Meds like Ozempic could ease arthritis

Ozempic’s cardinal constituent whitethorn enactment straight connected cartilage to repair creaky joints.

In mice and people, semaglutide tin ease symptoms of nan associated illness osteoarthritis and thicken nan cartilage pillowed betwixt bones, researchers study February 9 successful Cell Metabolism.

Thicker cartilage suggests nan insubstantial is being rebuilt, says Di Chen, a expert and biologist astatine Shenzhen University of Advanced Technology successful China. “That’s a bully thing,” he says. “That’s nan cardinal thing.” More cartilage intends much cushion, which intends little bone-on-bone grinding and little pain.

Osteoarthritis is nan astir communal shape of arthritis, affecting much than 500 cardinal group worldwide. The illness tin impact nan hands, knees, hips and different joints, causing terrible symptom arsenic cartilage wears distant and tissues inflame. There’s nary cure, and nary medications that forestall it from becoming worse. Doctors tin only thief patients effort to negociate pain, Chen says.

Scientists deliberation weight nonaccomplishment tin thief alleviate symptoms by reducing nan load connected joints. That’s why semaglutide, nan smash weight nonaccomplishment supplier successful Ozempic and Wegovy, is considered a contender for osteoarthritis treatment. And indeed, successful 2024, a objective proceedings successful group pinch obesity reported that nan supplier  improved associated symptom and function. Doctors assumed those benefits were owed to weight loss, Chen says. His squad wasn’t truthful sure.

The researchers conducted a akin study successful mice pinch a shape of osteoarthritis. One group received semaglutide, nan different did not. In nan drug-free mice, Chen’s squad restricted nutrient intake to lucifer that of nan semaglutide group. Both groups shed weight, but only nan treated mice saw joint-based benefits. These mice had little pain, little broken-down cartilage and much cartilage growth, nan squad found. The results propose that weight nonaccomplishment isn’t driving semaglutide’s benefits.

Chen’s squad saw echoes of those results successful a mini objective proceedings successful obese group pinch knee osteoarthritis. After six months connected a debased dose of semaglutide positive hyaluronic acid, a lubricant made by nan body, participants’ knee usability improved. This could beryllium owed to plumped-up cartilage. MRI exams revealed a 17 percent summation successful cartilage thickness successful group connected semaglutide. That’s compared pinch a little than 1 percent summation successful group connected conscionable hyaluronic acid.

Chen’s proceedings included 20 people; a larger study could thief corroborate nan results. Now, his squad wants to puzzle retired really semaglutide affects nan joints. He has a fewer hints. Lab experiments propose nan supplier scales up power accumulation successful cartilage. That could springiness nan insubstantial much substance to heal, Chen says.
