Liver Int. 2017 Jan;37(1):35-44 Authors: Zou X, Zhu MY, Yu DM, Li W, Zhang DH, Lu FJ, Gong QM, Liu F, Jiang JH, Zheng MH, Kuno A, Narimatsu H, Zhang Y, Zhang XX Abstract BACKGROUND & AIMS: Accurate evaluation of liver fibrosis is crucial for predicting progression of chronic hepatitis B virus (HBV) infection. We assessed the utility of a novel fibrosis glycobiomarker Wisteria floribunda agglutinin-positive Mac-2-binding protein (WFA(+) -M2BP) for evaluating liver fibrosis and disease progression in patients with chronic HBV infection. METHODS: We enrolled 774 patients with chronic HBV infection, with or without fibrosis, diagnosed by liver biopsy/FibroScan. Patients who underwent liver biopsy (n = 297) were divided into training (n = 221) and validation (n = 76) groups. Serum WFA(+) -M2BP values were measured and compared with FIB-4 index, aspartate aminotransferase (AST)-to-platelet ratio (APRI) and AST-to-alanine aminotransferase ratio (AAR) using receiver-operating characteristic (ROC) analysis. RESULTS: Serum WFA(+) -M2BP levels increased significantly with fibrosis progression (P < 0.0001). Area under the ROC curve of WFA(+) -M2BP for diagnosing significant fibrosis was higher than that of FIB-4 (P = 0.198), APRI (P = 0.017) and AAR (P < 0.001), with sensitivity and specificity in the training set of 60.5% and 79.8% and validation set of 59.5% and 82.1%, respectively. Serum WFA(+) -M2BP levels were significantly correlated with FibroScan values (P < 0.0001) and improved the accuracy of FibroScan in assessing significant fibrosis. Changes in WFA(+) -M2BP levels were parallel with those in FibroScan values during nucleot(s)ide analogues therapy in patients with chronic HBV infection. CONCLUSIONS: WFA(+) -M2BP is an accurate serum indicator for assessing early stages of liver fibrosis and may monitor regression of fibrosis during the treatment of chronic HBV infection. WFA(+) -M2BP provides a simple and reliable alternative or complementary method to liver biopsy and FibroScan. PMID: 27300763 [PubMed – indexed for MEDLINE]
