Impact of attaining an aggressive PK/PD target with continuous infusion beta-lactams on the clinical efficacy of targeted therapy of early post-transplant Gram-negative infections in critically ill OLT recipients. An interim analysis of a 3-year prospective, observational, study.

Background: To assess the impact of attaining aggressive beta-lactam pharmacokinetic/pharmacodynamic (PK/PD) targets on clinical efficacy in critical orthotopic liver transplant (OLT) recipients with documented early Gram-negative infections.

Methods: OLT recipients admitted to the post-transplant ICU between June 2021 and May 2024 having documented Gram-negative infections treated with targeted therapy continuous infusion (CI) beta-lactams, and undergoing therapeutic drug monitoring (TDM)-guided beta-lactam dosing adjustment in the first 72 hours were prospectively enrolled. Free steady-state concentrations (fCss) of beta-lactams (BL) and/or of beta-lactamase inhibitors (BLI) were calculated, and aggressive PK/PD target attainment was measured.

Perioperative administration of albumin in adult patients undergoing liver transplantation: A systematic review.

Hypoalbuminemia is a risk factor for mortality in patients with end-stage liver disease (ESLD) and in those undergoing orthotopic liver transplantation (OLT), since it represents a biomarker of post-operative delayed functional recovery of the graft. Despite albumin infusion during and after OLT is frequently adopted in recipients with hypoalbuminemia, it remains unclear whether this procedure could improve post OLT clinical outcomes. Observational studies indicated that treatment with albumin after OLT might be beneficial in reducing ascites and acute kidney injury (AKI) development.

Impact of SARS-CoV-2 vaccination in patients with vascular liver diseases: Observations from a VALDIG multicenter study.

Our aim was to assess the prevalence of bone fragility fractures and contributing factors in a large modern cohort of liver transplant recipients. Retrospective study of 429 consecutive patients receiving liver transplantation from 1/1/2010 to 31/12/2015.

Beta-Blockers Lower First Decompensation in Patients With Cirrhosis and Enduring Portal Hypertension After Etiological Treatment.

Background And Aims: Non-selective beta-blockers (NSBBs) can lower the risk of first decompensation in patients with cirrhosis and clinically significant portal hypertension (CSPH) (identified by a hepatic venous pressure gradient ≥10 mm Hg) with active etiology. Our aim was to examine the effect of NSBBs on first decompensation occurrence in patients with cirrhosis and enduring CSPH after etiological treatment.

Methods: Patients with compensated cirrhosis and clinical evidence of CSPH (gastroesophageal varices [GEVs] and/or spontaneous portosystemic collaterals [SPSSs]) after 2 years from etiological treatment.

Sex disparities in acute-on-chronic liver failure: From admission to the intensive care unit to liver transplantation.

Acute-on-chronic liver failure (ACLF) is a severe clinical syndrome characterized by acute liver decompensation in patients with chronic liver disease, marked by systemic inflammation and systemic organ failure. In this review, we discussed sex-related disparities in the incidence, prognosis, and access to liver transplantation (LT) for patients with ACLF, particularly during Intensive Care Unit (ICU) management. Some studies have suggested that ACLF is more prevalent among male patients admitted to the ICU, and they have higher mortality rates than females.
