What is the pathophysiology of liver disease?

The necrosis of hepatocytes stimulates immune cells to release cytokines, growth factors and various unknown chemicals. These chemical messengers direct hepatic stellate cells (support cells in the liver) to activate and produce collagen, glycoproteins (such as fibronectin) and proteoglycans among other substances.

What is the pathophysiology of liver cirrhosis?

Pathogenesis and pathophysiology of cirrhosis Fibrosis describes encapsulation or replacement of injured tissue by a collagenous scar. Liver fibrosis results from the perpetuation of the normal wound healing response resulting in an abnormal continuation of fibrogenesis (connective tissue production and deposition).

What is the pathophysiology of alcoholic liver cirrhosis?

Pathology of Alcoholic Liver Disease Hepatic steatosis is potentially reversible. Macrovesicular fat accumulates as large droplets of triglyceride and displaces the hepatocyte nucleus, most markedly in perivenular hepatocytes. The liver enlarges.

What is liver pathology?

Liver pathology includes ultrastructural changes, steatosis, and mild inflammation at early stages (~6weeks of age), followed by hepatitis, dysplasia, and necroinflammation in advanced stages (at ~12–20 weeks of age).

What is the best medicine for liver disease?

Milk thistle (silymarin) is the most widely used and best studied. However, there is not enough evidence of benefit from clinical trials to recommend use of any herbal products to treat liver cirrhosis. In addition, some alternative medications may harm the liver.

What are the signs of chronic liver disease?

Symptoms may include:

• Fluid buildup in the belly (ascites)
• Vomiting blood, often from bleeding in the blood vessels in the food pipe (esophagus)
• Gallstones.
• Itching.
• Yellowing of the skin and eyes (jaundice)
• Kidney failure.
• Muscle loss.
• Loss of appetite.

What is the best treatment for liver cirrhosis?

The main treatment for primary biliary cirrhosis is to slow liver damage with the drug ursodiol (Actigall, Urso). Ursodiol can cause side effects like diarrhea, constipation, dizziness, and back pain.

What are 3 important functions of the liver?

Functions of the liver

• Production of bile, which helps carry away waste and break down fats in the small intestine during digestion.
• Production of certain proteins for blood plasma.
• Production of cholesterol and special proteins to help carry fats through the body.

What are signs your liver is bad?

Signs and symptoms of acute liver failure may include:

• Yellowing of your skin and eyeballs (jaundice)
• Pain in your upper right abdomen.
• Abdominal swelling (ascites)
• Nausea.
• Vomiting.
• A general sense of feeling unwell (malaise)
• Disorientation or confusion.
• Sleepiness.

What are the 3 stages of alcoholic liver disease?

Alcoholic liver disease is defined by three stages of liver damage following chronic heavy alcohol consumption: fatty liver, alcoholic hepatitis, and fibrosis/cirrhosis (Figure 5).

What functions does the liver have?

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.

What kind of liver diseases are there?

There are many kinds of liver diseases:

• Diseases caused by viruses, such as hepatitis A, hepatitis B, and hepatitis C.
• Diseases caused by drugs, poisons, or too much alcohol. Examples include fatty liver disease and cirrhosis.
• Liver cancer.
• Inherited diseases, such as hemochromatosis and Wilson disease.

What should a pharmacist know about liver cirrhosis?

Pharmacists should be cognizant of recommended drug-dosing alterations for patients with cirrhosis that are necessitated by decreased hepatic and/or renal function. Liver cirrhosis is the end result of several mechanisms of liver inflammation caused by chronic liver disease, genetic disease, or autoimmune inflammation.

What is the pathophysiology of chronic liver disease?

HPS is defined by the presence of chronic liver disease; abnormal arterial oxygenation or an arterial partial pressure of oxygen in the absence of an alternate cause; and evidence of intrapulmonary vascular dilatations (IPVDs) [7] Hepatopulmonary syndrome occurs mostly in patients who have established cirrhosis and portal hypertension [8].

Which is the most common cause of liver failure?

Chronic liver failure is caused by excessive alcohol intake, Hepatitis B or C, malnutrition, Hemochromatosis (body absorb and store too much iron) and cirrhosis (irreversible inflammatory disease) [2]. Figure 1 show the stages of liver damage which eventually lead to cirrhosis.

Can a pharmacist treat drug induced liver injury?

Management of DILI involves the removal of the offending agent and the use of N -acetylcysteine for acetaminophen-induced liver injury. Outcomes vary depending on the drug used and type of liver injury sustained. Pharmacists can play an essential role in the evaluation of DILI, especially in patients taking multiple medications and supplements.
