Taking anti-inflammatory symptom relievers similar ibuprofen and naproxen for osteoarthritis whitethorn worsen inflammation successful the genu associated implicit time, according to a caller survey being presented adjacent week astatine the annual meeting of the Radiological Society of North America (RSNA).
Osteoarthritis is the astir communal signifier of arthritis, affecting much than 32 cardinal adults successful the U.S. and much than 500 cardinal radical worldwide. It occurs astir often successful the hands, hips and knees. In radical with osteoarthritis, the cartilage that cushions the associated gradually wears away. Arthritis is often accompanied by inflammation, oregon swelling, of the joint, which tin beryllium painful.
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for osteoarthritis symptom and inflammation. But small is known of the semipermanent effects of these drugs connected illness progression.
“To date, nary curative therapy has been approved to cure oregon trim the progression of genu osteoarthritis,” said the study’s pb author, Johanna Luitjens, postdoctoral student successful the Department of Radiology and Biomedical Imaging astatine the University of California, San Francisco.
“NSAIDs are often utilized to dainty pain, but it is inactive an unfastened treatment of however NSAID usage influences outcomes for osteoarthritis patients. In particular, the interaction of NSAIDs connected synovitis, oregon the inflammation of the membrane lining the joint, has ne'er been analyzed utilizing MRI-based structural biomarkers.”
Dr. Luitjens and colleagues acceptable retired to analyse the relation betwixt NSAID usage and synovitis successful patients with osteoarthritis of the genu and to measure however attraction with NSAIDs affects associated operation implicit time.
“Synovitis mediates improvement and progression of osteoarthritis and whitethorn beryllium a therapeutic target,” Dr. Luitjens said. “Therefore, the extremity of our survey was to analyse whether NSAID attraction influences the improvement oregon progression of synovitis and to analyse whether cartilage imaging biomarkers, which bespeak changes successful osteoarthritis, are impacted by NSAID treatment.”
For the study, 277 participants from the Osteoarthritis Initiative cohort with mean to terrible osteoarthritis and sustained NSAID attraction for astatine slightest 1 twelvemonth betwixt baseline and four-year follow-up were included successful the survey and compared with a radical of 793 power participants who were not treated with NSAIDs. All participants underwent 3T MRI of the genu initially and aft 4 years. Images were scored for biomarkers of inflammation.
Cartilage thickness, creation and different MRI measurements served arsenic noninvasive biomarkers for evaluating arthritis progression.
The results showed nary semipermanent payment of NSAID use. Joint inflammation and cartilage prime were worse astatine baseline successful the participants taking NSAIDs, compared to the power group, and worsened astatine four-year follow-up.
“In this ample radical of participants, we were capable to amusement that determination were nary protective mechanisms from NSAIDs successful reducing inflammation oregon slowing down progression of osteoarthritis of the genu joint,” Dr. Luitjens said.
“The usage of NSAIDs for their anti-inflammatory relation has been often propagated successful patients with osteoarthritis successful caller years and should beryllium revisited, since a affirmative interaction connected associated inflammation could not beryllium demonstrated.”
According to Dr. Luitjens, determination are respective imaginable reasons wherefore NSAID usage increases synovitis.
“On the 1 hand, the anti-inflammatory effect that usually comes from NSAIDs whitethorn not efficaciously forestall synovitis, with progressive degenerative alteration resulting successful worsening of synovitis implicit time,” she said.
“On the different hand, patients who person synovitis and are taking pain-relieving medications whitethorn beryllium physically much progressive owed to symptom relief, which could perchance pb to worsening of synovitis, though we adjusted for carnal enactment successful our model.”
Dr. Luitjens noted that prospective, randomized studies should beryllium performed successful the aboriginal to supply conclusive grounds of the anti-inflammatory interaction of NSAIDs.
