Effect of Manufacturing Procedures on Human Islet Isolation from Donor Pancreata Standardized by the North American Islet Donor Score

This study investigates manufacturing procedures that affect islet isolation outcomes from donor pancreata standardized by the North American Islet Donor Score (NAIDS). Islet isolations performed at the University of Illinois, Chicago, from pancreata with NAIDS ≥65 were investigated. The research co...

Description
Summary:This study investigates manufacturing procedures that affect islet isolation outcomes from donor pancreata standardized by the North American Islet Donor Score (NAIDS). Islet isolations performed at the University of Illinois, Chicago, from pancreata with NAIDS ≥65 were investigated. The research cohort was categorized into two groups based on a postpurification yield either greater than (group A) or less than (group B) 400,000 IEQ. Associations between manufacturing procedures and islet isolation outcomes were analyzed using multivariate logistic or linear regressions. A total of 119 cases were retrieved from 630 islet isolations performed since 2003. Group A is composed of 40 cases with an average postpurified yield of 570,098 IEQ, whereas group B comprised 79 cases with an average yield of 235,987 IEQ. One third of 119 cases were considered successful islet isolations that yielded >400,000 IEQ. The prepurified and postpurified islet product outcome parameters were detailed for future reference. The NAIDS (>80 vs. 65–80) [odds ratio (OR): 2.91, 95% confidence interval (CI): 1.27–6.70], cold ischemic time (≤10 vs. >10 h) (OR: 3.68, 95% CI: 1.61–8.39), and enzyme perfusion method (mechanical vs. manual) (OR: 2.38, 95% CI: 1.01–5.56) were independent determinants for postpurified islet yield ≥400,000 IEQ. The NAIDS (>80, p < 0.001), cold ischemic time (≤10 h, p < 0.05), increased unit of collagenase (p < 0.01), and pancreatic duct cannulation time (
