主な方法:
- 2022年11月から2023年12月まで,ブカブの15のプライマリヘルスケア施設で前向きなコホート試験が行われました.
- 母親は産前診療所や産婦人科でSCD検査を行い,母親と新生児の血液サンプルを採取した.
- HemoTypeSCTMの点検試験が用いられ,Gazelle®電泳により陽性結果が確認された.
主要な成果:
- 4,496人の母親のうち,70.77%が同意し,8.16%がHbAS特性を,0.22%がHbSS特性を有していた.
- HbSを患った77人の母親の出産までのフォローアップが達成されました.
- 77人の新生児のうち,3. 90%がHbSS (シクル細胞病) と診断されました.
結論:
- 新生児のSCDスクリーニングをブカブの初等保健医療に統合することは可能であり,乳児の早期診断に有効です.
