【摘要】:目的引入核酸檢測后,重新評估ALT對血液安全的功效,為優(yōu)化血液篩查策略提供依據(jù)。方法對2010年11月-2015年12月近5年時間北京市紅十字血液中心1 495 863例無償獻血者進行ALT與乙肝標志物(HBs Ag、HBV-DNA)、丙肝標志物(抗-HCV、HCV-RNA)檢測結果分析,評估ALT在肝炎方面對于血液安全的功效。結果 1)ALT不合格獻血者的乙肝檢出率(5.950‰)略高于ALT正常獻血者(3.720‰),ALT不合格獻血者的丙肝檢出率(1.386‰)略低于ALT正常獻血者(4.428‰),差異有統(tǒng)計學意義(χ2值分別為10.60、156.04,P0.01)。2)ALT不合格獻血者的HBV-DNA單陽性檢出率、HCV-RNA單陽性檢出率與ALT正常獻血者均無顯著差異(χ2值分別為0.017、0.086,P0.01)。3)使用百分位數(shù)法計算3 642例獻血者ALT95%界限為59 U/L。4)采用不同ALT判定界值(40 U/L、50 U/L、59 U/L),692例HBV-DNA單陽性獻血者檢出率無統(tǒng)計學差異(χ2=4.502,P0.01)、16例HCV-RNA單陽性獻血者均不能檢出。5)ALT判定界值從40 U/L調整為50 U/L時,平均每年增加2.19%血液資源;如ALT判定界值從50 U/L提升至59 U/L,至少可節(jié)約74.11%單純因ALT不合格的血液。結論開展核酸檢測以來顯著提升了血液安全,ALT對降低輸血傳播風險的功效已極其有限,研究支持取消ALT檢測。在目前政策下,可適當將ALT判定界值調整為59 U/L,在確保血液安全的前提下獲得更多的資源。
