It has been suggested that MS can be triggered by certain viruses; however, human immunodeficiency virus (HIV) infection is associated with reduced incidence of MS. We present the case of a young patient diagnosed with active relapsing-remitting MS whose clinical course substantially improved following HIV infection and treatment. The patient achieved no evidence of disease activity status without any disease-modifying drugs. Both HIV-induced immunosuppression and antiretroviral therapy may have attenuated the clinical course in this patient. PB Sage Publications Ltd.
