Secukinumab, an anti-interleukin-17 therapy, may trigger new-onset inflammatory bowel disease (IBD) in susceptible individuals. Physicians should assess IBD and multiple sclerosis (MS) risk factors before prescribing anti-IL-17 agents.
Area of Science:
- Immunology
- Gastroenterology
- Rheumatology
Background:
- Secukinumab targets interleukin-17 (IL-17), a cytokine implicated in autoimmune diseases.
- Elevated IL-17A levels are observed in inflammatory bowel disease (IBD), yet IL-17 inhibition may worsen IBD activity.
- Multiple sclerosis (MS) shares suspected associations with IBD.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
