413 NIDDM Sudanese patients were studied. The patients' ages at the onset of diabetes ranged from 20-72 years, with the majority of patients (44%) developing diabetes at the age between 40-50 years. Female to male ratio was 1.9:1. 46.2% of patients were obese and a family history of first degree relatives was obtained in 63% of patients. Complications of diabetes in this study were as follows: Neuropathy (31.5%), retinopathy (17.4%), cataract (16%), nephropathy (9.2%), coronary heart disease (5.1%), cerebrovascular disease (4.4%) and peripheral vascular disease (3.4%). Microangiopathic complications of diabetes were significantly related to the duration of diabetes and the degree of hyperglycaemia (P less than 0.001 using chi 2 test). Macroangiopathic complications were significantly related to aging and hyperglycaemia. Patients with good metabolic control (blood glucose less than 160 mg%) had less prevalence of complications than uncontrolled patients. We conclude that NIDDM is a common type of diabetes in our diabetic clinic. It is a disease with severe complications and morbidity and needs more attention regarding metabolic control, since good control reduces the prevalence of diabetic complications.

Diabetes mellitus and hypertension constitute two powerful independent risk factors for cardiovascular, renal and atherosclerotic disease. The frequent occurrence of the two diseases in the same individual doubles the risk of cardiovascular death, as well as substantially increasing the frequency of transient ischemic attacks, strokes, peripheral vascular disease with lower extremity amputations, as well as end-stage renal disease and blindness. Although hypertension usually occurs in IDDM in association with renal disease, in NIDDM the evolution of hypertension appears to be multifactorial and independent of renal disease. Obesity appears to be dissociable from hypertension and NIDDM with a common link between obesity, hypertension and NIDDM appearing to be hyperinsulinism and insulin resistance. It has been suggested that hyperinsulinism and insulin resistance may lead to hypertension through altered intracellular calcium metabolism, enhanced renal sodium reabsorption, or through an effect of insulin upon lipid and/or catecholamine metabolism. Further, insulin itself may have a direct effect upon the atherosclerotic process in the hypertensive diabetic patient. These considerations have been taken into account in the structuring of antihypertensive therapy in Type I and Type II Diabetes Mellitus.

The responsiveness of renin-angiotensin and kallikrein-kinin systems to furosemide challenge has been investigated in forty-six diabetic patients (34 NIDDM/12 IDDM), subdivided into Group I (uncomplicated DM), Group II (DM with hypertension), Group III (DM with nephropathy), Group IV (DM with hypertension and nephropathy) and a control group of 10 healthy volunteers. Plasma renin activity (PRA) was estimated by radioimmunoassay in blood samples drawn before and 10 min after furosemide administration (0.5 mg/kg i.v.). Urinary kallikrein levels were measured by bioassay using estrogenized rat uterus preparation in 4h urine samples collected before and after the diuretic. Urinary Na+ and K+ were also measured. The basal PRA in diabetics was not significantly different from controls, whereas, urinary kallikrein levels were markedly low in all patients. Both PRA and kallikrein levels increased after furosemide in controls while in diabetics this response was severely blunted. In a subset of Group I, a paradoxical fall in PRA and kallikrein levels was noted after furosemide, an effect similar to that observed in patients with nephropathy (Group III). This response in absence of clinical and biochemical parameters of nephropathy indicates early derangement of renal hemodynamic mechanisms heralding the onset of nephropathy.

We have studied the long term effects of captopril therapy on proteinuria in ten patients with non-insulin-dependent diabetes mellitus with hypertension and nephropathy. There were 7 males and 3 females, with a mean age of 53.3 +/- 10.6 years. After a run-in period of two weeks, therapy with captopril was started. The following parameters were studied: serum glucose, sodium, potassium, cholesterol and triglycerides, glycosylated haemoglobin, renal function and 24 hour urine protein excretion before and at six month intervals for up to 24 months. Average BP fell significantly from 182.5 +/- 28/95 +/- 7.1 to 146 +/- 16.7/76 +/- 18.1 mmHg although no significant changes were seen in the biochemical parameters studied, except a reduction in 24 hour urine protein excretion from 3.86 +/- 2.85 to 0.88 +/- 1.08 g/24 h after 24 months of treatment (P less than 0.01). No correlation was observed between the reduction in proteinuria and any other parameters studied. Our results confirm the reduction of proteinuria in patients with type II diabetes mellitus and stable diabetic nephropathy treated with captopril. This effect was maintained for a period of 24 months.

The prevalence of microalbuminuria and persistent proteinuria was studied in a population of 801 diabetic patients (535 with type II and 266 with type I diabetes). Urinary albumin excretion rate (AER) was measured on morning samples by laser nephelometry. Normoalbuminuria, as defined, in the absence of contaminated urine, by an albumin: creatinine (A/C) ratio below 2, was found in 551 patients, microalbuminuria (NC greater than or equal to 2 with AER below 200 mg/l) in 190 patients and persistent proteinuria (AER greater than or equal to 200 mg/l) in 60 patients. Microalbuminuria was present in 48 (18 p. 100) IDDM patients and 142 NIDDM patients. In IDDM patients, AER increased with the duration of the disease with no apparent influence of age at the onset. The prevalence of hypertension was 25 p. 100 and 61 p. 100 in IDDM patients with microalbuminuria and macroproteinuria respectively versus 10 p. 100 in patients with normoalbuminuria. This prevalence increased in NIDDM patients from 39.3 p. 100 with normoalbuminuria to 40.8 p. 100 and 76.2 p. 100 with microalbuminuria or macroproteinuria respectively. Proliferative retinopathy in type I and type II patients with normal AER was 7.4 p. 100 and 1.2 p. 100 respectively increasing to 15.2 p. 100 and 8.9 p. 100 with microalbuminuria and 27.8 p. 100 and 23.1 p. 100 with macroproteinuria. The prevalence of coronary disease increased from 4 to 10.4 p. 100 in patients with type I diabetes and microalbuminuria. The prevalence of cardiac failure increased from 1.5 to 2.1 p. 100 in type I diabetics and from 3.2 to 7.8 p. 100 in type II diabetics in the presence of microalbuminuria. Patients with microalbuminuria had increased levels of glycosylated hemoglobin A 1C but statistical difference was only obtained for patients with type II diabetes. Routine analysis of AER in diabetics allows early detection of diabetic nephropathy and emphasizes the need for tight metabolic and blood pressure control. Hypertension can be detrimental to nephropathy but might also initiate renal lesions in NIDDM patients.

Two matched groups of insulin requiring non-insulin dependent diabetic (NIDDM) patients with mild proteinuria (200 to 999 mg/day), one on mono component (MC) insulin therapy and the other on conventional insulins were studied for a 3 year period to evaluate the course of nephropathy in these two groups. Twenty-seven and 35 patients were followed-up in the MC insulin and conventional insulin groups respectively. In the MC insulin treated group, the percentage of patients showing deterioration in proteinuria was lower (11% vs 34%, P less than 0.05) and the percentage showing improvement was higher (48% vs 29%) compared to the conventional insulin treated group. Insulin antibody titres decreased significantly in the MC insulin group and serum C-peptide values decreased in both groups on follow-up.

Glucose intolerance is often associated with pancreatitis. Pancreatitis-induced diabetes represents a different clinical syndrome than type I and type II diabetes mellitus. Patients with pancreatitis-induced diabetes may be extremely sensitive to exogenous insulin, rarely develop ketoacidosis, and rarely exhibit classic diabetic complications, such as retinopathy, nephropathy, or accelerated vasculopathy. Pancreatic polypeptide (PP) deficiency has been implicated in the defect of glucose homeostasis found after pancreatitis. This study evaluated intravenous and oral glucose tolerance and insulin response to glucose loading, in the setting of pancreatitis, with and without short-term PP replacement. Dogs (n = 7) underwent pancreatic duct ligation (PDL) and were studied with and without PP infusion (2 micrograms/kg/hr) before PDL and at 1 week, 6 weeks, and 4 months after PDL by means of intravenous and oral glucose tolerance tests. Basal and bombesin-stimulated PP levels at 4 months after PDL were subnormal, verifying PP deficiency in these animals with pancreatitis. PP levels during PP infusion reproduced normal postcibal levels, averaging 897 +/- 40 pg/ml. Glucose tolerance, expressed as the glucose decay constant for the intravenous glucose tolerance tests and as the integrated glucose response for the oral glucose tolerance tests, deteriorated over time and was not improved by acute PP replacement. The integrated insulin response to glucose was not affected by PP. The acute infusion of PP at a dose that reproduces normal postprandial PP levels fails to improve glucose tolerance or augment insulin release in this model of pancreatitis-induced diabetes.

This report presents an overview of the prevalence, characteristics, morbidity, mortality, and risk factors for noninsulin-dependent diabetes (NIDDM) in Blacks and Whites in the United States. Data are drawn primarily from national surveys, but the report also includes the few clinical studies that have differentiated the two races. NIDDM constitutes 90-95% of all diabetes in the United States and is more prevalent in Black Americans than in Whites. Diabetes prevalence increases with age for both races and reaches 26% among Blacks aged 65-74 years compared with 18% among Whites. Rates of diabetes among persons aged 20-74 years are 30% higher in White women, 70% higher in Black men, and 100% higher in Black women, compared with White men. Approximately half of diabetes is undiagnosed in both races. White and Black diabetics are similar with regard to age, duration of diabetes, and diabetes therapies, although Blacks of both sexes are more obese than their White counterparts. Rates of vision loss, amputations, and renal disease are 1.5-4 times higher in Blacks than in Whites, although prevalence of hypertension is about equal in the two races. Blacks and Whites see the same physician specialists for their diabetes, but Whites have approximately 40% more visits to office-based physicians each year. Diabetes-specific mortality has declined significantly in the past decade and may now be lower in Black than in White diabetics. Risk factors for diabetes, including age, sex, obesity, and family history of diabetes, all operate within both race groups and probably interact with each other. The effect of gender and family history on rates of diabetes is similar in Blacks and Whites. Blacks have higher rates of diabetes at each obesity level, indicating that obesity alone cannot explain the differential in prevalence between the races. Impaired glucose tolerance (IGT), a strong risk factor for development of diabetes, increases with age in all race/sex groups except for Black women older than 54 years in whom rates of IGT, decline, possibly because of conversion of IGT to diabetes.

Eighteen patients with non-insulin dependent diabetes mellitus (NIDDM), hypertension and nephropathy were randomized to receive captopril or enalapril for 6 months. Two patients with serum creatinine of greater than 400 mumol/l had to be excluded from the study because of rapidly deteriorating renal function after starting treatment. Of the remaining patients, 7 received captopril and 9 received enalapril. Blood pressure control was achieved in about 50% of patients with either drug alone. Serum creatinine and creatinine clearance were unchanged in both groups but there was a greater tendency for the former to increase in patients with higher pretreatment values. Proteinuria was reduced at 1 month only in the enalapril group which also showed a significant elevation of serum potassium after treatment. Captopril and enalapril have only a modest antihypertensive action in patients with NIDDM and nephropathy. Their use in patients with renal insufficiency must be balanced against the risk of further aggravating the deterioration of renal function.

The effect of a blood pressure reduction by 10 mg extended release felodipine once daily on urinary albumin excretion (UAE) as well as the possible diabetogenic effect of felodipine was studied. A 2 X 12 week placebo-controlled double-blind crossover study was performed in 12 hypertensive non-insulin-dependent diabetic (NIDDM) patients without nephropathy on concomitant treatment with beta-blocker and/or a diuretic agent. Metabolic control as estimated by fasting plasma glucose, hemoglobin A1c and fasting plasma C-peptide was unaltered after felodipine. Blood pressure was significantly reduced by felodipine: systolic 166 +/- 26 mm Hg (placebo) v 153 +/- 26 mm Hg (felodipine) (P less than .05) and diastolic 95 +/- 7 mm Hg v 90 +/- 8 mm Hg (P less than .05). Heart rate was unchanged. There was no correlation between blood pressure and UAE, but the relative change in UAE expressed as UAE placebo/UAE felodipine was significantly correlated to the fall in systolic blood pressure (r = 0.64, P = .03) and mean blood pressure (r = 0.66, P = .02). Since microalbuminuria predicts proteinuria and reduced survival, early antihypertensive treatment may be beneficial in NIDDM as it is in IDDM. Long-term consequences on kidney function and mortality remains, however, to be elucidated.
