Liver failure is a severe pathological condition characterized by the disruption of all the main functions of the liver. This life-threatening condition develops due to massive damage to hepatocytes, leading to the loss of their ability to perform detoxification, metabolic and synthetic functions. The clinical picture of the disease includes a complex of symptoms caused by the accumulation of toxic substances in the body, disruption of protein, carbohydrate, fat and water-electrolyte metabolism. The acute course can develop rapidly, within a few days or weeks, while the chronic form progresses gradually, over months and years.
History of the disease and interesting historical facts
The study of liver failure began in ancient times, when Hippocrates described "jaundice" as a manifestation of liver pathology. In the 19th century, Rudolf Virchow first systematized pathological changes in the liver in various diseases. An interesting fact is that the first successful liver transplant was performed by Thomas Starzl in 1963, which became a revolutionary breakthrough in the treatment of the terminal stage of the disease. Modern research shows that "According to the European Association for the Study of the Liver, survival after transplantation reaches 75% after 5 years."
Epidemiology
According to the World Health Organization, acute liver failure occurs with a frequency of 1-6 cases per million population annually. The chronic form is diagnosed much more often - about 200-400 cases per 100 thousand population. Statistics indicate the following features of distribution:
- The incidence rate is higher in developed countries due to higher alcohol consumption
- The incidence rate increases after 40 years of age.
- Men suffer more often than women from alcohol abuse
- In developing countries, viral hepatitis remains the leading cause
Genetic predisposition to this disease
Hereditary predisposition to liver failure is associated with mutations in several key genes. Of particular importance are polymorphisms of the cytochrome P450 genes, which affect drug metabolism. Research shows the important role of mutations in the genes:
- CYP2E1 - involved in ethanol metabolism
- UGT1A1 - affects bilirubin conjugation
- PNPLA3 - Associated with Risk of Alcoholic and Non-Alcoholic Steatohepatitis
- HFE - determines predisposition to hemochromatosis
Risk factors for the development of this disease
The development of liver failure can be triggered by various factors of the external and internal environment. The main triggers include:
- Toxic effects (paracetamol, mushroom poisons)
- Chronic alcoholism
- Viral hepatitis B, C, D
- Autoimmune processes
- Metabolic disorders
- Liver congestion in heart failure
Diagnosis of this disease
Clinical diagnostics is based on a comprehensive approach, including various research methods. The main diagnostic criteria are presented in the table:
| Method | Indicators |
|——-|————|
| Lab tests | Increased bilirubin > 3 mg/dL, increased INR > 1.5 |
| Ultrasound of abdominal organs | Enlarged liver, changes in parenchyma |
| Liver biopsy | Hepatocyte necrosis, inflammatory infiltration |
Differential diagnosis is carried out with other causes of jaundice and liver dysfunction.
Treatment
The therapeutic approach includes a comprehensive impact on all links of pathogenesis. General treatment is aimed at maintaining vital functions of the body. Pharmacological therapy includes the use of hepatoprotectors, antioxidants and detoxifying agents. Surgical treatment is indicated for some forms of acute failure. Alternative methods include plasmapheresis and artificial support of liver function.
List of drugs used to treat this disease
The main groups of drugs used in therapy:
- Hepatoprotectors (ursodeoxycholic acid)
- Antioxidants (vitamin E, glutathione)
- Anti-inflammatory drugs
- Antibiotics for infectious complications
- Drugs for the correction of coagulopathy
Disease monitoring
Patient monitoring includes regular assessment of blood biochemistry every 12-24 hours. The prognosis depends on the severity of the lesion and the timeliness of treatment. The most dangerous complications include hepatic encephalopathy, renal failure, and multiple organ failure.
Age-related features of the disease
In children, liver failure often develops due to congenital metabolic disorders. In adults, toxic and alcoholic forms predominate. In elderly patients, a more severe course is observed due to concomitant diseases and reduced compensatory capabilities of the body.
Questions and Answers
- How to recognize the early signs of liver failure? Initial symptoms include weakness, loss of appetite, nausea and yellowing of the skin.
- Is it possible to completely restore liver function? With timely treatment, partial restoration of function is possible in the case of an acute form.
- How to eat with liver failure? It is necessary to follow a diet with limited protein and fats, excluding alcohol.
Advice from Dr. Oleg Korzhikov
Many patients often ask about disease prevention. I recommend regularly monitoring liver function when taking medications. A common question concerns nutrition - it is important to remember the need for fractional nutrition in small portions. Many are interested in physical activity - moderate exercise is useful, but excessive fatigue should be avoided. I pay special attention to issues of giving up alcohol, as this is the main preventive factor.
