Study protocol. Study protocol. Fourteen patients had research renal biopsies, and 17 patients with macroalbuminuria had renal biopsies for clinical reasons. As part of the study protocol, after ceasing RAS inhibitor therapy for 4–6 weeks prebiopsy, 2 out of 10 patients with normoalbuminuria developed microalbuminuria (“pseudonormoalbuminuria”), making the total number of patients with normoalbuminuria eight and with microalbuminuria six.
