Background:
Acute pancreatitis (AP) is a common gastrointestinal disorder, with organ failure being the primary cause of mortality. This study evaluates the combined score of C-reactive protein level and neutrophil-to-lymphocyte ratio (C-NLR score), as a predictor of organ failure.
Methods:
A retrospective analysis was conducted on AP patients admitted to the Hospital Clínico Universitario de Valladolid between March 2014 and January 2022. The C-NLR score was calculated from admission data: patients with both elevated neutrophil-to-lymphocyte ratio (NLR) and C-reactive protein (CRP) were assigned a score of 2, those with one elevated marker received a score of 1, and a score of 0 was given to those with neither.
Results:
A total of 778 patients were included: 611 with mild AP (MAP), 123 with moderately severe AP (MSAP), and 44 with severe AP (SAP). A C-NLR score of 2 was most frequently observed in patients with MSAP (56.1%) and SAP (56.85%), while a score of 1 was more common in patients with MAP (46.9%). Multivariable logistic regression analysis revealed that a C-NLR score of 2 significantly increased the likelihood of organ failure by threefold (OR 3.176; 95% CI 1.297-7.775).
Conclusion:
The C-NLR score could be a useful supplementary tool for predicting organ failure in AP, complementing traditional scoring systems.

01:27Acute 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:
01:24Chronic 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...
