Oxidative stress is seen in children with asthma, but is hard to measure. The investigators exploring the utility of using a commercially available assay to measure oxidative stress in the urine in asthmatics. Additionally, the investigators will attempt to prove that oxidative stress is higher in children with acute asthma compared to those with stable asthma and that this stress is also higher in children with more severe clinical asthma exacerbations compared to less severe ones.

Further study details as provided by Stony Brook University:

Primary Outcome Measures:
  • We expect to see increased urinary 8-isoprostane in acute pediatric asthmatics [ Time Frame: Urinary 8-isoprostane levels were measured at the end of subject recruitment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • We expect urinary 8-isoprostane levels to be higher with increased pediatric asthma severity. [ Time Frame: This was calculated at the end of patient recruitment, after urinary 8-isoprostane levels were obtained ] [ Designated as safety issue: No ]
