BACKGROUND AND AIM: As liver fibrosis is the result of persistent
necroinflammation in the liver, pro-inflammatory cytokines secreted in response
to cell injury have a central role in the pathogenesis of liver fibrosis. We
aimed to investigate the association of cytokine gene polymorphism and liver
fibrosis among Chinese patients with chronic hepatitis B.
METHODS: Polymorphisms at interleukin-10 (IL-10-627, -1117), interleukin-1-beta
(IL-1beta-511, -31, -3964), interleukin-1 receptor antagonist (IL-1RN), and tumor
necrosis factor-alpha (TNF-alpha-308, -238) among Chinese chronic hepatitis B
patients were determined. Severe liver fibrosis was defined as Ishak fibrosis
score = 4 (of 6).
RESULTS: Fifty-nine of 273 (22%) patients had severe fibrosis. The distribution
of genotypes for IL-10-627 was CC (11%), CA (41%), and AA (48%). The CC genotype
at IL-10-627 was protective against severe fibrosis (odds ratio (OR) 0.11; 95% CI
0.014-0.82; P = 0.032). After adjusted for baseline variables, the adjusted OR of
CC genotypes at IL-10-627 for severe fibrosis was 0.063 (95% CI 0.06-0.64; P =
0.063). Other gene polymorphisms at IL-1beta, IL-1RN, TNF-alpha, and IL-10 had no
significant association with severe fibrosis. Weak linkage disequilibrium was
observed between IL-10-627 and IL-10-1117 with linkage disequilibrium coefficient
of 0.12 (P < 0.001). The distribution of haplotypes of IL-10-1117 and IL-10-627
was A-A (69%), A-C (26%), and G-C (5%). High and intermediate IL-10 production
(A-C and G-C) haplotypes were protective against severe fibrosis (OR 0.62; 95% CI
0.39-0.99; P = 0.046).
CONCLUSIONS: High production genotype and haplotypes of IL-10 were associated
with less severe liver fibrosis in chronic hepatitis B in Chinese.
