Background And Aim:
Acute pancreatitis (AP) is a complex disease most commonly caused by gallstones, alcohol intake, or hypertriglyceridemia. Even in subjects with hypertriglyceridemia, the risk of AP is heterogeneous. Identifying individuals with a high genetic susceptibility to AP could contribute to a better risk stratification in the clinic. This study aimed to determine if a weighted polygenic risk score (PRS) of common variants in pancreatitis susceptibility genes can independently predict all-cause AP incidence in the general population.
Methods:
A weighted PRS was calculated for 484 932 individuals from the UK Biobank, including 3346 individuals who developed AP during follow-up. The PRS included eight single nucleotide polymorphisms in known pancreatitis susceptibility genes.
Results:
Individuals with a pancreatitis PRS above the 90th percentile had a 1.21-fold (1.03-1.43; P = 0.02) increased risk of AP compared with those with a pancreatitis PRS below the 90th percentile. When comparing individuals in the third tertile versus the first tertile, the risk of AP was 1.13-fold (1.00-1.28; P = 0.06) higher. Individuals with both a high triglyceride (TG) level and a high pancreatitis PRS (third tertile) had a 2.31-fold (1.83-2.93; P = 3.4 × 10-12) increased risk of AP compared with those with a low pancreatitis PRS and a low TG level (first tertile). Overall, the association between pancreatitis PRS and incident AP was independent of baseline TG level.
Conclusions:
Results of this study suggest that the accumulation of common variants in pancreatitis susceptibility genes is associated with all-cause AP incidence. Pancreatitis PRS could help clinicians identify patients who may be at higher risk of AP and who may benefit from more aggressive treatment.

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.

An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.
