BACKGROUND: New-onset complete heart block (CHB) commonly complicates cardiac surgery, for which some patients require a permanent pacemaker (PPM). Little is known regarding late atrioventricular (AV) conduction recovery. OBJECTIVE: To characterize the incidence and predictors of late AV conduction recovery among patients requiring PPM after cardiac surgery. METHODS: Consecutive patients receiving PPM for CHB following cardiac surgery at a high-volume US center from 2000-2014 were evaluated...

BACKGROUND AND AIMS: Persistent HBs antigenemia >1000IU/ml has a possibility of viral reactivation and HCC in 8%, so we investigated the effect of HBV vaccine on HBsAg, IP-10, and recurrence of viremia. METHODS: Group I: inactive carriers(n=100). Group II: CHB exposed to nucleos(t)ides (n=120) till 1year after HBe seroconversion and HBV DNA disappearance in HBeAg positive (n=60) or3years after DNA disappearance in HBeAg negativepatients (n=60). All showed persistent HBs antigenemia...

There were significant differences in response and pharmacokinetic characteristics to the peginterferon α2a treatment among Chronic Hepatitis B (CHB) patients. The aim of this study is to identify factors which could significantly impact the peginterferon α2a pharmacokinetic characteristics in CHB patients. There were 208 blood samples collected from 178 patients who were considered as CHB and had been treated with peginterferon α2a followed by blood concentration measurement and other laboratory tests. The covariates such as demographic and clinical characteristics of the patients were retrieved from medical records...

Hepatitis B virus (HBV) infection induces immune-mediated inflammatory responses. The C-reactive protein (CRP) is an inflammatory marker that is synthesized by the liver. The aim of the present study was to investigate the effect of HBV infection on the expression of CRP and its clinical significance. A reverse transcription-polymerase chain reaction (RT-PCR) analysis was employed to examine the expression of CRP mRNA in the human hepatocellular carcinoma (HCC) cell lines HepG2 and HepG2.2.15. A fully automatic biochemical analyzer was used to examine the serum levels of CRP in patients with chronic HBV infections and in healthy controls...

Special AT-rich sequence-binding protein 1 (SATB1) is a class of nuclear matrix binding protein expressed by T cells and plays an important role in regulatory T cells (Tregs) mediated immune regulation. The immunosuppressive function of Tregs in chronic hepatitis B (CHB) being inhibited by SATB1 has been shown in our previous studies. The objective of this study was to learn the impact of SATB1 on the cellular immune function of CHB. SATB1 isolated from human peripheral blood mononuclear cells (PBMCs) was used as a template of PCR and its product was connected to vector PLV-EF1α-EGFP-N...

PURPOSE: This study aimed to compare the efficacy between tenofovir disoproxil fumarate (TDF) and TDF plus entecavir (ETV) combination therapy in patients with chronic hepatitis B (CHB) with a poor response to ETV. METHODS: We searched the China National Knowledge Infrastructure (CNKI), PubMed, EMBASE, and SCOPE libraries for articles using the keywords chronic hepatitis B virus or CHB or HBV, entecavir or ETV, and tenofovir or TDF. FINDINGS: Five studies (from CNKI and PubMed) with a total of 408 patients met the inclusion criteria: 212 patients in the TDF group and 196 patients in the TDF plus ETV group...

Th17 cells are involved in liver fibrosis by activating hepatic stellate cells (HSCs). We aimed to investigate whether HSCs are able to regulate the function of Th17 cells and to determine the relevant mechanism. Sixty-five patients diagnosed with chronic hepatitis B (CHB) were enrolled in this study. To determine the effect of HSCs on T cells, naïve CD4(+)T cells and Th17 cells were sorted from CHB patients and cultured with or without activated-HSCs, and cytokine expression and gene transcription were analyzed...

There is increasing awareness of the immunologic roles of liver mononuclear populations including myeloid-derived suppressor cells (MDSCs). We took advantage of a large well defined cohort of 148 patients with liver inflammation and 45 health controls to focus on the qualitative and quantitative characteristics of MDSCs. We investigated the frequency, phenotype and functional capacities of MDSCs using peripheral blood MDSCs in a cohort of 55 patients with PBC, 40 with AIH, 39 with CHB, 14 with NAFLD and 45 healthy controls, and thereafter a liver targeted determination in 27 PBC, 27 AIH, 20 CHB, 14 NAFLD and 6 controls...

Current therapies of chronic hepatitis B (CHB) remain limited to pegylated-interferon-alpha (pegIFN-α) or any of the five approved nucleos(t)ide analogues (NA). If viral suppression can be achieved in the majority of patients with the high-barrier-to-resistance new-generation of NA, i.e. entecavir and tenofovir, HBsAg loss is achieved by PEG-IFN-α and/or NA in only 10% of patients, after a 5-year follow-up. Attempts to improve the response by administering two different NA or a combination of NA and PEG-IFN-α have not provided a dramatic increase in the rate of "functional cure"...

BACKGROUND&AIMS: Serum Golgi protein 73 (GP73) is a potential biomarker for fibrosis assessment. We aimed to develop an algorithm based on GP73 and liver stiffness (LS) for further improvement of accuracy for significant fibrosis in patients with antiviral-naïve chronic hepatitis B virus infection. METHODS: Diagnostic accuracy evaluation of GP73 and development of GP73-LS algorithm was performed in training cohort (n = 267) with an independent cohort (n = 133) for validation...

The potential interaction between chronic hepatitis B (CHB) and non-alcoholic fatty liver disease (NAFLD), two of the most prevalent liver diseases worldwide, has not been well-defined. We performed liver stiffness (LS) and controlled attenuation parameter (CAP) measurements using transient elastography in 1202 CHB patients. Of these, 601 steatotic patients were matched with non-steatotic controls in a 1:1 ratio by age, gender, nucleoside analogue treatment status, and treatment duration. Severe fibrosis was defined according to EASL-ALEH criteria, and steatosis defined as CAP ≥222 dB m(-1) ...

BACKGROUND: Entecavir (ETV) and tenofovir disoproxil fumarat (TDF) are the two first-line therapies recommended in the treatment of chronic hepatitis B because of having potent antiviral effect and high genetic barriers against resistance. We aimed to compare efficacy of these drugs and to evaluate predictors of viral suppression.

BACKGROUND AND AIM: Precore (PC) and basal core promoter (BCP) mutations are associated with responses to interferon-based treatment in HBeAg-positive chronic hepatitis B (CHB) patients. Here, we identify viral minority variants in these regions and assess association with response to peginterferon-alfa (Peg-IFN) and adefovir combination therapy. PATIENTS AND METHODS: Ultra-deep pyrosequencing analysis of the BCP and PC region was performed for 89 CHB patients (42 HBeAg-positive; 47 HBeAg-negative), at baseline and during treatment...

OBJECTIVES: To investigate the role of serum hepatitis B core-related antigen (HBcrAg) kinetics in predicting long-term outcome of pegylated interferon (PEG-IFN)-based therapy in patients with HBeAg-negative chronic hepatitis B (CHB). METHODS: 121 Thai patients with HBeAg-negative CHB recruited from a previous randomized trial of 48-week PEG-IFN alone or combined with entecavir were enrolled. HBsAg and HBcrAg levels were serially examined. Paired biopsies at baseline and post-treatment were assessed for intrahepatic cccDNA...

OBJECTIVE: Data comparing hepatitis B virus (HBV) infection in HIV-infected [HIV(+)], and HIV-uninfected [HIV(-)] individuals recruited into the same study are limited. HBV infection status and chronic hepatitis B (cHB) were characterized in a multi-national clinical trial: HIV Prevention Trials Network (HPTN 052). METHOD: HBV infection status at enrollment was compared between HIV(+) (N=1241) and HIV(-) (N=1232) from seven HBV-endemic countries. Hepatitis B e antigen (HBeAg) and plasma HBV DNA were determined in cHB...

The study was to investigate whether serum HBV RNA is a strong surrogate marker for intrahepatic HBV covalently closed circular DNA (cccDNA) when compared with serum HBV DNA, hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) in HBeAg-positive chronic hepatitis B (CHB) patients. Serum HBV RNA, HBV DNA, HBsAg, HBeAg and intrahepatic cccDNA were quantitatively detected at baseline (n=82) and 96 weeks (n=62) after nucleos(t)ide analogues (NUC) treatment in HBeAg-positive CHB patients. Then the correlations between serum HBV RNA, HBV DNA, HBsAg, HBeAg and intrahepatic cccDNA were statistically analyzed...
