Anti-TNF-A Therapy about Infliximab and Adalimamab for the Effectiveness in Ulcerative Colitis Compared with Conventional Therapy: A Meta-Analysis.

Background/aims: TNF-α has an important role in the pathogenesis of ulcerative colitis (UC). It seems that anti-TNF-α therapy is beneficial in the treatment of UC. The aim was to assess the effectiveness of Infliximab and Adalimamab with UC compared with con- ventional therapy.
Methodology: The Pubmed and Embase databases were searched for studies investigating the efficacy of infliximab and adalimumab on UC.
Results: Infliximab had a statistically significant effects in induction of clinical response (RR = 1.67; 95% CI 1.12 to 2.50) of UC compared with conventional therapy, but those had not a statistically significant effects in clinical remission (RR = 1.63; 95% CI 0.84 to 3.18) and reduction of colectomy rate (RR = 0.54; 95% CI 0.26 to 1.12) of UC. And adalimumab had a statistically significant effects in induction of clinical remission (RR =1.82; 95% CI 1.24 to 2.67) and clinical response (RR =1.36; 95% CI 1.13 to 1.64) of UC compared with conventional therapy.
Conclusion: Our meta-analyses suggested that Infliximab had a statistically significant effects in induction of clinical response of UC compared with conventional therapy and adalimumab had a statistically significant effects in induction of clinical remission and clinical response of UC compared with conventional therapy.
