Baseline metabolites could predict responders with hepatitis B virus-related liver fibrosis for entecavir or combined with FuzhengHuayu tablet

BACKGROUND After receiving entecavir or combined with FuzhengHuayu tablet(FZHY)treatment,some sufferers with hepatitis B virus(HBV)-related liver fibrosis could achieve a histological improvement while the others may fail to improve even worsen.Serum metabolomics at baseline in these patients who were effective in treatment remain unclear.AIM To explore baseline serum metabolites characteristics in responders.METHODS A total of 132 patients with HBV-related liver fibrosis and 18 volunteers as healthy controls were recruited.First,all subjects were divided into training set and validation set.Second,the included patients were subdivided into entecavir responders(E-R),entecavir no-responders(E-N),FZHY+entecavir responders(FR),and FZHY+entecavir no-responders(F-N)following the pathological histological changes after 48 wk’treatments.Then,Serum samples of all subjects before treatment were tested by high performance liquid chromatographytandem mass spectrometry(LC-MS)high-performance LC-MS.Data processing was conducted using multivariate principal component analysis and orthogonal partial least squares discriminant analysis.Diagnostic tests of selected differential metabolites were used for Boruta analyses and logistic regression.RESULTS As for the intersection about differential metabolic pathways between the groups E-R vs E-N and F-R vs F-N,results showed that 4 pathways including linoleic acid metabolism,aminoacyl-tRNA biosynthesis,cyanoamino acid metabolism,alanine,aspartate and glutamate metabolism were screened out.As for the differential metabolites,these 7 intersected metabolites including hydroxypropionic acid,tyrosine,citric acid,taurochenodeoxycholic acid,benzoic acid,2-Furoic acid,and propionic acid were selected.CONCLUSION Our findings showed that 4 metabolic pathways and 7 differential metabolites had potential usefulness in clinical prediction of the response of entecavir or combined with FZHY on HBV fibrotic liver.

Clinical significance of connective tissue growth factor in hepatitis B virus-induced hepatic fibrosis

AIM:To determine the utility of connective tissue growth factor(CCN2/CTGF) for assessing hepatic fibrosis in hepatitis B virus(HBV)-induced chronic liver diseases(CLD-B).METHODS:Enzyme-linked immunosorbent assay was used to measure CCN2 in sera from 107 patients with chronic hepatitis B(CHB) and 39 patients with HBVinduced active liver cirrhosis and 30 healthy individuals.Liver samples from 31 patients with CHB,8 patients with HBV-induced liver cirrhosis and 8 HBV carriers with normal liver histology were examined for transforming growth factor β-1(TGF-β1) or CCN2 mRNA levels by in situ hybridization,and computer image analysis was performed to measure integrated optimal density(IOD) of CCN2 mRNA-positive cells in liver tissues.Histological inflammation grading and fibrosis staging were evaluated by H and E staining and Van Gieson's method.RESULTS:Serum CCN2 concentrations were,respectively,4.0-or 4.9-fold higher in patients with CHB or active liver cirrhosis as compared to healthy individuals(P < 0.01).There was good consistency between the levels of CCN2 in sera and CCN2 mRNA expression in liver tissues(r = 0.87,P < 0.01).The levels of CCN2 in sera were increased with the enhancement of histological fibrosis staging in patients with CLD-B(r = 0.85,P < 0.01).Serum CCN2 was a reliable marker for the assessment of liver fibrosis,with areas under the receiver operating characteristic(ROC) curves(AUC) of 0.94 or 0.85 for,respectively,distinguishing normal liver controls from patients with F1 stage liver fibrosis or discriminating between mild and significant fibrosis.CONCLUSION:Detection of serum CCN2 in patients with CLD-B may have clinical significance for assessment of severity of hepatic fibrosis.

Effects of the Ganning Formula (肝宁方) on Liver Fibrosis in Patients With Chronic Hepatitis B

Objective: To investigate the clinical efficacy and safety of the Ganning formula (肝宁方) for the treatment of liver fibrosis in patients with chronic hepatitis B. Methods: In a multicenter, randomized, controlled clinical trial, 150 patients with liver fibrosis secondary to hepatitis B virus (HBV) infection were randomly assigned in equal numbers to receive either the Ganning formula (a Chinese herbal decoction; active treatment group) or oral entecavir (control group) for two 3-month courses. Patients were monitored for any treatment-induced changes in liver function test parameters (ALT, AST, and GGT), liver fibrosis markers (LN, HA, IV-C, and PCIII), HBV DNA level, hepatosplenic imaging, quality of life scores, or psychological and social functioning scores. Patients were also observed for any adverse effects. Results: After treatment, patients in both groups experienced significant improvements in liver function, HBV DNA load, hepatosplenic B-mode ultrasonography, quality of life, and psychological and social functioning (P<0.05 or P<0.01). Patients receiving the Ganning formula achieved greater improvements in HA, IV-C, quality of life, and psychological and social functioning compared with those on entecavir (P<0.05 or P<0.01). There were no abnormal changes in blood tests, urine, feces, renal function, or electrocardiogram. Additionally, no adverse effects were observed in any patients in either group. Conclusions: The Ganning formula appears to have the potential to inhibit liver fibrosis and therefore improve liver function by inhibiting HBV replication in patients with chronic hepatitis B. Additionally, this formula is helpful in improving quality of life and psychological and social functioning.
