[PMID: 37099248 DOI: 10.1007/s12072-023-10528-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 03/18/2023] [Indexed: 04/27/2023]
Abstract
BACKGROUND The aim of this study was to demonstrate how tenofovir alafenamide (TAF) and other hepatitis B treatment drugs differentially impact lipid profiles in chronic hepatitis B patients. METHODS We searched PubMed, Ovid MEDLINE, EMBASE, and the Cochrane Library to identify studies on the changes in cholesterol level in hepatitis B patients who underwent TAF therapy. The changes in lipid profiles (e.g., HDL-c, LDL-c, total cholesterol [TC], and triglyceride [TG]) were compared between the TAF treatment group and the baseline, other nucleoside analogs (NAs), and tenofovir disoproxil fumarate (TDF)-only treatment groups. In addition, risk factors for worsening cholesterol level when treated with TAF were examined. RESULTS Twelve studies involving 6,127 patients were selected. After 6 months of TAF treatment, LDL-c, TC, and TG were increased by 5.69 mg/dL, 7.89 mg/dL, and 9.25 mg/dL, respectively, from the baseline level. In particular, with the treatment of TAF, levels of LDL, TC, and TG rose by 8.71 mg/dL, 18.34 mg/dL, and 13.68 mg/dL, respectively, showing a greater deterioration of cholesterol when the TAF treatment was implemented compared to other NAs (e.g., TDF or entecavir). When TAF was compared to TDF, LDL-c, TC, and TG worsened with a mean difference of 14.52 mg/dL, 23.72 mg/dL, and 14.25 mg/dL, respectively. As a result of a meta-regression analysis, risk factors for worsening lipid profiles were found to be treatment-experienced, previous diabetes, and hypertension. CONCLUSIONS TAF continues to worsen lipid profiles including LDL-c, TC, and TG after 6 months of use compared to the other NAs.

Abstract
Elaboration of carotid atherosclerosis in the setting of hepatitis B virus (HBV) infection should emphasize the significance of extrahepatic manifestations of the infection pathogenesis. Diverse processes comprise the pathoevolution of HBV infection, rendering it a multi-systemic disease in its essence. Our work not only exemplified atherosclerosis as an often-underestimated contributor to the severity of HBV infection but has also highlighted the bidirectional relationship between the two. Therefore, it is suggested that HBV-induced inflammation is one of the root causes of atherosclerosis, which in turn has a consequent effect on the severity of the chronic infection disease state, creating a vicious cycle. Additionally, we coupled prior data with the current concepts of HBV infection to postulate intriguing perspectives and theories.

Rapid Decline of Serum Proprotein Convertase Subtilisin/Kexin 9 (PCSK9) in Non-Cirrhotic Patients with Chronic Hepatitis C Infection Receiving Direct-Acting Antiviral Therapy. J Clin Med 2021; 10:1621. [PMID: 33920491 PMCID: PMC8069657 DOI: 10.3390/jcm10081621] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 03/30/2021] [Accepted: 04/06/2021] [Indexed: 02/06/2023] Open
Abstract
Direct-acting antivirals (DAAs) efficiently eradicate the hepatitis C virus (HCV). Low-density lipoprotein (LDL) levels increase rapidly upon DAA treatment. Proprotein convertase subtilisin/kexin 9 (PCSK9) induces degradation of the hepatic LDL receptor and thereby elevates serum LDL. The aim of this study was to determine serum PCSK9 concentrations during and after DAA therapy to identify associations with LDL levels. Serum PCSK9 was increased in 82 chronic HCV-infected patients compared to 55 patients not infected with HCV. Serum PCSK9 was low in HCV patients with liver cirrhosis, but patients with HCV-induced liver cirrhosis still exhibited higher serum PCSK9 than patients with non-viral liver cirrhosis. Serum PCSK9 correlated with measures of liver injury and inflammation in cirrhotic HCV patients. In patients without liver cirrhosis, a positive association of serum PCSK9 with viral load existed. Serum PCSK9 was not different between viral genotypes. Serum PCSK9 did not correlate with LDL levels in HCV patients irrespective of cirrhotic status. Serum PCSK9 was reduced, and LDL was increased at four weeks after DAA therapy start in non-cirrhotic HCV patients. Serum PCSK9 and LDL did not change upon DAA treatment in the cirrhotic group. The rapid decline of PCSK9 after the start of DAA therapy in conjunction with raised LDL levels in non-cirrhotic HCV patients shows that these changes are not functionally related.

Abstract
BACKGROUND Many people infected with hepatitis C virus have comorbidities, including hypercholesterolemia, that are treated with statins. In this study, we evaluated the drug-drug interaction potential of the hepatitis C virus inhibitors elbasvir (EBR) and grazoprevir (GZR) with statins. Pitavastatin, rosuvastatin, pravastatin, and atorvastatin are substrates of organic anion-transporting polypeptide 1B, whereas rosuvastatin and atorvastatin are also breast cancer resistance protein substrates. METHODS Three open-label, phase I clinical trials in healthy adults were conducted with multiple daily doses of oral GZR or EBR/GZR and single oral doses of statins. Trial 1: GZR 200 mg plus pitavastatin 10 mg. Trial 2: Part 1, GZR 200 mg plus rosuvastatin 10 mg, then EBR 50 mg/GZR 200 mg plus rosuvastatin 10 mg; Part 2, EBR 50 mg/GZR 200 mg plus pravastatin 40 mg. Trial 3: EBR 50 mg/GZR 200 mg plus atorvastatin 10 mg. RESULTS Neither GZR nor EBR pharmacokinetics were meaningfully affected by statins. Coadministration of EBR/GZR did not result in clinically relevant changes in the exposure of pitavastatin or pravastatin. However, EBR/GZR increased exposure to rosuvastatin (126%) and atorvastatin (94%). Coadministration of statins plus GZR or EBR/GZR was generally well tolerated. CONCLUSIONS Although statins do not appreciably affect EBR or GZR pharmacokinetics, EBR/GZR can impact the pharmacokinetics of certain statins, likely via inhibition of breast cancer resistance protein but not organic anion-transporting polypeptide 1B. Coadministration of EBR/GZR with pitavastatin or pravastatin does not require adjustment of either dose of statin, whereas the dose of rosuvastatin and atorvastatin should be decreased when coadministered with EBR/GZR.

Abstract
Chronic hepatitis B virus (HBV) infection is a major public health challenge on the global scale. Affecting hundreds of millions worldwide, HBV is a leading risk factor for hepatocellular carcinoma (HCC). Clinical outcomes from chronic HBV infection are varied and appear to be influenced by a complex and dysregulated host immune response. In turn, much attention has been given to the immunologic response to HBV in an effort to identify host factors that lead to the development of HCC. However, the role of nonimmunologic host factors, such as chronic stress, in HBV-related HCC is poorly defined. Indeed, a growing appreciation for the effects of stress on chronic liver diseases raises the question of its role in chronic HBV infection. In this light, the present review will untangle the roles of key host factors in HBV-related HCC with an emphasis on chronic stress as a viable contributor. First discussed is the interplay of stress, inflammation and chronic liver disease. The host immune response's role as a driver of HBV-related HCC is then reviewed, allowing for a close exploration of the effects of stress on immune function in chronic hepatitis B and as a potential risk factor for HBV-related HCC.

Abstract
Aging, as a physiological process mediated by numerous regulatory pathways and transcription factors, is manifested by continuous progressive functional decline and increasing risk of chronic diseases. There is an increasing interest to identify pharmacological agents for treatment and prevention of age-related disease in humans. Animal models play an important role in identification and testing of anti-aging compounds; this step is crucial before the drug will enter human clinical trial or will be introduced to human medicine. One of the main goals of animal studies is better understanding of mechanistic targets, therapeutic implications and side-effects of the drug, which may be later translated into humans. In this chapter, we summarized the effects of different drugs reported to extend the lifespan in model organisms from round worms to rodents. Resveratrol, rapamycin, metformin and aspirin, showing effectiveness in model organism life- and healthspan extension mainly target the master regulators of aging such as mTOR, FOXO and PGC1α, affecting autophagy, inflammation and oxidative stress. In humans, these drugs were demonstrated to reduce inflammation, prevent CVD, and slow down the functional decline in certain organs. Additionally, potential anti-aging pharmacologic agents inhibit cancerogenesis, interfering with certain aspects of cell metabolism, proliferation, angioneogenesis and apoptosis.

Abstract
Background Recent studies have shown benefits of statins in patients with liver cirrhosis. However, it is still unknown if statins have a beneficial effect on the mortality of cirrhotic patients with bacterial infections. Methods The Taiwan National Health Insurance Database was searched, and 816 cirrhotic patients receiving statins with bacterial infections hospitalized between January 1, 2010 and December 31, 2013 were included in the study. A one-to-four propensity score matching was performed to select a comparison group based on age, sex, and comorbid disorders. Results The overall 30-day mortalities in statin and non-statin group were 5.3% and 9.8%, respectively (P = 0.001). After Cox regression modeling adjusting for age, sex, and comorbid disorders, the hazard ratio (HR) of statin use on 30-day mortality was 0.52 (95% confidence interval [CI]: 0.38–0.72, P<0.001). In subgroup analysis, the 30-day mortality effect of statin use was more pronounced in patients with pneumonia (HR = 0.34; 95% CI: 0.19–0.59; P<0.001) and bacteremia (HR = 0.55; 95% CI: 0.35–0.85; P = 0.008). Atovastatin (HR = 0.59; 95% CI: 0.37–0.93) and rosuvastatin (HR = 0.59; 95% CI: 0.36–0.98) were associated with a decreased 30-day mortality risk compared to patients not taking statins. Conclusions Statin use decreases the 30-day mortality of cirrhotic patients with bacteremia and pneumonia.

Abstract
Background Liver cirrhosis is an uncommon but not rare side effect of amiodarone-induced hepatotoxicity. Patients with hepatitis B virus and hepatitis C virus infections are at a high risk for developing liver cirrhosis. However, the relationship between this treatment and risk of liver cirrhosis in high-risk chronic hepatitis B and chronic hepatitis C patients is unknown. Patients and methods The present study identified amiodarone users (N=8,081) from the Taiwan National Health Insurance Research Database from 1997 through 2013. A total of 32,324 subjects with age, comorbidities, gender, and index date-matched non-amiodarone users were selected as controls (non-amiodarone cohort). The incidences of cumulative liver cirrhosis were compared between cohorts. Stratified Cox’s regression hazard models were used to assess possible comorbidity-attributable risks for liver cirrhosis. Results The amiodarone cohort had a nonsignificant risk of liver cirrhosis compared with the non-amiodarone cohort, with a HR of 1.17 (95% CI: 0.93–1.47; P=0.1723). Patients with specific comorbid diseases, including type 2 diabetes mellitus, chronic hepatitis B, chronic hepatitis C, and heart failure, were probably at a high risk of developing liver cirrhosis. The use of statins was associated with a significant 42% reduction in the risk of liver cirrhosis. Conclusion Patients in the amiodarone cohort had no excess risk of liver cirrhosis compared with patients in the non-amiodarone cohort. Long-term surveillance for liver toxicity in high-risk patients with amiodarone treatment is suggested.

Abstract
Statins are commonly use for the management of dyslipidemia, worldwide. Various studies have demonstrated that statins offer significant reduction in the risk of cardiovascular morbidity and mortality. However, this class of drugs has been implicated in potential liver toxicity, thus has been considered as a 'forbidden-drug' in patients with increased liver enzymes. Areas covered: Studies have shown that statins might offer clinical benefits in the setting of viral hepatitis, progression of cirrhosis, and hepatocellular carcinoma. More importantly, this class of drugs was shown to ameliorate liver histological (in both imaging and biopsy studies) and functional alterations in patients with non-alcoholic fatty liver disease or non-alcoholic steatohepatitis. In addition, two large survival studies have demonstrated reduction in the risk for cardiovascular events with statin use in patients with elevated transaminase levels at baseline. Expert commentary: These benefits were of greater extent compared with patients with normal liver function tests at baseline. However, current international guidelines seem to neglect these findings and are not including statins in the management algorithm of patients with non-alcoholic fatty liver disease or steatohepatitis. Future randomized studies providing biopsy-proven benefits will establish the use of statins in the prevention of cardiovascular events and therapeutic algorithm of these patients.

Abstract
Clarivate Analytics's Web of Science (WoS) is the world's leading scientific citation search and analytical information platform. It is used as both a research tool supporting a broad array of scientific tasks across diverse knowledge domains as well as a dataset for large-scale data-intensive studies. WoS has been used in thousands of published academic studies over the past 20 years. It is also the most enduring commercial legacy of Eugene Garfield. Despite the central position WoS holds in contemporary research, the quantitative impact of WoS has not been previously examined by rigorous scientific studies. To better understand how this key piece of Eugene Garfield's heritage has contributed to science, we investigated the ways in which WoS (and associated products and features) is mentioned in a sample of 19,478 English-language research and review papers published between 1997 and 2017, as indexed in WoS databases. We offered descriptive analyses of the distribution of the papers across countries, institutions and knowledge domains. We also used natural language processingtechniques to identify the verbs and nouns in the abstracts of these papers that are grammatically connected to WoS-related phrases. This is the first study to empirically investigate the documentation of the use of the WoS platform in published academic papers in both scientometric and linguistic terms.
