摘要:

目的 比较8个红细胞(RBC)参数运算公式在儿童缺铁性贫血(IDA)与β-地中海贫血(β-TT)鉴别诊断中的效能。方法 选取149例IDA患儿和146例β-TT患儿,对其RBC参数进行检测。选取8种国外常用RBC参数运算公式(F1~F8),对其敏感性(SEN)、特异性(SPE)、阳性预测值(PPV)、阴性预测值(NPV)、约登指数(YI)、阳性似然比(+LR)、阴性似然比(-LR)进行分析。绘制受试者工作特征(ROC)曲线,并计算曲线下面积(AUC)。结果 公式F5、F4和F2的鉴别诊断效能显著高于其他5个公式,这3个公式的AUC分别为0.916、0.889和0.889。公式F5的鉴别诊断效能最高,其SEN、SPE分别为87.14%、88.41%。结论 公式F5、F4和F2对惠州地区儿童IDA与β-TT有较好的鉴别诊断效能,公式F5的鉴别诊断效能最高,可供本地区儿科医生选用。

Abstract:

Objective To evaluate the efficiency of 8 red blood cell(RBC) parameter formulas for the differential diagnosis of iron-deficiency anemia(IDA) and beta-thalassemia trait(β-TT) in children. Methods A total of 149 patients with IDA and 146 patients with β-TT were enrolled. Their RBC parameters were determined. Totally,8 foreign common RBC parameter formulas(F1-F8) were used. Their sensitivities(SEN),specificities(SPE),positive predictive values(PPV),negative predictive values(NPV),Youden indices(YI),positive likelihood ratios(+LR) and negative likelihood ratios(-LR) were evaluated. Receiver operating characteristic(ROC) curves were constructed,and the areas under curves(AUC) were calculated. Results The efficiencies of F5,F4 and F2 for the differential diagnosis of IDA and β-TT were high,and the AUC were 0.916,0.889 and 0.889,respectively,which were higher than those of the other 5 formulas. The efficiency of F5 was the highest,and the SEN and SPE were 87.14% and 88.41%,respectively. Conclusions F5,F4 and F2 show high efficiencies for the differential diagnosis of IDA and β-TT,especially for F5,which can be used for pediatric clinicians in Huizhou.
