New EULAR lupus recommendations advise using biologics, tapering steroids


 

AT EULAR 2023

– Treatment of systemic lupus erythematosus with biologics may enable steroid tapering while ensuring the achievement of remission or low disease activity in more patients with fewer flares and less organ damage, as well as leading to better responses if used early, according to the latest recommendations on the management of SLE from the European Alliance of Associations for Rheumatology (EULAR).

Dimitrios Boumpas, MD, president of the Athens Medical Society and chair of the European Task force on SLE, presented the recommendations at the annual European Congress of Rheumatology. “Although steroids save lives, it is at the expense of excessive collateral damage. They are better for short-term use as a rescue or bridging therapy but may be used in some patients at 5 mg/day of prednisone or less, rather than the previous 7.5 mg/day,” he emphasized.

The 2023 recommendations cover new treatment strategies with more ambitious goals, new data on adverse effects of chronic glucocorticoid use, and newly approved agents and combination therapies.

“Most importantly, we sourced help from experts from all over the world,” said Dr. Boumpas, describing the task force that included 35 rheumatologists, 5 nephrologists, 2 methodologists, 2 patient representatives, and 2 fellows, all brought together from across Europe, North America, Asia, and Australia.

Over 7,000 papers were reviewed, with 437 included in the systematic literature review to inform the updated recommendations.

Session moderator Robert Landewé, MD, PhD, professor of clinical immunology and rheumatology at the University of Amsterdam, said that “the underlying heterogeneity and multisystem involvement of SLE can make it difficult to demonstrate and know which drugs work in the condition. However, these latest recommendations should encourage greater confidence to taper steroids early on and perhaps consider new biologic drugs, so that more patients can achieve better results sooner to prevent flares and organ damage, improve prognosis, and enhance their quality of life.”

Dr. Boumpas provided a summary of the overarching principles that guide the recommendations. These say that SLE requires multidisciplinary individualized management; disease activity should be assessed at each visit; nonpharmacologic interventions such as sun protection, smoking cessation, and following a healthy diet are all important for improving long-term outcomes; pharmacologic interventions are to be directed by patient characteristics, type and severity of organ involvement, treatment-related harms, and patient preferences, among other factors; and early SLE diagnosis is essential to prevent flares and organ damage, improve prognosis, and enhance quality of life.

Referring to each recommendation statement in turn, Dr. Boumpas provided a detailed description of each, and highlighted any changes since the 2019 recommendations.

Hydroxychloroquine, glucocorticoids as bridging therapy, and biologics

Referring to statement 1, Dr. Boumpas reported that hydroxychloroquine should be a first-line therapy at a dose of 5 mg/kg, but this dose should be individualized based on risk of flare and retinal toxicity. “There was some discussion about monitoring blood levels, but this was to ensure adherence only,” said Dr. Boumpas.

Continuing to statement 2, he added, “here is one change. With chronic use of glucocorticoids, the maintenance dose is 5 mg/day or less or prednisone equivalent. This pertains to both new onset and relapsing disease.” Previous recommendations advised a maintenance dose of 7.5 mg/day or less.

But he pointed out that “we are discussing using glucocorticoids in lupus as a bridging therapy only, for short, limited periods of time. We should shy away from chronic use of glucocorticoids and only use them for 3 months, and to do this we need to use glucocorticoid-sparing strategies.”

This led to statement 3, which refers to glucocorticoid-sparing strategies. Dr. Boumpas explained that, in patients who are not responding to hydroxychloroquine or unable to reduce glucocorticoids further during chronic use, add immunosuppressive agents, such as methotrexate and/or biologics (for example, belimumab [Benlysta] or anifrolumab [Saphnelo]).

“To allow flexibility for patients and clinicians, it isn’t necessary to use DMARDs [disease-modifying antirheumatic drugs] first if you prefer biologics,” he continued. “We are becoming more liberal with the use of biologics because there are new data that confirm the efficacy of belimumab in extrarenal SLE, plus good data with 3-year extension with anifrolumab.”

Statement 4 says that for patients with organ- or life-threatening disease, intravenous cyclophosphamide, “our old friend,” should be considered, while in refractory cases, rituximab may be considered, Dr. Boumpas said. “It’s okay to use cyclophosphamide. It isn’t a sin.”

Statement 5 refers to skin disease, and Dr. Boumpas explained that good data suggested that biologics help, including both belimumab and anifrolumab.

Nothing has changed with statement 6 concerning neuropsychiatric lupus, said Dr. Boumpas. “Glucocorticoids, immunosuppressive, and antithrombotic therapies should be considered.”

Regarding hematologic disease (statement 7), he said, “the new kid on the block is MMF [mycophenolate mofetil]. For acute treatment, still use the same drugs, including rituximab, but for maintenance you may use rituximab, azathioprine, MMF, or cyclosporine.”
