Abstract

Most chronic nephropathies are characterized by a progressive decline in glomerular filtration rate (GFR) that may lead to renal function replacement by dialysis or transplant. Hypertension has an extremely important role among the various mechanisms contributing to renal function deterioration. High blood pressure levels are associated with increased urinary excretion of proteins and the decrease of systemic and glomerular hypertension reduces urinary excretion of proteins and preserves renal function deterioration. Moreover, recent studies found that an intensified blood pressure control (less than 130/80 mmHg) can slow the progression of diabetic and non diabetic renal disease even more than conventional blood pressure control. The Ramipril Efficacy in Nephropathy (REIN) Study showed that ramipril, an ACE-inhibitor, slowed the rate of GFR decline and halved the combined risk of doubling serum creatinine or end stage renal failure (ESRF) in patients with nephrotic range proteinuria as compared to conventional antihypertensive therapy, at comparable levels of blood pressure control. In these patients, prolonged enough treatment (at least 36 months) with ramipril, lowered the velocity of GFR decline and reduced the risk of dialysis. Thus, both tight blood pressure control and ACE-inhibitors may have a renoprotective effect. It will be interesting to evaluate whether the two combined approaches may have sinergistic effects.
