Insights
Early biologic therapy reduces surgery rates in Crohn's disease (CD) but increases colectomy risk in ulcerative colitis (UC). This systematic review analyzes long-term IBD surgery outcomes based on treatment timing.
Area of Science:
- Gastroenterology
- Immunology
- Clinical Medicine
Background:
- Inflammatory bowel disease (IBD) encompasses Crohn's disease (CD) and ulcerative colitis (UC), often leading to significant long-term complications.
- Early biologic treatment in IBD has shown mixed results for short-term outcomes, with conflicting data on long-term adverse events like surgery.
- This study systematically reviews the impact of early versus late biologic intervention on IBD-related surgical rates.
Approach:
- A comprehensive systematic search was performed in April 2022.
- Included studies compared early (<3 years from diagnosis) versus late (>3 years from diagnosis) biologic initiation.
- Meta-analysis of 18 studies assessed colectomy rates in UC and CD-related surgery in CD, excluding studies with <1 year follow-up.
Key Points:
- In Crohn's disease (CD), early biologic therapy was associated with significantly lower odds of surgery (OR 0.63).
- Conversely, in ulcerative colitis (UC), early biologic therapy was linked to increased odds of colectomy (OR 2.86).
- These findings highlight a differential impact of early biologic intervention on surgical outcomes in distinct IBD types.
Conclusions:
- Early biologic treatment demonstrates a protective effect against surgery in Crohn's disease patients.
- However, early biologic therapy may be associated with a higher risk of colectomy in ulcerative colitis patients.
- Disease severity might confound the observed association between early biologics and colectomy in UC.
Background And Aims:
Inflammatory bowel disease (IBD) can lead to long-term complications that significantly impact patients' quality of life and healthcare resource utilization. Prior studies have demonstrated improved short-term outcomes to early exposure of biologics in patients with Crohn's disease (CD) but not in patients with ulcerative colitis (UC). However, there are conflicting data on impact of early intervention on longer-term adverse events. Therefore, we conducted a systematic review and meta-analysis assessing the impact of early biologic treatment on rates of IBD-related surgery.
Methods:
A systematic search was conducted in April 2022. Studies were included if biologic initiation was compared between patients starting early (<3 years of diagnosis or top-down treatment) vs later (>3 years of diagnosis or step-up treatment). Studies with <1 year of follow-up were excluded. The outcomes were colectomy and CD-related surgery for patients with UC and CD, respectively. Random-effects analyses were conducted to compare rates of IBD surgery between early and late biologic treatment.
Results:
Eighteen studies were included in the meta-analysis. Three studies included patients with UC and 15 studies included patients with CD. In patients with CD, early biologic therapy was associated with lower odds of surgery (odds ratio, 0.63; 95% confidence interval, 0.48-0.84) compared with late treatment. Conversely, in patients with UC, the odds of colectomy were increased (odds ratio, 2.86; 95% confidence interval, 1.30-6.30).
Conclusions:
Early biologic treatment is associated with lower rates of surgery in patients with CD. In contrast, early biologic therapy appears to be associated with higher rates of colectomy in patients with UC, which may be confounded by disease severity.
