Summary

Serum neopterin and IL-6 levels indicate acute pancreatitis (AP) severity. Higher neopterin in severe AP patients suggests it is a reliable prognostic indicator, especially during the first week.

Area of Science:

  • Immunology
  • Gastroenterology
  • Biomarker Research

Background:

  • Cellular immune system activation is implicated in acute pancreatitis (AP) pathogenesis.
  • Excessive leukocyte stimulation may correlate with severe AP.
  • Investigating serum neopterin as a macrophage activation marker in AP is crucial.

Purpose of the Study:

  • To investigate serum neopterin levels in mild and severe AP.
  • To assess the relationship between neopterin, IL-6, and TNF in AP.
  • To evaluate neopterin as a prognostic indicator for AP severity.

Main Methods:

  • Serum neopterin, IL-6, and TNF levels were measured in 17 severe AP and 24 mild AP patients on days 1 and 7.
  • Severe AP was defined by Atlanta criteria and CT scan findings.

  • Normal controls were included for comparison.

    • Main Results:

    • On Day 1, neopterin and IL-6 were significantly higher in severe AP than mild AP and controls.
    • Neopterin levels increased from Day 1 to Day 7 in severe AP patients only.
    • A neopterin cutoff of 40 mmol/ml showed 92% specificity and sensitivity for differentiating severe from mild AP.

    Conclusions:

    • Cellular immune system activation is confirmed in AP.
    • Elevated neopterin and IL-6 levels correlate with AP severity.
    • Neopterin serves as a reliable prognostic indicator for AP, particularly in severe cases.
