Polymorphisms of interleukin-1B and interleukin-1 receptor antagonist genes in patients with chronic hepatitis B

Table 3 Association between IL-1B, IL-RN genotypes and HBV copies in chronic hepatitis B patients

Subgroup	n	IL-1B genotype (%)				IL-1RN genotype (%)
		CCa	CT	TT	1/1	1/2	2/2	1/4
I	104	31 (29.8)	49 (47.1)	24 (23.1)	93 (89.4)	9 (8.7)	0	2 (1.9)
II	86	14 (16.3)	45 (52.3)	27 (31.4)	76 (88.3)	8 (9.3)	1 (1.2)	1 (1.2)

HBV-DNA ≤ 1×10³ copies/mL as I, HBV-DNA > 1×10³ copies/mL as II,

^asubgroup I vs subgroup II, χ² = 4.77, P = 0.029.
