Fatty Pancreas Is Independently Associated With Subsequent Diabetes Mellitus Development: A 10-Year Prospective...

Area of Science:

• Metabolic disease research
• Gastroenterology
• Cardiovascular health

Background:

• The link between fatty pancreas and metabolic syndrome is suggested but lacks robust prospective data.
• Long-term prospective studies are needed to clarify the impact of fatty pancreas on metabolic outcomes.

Purpose of the Study:

• To prospectively investigate the association between fatty pancreas and the development of major metabolic outcomes.
• To determine if fatty pancreas independently predicts the incidence of diabetes mellitus, hypertension, and dyslipidemia.

Main Methods:

• Prospective cohort study of 631 subjects (2008-2010) with a mean follow-up of 11.1 years.
• Pancreatic and liver fat quantified using fat-water magnetic resonance imaging.
• Exclusion of subjects with significant alcohol intake or baseline diabetes mellitus; evaluation of incident DM, hypertension, dyslipidemia, cardiovascular events, pancreatic cancer, and mortality.

Main Results:

• 14.7% of subjects had fatty pancreas; this group showed higher incidence of DM, hypertension, and dyslipidemia.
• Fatty pancreas independently predicted diabetes mellitus (aHR, 1.81; P = .020).
• Each 1% increase in pancreatic fat raised DM risk by 7% (aHR, 1.07; P = .016).

Conclusions:

• Fatty pancreas is an independent predictor of subsequent diabetes mellitus development.
• No independent association was found between fatty pancreas and hypertension or dyslipidemia in this cohort.
• Combined fatty liver and pancreas showed the highest DM incidence, suggesting synergistic effects.
