Dupilumab-associated arthralgia in patients with aspirin-exacerbated respiratory disease: a case series

We report a series of eight patients with AERD who developed arthralgias after initiating dupilumab. We found that 8 patients out of the 160 (5%) with AERD who have been prescribed dupilumab at our center developed possible dupilumab-associated arthralgias. Of the patients who underwent extensive rheumatologic work-up, no etiology of the joint symptoms was identified. All 8 patients experienced significant improvement in upper and lower respiratory tract symptoms and ultimately decided to continue dupilumab even with the possible dupilumab-associated arthralgias. Out of the eight subjects, the arthralgias spontaneously resolved in five of the patients. The cause of the dupilumab-associated arthralgias is unknown, but one possible explanation is a Type 1 or Type 3 “escape” with inhibition of IL-4Ra. Read more here.
