Inflammatory bowel disease new-onset during secukinumab therapy: real-world data from a tertiary center.

Secukinumab is a monoclonal antibody that inhibits interleukin-17A. It is currently prescribed for the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis, which are immune-mediated diseases that show significant co-heritability with inflammatory bowel disease (IBD). Although this treatment appears to be well tolerated by patients, several cases of new-onset IBD after secukinumab have been reported during the last years.
