Modification Patterns of Urinary Albumin Correlates With Serum Albumin and Outcome in Severe Alcoholic Hepatitis.

Background And Aims: Albumin modifications and deranged functions are well documented in serum of severe alcoholic hepatitis (SAH). We investigated whether urinary albumin (u-Alb) can serve as surrogate marker of circulatory albumin phenotype, functionality, and could predict outcome in SAH patients.

Patients And Methods: Baseline serum and urine samples from 100 SAH, 20 alcoholic cirrhosis, and 20 healthy controls were subjected to u-Alb, ischemia modified albumin (IMA), IMA to albumin ratio (IMAr), advanced oxidation protein products, advanced glycation end-products, albumin-binding capacity determination.

Hyperoxidized albumin modulates neutrophils to induce oxidative stress and inflammation in severe alcoholic hepatitis.

Unlabelled: Albumin is a potent scavenger of reactive oxygen species (ROS). However, modifications in albumin structure may reduce its antioxidant properties and modulate its immune-regulatory functions. We examined alterations in circulating albumin in severe alcoholic hepatitis (SAH) patients and their contribution to neutrophil activation, intracellular stress, and alteration in associated molecular pathways.

Dysregulated iron homeostasis is strongly associated with multiorgan failure and early mortality in acute-on-chronic liver failure.

Unlabelled: Acute-on-chronic liver failure (ACLF) is an ailment with high incidence of multiorgan failure (MOF) and consequent mortality. Dysregulated iron homeostasis and macrophage dysfunction are linked to increased incidence of MOF. We investigated whether a panel of circulating iron-regulating proteins are associated with development of MOF and can predict 15- or 30-day mortality in ACLF patients.
