摘要
目的观察病毒性下呼吸道感染患儿血小板的变化。方法回顾性研究2005年6月至2007年6月温州医学院育英儿童医院收治的420例下呼吸道合胞病毒(RSV)、流感病毒、副流感病毒及腺病毒感染患儿的血小板变化。血小板增多以>400×109/L为标准。结果RSV感染患儿血小板计数明显高于其他病毒感染,在91例血小板增多患儿中,RSV感染占67例(73.6%),227例RSV感染患儿血小板增多发生率为29.5%(67/227)。与其他病毒感染比较,RSV下呼吸道感染患儿的年龄小、血红蛋白低及呼吸窘迫发生率高。结论下呼吸道病毒感染时,血小板增多易发生于RSV感染者,血小板增多可作为下呼吸道RSV感染早期实验室指标。
Objective Secondary thrombocytosis is associated with a variety of clinical conditions.The aim of this study is to determine whether thrombocytosis occurs at an early stage of lower respiratory tract viral infection.Methods The medical records of 420 patients with respiratory syncytial virus（RSV）,influenza,parainfluenza and adenovirus infections were retrospectively reviewed.We have defined thrombocytosis as platelet count above 400×10^9/L.Results The mean platelet count was significantly higher in RSV patients than in patients with other respiratory infections.Among the 91 patients with thrombocytosis,67（73.6%）had RSV infection.Sixty-seven out of 227 RSV patients（29.5%）exhibited thrombocytosis.Compared with patients with other respiratory infections,the mean age and concentration of hemoglobin were significantly lower and the presence of respiratory distress was more prominent in RSV patients.Conclusion When thrombocytosis is positive at an early stage of lower respiratory tract viral infection,RSV should be taken into account as a causative agent.
