Jaundice

Jaundice is a clinical syndrome characterized by yellowing of the skin, mucous membranes, and sclera of the eyes, resulting from elevated levels of bilirubin in the blood. The pathological process associated with impaired bilirubin metabolism may be caused by various diseases of the liver, biliary tract, and systemic disorders. Jaundice may be both an independent condition and a symptom of more serious diseases, such as hepatitis, cholelithiasis, or pancreatitis. The ability to differentiate the type of jaundice (hepatic jaundice, subcutaneous jaundice, or confluent jaundice) is extremely important for establishing the correct diagnosis and prescribing appropriate treatment.

History of the disease and interesting historical facts

Jaundice has been known to mankind since ancient times. Parallel evidence of its manifestations can be found in medical texts of various cultures. For example, ancient Egyptian papyri already described symptoms similar to jaundice, and Hippocrates mentioned the yellowish color of the skin. In the Middle Ages, there were various myths associated with jaundice manifestations, including the belief that this condition is a consequence of evil spirits or damage to the body by evil spirits. At the beginning of the 20th century, scientific research began to actively develop, which allowed a deeper understanding of the etiology and pathogenesis of jaundice. Establishing a link between jaundice and liver diseases became possible thanks to discoveries in the field of biochemistry and histology.

Epidemiology

Today, jaundice is an important medical and social problem. According to the World Health Organization, jaundice of various types is observed in almost 20% of the population during their lifetime. Acute viral hepatitis and other liver diseases continue to occupy leading positions in morbidity. In some regions where there is a high prevalence of hepatitis B and C, the rate of jaundice can exceed 50 cases per 100,000 population. In countries with developed health care systems, such as Europe and North America, the rate of jaundice is lower, but the problem of identifying and treating chronic liver diseases that can lead to jaundice as a result of progression remains relevant.

Genetic predisposition to this disease

Genetic predisposition plays a significant role in the development of jaundice, especially in cases associated with hereditary diseases. One of the most common genetic disorders is Gilbert's syndrome, which is associated with a deficiency of the enzyme uridine diphosphoglucuronosyltransferase (UGT1A1). Also of importance is the gene ATP-binding cassette sub-family C member 2 (ABCC2), which is involved in the removal of bilirubin from liver cells. Other important genes involved in bilirubin metabolism include UGT1A1 and UGT1A6. Mutations in these genes can lead to various forms of hereditary jaundice and elevated bilirubin levels.

Risk factors for the development of this disease

The development of jaundice can be caused by many factors, which can be divided into physical and chemical. The main risk factors include:

• Viral infections (hepatitis A, B, C, D, E);
• Alcoholism and drug abuse;
• Poor nutrition and sedentary lifestyle;
• Age and gender (men are at greater risk);
• The presence of chronic diseases of the digestive system;
• Environmental pollution and exposure to toxic substances.

These factors can either directly lead to liver disease or contribute to the worsening of existing diseases, which ultimately leads to the development of jaundice.

Diagnosis of this disease

The main symptoms of jaundice include yellowing of the skin and mucous membranes, darkening of urine and discoloration of stool, and itching. To confirm the diagnosis and determine its etiology, various laboratory tests are carried out, such as:

• Blood test for bilirubin levels (total, free and conjugated);
• Determination of transaminase activity (ALT, AST);
• Diagnostics of viral hepatitis (viral markers);
• Complete blood count to check for anemia or leukopenia.

Radiological examinations such as abdominal ultrasound provide visualization of changes in the liver and biliary tract. Other diagnostic methods may include liver biopsy to clarify the pathology. It is also important to perform a differential diagnosis by excluding other causes of jaundice such as any form of hemolysis or metabolic disorders.

Treatment

General treatment of jaundice depends on its cause. In cases caused by viral infections, antiviral drugs are prescribed for specific therapy. Pharmacological treatment includes hepatoprotectors, which improve liver function. Surgical intervention may be necessary for mechanical jaundice caused by gallstones or tumors that obstruct the outflow of bile. In addition, in some cases, the use of immunosuppressants is indicated, especially in autoimmune liver damage. It is also necessary to pay attention to the diet: limiting the consumption of fatty and fried foods, alcohol, and maintaining a balanced diet are important aspects in the treatment of jaundice.

List of medications used to treat this disease

Among the drugs recommended for the treatment of jaundice, the following can be distinguished:

• Ursodeoxycholic acid
• Silymarin (milk thistle extract);
• Phospholipids (Essentiale, Phosphon-cir);
• Antiviral drugs (ribavirin, sofosbuvir);
• Corticosteroids (prednisolone) for autoimmune diseases.

The list of medications may vary depending on the type of jaundice and its etiology, so it is important to follow your doctor's instructions.

Disease monitoring

Monitoring jaundice involves regular checkups to monitor bilirubin levels and other liver enzymes. The prognosis depends on the etiology of jaundice and the timeliness of diagnosis. Complications may include cirrhosis, liver failure, or liver cancer if not treated appropriately. Therefore, it is important for patients to follow their doctor’s recommendations and have regular checkups.

Age-related features of the disease

Jaundice can manifest itself differently depending on the patient's age. In newborns, physiological jaundice is often observed in the first days of life and is treated without special interventions. In children and adolescents, jaundice can be associated with viral infections or toxic effects. In adults, jaundice associated with chronic liver diseases, most often caused by alcoholism or viral hepatitis, is more pronounced. In the elderly, jaundice can be associated with more serious comorbid conditions, which complicates its diagnosis and treatment.
