Two Cases of Primary Sjögren's Syndrome Presenting as Relapsing-Remitting Multiple Sclerosis

Sjögren's syndrome is a slowly progressive autoimmune disorder that predominantly affects major exocrine glands, and may also involve the central nervous system (CNS). It is sometimes very difficult to differentiate the CNS Sjögren's syndrome from multiple sclerosis. Here, we report two cases of Sjögren's syndrome who developed variable neurological symptoms mimicking the relapsing-remitting form of multiple sclerosis. There had been several relapses during the course of interferon-beta treatment but no relapses have occurred after steroid maintenance therapy.ope
