title: [Usefulness of continuous glucose monitoring system in detection of hypoglycaemic episodes in patients with diabetes in course of chronic pancreatitis].
abstract: BACKGROUND
  Recently introduced method of glucose monitoring--Continuous Glucose Monitoring System (CGMS, Medtronic MiniMed) now offers new possibilities of assessing metabolic control of diabetes as it records blood glucose values 288 times per day. CGMS is particularly helpful in pancreatogenic diabetes, which is associated with essentially poor metabolic control and higher number of hypoglycemic events.
  
  
  OBJECTIVE
  The study aimed at assessing number of hypoglycemic episodes, including symptom-free hypoglycemic episodes detected with CGMS and glucose meter (GM). TURESTIGALED GROUP AND METHODS: The study comprised 60 diabetic out-patients, treated with insulin in age mean 53.8 +/- 5.1 years, with chronic pancreatitis lasting mean 10.6 +/- 4.6 years and diabetes mellitus-- 4.9 +/- 2.4 years. Serum glucose concentration values were measured with the use of CGMS. Ten measurements of capillary blood glucose concentration with GM were performed daily during the period of CGMS use. Observation period of hypoglycemic episodes lasted 3 days. Hypoglycemic event was detected when glucose value decreased below 60 mg/dl. The number of hypoglycemic episodes, including symptom-free hypoglycemic episodes detected with CGMS and GM was compared.
  
  
  RESULTS
  Number of hypoglycemic events detected with CGMS was five times higher than in GM measurements (p < 0.001). Episodes of symptom--free hypoglycemia were noted in CGMS six times higher than in GM measurements (p < 0.001). Hypoglycemia was found in twice as many patients when diagnosed upon CGMS results as when found upon GM results (p < 0.01). Episodes of symptom-free hypoglycemia were detected in six times as many patients when diagnosed upon CGMS as when analysed upon GM measurements (p < 0.001).
  
  
  CONCLUSIONS
  CGMS offers more complete data on low blood glucose incidents, including symptom-free hypoglycemia, than intensive blood glucose monitoring with the use of glucose meter.
