Objectives: This study is the first meta-analysis to evaluate the efficacy and safety of monoclonal anti-TNF antibodies in patients with vascular Behçet's syndrome (VBS).
Methods: A comprehensive literature search was conducted on PubMed, Embase, Cochrane Library, Medline Complete, and Web of Science. Pooled estimates of clinical response including complete response (CR) and partial response (PR), were calculated at 3, 6, and 12 months. Subgroup analyses were performed based on the specific monoclonal anti-TNF antibodies used. Additionally, pooled proportions of imaging response before and after 6 months were assessed.
Results: Twelve studies involving 297 patients were included. The pooled proportions of clinical CR were 64.1 % (95 %CI 28.7-93.9 %), 89.1 % (95 %CI 72.4-98.6 %), and 94.5 % (95 %CI 82.5-99.8 %) at 3, 6, and 12 months, respectively. Imaging response was achieved in 92.9 % (95 %CI 77.2-100 %) of patients within 6 months and 92.5 % (95 %CI 74.8-99.9 %) after 6 months. During follow-up, 26 patients experienced a relapse while on monoclonal anti-TNF antibodies treatment. Of the 43 patients who discontinued therapy due to response, 28 % (n = 12) experienced a relapse. Adverse events (AEs) were reported in 10 studies involving 42 patients, with 31 patients experiencing severe AEs, including 5 deaths.
Conclusions: Monoclonal anti-TNF antibodies are an effective treatment for VBS, demonstrating significant clinical and radiological efficacy with a favorable safety profile. Prevention of relapses and control of disease progression remain critical objectives in VBS management. Further validation of their efficacy through randomized controlled trials (RCTs) stratified by arterial and venous involvement is warranted to strengthen the evidence base and optimize therapeutic strategies.
