Arterial hypertension and proteinuria in pediatric chronic kidney disease

Abstract

A variety of chronic kidney diseases tend to progress towards end-stage kidney disease. Progression is largely due to factors unrelated to the initial disease, including arterial hypertension and proteinuria. Intensive treatment of these two factors is potentially able to slow the progression of kidney disease. Blockers of the renin-angiotensin-aldosterone system, either converting enzyme inhibitors or angiotensin II receptor antagonists, reduce both blood pressure and proteinuria and appear superior to a conventional antihypertensive treatment regimen in preventing progression to end-stage kidney disease. The most recent recommendations state that in children with chronic kidney disease without proteinuria the blood pressure goal is the corresponding 75th centile for body length, age and gender; whereas the 50th centile should be aimed in children with chronic kidney disease and pathologically increased proteinuria.
