Does having metabolic syndrome increase the risk of rejection in kidney transplant recipients?
Metabolic syndrome is a cluster of conditions including high blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol levels. In kidney transplant recipients, this condition is often caused by the side effects of immunosuppressive drugs. Research shows that having metabolic syndrome significantly raises the risk of acute graft rejection, which happens when the immune system attacks the new kidney.
What the research says
A large review of 15 studies involving nearly 9,000 kidney transplant recipients found that those with metabolic syndrome had a much higher risk of acute graft rejection compared to those without it 2. The same review showed that metabolic syndrome also increased the risk of major heart events and death 2.
While some trials test new drugs to prevent rejection, such as a study combining dazodalibep and belatacept, these studies focus on drug safety and rejection rates rather than the specific impact of metabolic syndrome on those outcomes 1. However, other research suggests that metabolic issues like cardiovascular disease and gut inflammation are linked to graft failure 3.
What to ask your doctor
- How does my current level of metabolic syndrome affect my risk of kidney rejection?
- What lifestyle changes can I make to lower my metabolic syndrome and protect my new kidney?
- Are there specific medications I should take to manage my blood pressure or blood sugar to prevent rejection?
- How often should I get tests to check for signs of metabolic syndrome in my new kidney?
