THURSDAY, March 6, 2025 -- GLP-1 drugs like Ozempic can help kidney transplant patients avoid organ failure and live longer, a new study suggests. The drugs help manage patients’ type 2 diabetes and promote weight loss, both of which improve the chances of a successful kidney transplant, researchers added. Kidney transplant patients prescribed GLP-1 drugs were 49% less likely to experience organ failure, in which their new kidney stops working and they have to resume dialysis, researchers reported March 3 in The Lancet . Patients taking GLP-1 drugs also had a 31% lower risk of dying within five years of starting on the medication, researchers said. “Our study results are the strongest evidence to date that GLP-1 agonist drugs are largely safe and effective tools for addressing type 2 diabetes in kidney transplant recipients,” lead researcher Dr. Babak Orandi said in a news release. He's a transplant surgeon and obesity medicine specialist at NYU Langone Health in New York City. Glucagon-like peptide-1 (GLP-1) drugs mimic the GLP-1 hormone, which helps control insulin and blood sugar levels, decreases appetite and slows digestion of food. GLP-1 drugs include semaglutide, liraglutide and dulaglutide, now marketed as Ozempic , Wegovy , Saxenda , Victoza and Trulicity . Both diabetes and obesity increase the risk of a kidney transplant going bad, researchers said. Given that, it makes sense that GLP-1 drugs might help. However, known side effects of the drugs include inflammation of the pancreas and liver problems, which might work against a kidney transplant, researchers noted. There’s also been concern that GLP-1 drugs might increase the risk of a rare form of thyroid cancer in patients taking immune-suppressing drugs to prevent transplant rejection, researchers added. To check the risks and benefits of the drugs, researchers reviewed the medical records of more than 18,000 kidney transplant recipients with diabetes between 2013 and 2020. Of those, more than 1,900 had been prescribed a GLP-1 drug. Although the study found benefits, it also discovered some increased risks associated with the drugs. Kidney transplant patients taking GLP-1 drugs had a 49% greater risk of developing diabetic retinopathy, a potentially blinding condition caused by damage to the light-sensitive tissue lining the back of the eyes. “Our findings also show that while the benefits of GLP-1 drugs are significant, their use does come with some added risk of diabetic retinopathy, suggesting that physicians need to carefully monitor the eye health of kidney transplant recipients with diabetes who are started on these drugs,” senior investigator Mara McAdams-DeMarco said in a news release. She is an associate professor of surgery and population health at NYU Grossman School of Medicine. Orandi said this risk can be managed by screening for diabetic retinopathy in transplant patients, particularly in people with uncontrolled diabetes, and making sure blood sugar levels are stable before prescribing GLP-1 drugs. Doctors also might consider starting with lower doses of GLP-1 drugs and slowly increasing them for people with severe diabetes or a history of eye problems, he added. More research is needed to figure out exactly why GLP-1 drugs might help kidney transplants succeed, as well as why they increase the risk of diabetic retinopathy, researchers concluded.

-Drugs found to be safe and effective overall despite some risk of eye damage NEW YORK, March 5, 2025 /PRNewswire/ -- Kidney transplant recipients with type 2 diabetes treated with a new class of anti-obesity drugs were less likely to experience organ failure and survived longer, a new study shows. Not only is obesity a known risk factor for diabetes, but it also increases risk of postsurgical complications, such as inflammation, organ rejection, and early death. Previous research had suggested some benefit for kidney transplant recipients with a history of type 2 diabetes who took the medications, originally designed to treat diabetes, at some point after their transplant and then experienced slower declines in kidney function than those who did not. These GLP-1 agonists include semaglutide, liraglutide, and dulaglutide, now marketed as Ozempic, Wegovy, Saxenda, Victoza, and Trulicity. It remained unclear, however, whether physicians should prescribe the drugs, given their known side effects, which include inflammation in the pancreas and liver problems. There had also been concern that GLP-1 agonists might increase the risk for a rare form of thyroid cancer in patients already taking immune-suppressing drugs to prevent transplant rejection, a condition where the body's immune system attacks the transplanted kidney as it would a foreign virus or bacteria. Led by researchers at NYU Langone Health, the new study showed that those who were prescribed GLP-1 agonists, mostly within three years of receiving their transplant, were 49% less likely to experience organ failure — when the transplanted kidney stops functioning, and the patient has to resume dialysis — than those who had not been prescribed a GLP-1. Kidney transplant recipients taking the medications also had a 31% reduced risk of dying within five years of their starting on the medication, compared to those who did not take the drugs. While risk for inflammation in the pancreas, liver problems, or thyroid cancer was not found to be higher in the patients with diabetes treated with GLP-1s, the study did show the treated group had a 49% greater chance of developing diabetic retinopathy. This potentially blinding damage to the light-sensitive tissue lining the back of the eyes often accompanies diabetes when blood sugar levels are not under control. "Our study results are the strongest evidence to date that GLP-1 agonist drugs are largely safe and effective tools for addressing type 2 diabetes in kidney transplant recipients," said study lead investigator, transplant surgeon, and obesity medicine specialist Babak Orandi, MD, PhD. "Our research offers a large amount of real-world clinical data to guide the management of benefits and risks of GLP-1 use in kidney transplant recipients," said Orandi, an associate professor in the Departments of Surgery and Medicine at NYU Grossman School of Medicine. Publishing in the journal The Lancet Diabetes and Endocrinology online March 5, the study was designed to clarify the value and safety of the drugs. Researchers reviewed the medical records of 18,016 kidney transplant recipients with pretransplant diabetes in the United States between 2013 and 2020, of whom 1,916 were prescribed GLP-1s. "Our findings also show that while the benefits of GLP-1 drugs are significant, their use does come with some added risk of diabetic retinopathy, suggesting that physicians need to carefully monitor the eye health of kidney transplant recipients with diabetes who are started on these drugs," said study senior investigator and epidemiologist Mara McAdams-DeMarco, PhD. McAdams-Demarco is an associate professor in the Departments of Surgery and Population Health at NYU Grossman School of Medicine. People with diabetes lose the ability to produce or efficiently use insulin, the hormone produced by the pancreas and needed to regulate the body's blood sugar and energy levels. Because diabetic retinopathy, the leading cause of blindness in the United States, can occur in people whose blood sugar levels are corrected too quickly, Orandi says the key to managing its risk is to screen for diabetic retinopathy, particularly in people with uncontrolled diabetes, and make sure that blood sugar levels are under control prior to taking GLP-1s. He also suggests slowly adjusting GLP-1 doses from small to large (titrating) in kidney transplant recipients with severe diabetes or in patients with a history of eye problems. Among the study's other findings was that GLP-1 users were more likely to be younger, female, Black, and poor than those who were not prescribed the medications. For the study, researchers used data from the U.S. Renal Data System, which integrates data from the Organ Procurement and Transplantation Network that allocates organ transplantation across North America, the U.S. Centers for Medicare and Medicaid Services, and Medicare claims data, including information on prescription drug use. More research is needed, the researchers say, into the biological mechanisms behind GLP-1 agonists and how they improve kidney health posttransplant. Type 2 diabetes is among the leading causes of end-stage kidney disease, the primary cause for a quarter-million Americans now awaiting a kidney transplant.
