Gliederung

Text

Introduction: Cutaneous lupus has a wide spectrum of clinical manifestations, which often only partially respond to conventional therapies. Among the cytokines highly implicated in the pathogenesis of cutaneous lupus, type I interferons (IFNs) play a prominent role. Type I IFN-stimulated genes and proteins are typically upregulated in both the skin and blood of lupus patients. Type I IFN receptor blockade with anifrolumab is EMA- and FDA-approved for the treatment of SLE.

Methods: Here, we evaluated clinical efficacy of anifrolumab therapy in treatment refractory cutaneous lupus lesions in 5 SLE patients and the correlation with their type I interferon score.

Results: We treated 5 patients with cutaneous involvement of systemic lupus (2 SCLE, 1 ACLE, 2DLE) with anifrolumab. Previously refractory skin lesions showed rapid improvement with 50% reduction in median CLASI-A after one month and completely resolved within 3–6 months of treatment. Relief of cutaneous symptoms was associated with improvement of life quality. In parallel to clinical response, we observed a reduction in IFN-scores determined by measuring the mRNA expression of seven IFN-stimulated genes in blood. IFN scores kept declining over 6 to 12 months of treatment, and two patients reached levels comparably to healthy controls after 6 months. Our limited data suggest that interferon score declines slower compared to the rapid relief of skin lesions. This might indicate that the cutaneous response is not entirely dependent on systemic reduction of interferon stimulated genes in blood.

Conclusion: In conclusion these data indicate rapid efficacy of anifrolumab in cutaneous lupus in parallel with a decline in interferon score in blood.
