B15.0

Clinical Causes: Infection with hepatitis A virus (HAV) Poor sanitation and contaminated food or water sources Close contact with an infected person Travelers to regions with high hepatitis A prevalence Poor hygiene practices Age-related vulnerability, especially in older adults or those with pre-existing liver conditions

Key Symptoms: Jaundice (yellowing of the skin and eyes) Fatigue and weakness Nausea and vomiting Abdominal pain or discomfort Dark urine and pale stools Fever Loss of appetite Confusion or changes in mental state Lethargy In advanced stages, loss of consciousness or coma

Diagnosis Path: Diagnosing hepatitis A with hepatic coma involves a combination of clinical evaluation and laboratory tests. Blood tests are crucial for confirming hepatitis A infection by detecting specific antibodies (IgM anti-HAV), along with liver function tests (ALT, AST, bilirubin) to assess the extent of liver damage. When hepatic coma occurs, neurological assessments and blood ammonia levels help evaluate brain involvement. Imaging studies like ultrasound may be performed to rule out other causes of liver disease or neurological status. In some cases, further tests such as MRI or CT scans might be necessary to exclude other neurological issues.

Treatment Protocols: Treatment focuses on supportive care to manage symptoms and prevent complications. Hospitalization may be required for close monitoring of liver function and neurological status. Key components include: - Rest and hydration: Maintaining adequate fluid intake - Nutritional support: Nutrient-rich diets tailored to liver health - Monitoring and managing complications such as bleeding or infections - Brain function management: Ensuring proper oxygenation and controlling increased intracranial pressure if present - Avoiding hepatotoxic substances, including alcohol and certain medications - In severe cases, advanced medical interventions may be necessary, including intensive care and potentially liver support therapies. Vaccination against hepatitis A is a preventive measure that significantly reduces the risk of infection, especially for travelers and at-risk populations. Early medical attention is vital to improve outcomes and prevent irreversible liver damage or death.
