TOPLINE:
Excessive intrapancreatic fat deposition (IPFD) leading to fatty change of the pancreas (FP) was prevalent in almost 18% of participants in a large population-based cohort, and both IPFD and FP were associated with an increased risk for diabetes, acute pancreatitis, and pancreatic cancer.
METHODOLOGY:
- This prospective cohort study conducted from July 2014 to January 2023 investigated the prevalence of FP and the link between IPFD and pancreatic diseases in 42,599 participants (median age, 65 years; 46.6% men) from the UK Biobank who underwent abdominal Dixon MRI.
- IPFD levels were measured using MRI and a deep learning-based framework called nnUNet.
- The outcomes assessed in this study were diseases of the exocrine pancreas and endocrine pancreas, including acute pancreatitis, pancreatic cancer, diabetes, and other pancreatic conditions.
TAKEAWAY:
- The prevalence of FP was 17.86%.
- Elevation in IPFD levels by one quintile increased the risk for the development of acute pancreatitis by 51.3% (P = .001), pancreatic cancer by 36.5% (P = .017), diabetes by 22.1% (P < .001), and all pancreatic diseases by 22.7% (P < .001).
- FP increased the risk for acute pancreatitis by 298.2% (P < .001), pancreatic cancer by 97.6% (P = .034), diabetes by 33.7% (P = .001), and all pancreatic diseases by 44.1% (P < .001).
- An increasing trend in the prevalence of FP with advancing age was observed in both men and women.
IN PRACTICE:
“FP is a common pancreatic disorder. Fat in the pancreas is an independent risk factor for diseases of both the exocrine pancreas and endocrine pancreas,” the authors wrote.
SOURCE:
This study, led by Xiaowu Dong, MD, of the Pancreatic Center, Department of Gastroenterology, Yangzhou Key Laboratory of Pancreatic Disease, Affiliated Hospital of Yangzhou University, Yangzhou University, Yangzhou, China, was published online in The American Journal of Gastroenterology.
LIMITATIONS:
The authors acknowledged that most of the enrolled participants were White and older than 45 years. A low response rate to recruitment invitations in the UK Biobank database may have introduced self-selection bias. The median follow-up duration of 4.61 years was short and may be insufficient to fully capture the impact of IPFD. Additionally, the use of the average fat fraction for the entire pancreas may have led to spatial variations being ignored.
DISCLOSURES:
This work was supported by the National Natural Science Foundation of China, Cultivation Foundation of Yangzhou Municipal Key Laboratory, The Medical Research Project of Jiangsu Provincial Health Commission, Yangzhou key research and development plan, and Suzhou Innovation Platform Construction Projects-Municipal Key Laboratory Construction. The authors declared no conflicts of interest.
