Systemic lupus erythematosus induced by interferon β1 therapy in a patient with multiple sclerosis

Abstract: Drug-induced lupus erythematosus is defined as a lupus-like syndrome temporally related to a drug exposure. We report a 34-year-old woman with multiple sclerosis who developed, while being treated with interferon β-1a, myalgia and associated with wrist synovitis. Clinical and immunologic investigations were in favor of systemic lupus erythematosus. Interferon therapy was maintained. Under corticosteroids and antipaludeen treatment, the patient did not develop any other lupic manifestations.

“… 21 However, few case reports have shown the development of SLE in patients with MS treated with INF. 22 24 This contrasts with what happened in our patient, since the symptoms of SLE were present when the medication was withdrawn and worsened despite receiving treatment with hydroxychloroquine. We believe that previous infection with the dengue virus could have triggered the expression of type I INF and the subsequent development of SLE as demonstrated in studies in which SLE developed in individuals who were exposed to live virus vaccines.…”

“…SLE is a multisystemic autoimmune disease that can manifest itself in numerous pathological outcomes affecting skin, joints, lung, kidney and the CNS 38 . Indeed, it was reported in the literature that demyelinating disease in SLE in particular has the propensity to be accidentally misdiagnosed as other CNS affecting diseases such as MS 39 , and a case report showed an induction of SLE by interferon beta-1 treatment of a MS patient 40 , thereby demonstrating the potential autoimmune-link between these two diseases. RA, JIA and ERA are joint-affecting autoimmune disorders and are, like SLE, underpinned by chronic inflammation 41 .…”

“…Nonetheless, case studies reporting drug related (mainly due to IFN-b) autoimmune rheumatic diseases (and in particular SLE) led several authors to conclude that unmasking of underlying autoimmune rheumatic disease cannot be taken lightly over the course of MS [26][27][28][29][30]. The same point has been raised very recently for AIH and other AiLDs diagnosed in patients with MS [9].…”
