  "abstract": "Objectives SLE associated with immune checkpoint inhibitors (ICIs) is rare, and a comprehensive profile of ICI-induced SLE remains poorly characterised. This study aimed to explore the potential association between ICIs and SLE and characterise clinical features.Methods We extracted adverse event reports of patients with cancer with SLE from the FAERS (US Food and Drug Administration Adverse Event Reporting System) database (Q1 2011–Q4 2024). A disproportionality analysis was conducted using the reporting OR (ROR) and the information component, with adjusted ROR calculated via logistic regression to control for confounders.Results 146 066 ICI-related adverse events cases from patients with cancer were identified. Among these, 209 (median (IQR) age 63 (55.3–71.7) years; 106 (51%) female) cases of SLEs were reported. Our analysis detected significant positive signals for SLE associated with ICIs overall, particularly for anti-programmed cell death protein 1 (PD-1) and anti-programmed death-ligand 1 therapy. Eight positive signals of SLEs were identified, predominantly cutaneous lupus and SLE. The risk of ICI-related SLEs was significantly higher in females than in males. However, age and chemotherapy were not significant risk factors for the incidence of ICI-related SLEs. The risk was higher with anti-PD-1 therapy compared with other ICI therapies. Patients with lung cancer, melanoma or breast cancer appeared to be at higher risk. Most patients experienced serious outcomes, with a mortality rate of 4.31% (nine cases).Conclusion This first pharmacovigilance study identified a significant association between ICI use and SLEs, suggesting ICIs may constitute a novel class of drug-induced SLE triggers. Personalised long-term safety monitoring for ICIs is warranted for high-risk patients (eg, females, anti-PD-1 recipients).",
