Hepatitis B status uncertain. Four potential interpretations:
1. Recovery from infection
2. False-positive anti-HBc, vulnerable to disease
3. Chronic infection with low disease severity
4. Resolution of acute infection
Key Points
TNF inhibitors have been associated with reactivation of hepatitis B.
First-line treatment for patients with psoriasis and hepatitis B is topical agents, phototherapy, ustekinumab, secukinumab, and ixekizumab. TNF inhibitors are considered second-line therapy. Avoid methotrexate and acitretin.
Screen patients with psoriasis for hepatitis B prior to TNF inhibitor therapy by analysis of the triple serology: HBsAg, HBsAb, and HBcAb.
