摘要
目的分析儿童缺铁性贫血(iron deficiency anemia,IDA)的病因、临床和实验室特点。方法对114例儿童IDA的病因、临床表现和实验室资料进行分析。结果IDA中婴幼儿占76.31%,农村儿童58.77%,城市儿童41.23%。母乳喂养但未按时添加辅食者64.04%,人工喂养(配方奶粉)、混合喂养者分别占14.91%和21.05%。多数患儿有面色苍白、肝脾轻度肿大、骨髓有核红细胞增生活跃,外周血检查显示小细胞低色素贫血、血清铁、运铁蛋白饱和度异常率分别为95.37%和100%。合并感染者63.83%。结论IDA好发于婴幼儿,农村儿童较城市儿童多见,母乳喂养但未按时添加辅食者较人工喂养、混合喂养者患病率高。IDA婴幼儿髓外造血多见,合并感染者多见且贫血程度较重。血清铁、运铁蛋白饱和度降低是诊断IDA最可靠的指标。
Objective Eitology and clinical features in iron deficiency anemia （IDA） were investigated. Methods To analyze the clinical data in 114 inpatients of IDA from January 2000 to March 2006. Results The prevalence rate of IDA was highest in infants（76. 31% ）. IDA in countryside was 58. 77% which was more prevalent than that in city （41.23%）. The prevalence rate of IDA was 64.04% in infants with breast-feeding without supplement on time which was higher tian that in infants with artificial feeding（ 14. 91% ） and mixed feeding（21.05% ）, and also the former presented severe degree of anemia （P〈0. 05 ）. Most patients presented with pallor, mild hepatosplenomegaly and nucleated red cell hyperptasia in BM, Abnormal rates of SI and TS were 95.37% and 100% respectively. Inpatients of IDA with concurrent infection accounted for 63.83%. Conclusions IDA was more prevalent in infants and children living in countryside. Infants with breast-feeding without supplement were at higher risk for IDA. Extramedullary hematopoiesis was common in infants with IDA. Patients with concurrent infections showed severe degree of anemia. For iron metabolism, SI and TS are most reliable index for helping diagosis of IDA.
