Background: Several studies suggest a role for EPA- and DHA-derived pro-resolving mediators like resolvins in reversing metabolic and inflammatory disturbances seen in various chronic diseases. Here, we investigated the effects of resolvin D1 (RvD1) on bile duct ligation (BDL)-induced cholestatic liver injury.
Methods: Mice were treated daily with RvD1 or 0.1% ethanol (control) from the day of BDL until the final observation time points. Blood and liver tissue were collected 2, 5 and 14 days after BDL for different analyses.
Results: RvD1 treatment of mice had no impact on the extent of cholestatic liver injury upon BDL, neither in the acute phase nor in the progressive state of liver fibrosis. Although RvD1 treatment resulted in a significantly reduced activity of hepatic stellate cells as well as reduced deposition of extracellular matrix 2 days after BDL, mice were not protected from inflammation and further fibrosis progression.
Conclusions: These data indicate that RvD1 has a limited therapeutic potential to treat cholestatic liver diseases, as it has no significant impact on regression of hepatic necroinflammation and fibrotic changes in bile duct-ligated mice.

Gallstones are among the most frequent hepatobiliary conditions. Although in most cases, they remain asymptomatic, they can cause complications and, in such cases, invasive treatments like endoscopic retrograde cholangiography (ERC) or cholecystectomy are required. Here, we present the results of genetic testing of a single family with a high incidence of symptomatic gallstones and cholestatic liver phenotypes.

Although loneliness and social isolation are proposed as important risk factors for metabolic diseases, their associations with the risk of non-alcoholic fatty liver disease (NAFLD) have not been elucidated. The aims of this study were to determine whether loneliness and social isolation are independently associated with the risk of NAFLD and to explore potential mediators for the observed associations. In this large prospective cohort analysis with 405,073 participants of the UK Biobank, the status of loneliness and social isolation was assessed through self-administrated questionnaires at study recruitment.

Primary Biliary Cholangitis (PBC) is a chronic cholestatic liver disease characterized by the progressive destruction of intrahepatic bile ducts, leading to fibrosis, and potentially cirrhosis. PBC has been considered a prototypical autoimmune condition, given the presence of specific autoantibodies and the immune response against well-defined mitochondrial autoantigens. Further evidence supports the interaction of immunogenetic and environmental factors in the aetiology of PBC.

Objectives: Indications of mitochondrial dysfunction are commonly seen in liver diseases, but data are scarce in primary sclerosing cholangitis (PSC). Analyzing circulating and liver-resident molecules indirectly reflecting mitochondrial dysfunction, we aimed to comprehensively characterize this deficit in PSC, and whether this was PSC specific or associated with cholestasis.
Materials And Methods: We retrospectively included plasma from 191 non-transplant patients with large-duct PSC and 100 healthy controls and explanted liver tissue extracts from 24 PSC patients and 18 non-cholestatic liver disease controls.

Aim: To compare the respective clinical and pathologic features of antimitochondrial antibodies-negative (AMA-negative) primary biliary cirrhosis (PBC) and cholestatic type drug-induced liver injury (DILI) for clinical differential diagnosis.
Patients And Methods: Clinical data from 23 patients with AMA-negative PBC and 39 patients with cholestatic type DILI, treated at our hospital between January 2013 and January 2024, were collected and retrospectively analyzed.
Results: The cholestatic type DILI group exhibited a higher incidence of malaise and abdominal pain compared with the AMA-negative PBC group.
