170例儿童继发性血小板增多症发病情况分析

目的分析儿童继发性血小板增多症(ST)的发病率及临床病因分布,以期指导临床治疗。方法对江苏省高邮市中医医院及常州市儿童医院170例确诊为ST患儿的临床资料进行回顾分析,探讨其病因分布、总发病率和不同年龄段的发病情况。结果 ST原发性病因主要包括感染性疾病(尤以呼吸道为主)、贫血、免疫性疾病、药物、外科疾病等,新生儿疾病引起的血小板增多亦常见。ST在儿童中发病率为3.37%,在新生儿、婴幼儿、3岁及以上儿童中发病率分别为2.48%、3.78%、1.99%,差异有统计学意义(P0.05)。结论 ST是儿童较常见的并发症,尤其见于3岁以下儿童,引起该病的病因繁多,最主要是呼吸道和消化道感染;其中3岁以下儿童,特别是呼吸道感染的婴幼儿更易并发血小板增多。

Objective To analyze the morbidity rate and clinical etiology distribution of secondary thrombocytosis(ST ) in chil‐dren in order to guide the clinical treatment .Methods The clinical data of 170 children patients with ST in hospitals were retro‐spectively analyzed for investigating its etiology distribution ,total morbidity and onset situation in different age periods .
