Background:
Hypertriglyceridemia (HTG) is a major cause of acute pancreatitis (AP). We aimed to determine whether HTG is an independent risk factor for AP complications and construct a prediction model for non-mild AP.
Methods:
We conducted a multi-center cohort study including 872 patients with AP and divided them into HTG-AP and non-HTG-AP groups. Multivariate logistic regression was performed, and a prediction model for non-mild HTG-AP was developed.
Results:
HTG-AP patients had a higher risk of systemic complications, including systemic inflammatory response syndrome [odds ratio (OR): 1.718; 95% confidence interval (CI): 1.286-2.295], shock (OR: 2.103; 95%CI: 1.236-3.578), acute respiratory distress syndrome (OR: 2.231; 95%CI: 1.555-3.200), acute renal failure (OR: 1.593; 95%CI: 1.036-2.450), and local complications such as acute peripancreatic fluid collection (OR: 2.072; 95%CI: 1.550-2.771), acute necrotic collection (OR: 1.996; 95%CI: 1.394-2.856), and walled-off necrosis (OR: 2.157; 95%CI: 1.202-3.870). The area under curve of our prediction model was 0.898 (95%CI: 0.857-0.940) and 0.875 (95%CI: 0.804-0.946) in the derivation and validation datasets respectively.
Conclusion:
HTG is an independent risk factor for AP complications. We constructed a simple and accurate prediction model for progression of non-mild AP.

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...

Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
