Researchers Identify Promising Treatment for Inherited Form of Kidney Disease

A promising drug therapy for an inherited form of kidney disease has been discovered by Mayo Clinic researchers. The medication, tolvaptan, slowed the pace of kidney cyst growth over the three years of the study.

The multicenter study found tolvaptan demonstrated a nearly 50 percent reduction in the rate of increase in total kidney volume (a measurement of kidney cyst growth) in ADPKD patients over the study period, compared to placebo.

Acute Renal (Kidney) Failure- Causes, Symptoms, Diagnosis, Treatment and Complications
Acute renal failure is the sudden cessation of the functioning of kidneys, that can be due to reduced renal blood flow, damage to renal tissues.

"ADPKD is the most common inherited and the fourth most common overall cause of kidney failure worldwide," said lead author Vicente Torres, M.D., Ph.D., Mayo Clinic nephrologist.

"In most patients with this disease, relentless cyst growth within the kidneys destroys the tissue, causes hypertension and painful complications, and negatively impacts the quality of life.

"The results of this study reveal a potential treatment that blunts kidney growth, lessens associated symptoms and slows kidney function decline when given over three years," Dr. Torres added.

Quiz on Kidney Stones
Kidney stones or calculus produces the most severe form of pain in humans. The pain has often been described to be worse than childbirth, broken bones, gunshot wounds, burns, or surgery. Once you form a kidney stone you are always susceptible to another stone. Take this quiz to find out how much do you know about stone disease. Once you complete find out how you fared compared to others who have taken the quiz.

While the trial findings are encouraging, tolvaptan has not yet been approved for this indication, Dr. Torres noted.

The phase three clinical trial results were being presented today at the American Society of Nephrology annual meeting and published online in the New England Journal of Medicine.
