Abstract
Liver diseases after kidney transplantation range from mild biochemical abnormalities to severe hepatitis or cirrhosis. The causes are diverse and mainly associated with hepatotropic viruses, drug toxicity and metabolic disorders. Over the past decade, the aetiology of liver disease in kidney recipients has changed significantly. These relates to the use of direct-acting antiviral agents against hepatitis C virus, the increasing availability of vaccination against hepatitis B and a better understanding of drug-induced hepatotoxicity. In addition, the emergence of the severe acute respiratory syndrome coronavirus 2 pandemic has brought new challenges to kidney recipients. This review aims to provide healthcare professionals with a comprehensive understanding of recent advances in the management of liver complications in kidney recipients and to enable them to make informed decisions regarding the risks and impact of liver disease in this population.

Cell Death Dis 2022; 8:380. [PMID: 36071041 PMCID: PMC9452542 DOI: 10.1038/s41420-022-01173-4] [Citation(s) in RCA: 33] [Impact Index Per Article: 16.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Revised: 08/23/2022] [Accepted: 08/26/2022] [Indexed: 11/09/2022]
Abstract
Hepatocellular death is a sensitive parameter for detecting acute liver injury (ALI) of toxic, viral, metabolic, and autoimmune origin. Ferroptosis has recently been implicated in carbon tetrachloride (CCl4)-induced ALI. However, the underpinning mechanism and mechanistic basis remain elusive. In this study, bicyclol, a proprietary hepatoprotectant in China, and ferroptosis-specific inhibitor ferrostatin-1 (Fer-1) were administered in CCl4-injured mice. A panel of ferroptosis-related markers, including mitochondria morphology, reactive oxygen species production, protein adducts in response to lipid peroxidation, and key modulators of ferroptotic process, was determined in vivo. Erastin-treated L-O2 hepatocytes were transfected with glutathione peroxidase 4 (GPx4) or nuclear factor erythroid 2-related factor 2 (Nrf2) siRNA to delineate the pathway of bicyclol against ferroptosis in vitro. As a result, CCl4 led to iron accumulation, excessive reactive oxygen species production, enhanced lipid peroxidation, and characteristic morphological changes in mitochondria, along with a decrease in GPx4 and xCT protein levels in ALI mice liver, all of which were generally observed in ferroptosis. The use of Fer-1 further corroborated that ferroptosis is responsible for liver damage. Bicyclol exerted its hepatoprotection by preventing the aforesaid ferroptotic process. Furthermore, bicyclol alleviated erastin-induced cellular inviability, destruction, and lipid peroxidation in vitro. Knockdown of GPx4 diminished these protective activities against perturbations associated with ferroptosis in L-O2 hepatocytes. Additionally, Nrf2 silencing drastically reduced GPx4 levels, and further impeded the medicinal effects of bicyclol. In summary, positively regulating Nrf2-GPx4 axis by bicyclol can prevent ferroptosis in CCl4-induced ALI in mice.

Abstract
INTRODUCTION In 2021, over 3,000 articles on Drug-Induced Liver Injury (DILI) were published, nearly doubling the annual number compared to 2011. This review selected DILI articles from 2021 we felt held the greatest interest and clinical relevance. AREAS COVERED A literature search was conducted using PubMed between 1 March 2021 and 28 February 2022. 86 articles were included. This review discusses new and established cases of hepatotoxins, including new FDA approvals and COVID-19 therapeutics. Developments in biomarkers and causality assessment methods are discussed. Updates from registries are also explored. EXPERT OPINION DILI diagnosis and prognostication remain challenging. Roussel Uclaf Causality Assessment Method (RUCAM) is the best option for determining causality and has been increasingly accepted by clinicians. Revised Electronic Causality Assessment Method (RECAM) may be more user-friendly and accurate but requires further validation. Quantitative systems pharmacology methods, such as DILIsym, are increasingly used to predict hepatotoxicity. Oncotherapeutic agents represent many newly approved and described causes of DILI. Such hepatotoxicity is deemed acceptable relative to the benefit these drugs offer. Drugs developed for non-life-threatening disorders may not show a favorable benefit-to-risk ratio and will be more difficult to approve. As the COVID-19 landscape evolves, its effect on DILI deserves further investigation.

Abstract
OBJECTIVES To compare the effect of berberine and bicyclol on patients with non-alcoholic fatty liver disease (NAFLD). METHODS Chinese non-alcoholic and non-viral hepatitis patients with a hepatic lipid content > 13% and non-alcoholic fatty liver disease activity score (NAS) ≥ 2 were treated with 500 mg berberine thrice daily, together with dietary modification (low-fat diet) and Tai Chi exercise for 4 months (BT cohort; n = 112), or 25 mg bicyclol thrice daily plus dietary modification and Tai Chi exercise for 4 months (CT cohort, n = 145), or dietary modification and Tai Chi exercise for 4 months (DT cohort, n = 128). RESULTS Patients in the BT and the CT cohorts had improved anthropometric measurements (weight, height, body mass index, and waist-to-hip ratio), biochemical parameters (blood sugar, lipid profile, and liver functions tests), liver/spleen computed tomography findings, and liver biopsy results after 4 months of intervention (p < 0.05 for all). Bicyclol decreased the NAS in the CT cohort to a significantly greater degree than berberine in the BT cohort (p < 0.0001, q = 3.879). Patients in the DT cohort had reduced body mass index and waist-to-hip ratio (p < 0.05 for both). During the 4-month intervention, patients in the BT cohort had abdominal distension, mild diarrhea, constipation, nausea, and dyspepsia; patients in the CT cohort had dizziness and abdominal distension. CONCLUSIONS Berberine or bicyclol plus dietary modification and Tai Chi exercise could control NAFLD without serious adverse effects. Dietary modification and Tai Chi exercise alone for 4 months are insufficient for the management of NAFLD. It is possible to reduce body weight by administering berberine or bicyclol.
