Clinical Efficacy of Belimumab in Patients with Systemic Lupus Erythematosus and Headache. A Report of Two Cases
Abstract Intractable headache, one of the manifestations of neuropsychiatric systemic lupus erythematosus, is difficult to diagnose and determine an effective treatment. In addition to conventional therapy according to the type of headache, the treatment should be conducted considering the disease activity of systemic lupus erythematosus rather than the headache. We report two patients with intractable headache who were successfully treated using belimumab therapy. The headaches in both patients were relieved after 2 weeks of belimumab administration. The neutralization of B lymphocyte stimulator and reduced production of cytokines from B lymphocytes might contribute to the early effects. The potential benefits of using belimumab as an additional immunosuppressant for treating intractable headache complicated with systemic lupus erythematosus have been discussed.
