轻型地中海贫血孕妇妊娠晚期贫血的其他相关因素探讨

目的探讨轻型地中海贫血孕妇妊娠晚期贫血的其他相关因素,揭示妊娠期铁(Fe)、维生素B12(Vit B12)、叶酸(Fol)的代谢状况,旨在为临床提高轻型地中海贫血孕妇血红蛋白水平提供理论依据。方法选取在我院定期产检的孕28～40周孕妇84例,α地贫23例(A组)、β地贫21例(B组)、100g/L<血红蛋白(HGB)<110g/L 19例(C组)、HGB≥110g/L 21例(D组)。所有病例检测血红蛋白(HGB)、血清铁蛋白(SF)、血清维生素B12(Vit B12)、血清叶酸(Fol),同时对各项指标进行统计分析。结果①A组HGB较B组高(P<0.05),A组发生贫血风险是B组的0.285倍。②SF比较:除A组低于D组(P<0.05)、B组高于C组(P<0.05)、C组低于D组(P<0.05)外,其余各组间比较P>0.05。Fol、Vit B12在四组间比较P>0.05。③储铁缺乏率:A组高于D组(P=0.0048);C组高于D组(P=0.0016);储铁减少率四组间比较P>0.05。④储铁缺乏风险:A组是D组的3.196倍(P<0.05);C组是D组的3.592倍(P<0.05)。储铁减少风险:B组是C组的0.704倍(P<0.05);C组是D组的1.530倍(P<0.05)。结论①轻型地贫并不增加晚期妊娠孕妇铁负荷,与正常孕妇一样可出现铁缺乏;②β地贫低HGB水平较α地贫多,提示β地贫孕妇更应该密切动态关注HGB水平,分析贫血的其他相关因素;③α地贫孕妇缺铁风险较非贫血的正常孕妇高,应高度重视合理的铁补充;④地贫孕妇出现HGB降低,且存在SF低时,在实验室的监测下补铁是安全的;⑤HGB 100～110 g/L时,即是缺铁的高危界限,此时及时补铁,可防止HGB进行性降低致妊娠期贫血;⑥Vit B12、Fol与晚期妊娠轻型地贫贫血无明显相关性。

Other anemia related factors of thalassemia minor during the third trimester of pregnancy

Objectives: Discuss other anemia related factors whether to affect thalassemia minor during the third trimester and show the metabolic conditions of iron(Fe),vitamin B12(Vit B12),folic acid(Fol),which is on the purpose of providing the theoretical evidence for correcting low hemoglobin of thalassemia minor during pregnancy.Methods: 84 gravidas(in 28~40 week of pregnancy) enrolled in were all receiving normal antenatal care from the Second Hospital of Guangdong Province,and were divided into four groups: Gro...
