[PMID: 38049630 PMCID: PMC10695938 DOI: 10.1038/s41598-023-48812-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 11/30/2023] [Indexed: 12/06/2023] [Imported: 12/10/2023] Open
Abstract
Aspirin, as a widely used anti-inflammatory drug, has been shown to exert anti-cancer effects in a variety of cancers. PD-L1 is widely expressed in tumor cells and inhibits anti-tumor immunity. This study aims to clarify whether aspirin exerts its anti-hepatocellular carcinoma (HCC) effect by inhibiting PD-L1 expression. The rat model of HCC was established by drinking 0.01% diethylnitrosamine (DEN), and aspirin was given by gavage. The gross and blood biochemical indexes of rats were analyzed. CD4 and CD8 expression in liver tissues were investigated by immunohistochemistry. CCK8 assay was used to detect the inhibitory effect of aspirin on the proliferation of HCC cells. The regulatory effect of aspirin on PD-L1 expression was analyzed by western blot. As a result, the tumor number and liver weight ratio in the DEN + ASA group were lower than those in the DEN group (P = 0.006, P = 0.046). Compared with the DEN group, the expression of CD4 in the DEN + ASA group was significantly increased, while CD8 was decreased (all P < 0.01). Biochemical indexes showed that there were differences in all indexes between the DEN and control group (P < 0.05). The levels of DBIL, ALP, and TT in the DEN + ASA group were lower than those in the DEN group (P = 0.038, P = 0.042, P = 0.031). In the DEN group, there was an obvious fibrous capsule around the tumor, and the portal vein was dilated. The pathological changes were mild in the DEN + ASA group. Compared with the DEN group, the expression of PD-L1 in liver tissue of the DEN + ASA group was decreased (P = 0.0495). Cytological experiments further showed that aspirin could inhibit the proliferation and PD-L1 expression in Hep G2 and Hep 3B cells. In conclusion, aspirin can inhibit the proliferation of HCC cells and reduce tumor burden by reducing inflammation and targeting PD-L1.

Short-Term Peg-IFN α-2b Re-Treatment Induced a High Functional Cure Rate in Patients with HBsAg Recurrence after Stopping Peg-IFN α-Based Regimens. J Clin Med 2023; 12:jcm12010361. [PMID: 36615161 PMCID: PMC9821570 DOI: 10.3390/jcm12010361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 12/22/2022] [Accepted: 12/23/2022] [Indexed: 01/04/2023] [Imported: 09/25/2023] Open
Abstract
Little is known about the treatment of patients with hepatitis B surface antigen (HBsAg) recurrence after being clinically cured by peginterferon alpha(peg-IFN-α)-based regimens. This study aimed to investigate the efficacy and safety of peg-IFNα-2b in re-treating patients with HBsAg recurrence after stopping peg-IFN α-based regimens. In this two-center, prospective observational study, 33 patients with HBsAg recurrence after stopping peg-IFN α-based regimens were enrolled and re-treated with an individualized course of peg-IFN α-2b. The hepatitis B virus (HBV) vaccine could be injected immediately after HBsAg clearance, according to patients’ willingness. All patients were monitored and followed-up for 48 weeks after peg-IFN α-2b re-treatment stop. The primary endpoint was HBsAg clearance at the end of follow-up. At baseline, all patients had HBsAg levels of <10 IU/mL and undetectable HBV DNA, with the median HBsAg level of 1.66 (0.56−2.87) IU/mL. After a median of 24 (24−30) weeks of peg-IFN α-2b re-treatment, 87.9% (29/33) of the patients achieved HBsAg clearance again and 66.7% (22/33) of the patients achieved HBsAg seroconversion. At the end of follow-up, the HBsAg clearance and HBsAg seroconversion rates decreased to 78.8% (26/33) and 51.5% (17/33), respectively. Furthermore, 88.9% (16/18) of the patients with HBsAg clearance benefited from receiving the HBV vaccine therapy. Generally, both peg-IFN α-2b and HBV vaccine therapy were well tolerated. A high functional cure rate can be achieved by a short-course of peg-IFN α-2b re-treatment in patients with HBsAg recurrence after stopping peg-IFN α-based regimens. Furthermore, injecting HBV vaccine is beneficial after HBsAg clearance.

Associations of psychological wellbeing with COVID-19 hospitalization and mortality in adults aged 50 years or older from 25 European countries and Israel. Front Public Health 2023; 11:1124915. [PMID: 37213603 PMCID: PMC10194836 DOI: 10.3389/fpubh.2023.1124915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 03/30/2023] [Indexed: 05/23/2023] [Imported: 09/25/2023] Open
Abstract
Background Lower psychological wellbeing is associated with poor outcomes in a variety of diseases and healthy populations. However, no study has investigated whether psychological wellbeing is associated with the outcomes of COVID-19. This study aimed to determine whether individuals with lower psychological wellbeing are more at risk for poor outcomes of COVID-19. Methods Data were from the Survey of Health, Aging, and Retirement in Europe (SHARE) in 2017 and SHARE's two COVID-19 surveys in June-September 2020 and June-August 2021. Psychological wellbeing was measured using the CASP-12 scale in 2017. The associations of the CASP-12 score with COVID-19 hospitalization and mortality were assessed using logistic models adjusted for age, sex, body mass index, smoking, physical activity, household income, education level, and chronic conditions. Sensitivity analyses were performed by imputing missing data or excluding cases whose diagnosis of COVID-19 was solely based on symptoms. A confirmatory analysis was conducted using data from the English Longitudinal Study of Aging (ELSA). Data analysis took place in October 2022. Results In total, 3,886 individuals of 50 years of age or older with COVID-19 were included from 25 European countries and Israel, with 580 hospitalized (14.9%) and 100 deaths (2.6%). Compared with individuals in tertile 3 (highest) of the CASP-12 score, the adjusted odds ratios (ORs) of COVID-19 hospitalization were 1.81 (95% CI, 1.41-2.31) for those in tertile 1 (lowest) and 1.37 (95% CI, 1.07-1.75) for those in tertile 2. As for COVID-19 mortality, the adjusted ORs were 2.05 (95% CI, 1.12-3.77) for tertile 1 and 1.78 (95% CI, 0.98-3.23) for tertile 2, compared with tertile 3. The results were relatively robust to missing data or the exclusion of cases solely based on symptoms. This inverse association of the CASP-12 score with COVID-19 hospitalization risk was also observed in ELSA. Conclusion This study shows that lower psychological wellbeing is independently associated with increased risks of COVID-19 hospitalization and mortality in European adults aged 50 years or older. Further study is needed to validate these associations in recent and future waves of the COVID-19 pandemic and other populations.

Efficacy and mechanism of intermittent fasting in metabolic associated fatty liver disease based on ultraperformance liquid chromatography-tandem mass spectrometry. Front Nutr 2022; 9:838091. [PMID: 36451744 PMCID: PMC9704542 DOI: 10.3389/fnut.2022.838091] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2021] [Accepted: 09/20/2022] [Indexed: 07/30/2023] [Imported: 08/29/2023] Open
Abstract
OBJECTIVES Drug treatment of metabolic associated fatty liver disease (MAFLD) remains lacking. This study analyzes the efficacy and mechanism underlying intermittent fasting combined with lipidomics. METHODS Thirty-two male rats were randomly divided into three groups: Normal group, administered a standard diet; MAFLD group, administered a 60% high-fat diet; time-restricted feeding (TRF) group, administered a 60% high-fat diet. Eating was allowed for 6 h per day (16:00-22:00). After 15 weeks, liver lipidomics and other indicators were compared. RESULTS A total of 1,062 metabolites were detected. Compared with the Normal group, the weight, body fat ratio, aspartate aminotransferase, total cholesterol, low-density cholesterol, fasting blood glucose, uric acid, and levels of 317 lipids including triglycerides (TG) (17:0-18:1-20:4) were upregulated, whereas the levels of 265 lipids including phosphatidyl ethanolamine (PE) (17:0-20:5) were downregulated in the MAFLD group (P < 0.05). Compared with the MAFLD group, the weight, body fat ratio, daily food intake, and levels of 253 lipids including TG (17:0-18:1-22:5) were lower in the TRF group. Furthermore, the levels of 82 lipids including phosphatidylcholine (PC) (20:4-22:6) were upregulated in the TRF group (P < 0.05), while serum TG level was increased; however, the increase was not significant (P > 0.05). Enrichment analysis of differential metabolites showed that the pathways associated with the observed changes mainly included metabolic pathways, regulation of lipolysis in adipocytes, and fat digestion and absorption, while reverse-transcription polymerase chain reaction showed that TRF improved the abnormal expression of FAS and PPARα genes in the MAFLD group (P < 0.05). CONCLUSION Our results suggest that 6 h of TRF can improve MAFLD via reducing food intake by 13% and improving the expression of genes in the PPARα/FAS pathway, thereby providing insights into the prevention and treatment of MAFLD.

Abstract
Background and Aim Ropeginterferon alfa‐2b is a novel mono‐pegylated, extra‐long‐acting interferon. It is administered infrequently and showed good tolerability and clinical activity for the chronic hepatitis B or C treatment in our previous Phase 2 clinical trials. This study aims to validate the potency and safety of this novel agent in a Phase 3 chronic viral hepatitis setting. Methods Patients with chronic hepatitis C genotype 2 were randomized to receive subcutaneous injections of ropeginterferon alfa‐2b biweekly or the conventional pegylated interferon alfa‐2b weekly for 24 weeks, combined with ribavirin. The primary endpoint was to assess the safety and antiviral potency of ropeginterferon alfa‐2b by the non‐inferiority in sustained virologic response at 12 weeks after treatment. Results A total of 222 patients were enrolled. Ropeginterferon alfa‐2b group showed a favorable safety profile. Side effects that were generally associated with prior interferon therapies, including neutropenia, asthenia, fatigue, alopecia, dizziness, decreased appetite, nausea, flu‐like symptoms including myalgia, pyrexia, and headache, and administration site reactions, were notably less in the ropeginterferon alfa‐2b group. The cumulative incidence of adverse events of special interest was also notably higher in the control group. The primary endpoint was met and ropeginterferon alfa‐2b showed a better SVR12 rate of 79.8% than 71.9% of the control group. Conclusion Ropeginterferon alfa‐2b is efficacious and has a favorable safety profile as compared with the conventional pegylated interferon alfa‐2b. This study together with previous Phase 2 data validated ropeginterferon alfa‐2b to be a new treatment option for chronic hepatitis C genotype 2.

VCAN, expressed highly in hepatitis B virus-induced hepatocellular carcinoma, is a potential biomarker for immune checkpoint inhibitors. World J Gastrointest Oncol 2022; 14:1933-1948. [PMID: 36310697 PMCID: PMC9611428 DOI: 10.4251/wjgo.v14.i10.1933] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 07/23/2022] [Accepted: 09/12/2022] [Indexed: 02/05/2023] [Imported: 08/29/2023] Open
Abstract
BACKGROUND As a proteoglycan, VCAN exists in the tumor microenvironment and regulates tumor proliferation, invasion, and metastasis, but its role in hepatocellular carcinoma (HCC) has not yet been elucidated.
AIM To investigate the expression and potential mechanism of action of VCAN in HCC.
METHODS Based on The Cancer Genome Atlas Liver Hepatocellular Carcinoma dataset, we explored the correlation between VCAN expression and clinical features, and analyzed the prognosis of patients with high and low VCAN expression. The potential mechanism of action of VCAN was explored by Gene Ontology analysis, Kyoto Encyclopedia of Genes and Genomes analysis, and gene set enrichment analysis. We also explored immune cell infiltration, immune checkpoint gene expression, and sensitivity of immune checkpoint [programmed cell death protein 1 (PD-1)/cytotoxic T lymphocyte antigen 4 (CTLA4)] inhibitor therapy in patients with different VCAN expression. VCAN mRNA expression and VCAN methylation in peripheral blood were tested in 100 hepatitis B virus (HBV)-related patients (50 HCC and 50 liver cirrhosis).
RESULTS VCAN was highly expressed in HCC tissues, which was associated with a poor prognosis in HCC patients. No significant difference was found in VCAN mRNA expression in blood between patients with HBV-related cirrhosis and those with HCC, but there was a significant difference in VCAN methylation between the two groups. The correlation between VCAN and infiltrations of several different tumor immune cell types (including B cells, CD8+ T cells, and eosinophils) was significantly different. VCAN was strongly related to immune checkpoint gene expression and tumor mutation burden, and could be a biomarker of sensitivity to immune checkpoint (PD1/CTLA4) inhibitors. In addition, VCAN mRNA expression was associated with hepatitis B e antigen, HBV DNA, white blood cells, platelets, cholesterol, and coagulation function.
CONCLUSION High VCAN level could be a possible biomarker for poor prognosis of HCC, and its immunomodulatory mechanism in HCC warrants investigation.

Abstract
INTRODUCTION AND AIM The use of aspirin is a potential protective factor against the development of hepatocellular carcinoma (HCC). Therefore, we conducted a meta-analysis to evaluate the contribution of aspirin to the risk of HCC. METHODS We searched for PubMed and EMBASE through September 2021. RESULTS Eighteen studies (16 cohort, 2 case-control) were included. Aspirin users were less likely to develop HCC than nonusers [adjusted odds ratio (OR), 0.54; 95% confidence interval (CI): 0.44-0.66]. Stratified analysis showed that aspirin reduced the risk of HCC in Asian and Western populations (OR, 0.59 vs. 0.67). Besides, aspirin has protective effects against HCC after hepatitis B virus (OR, 0.70; 95% CI: 0.52-0.93) and hepatitis C virus infections (OR, 0.41; 95% CI: 0.23-0.73). Aspirin has protective effects on people with chronic liver disease (OR, 0.46; 95% CI: 0.31-0.67) and on the general population (OR, 0.65; 95% CI: 0.54-0.79). In addition, confounding factors have an important impact on the results of aspirin prevention of liver cancer before (OR, 0.28; 95% CI: 0.06-1.27) and after (OR, 0.58; 95% CI: 0.47-0.71) adjustment. Further studies have shown that those in the long duration group do not experience better effects in preventing HCC (OR, 0.62 vs. 0.63). A further meta-analysis of 3 articles showed that the use of aspirin did not increase the risk of bleeding in patients with HCC (OR, 1.19; 95% CI: 0.87-1.64). CONCLUSION Our meta-analysis shows that the use of aspirin is associated with a lower risk of liver cancer.

The Performance of Serum Alpha-Fetoprotein for Detecting Early-Stage Hepatocellular Carcinoma Is Influenced by Antiviral Therapy and Serum Aspartate Aminotransferase: A Study in a Large Cohort of Hepatitis B Virus-Infected Patients. Viruses 2022; 14:v14081669. [PMID: 36016291 PMCID: PMC9416230 DOI: 10.3390/v14081669] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Revised: 06/25/2022] [Accepted: 07/14/2022] [Indexed: 11/17/2022] [Imported: 09/25/2023] Open
Abstract
Background and aims: Factors associated with abnormally elevated alpha-fetoprotein (AFP) in hepatitis B virus (HBV)-infected patients remain to be studied. We aimed to identify factors associated with elevated serum AFP in patients with non-hepatocellular carcinoma (HCC) and early-stage HCC and their influences on the performance of AFP for detecting early-stage HCC. Methods: This multicenter, retrospective study was conducted in 4401 patients with chronic HBV infection, including 3680 patients with non-HCC and 721 patients with early-stage HCC. Factors associated with elevated AFP were analyzed. Diagnostic performance of AFP for early-stage HCC were compared among groups through area under the receiver operating characteristic curve (AUC), sensitivity, and specificity. Results: When analyzed by multivariate logistic regression, antiviral therapy was negatively associated with elevated AFP, while hepatitis B e antigen (HBeAg) and aspartate aminotransferase (AST) > 1× upper limit of normal (ULN) were positively associated with elevated AFP both in patients with non-HCC and early-stage HCC (all p < 0.05). The AUCs of AFP for detecting early-stage HCC in patients with antiviral therapy, HBV DNA (−), alanine aminotransferase (ALT) ≤ 1× ULN, and AST ≤ 1× ULN were significantly higher compared to those in non-antiviral therapy, HBV DNA (+), ALT > 1× ULN, and AST > 1× ULN groups, respectively. When categorizing patients into AST ≤ 1× ULN and > 1× ULN, AFP achieved the highest AUCs in patients with AST ≤ 1× ULN regardless of antiviral treatment (AUCs = 0.813 and 0.806, respectively). Furthermore, there were considerable differences in the cut-off values of AFP in detecting early-stage HCC in different subgroups when applying similar sensitivity and specificity. Conclusions: Antiviral therapy and serum AST might be used to help judge and select the specific cut-off values of serum AFP for HCC surveillance in different at-risk populations.

Abstract
BACKGROUND Abatacept is a selective T-cell costimulation modulator approved for the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, and psoriatic arthritis. Reports were recently published on hepatitis B virus reactivation (HBVr) in patients who were treated with abatacept. However, the literature is limited to case reports and series, and no study has investigated the relationship between HBVr and abatacept using extensive population-based databases. METHODS Using the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database, we collected all cases of HBVr between Jan 1, 2006 and June 30, 2021, for abatacept and other drugs. Disproportionality was analysed using the reporting odds ratio (ROR), which was considered significant when the lower limit of the 95% CI was >1. We also conducted a confirmatory analysis in the European pharmacovigilance database, EudraVigilance. FINDINGS During the study period, 77,669 adverse cases were reported for abatacept use. There were 2889 reports of HBVr with any drug during this period, of which 55 were reported with abatacept. The ROR for HBVr with abatacept was significantly elevated at 4·80 (95% CI 3·68-6·27). All 55 cases of HBVr with abatacept were reported as serious adverse events. Of them, six individuals were hospitalised and four died. Among 832 reports of HBVr with any drug in EudraVigilance, 43 were reported with abatacept; the ROR was 8·99 (95% CI 6·61-12·23). INTERPRETATION We identified a positive signal between abatacept exposure and HBVr. Future prospective studies should further confirm the relationship and provide evidence to develop strategies involving pre-treatment screening, monitoring, and utilisation of antiviral prophylaxis when using abatacept in patients with rheumatic diseases.

Abstract
BACKGROUND The use of statins is a potential protective factor against the development of hepatocellular carcinoma. Therefore, we conducted a meta-analysis to evaluate the contribution of statins to the risk of hepatocellular carcinoma. METHODS We searched for PubMed and EMBASE through January 2021. RESULTS Thirty-two studies (eighteen cohort, eleven case-control, and three randomized controlled trials) reporting 56,838 cases of hepatocellular carcinoma in 4,963,518 persons were included. Statin users were less likely to develop hepatocellular carcinoma than nonusers (adjusted odds ratio, 0.58; 95% CI: 0.51-0.67). Stratified analysis showed that statins reduced the risk of hepatocellular carcinoma in Asian and Western populations (odds ratio, 0.54 vs. 0.60). Besides, statins have protective effects against hepatocellular carcinoma after hepatitis B virus (odds ratio, 0.44; 95% CI: 0.22-0.85) and hepatitis C virus infections (odds ratio, 0.53; 95% CI: 0.49-0.57). Statins have protective effects on people with chronic liver disease (odds ratio, 0.52; 95% CI: 0.40-0.68) and on the general population (odds ratio, 0.60; 95% CI: 0.50-0.72). Lipophilic statins can prevent hepatocellular carcinoma (odds ratio, 0.51, 95% CI: 0.46-0.57), while hydrophilic statins cannot (odds ratio, 0.77, 95% CI: 0.58-1.02). The single-drug analyses showed that simvastatin (odds ratio, 0.53, 95% CI: 0.48-0.59), atorvastatin (odds ratio, 0.54, 95% CI: 0.45-0.64), rosuvastatin (odds ratio, 0.55, 95% CI: 0.37-0.83), lovastatin (odds ratio, 0.30, 95% CI: 0.15-0.62), and pitavastatin (odds ratio, 0.36, 95% CI: 0.17-0.75) had significant benefits. Further studies have shown that those in the high-dose group experienced better effects in preventing hepatocellular carcinoma (adjusted hazard ratio, 0.38 vs. 0.55). Further research found that the combined use of aspirin did not increase the chemoprevention effect of liver cancer (odds ratio, 0.57; 95% CI: 0.40-0.81). In addition, the preventive effect of statins improved with the extension of follow-up time (odds ratio, 0.54 vs. 0.65). CONCLUSION Our meta-analysis shows that the use of statins is associated with a lower risk of liver cancer.

DNA methylation and single-nucleotide polymorphisms in DDX58 are associated with hand, foot and mouth disease caused by enterovirus 71. PLoS Negl Trop Dis 2022; 16:e0010090. [PMID: 35041675 PMCID: PMC8765647 DOI: 10.1371/journal.pntd.0010090] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 12/14/2021] [Indexed: 12/28/2022] [Imported: 09/25/2023] Open
Abstract
BACKGROUND This research aimed to explore the association between the RIG-I-like receptor (RIG-I and MDA5 encoded by DDX58 and IFIH1, respectively) pathways and the risk or severity of hand, foot, and mouth disease caused by enterovirus 71 (EV71-HFMD). In this context, we explored the influence of gene methylation and polymorphism on EV71-HFMD. METHODOLOGY/PRINCIPAL FINDINGS 60 healthy controls and 120 EV71-HFMD patients, including 60 mild EV71-HFMD and 60 severe EV71-HFMD patients, were enrolled. First, MiSeq was performed to explore the methylation of CpG islands in the DDX58 and IFIH1 promoter regions. Then, DDX58 and IFIH1 expression were detected in PBMCs using RT-qPCR. Finally, imLDR was used to detect DDX58 and IFIH1 single-nucleotide polymorphism (SNP) genotypes. Severe EV71-HFMD patients exhibited higher DDX58 promoter methylation levels than healthy controls and mild EV71-HFMD patients. DDX58 promoter methylation was significantly associated with severe HFMD, sex, vomiting, high fever, neutrophil abundance, and lymphocyte abundance. DDX58 expression levels were significantly lower in mild patients than in healthy controls and lower in severe patients than in mild patients. Binary logistic regression analysis revealed statistically significant differences in the genotype frequencies of DDX58 rs3739674 between the mild and severe groups. GeneMANIA revealed that 19 proteins displayed correlations with DDX58, including DHX58, HERC5, MAVS, RAI14, WRNIP1 and ISG15, and 19 proteins displayed correlations with IFIH1, including TKFC, IDE, MAVS, DHX58, NLRC5, TSPAN6, USP3 and DDX58. CONCLUSIONS/SIGNIFICANCE DDX58 expression and promoter methylation were associated with EV71 infection progression, especially in severe EV71-HFMD patients. The effect of DDX58 in EV71-HFMD is worth further attention.

Abstract
BACKGROUND & AIMS The effectiveness and safety of peginterferon alpha (peg-IFN-α) monotherapy in inactive hepatitis B virus (HBV) carriers (IHCs) have not been fully evaluated. METHODS This observational study prospectively enrolled 298 IHCs in China from 2015 to 2019. Participants were given the right to choose to either receive peg-IFN-α monotherapy (treatment group, n = 142) or be monitored without treatment (control group, n = 156) according to their wishes. The scheduled treatment duration was 48 weeks. All participants were followed up to 72 weeks. The main efficacy endpoint was hepatitis B surface antigen (HBsAg) clearance at 72 weeks. RESULTS Baseline characteristics were similar between both groups. At 72 weeks, intention-to-treat analysis showed that the rates of HBsAg clearance and seroconversion of the treatment group were 47.9% (68/142) and 36.6% (52/142), respectively, which were significantly higher than the HBsAg clearance rate of 1.9% (3/156) and the seroconversion rate of 0.6% (1/156) in the control group (both P < .001). Baseline HBV DNA < 20 IU/mL, lower HBsAg levels at baseline, 12 and 24 weeks, alanine aminotransferase elevation at 12 weeks, and greater HBsAg reduction from baseline to 12 and 24 weeks were independent predictors of HBsAg clearance. Generally, the therapy was well tolerated. Only five participants discontinued therapy as a result of peg-IFNα-related adverse events. CONCLUSIONS Peg-IFN-α monotherapy results in high rates of HBsAg clearance and seroconversion and the treatment is safe for IHCs.

Abstract
Angiopoietin like 4 (ANGPTL4) has been proved to play an important role in lipid and glucose metabolism disorders and related cardiovascular diseases, but its role in the formation of cirrhosis still needs to be further explored. Therefore, the aim of this study was to investigate the role of ANGPTL4 in the development of liver cirrhosis and its mechanism, as well as its effect on Kupffer cell polarization and hepatic stellate cell activation. The ELISA and RT-qPCR assay were used to detect the content of ANGPTL4 in serum and mRNA expression in cells and tissues respectively. The expression of ANGPTL4, Arg1 and Mrc2 in Kupffer cells was measured by Western blot. The percentage of CD163+ and CD206+ cells was measured by flow cytometry. Mice cirrhosis model was established, and the expression of ANGPTL4 was interfered by injecting sh-ANGPTL4 lentiviral vector into caudal vein. The results revealed that ANGPTL4 was significantly up-regulated in liver cirrhosis patients and HBV induced liver injury cell models. Further studies found that interference with ANGPTL4 regulated CD163 and inhibited the polarization and proinflammatory effects of KCs,as well as inhibited the activation of hepatic stellate cells (HSCs) and fibrosis. More importantly, Interference with ANGPTL4 inhibits the progression of liver cirrhosis in mice. What's more, TLR4/NF-κB pathway was involved in the molecular mechanism of ANGPTL4 on Kupffer cells and hepatic stellate cells. It is suggested that the mechanism of sh-ANGPTL4 suppressing the polarization of KCs and the activation of hepatic stellate cells (HSCs) is to regulate the TLR4/NF-κB signaling pathways.

Abstract
IMPORTANCE Atezolizumab plus bevacizumab as a first-line therapy for patients with unresectable or metastatic hepatocellular carcinoma has been shown to improve overall and progression-free survival compared with standard sorafenib treatment. However, because of the high cost of atezolizumab plus bevacizumab, assessment of its value by considering both efficacy and cost is needed. OBJECTIVE To evaluate the cost-effectiveness of atezolizumab plus bevacizumab vs sorafenib for patients with unresectable or metastatic hepatocellular carcinoma from a US payer perspective. DESIGN, SETTING, AND PARTICIPANTS This economic evaluation was performed from June through September 2020, with a 6-year investment time period. Hypothetical patients were male and female adults 18 years or older who had a diagnosis of locally advanced metastatic or unresectable hepatocellular carcinoma confirmed by histologic or clinical features. MAIN OUTCOMES AND MEASURES Health care costs (adjusted to 2020 US dollars), life-years, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratio (ICER) of atezolizumab plus bevacizumab vs sorafenib were examined using a partitioned survival model. One-way deterministic and probabilistic sensitivity analyses were used to examine model uncertainty. The model was also used to estimate price reductions of atezolizumab plus bevacizumab that would achieve more favorable cost-effectiveness. RESULTS In the base case analysis of a hypothetical sample of 424 patients, atezolizumab plus bevacizumab was associated with an increase of 0.623 life-years (1.840 vs 1.218 life-years) and 0.484 QALYs (1.412 vs 0.928 QALYs) and with an incremental cost of $156 210 per patient compared with sorafenib. The ICER was $322 500 per QALY (5th to 95th percentile, $149 364-$683 744 per QALY), with 0.6% and 5.1% chance of being cost-effective at willingness-to-pay thresholds of $100 000 and $150 000 per QALY, respectively. The ICER never decreased below $150 000 per QALY in the 1-way sensitivity analyses. To achieve more favorable cost-effectiveness under the thresholds of $150 000 to $100 000 per QALY, the prices of atezolizumab and bevacizumab would need to be reduced by 37% to 47%. CONCLUSIONS AND RELEVANCE In this economic evaluation, atezolizumab plus bevacizumab was associated with clinical benefit but was not cost-effective compared with sorafenib for first-line treatment of unresectable or metastatic hepatocellular carcinoma from a US payer perspective. A substantial reduction in price for atezolizumab plus bevacizumab would be needed to achieve favorable cost-effectiveness for this new therapy.

Abstract
BACKGROUND AND AIM Globally, China has the highest chronic hepatitis C (CHC) burden, but its real-world direct-acting antiviral (DAA) data are limited. Our aim is to investigate the real-world outcome of China Food and Drug Administration-approved DAA therapies across mainland China including those with genotype (GT) 3. METHODS The REAL-C is a multinational real-world interferon-free DAA-treated CHC registry of several mainland China and other Asian centers. We evaluated the sustained virological response rate 12 weeks after end of treatment (SVR12), adverse events, and treatment effect on liver function and fibrosis (fibrosis-4 index). RESULTS We analyzed 859 DAA-treated CHC patients (6/1/2017-5/30/2019) from 12 mainland China centers (three municipalities and nine provinces): median age 52, 49.9% male, 33.1% cirrhosis, 95% treatment naïve, and 2.5% HBsAg+ . The most common GT was GT1b (523, 62.2%), followed by GT2a (156, 18.5%), GT3b (74, 8.8%), GT3a (41, 4.9%), and GT6 (37, 4.4%). SVR12 rates were 98.0% overall (95% confidence interval 96.9-98.8%), 98.1% for GT1b, 96.8% GT2a, 100% GT3a, 97.3% GT3b, and 100% GT6. Baseline cirrhosis and male sex but not prior treatment history, renal dysfunction, age, and GTs were associated with SVR12. For both cirrhotic and non-cirrhotic patients, there were significant improvement in liver function tests, alpha fetoprotein, and fibrosis-4 index with SVR12. Serious adverse events were rare (1.1%) with only nine patients discontinuing therapy prematurely and anemia being the most common adverse event (13.1%, mostly with ribavirin). CONCLUSIONS In real-world Chinese patients with diverse GTs, Chinese Food and Drug Administration-approved interferon-free DAAs were well tolerated, provided high cure rates (98.0% overall) including GT3a/3b, and led to improvement of liver function.

Abstract
Severe hand, foot, and mouth disease (HFMD) caused by enterovirus 71 (EV71) infection is associated with high mortality and disability. DC-SIGN, a receptor for EV71, is widely distributed in dendritic cells and may influence the severity of HFMD caused by EV71 infection. This observational study attempts to explore whether single-nucleotide polymorphisms (SNPs) in DC-SIGN are related to the severity of EV71-associated HFMD. Based on linkage disequilibrium and functional predictions, two DC-SIGN SNPs were selected and tested to explore their potential association with the severity of HFMD caused by EV71 infection. Two hundred sixteen Han Chinese children with HFMD caused by EV71 were enrolled to obtain clinical data, including the severity of HFMD, serum DC-SIGN levels, and DC-SIGN SNPs. We found a significant association between the rs7248637 polymorphism (A vs. G: OR = 0.644, 95% CI = 0.515-0.806) and the severity of HFMD caused by EV71 infection, as well as the rs4804800 polymorphism (A vs. G: OR = 1.539, 95% CI =1.229-1.928). These two DC-SIGN SNPs may have an effect on the severity of HFMD caused by EV71 infection.

Abstract
OBJECTIVES To explore the mechanisms of interferon-induced transmembrane protein 3 (IFITM3) in response to enterovirus-71-associated hand, foot and mouth disease (EV71-HFMD), in terms of DNA methylation, single-nucleotide polymorphism (SNP) genotype and gene expression. METHODS In total, 120 patients with EV71-HFMD (60 with mild EV71-HFMD and 60 with severe EV71-HFMD) and 60 healthy controls were enrolled in this study. SNP genotype, IFITM3 promoter methylation and mRNA expression of peripheral blood mononuclear cells were examined using the improved multi-temperature ligase detection reaction, quantitative reverse transcriptase polymerase chain reaction and MiSeq, respectively. RESULTS The distribution of methylation in patients with EV71-HFMD was significantly lower compared with healthy controls, and the severe EV71-HFMD group showed the lowest frequency of IFITM3 promoter methylation. The average level of IFITM3 promoter CpG methylation was negatively correlated with IFITM3 mRNA expression, and hypermethylation of several specific CpG units contributed to IFITM3 downregulation. IFITM3 expression and promoter methylation correlated with EV71 infection progression, especially in the severe EV71-HFMD group. Compared with mild cases, genotype GG and the G allele of rs12252 were over-represented in patients with severe EV71-HFMD. CONCLUSIONS IFITM3 methylation status and SNP genotyping may help clinicians to choose the correct treatment strategy for patients with EV71-HFMD.

Abstract
BACKGROUND AND AIMS There are few studies on non-obese fatty liver disease, the aims of this study was to analyze its prevalence, popular trends, and associated and predictive factors, so as to provide reference for its prevention and treatment. METHODS Individuals with complete data of body mass index, sex, age, and abdominal ultrasound in Karamay Central Hospital from 2009 to 2016 were selected to analyze the prevalence and popular trends of non-obese fatty liver disease (body mass index <24 kg/m2), and associated and predictive factors. RESULTS Between 2009 and 2016, a total of 191,555 medical check-ups were included. The prevalence of non-obese fatty liver disease increased from 1.9% to 5.1% among general medical examinants (P<0.001), increased from 4.6% to 11.7% in non-obese individuals (P<0.001). Compared with the non-obese control group, the levels of age, body mass index, blood pressure, fasting blood glucose, triglycerides, total cholesterol and uric acid in the non-obese fatty liver group were higher (P<0. 05). Even among non-obese subjects, elevated body mass index was associated with a 0.63-fold increased risk for non-obese fatty liver disease (P<0.001, odds ratio=1.63, 95% confidence interval 1.54-1.72) for every one-unit increase in body mass index. The most common abnormal indicator of non-obese fatty liver disease was elevated triglycerides (44.2%), which was also the best predictor of non-obese fatty liver disease (area under the curve =0.795) in non-obese physical examinators. CONCLUSIONS The prevalence of non-obese fatty liver disease was high and increasing rapidly in Karamay. Triglycerides is the best predictor of non-obese fatty liver in non-obese physical examinators.

Abstract
Hand, foot, and mouth disease (HFMD) caused by enterovirus 71 (EV71) can lead to high morbidity and mortality, and genetic background plays an important role during the disease process. We investigated the association between the single-nucleotide polymorphism (SNP) rs2564978 of the CD55 gene and susceptibility to and severity of HFMD using the SNPs can multiple SNP typing methods. Soluble CD55 (sCD55) expression was significantly lower in the EV71 HFMD group than in the control group and lower in severe cases than in mild cases (P < .001). Moreover, CD55 rs2564978 (C vs T OR = 1.300, 95% CI, 1.120-1.509) was associated with the risk of EV71 infection, and genotype TC was related to the severity of the infection (TC vs TT OR = 4.523, 95% CI, 2.033-10.066). Our results suggest that sCD55 expression and the CD55 polymorphism rs2564978 may influence the susceptibility to and severity of EV71 infection.

Abstract
Introduction Severe hand, foot, and mouth disease (HFMD) may lead to serious complications, which cause child mortality during outbreaks. The aim of this study was to determine whether neutrophil-to-lymphocyte ratio (NLR) can predict death risk in severe HFMD. Methods Medical records for 664 severe HFMD patients were retrospectively examined, and NLR was calculated from blood counts. Youden’s index was calculated to determine the optimal NLR cutoff. Uni- and multivariate logistic regression were used to determine death risk factors associated with severe HFMD. Results An NLR cutoff value of 2.01 and 2.50 respectively predicted mortality among all 664 severe HFMD and 137 critical HFMD. Among all 664 patients, the multivariate model identified the following as independently associated with death risk: high fever (OR 3.342, 95% CI 1.736–6.432), EV71 infection (OR 3.200, 95% CI 1.529–6.698), fasting glucose (OR 37.343, 95% CI 18.616–74.909), and NLR (>2.01) (OR 2.142, 95% CI 1.125–4.079). Among 137 critical HFMD, EV71 infection (OR 3.441, 95% CI 1.132–10.462), fasting glucose (OR 14.173, 95% CI 4.920–40.827), and NLR (>2.50) (OR 4.166, 95% CI 1.570–11.051) were associated with death risk. Conclusion In conclusion, NLR (>2.01) in severe HFMD and NLR (>2.50) in critical HFMD patients may be associated with increased death risk.

BACKGROUND A novel coronavirus, SARS-CoV-2, was identified in December 2019, when the first cases were reported in Wuhan, China. The once-localized outbreak has since been declared a pandemic. As of April 24, 2020, there have been 2.7 million confirmed cases and nearly 200,000 deaths. Early warning systems using new technologies should be established to prevent or mitigate such events in the future. OBJECTIVE This study aimed to explore the possibility of detecting the SARS-CoV-2 outbreak in 2019 using social media. METHODS WeChat Index is a data service that shows how frequently a specific keyword appears in posts, subscriptions, and search over the last 90 days on WeChat, the most popular Chinese social media app. We plotted daily WeChat Index results for keywords related to SARS-CoV-2 from November 17, 2019, to February 14, 2020. RESULTS WeChat Index hits for "Feidian" (which means severe acute respiratory syndrome in Chinese) stayed at low levels until 16 days ahead of the local authority's outbreak announcement on December 31, 2019, when the index increased significantly. The WeChat Index values persisted at relatively high levels from December 15 to 29, 2019, and rose rapidly on December 30, 2019, the day before the announcement. The WeChat Index hits also spiked for the keywords "SARS," "coronavirus," "novel coronavirus," "shortness of breath," "dyspnea," and "diarrhea," but these terms were not as meaningful for the early detection of the outbreak as the term "Feidian". CONCLUSIONS By using retrospective infoveillance data from the WeChat Index, the SARS-CoV-2 outbreak in December 2019 could have been detected about two weeks before the outbreak announcement. WeChat may offer a new approach for the early detection of disease outbreaks.

Facial and bilateral lower extremity edema due to drug-drug interactions in a patient with hepatitis C virus infection and benign prostate hypertrophy: A case report. World J Clin Cases 2020; 8:3372-3376. [PMID: 32874995 PMCID: PMC7441249 DOI: 10.12998/wjcc.v8.i15.3372] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/07/2020] [Accepted: 07/16/2020] [Indexed: 02/05/2023] [Imported: 09/25/2023] Open
Abstract
BACKGROUND New direct-acting antivirals (DAAs)-based anti-hepatitis C virus (HCV) therapies are highly effective in patients with HCV infection. However, safety data are lacking regarding HCV treatment with DAAs and drugs for comorbidities.
CASE SUMMARY Herein, we reported a case of HCV-infection in a 46-year-old man with benign prostatic hypertrophy. The patient received sofosbuvir/velpatasvir as well as methadone maintenance therapy for drug abuse. The viral load became negative at week 1 post treatment. He developed facial and bilateral lower extremity edema 48 h after starting receiving tamsulosin. Edema disappeared 10 d after treatment with oral furosemide and spironolactone.
CONCLUSION In conclusion, this is the first case of an acute edema in the course of treatment with new DAAs, methadone and tamsulosin. These agents are useful in clinical management of patients with HCV infection, particularly in men with benign prostatic hypertrophy. Clinicians should be aware of potential drug-drug interactions in this subset of patients.
