In case of hepatic encephalopathy arising during recommended protein intake the nitrogen intake goal can be achieved by using BCAA-enriched formulas (A). Oral BCAA supplementation may improve clinical outcome in advanced cirrhosis (B). Plauth M et al, Clin Nutr 2006, 25:

25 Hepatic Encephalopathy Protein Restriction is not Advantageous! Encephalopathy grade 4 Protein restriction No protein restriction day 0 day 7 day 14 Córdoba et al, J Hepatol 2004, 41:38-43

32 Feeding Malnourished Cirrhotics Vitamine, Trace Element, Mineral Deficiencies Phosphate Vitamine B 1 Other vitamines Zinc Refeeding syndrome i.v. glycerophosphate 15 mmol PO i.v. in 2 h (maximum 45 mmol/24h) Lactic acidosis, Wernicke s encephalopathy prophylaxis 250 mg/d i.m./i.v. for 3-5 days Deficiency frequent in (alcoholic) cirrhosis oral supplement Impairment of ureagenesis, protein synthesis, glucose disposal 80 mg Zinc (200 mg ZnSO 4 ) t.i.d. Rosen GH et al, Crit Care Med 1995, 23: Sechi & Serra, Lancet Neurol 2007, 6: Marchesini et al, Hepatology 1996, 23: and Metabolism 1998, 47:792-8

33 Feeding the Critically Ill Cirrhotic Summary Expect severe malnutrition requiring immediate treatment Protein malnutrition and hypermetabolism are associated with a poor prognosis Ensure adequate energy intake (non protein 25 kcal kg -1 d -1 ) Use indirect calorimetry if available Provide enough protein ( g kg -1 d -1 ) Use BCAA after GI-bleeding and in HE III /IV Use fat as fuel (recommended fatty acid ratio n6:n3 = 2:1) Use enteral tube or sip feeding Use parenteral nutrition if enteral alone is not sufficient Avoid refeeding syndrome or vit./trace el. deficiencies How to feed critically ill cirrhotics? Like other critically ill patients with severe malnutrition!
