From the Medical Board of the National Psoriasis Foundation: Recommendations for screening for hepatitis B infection prior to initiating anti-tumor necrosis factor-alfa inhibitors or other immunosuppressive agents in patients with psoriasis

Background: No consensus exists regarding the optimal laboratory screening for hepatitis B infection that should be performed before initiating therapy with tumor necrosis factor-alfa inhibitors or other immunosuppressive agents. Objective: We sought to give guidelines on which tests to order for hepatitis B screening. Methods: We review the pathophysiology and serology of hepatitis B infection and provide recommendations for screening for hepatitis B infection in patients with psoriasis before beginning anti-tumor necrosis factor-alfa therapy or other immunosuppressive agents. Results: We propose the standardized use of triple serology testing: hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody in combination with liver function tests as screening. Limitations: Conclusions based on review of available literature is a limitation. Conclusions: All patients with psoriasis who are candidates for tumor necrosis factor-alfa inhibitor should undergo screening for hepatitis B virus infection using the triple serology: hepatitis B surface antigen, hepatitis B surface antibody, and hepatitis B core antibody. It is advisable that patients, who are candidates for ustekinumab, cyclosporine, or methotrexate undergo the same screening.
