Diabetes mellitus and hypertension are common diseases that coexist at a greater frequency than chance alone would predict. Hypertension in the diabetic individual markedly increases the risk and accelerates the course of cardiac disease, peripheral vascular disease, stroke, retinopathy, and nephropathy. Our understanding of the factors that markedly increase the frequency of hypertension in the diabetic individual remains incomplete. Diabetic nephropathy is an important factor involved in the development of hypertension in diabetics, particularly type I patients. However, the etiology of hypertension in the majority of diabetic patients cannot be explained by underlying renal disease and remains "essential" in nature. The hallmark of hypertension in type I and type II diabetics appears to be increased peripheral vascular resistance. Increased exchangeable sodium may also play a role in the pathogenesis of blood pressure in diabetics. There is increasing evidence that insulin resistance/hyperinsulinemia may play a key role in the pathogenesis of hypertension in both subtle and overt abnormalities of carbohydrate metabolism. Population studies suggest that elevated insulin levels, which often occurs in type II diabetes mellitus, is an independent risk factor for cardiovascular disease. Other cardiovascular risk factors in diabetic individuals include abnormalities of lipid metabolism, platelet function, and clotting factors. The goal of antihypertensive therapy in the patient with coexistent diabetes is to reduce the inordinate cardiovascular risk as well as lowering blood pressure.

Hypertension should be detected and treated early in diabetic patients. It markedly affects the morbidity and mortality of diabetic individuals as a result of both atherosclerosis and microvascular disease. Antihypertensive treatment is an effective tool in slowing the progression of early and advanced diabetic nephropathy. No prospective studies have addressed the effects of antihypertensive regimens on the incidence of congestive heart failure, stroke, and coronary artery disease in large groups of diabetic patients. Such studies are urgently needed. Special consideration should be given to the effects of antihypertensive drugs on glycemic control and the lipid profile of the diabetic patient. Because hyperinsulinemia (and insulin resistance) have been advocated as hypertensive and atherosclerotic risk factors, the effects of antihypertensive drugs on insulin action and plasma insulin levels may become an important element in the selection an antihypertensive agent. More information, however, is needed in these areas. ACE inhibitors, calcium channel blockers, and alpha-adrenergic blockers probably offer a more favorable metabolic profile as compared with diuretics and beta-blockers. The former agents should be used as initial drugs in most clinical settings.

Estimates of the cost of diabetes should take into account the development of complications. Patient records identified from the 1987 National Hospital Discharge Survey were used to evaluate the risk of hospitalization due to late complications. Hospitalization for diabetic nephropathy reached a peak of 6.74/1000 between the ages of 45 and 54 years, compared to 0.14 to 1.80/1000 in controls. Diabetic patients less than or equal to 45 years of age were 46 times more likely to be hospitalized due to neuropathy. The risk of cardiovascular complications is high, with a greater incidence of arterial than venous disorders. Diabetic patients were 22 times more likely to be admitted for skin ulcers/gangrene, 15 times more likely due to peripheral vascular disease, and 10 times due to atherosclerosis. The risk of cerebrovascular accident and heart disease was 6 to 10 times greater in diabetic patients. Seventy-five per cent of diabetic cardiovascular disorders are myocardial infarction or chronic ischaemia. Hospitalization from renal complications occurs at younger ages than in the general population. Ophthalmic complications increase with age. Diabetic complications account for 2% of the total hospital admissions in the US in 1987. The total cost of the treatment of late diabetic complications was estimated at +5091 million (cardiovascular 74%; renal diseases 10%; nephropathy 3.6%; ophthalmic disorders 1.5%; other unspecified diseases 10%).

A population-based cohort study identified 915 deaths in 4186 patients with diabetes mellitus over a 5-year period. Ischaemic heart disease, cerebrovascular disease and malignant neoplasms were the major causes of death and accounted for 40%, 16%, and 14% of deaths, respectively, compared with 27%, 14%, and 25% of deaths in the non-diabetic population. Diabetic patients had a standardized mortality ratio (SMR) of 1.15 (95% Cl 1.08-1.22) (p less than 0.001). This excess risk of death was largely due to the excess death from ischaemic heart disease (SMR 1.55 (1.40-1.71); p less than 0.001) and the impact was greatest in middle-aged female patients. Stroke mortality was not significantly increased (SMR 1.09 (0.92-1.29)) while cancer mortality was reduced (SMR 0.75 (0.63-0.89); p less than 0.01). Death rates in diabetic male patients (SMR 1.04 (0.96-1.13)) did not differ significantly from those in non-diabetic male patients because the increased risk of ischaemic heart disease deaths (SMR 1.41 (1.22-1.62); p less than 0.001) was offset by the reduced risk of deaths from malignant neoplasms (SMR 0.65 (0.51-0.82); p less than 0.001). The reduction in cancer mortality did not reach statistical significance in diabetic women (SMR 0.82 (0.64-1.05)). Diabetic nephropathy and metabolic disasters were uncommon as causes of death.

Cardiac function was studied in 30 patients with insulin-dependent diabetes mellitus. Three groups, matched for age and diabetes duration, were defined as: group I (n = 10), normal urinary albumin excretion less than 30 mg 24 h-1; group II (n = 10), incipient diabetic nephropathy (urinary albumin excretion in the range of 30-300 mg 24 h-1); and group III (n = 10), clinical diabetic nephropathy (urinary albumin excretion greater than 300 mg 24 h-1). Ten non-diabetic subjects matched for sex and age served as controls. The left-ventricular end-diastolic volume measured by radionuclide cardiography was, at rest and during exercise, lower in group II and III compared with controls (p less than 0.05), while intermediate values were found in group I. The cardiac output was similar in the control group and group I; it was reduced, but not significantly so (p = 0.10), in group III and was significantly lower in group II (p less than 0.05). Stroke volume was also lower in group II and III than in controls (p less than 0.05), but not so in group I. These differences could not be explained by differences in metabolic control, blood pressure, blood volume status, degree of autonomic neuropathy or frequency of coronary heart disease. Our results might suggest that insulin-dependent diabetic patients with slightly but persistently elevated urinary albumin excretion have reduced diastolic compliance of the left-ventricle leading to impaired cardiac performance.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1979 to 1989, continuous ambulatory peritoneal dialysis (CAPD) was undertaken for terminal renal failure in 104 patients (56 women and 48 men; average age 54 +/- 15.3 years at the onset of dialysis), for a total observation period of 175 patients years. Survival rate for patients and methods and dialysis effectiveness were analysed retrospectively, the incidence of peritonitis prospectively, 40 patients were aged 60 years and over. Diabetic nephropathy was the most common cause of terminal renal failure (44%). Cumulative patient survival rate was 80% in the first year of treatment; 57% of patients were still alive after two years. The cause of death in 45 of the 54 patients who had died was unrelated to CAPD, cardiac disease and cerebrovascular accident being the most frequent causes (n = 26). During the first treatment year 47% of patients contracted bacterial peritonitis, 59% during the first two years. In 9% of patients CAPD had to be discontinued within the first two treatment years because of CAPD-related complications. There was no case of sclerosing peritonitis or of ultrafiltration loss forcing CAPD termination. These data indicate that there is no plausible explanation from a medical viewpoint for the highly restrictive use of CAPD in the Federal Republic of Germany.

The treatment of end-stage renal diabetic nephropathy remains a challenge. A large experience allows us to clearly outline the advantages and the drawbacks of continuous ambulatory peritoneal dialysis (CAPD) and continuous cyclic peritoneal dialysis (CCPD). Eighty-one patients, mean age 51.3 years, were treated over the last 9 years by CAPD-CCPD. Extrarenal complications, mainly vascular lesions, were present in this high-risk group of patients. The technique was modified in order to inject intraperitoneally, 4 times per day, insulin to control blood glucose level in CAPD patients. Actuarial survival was 92% at 1 year, 50% at 4 years mainly influenced by age: 85% survival at 2 years in 35 patients aged less than 50 years old and 62% at 2 years in 46 patients aged more than 50 years old. The main causes of death were of cardiovascular origin: myocardial infarction, stroke, atherosclerotic vasculopathy. The main causes of transfer to hemodialysis were due to technical complications. Peritonitis rate was one episode every 14 patient-months. Control of blood pressure, blood glucose levels, main biological parameters, and visual status were the clear advantages of the method. Peripheral vascular disease is not influenced by the technique. CAPD-CCPD is the technique of first choice in young diabetics and the preferential technique for home dialysis.

The traditional stepped-care approach to antihypertensive therapy, which progresses from simple low-dose monotherapy with diuretics and/or beta-blockers to complex combined regimens, is credited with reduction of hypertension-related stroke morbidity and mortality. However, it has achieved little success in reducing hypertension-related coronary morbidity and mortality. Overall mortality of treated hypertensive patients has remained higher than that of the general population, despite decreases in the blood pressure. In the 1990s, hypertension will be viewed as one of several cardiovascular risk factors requiring individualized treatment that takes concomitant diseases into account. Angiotensin converting enzyme (ACE) inhibitors that do not adversely affect serum lipid and glucose levels will play a major role. This class of drugs will also receive attention because of its beneficial action on diabetic nephropathy and its promising cardioprotective effect achieved by improved coronary blood flow, prevention of left ventricular hypertrophy and prevention of certain potentially life-threatening arrhythmias.

The treatment of end stage renal diabetic nephropathy remains a challenge. A large experience allows us to clearly outline the advantages and the drawbacks of continuous ambulatory peritoneal dialysis (CAPD). 81 patients, mean age 51.3 years, were treated over the past nine years by CAPD-CCPD. Extrarenal complications, mainly vascular lesions, account for qualifying these patients as a high risk population. The technique was modified in order to inject insulin intraperitoneally, four times per day, to control blood glucose level. Peripheral vascular disease was prospectively studied in 19 patients. Actuarial survival was 92% at one year, 50% at four years mainly influenced by age: 85% survival at two years in 35 patients aged less than 50 years and 62% at two years in 46 patients aged more than 50 years. The main causes of death were of cardiovascular origin: arteritis, myocardial infarction, stroke. The main causes for transfer to an alternative method of treatment were technical complications. Peritonitis rate was one episode ever 14 months. Satisfactory control of blood pressure, blood glucose levels, main biological parameters, visual status were the clear advantages of the method. Peripheral vascular disease is not influenced by the technique. CAPD can be the technique of first choice in young diabetics awaiting a kidney transplant and the reference technique for home dialysis.

Cardiovascular and Renal function were examined in two populations of long-term insulin-dependent diabetics, those with microalbuminuria, a sign of early, subclinical nephropathy and those with clinically manifest diabetic nephropathy. In addition, clinical variables of possible importance for the occurrence and prognosis of diabetic nephropathy were analyzed. Microalbuminuria - a mean of three over-night urinary albumin excretion rates greater than 20 micrograms/min - was found in 16% of Albustix-negative, normotensive, insulin-dependent diabetics. The microalbuminurics had higher supine blood pressures than normoalbuminurics. The albumin excretion rate in microalbuminurics correlated to blood pressure at rest but not to glycosylated haemoglobin. The cardiovascular responses to five different test manoeuvres revealed more evident signs of autonomic nerve dysfunction in microalbuminurics than in normoalbuminurics. The circulatory reactions during mental stress however, were almost identical in the two subgroups. Despite similar glomerular filtration rate and renal plasma flow the albumin excretion during mental stress increased in microalbuminurics, but remained unchanged in normoalbuminurics. It is postulated that a disturbance of glomerular basement membrane permeability is a pre-requisite for the elevated albumin excretion seen in microalbuminurics. Inability to regulate glomerular haemodynamics, due to autonomic nerve dysfunction, may also be a contributing factor. Such dysfunction perhaps even explains why microalbuminurics have higher blood pressures at rest compared with normoalbuminurics. In manifest diabetic nephropathy the rate of renal functional decline correlated to arterial blood pressure, while glycemic control showed no such relation. Patients with rapidly progressive nephropathy showed higher values of growth hormone than slow progressors. In patients with diabetic renal failure, cardiac catheterization revealed reduced stroke work and elevated left ventricular end-distolic pressure during exercise. Autonomic nerve dysfunction and arterial hypertension possibly contributed to the impaired cardiac performance. The existence of a specific diabetic cardiopathy must even be considered. There was a male predominance both in subclinical and manifest diabetic nephropathy. Age at onset of diabetes was lower in micro- as compared to normoalbuminurics. Duration of diabetes had no prognostic implication in subclinical or manifest nephropathy. The mortality rate was high in patients with manifest nephropathy.(ABSTRACT TRUNCATED AT 400 WORDS)
