Popular diabetes and obesity drugs also protect kidneys, study shows

The largest and most complete evaluation of glucagon-like peptide-1 (GLP-1) receptor agonists on kidney and cardiovascular outcomes exhibits they’ve vital advantages in folks with and with out diabetes. The findings have been printed in The Lancet Diabetes & Endocrinology.

Initially developed to deal with diabetes, GLP-1 receptor agonists mimic the motion of a hormone referred to as glucagon-like peptide 1, which stimulates insulin manufacturing and lowers blood sugar ranges. Extra just lately, they’ve emerged as efficient therapies for weight problems—slowing digestion, growing emotions of fullness, and decreasing starvation.

However whereas the advantages of GLP-1 receptor agonists for the therapy of sort 2 diabetes, weight problems and heart problems are well-known, their influence on power kidney illness (CKD) has been much less sure.

Researchers carried out a meta-analysis of 11 large-scale medical trials of GLP-1 receptor agonists involving a complete of 85,373 folks (67,769 folks with sort 2 diabetes and 17,604 folks with chubby or weight problems and heart problems however with out diabetes).

Seven totally different GLP-1 receptor agonists have been investigated among the many trials, together with semaglutide (also referred to as Ozempic or Wegovy), dulaglutide (Trulicity) and liraglutide (Victoza).

The outcomes confirmed that in comparison with placebo, GLP-1 receptor agonists decreased the danger of kidney failure by 16% and the worsening of kidney operate by 22% (outlined by a drop in estimated glomerular filtration charge—a measure of how a lot blood the kidneys filter clear each minute—of a minimum of 50%). The mixed discount within the threat of kidney failure, worsening kidney operate, and dying resulting from kidney illness was 19%.

The evaluation additionally confirmed earlier findings that GLP-1 receptor agonists defend cardiovascular well being, with a 14% discount within the threat of cardiovascular dying, non-fatal coronary heart assault, and non-fatal stroke, in comparison with placebo. Demise by any trigger was 13% decrease amongst sufferers handled with GLP-1 receptor agonists.

Lead writer Professor Sunil Badve, Professorial Fellow at The George Institute for World Well being and UNSW Sydney stated the research expanded present information about this class of medicine in key areas, together with advantages in folks with CKD, and in folks with and with out diabetes.

“That is the primary research to indicate a transparent advantage of GLP-1 receptor agonists on kidney failure or end-stage kidney illness, suggesting they’ve a key function in kidney-protective and heart-protective therapy for sufferers with widespread medical situations like sort 2 diabetes, chubby or weight problems with heart problems, or CKD,” he stated.

“These outcomes are significantly essential for sufferers with power kidney illness. It’s a progressive situation finally resulting in kidney failure requiring dialysis or kidney transplantation and is related to untimely dying, largely from coronary heart illness. It has a major influence on sufferers’ high quality of life and incurs substantial well being care prices.”

CKD is estimated to have an effect on one in 10 folks worldwide, equal to round 850 million folks. It’s the tenth main explanation for dying and is projected to change into the fifth commonest explanation for dying by 2050. Diabetes, heart problems and weight problems are unbiased threat elements for CKD and symbolize a significant international well being burden.

Professor Vlado Perkovic, Professorial Fellow at The George Institute, Provost at UNSW Sydney and senior writer on the research stated, “This analysis exhibits that GLP-1 receptor agonists may play an essential function in addressing the worldwide burden of non-communicable ailments. Our research may have a significant influence on medical tips for the administration of power kidney illness and heart problems in folks with and with out diabetes.

“Extra work is now wanted to implement the outcomes of this research into medical observe and enhance entry to GLP-1 receptor agonists to individuals who will profit from them.”
