甲型H1N1流感非干预及应用奥司他韦治疗对照研究

目的研究甲型H1N1流感患者在非干预自然状态下的病情演变过程及预后,并与应用奥司他韦（达菲）治疗患者进行对照研究。方法对93例甲型H1N1流感确诊患者进行前瞻性临床观察,将入院时发病时间〉48h的51例患者纳入不应用奥司他韦治疗的非干预组,将发病时间≤48h者的42例患者纳入奥司他韦组,比较两组患者的临床特征、症状持续时间、病毒转阴时间以及奥司他韦对患者病程的影响。结果两组患者临床表现较季节性流感轻,生化检查基本正常。非干预组发热持续时间为（4.16±3.04）d,病毒核酸转阴时间为（5.79±1.91）d;奥司他韦组发热持续时间为（2.53±1.46）d,病毒核酸转阴时间为（4.91±1.44）d;两组比较有显著性差异。结论甲型H1N1流感患者病情表现较为温和,流感样症状轻,轻症患者可呈自限性经过,可不予奥司他韦治疗,但隔离时间应适当延长至病后7d。
