Study checks if past drug still protects kidneys years later

This study looks at American Indians with type 2 diabetes who had early kidney disease and took a drug called losartan years ago. Researchers want to see if the benefits of that treatment still help protect their kidneys today. About 141 people who were in the earlier study or their relatives with diabetes can join. No new treatment is given—only tests like blood draws, urine samples, and kidney scans.
