Risk of herpes zoster with IL-17 inhibitor therapy for psoriasis and other inflammatory conditions.
Background: Psoriasis is a chronic inflammatory skin disease that has been associated with a significantly higher risk of herpes zoster (HZ). Several newer biologics such as secukinumab, ixekizumab, and brodalumab inhibit IL-17 and have been highly effective for treatment of psoriasis. However, adverse events related to the immunosuppressive properties of these biologics have been observed. ⋯ Conclusion: IL-17 inhibitors do not appear to increase risk of HZ. However, IL-17 inhibitors are relatively new medications, and further long-term data may be necessary to confirm this finding. Nevertheless, HZ vaccination should be considered on a case-bycase basis prior to initiating IL-17 therapy.
