Management of hepatitis D in general practice.

BACKGROUND

Hepatitis D virus (HDV) requires the presence of hepatitis B virus for replication and infection, and is associated with accelerated progression to cirrhosis and an increased risk of hepatocellular carcinoma. Approximately 4% of Australians living with hepatitis B are infected with HDV, although it is likely that HDV remains underdiagnosed.

OBJECTIVE

This paper highlights the importance of screening for HDV in patients living with chronic hepatitis B (CHB) and provides an overview of diagnosis and treatment approaches for general practitioners (GPs), with the hope of reducing preventable liver-related morbidity and mortality in people living with CHB and HDV coinfection.

DISCUSSION: The diversity of risk factors and geographical origins of patients in the multicultural Australian populace highlights the need for routine testing for HDV in patients diagnosed with CHB. GPs have a pivotal role in the diagnosis of HDV and should, if possible, promptly refer patients to non-GP specialist physicians to consider HDV therapy.
