AIM: Myostatin is a myokine involved in muscle mass regulation. The associations between circulating myostatin levels and clinical characteristics in patients with acute liver failure (ALF) and late-onset hepatic failure (LOHF) are unclear. METHODS: In this retrospective study, 51 patients with ALF or LOHF were included. Serum myostatin was measured using an enzyme-linked immunosorbent assay. RESULTS: Myostatin levels were significantly lower in patients with ALF and LOHF than in controls (ALF/LOHF: 2522 pg/mL, controls: 3853 pg/mL, p = 0...

INTRODUCTION: Autoimmune hepatitis (AIH) is a chronic, progressive liver disease which, in most cases, may require lifelong immunosuppression. Hepatitis E virus (HEV) is a leading cause of acute, typically self-limited, hepatitis worldwide, although immunocompromised patients may develop chronic hepatitis. OBJECTIVES: Here, we evaluated the impact of HEV seropositivity on the clinical course of AIH. PATIENTS AND METHODS: A group of 374 adult patients with AIH (female 68%, age 34 (18-83) years, 38% with liver cirrhosis) was analyzed...

BACKGROUND: Malnutrition, despite being a common complication, is often neglected in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). The objective of this study was to develop a simplified nutritional prognostic score to accurately predict mortality in HBV-ACLF patients. METHODS: In this multicenter retrospective study, clinical data from 530 HBV-ACLF patients were used to create a new prognostic score, which was then validated in two external cohorts ( n = 229 and 248)...

In the last 10 years, the care of patients with cystic fibrosis (CF) has been revolutionized with the introduction of cystic fibrosis transmembrane conductance regulator (CFTR) modulator drugs, with a major impact on symptoms and life expectancy, especially considering the newest and highly effective elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) therapy. Conversely, adverse effects are relatively frequent, with some being life-threatening, such as severe hepatitis. Clinical trials on children starting CFTR modulators have reported transaminase elevations >3× upper limit of the norm in 10%-20% of patients, whereas real-life studies have reported discontinuation rates three times higher than those observed in phase 3 trials...

Oxidative injury is concerned with the pathogenesis of several liver injuries, including those from acute liver failure to cirrhosis. This study was designed to explore the antioxidant activity of Bacopa monnieri (BM) on Aflatoxin B1 (AFB1) induced oxidative damage in Wistar albino rats. Aflatoxin B1 treatment (200 μg/kg/day, p.o.) for 28 days induced oxidative injury by a significant alteration in serum liver function test marker enzymes (AST, ALT, ALP, LDH, albumin and bilirubin), inflammatory cytokines (IL-6, IL-10 and TNF-α), thiobarbituric acid reactive substances (TBARS) along with reduction of antioxidant enzymes (GSH, SOD, CAT), GSH cycle enzymes and drug-metabolizing enzymes (AH and AND)...

Inorganic arsenic is a well-established environmental toxicant linked to acute liver injury, fibrosis, and cancer. While oxidative stress, pyroptosis, and ferroptosis are known contributors, the role of PTEN-induced kinase 1 (PINK1)-mediated mitophagy in arsenic-induced hepatic immunotoxicity remains underexplored. Our study revealed that acute arsenic exposure prompts differentiation of hepatic dendritic cells (DCs) and T helper (Th) 1, Th2, Th17, and regulatory T (Treg) cells, alongside increased transcription factors and cytokines...

DESIGN: This study is a randomised, placebo-controlled, triple-arm, phase IIA clinical trial with double masking which investigates the effectiveness and safety of Cannabidiol (CBD) as an analgesic for acute dental pain. The intervention drug, Epidiolex is an FDA-approved CBD oral solution (100 mg/ml) derived from the cannabis plant. The psychoactive ingredient tetrahydrocannabinol (THC) is not included. The maximum recommended daily dose of Epidiolex is 20 mg/kg. 64 patients with moderate-severe odontogenic pain participated in the study and REDCap software was utilised to randomly assign participants into groups: CBD10 (10 mg/kg), CBD20 (20 mg/kg) and placebo...

Acute liver failure (ALF) is a deadly illness due to insufficient detoxification in liver induced by drugs, toxins, and other etiologies, and the effective treatment for ALF is very limited. Among the drug-induced ALF, acetaminophen (APAP) overdose is the most common cause. However, the molecular mechanisms underlying APAP hepatoxicity remain incompletely understood. Sirtuin 6 (Sirt6) is a stress responsive protein deacetylase and plays an important role in regulation of DNA repair, genomic stability, oxidative stress, and inflammation...

Over the course of the past six decades, liver transplantation has evolved to become the treatment of choice for chronic end-stage liver disease and some cases of acute hepatic failure. Currently, more than 34,000 liver transplants are conducted worldwide per annum, and overall one year survival rates exceed 90%. However, the early years of human liver transplantation were beset by failure. Eyewitness reports from this period make for tragic, yet compelling reading. Volume 12 of The History of Anaesthesia Society Proceedings contains one such account, written by Dr Elizabeth Gibbs...

The concept of structural kidney damage and renal dysfunction as a result of jaundice attracted attention in the medical community in the early and mid-20th century. The postulated doctrine of the time was that the excretion of elevated concentrations of bile results in bile-stained casts occupying collecting and distal convoluted tubules, degeneration of tubular epithelium, and decreased renal function. Compared to the hepatorenal syndrome, the poster child of hepatology and nephrology collaboration, the notion of structural kidney damage and renal dysfunction as a result of cholemia lost its traction and has almost disappeared from modern textbooks...

N,N-dimethylformamide (DMF) is a widely utilized chemical solvent with various industrial applications. Previous studies have indicated that the liver is the most susceptible target to DMF exposure, whereas the underlying mechanisms remain to be elucidated. This study aimed to investigate the role of NLRP3 inflammasome in DMF-induced liver injury in mice by using two NLRP3 inflammasome inhibitors, Nlrp3-/- mice, Nfe2l2-/- mice, and a macrophage-depleting agent. RNA sequencing revealed that endoplasmic reticulum (ER) stress and NLRP3 inflammasome-associated pathways were activated in the mouse liver after acute DMF exposure, which was validated by Western blotting...

BACKGROUND OBJECTIVES: Bangladesh is afflicted with periodic dengue outbreak every few years and one of the worst upsurges was recorded in 2019 during which there was an increasing trend of dengue with unusual symptoms which were not so common before. This study aims to describe the experience of three tertiary care centres of Dhaka regarding the clinical and laboratory, hospital outcome and management profile of the Expanded Dengue Syndrome (EDS) cases admitted from the 2019 outbreak...

Aflatoxin B1 (AFB1 ) is extremely hepatotoxic, a causative agent of liver cancer, and can cause symptoms of acute or chronic liver damage. Chito-oligosaccharides (COS), obtained from the degradation of chitosan derived from shrimp and crab shells, is a natural antioxidant substance and its antitumor properties have been widely studied, but less research has been done on the prevention of AFB1 -induced acute liver injury. In this study, rats were acutely exposed to 1 mg/kg BW AFB1 and simultaneously gavaged with different doses of COS for 8 days...

Hematopoietic stem cell transplantation (HSCT) can cure malignant and nonmalignant hematological disorders. From 1983 to 2022, Taiwan performed more than 10,000 HSCT transplants. The Taiwan Blood and Marrow Transplantation Registry collects clinical information to gather everyone's experience and promote the advances of HSCT in Taiwan to gather everyone's experience and promote advances of HSCT in Taiwan. Compared with matched sibling donors, transplants from matched unrelated donors exhibited a trend of superior survival...

Background Hepatitis C virus (HCV) coinfection may further compromise immunological and cognitive function in people with HIV (PWH). This study compared laboratory and neuropsychiatric measures across the periods of HCV seroconversion and direct-acting antiviral (DAA) therapy with sustained virologic response (SVR) among PWH who initiated antiretroviral therapy (ART) during acute HIV infection (AHI) and acquired HCV after 24 weeks of ART. Methods Participants from the RV254 AHI cohort underwent paired laboratory and neuropsychiatric assessments during regular follow-up...

BACKGROUND: Acute hepatic porphyrias (AHPs) are a group of rare diseases that encompasses acute intermittent porphyria, variegate porphyria, hereditary coproporphyria, and 5-aminolaevulinic acid dehydratase deficiency porphyria. Symptoms of AHP are nonspecific which, together with its low prevalence, difficult the diagnosis and follow-up of these patients. MATERIAL AND METHODS: This project used DELPHI methodology to answer PICO questions related to management of patients with AHPs...

Immune thrombocytopenic purpura (ITP) is a hematologic condition characterized by decreased circulating platelets, resulting in bruising, bleeding gums, and internal bleeding. This disorder can be categorized into two primary forms based on the duration of symptoms and underlying causes. Acute ITP primarily affects young children, typically between the ages of two and six, but it can also impact older children and adults. Viral infections like chickenpox, respiratory infections, or gastroenteritis often precede it...

Intrahepatic cholestasis of pregnancy is an intrahepatic etiology of acute cholestasis commonly defined by pruritus and increased bile acids, liver transaminases, and, occasionally, bilirubin. Azathioprine is an immunosuppressive agent associated with various forms of hepatoxicity, ranging from transient rises in serum aminotransferase levels, acute cholestatic injury, and chronic hepatic injury. In this report, we present a 20-year-old pregnant woman who presented with cholestatic liver injury due to intrahepatic cholestasis of pregnancy with a clinical picture complicated by increased levels of azathioprine metabolites...

BACKGROUND: The current study uniquely focuses on the global incidence and temporal trends of acute hepatitis C (AHC) and hepatitis C virus (HCV)-related cirrhosis among women of reproductive age (15-49 years) from 1990-2019. The risk of vertical transmission and adverse perinatal outcomes associated with HCV infection underscores the importance of prioritising these women in HCV prevention efforts. METHODS: Leveraging the Global Burden of Disease 2019 data, we calculated age-standardised incidence rates (ASIR) and assessed temporal trends via the average annual percent change from joinpoint regression...

Phosphatidylinositol 3-kinase (PI3K) is one of the most attractive therapeutic targets for cervical cancer treatment. In this study, we designed and synthesized a series of benzimidazole derivatives and evaluated their anti-cervical cancer activity. Compound 4r exhibited strong antiproliferative activity in different cervical cancer cell lines HeLa, SiHa and Ca Ski, and relative lower cytotoxicity to normal hepatic and renal cell lines LO2 and HEK-293t (IC50 values were at 21.08 μM and 23.96 μM respectively)...
