Aim: Chronic liver injury and cirrhosis leads to liver failure. Hyperammonemia is a deleterious consequence of liver failure. On the other hand, oxidative stress seems to play a pivotal role in the pathogenesis of liver fibrosis as well as in the cytotoxic mechanism of ammonia. There is no promising therapeutic agent against ammonia-induced complications. The present study was conducted to evaluate the role of carnosine (CA) administration on liver pathological changes, elevated plasma ammonia, and its consequent events in cirrhotic rats.
Methods: Bile duct ligated (BDL) rats were used as a model of cirrhosis. CA (250, 500, and 1000mg/kg, daily, i.p) was administered for 28 consecutive days to BDL animals. At the end of treatments, markers of oxidative stress and liver fibrosis was determined in liver and serum biomarkers of liver injury and plasma ammonia was assessed. Moreover, changes in animals' locomotor activity were monitored.
Results: Severe bridging fibrosis, inflammation, and necrosis in liver, along with elevated serum biomarkers of liver injury were evident in BDL animals. Furthermore, plasma ammonia was drastically elevated in cirrhotic rats and animals' locomotor activity was suppressed. It was found that CA (250, 500, and 1000mg/kg, daily, i.p) significantly alleviated liver injury and its consequent events in cirrhotic rats. The data suggested that CA is not only a useful and safe agent to preserve liver function, but also prevented hyperammonemia and brain damage as a deleterious consequence of cirrhosis and liver failure.

Skeletal muscle atrophy (sarcopenia) is a serious complication of liver cirrhosis, and chronic muscle inflammation plays a pivotal role in its pathologenesis. However, the detailed mechanism through which injured liver tissues mediate skeletal muscle inflammatory injury remains elusive. Here, it is reported that injured hepatocytes might secrete mtDNA-enriched extracellular vesicles (EVs) to trigger skeletal muscle inflammation by activating the cGAS-STING pathway.

Background: Access to liver transplantation (LT) is affected by geographic disparities. Higher waitlist mortality is observed in patients residing farther from LT centres, but the impact of distance on post-LT outcomes is unclear.
Aims: To evaluate whether the distance LT recipients reside from their LT centre affects graft and patient outcomes.

Background And Aims: Short courses of intravenous (iv) methylprednisolone (MP) can cause drug induced liver injury (DILI). The aim of this study was to assess the clinical features and HLA associations of MP-related DILI enrolled in the US DILI Network (DILIN).
Methods: DILIN cases with MP as a suspected drug were reviewed.

Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), is currently used in the therapy of several solid malignancies. This agent has been associated with several dermatological side-effects, the most common being papulo-pustular acneiform rash. Herein we describe a unique skin effect in a patient treated with erlotinib for non-small cell lung cancer.

Background: Immune checkpoint inhibitors (ICIs) have emerged as the first-line treatment for driver-negative advanced non-small cell lung cancer (NSCLC). However, there is uncertainty regarding the availability and timing of ICI initiation in patients with NSCLC combined with pulmonary tuberculosis (TB). Additionally, the implementation of dual therapy for anti-TB and anti-tumor treatment poses significant challenges in terms of avoiding drug-drug interactions and reducing adverse reactions during clinical diagnosis and treatment.
