OA management guidelines forgo treatment hierarchy or order but emphasize severity, patient risk factors
ATLANTA – New guidelines for management of osteoarthritis of the hand, knee, and hip from the American College of Rheumatology and the Arthritis Foundation lay out a wide range of treatment options without an algorithm or hierarchy, making strong recommendations for nondrug interventions and for tailoring plans to individual patient-level factors.
Since the ACR last released OA management guidelines in 2012, a number of recommendations have been added, changed, and removed, and the structure of the guidelines has also changed. For instance, the new OA guidelines include a broad list of management options, Sharon L. Kolasinski, MD, chair of the ACR guidelines panel and professor of clinical medicine in the division of rheumatology at the University of Pennsylvania, Philadelphia, said in a presentation at the annual meeting of the American College of Rheumatology.
“The new guideline emphasizes comprehensive management of patients with OA, rather than a stepwise algorithm in a linear manner,” she said.
There is also no hierarchy to the recommendations, apart from the strength of the recommendation. “For any individual patient, a single option may be chosen at a particular time point, perhaps with or without other options, and may be reused in the future. For a given intervention, there might be a period of time over which it’s useful, and then the option might be changed,” Dr. Kolasinski noted.
Dr. Kolasinski advised making treatment decisions based on a patient’s disease severity, whether the patient uses medical devices, and in consideration of patient risk factors. “A history of injuries, surgical history, access to care, personal beliefs and preferences should all be brought to bear on decision making for osteoarthritis management,” she said.
The guidelines also advise considering a patient’s overall well-being and factors related to a patient’s perception of pain and function, such as mood disorders, altered sleep, chronic pain, impaired coping measures, and stress level. “Comprehensive management requires a broad assessment of how pain and function are affecting the patient with OA as a whole and recognizing that multiple options are available. They might be used in combination or change over time,” Dr. Kolasinski said.
The new guidelines place a strong emphasis on educational, behavioral, psychosocial, mind-body, and physical approaches. There are strong recommendations for the use of exercise, including aerobic, strengthening, neuromuscular, and aquatic exercise. Weight loss also carries a strong recommendation for patients with hip and knee OA, with a focus on group-based exercise, education, fitness and exercise goals, and a multidisciplinary approach using self-efficacy and self-management programs. The panels made a strong recommendation for tai chi to improve hip and knee OA. There are also strong recommendations for orthoses; aids and assistive devices such as canes, first carpometacarpal (CMC) orthoses, and tibiofemoral knee braces. Other interventions, such as Kinesio tape for first CMC joint and knee OA, hand orthoses, and patellofemoral knee braces, carried a conditional recommendation. Other conditional recommendations made by the panel were for acupuncture, thermal interventions, and radiofrequency ablation for patients with knee OA. Balance training for hip and knee OA, yoga for knee OA, and cognitive-behavioral therapy all were conditionally recommended by the panel.
The panel strongly recommended against the use of transcutaneous nerve stimulation for hip and knee OA, Dr. Kolasinski noted. The panel also conditionally recommended against use of modified shoes and pulsed vibration therapy in knee OA; lateral or medial wedged insoles, massage, and manual therapy with exercise in hip or knee OA; and iontophoresis in first CMC OA.
Tuhina Neogi, MD, PhD, chief of rheumatology at Boston University and member of the core team that developed the guidelines, said in her presentation the panel chose not to use the term “nonpharmacologic” in the guidelines because it may give patients a false impression that they are not receiving a treatment. “We really need to change our language and change the way in which we approach these conversations with our patients so that they don’t feel that they are not getting a treatment when we’re giving these recommendations,” she said.
Recommendations for, against pharmacologic approaches
The ACR has changed conditional recommendations for topical NSAIDs for knee and hand OA, oral NSAIDs, and intra-articular steroids for knee and hip OA into strong recommendations for the 2019 guidelines, Dr. Kolasinski said. While the 2012 guidelines conditionally recommended against topical capsaicin for knee OA, the new guidelines conditionally recommend it.
Other pharmacologic conditional recommendations included topical NSAIDs, chondroitin sulfate, and intra-articular corticosteroid injections for hand OA, acetaminophen, and duloxetine for knee OA.
With the new recommendations come changes that some rheumatologists and health care providers may find controversial. “I think that the practicing rheumatologist may be surprised that we have a recommendation against the use of hyaluronic acid in the knee as a conditional recommendation,” Dr. Kolasinski said. “The assessment of the literature at this point really reveals that there is equivalence between intra-articular hyaluronic acid injection and intra-articular saline injection, and so it was the feeling of the panel that, really, this was worth changing the recommendation from the 2012 guideline.”
The panel made strong recommendations against use of the following pharmacologic interventions:
- Bisphosphonates.
- Glucosamine sulfate.
- Combination glucosamine sulfate-chondroitin sulfate products.
- Hydroxychloroquine.
- Methotrexate.
- Intra-articular hyaluronic acid injections in hip OA.
- Chondroitin sulfate, platelet-rich plasma injections, and stem cell injections in hip and knee OA.
- Tumor necrosis factor (TNF) inhibitors.
- Interleukin-1–receptor antagonists.
Additionally, the panel made a conditional recommendation against topical capsaicin on the hand, colchicine, fish oil, vitamin D, intra-articular hyaluronic acid injections in the first CMC, and intra-articular botulinum toxin and prolotherapy in hip and knee OA.
The panel did not recommend for or against use of yoga for hip and hand OA, topical lidocaine, pregabalin, gabapentin, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors apart from duloxetine, tricyclic antidepressants, and anti-nerve growth factor agents.
While the panel conditionally recommended against use of opioids, they made a conditional recommendation for use of tramadol opioids, and there was “a heated discussion about that distinction,” Dr. Neogi noted in a discussion session at the meeting. “There was a recent observational study that indicated that tramadol may have an increased risk of [all-cause] mortality, but there are lots of issues of confounding by indication in that study.”
The patient panel also raised strong concerns about the ACR and the Arthritis Foundation coming out against opioids for OA management in their guidelines. “They don’t want to damn opioids, but they’re also concerned about a specialty society coming out strongly against opioids in the concern that their physicians may limit their access to opioids if they’re in a situation where nothing else is helping them,” Dr. Neogi said.
Dr. Kolasinski noted the guidelines will be published online in Arthritis & Rheumatology in December, and will appear in print in February of next year.
Dr. Kolasinski reported no relevant financial disclosures. Dr. Neogi reported relationships with EMD Serono, Merck, and Pfizer.

REPORTING FROM ACR 2019
Methotrexate may affect joint erosions but not pain in patients with erosive hand OA
ATLANTA – , according to results from the small, prospective, double-blind, randomized, placebo-controlled ADEM trial.
“Our study failed to show the superiority of methotrexate over placebo on pain evolution, but our results on structural evolution and the presence of inflammatory parameters as predictors of erosive evolution in nonerosive diseases may lead us to discuss the place of methotrexate in early steps of the disease evolution, and underlines the importance of the part played by the interaction between synovitis and subchondral bone in erosive progression,” Christian Roux, MD, PhD, of the department of rheumatology at Côte d’Azur University, Nice, France, said in his presentation at the annual meeting of the American College of Rheumatology.
Dr. Roux and colleagues enrolled 64 patients in the ADEM trial, where patients with symptomatic erosive hand osteoarthritis (EHOA) were randomized to receive 10 mg of methotrexate (MTX) per week or placebo. At 3 months, researchers assessed patients for pain using the Visual Analog Scale (VAS) score for hand pain, and secondary outcome measures at 12 months included VAS score for hand pain, radiographic progression using Verbruggen-Veys Anatomical Phase Score and Gent University Scoring System, and MRI.
Patients were included in the study if they were between 45 and 85 years old with a VAS pain score greater than 40, had failed classic therapeutics (acetaminophen, topical NSAIDs, and symptomatic slow-acting drugs), and had at least one erosive lesion. At baseline, the MTX and placebo groups were not significantly different with regard to gender (91% vs. 97% female), mean body mass index (24.6 kg/m2 vs. 24.2 kg/m2) and mean age (67.5 years vs. 64.9 years). Radiologic data showed joint loss, erosive, and erosive plus remodeling measurements were also similar between groups at baseline.
The mean VAS score for patients in the MTX group decreased from 65.7 at baseline to 48.2 at 3 months (–17.5; P = .07), compared with a decrease from 63.9 to 55.5 (–8.4; P = .002). At 12 months, VAS scores for patients in the MTX group decreased to 47.5, compared with a decrease in the placebo group to 48.2. However, the between-group differences for VAS scores were not significant at 3 months (P = .2) and at 12 months (P = .6).
“We have different hypotheses on the failure of our study on our main outcome, which was pain,” he said. “The first is a low-dose of methotrexate, and the second may be ... a placebo effect, which is very, very important in osteoarthritis.”
Dr. Roux noted the results from the ADEM trial were similar to a recent study in which 90 patients with hand OA were randomized to receive etanercept or placebo. At 24 weeks, there was no statistically significant difference between VAS pain in the etanercept group (between group difference, −5.7; 95% confidence interval, −15.9 to 4.5; P = .27) and the placebo groups, and at 1 year (between-group difference, –8.5; 95% CI, −18.6 to 1.6; P = .10), although the results favored patients receiving anti-tumor necrosis factor therapy (Ann Rheum Dis. 2018;77:1757-64. doi: 10.1136/annrheumdis-2018-213202).
With regard to the Verbruggen-Veys score, joint degradation was not significantly higher in the placebo group (29.4%), compared with the MTX group (7.7%), but there was a significantly higher number of erosive joints progressing to a remodeling phase in the MTX group (27.2%), compared with the placebo group (15.2%) at 12 months.
Dr. Roux said two factors are likely predictors of erosive disease based on data in ADEM: the level of interleukin-6 at baseline (odds ratio, 1.04; 95% CI, 1.03-1.06; P less than .0001), and joints with synovitis at baseline (OR, 4.7; 95% CI, 1.25-17.90; P = .02).
“Our study has several limitations, but we like to see our study as a pilot study,” he added, noting that a study analyzing bone turnover in patients with different doses of methotrexate and a longer disease duration is needed.
The authors reported no conflicts of interest.

Dr. Roux said two factors are likely predictors of erosive disease based on data in ADEM: the level of interleukin-6 at baseline (odds ratio, 1.04; 95% CI, 1.03-1.06; P less than .0001), and joints with synovitis at baseline (OR, 4.7; 95% CI, 1.25-17.90; P = .02).
“Our study has several limitations, but we like to see our study as a pilot study,” he added, noting that a study analyzing bone turnover in patients with different doses of methotrexate and a longer disease duration is needed.
The authors reported no conflicts of interest.

REPORTING FROM ACR 2019
Cannabinoids, stem cells lack evidence for osteoarthritis, expert says
LAS VEGAS – Planned clinical trials may clarify whether they benefit patients, said Joel A. Block, MD, professor of rheumatology at Rush University in Chicago.
Cannabinoid therapy “is on everybody’s mind, including our patients,” Dr. Block said at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education. “Cannabinoid receptors are widely present in all joint tissues, and endocannabinoids are clearly present in OA joint tissue. There is good evidence that the receptors regulate pain responses and central sensitization in a variety of OA animal models.” Where cannabis is legal, many people use it for chronic noncancer pain. Side effects may include altered perception, dizziness, drowsiness, and gastrointestinal adverse events.
Cannabis in the literature
“Nonetheless, if you do a systematic review of all of the randomized clinical trials of cannabinoids in human rheumatic diseases, what you will find is there is a grand total of four,” he said. The trials included patients with rheumatoid arthritis, OA, and fibromyalgia. An analysis of aggregated data found that cannabinoids improved pain and sleep, but all of the trials had a high risk of bias, poor allocation concealment, and poor blinding, said Dr. Block (Arthritis Care Res [Hoboken]. 2016 May;68[5]:681-8.). “In OA, there is one randomized trial, and it was entirely null,” he said. “There was no positive effect on pain or on function in human OA” (Pain. 2012 Sep;153[9]:1837-46.).
ClinicalTrials.gov lists two planned randomized controlled trials of cannabinoids – one using vaporized cannabis in patients with knee OA, and one using cannabidiol for hand OA and psoriatic arthritis. “Clinical trials are still scarce as of right now, so it will take a while before we have evidence for or against,” said Dr. Block.
Stem cell injections
Intra-articular stem cell injections are widely offered in the United States and abroad, he said. “In every newspaper, wherever I go, I open it up and there are full-page ads on stem cell injections that will cure everything that you want,” he said.
A systematic review of the effect of stem cell injections on structural outcomes and pain-related behaviors in animals found that “for all outcomes, the evidence quality was either low or very low,” Dr. Block said (Osteoarthritis Cartilage. 2018 Apr;26[4]:445-61.). “Even in the animal models, it has been very hard to demonstrate any effect at all from just injecting stem cells into the joint.”
Systematic reviews of the evidence in humans have found that the data do not support the use of stem cell injections. The authors of one review concluded, “In the absence of high-level evidence, we do not recommend stem cell therapy” for knee OA (Br J Sports Med. 2017 Aug;51[15]:1125-33.).
For another recent review, researchers screened hundreds of articles and identified 5 trials that met their inclusion criteria. They concluded, “Current evidence does not support the use of intra-articular [mesenchymal stem cells] for improving cartilage repair in knee osteoarthritis” (Arch Orthop Trauma Surg. 2019 Jul;139[7]:971-80.).
Many clinical trials are planned, however. “Over the next several years, I would expect that we are going to get some real data on whether these are helpful or not,” Dr. Block said.
Meanwhile, some patients spend thousands of dollars to receive stem cell injections, and clinics report average patient satisfaction rates of 82%. “How can they be getting so much relief when there is no evidence that it is helpful? In fact, whatever evidence we have says that it is no better than placebo,” said Dr. Block. “Placebo itself is very potent....People always do what they feel helps them regardless of objective data, because placebo itself is very palliative.”
Dr. Block is a consultant for GlaxoSmithKline, Medivir, and Zynerba Pharmaceuticals. He has received royalties from Agios, Daiichi Sankyo, and Omeros. In addition, he has received grant or research support from AbbVie, Janssen, Novartis, Pfizer, and Kolon TissueGene.

EXPERT ANALYSIS FROM PRD 2019
Consider centralized pain in patients with rheumatic disease
Las Vegas – A fibromyalgia survey may provide important information about the degree to which patients with rheumatic disease experience centralized pain. This information may guide treatment decisions, said Daniel J. Clauw, MD, professor of anesthesiology, rheumatology, and psychiatry and director of the Chronic Pain and Fatigue Research Center at the University of Michigan in Ann Arbor.
The questionnaire that Dr. Clauw uses is a patient self-report survey for the assessment of fibromyalgia based on criteria in the 2011 modification of the American College of Rheumatology preliminary diagnostic criteria for fibromyalgia. In it, he asks patients to report where they experience pain throughout the body and symptoms such as fatigue, sleep problems, and memory problems. The survey predicts outcomes of surgery for osteoarthritis better than x-rays, MRI scans, or psychological factors do, he said.
Physicians should ask every patient with chronic pain, including patients with OA, rheumatoid arthritis, or lupus, to complete the survey, Dr. Clauw said at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education. “This score will tell you the degree to which their central nervous system is augmenting or amplifying what is going on in their body,” he said. “And the higher their score is, the more you should treat them like you would someone with fibromyalgia, even if their underlying disease might be an autoimmune disease.”
Physicians should not use a cutoff of 13 points on the fibromyalgia measure to define whether a patient has the disease, as has been done in the past, he said. The threshold is arbitrary, he said. “We should not think about fibromyalgia as ‘yes’ or ‘no.’ We should think of the degree of fibromyalgia that people have.”
A poor relationship between pain and imaging
Some patients who have severe knee OA on imaging walk without pain. Other patients have normal x-rays, but severe pain. “There is a terrible relationship between what you see on a knee x-ray or an MRI and whether someone has pain,” Dr. Clauw said. Furthermore, the poor relationship between imaging and pain is common across chronic pain conditions, he said.
This phenomenon may occur because pain manifests in different ways, similar to there being multiple ways to adjust the volume of an electric guitar, he said. How hard the strings are strummed affects the volume. But so does the amplifier setting. “In these centralized pain conditions, the problem is an amplifier problem, not a guitar problem,” he said. “The amplifier, i.e., the central nervous system, is set too high.”
Researchers have found that people who have severe OA of the knee on x-ray but do not experience pain “have a very low amplifier setting,” he said. That is, they are nontender and less sensitive to pain. Most of these patients are men. “On average, men have a much lower amplifier setting than women,” he said. “This is also why ... women have 1.5 to 2 times the rate of any type of chronic pain than men, because on average women have a higher amplifier setting. ... In OA, at any given age, men and women have the exact same percentage of radiographic OA. But if you look at the clinical condition of OA, it is always two-thirds women, one-third men.”
Opioid responsiveness
To examine whether fibromyalgia survey results correlate with outcomes after knee and hip arthroplasty, Dr. Clauw and colleagues conducted a prospective, observational cohort study that included approximately 500 people. Patients completed the questionnaire on the day of surgery.
Patients with higher levels of fibromyalgia were less responsive to opioids. “For each 1-point increase in the fibromyalgia score, people needed about one more hydrocodone tablet in the first 24-48 hours to control their pain,” he said (Anesthesiology. 2013 Dec;119[6]:1434-43). In addition, each 1-point increase in the fibromyalgia score made people about 25% less likely to have a 50% improvement in knee pain level after 6 months (Arthritis Rheumatol. 2015 May;67[5]:1386-94). The correlations were independent of psychological factors. In addition, the associations were linear. “There was nothing magical about a fibromyalgia score of 13,” Dr. Clauw said.
Dr. Clauw is a coauthor of a study to be presented at the 2019 American College of Rheumatology/Association of Rheumatology Professionals annual meeting that found pain centralization in patients with RA is associated with poor response to disease-modifying antirheumatic drugs (DMARDs).
Prior studies in patients with RA have found that the degree of fibromyalgia is a better predictor of pain and disability than erythrocyte sedimentation rate or the number of swollen joints.
Diagnosed cases are the “tip of the iceberg”
Researchers at Dr. Clauw’s institution have identified dozens of patients undergoing knee surgery who met criteria for fibromyalgia but had not received the diagnosis. “This is at the University of Michigan, which is the epicenter for fibromyalgia research. If we are not seeing fibromyalgia superimposed on OA in our patients, no one is seeing it,” he said.
Patients with diagnosed fibromyalgia are “the tip of the iceberg,” he said. “There are far greater numbers of individuals whose primary diagnosis is OA, RA, lupus, ankylosing spondylitis, cancer pain, or sickle cell disease that have the same fundamental problem as fibromyalgia patients. But you do not see it because you label them as having an autoimmune disease or osteoarthritis. And that is at your peril and at their peril. Because treating that individual as if all of their pain and other symptoms are due to a problem out on the periphery will not make that person better.”
Patients with high levels of centralized pain may be less responsive to peripherally directed therapies such as surgery or injections, Dr. Clauw said. Pharmacologic options for patients with centralized pain include gabapentinoids (e.g., pregabalin and gabapentin), serotonin-norepinephrine reuptake inhibitors (e.g., duloxetine and milnacipran), and tricyclic compounds (e.g., amitriptyline and cyclobenzaprine), he said. “Opioids are going to be quite unlikely to help these individuals,” he said. “In fact, it is likely that opioids will make this kind of pain worse.”
Dr. Clauw is a consultant for Aptinyx, Daiichi Sankyo, Eli Lilly, Intec Pharma, Pfizer, Samumed, Theravance, Tonix, and Zynerba Pharma. He has received grant or research support from Aptinyx and Pfizer and is an expert witness.

EXPERT ANALYSIS FROM PRD 2019
Bariatric surgery has mostly positive impact in knee arthroplasty
a large study has found.
The study, led by Yicun Wang, PhD, of Nanjing (China) University was published in the Journal of Arthroplasty. “Generally speaking, bariatric surgery decreases some postoperative complications, decreases length of stay, and lowers mortality,” the study investigators wrote, [but] anemia and blood transfusion seem to be more common in patients with prior bariatric surgery.
They analyzed the effect of bariatric surgery on subsequent arthroplasty in morbidly obese patients in the United States using Nationwide Inpatient Sample 2006-2014 data on total hip arthroplasty (THA) and total knee arthroplasty (TKA). The researchers defined morbid obese patients as those with a body mass index higher than 40 kg/m2.
Among patients who underwent TKA, the researchers compared a group of 9,803 morbidly obese patients with the same number of patients who had undergone bariatric surgery. The two groups were matched by age, sex, income, primary insurance payer, and race.
There were large differences between the bariatric surgery group vs. morbidly obese group: Pulmonary embolism was much more common in the morbid obesity group (odds ratio, 0.22; 95% confidence interval, 0.05-1.03; P = .0346) while blood transfusion was more common in the bariatric surgery group (OR, 1.76; 95% CI, 1.52-2.03; P less than .0001).
For TKA, the researchers used the same approach to analyze 2,540 matched pairs of patients. In the bariatric surgery vs. morbidly obese comparison, pulmonary embolism was more common in the morbidly obese group (OR, 0.34; 95% CI, 0.20-0.57; P less than .0001), as were respiratory complications (OR, 0.45; 95% CI, 0.26-0.78; P = .0032) and death (OR, 0.07; 95% CI, 0.01-0.50; P = .0005). But the bariatric surgery group had higher levels of blood transfusion (OR, 1.87; 95% CI, 1.71-2.04; P less than .0001) and anemia (OR, 1.16; 95% CI, 1.09-1.24; P less than .0001).
Going forward, the researchers write, “future studies on these patients should attempt to evaluate the impact of bariatric surgery on the long-term outcomes of arthroplasty.”

Cannabidiol may interact with rheumatologic drugs
A number of medications commonly prescribed by rheumatologists may interact with cannabidiol oil, investigators at the Imperial College Healthcare NHS Trust, London, reported.
“Patients are increasingly requesting information concerning the safety of CBD oil,” Taryn Youngstein, MD, and associates said in letter to the editor in Rheumatology, but current guidelines on the use of medical cannabis do “not address the potential interactions between CBD oil and medicines frequently used in the rheumatology clinic.”
The most important potential CBD interaction, they suggested, may be with corticosteroids. Hydrocortisone and prednisolone both inhibit the cytochrome P450 enzyme CYP3A, but CBD is a potent inhibitor of CYP3A, so “concomitant use may decrease glucocorticoid clearance and increase risk of systemic [corticosteroid] side effects,” the investigators wrote.
CBD also is known to inhibit the cytochrome P450 isozymes CYP2C9, CYP2D6, CYP2C19, CYP3A4, and CYP1A2, which, alone or in combination, are involved in the metabolization of naproxen, tramadol, amitriptyline, and tofacitinib (Xeljanz), according to a literature search done via the college’s medicine information department that also used the British National Formulary and the Natural Medicines online interaction checker.
The Janus kinase inhibitor tofacitinib is included among the possible interactions, but the other Food and Drug Administration–approved JAK inhibitor, baricitinib (Olumiant), is primarily metabolized by the kidneys and should not have significant interaction with CBD, Dr. Youngstein and associates said. Most of the conventional synthetic and biologic disease-modifying antirheumatic drugs, including methotrexate, hydroxychloroquine, adalimumab (Humira), and abatacept (Orencia), also are expected to be relatively free from CBD interactions.
This first published report on interactions between CBD oil and common rheumatology medications “highlights the importance of taking comprehensive drug histories, by asking directly about drugs considered alternative medicines and food supplements,” they said.
The investigators declared no conflicts of interest, and there was no specific funding for the study.

Hemophilia carriers face elevated risk of joint comorbidities
Individuals who are carriers of hemophilia genes and have reduced clotting factor activity have at least a twofold higher risk of joint-related comorbidities, compared with the general population, according to new research.
In a population-based cohort study using patient registry data, Swedish researchers identified 539 potential carriers of impaired factor VIII or IX gene in the X chromosome – 213 of whom had documented factor activity – and paired them with sex‐ and birthdate‐matched controls from the general population.
They found that carriers with reduced factor activity had a 2.3-fold higher risk of a joint diagnosis, compared with the general population (95% confidence interval, 1.1-4.5). Carriers with normal factor activity did not show a statistically significant increase in joint diagnosis hazard, however carriers with unknown factor activity had a 2.4-fold higher risk of joint diagnosis, compared with controls (95% CI, 1.8-3.2). The findings were published in Haemophilia.
By the age of 60 years, around 37% of carriers with reduced or unknown factor activity had received a joint diagnosis, compared with 23% of carriers with normal factor activity.
The most common joint diagnoses across carriers and controls were knee related, including gonarthrosis and internal derangement, but these were more common among carriers. Five carriers also recorded a diagnosis of hemophilic arthropathy or systemic disorders of connective tissue in diseases classified elsewhere.
Researchers also saw a 10-fold higher risk of joint surgery (95% CI, 1.0-3.7) among carriers with reduced factor activity – although the numbers were small – and even among carriers with normal factor activity, there was a nearly twofold higher rate (95% CI, 0.9-4.6), compared with the control population.
Carriers with reduced or unknown factor activity also had a higher risk of outpatient hospitalization, compared with the general population, although no effect was seen in carriers with normal factor activity.
“Although the frequency of joint comorbidities overall was relatively low, our results clearly indicate and confirm a higher burden of joint afflictions, including an earlier age at joint diagnosis, for carriers with reduced or unknown factor activity compared with the general population, as well as more joint surgeries and related hospitalizations,” wrote Mehdi Osooli, PhD, from the Skåne University Hospital in Malmö, Sweden, and his coauthors.
The authors noted that the findings correlated with their earlier research on the incidence of arthropathy among males with mild hemophilia, who have previously been found to have a ninefold higher incidence of arthropathy‐related hospital admissions and a 16‐fold higher incidence of joint disease.
“The relatively higher incidence in the male population compared with the carriers in the current study may be explained by the lower median factor activity level, for example, levels between 5% and 40% in males with mild haemophilia compared with a median overall of 50% in carriers,” they wrote.
All authors declared that they had no conflict of interest related to the study findings. Four of the authors reported financial ties to companies including Novo Nordisk, Shire, and Bayer.

PROMIS tools provide useful data for managing rheumatology patients
LAKE BUENA VISTA, FLA. –
The PROMIS tools – which like most patient-reported outcome (PRO) measurement tools are designed to evaluate and monitor physical, mental, and social health – can be used both for the general population and for individuals living with chronic conditions, Dr. Curtis, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham (UAB), said at the annual meeting of the Florida Society of Rheumatology.
The tools take a deeper dive into various symptoms and their effects; for instance, with respect to physical health, they measure fatigue, physical function, sleep disturbance, pain intensity, and pain interference – the extent to which pain “messes your patient’s life up,” explained Dr. Curtis, who also is codirector of the UAB Pharmacoepidemiology and Pharmacoeconomics Unit.
Additional physical health domains that PROs measure include dyspnea, gastrointestinal symptoms, pain behavior, pain quality, sexual function, and sleep-related impairment.
These are “things that, honestly, we don’t talk about much as a field, but absolutely affect patients with autoimmune diseases,” he said. “You know, sexual function – that doesn’t come up in my practice spontaneously very often, but there are ways you can quantify that, and for many patients that’s actually a big deal.”
The domains measured by PROMIS tools for mental health look at anxiety and depression, but also delve into alcohol use, anger, cognitive function, life satisfaction, self-efficacy for managing chronic conditions, substance use, and more. The domains for social health address ability to participate in social roles and activities, as well as companionship, satisfaction with social roles and activity, social isolation, and social support.
“You can’t go on a hike with friends [and] be far from a bathroom, because you have bad arthritis and you have Crohn’s disease. Well, that’s kind of an important thing that may or may not come up in your discussions about inflammatory arthritis associated with [inflammatory bowel disease],” he said.
Another example is a patient who is embarrassed attending social functions or wearing a swimsuit because of really bad psoriasis.
“These are the kinds of things that I’m suggesting you and I probably want to measure if we’re providing holistic care to rheumatology patients,” Dr. Curtis said.
The PROMIS tools provide a simple, user-friendly means for doing so in English, Spanish, and many other languages, he noted.
All the scales use the same 1-100 scoring range, which simplifies measurements. They are available for free by download and can be printed or used electronically for use in the office, at home, on the web, and via smartphone.
The NIH developed the PROMIS tools several years ago and validated them for multiple chronic disease populations, Dr. Curtis said, adding that the tools include multiple individual domains and overall “profiles” of varying lengths.
Most are fixed-length scales that are between 4 and 10 questions and can be completed within 30-60 seconds per scale, so several scales can be completed within 5-10 minutes.
However, some scales are longer and provide greater detail.
“The nice thing is that if you ask a few more questions you can get more precise information – there’s more of a floor and ceiling. You can detect people who do really well. You can distinguish between the marathon runners and the 5K-ers and the people who can walk 2 miles but aren’t going to run a race,” he explained.
Further, the PROMIS tools, like the 36-item Short Form Health Survey (SF-36), are benchmarked against the U.S. adult population, allowing for assessment of how a specific drug or treatment “impacts your arthritis patient on a scale that would also be relevant for somebody who doesn’t have arthritis, they have diabetes.”
The metrics and scales are the same, and that can be helpful when trying to get a payer to pay for a particular drug, he said.
“None of these are rheumatology specific; this puts PROs into a language that can help rheumatology contend for the value of the care that we provide on a scale that would be relevant for any other chronic illness, even for nonrheumatology patients,” he explained.
In addition, minimally important differences (group mean change of about 2-3 units) and minimally clinical important differences for individuals (5 units) have been established.
“So we know what the numbers mean, and this is true for all of the scales,” he said.
PROMIS tools also include computer-adaptive testing (CAT) versions, which helps to personalize the scales to provide more precise information for a given patient and eliminate irrelevant information.
Of note, PROMIS health measures are among the data that can be tracked on a smartphone using Arthritis Power, an arthritis research registry developed with the help of a recent infrastructure grant awarded to the Center for Education and Research and Therapeutics of Musculoskeletal Disorders at UAB, Dr. Curtis said.
The measures were also shown in the AWARE study to track closely with other measures, including the Clinical Disease Activity Index (CDAI), and with patient improvement on therapy.
“So these PROMIS scores are tracking with things that you and I are familiar with ... and it looks like these scores are faithfully tracking, over time, patients getting better on therapies that we would expect them to,” he said. “I think this is additional validation – not just from the National Institutes of Health and a decade of research by lots of different groups, but in our own field – that these actually correlate with disease activity ... and that when you start an effective therapy like a [tumor necrosis factor inhibitor] they’re going to improve as you would anticipate.”
Dr. Curtis reported funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the Patient-Centered Outcomes Research Institute. He has also consulted for or received research grants from Amgen, AbbVie, Bristol-Myers Squibb, CORRONA, Lilly, Janssen, Myriad, Novartis, Roche, Pfizer, and Sanofi/Regeneron.

“So these PROMIS scores are tracking with things that you and I are familiar with ... and it looks like these scores are faithfully tracking, over time, patients getting better on therapies that we would expect them to,” he said. “I think this is additional validation – not just from the National Institutes of Health and a decade of research by lots of different groups, but in our own field – that these actually correlate with disease activity ... and that when you start an effective therapy like a [tumor necrosis factor inhibitor] they’re going to improve as you would anticipate.”
Dr. Curtis reported funding from the National Institute of Arthritis and Musculoskeletal and Skin Diseases and the Patient-Centered Outcomes Research Institute. He has also consulted for or received research grants from Amgen, AbbVie, Bristol-Myers Squibb, CORRONA, Lilly, Janssen, Myriad, Novartis, Roche, Pfizer, and Sanofi/Regeneron.
LAKE BUENA VISTA, FLA. –
The PROMIS tools – which like most patient-reported outcome (PRO) measurement tools are designed to evaluate and monitor physical, mental, and social health – can be used both for the general population and for individuals living with chronic conditions, Dr. Curtis, professor of medicine in the division of clinical immunology and rheumatology at the University of Alabama at Birmingham (UAB), said at the annual meeting of the Florida Society of Rheumatology.
The tools take a deeper dive into various symptoms and their effects; for instance, with respect to physical health, they measure fatigue, physical function, sleep disturbance, pain intensity, and pain interference – the extent to which pain “messes your patient’s life up,” explained Dr. Curtis, who also is codirector of the UAB Pharmacoepidemiology and Pharmacoeconomics Unit.
Additional physical health domains that PROs measure include dyspnea, gastrointestinal symptoms, pain behavior, pain quality, sexual function, and sleep-related impairment.
These are “things that, honestly, we don’t talk about much as a field, but absolutely affect patients with autoimmune diseases,” he said. “You know, sexual function – that doesn’t come up in my practice spontaneously very often, but there are ways you can quantify that, and for many patients that’s actually a big deal.”
The domains measured by PROMIS tools for mental health look at anxiety and depression, but also delve into alcohol use, anger, cognitive function, life satisfaction, self-efficacy for managing chronic conditions, substance use, and more. The domains for social health address ability to participate in social roles and activities, as well as companionship, satisfaction with social roles and activity, social isolation, and social support.
“You can’t go on a hike with friends [and] be far from a bathroom, because you have bad arthritis and you have Crohn’s disease. Well, that’s kind of an important thing that may or may not come up in your discussions about inflammatory arthritis associated with [inflammatory bowel disease],” he said.
Another example is a patient who is embarrassed attending social functions or wearing a swimsuit because of really bad psoriasis.
“These are the kinds of things that I’m suggesting you and I probably want to measure if we’re providing holistic care to rheumatology patients,” Dr. Curtis said.
The PROMIS tools provide a simple, user-friendly means for doing so in English, Spanish, and many other languages, he noted.
All the scales use the same 1-100 scoring range, which simplifies measurements. They are available for free by download and can be printed or used electronically for use in the office, at home, on the web, and via smartphone.
The NIH developed the PROMIS tools several years ago and validated them for multiple chronic disease populations, Dr. Curtis said, adding that the tools include multiple individual domains and overall “profiles” of varying lengths.
Most are fixed-length scales that are between 4 and 10 questions and can be completed within 30-60 seconds per scale, so several scales can be completed within 5-10 minutes.
However, some scales are longer and provide greater detail.
“The nice thing is that if you ask a few more questions you can get more precise information – there’s more of a floor and ceiling. You can detect people who do really well. You can distinguish between the marathon runners and the 5K-ers and the people who can walk 2 miles but aren’t going to run a race,” he explained.
Further, the PROMIS tools, like the 36-item Short Form Health Survey (SF-36), are benchmarked against the U.S. adult population, allowing for assessment of how a specific drug or treatment “impacts your arthritis patient on a scale that would also be relevant for somebody who doesn’t have arthritis, they have diabetes.”
The metrics and scales are the same, and that can be helpful when trying to get a payer to pay for a particular drug, he said.
“None of these are rheumatology specific; this puts PROs into a language that can help rheumatology contend for the value of the care that we provide on a scale that would be relevant for any other chronic illness, even for nonrheumatology patients,” he explained.
In addition, minimally important differences (group mean change of about 2-3 units) and minimally clinical important differences for individuals (5 units) have been established.
“So we know what the numbers mean, and this is true for all of the scales,” he said.
PROMIS tools also include computer-adaptive testing (CAT) versions, which helps to personalize the scales to provide more precise information for a given patient and eliminate irrelevant information.

EXPERT ANALYSIS FROM FSR 2019
NSAIDs a significant mediator of cardiovascular risk in osteoarthritis
Writing in Arthritis & Rheumatology, researchers reported the outcomes of a longitudinal, population-based cohort study of 7,743 individuals with osteoarthritis patients and 23,229 age- and sex-matched controls without osteoarthritis.
“The prevailing hypothesis in the OA to CVD relationship has been that OA patients frequently take NSAIDs to control their pain and inflammation and that this may lead to them developing CVD,” wrote Mohammad Atiquzzaman, a PhD student at the University of British Columbia, Vancouver, and his coauthors. However they commented that no studies had so far examined this directly in patients with osteoarthritis.
Overall, people with osteoarthritis had a significant 23% higher risk of cardiovascular disease, compared with controls, after adjustment for factors such body mass index, hypertension, diabetes, hyperlipidemia, and socioeconomic status. They also had a 42% higher risk of congestive heart failure, 17% higher risk of ischemic heart disease, and 14% higher risk of stroke.
NSAID use was five times more common among people with osteoarthritis, and NSAIDs alone were associated with a greater than fourfold higher risk of cardiovascular disease, after adjusting for osteoarthritis and other potential confounders.
When the authors performed modeling to break down the effect of osteoarthritis on CVD risk into the direct effect of osteoarthritis itself and the indirect effect mediated by NSAID use, they concluded that 41% of the total effect of osteoarthritis on cardiovascular risk was mediated by NSAIDs. The effect of NSAIDs was particularly pronounced for stroke, in which cases they estimated that the drugs contributed to 64% of the increased in risk, and in ischemic heart disease, in which they contributed to 56% of the increased risk.
Subgroup analysis suggested that conventional NSAIDs were responsible for around 29% of the total increased risk of cardiovascular disease, while selective COX-2 inhibitors, or coxibs, such as celecoxib, lumiracoxib, rofecoxib, and valdecoxib mediated around 21%. For ischemic heart disease, conventional NSAIDs explained around 45% of the increased risk, while selective coxibs explained around 32% of the risk. Similarly, with congestive heart failure and stroke, the proportion of risk mediated by NSAIDs was higher for conventional NSAIDs, compared with coxibs.
The authors noted that while a number of previous studies have found osteoarthritis is an independent risk factor for cardiovascular disease, theirs was the first study to specifically examine the role that NSAIDs play in that increased risk.
However, they noted that their information on NSAID use was gleaned from prescription claims data, which did not include information on over-the-counter NSAID use. Their analysis was also unable to include information on family history of cardiovascular disease, smoking, and physical activity, which are important cardiovascular disease risk factors. They did observe that the rates of obesity were higher among the osteoarthritis group when compared with controls (29% vs. 20%), and hypertension and COPD were also more common among individuals with osteoarthritis.
There was no outside funding for the study, and the authors had no conflicts of interest to declare.

Preoperative tramadol fails to improve function after knee surgery
according to findings of a study based on pre- and postsurgery data.
Tramadol has become a popular choice for nonoperative knee pain relief because of its low potential for abuse and favorable safety profile, but its impact on postoperative outcomes when given before knee surgery has not been well studied, wrote Adam Driesman, MD, of the New York University Langone Orthopedic Hospital and colleagues.
In a study published in the Journal of Arthroplasty, the researchers compared patient-reported outcomes (PRO) after total knee arthroplasty among 136 patients who received no opiates, 21 who received tramadol, and 42 who received other opiates. All patients who did not have preoperative and postoperative PRO scores were excluded
All patients received the same multimodal perioperative pain protocol, and all were placed on oxycodone postoperatively for maintenance and breakthrough pain as needed, with discharge prescriptions for acetaminophen/oxycodone combination (Percocet) for breakthrough pain.
Patients preoperative assessment using the Knee Disability and Osteoarthritis Outcome Score Jr. (KOOS, JR.) were similar among the groups prior to surgery; baseline scores for the groups receiving either tramadol, no opiates, or other opiates were 49.95, 50.4, and 48.0, respectively. Demographics also were not significantly different among the groups.
At 3 months, the average KOOS, JR., score for the tramadol group (62.4) was significantly lower, compared with the other-opiate group (67.1) and treatment-naive group (70.1). In addition, patients in the tramadol group had the least change in scores on KOOS, JR., with an average of 12.5 points, compared with 19.1-point and 20.1-point improvements, respectively, in the alternate-opiate group and opiate-naive group.
The data expand on previous findings that patients given preoperative opioids had proportionally less postoperative pain relief than those not on opioids, the researchers said, but noted that they were surprised by the worse outcomes in the tramadol group given its demonstrated side-effect profile.
The study findings were limited by several factors including the retrospective design and relatively short follow-up period, as well as the inability to accurately determine outpatient medication use, not only of opioids, but of nonopioid postoperative pain medications that could have affected the results, the researchers said.
“However, given the conflicting evidence presented in this study and despite the 2013 American Academy of Orthopedic Surgeons Clinical Practice Guidelines, it is recommended providers remain very conservative in their administration of outpatient narcotics including tramadol prior to surgery,” they concluded.
