Long term experience with the use of sulfonylurea and/or biguanide oral hypoglycemic agents in patients under the age of 30 years shows the following results: 1) Oral treatment under 30 years of age is effective only for a limited period of time, in the large majority less than 24 months;--2) The success of oral treatment of diabetics and the period of effectiveness is increased if the subject is overweight at the time of discovery of the diabetes mellitus;--3) The type of antidiabetic treatment, i.e., insulin only, oral only, or oral and insulin, does not influence the susceptibility to the complications likely to appear in this age group, such as retinopathy, coronary disease, neuropathies and urinary and dental infections;--4) Poteinuria, peripheral vascular disease and various abnormalities of plasma lipids involving cholesterol and triglycerides, are significantly more common in patients under oral therapy than in those receiving insulin. These findings suggest the necessity for serious reconsideration of therapy as soon as any of these pathological events appear, especially the proteinuria or the lipid anomalies;--5) The duration of the oral treatment preceding therapeutic insulin does not have influence on the subsequent metabolic disturbance (hypoglycemia, deto-acidosis) and thus on the ultimate control of the diabetic state;--6) The somatic growth of the diabetic child is maintained regardless of the type of treatment as long as it is effective. Growth is interrupted however very early if oral treatment becomes ineffective with regard to control of the diabetes. Monitoring of somatic growth during oral antidiabetic treatment is of obvious importance. An interruption in growth is an indication for insulin therapy even if the diabetic control appears satisfactory;--7) The course and the outcome of pregnancy do not appear to be affected by the use of oral therapy at the time of conception. This holds true also for cases in which oral treatment precedes the use of insulin, the pregnancy having commenced during the course of insulin therapy.

The results of renal transplantation in patients with juvenile-onset diabetes mellitus were compared to those of a well-matched control group of non-diabetic patients. All transplantations were performed between 1977 and 1988. In the diabetic group hypertension (72 versus 41%), coronary artery disease (17 versus 0%), and peripheral vascular disease (19 versus 0%) had been significantly more frequent pretransplantation. Fewer diabetic patients had previously been treated with dialysis therapy (69 versus 97%). Graft function measured by creatinine clearance after 1 year follow-up, and incidence of proteinuria were not significantly different. The overall graft survival was significantly worse in the diabetic group compared to the control group: 42 versus 69% after 60 months and 21 versus 62% after 90 months. This was caused by a significantly worse patient survival in the diabetic group after 105 months: 28 versus 78% in the control group. The graft survival following exclusion of the patients who died with a functioning graft did not differ significantly between the groups after 60 and 90 months: 62 and 31% in the diabetic group and 69 and 62% in the control group. The existence of any vascular disease before transplantation, especially pre-existing peripheral vascular disease, had a significant effect on mortality in diabetic patients (P = 0.0003). After transplantation, diabetic patients had significantly more cerebrovascular accidents (23 versus 3%), peripheral vascular disease (31 versus 3%), and number of infections (1.9 versus 1.2). Retransplantation was carried out in each group to the same extent, with the same success rate.

A cross-sectional study was performed to investigate the distribution, methods of detection, and potential risk factors for peripheral vascular disease in a diabetic population with comparison to an age and sex matched non-diabetic group. The population came from a geographically defined area consisting of 10 general practices (total list size 97,034) and covered rural and urban districts of East Dorset. Peripheral vascular disease was defined as an ankle/brachial Doppler pressure ratio of 0.9 or less. Of the diabetic subjects reviewed, 864 were classified as having Type 2 diabetes and 213 Type 1 diabetes. The prevalence of peripheral vascular disease in Type 1 diabetes was 8.7% (95% CI 4.9-12.5) and in Type 2 diabetes 23.5% (95% CI 20.5-26.5), which after adjusting for age was not significantly different (odds ratio 1.5, 95% CI 0.8-2.7, p = 0.18). There was no difference in the frequency of symptomatic peripheral vascular disease or the site of occlusion between diabetic and non-diabetic subjects with peripheral vascular disease. Age, cerebrovascular disease, coronary artery disease, glucose, body mass index, and cholesterol in Type 2 diabetes and age and proteinuria in Type 1 diabetes were significant predictors of peripheral vascular disease. In the non-diabetic group, age and cigarettes smoked were significant variables. These findings suggest that clinical features of peripheral vascular disease in diabetic and non-diabetic subjects are similar but risk determinants may be different.

The association between medical risk factors and the outcome of foot ulcers was evaluated in 208 consecutive diabetic patients with severe peripheral vascular disease (systolic toe blood pressure < or = 45 mm Hg). All patients were treated and followed by the same foot care team. Eighty patients healed primarily, 83 healed after a minor or major amputation, and 45 died. The systolic toe blood pressure was higher among primary healed (30 +/- 13 mm Hg) compared with amputated (22 +/- 15 mm Hg; p < 0.001) and deceased patients (20 +/- 14 mm Hg; p < 0.001). The patients were comparable regarding age, sex, and diabetes and wound duration. Only 41 (19%) patients had intermitten claudication, whereas 153 (77%) lacked palapble pedal pulses, 36% of whom healed primarily. Rest pain occurred in 72 (33%) patients, 38 (47%) of whom had an amputation and 18 (25%) who healed primarily (p < 0.01). Peripheral edema and proteinuria were more common among patients who healed after amputation compared with those who healed primarily (p < 0.001 and p < 0.01, respectively). Signs of sensory neuropathy were found in 158 (77%) patients. There were no differences concerning cardiovascular disease, smoking habits, or short-term metabolic control between patients who healed primarily or after an amputation. In conclusion, diabetic patients with foot ulcers and severe peripheral vascular disease with low systolic toe blood pressure were not excluded from the possibility of primary healing. The most important risk factors for amputation were a systolic toe pressure of less than 30 mm Hg, peripheral edema, rest pain, and proteinuria.

Diabetic patients have an increased mortality following myocardial infarction (MI) due to left ventricular failure rather than larger infarcts or dysrhythmias. As this may be due to diabetic microangiopathy affecting the myocardium, we have examined the case records of diabetic clinic patients admitted to the Coronary Care Unit (CCU) with proven MI and compared the hospital outcome of those with and without retinopathy or nephropathy, i.e. markers for generalised microangiopathy. Sixty four consecutive records were traced, for the period when diabetic treatment policy was standardised in CCU, 24 patients had retinopathy (7 proteinuria). When compared to non-retinopathy patients they had similar ages 67 +/- 12 yr [+/- SD] v 63 +/- 9yr) but were of longer duration of diabetes p less than 0.05). There were no differences between the groups in size or site of infarct, previous infarct or hypertension history, blood glucose on admission or diabetic treatment before or after admission. Death occurred in 29% of retinopathy patients compared to 3% of non-retinopathy patients (p less than 0.01). Cardiac failure complicated 75% of retinopathy patients and 25% of non-retinopathy patients (p less than 0.001). Dysrhythmia occurred in 50% and 33% of patients respectively (P = NS). Nine patients had clinical peripheral vascular disease and five of these died. This study, of a selected group of diabetic clinic attenders admitted to CCU with acute MI, demonstrates that microangiopathy and peripheral vascular disease are important prognostic factors in determining hospital outcome as these patients are at increased risk of cardiac failure and death.

One hundred and eighty-eight known Type 2 diabetic patients aged over 60 years identified by a geographically based survey of a population of 40,076 were followed for a median of 6 years to determine the incidence of various complications. There were 63 deaths and two patients were lost to follow-up. The presence of complications was determined using a structured questionnaire and clinical examination. Incidence rates of ischaemic heart disease, stroke, and peripheral vascular disease (PVD) were 56 (95% CI 41-75), 22 (13-35), and 146 (117-174) 1000-person-years-1 of follow-up, respectively. Rates of stroke and PVD rose significantly with age. Retinopathy occurred at a rate of 60 (42-83) 1000-person-years-1 and cataract at 29 (17-46) 1000-person-years-1 although visual acuity in survivors did not deteriorate overall, probably reflecting the high mortality associated with cataract. The rate of proteinuria (albumin concentration greater than 300 mg l-1) was 19 (9-34) 1000-person-years-1. Incidence rates were unrelated to sex or duration of diabetes. Diabetes is associated with a continuing incidence of complications into old age. Adequate facilities are required to assess and treat the resulting morbidity in a population with an increasing proportion of elderly people.

Mexican Americans have a threefold greater prevalence of non-insulin-dependent (type II) diabetes mellitus than non-Hispanic whites in the San Antonio Heart Study, a population-based study of diabetes. In addition, Mexican-American diabetic subjects (n = 365) have greater fasting glycemia than non-Hispanic white diabetic subjects (P less than 0.001). Despite these findings, and despite a higher prevalence of microvascular complications among Mexican Americans, there does not appear to be a marked difference in prevalence of macrovascular complications between Mexican-American and non-Hispanic white diabetic subjects. Mexican-American diabetic subjects have only a moderate excess of peripheral vascular disease (as judged by ankle-arm blood pressure ratios) relative to non-Hispanic white diabetic subjects (sex-adjusted Mantel-Haenszel odds ratio 1.84, 95% confidence interval 0.75-4.49). Mexican-American diabetic subjects actually reported fewer myocardial infarctions than non-Hispanic white diabetic subjects (sex-adjusted Mantel-Haenszel odds ratio 0.73, 95% confidence interval 0.31-1.71). Duration was not associated with either peripheral vascular disease or myocardial infarction. Severity of glycemia was only mildly associated with presence of peripheral vascular disease and negatively associated with self-reported myocardial infarction. This latter finding may represent a survival bias in that more severe diabetic subjects have already died and are not ascertained in a prevalence study. The absence of an ethnic difference in the prevalence of macrovascular disease contrasts with our previous reports from the San Antonio Heart Study, in which the prevalence of both retinopathy and proteinuria was observed to be higher in Mexican-American diabetic subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

We have examined the relationship between baseline variables and the incidence of new macrovascular complications amongst the 497 members of the London cohort of the WHO Multinational Study of Vascular Disease in Diabetics over a mean 8.33-year follow-up. In univariate logistic regression analysis the incidence of new ischaemic electrocardiographic abnormality was significantly associated with systolic and diastolic blood pressure, diabetes duration and hypertension in patients with insulin-dependent diabetes, and with smoking in patients with non-insulin-dependent diabetes. New myocardial infarction was associated with systolic blood pressure, plasma cholesterol, proteinuria and smoking in patient with non-insulin-dependent diabetes; there were no significant associations among patients with insulin-dependent diabetes. All new ischaemic heart disease was associated with hypertension in patients with insulin-dependent diabetes, and plasma cholesterol and smoking in patients with non-insulin-dependent diabetes. New cerebrovascular disease was associated with systolic and diastolic blood pressure, ECG abnormality and hypertension. New peripheral vascular disease was associated with smoking. Multivariate analysis showed the following significant associations 1) in patients with insulin-dependent diabetes: ECG abnormality; hypertension, myocardial infarction; smoking, ischaemic heart disease; hypertension, diabetes duration and smoking, 2) in patients with non-insulin-dependent diabetes: ECG abnormality; smoking, myocardial infarction; serum cholesterol, proteinuria and smoking ischaemic heart disease; smoking. For new cerebrovascular disease, proteinuria and ECG abnormality were significant predictors in multivariate analysis. Patients with diabetes share many of the established risk factors for nondiabetic subjects, in addition proteinuria may be of significance in the prediction of macrovascular disease in diabetes.

The levels of creatinine, urea, uric acid, UPE and blood pressure were measured in the groups of Type 2 diabetics with proximal (iliocofemoral) type (PRMA) and distal (tibial) type of macroangiopathy (DIMA) (diagnosed by means of Doppler ultrasound technique) and in a control group without lower limb macroangiopathy. Both UPE and creatinine mean values were significantly increased in the PRMA group in comparison with controls. Uric acid levels were increased in both PRMA and DIMA groups and mean urea values did not differ significantly in all three groups of patients. Systolic blood pressure values were similar in each group as well. However, a significant increase of mean diastolic pressure has been observed in the group with DIMA. In addition, significant correlation was observed between the thigh/arm index (expressing the perfusion through the ilicofemoral segment) and UPE (r = -0.464; p less than 0.001). This relationship persisted also in multivariate analysis where UPE was the only factor which entered the "best fit model". The results of the present study indicate that proteinuria might be a risk factor or a marker for proximal type of peripheral vascular disease in Type 2 diabetic mellitus.

The aim of this study was to assess the prevalence and the possible risk-factors for the development of peripheral vascular disease (PVD) in sulfonylurea-treated diabetic patients with proteinuria. Fifty non-insulin-dependent diabetics (NIDDs) with proteinuria (greater than 500 mg/24 h), with age less than or equal to 75 years and duration of diabetes greater than or equal to 5 years, and forty-eight NIDDs without proteinuria, matched for age, sex, body mass index (BMI), duration of diabetes and glycaemic control, were studied using Doppler ultrasound. Risk factors analysed included smoking, hypertension and metabolic indices (cholesterol, HDL-C, triglycerides). The prevalence of PVD was 44% in the proteinuric disease group compared to 14.6% in those without proteinuria (p less than 0.01). Among the risk factors analysed, hypertension and triglyceride concentration were significantly higher in the proteinuric diabetics (p less than 0.01), while HDL-C levels were found to be significantly lower in this group (p less than 0.05). We conclude that the prevalence of PVD was significantly higher in NIDDs with proteinuria. Furthermore, proteinuric patients had higher blood pressure and low HDL-C.
