This study aimed to investigate and analyze the clinical and immunological features of patients with anti-melanoma differentiation-associated gene-5 antibody-positive dermatomyositis (MDA5 + DM) complicated with clinical liver dysfunction. A cohort of 85 patients diagnosed with MDA5 + DM admitted into Peking University People's Hospital from 2006 to 2023 were retrospectively enrolled in this study. Clinical characteristics and survival status were collected and analyzed. Clinical liver dysfunction occurred in 28% (24/85) of MDA5 + DM patients. Patients with clinical liver dysfunction were more likely to have muscle impairment (83.3% vs. 52.5%, P = 0.009) and rapidly progressive ILD (72.7% vs. 47.4%, P = 0.027). Lactate dehydrogenase (LDH) (378.5 (296.0,453.8) U/L vs. 280.0 (218.0,355.0) U/L, P = 0.002) and ferritin (FER) (883.0 (279.8,2100.5) ng/mL vs. 293.5.0 (84.0,862.7) ng/mL, P = 0.040) were significantly elevated and total numbers of lymphocytes (827.2 ± 517.2 /μL vs. 1301.8 ± 720.9 /μL, P = 0.042), and CD4 + T cells (403.8 ± 315.9 /μL vs. 548.6 ± 257.7 /μL, P = 0.045) were significantly decreased in patients with clinical liver function. Muscle weakness (OR 5.184, 95% CI 1.305, 20.595, P = 0.019) was identified as an independent risk factor for clinical liver dysfunction. Clinical liver dysfunction was identified as an independent risk factor for poor prognosis in patients with MDA5 + DM (HR = 4.030, 95% Cl 1.233, 13.176, P = 0.021), with an 18-month survival rate of 69%. Liver dysfunction is one of the extramuscular manifestations in patients with MDA5 + DM and might be associated with a poor prognosis. Key Points There were 28% of patients with MDA5 + DM in our study who experienced clinical liver dysfunction, showing different features compared to patients without clinical liver dysfunction: • Clinical liver dysfunction was defined as an AST or ALT level more than double the ULN and the AST or ALT level divided by its ULN was greater than the CK level divided by its ULN. In addition to these two aminotransferases, GGT, ALP, and HBDH, LDH and ferritin were also found to be elevated in patients with clinical liver dysfunction.The proportion and total number of lymphocytes, and the number of CD4 + T cells were all lower in these patients. • Patients with clinical liver dysfunction were more likely to suffer from RP-ILD and muscle involvement, including myalgia and muscle weakness, and multivariate logistic regression analysis demonstrated that muscle weakness was identified as an independent factor for clinical liver dysfunction. • Patients with clinical liver dysfunction seemed to have a poor prognosis. The mortality rate was greater, and the overall survival was shorter. Moreover, clinical liver dysfunction was identified as an independent risk factor for the poor prognosis. [ABSTRACT FROM AUTHOR]

Background: Liver dysfunction is a known risk factor in the cardiovascular field. It specifically increases perioperative risk in patients undergoing coronary bypass surgery. Since percutaneous coronary intervention (PCI) is the much less invasive procedure for the treatment of coronary artery disease, we aimed to assess the relationship of liver dysfunction with outcomes in patients undergoing PCI. Methods: Three libraries were searched (MEDLINE, Web of Science and The Cochrane Library). We performed a meta-analysis of all studies in patients who underwent PCI that provided information on the presence or absence of liver dysfunction. Primary outcome was short-term mortality. Secondary outcomes were major adverse cardio- and cerebrovascular events (MACCE), bleeding and acute kidney injury. Random-effects model was applied. Results: Five studies were selected and the data from 10,710,317 patients were included in the final analysis. In comparison with the absence of liver dysfunction, patients with liver dysfunction were associated with higher short-term mortality (OR 2.97, 95%CI 1.23–7.18, p = 0.02), higher MACCE (OR 1.42, 95%CI 1.08–1.87, p = 0.01), and higher bleeding (OR 2.23, 95%CI 1.65-3.00, p < 0.01). There was no significant difference regarding acute kidney injury (OR 1.20, 95%CI 0.50–2.87, p = 0.69). Conclusions: The analysis suggests that liver dysfunction in patients undergoing PCI is independently associated with higher risk of short-term mortality and increased occurrence of MACCE and bleeding. However, there appears to be no association to acute kidney injury. [ABSTRACT FROM AUTHOR]

Brain injury is the leading cause of mortality among patients who survive cardiac arrest (CA). Clinical studies have shown that the presence of post-CA hypoxic hepatitis or pre-CA liver disease is associated with increased mortality and inferior neurological recovery. In our in vivo global cerebral ischemia model, we observed a larger infarct area, elevated tissue injury scores, and increased intravascular CD45+ cell adhesion in reperfused brains with simultaneous hepatic ischemia than in those without it. In the ex vivo brain normothermic machine perfusion (NMP) model, we demonstrated that addition of a functioning liver to the brain NMP circuit significantly reduced post-CA brain injury, increased neuronal viability, and improved electrocortical activity. Furthermore, significant alterations were observed in both the transcriptome and metabolome in the presence or absence of hepatic ischemia. Our study highlights the crucial role of the liver in the pathogenesis of post-CA brain injury. Synopsis: The liver function in post-cardiac arrest brain injury is not known and was investigated in a pig model of global cerebral ischemia. The frontal lobe infarct area and temporal lobe immune cell adhesion were increased in the ischemic brains in the presence of concurrent hepatic ischemia. Ex vivo, presence of a functioning liver improved neuronal viability, cytoarchitecture, and electrocortical activity post-CA brain injury. Transcriptomics and metabolomics analyses suggest that the liver protects from post-CA brain injury by increased production of ketone bodies. The liver function in post-cardiac arrest brain injury is not known and was investigated in a pig model of global cerebral ischemia. [ABSTRACT FROM AUTHOR]

Background: Early detection of liver dysfunction is crucial for timely intervention and management. Traditional liver function tests (LFTs) have limitations in sensitivity and specificity, necessitating the evaluation of newer diagnostic criteria. Objective: This study aims to compare the efficacy of different diagnostic criteria including Standard LFTs, Enhanced Liver Fibrosis (ELF) Test in detecting early liver dysfunction. Methods: A retrospective analysis was conducted on 125 patients suspected of early liver dysfunction at a tertiary care center. Diagnostic efficacy was assessed through sensitivity, specificity, and odds ratios calculated for each diagnostic criterion. Statistical significance was determined using p-values.

Objective Community-acquired pneumonia with abnormal liver function is not uncommon. There is no systematic study on the clinical characteristics of liver dysfunction in children with community-acquired pneumonia. We aimed to evaluate the characteristics and prognosis of liver dysfunction in children with community-acquired pneumonia. Methods This study was a multicenter prospective study involving 26 hospitals in Sichuan Province from June 2020 to June 2021. The characteristics of liver dysfunction in children with community-acquired pneumonia were recorded and analyzed according to different factors such as age, medical condition, level of transaminase in liver function, and time for liver function recovery. Results A total of 4,623 hospitalized children with pneumonia were included. Among them, 592 children had liver dysfunction, accounting for the 12.8% (592/4,623). The degree of liver function injury was more obvious in infants and in children of severe pneumonia group (average ranks were 288.95 and 319.34). The liver lesion was more serious in the group of children less than 1 year old (p = 0.000). The median time to recovery of liver function was 8 days (interquartile range: 6–15.5 days), whereas the fastest recovery was 3 days, and the longest recovery period was 162 days. Conclusion Community-acquired pneumonia with abnormal liver function is very common. Young age and severe pneumonia are risk factors for liver dysfunction. The recovery time of liver enzymes is not short. Infants and children with severe pneumonia need closer follow-up. [ABSTRACT FROM AUTHOR]

Summary: Context: Hepatic and renal damages manifest in patients with acute or chronic heart failure after the incidence of myocardial infarction (MI). Objective: Our objective in this study was aimed to investigate the protective effects of coenzyme Q10 (CoQ10) and taurine, which are bioactive compounds with protective functions, on liver and kidney toxicity rat exposed to isoprenaline, a popular tool for MI induction. Materials and methods: Following two (2) consecutive days of exposure to isoprenaline (200 mg/kg, i.p.), adult Wistar rats were treated with CoQ10 (10 mg/kg, i.p.) and taurine (100 mg/kg, i.p.) singly and in combination for 19 days. Following 21 days of experimentation, blood, liver and kidney were collected for biochemical and histological studies indicative of hepatic and kidney damage. Results: Our result showed that CoQ10 and taurine significantly decreased serum LDH, AST, ALT, and ALP, indicative of hepatic damage compared to isoprenaline groups. The increased creatinine and urea release suggestive of kidney dysfunction were suppressed by CoQ10 and taurine relative to the isoprenaline group. Additionally, CoQ10 and taurine significantly reversed isoprenaline-mediated oxidative stress-induced liver and kidney damage, which are shown by decreased malondialdehyde and nitrite accompanied by increased antioxidants (SOD, CAT, GST, GSH). Modifications to cellular histoarchitectural and fibrosis of the hepatic and renal tissues were attenuated by CoQ10 and taurine therapy. Discussion and conclusion: The findings from this study suggest that CoQ10 and taurine supplements may prevent isoprenaline-induced hepatorenal dysfunctions, possibly by alleviating oxidative stress and histoarchitectural protective functions of the hepatic and kidney cells.

BACKGROUND: Exercise has been widely recognized in the prevention and treatment of diabetes. Aerobic exercise has become an important part of the treatment of type 1 diabetes. However, the effect of treadmill exercise on the metabolism and chronic neuroinflammation of type 1 diabetes in different sexes needs further discussion. OBJECTIVE: To study the effects of treadmill exercise on metabolism and chronic neuroinflammation in type 1 diabetes mice of different sexes. METHODS: Forty C57BL/6 mice were divided into male group and female group, with 20 mice in each group. Then, a diabetes model was established by continuous injection of streptozotocin at 80 mg/kg for 3 days. Ten rats from each group were randomly selected to perform 6-week treadmill exercise as the diabetes+exercise group and another 10 rats from each group were selected as the diabetes group. Serum sex hormones, liver tissue oxidative stress, brain tissue inflammatory factors, and liver pathology were detected, and Morris water maze was performed for the observation of behavioral changes in mice. RESULTS AND CONCLUSION: Compared with the diabetes group, the diabetes+exercise group delayed the rise of blood sugar in type 1 diabetes mice (P < 0.05) and showed a significant reduction in serum follicle-stimulating hormone, luteinizing hormone, liver superoxide dismutase, malondialdehyde, brain tumor necrosis factor α, interleukin-6 and interleukin-1β levels (P < 0.01), while serum estradiol, progesterone, estrogen, and liver glutathione peroxidase protein levels were significantly increased (P < 0.01, P < 0.05). Compared with male type 1 diabetes mice, female type 1 diabetes mice had significantly higher estradiol levels and lower luteinizing hormone levels (P < 0.05). Compared with the male diabetes+exercise group, the female diabetes+exercise group had lower liver glutathione peroxidase levels (P < 0.05). Compared with type 1 diabetes mice, the escape latency of exercise training mice was shorter (P < 0.01). In male mice, exercises significantly increased the time and platform crossing times of type 1 diabetes mice in the target quadrant (P < 0.01 or P < 0.05), while in female mice, exercises significantly increased the time of type 1 diabetes mice in the target quadrant (P < 0.05). Correlation analysis results showed that the levels of follicle-stimulating hormone, luteinizing hormone, progesterone, superoxide dismutase, malondialdehyde, tumor necrosis factor α, and interleukin-6 were positively correlated with the level of interleukin-1β (P < 0.05 or P < 0.01), whereas the levels of estradiol and progesterone were negatively correlated with the levels of superoxide dismutase, malondialdehyde, tumor necrosis factor α, interleukin-6 and interleukin-1β (P < 0.05 or P < 0.01). Overall, there are sex differences in the effects of treadmill exercise on metabolic indicators and chronic neuroinflammatory regulation in diabetes mice. Sex hormones are an important variable of treadmill exercise in the metabolic, inflammatory and cognitive responses in diabetes mice. [ABSTRACT FROM AUTHOR]

Abstract Liver-related side effects are a known complication of treatment with elexacaftor/tezacaftor/ivacaftor (ETI) for cystic fibrosis (CF). Gilbert’s syndrome is caused by a genetic mutation that reduces activity of the enzyme UDP glucuronosyltransferase 1 polypeptide A1 (UGT1A1), causing elevated levels of unconjugated bilirubin in the blood and duodenal bile. The presence of Gilbert’s syndrome and CF might represent additive risk factors for liver-related adverse events during ETI treatment. This case series describes six people with CF (pwCF) in whom previously unknown Gilbert’s syndrome was unmasked after initiation of treatment with ETI. Although all patients had some level of hepatic dysfunction and/or elevated levels of bilirubin after initiation of ETI, the clinical course varied. Only one patient had to stop ETI therapy altogether, while the others were able to continue treatment (some at a reduced dosage and others at the full recommended daily dosage). All patients, even those using a lower dosage, experienced clinical benefit during ETI therapy. Gilbert’s syndrome is not a contraindication for ETI therapy but may be mistaken for a risk factor for liver-related adverse events in pwCF. This is something that physicians need to be aware of in pwCF who show liver adverse events during ETI therapy.

Proline henagliflozin, a novel selective inhibitor of sodium glucose cotransporter 2, is a treatment for type 2 diabetes mellitus. We designed a parallel‐group, open‐label, and multicenter study to evaluate the pharmacokinetic (PK), pharmacodynamic (PD), and safety profiles of henagliflozin in Chinese subjects with varying degrees of liver dysfunction. Thirty‐two subjects were enrolled and divided into four groups based on liver function (normal liver function, mild, moderate, or severe liver dysfunction). The area under the plasma concentration from time zero to infinity of henagliflozin in subjects with mild liver dysfunction, moderate liver dysfunction, and severe liver dysfunction compared with normal liver function was increased by 137%, 197%, and 204%, respectively. The maximum plasma concentration was also increased by 123%, 129%, and 139%, respectively. PK parameters of three metabolites varied to different degrees in the liver dysfunction groups than in the normal liver function group. The mean accumulative excretion amounts and fraction of dose excreted in urine expressed as a percentage were all increased with the decrease of liver function. The PD parameters were significantly higher in liver dysfunction groups than those in the normal liver function group. However, the urine creatinine (UCr) was not significantly different among the groups. No notable adverse events or adverse drug reactions were observed. Due to the higher exposures in subjects with liver dysfunction, the benefit: risk ratio should be individually assessed because the long‐term safety profile and efficacy have not been specifically studied in this population.

Background and Aim: Abnormal liver biochemistry (ALB) is common among patients with COVID‐19 infection due to various factors. It is uncertain if it persists after the acute infection. We aimed to investigate this. Methods: A multicenter study of adult patients hospitalized for COVID‐19 infection, with at least a single abnormal liver function test, was conducted. Detailed laboratory and imaging tests, including transabdominal ultrasound and FibroScan, were performed at assessment and at 6‐month follow‐up after hospital discharge. Results: From an initial cohort of 1246 patients who were hospitalized, 731 (58.7%) had ALB. A total of 174/731 patients fulfilled the inclusion criteria with the following characteristics: 48.9% patients had severe COVID‐19; 62.1% had chronic liver disease (CLD); and 56.9% had metabolic‐associated fatty liver disease (MAFLD). ALB was predominantly of a mixed pattern (67.8%). Among those (55.2%) who had liver injury (aspartate aminotransferase/alanine aminotransferase >3 times the upper limit of normal, or alkaline phosphatase/γ‐glutamyl transferase/bilirubin >2 times the upper limit of normal), a mixed pattern was similarly predominant. Approximately 52.3% had normalization of the liver lunction test in the 6‐month period post discharge. Patients with persistent ALB had significantly higher mean body mass index (BMI) and serum low‐density lipoprotein (LDL), higher rates of MAFLD and CLD, higher mean liver stiffness measurement and continuous attenuated parameter score on FibroScan, and higher rates of liver injury on univariate analysis. Multivariate analysis was not statistically significant. Conclusions: Approximately 47.7% of COVID‐19 patients were found to have persistent ALB up to 6 months following the acute infection, and it was associated with raised BMI, elevated serum LDL, increased rates of MAFLD and CLD, and higher rates of liver injury on univariate analysis, but not on multivariate analysis.

The letter addresses concerns and seeks clarification on a study titled "Correlation between Bilirubin Elimination with the Cytokine Adsorber CytoSorb® and Mortality in Critically Ill Patients with Hyperbilirubinemia." The authors express doubts about using mortality as the primary outcome measure in critically ill patients due to the variability in sepsis phenotypes. They also question the effectiveness of the blood purification technique, CytoSorb, in reducing bilirubin concentration and highlight the importance of mass balance calculations. The authors reference previous studies that demonstrate the capability of CytoSorb to efficiently remove bilirubin over 24 hours. They conclude that the data refute a study suggesting saturation of the CytoSorb adsorber after 6 hours. [Extracted from the article]

Liver-related side effects are a known complication of treatment with elexacaftor/tezacaftor/ivacaftor (ETI) for cystic fibrosis (CF).

Background. A significant proportion of couples worldwide suffer from infertility associated with polycystic ovary syndrome (PCOS). PCOS is characterized by increased androgen synthesis in the theca cells of the ovaries, hyperandrogenemia and ovarian dysfunction in women. Most of the clinical symptoms and altered levels of blood biomarkers in PCOS patients point to metabolic dysregulation and adaptive changes as key underlying mechanisms of disease development. Since the liver is the metabolic center of the body and participates in steroid-hormonal detoxification, pathological changes in it can contribute to endocrine disorders through the liver-ovary axis. Of particular interest is hyperglycemia, changes in secretory proteins of the liver and insulin sensitivity, which affect the maturation of ovarian follicles and can potentially lead to female infertility. Objective of the review: to provide an understanding of the new metabolic mechanisms underlying PCOS, which lead to the disease and its exacerbation, as well as to summarize therapeutic approaches to the correction of PCOS complications, in particular, liver function disorders using the drug Hepatomunil. Analysis of literary data. This review presents the relationship and underlying mechanistic basis between PCOS and metabolic disorders in women by summarizing the main pathologic features of the disease. Most symptoms of PCOS are associated with insulin resistance, type II diabetes, decreased levels of sex hormone-binding globulin, increased levels of alanine aminotransferase and aspartate aminotransferase, which may indicate liver dysfunction. The metabolic profile and function of the ovaries can be affected by any pathological changes in the levels of systemic metabolism and/or in peripheral organs, in particular the liver, which serves as the metabolic center of the body, mediating its effects through the liver-ovary axis. Conclusions. Despite the lack of a clear protocol for the correction of liver function disorders and non-alcoholic fatty liver disease in PCOS patients, lifestyle modification should be the basis. Drugs that improve metabolism, as well as hepatoprotectors with immunomodulatory properties (the drug Hepatomunil) may have positive prospects for use. [ABSTRACT FROM AUTHOR]

Global pandemic of obesity contributes to increasing the risk of diabetes and non-alcoholic fatty liver disease (NAFLD). To find an alternative approach to lower the risk caused by obesity. Aims: We investigated the antidiabetic and hepatoprotective activity of black rice bran extract (BRE) in obese, insulin-resistant rats induced by a high-fat diet (HFD). Main methods: After HFD feeding, the parameters related to glucose, lipid profiles, and liver injury were determined. Key findings: Rats on a HFD exhibited significantly elevated plasma glucose and lipid levels, as well as increased liver enzyme activities (aspartate transaminase and alanine transaminase), relative to the control group. Interestingly, those parameters in the BRE-treated group were significantly decreased. We investigated the liver histological study, and the BRE-treated group showed to ameliorate the liver injury accompanied by lower inflammatory and apoptotic markers. Significance: Our findings suggest that BRE has the potential to be used as a dietary supplement to lessen metabolic dysregulation and prevent liver impairment.

Adverse events caused by real-world drug utilization has become one of the leading causes of death and an urgent issue in the field of toxicology. Cardiovascular disease is now the leading cause of fatal diseases in most countries, especially in the elderly population who often suffer from multiple diseases and need long-term multidrug therapy. Among which, statins have been widely used to lower bad cholesterol and regress coronary plaque mainly in patients with hyperlipidemia and atherosclerotic cardiovascular diseases (ASCVD). Although the real-world benefits of statins are significant, different degrees and types of adverse drug reactions (ADR) such as liver dysfunction and muscle injury, have a great impact on the original treatment regimens as well as the quality of life. This review describes the epidemiology, mechanisms, early identification and post-intervention of statin-associated liver dysfunction and muscle injury based on the updated clinical evidence. It provides systematic and comprehensive guidance and necessary supplement for the clinical safety of statin use in cardiovascular diseases.Keywords: statin, cardiovascular diseases, liver dysfunction, muscle injury, countermeasures

Post-liver transplant (LT) hepatic artery vasospasm is a vascular complication that is not well recognized and its incidence is not known. As a possible sequela to vasospasm, hepatic artery thrombosis is the second major cause of allograft failure after primary nonfunction and its reported incidence is 2.9% in adults and 8.3% in pediatric LT. Lacuna in knowledge regarding early hepatic artery vasospasm post-LT makes it a difficult condition to diagnose and treat, as the initial ischemic insult on graft can have devastating consequences. We report a case of pediatric progressive familial intrahepatic cholestasis type 3-related chronic liver disease who underwent cadaveric orthotopic LT and postoperatively developed fever, worsening hypotension, and elevated liver enzymes with an absence of arterial flow in intrahepatic branches on Doppler ultrasound. Suspecting early hepatic artery thrombosis, the patient was re-explored and the graft hepatic artery was found to be in a state of vasospasm. Following the infusion of intra-arterial papaverine, urokinase, and intravenous nicorandil, there was an improvement in blood flow. The patient responded well and was discharged on postoperative day 23 with normal liver enzymes.

Abstract Alcohol consumption and metabolic syndrome(MetS), both prevalent in the general population, frequently co-occur. They are recognized as significant contributors to liver dysfunction, yet their combined effect is often challenging to delineate. This study delves into the compounding influence of alcohol consumption and metabolic disorder on liver dysfunction within an elderly demographic in Zhejiang Province, China. Our findings spotlight a heightened risk of liver dysfunction among females, younger individuals, rural dwellers, those with minimal educational attainment, single individuals, and those diagnosed with MetS. We also discerned a positive correlation correlation between the number of MetS components and the propensity for liver dysfunction. Furthermore, the risk of liver dysfunction escalated in tandem with the frequency of alcohol consumption. Interestingly, a prolonged abstinence period (≥ 5 years) seemed to mitigate this risk. Our research underscores the significance of refraining from excessive alcohol consumption, embracing a healthy lifestyle, and managing MetS components-especially triglyceride levels-for effective prevention of liver dysfunction.

ABSTRACTS-amlodipine, a commonly prescribed antihypertensive agent, is widely used in clinical settings to treat hypertension. However, the potential adverse effects of long-term S-amlodipine treatment on the liver remain uncertain, given the cautionary recommendations from clinicians regarding its administration in individuals with impaired liver function. To address this, we conducted a study using an eight-week-old male rat model and administered a daily dose of 0.6 ~ 5 mg/kg of S-amlodipine for 7 weeks. Our findings demonstrated that 1.2 ~ 5 mg/kg of S-amlodipine treatment induced liver inflammation and associated dysfunction in rats, further in vitro experiments revealed that the observed liver inflammation and dysfunction were not attributable to direct effects of S-amlodipine on the liver. Metagenome sequencing analysis revealed that S-amlodipine treatment led to alterations in the gut microbiome of rats, with the bloom of E. coli (4.5 ~ 6.6-fold increase) and a decrease in A. muciniphila (1,613.4 ~ 2,000-fold decrease) and B. uniformis (20.6 ~ 202.7-fold decrease), subsequently causing an increase in the gut bacterial lipopolysaccharide (LPS) content (1.4 ~ 1.5-fold increase in feces). S-amlodipine treatment also induced damage to the intestinal barrier and increased intestinal permeability, as confirmed by elevated levels of fecal albumin; furthermore, the flux of gut bacterial LPS into the bloodstream through the portal vein resulted in an increase in serum LPS content (3.3 ~ 4-fold increase). LPS induces liver inflammation and subsequent dysfunction in rats by activating the TLR4 pathway. This study is the first to show that S-amlodipine induces liver inflammation and dysfunction by perturbing the rat gut microbiome. These results indicate the adverse effects of S-amlodipine on the liver and provide a rich understanding of the safety of long-term S-amlodipine administration.

Background: Hepatic dysfunction (HD) after liver transplantation (LT) or extended hepatic resection (EHR) is associated with graft failure and high short-term mortality. We evaluated the safety and depurative efficacy of CytoSorb® in these settings. The primary endpoint was the change in serum total bilirubin at the end of the treatment compared to the baseline value. The secondary endpoint was to evaluate the trend of serum total bilirubin and coagulation parameters up to 72 h after discontinuation of CytoSorb®. The effects of CytoSorb® therapy on the degree of hepatic encephalopathy (HE), Sequential Organ Failure Assessment (SOFA), and Model for End-Stage Liver Disease (MELD) scores as well as the hemodynamic status compared to baseline were also assessed. Methods: Adult patients with a serum total bilirubin level > 10 mg/dL admitted to the Intensive Care Unit were included. Exclusion criteria were hemodynamic instability, postoperative bleeding and platelet count < 20,000/mm3. Results: Seven patients were treated. Serum total bilirubin was significantly reduced at the end of treatment. However, seventy-two hours after the discontinuation of extracorporeal therapy, bilirubin levels returned to baseline levels in four patients. A decrease in platelet count was found during therapy, and platelet transfusion was required in six cases. A significant increase in D-dimer at the end of treatment was detected. HE degree, SOFA and MELD scores remained stable, while a deterioration in hemodynamic status was observed in two cases. Conclusions: Our preliminary findings did not show the possible benefits of CytoSorb® in rebalancing clinical and laboratory parameters in patients with HD after LT or EHR. [ABSTRACT FROM AUTHOR]

Dengue is the most rapidly emerging climate-sensitive infection, and there has been a 10-fold rise in cases over the past 20 years. Severe illness is characterized by vascular leakage, organ dysfunction, and severe bleeding which occur due to the direct effects of the viral non-structural protein NS1 and an aberrant host immune response. Dengue NS1 antigen, cytokines such as IL-1β, TNF-α, and IL-6, lipid mediators such as platelet-activating factor (PAF), leukotrienes and prostaglandins, VEGF, chymase, tryptase, and MMP-9 are thought to contribute to endothelial dysfunction. Many mechanisms contribute to liver dysfunction, including prolonged shock that causes hypoxic damage, direct liver cell death due to infection with the virus, and immune-mediated effects. Bleeding following dengue virus infection occurs due to multiple mechanisms including platelet activation by NS1, serotonin, and PAF, accompanied by a wide range of other coagulation abnormalities. Dengue is the most rapidly emerging climate-sensitive infection, and morbidity/mortality and disease incidence are rising markedly, leading to healthcare systems being overwhelmed. There are currently no specific treatments for dengue or prognostic markers to identify those who will progress to severe disease. Owing to an increase in the burden of illness and a change in epidemiology, many patients experience severe disease. Our limited understanding of the complex mechanisms of disease pathogenesis has significantly hampered the development of safe and effective treatments, vaccines, and biomarkers. We discuss the molecular mechanisms of dengue pathogenesis, the gaps in our knowledge, and recent advances, as well as the most crucial questions to be answered to enable the development of therapeutics, biomarkers, and vaccines.

Excess adipose tissue, as well as its distribution, correlates strongly with disorders of lipid and liver parameters and chronic inflammation. The pathophysiology of metabolic diseases caused by obesity is associated with the dysfunction of visceral adipose tissue. Effective and alternative interventions such as the Bioenteric Intragastric Balloon and bariatric surgeries such as the Roux-en-Y gastric bypass. The aim of this study was to assess the effect of modifying the recommended standard weight loss diet after bariatric surgery and procedures on reducing chronic inflammation in overweight patients. In the study, bioactive anti-inflammatory dietary components were used supportively. Changes in the concentrations of lipid parameters, liver parameters, antioxidant enzymes, cytokines, and chemokines were demonstrated. The enrichment of the diet, after bariatric surgery, with the addition of n-3 EFAs(Essential Fatty Acids), bioflavonoids, vitamins, and synbiotics resulted in higher weight losses in the patients in the study with a simultaneous reduction in parameters indicating liver dysfunction.

Post-hepatectomy liver failure (PHLF) remains the major contributor to death after liver resection. Oxidative stress is associated with postoperative complications, but its impact on liver function is unclear. This first in-human, prospective, single-center, observational pilot study evaluated perioperative oxidative stress and PHLF according to the ISGLS (International Study Group for Liver Surgery). Serum 8-isoprostane, 4-hydroxynonenal (4-HNE), total antioxidative capacity, vitamins A and E, and intraoperative, sequential hepatic tissue 4-HNE and UCP2 (uncoupling protein 2) immunohistochemistry (IHC) were assessed. The interaction with known risk factors for PHLF and the predictive potential of oxidative stress markers were analyzed. Overall, 52 patients were included (69.2% major liver resection). Thirteen patients (25%) experienced PHLF, a major factor for 90-day mortality (23% vs. 0%; p = 0.013). Post-resection, pro-oxidative 8-isoprostane significantly increased (p = 0.038), while 4-HNE declined immediately (p < 0.001). Antioxidative markers showed patterns of consumption starting post-resection (p < 0.001). Liver tissue oxidative stress increased stepwise from biopsies taken after laparotomy to post-resection in situ liver and resection specimens (all p < 0.001). Cholangiocarcinoma patients demonstrated significantly higher serum and tissue oxidative stress levels at various timepoints, with consistently higher preoperative values in advanced tumor stages. Combining intraoperative, post-resection 4-HNE serum levels and in situ IHC early predicted PHLF with an AUC of 0.855 (63.6% vs. 0%; p < 0.001). This was also associated with grade B/C PHLF (36.4% vs. 0%; p = 0.021) and 90-day mortality (18.2% vs. 0%; p = 0.036). In conclusion, distinct patterns of perioperative oxidative stress levels occur in patients with liver dysfunction. Combining intraoperative serum and liver tissue markers predicts subsequent PHLF. Cholangiocarcinoma patients demonstrated pronounced systemic and hepatic oxidative stress, with increasing levels in advanced tumor stages, thus representing a worthwhile target for future exploratory and therapeutic studies.

Sepsis is a life‐threatening condition that occurs when the body responds to an infection but subsequently triggers widespread inflammation and impaired blood flow. These pathologic responses can rapidly cause multiple organ dysfunction or failure either one by one or simultaneously. The fundamental common mechanisms involved in sepsis‐induced multiple organ dysfunction remain unclear. Here, employing quantitative global and phosphoproteomics, we examine the liver's temporal proteome and phosphoproteome changes after moderate sepsis induced by cecum ligation and puncture. In total, 4593 global proteins and 1186 phosphoproteins according to 3275 phosphosites were identified. To characterize the liver–kidney comorbidity after sepsis, we developed a mathematical model and performed cross‐analyses of liver and kidney proteome data obtained from the same set of mice. Beyond immune response, we showed the commonly disturbed pathways and key regulators of the liver–kidney comorbidity are linked to energy metabolism and consumption. Our data provide open resources to understand the communication between the liver and kidney as they work to fight infection and maintain homeostasis. [ABSTRACT FROM AUTHOR]

Background: We report the case of a patient with melanoma and liver failure with encephalopathy, successfully treated with nivolumab without major side effects and encouraging prolonged disease control. Case presentation: In June 2022, metastatic lesions appeared in the liver associated with melanoma progression under treatment. Liver biopsy was non-diagnostic. The patient developed fever, abdominal distension, and jaundice. Liver function tests (LFTs) began to deteriorate. Hepatic encephalopathy developed in accordance with the worsening liver functions in the patient. Upper abdominal MRI with primovist showed multiple, progressive, metastatic lesions in the liver and mild to moderate dilatation of the intrahepatic biliary tract. Patient was evaluated as acute cholangitis associated with the compression of the biliary tract by progressive liver metastases. In December 2022, the patient was started antibiotherapy for cholangitis and Nivolumab (240 mg flat dose, every 2 weeks) therapy. After the first dose, both LFT and constitutional symptoms began to improve. Subsequently, LFTs almost completely returned to normal, clinical response was achieved. Multiple metastatic lesions in the liver regressed in the radiological evaluation performed at the third month of nivolumab treatment. With partial response, nivolumab treatment is continued. Conclusion: In this case is reported patient with hepatic encephalopathy due to an advanced refractory melanome successfully, and safely, treated with programed cell death-1 (PD-1) inhibitors. Clinical trials to explore the benefits of these immunotherapies in the hepatic failure population with advanced solid tumors should be supported. [ABSTRACT FROM AUTHOR]

Alcohol consumption and metabolic syndrome(MetS), both prevalent in the general population, frequently co-occur. They are recognized as significant contributors to liver dysfunction, yet their combined effect is often challenging to delineate. This study delves into the compounding influence of alcohol consumption and metabolic disorder on liver dysfunction within an elderly demographic in Zhejiang Province, China. Our findings spotlight a heightened risk of liver dysfunction among females, younger individuals, rural dwellers, those with minimal educational attainment, single individuals, and those diagnosed with MetS. We also discerned a positive correlation correlation between the number of MetS components and the propensity for liver dysfunction. Furthermore, the risk of liver dysfunction escalated in tandem with the frequency of alcohol consumption. Interestingly, a prolonged abstinence period (≥ 5 years) seemed to mitigate this risk. Our research underscores the significance of refraining from excessive alcohol consumption, embracing a healthy lifestyle, and managing MetS components-especially triglyceride levels-for effective prevention of liver dysfunction.

Valproic acid (VPA) has been widely used as an antiepileptic drug for decades. Although VPA is effective and well-tolerated, long-term VPA treatment is usually associated with hepatotoxicity. However, the underlying mechanisms of VPAcaused hepatotoxicity remain unclear. In this study, a total of 157 pediatric patients with epilepsy were recruited and divided into normal liver function (NLF, 112 subjects) group and abnormal liver function (ABLF, 45 subjects) group. We observed that MTHFR A1298C and MTHFR C677T variants may be linked to VPA-induced liver dysfunction (p = 0.001; p = 0.023, respectively). We also found that the MTHFR A1298C polymorphism was associated with a higher serum Hcy level (p = 0.001) and a lower FA level (p = 0.001). Moreover, the serum Hcy levels was strongly correlated with the GSH and TBARS concentrations (r = -0.6065, P < 0.001; r = 0.6564, P < 0.001, respectively). Furthermore, logistic analysis indicated that MTHFR A1298C/C677T polymorphisms and increased Hcy concentrations may be risk factors for VPA-induced liver dysfunction. These results suggested that individual susceptibility to VPA-induced liver dysfunction may result from MTHFR A1298C/C677T polymorphisms and increased Hcy levels. This study may be helpful for the prevention and guidance of VPA-induced liver dysfunction. [ABSTRACT FROM AUTHOR]

Background/Aim: Renal dysfunction necessitates S-1 dose reduction. However, decreased dihydropyrimidine dehydrogenase (DPD) activity may lead to adverse events due to 5-FU. The guidelines provided by pharmaceutical companies state that total bilirubin (T-Bil) should be =upper limit of normal (ULN)×1.5 as a reference value for safely taking S-1. Nevertheless, the relationship between the degree of liver dysfunction and S-1 dose reduction has not been clearly established. Patients and Methods: This study focused on patients who received S-1 monotherapy for various types of cancer. The primary outcome was defined as the variation between blood sampling results on the test day and the subsequent test. The variation data were categorized based on the difference in T-Bil: Low T-Bil group (=2.25) and High T-Bil group (>2.25). Results: The number of patients that underwent S-1 monotherapy was 883 and the running number was 7,511; Low T-Bil group included 7,245 and High T-Bil group included 266. Examination of the effect of the T-Bil Group on clinical outcomes revealed a correlation with red blood cell (RBC) count, platelet (PLT) count, and T-Bil level. When the impact of the interaction between the T-Bil Group and any of the clinical outcomes, such as the RBC count, PLT count, and T-Bil level, was determined, each outcome showed a significant decrease in the High T-Bil group compared with the Low T-Bil group. Conclusion: S-1 administration in patients with liver dysfunction accompanied by elevated T-Bil levels may cause thrombocytopenia. [ABSTRACT FROM AUTHOR]

Abstract Background and Aim Abnormal liver biochemistry (ALB) is common among patients with COVID‐19 infection due to various factors. It is uncertain if it persists after the acute infection. We aimed to investigate this. Methods A multicenter study of adult patients hospitalized for COVID‐19 infection, with at least a single abnormal liver function test, was conducted. Detailed laboratory and imaging tests, including transabdominal ultrasound and FibroScan, were performed at assessment and at 6‐month follow‐up after hospital discharge. Results From an initial cohort of 1246 patients who were hospitalized, 731 (58.7%) had ALB. A total of 174/731 patients fulfilled the inclusion criteria with the following characteristics: 48.9% patients had severe COVID‐19; 62.1% had chronic liver disease (CLD); and 56.9% had metabolic‐associated fatty liver disease (MAFLD). ALB was predominantly of a mixed pattern (67.8%). Among those (55.2%) who had liver injury (aspartate aminotransferase/alanine aminotransferase >3 times the upper limit of normal, or alkaline phosphatase/γ‐glutamyl transferase/bilirubin >2 times the upper limit of normal), a mixed pattern was similarly predominant. Approximately 52.3% had normalization of the liver lunction test in the 6‐month period post discharge. Patients with persistent ALB had significantly higher mean body mass index (BMI) and serum low‐density lipoprotein (LDL), higher rates of MAFLD and CLD, higher mean liver stiffness measurement and continuous attenuated parameter score on FibroScan, and higher rates of liver injury on univariate analysis. Multivariate analysis was not statistically significant. Conclusions Approximately 47.7% of COVID‐19 patients were found to have persistent ALB up to 6 months following the acute infection, and it was associated with raised BMI, elevated serum LDL, increased rates of MAFLD and CLD, and higher rates of liver injury on univariate analysis, but not on multivariate analysis.

Background and purposeNutrition is associated with tuberculosis drug-induced liver injury (TBLI). How dietary patterns relate to tuberculosis drug-induced liver injury is still unknown. The objective of this study is to explore the relation between dietary patterns and the risk of tuberculosis drug-induced liver injury.MethodsThis cohort study was conducted at two hospitals in Shandong Province, China, between 2011 and 2013. A total of 605 tuberculosis patients were included in the final analysis. The blood aspartate aminotransferase or alanine aminotransferase level was monitored through the 6-month tuberculosis treatment. The semi-quantitative food frequency questionnaires were used to survey dietary intake in the second month of the tuberculosis treatment. The China Healthy Diet Index (CHDI), which was previously validated in the Chinese population, was used as an a priori dietary pattern. A posteriori dietary patterns were extracted by principal component analysis (PCA).ResultsThe CHDI was negatively associated with the risk of liver injury [adjusted odds ratio (aOR) per standard deviation (SD) (95% CI): 0.61 (0.40–0.94)] and liver dysfunction [aOR per SD (95% CI): 0.47 (0.35–0.64)] in the multivariate logistic model. A positive association between “Organ meat, poultry, and vegetable oil” dietary pattern scores (extracted by PCA) and the risk of liver injury [aOR (95% CI): 3.02 (1.42–6.41)] and liver dysfunction [aOR (95% CI): 1.83 (1.09–3.05)] was observed.ConclusionIn conclusion, a high CHDI score was a protective factor for tuberculosis drug-induced liver injury, while the “Organ meat, poultry, and vegetable oil” dietary pattern, which was rich in organ meat, poultry, and vegetable oil and low in vegetables, was an independent risk factor for tuberculosis drug-induced liver injury.

The liver and thyroid hormones interact at multiple levels to maintain homoeostasis. The liver requires large adequate amounts of thyroid hormones to execute its metabolic functions optimally, and deficiency of thyroid hormones may lead to liver dysfunction. Hypothyroidism has been associated with abnormal lipid metabolism, non-alcoholic fatty liver disease (NAFLD), hypothyroidism-induced myopathy, hypothyroidism-associated gallstones and occasionally, interferon-induced thyroid dysfunction. NAFLD remain an important association with hypothyroidism and further studies are needed that specifically compare the natural course of NAFLD secondary to hypothyroidism and primary NAFLD. Hepatic dysfunction associated with hypothyroidism is usually reverted by normalizing thyroid status. Large scale studies geared towards finding new and effective therapies, especially for NAFLD are needed. The clinician must be aware that there exists overlapping symptomatology between liver dysfunction and severe hypothyroidism which may make delay the diagnosis and treatment of hypothyroidism; this requires a high index of suspicion.

Multiorgan dysfunction is a concern of Fontan patients. To clarify the pathophysiology of Fontan nephropathy, we characterize renal disease in the long-term observational study. Medical records of 128 consecutive Fontan patients [median age: 22 (range 15–37) years old] treated between 2009 and 2018 were reviewed to investigate the incidence of nephropathy and its association with other clinical variables. Thirty-seven patients (29%) showed proteinuria (n = 34) or < 90 mL/min/1.73 m2 of estimated glomerular filtration rate (eGFR) (n = 7), including 4 overlapping cases. Ninety-six patients (75%) had liver dysfunction (Forns index > 4.21). Patients with proteinuria received the Fontan procedure at an older age [78 (26–194) vs. 56 (8–292) months old, p = 0.02] and had a higher cardiac index [3.11 (1.49–6.35) vs. 2.71 (1.40–4.95) L/min/m2, p = 0.02], central venous pressure [12 (7–19) vs. 9 (5–19) mmHg, p < 0.001], and proportion with > 4.21 of Forns index (88% vs. 70%, p = 0.04) than those without proteinuria. The mean renal perfusion pressure was lower in patients with a reduced eGFR than those without it [55 (44–65) vs. 65 (45–102) mmHg, p = 0.03], but no other variables differed significantly. A multivariable analysis revealed that proteinuria was associated with an increased cardiac index (unit odds ratio 2.02, 95% confidence interval 1.12–3.65, p = 0.02). Seven patients with severe proteinuria had a lower oxygen saturation than those with no or mild proteinuria (p = 0.01, 0.03). Proteinuria or a decreased eGFR differentially occurred in approximately 30% of Fontan patients. Suboptimal Fontan circulation may contribute to the development of proteinuria and reduced eGFR.

The current study aimed to investigate the ameliorative effects of Artemisia annua (RA) extract on hepatic toxicity induced by gentamicin injection mice. Sixteen mice were divided into four groups; the control group received saline, the second group received 1% A. annua (RA) extract, third group injected 80 mg/kg gentamicin (GEN) intraperitoneally. The protective group treated with a combination of GEN and A. annua. All mice were treated for consecutive 15 days. Results confirmed that hepatic biomarkers (GPT, GCT, GOT, IL-6 and IL-1β), all were altered after gentamycin injection. The histological analysis confirmed that gentamycin injected mice showed portal vein congestion, micro and macro steatosis, and nuclear pyknosis of hepatocytes. The protective group showed intact central vein with less microsteatosis of some hepatocytes. Immunochemistry analysis confirmed that the immunoreactivity of COX-2 gene showed negative impact in examined groups. Unlike, NF-κB gene exhibited diffuse positive expression in the gentamicin group. TGF-β1 immunoreactivity was mild positive in control and highly upregulated in gentamicin treated mice, all were normalized after RA administration. In conclusion, RA showed a beneficial impact against gentamycin induced hepatic toxicity at cellular and biochemical levels by regulating proteins and inflammatory markers associated with liver activity.

Introduction: The application of voriconazole in patients with liver dysfunction lacks pharmacokinetic data. In previous study, we proposed to develop voriconazole dosing regimens for these patients according to their total bilirubin, but the regimens are based on Monte Carlo simulation and has not been further verified in clinical practice. Besides, there are few reported factors that significantly affect the efficacy of voriconazole. Methods: We collected the information of patients with liver dysfunction hospitalized in our hospital from January 2018 to May 2022 retrospectively, including their baseline information and laboratory data. We mainly evaluated the efficacy of voriconazole and the target attainment of voriconazole trough concentration. Results: A total of 157 patients with liver dysfunction were included, from whom 145 initial and 139 final voriconazole trough concentrations were measured. 60.5% (95/157) of patients experienced the adjustment of dose or frequency. The initial voriconazole trough concentrations were significantly higher than the final (mean, 4.47 versus 3.90 μg/mL, p = 0.0297). Furthermore, daily dose, direct bilirubin, lymphocyte counts and percentage, platelet, blood urea nitrogen and creatinine seven covariates were identified as the factors significantly affect the voriconazole trough concentration. Binary logistic regression analysis revealed that the lymphocyte percentage significantly affected the efficacy of voriconazole (OR 1.138, 95% CI 1.016–1.273), which was further validated by the receiver operating characteristic curve. Conclusion: The significant variation in voriconazole trough concentrations observed in patients with liver dysfunction necessitates caution when prescribing this drug. Clinicians should consider the identified factors, particularly lymphocyte percentage, when dosing voriconazole in this population. [ABSTRACT FROM AUTHOR]

The aim of this study was to ascertain patient characteristics, outcomes, and liver injuries in patients infected with different SARS-CoV-2 variants. Data from consecutive adult patients with severe/critical COVID-19 admitted to our hospital during the peak month of the Delta wave were compared to the ancestral, Alpha, and Omicron waves. The dataset of 551 hospitalized patients was similar in the Delta/non-Delta waves. At admission and discharge, the median aminotransferase levels were normal or slightly increased. During the Delta wave (172 vs. 379 non-Delta patients), more patients died (OR 1.69, 95%CI 1.09–2.56) or had liver injury at discharge (alanine aminotransferase, ALT ≥ 2 ULN) (OR 1.97, 95%CI 1.08–3.54). In-hospital mortality was associated with age, lung injury, intensive care unit admission, number of and cardiovascular comorbidities, diabetes, chronic kidney disease, and all inflammatory biomarkers. Serious liver injury at admission (ALT ≥ 5 × ULN) was significantly associated with in-hospital mortality (OR = 7.9, 95%CI 2–28.9). At discharge, drug-induced liver injury (DILI) was found in patients treated with remdesivir, ALT ≥ 2 ULN (OR = 2.62, 95%CI 1.22–5.75). Treatment with dexamethasone, remdesivir, and immunomodulators showed improved survival, OR = 0.50 (95%CI 0.33–0.77). Regardless of the variant and treatment options, less than 2% of patients displayed serious liver injury, which was not found to be a death predictor in multivariable analysis.

Background/Aim: Eribulin is an effective chemotherapeutic agent for advanced and metastatic breast cancer. However, severe neutropenia occurs in 30-40% of patients and interferes with the recommended treatment schedule. Neutropenia is a major cause of treatment interruptions, delays, or even relative dose reductions. This study aimed to examine the risk factors for severe neutropenia after eribulin treatment. Patients and Methods: We retrospectively evaluated 263 patients with metastatic breast cancer who had received eribulin therapy. Risk factors for severe neutropenia in the first cycle were evaluated. Results: Severe neutropenia in cycle 1 occurred in 50% of the patients. Multivariate analysis suggested six risk factors for severe neutropenia: low baseline neutrophil count and body mass index, high aspartate aminotransferase and bilirubin levels, creatinine clearance (CrCl) less than 50 ml/min, and eribulin dose of 1.4 mg/m². Conclusion: This is one of the few studies to simultaneously examine both hepatic and renal functions in relation to severe neutropenia induced by eribulin. We have provided important information to support the close monitoring of patients with these risk factors and subsequent dosage adjustments, if necessary. [ABSTRACT FROM AUTHOR]

Background: Post-hepatectomy liver failure (PHLF) is a common complication in patients with liver cancer. Biomarker-based methods, such as the Fibrosis-4 (FIB-4) index, can potentially reduce PHLF through identification and risk mitigation in high-risk patients. We conducted a systematic review to summarize the literature around the use of the FIB-4 index for predicting PHLF in liver cancer patients. Methods: We searched PubMed and Scopus (1 January 2010 - 31 December 2022) to identify the pertinent literature. We used predefined eligibility criteria to select studies for inclusion in our review. Information on study characteristics, FIB-4 index prognostic utility (sensitivity, specificity, predictive values, Area Under Curve -- AUC), and comparisons with other liver function tests was collected for each included study. Study quality was assessed with the QUIPS checklist. Basic descriptive statistics were used to analyse the data obtained from included studies. Results: We identified 6 published studies for our review. Most studies were from China (5/6, 83.3%), and sample sizes ranged from 140-1353 patients. All studies were assessed to have had a low risk of bias. FIB-4 had a reported sensitivity for PHLF of 65.2-75% and a reported specificity for PHLF of 83.3-93%. The AUCs reported for FIB-4 when used to predict PHLF ranged from 0.647 to 0.758. The prognostic utility of the FIB-4 index was generally comparable to other more complex liver function tests. Conclusion: The FIB-4 index appears to be a promising, non-invasive method for predicting PHLF in patients with liver cancer, warranting further research on this biomarker-based index.

Critically ill patients are at risk of developing acute liver dysfunction as part of multiorgan failure sequelae. Clearing the blood from toxic liver-related metabolites and cytokines could prevent further organ damage. Despite the increasing use of hemoadsorption for this purpose, evidence of its efficacy is lacking. Therefore, we conducted this systematic review and meta-analysis to assess the evidence on clinical outcomes following hemoadsorption therapy. A systematic search conducted in six electronic databases (PROSPERO registration: CRD42022286213) yielded 30 eligible publications between 2011 and 2023, reporting the use of hemoadsorption for a total of 335 patients presenting with liver dysfunction related to acute critical illness. Of those, 26 are case presentations (n = 84), 3 are observational studies (n = 142), and 1 is a registry analysis (n = 109). Analysis of data from individual cases showed a significant reduction in levels of aspartate transaminase (p = 0.03) and vasopressor need (p = 0.03) and a tendency to lower levels of total bilirubin, alanine transaminase, C-reactive protein, and creatinine. Pooled data showed a significant reduction in total bilirubin (mean difference of −4.79 mg/dL (95% CI: −6.25; −3.33), p = 0.002). The use of hemoadsorption for critically ill patients with acute liver dysfunction or failure seems to be safe and yields a trend towards improved liver function after therapy, but more high-quality evidence is crucially needed.

Aims: Polymyxin B (PMB) is widely used to treat infections caused by multidrug‐resistant Gram‐negative pathogens. Currently, the pharmacokinetic data of PMB in patients with liver dysfunction are limited. This study aimed to develop a population pharmacokinetic (PopPK) model of PMB in patients with liver dysfunction and identify the factors affecting PMB pharmacokinetics. Methods: We conducted a retrospective pharmacokinetic study involving 136 adults with different levels of liver function. Nonlinear mixed effects modelling was used to develop a PopPK model of PMB. Monte Carlo simulation was used to design PMB dosage schedules across various liver and renal functions. Results: PMB pharmacokinetic analyses included 401 steady‐state concentrations in 136 adult patients. A one‐compartment pharmacokinetic model with first‐order absorption and elimination was used to describe the data. The typical population value of PMB clearance was 2.43 L/h and the volume of distribution was 23.11 L. This study revealed that creatinine clearance (CrCL) and Child–Pugh class were significantly associated with PMB pharmacokinetic parameters; however, clinically relevant variations of dose‐normalized drug exposure were not significant. For patients with a minimum inhibitory concentration of ≤0.5 mg/L, the appropriate dose was 40–75 mg/12‐h. When the dose exceeded 100 mg/12‐h, the risk of nephrotoxicity increased significantly. Conclusions: This study provided PMB pharmacokinetic information for patients with liver dysfunction. Patients with renal and liver dysfunctions may not require an initial dose adjustment. Rather than PopPK‐guided dose adjustment, therapeutic drug monitoring of PMB plays a more direct role in optimizing dosing regimens based on its therapeutic window. [ABSTRACT FROM AUTHOR]

Background: The advent of direct‐acting antivirals has helped to increase the safe utilization of organs from hepatitis C virus positive (HCV+) donors. However, the outcomes of heart transplantation (HT) using an HCV+ donor are unclear in recipients with underlying liver disease represented by an elevated model for end‐stage liver disease excluding international normalized ratio (MELD‐XI). Methods: The United Network of Organ Sharing database was queried from Jan 2016 to Dec 2021. Post‐transplant outcomes stratified by recipient MELD‐XI score (low <10.37, medium, 10.38–13.39, and high >13.4) was compared between patients with HT from HCV+ (N = 792) and patients with HT from HCV‐negative donors (N = 15,266). Results: The median MELD‐XI score was comparable (HCV+, 12.1, vs. HCV‐negative, 11.8, p =.37). In the HCV+ group, donors were older (33 vs. 31 years, p <.001). Ischemic time of donor hearts (3.48 vs. 3.28 h, p <.001) and travel distance (250 vs. 157 miles, p <.001) were longer in HCV+ group. In the Kaplan Meier analysis with a median follow‐up of 750 days, survival was comparable between the two groups (2‐year survival, MELD‐XI Low: HCV+, 92.4 ± 3.6% vs. HCV‐negative, 91.1 ±.8%, p =.83, Medium: HCV+ 89.2 ± 4.3% vs. HCV‐negative, 88.2 ± 1.0%, p =.68, and High: HCV+, 84.9 ± 4.5% vs. HCV‐negative, 84.6 ± 1.1%, p =.75) In multivariate Cox hazard models, HCV donors were not associated with mortality in each MELD‐XI subgroup (Low: adjusted hazard ratio (aHR), 1.02, p =.94; Medium: aHR,.95, p =.81; and High: aHR,.93, p =.68). Conclusion: Utilization of HCV+ hearts was not associated with an increased risk of adverse outcomes in recipients with an elevated MELD‐ XI score. [ABSTRACT FROM AUTHOR]

Background and Objectives: Macronutrients play a vital role in liver dysfunction and affect tuberculosis treatment and prognosis. However, macronutrients intake was inadequate for most tuberculosis patients. This study aimed to clarify the associations between macronutrients intake or energy percentages and liver dysfunction in tuberculosis patients. Methods and Study Design: In this cross-sectional study, 2581 active tuberculosis patients aged =18 years were included from local tuberculosis clinics in Linyi, China. Macronutrients intake and energy percentages were assessed by 24-hour dietary recalls. The concentration of alanine transferase (ALT) or aspartate transaminase (AST) greater than 40 U/L was defined as liver dysfunction. A restricted cubic spline (RCS) was applied to determine the dose-response relationships. Results: Liver dysfunction was assessed for 14.6% (377 patients) of tuberculosis patients. Higher protein (Q2-Q4 in model 1 and 2) or fat intake and fat-to-energy percentages and lower carbohydrate-to-energy percentages (Q4 in model 1) were associated with a decreased incidence of liver dysfunction (p-trend < 0.05). Among those who were male, normal BMI, or consumed energy <1636 kcal/d, inverse associations between protein or fat intake and the risks of liver dysfunction in models were suggested (ptrend < 0.05). Moreover, J-shaped curves in RCS were evident in liver dysfunction tuberculosis patients with protein or fat intake (p-nonlinearity < 0.05). Conclusions: Significant linear associations between macronutrients intake or energy percentages and liver dysfunction prevalence were found only in male, normal BMI, or less energy intake patients. The shapes of liver dysfunction-morbidity differed significantly by macronutrients intake or energy percentage. [ABSTRACT FROM AUTHOR]

The disease sepsis is caused by an infection that damages organs. Liver injury, with ferroptosis playing a key role, is an early sign of sepsis. G protein-coupled receptor 116 (GPR116) is essential in the maintenance of functional homeostasis in various systems of the body and has been proven to play a protective role in septic lung injury. However, it's role in septic liver injury remains unclear. In this study, we found that hepatic ferroptosis during sepsis was accompanied by GPR116 upregulation. Hepatocyte-specific GPR116 gene deletion can prevent hepatic ferroptosis, thereby alleviating sepsis-induced liver dysfunction and improving mouse survival, which was verified in vivo. Mechanistically, GPR116 aggravated mitochondrial damage and lipid peroxidation in hepatocytes by inhibiting system Xc–/GSH/GPX4 in overexpression experiments. In conclusion, we have identified GPR116 as a vital mediator of ferroptosis in sepsis-induced liver injury. It is thus an attractive therapeutic target in sepsis. [ABSTRACT FROM AUTHOR]

Preeclampsia and decompensated chronic liver disease are known triggers of acute hepatic dysfunction in pregnancy, rarely including hepatic encephalopathy. Differentiating the driver of acute hepatic dysfunction in patients with concomitant preeclampsia and preexisting liver disease presents a diagnostic challenge with important management implications.A 42-year-old woman, gravida 3 para 0201, at 24 1/7 weeks of gestation presented with hepatic encephalopathy, transaminitis, and hyperbilirubinemia in the setting of cirrhosis and severe new-onset preeclampsia. The preeclampsia was thought to be the leading etiology of hepatic encephalopathy, prompting emergent Cesarean delivery at 24 2/7 weeks. Hepatic encephalopathy, blood pressure, and laboratory derangements improved promptly post-delivery.Preeclampsia can trigger acute hepatic dysfunction, including hepatic encephalopathy, in the setting of previously compensated preexisting liver disease. Recognizing this association has important implications for management and treatment.

Liver and heart disease are major causes of death worldwide. It is known that metabolic alteration causing type 2 diabetes (T2D) and Nonalcoholic fatty liver (NAFLD) coupled with a derangement in lipid homeostasis, may exacerbate hepatic and cardiovascular diseases. Some pharmacological treatments can mitigate organ dysfunctions but the important side effects limit their efficacy leading often to deterioration of the tissues. It needs to develop new personalized treatment approaches and recent progresses of engineered RNA molecules are becoming increasingly viable as alternative treatments. This review outlines the current use of antisense oligonucleotides (ASOs), RNA interference (RNAi) and RNA genome editing as treatment for rare metabolic disorders. However, the potential for small non-coding RNAs to serve as therapeutic agents for liver and heart diseases is yet to be fully explored. Although miRNAs are recognized as biomarkers for many diseases, they are also capable of serving as drugs for medical intervention; several clinical trials are testing miRNAs as therapeutics for type 2 diabetes, nonalcoholic fatty liver as well as cardiac diseases. Recent advances in RNA-based therapeutics may potentially facilitate a novel application of miRNAs as agents and as druggable targets. In this work, we sought to summarize the advancement and advantages of miRNA selective therapy when compared to conventional drugs. In particular, we sought to emphasise druggable miRNAs, over ASOs or other RNA therapeutics or conventional drugs. Finally, we sought to address research questions related to efficacy, side-effects, and range of use of RNA therapeutics. Additionally, we covered hurdles and examined recent advances in the use of miRNA-based RNA therapy in metabolic disorders such as diabetes, liver, and heart diseases.

Abstract Background Anorexia nervosa (AN) is frequently associated with liver dysfunction, but the precise mechanism remains undefined. Since the nutritional marker albumin has a low correlation with changes in body weight in AN, and patients with AN often have dehydration as a complication, we also examined whether haematocrit (HCT)-adjusted serum albumin could be a better nutritional marker in AN. Case presentation We describe a 15-year-old girl with severe weight loss and liver damage whose liver enzymes normalized after 1.5 months of hospitalization and weight gain. We found a significant correlation between body weight (BW) and HCT-adjusted serum albumin (Spearman’s rank correlation coefficient (rs) = 0.66, P = 5.28 × 10−3) and between BW and alanine aminotransferase (ALT) (rs = -0.825, P = 8.45 × 10−5). After division by HCT, correlations between serum albumin and ALT (rs = -0.835, P = 5.24 × 10−5) and between the iron-storage protein ferritin and the liver enzyme gamma-glutamyl transferase (rs = 1.0, P = 0.017) were also statistically significant. Conclusion These results suggest that improvement of the nutritional status in AN could relieve liver dysfunction and facilitate iron transport. Since a decrease in the iron-transport protein transferrin presumably increases labile non-transferrin-bound iron, resulting in excess reactive oxygen species production, a defect in iron transport due to malnutrition could be one of the causes of liver injury in AN. In addition, HCT-adjusted albumin could be a better marker than its raw data to assess changes in nutritional status in AN.
