Rheumatology

Researchers have found a link between age of diagnosis and various clinical characteristics and outcomes in patients with antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV).

The findings, presented at the annual meeting of the American College of Rheumatology, may have implications for research and treatment, especially in children.

AAV is a group of conditions characterized by the development of autoantibodies to the neutrophil proteins proteinase 3 (PR3-ANCA) or myeloperoxidase (MPO-ANCA).

The rare autoimmune condition can cause systemic inflammation and damage, sometimes permanent, to small- and medium-sized arteries. Clinical presentations vary and can include several organs, including skin, stomach, intestines, lung, and kidney, as well as airways in ear, nose, and throat.
 

Data limited on child vs. adult characteristics

AAV can be diagnosed in any decade of life, but clinical characteristics and outcomes often differ between children and adults, and data are limited. Studies often exclude children.

Lead author Jessica Bloom, MD, MSCS, a pediatric rheumatologist and assistant professor of pediatrics at Children’s Hospital Colorado, Aurora, and colleagues performed an analysis of patients with granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) who were enrolled in the Vasculitis Clinical Research Consortium Longitudinal Studies from 2013 to 2021.

Patients with eosinophilic GPA (EGPA) were analyzed separately. Children and young adults with EGPA were combined because of the small sample size (n = 87).

The groups were sorted by the age they were diagnosed: under 18 years old, 18-40, 40-65, and older than 65.
 

More than 1,000 patients included

Dr. Bloom’s team analyzed data from 1,020 patients: 61 diagnosed as children, 240 as young adults, 560 as middle-aged adults, and 159 diagnosed as older adults. At all ages, about nine out of 10 patients were White.

They found 852 (84%) had GPA and 165 (16%) had MPA. The analysis also showed 893 (92%) of patients with ANCA results were ANCA positive: 637 (65%) with PR3-ANCA, 247 (25%) with MPO-ANCA, and 9 (1%) with both.

Differences between age groups included:

• Children experienced more subglottic stenosis and alveolar hemorrhage than adults with the condition.
• About half of patients diagnosed in childhood received both cyclophosphamide and rituximab. That rate decreased with increasing age of diagnosis to as low as 14% for those diagnosed in older adulthood. 
• More females than males in all age groups were diagnosed with AAV, but the difference was most pronounced when diagnosed in childhood, and female predominance declined as age increased.
• Older adults experienced more neurologic disease and less musculoskeletal and sinus involvement.

Additionally, for those diagnosed after age 65, after adjusting for disease length and whether they were taking cyclophosphamide and/or rituximab, the Vasculitis Damage Index (VDI) and ANCA Vasculitis Index of Damage (AVID) scores were higher than for those diagnosed in childhood.

“However, these differences are no longer significant when medication toxicity and comorbidity-related items are excluded. Thus, differences in the VDI and AVID scores are driven by non–disease-specific damage,” Dr. Bloom said.
 

Bringing children into the clinical discussion

Dr. Bloom said in an interview that many pediatric rheumatologists believe kids with vasculitis are like small adults and should be treated similarly, but she said the picture may be more complex than that.

For example, the findings that children have more subglottic stenosis and alveolar hemorrhage than adults “may warrant more aggressive therapy,” she said. Children also have different growth and psychosocial risk factors during their disease course and may live longer with the disease than those in older age groups.

“Our study helps to point out these differences and bring children into the discussion,” Dr. Bloom said. “It also recognizes that damage scores used in studies and care may not adequately assess disease across the lifespan, as they are largely influenced by items not specific to the disease but rather medication toxicity and comorbidities, such as osteoporosis, cataracts, and malignancy.”

Robert Spiera, MD, director of the Scleroderma, Vasculitis, and Myositis Center at Hospital for Special Surgery, New York, said in an interview that the work highlights interesting information about the fact that disease features are skewed differently in children – “in particular the higher likelihood of upper airway [subglottic] disease, and potentially severe lower airway disease [alveolar hemorrhage].”

However, from a practical standpoint, Dr. Spiera said, “I am not sure that this will change our clinical approach to different patients, but the differences in disease features and even the sex differences in terms of who are afflicted with GPA [more often children and more likely to be female] may offer insights into disease pathogenesis.”

Dr. Bloom received funding from the Vasculitis Clinical Research Consortium and Vasculitis Foundation to conduct this work as a VCRC-VF fellow. Several coauthors reported various conflicts of interest with pharmaceutical companies. Dr. Spiera declared no relevant financial relationships.

AT ACR 2022

PHILADELPHIA – The first consensus screening guidelines for patients with idiopathic inflammatory myopathy (IIM) provide recommendations on risk stratification for individuals, basic and enhanced screening protocols, and screening frequency.

The recommendations, issued by the International Myositis Assessment and Clinical Studies Group (IMACS), stratify cancer risk for individual patients into low, intermediate, or high categories based on the IIM disease subtype, autoantibody status, and clinical features, reported Alexander Oldroyd, PhD, MSc, MBChB of the University of Manchester, England.

Neil Osterweil/MDedge News

“There’s a big unmet need for cancer screening. One in four adults with myositis has cancer, either 3 years before or after a diagnosis of myositis. It’s one of the leading causes of death in these patients, and they’re overwhelmingly diagnosed at a late stage, so we need standardized approaches to get early diagnosis,” he said in an interview at the annual meeting of the American College of Rheumatology.

Sharon Kolasinski, MD, of the University of Pennsylvania in Philadelphia, said in an interview that the guideline is a welcome development for rheumatologists. Dr. Kolasinski moderated the session where Dr. Oldroyd described the guideline, but she was not involved in its formulation.

“I think that we all have wondered for a very long time: What is the optimal cancer screening for myositis patients? We all worry that the onset of their diseases is associated with a coincident cancer, or that they will develop it soon,” she said.

Dr. Oldroyd emphasized that all patients with myositis have elevated risk for cancer compared with the general population and that the guideline categories of low, intermediate, and high are relative only to patients with IIM.
 

International consensus

The data on which the recommendations are based come from a systematic review and meta-analysis by Dr. Oldroyd and colleagues of 69 studies on cancer risk factors and 9 on IIM-specific cancer screening.

The authors of that paper found that the dermatomyositis subtype, older age, male sex, dysphagia, cutaneous ulceration and antitranscriptional intermediary factor-1 gamma (anti-TIF1-gamma) positivity were associated with significantly increased risk of cancer.

In contrast, polymyositis and clinically amyopathic dermatomyositis subtypes, Raynaud’s phenomenon, interstitial lung disease, very high serum creatine kinase or lactate dehydrogenase levels, and positivity for anti-Jo1 or anti-EJ antibodies were associated with significantly reduced risk of cancer.

The consensus recommendations were developed with anonymous contributions from 75 expert participants in 22 countries, with additional input from 3 patient partners.
 

Do this

The guideline lists 18 recommendations, of which 13 are strong and 5 are conditional.

An example of a strong recommendation is number 3, based on a moderate level of evidences:

“All adult IIM patients, irrespective of cancer risk, should continue to participate in country/region-specific age and sex appropriate cancer screening programs,” the guideline recommends.

Patients with verified inclusion body myositis or juvenile-onset IIM do not, however, require routine screening for myositis-associated cancer, the guideline says (recommendations 1 and 2).

There are also recommendations that all adults with new-onset IIM be tested for myositis-specific and myositis-associated autoantibodies to assist in stratifying patients by risk category.

The guideline divides screening recommendations into basic and enhanced. The basic screening should include a comprehensive history and physical exam, complete blood count, liver functions tests, erythrocyte sedimentation rates/plasma viscosity, serum protein electrophoresis, urinalysis, and chest x-ray.

Adults with IIM who are determined to be at low risk for IIM-related cancer should have basic cancer screening at the time of IIM diagnosis. Adults with intermediate risk should undergo both basic and enhanced screening at the time of IIM diagnosis, and those with high risk should undergo enhanced screening at the time of myositis diagnosis, with basic screening annually for 3 years, the recommendations say.
 

Consider doing this

Conditional recommendations (“clinicians should consider ...”) include the use of PET/CT for adults at high risk for cancer when an underlying cancer has not been detected at the time of IIM diagnosis. They also include a single screening test for anti-TIF1-gamma positive dermatomyositis patients whose disease onset was after age 40 and who have at least one additional risk factor.

Also conditionally recommended are upper and lower gastrointestinal endoscopy for patients at high risk when an underlying cancer is not found at the time of IIM diagnosis, nasoendoscopy in geographical regions with elevated risk for nasopharyngeal cancers, and screening for all IIM patients with red-flag symptoms or clinical features of cancer, including unexplained weight loss, family history of cancer, smoking, unexplained fever, or night sweats.
 

Guided steps

“I think clinicians have a lot of questions such as, ‘well, what should I do, when should I do it?’ These are important clinical questions, and we need guidance about this. We need to balance comprehensiveness with cost-effectiveness, and we need expert opinion about what steps we should take now and which should we take later,” Dr. Kolasinski said.

The guideline development process was supported by the University of Manchester, IMACS, National Institute for Health Research (United Kingdom), National Institutes of Health, National Health Service Northern Care Alliance, The Myositis Association, Myositis UK, University of Pittsburgh, Versus Arthritis, and the Center for Musculoskeletal Research. Dr. Oldroyd and Dr. Kolasinski reported having no relevant conflicts of interest.

Exercise tops the list of 28 recommendations in a guideline for integrative interventions in patients with rheumatoid arthritis developed by the American College of Rheumatology.

The guideline is specific to RA and presents integrative interventions to accompany treatment with disease-modifying antirheumatic drugs (DMARDs), according to a summary statement issued by the ACR. The summary was approved by the ACR Board of Directors on Oct. 31, and the recommendations are part of a manuscript that will be submitted for publication in both Arthritis & Rheumatology and Arthritis Care & Research.

Consistent engagement in exercise earned the only strong recommendation; the other 27 were conditional. In the exercise category, the authors offered conditional recommendations for aerobic exercise, aquatic exercise, resistance exercise, and mind-body exercise.

Three recommendations focused on diet. Notably, the recommended diet is Mediterranean style. Two other recommendations were specifically against any other formal diet and against the use of dietary supplements. “The conditional recommendation for adhering to a Mediterranean-style diet, but not other formally defined diets, to improve RA-specific outcomes may be surprising to some clinicians,” said Bryant R. England, MD, PhD, of the University of Nebraska Medical Center, Omaha, and one of the guideline’s coprincipal investigators, in a press release. “The voting panel acknowledged, however, that other health indications may exist for alternative diet and dietary supplements, which makes it crucial for clinicians and patients to engage in shared decision-making,” Dr. England said.

Nearly half of the 28 recommendations (13) focused on rehabilitation, but all were conditional. These included comprehensive occupational and physical therapy and hand therapy, as well as the use of splinting, orthoses, compression, bracing, and taping of affected areas. Other conditional recommendations supported the use of joint protection techniques, assistive devices, adaptive equipment, and/or environmental adaptations. The authors also included a conditional recommendation for vocational rehabilitation and work-site evaluations and/or modifications.

A category of additional integrative interventions included recommendations against both electrotherapy and chiropractic care. However, conditional recommendations were positive for acupuncture, massage therapy, and thermal modalities. Conditional recommendations also supported cognitive-behavioral therapy and/or mind-body strategies, and a standardized self-management program.

The guideline was developed by an interprofessional voting panel of 20 individuals with expertise in epidemiology, exercise physiology, GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology, integrative medicine, nursing, nutrition, occupational therapy, physical therapy, rheumatology, and social work, as well as three individuals who have RA. The panel developed questions, conducted a literature review, and used the GRADE approach to rate the certainty of evidence.

“These recommendations are specific to RA management, understanding that other medical indications and general health benefits may exist for many of these interventions,” the authors write in the summary statement.

The range of interventions shows both the importance of an interprofessional team–based approach to RA management and the need to engage patients in shared decision-making, they said.

Two other recommendations were specifically against any other formal diet and against the use of dietary supplements. “The conditional recommendation for adhering to a Mediterranean-style diet, but not other formally defined diets, to improve RA-specific outcomes may be surprising to some clinicians,” said Bryant R. England, MD, PhD, of the University of Nebraska Medical Center, Omaha, and one of the guideline’s coprincipal investigators, in a press release. “The voting panel acknowledged, however, that other health indications may exist for alternative diet and dietary supplements, which makes it crucial for clinicians and patients to engage in shared decision-making,” Dr. England said.

Nearly half of the 28 recommendations (13) focused on rehabilitation, but all were conditional. These included comprehensive occupational and physical therapy and hand therapy, as well as the use of splinting, orthoses, compression, bracing, and taping of affected areas. Other conditional recommendations supported the use of joint protection techniques, assistive devices, adaptive equipment, and/or environmental adaptations. The authors also included a conditional recommendation for vocational rehabilitation and work-site evaluations and/or modifications.

A category of additional integrative interventions included recommendations against both electrotherapy and chiropractic care. However, conditional recommendations were positive for acupuncture, massage therapy, and thermal modalities. Conditional recommendations also supported cognitive-behavioral therapy and/or mind-body strategies, and a standardized self-management program.

The guideline was developed by an interprofessional voting panel of 20 individuals with expertise in epidemiology, exercise physiology, GRADE (Grading of Recommendations Assessment, Development, and Evaluation) methodology, integrative medicine, nursing, nutrition, occupational therapy, physical therapy, rheumatology, and social work, as well as three individuals who have RA. The panel developed questions, conducted a literature review, and used the GRADE approach to rate the certainty of evidence.

“These recommendations are specific to RA management, understanding that other medical indications and general health benefits may exist for many of these interventions,” the authors write in the summary statement.

The range of interventions shows both the importance of an interprofessional team–based approach to RA management and the need to engage patients in shared decision-making, they said.

Exercise tops the list of 28 recommendations in a guideline for integrative interventions in patients with rheumatoid arthritis developed by the American College of Rheumatology.

The guideline is specific to RA and presents integrative interventions to accompany treatment with disease-modifying antirheumatic drugs (DMARDs), according to a summary statement issued by the ACR. The summary was approved by the ACR Board of Directors on Oct. 31, and the recommendations are part of a manuscript that will be submitted for publication in both Arthritis & Rheumatology and Arthritis Care & Research.

The incidence of dementia in patients with rheumatoid arthritis who took either a biologic disease-modifying antirheumatic drug (bDMARD) or targeted synthetic DMARD (tsDMARD) was significantly lower than the rate observed in patients who take only a conventional synthetic DMARD (csDMARD) in a national database study.

The work builds on previous research indicating a higher risk of Alzheimer’s disease and related dementias in people with RA. While joint pain and swelling are the cardinal symptoms of RA, its systemic inflammation leads to multiple systemic manifestations, offering biologically plausible links with cognitive decline. In addition, patients with RA have high prevalence of cardiovascular disease, diabetes, depression, disability, and physical inactivity, all of which are risk factors for dementia.

Chronic neuroinflammation secondary to either intrinsic or systemic stimuli is thought to play a key role in dementia development, especially Alzheimer’s dementia (AD). Research showing a role of tumor necrosis factor–alpha (TNF-alpha) in the development of dementia has piqued interest in a potential protective effect of TNF inhibitors. “TNF-alpha is thought to have an important role in different stages of the pathophysiology and disease progression of Alzheimer’s disease,” study first author Sebastian E. Sattui, MD, assistant professor of medicine at the University of Pittsburgh and director of the University of Pittsburgh Vasculitis Center, said in an interview. “Animal models have shown that TNF inhibition reduces microgliosis, neuronal loss, and tau phosphorylation. Cognitive improvement has been seen in two trials with Alzheimer’s disease patients, but were not in rheumatoid arthritis patients.”

In the newest study, published online in Seminars in Arthritis and Rheumatism, Dr. Sattui and colleagues suggest that a lower risk for dementia seen with bDMARDs and tsDMARDs may be attributable to an overall greater decrease in inflammation rather than any mechanism of action specific to these drugs.

In the study of Centers for Medicare & Medicaid Services claims during 2006-2017 for 141,326 adult patients with RA, the crude incident rates were 2.0 per 100 person-years (95% confidence interval, 1.9-2.1) for patients on csDMARDs and 1.3 (95% CI, 1.2-1.4) for patients on any b/tsDMARD. There were 3,794 cases of incident dementia during follow-up among 233,271 initiations of any DMARD. The adjusted risk for dementia among users of bDMARDs or tsDMARDs was 19% lower than the adjusted risk for patients on csDMARDs (hazard ratio, 0.81; 95% CI, 0.76-0.87). No significant differences were found between classes of bDMARDs or tsDMARDs.

Dr. Sattui and coauthors’ investigation included adults aged at least 40 years with two RA diagnoses by a rheumatologist more than 7 and less than 365 days apart. Those with prior dementia diagnoses were excluded. Their analysis found the risk of incident dementia to be comparable between patients receiving TNF inhibitors (HR, 0.86; 95% CI, 0.80-0.93), non-TNFi bDMARDs (HR, 0.76; 95% CI, 0.70-0.83), and tsDMARDs (HR, 0.69; 95% CI, 0.53-0.90), with csDMARDs as the referent. A second subgroup analysis looking at patients with prior methotrexate use who were taking bDMARDs or tsDMARDs revealed similar decreases in risk of incident dementia, compared with patients taking bDMARDs or tsDMARDs along with methotrexate at baseline.

“NSAIDs and glucocorticoids have been studied in RCTs [randomized, controlled trials],” Dr. Sattui said in the interview. “Despite initial observational data that showed some signal for improvement, no benefit was observed in either of the RCTs. Other agents with possible anti-inflammatory effects and more benign profiles, such as curcumin, are being studied. There are also ongoing trials looking into the use of JAK [Janus kinase] inhibitors or [interleukin]-1 inhibition in dementia.”

He added: “There is a need to better study the association between cognition and disease activity, as well as treat-to-target strategies, prospectively in patients with RA. It is important to also acknowledge that any of these findings might be just specific for RA, so extrapolation to non-RA individuals might be limited.”

In commenting on the findings of the study, Rishi J. Desai, PhD, assistant professor of medicine in the division of pharmacoepidemiology and pharmacoeconomics at Brigham and Women’s Hospital, Boston, said that “superior inflammation control with biologics or targeted DMARDs is an interesting hypothesis explaining the observed findings. It merits further investigation and replication in diverse populations.” He added: “It should be noted that a key challenge in evaluating this hypothesis using insurance claims data is unavailability of some important factors such as socioeconomic status and patient frailty. These may be driving treatment selection between conventional DMARDs, which are cheaper with more benign adverse-event profiles, and biologic or targeted DMARDs, which are more expensive with a less favorable adverse-event profile.”
 

Prior research

Several studies have investigated the effect of DMARDs, including bDMARDs like tumor necrosis factor inhibitors, on incident dementia in patients with RA.

Among this research is a study by Dr. Desai and colleagues that looked at comparative risk of AD and related dementia in 22,569 Medicare beneficiaries receiving tofacitinib (a JAK inhibitor), tocilizumab (an IL-6 inhibitor), or TNF inhibitors in comparison with abatacept (a T-cell activation inhibitor). No differentiating risk associations were found in this cohort study.

Other past studies include:

• A study comparing about 21,000 patients with RA and a non-RA cohort of about 62,000 found a 37% reduction in dementia development among RA patients receiving DMARDs. The effect was dose dependent, greater with high cumulative dosages, and was found in both men and women and in subgroups younger and older than 65 years.
• A retrospective study of electronic health records from 56 million adult patients identified a subset of patients with RA, psoriasis, ankylosing spondylitis, ulcerative colitis, or Crohn’s disease in whom systemic inflammation increased risk for AD through a mechanism involving TNF. The risk for AD in patients was lowered by treatment with etanercept, adalimumab, infliximab, or methotrexate, with larger reductions observed in younger patients than in older patients receiving TNF blockers.
• A propensity score–matched retrospective cohort study in 2,510 U.S. veterans with RA found that use of a TNF inhibitor reduced the risk of dementia by 36%, compared with control patients (HR, 0.64; 95% CI, 0.52-0.80), and the effect was consistent over 5-20 years post RA diagnosis.
• In a retrospective, multinational, matched, case-control study of patients older than 50 years with RA, prior methotrexate use was associated with lower dementia risk (OR, 0.71; 95% CI, 0.52-0.98). Use of methotrexate longer than 4 years demonstrated the lowest dementia risk (odds ratio, 0.37; 95% CI, 0.17-0.79).

These past studies, Dr. Sattui and colleagues pointed out, have multiple shortcomings, including case-control design, different definitions of exposure or outcomes, and inadequate control of confounders, underscoring the need for more rigorous studies.

Several authors of the CMS claims study disclosed research support, grants, and consulting fees from pharmaceutical companies. The research was supported by a grant from the National Institutes of Health. Dr. Desai disclosed that he has received funding from the National Institute on Aging for drug repurposing studies of dementia.

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.

Clinical composite scores (Disease Activity Score based on 28 joints with C-reactive protein) were reduced in patients with RA and PsA who were taking adalimumab and randomized to TDM, but no other clinical outcome differences were noted. Scores on the Health Assessment Questionnaire and global Visual Analog Scale for pain were significantly lower in patients in the TDM group who were taking infliximab and adalimumab, “indicating equally or superior sustained remission across diagnoses,” the researchers emphasized.

The findings were limited by several factors, including the variations in pathophysiology and open-label design. “However, since the TDM was based on an objective serum value and decision procedures were clear, we do not consider the potential of unconscious bias to outweigh the benefits of dose-changing abilities,” they wrote.

The researchers expressed surprise that the reduced use of TNF-alpha inhibitors did not significantly reduce adverse events or serious adverse events, compared with standard care, but they proposed that standard of care may have taken adverse events into account, because all patients had received prescriptions at least 3 months before the study.

As for clinical implications, the current costs of the biochemical assays necessary for TDM may be a barrier to implementing TDM as a standard part of daily clinical practice, the researchers added. However, the study was strengthened by the inclusion of patients with RA, PsA, and SpA, and is the first known to include patients receiving etanercept or adalimumab in an examination of TDM.

“Our data support TDM based solely on serum trough levels in [TNF-alpha inhibitors] with different pharmacokinetics as a future key player in personalized medicine for chronic rheumatoid diseases treated with biologics,” they concluded.

The study was supported by Spydspidspuljen, Region Midt, Denmark, and Department of Rheumatology, Aarhus University Hospital. The researchers had no financial conflicts to disclose.

The findings were limited by several factors, including the variations in pathophysiology and open-label design. “However, since the TDM was based on an objective serum value and decision procedures were clear, we do not consider the potential of unconscious bias to outweigh the benefits of dose-changing abilities,” they wrote.

The researchers expressed surprise that the reduced use of TNF-alpha inhibitors did not significantly reduce adverse events or serious adverse events, compared with standard care, but they proposed that standard of care may have taken adverse events into account, because all patients had received prescriptions at least 3 months before the study.

As for clinical implications, the current costs of the biochemical assays necessary for TDM may be a barrier to implementing TDM as a standard part of daily clinical practice, the researchers added. However, the study was strengthened by the inclusion of patients with RA, PsA, and SpA, and is the first known to include patients receiving etanercept or adalimumab in an examination of TDM.

“Our data support TDM based solely on serum trough levels in [TNF-alpha inhibitors] with different pharmacokinetics as a future key player in personalized medicine for chronic rheumatoid diseases treated with biologics,” they concluded.

The study was supported by Spydspidspuljen, Region Midt, Denmark, and Department of Rheumatology, Aarhus University Hospital. The researchers had no financial conflicts to disclose. 

Therapeutic drug monitoring allowed patients with rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis to reduce their dosage of tumor necrosis factor–alpha (TNF) inhibitors, based on data from 239 individuals.

Use of TNF-alpha inhibitors improves treatment response for many arthritis patients but dosage is rarely adjusted on an individual level, which may lead to unnecessary overdosing in some patients, Mogens Pfeiffer-Jensen, MD, of Aarhus (Denmark) University Hospital, and colleagues wrote.

Data from previous studies suggest that therapeutic drug monitoring (TDM) based on serum trough levels may allow for dose optimization and dose reduction in inflammatory bowel disease patients, but data in patients with arthritis are lacking, they wrote.

In a study published in the Scandinavian Journal of Rheumatology, the researchers recruited 99 patients with RA, 48 with psoriatic arthritis (PsA), and 92 with spondyloarthritis (SpA). The participants were randomized to standard care or standard care plus TDM. Serum trough levels were assessed at baseline and at every 4 months, and prescription changes or drug switches were implemented based on these levels. At baseline, 81 patients were being treated with infliximab (Remicade and biosimilars), 79 with etanercept (Enbrel), and 79 with adalimumab (Humira).

The primary endpoint was reduced drug prescription after 48 weeks.

Overall, TDM significantly reduced prescription of infliximab by 12% (P = .001) and prescription of etanercept by 15% (P = .01), compared with standard care. TDM also prolonged the interdosing intervals of etanercept by 235% (P = .02) and of adalimumab by 28% (P = .04), compared with standard care.

TDM patients taking infliximab had more frequent dose reduction and less frequent dose increases during and after the study when compared with patients who stayed with standard care; similar trends were seen with adalimumab. TDM also accelerated the switch to other biologics for patients on all three medications.

No significant differences occurred in adverse events or hospitalizations between the TDM and standard care patients.

Only about one in three patients seen in the emergency department of an academic health system for acute gout had a follow-up visit that addressed this condition, Lesley Jackson, MD, of the University of Alabama at Birmingham, reported at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network (G-CAN).

Dr. Jackson presented research done on patients seen within her university’s health system, looking at 72 patients seen in the ED between September 2021 and February 2022. Medications prescribed at discharge from the ED included corticosteroids (46 patients, or 64%), opioids (45 patients, 63%), NSAIDs (31 patients, 43%), and colchicine (23 patients, 32%).

Only 26 patients, or about 36%, had a subsequent outpatient visit in the UAB health system addressing gout, she said. Of 33 patients with any outpatient follow-up visit within the UAB system, 21 were within 1 month after the index ED visit, followed by 3 more prior to 3 months, and 9 more after 3 months.

The limitations of the study includes its collection of data from a single institution. But the results highlight the need for improved quality of care for gout, with too many people being treated for this condition primarily in the ED, she said.

In an email exchange arranged by the Arthritis Foundation, Herbert S. B. Baraf, MD, said he agreed that patients too often limit their treatment for gout to seeking care for acute attacks in the ED.

Because of competing demands, physicians working there are more to take a “Band-Aid” approach and not impress upon patients that gout is a lifelong condition that needs follow-up and monitoring, said Dr. Baraf, clinical professor of medicine at George Washington University, Washington, and an associate clinical professor at the University of Maryland, Baltimore. He retired from private practice in 2022.

“This problem is akin to the patient who has a hip fracture due to osteoporosis who gets a surgical repair but is never referred for osteoporotic management,” wrote Dr. Baraf, who is a former board member of the Arthritis Foundation.

He suggested viewing gout as a form of arthritis that has two components.

“The first, that which brings the patient to seek medical care, is the often exquisitely painful attack of pain and swelling in a joint or joints that comes on acutely,” he wrote. “Calming these attacks are the focus of the patient and the doctor, who does the evaluation as relief of pain and inflammation is the most pressing task at hand.”

But equally important is the second element, addressing the cause of these flare ups of arthritis, he wrote. Elevated uric acid leads to crystalline deposits of urate in the joints, particularly in the feet, ankles, knees, and hands. Over time, these deposits generate seemingly random flare ups of acute joint pain in one or more of these areas.

“Thus, when a patient presents to an emergency room with a first or second attack of gout, pain relief is the primary focus of the visit,” Dr. Baraf wrote. “But if over time that is the only focus, and the elevation of serum uric acid is not addressed, deposits will continue to mount and flare ups will occur with increasing frequency and severity.”

This study was supported by a grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Jackson has no relevant financial disclosures.

Knee and hip replacements can improve how well patients get around and can significantly increase their quality of life. But if a bone near the new joint breaks, the injury can be a major setback for the patient’s mobility, and the consequences can be life-threatening.

The proportion of patients who experience a periprosthetic fracture within 5 years of total hip arthroplasty is 0.9%. After total knee arthroplasty (TKA), the proportion is 0.6%, research shows.

Those rates might seem low. But given that more than a million of these joint replacement surgeries are performed each year in the United States – they are the most common inpatient surgical procedures among people aged 65 and older – thousands of revision surgeries due to periprosthetic fractures occur each year.

Primary care physicians, surgeons, and researchers are trying to identify risk factors, medication regimens, and nondrug approaches to avoid these complications. Primary care clinicians who make their patients’ bone health a priority early on – years before surgery, ideally – may help patients enjoy the benefits of new joints long term.

At the 2022 annual Santa Fe Bone Symposium this summer, Susan V. Bukata, MD, professor and chair of orthopedics at the University of California, San Diego, showed an image of “what we’re trying to avoid” – a patient with a broken bone and infection. Unfortunately, Dr. Bukata said, the patient’s clinicians had not adequately addressed her skeletal health before the injury.

“This is a complete disaster for this person who went in having a total hip to improve their function and now will probably never walk normally on that leg,” Dr. Bukata said at the meeting.

The patient eventually underwent total femur replacement. Five surgeries were required to clear the infection.

Medical and surgical advances have allowed more people – including older patients and those with other medical conditions – to undergo joint replacement surgery, including replacement of knees, hips, and shoulders.

The surgeries often are performed for adults whose bones are thinning. Sometimes surgeons don’t realize just how thin a patient’s bone is until they are operating.
 

Prioritizing bone health

In patients with osteoporosis, the bone surrounding the new joint is weaker than the metal of the prosthesis, and the metal can rip out of the bone, Dr. Bukata told this news organization. A periprosthetic fracture should be recognized as an osteoporotic fracture, too, although these fractures have not typically been categorized that way, she said.

People live with total joints in place for as long as 40 years, and fractures around the implants are “one of the fastest growing injuries that we are seeing in older patients,” Dr. Bukata said. “People don’t think of those as osteoporotic fractures. But a 90-year-old who falls and breaks next to their total knee, if they didn’t have that total knee in place, everybody would be, like, ‘Oh, that’s an osteoporotic fracture.’ ”

Periprosthetic fractures tend not to occur right after surgery but rather after the bone continues to lose density as the patient ages, Dr. Bukata said.
 

Missed chances

One approach to preventing periprosthetic fractures could involve prioritizing bone health earlier in life and diagnosing and treating osteoporosis well before a patient is scheduled for surgery.

A patient’s initial visit to their primary care doctor because of joint pain is an opportunity to check on and promote their bone health, given that they might be a candidate for surgery in the future, Dr. Bukata said.

Ahead of a scheduled surgery, patients can see endocrinologists or rheumatologists to receive medication to try to strengthen bones. Doctors may be limited in how much of a difference they can make in a matter of several weeks or months with these drugs, however. These patients still likely will need to be treated as if they have osteoporosis, Dr. Bukata said.

When surgeons realize that a patient has weaker bones while they are in the middle of an operation, they should emphasize the importance of bone health after the procedure, Dr. Bukata said.

Strengthening, maintaining, and protecting bone should be seen as a long-term investment in the patient’s success after a joint replacement. That said, “There is no clear evidence or protocol for us to follow,” she said. “The mantra at UCSD now is, let’s keep it simple. Get the patient on track. And then we can always refine things as we continue to treat the patient.”

Health systems should establish routines in which bone health is discussed before surgery in the way patient education programs address smoking cessation, nutrition, and weight management, Dr. Bukata said. Another step in the right direction could involve setting electronic medical records to automatically order assessments of bone health when a surgeon books a case.

Linda A. Russell, MD, rheumatologist and director of perioperative medicine at the Hospital for Special Surgery in New York, said periprosthetic fractures are a “complication we fear.”

“It’s a big deal to try to repair it,” Dr. Russell said. “Sometimes you need to revise the joint, or sometimes you need to put lots more hardware in.” Surgeons increasingly appreciate the need to pay attention to the quality of the bone before they operate, she said.

Nevertheless, Dr. Russell does not necessarily say that such cases call for alarm or particularly aggressive treatment regimens – just regular bone health evaluations before and after surgery to see whether patients have osteoporosis and are candidates for treatment.
 

Lifelong effort

In some ways, to address bone health at the time of surgery may be too late.

Bone health “is not something that you can have as an afterthought when you’re 75 years old,” said Elizabeth Matzkin, MD, chief of women’s sports medicine at Brigham and Women’s Hospital, in Boston.

The chance of being able to rebuild bone mass at that age is slim. If patients maximize bone density when they are young, they can afford to lose some bone mass each year as they age.

To that end, a healthy diet, exercise, not smoking, and cutting back on alcohol can help, she said.

For Dr. Matzkin, a fragility fracture is a red flag that the patient’s bone density is probably not optimal. In such cases, she prepares for various scenarios during surgery, such as a screw not holding in a low-density bone.

Recently published research reflects that prior fragility fractures are a significant risk factor for complications after surgery, including periprosthetic fractures.

Edward J. Testa, MD, of Brown University, Providence, R.I., and colleagues analyzed insurance claims to compare outcomes for 24,398 patients who had experienced a fragility fracture – that is, a break caused by low-velocity trauma such as a fall – during the 3 years before their TKA procedure and a matched group of patients who were similar in many respects but who had not had a fragility fracture in the 3 years before surgery.

Dr. Testa’s group found that a history of fragility fracture was associated with higher rates of complications in the year after surgery, including hospital readmissions (hazard ratio = 1.30; 95% CI, 1.22-1.38), periprosthetic fractures (odds ratio = 2.72; 95% CI, 1.89-3.99), and secondary fragility fractures (OR = 4.62; 95% CI, 4.19-5.12). Patients who had previously experienced fragility fractures also experienced dislocated prostheses (OR = 1.76; 95% CI, 1.22-2.56) and periprosthetic infections (OR = 1.49; 95% CI, 1.29-1.71) at higher rates.

The rates of complications were similar regardless of whether patients had filled a prescription for medications used to treat osteoporosis, including bisphosphonates, vitamin D replacement, raloxifene, and denosumab, the researchers reported.

The lack of a clear association between these treatments and patient outcomes could be related to an insufficient duration of pharmacotherapy before or after TKA, poor medication adherence, or small sample sizes, Dr. Testa said.

Given the findings, which were published online in the Journal of Arthroplasty, “patients with a history of fragility fracture should be identified and counseled appropriately for a possible increased risk of the aforementioned complications, and optimized when possible, prior to undergoing TKA,” Dr. Testa told this news organization. “Ultimately, the decision to move forward with surgery is far more complex than the identification of this sole, yet important, risk factor for certain postoperative, implant-related complications.”
 

Treatment gaps

Prior research has shown that women aged 70 years and older are at higher risk for periprosthetic fractures. Many women in this age group who could receive treatment for osteoporosis do not, and major treatment gaps exist worldwide, noted Neil Binkley, MD, with the University of Wisconsin–Madison, in a separate talk at the Santa Fe Bone Symposium.

Ensuring adequate protein intake and addressing the risk of falling are other measures that clinicians can take to promote healthy bones, apart from prescribing drugs, he said.

Unpublished data from one group show that nearly 90% of periprosthetic fractures may result from falls, while about 8% may be spontaneous. “We need to be thinking about falls,” Dr. Binkley said.

Dr. Bukata has consulted for Amgen, Radius, and Solarea Bio and has served on a speakers bureau for Radius. She also is a board member for the Orthopaedic Research Society and the American Academy of Orthopaedic Surgeons Board of Specialty Societies. Dr. Binkley has received research support from Radius and has consulted for Amgen.

“This is a complete disaster for this person who went in having a total hip to improve their function and now will probably never walk normally on that leg,” Dr. Bukata said at the meeting.

The patient eventually underwent total femur replacement. Five surgeries were required to clear the infection.

Medical and surgical advances have allowed more people – including older patients and those with other medical conditions – to undergo joint replacement surgery, including replacement of knees, hips, and shoulders.

The surgeries often are performed for adults whose bones are thinning. Sometimes surgeons don’t realize just how thin a patient’s bone is until they are operating.
 

Prioritizing bone health

In patients with osteoporosis, the bone surrounding the new joint is weaker than the metal of the prosthesis, and the metal can rip out of the bone, Dr. Bukata told this news organization. A periprosthetic fracture should be recognized as an osteoporotic fracture, too, although these fractures have not typically been categorized that way, she said.

People live with total joints in place for as long as 40 years, and fractures around the implants are “one of the fastest growing injuries that we are seeing in older patients,” Dr. Bukata said. “People don’t think of those as osteoporotic fractures. But a 90-year-old who falls and breaks next to their total knee, if they didn’t have that total knee in place, everybody would be, like, ‘Oh, that’s an osteoporotic fracture.’ ”

Periprosthetic fractures tend not to occur right after surgery but rather after the bone continues to lose density as the patient ages, Dr. Bukata said.
 

Missed chances

One approach to preventing periprosthetic fractures could involve prioritizing bone health earlier in life and diagnosing and treating osteoporosis well before a patient is scheduled for surgery.

A patient’s initial visit to their primary care doctor because of joint pain is an opportunity to check on and promote their bone health, given that they might be a candidate for surgery in the future, Dr. Bukata said.

Ahead of a scheduled surgery, patients can see endocrinologists or rheumatologists to receive medication to try to strengthen bones. Doctors may be limited in how much of a difference they can make in a matter of several weeks or months with these drugs, however. These patients still likely will need to be treated as if they have osteoporosis, Dr. Bukata said.

When surgeons realize that a patient has weaker bones while they are in the middle of an operation, they should emphasize the importance of bone health after the procedure, Dr. Bukata said.

Strengthening, maintaining, and protecting bone should be seen as a long-term investment in the patient’s success after a joint replacement. That said, “There is no clear evidence or protocol for us to follow,” she said. “The mantra at UCSD now is, let’s keep it simple. Get the patient on track. And then we can always refine things as we continue to treat the patient.”

Health systems should establish routines in which bone health is discussed before surgery in the way patient education programs address smoking cessation, nutrition, and weight management, Dr. Bukata said. Another step in the right direction could involve setting electronic medical records to automatically order assessments of bone health when a surgeon books a case.

Linda A. Russell, MD, rheumatologist and director of perioperative medicine at the Hospital for Special Surgery in New York, said periprosthetic fractures are a “complication we fear.”

“It’s a big deal to try to repair it,” Dr. Russell said. “Sometimes you need to revise the joint, or sometimes you need to put lots more hardware in.” Surgeons increasingly appreciate the need to pay attention to the quality of the bone before they operate, she said.

Nevertheless, Dr. Russell does not necessarily say that such cases call for alarm or particularly aggressive treatment regimens – just regular bone health evaluations before and after surgery to see whether patients have osteoporosis and are candidates for treatment.
 

Lifelong effort

In some ways, to address bone health at the time of surgery may be too late.

Bone health “is not something that you can have as an afterthought when you’re 75 years old,” said Elizabeth Matzkin, MD, chief of women’s sports medicine at Brigham and Women’s Hospital, in Boston.

The chance of being able to rebuild bone mass at that age is slim. If patients maximize bone density when they are young, they can afford to lose some bone mass each year as they age.

To that end, a healthy diet, exercise, not smoking, and cutting back on alcohol can help, she said.

For Dr. Matzkin, a fragility fracture is a red flag that the patient’s bone density is probably not optimal. In such cases, she prepares for various scenarios during surgery, such as a screw not holding in a low-density bone.

Recently published research reflects that prior fragility fractures are a significant risk factor for complications after surgery, including periprosthetic fractures.

Edward J. Testa, MD, of Brown University, Providence, R.I., and colleagues analyzed insurance claims to compare outcomes for 24,398 patients who had experienced a fragility fracture – that is, a break caused by low-velocity trauma such as a fall – during the 3 years before their TKA procedure and a matched group of patients who were similar in many respects but who had not had a fragility fracture in the 3 years before surgery.

Dr. Testa’s group found that a history of fragility fracture was associated with higher rates of complications in the year after surgery, including hospital readmissions (hazard ratio = 1.30; 95% CI, 1.22-1.38), periprosthetic fractures (odds ratio = 2.72; 95% CI, 1.89-3.99), and secondary fragility fractures (OR = 4.62; 95% CI, 4.19-5.12). Patients who had previously experienced fragility fractures also experienced dislocated prostheses (OR = 1.76; 95% CI, 1.22-2.56) and periprosthetic infections (OR = 1.49; 95% CI, 1.29-1.71) at higher rates.

The rates of complications were similar regardless of whether patients had filled a prescription for medications used to treat osteoporosis, including bisphosphonates, vitamin D replacement, raloxifene, and denosumab, the researchers reported.

The lack of a clear association between these treatments and patient outcomes could be related to an insufficient duration of pharmacotherapy before or after TKA, poor medication adherence, or small sample sizes, Dr. Testa said.

Given the findings, which were published online in the Journal of Arthroplasty, “patients with a history of fragility fracture should be identified and counseled appropriately for a possible increased risk of the aforementioned complications, and optimized when possible, prior to undergoing TKA,” Dr. Testa told this news organization. “Ultimately, the decision to move forward with surgery is far more complex than the identification of this sole, yet important, risk factor for certain postoperative, implant-related complications.”
 

Treatment gaps

Prior research has shown that women aged 70 years and older are at higher risk for periprosthetic fractures. Many women in this age group who could receive treatment for osteoporosis do not, and major treatment gaps exist worldwide, noted Neil Binkley, MD, with the University of Wisconsin–Madison, in a separate talk at the Santa Fe Bone Symposium.

Ensuring adequate protein intake and addressing the risk of falling are other measures that clinicians can take to promote healthy bones, apart from prescribing drugs, he said.

Unpublished data from one group show that nearly 90% of periprosthetic fractures may result from falls, while about 8% may be spontaneous. “We need to be thinking about falls,” Dr. Binkley said.

Dr. Bukata has consulted for Amgen, Radius, and Solarea Bio and has served on a speakers bureau for Radius. She also is a board member for the Orthopaedic Research Society and the American Academy of Orthopaedic Surgeons Board of Specialty Societies. Dr. Binkley has received research support from Radius and has consulted for Amgen.

For devout Muslims, praying multiple times a day is a lifelong observance and a core aspect of their faith. But osteoarthritis of the knee (KOA) can make kneeling and prostration challenging. To address this problem in an aging U.S. Muslim population, a multicenter team developed literature-based guidelines published online in Arthritis & Rheumatology.

In an interview, corresponding author Mahfujul Z. Haque, a medical student at Michigan State University, Grand Rapids, discussed the guide, which he assembled with Marina N. Magrey, MD, the Ronald Moskowitz Professor of Rheumatology at Case Western Reserve University, Cleveland, and orthopedic surgeon Karl C. Roberts, MD, president of West Michigan Orthopaedics in Grand Rapids, among others.

Could you detail the clinical and cultural context for these recommendations?

Mr. Haque: Muslims currently make up 1.1% of the U.S. population, or 3.45 million people. This guidance provides advice to Muslim patients with KOA in a culturally sensitive manner that can supplement standard care. Prayer, or Salah, is a religious obligation typically performed in 17-48 daily repetitions of squatting, floor sitting, full-knee flexion, and kneeling. For patients with KOA, prayer can be painful, and a few studies have found a link between these repeated movements and KOA progression.

Yet recommending stopping or limiting prayer is insensitive, so our group did a thorough literature search to identify easily implemented and culturally appropriate ways to ease praying.

Is there a traditional preference for praying on a hard surface?

Mr. Haque: Prayer can be performed on any surface that is clean and free from impurities. Cushioned and carpeted surfaces are permissible if the surface is somewhat firm and supportive for when worshippers prostrate themselves and put their faces on the ground. For example, compacted snow that wouldn’t allow the face to sink into it is permissible, but snow that is soft and would allow the face to sink in is not.

Have an increasing number of older patients raised the issue of knee pain during prayers?

Mr. Haque: We found no research on this in the literature. Anecdotally, however, two of our authors lead prayer in large Muslim communities in Detroit, and people often share with them that they feel discomfort during prayer and ask if there is anything they can do to limit this.

It is important to dispel the common myth that after total knee replacement one cannot kneel. About 20% of patients have some anterior knee discomfort after total knee arthroplasty, which can be exacerbated by kneeling, but kneeling causes no harm and can be done safely.

Could you outline the main recommendations?

Mr. Haque: These fall under three main categories: prayer surface, mechanics, and lifestyle modifications. The surface recommendations essentially advise using prayer rugs that provide cushioning or using cushioned kneepads.

The mechanics recommendations involve bracing with the palms down, standing up using the hands and knees, and guiding prayer motions with the hands. Chairs may be used as well.

Lifestyle recommendations outline home-exercise programs tailored to KOA and suggest the use of ice and compression during acute exacerbations.

Could these recommendations benefit other arthritic joints such as the wrists?

Mr. Haque: Anecdotally, our authors do not hear about pain in joints except for the knee and spine. To a limited extent, some of these recommendations may help patients with spinal arthritis as well.

What do you see as the greatest obstacle to implementation?

Mr. Haque: These recommendations, although permissible in the Muslim faith, are not part of traditional ritual and thus patients may simply forget to implement them. We advise physicians to ask patients which recommendations they are most likely to follow and to monitor how these have worked for them.

What is your best overall advice for broaching this issue with patients?

Mr. Haque: Holistic, functional, and culturally sensitive recommendations will be highly appreciated. Physicians are therefore encouraged to share this guidance with Muslim patients while using terms such as Salah, pronounced saa-laah, and Sajdah, pronounced sajduh and meaning prostration, and engage in a healthy dialogue.

These guidelines received no funding. The authors disclosed no competing interests relevant to their recommendations, but Dr. Magrey reported consulting and research relationships with private-sector companies outside of this work.

The effectiveness of up to three doses of COVID-19 vaccine was moderate overall and significantly lower among individuals with immunocompromising conditions, compared with the general population during the period of Omicron dominance, according to an analysis of data from more than 34,000 hospitalizations.

Previous studies have suggested lower COVID-19 vaccine effectiveness among immunocompromised individuals, compared with healthy individuals from the general population, but data from the period in which Omicron subvariants have been dominant are limited, wrote Amadea Britton, MD, of the Centers for Disease Control and Prevention’s COVID-19 Emergency Response Team, and colleagues.

The CDC currently recommends an expanded primary vaccine series of three doses of an mRNA vaccine, and the Advisory Committee on Immunization Practices has recommended a fourth dose with the new bivalent booster that contains elements of the Omicron variant, the researchers noted.

In a study published in the CDC’s Morbidity and Mortality Weekly Report, the researchers identified 34,220 adults with immunocompromising conditions who were hospitalized for COVID-19–like illness between Dec. 16, 2021, and Aug. 20, 2022. These conditions included solid malignancy (40.5%), hematologic malignancy (14.6%), rheumatologic or inflammatory disorder (24.4%), other intrinsic immune condition or immunodeficiency (38.5%), or organ or stem cell transplant (8.6%). They used data from the CDC’s VISION Network, a multistate database. The data include spring and summer 2022, when the BA.4 and BA.5 Omicron subvariants dominated other strains, and adults with immunocompromising conditions were eligible for a total of four vaccine doses (two primary doses and two boosters). The median age of the study population was 69 years, and 25.7%, 41.7%, and 7.0% had received two, three, and four doses, respectively, of COVID-19 vaccine.

Overall, vaccine effectiveness (VE) among immunocompromised patients was 34% after two vaccine doses, increasing to 71% during days 7-89 after a third dose, then declining to 41% 90 days or more after that dose.

During the full Omicron period, VE was 36% for 14 or more days after dose two, 69% for 7-89 days after dose three, and 44% for 90 or more days after dose three.

When VE was stratified by sublineage period, VE was higher 7 or more days after dose three during the predominance of BA.1 (67%), compared with VE during the dominant periods of BA.2/BA.2.12.1 (32%) and BA.4/BA.5 (35%).

In the later periods when Omicron BA.2/BA.2.12.1 and BA.4/BA.5 variants dominated, and individuals who had received three doses of vaccine were eligible for a fourth, VE against these variants was 32% 90 or more days after dose three and 43% 7 or more days after dose four.

VE was lowest among individuals with potentially more severe immunocompromising conditions, notably solid organ or stem cell transplants, the researchers wrote in their discussion.

The study findings were limited by several factors including the use of ICD-9 and -10 discharge diagnosis codes for immunocompromising conditions, potential confounding in VE models, lack of data on outpatient treatments such as nirmatelvir/ritonavir (Paxlovid), and lack of COVID-19 genomic sequencing data that may have affected which sublineage was identified, the researchers noted.

However, “this study confirms that even with boosters, immunocompromised adults, because of their weakened immune systems, are still at high risk of moderate to severe COVID,” said coauthor Brian Dixon, PhD, of the Regenstrief Institute and Indiana University Richard M. Fairbanks School of Public Health, Indianapolis, in a press release about the study.

“Given the incomplete protection against hospitalization afforded by monovalent COVID-19 vaccines, persons with immunocompromising conditions might benefit from updated bivalent vaccine booster doses that target recently circulating Omicron sublineages, in line with ACIP [Advisory Committee on Immunization Practices] recommendations,” the researchers concluded in the study.

The study was funded by the CDC. The researchers had no financial conflicts to disclose. The VISION Network is a collaboration between the CDC, the Regenstrief Institute, and seven health care systems across the United States: Columbia University Irving Medical Center (New York), HealthPartners (Wisconsin), Intermountain Healthcare (Utah), Kaiser Permanente Northern California, Kaiser Permanente Northwest (Washington State), the University of Colorado, and Paso Del Norte Health Information Exchange (Texas).

A new study based on U.S. veterans’ medical records adds to the evidence for a link between gout – especially poorly controlled cases – and cardiovascular disease (CVD) risk, Tate Johnson, MD, reported at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network.

Gout was associated with a 68% increased risk of heart failure (HF) hospitalization, 25% increased risk of HF-related death, and a 22% increased risk of major adverse cardiovascular events (MACE), said Dr. Johnson, of the division of rheumatology at the University of Nebraska, Omaha.

Poorly controlled serum urate was associated with a higher risk of cardiovascular events, regardless of the use of urate-lowering therapy (ULT). He said more research is needed to see if there is a causal link between gout, hyperuricemia – or its treatment – and CVD risk.

Dr. Johnson and colleagues used records from the Veterans Health Administration for this study. They created a retrospective, matched cohort study that looked at records dating from January 1999 to September 2015. Patients with gout (≥ 2 ICD-9 codes) were matched 1:10 on age, sex, and year of VHA enrollment to patients without a gout ICD-9 code or a record of receiving ULT. They matched 559,243 people with gout to 5,407,379 people who did not have a diagnosis or a recorded treatment for this condition.

Over 43,331,604 person-years, Dr. Johnson and colleagues observed 137,162 CVD events in gout (incidence rate 33.96 per 1,000 person-years) vs. 879,903 in non-gout patients (IR 22.37 per 1,000 person-years). Gout was most strongly associated with HF hospitalization, with a nearly threefold higher risk (hazard ratio, 2.78; 95% confidence interval, 2.73-2.83), which attenuated but persisted after adjustment for additional CVD risk factors (adjusted hazard ratio, 1.68; 95% CI, 1.65-1.70) and excluding patients with prevalent HF (aHR, 1.60; 95% CI, 1.57-1.64).

People with gout were also at higher risk of HF-related death (aHR, 1.25; 95% CI, 1.21-1.29), MACE (aHR, 1.22; 95% CI, 1.21-1.23), and coronary artery disease–related death (aHR, 1.21; 95% CI, 1.20-1.22).

Among people with gout in the study, poor serum urate control was associated with a higher risk of all CVD events, with the highest CVD risk occurring in patients with inadequately controlled serum urate despite receipt of ULT, particularly related to HF hospitalization (aHR, 1.43; 95% CI, 1.34-1.52) and HF-related death (aHR, 1.47; 95% CI, 1.34-1.61).

Limits of the study include the generalizability of the study population. Reflecting the VHA’s patient population, 99% of the cohort were men, with 62% of the gout group and 59.4% of the control group identifying as White and non-Hispanic.

The study provides evidence that may be found only by studying medical records, Richard J. Johnson, MD, of the University of Colorado at Denver, Aurora, said in an interview.

Dr. Richard Johnson, who is not related to the author, said that only about one-third of people with gout are adequately treated, and about another one-third take urate-lowering therapy (ULT) but fail to get their serum urate level under control. But it would be unethical to design a clinical trial to study CVD risk and poorly controlled serum urate without ULT treatment.

“The only way you can figure out if uric acid lowering is going to help these guys is to actually do a study like this where you see the ones who don’t get adequate treatment versus adequate treatment and you show that there’s going to be a difference in outcome,” he said.

Dr. Richard Johnson contrasted this approach with the one used in the recently reported study that appeared to cast doubt on the link between serum uric acid levels and cardiovascular disease. The ALL-HEART trial found that allopurinol, a drug commonly used to treat gout, provided no benefit in terms of reducing cardiovascular events in patients with ischemic heart disease. But these patients did not have gout, and that was a critical difference, he said.

He noted that it was not surprising that the results of ALL-HEART were negative, given the study design.

“The ALL-HEART study treated people regardless of their uric acid level, and they also excluded subjects who had a history of gout,” he said. “Yet the risk associated with uric acid occurs primarily among those with elevated serum uric acid levels and those with gout.”

The study received funding from the Rheumatology Research Foundation and the VHA. Neither Dr. Tate Johnson nor Dr. Richard Johnson had any relevant disclosures.

A new study based on U.S. veterans’ medical records adds to the evidence for a link between gout – especially poorly controlled cases – and cardiovascular disease (CVD) risk, Tate Johnson, MD, reported at the annual research symposium of the Gout, Hyperuricemia, and Crystal Associated Disease Network.

Gout was associated with a 68% increased risk of heart failure (HF) hospitalization, 25% increased risk of HF-related death, and a 22% increased risk of major adverse cardiovascular events (MACE), said Dr. Johnson, of the division of rheumatology at the University of Nebraska, Omaha.

Poorly controlled serum urate was associated with a higher risk of cardiovascular events, regardless of the use of urate-lowering therapy (ULT). He said more research is needed to see if there is a causal link between gout, hyperuricemia – or its treatment – and CVD risk.

Dr. Johnson and colleagues used records from the Veterans Health Administration for this study. They created a retrospective, matched cohort study that looked at records dating from January 1999 to September 2015. Patients with gout (≥ 2 ICD-9 codes) were matched 1:10 on age, sex, and year of VHA enrollment to patients without a gout ICD-9 code or a record of receiving ULT.
