Abstract

Purpose: Intravitreal aflibercept, ranibizumab, bevacizumab, and dexamethasone are the most widely used drugs in the treatment of diabetic macular edema (DME). The aim of this study was to compare the efficacy and safety of anti-vascular endothelial growth factors and dexamethasone for the treatment of DME. Methods: There were nine previous systematic reviews on this topic; we updated these high-quality reviews. Seven studies were added to two studies following a literature search. Efficacy outcomes were 1) average improvement in visual acuity, 2) proportion of patients who experienced an improvement in vision (an increase in best-corrected visual acuity (BCVA) of ${\geq}15$ in the Early Treatment Diabetic Retinopathy Study [ETDRS]), and 3) proportion of patients who experienced worsening vision (a decrease in BCVA of ${\geq}15$ in the ETDRS). Safety outcomes included systemic adverse events and ocular-related adverse events. Results: The mean difference in the BCVA for ranibizumab versus bevacizumab treatment was 0.16 (95% confidence interval [CI]: -0.02, 0.34), and that for ranibizumab versus aflibercept was -0.08 (95% CI: -0.26, 0.10). The mean difference in the change of BCVA for aflibercept versus ranibizumab was -0.20 (95% CI: -0.40, -0.01), and that for aflibercept versus bevacizumab was -0.34 (95% CI: -0.53, -0.14). Other efficacy outcomes showed similar trends, and there was no significant difference between treatments. There was also no significant difference in both systemic and ocular adverse events rates between the treatments. Conclusions: In DME patients, the efficacy of aflibercept was found to be higher with respect to BCVA changes compared with ranibizumab or bevacizumab. However, there were no significant difference in terms of visual acuity improvement or visual acuity of more than 15 letters, nor in terms of anti-vascular endothelial growth factors (as a safety outcome).

목적: 당뇨황반부종 환자에서 항혈관성장인자의 유리체내주입술의 유효성과 안전성을 알아보고자 하였다. 대상과 방법: 연구목적에 부합하는 최근의 고품질의 체계적인 검토를 선정하였고, 선정된 문헌 고찰에 7건의 최근 수행된 무작위 임상시험을 추가하여 메타분석 및 네트워크 메타분석을 시행하였다. 유효성 결과 지표로는 1) 시력의 평균 향상, 2) 15글자 이상의 최대교정시력 개선을 경험한 환자의 비율, 3) 15글자 이상의 최대교정시력 저하를 경험한 환자의 비율을 파악하였고, 안전성 결과에는 전신이상 반응 및 안구 관련 이상 반응을 분석하였다. 결과: 라니비주맙과 베바시주맙의 교정시력의 평균 차이는 0.16 (95% confidence interval [CI]: -0.02, 0.345)이었고, 라니비주맙 대 애플리버셉트의 평균시력 차이는 -0.08 (95% CI: -0.26, 0.10)이었다. 치료 전후의 시력변화를 약제 간의 비교한 최대교정시력 변화지표에서 라니비주맙(-0.20; 95% CI: -0.40, -0.01)과 베바시주맙(-0.34; 95% CI: -0.53, -0.14)이 각각 애플리버셉트에 비해 효과가 낮은 것으로 나타났다. 전신 및 안구 부작용에서 약제 간에 유의한 차이가 없었다. 결론: 당뇨황반부종에서 애플리버셉트는 라니비주맙 또는 베바시주맙에 비하여 최대교정시력의 변화에 있어서 보다 효과적인 것으로 나타났다. 그러나 15글자 이상의 시력향상이나 시력저하에 있어서는 세 가지 약제에서 유의한 차이를 보이지 않았다. 항혈관성장인자의 안전성은 약제 간에 유의한 차이를 보이지 않았다.
