Lupus & Connective Tissue Diseases

Low-dose aspirin may be considered for the primary prevention of cardiovascular disease (CVD) in patients with autoimmune systemic rheumatic diseases who are at particularly high risk because of their individual cardiovascular risk profile, according to authors of a new review article in the journal Rheumatology who acknowledge the controversial nature of the issue, because while significant cardiovascular benefit from aspirin for secondary prevention is well established, it has not been for primary prevention.

Secondary prevention with daily, low-dose aspirin is part of aggressive, comprehensive risk modification in patients who have experienced an MI or stroke or are considered at high risk for CVD. But when it comes to primary prevention of the onset of disease, the authors, led by Serena Fasano, MD, PhD, of the rheumatology unit at the University of Campania, Naples, Italy, acknowledged the contradictory positions of international guidelines and uncertainty over balancing benefit versus harm – including risk of mortality in the context of excess bleeding. They called for “robust data” from high-quality randomized, controlled trials for subgroups of patients with specific rheumatologic diseases in order to better answer the question of aspirin for primary prevention.

“This review is devoted to reporting the present knowledge on the effectiveness of low-dose [aspirin] in primary CV prevention in a number of autoimmune systemic rheumatic diseases, not a systematic review or meta-analysis,” the authors stated. “We are not claiming to have covered more than a selection of the literature for each disease. Available data are not high-quality data and do not provide firm conclusions.”

The authors focused primarily on accelerated, rather than spontaneous, atherosclerosis or buildup of plaque in artery walls, implicated in ischemic heart diseases such as MI and ischemic cerebrovascular diseases such as stroke. They looked at its association with autoimmune rheumatic diseases, primarily systemic lupus erythematosus (SLE) and RA, but also including antiphospholipid syndrome, systemic sclerosis, mixed connective tissue disease, dermatomyositis/polymyositis, primary Sjögren’s syndrome, and systemic vasculitis.

They shared results from a review of 167 patients with SLE consecutively admitted to their tertiary medical center who had not previously experienced a cardiovascular event and who were prescribed low-dose (100 mg) aspirin on their first visit and followed for 8 years. The cardiovascular event-free rate was higher in the aspirin group and no excess bleeding was noted, although this may be attributable to a younger patient population and routine use of proton pump inhibitors. Subsequently, hydroxychloroquine was added to the aspirin treatment and was associated with further reduction in cardiovascular events.

The research group also conducted a retrospective analysis of 746 patients with RA consecutively admitted to four tertiary medical centers who hadn’t experienced a cardiovascular event previously. Incidence of cardiovascular events was significantly lower in aspirin-treated patients.

There may be a modest benefit of using low-dose aspirin on a long-term basis, but that benefit needs to be offset by the risk of bleeds, said M. Elaine Husni, MD, MPH, vice chair of rheumatology and director of the Arthritis and Musculoskeletal Center at the Cleveland Clinic. It’s important to remind clinicians of cardiovascular risk, she said. “But the message for rheumatologists is it needs to be prescribed on an individual basis, rather than based on diagnosis of a rheumatic condition – at least until we have better evidence.”

Dr. Husni recommended keeping an open mind regarding individual approaches – for example, low-dose aspirin plus statins. A composite approach to prevention likely is called for, including attention to lifestyle issues such as smoking cessation, exercise, and weight loss. “That kind of complexity in decision-making highlights the need for comanagement with a cardiologist,” she said. “I’m a big believer in comanagement. At my multidisciplinary medical center, I am able to pick up the phone and talk to a cardiologist with whom our group has a relationship.” If physicians don’t have that kind of relationship with a cardiology group, she suggested reaching out to establish one.

The review paper could give some guidance to rheumatologists for use on an individual case, Michael Nurmohamed, MD, PhD, of the Amsterdam Rheumatology and Immunology Center in the Netherlands commented in an interview. “However, firm recommendations cannot be given as proper investigations are still lacking, as acknowledged by the authors. In addition, the review paper itself has some methodological constraints. Although this is a narrative review, the search strategy should have been specified, and a quality assessment of the individual studies is lacking.”

There is no doubt that the CVD burden in RA and other rheumatologic conditions is substantially increased in comparison to the general population, Dr. Nurmohamed said. That has been assessed by several well-designed, prospective, controlled studies. Other relatively frequent inflammatory arthropathies, including ankylosing spondylitis and psoriatic arthritis, also pose cardiovascular risk.

“Aspirin cannot be recommended for primary CVD prevention in inflammatory arthropathies due to the absence of adequate studies. That’s why the EULAR [European League Against Rheumatism] guidelines did not recommend its use,” he said. Currently, a EULAR task force is developing evidence-based guidelines for primary CVD prevention in the diseases discussed by Fasano et al., where the use of aspirin will be reassessed. “As these guidelines will consider the methodological quality of the underlying studies, they will enable a more refined use of aspirin in daily clinical practice.”

Primary prevention of CVD using aspirin is not currently the standard of care in taking care of patients with rheumatologic disease in the Netherlands, Ronald F. van Vollenhoven, MD, PhD, Dr. Nurmohamed’s colleague and director of the Amsterdam Rheumatology and Immunology Center and the chair of the department of rheumatology and clinical immunology at the Amsterdam University Medical Center, said in an interview.

“One reason may be the limited data, as highlighted in the review by Dr. Fasano and colleagues. However, another consideration is the problem of polypharmacy. Rheumatic diseases usually require chronic treatment, sometimes with multiple medications. This makes it even more of a concern to add an additional medication, even a relatively innocuous one such as low-dose aspirin,” he said.

Dr. Husni, Dr. Nurmohamed, and Dr. van Vollenhoven reported having no relevant disclosures. The authors of the review article had no relevant disclosures.

Systemic lupus erythematosus remains a treatment challenge, but a variety of drugs in the pipeline are set to target type I interferons, cytokines, and B cells, according to Richard Furie, MD, chief of the division of rheumatology at Northwell Health and professor of medicine at Hofstra University, Hempstead, N.Y.

In general, when treating patients with systemic lupus erythematosus (SLE), “we just don’t see satisfactory response rates,” Dr. Furie said in an online presentation at the annual Perspectives in Rheumatic Diseases held by Global Academy for Medical Education.

“I think the greatest unmet need is in lupus nephritis,” he said. The data show that not even one-third of patients are adequately responding to standard of care treatment. “We need to do better in lupus nephritis but also for those patients with moderate-severe manifestations outside the kidney.”

Patients with SLE have elevated levels of interferon-alpha, Dr. Furie noted. Data from recent studies show that interferon inhibitors can reduce clinical activity in SLE patients, he said.

“About two-thirds to three-quarters of lupus patients have evidence of interferon pathway activation,” he said. There are three types of interferons, and five subtypes of type I interferon, and all five subtypes of type I interferon bind to the same receptor, which is an important strategy for drug development.

In particular, recent phase 2 and 3 trials have focused on targeting type I interferons with anifrolumab, which blocks all five subtypes.

Dr. Furie cited “very robust results” from a phase 2 study. Results of two phase 3 trials of anifrolumab led to a split decision, but the totality of the data collected across the phase 2 and 3 studies points to a drug that is effective for patients with SLE. The two phase 3 studies were published in Lancet Rheumatology and the New England Journal of Medicine.

Dr. Furie also identified recent studies of baricitinib (Olumiant), which has the ability to target several different cytokines. A phase 2 study in 2018 showed a significant difference in SLE Responder Index between lupus patients who received 4 mg of baricitinib or placebo, and a phase 3 study is underway, he said.

For lupus nephritis, Dr. Furie cited the BLISS-LN trial, a 104-week, randomized trial of patients with active lupus nephritis. The group of patients who received belimumab (Benlysta), a monoclonal antibody that targets B-cell activating factor, in addition to standard therapy had significant improvements in renal responses, compared with standard therapy alone (43.0% vs. 32.3%). The outcome measure was Primary Efficacy Renal Response, defined as urinary protein/creatinine ratio <0.7, eGFR ≥60 mL/min per 1.73 m², confirmation on consecutive visits, and required tapering of background glucocorticoids.

Although belimumab was approved for SLE in 2011, the BLISS-LN study focused on SLE patients with active kidney disease. “Neutralizing B-cell activating factor and down-regulating autoreactive B-cell function in kidneys represented a compelling therapeutic approach to lupus nephritis,” he explained.

Voclosporin, distinct from cyclosporine, has also been studied in lupus nephritis, Dr. Furie said. Voclosporin offers several benefits over cyclosporine, including greater potency and a lower drug and metabolite load, as well as a more consistent pharmacokinetic and pharmacodynamic relationship, he said. In the phase 3 AURORA study, presented at this year’s EULAR congress, 40% of patients with lupus nephritis met the primary endpoint of a renal response at 52 weeks, compared with 22.5% of placebo patients.

Looking ahead to the treatment of SLE in 2021, “I feel very strongly that voclosporin will be approved for lupus nephritis,” he said. He also predicted that the use of belimumab will be officially extended for lupus nephritis and that anifrolumab will receive an approval for SLE patients.

In addition, the future may witness the increased use of biomarkers and development of more individualized therapy. These breakthroughs will yield better outcomes for all lupus patients, he said.

A new study has found that late-onset neutropenia is a notably common and occasionally serious occurrence in rituximab-treated patients with autoimmune diseases.

“The literature on late-onset neutropenia – or LON – has, to date, been limited in size and scope,” first author Reza Zonozi, MD, of Massachusetts General Hospital in Boston, said in an interview. “At the Vasculitis and Glomerulonephritis Center at Mass General, we’ve seen a number of cases of LON. Even though most are incidental and can be self-limiting, some can be severe and associated with sepsis. As such, we’ve come to appreciate it as one of the more concerning side effects of rituximab.

“Our hope was to offer a practical analysis of LON, how often it happens, and what it looks like,” he added, “as well as to share our approach to its management.” Their findings were published in Arthritis & Rheumatology.

To investigate the incidence, clinical features and outcomes of LON, the researchers launched a study of 738 adult patients with autoimmune diseases who were being treated with rituximab-induced continuous B-cell depletion. For the purposes of this study, LON was defined as an unexplained absolute neutrophil count of less than 1,000 cells/mcL during the period of B-cell depletion. Regarding disease type, 529 of the patients had antineutrophil cytoplasmic antibody–associated vasculitis (AAV), 73 had membranous nephropathy (MN), 59 had minimal change disease or focal segmental glomerulosclerosis (MCD/FSGS), 24 had lupus nephritis, and 53 had another autoimmune disease. Their average age was 58, and 53% were female.

All patients received a median of eight doses of rituximab – most commonly administered as one 1,000-mg IV dose every 4-6 months – and were in a state of B-cell depletion for a median of 2.5 years. Two months of low-dose daily oral cyclophosphamide was also used concurrently in 70% (n = 515) of patients. Glucocorticoids were used in 95% (n = 698) of patients.

During follow-up, 107 episodes of LON occurred in 71 patients. At 1, 2, and 5 years of continuous B-cell depletion, the incidence of LON was 6.6% (95% confidence interval, 5.0%-8.7%), 7.9% (95% CI, 6.1%-10.2%), and 13.5% (95% CI, 10.4%-17.4%), respectively. The first year following treatment initiation saw a much higher incidence rate of 7.2 per 100 person-years (95% CI, 5.4-9.6), compared with the rate thereafter of 1.5 per 100 person-years (95% CI, 1.0-2.3). LON occurred at a median of 4.1 months (interquartile range, 1.6-23.1) after the first rituximab infusion. The most common treatment for a LON episode was filgrastim.

Of the 107 episodes, 63 (59%) were asymptomatic. No infections were identified in asymptomatic episodes, while infections were identified in all symptomatic episodes. The most common symptom was a fever, and all 30 patients with LON and fever were hospitalized for management of febrile neutropenia. Four of the episodes included gingival soreness, and eight were complicated by sepsis. All the sepsis cases were resolved with standard therapy. One patient died with multiple relapsing LON.

Of the 71 patients with LON, 9 were not rechallenged with rituximab. A total of four of those patients had second LON episodes. Of the 62 patients who were rechallenged, 13 had second LON episodes over a median follow-up period of 2.4 years. The cumulative incidence of recurrent LON at 1, 2, and 5 years after rechallenge was 11.5% (95% CI, 5.6%-22.6%), 23.4% (95% CI, 13.8%-38.2%), and 30.4% (95% CI, 16.9%-50.9%), respectively.

Percentagewise, LON occurred significantly more often in patients with lupus nephritis (25%) than in patients with AAV (10.4%), MN (8.2%), or other diseases (7.6%) (P = .03). LON did not occur in any of the patients with MCD/FSGS. After multivariable analysis, lupus nephritis was associated with higher odds of developing LON (adjusted hazard ratio, 2.96; 95% CI, 1.10-8.01). A multivariable model also found that patients treated with cyclophosphamide and rituximab had higher odds of developing LON, compared with patients who did not receive cyclophosphamide (aHR, 1.98; 95% CI, 1.06-3.71).

 

Still more to learn about what leads to LON

“In large part, these findings quantify what our experience has been with LON in clinical practice,” Dr. Zonozi said. “It is indeed common, it’s often incidental, and most cases are reversible and respond well to treatment. But it can be associated with severe infections, including sepsis, and warrants close monitoring.”

In an interview, Md Yuzaiful Md Yusof, MBChB, PhD, observed that this incidence rate was notably higher than what he’d seen previously. Dr. Md Yusof presented at EULAR Congress 2015 on rituximab and LON, finding that 23 patients (2.5%) from a cohort of 912 developed rituximab-associated neutropenia.

“Most of our cases were in patients with rheumatoid arthritis,” he added, “so it may just be a difference in cohorts.”

Regardless, he applauded additional research in this area, noting that “the etiology of rituximab-associated LON is still unclear. The reasons behind this occurrence need investigating, particularly in regard to severe neutropenia cases. If we can find the predictors of those, it will be extremely helpful for the future of treatment.”

Dr. Zonozi agreed that “more investigation is needed to accurately define the mechanism of LON, which remains unknown. This will likely lead to more targeted strategies to both prevent and treat it.”

The authors acknowledged their study’s limitations, including being a single-center study that relied on retrospective data collection. They also acknowledged that, because the center is a nephrology-based practice, there was a low number of certain diseases like RA, opening up the possibility that “rates of LON are different” in those patients.

Two authors’ work on the study was funded by grants from the National Institutes of Health. The authors disclosed no potential conflicts of interest.

A new study has found that late-onset neutropenia is a notably common and occasionally serious occurrence in rituximab-treated patients with autoimmune diseases.

“The literature on late-onset neutropenia – or LON – has, to date, been limited in size and scope,” first author Reza Zonozi, MD, of Massachusetts General Hospital in Boston, said in an interview. “At the Vasculitis and Glomerulonephritis Center at Mass General, we’ve seen a number of cases of LON. Even though most are incidental and can be self-limiting, some can be severe and associated with sepsis. As such, we’ve come to appreciate it as one of the more concerning side effects of rituximab.

“Our hope was to offer a practical analysis of LON, how often it happens, and what it looks like,” he added, “as well as to share our approach to its management.” Their findings were published in Arthritis & Rheumatology.

To investigate the incidence, clinical features and outcomes of LON, the researchers launched a study of 738 adult patients with autoimmune diseases who were being treated with rituximab-induced continuous B-cell depletion. For the purposes of this study, LON was defined as an unexplained absolute neutrophil count of less than 1,000 cells/mcL during the period of B-cell depletion. Regarding disease type, 529 of the patients had antineutrophil cytoplasmic antibody–associated vasculitis (AAV), 73 had membranous nephropathy (MN), 59 had minimal change disease or focal segmental glomerulosclerosis (MCD/FSGS), 24 had lupus nephritis, and 53 had another autoimmune disease. Their average age was 58, and 53% were female.

All patients received a median of eight doses of rituximab – most commonly administered as one 1,000-mg IV dose every 4-6 months – and were in a state of B-cell depletion for a median of 2.5 years. Two months of low-dose daily oral cyclophosphamide was also used concurrently in 70% (n = 515) of patients. Glucocorticoids were used in 95% (n = 698) of patients.

During follow-up, 107 episodes of LON occurred in 71 patients. At 1, 2, and 5 years of continuous B-cell depletion, the incidence of LON was 6.6% (95% confidence interval, 5.0%-8.7%), 7.9% (95% CI, 6.1%-10.2%), and 13.5% (95% CI, 10.4%-17.4%), respectively. The first year following treatment initiation saw a much higher incidence rate of 7.2 per 100 person-years (95% CI, 5.4-9.6), compared with the rate thereafter of 1.5 per 100 person-years (95% CI, 1.0-2.3). LON occurred at a median of 4.1 months (interquartile range, 1.6-23.1) after the first rituximab infusion. The most common treatment for a LON episode was filgrastim.

Of the 107 episodes, 63 (59%) were asymptomatic. No infections were identified in asymptomatic episodes, while infections were identified in all symptomatic episodes. The most common symptom was a fever, and all 30 patients with LON and fever were hospitalized for management of febrile neutropenia. Four of the episodes included gingival soreness, and eight were complicated by sepsis. All the sepsis cases were resolved with standard therapy. One patient died with multiple relapsing LON.

Of the 71 patients with LON, 9 were not rechallenged with rituximab. A total of four of those patients had second LON episodes. Of the 62 patients who were rechallenged, 13 had second LON episodes over a median follow-up period of 2.4 years.

A nurse-led intervention aimed at reducing hospital readmission rates for systemic lupus erythematosus (SLE) is feasible but the jury is out as to whether it can achieve its primary goal, a study has found.

Copyright Kimberly Pack/Thinkstock

A paper published in Arthritis Care & Research presents the outcomes of a retrospective study using electronic health records that looked at the effect of a quality improvement initiative at the University of Colorado Hospital on readmission rates in two cohorts of 48 and 56 individuals with SLE.

Emily Bowers, MD, of the department of rheumatology at the University of Colorado at Denver, Aurora, and coauthors wrote that hospital readmission rates for SLE are as high as 36% for 30-day readmission. They are significantly higher than for other common chronic diseases such as heart failure, COPD, and diabetes. Readmission for SLE is associated with young age, ethnic or racial diversity, public health insurance, multiorgan involvement, and other comorbidities.

The intervention involved first alerting clinic nurses via the patient’s electronic medical record when the patient was discharged from hospital. The nurses would then call the patient within 48 hours to answer any questions and review their discharge information, and then consult with a rheumatologist on on-call if needed. This call was documented in the patient’s medical record.

In the preintervention cohort, there were 59 hospitalizations among 48 patients, 29% of which were followed by readmission within 30 days; 53% of these readmissions were lupus related. In the cohort that followed introduction of the intervention, there were 73 hospitalizations among 56 individuals, and 19% were followed by readmission within 30 days, 29% of which were lupus related.

After accounting for gender, age, race, and insurance type, the researchers calculated that there was an 89% higher odds of readmission in the nonintervention group than in the intervention group, but the difference was not statistically significant.

The authors noted that although the results were not statistically significant, the low cost of the intervention – requiring around 30 minutes of nursing time – meant even small reductions in the number of emergency department or hospital admissions would make it a cost-effective approach.

“Telephone outreach is an excellent method of providing additional support to patients, assessing clinical needs, reinforcing education about SLE, medications, and common complications such as drug side effects and infections, and allows for patients to ask pertinent questions to RN providers with expertise in the management of lupus,” the authors wrote.

The nurses also recorded qualitative information about the calls, which picked up some patient issues that could be addressed. For example, a patient was discharged with the wrong amount of prednisone, which the nurse was able to fix by adjusting the order and sending it to the pharmacy. Two other patients were confused by their medication instructions and were taking the medication incorrectly; the nurse arranged for the patients to come in for educational session. In another case, the nurse was able to arrange an infusion for the patient, and for one patient with concerns about infection, the nurse was able to advise that person on symptoms and how to seek care.

“To increase implementation of the intervention, we have discussed creating a discharge order set, which would include an automatic EMR message to the nurses,” the authors wrote. “Future studies should explore alternative ways of communicating with our patients after discharge, such as the use of text messaging, messaging through the patient portal in the EMR, or telehealth.”

The authors had no financial disclosures, and there was no outside financial support for the study.

A significant proportion of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and dysautonomia may have potentially treatable underlying autoimmune-associated small-fiber polyneuropathy (aaSFPN), pilot data suggest.

The findings, from a single-site study of 61 patients with ME/CFS, were presented August 21 at the virtual meeting of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis by Ryan Whelan, BS, a research assistant at Simmaron Research Institute, Incline Village, Nevada.

Recent evidence suggests an autoimmune etiology for some patients with ME/CFS, which is defined as experiencing for a period of at least 6 months profound, unexplained fatigue, postexertional malaise, and unrefreshing sleep, as well as cognitive dysfunction and/or orthostatic intolerance (OI).

OI is part of a spectrum of autonomic dysfunction commonly seen in ME/CFS patients, which may also include postural orthostatic tachycardia (POTS), peripheral temperature dysregulation and light sensitivity, neuropathic pain, and gastrointestinal complaints. Many of these symptoms overlap those reported by patients with aaSFPN, a common but underdiagnosed neurodegenerative disorder characterized by the loss of peripheral autonomic nerve fibers, Whelan explained.

Findings from the current study show that in more than half of ME/CFS patients, levels of at least one autoantibody were elevated. A majority had comorbid POTS or OI, and over a third had biopsy-confirmed aaSFPN.

“Given the overlap of symptoms and common etiological basis, it may be important to identify ME/CFS patients who present with comorbid aaSFPN, as it has been shown that immune modulatory agents, including intravenous gamma globulin [IVIG], reduce the autonomic symptom burden in aaSFPN patients,” Whelan said.

He noted that Anne Louise Oaklander, MD, a neurologist at Massachusetts General Hospital, Harvard Medical School, Boston, and colleagues previously linked aaSFPN with fibromyalgia. In addition, they’ve found a connection between small-fiber dysfunction and postexertional malaise, which is a hallmark ME/CFS symptom.

Asked to comment on Whelan’s presentation, IACFSME co-president Lily Chu, MD, told Medscape Medical News that the new findings are “valuable, because ME/CFS has always been looked upon as just subjective symptoms. When people have laboratory abnormalities, it can be due to a bunch of other causes, but...here’s pathology, here’s a biopsy of actual damage. It’s not just a transient finding. You can actually see it. ... It’s a solid concrete piece of evidence vs something that can fluctuate.”

Autoantibodies, Autonomic Dysfunction, and Small-Fiber Polyneuropathy

Whelan and colleagues conducted an extensive analysis of medical records of 364 patients with ME/CFS (72% female) to identify potential aaSFPN comorbidity. Such identifications were made on the basis of progress notes documenting autonomic dysfunction, laboratory results for serum autoantibodies, and questionnaire symptom self-reports.

They identified 61 patients as possibly having comorbid aaSFPN. Of those, 52% tested positive for at least 1 of 4 autoantibodies, including antimuscarinic cholinergic receptor 4 (47%), anti-beta-2 adrenergic (27%), antimuscarinic cholinergic 3 (25%), and anti-beta-1 adrenergic (13%). These autoantibodies were linked to ME/CFS in a recent Swedish cohort study.

“Evidence supports that these autoantibodies may bind to receptor sites, blocking ligands from reaching these receptors. Disturbances of adrenergic and cholinergic receptors by these autoantibodies may contribute to symptoms of autonomic dysfunction in ME/CFS,” Whelan said.

Although 22% of patients in the study group had POTS and 59% had OI, the authors found no correlation between autoantibody levels and either OI or POTS. However, 38% were confirmed to have small-fiber polyneuropathy on skin biopsy, and the vast majority of those patients (93%) had either POTS or OI.

IVIG May Be a Potential Treatment

Whelan notes that some data suggest that IVIG might help patients with small-fiber neuropathy, including those with autoimmunity.

In addition, he described anecdotal data from a single patient with ME/CFS who had neuropathic symptoms. The patient was treated at Simmaron. The 56-year-old received two IVIG infusions given 6 months apart. The patient experienced a dramatic reduction in levels of all four of the relevant autoantibodies and favorable symptom reduction, as shown in clinician follow-up records. “With the success of this case study, we intend to further evaluate IVIG as a potential treatment in ME/CFS patients. With this research, we hope to identify a subset of ME/CFS patients who will respond favorably to IVIG,” Whelan concluded.

Regarding use of IVIG, Chu commented, “We don’t know exactly how it works, but it seems to help certain conditions.” She pointed to another recent small study that reported clinical improvement in patients with ME/CFS through a different approach, immunoadsorption, for reducing the autoantibody levels.

Overall, Chu said, this line of research “is important because it shows there’s some type of abnormal biomarker for ME/CFS. And, it may lay a path toward understanding the pathophysiology of the disease and why people have certain symptoms, and could be used to target therapies. ... It’s intriguing.”

Whelan and Chu have disclosed no relevant financial relationships.

“Given the overlap of symptoms and common etiological basis, it may be important to identify ME/CFS patients who present with comorbid aaSFPN, as it has been shown that immune modulatory agents, including intravenous gamma globulin [IVIG], reduce the autonomic symptom burden in aaSFPN patients,” Whelan said.

He noted that Anne Louise Oaklander, MD, a neurologist at Massachusetts General Hospital, Harvard Medical School, Boston, and colleagues previously linked aaSFPN with fibromyalgia. In addition, they’ve found a connection between small-fiber dysfunction and postexertional malaise, which is a hallmark ME/CFS symptom.

Asked to comment on Whelan’s presentation, IACFSME co-president Lily Chu, MD, told Medscape Medical News that the new findings are “valuable, because ME/CFS has always been looked upon as just subjective symptoms. When people have laboratory abnormalities, it can be due to a bunch of other causes, but...here’s pathology, here’s a biopsy of actual damage. It’s not just a transient finding. You can actually see it. ... It’s a solid concrete piece of evidence vs something that can fluctuate.”

Autoantibodies, Autonomic Dysfunction, and Small-Fiber Polyneuropathy

Whelan and colleagues conducted an extensive analysis of medical records of 364 patients with ME/CFS (72% female) to identify potential aaSFPN comorbidity. Such identifications were made on the basis of progress notes documenting autonomic dysfunction, laboratory results for serum autoantibodies, and questionnaire symptom self-reports.

They identified 61 patients as possibly having comorbid aaSFPN. Of those, 52% tested positive for at least 1 of 4 autoantibodies, including antimuscarinic cholinergic receptor 4 (47%), anti-beta-2 adrenergic (27%), antimuscarinic cholinergic 3 (25%), and anti-beta-1 adrenergic (13%). These autoantibodies were linked to ME/CFS in a recent Swedish cohort study.

“Evidence supports that these autoantibodies may bind to receptor sites, blocking ligands from reaching these receptors. Disturbances of adrenergic and cholinergic receptors by these autoantibodies may contribute to symptoms of autonomic dysfunction in ME/CFS,” Whelan said.

Although 22% of patients in the study group had POTS and 59% had OI, the authors found no correlation between autoantibody levels and either OI or POTS. However, 38% were confirmed to have small-fiber polyneuropathy on skin biopsy, and the vast majority of those patients (93%) had either POTS or OI.

IVIG May Be a Potential Treatment

Whelan notes that some data suggest that IVIG might help patients with small-fiber neuropathy, including those with autoimmunity.

In addition, he described anecdotal data from a single patient with ME/CFS who had neuropathic symptoms. The patient was treated at Simmaron. The 56-year-old received two IVIG infusions given 6 months apart. The patient experienced a dramatic reduction in levels of all four of the relevant autoantibodies and favorable symptom reduction, as shown in clinician follow-up records. “With the success of this case study, we intend to further evaluate IVIG as a potential treatment in ME/CFS patients. With this research, we hope to identify a subset of ME/CFS patients who will respond favorably to IVIG,” Whelan concluded.

Regarding use of IVIG, Chu commented, “We don’t know exactly how it works, but it seems to help certain conditions.” She pointed to another recent small study that reported clinical improvement in patients with ME/CFS through a different approach, immunoadsorption, for reducing the autoantibody levels.

Overall, Chu said, this line of research “is important because it shows there’s some type of abnormal biomarker for ME/CFS. And, it may lay a path toward understanding the pathophysiology of the disease and why people have certain symptoms, and could be used to target therapies. ... It’s intriguing.”

Whelan and Chu have disclosed no relevant financial relationships.

A significant proportion of patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and dysautonomia may have potentially treatable underlying autoimmune-associated small-fiber polyneuropathy (aaSFPN), pilot data suggest.

The findings, from a single-site study of 61 patients with ME/CFS, were presented August 21 at the virtual meeting of the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis by Ryan Whelan, BS, a research assistant at Simmaron Research Institute, Incline Village, Nevada.

Recent evidence suggests an autoimmune etiology for some patients with ME/CFS, which is defined as experiencing for a period of at least 6 months profound, unexplained fatigue, postexertional malaise, and unrefreshing sleep, as well as cognitive dysfunction and/or orthostatic intolerance (OI).

OI is part of a spectrum of autonomic dysfunction commonly seen in ME/CFS patients, which may also include postural orthostatic tachycardia (POTS), peripheral temperature dysregulation and light sensitivity, neuropathic pain, and gastrointestinal complaints. Many of these symptoms overlap those reported by patients with aaSFPN, a common but underdiagnosed neurodegenerative disorder characterized by the loss of peripheral autonomic nerve fibers, Whelan explained.

Findings from the current study show that in more than half of ME/CFS patients, levels of at least one autoantibody were elevated. A majority had comorbid POTS or OI, and over a third had biopsy-confirmed aaSFPN.

A new retrospective analysis has found 1.5-2 cm to be the optimal length of a temporal artery biopsy for detecting giant cell arteritis. Longer lengths did not yield enough improvement in diagnosis to justify the increased risk of complications. The length calculation accounts for post-fixation shrinkage.

The study, published Aug. 20 in Lancet Rheumatology, represents an “important contribution” to help with the diagnosis of giant cell arteritis when a decision has been made to perform a temporal artery biopsy, according to authors of an editorial accompanying the study.

Giant cell arteritis is an inflammatory condition of medium and large arteries, usually affecting the aorta and proximal aorta. Diagnosis includes a combination of clinical presentation and imaging or histology via a temporal artery biopsy, but the optimal tissue length for a biopsy has not been established. Longer lengths were initially considered best because inflammation can be non-uniform, and a shorter length could therefore raise the risk of a false negative if it contained few signs of inflammation.

Studies in the 1990s and early 2000s concluded that biopsies 2-5 cm in length were optimal. But later studies determined that a minimum of just 0.5 cm was necessary. The European League Against Rheumatism updated its recommendations in 2018 and the British Society for Rheumatology followed suit in 2020, both with a suggested minimum length of 1.0 cm. Despite these guidances, the optimal biopsy length beyond 1 cm remains unknown.

For the study, first author Raymond Chu, MD, of the University of Alberta Hospital, Edmonton, reviewed electronic medical records of all patients who underwent temporal artery biopsies in Alberta between Jan. 1, 2008, and Jan. 1, 2018. A single pathologist reviewed all positive findings to ensure uniformity of pathological interpretation. When the reviewer disagreed with the initial diagnosis, researchers removed the result from the analysis.

The study included 1,203 biopsies from 1,176 patients at 22 institutions. A total of 13 positive biopsies were removed following pathologist review. The median biopsy length was 1.3 cm. Median erythrocyte sedimentation rate (ESR) was 41 mm/hour, and median C-reactive protein (CRP) level was 14.7 mg/L. Univariate analyses found associations between positive biopsy and increased age (75.3 vs. 71.3 years; P < .0001), increased ESR (57 vs. 36 mm/hour; P < .0001), lower CRP (12.1 vs. 41.8 mg/L; P < .0001), and longer biopsy length (1.6 vs. 1.2 cm; P = .0025).

In a multivariate analysis, the only variables associated with a positive biopsy were age (adjusted odds ratio [aOR], 1.04; P = .0001), lower CRP levels (aOR, 1.01; P = .0006), and biopsy length (aOR, 1.22; P = .047). The researchers then stratified the sample by biopsy length, using categories of < 0.5 cm, 0.5-1.0 cm, 1.0-1.5 cm, 1.5-2.0 cm, 2.0-2.5 cm, and ≥ 2.5 cm. They identified the two top change points according to the Akaike information criterion as 1.5 cm and 2.0 cm, but only 1.5 cm was statistically significant (≥ 1.5 versus < 1.5; OR, 1.57; P = .011).

Accounting for an average 8% contraction following excision, the researchers recommend an optimal pre-fixation biopsy length of 1.5-2.0 cm.

Some previous studies had suggested no association between increased sample length and false negatives, but they were based on small sample sizes. The current study is limited by its retrospective design and lack of treatment data. The lack of marked inflammation in the sample population suggests that patients were frequently treated empirically with glucocorticoids, and this could have increased the frequency of false negative biopsies, the researchers said.

In the accompanying editorial, Frank Buttgereit, MD, of Charité University Medicine in Berlin and Christian Dejaco, MD, PhD, of the Medical University of Graz (Austria) point out that ultrasound is now often used for the diagnosis of giant cell arteritis, following clinical examination and laboratory testing. When it has been determined that biopsy is necessary, they said that it is imperative that the harvest be carried out by an experienced physician, and the new study provides a useful contribution through its clear recommendation for biopsy length.

The authors of the editorial also point out the importance of experienced pathologists, but interpretation is subject to inter- and intraobserver variability, as shown in a previous study that found that ultrasound and histology have similar reliability.

The study received no funding. Several authors reported receiving personal fees from Hoffmann-LaRoche and serving as site primary investigators for industry-sponsored vasculitis trials.

A new study has quantified cancer risk factors in patients with systemic lupus erythematosus, including smoking and the use of certain medications.

“As expected, older age was associated with cancer overall, as well as with the most common cancer subtypes,” wrote Sasha Bernatsky, MD, PhD, of McGill University, Montreal, and coauthors. The study was published in Arthritis Care & Research.

To determine the risk of cancer in people with clinically confirmed incident systemic lupus erythematosus (SLE), the researchers analyzed data from 1,668 newly diagnosed lupus patients with at least one follow-up visit. All patients were enrolled in the Systemic Lupus International Collaborating Clinics inception cohort from across 33 different centers in North America, Europe, and Asia. A total of 89% (n = 1,480) were women, and 49% (n = 824) were white. The average follow-up period was 9 years.

Of the 1,668 SLE patients, 65 developed some type of cancer. The cancers included 15 breast;, 10 nonmelanoma skin; 7 lung; 6 hematologic, 6 prostate; 5 melanoma; 3 cervical; 3 renal; 2 gastric; 2 head and neck; 2 thyroid; and 1 rectal, sarcoma, thymoma, or uterine. No patient had more than one type, and the mean age of the cancer patients at time of SLE diagnosis was 45.6 (standard deviation, 14.5).

Almost half of the 65 cancers occurred in past or current smokers, including all of the lung cancers, while only 33% of patients without cancers smoked prior to baseline. After univariate analysis, characteristics associated with a higher risk of all cancers included older age at SLE diagnosis (adjusted hazard ratio, 1.05; 95% confidence interval, 1.03-1.06), White race/ethnicity (aHR 1.34; 95% CI, 0.76-2.37), and smoking (aHR 1.21; 95% CI, 0.73-2.01).

After multivariate analysis, the two characteristics most associated with increased cancer risk were older age at SLE diagnosis and being male. The analyses also confirmed that older age was a risk factor for breast cancer (aHR 1.06; 95% CI, 1.02-1.10) and nonmelanoma skin cancer (aHR, 1.06; 95% CI, 1.02-1.11), while use of antimalarial drugs was associated with a lower risk of both breast (aHR, 0.28; 95% CI, 0.09-0.90) and nonmelanoma skin (aHR, 0.23; 95% CI, 0.05-0.95) cancers. For lung cancer, the highest risk factor was smoking 15 or more cigarettes a day (aHR, 6.64; 95% CI, 1.43-30.9); for hematologic cancers, it was being in the top quartile of SLE disease activity (aHR, 7.14; 95% CI, 1.13-45.3).

The authors acknowledged their study’s limitations, including the small number of cancers overall and purposefully not comparing cancer risk in SLE patients with risk in the general population. Although their methods – “physicians recording events at annual visits, confirmed by review of charts” – were recognized as very suitable for the current analysis, they noted that a broader comparison would “potentially be problematic due to differential misclassification error” in cancer registry data.

Two of the study’s authors reported potential conflicts of interest, including receiving grants and consulting and personal fees from various pharmaceutical companies. No other potential conflicts were reported.

After multivariate analysis, the two characteristics most associated with increased cancer risk were older age at SLE diagnosis and being male. The analyses also confirmed that older age was a risk factor for breast cancer (aHR 1.06; 95% CI, 1.02-1.10) and nonmelanoma skin cancer (aHR, 1.06; 95% CI, 1.02-1.11), while use of antimalarial drugs was associated with a lower risk of both breast (aHR, 0.28; 95% CI, 0.09-0.90) and nonmelanoma skin (aHR, 0.23; 95% CI, 0.05-0.95) cancers. For lung cancer, the highest risk factor was smoking 15 or more cigarettes a day (aHR, 6.64; 95% CI, 1.43-30.9); for hematologic cancers, it was being in the top quartile of SLE disease activity (aHR, 7.14; 95% CI, 1.13-45.3).

The authors acknowledged their study’s limitations, including the small number of cancers overall and purposefully not comparing cancer risk in SLE patients with risk in the general population. Although their methods – “physicians recording events at annual visits, confirmed by review of charts” – were recognized as very suitable for the current analysis, they noted that a broader comparison would “potentially be problematic due to differential misclassification error” in cancer registry data.

Two of the study’s authors reported potential conflicts of interest, including receiving grants and consulting and personal fees from various pharmaceutical companies. No other potential conflicts were reported.

Patients with sarcoidosis have an increased risk of heart failure and other adverse outcomes, including all-cause mortality, according to a decade-long nationwide study of Danish patients with the inflammatory disease.

“Although these findings are suggestive of the need for regular monitoring of cardiac manifestations in patients with sarcoidosis, it is important to emphasize that no causal relationships can be established from an observational study. Further studies are therefore needed to confirm our findings,” said first author Adelina Yafasova, MB, of Copenhagen University Hospital in Denmark, in an interview. The study was published in the Journal of the American College of Cardiology.

To determine the long-term risk of cardiac outcomes, and beyond – including incident heart failure; a composite of implantable cardioverter-defibrillator (ICD) implantation, ventricular arrhythmias or cardiac arrest; and all-cause mortality – Dr. Yafasova and her colleagues analyzed data from all Danish residents 18 years or older who were diagnosed with sarcoidosis from 1996 to 2016. Patients with any history of cardiac events were excluded. Of the 12,883 diagnosed patients, 11,834 were matched with subjects from a nationwide background population of more than 47,000 based on age, sex, and comorbidity. The median age of both populations was 42.8 (33.1-55.8) and 54.3% were men.

Median follow-up was 8.2 years for the sarcoidosis population and 8.4 years for the background population. The absolute 10-year risk of heart failure was 3.18% (95% confidence interval, 2.83%-3.57%) for sarcoidosis patients and 1.72% (95% CI, 1.58%-1.86%) for their matched controls. The 10-year risk for the composite of ICD implantation, ventricular arrhythmias and cardiac arrest was 0.96% (95% CI, 0.77%-1.18%) for sarcoidosis patients and 0.45% (95% CI, 0.38%-0.53%) for the background population.

For all-cause mortality, the 10-year risk was 10.88% (95% CI, 10.23%-11.55%) for sarcoidosis patients and 7.43% (95% CI, 7.15%-7.72%) for the background population. In a secondary analysis that compared all-cause mortality between the 364 sarcoidosis patients who developed heart failure and the 1,456 patients with heart failure without a history of sarcoidosis, the sarcoidosis group had a 35% higher rate than the nonsarcoidosis group (adjusted hazard ratio 1.35; 95% CI, 1.10-1.64).

“It’s not necessarily surprising that sarcoidosis patients would have a higher rate of heart failure,” said Melissa A. Lyle, MD, of the Mayo Clinic in Jacksonville, Fla., in an interview. “But the key takeaway is that sarcoidosis was associated with a higher rate of all-cause mortality compared to patients with heart failure and no sarcoidosis. That was more of a surprise.”

“There’s been some discrepancy in previous studies describing the cardiovascular outcomes in sarcoidosis,” Dr. Lyle added, “so I think this study provides excellent information while also highlighting the need for additional large-scale studies. We need to have further data on cardiovascular outcomes, which will allow us to refine the consensus statements and guidelines for management and the diagnosis of cardiac sarcoidosis.”

Dr. Lyle and Leslie T. Cooper Jr., MD, also of the Mayo Clinic, extrapolated on those thoughts in an editorial that accompanied the study. In it, the two authors praised the size and lengthy follow-up of the study, while noting its limitations. Specifically, they stressed that the study’s Danish population “may not be representative of other general populations” because of notable differences in ethnicity, age, and comorbidities.

That said, they reinforced that the study did feature “important takeaways” and that its findings emphasize the “need for monitoring for cardiac manifestations in patients with systemic sarcoidosis.”

In addition to the limitations noted in the editorial, the study’s authors acknowledged that the observational nature limited its “assessment of cause-effect relationships” and that the diagnosis codes for sarcoidosis had not been validated in the Danish National Patient Registry.

The authors of both the study and the editorial reported no conflicts of interest.

Cachexia developed in 56% of adults with systemic lupus erythematosus over a 5-year period, and 18% did not recover their weight, based on data from more than 2,000 patients.

Sara Freeman/MDedge News

Although weight loss is common in patients with systemic lupus erythematosus (SLE), cachexia, a disorder of involuntary weight loss, is largely undescribed in SLE patients, wrote George Stojan, MD, of Johns Hopkins University, Baltimore, and colleagues. Cachexia has been described in a range of disorders, including heart failure, renal disease, and rheumatoid arthritis, they said. “Cachexia has been shown to lead to progressive functional impairment, treatment-related complications, poor quality of life, and increased mortality,” they added.

In a study published in Arthritis Care & Research, the investigators reviewed data from the Hopkins Lupus Cohort, consisting of all SLE patients seen at a single center who are followed at least quarterly.

The study population included 2,452 SLE patients older than 18 years who had their weight assessed at each clinic visit. The average follow-up period was 7.75 years, and the average number of weight measurements per patient was nearly 24.

Cachexia was defined as a 5% stable weight loss in 6 months without starvation relative to the average weight in all prior cohort visits; and/or weight loss of more than 2% without starvation relative to the average weight in all prior cohort visits in addition to a body mass index less than 20 kg/m².

Overall, the risk for cachexia within 5 years of entering the study was significantly higher in patients with a BMI less than 20, current steroid use, vasculitis, lupus nephritis, serositis, hematologic lupus, positive anti-double strand DNA (anti-dsDNA), anti-Smith (anti-Sm), and antiribonucleoprotein (anti-RNP), the researchers noted. After adjustment for prednisone use, cachexia remained significantly associated with lupus nephritis, vasculitis, serositis, and hematologic lupus.

Future organ damage including cataracts, retinal change or optic atrophy, cognitive impairment, cerebrovascular accidents, cranial or peripheral neuropathy, pulmonary hypertension, pleural fibrosis, angina or coronary bypass, bowel infarction or resection, osteoporosis, avascular necrosis, and premature gonadal failure were significantly more likely among patients with intermittent cachexia, compared with those with continuous or no cachexia. Patients with continuous cachexia were significantly more likely to experience an estimated glomerular filtration rate less than 50 mL/min/1.73 m², proteinuria greater than 3.5 g/day, and end-stage renal disease.

The patients who never developed cachexia were significantly less likely to develop malignancies, diabetes, valvular disease, or cardiomyopathy than were those who did have cachexia, the researchers said.

The mechanisms of action for cachexia in SLE remain unclear, but studies in cancer patients may provide some guidance, the researchers noted. “Tumors secrete a range of procachexia factors thought to be unique to cancer-related cachexia, and colloquially termed the ‘tumor secretome,’ ” they said. “Every single proinflammatory cytokine mentioned as part of the tumor secretome has a role in lupus pathogenesis,” suggesting a possible common pathway to cachexia across different diseases, they said.

The study findings were limited by several factors, mainly the use of BMI to measure weight “since BMI is a rather poor indicator of percent of body fat,” the researchers noted. “Ideally, cachexia would be defined as sarcopenia based on body composition evaluation with a dual x-ray absorptiometry,” they wrote.

The study was supported by the National Institutes of Health and the NIH Roadmap for Medical Research. The researchers had no financial conflicts to disclose.

Use of the 2019 EULAR/ACR criteria for systemic lupus erythematosus identified an additional 17% of lupus patients in a cohort of 133 women with undifferentiated connective tissue disease.

Several studies have applied the 2019 EULAR/ACR criteria for systemic lupus erythematosus (SLE) to different patient populations, wrote Massimo Radin, MD, of S. Giovanni Bosco Hospital, Turin, Italy, and colleagues.

“However, it is unknown if the new classifications criteria for SLE might impact on the categorization of patients previously diagnosed with undifferentiated connective tissue disease (UCTD),” they said in a brief report published in Arthritis Care & Research.

In addition, “being classified or not as having SLE may pose clinical and logistic consequences, as patients with a diagnosis of ‘SLE’ might be followed up according to a specific local protocol and have in-label access to certain medications (such as biologics) or may be eligible for the participation in clinical trials,” they wrote.

The investigators applied the 2019 EULAR/ACR criteria to a cohort of 133 women with UCTD but no other diagnosis. The average age of the women was 38 years; the average disease duration was 10 years. Patients who scored 10 points or more on positive clinical and immunological domains at the start of the study were classified as SLE under the 2019 EULAR/ACR criteria.

Overall, 22 patients (17%) met the classification criteria for SLE at the time of their first pregnancy.

Compared with the other patients in the cohort who were not classified as SLE, patients classified as SLE under the 2019 EULAR/ACR criteria had significantly higher frequency of mucocutaneous manifestations (5% vs. 23%), arthritis (17% vs. 59%), isolated urine abnormalities (1% vs. 18%), and highly specific antibodies (15% vs. 50%).

In addition, patients who met the 2019 EULAR/ACR SLE criteria were significantly more likely to meet the ACR 1997 and SLICC criteria after an average follow-up of 9 years compared with the rest of the cohort (18.2% vs. 1.8%). Patients who met the 2019 EULAR/ACR criteria also had significantly shorter disease duration than that of the other patients in the UCTD cohort (8.23 years vs. 10.7 years) and were significantly more likely to develop preeclampsia during pregnancy (18% vs. 0%).

The findings were limited by several factors including the retrospective design of the study and possible lack of generalizability to male patients, the researchers noted.

The results support the need for improved classification criteria for UCTD, as early identification of specific conditions can help guide treatment and reduce the risk of more severe symptoms and complications, the authors said.

“When discriminating between conditions with a marked overlap, such as SLE and UCTD, the proposal of new classification criteria should balance specificity and sensitivity,” the researchers wrote. “When developing new classification criteria, one approach is to select patients and the control groups as representative as possible of the settings (the medical practices) in which these criteria will be used.”

The study received no outside funding. The researchers had no financial conflicts to disclose.

The investigators applied the 2019 EULAR/ACR criteria to a cohort of 133 women with UCTD but no other diagnosis. The average age of the women was 38 years; the average disease duration was 10 years. Patients who scored 10 points or more on positive clinical and immunological domains at the start of the study were classified as SLE under the 2019 EULAR/ACR criteria.

Overall, 22 patients (17%) met the classification criteria for SLE at the time of their first pregnancy.

Compared with the other patients in the cohort who were not classified as SLE, patients classified as SLE under the 2019 EULAR/ACR criteria had significantly higher frequency of mucocutaneous manifestations (5% vs. 23%), arthritis (17% vs. 59%), isolated urine abnormalities (1% vs. 18%), and highly specific antibodies (15% vs. 50%).

In addition, patients who met the 2019 EULAR/ACR SLE criteria were significantly more likely to meet the ACR 1997 and SLICC criteria after an average follow-up of 9 years compared with the rest of the cohort (18.2% vs. 1.8%). Patients who met the 2019 EULAR/ACR criteria also had significantly shorter disease duration than that of the other patients in the UCTD cohort (8.23 years vs. 10.7 years) and were significantly more likely to develop preeclampsia during pregnancy (18% vs. 0%).

The findings were limited by several factors including the retrospective design of the study and possible lack of generalizability to male patients, the researchers noted.

The results support the need for improved classification criteria for UCTD, as early identification of specific conditions can help guide treatment and reduce the risk of more severe symptoms and complications, the authors said.

“When discriminating between conditions with a marked overlap, such as SLE and UCTD, the proposal of new classification criteria should balance specificity and sensitivity,” the researchers wrote. “When developing new classification criteria, one approach is to select patients and the control groups as representative as possible of the settings (the medical practices) in which these criteria will be used.”

The study received no outside funding. The researchers had no financial conflicts to disclose.
