Abstract:
OBJECTIVETo investigate the correlation between ER-a in the liver and cytokines of T lymphocytes subsets and serum signatures in PBC patients.
METHODSThe research is performed with cross-sectional study. 80 PBC women patients without treatment were enrolled in PBC group, 10 healthy women as baseline-matched in healthy-control group, and 20 patients with non-autoimmune liver disease in non-PBC control group. The expression of IL-6, IL-8, IL-22, TNFa, IFNgamma, AMA-M2, Sp100 and gp210 were analyzed in Peripheral Blood using ELISA in all groups, and ER-a of patients were performed on tissues from liver biopsies in PBC group and non-PBC control group with immunohistochemistry. Spearman correlation test were performed on the indices to identified the association of all Parameters. numerical data were compared with Wilcoxon rank-sum test.
RESULTSCompared with healthy-control group, expression of serum cytokines are significantly higher in PBC and non-PBC groups (P less than 0.01), while no significant difference were observed between PBC and non-PBC groups. The positive rate of ER-a in PBC patients liver tissues in PBC group is higher than that in non-PBC group (Z=4.82, P less than 0.01). Expression of ER-a is positively correlated with positive rates of AMA-M2 antibody, Sp100 and gP210 of tissues of PBC patients ( r=0.898, 0.819, 0.814, P less than 0.01). ER-a is positive correlated with the expression of cytokines, among which the coefficient of correlation of IL-22, TNFa, IFNgamma is more than 0.7 (r=0.71, 0.89, 0.82, P less than 0.01), AMA-M2, Sp100, gp210 is negative in serum of non-PBC control group. No obviously correlations were indicated between the expression of ER-a and cytokines.
CONCLUSIONA high level of expression of cytokines in the serum might be one of the factors of etiopathogenesis of PBC.
