Study Notes
MNT for Hepatobiliary and Pancreatic Disorders
- Includes disorders like hepatitis, alcoholic liver disease, gallbladder disease, and pancreatic disease.
- Liver is the largest organ with varied and numerous functions, including nutritional metabolism. A diseased liver can increase in size and become palpable.
- Liver functions include bile production, detoxification, carbohydrate metabolism, protein metabolism, fat metabolism, vitamin and mineral storage, and filtering bacteria.
- Hepatitis is inflammation of the liver with various causes: viral infections (HAV, HBV, HCV, HDV, HEV), accumulation of fat (NAFLD, NASH), and toxins (alcohol).
- Symptoms of hepatitis can be categorized as primary (e.g., anorexia, malaise, headache) and secondary (e.g., jaundice, hyperbilirubinemia, dark urine, hepatomegaly).
- Alcoholic liver disease affects about 10% of the population. Acetaldehyde is a toxic byproduct of ethanol metabolism.
- Excessive alcohol consumption can lead to hypovitaminemia, decreased vitamin activation, hepatoxicity, inflammation, necrosis, fatty liver, hepatitis, and cirrhosis.
- Alcoholic liver disease has three stages: hepatic steatosis (fatty liver—reversible with abstinence), alcoholic hepatitis (resolution with abstinence, hepatomegaly, abdominal pain), and cirrhosis (repeated necrosis and regeneration, cirrhosis in 15% of heavy drinkers).
- Cirrhosis consequences include portal hypertension, varices (dilated vessels leading to GI bleeding), ascites (fluid in the peritoneal cavity), and jaundice (may or may not be present).
- Portal circulation involves blood flow through the liver. Tributaries of the portal vein are involved in this blood flow.
- Varices are dilated blood vessels, specifically in the esophagus and stomach, likely to bleed due to increased pressure.
- Symptoms of cirrhosis can also include encephalopathy, esophageal varices, portal hypertension, hepatorenal syndrome, tea-colored urine, and clay-colored stool. Other manifestations include icteric sclerae, alopecia, spider angiomas, palmar erythema, gynecomastia, caput medusae, ascites, altered hair distribution, testicular atrophy, edema, jaundice, and bruising.
- ESLD/Hepatic failure is liver failure where the liver function is reduced to less than 25% due to cell loss.
- Acute liver failure is rapid and can be caused by viruses and toxic overdoses.
- Chronic liver failure is progressive.
- Portal systemic encephalopathy (hepatic encephalopathy) is a neuromuscular dysfunction and behavioral alteration caused by liver failure, due to the liver's inability to detoxify ammonia, decreased branched-chain amino acids (BCAAs) increase, and altered metabolism..
- Ammonia detoxification strategies include lactulose, which induces osmotic diarrhea, and neomycin, which destroys ammonia-producing bacteria.
- Nutritional status assessment is sometimes difficult due to altered serum protein indicators, hydration effects on lab results, unreliable weight (ascites, edema), and vitamin/mineral deficiency linked to the liver.
- Subjective global assessment (SGA) utilizes physical signs, symptoms, physiologic stress, and medical history in assessing nutritional status.
- Nutritional management (MNT) aims to maintain or improve nutritional status considering liver disease effects (portal hypertension, ascites, hyponatremia, hepatic encephalopathy, glucose alternations, fat malabsorption, hepatorenal syndrome).
- Alcoholism often results in poor nutritional status, replacing food with alcohol, inadequate oral intake, malabsorption, and altered metabolism.
- MNT for adequate energy involves 25-35 kcal/kg (ABW) or dry weight (20 kcal/kg for obese and 40 kcal/kg for underweight). 1.2 - 1.4 stress factor REE is typically used, but can alter depending on infection or steatorrhea to 1.5 - 1.75.
- Protein MNT involves general protein requirements (1-1.5 g/kg IBW for no encephalopathy, 0.8 - 1.0 g/kg dry weight and 1.2 - 1.3 g/kg for those with increased metabolic stress, sepsis, GI bleed, or ascites). Low protein diets are not recommended for cases of liver encephalopathy.
- Carbohydrate MNT considers hypoglycemia from decreased hepatic glucose production, and hyperglycemia from the metabolism associated with blood glucose levels and diabetes management in the case of liver disease.
- Lipid MNT involves avoiding overfeeding, maintaining 25-40% of kcal from fat (average of 30% ), considering patients with steatorrhea, which may require low-fat diets (less than 40 g of fat) and MCTs (15 ml).
- Vitamin MNT includes thiamine (avoid ETOH due to hindering absorption and conversion of pyruvate to acetyl CoA; high potential for lactic acidosis), folate (decreased intake, poor absorbance), and vitamin B12 (necessary for myelin formation, ETOH interferes with intrinsic factor production, resulting in megaloblastic anemia).
- Fat-soluble vitamin MNT includes supplemental administration due to steatorrhea, and liver associated reduced prothrombin time (PT).
- Mineral MNT is usually administered at times of deficiency and includes supplementation for Fe, Cu, (associated with diseases like hemochromatosis and Wilson's disease), and Zn, Mg, for cases of liver disease, especially from ETOH.
- Electrolyte MNT involves potassium and sodium restriction, in the case of renal function impairment or fluid retention (ascites or edema).
- MNT for acute pancreatitis involves minimal stimulation of pancreatic enzyme secretion, avoiding oral intake, implementing IV hydration, gradually increasing fat intake, and utilizing TPN or TF if necessary.
- Chronic pancreatitis MNT involves small, low-fat meals, pancreatic enzyme replacement (often necessary due to decreased function), and adequate kcal intake.
- Medical management for some cases of chronic pancreatitis may involve surgery (Whipple procedure).
- Biliary dyskinesia is a spasm of the sphincter of Oddi, preventing proper opening and causing pressure build up in the gallbladder.
- Gallbladder disease includes cholelithiasis (gallstones), cholecystitis (inflammation/infection), choledocholithiasis (gallstone blockage of the bile duct), choledochotomy (surgical incision), and cholecystectomy (surgical removal).
- Gallbladder disease includes cholangitis (inflammation of the bile ducts), cholestasis (sludge buildup from lack of bile release), and cholecystitis (inflammation of the gallbladder). MNT for gallbladder disease may involve low fat and monitoring of water and fat soluble vitamins.
