摘要:

目的 探讨毛细管电泳分析仪在诊断血红蛋白(Hb)CS-H病中的应用价值。方法 用SebiaCapillarys2型毛细管电泳仪分别对经地中海贫血基因分析确诊的34例HbCS-H病患者和70例非HbCS-H病患者(包括42例-SEA/-α3.7、19例-SEA/-α4.2、7例HbWS-H、2例HbQS-H)进行Hb电泳。采用缺口聚合酶链反应(Gap-PCR)和反向斑点杂交的方法对2组患者进行地中海贫血基因分析。结果 毛细管电泳分析HbCS-H组的HbCS带含量为(1.89±1.33)%,HbH带含量为(1.07±0.86)%,HbA2带含量为(1.17±0.68)%;非HbCS-H组均未能检测到HbCS带,有部分标本未检出HbH带,HbA2带含量为(1.81±1.21)%。2组HbA2带含量比较差异有统计学意义(P<0.05)。毛细管电泳仪诊断HbCS-H病的敏感性和特异性分别为88.2%和100.0%,阳性预测值为100.0%,阴性预测值为94.6%,诊断效率为96.2%,与地中海贫血基因分析比较差异无统计学意义(P=0.134)。结论 毛细管电泳可以用来快速诊断HbCS-H病,能够为患者减轻部分经济负担。

Abstract:

Objective To investigate the application significance of capillary electrophoresis analyzer in the diagnosis of hemoglobin(Hb) CS-H disease. Methods A total of 34 patients with Hb CS-H disease confirmed by thalassemia genetic analysis and 70 patients with non Hb CS-H disease (including 42 cases of -SEA/-α3.7,19 cases of -SEA/-α4.2,7 cases of Hb WS-H and 2 cases of Hb QS-H) were determined for Hb with Sebia Capillarys 2 capillary electrophoresis. The thalassemia genetic analysis of the 2 groups was conducted bygap-polymerase chain reaction (Gap-PCR) and reverse dot blot hybridization. Results The HbCS and HbH contents of Hb CS-H group were (1.89±1.33)% and (1.07±0.86)%,and the HbA2 content was (1.17±0.68)%. However,the samples with HbCS and a part of HbH were not detected in non-Hb CS-H group,and the HbA2 content was (1.81±1.21)%. Compared with Hb CS-H group and non-Hb CS-H group for HbA2,there were significant significance (P<0.05). Compared with the thalassemia genetic analysis,the sensitivity of capillary electrophoresis for the diagnosis of Hb CS-H disease was 88.2%,the specificity was 100.0%,the positive predictive value was 100.0%,the negative predictive value was 94.6%,the diagnosis efficiency was 96.2%,and there was no statistical significance (P=0.134). Conclusions The capillary electrophoresis can be used to the rapid diagnosis of Hb CS-H disease,and it will alleviate some of the economic burdens for patients.
