Managing rheumatoid arthritis-associated osteoporosis requires an ongoing, multidisciplinary effort to stop bone loss, fractures and falls, in response to consultants.
“Osteoporosis is a major concern in RA and thought to influence 30% to 50% of the inhabitants,” Katherine Wysham, MD, assistant professor within the division of rheumatology on the College of Washington, advised Healio. “Greater charges are seen in those that are feminine and 50 years of age and older.”
Damaged bones comprise the best threat on this particular affected person cohort, in response to Wysham.
“Importantly, folks with RA have 1.5 to 2 occasions the danger for osteoporotic fracture,” she stated.
Early intervention by all gamers is vital to mitigating these dangers, in response to Rachel Pessah-Pollack, MD, FACE, medical professor of drugs at New York College College of Drugs and NYU Langone Well being, and a Healio Endocrine In the present day editorial board member.
“Sadly, by the point I see these sufferers, they’re to the purpose of getting already low bone mass,” she advised Healio. “The schooling that should actually happen is methods to stop these sufferers from shedding bone within the first place.”
Understanding the danger components is step one, Wysham stated.

“The chance components for osteoporosis within the common inhabitants embody age, menopausal standing, low calcium or vitamin D consumption, BMI, muscle mass and glucocorticoid publicity,” she advised Healio. “In RA, nonetheless, there are disease-specific threat components which have been recognized, together with RA illness exercise, deformities or erosions, and positivity for anti-citrullinated protein antibody (ACPA).”
Mixed efforts from rheumatology, orthopedics and endocrinology are vital to conserving tabs on all of those components.
‘Vital accomplice’
Based on Wysham, most rheumatologists, orthopedists and endocrinologists are conscious that this specialised affected person inhabitants requires multidisciplinary care.
“Past helping in acute fracture restore, I respect when orthopedists refer their post-fracture sufferers to their main care supplier or one other specialist particularly for osteoporosis therapy,” Wysham stated.
Nevertheless, even with a number of physicians conscious of the dangers, sufferers fall can nonetheless by the cracks.
“We all know that the osteoporosis therapy charges are low even after osteoporotic fracture,” Wysham stated. “Listening to from an orthopedist that future fractures could also be prevented with therapy is a vital message for a affected person to listen to.”
Endocrinologists, in the meantime, are necessary accomplice in managing osteoporosis in RA as they’re typically the primary line for treating advanced or extra extreme osteoporosis instances, she added.
“The sufferers with RA that wind up in my workplace are those that have low bone mass, have osteoporosis and should even have had fractures, which locations them at very excessive threat for future fractures,” Pessah-Pollack advised Healio. “I’m not actually seeing the RA sufferers current to me in a preventive method.”
Like Wysham, Pessah-Pollack stated that each one gamers have to take part in early prognosis and intervention.
“I nonetheless do a secondary workup,” she stated. “We all know they’ve rheumatoid arthritis, however they might additionally produce other points, together with celiac illness, hyperparathyroidism and/or vitamin D deficiency.”
A 24-hour urine calcium verify could also be helpful, in response to Pessah-Pollack.
“I typically diagnose idiopathic hypercalciuria,” she stated. “Typically, for those who deal with this situation of excessive urine calcium you’ll be able to stabilize and even enhance their bone density. This inhabitants wants a secondary analysis, along with figuring out they have already got a secondary explanation for bone loss.”
As soon as a affected person with RA has undergone a piece up, prevention of osteoporosis turns into an ongoing problem.
‘As cell as attainable’
Based on consultants, it might be helpful to consider osteoporosis prevention in RA the identical method one would for these within the common inhabitants, in response to consultants. Comparable methods that apply within the common inhabitants additionally apply in RA, together with sustaining a wholesome physique weight and loads of train, with a calcium- and protein-rich weight-reduction plan.
Particular prevention methods in RA, in response to Wysham, embody tight RA illness management — as outlined by low illness exercise or remission — along with a wholesome physique composition, sustaining muscle mass, stimulating bone high quality by weight bearing train, and guaranteeing good steadiness to stop falls.
A weight-reduction plan wealthy in calcium, protein and vitamin D can be vital, she added.
“Resistance workout routines are important, as a result of we all know fracture prevention is vital,” Pessah-Pollack stated. “You need these sufferers to be as cell as attainable. With plenty of these continual ailments, mobility is considerably impaired, so something we are able to do to enhance mobility will assist their bone well being.”
The opposite key prevention issue is screening. Rheumatologists are inspired to familiarize themselves with osteoporosis screening tips for adults typically, together with these in danger for bone loss, which largely contains postmenopausal girls, in response to Pessah-Pollack.
“Based on the U.S. Preventative Companies Job Power, all postmenopausal girls needs to be screened for osteoporosis at age 65 years with no threat components,” she stated. “It is very important think about that RA is a threat issue, so rheumatologists ought to think about screening them earlier, no matter age, based mostly on their threat components akin to long run steroid use or if they’ve had a fragility fracture.”
Rheumatologists could discover it troublesome to search out details about osteoporosis prevention of their regular literature, Wysham stated.
“Sadly, there are not any particular tips addressing osteoporosis screening and administration in RA,” she advised Healio. “As a substitute, you’ll be able to mix completely different tips, together with these from the Nationwide Osteoporosis Basis and the American Faculty of Rheumatology’s glucocorticoid-induced osteoporosis guideline, to grasp who to display screen and deal with.”
Certainly, regardless of how cell a affected person could also be, steroid use may doubtlessly upend all different wellness and dietary methods to stop osteoporosis in RA.
A warning for continual glucocorticoid use
Based on Pessah-Pollack, sufferers who show continual glucocorticoid use — which ACR tips outline as 2.5 mg of day by day prednisone equal or extra for 3 months at a time — are strongly really useful to endure an preliminary medical fracture threat evaluation.
“If they’re 40 years of age or older, and have excessive or very excessive fracture threat, they need to be thought-about for bone preventive therapy to stop bone loss,” she stated.
Publish-menopausal girls are of essentially the most vital concern. Nevertheless, pre-menopausal men and women with RA who’ve skilled extended glucocorticoid publicity could also be candidates for osteoporosis screening, as properly.
In the meantime, the selection of therapy for RA-associated osteoporosis is often based mostly on bone mineral density and threat stratification measured by way of, for instance, the Fracture Threat Evaluation Device (FRAX).
“In case your calculated threat is 20% of a significant fracture over 10 years, or 3% of a hip fracture, we suggest therapy,” Pessah-Pollack stated. “Within the FRAX calculator itself, you may have the flexibility to decide on rheumatoid arthritis, as a result of we all know that could be a threat issue.”
Remedies might be categorized based mostly on how they work to stop bone loss, in response to Pessah-Pollack.
“They are often anti-remodeling to stop bone breakdown, or osteoanabolic — ie, constructing bone,” she stated.
“Usually, we take into consideration bisphosphonates,” she added.
Moreover, contemplating bisphosphonate remedy for sufferers on long-term glucocorticoids could be acceptable, in response to Pessah-Pollack.
“However, for example, the oral drugs may cause vital reflux,” she stated. “Plenty of occasions on this inhabitants, you’ll be able to have sufferers who’ve coexisting GERD, so an oral bisphosphate will not be an choice for them and IV bisphosphonate remedy could be most popular.”
Alendronate (Fosamax, Merck Sharp & Dohme) and risedronate (Actonel, Allergan) are oral formulations of bisphosphonate, whereas zoledronate (Reclast, Novartis) is the IV formulation.
“Zoledronate is a yearly infusion and needs to be tailor-made to the person circumstances and fracture threat,” Pessah-Pollack stated.
Age and fracture historical past are two further components to weigh when contemplating bisphosphonate remedy or one other class of medicines, she added.
“If in case you have had a fragility fracture, you might be at very excessive threat for a future fracture,” Pessah-Pollack advised Healio. “In that kind of state of affairs, we think about osteoanabolic therapy, which is bone constructing therapy.”
Nevertheless, no matter whether or not the affected person has been handled with steroids or has moved onto one other class of medicines, collaboration is vital, in response to Pessah-Pollack.
“It’s important to work with a rheumatologist to collaborate on this and likewise to get an thought of what the trajectory is, and in the event that they should be on glucocorticoids, or if there may be one other agent that they are often on that doesn’t trigger bone loss,” she stated. “I work carefully with my rheumatology colleagues and discover many rheumatologists throughout the area of bone illness prefer to focus and deal with this situation.”
For Wysham, the insidious nature of osteoporosis makes cooperation and intervention so important.
“Much like hypertension, osteoporosis is a silent illness and infrequently acknowledged after a fracture happens,” she stated.
