Background To investigate the efficacy and safety of aerosol inhalation of recombinant human interferon α1b (IFNα1b) injection for noninfluenza viral pneumonia. Methods One hundred sixty-four patients with noninfluenza viral pneumonia were divided into IFNα1b and control groups. The IFNα1b group received routine treatment + aerosol inhalation of recombinant human IFNα1b injection (50 μg × 2 injections, bid). The control group received routine treatment + IFN analog (two injections, bid). Overall response rate (ORR) of five kinds clinical symptoms. Further outcomes were daily average score and the response rate of each of the symptoms above. Results A total of 163 patients were included in the full analysis set (FAS) and 151 patients were included in the per-protocol set (PPS). After 7 days of treatment, ORR of clinical symptoms was higher in IFNα1b group than that in control group for both the FAS and PPS. Moreover, after 7 days of treatment, the daily score of three efficacy indexes including expectoration, respiratory rate, and pulmonary rales were improved. The ORRs for expectoration and pulmonary rales were higher in the IFNα1b group than in the control group (P < 0.05). There were no significant differences of the ORRs for coughing, chest pain and respiratory rate between the two groups (P > 0.05). The incidence of adverse events was 6.5% (n = 5) in IFNα1b group and 3.5% (n = 3) in control group (P > 0.05). Conclusion Aerosol inhalation of recombinant human IFNα1b is safe and it can improve the clinical symptoms of noninfluenza viral pneumonia.

气溶胶吸入重组人干扰素α1b (IFNα1b) 注射液治疗非流感病毒性肺炎的疗效和安全性,一项多中心、随机、双盲、安慰剂对照试验。

背景 研究气雾吸入重组人干扰素α1b(IFNα1b)注射液治疗非流感病毒性肺炎的疗效和安全性。方法将164例非流感病毒性肺炎患者分为IFNα1b组和对照组。干扰素α1b组接受常规治疗+重组人干扰素α1b注射液雾化吸入(50μg×2次注射,bid)。对照组接受常规治疗+干扰素类似物(两次注射,bid)。五种临床症状的总体反应率(ORR)。进一步的结果是每日平均得分和上述每种症状的反应率。结果共有163例患者被纳入全分析集(FAS),151例患者被纳入符合方案集(PPS)。经过7天的治疗,对于 FAS 和 PPS,IFNα1b 组的临床症状 ORR 均高于对照组。而且,治疗7天后,咳痰、呼吸频率、肺部啰音3项疗效指标的每日评分均有改善。IFNα1b 组咳痰和肺部啰音的 ORR 高于对照组(P < 0.05)。两组咳嗽、胸痛、呼吸频率的ORR比较差异无统计学意义(P>0.05)。IFNα1b组不良事件发生率为6.5%(n=5),对照组为3.5%(n=3)(P>0.05)。结论 重组人IFNα1b气雾吸入安全,可改善非流感病毒性肺炎的临床症状。治疗7天后,咳痰、呼吸频率、肺部啰音3项疗效指标的每日评分均有所改善。IFNα1b 组咳痰和肺部啰音的 ORR 高于对照组(P < 0.05)。两组咳嗽、胸痛、呼吸频率的ORR比较差异无统计学意义(P>0.05)。IFNα1b组不良事件发生率为6.5%(n=5),对照组为3.5%(n=3)(P>0.05)。结论 重组人IFNα1b气雾吸入安全,可改善非流感病毒性肺炎的临床症状。治疗7天后,咳痰、呼吸频率、肺部啰音3项疗效指标的每日评分均有所改善。IFNα1b 组咳痰和肺部啰音的 ORR 高于对照组(P < 0.05)。两组咳嗽、胸痛、呼吸频率的ORR比较差异无统计学意义(P>0.05)。IFNα1b组不良事件发生率为6.5%(n=5),对照组为3.5%(n=3)(P>0.05)。结论 重组人IFNα1b气雾吸入安全,可改善非流感病毒性肺炎的临床症状。IFNα1b 组咳痰和肺部啰音的 ORR 高于对照组(P < 0.05)。两组咳嗽、胸痛、呼吸频率的ORR比较差异无统计学意义(P>0.05)。IFNα1b组不良事件发生率为6.5%(n=5),对照组为3.5%(n=3)(P>0.05)。结论 重组人IFNα1b气雾吸入安全,可改善非流感病毒性肺炎的临床症状。IFNα1b 组咳痰和肺部啰音的 ORR 高于对照组(P < 0.05)。两组咳嗽、胸痛、呼吸频率的ORR比较差异无统计学意义(P>0.05)。IFNα1b组不良事件发生率为6.5%(n=5),对照组为3.5%(n=3)(P>0.05)。结论 重组人IFNα1b气雾吸入安全,可改善非流感病毒性肺炎的临床症状。
