Overview

I am a nephrologist at Duke University with over 20 years of experience as a clinician, clinical researcher, and mentor. In my outpatient practice, I take care of patients with chronic kidney disease (CKD). In my hospital work, I evaluate and care for patients with acute kidney injury and with electrolyte disorders. In clinical research, I am experienced in serving on steering committees for multicenter clinical trials in CKD, including work with National Institutes of Health (NIH)-funded trials -- the African American Study of Kidney Disease and Hypertension (AASK), the AASK Cohort Study, the Dialysis Access Consortium, and the Focal Segmental Glomerulosclerosis (FSGS) treatment trial. I recently joined the steering committee for the NIDDK consortium, pilot studies of candidate therapies for CKD. I am active in multiple industry-sponsored clinical trials. I am a member of the executive committee for the Collaborative Study Group, a consortium that has implemented several successful clinical trials in nephrology.

Dr. Middleton is rated as an Advanced provider by MediFind in the treatment of High Potassium Level. His top areas of expertise are Chronic Kidney Disease, End-Stage Renal Disease (ESRD), High Potassium Level, and Autosomal Dominant Polycystic Kidney Disease.
