[Nephrology update. Kidney protection with antihypertensive drugs: I].
Diabetes has become the most common single cause of end-stage renal disease in many countries. The coexistence of diabetes mellitus and hypertension dramatically increases the risk of developing target organ complications including renal disease. There are good arguments that ESRD in the patient with diabetes is largely preventable with the interventions currently available. For type 2 diabetes the UK Prospective Diabetes Study Group Trial clearly documented that the frequency of microangiopathic sequelae can be diminished by glycaemic control and even more impressively by intensified antihypertensive treatment. An analysis of recent randomized long-term clinical trials that evaluated the rate of decline in renal function demonstrated that the lower the blood pressure within the range of normotensive values, the greater the preservation of renal function. Since the 1994 Working Group Report on Hypertension and Diabetes suggested a goal blood pressure of 130/80 mmHg should be achieved in patients with diabetes and/or renal insufficiency; lower blood pressure levels, i.e. less than 125/75 mmHg are recommended for patients with proteinuria > 1 g/d and renal insufficiency regardless of etiology. Antihypertensive regimens should include an ACE inhibitor or an AT1-receptor blocker in order to provide maximum renal benefits in diabetic and non-diabetic renal diseases. Such low blood pressure are virtually impossible to achieve with monotherapy. In most cases the combination of two and more antihypertensive drugs is necessary. The purpose of this report is to update the previous recommendations with a focus on level of blood pressure control, proteinuria reduction and retarding the progression of renal disease.
