He first report to show that sCD14 in blood is a promising biomarker for diagnosis of NASH and assessing liver inflammation in NASH. NAFLD, which can progress to steatohepatitis and cirrhosis, is perhaps the most common type of chronic liver disease in obese patients [4?]. As effective therapies for NAFLD have not yet been established, the identification of risk factors for disease progression, such as severe liver inflammation, would help to guide the implementation of risk-reduction strategies for these patients [25]. However, discrimination between mild and severe liver inflammation in patients with NASH is very difficult if using imaging modalities alone [26]. Indeed, liver biopsy examination is currently the only method that can precisely diagnose NASH and evaluate liver inflammation in patients with NASH [27]. However, liver biopsy is invasive, expensive, and is associated witha relatively high risk of complications [14]. Moreover, the accuracy of the procedure used to assess the severity of liver fibrosis is questionable because of intra- and inter-observer variation [27?1]. Sampling error has also been reported, even in patients with NASH [32]. Therefore, a non-invasive, reproducible, conceptually simple, and highly reliable test is needed to diagnose NASH and evaluate the severity of liver inflammation in patients 18204824 serum sCD14 levels increase during the systemic response to bacterial invasion and endotoxin. Actually, we showed that sCD14 was increased in the culture medium of RAW264.7 cells after LPS treatment, suggesting that sCD14 may be shed from mCD14 in RAW264.7 cells under the effect of LPS. Here, we presented a hypothesis that the increased sCD14 levels in patients with NASH might reflect the severity ofsCD14 and Liver Inflammation in NASHFigure 1. Serum sCD14 levels, liver inflammation and hepatic CD14 expression. (A) Serum sCD14 levels in control subjects and patients with NAFLD. The graph shows the interquartile range (box), median (the line), and range (lines) of serum sCD14 levels. The median (range) values (ng/ dl) are 24.3 (13.3?2.4), 27.5 (9.21?4.2), and 32.2 (17.9?4.2) for control subjects (n = 21), not NASH (n = 48), and NASH (n = 65), respectively. Statistical significance was determined by analysis of variance with Scheffe’s correction for multiple testing. *P,0.05. (B) Receiver operating characteristic (ROC) curve and area under the ROC curve (AUROC) for distinguishing between not NASH (n = 48) including control subjects (n = 21) and NASH (n = 65) using serum sCD14 level. (C) Relationship between serum sCD14 and the grade of liver inflammation in patients with NAFLD. Serum sCD14 levels are significantly correlated with the grade of liver inflammation (Spearman’s r = 0.498, P,0.001). (D) Relationship between serum sCD14 and hepatic CD14 mRNA Anlotinib web expression in patients with NAFLD. Serum sCD14 levels are significantly correlated with hepatic CD14 mRNA expression levels (Spearman’s r = 0.552, P,0.001). The correlation was determined in 69 patients with NAFLD patients. doi:10.1371/journal.pone.0065211.gliver inflammation. Consistent with this hypothesis, we observed as significant association between serum sCD14 levels and definite NASH or the grade of liver inflammation in histological sections in liver biopsy-confirmed NAFLD.
