Additional Relevant Details
The data showed that plasma levels of intact parathyroid hormone (iPTH) continued to fall as serum levels of 25-hydroxyvitamin D (25D) rose above 30 ng/mL, a level considered sufficient for CKD patients in published clinical practice guidelines. These data suggest that patients with stage 3 or 4 CKD require higher levels of serum 25D than previously thought in order to control elevated iPTH.OPKO's poster presentation entitled "Modified-release Calcifediol Treatment of SHPT Indicates That Higher Than Expected Serum 25D Levels May Be Required in Subjects With CKD," will be presented by senior author Stuart M.
