Portal hypertension is a constant companion of numerous diseases in gastroenterology, vascular surgery, cardiology, and hematology with grave consequences for the health and life of patients. The development of portal hypertension leads to significant violations of hemodynamics in the liver vessels and the development of arterial and venous hypertrophy, stasis of blood in the vessels of the portal tract. In the experiment on rats, portal hypertension was simulated in an original way with the following study of the peculiarities of morphological changes in the internal structure of the kidneys and gonads in males as a manifestation of a violation of systemic hemodynamics. The decrease of the renal artery throughput in portal hypertension, dystrophic changes in the epithelium against the background of venous congestion, paravazal polymorphocytic infiltration and proliferation of the connective tissue have been identified.

High interstitial fluid pressure enhances USP1-dependent KIF11 protein stability to promote hepatocellular carcinoma progression.
J Transl Med
January 2025
Department of General Surgery, The Second Affiliated Hospital, Jiangxi Medical College, Nanchang University, No.1, Minde Road, Nanchang, 330006, Jiangxi, China.
Background: HCC is characterized by a high interstitial fluid pressure (HIFP) environment, which appears to support cancer cell survival. However, the mechanisms behind this phenomenon are not fully understood.
Methods: This study investigates the role of kinesin family member 11 (KIF11) in HCC under HIFP conditions, using both in vivo and in vitro models.

Background: Positivity for anti-gp210 and anti-centromeric antibodies (ACA) in patients with primary biliary cholangitis (PBC) have been associated with the progression of liver failure and portal hypertension (PH), respectively. The value of combining risk autoantibody assessments with prognostic scoring systems in improving risk assessment in patients with PBC remains unclear.
Aims: To investigate the prognostic significance of various combinations of anti-gp210 and ACA statuses and their enhancing the prognostic utility on the GLOBE scoring system.
Current Concepts in Fluid Resuscitation and Vasopressor Use in Cirrhosis.
Semin Liver Dis
January 2025
Hepatology, University of Pennsylvania, Philadelphia, United States.
Critically ill patients with cirrhosis and liver failure not uncommonly have hypotension due to multifactorial reasons, that include hyperdynamic state with increased cardiac index, low systemic vascular resistance due to portal hypertension, following the use of beta blocker or diuretic therapy, and severe sepsis. These changes are mediated by microvascular alterations in the liver, systemic inflammation, activation of renin angiotensin aldosterone system, and vasodilatation due to endothelial dysfunction. Hemodynamic assessment includes measuring inferior vena cava indices, cardiac output and systemic vascular resistance using point-of-care ultrasound (POCUS), in addition to arterial waveform analysis, or pulmonary artery pressures, and lactate clearance to guide fluid resuscitation.

Background: Cytomegalovirus (CMV) is a significant cause of morbidity and death in solid organ transplant recipients. Pre-emptive treatment of patients with CMV viraemia using antiviral agents has been suggested as an alternative to routine prophylaxis to prevent CMV disease. This is an update of a Cochrane review first published in 2006 and updated in 2013.

Liver Int
February 2025
Division of Gastroenterology and Hepatology, Department of Medicine III, Medical University of Vienna, Vienna, Austria.
Background And Aims: Porto-sinusoidal vascular disorder (PSVD) is a rare vascular liver disorder characterised by specific histological findings in the absence of cirrhosis, which is poorly understood in terms of pathophysiology. While elevated hepatic copper content serves as diagnostic hallmark in Wilson disease (WD), hepatic copper content has not yet been investigated in PSVD.
Methods: Patients with a verified diagnosis of PSVD at the Medical University of Vienna and available hepatic copper content at the time of diagnosis of PSVD were retrospectively included.
