B18.0: Chronic viral hepatitis B with delta-agent

B18.09: Chronic viral hepatitis B with delta-agent : other and unspecified phase

Chronic viral hepatitis B with delta-agent is a complex liver disease caused by an extended infection with hepatitis B virus (HBV) and an additional, more detrimental, virus known as hepatitis D or delta virus. The dual infection is persistent and leads to more severe liver damage than hepatitis B alone. The key symptoms, although they may not show in everyone, can include fatigue, nausea, loss of appetite, yellowing of the skin and eyes (also known as jaundice), and abdominal discomfort, specifically in the liver area (Upper right side of the abdomen). Progression of the disease can result in serious liver conditions such as cirrhosis or liver cancer. Transmission of both the B and D viruses typically happens through contact with infected blood or other body fluids. Regular monitoring is necessary due to the chronic nature of the disease and the potential for serious liver complications.
