B16.0

Clinical Causes: Transmission of hepatitis B virus through exposure to infected blood, sexual contact, or from mother to child during childbirth. Co-infection with hepatitis delta virus, which requires an existing hepatitis B infection to replicate. High-risk behaviors such as unprotected sex, sharing needles, or exposure to contaminated blood products. Poor sanitation and hygiene practices that facilitate virus spread.

Key Symptoms: Jaundice (yellowing of the skin and eyes) Fatigue and weakness Loss of appetite Nausea and vomiting Abdominal pain or discomfort, particularly in the upper right side Dark urine and pale stool Fever Muscle or joint pain In more severe cases, signs of hepatic coma such as confusion, drowsiness, or unresponsiveness

Diagnosis Path: Diagnosis is conducted through a combination of blood tests, imaging, and clinical evaluation. Key steps include: - Blood tests to detect hepatitis B surface antigen (HBsAg), hepatitis delta antibodies, liver enzymes, and bilirubin levels. - Liver function tests to assess degree of liver impairment. - Imaging studies like ultrasound to evaluate liver damage. - In some cases, a liver biopsy might be recommended to determine the extent of liver injury. - Assessment of neurological status to identify hepatic coma symptoms.

Treatment Protocols: Managing this condition involves supportive care and addressing the underlying causes: - Hospitalization may be necessary for severe cases, especially with hepatic coma. - Medications such as antiviral agents (like tenofovir or entecavir) to control hepatitis B. - Monitoring and managing complications like bleeding, fluid buildup, or infections. - Nutritional support to maintain strength. - Avoidance of alcohol and hepatotoxic medications. - In cases of hepatic coma, intensive supportive care, including airway management and measures to reduce brain swelling. - Long-term management may involve vaccination to prevent hepatitis B and additional antiviral therapy.
