A total of 75 (45 males, 30 females) patients with sickle cell disease (SCD) at the university of Maiduguri Teaching Hospital were screened for G-6-PD deficiency and their steady state levels of haematocrit, reticulocyte count and irreversibly sickled cells (ISC) as well as the occurrence of vaso-occlusive crises were analysed with respect to their G-6-PD status during a 3 year period (1998-2000). None of the female patients was G-6-PD deficient, while (15.6%) male patients had the enzyme deficiency. The patients with G-6-PD deficiency had significantly lower mean level of haematocrit (0.221/l) with higher level of reticulocyte count (15%) as compared to their non-G-6-PD deficient counter parts who had mean values of 0.271/l and 9% for haematocrit count respectively. However, there was no significant difference in mean levels of ISC between G-6-PD deficient (6%) and non-G-6-PD deficient (5%) patients with SCD. Patients with G-6-PD deficiency had significantly lower episodes of vaso-occlusive crises (2.1 episodes/patient). This data would suggest that co-inheritance of G-6-PD deficiency in SCD reduces frequency of crises and improves prognosis.
在迈杜古里大学教学医院,对75例镰状细胞病(SCD)患者(45例男性,30例女性)进行了葡萄糖-6-磷酸脱氢酶(G-6-PD)缺乏症筛查,并在3年期间(1998 - 2000年),根据他们的G-6-PD状态,分析了他们的血细胞比容、网织红细胞计数和不可逆镰状细胞(ISC)的稳态水平以及血管闭塞性危机的发生情况。女性患者均无G-6-PD缺乏,而男性患者中有(15.6%)存在该酶缺乏。与非G-6-PD缺乏的对应患者相比,G-6-PD缺乏的患者血细胞比容平均水平显著更低(0.221/l),网织红细胞计数水平更高(15%),非G-6-PD缺乏的对应患者血细胞比容计数平均值分别为0.271/l和9%。然而,SCD患者中G-6-PD缺乏者(6%)和非G-6-PD缺乏者(5%)的ISC平均水平无显著差异。G-6-PD缺乏的患者血管闭塞性危机发作次数显著更低(2.1次/患者)。这些数据表明,SCD中G-6-PD缺乏的共同遗传可降低危机发生频率并改善预后。
