Severe renal arteriosclerosis may indicate cardiovascular risk in lupus nephritis
Severe renal arteriosclerosis was associated with a ninefold increased risk of atherosclerotic cardiovascular disease in patients with lupus nephritis, based on data from an observational study of 189 individuals.
Atherosclerotic cardiovascular disease (ASCVD) has traditionally been thought to be a late complication of systemic lupus erythematosus (SLE), but this has been challenged in recent population-based studies of patients with SLE and lupus nephritis (LN) that indicated an early and increased risk of ASCVD at the time of diagnosis. However, it is unclear which early risk factors may predispose patients to ASCVD, Shivani Garg, MD, of the University of Wisconsin, Madison, and colleagues wrote in a study published in Arthritis Care & Research.
In patients with IgA nephropathy and renal transplantation, previous studies have shown that severe renal arteriosclerosis (r-ASCL) based on kidney biopsies at the time of diagnosis predicts ASCVD, but “a few studies including LN biopsies failed to report a similar association between the presence of severe r-ASCL and ASCVD occurrence,” possibly because of underreporting of r-ASCL. Dr. Garg and colleagues also noted the problem of underreporting of r-ASCL in their own previous study of its prevalence in LN patients at the time of diagnosis.
To get a more detailed view of how r-ASCL may be linked to early occurrence of ASCVD in LN patients, Dr. Garg and coauthors identified 189 consecutive patients with incident LN who underwent diagnostic biopsies between 1994 and 2017. The median age of the patients was 25 years, 78% were women, and 73% were white. The researchers developed a composite score for r-ASCL severity based on reported and overread biopsies.
Overall, 31% of the patients had any reported r-ASCL, and 7% had moderate-severe r-ASCL. After incorporating systematically reexamined r-ASCL grades, the prevalence of any and moderate-severe r-ASCL increased to 39% and 12%, respectively.
Based on their composite of reported and overread r-ASCL grade, severe r-ASCL in diagnostic LN biopsies was associated with a ninefold increased risk of ASCVD.
The researchers identified 22 incident ASCVD events over an 11-year follow-up for an overall 12% incidence of ASCVD in LN. ASCVD was defined as ischemic heart disease (including myocardial infarction, coronary artery revascularization, abnormal stress test, abnormal angiogram, and events documented by a cardiologist); stroke and transient ischemic attack (TIA); and peripheral vascular disease. Incident ASCVD was defined as the first ASCVD event between 1 and 10 years after LN diagnosis.
The most common ASCVD events were stroke or TIA (12 patients), events related to ischemic heart disease (7 patients), and events related to peripheral vascular disease (3 patients).
Lack of statin use
The researchers also hypothesized that the presence of gaps in statin use among eligible LN patients would be present in their study population. “Among the 20 patients with incident ASCVD events after LN diagnosis in our cohort, none was on statin therapy at the time of LN diagnosis,” the researchers said, noting that current guidelines from the American College of Rheumatology and the European League Against Rheumatism (now known as the European Alliance of Associations for Rheumatology) recommend initiating statin therapy at the time of LN diagnosis in all patients who have hyperlipidemia and chronic kidney disease (CKD) stage ≥3. “Further, 11 patients (55%) met high-risk criteria (hyperlipidemia and CKD stage ≥3) to implement statin therapy at the time of LN diagnosis, yet only one patient (9%) was initiated on statin therapy.” In addition, patients with stage 3 or higher CKD were more likely to develop ASCVD than patients without stage 3 or higher CKD, they said.
The study findings were limited by several factors including the majority white study population, the ability to overread only 25% of the biopsies, and the lack of data on the potential role of chronic lesions in ASCVD, the researchers noted. However, the results were strengthened by the use of a validated LN cohort, and the data provide “the basis to establish severe composite r-ASCL as a predictor of ASCVD events using a larger sample size in different cohorts,” they said.
The study received no outside funding. The researchers had no financial conflicts to disclose.

Treprostinil offers some benefits for patients with ILD-associated pulmonary hypertension
and was associated with some additional clinical benefits, according to a new study published in the New England Journal of Medicine.
To investigate treprostinil therapy for pulmonary hypertension in this subset of patients with lung disease, Aaron Waxman, MD, PhD, of Brigham and Women’s Hospital in Boston, and his fellow researchers launched the multicenter, randomized, double-blind, placebo-controlled INCREASE trial. They assigned 163 patients to the inhaled treprostinil group – administered via an ultrasonic, pulsed-delivery nebulizer over 16 weeks – and 163 patients to the placebo group. Their average age was 66.5 years, 73% were white, and 47% were female
At baseline, the mean 6-minute walk distance (6MWD) for all patients was 259.6 m. After 16 weeks, the treprostinil group gained a mean of 21.08 m in 6MWD, and the placebo group lost 10.04 m. The least-squares mean difference between the groups from baseline in the 6MWD was 31.12 m (95% confidence interval, 16.85-45.39; P < .001). After sensitivity analysis with multiple imputation, the difference remained significant at 30.97 m (95% CI, 16.53-45.41; P < .001).
In a comparison of N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels from baseline to 16 weeks, the treprostinil group saw a decrease of 15% while the placebo group’s levels increased by 46% (treatment ratio 0.58; 95% CI, 0.47-0.72; P < .001). Clinical worsening occurred in 37 patients (23%) in the treprostinil group and 54 patients (33%) in the placebo group (hazard ratio, 0.61; 95% CI, 0.40-0.92; P = .04), while serious adverse events occurred in 23.3% of the patients on treprostinil and 25.8% of the patients on placebo. There was no significant difference between groups in patient-reported quality of life, as assessed via the St. George’s Respiratory Questionnaire.
“There was no guarantee that this was going to work in this condition,” said Adriano Tonelli, MD, of the department of pulmonary medicine at the Cleveland Clinic, in an interview. “Several small studies have tried different medications, for pulmonary hypertension or otherwise, in patients with interstitial lung disease with minimal effect, if any. Given that all the prior studies were not categorically positive, the expectation, at least on my end, was that we needed to wait and see.” Dr. Tonelli and coauthors published a post hoc analysis of inhaled treprostinil studied in the TRIUMPH and BEAT trials.
Next steps: Assess clinical outcomes after inhaled treprostinil
Although the results of this study by Waxman et al, are encouraging, and the need for a treatment in this type of pulmonary hypertension is very real, more narrowing down will be needed to confirm the benefits of inhaled treprostinil, wrote Darren B. Taichman, MD, PhD, of the University of Pennsylvania in an accompanying editorial. He wrote, “After all, patients and physicians may reason, ‘It can’t hurt.’ Unfortunately, however, it could. Therapies approved for pulmonary arterial hypertension have been studied in patients with [ILD]-associated pulmonary hypertension and have shown inconsistent results, with some studies showing no benefit or suggesting harm.”
While the 6MWD has been used as an end point in previous drug trials for pulmonary arterial hypertension, Dr. Taichman wrote that improvements in such a variable were “probably too modest to be unequivocally consequential for many patients.” To confirm the benefits – and detriments – of treatments like inhaled treprostinil, it’s time for studies to focus on clinical end points, he stated, including hospitalizations, disease progression, and death.
He also highlighted the disparity between a treatment that led to increased walk distance and decreased clinical worsening yet did not register an improvement in health-related quality of life. He noted that the oft-cited minimal clinically important difference for 6MWD is approximately 30 m – similar to the difference recorded here. That said, he wrote, “prevention of deterioration is not to be ignored, even if it does not make a patient feel better.”
Regarding quality of life, Dr. Tonelli observed that this questionnaire, standard fare in respiratory research, may not have been perfectly suited for this particular study.
“You have to put it in the context of, ‘How good is the questionnaire to capture a difference in this particular disease over a 16-week period?’ ” he said. “It might not be sensitive enough to capture a significant change. The questionnaire was not developed for pulmonary hypertension in interstitial lung disease, of course. It was developed more generically. It may not capture all that you need to show significance.”
The investigators acknowledged the study’s other potential limitations, including a short duration, a notable percentage of patients who discontinued the trial early, and the fact that clinical worsening and exacerbation of disease were investigator reported and not confirmed by an independent committee.
As for next steps in assessing pulmonary hypertension treatments, Dr. Tonelli pointed to the direction of future research. “The other big study that needs to come out in our field, and I believe it’s being worked on, is inhaled treprostinil in pulmonary hypertension due to chronic obstructive pulmonary disease [COPD],” he said. “That’s a major unmet need; the COPD population is larger than the population for interstitial lung disease, and one would wonder whether inhaled treprostinil would benefit those patients as well. At the moment, we have no treatments for that condition. In the future, a COPD study will be needed.”

Ehlers-Danlos syndrome associated with various complications in hospitalized patients
Hospitalized patients with Ehlers-Danlos syndrome (EDS) are more likely to have gastrointestinal, cardiovascular, autonomic, and allergic disorders than are hospitalized patients who do not have EDS, according to a new study of hospital outcomes in these four areas.
“Further research is necessary to explore the prevalence of these manifestations in the different subtypes of EDS and in outpatient population,” wrote Rachel S. Brooks of the University of Connecticut, Farmington, and her coauthors. The study was published in Rheumatology.
To investigate previously observed connections between EDS and these four types of complications, the researchers launched a case-control study using hospital records from the 2016 National Inpatient Sample. A total of 2,007 patients with EDS were identified via ICD-10 code and matched with 4,014 non-EDS patients according to 5-year age intervals, sex, and month of admission. EDS patients had an average age of nearly 37, and 84% were female. The average hospitalization was lengthier for EDS patients (4.77 days) than for controls (4.07 days).
GI conditions were found in 44% of EDS patients, compared with 18% of controls (odds ratio, 3.57; 95% confidence interval, 3.17-4.02; P < .0001). Among the more likely conditions were functional disorders of the stomach (OR, 5.18; 95% CI, 2.16-12.42; P < .0001), unspecified abdominal pain (OR, 3.97; 95% CI, 2.34-6.73; P < .0001), irritable bowel syndrome (OR, 7.44; 95% CI, 5.07-10.94; P < .0001), and nausea (OR, 3.20; 95% CI, 1.95-5.24; P < .0001).
Autonomic dysfunction was found in 20% of EDS patients, compared with 6% of controls (OR, 4.45; 95% CI, 3.71-5.32; P < .0001). They were significantly more likely to have postural orthostatic tachycardia syndrome (OR, 223.77; 95% CI, 31.21-1604.46; P < .0001), orthostatic hypotension (OR, 8.98; 95% CI, 5.36-15.03; P < .0001), syncope (OR, 3.62; 95% CI, 2.23-5.82; P < .0001), and other autonomic nervous system disorders (OR, 54.72; 95% CI, 7.43-403.00; P < .0001).
Food allergies were also considerably more likely to occur in EDS patients (OR, 3.88; 95% CI, 2.65-5.66; P < .0001), as were cardiovascular complications like mitral valve disorders, aortic aneurysm, and cardiac dysrhythmias (OR, 6.16; 95% CI, 4.60-8.23; P < .0001). Although EDS patients were more likely to have hospital stays that lasted longer than 4 days, there was no notable difference in mortality (OR, 0.79; 95% CI, 0.41-1.50; P = .47).
After multivariate regression analysis that adjusted for age, sex, race, and smoking status, EDS patients were more likely to have GI (OR, 3.53; 95% CI, 3.08-4.03; P < .0001), autonomic (OR, 4.13; 95% CI, 3.40-5.01; P < .0001), allergic (OR, 3.92; 95% CI, 2.57-5.98; P < .0001), and cardiovascular complications (OR, 5.82; 95% CI, 4.21-8.03; P < .0001).
Shining a much-needed light on the conditions associated with EDS
“Anyone who takes care of patients with EDS has likely seen some of these complications before and knows they can occur,” Jordan T. Jones, DO, a pediatric rheumatologist at Children’s Mercy Hospital in Kansas City, Mo., said in an interview. “I think this study legitimizes what many who take care of patients with EDS know to be true, and for those who don’t, it brings a lot of attention to many of the symptoms and associated conditions.”
He did, however, draw a conclusion that differed from one of the researchers’ chief observations.
“They note that these patients have a longer-than-average hospital stay, suggesting that EDS may be linked to adverse complications during hospitalization,” he said. “I think the reason for longer-than-average hospital stays is due to the number of symptoms and complexity of these patients, which can lead to delays in diagnosis. The complexity can lead to more involved evaluation that keeps them in the hospital longer than usual. Another reason for longer-than-average hospital stays that I’ve seen is the presentation of severe and chronic pain, which can be difficult to treat in the hospital and then transition to outpatient therapy. An inpatient hospitalization is not always the best place to treat chronic pain symptoms, which can drag out a hospital stay.”
He also highlighted the lack of discussion regarding musculoskeletal complications, which he sees as one of the most common symptoms related to EDS.
“As a rheumatologist, I see many patients with EDS present with chronic pain, chronic muscle weakness, and chronic fatigue. If you think about the joint laxity with EDS, these patients are a perfect setup to develop tight, weak muscles, which leads to a lot of musculoskeletal pain and fatigue.”
That said, he ultimately emphasized the clear benefits of such a large study on such an under-researched subject.
“We think EDS is more common than is reported,” he said. “But despite that, there are still a lot of people who don’t know about EDS, understand it, or appreciate how to evaluate for it. One of the best things this study does is bring more visibility to this disease and the associated conditions related to it.”
The authors declared no potential conflicts of interest.

Hospitalized patients with Ehlers-Danlos syndrome (EDS) are more likely to have gastrointestinal, cardiovascular, autonomic, and allergic disorders than are hospitalized patients who do not have EDS, according to a new study of hospital outcomes in these four areas.
“Further research is necessary to explore the prevalence of these manifestations in the different subtypes of EDS and in outpatient population,” wrote Rachel S. Brooks of the University of Connecticut, Farmington, and her coauthors. The study was published in Rheumatology.
To investigate previously observed connections between EDS and these four types of complications, the researchers launched a case-control study using hospital records from the 2016 National Inpatient Sample. A total of 2,007 patients with EDS were identified via ICD-10 code and matched with 4,014 non-EDS patients according to 5-year age intervals, sex, and month of admission. EDS patients had an average age of nearly 37, and 84% were female. The average hospitalization was lengthier for EDS patients (4.77 days) than for controls (4.07 days).
GI conditions were found in 44% of EDS patients, compared with 18% of controls (odds ratio, 3.57; 95% confidence interval, 3.17-4.02; P < .0001). Among the more likely conditions were functional disorders of the stomach (OR, 5.18; 95% CI, 2.16-12.42; P < .0001), unspecified abdominal pain (OR, 3.97; 95% CI, 2.34-6.73; P < .0001), irritable bowel syndrome (OR, 7.44; 95% CI, 5.07-10.94; P < .0001), and nausea (OR, 3.20; 95% CI, 1.95-5.24; P < .0001).
Autonomic dysfunction was found in 20% of EDS patients, compared with 6% of controls (OR, 4.45; 95% CI, 3.71-5.32; P < .0001). They were significantly more likely to have postural orthostatic tachycardia syndrome (OR, 223.77; 95% CI, 31.21-1604.46; P < .0001), orthostatic hypotension (OR, 8.98; 95% CI, 5.36-15.03; P < .0001), syncope (OR, 3.62; 95% CI, 2.23-5.82; P < .0001), and other autonomic nervous system disorders (OR, 54.72; 95% CI, 7.43-403.00; P < .0001).
Food allergies were also considerably more likely to occur in EDS patients (OR, 3.88; 95% CI, 2.65-5.66; P < .0001), as were cardiovascular complications like mitral valve disorders, aortic aneurysm, and cardiac dysrhythmias (OR, 6.16; 95% CI, 4.60-8.23; P < .0001). Although EDS patients were more likely to have hospital stays that lasted longer than 4 days, there was no notable difference in mortality (OR, 0.79; 95% CI, 0.41-1.50; P = .47).
After multivariate regression analysis that adjusted for age, sex, race, and smoking status, EDS patients were more likely to have GI (OR, 3.53; 95% CI, 3.08-4.03; P < .0001), autonomic (OR, 4.13; 95% CI, 3.40-5.01; P < .0001), allergic (OR, 3.92; 95% CI, 2.57-5.98; P < .0001), and cardiovascular complications (OR, 5.82; 95% CI, 4.21-8.03; P < .0001).

High hydroxychloroquine blood level may lower thrombosis risk in lupus
Maintaining an average hydroxychloroquine whole blood level above 1,068 ng/mL significantly reduced the risk of thrombosis in adults with systemic lupus erythematosus, based on data from 739 patients.
Hydroxychloroquine (HCQ) is a common treatment for systemic lupus erythematosus (SLE); studies suggest that it may protect against thrombosis, but the optimal dosing for this purpose remains unknown, wrote Michelle Petri, MD, of Johns Hopkins University, Baltimore, and colleagues. In a study published in Arthritis & Rheumatology, the researchers examined data on HCQ levels from 739 adults with SLE who were part of the Hopkins Lupus Cohort, a longitudinal study of outcomes in SLE patients. Of these, 38 (5.1%) developed thrombosis during 2,330 person-years of follow-up.
Overall, the average HCQ blood level was significantly lower in patients who experienced thrombosis, compared to those who did not (720 ng/mL vs. 935 ng/mL; P = .025). “Prescribed hydroxychloroquine doses did not predict hydroxychloroquine blood levels,” the researchers noted.
In addition, Dr. Petri and associates found a dose-response relationship in which the thrombosis rate declined approximately 13% for every 200-ng/mL increase in the mean HCQ blood level measurement and for the most recent HCQ blood level measurement after controlling for factors that included age, ethnicity, lupus anticoagulant, low C3, and hypertension.
In a multivariate analysis, thrombotic events decreased by 69% in patients with mean HCQ blood levels greater than 1,068 ng/mL, compared to those with average HCQ blood levels less than 648 ng/mL.
The average age of the patients at the time HCQ measurements began was 43 years, 93% were female, and 46% were White. Patients visited a clinic every 3 months, and HCQ levels were determined by liquid chromatography-tandem mass spectrometry.
“Between-person and within-person correlation coefficients were used to measure the strength of the linear association between HCQ blood levels and commonly prescribed HCQ doses from 4.5 to 6.5 mg/kg,” the researchers said.
Higher doses of HCQ have been associated with increased risk for retinopathy, and current guidelines recommend using less than 5 mg/kg of ideal body weight, the researchers said. “Importantly, there was no correlation between the prescribed dose and the hydroxychloroquine blood level over the range (4.5 to 6.5 mg/kg) used in clinical practice, highlighting the need for personalized hydroxychloroquine drug level-guided therapy and dose adjustment,” they emphasized.
The study findings were limited by several factors, including the observational design and potential confounding from variables not included in the model, as well as the small sample size, single site, and single rheumatologist involved in the study, the researchers noted.
The results suggest that aiming for a blood HCQ level of 1,068 ng/mL can be done safely to help prevent thrombosis in patients with SLE, the researchers said. “Routine clinical integration of hydroxychloroquine blood level measurement offers an opportunity for personalized drug dosing and risk management beyond rigid empirical dosing recommendations in patients with SLE,” they concluded.
The study was supported in part by grants from the National Institutes of Health and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The researchers had no relevant financial conflicts to disclose.

EULAR recommendations define strategies to improve adherence in RMDs
Clinicians who care for patients with rheumatic and musculoskeletal diseases (RMDs) can now refer to a new set of strategies and points to consider from a European League Against Rheumatism (EULAR) task force in building a patient-centered approach to improve adherence to treatments.
Nonadherence to treatments is concerning given that 30%-80% of patients who have RMDs are thought to not follow a recommended treatment plan according to their physicians’ instructions, according to first author Valentin Ritschl of the Medical University of Vienna and colleagues.
“The problem of poor adherence is addressed in some EULAR recommendations/points to consider on the management of specific health conditions or on the role of professionals,” Mr. Ritschl said in an interview. “However, all these recommendations focus on limited aspects of nonadherence and do not cover the multifaceted nature of this phenomenon.”
Mr. Ritschl and colleagues conducted an extensive systematic literature review, the results of which they presented to a task force consisting of a panel of international experts hailing from 12 different countries. The task force included rheumatologists and other health professionals in rheumatology, as well as patient representatives.
The collaboration resulted in investigators crafting a definition of adherence in addition to drafting four overarching principles and nine points to consider, which were published Dec. 18 in Annals of the Rheumatic Diseases.
They defined adherence as “the extent to which a person’s behavior corresponds with the agreed prescription, of pharmacological or nonpharmacological treatments, by a health care provider.”
The four overarching principles emphasize the following concepts: that adherence affects outcomes in people who have RMDs; the importance of shared decision-making, with the understanding that the adherence describes the patient’s behavior “following an agreed prescription”; that numerous factors can affect adherence; and the notion of adherence being a dynamic process that, consequently, requires continuous evaluation.
Among the nine points to consider, Mr. Ritschl and coauthors encouraged all health care providers involved in caring for RMD patients to assume responsibility for promoting adherence. Practitioners should also strive to create an ongoing, open dialogue to discuss adherence, especially in cases in which the patient’s RMD is not well controlled. The patient-centered recommendations include taking into account the patient’s goals and preferences because these greatly contribute to the patient’s ability to adhere to any medication regimen. Another arm of that exploration also requires the medical professional to evaluate any circumstances that could bear a negative effect on the patient’s adherence – whether it be medication access issues related to cost or availability, or functional challenges such as memory, motivation, or complexity of the medication regimen.
Mr. Ritschl believed the task force’s recommendations will add value and help improve overall outcomes in RMD population management.
“Until today, there are no recommendations or points to consider developed in order to support our patients to be adherent to the agreed treatment plan,” he said. “In our project/initiative, we therefore developed for the first time points to consider to detect, assess, and manage nonadherence in people with RMDs.”
Additionally, the recommendations offer some strategic insights to help improve clinical trials because the deleterious effects of nonadherence also affect study results.
Looking ahead, Mr. Ritschl said randomized, controlled trials are necessary to test strategies that might improve adherence. He strongly emphasized the importance of designing future research studies that are heavily patient centered and effective for shared decision-making.
The project was funded by EULAR. Mr. Ritschl reported having no disclosures, but many of his coauthors reported financial relationships with pharmaceutical companies.

They defined adherence as “the extent to which a person’s behavior corresponds with the agreed prescription, of pharmacological or nonpharmacological treatments, by a health care provider.”
The four overarching principles emphasize the following concepts: that adherence affects outcomes in people who have RMDs; the importance of shared decision-making, with the understanding that the adherence describes the patient’s behavior “following an agreed prescription”; that numerous factors can affect adherence; and the notion of adherence being a dynamic process that, consequently, requires continuous evaluation.
Among the nine points to consider, Mr. Ritschl and coauthors encouraged all health care providers involved in caring for RMD patients to assume responsibility for promoting adherence. Practitioners should also strive to create an ongoing, open dialogue to discuss adherence, especially in cases in which the patient’s RMD is not well controlled. The patient-centered recommendations include taking into account the patient’s goals and preferences because these greatly contribute to the patient’s ability to adhere to any medication regimen. Another arm of that exploration also requires the medical professional to evaluate any circumstances that could bear a negative effect on the patient’s adherence – whether it be medication access issues related to cost or availability, or functional challenges such as memory, motivation, or complexity of the medication regimen.
Mr. Ritschl believed the task force’s recommendations will add value and help improve overall outcomes in RMD population management.
“Until today, there are no recommendations or points to consider developed in order to support our patients to be adherent to the agreed treatment plan,” he said. “In our project/initiative, we therefore developed for the first time points to consider to detect, assess, and manage nonadherence in people with RMDs.”
Additionally, the recommendations offer some strategic insights to help improve clinical trials because the deleterious effects of nonadherence also affect study results.
Looking ahead, Mr. Ritschl said randomized, controlled trials are necessary to test strategies that might improve adherence. He strongly emphasized the importance of designing future research studies that are heavily patient centered and effective for shared decision-making.
The project was funded by EULAR. Mr. Ritschl reported having no disclosures, but many of his coauthors reported financial relationships with pharmaceutical companies.

Preserving kidney function in patients with lupus nephritis
Lupus nephritis is a serious complication of lupus for which there is a great unmet therapeutic need. The first step to preserve kidney function is to identify kidney involvement with blood and urine tests, and to assess whether a kidney biopsy is needed. Dr. Richard Furie, Chief of Rheumatology at Northwell Health, shares recommendations for evaluating whether a patient is a candidate for kidney biopsy based on their protein/creatinine ratio and serologic activity.
Dr. Furie also reviews treatment options based on biopsy results, including steroids, immunosuppressive agents, and calcineurin inhibitors, as well as significant findings from the recent BLISS-LN, NOBILITY, and AURORA trials.

FDA expands belimumab indication to adults with lupus nephritis
The U.S. Food and Drug Administration has expanded the indication for belimumab (Benlysta) to adults with active lupus nephritis who are receiving standard therapy.
Roughly 40% of patients with systemic lupus erythematosus (SLE) develop lupus nephritis (LN), which causes inflammation in the kidneys and can lead to end-stage kidney disease.
“Benlysta is the first medicine approved to treat systemic lupus and adults with active lupus nephritis, an important treatment advance for patients with this incurable autoimmune disease,” Hal Barron, MD, GlaxoSmithKline’s chief scientific officer and president of research and development, said in a company news release.
Belimumab IV infusion was first approved in the United States in March 2011 for adults with SLE. The FDA approved belimumab IV infusion for use in children as young as age 5 years with SLE in 2019.
Both the IV and subcutaneous formulations are now indicated in the United States for adults with SLE and LN.
Belimumab is a B-lymphocyte stimulator protein inhibitor that is thought to decrease the amount of abnormal B cells; the latter are thought to play a role in lupus.
The expanded indication for belimumab for patients with LN is based on findings from the BLISS-LN phase 3 trial, published in The New England Journal of Medicine in September.
“Neutralizing B-cell activating factor and down-regulating autoreactive B-cell function in kidneys” represents a “compelling therapeutic approach to lupus nephritis,” the lead investigator of BLISS-LN, Richard Furie, MD, told the online annual Perspectives in Rheumatic Diseases meeting recently.
“In the 4 decades I have been caring for people with lupus, we have not been able to achieve remission in more than just one-third of patients with lupus nephritis, and despite all of our efforts, 10%-30% of patients with lupus kidney disease still progress to end-stage kidney disease,” Dr. Furie, who is chief of the division of rheumatology at Northwell Health, notes in the GSK statement.
“The data from the BLISS-LN study show that Benlysta added to standard therapy not only increased response rates over 2 years, but it also prevented worsening of kidney disease in patients with active lupus nephritis, compared to standard therapy alone,” he added.
BLISS-LN study: Belimumab effect seen mostly in those on MMF
BLISS-LN enrolled 448 adults with biopsy-confirmed active LN. Half were randomly allocated to receive IV belimumab (10 mg/kg) plus standard therapy (mycophenolate mofetil for induction and maintenance or cyclophosphamide for induction followed by azathioprine for maintenance, with steroids) and half to receive placebo plus standard therapy.
At 2 years, significantly more patients in the belimumab group than in the placebo group had a primary efficacy renal response (43% vs. 32%; odds ratio, 1.6; 95% confidence interval, 1.0- 2.3; P = .03).
This primary endpoint was defined as a ratio of urinary protein to creatinine of ≤0.7, an estimated glomerular filtration rate that was no worse than 20% below the value before the renal flare or ≥60 mL per minute per 1.73 m2 of body surface area, without use of rescue therapy.
The risk for a renal-related event or death was also significantly lower among patients who received belimumab than among those who received placebo (hazard ratio, 0.51; P = .001). The safety profile of belimumab was consistent with that observed in prior studies.
But in a commentary that accompanied the publication of BLISS-LN, editorialists noted that “most of the treatment effect was seen in patients who had received mycophenolate mofetil. No benefit was present in the subgroup of patients who received cyclophosphamide-azathioprine.”
In addition, induction treatment was not randomly assigned, editorialists Michael Ward, MD, MPH, and Maria Tektonidou, MD, PhD, noted.
“If patients with more severe nephritis were preferentially treated with cyclophosphamide, a likely inclination among most physicians, the trial may be telling us that belimumab enhances responses only among less severely affected patients,” observed Dr. Ward, who is with the National Institutes of Health, and Dr. Tektonidou, of the National and Kopodistrian University, in Athens.

High-need, high-cost lupus patients described for first time
according to a retrospective analysis of hospitalization data from a tertiary care center.
“The identification of the HNHC [high-need, high-cost] cohort and the risk factors for hospitalizations for this cohort will help pave the way to develop programs that improve the quality of care for high-risk lupus patients and [at the same time] lower the cost of care for all lupus patients,” first author Allen Anandarajah, MBBS, and colleagues at the University of Rochester (N.Y.) wrote in Arthritis Care & Research.
Hospitalizations and readmissions are known to be common in patients with SLE, the authors said, and they “account for a large proportion of the direct costs associated with the care of this disease.”
“While HNHC cohorts have been described with other chronic diseases, this report is the first to describe the existence of such a cohort in the SLE population,” the researchers said.
To see if a small group of SLE patients would constitute the majority of hospitalizations and consequently the costs of such care, Dr. Anandarajah and associates analyzed data from 202 SLE patients and their 467 hospitalizations at the University of Rochester–affiliated Strong Memorial Hospital during July 1, 2013, to June 30, 2016. The patients had a mean age of 46 years and included 183 females. A total of 46.5% were White, 43.1% were African American, 6.9% were Hispanic, and 3.5% were of Asian descent. These patients had median lengths of stay of 7 days per SLE patient and 4 days per admission, with median costs of $19,271 per patient and $14,375 per admission.
The researchers identified 44 patients (22%) who accounted for 275 admissions (59%) during the 3-year period. This group’s median of 4 admissions per patient was significantly higher than the median of 1 recorded in all the other hospitalized SLE patients, as was its number of readmissions within 30 days (105 total and median of 1 vs. 11 total and median of 0). The high-risk SLE patients spent a significantly greater amount of time in the hospital than did other patients (median of 30 days vs. 5 days), and their median cost was more than six times as great ($95,262 vs. $14,360). High-risk patients’ median cost per admission also was significantly greater ($19,376 vs. $12,833).
Infections were the most common cause of hospitalization among both high-risk patients and others (28% vs. 23%, respectively) and the rate of involvement of different organ systems as a cause for hospitalization were similar between the groups, except that patients at lower risk significantly more often had gynecologic/obstetric concerns (10% vs. 2%) or nervous system involvement (16% vs. 5%), and high-risk patients were significantly more likely to have gastrointestinal complaints (20% vs. 8%).
Clinically, high-risk patients had significantly higher median scores on the Systemic Lupus International Collaborating Clinics Damage Index and the Comorbidity Index, as well as a significantly higher median level of double-stranded DNA. However, they had no differences in complement factor levels or body mass index.
The high-risk patients also were younger (mean of 42 vs. 46 years) and were diagnosed at a younger mean age (26 vs. 31 years). More high-risk patients were African American (55% vs. 40%) and were more likely to live in areas identified with poverty (50% vs. 29%).
A multivariate analysis that controlled for relevant confounders showed that high-risk patients had a 10 percentage point lower medication possession ratio, which is an indicator of whether a patient had adequate medication supply in a given time frame. High-risk patients overall had a higher average number of medications to treat lupus.
“Our findings underscore the importance of identifying HNHC SLE patients when designing and implementing interventions to lower hospitalizations and improve the quality of care for lupus patients. Furthermore, it is imperative that we develop programs to address the modifiable social and behavioral factors in addition to providing high-quality clinical care targeted for this group,” the researchers wrote.
Some of the limitations in the generalizability of the results include the use of data from a large tertiary medical center serving a large catchment area, with a consequently sicker group of patients, and the potential to miss readmissions to other nearby hospitals. However, “as one of the few centers [in the region] that provides in-patient rheumatology care ... it is less likely that patients would have sought care elsewhere,” they noted.
The study involved no outside source of funding, and the authors had no relevant conflicts of interest.

A Review of ACR Convergence Abstracts on Systemic Lupus Erythematosus
The American College of Rheumatology hosted its first-ever all-virtual annual meeting this year. Convergence 2020 highlighted several important treatment abstracts related to systemic lupus erythematosus.
Dr Michelle Petri, of Johns Hopkins University, reports on the use of hydroxychloroquine, which was not found to be associated with QTc length in a large cohort of patients with lupus and rheumatoid arthritis. This is notable because hydroxychloroquine was implicated in ventricular arrhythmias in patients with COVID-19 who were also given azithromycin.
Dr Petri also looks at the results of two trials focusing on the effects of belimumab and obinutuzumab on renal outcomes.
In the belimumab trial, the primary outcome was a 700-mg reduction in the urine protein to creatinine ratio, and it met that outcome with a 10.8% delta that was statistically significant. It also met the complete renal response outcome of less than 500 mg with a 10% delta, which is statistically significant.
In the other study, obinutuzumab showed a marked improvement over rituximab as a B-cell depleter.
The completion of the phase 2 trial means that there are now 2 years of data showing a 19% delta between obinutuzumab and standard-of-care treatment.
Finally, Dr Petri highlights two studies focusing on nonrenal lupus and the use of both BIIB059 and iberdomide.

Slow taper off antimalarial is best to avoid lupus flare during remission
Slowly tapering off – or remaining on – antimalarial medications can help prevent disease flare in patients with systemic lupus erythematosus (SLE) who’ve achieved clinical remission for at least a year, according to a new study that was presented at the virtual annual meeting of the American College of Rheumatology.
“Except in the setting of toxicity, cessation of antimalarial medication in patients with disease quiescence is feasible using a slow taper,” lead author Danaë Papachristos, MBBS, said during an oral abstract presentation at the online meeting. Dr. Papachristos conducted the research while a clinical and research fellow at the University of Toronto’s lupus clinic, but is now a consultant rheumatologist at the Wesley Hospital in Brisbane, Queensland, Australia.
To investigate flare in patients with SLE who were on or recently off antimalarial medications (AMs), the researchers identified 1,573 potential participants from a long-term observational cohort study at the university’s lupus clinic. From that larger group, 88 cases – patients who achieved clinical remission for at least a year and stopped taking AMs – were matched to at least one control – patients who also achieved remission and continued on medication. Most cases were also matched to a second control, bringing the total number to 173. All patients had at least 2 years of follow-up.
Flare was defined as any increase in the SLEDAI-2K score, with major flare defined as an increase of 4 or more. Patients in the case group were roughly 44 years old, compared with an average age of 46 in the control group. Both groups were almost entirely female and largely white. Reasons for withdrawal in the case group included self-cessation, disease quiescence, and retinal, mucocutaneous, or cardiac toxicities. Twenty participants in the case group reported AM toxicity, compared with four controls.
Dr. Papachristos noted in her presentation that the toxicity disparity was expected, “because controls are those who continue their medication, and most patients who have toxicity will stop their medication.”
Disease flare occurred in 61.4% of cases, compared with 45.1% of controls (P = .002), with the most common types being cutaneous and musculoskeletal flares. After multivariate analysis, the risk of flare more than doubled for those who ceased AMs (odds ratio, 2.26; 95% confidence interval, 1.24-4.11; P = .008). More than half of the cases (n = 46) restarted AMs after withdrawal, which was largely due to disease flare. Of the patients who restarted due to flare, 88% either recaptured control or improved, and the remaining 12% had further flares.
Of the 88 patients in the case group, 51 abruptly withdrew AMs while 37 tapered off. Patients who tapered had fewer flares (45.9%), compared with patients who withdrew abruptly (72.6%). After multivariate analysis, the risk of flare more than tripled for the abrupt withdrawal group (OR, 3.42; 95% CI, 1.26-9.26; P = .016). Fewer patients who tapered later restarted AMs, compared with the abrupt withdrawal group (37.8% vs. 62.7%; P = .02).
When asked about other differences in medications between the two groups, Dr. Papachristos answered: “We didn’t look into that specifically. We did look at those patients who were on prednisone and on any immunosuppression, although we didn’t look at specific therapies. Those variables were adjusted for in the analysis, and it didn’t make any difference if patients were on immunosuppression or prednisone at the point of index date.
“But we would like to look into the different forms of immunosuppression,” she added, “just to see if that made any difference.”
Withdrawing hydroxychloroquine in older patients
Older patients with SLE who discontinue their use of hydroxychloroquine (HCQ) are also not at increased risk of disease flare, according to a retrospective chart review from rheumatologists Ruth Fernandez-Ruiz, MD, and Peter M. Izmirly, MD, of New York University (Arthritis Res Ther. 2020;22:191. doi: 10.1186/s13075-020-02282-0).
“We wanted to focus on older patients who may have a lower risk of flaring and a higher risk of side effects from the drug,” Dr. Fernandez-Ruiz said in an interview.
The doctors embarked on the study after noticing eye and heart toxicities in certain older patients. They matched 26 lupus patients who had been on HCQ for at least 5 years before discontinuing the drug with 32 control patients who remained on HCQ, ultimately finding that withdrawal had no effect on their risk of lupus flares within a year.
“After starting a drug, the second question most people ask, after ‘What are the side effects?’ is ‘How long do I have to be on this?’ ” Dr. Izmirly said in an interview. “These patients are having side effects associated with long-term HCQ use. And we were noticing that, after you stop the drug, despite what you’re taught, they weren’t flaring.”
Only five patients from each group – 19.2% of the withdrawal group and 15.6% of the continuation group – experienced a flare (OR, 1.28; 95% CI, 0.31-5.30; P = .73). Most of the flares were cutaneous and musculoskeletal in nature, and no severe flares occurred in either group.
“On each side, the overall flare rate was not that high, and they were all relatively mild,” Dr. Izmirly said.
The two doctors acknowledged their study’s smaller sample size, compared with the study by Papachristos and colleagues, along with the advanced age of their patient population, which limits the generalizability of their findings. “We selected patients who had a very low disease activity to begin with, and who were older,” Dr. Fernandez-Ruiz noted.
That said, they reinforced the scarcity of existing research on this subset of lupus patients, one that will only continue to grow.
“Older [patients with] lupus,” Dr. Izmirly said, are “an understudied demographic.”
One of the authors of the study presented at ACR 2020 acknowledged receiving research support and consulting fees from various pharmaceutical companies. The HCQ study was supported by a grant from the National Institute of Arthritis and Musculoskeletal and Skin Diseases; its authors declared no conflicts of interest.
