Persistent Airway Obstruction After Virus Infection Is Not Associated With Airway Inflammation	2007-02-28		.txt	text/plain	3828	216	44	Abstract Background:This study examined the contribution of airway inflammation to the delayed lung function recovery that occurs in some people following virus-induced asthma exacerbations. In contrast, during exacerbation, subjects with persistent airway obstruction showed no differences in inflammatory cell counts compared to stable subjects with asthma, nor did cell counts change postexacerbation. Table 3 indicates that during the exacerbation the CCQ was elevated in both the airwayrecovery and the persistent-airway-obstruction groups; then, at 4 to 6 weeks postexacerbation, a similar improvement in virus symptoms was seen in both groups (percentage change in CCQ) [Fig 1] . The poor lung function (percent predicted FEV 1 ) observed during the acute episode significantly improved in the airway-recovery group, with values returning to levels of stable asthma patients postexacerbation. 11 Conversely, patients in the persistent-airway-obstruction group showed a lower airway inflammatory profile during exacerbations similar to those with stable asthma (Fig 2) , and this did not change significantly postexacerbation (Table 4 ).	./cache/cord-284313-rg3krh7d.txt	./txt/cord-284313-rg3krh7d.txt
