Abstract
Dermatomyositis (DM) is a multisystem inflammatory condition with diverse cutaneous and systemic symptoms. Both muscle and skin involvement are common and can occur simultaneously or sequentially, or individuals can have muscle- or skin-limited disease. Skin involvement in DM can be extensive, and pruritus is one of the most problematic symptoms for the patient. Its pathophysiology is poorly understood, making management challenging for clinicians. A limited number of therapeutic agents target pruritus in DM, adding another challenge for clinicians. Previous case reports suggest dupilumab as a treatment for pruritus in DM. However, our patient experienced no relief. Our patient’s failure of dupilumab suggests that its targets, interleukin (IL)-4 and IL-13, do not play a significant role in the pruritus of DM. It is possible that targeting other small molecules in inflammatory pathways could greatly alleviate pruritus for individuals with DM. Further studies need to be conducted to extrapolate the mechanism of pruritus in DM so that individuals with DM can find more significant relief.
