Serum inflammatory mediators in acute asthma

	Acute virus-induced asthma	Acute non–virus-induced asthma	Acute virus-induced asthma group at recovery	Acute non–virus-induced asthma group at recovery
IP-10	604∗† (450-1536)	167† (141.5-168)	18.4 (4.5-43.1)	16.3 (3.9-34.2)
IL-6	6.6 (6.55-30.7)	16.5† (6.6-20.5)	4.5 (3.8-6.6)	4.1 (3.8-6.6)
IL-8	22.4† (21.4-27.2)	21.2† (20.2-25.2)	12.1 (6.1-16.7)	8.4 (4.8-12.6)
TNF-α	14† (12-15)	109.8† (13.5)	4.3 (2.8-5.1)	3.4 (2.8-4.4)

All values are expressed as medians and interquartile ranges.

^∗Significantly different from non–virus-induced acute asthma at presentation (P < .001, Mann-Whitney U test).

^†Significantly different from results obtained at acute visit (P < .01, Wilcoxon signed-rank test).
