Diagnostic value of serum soluble mannose receptor for hepatic fibrosis in patients with chronic hepatitis B / 中华临床感染病杂志

ABSTRACT

Objective To assess the diagnostic value of serum soluble mannose receptor (sMR) for hepatic fibrosis in patients with chronic hepatitis B (CHB).Methods Fifty patients with CHB undergoing liver biopsy in the Department of Infectious Diseases , Taizhou Hospital of Zhejiang Province from November 2016 to October 2018 were enrolled, including 28 males and 22 females.According to the stage of liver fibrosis, there were 15 cases without fibrosis (S0 group), 12 cases of mild fibrosis (S1-2 group), and 15 cases of moderate-severe fibrosis ( S3-4 group).Twenty healthy subjects (12 males and 8 females) were recruited as controls.Enzyme linked immunosorbent assay (ELISA) was used to detect the serum hyaluronic acid (HA), laminin (LN), procollagen type ⅢN-terminal peptide (PⅢP), collagen type IV (CIV) and sMR in all groups.One-way ANOVA, Spearman correlation analysis and receiver operating characteristic (ROC) curve were used to analyze the data.Results The serum levels of sMR, HA, LN, CIV and PⅢP in S3-4 group were significantly higher than those in S 0 group ( t＝10.20, 4.69, 8.94, 2.35 and 4.34, respectively; all P＜0.05) and S1-2 group (t＝5.77, 4.23, 7.88, 2.71 and 3.43, respectively; all P＜0.05); and serum sMR level in S1-2 group was higher than that in S0 group ( t ＝6.23, P ＜0.05). Spearman rank correlation demonstrated that serum sMR level was positively correlated with the degree of liver fibrosis (r＝0.860, P＜0.01).ROC curve analysis showed that when 228.69 ng／mL was taken as cut-off value of sMR, its specificity and sensitivity for diagnosis of hepatic fibrosis were 93.3%and 88.6%, respectively.The diagnostic efficacy of sMR was significantly better than that of HA , LN, CIV and PⅢP (Z＝3.179, 3.467, 5.241 and 3.567, respectively; all P＜0.05).When 345.80 ng／mL was taken as cut-off value of sMR, the specificity and sensitivity for diagnosis of moderate to severe hepatic fibrosis were 85.7%and 86.7%, respectively; and its diagnostic efficacy was better than that of HA , CIV and PⅢP (Z＝2.253, 2.475 and 2.092, all P ＜0.05).Conclusion Serum sMR level is associated with the progression of liver fibrosis, it may be used as a new serological marker for non-invasive assessment of liver fibrosis.
