Glycemic Variability Assessment in Newly Treated Exocrine Pancreatic Insufficiency With Type 1 Diabetes

J Diabetes Sci TechnolPublished N-of-1 case study

Authors' conclusion

GV can aid in assessing response to new-onset medications, as was demonstrated in this article for n = 1 individual with type 1 diabetes (using an open-source AID) after commencing PERT for newly identified EPI. GV may be useful for evaluating the efficacy of new-onset medications for people with insulin-requiring diabetes.

Study context

Population
Individual with T1D using open-source automated insulin delivery (AID), newly identified EPI
Participants
1 participants
Comparison
1 month before vs 1 month after pancreatic enzyme replacement therapy (PERT) commencement
Outcome
Glycemic outcomes and glycemic variability (GV) after meals
Follow-up
1 month before vs 1 month after PERT
Methodological detailsbefore-after comparison, self-tracked data, open-source AID, Diabetes data uploaded via Nightscout to Open Humans; macronutrient, PERT intake and EPI symptoms self-tracked
  • Before-after comparison
  • Self-tracked data
  • Open-source AID
  • Diabetes data uploaded via Nightscout to Open Humans; macronutrient, PERT intake and EPI symptoms self-tracked

Main finding

As reported in the abstract

  • Time in range already above goal and improved further after PERT
  • Glucose rate of change and excursions >180 mg/dL reduced
  • Mean high blood glucose index reduced overall and more so at breakfast after PERT
