 近年未熟児網膜症に対しての抗VEGF(vascular endothelial growth factor)療法の有効性が報告され,本邦でも 使用されるようになった。一方で治療により抗VEGF 抗体が全身へ波及し新生児期にVEGF が抑制されるため,児 の発達予後への影響が懸念されているが本邦では報告がない。
 当院で未熟児網膜症に対して抗VEGF 療法を行った早産児の3 歳時身体発育,神経予後について評価した。
 2008 年4 月から2015 年3 月に当院に入院し,未熟児網膜症に対して加療を要した早産児で,新版K 式発達検査 を施行した20 例を対象とした。レーザー治療群12 例と抗VEGF 療法群8 例に分けて,患者背景,入院中合併症, 3 歳時の身体発育,新版K 式検査結果について後方視的に検討した。両群間において,患者背景,入院中合併症に 差はなかった。3 歳時の身長,体重,頭囲のSD スコア,新版K 式検査結果はいずれも有意差を認めなかった(3 歳 時体格SD スコア:身長 -1.4(-4.0 ~ 0.7) vs -0.8(-2.8 ~-0.1),体重 -1.4(-3.1 ~ 1.0) vs -0.9(-3.6 ~ -0.1),頭囲0.1(-4.1 ~ 1.4) vs -0.4(-1.4 ~ 0.2),新版K 式検査結果:全領域DQ 71.5(42 ~ 92) vs 79.5(55 ~ 100),姿勢・運動DQ 61.5(32 ~ 111) vs 76.5(53 ~ 100),認知・適応DQ 77.5(45 ~ 89) vs 82.5(58 ~ 100), 言語・社会DQ 67.0(42 ~ 94) vs 76.5(47 ~ 100))。今回の検討は単施設からの報告であり症例数も少ないため, 今後は多施設による前方視的調査が必要と考えられる。
 The effectiveness of anti-vascular endothelial growth factor( VEGF) agent for retinopathy of prematurity( ROP) was recently reported and is now used in Japan. Plasma VEGF is suppressed by anti-VEGF agent that spreads throughout the body during the neonatal period;therefore, the influence of anti-VEGF agent on the development prognosis must be determined. To date, no study has investigated this issue in Japan.
 The growth and neurodevelopmental outcome at 3 years of age were evaluated in children who were preterm infants treated with an anti-VEGF agent for ROP. Twenty children born as preterm infants between April 2008 and March 2015 who were treated for ROP were followed up and assessed at 3 years of age using the Kyoto Scale of Psychological Development (KSPD). The children’s neonatal characteristics, complications, growth, and KSPD test results were retrospectively analyzed at 3 years of age. The children were classified into 2 groups based on the treatment received:laser group( n=12) and anti-VEGF agent group( n=8).
 There were no significant intergroup differences in neonatal characteristics or complications, nor in standard deviation score( SDS) for body weight, height, head circumference, or KSPD test result at 3 years of age[ physique SDS:height, -1.4( -4.0 to 0.7) vs -0.8( -2.8 to -0.1);weight, -1.4( -3.1 to 1.0) vs -0.9( -3.6 to -0.1);head circumference, 0.1 (-4.1 to 1.4) vs -0.4 (-1.4 to 0.2);KSPD result:Total Developmental Quotient (DQ), 71.5 (42 to 92) vs 79.5 (55 to 100);Postural-Motor DQ, 61.5 (32 to 111) vs 76.5 (53 to 100);Cognitive-Adaptive DQ, 77.5 (45 to 89) vs 82.5 (58 to 100);Language-Social DQ, 67.0( 42 to 94) vs 76.5( 47 to 100)]. This single-center study was limited by its small sample size. Further studies with a multicenter prospective design are needed to verify the results.
