A Case of Hepatic Tuberculosis in a Patient on Adalimumab for Ankylosing Spondylitis.

Hepatic tuberculosis (TB) is an uncommon extrapulmonary manifestation of tuberculosis. Hepatic TB is more common in immunocompromised patients, such as those on immunosuppressive medications or those with a human immunodeficiency virus (HIV) infection. Primary hepatic TB is rare, and liver involvement is often secondary to spreading from the lymphatics, portal vein, or hepatic artery. We report a case of hepatic TB in a patient on adalimumab for ankylosing spondylitis (AS).

Polyarteritis Nodosa Associated With Hepatitis C Virus Infection.

Polyarteritis nodosa (PAN) is a rare necrotizing vasculitis that affects medium-sized arteries. The association of hepatitis B virus (HBV)and HIV with PAN is well documented. Although there are documented cases of PAN in patients with hepatitis C virus (HCV) infection, the connection between PAN and HCV is not well established. We report a case of PAN in a patient with HCV infection who failed treatment with interferon.
