Background:
Severe hypertriglyceridemia (sHTG) can lead to complications, the most serious being acute pancreatitis (AP). Risk of sHTG-induced AP increases with higher triglyceride (TG) levels, resulting in worse clinical outcomes compared to AP due to other etiologies.
Objective:
Characterize health outcomes of patients with combined sHTG and AP (sHTG-AP) compared to patients with sHTG without AP.
Methods:
Our retrospective cohort study estimated clinical outcomes and mortality of patients with sHTG-AP (triglycerides 500-15,000 mg/dL) compared to propensity score-matched patients with sHTG alone, using a nationally representative de-identified claims database with 2012-2022 enrollees.
Results:
A total of 1232 patients with sHTG-AP and 96,207 patients with sHTG without AP were identified. After 1:1 propensity score matching (PSM), 1197 patients from each group were included. Mean (SD) follow-up was 2.9 (2.1) years for sHTG-AP and 3.0 (2.2) years for sHTG without AP (P = .310). Risks of emergency department (ED) visits (hazard ratio [HR] 1.6; 95% CI, 1.6 1.4-1.7; P < .001), hospitalizations (HR 1.7; 95% CI, 1.5-2.0; P < .001), and death (HR 1.8; 95% CI, 1.4-2.4; P < .001) were statistically significantly higher in patients with sHTG-AP; patients with index triglycerides ≥880 mg/dL were also at greater risk. PSM identified 330 patients without baseline type 2 diabetes (T2DM) in each group; probability of developing T2DM was nearly double in patients with sHTG-AP than sHTG without AP.
Conclusion:
ED visits, hospitalizations, and mortality were more common in patients with sHTG-AP than sHTG without AP, warranting better prevention of initial episodes. Prospective studies are also needed to establish causal links between AP and clinical outcomes.

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...
