Prognostic value of plasma IL-27 on biological viability of hepatic cystic echinococcosis

摘要

Objectives To investigate potential biomarkers for distinguishing biological viability of hepatic cystic echinococcosis. Methods Using Luminex assay we measured plasma concentrations of cytokine and chemokine in patients with active and non-active cysts (hepatic cystic echinococcosis (HCE), n = 47) and stable/progressive hepatic alveolar echinococcosis (HAE, n = 38), and in comparable infection-free volunteers (n = 48). Disease progression was staged according to the classification standard. Results Compared with healthy controls, enhanced elevation was found of T helper 22 type cytokine interleukin (IL)-22 and chemokines Eotaxin, interferon-γ inducible protein-10, monocyte chemoattractant protein-1, and stromal cell-derived factor-1α concentrations in HAE patients, and IL-22, growth-related oncogene α, monocyte chemoattractant protein-1, regulated on activation normal T-expressed and secreted, and stromal cell-derived factor-1α concentrations in HCE patients ( P 0.05–0.001). For HCE patients, only IL-27 concentrations in non-active HCE were significantly lower than in active HCE. In logistic regression analysis, IL-27 20.79 pg/mL was an independent risk factor for HCE biological viability with receiver operating characteristic analysis at a 44.23 pg/mL cut-off resulting in 0.72 area under the curve. Conclusions Our findings correlate multiple cytokine and chemokine secretion patterns in HAE and HCE patients with different disease progression stages. IL-27 could serve as a referring biomarker for distinguishing HCE biological viability and provide a preliminary foundation for clinical decision-making.
