Objectives:
Cell-free DNA has been investigated as a diagnostic marker in many diseases, including acute conditions. Our hypothesis was that in acute pancreatitis free serum DNA correlates with the extent of pancreatic necrosis and that it may be an early marker of severity.
Design And Methods:
Free DNA was measured in sera from 30 patients with acute pancreatitis at admission, on the first, fourth and seventh day following admission.
Results:
On the first day following admission patients who would develop severe pancreatitis had significantly higher serum DNA levels than those with mild disease (median 0.271 ng/microL vs. 0.059 ng/microL respectively; P<0.001). This parameter showed very good characteristics as a potential severity predictor (area under ROC curve 0.97). Free serum DNA was in correlation with the extent of pancreatic necrosis.
Conclusions:
Free serum DNA correlates with the extent of pancreatic necrosis and is a potential early marker of severe acute pancreatitis.

Acute Pancreatitis I: Introduction
Acute Pancreatitis I: Introduction
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: Introduction
Chronic Pancreatitis I: Introduction
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...
