Liver-related deaths declined and liver transplant waitlist inequities decreased in states that implemented Medicaid expansion under the Affordable Care Act (ACA), results of an innovative study showed.

About 1 year after Medicaid expansion began on Jan. 1, 2014, the rate of liver-related mortality in 18 states that took advantage of expanded coverage began to decline, whereas the rate of liver-related deaths in 14 states that did not expand Medicaid continued to climb, reported Nabeel Wahid, MD, a resident at Weill Cornell Medicine, New York.

The differences in liver-related mortality between Medicaid expansion and nonexpansion states was particularly pronounced in people of Asian background, in Whites, and in African Americans, he said in an oral abstract presentation during the virtual annual meeting of the American Association for the Study of Liver Diseases.

“The expansion of government health care programs such as Medicaid may improve liver-related mortality and liver transplant waitlist placement,” he said.

The implementation of the ACA, also known as Obamacare, resulted in “a pretty dramatic increase in the number of Americans with health insurance today, and there’s a lot of literature out there looking at a variety of domains throughout health care that have found that Medicaid expansion increased access and decreased disparities in care,” he added.

For example, a report published in 2019 by the nonpartisan National Bureau of Economic Research Priorities showed a significant reduction in disease-related deaths in Americans aged 55-64 in Medicaid expansion states compared with nonexpansion states.

In addition as previously reported, before Medicaid expansion African Americans were 4.8% less likely than were Whites to receive timely cancer treatment, defined as treatment starting within 30 days of diagnosis of an advanced or metastatic solid tumor. After Medicaid expansion, however, the difference between the racial groups had dwindled to just 0.8% and was no longer statistically significant.

“However, specifically in the realm of liver transplantation and liver disease, there’s very limited literature showing any sort of significant impact on care resulting from Medicaid expansion,” Dr. Wahid said.
 

Listing-to-death ratio

To test their hypothesis that Medicaid expansion decreased racial disparities and improved liver-related deaths and transplant waitlist placement, Dr. Wahid and colleagues compared liver-related deaths and liver transplants listings between Medicaid expansion and nonexpansion states in the 5 years before expansion (2009-2013) and in the 5 years after expansion (2014-2018). They excluded all states without transplant centers as well as patients younger than 25 or older than 64, who were likely to be covered by other types of insurance.

They obtained data for listing from the United Network for Organ Sharing (UNOS) and on end-stage liver disease from the Centers for Disease Control and Prevention’s WONDER database.

They also used a novel measure called the listing-to-death ratio (LDR), a surrogate endpoint for waitlist placement calculated as the ratio of listings for liver transplantation relative to the number of deaths from liver disease, with a higher LDR score corresponding to improved waitlist placement.

They found that throughout the entire study period, Medicaid expansion states had lower liver-related deaths, higher liver transplant listings, and higher LDR.

Using joinpoint regression to examine changes at a specific time point, the investigators determined that the annual percentage change in liver-related deaths increased in both nonexpansion states (mean 4.3%) and expansion states (3.0%) before 2014. However, beginning around 2015, liver-related deaths began to decline in expansion states by a mean of –0.6%, while they continued on an upward trajectory in the nonexpansion states, albeit at a somewhat slower pace (mean APC 2% from 2014 through 2018).

Among all racial and ethnic groups (Whites, African Americans, Hispanics, and Asians) liver-related deaths increased from 2014 to 2018 in nonexpansion states, with the highest annual percentage change in Asians, at slightly more than 8%.

In contrast, among Asians in the expansion states, liver-related deaths over the same period increased by less than 1%, and in both Whites and African Americans liver-related deaths declined.

In addition, starting in 2015, the annual percent change in LDR increased only in expansion states primarily because of fewer end-stage liver disease deaths (the denominator in the LDR equation) rather than increased listings (the numerator).
 

‘No-brainer’

A gastroenterologist who was not involved in the study said that there are two key points in favor of the study.

“The obvious message is that transplant is costly, and patients need to be insured to get a liver transplant, because nobody is paying for this out of pocket. So if more candidates are insured that will reduce disparities and improve access to liver transplant for those who need it,” said Elliot Benjamin Tapper, MD, of the University of Michigan, Ann Arbor.

“It’s a no-brainer that the lack of insurance accessibility for the most vulnerable people in the United States meant that they were dying of cirrhosis instead of being transplanted,” he said in an interview.

He also commended the authors on their use of population-based data to identify outcomes.

“We know how many people are listed for liver transplant, but we don’t know how many people could have been listed. We know how many people are transplanted, but we don’t know how many people with decompensated cirrhosis should have been given that chance. We lacked that denominator,” he said.

“The innovation that makes this particular paper worthwhile is that in the absence of that denominator, they were able to construct it, so we can know from other data sources distinct from the waitlist rolls how many people are dying of cirrhosis,” he added.

No study funding source was reported. Dr. Wahid and Dr. Tapper reported no conflicts of interest.

The all-consuming news about SARS-CoV-2 and COVID-19 has overshadowed other viral pathogens that are the cause of severe or fatal lower respiratory infections (LRI) including human metapneumovirus (HMPV).

“MPV is really a leading cause of LRI not just in children but in adults, with high mortality rates in the frail elderly, long-term care facilities, and cancer patients with pneumonia, “ said John Williams, MD, from the department of pediatric infectious diseases at the University of Pittsburgh Medical Center.

“Right now we have no effective antivirals. There are monoclonal antibodies in development that my group and others have discovered. In fact, some of these treat MPV and RSV [respiratory syncytial virus], so we may have good options,” he said in an online presentation during an annual scientific meeting on infectious diseases.

The virus preys, wolf-like, on the most vulnerable patients, including children and frail elderly adults, as well as other adults with predisposing conditions, he said.

HMPV causes acute respiratory illnesses in approximately 2%-11% of hospitalized adults, 3%-25% of organ transplant recipients or cancer patients, 4%-12% of chronic obstructive pulmonary disease exacerbations, 5%-20% of asthma exacerbations, and it has been identified in multiple outbreaks at long-term care facilities.


 

Relative newcomer

Metapneumovirus was isolated and discovered from children with respiratory tract disease in the early 2000s. Once included in the family of paramyxoviruses (including measles, mumps, Nipah virus, and parainfluenza virus 1-4), HMPV and RSV are now classified as pneumoviruses, based on gene order and other characteristics, Dr. Williams explained.

Various studies have consistently placed the prevalence of HMPV ranging from 5%-14% in young children with LRI, children hospitalized for wheezing, adults with cancer and LRI, adults with asthma admissions, children with upper respiratory infections, and children hospitalized in the United States and Jordan for LRI, as well as children hospitalized in the United States and Peru with acute respiratory infections.

A study tracking respiratory infections in a Rochester, N.Y., cohort from 1999 through 2003 showed that healthy elderly patients had and annual incidence of HMPV infections of 5.9%, compared with 9.1% for high-risk patients, 13.1% for young patients, and 8.5% among hospitalized adult patients.

“These percentages are virtually identical to what has been seen in the same cohort for respiratory syncytial virus, so in this multiyear prospective cohort, metapneumovirus was as common as RSV,” Dr. Williams said.

Although the incidences of both HMPV and RSV were lower among hospitalized adults “clinically, we can’t tell these respiratory viruses apart. If we know it’s circulating we can make a guess, but we really can’t discriminate them,” he added.

In the Rochester cohort the frequency of clinical symptoms – including congestion, sore throat, cough, sputum production, dyspnea, and fever – were similar among patients infected with HMPV, RSV, or influenza A, with the exception of a slightly higher incidence of wheezing (80%) with HMPV, compared with influenza.

“I can tell you as a pediatrician, this is absolutely true in children, that metapneumovirus is indistinguishable from other respiratory viruses in kids,” he said.
 

Fatalities among older adults

As noted before, HMPV can cause severe and fatal illness in adults. For example, during an outbreak in North Dakota in 2016, 3 of 27 hospitalized adults with HMPV (median age, 69 years) died, and 10 required mechanical or noninvasive ventilation.

In a study from Korea comparing outcomes of severe HMPV-associated community-acquired pneumonia (CAP) with those of severe influenza-associated CAP, the investigators found that 30- and 60-day mortality rates were similar between the groups, at 24% of patients with HMPV-associated CAP and 32.1% for influenza-associated CAP, and 32% versus 38.5%, respectively.

Patients at high risk for severe disease or death from HMPV infection include those over 65 years, especially frail elderly, patients with chronic obstructive pulmonary disease, immunocompromised patients, and those with cardiopulmonary diseases such as congestive heart failure.
 

Supportive care only

“Do we have anything for treatment? The short answer is, No,” Dr. Williams.

Supportive care is currently the only effective approach for patients with severe HMPV infection.

Ribavirin, used to treat patients with acute RSV infection, has poor in vitro activity against HMPV and poor oral bioavailability and hemolysis, and there are no randomized controlled trials to support its use in this situation.

“It really can’t be recommended, and I don’t recommend it,” he said.
 

Virology may still help

Mark J. Siedner, MD, an infectious diseases physician at Mass General and associate professor of medicine at Harvard Medical School, both in Boston, who was not involved in the study, said that, despite the inability to clinically distinguish HMPV from RSV or influenza A, there is still clinical value to identifying HMPV infections.

“We spend millions of dollar each year treating people for upper respiratory tract infections, often with antibacterials, sometimes with antivirals, but those have costs to the health care system, and they also have costs in terms of drug resistance,” he said in an interview seeking objective commentary.

“Diagnostic tests that determine the actual source or the cause of these upper respiratory tract infections and encourage both patients and physicians not to be using antibiotics have value,” he said.

Identifying the pathogen can also help clinicians take appropriate infection-control precautions to prevent patient-to-clinician or patient-to-patient transmission of viral infections, he added.

Dr. Williams’ research is supported by the National Institutes of Health, Henry L. Hillman Foundation, and Asher Krop Memorial Fund of Children’s Hospital of Pittsburgh. Dr. Williams and Dr. Siedner reported no relevant conflict of interest disclosures.

Large-scale scanning of serum proteins offers a potential method for noninvasive screening and monitoring of patients with nonalcoholic steatohepatitis (NASH), the technique’s developers claim.

By scanning for about 5,000 proteins in nearly 3,000 samples from patients enrolled in studies from the Clinical Research Network in NASH (NASH CRN), Rachel Ostroff, PhD, and colleagues from SomaLogic in Boulder, Colo., created four protein models that mimic results of the major pathologic findings in liver tissue biopsy.

“Concurrent positive results from the protein models had performance characteristics of ‘rule-out’ tests for pathologists’ diagnosis of NASH. These tests may assist in new drug development and medical intervention decisions,” they wrote in a late-breaking poster presented at the virtual annual meeting of the American Association for the Study of Liver Diseases.

“There is no single noninvasive method that can accurately and simultaneously capture steatosis, inflammation, hepatocyte ballooning and fibrosis, the four major pathologic components assessed by biopsy. Each of these is relevant to the multiple mechanisms targeted in drug development for NASH,” they wrote.

To see whether large-scale protemoics could serve as an alternative to invasive liver biopsy for use in clinical trials or in longitudinal studies of NASH, they used a modified aptamer proteomics platform to scan for liver-related proteins. Aptamers are olignonucleotide or peptide molecules designed to home in on a specific target.

They scanned for approximately 5,000 proteins in 2,852 serum samples from 638 patients in a NASH CRN natural history cohort, and in patients enrolled in two NASH treatment trials: the PIVENS trial, which is evaluating pioglitazone versus vitamin E and placebo in nondiabetic patients, and the FLINT trial, which is comparing obeticholic acid with placebo. All of the patients in the natural history cohort and half of all patients in the clinical trial cohorts were included in the training sets, with the remaining half included in the validation set.

The accuracy of the models, as measured by the area under the curve (AUC) of receiver operating characteristics in the training and validation sets, respectively, were as follows:

• Fibrosis: AUC 0.92/0.85.
• Steatosis: AUC 0.95/0.79.
• Inflammation: AUC 0.83/0.72.
• Hepatocyte Ballooning: AUC 0.87/0.83.

“A concurrent positive score for steatosis, inflammation and ballooning predicted the biopsy diagnosis of NASH with an accuracy of 73%,” Ostroff and colleagues wrote.

They also found that model scores applied over time showed improvements in symptoms in the patients on active therapies in the clinical trials, compared with patients on placebo.

A specialist in liver pathology and nonalcoholic fatty liver disease who was not involved in the study said in an interview that she finds the results highly promising.
 

Impressive results

Elizabeth M. Brunt, MD, emeritus professor of pathology and immunology at Washington University in St. Louis, was a member of the NASH CRN when SomaLogic first proposed using the groups’ data for this study.

“I was impressed with them then, and I am very impressed with what they’re presenting here, and I can’t say that about all the noninvasive tests,” she said. “I think a lot of noninvasive tests are way over-simplifying what NASH is.”

She acknowledged that, although she spent much of her career performing liver biopsies, “you can’t biopsy every single patients who you suspect of having NASH, or certainly if you want to follow them over time – it’s unrealistic,” she said in an interview.

Although the protein scanning method cannot – and is not intended to – replace a well-conducted biopsy with the interpretation of a skilled pathologist, the proteins the company investigators identified can reflect the dynamic nature of liver disease and the liver’s ability to heal itself with a high degree of accuracy and hold promise for both screening patients and for monitoring responses to therapy, Dr. Brunt said.

The study was sponsored by SomaLogic. The authors are employees of the company. Dr. Brunt had no relevant disclosures.

Patients with Sjögren’s syndrome can be categorized into four distinct symptom clusters – independent of age, sex, and some disease manifestations – that may both improve symptom relief and aid in the development of targeted therapies, investigators reported.

Analysis of data from a survey conducted by the Sjögren’s Foundation identified four symptom clusters based on the grouping of five common characteristics: anxiety, depression, pain, fatigue, and dryness, Sara S. McCoy, MD, of the University of Wisconsin–Madison, and colleagues reported.

“Verification of features unique to each Sjögren’s cluster might provide guidance for future cluster-targeted therapy,” Dr. McCoy said in an oral abstract presentation during the virtual annual meeting of the American College of Rheumatology.

The dearth of Food and Drug Administration–approved disease-modifying therapies for Sjögren’s syndrome can be attributed in part to the small number of patients with extraglandular disease manifestations, the heterogeneity of disease, and the failure of available therapy to improve common symptoms such as fatigue, dryness, quality-of-life decrements, anxiety and depression, she said.
 

Symptom clusters verify smaller study’s findings

Dr. McCoy and colleagues explored whether symptom clusters identified in a 2019 study from the United Kingdom would apply to a larger U.S. population.

In the U.K. study, Jessica R. Tarn, PhD, and colleagues performed a hierarchical cluster analysis to identify subgroups among 608 patients in the U.K. Primary Sjögren’s Syndrome Registry and in 396 patients in two independent validation cohorts from Norway and France.

They identified four subgroups they categorized as low symptom burden, high symptom burden, dryness dominant with fatigue, and pain dominant with fatigue, and reported that the groups showed significant difference in serum and transcriptomic markers.

In the U.S. study, McCoy et al. sought to verify the symptom-based cluster and report on differences in key measures between the groups. They used data from a survey by the Sjögren’s Foundation of 2,961 adults with self-reported Sjögren’s syndrome. The investigators then used an unsupervised hierarchical clustering method to identify the optimal phenotypically similar clusters based on patient-reported severity of anxiety (from never to daily), depression (never to daily), pain on a visual analog scale (0 to 10), fatigue on a VAS, and dryness on a VAS. They collected data on demographics, medications, quality of life, and Sjögren’s-specific symptom frequency and systemic manifestations within each cluster, and identified cluster differences controlled for age, sex, race, and Social Security disability.

They identified four symptom-based clusters from 2,806 participants for whom complete data on the five key symptoms were available:

• Cluster 1 patients (prevalence, 30%) had high symptom burden in all categories.
• Cluster 2 patients (22%) had high anxiety and depression (22%), with some fatigue.
• Cluster 3 patients (34%) had predominant high dryness and fatigue.
• Cluster 4 patients (14%) had low symptom burden.

“We found that clusters differed in Sjögren’s-specific symptoms,” Dr. McCoy said.

For example, patients in the high-symptom-burden cluster had, as the name implies, an overall higher burden of symptoms among all major ocular, oral, and other dryness symptoms, as well as systemic organ system symptoms, whereas patients in the low-symptom-burden group consistently had the lowest levels of symptoms across the spectrum.

“We also noticed significant differences in systemic medication use. High symptom burden and high dryness and fatigue had higher use of systemic therapies targeting dryness, as might be expected,” she said.

The highest corticosteroid use was in the high-symptom-burden group, while hydroxychloroquine use was highest in the high-anxiety/depression group. Antidepressant use was also high in these two groups.

In addition, 35% of patients in the high-symptom-burden group used prescription opioid analgesics, compared with just 7% in the low-symptom-burden group.

The categories from low to high symptom burden also significantly correlated with quality-of-life measures, including Social Security Disability enrollment, emotional burden of disease, effects of disease on independence, and effects of Sjögren’s on relationships with family and friends (P < .001 for all).

Systemic manifestations of disease differed significantly among the groups for inflammatory arthritis, interstitial lung disease, and neuropathy, but there were no significant differences in the incidence of leukopenia or lymphoma.

The investigators plan to perform symptom-based cluster analysis with validated Sjögren’s syndrome populations, and propose studies to define phenotypic features of distinct clusters “to better define subsets of this heterogeneous disease, and ultimately inform targeted therapy,” Dr. McCoy concluded.
 

Opportunity to tailor practice and research

During the question-and-answer period following the presentation, Gabriela Hernandez-Molina, MD, of the Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán in Mexico City, commented that “fatigue and pain might be also attributed to other comorbidities in these patients such as fibromyalgia,” and asked Dr. McCoy to comment on that.

“That’s exactly what we’re driving at,” Dr. McCoy replied. “Fatigue and pain frequently affect how patients experience their disease, and it would be beneficial to take this into account when we evaluate patients, and also for the studies that we’re performing, as well as future ‘-omic’ studies – transcriptomics and what-not – there’s potential here to take that type of patient we frequently see and try to tailor our clinical practice and our research to clearly what we’re seeing in practice, which is these other comorbidities.”

Dana DiRenzo, MD, from Johns Hopkins University, Baltimore, who moderated the session, asked how the information is changing the management of patients with Sjögren’s syndrome in clinic.

Dr. McCoy said that the study was based on self-reported data that can introduce bias, and that she and colleagues plan to validate the results before applying them to clinical care.

The study was supported by grants from the National Institutes of Health and the University of Wisconsin. Dr. McCoy disclosed consulting fees from Novartis and Bristol-Myers Squibb. Dr. Hernandez-Molina and Dr. DiRenzo reported no relevant disclosures.

A draft guideline for the management of patients with juvenile idiopathic arthritis reflects changes in therapy away from reliance on NSAIDs and glucocorticoids and toward earlier introduction of biologic disease-modifying antirheumatic drugs (DMARDs).

The guideline, described in an oral session during the virtual annual meeting of the American College of Rheumatology, contains weighted recommendations for the treatment of JIA, including therapeutic approaches for oligoarthritis, tempromandibular joint (TMJ) arthritis, and systemic JIA (sJIA). The recommendations were the result of expert consensus and literature review using GRADE methodology, with input from clinicians, as well as patients and parents.

“Although evidence remains very low and many recommendations are conditional, the inclusion of parents and patients in the decision-making process strengthens their validity,” said project principal investigator Karen Onel, MD, of the Hospital for Special Surgery and Weill Cornell Medicine, both in New York.

She added that “it’s important to remember that these guidelines are meant to be guidelines; clinical care remains in the hands of the provider and the patient, and we endorse the importance of shared decision-making in coming to these agreements.”

Dr. Onel outlined key recommendations for patients for whom a diagnosis of JIA has already been made and who have no contraindications to recommended therapies. The strength of the recommendations (strong or conditional) and evidence levels (high, moderate, low, very low) were also reported.
 

Oligoarthritis with fewer than five involved joints

For these patients, intra-articular glucocorticoids (IAGC) are recommended as a part of initial therapy (strong, very low evidence).

Triamcinolone acetonide is the preferred agent in this situation (strong, low evidence).

The guideline also has a conditional recommendation (very low evidence) for a trial of consistent NSAIDS as part of initial therapy and a conditional recommendation against oral glucocorticoids for initial therapy (very low evidence).

Patients with no or incomplete responses or intolerance to NSAIDS and/or IAGC may be tried on a nonbiologic DMARD (strong, very low evidence), with methotrexate as the preferred agent (conditional, low evidence).

If the patient has no response or an inadequate response to at least one nonbiologic DMARD, biologic DMARDs are recommended (strong, very low evidence), with no preferred agent.

The guideline also conditionally recommends (all with very low evidence) using risk factors and validated disease activity measures to guide treatment decisions, as well as imaging guidance of joints that are difficult to access or to localize the distribution of inflammation.
 

TMJ arthritis

For patients with temporomandibular joint arthritis, isolated or not, IAGCs are conditionally recommended as part of initial therapy (very low evidence) with no preferred agents. The guideline also conditionally recommends in favor of a trial of consistent NSAIDs, and against oral glucocorticoids in initial therapy (evidence for both very low).

Recommendations for patients with TMJ with no or an incomplete response to the initial therapy are the same as for patients with oligoarthritis, with no preferred agent.
 

sJIA without macrophage activation syndrome

For patients with sJIA without macrophage activation syndrome (MAS), NSAIDS are conditionally recommended as initial monotherapy (very low evidence). Biologic DMARDS (including interleukin-1 and IL-6 inhibitors) are also recommended, conditionally, as initial monotherapy, with no preferred agent.

If the patient has an inadequate response or intolerance to NSAIDS and at least one nonbiologic DMARD, a single biologic DMARD is recommended over a combination of nonbiologic therapies (strong, very low evidence).

“However, there have been reports of emergent, highly severe lung disease associated with the use of biologics in children with systemic JIA, especially in those who are young, with chronic macrophage activation syndrome, and those with trisomy 21. More information is needed to clarify the safety of these agents,” Dr. Onel said.

There is a conditional recommendation against oral glucocorticoids as initial monotherapy, and strong recommendation against nonbiologic DMARDs as initial monotherapy (both very low evidence).

sJIA with MAS

“Macrophage activation syndrome is a major cause of morbidity and mortality for children with sJIA. Cytokine storm and secondary hemophagocytic syndrome can be seen with any rheumatic disease, but are most commonly seen with sJIA,” she said.

The features of MAS include fever, high ferritin levels, cytopenias, elevated liver-function test results, and high triglyceride levels.

For these patients, glucocorticoids are recommended as initial monotherapy (conditional, very low evidence). Biologic DMARDs (IL-1 and IL-6 inhibitors) are recommended over calcineurin inhibitors for achieving inactive disease and resolution of MAS (conditional, very low evidence). There is no preferred agent.

For patients with residual arthritis and an incomplete response to IL-1 or IL-6 inhibitors, biologic and nonbiologic DMARDs are recommended over chronic glucocorticoids (strong, very low evidence). There is no preferred agent.

After an MAS inactive disease state has been attained, the guideline recommends tapering and discontinuing glucocorticoids (strong, very low evidence) and the same for biologic DMARDs (conditional, very low evidence).
 

All children with JIA

In addition to the recommendations on specific clinical situations, the guideline includes recommendations for all children with JIA on medication monitoring, laboratory testing, and infection screening, as well as immunization and nonpharmacologic management.

A rheumatologist who was not involved in development of the guidelines commented on the importance of optimal management of JIA.

“Children are not immune from devastating rheumatic diseases, and the largest group is juvenile idiopathic arthritis. In my clinic, I have patients in their 30s, 40s, and 50s who have adult persistence of their arthritis from JIA who have permanent joint damage and even ongoing hard-to-control disease, and it has to do with the lack of therapies in the 1990s,” said Donald Thomas, MD, from Arthritis and Pain Associates of Prince George’s County (Md.).

“Today when we get a young adult transitioned from the pediatric clinic they’re usually in remission or have low disease activity because these treatments have paralleled those of our adult RA patients. Yet they do [provide clinicians with] unique challenges, with stunting of growth, macrophage activiation syndrome, and having to work with family members of the patient,” he said at a press briefing he moderated following the presentation of RA and JIA guidelines.

Eyal Muscal, MD, associate professor of pediatrics and rheumatology at Baylor College of Medicine, Houston, said in an interview that the guidelines clarify recommendations about earlier use of targeted therapies, primarily biologics.

“This will not change care, but hopefully remind all to adopt such strategies. Yet earlier utilization of often expensive biologic agents is delayed by administrative and insurance hurdles in the U.S. and access to these medications globally. I hope the guidelines will enhance advocacy on a state, national, and global stage,” he said when asked for comment.

The guideline development process is supported by ACR. Dr. Onel, Dr. Thomas, and Dr. Muscal reported no relevant conflicts of interest.

A draft guideline for the management of patients with juvenile idiopathic arthritis reflects changes in therapy away from reliance on NSAIDs and glucocorticoids and toward earlier introduction of biologic disease-modifying antirheumatic drugs (DMARDs).

The guideline, described in an oral session during the virtual annual meeting of the American College of Rheumatology, contains weighted recommendations for the treatment of JIA, including therapeutic approaches for oligoarthritis, tempromandibular joint (TMJ) arthritis, and systemic JIA (sJIA). The recommendations were the result of expert consensus and literature review using GRADE methodology, with input from clinicians, as well as patients and parents.

“Although evidence remains very low and many recommendations are conditional, the inclusion of parents and patients in the decision-making process strengthens their validity,” said project principal investigator Karen Onel, MD, of the Hospital for Special Surgery and Weill Cornell Medicine, both in New York.

She added that “it’s important to remember that these guidelines are meant to be guidelines; clinical care remains in the hands of the provider and the patient, and we endorse the importance of shared decision-making in coming to these agreements.”

Dr. Onel outlined key recommendations for patients for whom a diagnosis of JIA has already been made and who have no contraindications to recommended therapies. The strength of the recommendations (strong or conditional) and evidence levels (high, moderate, low, very low) were also reported.
 

Oligoarthritis with fewer than five involved joints

For these patients, intra-articular glucocorticoids (IAGC) are recommended as a part of initial therapy (strong, very low evidence).

Triamcinolone acetonide is the preferred agent in this situation (strong, low evidence).

The guideline also has a conditional recommendation (very low evidence) for a trial of consistent NSAIDS as part of initial therapy and a conditional recommendation against oral glucocorticoids for initial therapy (very low evidence).

Patients with no or incomplete responses or intolerance to NSAIDS and/or IAGC may be tried on a nonbiologic DMARD (strong, very low evidence), with methotrexate as the preferred agent (conditional, low evidence).

If the patient has no response or an inadequate response to at least one nonbiologic DMARD, biologic DMARDs are recommended (strong, very low evidence), with no preferred agent.

The guideline also conditionally recommends (all with very low evidence) using risk factors and validated disease activity measures to guide treatment decisions, as well as imaging guidance of joints that are difficult to access or to localize the distribution of inflammation.
 

TMJ arthritis

For patients with temporomandibular joint arthritis, isolated or not, IAGCs are conditionally recommended as part of initial therapy (very low evidence) with no preferred agents. The guideline also conditionally recommends in favor of a trial of consistent NSAIDs, and against oral glucocorticoids in initial therapy (evidence for both very low).

Recommendations for patients with TMJ with no or an incomplete response to the initial therapy are the same as for patients with oligoarthritis, with no preferred agent.
 

sJIA without macrophage activation syndrome

For patients with sJIA without macrophage activation syndrome (MAS), NSAIDS are conditionally recommended as initial monotherapy (very low evidence). Biologic DMARDS (including interleukin-1 and IL-6 inhibitors) are also recommended, conditionally, as initial monotherapy, with no preferred agent.

If the patient has an inadequate response or intolerance to NSAIDS and at least one nonbiologic DMARD, a single biologic DMARD is recommended over a combination of nonbiologic therapies (strong, very low evidence).

“However, there have been reports of emergent, highly severe lung disease associated with the use of biologics in children with systemic JIA, especially in those who are young, with chronic macrophage activation syndrome, and those with trisomy 21. More information is needed to clarify the safety of these agents,” Dr. Onel said.

There is a conditional recommendation against oral glucocorticoids as initial monotherapy, and strong recommendation against nonbiologic DMARDs as initial monotherapy (both very low evidence).

sJIA with MAS

“Macrophage activation syndrome is a major cause of morbidity and mortality for children with sJIA. Cytokine storm and secondary hemophagocytic syndrome can be seen with any rheumatic disease, but are most commonly seen with sJIA,” she said.

The features of MAS include fever, high ferritin levels, cytopenias, elevated liver-function test results, and high triglyceride levels.

For these patients, glucocorticoids are recommended as initial monotherapy (conditional, very low evidence). Biologic DMARDs (IL-1 and IL-6 inhibitors) are recommended over calcineurin inhibitors for achieving inactive disease and resolution of MAS (conditional, very low evidence). There is no preferred agent.

For patients with residual arthritis and an incomplete response to IL-1 or IL-6 inhibitors, biologic and nonbiologic DMARDs are recommended over chronic glucocorticoids (strong, very low evidence). There is no preferred agent.

After an MAS inactive disease state has been attained, the guideline recommends tapering and discontinuing glucocorticoids (strong, very low evidence) and the same for biologic DMARDs (conditional, very low evidence).

Adding the immunomodulator mycophenolate mofetil (MMF) to therapy with pegloticase (Krystexxa) may improve outcomes in patients with refractory gout, results of the proof-of-concept RECIPE trial suggest.

In the phase 2 trial, 19 of 22 patients randomized to received pegloticase and MMF achieved the primary outcome of serum uric acid levels below 6 mg/dL at week 12, compared with 4 of 10 patients assigned to pegloticase and placebo, reported Puja Khanna MD, MPH, of the University of Michigan, Ann Arbor, and colleagues.

“The use of MMF was associated with statistically significant and clinically meaningful impact on the proportion of subjects who achieved and maintained a serum urate of less than 6 mg/dL. Short-term concomitant use of MMF with pegloticase was generally well tolerated, and the estimated rates of adverse events were comparable between the groups,” she said during the virtual annual meeting of the American College of Rheumatology.

Pegloticase is a pegylated recombinant form of porcine uricase that has been shown to be effective in the treatment of gout in patients for whom other therapies have failed.

The drug’s use is limited, however, by immunogenicity, with high antipegloticase antibody titers associated with a loss of response.

“The PEG portion of the molecule, the polyethylene glycol component, can initiate an immune response that would cause significant infusion reactions and preclude further use of the medication for our patients,” explained Suleman Bhana, MD, a rheumatologist with Crystal Run Healthcare in New York’s Hudson Valley, who was not involved in the study.

“By trying to attenuate that immune response by whatever means one can, that could reduce the risk of these infusion reactions and lead to longevity and continuing efficacy of the medication,” he said.
 

Study details

The RECIPE trial was designed to test whether concomitant immunomodulation could prolong the efficacy of pegloticase therapy by dampening immune reactions.

Investigators enrolled patients 18 years and older who met 2015 ACR/European League Against Rheumatism gout classification criteria and had chronic refractory disease, defined as having symptoms inadequately controlled with oral urate-lowering therapy or a contraindication to ULT.

A total of 42 patients from five rheumatology practices were screened, and 35 were randomized on a 3:1 basis. In the intention-to-treat analysis of the results, the investigators included 32 patients: 22 in the MMF/pegloticase group and 10 placebo-treated controls who had received at least one dose of pegloticase.

Men comprised approximately 90% of the patients in each study arm, with the mean patient age around 55 years. In both groups, patients had a median of one gout flare in the prior year, and a mean duration of gout of 13 years plus a few months.

The patients’ prior urate-lowering agents included allopurinol and febuxostat, and patients had received colchicine, NSAIDs, and corticosteroids for acute gout.

The mean serum urate levels at baseline were 8.9 mg/dL in the MMF group, and 9.8 mg/dL in the placebo group.

Patients were given either MMF 1 g twice daily or a placebo during a 2-week run-in, with the assigned medications continuing for the first 12 weeks concomitantly with pegloticase. The uricase was given intravenously at a dose of 8 mg every 2 weeks for a total of 12 infusions.

As noted before, 86% of patients in the MMF arm (19 of 22) reached the primary outcome of serum uric acid levels below 6 mg/dL by week 12, compared with 40% (4 of 10) in the placebo arm (P = .01).

Week 24 serum uric acid response, a secondary endpoint, was sustained in 68% of patients in the MMF arm, compared with 30% in the placebo arm (P = .03).

“We found no significant differences between the groups in the absolute change in serum urate from baseline to week 24, or from week 12 to 24. We also did not find any differences between the treatment arms for the PROMIS [Patient Reported Outcomes Measurement Information System] or for the Gout Impact Scale,” Dr. Khanna said.

The most commonly reported adverse events included gout flares in 13% of patients in the MMF group and 3% in the placebo group, cardiac disorders in 3% versus 2%, respectively, and gastrointestinal disorders in 9% versus 2%.

Adverse events that occurred only in the MMF group included infections (3%), musculoskeletal and connective tissue disorders (18%), and respiratory events.

Three patients in the placebo arm had infusion reactions, two of which occurred during the first infusion, and one during the second. One of the reactions was considered serious and required hospitalization, but all infusion reactions resolved and none were fatal. There were no infusion reactions in the MMF arm.

Maybe methotrexate instead?

“The efficacy data for mycophenolate in the RECIPE study are convincing, and suggest that this combination substantially increases the proportion of people who respond to pegloticase,” commented Nicola Dalbeth, MD, professor of medicine at the University of Auckland (New Zealand), who moderated the session where the RECIPE data were reported.

“Previous open-label studies of methotrexate with pegloticase [e.g., the MIRROR study] suggest that methotrexate is another effective option to increase the response to pegloticase. However, at this stage, placebo-controlled trials of methotrexate have not been reported. I think a key consideration will be safety, and which option [methotrexate vs. mycophenolate] is safer, noting that many patients with severe gout have important comorbidities, including chronic kidney disease, diabetes, and liver disease,” she said.

Dr. Bhana also noted that there are multiple factors that might determine the choice of MMF or methotrexate as an immunomodulatory partner for pegloticase.

“Some gout patients have chronic kidney disease or a variety of comorbidities – high uric acid can also cause kidney damage – and if they have a kidney illness, methotrexate may not be a safe medicine because there’s a risk of further toxicity that can lead to bone marrow suppression, which I have seen personally in patients, and in this case mycophenolate would be the preferred option,” he said.

The study was sponsored by the University of Alabama at Birmingham, with collaboration from the University of Michigan, as well as the National Institute of Arthritis and Musculoskeletal and Skin Diseases and Horizon, which makes pegloticase. Dr. Khanna disclosed grant and research support from Dyve, Selecta, and Sobi, and consulting for Sobi and Horizon. Dr. Dalbeth disclosed relationships with AstraZeneca, AbbVie, Arthrosi, Dyve, Selecta, and Janssen. Dr. Bhana disclosed nonbranded consulting work for Horizon.

I think a key consideration will be safety, and which option [methotrexate vs. mycophenolate] is safer, noting that many patients with severe gout have important comorbidities, including chronic kidney disease, diabetes, and liver disease,” she said.

Dr. Bhana also noted that there are multiple factors that might determine the choice of MMF or methotrexate as an immunomodulatory partner for pegloticase.

“Some gout patients have chronic kidney disease or a variety of comorbidities – high uric acid can also cause kidney damage – and if they have a kidney illness, methotrexate may not be a safe medicine because there’s a risk of further toxicity that can lead to bone marrow suppression, which I have seen personally in patients, and in this case mycophenolate would be the preferred option,” he said.

The study was sponsored by the University of Alabama at Birmingham, with collaboration from the University of Michigan, as well as the National Institute of Arthritis and Musculoskeletal and Skin Diseases and Horizon, which makes pegloticase. Dr. Khanna disclosed grant and research support from Dyve, Selecta, and Sobi, and consulting for Sobi and Horizon. Dr. Dalbeth disclosed relationships with AstraZeneca, AbbVie, Arthrosi, Dyve, Selecta, and Janssen. Dr. Bhana disclosed nonbranded consulting work for Horizon.

Timing is everything when it comes to the use of the anabolic agent romosozumab (Evenity) for the treatment of advanced osteoporosis, a review of clinical trials suggests.

In four studies with treatment sequences in which romosozumab was administered either before or following the use of an antiresorptive agent, initial treatment with 1 year of romosozumab produced substantial bone mineral density (BMD) gains in the total hip and lumbar spine.

Transition from romosozumab to a potent resorptive agent, either alendronate or denosumab (Prolia) augmented the initial gains, reported Felicia Cosman, MD, professor of clinical medicine at Columbia University, New York.

Romosozumab was the third approved agent in its class, following teriparatide in 2002, and abaloparatide (Tymlos) in 2017, both of which have been shown to produce rapid reductions in fracture risk and large improvements in BMD when they were administered up front, followed by an antiresorptive agent.

“But since romosozumab has a very different mechanism of action compared to both teriparatide and abaloparatide, we didn’t know if treatment sequence would be as important for this agent as it was for teriparatide,” she said during a press briefing prior to her presentation of the data in an oral abstract session at the virtual annual meeting of the American College of Rheumatology.

Two-for-one

Romosozumab is unique in that it both increases bone formation and decreases bone resorption, and has been shown in treatment-naive postmenopausal women with osteoporosis to significantly improve BMD and reduce fracture risk, compared with either placebo or alendronate. Romosozumab has also been studied as sequential therapy in patients treated initially with either alendronate or denosumab.

To see whether treatment sequence could have differential effects on clinical outcomes for patients with osteoporosis, Dr. Cosman and colleagues looked at results from four clinical trials, using levels of bone turnover markers (procollagen type I N-terminal propeptide [PINP] and beta-isomer of the C-terminal telopeptide of type I collagen [beta-CTX]) and BMD gains in the total hip and spine as outcomes.

The two trials of romosozumab in treatment-naive women were the ARCH trial comparing romosozumab with alendronate in a double-blind phase for 1 year, followed by 1 year of open-label alendronate, and the FRAME trial, in which romosozumab was compared with placebo in a 1-year double-blind phase, followed by 1-year of open-label denosumab.

The two trials of romosozumab in women treated initially with antiresorptive agents were the STRUCTURE trial in which patients on oral bisphosphonates for at least 3 years or alendronate 70 mg weekly for 1 year were randomized to receive either romosozumab or teriparatide, and a phase 2 trial (NCT00896532) that included a 24-month romosozumab or placebo treatment phase followed by rerandomization to a 12-month extension phase with denosumab or placebo, followed by a 12-month retreatment phase with romosozumab, followed by a 24-month follow-on phase with zoledronic acid or no intervention.

Total hip BMD gains

In the ARCH trial, total hip BMD increased 6.2% with 1 year of romosozumab, and a cumulative total of 7.1% with the 2-year romosozumab/alendronate sequence. In the FRAME trial, patients gained 6.8% in total hip BMD after 1 year of romosozumab and a total of 8.8% after 2 years of romosozumab followed by denosumab.

In contrast, in the STRUCTURE trial, patients treated for 1 year or longer with alendronate and then with 1 year of romosozumab had a 2.9% BMD gain in the total hip. In the phase 2 trial, 1 year of romosozumab following 1 year of denosumab yielded a 0.9% BMD gain, for a total gain of 3.8% with the denosumab sequence.
 

Lumbar spine BMD gains

In ARCH, lumbar spine BMD increased 13.7% with 1 year of romosozumab, and a total of 15.2% with the 2-year sequence of romosozumab followed by alendronate. Similarly, in FRAME, patients gained 13.3% in BMD after a year of romosozumab, and total of 17.6% by the end of the 2-year romosozumab/denosumab sequence.

In contrast, in STRUCTURE, patients who had previously been on alendronate for at least 1 year had a gain of 9.8% after 1 year of romosozumab, and in the phase 2 study, patients who had been on denosumab for 1 year had an increase in lumbar spine BMD of 5.3% after 1 year on romosozumab, and a total gain of 11.5% at the end of the 2-year sequence.
 

Serum PINP and beta-CTX

Looking at the markers of bone turnover, the investigators saw that, in both ARCH and FRAME, PINP peaked at over 80% of baseline at 1 month, and then continued to steadily decline past 1 year. The beta-CTX nadir was 40%-50% below baseline at 1 year.

At the end of year 2, the PINP nadir was –67% with follow-on alendronate, and –69% with denosumab, and the beta-CTX nadir was –72% and –92%, respectively.

In the two trials where romosozumab was the follow-on therapy, however, the trends were distinctly different. In STRUCTURE, for example, PINP peaked at 141% of baseline at 1 month, and then returned toward baseline, whereas beta-CTX remained largely unchanged.

In the phase 2 trial, PINP peaked at 28% above baseline at 9 months, and then only slightly declined, and beta-CTX peaked at 211% at the end of 1 year of romosozumab.

Best used up front

“This study is important, because it suggests that for the three bone-building drugs that the best effects will really be attained on bone strength if the agents are used as initial therapy in very-high-risk patients. Those are people who have sustained fractures within the preceding 2 years, who had multiple fractures at any point in their adulthood, and who present with very low BMD, particularly if they have any associated clinical risk factors such as family history or other underlying diseases or medications that have detrimental effects on bone,” Dr. Cosman said at the briefing.

Marcy Bolster, MD, from the division of rheumatology, allergy, and immunology at Massachusetts General Hospital, Boston, and associate professor of medicine at Harvard Medical School in Boston, who was not involved in the study, commented that the study provides important information for clinicians who treat patients with osteoporosis.

“We have an increasing number of medications available for use in the treatment of patients with osteoporosis, and as we consider the importance of reducing fracture risk, the duration of therapy, the timing of a bisphosphonate holiday, it is essential that we consider any advantages to the order or sequence of our medications,” she said when asked for comment.

“This study provides evidence supporting the concept of the ‘anabolic window’ in which there is a demonstrated advantage in treating patients with an anabolic agent prior to treatment with an antiresorptive agent, and while gains in bone mineral density were achieved with either order of medication use, the gains were more dramatic with treatment with romosozumab as the first agent,” she added.

Dr. Bolster also noted it will be important to demonstrate reduction in fracture risk as well as gain in BMD.

The study was sponsored by Amgen, Astellas, and UCB. Dr. Cosman disclosed grants/research support from Amgen, and consulting fees and speaker activities for Amgen and Radius Health. Dr. Bolster disclosed relationships with AbbVie, Corbus, Cumberland, Gilead, Johnson & Johnson, and Pfizer.

Patients who take the vitamin K antagonist warfarin to prevent thromboembolic events are significantly more likely to require knee or hip replacement surgery – a surrogate endpoint for end-stage osteoarthritis – than are patients who take direct oral anticoagulants (DOACs), results of a U.K.-based study showed.

In a nested case-control study, warfarin use was associated with a 1.5-fold risk for knee and hip replacement, compared with use of DOACs.

The findings provide additional evidence for the role of vitamin K and vitamin K–dependent proteins for limiting osteoarthritis progression, said lead author Priyanka Ballal, MD, a rheumatology fellow at Boston University.

“Given the prevalence and impact of osteoarthritis, our data, along with the existing literature, support the need for a well-powered, randomized, controlled trial for evaluating vitamin K supplementation in osteoarthritis. Our study also raises the consideration of using DOACs over warfarin when indicated in people with or at risk of osteoarthritis,“ she said in a plenary session at the virtual annual meeting of the American College of Rheumatology.

Warfarin targets vitamin K for its role in coagulation, but vitamin K is also an essential co-factor for vitamin K-dependent proteins in bone and cartilage, Dr. Ballal said,

Inadequate vitamin K levels are associated with abnormal joint tissue mineralization, and with increased incidence and prevalence of osteoarthritis. In a randomized, controlled trial, vitamin K supplementation was associated with trends toward less osteoarthritis progression among patients with vitamin K deficiency, she said.

To see whether warfarin therapy has biologic effects similar to that seen in patients with vitamin K deficiency, Dr. Ballal and colleagues conducted a nested, case-control study using data from The Health Improvement Network (THIN), an electronic medical record database of patients enrolled with general practitioners in the United Kingdom.

The sample included adults aged 40-80 years with atrial fibrillation who had received one or more prescriptions for warfarin or a DOAC beginning in 2009, a year after DOACs were first marketed in the United Kingdom, and within 1 year of the index date (date of joint replacement surgery). The researchers excluded patients with knee or hip replacements before 2014, severe comorbidities that would limit joint replacement, or who had used either warfarin or a DOAC prior to study entry. Each case was matched by age, gender, and index date with up to four control patients (those who did not have surgery).

A total of 913 cases and 3,652 controls were included. The groups had similar characteristics (sex, age, cancer, renal disease, chronic lung disease, hypertension, and incidence of venous thromboembolism [VTE]), except for somewhat higher rates of diabetes and heart failure among controls, and a higher rate of obesity among cases.

The investigators first looked at warfarin use among all knee and/or hip replacement cases and controls and calculated an odds ratio of 1.57 (95% confidence interval [CI], 1.30-1.89) for knee and hip replacement with warfarin after adjustment for body mass index, factors influencing choice of anticoagulant, comorbidities, other medications, general practitioner visits, and hospitalizations.

The association between warfarin and joint replacement held up in an analysis restricted to knee replacement only, with an adjusted OR of 1.48 (95% CI, 1.16-1.89).

There was also a clear association between duration of warfarin use and risk of knee and hip replacement.

“This abstract suggests the role of adequate vitamin K may be important in decreasing progression of osteoarthritis, which would then favor patients with OA who are on warfarin to consider changing to a DOAC; however, further studies are needed to confirm this finding and consider its impact on VTE and wound healing postop,” said Minna Kohler, MD, director of the rheumatology musculoskeletal ultrasound program at Massachusetts General Hospital in Boston. Dr. Kohler, who was not involved in the study, replied to an email request for comment.

The study was supported by grants from the National Institutes of Health. Dr. Ballal and Dr. Kohler reported having no conflicts of interest to disclose.

Warfarin targets vitamin K for its role in coagulation, but vitamin K is also an essential co-factor for vitamin K-dependent proteins in bone and cartilage, Dr. Ballal said,

Inadequate vitamin K levels are associated with abnormal joint tissue mineralization, and with increased incidence and prevalence of osteoarthritis. In a randomized, controlled trial, vitamin K supplementation was associated with trends toward less osteoarthritis progression among patients with vitamin K deficiency, she said.

To see whether warfarin therapy has biologic effects similar to that seen in patients with vitamin K deficiency, Dr. Ballal and colleagues conducted a nested, case-control study using data from The Health Improvement Network (THIN), an electronic medical record database of patients enrolled with general practitioners in the United Kingdom.

The sample included adults aged 40-80 years with atrial fibrillation who had received one or more prescriptions for warfarin or a DOAC beginning in 2009, a year after DOACs were first marketed in the United Kingdom, and within 1 year of the index date (date of joint replacement surgery). The researchers excluded patients with knee or hip replacements before 2014, severe comorbidities that would limit joint replacement, or who had used either warfarin or a DOAC prior to study entry. Each case was matched by age, gender, and index date with up to four control patients (those who did not have surgery).

A total of 913 cases and 3,652 controls were included. The groups had similar characteristics (sex, age, cancer, renal disease, chronic lung disease, hypertension, and incidence of venous thromboembolism [VTE]), except for somewhat higher rates of diabetes and heart failure among controls, and a higher rate of obesity among cases.

The investigators first looked at warfarin use among all knee and/or hip replacement cases and controls and calculated an odds ratio of 1.57 (95% confidence interval [CI], 1.30-1.89) for knee and hip replacement with warfarin after adjustment for body mass index, factors influencing choice of anticoagulant, comorbidities, other medications, general practitioner visits, and hospitalizations.

The association between warfarin and joint replacement held up in an analysis restricted to knee replacement only, with an adjusted OR of 1.48 (95% CI, 1.16-1.89).

There was also a clear association between duration of warfarin use and risk of knee and hip replacement.

“This abstract suggests the role of adequate vitamin K may be important in decreasing progression of osteoarthritis, which would then favor patients with OA who are on warfarin to consider changing to a DOAC; however, further studies are needed to confirm this finding and consider its impact on VTE and wound healing postop,” said Minna Kohler, MD, director of the rheumatology musculoskeletal ultrasound program at Massachusetts General Hospital in Boston. Dr. Kohler, who was not involved in the study, replied to an email request for comment.

The study was supported by grants from the National Institutes of Health. Dr. Ballal and Dr. Kohler reported having no conflicts of interest to disclose.

Black patients with systemic lupus erythematosus (SLE) are known to have significantly elevated risk for stroke and ischemic heart disease (IHD), compared with non-Black patients with SLE.

Now a team of investigators has identified SLE-specific predictors for major cardiovascular complications in Black patients, pointing to potential prevention strategies in this high-risk population.

Among Black patients in a study of 336 patients with incident SLE, discoid rash at the time of SLE diagnosis predicted a fivefold higher risk for stroke, and renal disorder at the time of diagnosis was associated with a twofold higher risk, compared with non-Black patients, but neither of these symptoms predicted elevated risk of IHD.

In contrast, neurologic disorders, including prior psychosis or seizure, were associated with a fourfold higher risk for IHD, and immunologic disorders including anti-DNA, anti-Smith, or antiphospholipid antibodies were associated with a nearly fivefold greater risk for IHD in Black patients, but neither of these comorbidities predicted strokes, reported Shivani Garg, MD, assistant professor of medicine at the University of Wisconsin in Madison.

“Our study was one of the first to highlight racial disparities in CVD subtypes, with a threefold higher stroke risk and 24-fold higher ischemic heart disease risk in Black patients with lupus. Compared to previous studies in Black populations, our study highlights different peak timing of early stroke and ischemic heart disease in our cohort,“ she said at a plenary session during the virtual annual meeting of the American College of Rheumatology.

The study is one of the first to identify specific and unique SLE disease-related predictors of stroke and ischemic heart disease, she said.

Georgia Lupus Registry data

Dr. Garg and colleagues at the University of Wisconsin and Emory University in Atlanta drew on data from the Georgia Lupus Registry, a population-based registry of SLE patients from the Atlanta area. They identified patients diagnosed from 2002 through 2004 who had four or more ACR criteria for SLE, or three or more criteria plus a final diagnosis of SLE made by their board-certified rheumatologists.

The patients were matched to the Georgia Hospital Discharge Database and National Death Index from 2000 through 2013, with stroke- and IHD-related hospitalizations and deaths classified by the first three admission codes or cause-of-death codes.

Patients with transient ischemic attacks were included in the stroke category, and those with myocardial infarction and angina were included in the IHD category.

They identified 336 patients, 87% of whom were female, and 75% of whom were Black. The mean age at SLE diagnosis was 40 years. Among this cohort, there were 38 stroke-related events or deaths and 25 IHD-related events or deaths recorded from the period 2 years before through 14 years after an SLE diagnosis.
 

Early stroke, late IHD

The investigators first looked at the timing of stroke vs. IHD and found that a disproportionately high percentage of stroke events occurred in the second year after SLE diagnosis, whereas the peak of IHD-related events occurred in the 14^th year after diagnosis.

They then performed a race-stratified Cox proportional hazard analysis, and found a threefold higher risk for stroke in Black patients versus non-Black patients (P = .007) and a 24-fold higher risk for IHD (P < .0001).

In multivariate analysis, significant predictors of stroke were Black race with a hazard ratio (HR) of 3.4 (P = .028), discoid rash (HR, 4.6; P = .0028), and renal disorder (HR, 2.4; P = .04). However, stroke was not predicted by age, sex, immunologic disorder, serositis, hematologic disorder, or ACR criteria total greater than four.

Significant predictors of IHD included age 65 and older (HR, 61; P = .0007), Black race (HR, 24; P = .004), neurologic disorder (HR, 4.0; P = .018), and immunologic disorder (HR, 4.7; P = .02). But IHD could not be predicted by oral ulcers, discoid rash, or ACR criteria more than four.

“In future studies, we will examine mechanisms that drive the different timing and predictors of CVD subtypes and disparities. We will also examine the impact of timely prevention in high-risk SLE subsets,” Dr. Garg said.
 

Managing CVD risk

Angus Worthing, MD, from Arthritis & Rheumatism Associates in Chevy Chase, Md., and Washington, D.C., who moderated a press briefing where Dr. Garg discussed her data, routinely treats patients of different racial backgrounds with lupus. When asked how he manages patients with SLE and suspected cardiovascular complications, Dr. Worthing said, “I tend to, in my practice – and these kinds of studies may change what I do – watch for symptoms that might reflect coronary artery disease or cerebrovascular disease, potentially looking at the smaller arteries in the hands and feet as clues, and I will refer promptly to a vascular surgery expert or cardiologist for screening,” he said.

Dr. Garg added that in her practice, she and colleagues treat high-risk subsets of patients, such as those with lupus nephritis or multiple comorbidities, with aggressive blood pressure control and monitoring, as well as smoking cessation recommendations and lipid monitoring. They also try to limit or, if possible, decrease steroid doses to reduce risk for cardiovascular side effects.

Support for the study came in part from the U.S. Centers for Disease Control and Prevention. Dr. Garg and Dr. Worthing reported having no relevant disclosures.

The age of antiretroviral therapy (ART) for HIV is in its third decade, and many of the patients who live in areas of the world fortunate enough to have had early access to therapy have now lived for several decades with complications of HIV and viral suppressive therapy.

But while the life-expectancy of persons with HIV has approached that of noninfected persons over the last 20 years, the higher burden of comorbidities for aging patients with HIV has remained largely the same, according to an epidemiologist who specializes in HIV/AIDS research and aging.

“The pathways from HIV and its treatments to comorbidities are very long and winding, spanning a life course. Social determinants of health and individual risk factors also play an important role, and must be considered,” said Keri N. Althoff, PhD, MPH, of Johns Hopkins University, Baltimore.

Dr. Althoff discussed long-term complications of HIV and its treatment in a virtual symposium during an annual scientific meeting on infectious diseases.

“Many urban HIV providers have an increased proportion of patients who are older long-term survivors of the epidemic. Many, but not all of the comorbidities (including cardiovascular, neurocognitive, renal, and malignancies) have been associated with age, long-term HIV infection, especially uncontrolled HIV infection, and low CD4 nadirs,” commented Harry Lampiris, MD, professor of clinical medicine at the University of California, San Francisco.

“An increasing number of patients are experiencing geriatric syndromes (especially problems with mobility, cognitive decline, food insecurity, polypharmacy, and social isolation) at younger ages than HIV-negative populations,” he added.

Dr. Lampiris, who moderated the session where Dr. Althoff presented her findings, commented on it in an interview, but was not involved in her research.
 

Pathways to comorbidity

The three primary pathways to comorbidities in people with HIV infections are as follows, according to Dr. Athloff:

• The virus itself, with its associated inflammation, immunosuppression, immune activation, and AIDS.
• HIV therapies, beginning with the notoriously toxic dideoxynucleoside analogues or “d-drugs,” and following with subsequent generations of newer, less toxic agents.
• Individual risk factors, including smoking, stress, diet, exercise, and environment.

Cardiovascular and renal complications

Persons with HIV have an approximately twofold higher risk for major adverse cardiovascular events (myocardial infarction, stroke) compared with persons without HIV. Conditions contributing to cardiovascular disease including hypertension, diabetes, and hyperlipidemia are also significantly higher among persons with HIV, Dr. Althoff said.

Hypertension among persons with HIV from the ages 60-69 years is especially high for Black men and to a lesser degree non-Black men, compared with either White or Black women, she noted.

Pathways to renal disease in persons with HIV include diabetes and hypertension, as well as therapies to treat them, hepatitis B and C coinfection, HIV-associated nephropathy, and immune complex kidney disease, as well as chronic kidney disease resulting from acute kidney injury related to therapy.

“Cardiovascular disease and kidney disease are excellent examples of why the life-course perspective is essential when caring for people with HIV. For those diagnosed with HIV at younger ages, there are points of intervention along the decades-long path, and the timing and implementation of the most effective intervention may preserve comorbidity-free years,” Dr. Althoff said.

Prevention and screening interventions to lower risk for future heart- and kidney-related comorbidities include smoking cessation and lifestyle optimization (diet, exercise, mental health), as well as lipid-lowering medications to lower risk for cardiovascular events.
 

Liver comorbidities

“Primary drivers of liver disease are social determinants of health and individual lifestyle risk factors that share the same pathways as HIV, resulting in this increased burden of liver disease in people with HIV,” she said.

Risk factors include alcoholic liver disease, nonalcoholic fatty liver disease, hepatitis B and C coinfection, drug use, autoimmune disease, and aging. These risk factors contribute to oxidative stress, mitochondrial injury, lipotoxicity, cytotoxicity, and other mechanisms that can lead to fibrosis, cirrhosis, hepatocellular carcinoma, and end-stage liver disease.

“I want to be sure to acknowledge the importance of liver disease as a comorbidity among people with HIV. Liver disease accounts for nearly 20% of mortality in persons with HIV,” she said.
 

Neurocognitive problems

HIV has been linked to neurocognitive decline since the beginning of the epidemic, Dr. Althoff noted. The term HIV-associated neurocognitive disorders encompasses the broad spectrum of cognitive effects of HIV, from asymptomatic illness to AIDS-related dementia. Estimates of cognitive impairment in people with HIV range from 14% to 64% across various study populations, but diagnosing and treating it in the community can be challenging.

“Routine monitoring of cognition is often just out of reach in the clinical setting, due to the time it takes to use validated tools. We need a deeper toolbox of quick and validated tools calibrated to people with HIV in order to accurately monitor cognition,” she said.

She noted that the average age of onset of Alzheimer’s disease in the general population is 80 years, and that relatively few people with HIV infection have reached that age.

“But before the population age distribution shifts to the older ages, we can do more to monitor cognition in people with HIV,” she added.

In addition to HIV, factors that can contribute to worse neurocognitive outcomes include major depressive disorder, occurring in and estimated 20%-40% of adults with HIV versus 8% of the U.S. population, generalized anxiety disorder (10%-25% vs. 3%), bipolar disorder (3%-9% vs. 3%), schizophrenia (4%-15% vs. 1%), and posttraumatic stress disorder (10%-30% vs. 8%).

Substance use and polypharmacy, common among adults with HIV, can also contribute to cognitive decline, she said.
 

Decreased mobility

The Multicenter AIDS Cohort Study (MACS) showed that decreased mobility, defined as a gait speed less than 1 m/sec, occurred earlier in life among HIV-positive men than in HIV-negative men.

In the general aging population, slow gait speed is a predictor for lower extremity limitations, hospitalization, and death, and in more recent MACS studies was associated with increased hemoglobin A_1C levels, as well as neurocognitive impairment.

“Hemoglobin A_1C is an intervenable target, and perhaps it will help to slow the decline in gait speed,” Dr. Althoff said.
 

Reduce ‘healthspan’ disparities

The goal for treating aging adults with HIV “is to reduce the disparity in healthspan between people with HIV compared to people without HIV by delaying or eliminating the onset of comorbidities among people with HIV,” she said.

The gerontological concept of extending “healthspan” – the duration of life without significant comorbidities – is to target common mechanisms of aging, thereby delaying the onset of more than one age-related disease at the same time.

“Crude translation of this concept to the population of aging with HIV includes reducing that gap in comorbidity-free survival in people with versus without HIV,” she said.

Modification of care models from geriatrics may help infectious disease specialists manage adults with HIV who have increasingly complex needs.

For example, the geriatric “5 M” model emphasizes focusing on issues of mind (mentation, dementia, delirium, depression), mobility (impaired gait and balance, as well as fall prevention), medications (reducing polypharmacy, optimal prescribing), multicomplexity (multiple morbidities and complex bio-psycho-social situations), and “matters most” (each patient’s individual meaningful health outcome goals and care preferences).

Changing exposures that may influence the pattern of comorbidities for patients with HIV in the future include earlier start on ART, shorter duration of uncontrolled viremia, compared with older populations, newer and less toxic ARTs, long-term viral suppression, and risk factor interventions, Dr. Althoff concluded.

Dr. Lampiris noted that “patients who have initiated therapy in the last 5-10 years are more likely to initiate antiretroviral therapy at higher CD4 counts, and less likely to experience long-term toxicities of antiretroviral therapy. However, African Americans, Hispanics and HIV-positive women continue to lag behind others with regard to timely initiation of treatment.

“In addition there are toxicities associated with the newer agents, particularly weight gain, which disproportionately affect African Americans and women and which may be made worse by poverty, food insecurity, and other health-related behaviors.”

Dr. Athloff’s work is supported by grants from the National Institutes for Health. She disclosed serving as a consultant to the NIH-funded All of US study and to MediQ, and as an adviser to TrioHealth. Dr. Lampiris reported having no disclosures.

For example, the geriatric “5 M” model emphasizes focusing on issues of mind (mentation, dementia, delirium, depression), mobility (impaired gait and balance, as well as fall prevention), medications (reducing polypharmacy, optimal prescribing), multicomplexity (multiple morbidities and complex bio-psycho-social situations), and “matters most” (each patient’s individual meaningful health outcome goals and care preferences).

Changing exposures that may influence the pattern of comorbidities for patients with HIV in the future include earlier start on ART, shorter duration of uncontrolled viremia, compared with older populations, newer and less toxic ARTs, long-term viral suppression, and risk factor interventions, Dr. Althoff concluded.

Dr. Lampiris noted that “patients who have initiated therapy in the last 5-10 years are more likely to initiate antiretroviral therapy at higher CD4 counts, and less likely to experience long-term toxicities of antiretroviral therapy. However, African Americans, Hispanics and HIV-positive women continue to lag behind others with regard to timely initiation of treatment.

“In addition there are toxicities associated with the newer agents, particularly weight gain, which disproportionately affect African Americans and women and which may be made worse by poverty, food insecurity, and other health-related behaviors.”

The age of antiretroviral therapy (ART) for HIV is in its third decade, and many of the patients who live in areas of the world fortunate enough to have had early access to therapy have now lived for several decades with complications of HIV and viral suppressive therapy.

But while the life-expectancy of persons with HIV has approached that of noninfected persons over the last 20 years, the higher burden of comorbidities for aging patients with HIV has remained largely the same, according to an epidemiologist who specializes in HIV/AIDS research and aging.

“The pathways from HIV and its treatments to comorbidities are very long and winding, spanning a life course. Social determinants of health and individual risk factors also play an important role, and must be considered,” said Keri N. Althoff, PhD, MPH, of Johns Hopkins University, Baltimore.

Dr. Althoff discussed long-term complications of HIV and its treatment in a virtual symposium during an annual scientific meeting on infectious diseases.

“Many urban HIV providers have an increased proportion of patients who are older long-term survivors of the epidemic. Many, but not all of the comorbidities (including cardiovascular, neurocognitive, renal, and malignancies) have been associated with age, long-term HIV infection, especially uncontrolled HIV infection, and low CD4 nadirs,” commented Harry Lampiris, MD, professor of clinical medicine at the University of California, San Francisco.

“An increasing number of patients are experiencing geriatric syndromes (especially problems with mobility, cognitive decline, food insecurity, polypharmacy, and social isolation) at younger ages than HIV-negative populations,” he added.

Dr. Lampiris, who moderated the session where Dr. Althoff presented her findings, commented on it in an interview, but was not involved in her research.
 

Pathways to comorbidity

The three primary pathways to comorbidities in people with HIV infections are as follows, according to Dr. Athloff:

• The virus itself, with its associated inflammation, immunosuppression, immune activation, and AIDS.
• HIV therapies, beginning with the notoriously toxic dideoxynucleoside analogues or “d-drugs,” and following with subsequent generations of newer, less toxic agents.
• Individual risk factors, including smoking, stress, diet, exercise, and environment.

Cardiovascular and renal complications

Persons with HIV have an approximately twofold higher risk for major adverse cardiovascular events (myocardial infarction, stroke) compared with persons without HIV. Conditions contributing to cardiovascular disease including hypertension, diabetes, and hyperlipidemia are also significantly higher among persons with HIV, Dr. Althoff said.

Hypertension among persons with HIV from the ages 60-69 years is especially high for Black men and to a lesser degree non-Black men, compared with either White or Black women, she noted.

Pathways to renal disease in persons with HIV include diabetes and hypertension, as well as therapies to treat them, hepatitis B and C coinfection, HIV-associated nephropathy, and immune complex kidney disease, as well as chronic kidney disease resulting from acute kidney injury related to therapy.

“Cardiovascular disease and kidney disease are excellent examples of why the life-course perspective is essential when caring for people with HIV. For those diagnosed with HIV at younger ages, there are points of intervention along the decades-long path, and the timing and implementation of the most effective intervention may preserve comorbidity-free years,” Dr. Althoff said.

Prevention and screening interventions to lower risk for future heart- and kidney-related comorbidities include smoking cessation and lifestyle optimization (diet, exercise, mental health), as well as lipid-lowering medications to lower risk for cardiovascular events.
 

Liver comorbidities

“Primary drivers of liver disease are social determinants of health and individual lifestyle risk factors that share the same pathways as HIV, resulting in this increased burden of liver disease in people with HIV,” she said.

Risk factors include alcoholic liver disease, nonalcoholic fatty liver disease, hepatitis B and C coinfection, drug use, autoimmune disease, and aging. These risk factors contribute to oxidative stress, mitochondrial injury, lipotoxicity, cytotoxicity, and other mechanisms that can lead to fibrosis, cirrhosis, hepatocellular carcinoma, and end-stage liver disease.

“I want to be sure to acknowledge the importance of liver disease as a comorbidity among people with HIV. Liver disease accounts for nearly 20% of mortality in persons with HIV,” she said.
 

Neurocognitive problems

HIV has been linked to neurocognitive decline since the beginning of the epidemic, Dr. Althoff noted. The term HIV-associated neurocognitive disorders encompasses the broad spectrum of cognitive effects of HIV, from asymptomatic illness to AIDS-related dementia. Estimates of cognitive impairment in people with HIV range from 14% to 64% across various study populations, but diagnosing and treating it in the community can be challenging.

“Routine monitoring of cognition is often just out of reach in the clinical setting, due to the time it takes to use validated tools. We need a deeper toolbox of quick and validated tools calibrated to people with HIV in order to accurately monitor cognition,” she said.

She noted that the average age of onset of Alzheimer’s disease in the general population is 80 years, and that relatively few people with HIV infection have reached that age.

“But before the population age distribution shifts to the older ages, we can do more to monitor cognition in people with HIV,” she added.

In addition to HIV, factors that can contribute to worse neurocognitive outcomes include major depressive disorder, occurring in and estimated 20%-40% of adults with HIV versus 8% of the U.S. population, generalized anxiety disorder (10%-25% vs. 3%), bipolar disorder (3%-9% vs. 3%), schizophrenia (4%-15% vs. 1%), and posttraumatic stress disorder (10%-30% vs. 8%).

Substance use and polypharmacy, common among adults with HIV, can also contribute to cognitive decline, she said.
 

Decreased mobility

The Multicenter AIDS Cohort Study (MACS) showed that decreased mobility, defined as a gait speed less than 1 m/sec, occurred earlier in life among HIV-positive men than in HIV-negative men.

In the general aging population, slow gait speed is a predictor for lower extremity limitations, hospitalization, and death, and in more recent MACS studies was associated with increased hemoglobin A_1C levels, as well as neurocognitive impairment.

“Hemoglobin A_1C is an intervenable target, and perhaps it will help to slow the decline in gait speed,” Dr. Althoff said.
 

Reduce ‘healthspan’ disparities

The goal for treating aging adults with HIV “is to reduce the disparity in healthspan between people with HIV compared to people without HIV by delaying or eliminating the onset of comorbidities among people with HIV,” she said.

The gerontological concept of extending “healthspan” – the duration of life without significant comorbidities – is to target common mechanisms of aging, thereby delaying the onset of more than one age-related disease at the same time.

“Crude translation of this concept to the population of aging with HIV includes reducing that gap in comorbidity-free survival in people with versus without HIV,” she said.

Modification of care models from geriatrics may help infectious disease specialists manage adults with HIV who have increasingly complex needs.

For example, the geriatric “5 M” model emphasizes focusing on issues of mind (mentation, dementia, delirium, depression), mobility (impaired gait and balance, as well as fall prevention), medications (reducing polypharmacy, optimal prescribing), multicomplexity (multiple morbidities and complex bio-psycho-social situations), and “matters most” (each patient’s individual meaningful health outcome goals and care preferences).
