Importance of blood pressure control in chronic kidney disease
No full textArterial hypertension together with proteinuria is one of the most important factors associated with the progression of both diabetic and nondiabetic chronic kidney disease. In this review, the role of hypertension and proteinuria in renal disease progression, the BP target that should be achieved to slow the progression of renal damage, and the influence of baseline and current proteinuria on the renoprotective effects of antihypertensive therapy are discussed thoroughly. The interaction between the renoprotective effects of specific antihypertensive agents--mostly angiotensin-converting enzyme inhibitors and angiotensin receptor blockers--and the level of achieved BP also are evaluated. The body of evidence provided by several studies emphasizes the importance of both lowering BP and inhibiting the renin-angiotensin system as specific goals for renal and cardiovascular protection in chronic kidney diseas
Optimizing therapy in the diabetic patient with renal disease: antihypertensive treatment.
No full textEmerging therapeutic strategies in diabetic nephropathy
No full textDiabetic nephropathy is one of the main causes of end-stage renal disease (ESRD) and is associated with elevated cardiovascular morbidity and mortality. Current renoprotective treatment for diabetic nephropathy includes strict glycemic and optimal blood pressure control, proteinuria/albuminuria reduction and the use of renin-angiotensin-aldosterone system (RAAS) blocking agents. However, the renoprotection provided by these treatments is only partial, and many patients still have progressive disease, thus suggesting that a more effective approach is urgently needed. This review examines emerging strategies for the treatment of diabetic nephropathy, including aggressive RAAS blockade, statins, pentoxifylline, glitazones, ruboxistaurin, as well as sulodexide. Pilot studies that used surrogate end points, mainly albuminuria, will be discussed. New insights suggest that treating microalbuminuric diabetic patients with statins, pentoxifylline, glitazones and sulodexide could be a new approach for reducing the incidence of clinical proteinuria. In diabetic patients with overt nephropathy, the administration of statins, pentoxifylline, sulodexide or aggressive RAAS inhibition, including RAAS dual blockade (i.e., angiotensin-converting enzyme [ACE] inhibitors plus angiotensin receptor blockers or aldosterone antagonists plus ACE inhibitors or angiotensin receptor blockers), seems to be a promising way to preserve renal function and to prevent progression to ESRD. Results of ongoing, long-term trials on major renal and cardiovascular clinical outcomes, as well as on mortality are needed to establish whether the current standard of care of diabetic nephropathy might be improved with these new strategie

The role of angiotensin II AT1-receptor antagonists in renal and cardiac protection in type-2 diabetes mellitus
No full textBlood pressure reduction and intensive antihypertensive treatment are effective in reducing both microvascular and macrovascular complications in type 2 diabetes. Blood pressure target levels < 130/85 or 130/80 mmHg are now recommended. Antagonism of the renin-angiotensin-aldosterone system seems to be an important goal in the treatment of hypertension and diabetes-related complications. The renoprotective role of angiotensin-converting enzyme (ACE)-inhibitors has been well documented in type 1 diabetes; in type 2 diabetes ACE-inhibitors have been deemed more effective than other traditional drugs in reducing the onset of overt nephropathy in microalbuminuric patients (secondary prevention) but not in reducing renal dysfunction in patients with clinical proteinuria (tertiary prevention). Recently, four large trials performed on type 2 diabetes showed that angiotensin II receptor blockers (ARBs) prevent the development of clinical proteinuria in microalbuminuric patients (IRMA and MARVAL studies) and delay the progression of nephropathy towards end-stage renal failure in patients with overt nephropathy (IDNT and RENAAL studies). Moreover, ARBs have been deemed more effective in reducing hospitalizations for heart failure compared to placebo (IDNT and RENAAL studies) and in reducing cardiovascular morbidity and mortality compared to conventional therapy (LIFE study) in type 2 diabetes. In conclusion, ARBs are effective in preventing and delaying renal damage in type 2 diabetes. Thus, the recent guidelines for the prevention and treatment of diabetic nephropathy state that ACE-inhibitors are the first-choice drugs in type 1 diabetes while ARBs are considered as the first-choice drugs in secondary prevention, the same as ACE-inhibitors, and are the unique first-choice drug in tertiary prevention of end-stage renal failure in type 2 diabetes. Finally, ACE-inhibitors and ARBs are both first-choice drugs in cardiovascular prevention in type 2 diabete
