At Hopkins GIM, our faculty are investigating several different aspects of the CKD epidemic, including: (1) genetics of CKD; (2) natural history of CKD and transition to renal failure; (3) screening for CKD in the general population; (4) optimal treatment to prevent progression; (5) optimal regime once renal replacement therapy is required; and (6) epidemiology and prevention of vascular complications in end-stage renal disease.
