Metabolic dysfunction-associated liver disease predicts incident liver fibrosis in people with HIV mono-infection: A cohort study.

INTRODUCTION: Metabolic dysfunction-associated liver disease (MASLD) might progress to cirrhosis. We aimed to evaluate the association of MASLD with the risk of developing clinically significant fibrosis (CSF) in people living with HIV (PLWH). METHODS: PLWH have been followed up since 2015 in the PROSPEC-HIV cohort (NCT02542020) with questionnaires, blood samples, and transient elastography (TE) on the same day. Participants with viral hepatitis, who were c-ART naïve, those with CSF at baseline or unreliable TE examinations and who lost follow-up were excluded. Liver steatosis and fibrosis we…

Methotrexate-associated Lymphoproliferative Disorder Showing Colon and Liver Lesions Difficult to Distinguish from Colon Cancer with Liver Metastases.

An 82-year-old man presented with weight loss was being treated with methotrexate (MTX) for rheumatoid arthritis. Computed tomography revealed sigmoid colonic wall thickening and multiple liver masses. Although we initially considered sigmoid colon cancer with liver metastases, the patient was diagnosed with MTX-associated lymphoproliferative disorder (MTX-LPD) based on histopathological findings and clinical course. All the lesions improved after MTX discontinuation. MTX-LPD rarely affects the gastrointestinal tract, particularly the colon. However, our case suggests that MTX-LPDs should be c…

TSC22D1 promotes liver sinusoidal endothelial cell dysfunction and induces macrophage M1 polarization in non-alcoholic fatty liver disease.

BACKGROUND: The progression of non-alcoholic fatty liver disease (NAFLD) to non-alcoholic steatohepatitis (NASH) and liver fibrosis remains poorly understood, though liver sinusoidal endothelial cells (LSECs) are thought to play a central role in disease pathogenesis. AIM: To investigate the role of TSC22D1 in NAFLD fibrosis through its regulation of LSEC dysfunction and macrophage polarization. METHODS: We analysed single-cell transcriptomic data (GSE129516) from NASH and normal mouse models and identified TSC22D1 as a key regulator in LSECs. In vitro and in vivo experiments were conducted …

Generation of Multicellular 3D Liver Organoids From Induced Pluripotent Stem Cells as a Tool for Modelling Liver Diseases.

The liver is an essential organ that is involved in the metabolism, synthesis, and secretion of serum proteins and detoxification of xenobiotic compounds and alcohol. Studies on liver diseases have largely relied on cancer-derived cell lines that have proven to be inferior due to the lack of drug-metabolising enzymes. Primary human hepatocytes are considered the gold-standard for evaluating drug metabolism. However, several factors such as lack of donors, high cost of cells, and loss of polarity of the cells have limited their widescale adoption and utility. Stem cells have emerged as an alter…

Impact of silymarin-supplemented cookies on liver enzyme and inflammatory markers in non-alcoholic fatty liver disease patients.

Nonalcoholic fatty liver disease (NAFLD) is a growing public health concern characterized by fat accumulation and severe disorders like nonalcoholic steatohepatitis (NASH), which are influenced by obesity, inflammatory processes, and metabolic pathways. This research investigates the potential of silymarin-supplemented cookies in managing NAFLD by evaluating their impact on liver enzyme activity, inflammatory markers, and lipid profiles. A clinical trial in Lahore, Pakistan, involved 64 NAFLD patients. Participants were divided into placebo and three treatment groups, with the latter receiving…

Inhibition of 15-prostaglandin dehydrogenase attenuates acetaminophen-induced liver injury via suppression of apoptosis in liver endothelial cells.

Hepatic microvascular disruption caused by injury to liver sinusoidal endothelial cells (LSECs) is an aggravating factor for drug-induced liver injury (DILI). It is suggested that prostaglandin E2 (PGE2) may be able to attenuate LSEC injury. However, it is also known that 15-keto PGE2, a metabolite of PGE2 produced by 15-prostaglandin dehydrogenase (15-PGDH) that is not a ligand of PGE2 receptors, suppresses inflammatory acute liver injury as a ligand of peroxisome proliferator-activated receptor γ. In this study, we aimed to understand whether 15-PGDH activity is essential for preventing DILI…

A Rapid Quantitative Assessment Method for Liver Damage Effects of Compounds Based on Zebrafish Liver Partition Area Ratio.

Total liver area is a traditional indicator in evaluating compound liver damage with zebrafish models. However, in some experiments, compounds changed zebrafish liver morphology but total liver area showed no significant difference, indicating it is inaccurate for evaluating compound effects on zebrafish liver damage. Therefore, in this study, transgenic zebrafish Tg(l-fabp:EGFP) labeled with liver cells using green fluorescent protein was used to evaluate compound effects on liver by the liver partition area ratio. The coefficient of variation of the total liver area and the liver partition a…

The associations between fibrosis changes and liver-related events in patients with metabolic dysfunction-associated steatotic liver disease.

BACKGROUND: The prognosis of metabolic dysfunction-associated steatotic liver disease (MASLD) is associated with liver fibrosis. We investigated the associations between changes in liver stiffness measurement (LSM) over 3-year period and the development of cirrhosis or hepatocellular carcinoma (HCC) in patients with MASLD. METHODS: This study involved patients with MASLD who underwent transient elastography at baseline and 3 years after baseline from 2012 to 2020. Low (L), indeterminate (I) and high (H) LSM values were classified as <8 kPa, 8-12 kPa and >12 kPa respectively. RESULTS: Among 1…

Severe hepatic steatosis promotes increased liver stiffness in the early stages of metabolic dysfunction-associated steatotic liver disease.

BACKGROUND & AIMS: The predictors of progression from steatosis to more advanced stages of metabolic dysfunction-associated steatotic liver disease (MASLD) remain unclear. We evaluated the association between the quantity of hepatic steatosis and longitudinal changes in liver stiffness measurements (LSMs) using magnetic resonance elastography (MRE) in patients with MASLD. METHODS: We retrospectively analysed patients with MASLD who underwent at least two serial MRE and magnetic resonance imaging-based proton density fat fraction (MRI-PDFF) examinations at least 1 year apart. Fine-Gray competi…

Noninvasive liver fibrosis markers are independently associated with carotid atherosclerosis risk in patients with nonalcoholic fatty liver disease.

OBJECTIVE: Nonalcoholic fatty liver disease (NAFLD) is considered an independent risk factor for cardiovascular disease (CVD). The overall morbidity and mortality of CVD increase with higher fibrosis stage in NAFLD. Carotid atherosclerosis (CAS) is an important predictor of cardiovascular events. However, the relationship between liver fibrosis degree and the risk of CAS in NAFLD patients remains uncertain. We aimed to investigate the relationship between noninvasive liver fibrosis markers and CAS risk in patients with NAFLD. MATERIALS AND METHODS: This study included 3,302 participants with …

Pursuing living donor liver transplantation improves outcomes of patients with autoimmune liver diseases: An intention-to-treat analysis.

Living donor liver transplantation (LDLT) offers the opportunity to decrease waitlist time and mortality for patients with autoimmune liver disease (AILD), autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis. We compared the survival of patients with a potential living donor (pLDLT) on the waitlist versus no potential living donor (pDDLT) on an intention-to-treat basis. Our retrospective cohort study investigated adults with AILD listed for a liver transplant in our program between 2000 and 2021. The pLDLT group comprised recipients with a potential living don…

Liver transplantation improves erectile function in patients with end-stage liver disease: a systematic review and meta-analysis.

BACKGROUND: Liver transplantation (LT) has been recognized as the most effective therapy for end-stage liver disease (ESLD). However, the question of whether LT can improve erectile function in patients with ESLD remains controversial. Therefore, we conducted this meta-analysis to evaluate the association between LT and erectile dysfunction (ED). METHODS: According to the PRISMA guidelines, studies were included after conducting searches in four databases from March 2024 onwards. These databases included PubMed, Cochrane Library, Web of Science, and Embase. The primary outcome of interest was…
