The recent availability of a continuous glucose monitor in pediatric patients offers the opportunity to improve the monitoring in diabetes care.

Material and methods: 62 adolescent patients (13–18 years old) with poor controlled type 1 diabetes (av. HbA1c –10.74%, fructosamine –471 mmol/1) were monitored using the Minimed continuous glucose monitoring system

(CGMS).

Results: A wide range in daily glucose level measurements was observed.

There was a considerable increase of glycemia (>250mg%) at the forenoon hours; most episodes occurred between 9 and 10 AM.

The more frequent incidences of hypoglycemia (<40mg%) were registered at night between 22 PM and 4 AM, in 33% of patients were at 3–4 AM.

Conclusions: 1. The largest insulin requirement in adolescent with poor controlled diabetes mellitus considered forenoon hours. 2. The greater tendency to hypoglycemia episodes at the late hours at the night required nocturnal glycemic profiles to determine. 3. The CGMS is useful tool in monitoring of diabetes care.
