High Serum Level of IL-17 in Patients with Chronic Obstructive Pulmonary Disease and the Alpha-1 Antitrypsin PiZ Allele

Table 2

Correlation analysis between A1AT concentrations and proinflammatory cytokine levels in patients with COPD.

	A1AT concentration (mg/l)
	IL-17 (pg/ml)	-0.029	ns
IFN-γ (pg/ml)	0.5191	<0.05
IL-17/IFN-γ	-0.4262	ns
IL-6 (pg/ml)	-0.5678	<0.01
IL-8 (pg/ml)	0.4534	<0.05

COPD: chronic obstructive pulmonary disease; A1AT: alpha-1 antitrypsin.
