Effect of Continuous Glucose Monitoring on Hypoglycemia in Adults With Pancreatogenic Diabetes

This study will investigate the effect of continuous glucose monitoring (CGM) (compared to self-monitoring) on hypoglycemia and glycemic control in patients with insulin-treated pancreatogenic diabetes.

The use of CGM in people with type 1 or type 2 diabetes receiving multiple daily insulin injections improves glycemic control and reduces time spent in hypoglycemia compared to self-monitoring. These beneficial effects of CGM are likely also present in people with pancreatogenic diabetes but have only been sparsely investigated. In this study, the investigators, therefore, aim to investigate the effects of CGM (compared to self-monitoring) on hypoglycemia and glycemic control in patients with pancreatogenic diabetes. Patients with chronic pancreatitis and insulin-treated diabetes will be randomized 1:1 to receive 50 days of CGM followed by 50 days of self-monitoring or vice versa. Each study period is preceded by 20 days of masked CGM assessment, which also serves as the washout period between the two study periods. Furthermore, the self-monitoring group will use masked CGM for the last 20 days of the study period to monitor glucose levels for comparison with the unmasked CGM period. Thus, each study period lasts a total of 70 days. The investigators hypothesize that the use of CGM vs self-monitoring of blood glucose in patients with pancreatogenic diabetes will lead to decreased time spent with a glucose value \<3.0 mmol/l and increased time in glycemic range.
