What is the risk of tuberculosis (TB) during biologic treatment with agents other than tumor necrosis factor (TNF)-alpha inhibitors?
Gülen Hatemi, MD: Interleukin (IL)-1 blockers are considered to be safe regarding the development of TB. But we actually have 2 patients who developed TB while using an anti–IL-1 blocker. IL-17 blockers really seem to be safe. There are data from psoriasis and psoriatic arthritis trials. As far as I remember, there were more than 2000 patients and none of them developed TB. With IL-6 blockers there can also be some risk of TB.
