Chronic Pancreatitis I: Introduction

890
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
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...

Area of Science:

  • Microbiome research
  • Gastroenterology
  • Computational biology

Background:

  • Pancreatitis alters oral and gut microbial composition, leading to dysbiosis.
  • This dysbiosis may influence disease mechanisms and offer diagnostic or therapeutic targets.

Purpose of the Study:

  • To determine if oral or gut microbial signatures can classify chronic pancreatitis (CP).

Main Methods:

  • Collected 707 stool samples from healthy controls (HC) and pancreatitis patients (CP, AP, RAP).
  • Analyzed microbiome composition using whole genome sequencing.
  • Employed machine learning to identify microbial features predictive of CP.

Main Results:

  • Gut microbial alpha diversity was reduced in all pancreatitis groups compared to HC, with CP showing the lowest.
  • Beta diversity analysis revealed distinct gut microbiome compositions between HC and CP.
  • Machine learning models accurately predicted CP using gut microbial species (AUC: 0.834).

Conclusions:

  • A gut microbial signature was identified that is predictive of CP.
  • Machine learning models successfully identified this signature in a large cohort.
  • The findings highlight the potential of the gut microbiome for CP diagnosis.
