The role of the renin\u2013angiotensin system (RAS) blockade in this disorder remains uncertain.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>We conducted a retrospective analysis involving 20 admitted patients who received aliskiren, a direct renin inhibitor (DRI), for the management of hypertensive emergency associated with elevated plasma renin activity (PRA). We analyzed the changes in blood pressure (BP), kidney function, and RAS activity in the subacute and chronic phases.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The use of DRI was associated with a marked reduction in PRA (median, from 25.0 to 1.2 ng\/ml\/h) and serum aldosterone levels (from 404 to 130 pg\/ml) during the index admission. BP also decreased from 226\/143 to 142\/80 mm Hg. A comparison of clinical characteristics according to the renal function indicated that dialysis-dependent patients had higher aldosterone levels than non-dialysis-dependent patients at admission, despite comparable BP levels. After a median follow-up of 567 days in non-dialysis-dependent patients with DRI, eGFR levels were significantly increased from 14.3 to 23.1 ml\/min\/1.73 m2. PRA levels were consistently suppressed at 0.8 ng\/ml\/h. We found a significant correlation between the degree of PRA suppression and changes in eGFR (r\u2005=\u2005\u20130.58), indicating that the effective blockade of RAS is associated with the preservation of eGFR in the study subjects.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>DRI can successfully suppress PRA in patients with high-renin hypertensive emergency in both subacute and chronic phases.
