Filgotinib gegen Kalzinose bei Zentromer-Antikörper-positiver systemischer Sklerose
摘要
Centromere-antibody-positive limited cutaneous systemic sclerosis (LCSSc) is a common disease. It generally takes a benign course, but can still considerably reduce quality of life. Our patient—a woman born in 1987 who was first diagnosis 2017—suffered from pain and declining hand function due to sclerodactyly and calcinosis. Methotrexate (MTX) and analgesics were not effective. After commencing off-label treatment with filgotinib, the patient reported rapid improvement. An X-ray after 8 months showed a reduction in calcinosis load. Filgotinib is well tolerated. Sclerodactyly has resolved, and hand function continues to improve. The clinical and radiological response merit further enquiry of Janus kinase (JAK) inhibitors in centromere-antibody-positive LCSSc.
