Acute Pancreatitis II: Clinical Manifestations and Management

122
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Area of Science:

  • Gastroenterology and Immunology
  • Genomics and Bioinformatics

Background:

  • Acute pancreatitis (AP) is a severe inflammatory condition with high mortality.
  • Identifying reliable biomarkers for AP diagnosis and treatment is crucial.

Purpose of the Study:

  • To identify key genes and mechanisms underlying AP.
  • To explore Prdx4 as a potential diagnostic and therapeutic target for AP.

Main Methods:

  • Differential gene expression analysis on GEO datasets.
  • Machine learning (LASSO, SVM-RFE) for biomarker screening.
  • ssGSEA for immune cell infiltration analysis and immunohistochemistry in AP mouse models.

Main Results:

  • Prdx4 was identified as a potential AP biomarker.
  • Prdx4 expression correlates with immune cell infiltration, particularly in NKT cells, macrophages, granulocytes, and B cells.
  • Recombinant Prdx4 treatment ameliorated pancreatic tissue damage in AP mouse models.

Conclusions:

  • Prdx4 is a potential hub gene for acute pancreatitis.
  • Prdx4 represents a novel therapeutic target for AP management.
