简要总结
This is an investigator-initiated study in which Dr. Nadeau wrote the protocol and received funding from an Astra Zeneca grant to direct, perform, and monitor the study on her own with Stanford staff. We hypothesize that the budesonide/formoterol combination improves the efficacy of budesonide alone.
详细描述
The study was designed such that 30 participants would be consented/enrolled into the trial. The intervention would only be applied if the participant developed a viral illness that met eligibility criteria during the study period.
Only 10 of the 30 ppt. consented/enrolled developed a virus and were then treated according to study arm.

研究组 & 干预措施
Budesonide
Combination of budesonide and formoterol. Medications are given according to the package insert and manufacturer's instructions.
Participants that develop a viral upper respiratory illness which induces an asthma exacerbation.within the specified period following enrollment, are randomly assigned 1:1 to either study arm. 5 participants were randomly assigned to the Symbicort study arm.
干预措施: Symbicort (Drug)
Placebo Comparator: Budesonide
Control of budesonide alone. Medication was given according to the package insert and manufacturer's instructions.
Participants that develop a viral upper respiratory illness which induces an asthma exacerbation.within the specified period following enrollment, are randomly assigned 1:1 to either study arm. 5 participants were randomly assigned to the Budesonide study arm.
干预措施: Symbicort (Drug)
结局指标
主要结局
Percent Forced Expiratory Volume in One Second (FEV1)
时间窗: 1 week
Asthma symptoms scores reported as measure of FEV1 - Forced Expiratory Volume in one second * FEV1 is given which is a standard outcome in asthma studies and is validated by the NIH (NHLBI) * FEV1 of less than 80 is indicative of severe asthma, 80-90 is moderate asthma, over 90 is mild asthma http://www.med.umich.edu/1info/FHP/practiceguides/asthma/EPR-3_pocket_guide.pdf
