Abstract:
Hypocomplementemic urticarial vasculitis (HUV) is a rare autoimmune disorder characterized by recurrent urticarial eruptions, hypocomplementemia and systemic involvement. This disease is prone to misdiagnosis, and its systemic manifestations may include arthritis, abdominal pain, renal involvement, chronic obstructive pulmonary disease and so on. Herein, we report a case of HUV presenting with recurrent abdominal pain, generalized wheals and arthralgia. Laboratory tests revealed decreased complement levels, skin histopathology was consistent with leukocytoclastic vasculitis, and imaging examinations indicated spondyloarthritis, thus confirming the diagnosis of HUV. The patient initially received systemic glucocorticoids combined with colchicine, whereas recurrent rash and arthralgia persisted. Tofacitinib (a Janus kinase inhibitor) and methotrexate were subsequently added to the regimen, leading to remission of symptoms. This case suggests that tofacitinib may serve as a potential therapeutic alternative for patients with HUV who respond poorly to glucocorticoids.
