Elevated neopterin levels are associated with acute-on-chronic liver failure and mortality in patients with liver cirrhosis
2020
Abstract Background Macrophage activation plays a central role in hepatic and systemic inflammation and is involved in the pathogenesis of acute-on-chronic liver failure (ACLF). Aims This study aimed to investigate neopterin levels in patients admitted for acute decompensation (AD) of cirrhosis, evaluating its relationship with ACLF and prognosis. Methods This prospective cohort study included 205 adult subjects hospitalized for AD of cirrhosis. Twenty-one healthy subjects and 89 patients with stable cirrhosis were evaluated as controls. Results Circulating neopterin was higher in AD as compared to stable cirrhosis and healthy controls (p Conclusions Higher circulating neopterin was associated with ACLF in patients hospitalized for AD of cirrhosis. Neopterin levels were also independently predictors of high short-term mortality, especially among patients with ACLF, and could represent a useful biomarker of macrophage activation in clinical practice.
