How taking blood pressure medication can lead to kidney damage
![Kidney image. About 80% of chronic kidney disease patients actually die from cardiovascular complications. Although the link between these diseases is well established, the actual biological mechanism involved has not been fully understood. But researchers at Temple University recently uncovered a key piece to this connection, where chronic kidney disease and high-fat diets combine to trigger blood vessel inflammation. Their findings are published online in Redox Biology.[1]](/sites/default/files/styles/top_stories/public/assets/articles/Kidney-Renal.jpg.webp?itok=MTRIpWbW)
The long-term use of medications commonly prescribed treat high blood pressure may cause kidney damage, according to new research published in JCI Insight.
The study's authors noted that medications such as ACE inhibitors and angiotensin receptor blockers have all been associated with hardened kidney vessels, which can lead to permanent organ damage.
“Our studies show that renin-producing cells are responsible for the damage,” co-author Maria Luisa Sequeira Lopez, MD, of the University of Virginia (UVA) department of pediatrics, said in a prepared statement. “We are now focusing on understanding how these cells, which are so important to defend us from drops in blood pressure and maintain our well-being, undergo such transformation and induce kidney damage. What is needed is to identify what substances these cells make that lead to uncontrolled vessel growth.”
Lopez and colleagues noted that patients should keep taking their medications as normal. However, they see a definite need for more research in this area.
“It would be important to conduct prospective, randomized controlled studies to determine the extent of functional and tissue damage in patients taking medications for blood pressure control,” co-author Ariel Gomez, MD, also from UVA’s department of pediatrics, said in the same statement. “It is imperative to find out what molecules these cells make so that we can counteract them to prevent the damage while the hypertension is treated with the current drugs available today.”
