Diet treatment in liver cirrhosis - di Vincenzo Ostilio Palmieri

  1. 1. Diet treatment in liver cirrhosis
  2. 2. Nutrition : Ingestion, digestion, absorption andassimilation of a nutrionally balanced and adequate diet is necessary to maintain good health. An imbalance between nutrientintakes and requirements can lead tomalnutrition manifested by alternation in metabolism,organ function and .body composition
  3. 3. :Malnutrition May beSpecific mineral and micronutient deficiency such (1 as vitamin (A, B, C, D, E, K) and Cu, Fe, I, Se, .Zn deficiency Protein-energy malnutrition (PEM) 2)
  4. 4. PEM:Common in patients with chronic.liver diseasesHowever the criteria used to diagnose PEMare affected by liver disease itself, so thepresence and severity of malnutrition isoften related to clinical stages of liverdiseases i.e. malnutrition increases with.worsening of liver functionsPEM is almost a universal finding in patients. awaiting liver transplantation
  5. 5. Although indicators of nutritional status donot necessarily reflect adequacy ofnutrient intakes, these can be useful forprognostic assessments of clinical.outcomes in patients with liver diseases
  6. 6. PEM IN CHRONIC LIVERDISEASES Associated withAn increased risk of infection leading to inhibition of (1 albumin synthesis (through the inhibitory effect of(.interleukein-1 & TNF .Multiple organ complications( 2Esophageal variceal haemorrhage. 3(Increased mortality before transplantation.(4Increased risk of infection, prolonged hospitalisation and ( 5. mortality after transplantation .Increased incidence of encephalopathy( 6
  7. 7. liver cirrhosis Compensated form Uncompensated form Adequate detoxifying Ascites, oedema, .activity loss of muscle mass, .No ascites bleeding oesophageal No bleeding tendency varices, hepatic and encephalopathy,.No hepatic encephalopathy bleeding tendency and progressive deterioration in .laboratory test results
  8. 8. Causes of malnutrition in cirrhosis
  9. 9. The importance of correct diet in cirrhosis ofthe liver is unfortunately still underestimated. ”A “liver-adapted .diet is just as important as medication
  10. 10. Indications for starting dietetic treatment Dietetic treatment becomes necessary when there are signs of malnutrition or adequate nutrition is no longer . possible using ordinary means :Signs of malnutrition include • Loss of muscle mass. • Loss of subcutaneous adipose tissue. • Increase in tissue water.
  11. 11. The measures in dietetic treatment are Assuring the adequate intake of protein and . correct types of proteins . Assuring an adequate supply of energy . Increased dietary intake of fibre Administration of branched-chain amino . acids . Reduced intake of sodium .Restriction of fluid . Increased intake of potassium
  12. 12. The goals of dietetic treatment are . Preventing or remedying malnutrition . Improving liver functionAvoiding catabolic states (increased breakdown of the body’s own protein(, which may trigger hepatic encephalopathy Improving protein metabolism, especially in patients requiring reduced protein diets, by providing increased amounts of branched chain amino acids. Management of ascites and edema by a low sodium diet, fluid restriction, and a plenty .supply of potassium
  13. 13. As long as the liver fulfils its functions(compensated type of cirrhosis of the liver), . no dietetic treatment is requiredPatients should maintain a healthy diet, preferablytaking six small meals distributed throughout the .day, and absolutely avoid alcohol In no case should protein intake be restricted, because, in doubtful cases, this will only be .harmful Daily protein intake should be .about 1.2 g per kg body weight
  14. 14. In uncompensated liver cirrhosis, it is important to assure that the patient is getting the required amounts of nutrition. Often, due to poor appetite and satietye.g. due to ascites), weakness and fatigue, )dietary intake is inadequate. Also, the poor taste of hospital food or of a low-sodium diet may cause patients not to take .adequate nutrition
  15. 15. There should be no automatic decision toput patients on a reduced protein diet even .in uncompensated liver cirrhosisOn the contrary, these patients, who are often affected by a significant protein and energy deficit, should actually be taking 1.5 g ofprotein per kg each day, or about 100-120 g of .protein per day in most cases This corresponds to an ordinary diet in healthy persons, with adequate amounts of fruit, vegetables, salads, whole grain .products, potatoes, rice and pasta
  16. 16. Experts recommend the following :protein intakes 1.2 g of protein per kg body weight each day in compensated liver cirrhosis. 1.5 g of protein per kg body weight each day in uncompensated liver cirrhosis and malnutrition.
  17. 17. Physicians are often concerned that an adequateprotein intake may trigger hepatic encephalopathy. This is the “protein dilemma” in which adequate protein is good for malnutrition but bad for encephalopathy and vice-versa. This dilemma, however, does not apply in 99% of patients with liver cirrhosis, in whom other triggers such asinfection, bleeding, drugs, renal failure, electrolyte imbalance and constipation are present.
  18. 18. Beside the amount, the qualityof protein also is important. This is especially true for all sick persons and very much so for persons with liver diseases.
  19. 19. An imbalance in amino acids does not occur solely after such bleeding, but actually occurs in all cirrhosis patients as a consequence of disturbed liver function and the de-tour of portal bloodthrough the collateral circulation. Patients with cirrhosis are deficient in branched- chain amino acids (BCAA(, but have an excess of aromatic amino acids (AAA(.
  20. 20. • BCAA • AAA Metabolism independent Metabolism dependent on liver function. on liver function Predominantly in the Predominantly in the musculature. Liver. Blood level reduced Blood level increased .in cirrhosis .in cirrhosis Useful in Unfavorable in :encephalopathy :Encephalopathy valine, leucine and tyrosine, phenylalanine .isoleucine .and methionine The level of waste products of BCAA does not increase as a result oftheir being broken down. BCAA also inhibit the breakdown of protein
  21. 21. Poor tolerance • Aromatic amino acids (AAA) Blood Meat/sausage Fish/egg Milk/dairy products Vegetable protein • Branched-chain amino acids (BCAA)Good tolerance
  22. 22. Energy requirement Normal weightheight in centimeters minus 100( times 35 = ( energy requirement in kilocalories per day. This calculation considers the energycontent of all foods, including that of dietary protein, which is not primarily used as a .source of energy
  23. 23. Carbohydrates are the main source of energy for the body. Like fat they do not raise the levels of toxins in the body. 1 g of carbohydrate provides the body with 4 kilo-calories (kcal(. Foods that are richin carbohydrate include: sugar, sweets, fruit, bread, foods made with flour, .potatoes, milk and vegetables
  24. 24. ” Roughage reduces the “toxin level Non-digestible roughage is also classed among the carbohydrates. Roughage )orfiber) consists of those parts of vegetable foodstuffs that cannot be utilized by the .human bodyRoughage promotes digestion, slows the rise in blood sugar, reduces the level of cholesterol .and improves the sensation of satiety For patients with cirrhosis of the liver it is of particular importance that it .binds toxins in the bowel
  25. 25. A high-fiber diet often has side effects)bloating, sensation of fullness ).or abdominal pain
  26. 26. Fats Fat does not increase toxic levels of ammonia in hepaticencephalopathy. It is used as a source of energy and as an energy store. The intake of animal fats should not be too high and the intake of vegetable fats should not be too low. In about 40% of the patients suffering from cirrhosis of the liver the digestion of fats is disturbed because ofpoor fat utilization and absorption. This may also affect the absorption of fat-soluble vitamins (A, D, E and K), which may lead to deficiency and must be supplemented parenterally in these patients. In steatorrhea, special fat)MCT-fat) can be used. MCT is the abbreviation for medium chain triglycerides. “Ceres MCT Diet Cooking Oil” from Special MCT fats, such as margarines, oil and special dietetic MCT foods such as soft cheese, hazelnut nougat crème etc.,
  27. 27. Minerals, vitamins and water
  28. 28. Sodium All patients with cirrhosis should, as a rule, be advised to use less salt in order to inhibit the development .of ascites or edema :Sodium-defined diets• Strict low sodium diet (1 g of table salt per day)• Low sodium diet (3 g of table salt per day)• Sodium-reduced diet (6 g of table salt per day)
  29. 29. Potassium Salt substitutes generally contain potassium in place of sodium compounds. In addition to an improvement in taste, they have the advantage of the high potassium content. A potassium-rich diet is particularly important for patients who take diuretics to get rid of fluid, as potassium deficiency can otherwise occur.Particularly rich in potassium are all types of vegetables (particularly cabbage, potatoes, herbs, tomatoes, spinach, tomato pulp, mushrooms and chanterelles(, fruit
  30. 30. Patients with cirrhosis of the liveroften show a deficiency in minerals )zinc, iron, calcium,) and vitamins A, D, E, K, folic acid, B1, B2, B6,)B12). Supplementation in the form of tablets, capsules or drops is much easier than the demonstration of a .deficiency
  31. 31. Many patients with cirrhosis of the liver suffer from a marked zinc deficiency. , When zinc is given in tablet form hepatic encephalopathy often . improvesParticularly good here are zinc tablets containing organic zinc compoundssuch as zinc histidine, which are more reliably absorbed from the bowel than . inorganic zinc salts
  32. 32. :Supply of fluid A restriction in the amount of fluid is onlyrequired if the level of sodium in the blood is toolow or in case of oedema or ascites.The amount consumed should be reduced to 500–1000ml.When the fluid intake is low, only drinks that quench thethirst should be chosen.Milk, mixed drinks, sweetened soft drinks or teas, andhigh sodium mineral waters are not appropriate.Mineral water, which is also used to supply the calciumrequirement, is thirst quenching.
  33. 33. :Soft diet The importance of soft or strained foods in the prophylaxis of variceal bleeding has not been proven.What is certain is that sufficiently small, careful chewed and well moistened foods are better tolerated and more efficient.In all disorders of the oesophagus, one should consider the temperature (lukewarm is best, avoid very hot or very cold) and aggressiveness (acid, hot spices) in food.
  34. 34. Summary
  35. 35. There is no absolute restriction in diet for patients with liver diseases and in general, they should followthe principles of a balanced, healthy . diet , It is essential, however that patients with diseases of liver.absolutely avoid alcohol in any form
  36. 36. ,No alcohol otherwise .moderately Not more than .low-fat portion 2–1 At least .portions 3 At least 4!Drink at least 2 liters daily .portions !Salt moderately
