Registry data reveal temporal relationship between psoriasis symptoms and PsA onset
ATLANTA – Psoriasis type and patient age at presentation among patients with psoriatic arthritis predict the timing of arthritis symptom synchronicity, according to findings from the Psoriatic Arthritis Registry of Turkey International Database.
However, in those who develop arthritis symptoms first, age at onset is not predictive of psoriatic arthritis (PsA) symptom synchronicity, Umut Kalyoncu, MD, reported at the annual meeting of the American College of Rheumatology.
Of 1,631 patients from the registry, 1,251 had psoriasis first, 71 had arthritis first, and 309 had synchronous onset, which was defined as the onset of both psoriasis and arthritis symptoms within a 12-month period. The time from skin disease to PsA was 155.6 months, –67.4 months, and 1.8 months, among the groups, respectively, and the mean age at PsA onset was similar, ranging from about 41 to 42 years in those who developed arthritis first, said Dr. Kalyoncu, of the department of rheumatology at Hacettepe University, Ankara, Turkey.
However, the mean age of PsA onset among those who developed psoriasis first was 29.4 years, compared with 46.3 years in those who developed arthritis first.
“So there is a really big difference between psoriasis beginning age,” he said.
PsA types also differed by onset symptoms: Axial involvement was more common with arthritis-first onset at 38.0%, compared with 28.8% for psoriasis first and 27.8% for synchronous onset). Oligoarthritis occurred more often with arthritis-first onset (45.1% vs. 30.7% and 29.4%, respectively), and polyarthritis occurred less often with arthritis-first onset (33.8% vs. 49.4% and 47.6%, respectively), he said.
Psoriasis type also differed among the groups: Pustular skin involvement was more common in arthritis-first patients (18.3% vs. 11.9% and 16.5% of psoriasis-first and synchronous-onset patients), scalp lesions as the initial lesion were more common in psoriasis-first patients (48.3% vs. 35.2% of arthritis-first patients and 39.8% of synchronous-onset patients), and genital involvement was present more often in arthritis-first patients (12.7% vs. 6.2% and 4.9% of psoriasis-first and synchronous-onset patients).
Early-onset (type 1) psoriasis was more common in psoriasis-first patients (74% vs. 28.1% and 51.8% of arthritis-first and synchronous-onset patients), whereas late-onset (type 2) psoriasis was more common in arthritis-first patients (71.9% vs. 26.0% and 48.2% for psoriasis-first and synchronous-onset patients).
A family history of psoriasis or PsA was more common in psoriasis-first patients (35.6% vs. 26.3% and 28.2% of arthritis-first and synchronous-onset patients), Dr. Kalyoncu said.
Treatment types did not differ between the groups.
Multiple linear regression analysis for the time elapsed from psoriasis to PsA symptom synchronicity, with all other independent variables set to baseline values, showed an overall intercept interval of 66 months, but with nail involvement, family history, or plaque psoriasis, the interval was extended by 28, 24, and 20 months, respectively. However, the presence of pustular psoriasis decreased the intercept interval by 28 months.
A temporal relationship between the onset of skin psoriasis and PsA is a well-known feature of psoriatic disease, with prior studies showing that the majority of cases involve psoriasis-first onset, Dr. Kalyoncu said, adding that heterogeneity in musculoskeletal and skin involvement is also a known feature.
However, little is known about the role of genetics, he noted.
Therefore, he and his colleagues used the Psoriatic Arthritis Registry of Turkey International Database, which was established in 2014 and now also includes data from patients in Canada and Italy, to explore the associations between disease characteristics and the temporal relationship of skin and musculoskeletal disease.
Based on the findings, age at the onset of psoriasis was the main factor that determined PsA symptom synchronicity, he said.
“We know that HLA-Cw6 is important in genetic susceptibility of psoriatic arthritis, but it is important only for early-onset arthritis, not late-onset psoriasis,” Dr. Kalyoncu said. “So our results make an indirect contribution [to the understanding of] these genetic and immunochemical differences between early-onset and late-onset psoriasis, and we need further future studies about this topic.”
Dr. Kalyoncu reported having no relevant disclosures.

Draft ACR Takayasu’s guidelines: Surgery is the last resort
ATLANTA – One of the goals in soon-to-be-published Takayasu’s arteritis guidelines from the American College of Rheumatology is to wean patients off high-dose steroids once they are in remission.
This recommendation is in opposition to another option – namely, switching these patients to low-dose glucocorticoids. The idea is to prevent long-term side effects, particularly in children. The guidelines also recommend against escalating immunotherapy for asymptomatic increases in inflammatory markers and generally recommend against surgery – stenting in most cases – unless there is threat to life, limb, or organ and also if limb pain is so severe it cramps quality of life and dose escalation doesn’t get the job done. If surgery is planned, patients should be on perioperative steroids if there’s active disease.
It’s draft guidance for now, but it’s probably what the final document will say when it’s published in 2020, according to a presentation at the annual meeting of the American College of Rheumatology by one of the authors, Anisha Dua, MD, an associate professor of rheumatology at Northwestern University, Chicago. She gave a sneak preview at the meeting.
In general, severe, active Takayasu’s calls for high-dose oral steroids in conjunction with a nonsteroid immunosuppressive, such as methotrexate, azathioprine, leflunomide, or mycophenolate mofetil. There’s evidence that dual therapy gives a more durable remission and also reduces the need for steroids.
When that approach doesn’t do the trick, the next step is a tumor necrosis factor (TNF) inhibitor. There’s evidence for infliximab, adalimumab, certolizumab, and etanercept. Dr. Dua noted, “We still can consider” tocilizumab, but it failed to meet its primary endpoint in a randomized trial, and evidence for other biologics is sparse or nonexistent. “TNF inhibitors are the first line” for refractory disease, Dr. Dua said.
The steroid taper comes after 6-12 months of remission. Given their toxicity, “our goal for steroids is zero,” especially in pediatric populations. Even in remission, patients should have a clinical assessment, including inflammatory markers, every 3-12 months.
A rise in C-reactive protein or erythrocyte sedimentation rate, with no new symptoms, might be a reason for more frequent monitoring, but it’s not a reason to escalate immunosuppression. That should be kept in reserve for new vascular lesions, rapid progression on an old one, or worsening of organ or limb ischemia.
“We recommend [escalation] over surgical intervention” because patients often develop collateral circulation that solves the problem; it also gives the disease time to quiet down should the patient eventually go into surgery. Immediate surgery is reserved for organ or life-threatening disease, Dr. Dua said.
“Takayasu’s is different from other vasculitides in the sense that patients often present with certain nonspecific constitutional symptoms,” and there’s not a lot of pathology or histology to work with, “so we do tend to rely on imaging a lot,” Dr. Dua said.
Angiography has fallen out of favor because it’s invasive and exposes patients to radiation, among other problems. The field has moved to noninvasive imaging such as color Doppler ultrasound, CT angiography, magnetic resonance angiography, and PET CT.
“We do recommend regularly scheduled, noninvasive imaging every 6-12 months, in addition to the routine clinical assessment,” except in children with inactive disease; the risk of sedation outweighs the imaging benefit, Dr. Dua said.
In patients with single-vessel cranial or cervical stenosis, without symptoms, “we recommend medical over surgical management because of the risk of surgery. Surgery can be considered for multivessel involvement,” she said.
She and her colleagues also recommend medical management for renal artery stenosis, including antihypertensives and immunotherapy escalation for active disease. Surgery is considered for refractory hypertension or worsening kidney function

Prednisolone scores for hand OA
ATLANTA – Dutch investigators at the annual meeting of the American College of Rheumatology made a good case for 6 weeks of low-dose prednisolone to help people with hand osteoarthritis get over a particularly bad spell.
A total of 42 patients randomized to prednisolone 10 mg/day fell a mean of 21.5 mm at 6 weeks from a baseline visual analog hand pain score of 54 mm (out of a possible 100 mm), versus a drop of 5.2 mm from a baseline score of 53 mm among 46 randomized to placebo; the mean group difference was 16.5 mm. Patients taking prednisolone did better on function, quality of life, and physician global assessments, too.
“This trial provides evidence that local inflammation is a suitable target for drug treatment in hand OA. We think this study provides clinicians with a short-term treatment option for patients who have a flare of their disease,” said lead investigator Féline Kroon, MD, a rheumatologist at Leiden (the Netherlands) University Medical Center.
“The large beneficial effect size exceeded that of all available therapeutic options for hand osteoarthritis,” including NSAIDs, she and her team noted in the study write-up, which was published to coincide with the meeting (Lancet. 2019 Nov 30;394[10213]:1993-2001).
Many physicians already use short-course prednisolone for hand OA, but there was no clinical evidence that it helped until now. The study also adds weight to the idea that OA has an inflammatory component – an idea that has been building for a while, Dr. Kroon said.
Leiden investigators and others have previously shown that synovial inflammation is often present in hand OA and a main determinant of pain and radiographic progression.
The 92 patients in the Low-Dose Prednisolone in Patients with Painful Hand Osteoarthritis (HOPE) trial had to have at least four interphalangeal joints (IPJs) with osteoarthritic nodes, at least one IPJ with soft swelling or erythema, and at least one with a positive power Doppler signal or grade 2 or higher synovitis on ultrasound. They also had to have flared at least 20 mm on the pain scale with NSAID washout.
There were more responders in the prednisolone group at 6 weeks (72% versus 33%), and significantly greater improvement in synovial thickening. There was no difference in power Doppler score or synovitis score per joint on MRI, but bone marrow lesions appeared less severe with prednisolone.
All the between-group differences disappeared when prednisolone was tapered after 6 weeks.
Four patients discontinued the study because of an adverse event: a myocardial infarction in the prednisolone group, and, in the control arm, a bowel surgery, an infected leg hematoma, and a case of Lyme arthritis of the knee. Adverse events were otherwise mild and similar in both arms.
The mean age in the study was 64 years, and 79% of the subjects were women. Exclusion criteria included chronic inflammatory rheumatic diseases, psoriasis, use of immune-modulating drugs within 90 days of baseline, and predominantly thumb base pain instead of finger pain.
The approach “is for short course. Long-term steroids can have important side effects, like osteoporosis. We do not think this study should be used to encourage prolonged prescribing of glucocorticoids in patients with hand OA,” Dr. Kroon said.
Two previous trials of glucocorticoids for hand OA were inconclusive. A dose of prednisone 5 mg/day for 4 weeks did not separate from placebo in one, and the second showed pain improvements with a combination of prednisolone and dipyridamole versus placebo, but with more adverse events, particularly dipyridamole headaches.
The work was funded by the Dutch Arthritis Society. Dr. Kroon did not have any disclosures.

“The large beneficial effect size exceeded that of all available therapeutic options for hand osteoarthritis,” including NSAIDs, she and her team noted in the study write-up, which was published to coincide with the meeting (Lancet. 2019 Nov 30;394[10213]:1993-2001).
Many physicians already use short-course prednisolone for hand OA, but there was no clinical evidence that it helped until now. The study also adds weight to the idea that OA has an inflammatory component – an idea that has been building for a while, Dr. Kroon said.
Leiden investigators and others have previously shown that synovial inflammation is often present in hand OA and a main determinant of pain and radiographic progression.
The 92 patients in the Low-Dose Prednisolone in Patients with Painful Hand Osteoarthritis (HOPE) trial had to have at least four interphalangeal joints (IPJs) with osteoarthritic nodes, at least one IPJ with soft swelling or erythema, and at least one with a positive power Doppler signal or grade 2 or higher synovitis on ultrasound. They also had to have flared at least 20 mm on the pain scale with NSAID washout.
There were more responders in the prednisolone group at 6 weeks (72% versus 33%), and significantly greater improvement in synovial thickening. There was no difference in power Doppler score or synovitis score per joint on MRI, but bone marrow lesions appeared less severe with prednisolone.
All the between-group differences disappeared when prednisolone was tapered after 6 weeks.
Four patients discontinued the study because of an adverse event: a myocardial infarction in the prednisolone group, and, in the control arm, a bowel surgery, an infected leg hematoma, and a case of Lyme arthritis of the knee. Adverse events were otherwise mild and similar in both arms.
The mean age in the study was 64 years, and 79% of the subjects were women. Exclusion criteria included chronic inflammatory rheumatic diseases, psoriasis, use of immune-modulating drugs within 90 days of baseline, and predominantly thumb base pain instead of finger pain.
The approach “is for short course. Long-term steroids can have important side effects, like osteoporosis. We do not think this study should be used to encourage prolonged prescribing of glucocorticoids in patients with hand OA,” Dr. Kroon said.
Two previous trials of glucocorticoids for hand OA were inconclusive. A dose of prednisone 5 mg/day for 4 weeks did not separate from placebo in one, and the second showed pain improvements with a combination of prednisolone and dipyridamole versus placebo, but with more adverse events, particularly dipyridamole headaches.
The work was funded by the Dutch Arthritis Society. Dr. Kroon did not have any disclosures.

Methotrexate gives durable remission from idiopathic granulomatous mastitis
ATLANTA – Methotrexate, in combination with prednisone, might be emerging as the go-to option for idiopathic granulomatous mastitis, according to investigators from Oregon Health & Science University, Portland.
Idiopathic granulomatous mastitis (IGM) is an inflammatory disease in which granulomas form in breast tissue. It strikes mostly young to middle-aged women with painful, firm breast masses, sometimes with redness and drainage. Diagnosis is by biopsy with rule-out of known causes.
IGM does not respond to antibiotics. Prednisone and surgery have been the traditional approaches, but masses can recur after surgery, and a year or more of prednisone, with the weight gain and side effects, is problematic. As a result, cases are increasingly being referred to rheumatologists for other options, said lead investigator Sarah Ringsted, MD, a rheumatology fellow at the university.
A study she presented at the annual meeting of the American College of Rheumatology and previous work from others builds a case for methotrexate, which often seems to put the disease in remission and allows for shorter glucocorticoid courses. These days, “I offer this to patients as a great option. It’s really nice to have, instead of having women go on months and months of high-dose steroids, and I think we can save patients from unnecessary” surgery, Dr. Ringsted said.
Her usual regimen these days is methotrexate 15-20 mg/week for 12-18 months, with high-dose prednisone (greater than 20 mg/day) for the first 3 months, followed by a taper.
Dr. Ringsted and associates compared 23 women treated at the university during 2007-2018. Just 5 of the 12 women (42%) treated with high-dose prednisone alone went into remission and did not relapse over a mean follow-up of 27 months. Two out of three women who had both high-dose glucocorticoids and surgery achieved remission without relapse, as did all three women who received methotrexate and high-dose glucocorticoids (one also had surgery). Five other patients were treated with other options; just two had a durable remission.
The numbers are small, but they add to two previous reports. Among 19 women who had failed other treatments, 94% improved and 75% went into remission with 15 months of methotrexate in a review from Stanford (Calif.) University. An Iranian study of 17 patients treated with methotrexate, and also glucocorticoids in some, had a relapse rate of only 17.8%.
There were several cases of both inflammatory arthritis and erythema nodosum in the Oregon series, a higher incidence than what has been reported before for IGM. “It’s interesting because it makes me think of sarcoidosis. There have been cases of sarcoidosis causing mastitis, but mostly in patients with other features” of the disease. “It makes me wonder if any of these women will develop sarcoidosis later on; I think that’s an interesting question,” Dr. Ringsted said.
Women in the study were an average age of 32 years, and over half were Hispanic, which is associated with a higher risk for IGM. Almost all the women had been pregnant before and had breast fed in the previous 5 years. Cancer, tuberculosis, and fungal infections were among the things ruled out before mastitis was deemed idiopathic.
Women with IGM tend to be of childbearing age, and must be cautioned against the teratogenic effects of methotrexate, Dr. Ringsted noted.
There was no external funding, and the investigators didn’t report any disclosures.

Down syndrome arthritis: Distinct from JIA and missed in the clinic
ATLANTA – Pediatric Down syndrome arthritis is more aggressive and severe than juvenile idiopathic arthritis (JIA), but it’s underrecognized and undertreated, according to reports at the annual meeting of the American College of Rheumatology.
“The vast majority of parents don’t know their kids are at risk for arthritis,” and a lot of doctors don’t realize it, either. Meanwhile, children show up in the clinic a year or more into the process with irreversible joint damage, said pediatric rheumatologist Jordan Jones, DO, an assistant professor at the University of Missouri, Kansas City, and the lead investigator on a review of 36 children with Down syndrome (DS) in the national Childhood Arthritis and Rheumatology Research Alliance (CARRA) registry.
One solution is to add routine musculoskeletal exams to American Academy of Pediatrics DS guidelines, something Dr. Jones said he and his colleagues are hoping to do.
Part of the problem is that children with DS have a hard time articulating and localizing pain, and it’s easy to attribute functional issues to DS itself. Charlene Foley, MD, PhD, from the National Centre for Paediatric Rheumatology in Dublin, said she’s seen “loads of cases” in which parents were told that their children were acting up, probably because of the DS, when they didn’t want to walk down stairs anymore or hold their parent’s hand.
She was the lead investigator on an Irish program that screened 503 DS children, about one-third of the country’s pediatric DS population, for arthritis; 33 cases were identified, including 18 new ones. Most of the children had polyarticular, rheumatoid factor–negative arthritis, and all of them were antinuclear antibody negative.
A key take-home from the work is that DS arthritis preferentially attacks the hands and wrists and was present exclusively in the hands and wrists of about one-third of the Irish cohort. “So, if you only have a second to examine a child or you can’t get them to sit still, just go straight for the hands, and have a low threshold for imaging,” Dr. Foley said.
DS arthritis is often considered a subtype of JIA, but findings from the studies call that into question and suggest the need for novel therapeutic targets, the investigators said.
The Irish team found that 42% of their subjects (14 of 33) had joint erosions, far more than the 14% of JIA children (3 of 21) who served as controls, and Dr. Foley and colleagues didn’t think that was solely because of delayed diagnosis. Also, at about 20 cases per 1,000, they estimated that arthritis was far more prevalent in DS than was JIA in the general pediatrics population.
Disease onset was at a mean of 7.1 years in Dr. Jones’ CARRA registry review, and mean delay to diagnosis was 11.5 months. The 36 children presented with an average of four affected joints. Only 22% (8 of 36) had elevated inflammatory markers; just one-third were positive for antinuclear antibody, and 17% for human leukocyte antigen B27. It means that “these kids can present with normal labs, even with very aggressive disease. The threshold of concern for arthritis has to be very high when you evaluate these children,” Dr. Jones said.
Treatment was initiated with disease-modifying antirheumatic drugs (DMARDs) in two-thirds of the registry children, often with a concomitant biologic, most commonly etanercept. Over half had at least one switch during a mean follow-up of 4.5 years; methotrexate was a leading culprit, frequently discontinued because of nausea and other problems, and biologics were changed for lack of effect. Active joint counts and physician assessments improved, but there were no significant changes in limited joint counts and health assessments.
In short, “the current therapies for JIA appear to be poorly tolerated, more toxic, and less effective in patients with Down syndrome. These kids don’t respond the same. They have a very high disease burden despite being treated aggressively,” Dr. Jones said.
That finding adds additional weight to the idea that DS arthritis is a distinct disease entity, with unique therapeutic targets. “Down syndrome has a lot of immunologic issues associated with it; maybe that’s it. I think in the next few years, we will be able to show that this is a different disease,” Dr. Jones said.
There was a boost in that direction from benchwork, also led and presented by Dr. Foley, that found significant immunologic, histologic, and genetic differences between JIA and DS arthritis, including lower CD19- and CD20-positive B-cell counts in DS arthritis and higher interferon-gamma and tumor necrosis factor–alpha production, greater synovial lining hyperplasia, and different minor allele frequencies.
There was no industry funding for the studies, and the investigators didn’t have any industry disclosures.

Be proactive in fracture prevention
Several studies published over the last few years have shown declining rates of diagnosis and treatment of osteoporosis in older adults. In part, this may be due to declining ability to diagnose osteoporosis because declining reimbursement for dual x-ray absorptiometry has made it less available to patients and doctors. The study by Curtis et al. from the annual meeting of the American College of Rheumatology confirms prior findings and confirmation is important in driving the message home.
More research is needed to understand the reasons why patients and health care providers are not diagnosing osteoporosis, given that we can easily do so, and not treating osteoporosis or accepting recommended treatments for osteoporosis, given that we have many effective treatments that reduce the risk of fractures, many of them very inexpensive.
The vast majority of Medicare patients have major risk factors for falls, and falls are the most important risk factor for osteoporotic fractures. It is important to be proactive, to ask about drugs and diseases than increase falls, to educate patients about how to prevent falls, and to initiate treatments that strengthen bones so that they are less likely to break as a consequence of falling.

Osteoporotic fracture risk is undermanaged in older adults
Treatment of osteoporosis in older adults at increased risk for fractures declined from 2010 to 2014, based on a study of nearly 900,000 individuals.
Osteoporotic fractures are associated with morbidity and mortality, functional decline, increased nursing home admissions, and a significant economic burden, Jeffrey R. Curtis, MD, of the University of Alabama at Birmingham, said in a presentation at the annual meeting of the American College of Rheumatology.
“The number of Americans at risk for fractures on the basis of having osteoporosis is expected to increase by 32% based on the graying of the population,” he said. “Underdiagnosis and undertreatment may be contributing to the increased burden that we are starting to see,” he added.
To assess the impact of osteoporosis management on patients at increased risk for fractures, Dr. Curtis and his colleagues examined temporal trends over 5 years from 885,676 Medicare fee-for-service members with a closed fragility (or osteoporosis-related) fracture between Jan. 1, 2010, and Dec. 31, 2014. The average age of the patients was 81 years; 91% were white, and 94% were women.
The researchers used diagnosis and procedure codes to create an algorithm with a positive predictive value of more than 90%. Individuals with Paget’s disease or a malignancy other than nonmelanoma skin cancer at baseline were excluded.
Overall, use of dual x-ray absorptiometry (DXA) screening in this high-risk population decreased over the study period, with rates during 2010-2014 of 25%, 24%, 23%, 22%, and 16%, respectively. The presence of an osteoporosis diagnosis in the study population decreased over the same period, with rates of 7%, 6%, 6%, 5%, and 4%, respectively. In addition, the percentage of high-risk patients undergoing osteoporosis treatment at the time of fracture during 2010-2014 was 29%, 24%, 20%, 16%, and 11%, respectively.
Despite their history of fracture, more than half of individuals in each year’s database had a comorbidity or were taking a medication that increased fall risk. The most common comorbidity was impaired mobility (about 20% of each yearly cohort), followed by history of falls, history of stroke, impaired vision, muscle atrophy or weakness, and Parkinson’s disease. Approximately half of the patients in each year’s group were taking opioids, and approximately 20% were taking oral corticosteroids.
The findings were limited by several factors, including those common to studies involving administrative claims databases, such as a lack of complete medical and treatment history, lack of diagnostic validation for osteoporosis-related fractures, and lack of information on why use of DXA decreased over time, Dr. Curtis said. However, the results show the need to improve management of individuals at increased risk for falls and fractures to reduce not only the risk of morbidity and mortality, but also the economic impact.

Treatment of osteoporosis in older adults at increased risk for fractures declined from 2010 to 2014, based on a study of nearly 900,000 individuals.
Osteoporotic fractures are associated with morbidity and mortality, functional decline, increased nursing home admissions, and a significant economic burden, Jeffrey R. Curtis, MD, of the University of Alabama at Birmingham, said in a presentation at the annual meeting of the American College of Rheumatology.
“The number of Americans at risk for fractures on the basis of having osteoporosis is expected to increase by 32% based on the graying of the population,” he said. “Underdiagnosis and undertreatment may be contributing to the increased burden that we are starting to see,” he added.
To assess the impact of osteoporosis management on patients at increased risk for fractures, Dr. Curtis and his colleagues examined temporal trends over 5 years from 885,676 Medicare fee-for-service members with a closed fragility (or osteoporosis-related) fracture between Jan. 1, 2010, and Dec. 31, 2014. The average age of the patients was 81 years; 91% were white, and 94% were women.

REPORTING FROM ACR 2019
Well-tolerated topical capsaicin formulation reduces knee OA pain
ATLANTA – Use of high-concentration topical capsaicin was associated with reduced pain, a longer duration of clinical response, and was well tolerated in patients with knee osteoarthritis, compared with lower concentrations of capsaicin and placebo, according to recent research presented at the annual meeting of the American College of Rheumatology.
While the ACR has recommended topical capsaicin for the relief of hand and knee OA pain, there are issues with using low-dose capsaicin, including the need for multiple applications and burning, stinging sensations at applications sites. As repeat exposure to capsaicin results in depletion of pain neurotransmitters and a reduction in nerve fibers in a dose-dependent fashion, higher doses of topical capsaicin are a potential topical treatment for OA pain relief, but their tolerability is low, Tim Warneke, vice president of clinical operations at Vizuri Health Sciences in Columbia, Md., said in his presentation.
“[P]oor tolerability has limited the ability to maximize the analgesic effect of capsaicin,” Mr. Warneke said. “While [over-the-counter] preparations of capsaicin provide some pain relief, poor tolerability with higher doses has really left us wondering if we haven’t maximized capsaicin’s ability to provide pain relief.”
Mr. Warneke and colleagues conducted a phase 2, multicenter, double-blind, parallel-group, vehicle-controlled trial where 120 patients with knee OA were randomized in a 1:1:1 ratio to receive 5% capsaicin topical liquid (CGS-200-5), 1% capsaicin topical liquid (CGS-200-1), or vehicle (CGS-200-0) and then followed up to 90 days. “The CGS-200 vehicle was developed to mitigate the burning, stinging pain of capsaicin,” Mr. Warneke said. “It allows the 5% concentration to be well tolerated, which opens the door for increased efficacy, including durability of response.”
Inclusion criteria were radiographically confirmed knee OA using 1986 ACR classification criteria, a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score of 250 mm or greater, and more than 3 months of chronic knee pain. While patients were excluded for use of topical, oral, or injectable corticosteroids in the month prior to enrollment, they were allowed to continue using analgesics such as NSAIDs if they maintained their daily dose throughout the trial. Mr. Warneke noted the study population was typical of an OA population with a mostly female, mostly Caucasian cohort who had a median age of 60 years and a body mass index of 30 kg/m2. Patients had moderate to severe OA and were refractory to previous pain treatments.
The interventions consisted of a single 60-minute application of capsaicin or vehicle to both knees once per day for 4 consecutive days, and patients performed the applications in the clinic. The investigators compared change in WOMAC pain scores between the groups at 31 days, 60 days, and 90 days post dose.
The results at 31 days showed a 46.2% reduction in WOMAC pain scores from baseline for patients using CGS-200-5, compared with a 28.3% reduction in the vehicle group (P = .02). At 60 days, there was a 49.1% reduction in WOMAC pain scores in the CGS-200-5 group, compared with 21.5% in patients using vehicle (P = .0001), and a 42.8% reduction for patients in the CGS-200-5 group at 90 days, compared with 22.8% in the vehicle group (P = .01). The CGS-200-1 group did not reach the primary efficacy WOMAC pain endpoint, compared with vehicle.
A post hoc analysis showed that there was a significantly greater mean reduction in WOMAC total score for patients using CGS-200-5, compared with vehicle at 31 days (P = .02), 60 days (P = .0005), and 90 days post dose (P = .005). “This durability of clinical response for single applications seems to be a promising feature of CGS-200-5,” Mr. Warneke said.
Concerning safety and tolerability, there were no serious adverse events, and one patient discontinued treatment in the CGS-200-5 group. When assessing tolerability at predose, 15-minute, 30-minute, 60-minute, and 90-minute postdose time intervals, the investigators found patients experienced mild or moderate adverse events such as erythema, edema, scaling, and pruritus, with symptoms decreasing by the fourth consecutive day of application.
Mr. Warneke acknowledged the “robust placebo response” in the trial and noted it is not unusual to see in pain studies. “It’s something that is a challenge for all of us who are in this space to overcome, but we still have significant differences here and they are statistically significant as well,” he said. “You have to be pretty good these days to beat the wonder drug placebo, it appears.”
Four authors in addition to Mr. Warneke reported being employees of Vizuri Health Sciences, the company developing CGS-200-5. One author reported being a former consultant for Vizuri. Three authors reported they were current or former employees of CT Clinical Trial & Consulting, a contract research organization employed by Vizuri to execute and manage the study, perform data analysis, and create reports.

REPORTING FROM ACR 2019
Hydroxychloroquine prevents congenital heart block recurrence in anti-Ro pregnancies
ATLANTA – Hydroxychloroquine (Plaquenil) 400 mg/day starting by pregnancy week 10 reduces recurrence of congenital heart block in infants born to women with anti-Ro antibodies, according to an open-label, prospective study presented at the annual meeting of the American College of Rheumatology.
Among antibody-positive women who had a previous pregnancy complicated by congenital heart block (CHB), the regimen reduced recurrence in a subsequent pregnancy from the expected historical rate of 18% to 7.4%, a more than 50% drop. “Given the potential benefit of hydroxychloroquine” (HCQ) and its relative safety during pregnancy, “testing all pregnancies for anti-Ro antibodies, regardless of maternal health, should be considered,” concluded investigators led by rheumatologist Peter Izmirly, MD, associate professor of medicine at New York (N.Y.) University.
About 40% of women with systemic lupus erythematosus and nearly 100% of women with Sjögren’s syndrome, as well as about 1% of women in the general population, have anti-Ro antibodies. They can be present in completely asymptomatic women, which is why the authors called for general screening. Indeed, half of the women in the trial had no or only mild, undifferentiated rheumatic symptoms. Often, “women who carry anti-Ro antibodies have no idea they have them” until they have a child with CHB and are tested, Dr. Izmirly said.
The antibodies cross the placenta and interfere with the normal development of the AV node; about 18% of infants die and most of the rest require lifelong pacing. The risk of CHB in antibody-positive women is about 2%, but once a child is born with the condition, the risk climbs to about 18% in subsequent pregnancies.
Years ago, Dr. Izmirly and his colleagues had a hunch that HCQ might help because it disrupts the toll-like receptor signaling involved in the disease process. A database review he led added weight to the idea, finding that among 257 anti-Ro positive pregnancies, the rate of CHB was 7.5% among the 40 women who happened to take HCQ, versus 21.2% among the 217 who did not. “We wanted to see if we could replicate that prospectively,” he said.
The Preventive Approach to Congenital Heart Block with Hydroxychloroquine (PATCH) trial enrolled 54 antibody positive women with a previous CHB pregnancy. They were started on 400 mg/day HCQ by gestation week 10.
There were four cases of second- or third-degree CHB among the women (7.4%, P = 0.02), all detected by fetal echocardiogram around week 20.
Nine of the women were treated with IVIG and/or dexamethasone for lupus flares or fetal heart issues other than advanced block, which confounded the results. To analyze the effect in a purely HCQ cohort, the team recruited an additional nine women not treated with any other medication during pregnancy, one of whose fetus developed third-degree heart block.
In total, 5 of 63 pregnancies (7.9%) resulted in advanced block. Among the 54 women exposed only to HCQ, the rate of second- or third-degree block was again 7.4% (4 of 54, P = .02). HCQ compliance, assessed by maternal blood levels above 200 ng/mL at least once, was 98%, and cord blood confirmed fetal exposure to HCQ.
Once detected, CHB was treated with dexamethasone or IVIG. One case progressed to cardiomyopathy, and the pregnancy was terminated. Another child required pacing after birth. Other children reverted to normal sinus rhythm but had intermittent second-degree block at age 2.
Overall, “the safety in this study was excellent,” said rheumatologist and senior investigator Jill Buyon, MD, director of the division of rheumatology at New York University.
The complications – nine births before 37 weeks, one infant small for gestational age – were not unexpected in a rheumatic population. “We were very nervous about Plaquenil cardiomyopathy” in the pregnancy that was terminated, but there was no evidence of it on histology.
The children will have ocular optical coherence tomography at age 5 to check for retinal toxicity; the 12 who have been tested so far show no obvious signs. Dr. Izmirly said he doesn’t expect to see any problems. “We are just being super cautious.”
The audience had questions about why the trial didn’t have a placebo arm. He explained that CHB is a rare event – one in 15,000 pregnancies – and it took 8 years just to adequately power the single-arm study; recruiting more than 100 additional women for a placebo-controlled trial wasn’t practical.
Also, “there was no way” women were going to be randomized to placebo when HCQ seemed so promising; 35% of the enrollees had already lost a child to CHB. “Everyone wanted the drug,” Dr. Izmirly said.
The majority of women were white, and about half met criteria for lupus and/or Sjögren’s. Anti-Ro levels remained above 1,000 EU throughout pregnancy. Women were excluded if they were taking high-dose prednisone or any dose of fluorinated corticosteroids at baseline.
The National Institutes of Health funded the work. The investigators had no relevant disclosures.

The audience had questions about why the trial didn’t have a placebo arm. He explained that CHB is a rare event – one in 15,000 pregnancies – and it took 8 years just to adequately power the single-arm study; recruiting more than 100 additional women for a placebo-controlled trial wasn’t practical.
Also, “there was no way” women were going to be randomized to placebo when HCQ seemed so promising; 35% of the enrollees had already lost a child to CHB. “Everyone wanted the drug,” Dr. Izmirly said.
The majority of women were white, and about half met criteria for lupus and/or Sjögren’s. Anti-Ro levels remained above 1,000 EU throughout pregnancy. Women were excluded if they were taking high-dose prednisone or any dose of fluorinated corticosteroids at baseline.

ATLANTA – Hydroxychloroquine (Plaquenil) 400 mg/day starting by pregnancy week 10 reduces recurrence of congenital heart block in infants born to women with anti-Ro antibodies, according to an open-label, prospective study presented at the annual meeting of the American College of Rheumatology.
Among antibody-positive women who had a previous pregnancy complicated by congenital heart block (CHB), the regimen reduced recurrence in a subsequent pregnancy from the expected historical rate of 18% to 7.4%, a more than 50% drop. “Given the potential benefit of hydroxychloroquine” (HCQ) and its relative safety during pregnancy, “testing all pregnancies for anti-Ro antibodies, regardless of maternal health, should be considered,” concluded investigators led by rheumatologist Peter Izmirly, MD, associate professor of medicine at New York (N.Y.) University.
About 40% of women with systemic lupus erythematosus and nearly 100% of women with Sjögren’s syndrome, as well as about 1% of women in the general population, have anti-Ro antibodies. They can be present in completely asymptomatic women, which is why the authors called for general screening. Indeed, half of the women in the trial had no or only mild, undifferentiated rheumatic symptoms. Often, “women who carry anti-Ro antibodies have no idea they have them” until they have a child with CHB and are tested, Dr. Izmirly said.
The antibodies cross the placenta and interfere with the normal development of the AV node; about 18% of infants die and most of the rest require lifelong pacing. The risk of CHB in antibody-positive women is about 2%, but once a child is born with the condition, the risk climbs to about 18% in subsequent pregnancies.
Years ago, Dr. Izmirly and his colleagues had a hunch that HCQ might help because it disrupts the toll-like receptor signaling involved in the disease process. A database review he led added weight to the idea, finding that among 257 anti-Ro positive pregnancies, the rate of CHB was 7.5% among the 40 women who happened to take HCQ, versus 21.2% among the 217 who did not. “We wanted to see if we could replicate that prospectively,” he said.
The Preventive Approach to Congenital Heart Block with Hydroxychloroquine (PATCH) trial enrolled 54 antibody positive women with a previous CHB pregnancy. They were started on 400 mg/day HCQ by gestation week 10.
There were four cases of second- or third-degree CHB among the women (7.4%, P = 0.02), all detected by fetal echocardiogram around week 20.
Nine of the women were treated with IVIG and/or dexamethasone for lupus flares or fetal heart issues other than advanced block, which confounded the results. To analyze the effect in a purely HCQ cohort, the team recruited an additional nine women not treated with any other medication during pregnancy, one of whose fetus developed third-degree heart block.
In total, 5 of 63 pregnancies (7.9%) resulted in advanced block. Among the 54 women exposed only to HCQ, the rate of second- or third-degree block was again 7.4% (4 of 54, P = .02). HCQ compliance, assessed by maternal blood levels above 200 ng/mL at least once, was 98%, and cord blood confirmed fetal exposure to HCQ.
Once detected, CHB was treated with dexamethasone or IVIG. One case progressed to cardiomyopathy, and the pregnancy was terminated. Another child required pacing after birth. Other children reverted to normal sinus rhythm but had intermittent second-degree block at age 2.
Overall, “the safety in this study was excellent,” said rheumatologist and senior investigator Jill Buyon, MD, director of the division of rheumatology at New York University.

VEDOSS study describes predictors of progression to systemic sclerosis
ATLANTA – , according to recent results from the Very Early Diagnosis Of Systemic Sclerosis (VEDOSS) study presented at the annual meeting of the American College of Rheumatology.
“Our data show that thanks [to a] combination of the signs that characterize the various phases of the disease, patients can be diagnosed [with systemic sclerosis] in the very early stages,” first author Silvia Bellando-Randone, MD, PhD, assistant professor in the division of rheumatology at the University of Florence (Italy), said in her presentation.
Dr. Bellando-Randone and colleagues performed a longitudinal, observational study of 742 patients (mean 45.7 years old) at 42 centers in a cohort of mostly women (90%), nearly all of whom had had Raynaud’s phenomenon for longer than 36 months (97.5%). Patients were excluded if they had systemic sclerosis based on ACR 1980 classification criteria and/or ACR–European League Against Rheumatism 2013 criteria, had systemic sclerosis together with other connective-tissue diseases, or were unlikely to be present for three consecutive annual exams. Data collection began in March 2012 with follow-up of 5 years.
The researchers determined the positive predictive values (PPV) and negative predictive values (NPV) of clinical features, systemic sclerosis–specific antibodies, and nailfold video capillaroscopy (NVC) abnormalities on progression from Raynaud’s phenomenon to systemic sclerosis. Laboratory data collected at baseline included presence of antinuclear antibodies (ANA), anticentromere antibodies (ACA), anti-DNA topoisomerase I antibodies (anti-Scl-70), anti-U1RNP antibodies, anti-RNA polymerase III antibodies (ARA), N-terminal pro b-type natriuretic peptides (NT-proBNP), and C-reactive protein/erythrocyte sedimentation rate. Dr. Bellando-Randone and colleagues also collected clinical, pulmonary function, lung high-resolution CT, echocardiographic, and ECG data at baseline.
Predictions were based on these factors alone and in combination. Overall, 65% of patients had positive ANA. Other baseline characteristics present in patients that predicted systemic sclerosis included positive ACA/anti-Scl-70/ARA (32%), NVC abnormalities such as giant capillaries (25%), and puffy fingers (17%).
Using Kaplan-Meier analysis, the researchers found 7.4% of 401 patients who were ANA positive progressed to meet ACR-EULAR 2013 criteria, and the percentage of these patients increased to 29.3% at 3 years and 44.1% at 5 years. When the researchers considered disease-specific antibodies alone, 10.6% of 90 patients progressed from Raynaud’s phenomenon to systemic sclerosis within 1 year, 39.6% within 3 years, and 50.3% within 5 years. When the researchers analyzed disease-specific antibodies and NVC abnormalities together, 16% of 72 patients progressed to systemic sclerosis within 1 year, 61.7% within 3 years, and 77.4% within 5 years.
Puffy fingers also were a predictor of progression, and 14.4% of 69 patients with puffy fingers alone progressed from Raynaud’s phenomenon to systemic sclerosis at 1 year, 47.7% at 3 years, and 67.9% at 5 years. Considering puffy fingers and disease-specific antibodies together, 20% of 27 patients progressed at 1 year, 56.3% at 3 years, and 91.3% at 5 years. No patients with puffy fingers together and NVC abnormalities progressed to systemic sclerosis at 1 year, but 60.4% of 22 patients progressed at 3 years before plateauing at 5 years. For patients with NVC abnormalities alone, 7.1% progressed to systemic sclerosis from Raynaud’s phenomenon at 1 year, 39.4% at 3 years, and 52.7% at 5 years.
“Regarding capillaroscopy, we have to say that not all centers that participated were equally screened in capillaroscopy, and so we cannot assume the accuracy of this data,” she said.
Dr. Bellando-Randone noted that, apart from puffy fingers, disease-specific antibodies, and NVC abnormalities, patients were more likely to have a history of esophageal symptoms if they progressed to systemic sclerosis (37.3%), compared with patients who did not progress (23.6%; P = .003).
Puffy fingers alone were an independent predictor of systemic sclerosis (PPV, 78.9%; NPV, 45.1%) as well as in combination with disease-specific antibodies (PPV, 94.1%; NPV, 43.9%). The combination of disease-specific antibodies plus NVC abnormalities also independently predicted progression to systemic sclerosis (PPV, 82.2%; NPV, 50.4%). In a Cox multivariate analysis, disease-specific antibodies (relative risk, 5.4; 95% confidence interval, 3.7-7.9) and puffy fingers (RR, 3.0; 95% CI, 2.0-4.4) together were strongly predictive of progression from Raynaud’s phenomenon to systemic sclerosis (RR, 4.3; 95% CI, 2.6-7.3).
“This is really important for the risk stratification of patients [in] the very early stages of the disease, even if these data should be corroborated by larger data in larger studies in the future,” said Dr. Bellando-Randone.
The investigators reported having no conflicts of interest.
