Abstract
BACKGROUND AND OBJECTIVE: Cytokines have been reported to be involved in the cirrhosis and hepatic encephalopathy (HE). Many aspects on the correlation between minimal HE (MHE) and cytokine levels were still unclear. METHODS: Two hundred eighty-nine HBV-infected cirrhotic patients were grouped: non MHE (n = 156), MHE (n = 98) and clinical HE (CHE, n = 213). Another 88 healthy volunteers were included as controls. Clinical and laboratory findings and levels of ten serum cytokines were analyzed. RESULTS: All tested cytokines were significantly elevated in cirrhotic patients and patients with CHE compared with controls. Statistical analysis showed only IL-6, IFNγ and IL-17a were correlated MHE (all three p < 0.001). Multivariate regression analysis indicated that serum IL-6 and IL-17a levels were independent risk factors for MHE. Moreover, all patients with MHE had IL-17a levels higher than 49 pg/mL, whereas those without MHE had IL-17a levels lower than 49 pg/mL. CONCLUSIONS: IL-6, IFNγ, and IL-17a were correlated with MHE in HBV-infected patients. Two independent risk factors (IL-6, IL-17a) for MHE were identified. Our findings pointed out the crucial roles of cytokines in MHE in HBV-infected patients.
