Factors associated with persistent positive in HBV DNA level in patients with chronic Hepatitis B receiving entecavir treatment.

Introduction: The clinical significance of persistent positive in Hepatitis B Virus (HBV) DNA level in patients receiving antiviral therapy is not well known. We investigated factors associated with persistent viremia (PV) in patients with chronic hepatitis B (CHB) given 78-week entecavir. Methods: A total of 394 treatment-naïve CHB patients who had undergone liver biopsy at baseline and week 78 of treatment were analyzed in this prospective multicentre study. We identified patients with PV (above the lower limit of quantification, 20 IU/ml) after 78 weeks of entecavir therapy. Stepwise, forward, multivariate regression analyses of specified baseline parameters were apllied to identify factors associated with PV. Futhermore, we assessed the incidence of hepatocellular carcinoma (HCC) in all patients using models of the risk of HCC development. Results: Of the 394 patients, 90 (22.8%) still with PV after 78-week antiviral treatment. Factors associated significantly with PV (vs complete virological response, CVR) were HBV DNA level ≥8 log10 IU/mL (OR, 3.727; 95% CI, 1.851-7.505; P < 0.001), Anti-HBc level < 3 log10 IU/mL (OR, 2.384; 95% CI, 1.223-4.645; P=0.011), and HBeAg seropositivity (OR, 2.871; 95% CI, 1.563-5.272; P < 0.001). Patients with PV were less likely to have fibrosis progression and HCC development than those with the CVR. Of the 11 HBeAg-positive patients with HBV DNA level ≥8 log10 IU/mL and Anti-HBc level < 3 log10 IU/mL at baseline, 9 (81.8%) had persistent positivity in HBV DNA level and 0 had fibrosis progression at week 78 of treatment. Discussion: In conclusion, HBV DNA level ≥8 log10 IU/mL, Anti-HBc level < 3 log10 IU/mL and HBeAg seropositivity at baseline contribute to PV in patients with CHB receiving 78-week antiviral treatment. In addition, the rate of fibrosis progression and the risk of HCC development in patients with PV were kept low. The complete protocol for the clinical trial has been registered at clinicaltrials.gov (NCT01962155 and NCT03568578).

An-Luo-Hua-Xian Pill Improves the Regression of Liver Fibrosis in Chronic Hepatitis B Patients Treated with Entecavir.

Background and Aims: Chronic hepatitis B (CHB) can cause liver fibrosis and lead to cirrhosis and cancer. As the effectiveness of antiviral therapy to reverse liver fibrosis is limited, We aimed to evaluate the effect of An-Luo-Hua-Xian pill (ALHX) on fibrosis regression in CHB patients treated with entecavir (ETV). Methods: Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX (ETV+ALHX) between October 1, 2013 and December 31, 2020. Demographic, laboratory, and liver histology data before and after 78 weeks of treatment were collected. The Ishak fibrosis score (F) was used and fibrosis regression required a decrease in F of ≥1 after treatment. Results: A total of 780 patients were enrolled, and 394 with a second liver biopsy after treatment were included in the per-protocol population, 132 in ETV group and 262 in ETV+ALHX group. After 78 weeks of treatment, the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients: 124/211 (58.8%) vs. 45/98 (45.9%), p=0.035. The percentage of patients with a decreased liver stiffness measurement (LSM) was higher in the ETV+ALHX group: 156/211 (73.9%) vs. 62/98 (63.%), p=0.056. Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression [odds ratio (OR)=1.94, p=0.018], and a family history of hepatocellular carcinoma was on the contrary. (OR=0.41, p=0.031). Conclusions: ETV combined with ALHX increased liver fibrosis regression in CHB patients.

Influence of weight management on the prognosis of steatohepatitis in chronic hepatitis B patients during antiviral treatment.

BACKGROUND: Although concomitant nonalcoholic steatohepatitis (NASH) is common in chronic hepatitis B (CHB), the impact of viral factors on NASH and the outcome of CHB patients concomitant with NASH remain unclear. We aimed to investigate the outcomes of NASH in CHB patients receiving antiviral treatment. METHODS: In the post-hoc analysis of a multicenter trial, naïve CHB patients receiving 72-week entecavir treatment were enrolled. We evaluated the biochemical, viral and histopathological responses of these patients. The histopathological features of NASH were also evaluated, using paired liver biopsies at baseline and week 72. RESULTS: A total of 1000 CHB patients were finally enrolled for analysis, with 18.2% of whom fulfilling the criteria of NASH. A total of 727 patients completed entecavir antiviral treatment and received the second biopsy. Serum HBeAg loss, HBeAg seroconversion and HBV-DNA undetectable rates were similar between patients with or without NASH (P > 0.05). Among patients with NASH, the hepatic steatosis, ballooning, lobular inflammation scores and fibrosis stages all improved during follow-up (all P < 0.001), 46% (63/136) achieved NASH resolution. Patients with baseline body mass index (BMI) ≥ 23 kg/m2 (Asian criteria) [odds ratio (OR): 0.414; 95% confidence interval (95% CI): 0.190-0.899; P = 0.012] and weight gain (OR: 0.187; 95% CI: 0.050-0.693; P = 0.026) were less likely to have NASH resolution. Among patients without NASH at baseline, 22 (3.7%) developed NASH. Baseline BMI ≥ 23 kg/m2 (OR: 12.506; 95% CI: 2.813-55.606; P = 0.001) and weight gain (OR: 5.126; 95% CI: 1.674-15.694; P = 0.005) were predictors of incident NASH. CONCLUSIONS: Lower BMI and weight reduction but not virologic factors determine NASH resolution in CHB. The value of weight management in CHB patients during antiviral treatment deserves further evaluation.

Serum N-glycan markers for diagnosing liver fibrosis induced by hepatitis B virus.

BACKGROUND: Hepatitis B virus (HBV) infection is the primary cause of hepatitis with chronic HBV infection, which may develop into liver fibrosis, cirrhosis and hepatocellular carcinoma. Detection of early-stage fibrosis related to HBV infection is of great clinical significance to block the progression of liver lesion. Direct liver biopsy is regarded as the gold standard to detect and assess fibrosis; however, this method is invasive and prone to clinical sampling error. In order to address these issues, we attempted to find more convenient and effective serum markers for detecting HBV-induced early-stage liver fibrosis. AIM: To investigate serum N-glycan profiling related to HBV-induced liver fibrosis and verify multiparameter diagnostic models related to serum N-glycan changes. METHODS: N-glycan profiles from the sera of 432 HBV-infected patients with liver fibrosis were analyzed. Significant changed N-glycan levels (peaks) (P < 0.05) in different fibrosis stages were selected in the modeling group, and multiparameter diagnostic models were established based on changed N-glycan levels by logistic regression analysis. The receiver operating characteristic (ROC) curve analysis was performed to evaluate diagnostic efficacy of N-glycans models. These models were then compared with the aspartate aminotransferase to platelet ratio index (APRI) , fibrosis index based on the four factors (FIB-4), glutamyltranspeptidase platelet albumin index (S index), GlycoCirrho-test, and GlycoFibro-test. Furthermore, we combined multiparameter diagnostic models with alanine aminotransferase (ALT) and platelet (PLT) tests and compared their diagnostic power. In addition, the diagnostic accuracy of N-glycan models was also verified in the validation group of patients. RESULTS: Multiparameter diagnostic models constructed based on N-glycan peak 1, 3, 4 and 8 could distinguish between different stages of liver fibrosis. The area under ROC curves (AUROCs) of Model A and Model B were 0.890 and 0.752, respectively differentiating fibrosis F0-F1 from F2-F4, and F0-F2 from F3-F4, and surpassing other serum panels. However, AUROC (0.747) in Model C used for the diagnosis of F4 from F0-F3 was lower than AUROC (0.795) in FIB-4. In combination with ALT and PLT, the multiparameter models showed better diagnostic power (AUROC = 0.912, 0.829, 0.885, respectively) when compared with other models. In the validation group, the AUROCs of the three combined models (0.929, 0.858, and 0.867, respectively) were still satisfactory. We also applied the combined models to distinguish adjacent fibrosis stages of 432 patients (F0-F1/F2/F3/F4), and the AUROCs were 0.917, 0.720 and 0.785. CONCLUSION: Multiparameter models based on serum N-glycans are effective supplementary markers to distinguish between adjacent fibrosis stages of patients caused by HBV, especially in combination with ALT and PLT.

A multi-center randomized double-blind placebo-controlled trial of Xiongshao Capsule in preventing restenosis after percutaneous coronary intervention: a subgroup analysis of senile patients.

OBJECTIVE: To evaluate the safety and efficacy of Xiongshao Capsule (XS), consisting of Chuangxiongol and paeoniflorin, in preventing restenosis after percutaneous coronary intervention (PCI) in senile coronary heart disease (CHD) patients. METHODS: A multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 CHD patients were randomly assigned to treatment with oral administration of XS, or a placebo for 6 months after successful PCI. A clinical follow-up was performed at 1, 3 and 6 months after PCI and an angiographic follow-up was scheduled at 6 months. The primary endpoint was angiographic restenosis defined as a luminal stenosis ≥ 50% in follow-up. The secondary endpoints were combined incidence of death, target lesion nonfatal myocardial infarction, repeat target-vessel angioplasty, and coronary artery bypass graft surgery (CABG). The follow-up for the above clinical endpoint events was continued to 1 year after PCI. RESULTS: The subgroup analysis of 152 senile patients (68 cases angiographic follow-up) showed that the restenosis rates tended to reduce in the XS group as compared with that in the placebo group (24.32% vs. 38.71%, P > 0.05), and the minimum lumen diameter (MLD) significantly increased in the follow-up (2.15 ± 0.84 for XS vs. 1.73 ± 0.91 for placebo, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in the XS group (4.11% and 12.33%) as compared with those in the placebo group (17.72% and 43.04%), but there was no significant difference in the combined incidence of clinical outcomes (6.85% in the XS group vs. 11.39% in the placebo group, P > 0.05). No significant adverse reactions occurred within the 6-month follow-up period in the XS group. CONCLUSION: Administration of XS in addition to standardized Western medication for 6 months is demonstrated to be safe and effective in reducing post-PCI recurrent angina and inhibiting luminal restenosis after PCI in senile CHD patients.

[Occult hepatitis B virus infection in chronic viral hepatitis patients with non-A to E hepatitis virus infection].

OBJECTIVE: To observe the status of occult hepatitis B virus infection in chronic viral hepatitis patients with non-A to E hepatitis virus infection and explore the diagnostic value of fluorescence quantitative polymerase chain reaction (FQ-PCR) technique for occult hepatitis B virus infection. METHODS: The amount of HBV-DNA in serum and liver tissue from 57 patients with non-A to E hepatitis virus infection who were diagnosed as chronic viral hepatitis by Menghini method liver biopsy were detected by using FQ-PCR technique, then the relation between the viral load of HBV DNA in liver tissue and hepatic inflammatory activity were analyzed. RESULTS: Thirteen (22.81%), 22 (38.60%) patients were positive for HBV DNA in serum and liver tissue, respectively. The positive rate and the level of HBV DNA quantity in liver tissue were significantly higher than those in serum; HBV DNA was found positive in both serum and liver tissue in 13 cases, negative in both serum and liver tissue in 35, positive in liver tissue but negative in serum in 9, and in none of the cases HBV DNA was positive in serum but negative in liver tissue (P < 0.01). The logarithmic value of HBV DNA from 13 patients in liver tissue and in serum was respectively: (6.62 +/- 1.21) copies/g vs.(4.03 +/- 1.06) copies/ml, P < 0.01. The hepatic lesions of all HBV DNA positive patients were active pathologic changes, but the level of HBV DNA in liver tissue was not significantly correlated with the grade of hepatic inflammation activity (P > 0.05). CONCLUSION: Occult HBV infection is the etiology of part of the chronic viral hepatitis patients with non-A-E hepatitis virus infection. Missed diagnosis will occur if diagnosis of hepatitis B is only based on detection of serum HBV markers. It is useful for improvement of the diagnostic level of HBV infection via detection of HBV DNA quantitatively in serum especially in liver tissue of chronic viral hepatitis patients with non-A-E hepatitis virus infection by using FQ-PCR technique. The chronic viral hepatitis patients with occult HBV infection should be also given effective anti-viral therapy.

[Role of hepatitis C virus superinfection in hepatic pathologic changes of patients with chronic hepatitis B: a retrospective short-term and long-term comparative study].

OBJECTIVE: To observe the effect of hepatitis C virus (HCV) superinfection on the short-term and long-term hepatic pathological changes in patients with chronic hepatitis B (CHB). METHODS: HCV-RNA of twice corresponding period serum samples was detected via reverse transcription polymerase chain reaction assay from 230 patients with CHB for whom liver biopsy was performed at an interval of 0.5-15 years, respectively. The hepatic pathological changes of the patients with CHB who were serum HCV-RNA positive at the beginning of observation and persistently positive between the starting and ending of observation were respectively compared with those of serum HCV-RNA negative and persistently negative patients. RESULTS: 41 patients (17.83%) were positive for serum HCV-RNA at the beginning of observation. There were significant differences in the severity of hepatic inflammatory activity grade and fibrosis stage between serum HCV-RNA positive and negative patients with CHB (P < 0.05). Twenty-nine patients were persistently positive for serum HCV-RNA in the beginning and end of observation. Compared with persistently negative patients who were 116 patients selected from the above-mentioned 230 patients and they were comparable with HCV-RNA persistently positive patients in mean follow-up time, age and sex, the long-term progression of hepatic inflammatory activity grade and fibrosis stage in persistently positive patients were more speedy (P < 0.01). CONCLUSION: HCV superinfection worsens the hepatic pathological changes of patients with CHB and speeds up its progression.
