Abstract

Insights

MicroRNA (miR)-146a and miR-146b levels are elevated in acute pancreatitis (AP) patients, correlating with disease severity and predicting in-hospital death risk. These microRNAs show potential as biomarkers for AP management.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Clinical Diagnostics

Background:

  • Acute pancreatitis (AP) is a serious inflammatory condition with variable severity.
  • Biomarkers are needed for accurate diagnosis, severity assessment, and prognosis prediction in AP.
  • MicroRNAs (miRNAs) are emerging as key regulators in inflammatory diseases and potential diagnostic/prognostic markers.

Purpose of the Study:

  • To investigate the association between microRNA-146a (miR-146a) and microRNA-146b (miR-146b) expressions and the risk, severity, and in-hospital death of acute pancreatitis (AP).
  • To evaluate the potential of circulating miR-146a and miR-146b as biomarkers for AP management and prognosis.

Main Methods:

  • Plasma samples were collected from 50 severe AP (SAP), 50 moderate-severe AP (MSAP), 50 mild AP (MAP) patients, and 50 healthy controls (HCs).
  • miR-146a and miR-146b expressions were quantified using reverse transcription-quantitative polymerase chain reaction (RT-qPCR).
  • Clinical parameters including Ranson's score, APACHE II score, SOFA score, C-reactive protein (CRP), and in-hospital mortality were assessed.

Main Results:

  • Both miR-146a and miR-146b expressions were significantly higher in AP patients (SAP > MSAP > MAP > HCs) and could distinguish between different severity groups and controls.
  • miR-146a expression positively correlated with Ranson's score, APACHE II score, SOFA score, and CRP in all AP groups.
  • miR-146b expression showed positive correlations with severity scores and CRP, with varying degrees across AP severity.
  • miR-146a predicted increased in-hospital death risk in SAP and MSAP patients, while miR-146b predicted it in SAP patients.

Conclusions:

  • Circulating miR-146a and miR-146b levels are significantly associated with the severity of acute pancreatitis.
  • These microRNAs demonstrate potential as valuable biomarkers for predicting in-hospital mortality in AP patients.
  • miR-146a and miR-146b may serve as useful tools for AP management and prognosis assessment.

Acute Pancreatitis II: Clinical Manifestations and Management

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...

Acute Pancreatitis I: Introduction

Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

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...
