Type II, non insulin dependent diabetes mellitus is commonly diagnosed after the age of 45 years. For this reason it was previously called maturity onset diabetes. Type II diabetes occurring in young subjects has generally been described in selected pedigrees. The purpose of this work was to review data from all the unrelated type II diabetics (with fasting hyperglycemia) diagnosed before the age of 45 and observed in our department over the last four years. A total of 90 such patients including 44 men and 46 women were included in this study. Of 43 cases diagnosed before the age of 30, there were 30 women compared to only 16 women out of 47 cases diagnosed between 30 and 45 years (p less than 0.001). At the time of diagnosis 42 patients had a relative body weight lower than 120%. In 66,7% of the cases, one parent was a known diabetic. The rate of diabetes in the sibships was 50%. Differences in family history of diabetes were not observed in relation to age or weight at diagnosis. Comparison with a series of 150 conventional type II diabetics in whom diagnosis was made between 45 and 60 years of age showed a significantly greater frequency of obesity (86%) and fewer diabetic parent (36%). The mean apparent duration of diabetes was 14 years (range 5-42). Microangiopathy was not infrequent in these diabetic patients. Twenty-three patients had retinopathy, proliferative in 8 cases, and 3 were blind. Nine had renal insufficiency, severe in 3 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

By a complex biochemical, immunologic, morphohistochemical and ultrastructural study, carried out on a group of 42 obese and 38 diabetic children, comparatively with 12 normal controls, the authors arrive at conclusions which prove that obesity and diabetes mellitus carry great atherogenic risk factors. Even though the intimate atherogenesis mechanism is not perfectly known, the abnormal values of insulinemia, lipidemia and cortisolemia are certainly involved in this process. In diabetes mellitus the immunologic factor is also involved. Microangiopathy in diabetes mellitus and capillary lesions in the adipose tissue of obese children may also represent atherogenic risk factors. An efficient prophylaxis in atherosclerosis must therefore begin in childhood.

Diabetes mellitus has recently markedly increased among elderly patient's diseases. There are no recent epidemiological reports on the relative number of male and female diabetic patients. So, an epidemiological study was performed on 746 Non-Insulin-Dependent Diabetes Mellitus patients, whose data were obtained from members of the Himeji Internal Medicine Association, divided into six groups according to sex and duration of illness. The following results were obtained. 1) The number of male patients was greater by about 20% than that of female patients, while elderly patients accounted for a larger proportion, nd age at onset of disease was about ten years higher in female than in male patients. 2) All indicators of diabetes mellitus became worse with longer duration of illness. 3) There was a correlation between the prevalence of complications and the duration of illness: The prevalence of complications increased in parallel with increasing duration of illness, and this tendency was more marked in female than in male patients. 4) Female patients had a more marked tendency to develop hypertension, hyperlipidemia and obesity than male patients. 5) Microangiopathy generally manifested itself earlier than macroangiopathy, and the increase in the prevalence of angiopathy in accordance with prolonged duration of illness was more marked for microangiopathy than for macroangiopathy. Clinical features of Japanese diabetics are found to be similar to those of Europeans, especially dominant in females. This might be due to the changing life style in japan.

Retinopathy has been increasing in prevalence as a consequence of type 2 diabetes and a cluster of coexisting risk factors characterized as the metabolic syndrome. However, the combined effects of these conditions on the retina are poorly understood. Therefore, we focused on the spontaneously hypertensive corpulent rat (SHR/N-cp), a model with type 2 diabetes, obesity and features of the metabolic syndrome to characterize retinal changes at a structural and functional level. SHR/N-cp males at 4 and 8 months of age were used in this study. Metabolic parameters and blood pressure were measured by standard methods. Morphology was investigated by histological techniques supplemented by nicotinamide adenine dinucleotide phosphate-diaphorase staining of whole mounts and fluorescein angiography to analyze the retinal vasculature. The in vivo function of the retina was examined by electroretinography (ERG). Obese SHR/N-cp rats were hypertensive and showed significant increases in body weight, serum levels of glucose, triglycerides, total cholesterol and urinary glucose excretion compared with lean controls (P < 0.01 for each). Histology indicated an overall intact integrity of the retina and aspects of microangiopathy in obese SHR/N-cp rats. ERG revealed intact processing of light signals but significantly decreased amplitudes of b-waves for all (P < 0.01) and of a-waves for some examined light intensities (P < 0.05). Oscillatory potentials were significantly protracted (P < 0.01), whereas amplitudes were not reduced. Microangiopathy and electroretinographic deficits combine to produce an early non-proliferative retinopathy phenotype in the obese SHR/N-cp rats. Thus, this model represents a valuable experimental tool to obtain further insights into the mechanisms of retinopathy in the context of obesity, type 2 diabetes and metabolic syndrome.
