补硒对呼吸道合胞病毒急性下呼吸道感染的效果观察

Effects of Selenium Supplement on Acute Lower Respiratory Tract Infection Caused by Respiratory Syncytial Virus

为评价补硒对呼吸道合胞病毒（ＲＳＶ）所致急性下呼吸道感染的疗效，采用双盲随机对照法，对７５例１岁以下ＲＳＶ感染的肺炎或毛细支气管炎住院患儿进行干预研究。结果表明，补硒组在症状、体征缓解天数方面短于常规治疗组，细胞免疫指标恢复正常者较常规治疗组多。补硒使血浆和白细胞中硒和谷胱甘肽过氧化物酶水平显著增高。

An intervention study was conducted in 75 young children under one year hospitalized with pneumonia or bronchiolitis caused by respiratory syncytial virus (RSV) to evaluate therapeutic effectiveness of selenium (Se) supplement on acute respiratory lower tract infection caused by RSV with randomly controlled and doublemasked method. Trial subjects were divided into two groups, one with 37 children in routine treatment and the other with 38 children in routine treatment plus Se supplement. The control group derived from 35 normal children during their physical checkup in the outpatient department. Sodium selenite was supplemented orally with 1 mg on the second day of hospitalization. Results showed that days needed for their relief of symptoms and signs were fewer in Se supplement group than that in controls and recovery in indicators of cell immune was better in the former than that in the latter. Levels of Se and glutathione peroxidase in plasma and white cells could be increased by Se supplement. It suggests that Se supplement can promote recovery from RSV infection.
