title: [Treatment of arterial hypertension in diabetic nephropathy. Certainties and hypotheses].
abstract: Clinical observation has long emphasized the importance of arterial hypertension in the course of diabetic nephropathy and recent studies suggest that hypertension might play a decisive pathogenetic role in the course of the disease, hence the necessity of correcting the hypertension of diabetic patients has by now been universally accepted. There is, however, still some uncertainty concerning the usefulness of acting preventively on so-called microhypertension; in other words, whether early antihypertensive drug treatment can prevent diabetic nephropathy. This paper discusses the criteria to be followed in the choice of antihypertensive medication during diabetic nephropathy giving special attention to pathophysiological considerations. Moreover, it also discusses the effects of antihypertensive drugs currently regarded as first-choice agents, i.e. calcium antagonists and the angiotensin converting enzyme inhibitors, on intrarenal hemodynamics.
