Drug induced liver disease

BACKGROUND: Tuberculosis (TB) is one of the oldest and most well-known diseases that has been associated with humans for many years and remains a global health challenge today. Timely diagnosis and proper treatment are crucial for controlling and preventing the spread of the disease. While anti-TB drugs offer many benefits, inadequate monitoring can lead to a range of side effects, including hepatotoxicity, which is a major concern and can cause treatment discontinuation. The aim of this study was to determine the approach to the hepatotoxicity of anti-TB drugs and to investigate potential relationships between demographic factors, underlying medical conditions, and successful retreatment outcomes for hepatotoxicity induced by anti-TB drugs...

Greater celandine ( Chelidonium majus ) leaf extracts have been used for centuries as a natural remedy for various gastrointestinal symptoms. Greater celandine is associated with several case reports of hepatotoxicity, mainly from Europe. No cases from the United States have been identified. We present a case of acute hepatitis from greater celandine in the United States in a 72-year-old man taking this herbal supplement for nausea. In patients presenting with acute liver injury, gastroenterologists should be aware of this herb and reminded to assess for herbal and dietary supplement hepatotoxicity, especially in those remedies used to treat common gastrointestinal symptoms...

Sorafenib, a kinase inhibitor, is known to cause skin toxicity, which sometimes leads to treatment interruption or drug dose reduction. Erythema multiforme (EM) is one of these dermatologic toxicities induced by sorafenib. We report the case of a 28-year-old male with hepatocellular carcinoma (HCC). Two months after surgery, the patient presented with multiple metastases to the retroperitoneal lymph nodes and lungs. Therefore, systemic therapy with sorafenib was indicated. While receiving the medication, the patient presented signs compatible with EM...

Cisplatin (CP) is a chemotherapy drug widely prescribed to treat various neoplasms. Although fundamental for the therapeutic action of the drug, its cytotoxic mechanisms trigger adverse effects in several tissues, such as the kidney, liver, and heart, which limit its clinical use. In this sense, studies point to an essential role of damage to nuclear and mitochondrial DNA associated with oxidative stress, inflammation, and apoptosis in the pathophysiology of tissue injuries. Due to the limitation of effective preventive and therapeutic measures against CP-induced toxicity, new strategies with potential cytoprotective effects have been studied...

We have previously reported the total synthesis and structure-activity relationships (SAR) of 2-prenylated benzopyrans with PPAR agonist activity. Herein, we have described the synthesis and PPAR activity of 2-prenylated benzopyrans and 2-prenylated quinolines. The benzopyran nucleus was generated via enamine-catalyzed Kabbe condensation, and the quinoline nucleus via Friedländer condensation. Results demonstrated that both benzopyran (5a) and quinoline (4b) derivatives bearing a γ,δ-unsaturated ester displayed a pan-PPAR agonism...

BACKGROUND: Autoimmune hepatitis (AIH) is an immune-mediated hepatic disease associated with intense complications. AIH is more common in females and needs effective drugs to treat. Guizhi Fuling Wan (GZFLW) is a traditional Chinese herbal formula used to treat various gynecologic diseases. In this study, we aim to extend the new use of GZFLW for AIH. METHODS: The tandem MS-based analysis was used to identify secondary metabolites in GZFLW. Therapeutic effects of GZFLW were tested in a concanavalin A (Con A)-induced AIH model in mice...

INTRODUCTION AND IMPORTANCE: Arteriovenous malformations (AVMs) in the liver caused by hereditary hemorrhagic telangiectasia (HHT) influence pulmonary artery hypertension (PAH). Liver transplantation (LT) is the most common treatment for HHT-induced hepatic AVMs. However, LT is contraindicated for patients with severe PAH. There is controversy regarding the ideal therapeutic approach for HHT with PAH and hepatic AVMs. CASE PRESENTATION: We present the case of a 48-year-old female with PAH and HHT...

BACKGROUND AND OBJECTIVES: Acute liver failure (ALF) is an uncommon but potentially dramatic syndrome characterized by massive hepatic necrosis and has a very high mortality rate of 50% to 75% without liver transplantation. This study is aimed at analyzing the etiological spectrum of ALF patients and compare these with ALF mimics such as malaria, dengue fever and other tropical infectious diseases. METHODS: The study population included patients who presented with ALF and ALF mimics in a tertiary care center over two years...

Methotrexate (MTX) is the first drug of choice to treat several diseases, including rheumatoid arthritis. However, its administration is accompanied by severe side effects, most commonly hepatotoxicity. Hence, alternative therapies with a lower toxicity and fewer side effects are needed. This study aimed to investigate the antioxidant and hepatoprotective effects of silibinin (SIL, natural agent) against MTX-induced hepatotoxicity in an adjuvant-induced arthritis (AIA) rat model. Arthritic rats were treated with SIL (100 mg/kg) and/or methotrexate (2 mg/kg)...

Metabolic dysfunction-associated steatotic liver disease (MASLD) is not only related to traditional cardiovascular risk factors like type 2 diabetes mellitus and obesity, but it is also an independent risk factor for the development of cardiovascular disease. MASLD has been shown to be independently related to endothelial dysfunction and atherosclerosis. MASLD is characterized by a chronic proinflammatory response that, in turn, may induce a prothrombotic state. Several mechanisms such as endothelial and platelet dysfunction, changes in the coagulative factors, lower fibrinolytic activity can contribute to induce the prothrombotic state...

Rett Syndrome (RTT) is a progressive X-linked neurodevelopmental disorder with no cure. RTT patients show disease-associated symptoms within 18 months of age that include developmental regression, progressive loss of useful hand movements, and breathing difficulties, along with neurological impairments, seizures, tremor, and mental disability. Rett Syndrome is also associated with metabolic abnormalities, and the anti-diabetic drug metformin is suggested to be a potential drug of choice with low or no side-effects...

BACKGROUND & AIM: Telocytes, a recently identified type of sub-epithelial interstitial cell, have garnered attention for their potential roles in tissue homeostasis and repair. However, their contribution to gastric metaplasia remains unexplored. This study aimed to elucidate the role of telocytes in the development of metaplasia within the gastric environment. METHODS: To investigate the presence and behavior of telocytes during metaplastic transitions, we utilized both drug-induced acute injury models (using DMP-777 or L635) and a genetically engineered mouse model (Mist1-Kras)...

BACKGROUND & AIMS: The precise pathomechanisms underlying the development of nonalcoholic steatohepatitis (NASH, also known as metabolic dysfunction-associated steatohepatitis [MASH]) remain incompletely understood. This study investigates the potential role of EF-hand domain family member D2 (EFHD2), a novel molecule specific to immune cells, in NASH pathogenesis. METHODS: Hepatic EFHD2 expression was characterized in NASH patients and two diet-induced NASH mouse models...

Anti-tuberculosis drug-induced liver injury (ADLI) is a common adverse reaction during anti-tuberculosis treatment and often leads to treatment interruptions. Circular RNAs (circRNAs) have been identified as key modulators in liver diseases. CircRNAs is a special class of noncoding RNAs that have been found to have significant impacts on the progression of inflammation via various mechanisms. In the serum of ADLI patients, upregulation of the circular RNA hsa_circ_0082152 (derived from the host gene snd1) was observed, along with increased ALT and AST levels, as well as alterations in the levels of inflammation-related factors such as NF-κB, IL-1β and TNF-α...

Liver fibrosis is a common pathological feature of most chronic liver diseases with no effective drugs available. Phosphodiesterase 1 (PDE1), a subfamily of the PDE super enzyme, might work as a potent target for liver fibrosis by regulating the concentration of cAMP and cGMP. However, there are few PDE1 selective inhibitors, and none has been investigated for liver fibrosis treatment yet. Herein, compound AG-205/1186117 with the dihydropyrimidine scaffold was selected as the hit by virtual screening. A hit-to-lead structural modification led to a series of dihydropyrimidine derivatives...

Algae are used as safe materials to fabricate novel nanoparticles to treat some diseases. Marine brown alga Sargassum vulgare are used to fabricate silver nanoparticles (Sv/Ag-NPs). The characterization of Sv/Ag-NPs was determined by TEM, EDX, Zeta potential, XRD, and UV spectroscopy. The Sv/Ag-NPs were investigated as antioxidant, anticancer, and antibacterial activities against Gram-positive bacteria Bacillus mojavensis PP400982, Staphylococcus caprae PP401704, Staphylococcus capitis PP402689, and Staphylococcus epidermidis PP403851...

A hepatocyte cell line was used to determine the hepatotoxicity of sedatives and opioids, as the hepatotoxicity of these drugs has not yet been well characterized. This might pose a threat, especially to critically ill patients, as they often receive high cumulative doses for daily analgosedation and often already have impaired liver function due to an underlying disease or complications during treatment. A well-established biosensor based on HepG2/C3A cells was used for the determination of the hepatotoxicity of commonly used sedatives and opioids in the intensive care setting (midazolam, propofol, s-ketamin, thiopental, fentanyl, remifentanil, and sufentanil)...

Hepatic encephalopathy (HE) is a neurological condition linked to liver failure. Acute HE (Type A) occurs with acute liver failure, while chronic HE (Type C) is tied to cirrhosis and portal hypertension. HE treatments lag due to gaps in understanding its development by gender and age. We studied how sex and age impact HE and its severity with combined liver toxins. Our findings indicate that drug-induced (thioacetamide, TAA) brain edema was more severe in aged males than in young males or young/aged female rats...

AIM: This study aimed to compare the effects of the molecular targeted drugs, sorafenib and lenvatinib, on the survival, invasion, and angiogenesis of hepatocellular carcinoma cells. Additionally, we investigated the involvement of transforming growth factor beta (TGF-β) signaling in their molecular mechanisms. METHODS: To investigate the effects of sorafenib and lenvatinib, we conducted cell viability, invasion, and angiogenesis assays, as well as western blotting analyses...

Wilson's disease (WD) is an inherited disorder of copper metabolism in which pathological copper accumulation, mainly in the liver and the brain, leads to hepatic and/or neuropsychiatric signs and symptoms. Chelators and zinc salts can successfully induce negative copper balance in many patients; however, neurological deterioration may still be observed. This phenomenon can be divided into: (1) early 'paradoxical' neurological deterioration, which usually develops in the first 6 months of anti-copper treatment and may be commonly related to drug type, or (2) late neurological deterioration, which mostly occurs after 6 months of treatment and is often related either to non-compliance with treatment, overtreatment resulting in copper deficiency, or adverse drug reactions...
