Diagnosis• Cirrhosis
– 12th leading cause of death in the U.S.– Ending stage of liver disease– Secondary to chronic hepatitis C– Replacement of healthy liver tissue with
scar tissue– Blocks the flow of blood through the
liver, causing kidney failure, enlarged liver, thickening of various tissues, portal hypertension, ascites, etc.

Etiology• Common causes of cirrhosis:
– Alcohol-related liver disease– Chronic hepatitis C– Chronic hepatitis B– Autoimmune hepatitis– Nonalcoholic fatty liver disease (NAFLD)– Bile duct disorders– Hereditary disorders
![Page 13: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/13.jpg)

Complications & Warning Signs
• Edema &Ascites• Bruising and bleeding• Portal hypertension• Esophageal varices• Jaundice• Hepatic encephalopathy• Insulin resistance and type II
diabetes
![Page 15: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/15.jpg)
15
Ascites
![Page 16: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/16.jpg)
16
Diagnosing Cirrhosis• Look at the clinical signs &
symptoms• Biopsy, CT Scan, and MRI may reveal
an enlarged liver, reduced blood flow, and /or ascites– Biopsy’s are less common because it it
expensive, and usually only confirms a diagnosis
![Page 17: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/17.jpg)
17
Diagnosing Cirrhosis• Blood tests to measure:
– Measures function of the liver– Albumin– Bilirubin– PT (Prothrombin Time)
• Liver enzymes:– Measures injury to the liver– ALT– AST
![Page 18: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/18.jpg)
18
Severity• MELD
– Model for end-stage liver disease– 6 - 40 score range—6 is a likelihood that
patient will survive 90 days– Score comes from:
• Bilirubin count—measures bile pigment in the blood
• Creatine levels—tests kidney function• INR (international normalizes ratio)—tests
blood clotting tendency

Treating Cirrhosis• Primary medical treatments for
cirrhosis:– Preventing further damage– Treatment of the complications – Liver transplant– Nutrition therapy
![Page 20: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/20.jpg)
20
Treating Cirrhosis• Preventing further damage:
– The first thing doctors will recommend is abstaining from alcohol and any drugs that will damage the liver further
– Consume a balanced diet and a multivitamin may be recommended (D and K especially)
– Avoid nonsteriodalantinflammatory drugs (NSAIDS)• Ibuprofen
![Page 21: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/21.jpg)
21
Treating Cirrhosis• Treating complications:
– Ascites• Antidiuretics
– Bleeding from varices• Beta-blockers• Propanolol
– Hepatic Encephalopathy• Laxatives (lactulose)
![Page 22: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/22.jpg)
22
Treating Cirrhosis• Liver Transplant:
– Cirrhosis in irreversible, and many patients will eventually need a liver transplant as the only option left
– 80% of patient live for 5 years after surgery
![Page 23: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/23.jpg)

Energy & Protein• Ms. Wilcox’s energy needs:• Weight: 56.8 kg• 35 x 56.8= 1,988 calories• 40 x 56.8= 2,272 calories
– 2,000-2,200 calories/day. • Ms. Wilcox’s protein needs:• 1.6 x 56.8=90.8
– ~ 91 g protein/day
![Page 25: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/25.jpg)
25
Nutrition Problems–Inadequate energy intake: NI-
1.4–Inadequate oral intake: NI-2.1–Malnutrition: NI-5.2–Inadequate protein-energy
intake: NI-5.3–Underweight: NC-3.1
![Page 26: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/26.jpg)
26
PES Statements– Inadequate energy intake related to
decreased appetite, fatigue, and nausea by recent cirrhosis of the liver dx as evidenced and diet recall
– Underweight related to decreased appetite in past three weeks as evidenced by diet recall, recent 10 lb weight loss, and BMI of 18.5 kg/m^2
![Page 27: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/27.jpg)
27
Nutrition Intervention & Support
• Small frequent feedings• Encourage oral liquid supplements• High kcal and protein diet• Restrict sodium intake to ≤ 2-g• Abstain from alcohol consumption• Provide foods that are easy to chew and
swallow• Optimize gastric emptying
– Avoid excessive fiber– Control blood glucose– Liquids over solids if necessary
![Page 28: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/28.jpg)
28
Prognosis• Depends on stage of the disease• Once the liver has scarred over, it
cannot be reversed, meaning it cannot return to its normal function
• Survival is generally 10 years after dx (90%)
• Complications of ascites, portal hypertension, jaundice, hepatorenal syndrome, hepatic encepalopathy, etc.
• Liver transplant will most likely be needed as a result of cirrhosis
![Page 29: Cirrhosis of the Liver with Resulting Hepatic Encephalopathy](https://reader036.fdocuments.in/reader036/viewer/2022081512/56815f63550346895dce5221/html5/thumbnails/29.jpg)
29
Prognosis:Stages of Cirrhosis• Stage 1
– Patients without gastro-esophageal varices or ascites have mortality of ~1% per year
• Stage 2– Patients with gastro-esophageal varices but
no ascites have mortality of ~4% per year• Stage 3
– Patients without gastro-esophageal varices but have ascites have mortality rate of ~20% per year
• Stage 4– Patients with GI bleeding from portal
hypertension with/without ascites have mortality of ~57% per year
