Objectives:
Complement activation may play a prominent role in acute pancreatitis (AP). Mannan-binding lectin (MBL) and MBL-associated serine protease 2 (MASP-2) participate in complement activation. The objective of the present study was to evaluate the role of MBL and MASP-2 as markers in AP with regard to etiology, inflammatory activity, severity, and development of multiorgan failure.
Methods:
Sixty patients with AP were included. All patients were diagnosed and treated according to a standardized regimen. Blood samples were obtained immediately on admission and again on days 1, 2, and 14.
Results:
Both MBL (P < 0.001) and MASP-2 (P = 0.002) levels changed significantly over time, but without any significant relation to severity, multiorgan failure, or mortality. We found significantly higher levels of MBL (P = 0.04) in alcohol- than in gallstone-induced AP, but no significant difference in MASP-2 levels.
Conclusions:
The MBL and MASP-2 acted as acute-phase reactants, but overall, they were not markers for severity, multiorgan failure, nor for mortality in AP. Our results suggest that MBL and MASP-2 play only a minor role in the inflammatory response in AP.

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.

Chronic Pancreatitis II: Pathophysiology
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...
