Zusammenfassung
Der Nephropathieverlauf wird durch zahlreiche beeinflussbare Faktoren moduliert. In der Primärprävention vermindert eine normnahe Stoffwechselführung von Diabetesbeginn an das Risiko der Mikroalbuminurieentwicklung in Abhängigkeit vom erreichten HbA1c-Wert. Hypertensive Diabetiker sollten mit RAS-blockierenden Substanzen konsequent behandelt werden. Bei bereits bestehender Nephropathie kann eine multifaktorielle Therapie die weitere Progression verhindern oder zumindest verzögern. Dazu gehören eine konsequente Blutdrucksenkung in den normotensiven Bereich unter Verwendung von RAS-blockierenden Substanzen (auch bei noch normotensiven Patienten) sowie eine möglichst normnahe Stoffwechselführung unter Beachtung der bei Niereninsuffizienz veränderten Pharmakokinetik und -dynamik der blutzuckersenkenden Substanzen. Die Beeinflussung weiterer Faktoren (Rauchen, Eiweißaufnahme, Anämie) und die Beachtung allgemein nephroprotektiver Maßnahmen ergänzen das Behandlungsspektrum. Wegen der hohen kardiovaskulären Morbidität haben Lipidsenkung oder ASS-Gabe wesentliche Bedeutung. Ein engmaschiges Monitoring der Nierenfunktion und der Therapiefaktoren ist unerlässlich.
Abstract
The course of diabetic nephropathy is affected by several factors that can be manipulated. In primary prevention, near normal metabolic control beginning at the time of the diagnosis of diabetes diminishes the risk of microalbuminuria to an extent depending on the HbA1c level attained. Hypertensive diabetics should be consistently treated with renin-angiotensin system (RAS)-blocking agents. In secondary prevention, a multifactorial therapy is able to stop or retard further progression. Its components are a sustained decrease of blood pressure in the normotensive range using RAS-blocking agents (normotensive patients should also be treated) as well as near normal metabolic control that takes into account the changing pharmacokinetic and pharmacodynamic properties of blood glucose-lowering drugs in renal insufficiency. Consideration of further factors (smoking, protein intake, anemia) and several general nephroprotective measures complete the treatment spectrum. Therapy for dyslipidemia and the administration of aspirin are important in view of the high cardiovascular morbidity. It is essential to monitor kidney function and the therapeutic components at short intervals.
