[The status of glycemic control and hypoglycemia in elderly patients visiting the outpatient department specializing in diabetes].

Abstract

AIM:

The Japan Diabetes Society (JDS)/Japan Geriatrics Society (JGS) Joint Committee reported 'Glycemic Targets for Elderly Patients with Diabetes' in 2016. Based on this recommendation, we aimed to clarify 1) the achievement status of glycemic targets in the elderly and 2) the presence of hypoglycemia in real life among elderly individuals with an HbA1c below the lower limit.

SUBJECTS AND METHODS:

[Analysis I] In 326 elderly with diabetes ≥65 years of age visiting the outpatient department specializing in diabetes, the proportions of patients with HbA1c values below the lower limit and the use of drugs potentially associated with severe hypoglycemia (e.g. insulin formulations, sulfonylureas, glinides) were investigated. [Analysis II] Of the patients with HbA1c values below the lower limit, seven were tested for hypoglycemia in real life using a continuous glucose monitoring system (CGM).

RESULTS:

[Analysis I] Among the 326 subjects, 235 (72.1%) were using drugs potentially associated with severe hypoglycemia, and 63 (19.3%) had an HbA1c value below the lower limit. [Analysis II] In the seven patients examined using CGM, hypoglycemia was detected in five, all of whom were unaware.

CONCLUSIONS:

A considerable number of elderly patients were taking drugs associated with hypoglycemic risks and had an HbA1c value below the lower limit, some of whom actually had hypoglycemia as detected by CGM. Using tools such as CGM, preventive measures against hypoglycemia should be taken.
