Now published: The 2025 ACR Guideline for the Treatment of Systemic Lupus Erythematosus 📄 Read the paper: acr.tw/47mkegj ℹ️ See additional content and resources on this guideline at acr.tw/4mbHK4W #Medsky #Rheumsky #Rheumatology
Overview of the recommended management for systemic lupus erythematosus (SLE). This schematic illustrates the approach to SLE treatment, with organ-specific therapies presented in separate boxes and stratified by disease severity. 
The order of the medications in each box does not indicate preference unless noted otherwise. 
Lupus nephritis treatment is addressed in the 2025 American College of Rheumatology Guideline for the Screening, Treatment, and Management of Lupus Nephritis. 
ABBREVIATIONS: 
ACLE, acute cutaneous lupus erythematosus; SCLE, subacute cutaneous lupus erythematosus; CCLE, chronic cutaneous lupus erythematosus; CNI, calcineurin inhibitor (cyclosporin or tacrolimus); HCQ, hydroxychloroquine; CQ, chloroquine; CCB, calcium channel blockers; IL-1 blockade, Interleukin-1 blockade; IS, immunosuppressive therapy; IV CYC, intravenous cyclophosphamide; IVIG, intravenous immunoglobulins; LCV, leukocytoclastic vasculitis; MPAA, mycophenolic acid analogs; NSAIDs, non-steroidal anti-inflammatory drugs; PDE5i, phosphodiesterase type 5 inhibitors; PLEX, plasma exchange.
FOOTNOTES:
** In CLE, switch HCQ to CQ with the intention of changing back to HCQ once the rash is under control.
† Azathioprine may be used when pregnancy is planned. Based on the Voting Panel members’ clinical experience, anifrolumab has a more rapid onset of benefit and a greater likelihood of response than belimumab.
⁂ MPAA may be preferable over Azathioprine
§ Alternative agents such as leflunomide are occasionally used for those with arthritis 
‖ Evidence for severe neurologic syndromes was largely limited to IV CYC
