| pubmed-article:17318866 | pubmed:abstractText | Acute liver failure (ALF) is characterized by rapid progressive organ failure and poor outcome. The pathophysiology of multiorgan dysfunction in ALF remains unclear but increased systemic inflammatory response is believed to be an important determining factor. Asymmetric dimethylarginine (ADMA), an endogenous nitric oxide synthase inhibitor, results from proteolysis and the liver is a major site for its metabolism. ADMA has been shown to independently predict outcome in multiorgan failure associated with severe liver dysfunction. In this study, we tested the hypothesis that proinflammatory cytokine driven responses are important in modulating ADMA levels in patients with acetaminophen-induced ALF. Blood samples were collected from 10 ALF patients (grade IV encephalopathy) from admission until the time of transplantation or death, and assayed for cytokines and ADMA. A total of 8 patients required treatment for raised intracranial pressure and all patients were managed with standard of care, including full mechanical ventilation and veno-venous hemofiltration. ADMA levels were markedly higher in ALF patients compared to age-matched controls (P < 0.001) and correlated with the levels of proinflammatory cytokines. In pretransplantation patients undergoing hepatic venous catheterization, we demonstrated no significant uptake of ADMA across the failing liver. However, following liver transplantation, ADMA levels reduced acutely. A timed study of ADMA levels during transplantation demonstrated a slight increase during the anhepatic phase but a marked and sustained reduction in ADMA following liver reperfusion. In conclusion, our data show a significant correlation between ADMA levels and proinflammatory cytokines, supporting a hypothesis that proinflammatory cytokines may regulate ADMA metabolism in ALF. | lld:pubmed |
