High Systemic Type I Interferon Activity Is Associated with Active Class III/IV Lupus Nephritis
The Journal of Rheumatology 2022; 49:388–97 DOI 10.3899/jrheum.210391
Iwamoto, et al. aimed to determine the association of serum IFN activity with subtypes of lupus nephritis. This study suggests that systemic high type I IFN in SLE is involved in the pathogenesis of severe class III/IV LN and contributes to severe kidney involvement in European-American patients with SLE. However, this effect was independent of anti‑dsDNA antibody status and complement levels. Expression of type I IFN was not found to be clearly related to plasmacytoid dendritic cell infiltration, although it did directly stimulate podocytes to induce chemokines and molecules related to podocyte injury.
Anifrolumab efficacy and safety by type I interferon gene signature and clinical subgroups in patients with SLE: post hoc analysis of pooled data from two phase III trials
Ann Rheum Dis. 2022; 0:1–11. doi: 10.1136/annrheumdis-2021-221425
IFN-I signalling plays a key role in SLE pathogenesis, and anifrolumab has demonstrated inhibitory effects on IFN-I signalling in patients with SLE. Vital, et al. characterised efficacy and safety of anifrolumab in patients with moderate-to-severe SLE based on interferon gene signature, demographic and clinical subgroups using data pooled from the Phase III TULIP-1 and -2 trials.
