Introduction:
Chronic hepatocellular failure is characterized by a steady decline in liver activity over six months. These processes include the production of clotting factors, the excretion of bile, and the detoxification of toxic metabolic byproducts. The structure of the liver is disrupted in the final stage of hepatocellular failure, which is known as cirrhosis. Chronic liver failure, or hepatocellular failure, is a widespread clinical condition with a significant etiology of alcohol consumption for more extended periods, infection, autoimmune diseases, and genetic and metabolic disorders.
What Is Chronic Hepatocellular Failure?
The liver is the largest internal organ with hepatic cells. It primarily resides in the upper right quadrant of the abdomen, just above the stomach. The liver metabolizes fats, proteins, and carbohydrates and excretes bile, cholesterol, hormones, and drugs. Any damage to the liver as a result of viruses, drugs, or alcohol leads to disruption in liver function. This is called chronic hepatocellular or liver failure, a life-threatening condition. In addition, healthy tissue is replaced with scar tissue over time, which typically declines the function of the liver.
What Is the Etiology of Chronic Hepatocellular Failure?
The long-term inflammation that results in the scarring of healthy liver tissues causes chronic liver failure (fibrosis). The causative agent of hepatocellular failure are
-
Alcoholic liver disease.
-
Non-alcoholic fatty liver disease (NAFLD).
-
Chronic viral hepatitis C infection.
-
Autoimmune hepatitis (AIH).
-
Genetic.
Alcoholic Liver Disease: This condition usually develops in patients who consume much alcohol. Alcohol is a toxic compound that has the potential to inflame and enlarge the liver. This harm can eventually result in cirrhosis.
Non-alcoholic Fatty Liver Disease: NAFLD is not caused by alcohol abuse but is associated with underlying conditions such as obesity, hyperlipidemia (increased cholesterol and triglycerides), and diabetes mellitus. It manifests as fatty liver and scarring after many years of severe inflammation.
Chronic Viral Hepatitis C infection: Hepatitis C is a viral infection that can result in severe liver damage by inflaming the liver. The infection spreads through the infected person's blood via needle sharing. Chronic hepatitis C left untreated, may lead to hepatocellular carcinoma or cancer.
Autoimmune Hepatitis: Chronic inflammatory hepatitis, which affects women more frequently than males, is characterized by increased autoantibodies such as antinuclear antibodies (autoantibodies target "normal" proteins found in a cell's nucleus), and hypergammaglobulinemia (increased production of immunoglobulins by plasma cells).
Genetic: The genetic variant involves alpha-1 antitrypsin deficiency, commonly seen in children, and Wilson disease is an autosomal recessive disorder leading to copper accumulation in the liver and other body tissues.
Other Causes: Chemotherapy, chronic right-sided heart failure, hemochromatosis (accumulation of iron in the liver and other organs), bile duct diseases, and Budd-Chiari syndrome, which causes hepatic vein (liver vein) blockage.
What Are the Symptoms of Chronic Hepatocellular Failure?
The common signs and symptoms of chronic hepatocellular failure involve
-
Jaundice (a yellowish discoloration of the skin and eyes).
-
Nausea.
-
Diarrhea.
-
Insomnia.
-
Disorientation.
-
Fatigue.
-
Loss of weight.
-
Edema of the legs and abdomen.
-
Spleen enlargement.
-
Internal bleeding (stomach).
-
Kidney failure.
-
Rarely liver cancer.
How to Diagnose Chronic Hepatocellular Failure?
The diagnosis is based on etiology, history of alcohol abuse, genetics, and other disease complications. The significant modalities of diagnosis are blood screening, radiological investigations, and biopsy.
Blood Screening: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels are elevated in chronic liver illness due to hepatocyte breakdown and inflammation. Liver function test (LFT) measures also rose significantly. Cirrhosis manifests with a standard range of LFTs, a decrease in albumin levels, and an increase in ammonia, which leads to hepatic encephalopathy.
Radiologic Findings: It involves ultrasound, CT scan, transient elastography, fibroscan, hepatic wedge pressure, endoscopy, EEG, TIPS, triphasic CT, and doppler scan.
-
Ultrasound: Ultrasound of the abdomen determines the liver's size, echogenicity, and nodularity. Additionally, measure the portal vein's diameter as it grows in portal hypertension and evaluate a clot in the hepatic vein (Budd-Chari).
-
Computed Tomography (CT): Detects hepatocellular cancer, liver abnormalities, and blockage of biliary channels more precisely.
-
Transient Elastography (TE): Evaluate early cirrhosis. Additionally, it can spot cardiovascular impairment in non-alcoholic fatty liver disease patients.
-
Wedge Pressure: The wedge hepatic venous pressure measures the portal venous pressure in chronic liver disease.
-
Doppler scan: Assist Budd-Chiari and portal vein thrombosis.
-
EEG (electroencephalogram): Hepatic encephalopathy is characterized by EEG delta waves.
Biopsy: A biopsy is frequently used as a diagnostic to identify liver damage. A small portion of the liver is removed by surgery and examined in a laboratory.
What Are the Treatment Options for Chronic Hepatocellular Failure?
The treatment options are based on the stage and severity of the failure. Unfortunately, a liver transplant is necessary in severely damaged cases and those with alpha-1-antitrypsin deficiency. Corticosteroids and other immunosuppressive drugs are recommended in autoimmune hepatitis. Iron and copper chelators are indicated for hemochromatosis and Wilson disease. Anticoagulation, thrombolysis, or angioplasty are the treatment options for Budd-Chiari syndrome.
What Is the Prognosis of the Treatment?
A compensated chronic liver disease without significant complications has a better prognosis than decompensated liver cirrhosis with the associated symptoms of hepatorenal syndrome (decreased urination or disrupted kidney activity and increased nitrogen in the blood), ascites, and variceal hemorrhage (gastrointestinal tract bleeding).
What Is the Complication of Chronic Hepatocellular Failure?
The common complications of chronic. hepatocellular failure
-
Variceal bleeding.
-
Ascites
-
Hepatic encephalopathy (Inadequate liver function causes toxins to accumulate in the blood. These toxins can reach the brain and impact memory).
-
Hepatorenal syndrome.
-
Hepatopulmonary syndrome (lung expansion along with liver disease).
-
Hepatocellular carcinoma (HCC).
How to Prevent Chronic Hepatocellular Failure?
Chronic hepatocellular failure can be avoided by abstaining from alcohol and adhering to a diet plan. Unprotected sexual contact might lead to hepatitis C; therefore, make sure to practice safe sex with infected individuals. Additionally, it is advised to avoid sharing needles and tattoo equipment, which have a higher incidence of hepatitis C transmission. Finally, maintaining blood pressure, blood sugar, and cholesterol levels reduce the risk of hepatocellular failure.
Conclusion:
According to a recent study, 5.5 million patients worldwide suffer from chronic liver disease (CLD), and up to 40,000 people might pass away from the disease's complications or natural progression. Even though liver transplantation can significantly increase the survival and quality of life for patients with advanced CLD. Patients who are liver transplant candidates should be closely watched by the liver transplant team. Regular blood tests, endoscopies, and ultrasounds as needed are necessary. The prognosis and result are better the earlier signs and symptoms of a complication are diagnosed.
