Stülb H, Bachmann M, Gonther S, Mühl H. Acetaminophen-Induced Liver Injury Exposes Murine IL-22 as Sex-Related Gene Product. Int J Mol Sci 2021; 22:10623. [PMID: 34638962 PMCID: PMC8509061 DOI: 10.3390/ijms221910623] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 09/24/2021] [Accepted: 09/27/2021] [Indexed: 12/13/2022] Open
Abstract
Gaining detailed knowledge about sex-related immunoregulation remains a crucial prerequisite for the development of adequate disease models and therapeutic strategies enabling personalized medicine. Here, the key parameter of the production of cytokines mediating disease resolution was investigated. Among these cytokines, STAT3-activating interleukin (IL)-22 is principally associated with recovery from tissue injury. By investigating paradigmatic acetaminophen-induced liver injury, we demonstrated that IL-22 expression is enhanced in female mice. Increased female IL-22 was confirmed at a cellular level using murine splenocytes stimulated by lipopolysaccharide or αCD3/CD28 to model innate or adaptive immunoactivation. Interestingly, testosterone or dihydrotestosterone reduced IL-22 production by female but not by male splenocytes. Mechanistic studies on PMA/PHA-stimulated T-cell-lymphoma EL-4 cells verified the capability of testosterone/dihydrotestosterone to reduce IL-22 production. Moreover, we demonstrated by chromatin immunoprecipitation that testosterone impairs binding of the aryl hydrocarbon receptor to xenobiotic responsive elements within the murine IL-22 promoter. Overall, female mice undergoing acute liver injury and cultured female splenocytes upon inflammatory activation display increased IL-22. This observation is likely related to the immunosuppressive effects of androgens in males. The data presented concur with more pronounced immunological alertness demonstrable in females, which may relate to the sex-specific course of some immunological disorders.

Protective effect of genistein pre-treatment on paraquat hepatotoxicity in rats. Toxicol Appl Pharmacol 2021; 426:115636. [PMID: 34214573 DOI: 10.1016/j.taap.2021.115636] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Revised: 06/22/2021] [Accepted: 06/25/2021] [Indexed: 12/21/2022]
Abstract
Paraquat (PQ), an herbicide widely used in agriculture, is considered a highly toxic compound. In hepatocytes, P-glycoprotein (P-gp/Abcb1) is a canalicular transporter involved in PQ extrusion from the cell. Previously, we demonstrated that genistein (GNT) induces P-gp in rat liver. In this study, the protective role of GNT pretreatment towards hepatic damage in a model of acute intoxication with PQ in rats, was investigated. Wistar rats were randomized in 4 groups: Control, GNT (5 mg/kg/day sc, 4 days), PQ (50 mg/kg/day ip, last day) and GNT+ PQ. Hepatic lipoperoxidation (LPO) was evaluated by the thiobarbituric acid reactive substances method. Hepatic levels of 4-hydroxynonenal protein adducts (4-HNEp-add) and glutathione-S-transferase alpha (GSTα) protein expression were evaluated by Western blotting. Hepatic glutathione levels and plasma levels of alanine transaminase (ALT) and aspartate transaminase (AST) were also measured. Biliary excretion of PQ was studied in vivo and in isolated perfused liver. PQ was quantified by HPLC. PQ significantly increased AST and ALT activities, malondialdehyde and 4-HNEp-add levels, whereby pretreatment with GNT ameliorated this effect. PQ biliary excretion remained unchanged after treatments in both experimental models. Hepatic GSTα expression was augmented in GNT group. GNT pretreatment increased hepatic glutathione levels in PQ + GNT group. These results agree with the lower content of 4-HNEp-adds in GNT + PQ group respect to PQ group. Unexpectedly, increased activity of P-gp did not enhance PQ biliary excretion. Thus, GNT protective mechanism is likely through the induction of GSTα which results in increased 4-HNE metabolism before formation of protein adducts.

Abstract
Valproate (VPA)-induced hepatotoxicity is a fatal adverse drug reaction,and children is a high-risk population. Our study aimed to explore whether key genetic polymorphisms of antioxidant pathway is associated with VPA-mediated AST elevation. We included 194 newly diagnosed epilepsy children (aged from 1 to 16 years old) and treated with VPA. These patients were divided into two groups: one group for AST is normal and another group is AST elevated. AST elevation occurred in 25.8% of patient treated with VPA. During VPA monotherapy, the maximum AST in patients of GSTP1 rs1695 with AA genotype was significantly higher than carrying G alleles (36.50 ±14.89 vs 32.88±10.69, P=0.003). Patients with AG+GG genotype of GSTP1 rs1695 had a reduced risk of elevated AST (adjusted OR=0.37, 95% CI: 0.16-0.84, P=0.017). There is a significant difference in the maximum AST value of CAT rs769217 genotype (P=0.011, P= 0.045, respectively). Children with CAT rs769217 CT genotype or CT+TT genotype have a lower risk of elevated AST (adjusted OR=0.30, 95% CI: 0.13-0.68, P=0.004 and adjusted OR=0.41, 95% CI:0.20-0.82,P=0.012, respectively). Children who with GSTP1 rs1695 G allele have a reduced risk of AST abnormalities. We conducted CAT rs769217 CC genotype is a risk factor for AST elevation in children.

Abstract
Osteoporosis is a systemic skeletal disease characterized by reduced bone mineral density (BMD), which results in an increased risk of fracture. Melandrium firmum (Siebold & Zucc.) Rohrbach (MFR), 'Wangbulryuhaeng' in Korean, is the dried aerial portion of Melandrii Herba Rohrbach, which is a member of the Caryophyllaceae family and has been used to treat several gynecological conditions as a traditional medicine. However, to the best of our knowledge, the effect of MFR on osteoclast differentiation and osteoporosis has not been assessed. To evaluate the effects of MFR on osteoclast differentiation, tartrate‑resistant acid phosphatase staining, actin ring formation and bone resorption assays were used. Additionally, receptor activator of nuclear factor‑κB ligand‑induced expression of nuclear factor of activated T cell, cytoplasmic 1 (NFATc1) and c‑Fos were measured using western blotting and reverse transcription‑PCR. The expression levels of osteoclast‑related genes were also examined. To further investigate the anti‑osteoporotic effects of MFR in vivo, an ovariectomized (OVX) rat model of menopausal osteoporosis was established. Subsequently, the femoral head was scanned using micro‑computed tomography. The results revealed that MFR suppressed osteoclast differentiation, formation and function. Specifically, MFR reduced the expression levels of osteoclast‑related genes by downregulating transcription factors, such as NFATc1 and c‑Fos. Consistent with the in vitro results, administration of MFR water extract to OVX rats reduced BMD loss, and reduced the expression levels of NFATc1 and cathepsin K in the femoral head. In conclusion, MFR may contribute to alleviate osteoporosis‑like symptoms. These results suggested that MFR may exhibit potential for the prevention and treatment of postmenopausal osteoporosis.

Coagulopathy, Bleeding Events, and Outcome According to Rotational Thromboelastometry in Patients With Acute Liver Injury/Failure. Hepatology 2021; 74:937-949.

Abstract
BACKGROUND AND AIMS Patients with acute liver injury or failure (ALI/ALF) experience bleeding complications uncommonly despite an abnormal hemostatic profile. Rotational thromboelastometry (ROTEM), which assesses clot formation in whole blood, was used to determine the nature of abnormal hemostasis and whether it contributes to bleeding events, illness severity, or survival. APPROACH AND RESULTS A total of 200 patients were recruited from sites of the ALF Study Group. Blood collected daily for up to 5 days was analyzed using ROTEM delta devices. Consistent with standard laboratory evidence of hypocoagulability (median international normalized ratio = 2.9 and platelet count = 144 × 109 /L), patients frequently exhibited ROTEM parameters outside the normal range (73% and 62% had abnormalities in clot formation from extrinsic and intrinsic clotting cascades, respectively); however, measures of clot stability were generally normal. Eighteen patients (9%) experienced bleeding events, in whom clot initiation, assembly, and firmness were more severely deranged than patients without bleeding. Abnormal ROTEM parameters were more frequently observed in patients with non-acetaminophen ALI/ALF than those with acetaminophen ALI/ALF (clot initiation [P < 0.001], assembly [P = 0.02], firmness at 10 minutes [P = 0.05], and maximal firmness [P = 0.06]). Patients with more severe systemic complications (high-grade hepatic encephalopathy and need for renal replacement therapy) also had a higher incidence of abnormal ROTEM parameters. Finally, more hypocoagulable ROTEM parameters (clot initiation (P = 0.005), stiffness at 10 minutes (P = 0.05), and maximal stiffness by fibrin assembly (P = 0.004)) were observed in patients who died or underwent liver transplantation than those who survived with their native liver. CONCLUSIONS In patients with ALI/ALF, abnormal ROTEM parameters are frequent and proportional to disease severity. Whether the increased bleeding risk associated with abnormal ROTEM indicates hemostatic failure or is a proxy for disease severity requires additional study.

Abstract
Nerol, a monoterpene is evident to possess diverse biological activities, including antioxidant, anti-microbial, anti-spasmodic, anthelmintic, and anti-arrhythmias. This study aims to evaluate its hepatoprotective effect against paracetamol-induced liver toxicity in a rat model. Five groups of rats (n = 7) were orally treated (once daily) with 0.05% tween 80 dissolved in 0.9% NaCl solution (vehicle), paracetamol 640 mg/kg (negative control), 50 mg/kg silymarin (positive control), or nerol (50 and 100 mg/kg) for 14 days, followed by the hepatotoxicity induction using paracetamol (PCM). The blood samples and livers of the animals were collected and subjected to biochemical and microscopical analysis. The histological findings suggest that paracetamol caused lymphocyte infiltration and marked necrosis, whereas maintenance of the normal hepatic structural was observed in group pre-treated with silymarin and nerol. The rats pre-treated with nerol significantly and dose-dependently reduced the hepatotoxic markers in animals. Nerol at 100 mg/kg significantly reversed the paracetamol-induced altered situations, including the liver enzymes, plasma proteins, antioxidant enzymes and serum bilirubin, lipid peroxidation (LPO) and cholesterol [e.g., total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c)] levels in animals. Taken together, nerol exerted significant hepatoprotective activity in rats in a dose-dependent manner. PCM-induced toxicity and nerol induced hepatoprotective effects based on expression of inflammatory and apoptosis factors will be future line of work for establishing the precise mechanism of action of nerol in Wistar albino rats.

Abstract
N-acetylcysteine (NAC) is an antidote to prevent acetaminophen (paracetamol-APAP)-induced acute liver injury (ALI). The 3-bag licensed 20.25 h standard regimen, and a 12 h modified regimen, are used to treat APAP overdose. This study evaluated the redox thiol response and APAP metabolites, in patients with a single APAP overdose treated with either the 20.25 h standard or 12 h modified regimen. We used liquid chromatography tandem mass spectrometry to quantify clinically important oxidative stress biomarkers and APAP metabolites in plasma samples from 45 patients who participated in a randomized controlled trial (SNAP trial). We investigated the time course response of plasma metabolites at predose, 12 h, and 20.25 h post-start of NAC infusion. The results showed that the 12 h modified regimen resulted in a significant elevation of plasma NAC and cysteine concentrations at 12 h post-infusion. We found no significant alteration in the metabolism of APAP, mitochondrial, amino acids, and other thiol biomarkers with the two regimens. We examined APAP and purine metabolism in overdose patients who developed ALI. We showed the major APAP-metabolites and xanthine were significantly higher in patients with ALI. These biomarkers correlated well with alanine aminotransferase activity at admission. Receiver operating characteristic analysis showed that at admission, plasma APAP-metabolites and xanthine concentrations were predictive for ALI. In conclusion, a significantly higher redox thiol response with the modified NAC regimen at 12 h postdose suggests this regimen may produce greater antioxidant efficacy. At baseline, plasma APAP and purine metabolites may be useful biomarkers for early prediction of APAP-induced ALI.

Abstract
Dictamnine (DIC), a typical furan-quinoline alkaloid, has a wide range of pharmacological and toxicological effects, such as anti-bacterial, antifungal, anti-cancer, and hepatoxicity. But the molecular mechanism of DIC-induced hepatoxicity in mice remains unclear. This study aimed to clarify the biotransformation patterns of DIC in vitro/in vivo and the relative molecular mechanism of DIC-induced hepatoxicity in mice. All metabolites of DIC were identified by comparing the blank and drug-containing urine, feces, plasma, and liver samples. The structure of epoxide intermediate derived from DIC was confirmed by trapping assay. Oxidative stress injury and inflammation have been confirmed to be involved in the toxicological process of DIC-induced hepatoxicity in mice by detecting the relative biochemical indexes. The results will help to develop a deeper understanding about the biotransformation patterns of DIC, structure of the epoxide intermediate, and the molecular mechanism of DIC-induced hepatoxicity in mice.

Abstract
BACKGROUND & AIMS Checkpoint inhibitor-related hepatitis (CPI-Hep) is an emerging clinical challenge. We aimed to gain insights into the immunopathology of CPI-Hep by comprehensively characterising myeloid and lymphoid subsets. METHODS CPI-treated patients with or without related hepatitis (CPI-Hep; n = 22 and CPI-noHep; n = 7) were recruited. Phenotypic and transcriptional profiling of peripheral immune subsets was performed and compared with 19 healthy controls (HCs). In vitro monocyte-derived macrophages (MoMFs) were assessed for activation and cytokine production. CD163, CCR2, CD68, CD3, CD8 and granzyme B expression was assessed using immunohistochemistry/immunofluorescence (n = 4). RESULTS A significant total monocyte depletion was observed in CPI-Hep compared with HCs (p = 0.04), along with a proportionate increase in the classical monocyte population (p = 0.0002) and significant upregulation of CCR2, CD163 and downregulation of CCR7. Soluble CD163 levels were significantly elevated in CPI-Hep compared with HCs (p <0.0001). In vitro MoMFs from CPI-Hep showed enhanced production of pro-inflammatory cytokines. CD8+ T cells demonstrated increased perforin, granzyme B, ICOS and HLA-DR expression in CPI-Hep. Transcriptional profiling indicated the presence of activated monocyte and enhanced effector CD8+ T cell populations in CPI-Hep. Immunohistochemistry demonstrated co-localisation of CD8+/granzyme B+ T cells with CD68+CCR2+/CD68+CD163+ macrophages in CPI-Hep liver tissue. CONCLUSIONS CPI-Hep is associated with activation of peripheral monocytes and an enhanced cytotoxic, effector CD8+ T cell phenotype. These changes were reflected by liver inflammation composed of CD163+/CCR2+ macrophages and CD8+ T cells. LAY SUMMARY Some patients who receive immunotherapy for cancer develop liver inflammation, which requires cessation of cancer treatment. Herein, we describe ways in which the white blood cells of patients who develop liver inflammation differ from those of patients who receive the same immunotherapy but do not experience liver-related side effects. Targeting some of the pathways we identify may help to prevent or manage this side effect and facilitate cancer treatment.

Abstract
Drug-induced liver injury (DILI) is a major side effect, sometimes can't be exactly evaluated by current approaches partly as the covalent modification of drug or its reactive metabolites (RMs) with proteins is a possible reason. In this study, we developed a rapid, sensitive, and specific analytical method to assess the hepatotoxicity induced by drug covalently modified proteins based on the quantification of the modified amino acids using toosendanin (TSN), a hepatotoxic chemical, as an example. TSN RM-protein adducts both in rat liver and blood showed good correlation with the severity of hepatotoxicity. Thus, TSN RM-protein adducts in serum can potentially serve as minimally invasive biomarkers of hepatotoxicity. Meanwhile, large-scale chemical proteomics analysis showed that at least 84 proteins were modified by TSN RMs in rat liver, and the bioinformatics analysis revealed that TSN might induce hepatotoxicity through multi-target protein-protein interaction especially involved in energy metabolism. These findings suggest that our approach may serve as a valuable tool to evaluate DILI and investigate the possible mechanism, especially for complex compounds.

Abstract
RATIONALE Eszopiclone, sold under the brand name Lunesta, is a new type of non-benzodiazepine hypnotic. Eszopiclone is a zopiclone dextrorotation, which is classified as a cyclopyrrolone. It functions by binding gamma-aminobutyric acid (GABA) receptors. Compared with benzodiazepines hypnotics, eszopiclone has higher selectivity for certain subunits of the GABA(A) receptor. So far, there are no reports about the elevation of serum enzymes or severe liver injury caused by eszopiclone. Here, we present a case report of acute liver injury following eszopiclone treatment in a patient with chronic hepatitis B virus (HBV). PATIENT CONCERNS The patient was a 53-year-old female with a 36-year history of positive HBV markers. Due to poor sleep, the patient took trazodone hydrochloride orally for 1 year. After hospital admission for positive hepatitis B pathogenic markers, abdominal distension, fatigue, and aggravation, she was treated with eszopiclone under the guidance of the mental health department. DIAGNOSES Her transaminase levels increased abnormally after eszopiclone treatment and rapidly decreased after drug withdrawal. This was determined to be an acute liver injury event. liver-protecting treatment was maintained. Considering the patient's anxiety and depression, the patient's family members refused a liver biopsy. OUTCOMES Transaminase levels decreased rapidly within one week, and the patient continued to take trazodone hydrochloride after discharge. No adverse events occurred in the follow-up period. LESSONS Sleep disorders are more common in patients with chronic diseases, especially patients with chronic liver disease. Recently, it has become common for patients with hepatitis B and C to use antidepressants along with antiviral treatment. Patients with chronic hepatitis B or C may have a threefold risk of liver dysfunction after receiving antituberculosis treatment.[1,2] A proinflammatory environment induced by actively replicating the hepatitis virus may alter the detoxication process and increase drug toxicity.[3] At this time, the safety of other drugs should be reevaluated. Although hepatitis and liver injury are listed as rare adverse reactions of eszopiclone, this case is the first to report the eszopiclone-involved acute liver injury.

Abstract
BACKGROUND Underage drinking is associated with health risk behaviors. Serum keratin-18 (CK18) levels are increased in liver diseases and may be biomarkers of outcome. The purpose of this study was to determine if the total CK18 (M65) or caspase-cleaved CK18 (M30) levels were different in adolescents admitted to hospital because of alcohol intoxication and controls with excluded liver diseases. METHODS A prospective study included 57 adolescents after alcohol use and 23 control subjects. The concentrations of M30 and M65 in the serum samples were evaluated using an enzyme-linked immunosorbent assay. RESULTS The median age was 15 (14-17) years and 49% were male. There were significant differences in M65 levels between the study and control groups (p = 0.03). The concentrations of M30 and M65 were insignificant in adolescents divided into subgroups according to blood alcohol concentrations (BAC). Significant positive correlations were found between BAC and M65 levels (p = 0.038; r = 0.3). In receiver operating characteristic (ROC) analysis M65 (cut-off = 125.966 IU/l, Se = 70.2%, Sp = 43.5%) allowed to differentiate between patients with and without alcohol intoxication (AUC = 0.66, p = 0.03). CONCLUSION M65 appears to be a promising non-invasive biomarker of hepatocyte injury during alcohol intoxication in adolescents. Moreover, a higher concentration of M65 may indicate early organ injury before the increase in the activity of liver enzymes, alanine aminotransferase (ALT) and aspartate aminotransferase (AST).

Abstract
AIMS Clinical trials showed that statin therapy decreased cardiovascular events without significantly raising the level of transaminases. However, the information in subjects with altered liver test at baseline is more limited. The objectives of this meta-analysis were to analyze the liver safety and cardiovascular benefit when using a statin-based lipid-lowering treatment compared to a less intensive treatment or placebo, in subjects with abnormal liver tests at baseline. DATA SYNTHESIS We performed a meta-analysis including randomized trials of statin-based lipid-lowering therapy versus less intensive lipid-lowering therapy or placebo, reporting worsening hepatic test (>3 ULN) and cardiovascular events in patients with abnormal liver tests at baseline. The random-effects model was performed. This meta-analysis was performed according to PRISMA guidelines. Five eligible trials, including 2548 patients were identified and considered eligible for the analyses. A more intensive statin-based lipid-lowering therapy were associated with a similar occurrence of serious alteration of liver tests (OR: 0.90, 95% confidence interval: 0.21-3.99; I2: 64%) compared to less intensive or placebo treatments. Likewise, more intensive lipid-lowering strategies were associated with a significant reduction in major cardiovascular events (OR: 0.34, 95% confidence interval: 0.17-0.70; I2: 66%). CONCLUSIONS In this study, a more intensive statin-based lipid-lowering treatment, compared with less intensive treatment or placebo, showed a similar incidence of worsening transaminases levels in patients with abnormal liver tests at baseline. Also, a reduction in cardiovascular events was observed when a more intensive lipid-lowering therapy was used.

Vitamin D deficiency exacerbates hepatic oxidative stress and inflammation during acetaminophen-induced acute liver injury in mice. Int Immunopharmacol 2021; 97:107716. [PMID: 33951559 DOI: 10.1016/j.intimp.2021.107716] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 04/20/2021] [Accepted: 04/20/2021] [Indexed: 12/19/2022]
Abstract
Several experiments confirmed that vitamin D3 protected against acetaminophen (APAP)-induced acute liver injury (ALI). This research aimed to evaluate the influence of vitamin D deficiency (VDD) on APAP-induced ALI. In VDD and VDD + APAP groups, mice were fed with VDD diet. In APAP and VDD + APAP groups, mice were intraperitoneally injected with a sublethal dose of APAP (150 mg/kg). A sublethal dose of APAP caused a slight elevation of ALT and AST. Interestingly, APAP-induced elevation of ALT and AST was aggravated in VDD-fed mice. APAP-induced hepatic necrosis was exacerbated in VDD-fed mice. In addition, APAP-induced hepatocyte death, measured using TUNEL assay, was exacerbated in VDD-fed mice. Additional experiment showed that APAP-induced hepatic GSH depletion and lipid peroxidation were exacerbated in VDD-fed mice. Moreover, APAP-induced upregulation of antioxidant genes, such as hepatic heme oxygenase-1 (Ho-1), glutathione peroxidase (Gshpx), superoxide dismutase 1 (Sod1) and catalase enzymes (Cat), was aggravated in VDD-fed mice. Although a sublethal dose of APAP did not cause hepatic inflammation, hepatic proinflammatory cytokines and chemokines, such as Tnf-α, Kc, Mcp-1 and Mip2, were upregulated in VDD-fed mice treated with APAP. These results provide experimental data that VDD exacerbates hepatic oxidative stress and inflammation during APAP-induced ALI.

Abstract
AIMS Cisplatin (CP), as an effective alkylating agent, is widely used in cancer treatment, while hepatotoxicity is one of its side effects. Gliclazide (GLZ), as an oral hypoglycemic drug, has antioxidant and anti-inflammatory properties. This study was designed to investigate the protective effect of GLZ against CP-induced hepatotoxicity in mice. METHODS In this experimental study, 64 adult male mice randomly were allocated into eight groups (8 mice/group). Control, GLZ (5, 10, and 25 mg/kg, orally), CP (10 mg/kg, single dose, intraperitoneally), and CP+GLZ (in three doses). GLZ was administrated for 10 consecutive days. CP was injected on the 7th day of the study. At the end of the experiment, hepatotoxicity was evaluated by serum and tissue biochemical, histopathological, and immunohistochemical assessments. RESULTS The data were revealed that CP increased oxidative stress (increased MDA and reduced GSH), liver damage enzymes (ALT, AST, and ALP), and immunoreactivity of caspase-3 in liver tissue of CP-injected mice. Also, CP induced histopathological changes such as eosinophilic of hepatocytes, dilatation of sinusoids, congestion, and proliferation of Kupffer cells. GLZ administration significantly ameliorated serum functional enzyme and hepatic oxidative stress markers in CP-injected mice. In addition, the histological and immunohistochemical alterations were ameliorated in GLZ-treated mice. Of the three doses, 10 and 25 mg/kg were more effective. CONCLUSIONS In conclusion, GLZ with its antioxidant, anti-inflammatory, and anti-apoptotic activities, can be suggested as a promising drug in the treatment of CP-induced hepatotoxicity.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 270:113816.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The well-known Chinese prescription, Xiaoyan Lidan Formula (XYLDF), possesses efficiency of heat-clearing, dampness-eliminating and jaundice-removing. It has long been used clinically for the treatment of hepatobiliary diseases due to intrahepatic cholestasis (IHC). However, the mechanism of XYLDF for its therapeutic effects remains elusive. AIM OF THE STUDY The study aimed to explore the potential targets for liver protective mechanism of XYLDF based on network pharmacology and experimental assays in ANIT-induced cholestatic hepatic injury (CHI) in rats. MATERIALS AND METHODS On the basis of the 29 serum migrant compounds of XYLDF elucidated by UPLC-TOF-MS/MS, a network pharmacology approach was applied for the mechanism prediction. Systematic networks were constructed to identify potential molecular targets, biological processes, and signaling pathways. And the interactions between significantly potential targets and active compounds were simulated by molecular docking. For the mechanism validation, an ANIT-induced rat model was used to evaluate the effects of XYLDF on CHI according to serum biochemistry, bile flow rates, histopathological examination, and the gene and protein expression including enzymes related to synthesis, export, and import of bile acid in liver and ileum, and those of inflammatory cytokines, analyzed by RT-qPCR and WB. RESULTS The results of network pharmacology research indicated TNF (TNF-α), RELA (NF-κB), NR1H4 (FXR), and ICAM1 (ICAM-1) to be the important potential targets of XYLDF for cholestatic liver injury, which are related to bile metabolism and NF-κB-mediated inflammatory signaling. And the molecular docking had pre-validated the prediction of network pharmacology, as the core active compounds of XYLDF had shown strong simulation binding affinity with FXR, followed by NF-κB, TNF-α, and ICAM-1. Meanwhile, the effects of XYLDF after oral administration on ANIT-induced CHI in rats exhibited the decreased levels of transaminases (ALT and AST), TBA, and TBIL in serum, raised bile flow rates, and markedly improved hepatic histopathology. Furthermore, consistent to the above targets prediction and molecular docking, XYLDF significantly up-regulated the expression of FXR, SHP, BSEP, and MRP2, and down-regulated CYP7A1 and NTCP in liver, and promoted expression of IBABP and OSTα/β in ileum, suggesting the activation of FXR-mediated pathway referring to bile acid synthesis, transportation, and reabsorption. Moreover, the lower levels of TNF-α in plasma and liver, as well as the reduced hepatic gene and protein expression of NF-κB, TNF-α, and ICAM-1 after XYLDF treatment revealed the suppression of NF-κB-mediated inflammatory signaling pathway, as evidenced by the inhibition of nuclear translocation of NF-κB. CONCLUSIONS XYLDF exhibited an ameliorative liver protective effect on ANIT-induced cholestatic hepatic injury. The present study has confirmed its mechanism as activating the FXR-regulated bile acid pathway and inhibiting inflammation via the NF-κB signaling pathway.

Abstract
Introduction: Liver injury induced by drugs is a serious clinical problem. Many circulating biomarkers for identifying and predicting drug-induced liver injury (DILI) have been proposed.Areas covered: Biomarkers are mainly predicated on the mechanistic understanding of the underlying DILI, often in the context of acetaminophen overdose. New panels of biomarkers have emerged that are related to recovery/regeneration rather than injury following DILI. We explore the clinical relevance and limitations of these new biomarkers including recent controversies. Extracellular vesicles have also emerged as a promising vector of biomarkers, although the biological role for EVs may limit their clinical usefulness. New technological approaches for biomarker discovery are also explored.Expert opinion: Recent clinical studies have validated the efficacy of some of these new biomarkers, cytokeratin-18, macrophage colony-stimulating factor receptor, and osteopontin for DILI prognosis. Low prevalence of DILI is an inherent limitation to DILI biomarker development. Furthering mechanistic understanding of DILI and leveraging technological advances (e.g. machine learning/omics) is necessary to improve upon the newest generation of biomarkers. The integration of omics approaches with machine learning has led to novel insights in cancer research and DILI research is poised to leverage these technologies for biomarker discovery and development.

Abstract
Acute paracetamol over dose-induced hepatotoxicity is considered an important medical hazard especially among women. Omega-3 long-chain polyunsaturated fatty acids (Omega-3 PUFAs) daily doses are nowadays recommended for their antioxidant and anti-inflammatory potentials. Fourier transform infrared (FTIR) spectroscopy is considered a reliable method in analyzing cellular alterations and is now efficiently used to diagnose several diseases and the efficacy of drugs even in the early stages. The aim of our study was to evaluate the hepatoprotective effect of Omega-3 PUFAs against paracetamol-induced hepatotoxicity in rats confirmed through measuring protein alterations in hepatocytes by FTIR. Rats were pretreated with Omega-3 PUFAs (50 and 100 mg/kg) for 21 days prior to oral ingestion of paracetamol. FTIR results revealed that Omega-3 PUFAs (50 mg/kg) limited the toxic effects of paracetamol by restoring the hepatic amide I to amide II ratio. In addition; biochemical analyses demonstrated that serum ALT, AST, Cholesterol, LDL-cholesterol and Il-6 levels as well as hepatic TNF-α, MDA, NOx levels were decreased. Besides; serum HDL-cholesterol level and hepatic GSH level were increased. Histopathological examinations of hepatic sections validated the hepatoprotective potential. The overall effect of this dose was comparable to those of the usual recommended hepatoprotective supplement; silymarin. In conclusion; it would be recommended to use Omega-3 PUFAs in low doses on daily bases as a hepatoprotective agent.

Abstract
Methotrexate (MTX) is used as an effective chemotherapeutic agent against autoimmune diseases and tumors. Oxidative stress and inflammation are involved in the pathogenesis of MTX-induced damage. This study aimed at examining the ameliorating effects of apigenin (API) as a natural antioxidant on MTX-induced hepatotoxicity. The rats were classified into four groups: group I: normal saline-treated, group II: MTX-treated (20 mg/kg, ip, single dose at day 7), group III: MTX + API-treated (20 mg/kg, po), and group IV: API-treated. API was administrated for 9 days. Alanine aminotransferase (ALT), alkaline phosphatase (ALP), and aspartate aminotransferase (AST) were used as biochemical factors of MTX-induced hepatic injury. In hepatic tissues, the levels of malondialdehyde (MDA), nitric oxide (NO), glutathione (GSH), and activities of antioxidant enzymes such as catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) as oxidative stress markers along with inflammatory factors such as tumor necrosis factor-alpha (TNF-α) and interleukin 1 beta (IL-1β) were assessed. Our results showed that MTX administration significantly increased ALP, ASP, ALT, MDA, NO, TNF-α, and IL-1β levels and significantly decreased antioxidant factors such as GSH, CAT, GPx, and SOD. The API pretreatment group showed a significant rise in hepatic antioxidant markers, besides significant reductions in the serum levels of AST, ALT, and ALP and hepatic content of MDA, TNF-α, NO, and IL-1β. In addition, the hepatoprotective effect of API was confirmed by histological evaluation of the liver. API can prevent MTX-induced hepatotoxicity through mitigation of oxidative stress and inflammation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pain is the commonest symptom of a disease and the percentage of persons manifesting one form of pain is growing globally. Aframomum melegueta (AM) is commonly used by traditional doctors as medication for many ailments such as body pains and rheumatism because it possesses anti-inflammatory, anti-allergenic, antiviral, anti-ageing and anti-tumour phytochemical agents. AIM OF THE STUDY Traditionally a botanical remedy in the management of pain was assessed. A common tropical plant Aframomum melegueta (AM) was evaluated for the amelioration of pain. For further pharmacologic understanding sensitive marker were used to assess the effect of the extract on the organ as a multifaceted approach to the evaluation of safety and analgesic efficacy. MATERIALS AND METHOD Sensitive biomarkers such as troponin-T (CTnT), cardiac troponin-I (CTnI), interleukin-beta (IL-β), interleukin-6 (IL-6), tumor necrosis factor-alfa (TNF-α) were evaluated using the enzyme-linked immunosorbent assay (ELISA) method and electrocardiographic parameters were also evaluated. The dynamics of concentrations of the various subfamilies of cytochrome were also assessed using ELISA in the evaluation of thirty-day oral AM, while histopathological changes of organs were also observed. RESULTS Thirty-day oral AM doses 40 mg/kg and 80 mg/kg showed analgesic potential but influenced IL-6 level, IL-1β, TNF-α and P-LCR. Electrocardiographic parameters showed the extract had arrhythmogenic effects the other cardiac parameters influenced was CTnT. The testicular alfa-fetoprotein and prostate specific antigen were also influenced. There were also some histopathological changes. CONCLUSIONS The extract showed analgesic, anti-oxidant and anti-inflammatory potential with possible adverse effects consistent with testicular and prostate cancers, cardiovascular complication, hepatic congestion and cholestasis.

Abstract
ABSTRACT This study objected to evaluate the accuracy of the gamma-glutamyl transpeptidase-to-platelet ratio (GPR), aspartate aminotransferase-to-platelet ratio index (APRI), red cell distribution width (RDW), and fibrosis-4 index (FIB4) index, compared with liver biopsy (LB), in predicting the severity of inflammation in drug-induced liver injury (DILI) patients.We evaluated patients with DILI who were followed at the First Hospital of Jilin University and underwent LB. Accuracy of each method was analyzed using ROC analysis. Classifications of liver inflammation included G0-4.One hundred fifty six DILI patients were included with LB and complete medical records. 62.8% (98), 39.1% (61), and 16.7% (26) were classified as ≥G2, ≥G3, or G4, respectively. The AUROCs, by degree of inflammation, were: ≥G2: GPR: 0.654, RDW: 0.635, APRI: 0.728, and FIB4: 0.739; ≥G3: GPR: 0.623, RDW: 0.703, APRI: 0.777, and FIB4: 0.781; and G4: GPR: 0.556, RDW: 0.647, APRI: 0.729, and FIB4: 0.714. To predict ≥G2 inflammation, there were no differences between the AUROCs for GPR, RDW, APRI, and FIB4. To predict ≥G3 inflammation, the AUROCs for FIB4 and APRI were higher than that for GPR (0.781 vs 0.623, P < .01; 0.777 vs 0.623, P < .05). As for G4 inflammation, the AUROCs for FIB4 and APRI were also higher than GPR (0.714 vs 0.556, P < .05, 0.729 vs 0.556, P < .05).When the level of inflammation was higher than G2 in patients with DILI, it could be predicted using APRI and FIB4 as non-invasive markers for this condition.

Abstract
BACKGROUND Epimedii Folium (EF) is commonly used for treating bone fractures and joint diseases, but the potential hepatotoxicity of EF limits its clinical application. Our previous study confirms that EF could lead to idiosyncratic drug-induced liver injury (IDILI) and hepatocyte apoptosis, but the mechanism remains unknown. Studies have shown that NLRP3 inflammasome plays an important role in the development of various inflammatory diseases such as IDILI. Specific stimulus-induced NLRP3 inflammasome activation may has been a key strategy for lead to liver injury. Therefore, main compounds derived from EF were chosen to test whether the ingredients in EF could activate the NLRP3 inflammasome and to induce IDILI. METHODS Bone-marrow-derived macrophages (BMDMs) were treated with Icariside I, and then stimulated with inflammasome stimuli and assayed for the production of caspase-1 and interleukin 1β (IL-1β) and the release of lactate dehydrogenase (LDH). Determination of intracellular potassium, ASC oligomerization as well as reactive oxygen species (ROS) production were used to evaluate the stimulative mechanism of Icariside I on inflammasome activation. Mouse models of NLRP3 diseases were used to test whether Icariside I has hepatocyte apoptosis effects and promoted NLRP3 inflammasome activation in vivo. RESULTS Icariside I specifically enhances NLRP3 inflammasome activation triggered by ATP or nigericin but not SiO2, poly(I:C) or cytosolic LPS. Additionally, Icariside I does not alter the activation of NLRC4 and AIM2 inflammasomes. Mechanically, Icariside I alone does not induce mitochondrial reactive oxygen species (mtROS), which is one of the critical upstream events of NLRP3 inflammasome activation; however, Icariside I increases mtROS production induced by ATP or nigericin but not SiO2. Importantly, Icariside I leads to liver injury and NLRP3 inflammasome activation in an LPS-mediated susceptibility mouse model of IDILI, but the effect of Icariside I is absent in the LPS-mediated mouse model pretreated with MCC950, which is used to mimic knockdown of NLRP3 inflammasome activation. CONCLUSIONS Our study reveals that Icariside I specifically facilitates ATP or nigericin-induced NLRP3 inflammasome activation and causes idiosyncratic hepatotoxicity. The findings suggest that Icariside I or EF should be avoided in patients with diseases related to ATP or nigericin-induced NLRP3 inflammasome activation, which may be risk factors for IDILI.

Abstract
Acetaminophen (N-acetyl-p-aminophenol, APAP) overdose is the most common cause of drug-induced liver injury (DILI). Although the primary hepatic damage is induced by APAP-derived toxic intermediates resulting from cytochrome P450 metabolism, immune components also play an important role in DILI pathophysiology. Aedes aegypti saliva is a source of bioactive molecules with in vitro anti-inflammatory and immunomodulatory activities. However, evidences on the therapeutic use of Ae. aegypti salivary preparations in animal models of relevant clinical conditions are still scarce. Thus, the present study was designed to evaluate the protective role of Ae. aegypti saliva in a murine model of APAP-induced DILI. C57BL/6 mice were exposed to Ae. aegypti bites 2 hours after APAP overdose. Biochemical and immunological parameters were evaluated in blood and liver samples at different time points after APAP administration. Exposure to Ae. aegypti saliva attenuated liver damage, as demonstrated by reduced hepatic necrosis and serum levels of alanine aminotransferase in APAP-overdosed mice. The levels of hepatic CYP2E1, the major enzyme responsible for the bioactivation of APAP, were not changed in Ae. aegypti exposed animals, suggesting no effects in the generation of hepatotoxic metabolites. On the other hand, mice treated with Ae. aegypti saliva following APAP overdose presented lower serum concentration of TNF-α, IL-6, IL-1β and IL-10, as well as reduced frequency of inflammatory cell populations in the liver, such as NKT cells, macrophages and dendritic cells. These findings show that Ae. aegypti saliva has bioactive molecules with therapeutic properties and may represent a prospective source of new compounds in the management of DILI-associated inflammatory disorders and, perhaps, many other inflammatory/autoimmune diseases.

Abstract
Vanishing bile duct syndrome is a rare acquired condition, characterized by progressive loss of intrahepatic bile ducts leading to ductopenia and cholestasis. It can be associated with infections, ischemia, drug adverse reactions, neoplasms, autoimmune disease, and allograft rejection. Prognosis is variable and depends on the etiology of bile duct injury. We report the case of a 25-year-old female with cholestatic hepatitis and concomitant intakes of hepatotoxic substances, such as garcinia, field horsetail, and ketoprofen. On suspicion of a drug-induced liver injury, the drugs were promptly withdrawn and ursodeoxycholic acid was started with initial clinical and laboratory improvement, and the patient was discharged from the hospital. One month later, she had a new increase in bilirubin levels and canalicular enzymes, requiring a liver biopsy that showed significant loss of intrahepatic bile ducts, which was compatible with vanishing bile duct syndrome. This was confirmed by using cytokeratin 19 on immunohistochemistry. There was subsequent lymph node enlargement in several chains, and relevant weight loss. Histological analysis of a cervical lymph node revealed nodular sclerosis-subtype classic Hodgkin lymphoma. In this setting, vanishing bile duct syndrome was related to Hodgkin lymphoma and a drug-induced liver injury overlap, leading to progressive cholestasis with a worse prognosis. The patient's response to chemotherapy was poor, requiring biological therapy with brentuximab vedotin. It is crucial for physicians to create a broad differential diagnosis in suspected vanishing bile duct syndrome patients, especially to rule out malignancies.

Abstract
Liver failure is a serious hepatic dysfunction with high mortality. This work aimed to investigate the effect of a famous probiotic and drug, Lactobacillus reuteri DSM 17938, on liver failure in rats. Sprague-Dawley rats were gavaged with 3 × 109 CFU of DSM 17938 for 7 days. d-galactosamine was intraperitoneally injected to induce acute liver failure on the eighth day. Samples were collected to determine the liver function, serum cytokines levels, terminal ileum and liver histology, gut microbiota, metabolome and transcriptome. Our results showed that pretreatment with DSM 17938 not only reduced the elevation in serum alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transferase, IL-1α, IL-2, IL-18, M-CSF, and MIP-3α levels but also alleviated histological abnormalities of both the terminal ileum and liver induced by d-galactosamine. Additionally, DSM 17938 reduced d-galactosamine-induced enrichment of some taxa of gut Actinobacteria or Firmicutes, including abundant pathogens such as Actinomycetales, Coriobacteriaceae, Staphylococcaceae and Enterococcaceae. Furthermore, DSM 17938 reduced the d-galactosamine-induced increase in not only fecal metabolites such as trisaminol and lithocholic acid but also the transcription of liver inflammatory genes, such as Ccl2, Ccl7, Ccl11, Ccl12, Il6, Il11, Il20rb, Mmp3 and Mmp10. Downregulation of retinol metabolism and PPAR signaling pathway as well as upregulation of viral protein interaction with cytokine and cytokine receptor and central carbon metabolism in cancer signaling pathway were involved in the mechanism of L. reuteri DSM 17938 alleviating liver failure. Our findings suggested that DSM 17938 is a potential probiotic for the prevention or treatment of liver failure.
