Plasma glucose determinations continue to be at the heart of the proper diagnosis and monitoring of diabetes mellitus, the post-prandial values in particular being of decisive importance for the diagnosis. Laboratory diagnostic investigations going beyond this (e.g. the oral glucose tolerance test) are reserved for special indications. In contrast, the determination of microalbuminuria is of increasing importance for deciding on the next therapeutic steps. Prerequisites for successful treatment are patient instruction, treatment of the metabolic disorder including diet and physical exercise, and self-monitoring by the patient. Of fundamental importance for treatment is the diet, with calorie reduction in type 2 diabetics, most of whom are obese.

Renal disease in elderly diabetic patients is costly in terms of morbidity, mortality and medical payments. Therefore, prevention of diabetic nephropathy has become a prominent goal in the treatment of diabetic patients. Preventive treatment should begin not later than at the stage of persistent microalbuminuria, and regular screening for microalbuminuria is recommended for both elderly and younger diabetic patients. Improved metabolic control, through diet and hypoglycaemic therapy, has been demonstrated to lower urinary albumin excretion. The target level of glycated haemoglobin is < 8%, or < 2% higher than the upper limit of normal in nondiabetic people. Insulin therapy has no adverse effects on renal indices, unless it increases bodyweight and consequently raises blood pressure. To preserve renal function in elderly diabetic patients, blood pressure should be kept well below 140/90 mm Hg. Treatment with ACE inhibitors may be the 'gold standard' intervention, and should be initiated at the lowest possible dosage and then titrated until the maximum tolerated dosage has been reached. Nonchronotropic calcium antagonists have been shown to be as effective as ACE inhibitors with regard to their effects on blood pressure, renal haemodynamics and urinary albumin excretion. Most dihydropyridines have been found to increase or to have no effect on urinary albumin excretion despite significant blood pressure reduction. A renoprotective action of diuretics is generally unlikely, with the possible exception of indapamide. Although beta-blockers are effective antihypertensive agents, they may not adequately preserve kidney function in diabetic patients. Because beta-blocker treatment may mask the symptoms of hypoglycaemia, they should be reserved for patients with coronary artery disease or arrhythmias.

Approximately 150 million people worldwide have diabetes mellitus, of whom 90% are type II diabetics. It is therefore of no surprise that diabetic nephropathy has become the leading cause of end-stage renal disease. Opposite to what has been known previously, kidney disease is at least as common in type II as in type I diabetes. However, because the majority of type II diabetics has hypertension for many years before diabetes mellitus becomes clinically relevant, renal lesions are often heterogeneous with frequent exclusive presence of ischemic changes. For the treatment of hypertension in diabetics without nephropathy (no microalbuminuria), drugs that exert beneficial effects or are at least neutral with respect to lipid and glucose metabolism, such as ACE inhibitors, angiotensin II-receptor antagonists, non-dihydropyridine-calcium channel blockers and the thiazide-like indapamide, are to be preferred. Although metabolically neutral, dihydropyridine calcium channel blockers should be used with caution, since an increase in cardiovascular morbidity and mortality in type II diabetics treated with these compounds has most recently been described. Once that diabetic nephropathy is established, blood pressure should be lowered to 120/80 mmHg (measured in seated position). Antihypertensive treatment should primarily be based on ACE inhibitors; angiotensin II-receptor antagonists are a valuable alternative if ACE inhibitors are not tolerated. Both ACE inhibitors and angiotensin II-receptor antagonists should be used with high caution in elderly patients with severe atherosclerosis in whom acute renal failure could occur due to the presence of bilateral renal artery stenosis. Newer studies indicate that non-dihydropyridine calcium channel blockers such as verapamil and diltiazem may be as effective as ACE inhibitors in preserving renal function in diabetic nephropathy. A fix-dose combination of the ACE inhibitor trandolapril with verapamil is now available; it should be reserved for patients whose blood pressure and/or proteinuria can not be adequately controlled with ACE inhibitors. Finally, indapamide is the only antihypertensive diuretic with nephroprotective properties.

Recent trials have helped to clarify indications for the initial pharmacological therapy of hypertension. Both the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) and World Health Organization-international Society of Hypertension (WHO-ISH) recommendations should be revised. The more recent trials indicate that: (1) diuretics and beta-blockers appear to be as effective in reducing overall morbidity/ mortality as other agents (Swedish Trial in Old Patients with Hypertension [STOP-2], United Kingdom Prospective Diabetes Study [UKPDS], Intervention as a Goal in Hypertension Treatment [INSIGHT], Nordic diltiazem [NORDIL]); (2) the use of an a-blocker results in more cardiovascular events, especially congestive heart failure, when compared with a diuretic (Antihypertensive Therapy and Lipid Lowering Heart Attack Trial [ALLHAT]); (3)the use of an angiotensin-converting enzyme (ACE) inhibitor results in fewer myocardial infarctions and episodes of heart failure than calcium channel blockers in the elderly and in diabetic patients (Fosinopril vs. Amlodipine Cardiovascular Events Randomized Trial [FACET], Appropriate Blood Pressure Control in Diabetes [ABCD], STOP-2) - other data (Captopril Prevention Project [CAPPP]) suggest that the use of an ACE inhibitor is preferred in diabetic patients; (4) overall cardiovascular events are similar with calcium channel blockers compared with a diuretic - however, there are fewer strokes with non-dihydropyridine calcium channel blockers (NORDIL) and a trend towards an increase in heart failure and myocardial infarctions with either a dihydropyridine or non-dihydropyridine calcium channel blockers compared with a diuretic (INSIGHT, NORDIL); (5) angiotensin receptor blockers (ARBs) will decrease proteinuria and slow progression of renal disease in type 2 diabetic patients when compared with regimens that do not include an ARB or an ACE inhibitor (Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan [RENAAL], Irbesartan Type II Diabetic Nephropathy Trial [IDNT], Irbesartan Type II Diabetes with Microalbuminuria [IRMA Il]). The debate over initial therapy may be moot. High-risk hypertensive patients should probably be treated initially with combination therapy, one of which should be a diuretic. The use of diuretics and beta-blockers as well as ACE-inhibitors alone or with a diuretic should be considered as initial therapy (a change from JNCVI). Alpha-blockers should be reserved for special situations, i.e. prostatic hypertrophy (in contrast to WHO-ISH recommendations). An ACE-inhibitor or ARB, usually along with a diuretic, can be considered as preferred therapy in hypertensive diabetic patients. Some data suggest equal or greater reduction in strokes with a calcium channel blocker than other medications.
