The Impact of Inflammatory Markers on Prognosis in Advanced Chronic Liver Disease: Insights From a Prospective Cohort
Background:
Limited research has explored the prognostic significance of the neutrophil-percentage-to-albumin ratio (NPAR), derived neutrophil-to-lymphocyte ratio (dNLR), and systemic immune-inflammation index (SII) in individuals with advanced chronic liver disease (ACLD). This study aimed to examine the association between these inflammatory markers and 90-day transplant-free mortality among patients with ACLD.
Methods:
We prospectively recruited hospitalized patients with ACLD from the tertiary teaching hospital. Cox regressions were used to determine the associations between NPAR, dNLR, SII, and mortality.
Results:
A total of 412 patients with ACLD were included in this study. The 90-day transplant-free mortality increased with higher levels of NPAR, dNLR, and SII. In multivariate analysis, higher NPAR, dNLR, and SII were independently associated with an increased risk of mortality in patients with ACLD after adjustment for confounders. After the adjustment for covariables, the risk of 90-day transplant-free mortality in ACLD patients increased by 66% and 18% for every unit increase in NPAR (OR: 1.66, 95% CI 1.09-2.53) and dNLR (OR: 1.18, 95% CI 1.01-1.38), respectively (p < 0.05). The patients with NPAR < 3.5 (OR: 3.65, 95% CI 1.30-10.27) and dNLR < 3.5 (OR: 2.40, 95% CI 1.19-4.86) had the highest risk. Subgroup analysis revealed that NPAR, dNLR, and SII demonstrated a strong correlation with 90-day transplant-free mortality in both acute decompensation and acute-on-chronic liver failure populations. Subsequent analysis showed a significant association between NPAR, dNLR, SII, and 90-day transplant-free mortality in patients presenting with ascites, infection, and gastrointestinal hemorrhage.
Conclusions:
Increased NPAR, dNLR, and SII were independently correlated with a higher risk of mortality in patients with ACLD.

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
