A random sampling of males and females aged 20 to 69 (1125 males and 1243 females), residing in Moscow, were investigated. The first screening was in 1979, the final one--in 10 years. The program of the first screening included anthropometry, evaluation of the CVS, carbohydrate and fat metabolism, studies on hereditary aggravation with regard to diabetes mellitus (DM); the program of final screening included the state of carbohydrate metabolism. Data processing was done using methods of multidimensional analysis. Independent signs to be used as predictors of noninsulin dependent diabetes mellitus were shown to be the age of 40 and older, a general GTT index of 16, and atherogenicity coefficient values of 3.5 and lower in men, and the presence of dyslipoproteinemia in women.

We analyzed O-GTT obtained from 375 children (group A; 7-11 years old) and adolescents (group B; 12-16 years old), including 96 normal non-obese cases, 266 simple obese cases (172 with normal O-GTT, 79 with border line type O-GTT and 15 with diabetic type O-GTT), 8 obese NIDDM cases and 5 non-obese NIDDM cases. The results were as follows; 1) The levels of epsilon CPR (in terms of total sum of the values measured at 0, 30, 60, 120 and 180 minutes on O-GTT) in the obese children and adolescents were only 1.5 and 1.2 times as high as in the control group. The levels of epsilon CPR/epsilon IRI molar ratio in the control group were 2.0 and 2.3 times as high as in the obese children and adolescents. These data suggest that hyperinsulinemia in the obese children and adolescents is caused mainly by decreased hepatic insulin extraction rather than by increased insulin secretion. 2) In the non-obese NIDDM adolescents, the levels of epsilon CPR decreased to about 3/4 of those in the control group; in contrast, the epsilon CPR/epsilon IRI molar ratio increased. Therefore, it seems that there is increased hepatic insulin extraction as well as decreased insulin secretion in the non-obese NIDDM adolescents. 3) In the obese NIDDM adolescents, the levels of epsilon CPR were nearly the same as in the control group and the epsilon CPR/epsilon IRI molar ratios were slightly lower as the disease state of NIDDM counterbalanced obesity.

A study was made of the interrelationship of myocardial perfusion with physical working capacity in different types of DM (with the duration of disease from 4 to 8 years without clinical signs of circulatory insufficiency). Rated physical exercise testing in 12 patients with insulin dependent diabetes and 27 patients with noninsulin dependent diabetes as well as in 40 healthy subjects has shown a GTT decrease in diabetes mellitus irrespective of patient's age, sex and body mass to be more marked in noninsulin dependent type and to be closely related to disturbed oxygen supply of the heart and a lowered myocardial reserve. Bicycle ergometric testing combined with 201Tl scintigraphy in 20 patients has shown disorder of perfusion in all the patients irrespective of a diabetes type and duration of disease. Insulin dependent diabetes mellitus was characterized by stable perfusion defects resulting from metabolic derangements, and noninsulin dependent diabetes mellitus was characterized by a decrease in the level of a maximum Tl uptake by the myocardium and transient perfusion defects of ischemic type.

During the period from 1974 through 1988, we annually examined approximately 225,000 to 386,400 school children residing in Tokyo for glycosuria to detect juvenile diabetes. If the first test was positive for glucose, glycosuria was confirmed by a second test. In children who gave a positive result in both the first and second tests 0-GTT were performed. All 124 patients were diagnosed as NIDDM according to the criteria of the WHO Report on Diabetes of 1985. The incidence of NIDDM in children in Japan has increased in recent years and from 1984 to 1986 was approximately 3.8 per 100,000 per year. The frequency of NIDDM increases with age up to 14 years. In about 84% of cases, the body weight at diagnosis is more than 20% above the ideal weight and the height is often above average. There is a high frequency in families with a history of diabetes. Diet and exercise therapy in newly diagnosed patients irrespective of the presence or absence of obesity may result in remission, but some cases may require insulin therapy or oral administration of a hypoglycemic drug to obtain a better glycemic control. Children with NIDDM are more likely to be complicated by incipient retinopathy within two years after diagnosis than those with IDDM. Therefore, it is important to keep strict glycemic control to prevent diabetic complications in NIDDM children just as in juvenile onset IDDM.

HLA antigens (A, B, DR) of the tissues of 171 patients with different types of diabetes mellitus were investigated. Controls were 1867 healthy Leningrad residents (control I), not investigated with the GTT, and 38 pregnant women with the unchanged GTT during pregnancy (control II). Some features of the frequency of occurrence of individual antigens and their interlocular (HLA A, B) combinations in type I and type II diabetes mellitus and diabetes of pregnant women were established. The risk of diabetes mellitus, type I, development was shown to be on the increase in the presence of HLA DR4 in the phenotype and considerably on the decrease in the presence of HLA B17. The results point out to the genetic heterogeneity of different types of diabetes mellitus. The authors think it possible to use HLA typing for the diagnosis of type I diabetes mellitus.

Hyperglycemia and other metabolic derangements resulting from absolute or functional deficiency of insulin are accompanied by typical signs and symptoms of diabetes. The clinical signs and the findings of hyperglycemia over 200 mg/dl should establish a diagnosis of diabetes mellitus. An oral glucose tolerance test (O-GTT) is rarely necessary for diagnosis of diabetes in a child. A small proportion of children, however, present less severe symptoms, and may require an O-GTT. Approximately 14% of IDDM children were in coma at diagnosis in Tokyo, and 11 onset deaths (0.94%) were observed among the 1172 newly diagnosed IDDM cases in Japan. A significant decline in the onset mortality, however, has been observed in the past 20 years in Japan in association with the improvement of early management of childhood diabetes. The clinical distinction of IDDM from NIDDM is often difficult in diabetic children of Oriental origin without obesity. Japanese IDDM can be divided into two forms, abrupt and slow onset forms, but they may be essentially the same disease. There was no difference in the frequency of being tested positive for circulating ICA between the two groups of the patients. But a difference in the frequency of HLA DR4 and DRW9 was noticed between the two groups. Clinical features of 107 children with NIDDM were studied and about 75% of these cases were obese. All of them can be detected by routine urinalysis for glucose. Diet and exercise therapy in most of the newly diagnosed patients resulted in remission but some of them may require insulin or an oral hypoglycemic agent to get better glycemic control.

The authors describe the results of i. v. GTT in 10 patients with diabetes mellitus before and after a course of hyperbaric oxygenation, in 5 of them the test was repeated. The results of the test were processed with the help of a new type of model of glucose kinetics based on the production of glucose by the liver and its elimination in the test. A new quantitative criterion (the so-called rho-criterion) of a degree of carbohydrate metabolic derangement was introduced for diabetic patients. Its calculation before and after a course of HBO permitted reliable quantitative assessment of the efficacy of sugar lowering therapy in such patients. The new method permitted the assessment of the production of glucose by the liver and the rate of its elimination in i.v. GTT. The mechanism of HBO-action was unraveled (the suppression of glucose production by the liver). Examples of 2 patients with type II diabetes mellitus have demonstrated the efficacy of the rho-criterion in the prediction of a sugar lowering effect of antidiabetic tablets in serious clinical situations.

The paper is concerned with an analysis of examination of 414 relatives of the 1st-3rd degree of relationship in 230 families of probands with diabetes mellitus of different types. The frequency of detection of insulin dependent diabetes mellitus (IDDM) among relatives of the 1st degree of relationship in the families of IDDM probands was 1.0 +/- 5.8%. Patients with noninsulin dependent diabetes mellitus (NIDDM) were not detected in these families. The frequency of NIDDM detectability among relatives of the 1st-3rd degree of relationship in the families of NIDDM probands was 38.2-2.5%. IIDM was most common in relatives of the 1st degree of relationship, particularly in women aged 50 to 60 suffering from obesity. A follow-up of relatives with disturbed GTT in the families of NIDDM probands revealed NIDDM in 30% and regression up to normal GTT in 50%.

Secrepan (Eisai Co. Tokyo, Japan) was administered to 9 healthy volunteers and 36 patients with non-insulin dependent diabetes mellitus (NIDDM) to clarify the effect of secretin on the pancreatic B-cell, by determining the changes in blood of insulin (IRI). Whereas IRI in healthy subjects showed a monophasic change, reaching a peak (delta IRI = 43 +/- 7.3 microunits/ml, M +/- SE) 5 min after secretin loading and returning to the basal level in 15 min, NIDDM patients on diet therapy (delta IRI = 40.2 +/- 7.6 microunits/ml) showed no significant difference from the control group, but NIDDM patients on sulfonylurea (SU) (15.5 +/- 2.4 microunits/ml) and those on insulin therapy (5.3 +/- 1.4 microunits/ml), both showed a significant depression in responsiveness. Further, the changes in insulin secretion after atropine administration in healthy subjects and the changes in IRI response to Secrepan in vagotomized patients were also determined. As a result, data which preclude the possibility of association of the vagus nerve and cholinergic nerve with the stimulation of insulin secretion by secretin were obtained, and a direct action of secretin on the cell of islets of Langerhans was suggested. The maximum IRI response after a secretin load had a significant positive correlation with the IRI response after a 75-gm GTT and the content of C-peptide immunoreactivity in 24-hour urine. Therefore, insulin response to a secretin load can be useful in assessing endogenous insulin secretion and provides a pertinent clinical guide for the selection of an appropriate therapy for diabetes mellitus.

Changes in the secretion and metabolism of insulin were measured by estimating serum C-peptide and insulin and their ratio during oral GTT in 30 non obese and 12 obese NIDDM patients. The mean IRI and CP responses were low in both groups of patients, compared to weight-matched controls. The reduction in CP was more marked than the reduction in IRI. The molar ratio of insulin and CP was found to be elevated in the patients, probably indicating reduced hepatic and peripheral extraction of insulin. It was noted that the elevated IRI/CP ratio was a 1) a common feature in NIDDM, irrespective of the body weight, 2) it is present even under basal conditions when the insulin levels are the lowest, 3) it appears to be independent of the concentration of insulin reaching the liver, and 4) obese patients appear to have an exaggerated defect compared to their non obese counterparts.
