Serum Interleukin-6 Expression Level and Its Clinical Significance in Patients with Dermatomyositis

Table 1

The demography and the IL-6 levels in DM patients and controls.

Variables	DM	SLE	RA	SS	Healthy controls
	𝑛=23	𝑛=22	𝑛=22	𝑛=16	𝑛=20
Age, years	49 ± 11	41 ± 16	53 ± 14	44 ± 14	45 ± 12
Male/female	9/14	1/21	8/14	1/15	10/10
IL-6, pg/mL	21.5 ± 30.3	43.3 ± 55.6	102.6 ± 82.8	26.7 ± 29.9	1.2 ± 2.6
𝑃 value		0.100	<0.001	0.662	<0.01

𝑃 value was obtained from the statistical comparisons of serum IL-6 between the DM group and the SLE, RA, SS, and healthy groups. DM: dermatomyositis, SLE: systemic lupus erythematosus, RA: rheumatoid arthritis, SS: Sjögren’s syndrome, and IL-6: interleukin-6.
