A retrospective record analysis of 112 juvenile-onset diabetics with nephropathy was conducted in order to determine their clinical course. The mean duration of diabetes at the onset of proteinuria was 17.3+/-6.0 years. Early renal failure appeared two years after the onset of protein-uria, and severe renal failure (mean serum creatinine level, 8.5+/-3.9 mg/100 ml) four years after the onset of proteinuria. The mean duration of life after the onset of severe renal failure was six months. The mortality was 53%, with 59% of the deaths attributable to renal failure and 36% to cardiovascular disease. All patients experienced progressive deterioration of renal function as well as the other complications of diabetes, the rate of progression being accelerated toward the end of the course. Juvenile onset diabetics should be considered for renal transplantation before the serum creatinine level reaches 8.5 mg/100 ml.

Among the causes of death in the patients with diabetes mellitus in Ukraine there prevailed cardiovascular disease (73.1 +/- 0.19%); malignant neoplasms ranked second (12.1 +/- 1.2%); tuberculosis constituted 1.6 +/- 1.2%, and all the rest of the diseases - 13.1 +/- +/- 1.2%, including coma - 0.5%. The frequency of death, particularly from cardiovascular diseases, is influenced by the patients' age, the severity and the duration of metabolic disturbances. The methods of treatment, particularly the saccharolytic sulphanilamide preparations, produce no effect on the death incidence.

Abnormal cardiac muscle function has been reported in experimental diabetes mellitus from this laboratory. To examine left ventricular performance in diabetic patients without clinical evidence of myocardial ischemia or other cardiovascular disease, a noninvasive measurement of the systolic time intervals was carried out. Simultaneous recordings of the electrocardiogram, heart sounds, and carotid pulse were made in 25 diabetic subjects, 20 to 56 years of age, and compared with 37 normal subjects. The diabetic subjects had a shorter left ventricular ejection time, longer pre-ejection period, and a higher ratio of pre-ejection period/left ventricular ejection time (P less than 0.001). The isovolumic time was prolonged (P less than 0.001), while heart rate and arterial pressure were within normal limits. Abnormal function was independent of apparent duration and treatment by diet alone, insulin, or hypoglycemic agents. On the basis of available morphologic data in human and canine diabetes, an alteration of the myocardial interstitium may be the basis for this preclinical abnormality in diabetic patients.

During the two and a half year period from January 1971 through Jyly 1973, 23 patients had cultures positive for candida from intra-abdominal isolates. Most of these patients had intestinal or biliary fistulas or abscesses and were seriously ill. Major contributing factors to the development of candidal infections included the extensive use of multiple antibiotics, multiple operations, advanced age, and debility. Thirty additional patients had cultures positive for candida from skin and subcutaneous isolates. Candida appeared to contribute to the poor healing of wounds in some of these patients, particularly those with peripheral vascular ischemic lesions and decubitus ulcers. Antibiotics and concurrent diseases, such as diabetes, cancer, renal failure, and cardiovascular disease, were common factors relating to the development and growth of candida in these patients. There is often considerable difficulty in determing whether or not candida is only a contaminant or is an infectious agent contributing to the illness of the patient. This must be determined in each individual instance. In spite of the fact that candida appeared to be a significant infectious agent in many of these patients, specific antifungal therapy was used sparsely. It is suggested that appropriate antifungal drugs be used in patients with significant disease and that there should be greater awareness of the factors leading to the development of these extremely serious candidal infections.

The present study, concerning 145 insulin-dependent diabetics showed positive relationships between the severity of retinal disease on the one hand, and body weight, blood pressure, and serum cholesterol level on the other. These relationships remain significant when the duration of the clinical diabetes and the age of the patient are taken into account. Two interpretations are suggested. They are not incompatible. In diabetic subjects, either the increase in blood pressure and serum cholesterol level causes an aggravation of diabetic retinopathy or there exists a common factor at the origin of retinal lesions and of an increase in risk of cardiovascular disease through atherosclerosis.

Vascular and neuropathic complications of diabetes are a significant cause of morbidity and mortality. Symmetric polyneuropathy is the most common diabetic neuropathy. Treatment of the mononeuropathies consists of pain control and physical therapy to maintain muscle tone. Prognosis for recovery is excellent. Renal and retinal microangiopathy produce most of the clinically significant mortality and morbidity in diabetes. Recent advances in chronic hemodialysis and renal transplantation have improved the outlook for diabetics with end-stage nephropathy. The poor prognosis for retention of vision in diabetic malignant retinopathy has led to exploration of various forms of palliative therapy, including pituitary ablation, xenon arc coagulation, and laser treatment. Cardiovascular disease is more prevalent among diabetics than among the general population, according to a recent study, and mortality from this cause is three times higher. Animal studies linking aortic wall metabolism and atherosclerotic changes with hyperglycemia suggest that poor control of diabetes may play a role in the development of vascular lesions.

Free and protein-bound serum sugars and serum lipids were analyzed in 65 adult diabetic patients, 10 age-matched controls, and 24 male medical students for correlation of carbohydrate changes with the extent of retinal, renal, and cardiovascular disease. In diabetic sera, both protein-bound sugars and free mannose, fucose, and hexosamine were significantly elevated; free galactose and inositol were elevated in some diabetic patients, and essentially undetectable in sera from controls. Serum triglycerides and pre-beta-lipoproteins were also elevated in diabetics, but alpha-lipoproteins decreased. Although no specific relationships were observed with the extent of retinal and renal disease, bivariate analyses by Pearson coefficients of correlation showed correlations between levels of serum-free mannose and systolic blood pressure, free hexosamine and duration of diabetes, and serum protein-bound fucose and age. Serum triglycerides and pre-beta-lipoprotein levels correlated with insulin therapy. These are preliminary leads of laboratory studies related to carbohydrate macromolecular changes which might aid in a better understanding of the cardiovascular complications associated with diabetes.

Insulin resistance is seen in several pathophysiological conditions, such as obesity, diabetes mellitus, and essential hypertension. This means that a greater than normal amount of insulin is needed to give a normal biological response. A major biochemical defect in insulin resistance seems to be a defect in the intracellular nonoxidative metabolism of glucose in muscle cells. However, in many individuals, there is also increased hepatic glucose output. The result of insulin resistance in individuals with normal insulin-secreting capacity is hyperinsulinemia, a potential risk factor for cardiovascular disease.

Recent studies have indicated that the waist/hip circumference ratio (WHR), an index of abdominal fat distribution, is a risk factor for cardiovascular disease and diabetes, in parallel with other previously established risk factors. Obesity, without taking fat distribution into account, seems to be associated with WHR in its relationship to the metabolic risk factors for these diseases. The important component of the WHR is probably the mass of visceral fat. This cluster of phenomena constitute what has recently been called the metabolic syndrome or syndrome X. Visceral fat mass is probably increased by a multiple endocrine aberration, where steroid hormones are important. This seems to cause insulin resistance by direct effects on the periphery, which may be amplified by the metabolism of the enlarged visceral adipose tissues.

A short review of the metabolic cardiovascular risk syndrome (MCVS) is given. Traditionally, cardiovascular risk has been associated with three so-called "main" risk factors; hypercholesterolemia, hypertension, and smoking. In addition, the association between diabetes and cardiovascular disease has been known for many years in clinical medicine. Primarily, these risk factors have been regarded separately as independent factors, although epidemiological studies showed intercorrelations between them. However, it is now well accepted that relatively few at-risk individuals have only one risk factor, and in many cases a whole "symphony" of factors play together to create what we might call an individuals' risk profile. As an example, very often essential hypertension has been regarded as a disease in itself, which can be successfully treated just by lowering the blood pressure by drugs. When such a strategy obviously failed, the association of elevated blood pressure with dyslipoproteinemia and impaired glucose tolerance attracted more attention, particularly when it was realized that many antihypertensive drugs affected risk in MCVS in a possible negative way. The most important etiologic factor of MCVS is (besides genetics) an excessive caloric intake compared to what the individual spends in physical activity. In the clinical setting, the most important findings of MCVS are central obesity, dyslipoproteinemia with low high-density lipoprotein (HDL) cholesterol, hypertension, reduced insulin sensitivity in peripheral tissues, and increased thrombogenicity. The reduced insulin sensitivity leads to a compensatory increase in beta-cell insulin production, and thereby hyperinsulinemia.(ABSTRACT TRUNCATED AT 250 WORDS)
