BACKGROUND/AIMS: NAFLD with pathological features resembles alcohol-induced liver injury but its pathogenesis remained unclear. IL-6 and IL-8 belonged to pro-inflammatory cytokines and previous studies in alcoholic liver disease showed plasma levels of IL-6 and IL-8 correlated with disease severity. There has been no report regarding plasma levels of IL-6 and Il-8 in Chinese patients with NAFLD.
METHODOLOGY: A total of 94 NAFLD patients and 50 age and sex-matched control subjects were enrolled to compare the clinical characteristics and plasma levels of IL-6/IL-8. IL-6 and IL-8 were determined by commercially available enzyme-linked immunosorbent assay (R&D systems, USA).
RESULTS: As compared with control group, NAFLD patients had significantly higher BMI (p<0.001), fasting sugar (p=0.002), cholesterol (p=0.017), and triglyceride (p<0.001) level. NAFLD patients with abnormal ALT had the highest plasma levels of IL-6 but it did not reach the statistical differences as compared with other groups. Plasma IL-8 measurement showed NAFLD patients with abnormal serum ALT had the highest level (42.87+/-16.58 pg/mL), followed by NAFLD with normal ALT (13.53+/-2.32 pg/mL) and control groups (9.19+/-1.75 pg/mL, p=0.028 as compared with NAFLD with abnormal ALT).
CONCLUSIONS: Through the chemotactic and proinflammatory effects, IL-8 may play a role in the pathogenesis of NAFLD in Chinese patients.
