[The relationship between blood sugar control and vascular complications in elderly diabetic patients--investigative study in 17 hospitals of Kochi Prefecture. Kochi Working Group on Diabetes Mellitus].
The aim of this study was to clarify whether the control state of fasting blood sugar can influence the occurrence of diabetic microangiopathy and macroangiopathy even in elderly patients with diabetes mellitus. In Kochi Prefecture 18 internal physicians participated in evaluating clinical courses of 898 patients, consisting of 466 males and 432 females, for an average of 69 months. Elderly cases aged 65 years or more old (group 1) consisted of patients who were aged 71.8 +/- 5.2 years old (M +/- SD). The average age of 481 adult cases under 65 years of age (group II) was 54.4 +/- 8.4 years old. Between the good and poor control groups, there was no difference in terms of blood pressure, body mass index (BMI) and serum lipids. Arteriosclerotic diseases such as myocardial infarction, cerebral infarction and arteriosclerosis obliterans appeared about as frequently in both the good and the poor control groups, while microangiopathies such as retinopathy, nephropathy and neuropathy were significantly more frequent in the poor control group compared to the good control group. The same tendency concerning these complications was seen in group II. Concerning treatment, diet treatment without drug treatment was significantly more frequent in the good control group compared to the poor control group, while hypoglycemic agents and subcutaneous insulin injection were used more often in the poor control group, the more severe state of diabetes mellitus in the latter group. Concerning the main reasons for good control, successful diet treatment was cited most often, followed by regular intake of medications. On the other hand disturbed diet treatment was the most frequent reason for poor control, indicating the strategic importance of diet treatment. Arteriosclerotic diseases were found more often in group I than group II, while the frequency of microangiopathies was similar. Concerning sexes, male patients tended to suffer more often from arteriosclerotic diseases than female patients, but the frequency of microangiopathy was similar. From the above findings it was concluded that poor control of fasting blood sugar level was related to microangiopathies in both non-elderly adult and elderly patients.
