Sirolimus shows potential benefits for refractory Crohn's disease (CD) in adults, but adverse effects frequently lead to treatment discontinuation. Further research is needed to optimize its use in managing this chronic inflammatory condition.
Area of Science:
- Gastroenterology
- Immunology
- Pharmacology
Background:
- Inflammatory bowel disease (IBD) management faces challenges with medication-refractory cases.
- Pediatric studies suggest sirolimus efficacy in refractory Crohn's disease (CD).
- Limited data exist on sirolimus use in adult refractory CD patients.
Observation:
- This study retrospectively analyzed clinical outcomes of 4 adult patients with refractory CD treated with sirolimus.
- Patients received sirolimus for a median duration of 524 days.
- Some therapeutic benefits were observed during treatment.
Findings:
- All 4 adult patients discontinued sirolimus therapy.
- Treatment discontinuation was primarily due to adverse effects.
- Observed benefits were outweighed by treatment-derived adverse events.
Implications:
- Sirolimus may offer clinical utility in select adult refractory CD cases.
- Treatment-derived adverse effects may limit the long-term role of sirolimus in CD management.
- Further investigation is warranted to balance efficacy and tolerability for sirolimus in adult IBD treatment.
