Serological Biomarkers

Exocrine pancreas abnormalities are increasingly recognized as features of type 1 diabetes. We previously reported reduced serum trypsinogen levels and in a separate study, smaller pancreata at and prior to disease onset. We hypothesized that three pancreas enzymes (amylase, lipase and trypsinogen) might serve as serological biomarkers of pancreas volume and risk for type 1 diabetes. Amylase, lipase, and trypsinogen were measured from two independent cohorts, together comprising 800 serum samples from single-autoantibody positive (1AAb+) and multiple-AAb+ (≥2AAb+) subjects, individuals with recent-onset or established type 1 diabetes, their AAb negative (AAb-) first-degree relatives, and AAb- controls. Lipase and trypsinogen were significantly reduced in ≥2AAb+, recent-onset, and established type 1 diabetes subjects versus controls and 1AAb+, while amylase was reduced only in established type 1 diabetes. Logistic regression models demonstrated trypsinogen plus lipase (AUROC=81.4%) performed equivalently to all three enzymes (AUROC=81.4%) in categorizing ≥2AAb+ versus 1AAb+ subjects. For Cohort 2 (n=246), linear regression demonstrated lipase and trypsinogen levels could individually and collectively serve as indicators of BMI-normalized relative pancreas volume (RPV<sub>BMI</sub>, <i>P</i><0.001), previously measured by magnetic resonance imaging. Serum lipase and trypsinogen levels together provide the most sensitive serological biomarker of RPV<sub>BMI</sub> and may improve disease staging in pre-type 1 diabetes.
